[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent Application No. 63 / 443,274, filed on February 3, 2023, entitled “DEVICES, METHODS, AND GRAPHICAL USER INTERFACES FOR DEVICE POSITION ADJUSTMENT”; and U.S. Provisional Patent Application No. 63 / 470,925, filed on June 4, 2023, entitled “DEVICES, METHODS, AND GRAPHICAL USER INTERFACES FOR DEVICE POSITION ADJUSTMENT”; and U.S. Patent Application No. 18 / 405,893, filed on January 5, 2024, entitled “DEVICES, METHODS, AND GRAPHICAL USER INTERFACES FOR DEVICE POSITION ADJUSTMENT”.

[0002] The present disclosure generally relates to computer systems that provide computer-generated experiences in communication with one or more display generation components and one or more input devices, including but not limited to electronic devices that provide virtual reality experiences and mixed reality experiences via displays. Background Art

[0003] In recent years, the development of computer systems for augmented reality has increased significantly. Example augmented reality environments include at least some virtual elements that replace or augment the physical world. Input devices for computer systems and other electronic computing devices, such as cameras, controllers, joysticks, touch-sensitive surfaces, and touchscreen displays, are used to interact with virtual / augmented reality environments. Example virtual elements include virtual objects such as digital images, videos, text, icons, and control elements such as buttons and other graphics. Summary of the Invention

[0004] Some methods and interfaces for adjusting device positioning are cumbersome, inefficient, and limited. For example, systems that provide insufficient, unclear, or confusing feedback for accurate device positioning are complex, tedious, and error-prone, placing a significant cognitive burden on users and detracting from the experience in virtual / augmented reality environments. Furthermore, these methods can take longer than necessary, wasting computer system energy. This latter consideration is particularly important in battery-powered devices.

[0005] Therefore, there is a need for computer systems with improved methods and interfaces for providing feedback related to device positioning adjustments that make interaction with the computer system more efficient and intuitive for users. These methods and interfaces optionally supplement or replace conventional methods for providing feedback related to device positioning adjustments. Such methods and interfaces reduce the amount, extent, and / or nature of input from the user by helping the user understand the connection between the input provided and the device's response to those inputs, thereby creating a more efficient human-computer interface.

[0006] The disclosed system reduces or eliminates the aforementioned drawbacks and other problems associated with user interfaces for computer systems. In some embodiments, the computer system is a desktop computer with an associated display. In some embodiments, the computer system is a portable device (e.g., a laptop, tablet, or handheld device). In some embodiments, the computer system is a personal electronic device (e.g., a wearable electronic device such as a watch or head-mounted device). In some embodiments, the computer system has a touchpad. In some embodiments, the computer system has one or more cameras. In some embodiments, the computer system has a touch-sensitive display (also known as a "touch screen" or "touchscreen display"). In some embodiments, the computer system has one or more eye tracking components. In some embodiments, the computer system has one or more hand tracking components. In some embodiments, in addition to the display generation component, the computer system also has one or more output devices, including one or more tactile output generators and / or one or more audio output devices. In some embodiments, the computer system has a graphical user interface (GUI), one or more processors, memory, and one or more modules, programs or instruction sets stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI through contacts and gestures of a stylus and / or finger on a touch-sensitive surface, movement of the user's eyes and hands in space relative to the GUI (and / or computer system) or the user's body (as captured by a camera and other motion sensors), and / or voice input (as captured by one or more audio input devices). In some embodiments, the functions performed by the interaction optionally include image editing, drawing, presentations, word processing, spreadsheet creation, playing games, making and receiving calls, video conferencing, sending and receiving emails, instant messaging, test support, digital photography, digital video recording, web browsing, digital music playback, note-taking, and / or digital video playback. Executable instructions for performing these functions are optionally included in a transient and / or non-transient computer-readable storage medium or other computer program product configured for execution by one or more processors.

[0007] There is a need for electronic devices having improved methods and interfaces for providing feedback related to device positioning adjustments. These methods and interfaces can supplement or replace conventional methods for providing feedback related to device positioning adjustments. Such methods and interfaces reduce the amount, extent, and / or nature of input from the user and produce a more efficient human-computer interface. For battery-powered computing devices, such methods and interfaces conserve power and increase the time between battery charges.

[0033] In some embodiments, the present disclosure relates to a user interface for providing an extended reality (XR) experience to a user.

[0034] The systems, methods, and GUIs described herein improve user interface interactions with virtual / augmented reality environments in several ways.

[0035] In some embodiments, a computer system detects a positioning of at least a portion of the computer system relative to a user's face (e.g., relative to a portion of the user's face (e.g., relative to the user's eyes, nose, and / or forehead)). In some embodiments, proper positioning of the computer system relative to the user's face assists in providing an improved experience to the user, for example, by allowing the user to properly view displayed content and / or by allowing the user to provide more accurate user input (e.g., eye-based and / or gaze-based input). Thus, in some embodiments, when the computer system detects that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions (e.g., the portion of the computer system is too far to the left, too far to the right, too high, and / or too low relative to the user's face), the computer system optionally outputs a first alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies the one or more error conditions. In some embodiments, when the computer system detects that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions and the computer system satisfies the corresponding criteria (for example, the computer system is not displaying immersive content or is not in the first state), the computer system outputs a first alert, and when the computer system detects that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions and the computer system does not satisfy the corresponding criteria (for example, the computer system is displaying immersive content and / or is in the first state), the computer system waits to output the first alert until the computer system actually satisfies the corresponding criteria.

[0036] In some embodiments, a computer system detects the positioning of a portion of the computer system relative to a portion of a user's body. In some embodiments, proper positioning of the computer system relative to the user's face assists in providing an improved user experience, for example, by allowing the user to properly view displayed content and / or allowing the user to provide more accurate user input (e.g., eye-based and / or gaze-based input). Thus, in some embodiments, when the computer system detects that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions (e.g., the portion of the computer system is too far to the left, too far to the right, too high, and / or too low relative to the user's face; and / or the computer system is too close to or too far from the user's face), the computer system displays a notification. In some embodiments, certain types of errors are considered more significant or severe than other types of errors. Thus, when the error condition is a first type of error condition, which is considered a more severe error, the computer system displays a first alert; and when the error condition is a second type of error condition, which is considered less severe, the computer system displays a second alert, which is different from the first alert.

[0037] Figures 1A to 6A description of an example computer system for providing an XR experience to a user is provided. Figures 7A-7H illustrate example techniques for providing feedback related to device positioning adjustments in some embodiments. Figure 8 7A to 7H are flowcharts of a method for providing feedback related to device positioning adjustments in some embodiments. Figure 8 in the process. Figures 9A to 9G Example techniques for providing feedback regarding device positioning adjustments in some embodiments are illustrated. Figure 10 is a flow chart of a method for providing feedback related to device positioning adjustments in some embodiments. Figures 9A to 9G The user interface in Figure 10 in the process.

[0038] The processes described below enhance device operability and make the user-device interface more efficient (e.g., by helping users provide appropriate input and reducing user errors when operating / interacting with the device) through various techniques, including providing improved visual feedback to the user, reducing the number of inputs required to perform an action, providing additional control options without cluttering the user interface with additional display controls, performing an action without further user input when a set of conditions has been met, improving privacy and / or security, providing a richer, more detailed, and / or more realistic user experience while conserving storage space, and / or additional techniques. These techniques also reduce power usage and extend the device's battery life by enabling users to use the device more quickly and efficiently. This conserves battery power and, therefore, weight, improving the device's ergonomics. These techniques also enable real-time communication, allow the use of fewer and / or less precise sensors, resulting in a more compact, lighter, and less expensive device, and enable the device to be used in a variety of lighting conditions. These techniques reduce energy usage and thereby reduce the heat emitted by the device, which is particularly important for wearable devices where if the device generates too much heat well within the operating parameters of the device components, it may become uncomfortable for the user to wear the device.

[0039] Furthermore, in methods described herein where one or more steps depend on one or more conditions being satisfied, it should be understood that the method can be repeated in multiple iterations such that, during the repetitions, all conditions governing the steps in the method are satisfied in different iterations of the method. For example, if a method requires performing a first step (if a condition is satisfied) and performing a second step (if the condition is not satisfied), one of ordinary skill will understand that the stated steps should be repeated until both the condition is satisfied and the condition is not satisfied (in either order). Thus, a method described as having one or more steps that depend on one or more conditions being satisfied can be rewritten as a method that repeats until each condition described in the method is satisfied. However, this does not require the system or computer-readable medium to state that the system or computer-readable medium contains instructions for performing contingent operations based on the satisfaction of the corresponding one or more conditions, and thus can determine whether a possible condition has been satisfied without explicitly repeating the steps of the method until all conditions governing the steps in the method are satisfied. One of ordinary skill in the art will also understand that, similar to methods with contingent steps, the system or computer-readable storage medium can repeat the steps of the method as many times as necessary to ensure that all contingent steps have been performed.

[0040] In some embodiments, as Figure 1A As shown, an XR experience is provided to a user via an operating environment 100 including a computer system 101. The computer system 101 includes a controller 110 (e.g., a processor of a portable electronic device or a remote server), a display generation component 120 (e.g., a head-mounted device (HMD), a display, a projector, a touch screen, etc.), one or more input devices 125 (e.g., an eye tracking device 130, a hand tracking device 140, other input devices 150), one or more output devices 155 (e.g., a speaker 160, a tactile output generator 170, and other output devices 180), one or more sensors 190 (e.g., an image sensor, a light sensor, a depth sensor, a tactile sensor, an orientation sensor, a proximity sensor, a temperature sensor, a position sensor, a motion sensor, a speed sensor, etc.), and optionally one or more peripheral devices 195 (e.g., a home appliance, a wearable device, etc.). In some embodiments, one or more of the input device 125, the output device 155, the sensor 190, and the peripheral device 195 are integrated with the display generation component 120 (e.g., in a head-mounted device or a handheld device).

[0041] When describing an XR experience, various terms are used to distinctly refer to several related but distinct environments that a user can sense and / or interact with (e.g., using inputs detected by the computer system 101 generating the XR experience, which inputs cause the computer system generating the XR experience to generate audio, visual, and / or haptic feedback corresponding to the various inputs provided to the computer system 101). The following is a subset of these terms: Physical Environment: The physical environment refers to the physical world that people can sense and / or interact with without the aid of electronic systems. A physical environment, such as a physical park, includes physical objects, such as physical trees, physical buildings, and physical people. People can directly sense and / or interact with the physical environment, such as through sight, touch, hearing, taste, and smell.

[0042] Extended Reality: In contrast, an extended reality (XR) environment refers to a fully or partially simulated environment that people sense and / or interact with via electronic systems. In XR, a subset of a person's physical movements, or representations thereof, is tracked, and in response, one or more characteristics of one or more virtual objects simulated in the XR environment are adjusted in a manner consistent with at least one law of physics. For example, an XR system can detect a person's head rotation and, in response, adjust the graphical content and sound field presented to the person in a manner similar to how such views and sounds change in a physical environment. In some cases (e.g., for accessibility reasons), adjustments to the characteristics of virtual objects in the XR environment can be made in response to representations of physical movement (e.g., voice commands). People can sense and / or interact with XR objects using any of their senses, including vision, hearing, touch, taste, and smell. For example, people can sense and / or interact with audio objects, which create a 3D or spatial audio environment that provides the perception of point audio sources in 3D space. As another example, audio objects can enable audio transparency, which selectively introduces ambient sounds from the physical environment with or without computer-generated audio. In some XR environments, people can sense and / or interact only with audio objects.

[0043] Examples of XR include virtual reality and mixed reality.

[0044] Virtual Reality: A virtual reality (VR) environment is a simulated environment designed to be based entirely on computer-generated sensory input to one or more senses. A VR environment includes multiple virtual objects that a person can sense and / or interact with. For example, trees, buildings, and computer-generated images representing human avatars are examples of virtual objects. A person can sense and / or interact with virtual objects in a VR environment through the simulation of their presence within the computer-generated environment and / or through the simulation of a subset of their physical movement within the computer-generated environment.

[0045] Mixed Reality: In contrast to VR environments, which are designed to be based entirely on computer-generated sensory input, mixed reality (MR) environments are simulated environments designed to incorporate sensory input from the physical environment, or representations thereof, in addition to computer-generated sensory input (e.g., virtual objects). On the virtuality continuum, a mixed reality environment is anything between, but not including, a fully physical environment at one end and a virtual reality environment at the other. In some MR environments, computer-generated sensory input can respond to changes in sensory input from the physical environment. Additionally, some electronic systems used to render MR environments can track position and / or orientation relative to the physical environment to enable virtual objects to interact with real objects (i.e., physical items from the physical environment, or representations thereof). For example, the system can account for motion so that virtual trees appear stationary relative to the physical ground.

[0046] Examples of mixed reality include augmented reality and augmented virtuality.

[0047] Augmented Reality: An augmented reality (AR) environment is a simulated environment in which one or more virtual objects are overlaid on top of a physical environment or a representation of a physical environment. For example, an electronic system used to present an AR environment may have a transparent or semi-transparent display through which a person can directly view the physical environment. The system can be configured to present virtual objects on the transparent or semi-transparent display, so that a person using the system perceives the virtual objects overlaid on the physical environment. Alternatively, the system may have an opaque display and one or more imaging sensors that capture images or video of the physical environment, which are representations of the physical environment. The system combines the images or video with the virtual objects and presents the combination on the opaque display. The person using the system indirectly views the physical environment via the images or video of the physical environment and perceives the virtual objects overlaid on the physical environment. As used herein, a video of the physical environment displayed on an opaque display is referred to as "pass-through video," meaning that the system uses one or more image sensors to capture images of the physical environment and uses those images when presenting the AR environment on the opaque display. Further alternatively, the system may have a projection system that projects virtual objects into a physical environment, such as as holograms or on a physical surface, so that a person using the system perceives the virtual objects superimposed on the physical environment. An augmented reality environment also refers to a simulated environment in which a representation of a physical environment is transformed by computer-generated sensory information. For example, in providing pass-through video, the system may transform one or more sensor images to apply a selected perspective (e.g., a viewpoint) that is different from the perspective captured by the imaging sensor. For another example, the representation of the physical environment may be transformed by graphically modifying (e.g., enlarging) a portion thereof so that the modified portion may be a representative, but not a true, version of the original captured image. For another example, the representation of the physical environment may be transformed by graphically eliminating or blurring a portion thereof.

[0048] Augmented Virtual: An augmented virtual (AV) environment is a simulated environment in which a virtual or computer-generated environment incorporates one or more sensory inputs from the physical environment. The sensory inputs can be representations of one or more characteristics of the physical environment. For example, an AV park may have virtual trees and virtual buildings, but human faces are realistically reproduced from images of physical people. In another example, virtual objects may adopt the shape or color of physical items imaged by one or more imaging sensors. In another example, virtual objects may adopt shadows that conform to the sun's position in the physical environment.

[0049] In an augmented reality, mixed reality, or virtual reality environment, a view of a three-dimensional environment is visible to a user. The view of the three-dimensional environment is typically visible to the user through a virtual viewport via one or more display generation components (e.g., a display or a pair of display modules that provide stereoscopic content to different eyes of the same user). The virtual viewport has viewport boundaries that define the extent of the three-dimensional environment visible to the user via the one or more display generation components. In some embodiments, the area defined by the viewport boundaries is smaller than the user's visual range in one or more dimensions (e.g., based on the user's visual range, the size, optical properties, or other physical characteristics of the one or more display generation components, and / or the position and / or orientation of the one or more display generation components relative to the user's eyes). In some embodiments, the area defined by the viewport boundaries is larger than the user's visual range in one or more dimensions (e.g., based on the user's visual range, the size, optical properties, or other physical characteristics of the one or more display generation components, and / or the position and / or orientation of the one or more display generation components relative to the user's eyes). The viewport and viewport boundaries typically move with movement of the one or more display generation components (e.g., with the user's head for a head-mounted device, or with the user's hand for a handheld device such as a tablet or smartphone). The user's viewpoint determines what is visible in the viewport. The viewpoint typically specifies a position and orientation relative to the 3D environment, and as the viewpoint moves, the view of the 3D environment also moves in the viewport. For head-mounted devices, the viewpoint is typically based on the position and orientation of the user's head, face, and / or eyes to provide a perceptually accurate view of the 3D environment that provides an immersive experience while the user is using the head-mounted device. For handheld or fixed devices, the viewpoint moves as the handheld or fixed device moves and / or as the user's positioning relative to the handheld or fixed device changes (e.g., as the user moves toward, away from, up, down, right, and / or left). For devices that include display generation components with virtual pass-through, portions of the physical environment that are visible (e.g., displayed and / or projected) via the one or more display generation components are based on the field of view of one or more cameras in communication with the display generation components, which typically move with movement of the display generation components (e.g., with movement of the user's head for a head-mounted device, or with movement of the user's hands for a handheld device such as a tablet or smartphone) as the user's viewpoint moves with movement of the field of view of the one or more cameras (and the appearance of one or more virtual objects displayed via the one or more display generation components is updated based on the user's viewpoint (e.g., the display positioning and pose of the virtual objects are updated based on movement of the user's viewpoint)).For display generating components with optical transmittance, portions of the physical environment visible via one or more display generating components (e.g., optically visible through one or more partially or fully transparent portions of the display generating components) are based on the user's field of view through the partially or fully transparent portions of the display generating components (e.g., moves with movement of the user's head for a head-mounted device, or moves with movement of the user's hands for a handheld device such as a tablet or smartphone), because the user's viewpoint moves as the user moves through the field of view of the partially or fully transparent portions of the display generating components (and the appearance of one or more virtual objects is updated based on the user's viewpoint).

[0050] In some embodiments, the representation of the physical environment (e.g., displayed via virtual pass-through or optical pass-through) may be partially or completely obscured by the virtual environment. In some embodiments, the amount of the virtual environment displayed (e.g., the amount of the physical environment that is not displayed) is based on the immersion level of the virtual environment (e.g., relative to the representation of the physical environment). For example, increasing the immersion level optionally causes more of the virtual environment to be displayed, replacing and / or obscuring more of the physical environment, and decreasing the immersion level optionally causes less of the virtual environment to be displayed, thereby revealing portions of the physical environment that were previously not displayed and / or obscured. In some embodiments, at a particular immersion level, one or more first background objects (e.g., in the representation of the physical environment) are visually de-emphasized (e.g., dimmed, blurred, and / or displayed with increased transparency) more than one or more second background objects, and one or more third background objects cease to be displayed. In some embodiments, the immersion level includes an associated degree to which virtual content displayed by the computer system (e.g., a virtual environment and / or virtual content) obscures background content (e.g., content other than the virtual environment and / or virtual content) surrounding / behind the virtual environment, optionally including the number of items of background content displayed and / or the displayed visual characteristics of the background content (e.g., color, contrast, and / or opacity), the angular range of the virtual content displayed via the display generation component (e.g., 60 degrees for content displayed at low immersion, 120 degrees for content displayed at medium immersion, or 180 degrees for content displayed at high immersion), and / or the proportion of the field of view displayed via the display generation component that is occupied by the virtual content (e.g., 33% of the field of view occupied by the virtual content at low immersion, 66% of the field of view occupied by the virtual content at medium immersion, or 100% of the field of view occupied by the virtual content at high immersion). In some embodiments, the background content is included in the background on which the virtual content is displayed (e.g., background content in a representation of the physical environment). In some embodiments, the background content includes a user interface (e.g., a user interface corresponding to an application generated by a computer system), virtual objects that are not associated with or included in the virtual environment and / or virtual content (e.g., files generated by a computer system or representations of other users, etc.), and / or real objects (e.g., see-through objects representing real objects in the physical environment surrounding the user, which are visible so that they are displayed via the display generation component and / or are visible via transparent or translucent components of the display generation component because the computer system does not block / impede their visibility through the display generation component). In some embodiments, at a low immersion level (e.g., a first immersion level), the background, virtual and / or real objects are displayed in an unobstructed manner. For example, a virtual environment with a low immersion level is optionally displayed simultaneously with the background content, which is optionally displayed at full brightness, color and / or translucency.In some embodiments, at a higher immersion level (e.g., a second immersion level higher than the first immersion level), background, virtual, and / or real objects are displayed in an obscured manner (e.g., dimmed, blurred, or removed from the display). For example, a corresponding virtual environment with a high immersion level is displayed without simultaneously displaying background content (e.g., in full-screen or fully immersive mode). In another example, a virtual environment displayed at a medium immersion level is displayed simultaneously with background content that is dimmed, blurred, or otherwise de-emphasized. In some embodiments, the visual characteristics of background objects vary between background objects. For example, at a particular immersion level, one or more first background objects are visually de-emphasized (e.g., dimmed, blurred, and / or displayed with increased transparency) more than one or more second background objects, and one or more third background objects cease to be displayed. In some embodiments, a null or zero immersion level corresponds to the virtual environment ceasing to be displayed, and instead displaying a representation of the physical environment (optionally with one or more virtual objects, such as applications, windows, or virtual three-dimensional objects), without the representation of the physical environment being obscured by the virtual environment. Adjusting the immersion level using physical input elements provides a fast and efficient method of adjusting immersion, which enhances the operability of the computer system and makes the user-device interface more efficient.

[0051] Viewpoint-locked virtual objects: When a computer system displays a virtual object at the same position and / or location in a user's viewpoint, even if the user's viewpoint shifts (e.g., changes), the virtual object is viewpoint-locked. In embodiments where the computer system is a head-mounted device, the user's viewpoint is locked to the forward direction of the user's head (e.g., when the user is looking straight ahead, the user's viewpoint is at least a portion of the user's field of view); thus, without moving the user's head, the user's viewpoint remains fixed even when the user's gaze shifts. In embodiments where the computer system has a display generation component (e.g., a display screen) that is repositionable relative to the user's head, the user's viewpoint is the augmented reality view presented to the user on the computer system's display generation component. For example, a viewpoint-locked virtual object that is displayed in the upper left corner of the user's viewpoint when the user's viewpoint is in a first orientation (e.g., the user's head is facing north) continues to be displayed in the upper left corner of the user's viewpoint even if the user's viewpoint changes to a second orientation (e.g., the user's head is facing west). In other words, the position and / or location of the viewpoint-locked virtual object displayed in the user's viewpoint is independent of the user's position and / or orientation in the physical environment. In embodiments where the computer system is a head-mounted device, the user's viewpoint is locked to the orientation of the user's head, such that the virtual object is also referred to as a "head-locked virtual object."

[0052] Environment-locked visual objects: A virtual object is environment-locked (alternatively, "world-locked") when a computer system displays it at a location and / or position in a user's viewpoint that is based on (e.g., selected with reference to and / or anchored to) a location and / or object in a three-dimensional environment (e.g., a physical environment or a virtual environment). As the user's viewpoint moves, the location and / or objects in the environment change relative to the user's viewpoint, which causes the environment-locked virtual object to be displayed at a different location and / or position in the user's viewpoint. For example, an environment-locked virtual object locked to a tree immediately in front of the user is displayed at the center of the user's viewpoint. When the user's viewpoint shifts to the right (e.g., the user's head turns to the right) so that the tree is now to the left of center in the user's viewpoint (e.g., the tree's position in the user's viewpoint shifts), the environment-locked virtual object locked to the tree is displayed to the left of center in the user's viewpoint. In other words, the position and / or location at which an environment-locked virtual object is displayed in the user's viewpoint depends on the location and / or location of the object in the environment to which the virtual object is locked. In some embodiments, the computer system uses a stationary reference frame (e.g., a coordinate system anchored to fixed locations and / or objects in the physical environment) to determine the location at which an environment-locked virtual object is displayed in the user's viewpoint. An environment-locked virtual object can be locked to a stationary portion of the environment (e.g., a floor, wall, table, or other stationary object), or can be locked to a movable portion of the environment (e.g., a vehicle, an animal, a person, or even a representation of a part of the user's body that moves independently of the user's viewpoint, such as a hand, wrist, arm, or foot) so that the virtual object moves as the viewpoint or that portion of the environment moves to maintain a fixed relationship between the virtual object and that portion of the environment.

[0053] In some embodiments, an environment-locked or viewpoint-locked virtual object exhibits lazy following behavior, which reduces or delays the movement of the environment-locked or viewpoint-locked virtual object relative to the movement of a reference point that the virtual object is following. In some embodiments, when lazy following behavior is exhibited, the computer system intentionally delays the movement of the virtual object upon detecting movement of a reference point that the virtual object is following (e.g., a portion of the environment, a viewpoint, or a point fixed relative to the viewpoint, such as a point between 5 cm and 300 cm from the viewpoint). For example, when the reference point (e.g., a portion of the environment or a viewpoint) moves at a first speed, the virtual object is moved by the device to remain locked to the reference point, but at a second speed that is slower than the first speed (e.g., until the reference point stops moving or slows down, at which point the virtual object begins to catch up with the reference point). In some embodiments, when the virtual object exhibits lazy following behavior, the device ignores small amounts of movement of the reference point (e.g., ignoring movements of the reference point below a threshold amount of movement, such as movement of 0 to 5 degrees or movement of 0 to 50 cm). For example, when a reference point (e.g., a portion or viewpoint of an environment to which a virtual object is locked) moves a first amount, the distance between the reference point and the virtual object increases (e.g., because the virtual object is being displayed so as to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and when the reference point (e.g., the portion or viewpoint of the environment to which the virtual object is locked) moves a second amount greater than the first amount, the distance between the reference point and the virtual object first increases (e.g., because the virtual object is being displayed so as to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and then decreases when the amount of movement of the reference point increases above a threshold (e.g., a “lazy follow” threshold) because the virtual object is moved by the computer system to maintain a fixed or substantially fixed position relative to the reference point. In some embodiments, maintaining a substantially fixed position of the virtual object relative to the reference point includes displaying the virtual object within a threshold distance (e.g., 1 cm, 2 cm, 3 cm, 5 cm, 15 cm, 20 cm, 50 cm) of the reference point in one or more dimensions (e.g., up / down, left / right, and / or forward / backward relative to the position of the reference point).

[0054] In some embodiments, spatial media includes spatial visual media and / or spatial audio. In some embodiments, spatial capture is the capture of spatial media. In some embodiments, spatial visual media (also referred to as stereoscopic media) (e.g., spatial images and / or spatial video) is media that includes two different images or sets of images representing two perspectives with the same or overlapping fields of view for concurrent display. A first image representing a first perspective is presented to a viewer's first eye, and a second image representing a second perspective different from the first perspective is simultaneously presented to the viewer's second eye. The first and second images have the same or overlapping fields of view. In some embodiments, a computer system displays the first image via a first display positioned for viewing by the viewer's first eye and simultaneously displays the second image via a second display different from the first display and positioned for viewing by the viewer's second eye. In some embodiments, when viewed together, the first and second images create a depth effect and provide the viewer with a depth perception of the content of the images. In some embodiments, a first video representing the first perspective is presented to the viewer's first eye, and a second video representing the second perspective different from the first perspective is simultaneously presented to the viewer's second eye. The first video and the second video have the same or overlapping fields of view. In some embodiments, when viewed together, the first video and the second video create a depth effect and provide the viewer with a depth perception of the content of the videos. In some embodiments, a spatial audio experience in headphones is generated by manipulating the sounds in two audio channels (e.g., left and right) of the headphones so that they resemble directional sounds arriving at the ear canal. For example, the headphones can reproduce a spatial audio signal that simulates the soundscape surrounding a listener (also referred to as a user). Effective spatial sound reproduction can present sounds so that the listener perceives the sounds as coming from locations within the soundscape outside the listener's head, just as the listener would experience the sounds if they were encountering them in the real world.

[0055] The geometry of a listener's ear, and in particular, the outer ear (pinna), has a significant impact on the sound that reaches the listener's eardrum from a sound source. A spatial audio sound experience can be achieved by taking into account the influence of the listener's pinna, head, and / or torso on the sound entering the listener's ear canal. The geometry of the user's ear is optionally determined using a 3D scanning device that generates a 3D model of at least a portion of the visible portion of the user's ear. This geometry is optionally used to generate filters used to produce the spatial audio experience. In some embodiments, spatial audio is audio that has been filtered so that a listener perceives the audio as coming from one or more directions and / or positions in three-dimensional space (e.g., from above, below, and / or in front of the listener).

[0056] An example of such a filter is a head-related transfer function (HRTF) filter. These filters are used to provide an effect similar to how the human ear, head, and torso filter sound. When the geometry of a listener's ear is known, a personalized filter (e.g., a personalized HRTF filter) can be generated to make the sound experienced by the listener through headphones (e.g., in-ear headphones, on-ear headphones, and / or circumaural headphones) more realistic. In some embodiments, two filters are generated—one for each ear—so that each ear of the listener has a corresponding personalized filter (e.g., a personalized HRTF filter), as listeners may have different ear geometries.

[0057] In some embodiments, the HRTF filter includes some (or all) of the acoustic information needed to describe how sound reflects or diffracts around the listener's head before entering the listener's auditory system. In some embodiments, the personalized HRTF filter can be selected from a database of previously determined HRTFs for users with similar anatomical characteristics. In some embodiments, the personalized HRTF filter can be generated by digital modeling based on the geometry of the listener's ear. One or more processors of the computer system optionally apply the personalized HRTF filter for the listener to the audio input signal to generate a spatial input signal for playback by headphones connected (e.g., wirelessly or wired) to the computer system.

[0058] Hardware: Many different types of electronic systems enable people to sense and / or interact with various XR environments. Examples include head-mounted systems, projection-based systems, heads-up displays (HUDs), vehicle windshields with integrated display capabilities, windows with integrated display capabilities, displays formed as lenses designed to be placed on a person's eyes (e.g., similar to contact lenses), headphones / earpieces, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablet devices, and desktop / laptop computers. A head-mounted system may include speakers and / or other audio output devices integrated into the head-mounted system for providing audio output. A head-mounted system may have one or more speakers and an integrated opaque display. Alternatively, a head-mounted system may be configured to accept an external opaque display (e.g., a smartphone). A head-mounted system may incorporate one or more imaging sensors for capturing images or video of the physical environment and / or one or more microphones for capturing audio of the physical environment. Instead of an opaque display, a head-mounted system may have a transparent or translucent display. A transparent or translucent display can have a medium through which light representing an image is directed to a person's eyes. The display can utilize digital light projection, OLED, LED, uLED, liquid crystal on silicon, laser scanning light sources, or any combination of these technologies. The medium can be an optical waveguide, a holographic medium, an optical combiner, an optical reflector, or any combination thereof. In one embodiment, the transparent or translucent display can be configured to selectively become opaque. Projection-based systems can employ retinal projection technology that projects graphic images onto a person's retina. The projection system can also be configured to project virtual objects into a physical environment, such as as a hologram or on a physical surface. In some embodiments, the controller 110 is configured to manage and coordinate the user's XR experience. In some embodiments, the controller 110 includes a suitable combination of software, firmware, and / or hardware. Figure 2Controller 110 is described in more detail. In some embodiments, controller 110 is a computing device that is located locally or remotely relative to scene 105 (e.g., a physical environment). For example, controller 110 is a local server located within scene 105. In another example, controller 110 is a remote server (e.g., a cloud server, a central server, etc.) located outside of scene 105. In some embodiments, controller 110 is communicatively coupled to display generation component 120 (e.g., an HMD, a display, a projector, a touch screen, etc.) via one or more wired or wireless communication channels 144 (e.g., Bluetooth, IEEE 802.11x, IEEE 802.16x, IEEE 802.3x, etc.). In another example, the controller 110 is included within a housing (e.g., a physical housing) of the display generating component 120 (e.g., an HMD or a portable electronic device including a display and one or more processors, etc.), one or more input devices of the input devices 125, one or more output devices of the output devices 155, one or more sensors of the sensors 190, and / or one or more peripheral devices 195, or shares the same physical housing or support structure with one or more of the above devices.

[0059] In some embodiments, the display generation component 120 is configured to provide an XR experience (e.g., at least the visual component of the XR experience) to the user. In some embodiments, the display generation component 120 includes a suitable combination of software, firmware, and / or hardware. Figure 3 Display generation component 120 is described in further detail. In some embodiments, the functionality of controller 110 is provided by and / or combined with display generation component 120.

[0060] According to some embodiments, display generation component 120 provides an XR experience to the user while the user is virtually and / or physically present within scene 105 .

[0061] In some embodiments, the display generation component is worn on a portion of the user's body (e.g., on their head, on their hands, etc.). Thus, the display generation component 120 includes one or more XR displays provided for displaying XR content. For example, in various embodiments, the display generation component 120 surrounds the user's field of view. In some embodiments, the display generation component 120 is a handheld device (such as a smartphone or tablet) configured to present XR content, and the user holds the device with a display facing the user's field of view and a camera facing the scene 105. In some embodiments, the handheld device is optionally placed within a housing worn on the user's head. In some embodiments, the handheld device is optionally placed on a support (e.g., a tripod) in front of the user. In some embodiments, the display generation component 120 is an XR room, housing, or room configured to present XR content, wherein the user does not wear or hold the display generation component 120. Many user interfaces described with reference to one type of hardware for displaying XR content (e.g., a handheld device or a device on a tripod) can be implemented on another type of hardware for displaying XR content (e.g., an HMD or other wearable computing device). For example, a user interface that illustrates interactions with XR content triggered based on interactions occurring in the space in front of a handheld device or a tripod-mounted device can similarly be implemented using an HMD, where the interactions occur in the space in front of the HMD and the responses to the XR content are displayed via the HMD. Similarly, a user interface that illustrates interactions with XR content triggered based on movement of a handheld device or a tripod-mounted device relative to a physical environment (e.g., scene 105 or a part of a user's body (e.g., the user's eyes, head, or hands)) can similarly be implemented using an HMD, where the movement is caused by movement of the HMD relative to the physical environment (e.g., scene 105 or a part of a user's body (e.g., the user's eyes, head, or hands)).

[0062] Despite Figure 1A Relevant features of the operating environment 100 are shown in FIG, but those skilled in the art will recognize from this disclosure that various other features are not illustrated for the sake of brevity and so as not to obscure more relevant aspects of the example embodiments disclosed herein.

[0063] Figures 1A to 1PVarious examples of computer systems for performing the methods and providing audio, visual, and / or tactile feedback as part of the user interfaces described herein are illustrated. In some embodiments, the computer system includes one or more display generation components (e.g., first and second display assemblies 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a and 11.1.1-104b) for displaying virtual elements and / or representations of the physical environment to a user of the computer system, the virtual elements and / or representations of the physical environment optionally being generated based on detected events and / or user input detected by the computer system. The user interface generated by the computer system is optionally corrected by one or more corrective lenses 11.3.2-216 to make it easier for users who would otherwise use glasses or contact lenses to correct their vision to view the user interface, the one or more corrective lenses optionally being removably attached to one or more of the optical modules. While many of the user interfaces shown herein show a single view of the user interface, a user interface in an HMD is optionally displayed using two optical modules (e.g., a first display component 1-120a and a second display component 1-120b and / or a first optical module 11.1.1-104a and a second optical module 11.1.1-104b), one optical module for the user's right eye and a different optical module for the user's left eye, with slightly different images presented to the two different eyes to create the illusion of stereoscopic depth, the single view of the user interface typically being a right eye view or a left eye view, with the depth effect explained in the text or using other diagrams or views. In some embodiments, a computer system includes one or more external displays (e.g., a display component 1-108) for displaying status information of the computer system to a user of the computer system (when the computer system is not being worn) and / or to other people near the computer system, the status information being optionally generated based on detected events and / or user input detected by the computer system. In some embodiments, the computer system includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback, which is optionally generated based on detected events and / or user input detected by the computer system. In some embodiments, the computer system includes one or more input devices for detecting input, such as one or more sensors for detecting information about the physical environment of the device (e.g., one or more sensors in sensor components 1-356, and / or Figure 1I ), which information can be used (optionally in conjunction with one or more luminaires, such as Figure 1IIn some embodiments, the computer system includes one or more input devices for detecting input, such as one or more sensors for detecting hand positioning and / or movement (e.g., sensor assembly 1-356 and / or sensor assembly 1-357). Figure 1I One or more sensors in ), which can be used (optionally in combination with one or more illuminators, such as Figure 1I In some embodiments, the computer system includes one or more input devices for detecting input, such as one or more sensors for detecting eye movement (e.g., Figure 1I Eye tracking and gaze tracking sensors in the Figure 1O11.3.2-110) determine attention or gaze location and / or gaze movement, which can optionally be used to detect gaze-only input based on gaze movement and / or dwell. Combinations of the various sensors described above can be used to determine user facial expressions and / or hand movements for use in generating an avatar or representation of the user, such as an anthropomorphic avatar or representation for use in a real-time communication session, where the avatar has facial expressions, hand movements, and / or body movements that are based on or similar to the detected facial expressions, hand movements, and / or body movements of the user of the device. Gaze and / or attention information is optionally combined with hand tracking information to determine interaction between a user and one or more user interfaces based on direct and / or indirect input, such as air gestures or input using one or more hardware input devices, such as one or more buttons (e.g., first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328), knobs (e.g., first button 1-128, button 11.1.1-114, and / or dial or button 1-328), a digital crown (e.g., a pressable and twistable or rotatable first button 1-128, button 11.1.1-114, and / or dial or button 1-328), a touchpad, a touch screen, a keyboard, a mouse, and / or other input devices. One or more buttons (e.g., first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328) are optionally used to perform system operations, such as re-centering content in a three-dimensional environment visible to a user of the device, displaying a primary user interface for launching an application, starting a real-time communication session, or initiating display of a virtual three-dimensional background. A knob or digital crown (e.g., a pressable and twistable or rotatable first button 1-128, button 11.1.1-114, and / or dial or button 1-328) is optionally rotatable to adjust parameters of the visual content, such as the immersion level of the virtual three-dimensional environment (e.g., the extent to which the virtual content occupies the user's viewport in the three-dimensional environment) or other parameters associated with the three-dimensional environment and virtual content displayed via the optical modules (e.g., first display component 1-120a and second display component 1-120b and / or first optical module 11.1.1-104a and second optical module 11.1.1-104b).

[0064] Figure 1BFront, top, and perspective views of an example head-mountable display (HMD) device 1-100 configured to be worn by a user and provide a virtual and altered / mixed reality (VR / AR) experience are shown. The HMD 1-100 may include a display unit 1-102 or assembly, an electronic strap assembly 1-104 connected to and extending from the display unit 1-102, and a strap assembly 1-106 secured to the electronic strap assembly 1-104 at either end. The electronic strap assembly 1-104 and the strap 1-106 may be part of a retaining assembly configured to wrap around a user's head to hold the display unit 1-102 against the user's face.

[0065] In at least one example, the strap assembly 1-106 can include a first strap 1-116 configured to wrap around the back of a user's head and a second strap 1-117 configured to extend over the top of the user's head. As shown, the second strap can extend between the first electronic strip 1-105a and the second electronic strip 1-105b of the electronic strip assembly 1-104. The strap assembly 1-104 and the strap assembly 1-106 can be part of a securing mechanism that extends rearward from the display unit 1-102 and is configured to hold the display unit 1-102 against the user's face.

[0066] In at least one example, the securing mechanism includes a first electronic strip 1-105a including a first proximal end 1-134 coupled to the display unit 1-102 (e.g., the housing 1-150 of the display unit 1-102) and a first distal end 1-136 opposite the first proximal end 1-134. The securing mechanism may also include a second electronic strip 1-105b including a second proximal end 1-138 coupled to the housing 1-150 of the display unit 1-102 and a second distal end 1-140 opposite the second proximal end 1-138. The securing mechanism may also include a first band 1-116 and a second band 1-117, the first band including a first end 1-142 coupled to the first distal end 1-136 and a second end 1-144 coupled to the second distal end 1-140, with the second band extending between the first electronic strip 1-105a and the second electronic strip 1-105b. The strips 1-105a-1-105b and the strip 1-116 may be coupled via a connecting mechanism or assembly 1-114. In at least one example, the second strip 1-117 includes a first end 1-146 coupled to the first electronic strip 1-105a between a first proximal end 1-134 and a first distal end 1-136 and a second end 1-148 coupled to the second electronic strip 1-105b between a second proximal end 1-138 and a second distal end 1-140.

[0067] In at least one example, the first and second electronic strips 1-105a-1-105b comprise plastic, metal, or other structural material that forms the shape of substantially rigid strips 1-105a-1-105b. In at least one example, the first and second bands 1-116, 1-117 are formed of a resilient, flexible material, including woven textiles, rubber, and the like. The first and second bands 1-116, 1-117 can be flexible to conform to the shape of a user's head when the HMD 1-100 is worn.

[0068] In at least one example, one or more of the first and second electronic strips 1-105a to 1-105b can define an interior strip volume and include one or more electronic components disposed within the interior strip volume.

In one example, the electronic component 1-112 may include a computing component, such as a processor.

[0069] In at least one example, the housing 1-150 defines a first front opening 1-152. Figure 1B The housing 1-150 is marked with a dashed line 1-152 because the display assembly 1-108 is configured to obscure the first opening 1-152 from view when the HMD 1-100 is assembled. The housing 1-150 may also define a rearwardly disposed second opening 1-154. The housing 1-150 further defines an interior volume between the first opening 1-152 and the second opening 1-154. In at least one example, the HMD 1-100 includes a display assembly 1-108, which may include a front cover disposed in or across the front opening to obscure the front opening 1-152 and a display screen (shown in other figures). In at least one example, the display screen of the display assembly 1-108, and the display assembly 1-108 generally, has a curvature configured to follow the curvature of the user's face. The display screen of the display assembly 1-108 may be curved as shown to complement the user's facial features and the overall curvature from one side of the face to the other, such as from left to right and / or from top to bottom, with the display unit 1-102 being pressed.

[0070] In at least one example, the housing 1-150 may define a first aperture 1-126 between the first opening 1-152 and the second opening 1-154, and a second aperture 1-130 between the first opening 1-152 and the second opening 1-154. The HMD 1-100 may also include a first button 1-126 disposed in the first aperture 1-128, and a second button 1-132 disposed in the second aperture 1-130. The first button 1-128 and the second button 1-132 are capable of being pressed through the respective apertures 1-126, 1-130. In at least one example, the first button 1-126 and / or the second button 1-132 may be a twistable dial and a depressible button. In at least one example, the first button 1-128 is a depressible and twistable dial button, and the second button 1-132 is a depressible button.

[0071] Figure 1C A rear perspective view of an HMD 1-100 is shown. The HMD 1-100 may include a light seal 1-110 extending rearwardly from a housing 1-150 of a display assembly 1-108 around the perimeter of the housing 1-150, as shown. The light seal 1-110 may be configured to extend from the housing 1-150 to the user's face, surrounding the user's eyes, to block external light from being visible. In one example, the HMD 1-100 may include a first display assembly 1-120a and a second display assembly 1-120b disposed at or within a rearward-facing second opening 1-154 defined by the housing 1-150 and / or disposed within the interior volume of the housing 1-150 and configured to project light through the second opening 1-154. In at least one example, each display assembly 1-120a to 1-120b may include a respective display screen 1-122a, 1-122b configured to project light in a rearward direction through the second opening 1-154 toward the user's eyes.

[0074] Figure 1D An exploded view of an example of an HMD 1-200 including its various parts or components is shown, which are separated according to the modularity and selective coupling of these components. For example, the HMD 1-200 may include a strap 1-216 that can be selectively coupled to a first electronic strip 1-205a and a second electronic strip 1-205b. The first fixed strap 1-205a may include a first electronic component 1-212a, and the second fixed strap 1-205b may include a second electronic component 1-212b.

[0084] Figure 1G An exploded perspective view of the front cover assembly 3-100 of the HMD device described herein is illustrated, for example Figure 1G The front cover assembly 3-1 of the illustrated HMD 3-100 or any other HMD device shown and described herein. Figure 1G The illustrated front cover assembly 3-100 may include a transparent or translucent cover 3-102, a shield 3-104 (or "cover"), an adhesive layer 3-106, a display assembly 3-108 including a lenticular lens panel or array 3-110, and a structural trim 3-112. The adhesive layer 3-106 may secure the shield 3-104 and / or the transparent cover 3-102 to the display assembly 3-108 and / or the trim 3-112. The trim 3-112 may secure the various components of the front cover assembly 3-100 to the frame or base of the HMD device.

[0085] In at least one example, Figure 1G As shown, the transparent cover 3-102, the shield 3-104, and the display assembly 3-108 including the lenticular lens array 3-110 can be curved to accommodate the curvature of the user's face. The transparent cover 3-102 and the shield 3-104 can be curved in two or three dimensions, for example, vertically in the Z direction within and outside the ZX plane and horizontally in the X direction within and outside the ZX plane. In at least one example, the display assembly 3-108 can include the lenticular lens array 3-110 and a display panel having pixels that are configured to project light through the shield 3-104 and the transparent cover 3-102. The display assembly 3-108 can be curved in at least one direction (e.g., the horizontal direction) to accommodate the curvature of the user's face from one side of the face (e.g., the left side) to the other side (e.g., the right side). In at least one example, each layer or component of the display assembly 3-108 (which will be shown in subsequent figures and described in more detail, but which may include a lenticular lens array 3-110 and a display layer) may be curved similarly or concentrically in the horizontal direction to accommodate the curvature of the user's face.

[0086] In at least one example, the shield 3-104 may include a transparent or translucent material through which the display assembly 3-108 projects light. In one example, the shield 3-104 may include one or more opaque portions, such as an opaque ink-printed portion or other opaque film portion on the back of the shield 3-104. When the HMD device is worn, the back surface may be the surface of the shield 3-104 that faces the user's eyes. In at least one example, the opaque portion may be on the front surface of the shield 3-104, opposite the back surface. In at least one example, the one or more opaque portions of the shield 3-104 may include a peripheral portion that visually conceals any components surrounding the outer perimeter of the display screen of the display assembly 3-108. In this manner, the opaque portion of the shield conceals any other components of the HMD device that would otherwise be visible through the transparent or translucent cover 3-102 and / or shield 3-104, including electronic components, structural components, etc.

[0087] In at least one example, the shield 3-104 may define one or more apertured transparent portions 3-120 through which sensors may transmit and receive signals. In one example, the portion 3-120 is an aperture through which a sensor may extend or transmit and receive signals. In one example, the portion 3-120 is a transparent portion, or a portion that is more transparent than surrounding translucent or opaque portions of the shield, through which sensors may transmit and receive signals through the shield and through the transparent cover 3-102. In one example, the sensor may include a camera, an IR sensor, a LUX sensor, or any other visual or non-visual environmental sensor of the HMD device.

The HMD device 6-100 may include a sensor array or system 6-102 including one or more sensors, cameras, projectors, etc. mounted to one or more components of the HMD 6-100. In at least one example, the sensor system 6-102 may include a bracket 1-338 to which one or more sensors of the sensor system 6-102 may be secured / fastened.

[0090] Figure 1I A portion of an HMD device 6-100 is shown including a front transparent cover 6-104 and a sensor system 6-102. The sensor system 6-102 may include a plurality of different sensors, emitters, receivers, including cameras, IR sensors, projectors, etc. The transparent cover 6-104 is shown in front of the sensor system 6-102 to illustrate the relative positioning of the various sensors and emitters and the orientation of each sensor / emitter of the system 6-102. As referred to herein, "beside," "side," "lateral," "horizontal," and other similar terms refer to the positions of the sensors and emitters as indicated by the front transparent cover 6-104. Figure 1J The orientation or direction is indicated by the X-axis shown. Terms such as "vertical", "upward", "downward" and similar terms refer to the direction indicated by the X-axis. Figure 1J The orientation or direction is indicated by the Z-axis shown. Terms such as "frontward," "rearward," "forward," "backward," and similar terms refer to the direction of the vehicle as indicated by the Z-axis. Figure 1J The orientation or direction indicated by the Y-axis is shown.

[0091] In at least one example, a transparent cover 6-104 may define a front exterior surface of the HMD device 6-100, and a sensor system 6-102, including various sensors and components thereof, may be disposed in the Y axis / direction behind the cover 6-104. The cover 6-104 may be transparent or translucent to allow light to pass through the cover 6-104, including both light detected by the sensor system 6-102 and light emitted thereby.

Furthermore, as will be shown in greater detail below with reference to other figures, the various sensors, transmitters, and other components of the sensor system 6-102 may be coupled to the HMD device 6-100. Figure 1I Various structural frame members, brackets, etc. are not shown in the figure. For the sake of clarity, Figure 1I Components of the sensor system 6-102 are shown unattached and unelectrically coupled to other components.

[0093] In at least one example, the device may include one or more controllers having processors configured to execute instructions stored on a memory component electrically coupled to the processors. The instructions may include or cause the processors to execute one or more algorithms for self-correcting the angles and positions of the various cameras described herein over time as the initial position, angle, or orientation of the camera is bumped or deformed due to an accidental drop event or other event.

[0094] In at least one example, the sensor system 6-102 may include one or more scene cameras 6-106. The system 6-102 may include two scene cameras 6-102, one positioned on either side of the nose bridge or arch of the HMD device 6-100, such that each of the two cameras 6-106 roughly corresponds to the positioning of the user's left and right eyes behind the cover 6-103. In at least one example, the scene cameras 6-106 are generally oriented forward in the Y direction to capture images in front of the user during use of the HMD 6-100. In at least one example, the scene cameras are color cameras and provide images and content for MR video pass-through to a display screen facing the user's eyes when the HMD device 6-100 is in use. The scene cameras 6-106 may also be used for environment and object reconstruction.

[0095] In at least one example, the sensor system 6-102 may include a first depth sensor 6-108 that points generally forward in the Y direction. In at least one example, the first depth sensor 6-108 may be used for environment and object reconstruction and hand and body tracking of a user. In at least one example, the sensor system 6-102 may include a second depth sensor 6-110 that is centrally located along the width of the HMD device 6-100 (e.g., along the X axis). For example, the second depth sensor 6-110 may be located above a central nose bridge or on a fitting structure that is located above the nose of the user when the HMD 6-100 is worn. In at least one example, the second depth sensor 6-110 may be used for environment and object reconstruction and hand and body tracking. In at least one example, the second depth sensor may include a LIDAR sensor.

[0096] In at least one example, the sensor system 6-102 may include a depth projector 6-112 that faces generally forward to project electromagnetic waves (e.g., in a predetermined pattern of light dots) into or within the field of view of the user and / or scene camera 6-106, or into or within a field of view that includes and extends beyond the field of view of the user and / or scene camera 6-106. In at least one example, the depth projector may be capable of projecting electromagnetic waves of light in a pattern of light dots that reflect off an object and return to the depth sensors described above, including the depth sensors 6-108 and 6-110. In at least one example, the depth projector 6-112 may be used for environment and object reconstruction and hand and body tracking.

[0097] In at least one example, the sensor system 6-102 may include downward-facing cameras 6-114 whose fields of view are generally directed downward on the Z-axis relative to the HMD device 6-100. In at least one example, the downward-facing cameras 6-114 may be disposed on the left and right sides of the HMD device 6-100 as shown and used for hand and body tracking, headset tracking, and facial avatar detection and creation for displaying a user avatar on a forward-facing display screen of the HMD device 6-100 as described elsewhere herein. For example, the downward-facing cameras 6-114 may be used to capture facial expressions and movements of a user's face, including cheeks, mouth, and chin, beneath the HMD device 6-100.

[0098] In at least one example, the sensor system 6-102 may include a jaw camera 6-116. In at least one example, the jaw cameras 6-116 may be positioned on the left and right sides of the HMD device 6-100 as shown and used for hand and body tracking, headset tracking, and facial avatar detection and creation for displaying a user avatar on a front-facing display screen of the HMD device 6-100 as described elsewhere herein. For example, the jaw camera 6-116 may be used to capture facial expressions and movements of a user's face (including the user's jaw, cheeks, mouth, and chin) beneath the HMD device 6-100. For hand and body tracking, headset tracking, and facial avatar detection and creation, the jaw camera 6-116 may be positioned on the left and right sides of the HMD device 6-100 as shown and used for hand and body tracking, headset tracking, and facial avatar detection and creation for displaying a user avatar on a front-facing display screen of the HMD device 6-100 as described elsewhere herein. In at least one example, the sensor system 6-102 may include a side camera 6-118. The side camera 6-118 may be oriented to capture left and right side views in an X-axis or direction relative to the HMD device 6-100.

[0099] In at least one example, the sensor system 6-102 may include a plurality of eye tracking and gaze tracking sensors for determining the identity, status, and gaze direction of a user's eyes during and / or prior to use. In at least one example, the eye / gaze tracking sensors may include nose-eye cameras 6-120 that are positioned on either side of the user's nose and adjacent to the user's nose when the HMD device 6-100 is worn. The eye / gaze sensors may also include bottom eye cameras 6-122 positioned below the respective user's eyes for capturing images of the eyes for use in facial avatar detection and creation, gaze tracking, and iris identification functionality.

[0100] In at least one example, the sensor system 6-102 may include an infrared illuminator 6-124 that points outward from the HMD device 6-100 to illuminate the external environment and any objects therein with IR light for IR detection using one or more IR sensors of the sensor system 6-102. In at least one example, the sensor system 6-102 may include a flicker sensor 6-126 and an ambient light sensor 6-128. In at least one example, the flicker sensor 6-126 may detect the refresh rate of overhead light to avoid display flicker. In one example, the infrared illuminator 6-124 may include a light emitting diode and may be particularly useful in low-light environments for illuminating a user's hands and other objects in low light for detection by the infrared sensors of the sensor system 6-102.

[0101] In at least one example, a plurality of sensors (including a scene camera 6-106, a downward camera 6-114, a jaw camera 6-116, a side camera 6-118, a depth projector 6-112, and depth sensors 6-108, 6-110) may be used in combination with an electrically coupled controller to combine depth data with camera data for hand tracking and for size determination to better perform hand tracking and object recognition and tracking functions of the HMD device 6-100. In at least one example, as described above and in Figure 1I The downward camera 6-114, jaw camera 6-116, and side camera 6-118 shown in the figure can be wide-angle cameras capable of operating in the visible and infrared spectrums. In at least one example, these cameras 6-114, 6-116, 6-118 can operate only in black and white light detection to simplify image processing and gain sensitivity.

[0102] Figure 1I Any of the features, components and / or parts shown (including their arrangement and configuration) may be included alone or in any combination in Figures 1J to 1L Any of the other examples of devices, features, components, and parts shown and described herein. Figures 1J to 1LAny of the features, components and / or parts shown and described, including their arrangement and configuration, may be included alone or in any combination in the Figure 1I Examples of equipment, features, assemblies, and parts are shown.

[0103] Figure 1J A lower perspective view of an example of an HMD 6-200 including a cover or shroud 6-204 secured to a frame 6-230 is shown. In at least one example, sensors 6-203 of a sensor system 6-202 may be disposed around the perimeter of the HMD 6-200 such that the sensors 6-203 are disposed outwardly around the perimeter of a display area or area 6-232 so as to not obstruct a view of displayed light. In at least one example, the sensors may be disposed behind the shroud 6-204 and aligned with a transparent portion of the shroud, thereby allowing the sensors and projector to pass light back and forth through the shroud 6-204. In at least one example, opaque ink or other opaque material or film / layer may be disposed on the shroud 6-204 around the display area 6-232 to conceal components of the HMD 6-200 outside of the display area 6-232 rather than the transparent portion defined by the opaque portion through which the sensors and projector transmit and receive light and electromagnetic signals during operation. In at least one example, the shield 6-204 allows light to pass from the display (eg, within the display area 6-232), but does not allow light to pass radially outward from the display area around the display and the perimeter of the shield 6-204.

[0104] In some examples, the shield 6-204 includes a transparent portion 6-205 and an opaque portion 6-207, as described above and elsewhere herein. In at least one example, the opaque portion 6-207 of the shield 6-204 may define one or more transparent areas 6-209 through which the sensors 6-203 of the sensor system 6-202 may transmit and receive signals. In the example shown, the sensors 6-203 of the sensor system 6-202 that transmit and receive signals through the shield 6-204, or more specifically through the transparent areas 6-209 of (or defined by) the opaque portion 6-207 of the shield 6-204, may include sensors 6-203 of the sensor system 6-202 that transmit and receive signals through the shield 6-204, or more specifically through the transparent areas 6-209 of (or defined by) the opaque portion 6-207 of the shield 6-204. Figure 1I The same or similar sensors as those shown in the example of FIG, such as the depth sensors 6-108 and 6-110, the depth projector 6-112, the first and second scene cameras 6-106, the first and second downward cameras 6-114, the first and second side cameras 6-118, and the first and second infrared illuminators 6-124. These sensors are also Figure 1K and Figure 1L Other sensors, sensor types, number of sensors, and their relative positioning may be included in one or more other examples of an HMD.

Figure 1I and Figures 1K to 1L Any of the features, components and / or parts shown and described, including their arrangement and configuration, may be included alone or in any combination in the Figure 1J Examples of equipment, features, assemblies, and parts are shown.

[0106] Figure 1K A front view of a portion of an example of an HMD device 6-300 including a display 6-334, brackets 6-336, 6-338, and a frame or housing 6-330 is shown. Figure 1K The example shown does not include a front cover or shield in order to illustrate the brackets 6-336, 6-338. Figure 1J The illustrated shield 6-204 includes an opaque portion 6-207 that would visually cover / block the view of anything outside the display / display area 6-334 (e.g., radially / peripherally outside the display / display area) (including the sensor 6-303 and bracket 6-338).

[0107] In at least one example, the various sensors of the sensor system 6-302 are coupled to brackets 6-336, 6-338. In at least one example, the scene cameras 6-306 include tight tolerances on angles relative to each other. For example, the tolerance on mounting angles between two scene cameras 6-306 may be 0.5 degrees or less, such as 0.3 degrees or less. To achieve and maintain such tight tolerances, in one example, the scene cameras 6-306 may be mounted to the bracket 6-338 instead of the shield. The bracket may include a cantilever on which the scene camera 6-306 and other sensors of the sensor system 6-302 may be mounted to maintain positioning and orientation in the event of a drop by a user that causes any deformation of the other bracket 6-226, the housing 6-330, and / or the shield.

The sensor system 6-402 may be similar to other sensor systems described above and elsewhere herein, including with reference to Figures 1I to 1K As described. In at least one example, the jaw camera 6-416 may face downward to capture images of the user's lower facial features. In one example, the jaw camera 6-416 may be coupled directly to the frame or housing 6-430 or to one or more internal brackets that are directly coupled to the frame or housing 6-430 as shown. The frame or housing 6-430 may include one or more apertures / openings 6-415 through which the jaw camera 6-416 may transmit and receive signals.

[0111] Figure 1MIllustrated is a rear perspective view of an IPD adjustment system 11.1.1-102 including first and second optical modules 11.1.1-104a-11.1.1-104b slidably engaged / coupled to respective guide rods 11.1.1-108a-11.1.1-108b and motors 11.1.1-110a-11.1.1-110b of left and right adjustment subsystems 11.1.1-106a-11.1.1-106b. The IPD adjustment system 11.1.1-102 may be coupled to a bracket 11.1.1-112 and include a button 11.1.1-114 in electrical communication with the motors 11.1.1-110a-11.1.1-110b. In at least one example, the button 11.1.1-114 can electrically communicate with the first and second motors 11.1.1-110a to 11.1.1-110b via a processor or other circuit component to cause the first and second motors 11.1.1-110a to 11.1.1-110b to activate and cause the first and second optical modules 11.1.1-104a to 11.1.1-104b to change their positioning relative to each other.

[0112] In at least one example, the first and second optical modules 11.1.1-104a-11.1.1-104b may include respective display screens configured to project light toward the user's eyes when the HMD 11.1.1-100 is worn. In at least one example, the user may manipulate (e.g., press and / or rotate) a button 11.1.1-114 to activate positional adjustment of the optical modules 11.1.1-104a-11.1.1-104b to match the interpupillary distance of the user's eyes. The optical modules 11.1.1-104a-11.1.1-104b may also include one or more cameras or other sensors / sensor systems for imaging and measuring the user's IPD, such that the optical modules 11.1.1-104a-11.1.1-104b may be adjusted to match the IPD.

[0113] In one example, a user can manipulate the button 11.1.1-114 to cause automatic position adjustment of the first and second optical modules 11.1.1-104a - 11.1.1-104b. In one example, the user can manipulate the button 11.1.1-114 to cause manual adjustment, causing the optical modules 11.1.1-104a - 11.1.1-104b to move further apart or closer together (e.g., when the user rotates the button 11.1.1-114 one way or the other) until the user visually matches their own IPD. In one example, the manual adjustment is communicated electronically via one or more circuits, and power for moving the optical modules 11.1.1-104a - 11.1.1-104b via the motors 11.1.1-110a - 11.1.1-110b is provided by a power source. In one example, the adjustment and movement of the optical modules 11.1.1-104a to 11.1.1-104b via the manipulation buttons 11.1.1-114 is mechanically actuated via the movement buttons 11.1.1-114.

Likewise, any of the features, components, and / or parts (including arrangements and configurations thereof) shown and described with reference to any other illustrated figures and described herein may be included, alone or in any combination, in any other example of the apparatus, features, components, and parts shown in any other illustrated figures and described herein. Figure 1M Examples of equipment, features, assemblies, and parts are shown.

[0115] Figure 1N A front perspective view of a portion of an HMD 11.1.2-100 is shown, comprising an outer structural frame 11.1.2-102 and an inner or intermediate structural frame 11.1.2-104 defining first and second apertures 11.1.2-106a, 11.1.2-106b. Figure 1N2-106a through 11.1.2-106b may be blocked by one or more other components of the HMD 11.1.2-100 coupled to the inner frame 11.1.2-104 and / or the outer frame 11.1.2-102, as shown. In at least one example, the HMD 11.1.2-100 may include a first mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104. In at least one example, the mounting bracket 11.1.2-108 is coupled to the inner frame 11.1.2-104 between the first and second apertures 11.1.2-106a through 11.1.2-106b.

[0116] The mounting bracket 11.1.2-108 can include a middle or center portion 11.1.2-109 coupled to the inner frame 11.1.2-104. In some examples, the middle or center portion 11.1.2-109 may not be the geometric middle or center of the bracket 11.1.2-108. Instead, the middle / center portion 11.1.2-109 can be disposed between first and second cantilevered extension arms extending away from the middle portion 11.1.2-109. In at least one example, the mounting bracket 108 includes a first cantilevered arm 11.1.2-112 and a second cantilevered arm 11.1.2-114 extending away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104.

[0117] like Figure 1N As shown, the outer frame 11.1.2-102 can define a curved geometry on its lower side to accommodate the user's nose when the user wears the HMD 11.1.2-100. The curved geometry can be referred to as a nose bridge 11.1.2-111 and is centrally located on the underside of the HMD 11.1.2-100 as shown. In at least one example, the mounting bracket 11.1.2-108 can be connected to the inner frame 11.1.2-104 between the holes 11.1.2-106a-11.1.2-106b such that the cantilevered arms 11.1.2-112, 11.1.2-114 extend downwardly and laterally outwardly away from the middle portion 11.1.2-109 to complement the nose bridge 11.1.2-111 geometry of the outer frame 11.1.2-102. In this way, the mounting bracket 11.1.2-108 is configured to accommodate the user's nose, as described above. The geometry of the nose bridge 11.1.2-111 accommodates the nose because the nose bridge 11.1.2-111 provides a curvature that conforms to the shape of the user's nose, providing a comfortable fit from above, over, and around.

[0118] The first cantilever arm 11.1.2-112 can extend in a first direction away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-108, and the second cantilever arm 11.1.2-114 can extend in a second direction opposite to the first direction away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-108. The first cantilever arm 11.1.2-112 and the second cantilever arm 11.1.2-114 are referred to as "cantilevered" or "cantilever" arms because each arm 11.1.2-112, 11.1.2-114 includes a free distal end 11.1.2-116, 11.1.2-118, respectively, which are not attached to the inner frame 11.1.2-102 and the outer frame 11.1.2-104. In this way, the arms 11.1.2-112, 11.1.2-114 depend from the middle portion 11.1.2-109, which is connectable to the inner frame 11.1.2-104, while the distal ends 11.1.2-102, 11.1.2-104 are unattached.

[0119] In at least one example, the HMD 11.1.2-100 may include one or more components coupled to a mounting bracket 11.1.2-108. In one example, the components include a plurality of sensors 11.1.2-110a-f. Each of the plurality of sensors 11.1.2-110a-f may include various types of sensors, including cameras, IR sensors, and the like. In some examples, one or more of the sensors 11.1.2-110a-f may be used for object recognition in three-dimensional space, making it important to maintain precise relative positioning of two or more of the plurality of sensors 11.1.2-110a-f. The cantilevered nature of the mounting bracket 11.1.2-108 may protect the sensors 11.1.2-110a-f from damage and change in positioning if accidentally dropped by a user. Because the sensors 11.1.2-110a-f are cantilevered on the arms 11.1.2-112, 11.1.2-114 of the mounting bracket 11.1.2-108, stresses and deformations of the inner and / or outer frames 11.1.2-104, 11.1.2-102 are not transferred to the cantilevered arms 11.1.2-112, 11.1.2-114 and therefore do not affect the relative positions of the sensors 11.1.2-110a-f coupled / mounted to the mounting bracket 11.1.2-108.

Similarly, any of the features, components, and / or parts shown and described herein (including arrangements and configurations thereof) may be included, alone or in any combination, in any other example of the apparatus, features, components, and other examples described herein. Figure 1N Examples of equipment, features, assemblies, and parts are shown.

[0121] Figure 1O An example of an optical module 11.3.2-100 for use in an electronic device (such as an HMD, including the HMD devices described herein) is shown. As shown in one or more other examples described herein, the optical module 11.3.2-100 can be one of two optical modules within the HMD, where each optical module is aligned to project light toward an eye of a user. In this manner, a first optical module can project light toward a first eye of a user via a display screen, and a second optical module of the same device can project light toward a second eye of the user via another display screen.

[0122] In at least one example, the optical module 11.3.2-100 may include an optical frame or housing 11.3.2-102, which may also be referred to as a barrel or optical module barrel. The optical module 11.3.2-100 may also include a display 11.3.2-104 coupled to the housing 11.3.2-102, the display including one or more display screens. The display 11.3.2-104 may be coupled to the housing 11.3.2-102 such that the display 11.3.2-104 is configured to project light toward the eyes of a user when the HMD to which the display module 11.3.2-100 belongs is worn during use. In at least one example, the housing 11.3.2-102 may surround the display 11.3.2-104 and provide connection features for coupling other components of the optical module described herein.

[0123] In one example, the optical module 11.3.2-100 may include one or more cameras 11.3.2-106 coupled to the housing 11.3.2-102. The cameras 11.3.2-106 may be positioned relative to the display 11.3.2-104 and the housing 11.3.2-102 such that the cameras 11.3.2-106 are configured to capture one or more images of a user's eyes during use. In at least one example, the optical module 11.3.2-100 may also include a light strip 11.3.2-108 surrounding the display 11.3.2-104. In one example, the light strip 11.3.2-108 is disposed between the display 11.3.2-104 and the cameras 11.3.2-106. The light strip 11.3.2-108 may include a plurality of lights 11.3.2-110. The plurality of lights may include one or more light emitting diodes (LEDs) or other lights configured to project light toward the eyes of the user when the HMD is worn. The individual lights 11.3.2-110 in the light strip 11.3.2-108 may be spaced apart around the light strip 11.3.2-108 and thus evenly or unevenly spaced around the display 11.3.2-104 at various locations on the light strip 11.3.2-108 and around the display 11.3.2-104.

[0124] In at least one example, the housing 11.3.2-102 defines a viewing opening 11.3.2-101 through which a user can view the display 11.3.2-104 when wearing the HMD device. In at least one example, the LEDs are configured and arranged to emit light through the viewing opening 11.3.2-101 toward the user's eyes. In one example, the camera 11.3.2-106 is configured to capture one or more images of the user's eyes through the viewing opening 11.3.2-101.

[0125] As mentioned above, Figure 1O Each of the components and features of the illustrated optical module 11.3.2-100 may be replicated in another (eg, second) optical module provided with the HMD to interact with (eg, project light and capture images) the user's other eye.

[0127] Figure 1P A cross-sectional view of an example of an optical module 11.3.2-200 is shown, the optical module including a housing 11.3.2-202, a display assembly 11.3.2-204 coupled to the housing 11.3.2-202, and a lens 11.3.2-216 coupled to the housing 11.3.2-202. In at least one example, the housing 11.3.2-202 defines a first aperture or channel 11.3.2-212 and a second aperture or channel 11.3.2-214. The channels 11.3.2-212, 11.3.2-214 can be configured to slidably engage corresponding tracks or guides of an HMD device to allow the optical module 11.3.2-200 to be adjusted relative to the user's eyes to match the user's interpupillary distance (IPD). The housing 11.3.2-202 can slidably engage the guides to secure the optical module 11.3.2-200 in place within the HMD.

[0128] In at least one example, the optical module 11.3.2-200 may further include a lens 11.3.2-216 coupled to the housing 11.3.2-202 and disposed between the display assembly 11.3.2-204 and the user's eyes when the HMD is worn. The lens 11.3.2-216 may be configured to direct light from the display assembly 11.3.2-204 to the user's eyes. In at least one example, the lens 11.3.2-216 may be part of a lens assembly including a corrective lens that is removably attached to the optical module 11.3.2-200. In at least one example, the lens 11.3.2-216 is disposed above the light strip 11.3.2-208 and the one or more eye tracking cameras 11.3.2-206 such that the camera 11.3.2-206 is configured to capture an image of the user's eyes through the lens 11.3.2-216, and the light strip 11.3.2-208 includes lights configured to project light into the user's eyes through the lens 11.3.2-216 during use.

[0130] Figure 2is a block diagram of an example of the controller 110 in some embodiments. While some specific features are shown, those skilled in the art will recognize from this disclosure that various other features are not shown for the sake of brevity and so as not to obscure more relevant aspects of the embodiments disclosed herein.

[0133] The operating system 230 includes processes for handling various basic system services and for performing hardware-related tasks. In some embodiments, the XR experience module 240 is configured to manage and coordinate single or multiple XR experiences for one or more users (e.g., a single XR experience for one or more users, or multiple XR experiences for corresponding groups of one or more users). To this end, in various embodiments, the XR experience module 240 includes a data acquisition unit 241, a tracking unit 242, a coordination unit 246, and a data transmission unit 248.

[0134] In some embodiments, the data acquisition unit 241 is configured to at least Figure 1A 1 and / or peripherals 195. The display generation component 120 of the embodiment of the present invention may also be used to obtain data (e.g., presentation data, interaction data, sensor data, position data, etc.) from one or more of the input device 125, the output device 155, the sensor 190, and / or the peripheral device 195. To this end, in various embodiments, the data acquisition unit 241 includes instructions and / or logic for instructions and heuristics and metadata for the heuristics.

[0135] In some embodiments, the tracking unit 242 is configured to map the scene 105 and track at least the display generation component 120 relative to the scene 105. Figure 1A 105, and optionally relative to the position / location of one or more of the tracked input device 125, the output device 155, the sensor 190, and / or the peripheral device 195.

In some embodiments, the tracking unit 242 includes a hand tracking unit 244 and / or an eye tracking unit 243. In some embodiments, the hand tracking unit 244 is configured to track the position / location of one or more parts of the user's hand and / or the position / location of one or more parts of the user's hand relative to the user's Figure 1A The movement of the scene 105 relative to the display generation component 120 and / or relative to the coordinate system (the coordinate system is defined relative to the user's hand). Figure 4 The hand tracking unit 244 is described in more detail. In some embodiments, the eye tracking unit 243 is configured to track the position or movement of the user's gaze (or more broadly, the user's eyes, face, or head) relative to the scene 105 (e.g., relative to the physical environment and / or relative to the user (e.g., the user's hands)) or relative to the XR content displayed via the display generation component 120. Figure 5 The eye tracking unit 243 is described in more detail.

[0136] In some embodiments, the coordination unit 246 is configured to manage and coordinate the XR experience presented to the user by the display generation component 120, and optionally by one or more of the output device 155 and / or the peripheral device 195. To this end, in various embodiments, the coordination unit 246 includes instructions and / or logic for the instructions, as well as heuristics and metadata for the heuristics.

[0137] In some embodiments, the data sending unit 248 is configured to send data (e.g., presentation data, position data, etc.) to at least the display generation component 120, and optionally to one or more of the input device 125, the output device 155, the sensor 190, and / or the peripheral device 195. To this end, in various embodiments, the data sending unit 248 includes instructions and / or logic for the instructions, as well as heuristics and metadata for the heuristics.

[0138] Although the data acquisition unit 241, the tracking unit 242 (e.g., including the eye tracking unit 243 and the hand tracking unit 244), the coordination unit 246, and the data sending unit 248 are shown as residing on a single device (e.g., the controller 110), it should be understood that in other embodiments, any combination of the data acquisition unit 241, the tracking unit 242 (e.g., including the eye tracking unit 243 and the hand tracking unit 244), the coordination unit 246, and the data sending unit 248 can be located in separate computing devices.

[0139] also, Figure 2 It serves more as a functional description of various features that may be present in a particular implementation, rather than as a structural diagram of the embodiments described herein. As one of ordinary skill in the art will recognize, items shown separately may be combined, and some items may be separated. For example, Figure 2 Some functional modules shown separately in the figure may be implemented in a single module, and the various functions of a single functional block may be implemented by one or more functional blocks in various embodiments. The actual number of modules and the division of specific functions and how features are distributed among them will vary depending on the specific implementation and, in some embodiments, will depend in part on the specific combination of hardware, software, and / or firmware selected for a particular implementation.

[0140] Figure 3is a block diagram of an example of the display generation component 120 in some embodiments. While some specific features are shown, those skilled in the art will recognize from this disclosure that various other features are not shown for the sake of brevity and so as not to obscure more relevant aspects of the embodiments disclosed herein. To this end, as a non-limiting example, in some embodiments, the display generation component 120 (e.g., an HMD) includes one or more processing units 302 (e.g., a microprocessor, an ASIC, an FPGA, a GPU, a CPU, a processing core, etc.), one or more input / output (I / O) devices and sensors 306, one or more communication interfaces 308 (e.g., USB, FIREWIRE, THUNDERBOLT, IEEE 802.3x, IEEE 802.11x, IEEE802.16x, GSM, CDMA, TDMA, GPS, IR, Bluetooth, ZIGBEE, and / or similar types of interfaces), one or more programming (e.g., I / O) interfaces 310, one or more XR displays 312, one or more optional internal-facing and / or external-facing image sensors 314, memory 320, and one or more communication buses 304 for interconnecting these and various other components.

In some embodiments, the one or more image sensors 314 are configured to acquire image data corresponding to the user's hands and, optionally, at least a portion of the user's arms (and may be referred to as a hand-tracking camera). In some embodiments, the one or more image sensors 314 are configured to face forward so as to acquire image data corresponding to the scene that the user would see in the absence of the display generation component 120 (e.g., an HMD) (and may be referred to as a scene camera). The one or more optional image sensors 314 may include one or more RGB cameras (e.g., having a complementary metal oxide semiconductor (CMOS) image sensor or a charge coupled device (CCD) image sensor), one or more infrared (IR) cameras, and / or one or more event-based cameras, among others.

[0144] Memory 320 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid-state memory devices. In some embodiments, memory 320 includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid-state storage devices. Memory 320 optionally includes one or more storage devices located away from one or more processing units 302. Memory 320 includes non-transitory computer-readable storage media. In some embodiments, memory 320 or a non-transitory computer-readable storage medium of memory 320 stores the following programs, modules, and data structures, or a subset thereof, including an optional operating system 330 and an XR rendering module 340.

[0145] The operating system 330 includes processes for handling various basic system services and for performing hardware-related tasks. In some embodiments, the XR rendering module 340 is configured to present XR content to the user via one or more XR displays 312. To this end, in various embodiments, the XR rendering module 340 includes a data acquisition unit 342, an XR rendering unit 344, an XR map generation unit 346, and a data transmission unit 348.

[0146] In some embodiments, the data acquisition unit 342 is configured to at least Figure 1A The controller 110 acquires data (e.g., presentation data, interaction data, sensor data, location data, etc.). To this end, in various embodiments, the data acquisition unit 342 includes instructions and / or logic for instructions and heuristics and metadata for the heuristics.

[0147] In some embodiments, the XR rendering unit 344 is configured to render XR content via one or more XR displays 312. To this end, in various embodiments, the XR rendering unit 344 includes instructions and / or logic for instructions as well as heuristics and metadata for the heuristics.

[0148] In some embodiments, the XR map generation unit 346 is configured to generate an XR map (e.g., a 3D map of a mixed reality scene or a map of a physical environment in which computer-generated objects can be placed to generate an extended reality) based on the media content data. To this end, in various embodiments, the XR map generation unit 346 includes instructions and / or logic for the instructions, as well as heuristics and metadata for the heuristics.

[0149] In some embodiments, the data sending unit 348 is configured to send data (e.g., presentation data, position data, etc.) to at least the controller 110, and optionally to one or more of the input device 125, the output device 155, the sensor 190, and / or the peripheral device 195. To this end, in various embodiments, the data sending unit 348 includes instructions and / or logic for the instructions, as well as heuristics and metadata for the heuristics.

[0150] Although the data acquisition unit 342, the XR rendering unit 344, the XR map generation unit 346, and the data transmission unit 348 are shown as residing on a single device (e.g., Figure 1A , but it should be understood that in other embodiments, any combination of the data acquisition unit 342, the XR rendering unit 344, the XR map generation unit 346, and the data sending unit 348 may be located in a separate computing device.

[0151] also, Figure 3 It serves more as a functional description of various features that may be present in a particular implementation, rather than as a structural diagram of the embodiments described herein. As one of ordinary skill in the art will recognize, items shown separately may be combined, and some items may be separated. For example, Figure 3 Some functional modules shown separately in the figure may be implemented in a single module, and the various functions of a single functional block may be implemented by one or more functional blocks in various embodiments. The actual number of modules and the division of specific functions and how features are distributed among them will vary depending on the specific implementation and, in some embodiments, will depend in part on the specific combination of hardware, software, and / or firmware selected for a particular implementation.

[0152] Figure 4 is a schematic illustration of an example embodiment of a hand tracking device 140. In some embodiments, the hand tracking device 140 ( Figure 1A ) is controlled by the hand tracking unit 244 ( Figure 2 ) to track the position / location of one or more parts of the user's hand, and / or the movement of one or more parts of the user's hand relative to the scene 105 of Figure 1 (e.g., relative to a portion of the physical environment surrounding the user, relative to the display generation component 120, or relative to a portion of the user (e.g., the user's face, eyes, or head), and / or relative to a coordinate system (which is defined relative to the user's hand)). In some embodiments, the hand tracking device 140 is part of the display generation component 120 (e.g., embedded in or attached to the head-mounted device). In some embodiments, the hand tracking device 140 is separate from the display generation component 120 (e.g., located in a separate housing or attached to a separate physical support structure).

[0153] In some embodiments, hand tracking device 140 includes an image sensor 404 (e.g., one or more IR cameras, 3D cameras, depth cameras, and / or color cameras, etc.) that captures three-dimensional scene information, including at least a human user's hand 406. Image sensor 404 captures hand images at a sufficient resolution to enable the fingers and their respective positioning to be distinguished. Image sensor 404 typically captures images of other parts of the user's body, or may also capture images of all parts of the body, and may include zoom capabilities or specialized sensors with increased magnification to capture hand images at a desired resolution. In some embodiments, image sensor 404 also captures 2D color video images of hand 406 and other elements of the scene. In some embodiments, image sensor 404 is used in conjunction with other image sensors to capture the physical environment of scene 105, or serves as an image sensor for capturing the physical environment of scene 105. In some embodiments, the image sensor is positioned relative to the user or the user's environment in such a way that the field of view of image sensor 404, or a portion thereof, is used to define an interaction space in which hand movements captured by the image sensor are interpreted as input to controller 110.

[0154] In some embodiments, the image sensor 404 outputs a sequence of frames containing 3D image data (and possibly color image data) to the controller 110, which extracts high-level information from the image data. This high-level information is typically provided to an application running on the controller via an application program interface (API), which in turn drives the display generation component 120. For example, a user can interact with the software running on the controller 110 by moving his hand 406 and changing his hand pose.

[0155] In some embodiments, image sensor 404 projects a speckled pattern onto a scene containing hand 406 and captures an image of the projected pattern. In some embodiments, controller 110 calculates the 3D coordinates of points in the scene (including points on the surface of the user's hand) by triangulation based on the lateral offsets of the spots in the pattern. This approach is advantageous because it does not require the user to hold or wear any kind of beacon, sensor, or other marker. The approach gives the depth coordinates of points in the scene relative to a predetermined reference plane at a specific distance from image sensor 404. In this disclosure, it is assumed that image sensor 404 defines an orthogonal set of x-, y-, and z-axes, such that the depth coordinates of points in the scene correspond to the z component measured by the image sensor. Alternatively, image sensor 404 (e.g., a hand tracking device) may use other 3D mapping methods based on single or multiple cameras or other types of sensors, such as stereo imaging or time-of-flight measurement.

[0156] In some embodiments, the hand tracking device 140 captures and processes a time series of depth maps containing the user's hand as the user moves their hand (e.g., the entire hand or one or more fingers). Software running on the image sensor 404 and / or the processor in the controller 110 processes the 3D map data to extract image patch descriptors of the hand from these depth maps. The software can match these descriptors with image patch descriptors stored in the database 408 based on a previous learning process to estimate the pose of the hand in each frame. The pose typically includes the 3D positions of the user's hand joints and fingertips.

[0157] The software can also analyze the trajectory of the hand and / or finger over multiple frames in the sequence to identify gestures. The pose estimation functionality described herein can be interleaved with the motion tracking functionality, such that patch-based pose estimation is performed only once every two (or more) frames, while tracking is used to find pose changes that occur over the remaining frames. Pose, motion, and gesture information is provided to an application running on the controller 110 via the aforementioned API. The application can, for example, move and modify the image presented on the display generation component 120 in response to the pose and / or gesture information, or perform other functions.

[0158] In some embodiments, gestures include air gestures. An air gesture is a gesture that is detected without the user touching an input element that is part of a device (e.g., computer system 101, one or more input devices 125, and / or hand tracking device 140) (or independent of an input element that is part of the device) and is based on detected movement of a part of the user's body (e.g., head, one or both arms, one or both hands, one or more fingers, and / or one or both legs) through air (including movement of the user's body relative to an absolute reference (e.g., the angle of the user's arms relative to the ground or the distance of the user's hands relative to the ground), movement relative to another part of the user's body (e.g., movement of the user's hand relative to the user's shoulder, movement of one of the user's hands relative to the user's other hand, and / or movement of a user's fingers relative to another finger or part of the user's hand), and / or absolute movement of a part of the user's body (e.g., a tap gesture comprising a hand moving a predetermined amount and / or speed in a predetermined pose, or a shake gesture comprising a predetermined speed or amount of rotation of a part of the user's body).

[0159] In some embodiments, the input gestures used in the various examples and embodiments described herein include in-air gestures for interacting with an XR environment (e.g., a virtual or mixed reality environment) performed in some embodiments by movement of a user's fingers relative to other fingers (or parts of the user's hands). In some embodiments, an in-air gesture is a gesture detected without the user touching an input element that is part of the device (or independently of an input element that is part of the device) and based on detected movement of a part of the user's body through the air (including movement of the user's body relative to an absolute reference (e.g., the angle of the user's arm relative to the ground or the distance of the user's hand relative to the ground), movement relative to another part of the user's body (e.g., movement of the user's hand relative to the user's shoulder, movement of one of the user's hands relative to the user's other hand, and / or movement of a user's finger relative to another finger or part of the user's hand), and / or absolute movement of a part of the user's body (e.g., a tap gesture comprising a hand moving a predetermined amount and / or speed in a predetermined pose, or a shake gesture comprising a predetermined speed or amount of rotation of a part of the user's body).

[0160] In some embodiments where the input gesture is an in-air gesture (e.g., in the absence of physical contact with an input device that provides information to the computer system about which user interface element is the target of user input, such as contact with a user interface element displayed on a touch screen, or contact with a mouse or trackpad to move a cursor to a user interface element), the gesture takes into account the user's attention (e.g., gaze) to determine the target of the user input (e.g., for direct input, as described below). Thus, in embodiments involving in-air gestures, for example, the input gesture is combined (e.g., simultaneously) with movement of the user's fingers and / or hand to detect attention (e.g., gaze) toward a user interface element to perform a pinch and / or tap input, as described below.

[0161] In some embodiments, an input gesture directed at a user interface object is performed directly or indirectly with reference to the user interface object. For example, when an input gesture is performed with the user's hand at a location corresponding to the location of the user interface object in a three-dimensional environment (e.g., as determined based on the user's current viewpoint), user input is performed directly on the user interface object. In some embodiments, when user attention (e.g., gaze) is detected on the user interface object, an input gesture is performed indirectly on the user interface object based on the user's hand being positioned not at the location corresponding to the location of the user interface object in the three-dimensional environment while the user is performing the input gesture. For example, for a direct input gesture, a user can direct user input to the user interface object by initiating a gesture at or near a location corresponding to the displayed location of the user interface object (e.g., within 0.5 cm, 1 cm, 5 cm, or a distance between 0 and 5 cm measured from an outer edge of an option or a center portion of an option). For an indirect input gesture, a user can direct user input to the user interface object by focusing on the user interface object (e.g., by gazing at the user interface object), and while focusing on the option, the user initiates an input gesture (e.g., at any location detectable by the computer system) (e.g., at a location not corresponding to the displayed location of the user interface object).

[0162] In some embodiments, input gestures (e.g., air gestures) used in the various examples and embodiments described herein include pinch inputs and tap inputs for interacting with a virtual or mixed reality environment in some embodiments. For example, the pinch inputs and tap inputs described below are performed as air gestures.

[0163] In some embodiments, a pinch input is part of an air gesture that includes one or more of: a pinch gesture, a long pinch gesture, a pinch and drag gesture, or a double pinch gesture. For example, a pinch gesture as an air gesture includes movement of two or more fingers of a hand to contact each other, i.e., optionally followed by a breaking of contact with each other immediately (e.g., within 0 to 1 second). A long pinch gesture as an air gesture includes movement of two or more fingers of a hand in contact with each other for at least a threshold amount of time (e.g., at least 1 second) before a break in contact with each other is detected. For example, a long pinch gesture includes the user maintaining a pinch gesture (e.g., in which the two or more fingers are in contact), and the long pinch gesture continues until a break in contact between the two or more fingers is detected. In some embodiments, a double pinch gesture as an air gesture includes two (e.g., more) pinch inputs (e.g., performed by the same hand) that are detected consecutively immediately (e.g., within a predefined time period) with each other. For example, the user performs a first pinch input (e.g., a pinch input or a long pinch input), releases the first pinch input (e.g., breaks contact between two or more fingers), and performs a second pinch input within a predefined time period (e.g., within 1 second or within 2 seconds) after releasing the first pinch input.

[0164] In some embodiments, a pinch and drag gesture as an air gesture includes a pinch gesture (e.g., a pinch gesture or a long pinch gesture) performed in conjunction with (e.g., following) a drag input that changes the position of the user's hand from a first position (e.g., the starting position of the drag) to a second position (e.g., the ending position of the drag). In some embodiments, the user maintains the pinch gesture while performing the drag input and releases the pinch gesture (e.g., opens their two or more fingers) to end the drag gesture (e.g., at the second position). In some embodiments, the pinch input and the drag input are performed by the same hand (e.g., the user pinches two or more fingers to contact each other and moves the same hand to a second position in the air using a drag gesture). In some embodiments, the pinch input is performed by the user's first hand and the drag input is performed by the user's second hand (e.g., the user's second hand moves from the first position to the second position in the air while the user continues the pinch input with the user's first hand). In some embodiments, an input gesture as an air gesture includes input performed using both hands of the user (e.g., a pinch and / or tap input). For example, the input gesture includes two (e.g., more) pinch inputs performed in conjunction with each other (e.g., concurrently or within a predefined time period). For example, a first pinch gesture (e.g., a pinch input, a long pinch input, or a pinch and drag input) is performed using a first hand of a user, and a second pinch input is performed using another hand (e.g., a second hand of the user) in conjunction with the pinch input performed using the first hand. In some embodiments, movement between the user's two hands (e.g., increasing and / or decreasing the distance or relative orientation between the user's two hands) is performed.

[0165] In some embodiments, a tap input performed as an air gesture (e.g., pointing to a user interface element) includes movement of a user's finger toward the user interface element, movement of the user's hand toward the user interface element (optionally, extension of the user's finger toward the user interface element), a downward motion of the user's finger (e.g., mimicking a mouse click motion or a tap on a touch screen), or other predefined movement of the user's hand. In some embodiments, a tap input performed as an air gesture is detected based on movement characteristics of the finger or hand performing the tap gesture movement of the finger or hand, which is a movement of the finger or hand away from the user's viewpoint and / or toward an object that is the target of the tap input, followed by an end of the movement. In some embodiments, the end of the movement is detected based on a change in movement characteristics of the finger or hand performing the tap gesture (e.g., the end of movement away from the user's viewpoint and / or toward an object that is the target of the tap input, a reversal of the direction of movement of the finger or hand, and / or a reversal of the acceleration direction of the movement of the finger or hand).

[0166] In some embodiments, the user's attention is determined to be directed toward a portion of the three-dimensional environment based on detection of a gaze directed toward the portion of the three-dimensional environment (optionally, no other conditions are required). In some embodiments, the user's attention is determined to be directed toward a portion of the three-dimensional environment based on detection of a gaze directed toward the portion of the three-dimensional environment using one or more additional conditions, such as requiring the gaze to be directed toward the portion of the three-dimensional environment for at least a threshold duration (e.g., a dwell duration) and / or requiring the gaze to be directed toward the portion of the three-dimensional environment when the user's viewpoint is within a distance threshold from the portion of the three-dimensional environment, so that the device determines that the user's attention is directed toward the portion of the three-dimensional environment, wherein if one of these additional conditions is not met, the device determines that the attention is not directed toward the portion of the three-dimensional environment to which the gaze is directed (e.g., until the one or more additional conditions are met).

[0167] In some embodiments, the detection of a ready state configuration of a user or a portion of a user is detected by a computer system. The detection of the ready state configuration of a hand is used by the computer system as an indication that the user may be preparing to interact with the computer system using one or more mid-air gesture inputs performed by the hand (e.g., a pinch, a tap, a pinch and drag, a double pinch, a long pinch, or other mid-air gestures described herein). For example, the ready state of a hand is determined based on whether the hand has a predetermined hand shape (e.g., a pre-pinch shape with the thumb and one or more fingers extended and spaced apart in preparation for a pinch or grab gesture, or a pre-tap shape with one or more fingers extended and the palm facing away from the user), based on whether the hand is in a predetermined position relative to the user's viewpoint (e.g., below the user's head and above the user's waist and extending at least 15 cm, 20 cm, 25 cm, 30 cm, or 50 cm from the body), and / or based on whether the hand has moved in a particular manner (e.g., toward an area in front of the user above the user's waist and below the user's head, or away from the user's body or legs). In some embodiments, the ready state is used to determine whether an interactive element of a user interface responds to attention (eg, gaze) input.

[0168] In scenarios where input is described with reference to in-air gestures, it should be understood that similar gestures can be detected using a hardware input device attached to or held by one or both hands of a user, where the positioning of the hardware input device in space can be tracked using optical tracking, one or more accelerometers, one or more gyroscopes, one or more magnetometers, and / or one or more inertial measurement units, and the positioning and / or movement of the hardware input device is used instead of the positioning and / or movement of one or both hands in the corresponding in-air gesture. In scenarios where input is described with reference to in-air gestures, it should be understood that similar gestures can be detected using a hardware input device attached to or held by one or both hands of a user, and user input can be detected using controls contained in the hardware input device, such as one or more touch-sensitive input elements, one or more pressure-sensitive input elements, one or more buttons, one or more knobs, one or more dials, one or more joysticks, one or more hand or finger overlays that can detect the position or change in position of parts of a hand and / or finger relative to each other, relative to the user's body and / or relative to the user's physical environment, and / or other hardware input device controls, wherein user input performed using the controls contained in the hardware input device is used in place of a hand and / or finger gesture such as an air tap or air pinch in the corresponding in-air gesture. For example, a selection input described as being performed using an air tap or air pinch input can alternatively be detected using a button press, a tap on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input. As another example, movement input described as being performed using a mid-air pinch and drag may alternatively be detected based on interaction with a hardware input control, such as a button press and hold, a touch on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input following movement of a hardware input device (e.g., along with a hand associated with the hardware input device) through space. Similarly, two-handed input involving movement of hands relative to each other may be performed using one mid-air gesture and one hardware input device in the hand that is not performing the mid-air gesture, two hardware input devices held in different hands, or two mid-air gestures performed by different hands using various combinations of mid-air gestures and / or inputs detected by one or more of the aforementioned hardware input devices.

[0169] In some embodiments, the software may be downloaded to the controller 110 in electronic form, for example, over a network, or may alternatively be provided on tangible, non-transitory media such as optical, magnetic, or electronic memory media. In some embodiments, the database 408 is also stored in memory associated with the controller 110. Alternatively or additionally, some or all of the described functions of the computer may be implemented in dedicated hardware, such as a custom or semi-custom integrated circuit or a programmable digital signal processor (DSP). Although in Figure 4, but some or all of the processing functions of the controller may be performed by a suitable microprocessor and software, or by dedicated circuitry within the housing of the image sensor 404 (e.g., a hand tracking device), or other devices associated with the image sensor 404. In some embodiments, at least some of these processing functions may be performed by a suitable processor integrated with the display generation component 120 (e.g., in a television receiver, handheld device, or head-mounted device), or with any other suitable computerized device (such as a game console or media player). The sensing functions of the image sensor 404 may also be integrated into a computer or other computerized device to be controlled by the sensor output.

[0170] Figure 4 Also included is a schematic representation of a depth map 410 captured by the image sensor 404 in some embodiments. As described above, the depth map comprises a matrix of pixels having corresponding depth values. Pixels 412 corresponding to the hand 406 have been segmented from the background and wrist in this figure. The brightness of each pixel within the depth map 410 is inversely proportional to its depth value (i.e., the measured z-distance from the image sensor 404), with shades of gray becoming darker with increasing depth. The controller 110 processes these depth values ​​to identify and segment components of the image (i.e., a group of adjacent pixels) that have characteristics of a human hand. These characteristics may include, for example, overall size, shape, and motion from frame to frame in the depth map sequence.

[0171] Figure 4 Also schematically shown is a hand skeleton 414 that the controller 110 ultimately extracts from the depth map 410 of the hand 406 in some embodiments. Figure 4 , a hand skeleton 414 is superimposed on a hand background 416 that has been segmented from the original depth map. In some embodiments, key feature points of the hand and, optionally, on the wrist or arm connected to the hand (e.g., points corresponding to knuckles, finger tips, the center of the palm, the end of the hand connected to the wrist, etc.) are identified and located on the hand skeleton 414. In some embodiments, the controller 110 uses the position and movement of these key feature points over multiple image frames to determine, in some embodiments, a gesture performed by the hand or the current state of the hand.

[0172] Figure 5 The eye tracking device 130 ( Figure 1A ). In some embodiments, the eye tracking device 130 is composed of an eye tracking unit 243 ( Figure 2) controls to track the position and movement of the user's gaze relative to the scene 105 or relative to the XR content displayed via the display generation component 120. In some embodiments, the eye tracking device 130 is integrated with the display generation component 120. For example, in some embodiments, when the display generation component 120 is a head-mounted device (such as a headset, helmet, goggles, or glasses) or a handheld device placed in a wearable frame, the head-mounted device includes both components for generating XR content for the user to view and components for tracking the user's gaze relative to the XR content. In some embodiments, the eye tracking device 130 is separate from the display generation component 120. For example, when the display generation component is a handheld device or an XR room, the eye tracking device 130 is optionally a device separate from the handheld device or the XR room. In some embodiments, the eye tracking device 130 is a head-mounted device or a portion of the head-mounted device. In some embodiments, the head-mounted eye tracking device 130 is optionally used in conjunction with a display generation component that is also head-mounted or a display generation component that is not head-mounted. In some embodiments, the eye tracking device 130 is not a head-mounted device and is optionally used in conjunction with a head-mounted display generation component. In some embodiments, the eye tracking device 130 is not a head-mounted device and is optionally part of a non-head-mounted display generation component.

[0173] In some embodiments, the display generation component 120 uses a display mechanism (e.g., a left near-eye display panel and a right near-eye display panel) to display a frame including left and right images in front of the user's eyes, thereby providing the user with a 3D virtual view. For example, the head-mounted display generation component may include left and right optical lenses (referred to herein as eye lenses) positioned between the display and the user's eyes. In some embodiments, the display generation component may include or be coupled to one or more external cameras that capture video of the user's environment for display. In some embodiments, the head-mounted display generation component may include a transparent or translucent display, and display virtual objects on the transparent or translucent display, through which the user can directly view the physical environment. In some embodiments, the display generation component projects the virtual objects into the physical environment. For example, the virtual objects may be projected onto a physical surface or as holograms, allowing the individual using the system to observe the virtual objects superimposed on the physical environment. In this case, separate display panels and image frames for the left and right eyes may not be required.

[0174] like Figure 5As shown in , in some embodiments, an eye tracking device 130 (e.g., a gaze tracking device) includes at least one eye tracking camera (e.g., an infrared (IR) or near-infrared (NIR) camera) and an illumination source (e.g., an IR or NIR light source, such as an array or ring of LEDs) that emits light (e.g., IR or NIR light) toward a user's eyes. The eye tracking camera can be pointed toward the user's eyes to receive IR or NIR light reflected directly from the eyes by the light source, or alternatively can be pointed toward "hot" mirrors located between the user's eyes and the display panel, which reflect IR or NIR light from the eyes toward the eye tracking camera while allowing visible light to pass through. The eye tracking device 130 optionally captures images of the user's eyes (e.g., as a video stream captured at 60-120 frames per second (fps)), analyzes these images to generate gaze tracking information, and transmits the gaze tracking information to the controller 110. In some embodiments, both eyes of the user are tracked separately by corresponding eye tracking cameras and illumination sources. In some embodiments, only one eye of the user is tracked by corresponding eye tracking cameras and illumination sources.

[0175] In some embodiments, the eye tracking device 130 is calibrated using a device-specific calibration process to determine the parameters of the eye tracking device for a specific operating environment 100, such as the 3D geometry and parameters of the LED, camera, thermal mirror (if present), eye lens, and display screen. The device-specific calibration process can be performed at a factory or another facility before the AR / VR equipment is delivered to the end user. The device-specific calibration process can be an automatic calibration process or a manual calibration process. The user-specific calibration process can include estimating eye parameters for a specific user, such as pupil position, fovea position, optical axis, visual axis, eye distance, etc. In some embodiments, once the device-specific parameters and user-specific parameters are determined for the eye tracking device 130, a flash-assisted method can be used to process the images captured by the eye tracking camera to determine the user's current visual axis and gaze point relative to the display.

[0176] like Figure 5As shown in FIG, an eye tracking device 130 (e.g., 130A or 130B) includes an eye lens 520 and a gaze tracking system including at least one eye tracking camera 540 (e.g., an infrared (IR) or near infrared (NIR) camera) positioned on the side of the user's face on which eye tracking is being performed, and an illumination source 530 (e.g., an IR or NIR light source, such as an array or ring of NIR light emitting diodes (LEDs)) that emits light (e.g., IR or NIR light) toward the user's eye 592. The eye tracking camera 540 may be directed toward a mirror 550 (the mirrors reflecting the IR or NIR light from the eye 592 while allowing visible light to pass through) positioned between the user's eye 592 and a display 510 (e.g., a left display panel or a right display panel of a head-mounted display, or a display of a handheld device, a projector, etc.). Figure 5 ), or alternatively may be directed toward the user's eye 592 to receive reflected IR or NIR light from the eye 592 (e.g., as shown in the top portion of Figure 5 (as shown in the bottom portion of the ).

[0177] In some embodiments, the controller 110 renders AR or VR frames 562 (e.g., left and right frames for left and right display panels) and provides the frames 562 to the display 510. The controller 110 uses the gaze tracking input 542 from the eye tracking camera 540 for various purposes, such as processing the frames 562 for display. The controller 110 optionally estimates the user's gaze point on the display 510 based on the gaze tracking input 542 obtained from the eye tracking camera 540 using a flash-assisted method or other suitable method. The gaze point estimated from the gaze tracking input 542 is optionally used to determine the direction the user is currently looking.

[0178] The following describes several possible use cases for the user's current gaze direction and is not intended to be limiting. As an example use case, the controller 110 may render virtual content differently based on the determined direction of the user's gaze. For example, the controller 110 may generate virtual content at a higher resolution in the foveal region, determined based on the user's current gaze direction, than in the peripheral region. As another example, the controller may position or move virtual content within the view based at least in part on the user's current gaze direction. As another example, the controller may display specific virtual content within the view based at least in part on the user's current gaze direction. As another example use case in an AR application, the controller 110 may direct an external camera used to capture the physical environment of an XR experience to focus in the determined direction. The external camera's autofocus mechanism may then focus on an object or surface in the environment on the display 510 that the user is currently looking at. As another example use case, the eye lens 520 may be a focusable lens, and the controller may use gaze tracking information to adjust the focus of the eye lens 520 so that the virtual object the user is currently looking at has the appropriate vergence to match the convergence of the user's eye 592. The controller 110 can use the gaze tracking information to guide the eye lens 520 to adjust the focus so that nearby objects that the user is looking at appear at the correct distance.

[0179] In some embodiments, the eye tracking device is part of a head-mounted device that includes a display (e.g., display 510), two eye lenses (e.g., eye lenses 520), an eye tracking camera (e.g., eye tracking camera 540), and a light source (e.g., light source 530 (e.g., IR or NIR LED)) mounted in a wearable housing. The light source emits light (e.g., IR or NIR light) toward the user's eyes 592. In some embodiments, the light sources can be arranged in a ring or circle around each of the lenses, such as Figure 5 In some embodiments, for example, eight light sources 530 (eg, LEDs) are arranged around each lens 520. However, more or fewer illumination sources 530 can be used, and other arrangements and locations of illumination sources 530 can be used.

[0180] In some embodiments, the display 510 emits light in the visible range and does not emit light in the IR or NIR ranges, and therefore does not introduce noise into the gaze tracking system. Note that the positions and angles of the eye-tracking cameras 540 are given by way of example and are not intended to be limiting. In some embodiments, a single eye-tracking camera 540 is located on each side of the user's face. In some embodiments, two or more NIR cameras 540 may be used on each side of the user's face. In some embodiments, a camera 540 with a wider field of view (FOV) and a camera 540 with a narrower FOV may be used on each side of the user's face. In some embodiments, a camera 540 operating at one wavelength (e.g., 850 nm) and a camera 540 operating at a different wavelength (e.g., 940 nm) may be used on each side of the user's face.

[0181] like Figure 5 The illustrated embodiments of the gaze tracking system may be used, for example, in computer-generated reality, virtual reality, and / or mixed reality applications to provide a user with a computer-generated reality, virtual reality, augmented reality, and / or enhanced virtual experience.

[0182] Figure 6 FIGURE 1 shows a flash-assisted gaze tracking pipeline in some embodiments. In some embodiments, the gaze tracking pipeline is implemented by a flash-assisted gaze tracking system (e.g., Figure 1A and Figure 5 The flash-assisted gaze tracking system can maintain a tracking state. Initially, the tracking state is off or "no." While in the tracking state, the flash-assisted gaze tracking system uses information from previous frames when analyzing the current frame to track the pupil outline and glint in the current frame. When not in the tracking state, the flash-assisted gaze tracking system attempts to detect the pupil and glint in the current frame, and if successful, initializes the tracking state to "yes" and continues in the tracking state for the next frame.

[0183] like Figure 6 As shown in , the gaze tracking camera can capture left and right images of the user's left and right eyes. The captured images are then input to the gaze tracking pipeline for processing starting at 610. As indicated by the arrow returning to element 600, the gaze tracking system can continue to capture images of the user's eyes at a rate of, for example, 60 to 120 frames per second. In some embodiments, each set of captured images can be input to the pipeline for processing. However, in some embodiments or under some conditions, not all captured frames are processed by the pipeline.

[0184] At 610, for the currently captured image, if the tracking status is yes, the method proceeds to element 640. At 610, if the tracking status is no, the image is analyzed to detect the user's pupil and glint in the image, as indicated at 620. At 630, if the pupil and glint are successfully detected, the method proceeds to element 640. Otherwise, the method returns to element 610 to process the next image of the user's eye.

[0185] At 640, if proceeding from element 610, the current frame is analyzed to track the pupil and glint based in part on previous information from the previous frame. At 640, if proceeding from element 630, the tracking state is initialized based on the pupil and glint detected in the current frame. The processing result at element 640 is checked to verify that the tracking or detection result is reliable. For example, the result can be checked to determine whether the pupil and a sufficient number of glints were successfully tracked or detected in the current frame to perform gaze estimation. At 650, if the result is unlikely to be reliable, at element 660, the tracking state is set to no, and the method returns to element 610 to process the next image of the user's eye. At 650, if the result is reliable, the method proceeds to element 670. At 670, the tracking state is set to yes (if not already yes), and the pupil and glint information is passed to element 680 to estimate the user's gaze point.

[0186] Figure 6 This is intended to be used as an example of eye tracking technology that may be used for a particular implementation. As one of ordinary skill in the art will appreciate, in some embodiments, other eye tracking technologies currently existing or developed in the future may be used in computer system 101 in place of or in combination with the flash-assisted eye tracking technology described herein to provide an XR experience to a user.

[0187] In some embodiments, the captured portion of the real-world environment 602 is used to provide an XR experience to the user, such as a mixed reality environment in which one or more virtual objects are overlaid on top of the representation of the real-world environment 602.

[0188] Thus, the description herein describes some embodiments of a three-dimensional environment (e.g., an XR environment) that includes representations of real-world objects and representations of virtual objects. For example, the three-dimensional environment optionally includes a representation of a table present in a physical environment, which is captured and displayed in the three-dimensional environment (e.g., actively displayed via a computer system's camera and display, or passively displayed via a transparent or semi-transparent display of the computer system). As previously described, the three-dimensional environment is optionally a mixed reality system, wherein the three-dimensional environment is based on a physical environment captured by one or more sensors of the computer system and displayed via a display generation component. As a mixed reality system, the computer system optionally is capable of selectively displaying portions and / or objects of the physical environment such that the corresponding portions and / or objects of the physical environment appear as if they exist in the three-dimensional environment displayed by the computer system. Similarly, the computer system optionally is capable of displaying virtual objects in the three-dimensional environment such that they appear as if they exist in the real world (e.g., the physical environment) by placing the virtual objects at corresponding locations in the three-dimensional environment that have corresponding locations in the real world. For example, the computer system optionally displays a vase such that the vase appears as if a real vase were placed on top of a table in the physical environment. In some embodiments, a corresponding location in the three-dimensional environment has a corresponding location in the physical environment. Thus, when a computer system is described as displaying a virtual object at a corresponding location relative to a physical object (e.g., such as at or near a user's hand or at or near a physical table), the computer system displays the virtual object at a particular location in the three-dimensional environment such that it appears as if the virtual object is at or near the physical object in the physical environment (e.g., the virtual object is displayed at a location in the three-dimensional environment that corresponds to the location in the physical environment where the virtual object would be displayed if it were a real object at that particular location).

[0189] In some embodiments, real-world objects present in the physical environment that are displayed in the three-dimensional environment (e.g., and / or visible via a display generation component) can interact with virtual objects that exist only in the three-dimensional environment. For example, the three-dimensional environment may include a table and a vase placed on top of the table, where the table is a view (or representation) of a physical table in the physical environment and the vase is a virtual object.

[0190] In a three-dimensional environment (e.g., a real environment, a virtual environment, or an environment that includes a mixture of real and virtual objects), objects are sometimes referred to as having depth or simulated depth, or objects are referred to as being visible, displayed, or placed at different depths. In this context, depth refers to a dimension other than height or width. In some embodiments, depth is defined relative to a fixed set of coordinates (e.g., where a room or object has a height, depth, and width defined relative to a fixed set of coordinates). In some embodiments, depth is defined relative to a user's position or viewpoint, in which case the depth dimension varies based on the user's position and / or the position and angle of the user's viewpoint. In some embodiments where depth is defined relative to the user's position relative to a surface of the environment (e.g., the surface of the floor or ground of the environment), objects that are farther away from the user along a line extending parallel to the surface are considered to have greater depth in the environment, and / or the depth of objects is measured along an axis extending outward from the user's position and parallel to the surface of the environment (e.g., depth is defined in a cylindrical or substantially cylindrical coordinate system where the user's position is at the center of a cylinder extending from the user's head toward the user's feet). In some embodiments where depth is defined relative to a user's viewpoint (e.g., relative to a direction of a point in space that determines which portion of an environment is visible via a head-mounted device or other display), objects that are farther away from the user's viewpoint along a line extending parallel to the user's viewpoint are considered to have greater depth in the environment, and / or the depth of objects is measured along an axis extending outward from the user's viewpoint and parallel to the user's viewpoint (e.g., depth is defined in a spherical or substantially spherical coordinate system where the origin of the viewpoint is at the center of a sphere extending outward from the user's head). In some embodiments, depth is defined relative to a user interface container (e.g., a window or application in which applications and / or system content are displayed), where the user interface container has a height and / or width, and depth is a dimension orthogonal to the height and / or width of the user interface container. In some embodiments, where depth is defined relative to a user interface container, when the container is placed in a three-dimensional environment or is initially displayed (e.g., such that the depth dimension of the container extends outward away from the user or the user's viewpoint), the height and / or width of the container is generally orthogonal or substantially orthogonal to a line extending from a user-based position (e.g., the user's viewpoint or the user's position) to the user interface container (e.g., the center of the user interface container or another feature point of the user interface container). In some embodiments, where depth is defined relative to a user interface container, the depth of an object relative to the user interface container refers to the positioning of the object along the depth dimension of the user interface container. In some embodiments, multiple different containers may have different depth dimensions (e.g., different depth dimensions extending away from the user or the user's viewpoint in different directions and / or from different starting points).In some embodiments, when depth is defined relative to a user interface container, the direction of the depth dimension remains constant for the user interface container as the position of the user interface container, the user, and / or the user's viewpoint changes (e.g., or when multiple different viewers are viewing the same container in a three-dimensional environment, such as during an in-person collaboration session and / or when multiple participants are in a real-time communication session with shared virtual content that includes the container). In some embodiments, for curved containers (e.g., including containers with curved surfaces or curved content areas), the depth dimension optionally extends into the surface of the curved container. In some cases, z separation (e.g., the separation of two objects in the depth dimension), z height (e.g., the distance of one object from another in the depth dimension), z positioning (e.g., the positioning of an object in the depth dimension), z depth (e.g., the positioning of an object in the depth dimension), or simulated z dimension (e.g., depth used as a dimension of an object, a dimension of an environment, a direction in space, and / or a direction in simulated space) is used to refer to the concept of depth as described above.

[0191] In some embodiments, a user can optionally use one or both hands to interact with virtual objects in a three-dimensional environment as if the virtual objects were real objects in the physical environment. For example, as described above, one or more sensors of the computer system can optionally capture one or both of the user's hands and display representations of the user's hands in the three-dimensional environment (e.g., in a manner similar to displaying real-world objects in a three-dimensional environment as described above). Alternatively, in some embodiments, the user's hands can be visible via the display generation component, due to the transparency / translucency of a portion of the user interface being displayed by the display generation component, or due to the projection of the user interface onto a transparent / translucent surface, or onto the user's eyes or into the user's field of view. Thus, in some embodiments, the user's hands are displayed at corresponding locations in the three-dimensional environment and are perceived as if they were objects in the three-dimensional environment. These objects can interact with virtual objects in the three-dimensional environment as if they were physical objects in the physical environment. In some embodiments, the computer system can update the display of the representation of the user's hands in the three-dimensional environment in conjunction with the movement of the user's hands in the physical environment.

[0192] In some embodiments described below, the computer system is optionally capable of determining an "effective" distance between a physical object in the physical world and a virtual object in a three-dimensional environment, for example, to determine whether the physical object is directly interacting with the virtual object (e.g., whether the hand is touching, grabbing, holding, etc., or is within a threshold distance of the virtual object). For example, a hand directly interacting with a virtual object optionally includes one or more of the following: a finger of a hand pressing a virtual button, a user's hand grabbing a virtual vase, two fingers of a user's hand coming together to pinch / hold the user interface of an application, and any other type of interaction described herein. For example, when determining whether a user is interacting with a virtual object and / or how the user is interacting with the virtual object, the computer system optionally determines the distance between the user's hand and the virtual object. In some embodiments, the computer system determines the distance between the user's hand and the virtual object by determining the distance between the position of the hand in the three-dimensional environment and the position of the virtual object of interest in the three-dimensional environment. For example, if the user's hand or hands are located at a specific location in the physical world, the computer system optionally captures the hand or hands and displays the hand or hands at a specific corresponding location in the three-dimensional environment (e.g., the location where the hand would be displayed in the three-dimensional environment if the hand were a virtual hand rather than a physical hand). The location of the hand in the three-dimensional environment is optionally compared to the location of the virtual object of interest in the three-dimensional environment to determine the distance between the user's hand or hands and the virtual object. In some embodiments, the computer system optionally determines the distance between the physical object and the virtual object by comparing the locations in the physical world (e.g., rather than comparing the locations in the three-dimensional environment). For example, when determining the distance between the user's hand or hands and the virtual object, the computer system optionally determines the corresponding location of the virtual object in the physical world (e.g., the location where the virtual object would be located in the physical world if the virtual object were a physical object rather than a virtual object), and then determines the distance between the corresponding physical location and the user's hand or hands. In some embodiments, the same technique is optionally used to determine the distance between any physical object and any virtual object. Thus, as described herein, when determining whether a physical object is in contact with a virtual object or whether a physical object is within a threshold distance of a virtual object, the computer system optionally executes any of the techniques described above to map the position of the physical object to a three-dimensional environment and / or map the position of the virtual object to the physical environment.

[0193] In some embodiments, the same or similar techniques are used to determine where and what the user's gaze is directed to, and / or where and what the physical stylus held by the user is pointed to. For example, if the user's gaze is directed to a particular location in the physical environment, the computer system optionally determines a corresponding location in the three-dimensional environment (e.g., a virtual location of the gaze), and if a virtual object is located at the corresponding virtual location, the computer system optionally determines that the user's gaze is directed to the virtual object. Similarly, the computer system is optionally able to determine the direction in which the stylus is pointing in the physical environment based on the orientation of the physical stylus. In some embodiments, based on this determination, the computer system determines a corresponding virtual location in the three-dimensional environment that corresponds to the location in the physical environment that the stylus is pointing to, and optionally determines that the stylus is pointing to the corresponding virtual location in the three-dimensional environment.

[0194] Similarly, the embodiments described herein may refer to the position of a user (e.g., a user of a computer system) in a three-dimensional environment and / or the position of a computer system in a three-dimensional environment. In some embodiments, the user of the computer system is holding, wearing, or otherwise located at or near the computer system. Thus, in some embodiments, the position of the computer system serves as a proxy for the user's position. In some embodiments, the position of the computer system and / or the user in the physical environment corresponds to a corresponding position in the three-dimensional environment. For example, the position of the computer system will be a position in the physical environment (and its corresponding position in the three-dimensional environment) such that if a user stood at that position, facing the corresponding portion of the physical environment visible via the display generation component, the user would see objects in the physical environment from that position in the same position, orientation, and / or size (e.g., in absolute terms and / or relative to each other) as the objects displayed by or visible in the three-dimensional environment by the display generation component of the computer system. Similarly, if the virtual objects displayed in the three-dimensional environment are physical objects in the physical environment (e.g., physical objects placed at the same location in the physical environment as the virtual objects are placed in the three-dimensional environment, and physical objects that have the same size and orientation in the physical environment as they do in the three-dimensional environment), then the position of the computer system and / or user is the position from which the user would see the virtual objects in the physical environment at the same location, orientation, and / or size (e.g., in an absolute sense and / or relative to each other and real-world objects) as the virtual objects displayed in the three-dimensional environment by the display generation components of the computer system.

[0195] In this disclosure, various input methods are described with respect to interaction with a computer system. When an example is provided using one input device or input method, and another example is provided using another input device or input method, it should be understood that each example is compatible with and optionally utilizes the input device or input method described with respect to the other example. Similarly, various output methods are described with respect to interaction with a computer system. When an example is provided using one output device or output method, and another example is provided using another output device or output method, it should be understood that each example is compatible with and optionally utilizes the output device or output method described with respect to the other example. Similarly, various methods are described with respect to interaction with a virtual environment or a mixed reality environment through a computer system. When an example is provided using interaction with a virtual environment, and another example is provided using a mixed reality environment, it should be understood that each example is compatible with and optionally utilizes the methods described with respect to the other example. Therefore, this disclosure discloses embodiments that are combinations of features from multiple examples, without necessarily listing all features of the embodiments in detail in the description of each example embodiment.

[0196] User interface and associated processes Attention is now turned to embodiments of a user interface ("UI") and associated processes that may be implemented on a computer system (such as a portable multifunction device or a head mounted device) in communication with one or more display generating components and one or more output devices.

[0197] 7A-7H illustrate examples of providing feedback related to device positioning adjustments. Figure 8 FIG. 7A to FIG. 7H are flowcharts of an exemplary method 800 for providing feedback related to device positioning adjustments. The user interfaces in FIG. 7A to FIG. 7H are used to illustrate the process described below, including Figure 8 in the process.

[0198] FIG7A depicts an electronic device 700 that is a smartwatch including a touch-sensitive display 702, a rotatable and depressible input mechanism 704a, and a button 704b. In some embodiments described below, the electronic device 700 is a smartwatch. In some embodiments, the user interface displayed by the electronic device 700 is implemented on an HMD X700. In FIG7A through FIG7H , the HMD X700 is represented by dashed lines to indicate that the user interface displayed by the electronic device 700 may also be implemented on the HMD X700. In some embodiments, a similar user interface may be implemented on a different electronic device, such as a smartphone, a tablet, a wearable device, a head-mounted system (e.g., a headset), and / or other computer systems that include one or more display devices (e.g., a display screen and / or a projection device) and / or communicate with one or more display devices. The electronic device 700 is a computer system (e.g., Figure 1A Computer system 101 in FIG.

[0199] 7A , the electronic device 700 and / or HMD X700 is in a low-power, inactive, and / or dormant state, in which content is not displayed via the display 702. At 7A , the electronic device 700 and / or HMD X700 detects user input 706. In the depicted embodiment, the user input 706 is a press input via a rotatable and depressible input mechanism 704 a. However, in some embodiments, the user input 706 is a different type of input, such as a gesture or other action taken by the user. For example, in some embodiments, the electronic device 700 is a head-mounted system (e.g., HMD X700), and detecting user input 706 includes, for example, detecting that the user is and / or has placed the electronic device 700 and / or HMD X700 on his or her head, detecting gestures while wearing the electronic device 700 and / or HMD X700, detecting the pressing of a button while wearing the electronic device 700 and / or HMD X700, detecting rotation of a rotatable input mechanism while wearing the electronic device 700 and / or HMD X700, detecting gaze-based gestures (e.g., detecting that the user is looking at an object and / or moving his or her gaze in a particular way), and / or any combination of the foregoing.

[0200] 7B , in response to detecting user input 706, the electronic device 700 and / or HMD X700 transitions from a low-power, inactive, and / or dormant state to an active state in which the electronic device 700 and / or HMD X700 displays content (e.g., a normal power state, a non-low-power state, an activated state, and / or a wake state) via the display 702. In FIG7B , the electronic device 700 and / or HMD X700 detects (e.g., via one or more sensors) that the physical positioning of the electronic device 700 and / or HMD X700 satisfies one or more error conditions (e.g., is not properly positioned, is not correctly positioned, and / or the electronic device 700 and / or HMD X700 should be moved (e.g., so that the electronic device 700 and / or HMD X700 operate properly and / or optimally)). In some embodiments, the electronic device 700 and / or the HMD X700 detects that the physical positioning of the electronic device 700 and / or the HMD X700 satisfies one or more error conditions relative to a part of the body of a user (e.g., a user who is using and / or wearing the electronic device 700 and / or the HMD X700) (e.g., relative to the user's head, the user's face, and / or a part of the user's face) (e.g., not properly positioned relative to the part of the user's body, not correctly positioned relative to the part of the user's body, and / or the electronic device 700 and / or the HMD X700 should be moved relative to the part of the user's body). For example, in some embodiments, the electronic device 700 is a head-mounted system (e.g., the HMD X700), and the electronic device 700 and / or the HMD X700 detects that at least a part of the electronic device 700 and / or the HMD X700 is not properly positioned relative to the user's head and / or face (e.g., should be moved relative to the user's head and / or face). In some embodiments, the electronic device 700 and / or HMD X700 detects that at least a portion of the electronic device 700 and / or HMD X700 is not properly positioned relative to the user's face and / or eyes, for example, for accurate gaze-based tracking (e.g., for gaze-based user input).

[0201] In the depicted embodiment, in response to user input 706, and based on a determination that the electronic device 700 satisfies one or more error conditions (e.g., relative to a portion of the user's body), the electronic device 700 and / or HMD X700 displays, via the display 702, a user interface 707 overlaid on a three-dimensional environment 708. In some embodiments, when the electronic device 700 and / or HMD X700 detects that the electronic device 700 does not satisfy the one or more error conditions (e.g., relative to at least a portion of the user's body) (e.g., the electronic device 700 and / or HMD X700 is properly positioned and / or the electronic device 700 and / or HMD X700 does not need to be moved (e.g., in order for the electronic device 700 and / or HMD X700 to operate properly and / or optimally), the electronic device 700 and / or HMD X700 forgoes display of the user interface 707 (e.g., displays a different user interface overlaid on the three-dimensional environment 708). In some embodiments, the user interface 707 is an extended reality user interface overlaid on the three-dimensional environment 708. In the depicted embodiment, three-dimensional environment 708 includes objects 708a, 708b. In some embodiments, three-dimensional environment 708 is displayed by a display (as depicted in FIG. 7B ). In some embodiments, three-dimensional environment 708 includes a virtual environment or images (or videos) of a physical environment captured (e.g., in 3D) by one or more cameras (e.g., one or more cameras that are part of and / or in communication with electronic device 700 and / or HMD X700). In some embodiments, three-dimensional environment 708 is visible to a user behind user interface 707 but is not displayed by a display. For example, in some embodiments, three-dimensional environment 708 is a physical environment that includes physical objects 708a, 708b and is visible to a user behind user interface 707 (e.g., through a transparent display) but is not displayed by a display.

[0202] In FIG7B , the electronic device 700 and / or HMD X700 determines that the electronic device 700 and / or HMD X700 should be moved to the left relative to a portion of a user's body (e.g., the user wearing the electronic device 700 and / or HMD X700). In response to this determination, the user interface 707 includes a prompt 710 instructing the user to move the electronic device 700 and / or HMD X700 "slightly to the left." The user interface 707 also includes an adjustment instruction 712, which includes objects 712a and 712b. Object 712a represents the current position of the electronic device 700 and / or HMD X700, and object 712b represents the target position (or destination position) for the electronic device 700 and / or HMD X700. The position of object 712a relative to object 712b indicates the direction in which the user should move the electronic device 700 and / or HMD X700. The user interface 707 also includes an arrow 712 c indicating that the user should move the electronic device 700 and / or the HMD X700 to the left (e.g., relative to a portion of the user's body). Furthermore, in FIG7B , in response to determining that the electronic device 700 and / or the HMD X700 should be moved to the left relative to a portion of the user's body, the electronic device 700 and / or the HMD X700 outputs an audio output 714-1 on the left side of the electronic device 700 and / or the HMD X700 (e.g., not on the right side of the electronic device 700 and / or the HMD X700), and also outputs a haptic (e.g., tactile) output 716-1 on the left side of the electronic device 700 and / or the HMD X700 (e.g., not on the right side of the electronic device 700 and / or the HMD X700).

[0203] In FIG7C , the electronic device 700 and / or HMD X700 detects that the electronic device 700 and / or HMD X700 has moved slightly to the left (e.g., relative to at least a portion of the user's body (e.g., relative to the user's head and / or face)). In response to detecting that the electronic device 700 and / or HMD X700 has moved to the left, the electronic device 700 and / or HMD X700 displays object 712a as moved to the left, closer to object 712b. In some embodiments, object 712a moves to the left in conjunction with the detection of the electronic device 700 and / or HMD X700 moving to the left. In some embodiments, the amount of leftward movement of object 712a is based on the amount of leftward movement detected by the electronic device 700 and / or HMD X700. However, the electronic device 700 and / or HMD X700 still needs to move further to the left, and therefore, object 712a remains positioned to the right of object 712b. In addition, based on determining that the electronic device 700 and / or HMD X700 still needs to move further to the left, prompt 710 continues to command the user to move the device to the left, and the electronic device 700 and / or HMD X700 outputs an audio output 714-2 on the left side of the electronic device 700 (for example, not on the right side of the electronic device 700 and / or HMD X700), and outputs a tactile (for example, haptic) output 716-2 on the left side of the electronic device 700 and / or HMD X700 (for example, not on the right side of the electronic device 700 and / or HMD X700). In some embodiments, in Figure 7C, based on determining that the electronic device 700 and / or HMD X700 is closer to its target position than it was in Figure 7B, the audio output 714-2 has a different volume (for example, a lower volume or a higher volume) than the audio output 714-1, and / or the tactile output 716-2 has a different magnitude (for example, a smaller magnitude or a larger magnitude) than the tactile output 716-1.

[0204] At 7D1, the electronic device 700 and / or HMD X700 detects that the electronic device 700 and / or HMD X700 has moved further to the left (e.g., relative to at least a portion of the user's body (e.g., relative to the user's head and / or face)), but is now too far to the left. Therefore, the electronic device 700 and / or HMD X700 determines that the electronic device 700 and / or HMD X700 should now move to the right. In response to determining that the electronic device 700 and / or HMD X700 should move to the right, the electronic device 700 and / or HMD X700 updates the display of prompt 710 to instruct the user to move the electronic device 700 and / or HMD X700 to the right, and also updates the display of object 712a, which now appears to the left of object 712b, along with object 712c indicating that the electronic device 700 and / or HMD X700 should move to the right. In addition, in response to this determination, the electronic device 700 and / or HMD X700 now outputs the audio output 714-3 and the tactile (e.g., haptic) output 716-3 to the right side of the electronic device 700 and / or HMD X700 (e.g., not on the left side of the electronic device 700 and / or HMD X700). In some embodiments, in Figure 7D1, based on determining that the electronic device 700 and / or HMD X700 is further away from its target location than it was in Figure 7C, the audio output 714-3 has a different volume (e.g., a lower volume or a higher volume) than the audio output 714-2, and / or the tactile output 716-3 has a different magnitude (e.g., a smaller magnitude or a larger magnitude) than the tactile output 716-2.

[0205] In some embodiments, the techniques and user interfaces described in FIG. 7A through FIG. 7H are provided by Figures 1A to 1P One or more of the devices described may be provided. For example, Figure 7D2 An embodiment is illustrated in which a cue 710 (e.g., as described in Figures 7B through 7D1) is displayed on a display module X702 of a head-mounted device (HMD) X700. In some embodiments, the device X700 includes a pair of display modules that provide stereoscopic content to different eyes of the same user. For example, the HMD X700 includes a display module X702 that provides content to the user's left eye and a second display module that provides content to the user's right eye. In some embodiments, the second display module displays a slightly different image than the display module X702 to create the illusion of stereoscopic depth.

[0206] exist Figure 7D2At , HMD X700 detects that HMD X700 has moved further to the left (e.g., relative to at least a portion of the user's body (e.g., relative to the user's head and / or face)), but is now too far to the left. Therefore, HMD X700 determines that HMD X700 should now move to the right. In response to determining that HMD X700 should move to the right, HMD X700 updates the display of prompt 710 to command the user to move HMD X700 to the right, and also updates the display of object 712a, which now appears to the left of object 712b, along with object 712c indicating that HMD X700 should move to the right. Furthermore, in response to this determination, HMD X700 now outputs audio output X714-3 and haptic (e.g., touch) output X716-3 to the right side of HMD X700 (e.g., not on the left side of HMD X700). In some embodiments, at Figure 7D2 7C , based on determining that HMD X700 is further from its target location than it is in FIG. 7C , audio output X 714-3 has a different volume (e.g., a lower volume or a higher volume) than audio output 714-2, and / or tactile output X 716-3 has a different magnitude (e.g., a smaller magnitude or a larger magnitude) than tactile output 716-2.

[0207] Figure 1B to Figure 1PAny of the features, components, and / or parts shown (including their arrangements and configurations) may be included, alone or in any combination, in HMD X700. For example, in some embodiments, HMD X700 includes any of the features, components, and / or parts of HMDs 1-100, 1-200, 3-100, 6-100, 6-200, 6-300, 6-400, 11.1.1-100, and / or 11.1.2-100, alone or in any combination. In some embodiments, the display module X702 includes, alone or in any combination, a display unit 1-102, a display unit 1-202, a display unit 1-306, a display unit 1-406, a display generation component 120, display screens 1-122a-b, a first rear display screen 1-322a and a second rear display screen 1-322b, a display 11.3.2-104, a first display component 1-120a and a second display component 1-120b, a display component 1-320, and a display component 1-421. , the first display subassembly 1-420a and the second display subassembly 1-420b, the display assembly 3-108, the display assembly 11.3.2-204, the first optical module 11.1.1-104a and the second optical module 11.1.1-104b, the optical module 11.3.2-100, the optical module 11.3.2-200, the double convex lens array 3-110, any of the characteristic parts, components and / or parts of the display area or display area 6-232 and / or the display / display area 6-334. In some embodiments, the HMD X700 includes sensors including, individually or in any combination, any of the features, components, and / or parts of sensor 190, sensor 306, image sensor 314, image sensor 404, sensor assembly 1-356, sensor assembly 1-456, sensor system 6-102, sensor system 6-202, sensor 6-203, sensor system 6-302, sensor 6-303, sensor system 6-402, and / or any of sensors 11.1.2-110a-f. In some embodiments, the HMD X700 includes one or more input devices including, individually or in any combination, any of the features, components, and / or parts of first button 1-128, button 11.1.1-114, second button 1-132, and / or any of dial or button 1-328. In some embodiments, HMD X700 includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback (e.g., audio output X714-3), which is optionally generated based on detected events and / or user input detected by HMD X700.

[0208] At Figure 7E , the electronic device 700 and / or HMD X700 detects that it has moved to the right (e.g., relative to at least a portion of the user's body (e.g., relative to the user's head and / or face)). In response to detecting that the electronic device 700 and / or HMD X700 has moved to the right, the electronic device 700 and / or HMD X700 displays object 712a moving further to the right. However, the electronic device 700 and / or HMD X700 detects that it should still move slightly further to the right. Therefore, the prompt 710 continues to state that the device should move to the right, object 712a remains slightly to the left of object 712b, and the electronic device 700 and / or HMD X700 outputs audio output 714-4 and tactile output 716-4 to the right side of the electronic device 700 and / or HMD X700. In some embodiments, in Figure 7E , based on determining that the electronic device 700 is further to the right than it was in Figures 7D and / or 7D , the prompt 710 may be used to display the object 712a. Figure 7D2 714-4 has a different volume (e.g., a lower volume or a higher volume) than audio output 714-3 and / or X714-3, and / or tactile output 716-4 has a different magnitude (e.g., a smaller magnitude or a larger magnitude) than tactile output 716-3 and / or X716-3.

[0209] 7F , the electronic device 700 and / or HMD X700 detects that the electronic device 700 and / or HMD X700 has moved further to the right and is now in its target position (e.g., relative to at least a portion of the user's body (e.g., relative to the user's head and / or face)) such that the electronic device 700 and / or HMD X700 no longer meets the one or more error criteria. In response to determining that the electronic device 700 and / or HMD X700 no longer meets the one or more error criteria, the electronic device 700 and / or HMD X700 ceases display of the user interface 707 and, optionally, displays a prompt 718 indicating that the electronic device 700 and / or HMD X700 no longer meets the one or more error criteria (e.g., indicating that the electronic device 700 and / or HMD X700 is correctly positioned (e.g., relative to at least a portion of the user's body (e.g., relative to the user's head and / or face))). In addition, in response to determining that the electronic device 700 and / or HMD X700 no longer meets one or more error criteria, the electronic device 700 outputs an audio output 714-5 and a tactile output 716-5 of the electronic device 700 and / or HMD X700 (e.g., on both sides, on all sides, and / or on multiple sides). In some embodiments, the audio output 714-5 is different from (e.g., is a different sound from) the audio outputs 714-1 to 714-4. In some embodiments, the tactile output 716-5 is different from (e.g., is a different vibration pattern from) the tactile outputs 716-1 to 716-4.

[0210] While the depicted examples have shown example scenarios in which the user interface 707 directs the user to move the electronic device 700 and / or the HMD X700 (e.g., left, right, up, and / or down), in some embodiments, the user interface 707 prompts the user to change one or more components of the electronic device 700 and / or the HMD X700. For example, in some embodiments, the electronic device 700 is a head-mounted system (e.g., the HMD X700) that includes an optical seal component and / or a headband component, and the user interface 707 instructs the user that the user should change the optical seal component (e.g., from a first size and / or shape to a second size and / or shape) and / or the headband component (e.g., from a first size and / or shape to a second size and / or shape). In some embodiments, changing the light sealing component (e.g., from a first size and / or shape to a second size and / or shape) and / or the headband component (e.g., from a first size and / or shape to a second size and / or shape) causes at least a portion of the electronic device 700 and / or HMD X700 to move further away from and / or closer to the user's body (e.g., head and / or face). In some embodiments, the light sealing component is a physical component that fits between the user's face and the computer system, display device, and / or one or more display generating components to block light (e.g., some light and / or all light) (e.g., external light and / or light not output by the computer system, display device, and / or one or more display generating components) from reaching the user's eyes. For example, in some embodiments, the light sealing component forms a seal around the user's eyes so that the user can see the one or more display components without external light interfering with the user's viewing of the one or more display components. In some embodiments, when the electronic device 700 and / or HMD X700 determines that the optical seal does not fit the user's face properly and / or the optical seal allows greater than a threshold amount of light to enter an area (e.g., an area between the user's eyes and one or more display components) (e.g., greater than a threshold amount of light is detected by one or more sensors of the computer system), the user is commanded to change the optical seal.

[0211] In some embodiments, even if the electronic device 700 and / or HMD X700 meets one or more error conditions, when the electronic device 700 and / or HMD X700 is displaying certain types of content and / or when the electronic device 700 and / or HMD X700 is operating in a specific state, the electronic device 700 and / or HMD X700 abandons displaying the user interface 707. For example, in Figure 7G, the electronic device 700 and / or HMD X700 displays a phone call user interface 720, which indicates that the electronic device 700 is currently participating in an active phone call. The phone call user interface 720 includes a contact name 722a, a phone call duration 722b, a mute button 722c, an options button 722e, and an end call button 722d. In FIG7G , the electronic device 700 and / or HMD X700 detects that the electronic device 700 and / or HMD X700 satisfies one or more error conditions (e.g., the electronic device 700 and / or HMD X700 is not properly positioned (e.g., relative to at least a portion of the user's body)). However, in order not to interrupt the user's experience, the electronic device 700 and / or HMD X700 abandons displaying the user interface 707 while the electronic device 700 and / or HMD X700 is engaged in a phone call and / or while the electronic device 700 and / or HMD X700 is displaying the user interface 720. In some embodiments, the electronic device 700 and / or HMD X700 abandons displaying the user interface 707 when the electronic device 700 and / or HMD X700 is displaying a certain type of content (e.g., immersive content and / or content that occupies a threshold amount of the display 702 (e.g., a full-screen video or other user interface that occupies a threshold amount of the display (e.g., 25% of the display, 50% of the display, 75% of the display, 90% of the display, and / or 95% of the display)) and / or is operating in a certain state (e.g., participating in an active communication session and / or displaying immersive content).

[0212] At 7G , the electronic device 700 and / or HMD X700 detects user input 724 corresponding to selection of the end call button 722 d, thereby ending the phone call. In the depicted embodiment, the user input 724 is a touch input via the touch-sensitive display 702. However, in some embodiments, the user input 724 is a different type of input, such as a gesture or other action taken by the user. For example, in some embodiments, the electronic device 700 is a head-mounted system (e.g., HMD X70), and detecting the user input 724 includes, for example, detecting a user performing a gesture (e.g., an air gesture) while wearing the electronic device 700 and / or HMD X700, detecting a button press while wearing the electronic device 700 and / or HMD X700, detecting a rotation of a rotatable input mechanism while wearing the electronic device 700 and / or HMD X700, detecting a gaze-based gesture (e.g., detecting that the user is looking at an object and / or moving their gaze in a particular manner), and / or any combination of the foregoing. At FIG. 7H , in response to detecting user input 724, the electronic device 700 and / or HMD X700 ceases display of the phone call user interface 720 and, based on a determination that the electronic device 700 and / or HMD X700 meets one or more error criteria and that the electronic device 700 and / or HMD X700 is no longer displaying the user interface 720 and / or is no longer involved in an active phone call, the electronic device and / or HMD X700 displays the user interface 707.

[0213] In FIG7H , user interface 707 indicates that the electronic device 700 and / or HMD X700 has determined that the electronic device 700 and / or HMD X700 should be moved to the left (e.g., relative to at least a portion of the user's body), similar to the technique of FIG7B . In response to this determination, user interface 707 includes prompt 710 instructing the user to move the electronic device 700 and / or HMD X700 "slightly to the left." User interface 707 also includes adjustment instructions 712, which include objects 712a and 712b. Object 712a represents the current positioning of the electronic device 700 and / or HMD X700, and object 712b represents the target positioning (or destination positioning) for the electronic device 700 and / or HMD X700. The positioning of object 712a relative to object 712b indicates the direction in which the user should move the electronic device 700 and / or HMD X700. The user interface 707 also includes an arrow 712c indicating that the user should move the electronic device 700 and / or HMD X700 to the left (e.g., relative to a portion of the user's body). Furthermore, in FIG7H , in response to determining that the electronic device 700 and / or HMD X700 should be moved to the left relative to a portion of the user's body, the electronic device 700 and / or HMD X700 outputs an audio output 714-6 on the left side of the electronic device 700 and / or HMD X700 (e.g., not on the right side of the electronic device 700 and / or HMD X700), and also outputs a haptic (e.g., tactile) output 716-6 on the left side of the electronic device 700 and / or HMD X700 (e.g., not on the right side of the electronic device 700 and / or HMD X700). As described above, in some embodiments, the object 712a moves in conjunction with the electronic device 700 and / or HMD X700 detecting movement of the electronic device 700 and / or HMD X700.

[0214] Reference below about Figure 8 The described method 800 provides additional description with respect to Figures 7A through 7H.

[0215] In some embodiments, Figure 8 is a flow chart of an exemplary method 800 for providing feedback related to device positioning adjustments. In some embodiments, the method 800 is performed on a computer system (e.g., Figure 1A , 700 and / or X700) is executed at a computer system 101 that is associated with one or more display generation components (e.g., Figure 1A 、 Figure 3 and Figure 4, 702 and / or display generation component 120 in X702) (e.g., a heads-up display, a display, a touch screen, a projector, a visual output device, a 3D display, a display having at least a portion that is transparent or translucent onto which an image can be projected (e.g., a see-through display), a projector, a heads-up display, and / or a display controller) and one or more input devices (e.g., 130, 140, 206, 702, 704a, 704b) (e.g., a touch-sensitive surface (e.g., a touch-sensitive display); a mouse; a keyboard; a remote control; a visual input device (e.g., one or more cameras (e.g., an infrared camera, a depth camera, a visible light camera, and / or a gaze tracking camera)); an audio input device; a biometric sensor (e.g., a fingerprint sensor, a facial identification sensor, a gaze tracking sensor, and / or an iris identification sensor) and / or one or more mechanical input devices (e.g., a depressible input mechanism; a button; a rotatable input mechanism; a crown; and / or a dial)). In some embodiments, method 800 is performed by storing in a non-transitory (or transitory) computer-readable storage medium and executed by one or more processors of a computer system (such as one or more processors 202 of computer system 101) (e.g., Figure 1A Some operations in method 800 may be optionally combined, and / or the order of some operations may be optionally changed.

[0216] In some embodiments, the computer system (e.g., 700 and / or X700) detects (802) a positioning of a portion of the computer system relative to a face of a user (e.g., relative to one or more features of the user's face (e.g., relative to the user's eyes and / or relative to the user's nose)) (in some embodiments, the computer system is worn on the user's face). In some embodiments, detecting the positioning of the portion of the computer system relative to the user's face is performed in response to detecting that the computer system is worn on the user's face. In response to detecting the positioning of the portion of the computer system relative to the user's face (804), and in accordance with determining that the computer system satisfies corresponding criteria while the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions (e.g., the positioning of the portion of the computer system relative to the user's face is determined to be faulty) (e.g., the computer system and / or the portion of the computer system is too far to the left of the user's face, the computer system and / or the portion of the computer system is too far to the right of the user's face, the computer system and / or the portion of the computer system is too high on the user's face, the computer system and / or the portion of the computer system is too low on the user's face, the computer system and / or the portion of the computer system is too close to the user's face, and / or the computer system and / or the portion of the computer system is too far from the user's face), wherein the corresponding criteria include that the computer system is operating in a corresponding context to satisfy the corresponding criteria (e.g., the computer system is not displaying immersive content, the computer system is stationary, and / or the computer system is not being moved by the user) (e.g., the computer system 700 and / or the HMD 7A to 7F , but not the corresponding context of FIG. 7G ), the computer system outputs (808) a first alert (e.g., 707, 710, 712a, 712b, 712c, 714-1, 714-2, 714-3, X714-3, 714-4, 714-6, 716-1, 716-2, 716-3, X716-3, 716-4, and / or 716-6) (e.g., a tactile alert, an audio alert, and / or a visual alert) indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions (e.g., an alert prompting the user to adjust the positioning of the computer system and / or the portion of the computer system relative to the user's face and / or an alert prompting the user to replace and / or change one or more components of the computer system).In response to detecting the positioning of the portion of the computer system relative to the user's face (804) and in accordance with determining that the computer system does not satisfy corresponding criteria (e.g., in FIG. 7G ) (e.g., the computer system is displaying immersive content, the computer system is not stationary, and / or the computer system is being moved by the user), while the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions (810), the computer system forgoes (812) outputting the first alert (e.g., until device context criteria are met) (e.g., in FIG. 7G , the computer system 700 and / or HMD X 700 does not display the user interface 707 and / or does not output audio and / or haptic output indicating that the computer system 700 and / or HMD X 700 satisfies one or more error conditions).

[0217] In some embodiments, in response to detecting the positioning of the portion of the computer system relative to the user's face, and based on determining that the positioning of the portion of the computer system relative to the user's face does not satisfy one or more error conditions (e.g., the positioning of the portion of the computer system relative to the user's face is not determined to be faulty and / or is determined to be correct), the computer system forgoes outputting the first alert (e.g., Figure 7F).

[0218] In some embodiments, after abandoning outputting the first alert (e.g., Figure 7G) (e.g., after detecting that the computer system does not meet the corresponding standard and the positioning of the part of the computer system relative to the user's face meets one or more error conditions), and based on determining that the computer system meets the corresponding standard and the positioning of the part of the computer system relative to the user's face meets one or more error conditions, the computer system outputs the first alert (e.g., in Figure 7G, based on determining that the electronic device 700 and / or HMD X700 does not meet the corresponding standard, the electronic device 700 and / or HMD X700 abandons outputting the first alert, and in Figure 7H, based on determining that the computer system now meets the corresponding standard, the electronic device 700 and / or HMD X700 outputs the first alert).

[0219] Outputting an alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so provides visual feedback to the user regarding the status of the device (e.g., that the device has determined that the positioning of the computer system relative to the user's face satisfies one or more error conditions).

[0220] In some embodiments, after forgoing outputting the first alert based on a determination that the computer system does not meet the corresponding criteria and the positioning of the portion of the computer system relative to the user's face meets one or more error conditions (e.g., FIG. 7G ), and based on a determination that the computer system meets the corresponding criteria and the positioning of the portion of the computer system relative to the user's face meets one or more error conditions (e.g., FIG. 7H ), the computer system outputs the first alert indicating that the positioning of the portion of the computer system relative to the user's face meets the one or more error conditions (e.g., in FIG. 7G , based on a determination that the electronic device 700 and / or HMD X700 does not meet the corresponding criteria, the electronic device 700 and / or HMD X700 forgoes outputting the first alert, and in FIG. 7H , based on a determination that the computer system now meets the corresponding criteria, the electronic device 700 and / or HMD X700 outputs the first alert). Outputting the alert indicating that the positioning of the portion of the computer system relative to the user's face meets the one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends device battery life by enabling the user to use the system more quickly and efficiently. Additionally, doing so provides visual feedback to the user regarding the status of the device (eg, the device has determined that the positioning of the computer system relative to the user's face satisfies one or more error conditions).

[0221] In some embodiments, in response to detecting the positioning of the portion of the computer system relative to the user's face, and based on determining that the positioning of the portion of the computer system relative to the user's face does not satisfy one or more error conditions (e.g., determining that the positioning of the portion of the computer system relative to the user's face is correct; the computer system and / or the portion of the computer system is properly positioned relative to the user's face (e.g., on the user's face); and / or one or more metrics and / or sensor readings indicating the positioning of the computer system and / or the portion of the computer system relative to the user's face are within a predefined range of values), the computer system forgoes outputting the first alert (e.g., 707, 710, 712a, 712b, 712c, 714-1, 714-2, 714-3, X714-3, 714-4, 714-6, 716-1, 716-2, 716-3, X716-3, 716-4, and / or 716-6) (e.g., Figure 7F). Outputting an alert when the error condition is met and forgoing outputting the alert when the error condition is not met provides visual feedback to the user regarding the status of the device (eg, whether the error condition is met).

[0222] In some embodiments, outputting a first alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions includes: outputting an initial alert (e.g., 707, 714-1, and / or 716-1 in FIG. 7B ) (e.g., a visual initial alert and / or a non-visual (e.g., audio and / or tactile) initial alert) (e.g., an initial alert indicating a first magnitude and / or a first direction (e.g., a first magnitude and / or a first direction of movement required to correct the positioning of the portion of the computer system relative to the user's face)); detecting, via one or more input devices, a first movement of the portion of the computer system relative to the user's face when outputting the initial alert (e.g., when displaying the initial alert and / or when outputting the non-visual initial alert (e.g., audio and / or tactile output)). Figure 7D2 and / or from FIG. 7D1 to FIG. 7E ); and in response to detecting a first movement of the portion of the computer system relative to the user's face, outputting a modified alert (e.g., 707, 714-2, 716-2 in FIG. 7C , FIG. 7D1 and / or FIG. 7E ) that is different from the initial alert based on the first movement of the portion of the computer system relative to the user's face. Figure 7D2707, 714-3, X714-3, 716-3, X716-3, 707, 714-4 and / or 716-4 in FIG. 7E ) (e.g., a visual corrected alert and / or a non-visual (e.g., audio and / or tactile) corrected alert) (e.g., a corrected alert indicating a second magnitude and / or a second direction (e.g., a second magnitude different from the first magnitude and / or a second direction different from the first direction) (e.g., a second magnitude and / or a second direction of movement required to correct the positioning of the portion of the computer system relative to the user's face)). In some embodiments, outputting a corrected alert that is different from the initial alert includes updating and / or replacing the initial alert. In some embodiments, while outputting the revised alert, the computer system detects, via one or more input devices, a second movement of the portion of the computer system relative to the user's face; and in response to detecting the second movement of the portion of the computer system, the computer system outputs a second revised alert (e.g., a visual second revised alert and / or a non-visual (e.g., audio and / or tactile) second revised alert) that is different from the revised alert based on the second movement of the portion of the computer system relative to the user's face (e.g., a second revised alert indicating a third magnitude and / or third direction (e.g., a third magnitude different from the second magnitude and / or a third direction different from the second direction) (e.g., a third magnitude and / or third direction of movement required to correct the positioning of the portion of the computer system relative to the user's face)). Monitoring the positioning of the portion of the computer system relative to the user's face and providing continuous feedback enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends battery life of the device by enabling the user to use the system more quickly and efficiently.

[0223] In some embodiments, outputting a first alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions includes displaying, via one or more display generating components, a visual alert (e.g., 707, 710, 712a, 712b, and / or 712c) indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions (e.g., a visual alert commanding the user to move the computer system and / or the portion of the computer system (e.g., relative to the user's face); a visual alert commanding the user to move the computer system and / or the portion of the computer system in a first direction (e.g., relative to the user's face); a visual alert indicating an amount by which the user should move the computer system and / or the portion of the computer system (e.g., relative to the user's face); and / or a visual alert indicating that the user should replace one or more components of the computer system). In some embodiments, the visual alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions indicates a magnitude and / or direction corresponding to the one or more error conditions (e.g., a magnitude and / or direction to move the portion of the computer system (e.g., so as to cease satisfying one or more error conditions)). Displaying a visual alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so provides visual feedback to the user regarding the status of the device (e.g., that the device has determined that the positioning of the computer system relative to the user's face satisfies one or more error conditions).

[0224] In some embodiments, outputting a first alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions includes outputting a non-visual alert (e.g., 714-1 to 714-4, 716-1 to 716-4, 714-6, and / or 716-6) (e.g., an audio alert, a tactile alert, and / or a tactile alert) indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions (e.g., a non-visual alert indicating that the user should move the computer system and / or the portion of the computer system (e.g., relative to the user's face); a non-visual alert indicating that the user should move the computer system and / or the portion of the computer system in a particular direction (e.g., relative to the user's face); and a non-visual alert indicating that the user should move the computer system and / or the portion of the computer system in a particular direction (e.g., relative to the user's face). an audio output and / or a tactile output from a first direction to indicate that the user should move the computer system in the first direction, and / or an audio output and / or a tactile output from a second direction to indicate that the user should move the computer system in the second direction); a non-visual alert indicating that the user should move the computer system and / or the portion of the computer system by a first magnitude (e.g., relative to the user's face) (e.g., a louder audio output and / or a larger tactile output for a larger magnitude, and / or a quieter audio output and / or a smaller tactile output for a smaller magnitude); and / or a non-visual alert indicating that the user should replace one or more components of the computer system (e.g., an audio instruction to replace one or more components of the computer system). In some embodiments, the non-visual alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions indicates a magnitude and / or direction corresponding to the one or more error conditions (e.g., a magnitude and / or direction to move the portion of the computer system (e.g., so as to cease satisfying the one or more error conditions)). Outputting a non-visual alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions enhances system operability and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors). This additionally reduces power usage and extends the device's battery life by enabling the user to use the system more quickly and efficiently. Furthermore, this provides feedback to the user regarding the state of the device (e.g., the device has determined that the positioning of the computer system relative to the user's face satisfies one or more error conditions). Additionally, if an error makes a visual element more difficult to view, the non-visual alert provides instructions for not being affected by the error.

[0225] In some embodiments, outputting a first alert indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions includes: outputting an alert indicating that a light-sealing component of the computer system (e.g., a physical component (e.g., a physical component that fits between the user's face and the computer system, display device, and / or one or more display generating components) that blocks light (e.g., prevents light (e.g., some light and / or all light) (e.g., external light and / or light not output by the computer system, display device, and / or one or more display generating components)) from reaching the user's eyes) satisfies one or more light-sealing error conditions (e.g., an alert indicating that the light-sealing component of the computer system is not properly fitted to the user's face; an alert indicating that the light-sealing component of the computer system is allowing greater than a threshold amount of light to enter the computer system; and / or an alert indicating that greater than a threshold amount of light is detected by one or more sensors of the computer system) (e.g., prompt 710 and / or user interface 707 commanding the user to change the light-sealing component (e.g., from a first size and / or shape to a second size and / or shape)). In some embodiments, the one or more error conditions include a first condition that is satisfied when a threshold amount of light is detected by one or more sensors in communication with the computer system (e.g., one or more sensors indicating a fit of the light seal component relative to the user's face). Outputting an alert indicating that the light seal component of the computer system satisfies one or more light seal error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently.

[0226] In some embodiments, outputting a first alert (e.g., 707, 710, 712, 714-1, 714-2, 714-3, X714-3, 714-4, 714-6, 716-1, 716-2, 716-3, X716-3, 716-4, and / or 716-6) indicating that the positioning of the computer system relative to the user's face satisfies one or more error conditions includes outputting an alert indicating that the user's eyes are too close to or too far away from the portion of the computer system (e.g., the offset of the user's eyes relative to the portion of the computer system (e.g., the display generating component and / or the eyepiece) is not within a threshold range of distance and / or offset). Outputting an alert indicating that the user's eyes are too close to or too far away from the portion of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends battery life of the device by enabling the user to use the system more quickly and efficiently.

[0227] In some embodiments, the corresponding criteria include content type criteria that are satisfied when the computer system is not outputting a first type of content (e.g., in FIG. 7G , the electronic device 700 and / or HMD X700 is displaying an immersive user interface (e.g., which occupies greater than a threshold amount of the display), while in FIG. 7H , the electronic device 700 and / or HMD X700 has stopped displaying immersive content) (e.g., not outputting content and / or outputting a second type of content that is different from the first type) (e.g., the computer system is not displaying a first type of content (e.g., visual content corresponding to an immersive experience (e.g., a video; full-screen video; a game; a virtual reality game; and / or an active communication session (e.g., an active phone call or an active video conference))); and / or the computer system is not playing audio content corresponding to an immersive experience (e.g., audio content corresponding to a video; full-screen video; a game; a virtual reality game; and / or an active communication session (e.g., an active phone call or an active video conference))). Automatically outputting a first alert based on determining that the computer system is not outputting the first type of content allows these operations to be performed automatically without additional user input.

[0228] In some embodiments, the first type of content is immersive experience content (e.g., in FIG. 7G , the electronic device 700 and / or HMD X700 is displaying an immersive user interface (e.g., which occupies greater than a threshold amount of the display), while in FIG. 7H , the electronic device 700 and / or HMD X700 has stopped displaying the immersive content) (e.g., an immersive experience (e.g., a video; a full-screen video; a game; a virtual reality game; and / or an active communication session (e.g., an active phone call or an active video conference))). In some embodiments, the immersive experience content occupies greater than a threshold proportion of the user's field of view (e.g., greater than 50%, greater than 75%, and / or greater than 90%). In some embodiments, the immersive experience content cannot be displayed concurrently with other unrelated content and / or the concurrent display of other unrelated content (e.g., content generated by and / or related to applications other than the immersive experience content) is prevented (in some embodiments, except for certain predefined system user interface elements (e.g., operating system user interface elements), such as alerts, notifications, home UI, control center, dock). Automatically outputting the first alert based on determining that the computer system is not outputting immersive content and automatically suppressing the first alert when the computer system is outputting immersive content allow these operations to be performed automatically without additional user input.

[0229] In some embodiments, after forgoing outputting the first alert based on determining that the computer system does not meet the corresponding criteria while the positioning of the portion of the computer system relative to the user's face meets one or more error conditions, the computer system detects that the computer system has stopped outputting the first type of content (e.g., in FIG. 7G , the electronic device 700 and / or HMD X700 is displaying an immersive user interface (e.g., which occupies an amount of the display greater than a threshold), while in FIG. 7H , the electronic device 700 and / or HMD X700 has stopped displaying immersive content) (e.g., has transitioned from outputting the first type of content to no longer outputting the first type of content); and in response to detecting that the computer system has stopped outputting the first type of content, the computer system outputs the first alert (e.g., in FIG. 7H , the electronic device 700 and / or HMD X700 outputs the first alert (e.g., 707 , 710 , 712 , 714 - 6 , and / or 716 - 6 )). Automatically outputting the first alert once the first type of content is no longer being output allows these operations to be performed automatically without additional user input. Furthermore, doing so provides the user with instructions to correct the error as quickly as possible without interrupting the user experience, thereby improving the operability of the device.

[0230] In some embodiments, the corresponding criteria include a stability criterion that is satisfied when the computer system satisfies a stability criterion relative to the user's face (e.g., the computer system is moving less than a threshold amount relative to the user's face (e.g., at less than a threshold speed (e.g., 0.9 m / s, 0.1 m / s, 0.01 m / s, and / or 0.001 m / s), at less than a threshold acceleration (e.g., less than 1 m / s / s, less than 0.1 m / s / s, and / or less than 0.01 m / s / s), and / or less than a threshold magnitude (e.g., less than 5 cm, less than 1 cm, less than 0.5 cm, less than 0.1 cm, less than 0.05 cm, and / or less than 0.01 cm)) (e.g., in FIG. 7B , if the user is still moving the electronic device 700 and / or HMD X700 (e.g., the user is still placing the electronic device on his or her head), the electronic device 700 and / or HMD X700 The X700 will forgo display of the user interface 707 and / or output of the audio output 714-1 and / or tactile output 716-1. In some embodiments, determining that the computer system does not meet the corresponding criteria includes determining that the computer system does not meet the stability criteria relative to the user's face (e.g., the computer system is moving relative to the user's face by greater than a threshold amount (e.g., at greater than a threshold speed, with greater than a threshold acceleration, and / or greater than a threshold magnitude)). Outputting an alert indicating that the positioning of the portion of the computer system relative to the user's face meets one or more error conditions when it is determined that the computer system meets the stability criteria relative to the user's face enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently.

[0231] In some embodiments, the first alert includes a suggestion (e.g., instructions and / or indication) to replace one or more hardware components of the computer system with a different hardware component (e.g., a hardware component of the same type with a different size and / or shape) (e.g., a light seal component, a display generating component, an ear seal component, and / or a headband component) (e.g., the user interface 707 and / or prompt 710 includes instructions to replace one or more hardware components of the computer system). Outputting an alert suggesting that the user change one or more hardware components of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. In addition, doing so provides visual feedback to the user about the status of the device (e.g., the device has determined that one or more hardware components should be changed).

[0232] In some embodiments, the first alert includes a suggestion (e.g., instruction and / or direction) to change one or more settings of the computer system (e.g., an interpupillary distance setting and / or one or more display settings) (e.g., user interface 707 and / or prompt 710 includes instructions to change one or more settings of the computer system). Outputting an alert suggesting that the user change one or more settings of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. In addition, doing so provides visual feedback to the user about the status of the device (e.g., the device has determined that one or more settings should be changed).

[0233] In some embodiments, the first alert (e.g., 707, 710, 712, 712a, 712b, 712c, 714-1, 714-2, 714-3, X714-3, 714-4, 714-6, 716-1, 716-2, 716-3, X716-3, 716-4, and / or 716-6) includes a suggestion (e.g., instruction and / or direction) to move the portion of the computer system relative to the user's face (e.g., a suggestion to move the portion of the computer system right, left, up, and / or down). Outputting an alert suggesting that the user move the portion of the computer system relative to the user's face enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. In addition, doing so provides visual feedback to the user about the status of the device (e.g., the device has determined that the device should be moved relative to the user's face).

[0234] In some embodiments, aspects / operations of methods 800 and / or 1000 may be interchanged, replaced, and / or added between these methods. For example, in some embodiments, the computer system in method 800 is the computer system in method 1000. For the sake of brevity, these details are not repeated here.

In some embodiments, Figures 9A to 9G The described techniques and user interface are provided by Figures 1A to 1P In some embodiments, the electronic device 900 includes a pair of display modules that provide stereoscopic content to different eyes of the same user. For example, the electronic device 900 includes a display module 902 that provides content to the user's left eye and a second display module that provides content to the user's right eye. In some embodiments, the second display module displays a slightly different image than the display module 902 to create the illusion of stereoscopic depth.

In some embodiments, the mechanical input device 906a-906c includes, alone or in any combination, any of the features, components, and / or parts of first button 1-128, button 11.1.1-114, second button 1-132, and / or any of dial or button 1-328. In some embodiments, the electronic device 900 includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback, which is optionally generated based on detected events and / or user input detected by the electronic device 900. The electronic device 900 is a computer system (e.g., Figure 1A Computer system 101 in FIG.

[0238] exist Figure 9AAt 9:00, electronic device 900 displays, via display 902, a user interface 910 corresponding to a first application and a user interface 912 corresponding to a second application overlaid on a three-dimensional environment 908. In the depicted scene, the three-dimensional environment includes objects 908a and 908b. In some embodiments, three-dimensional environment 908 is displayed by a display (e.g., display 902). In some embodiments, three-dimensional environment 908 includes a virtual environment or an image (or video) of a physical environment captured by one or more cameras (e.g., one or more cameras as part of input sensors 904 and / or one or more external cameras). For example, in some embodiments, object 908a is a virtual object representing a physical object captured by one or more cameras and / or detected by one or more sensors; object 908b is a virtual object representing a second physical object captured by one or more cameras and / or detected by one or more sensors, and so on. In some embodiments, three-dimensional environment 908 is visible to the user through display 902 but is not displayed by the display. For example, in some embodiments, three-dimensional environment 908 is a physical environment visible to a user (eg, through one or more transparent displays (eg, 902 )) rather than displayed by a display (and, for example, objects 908a - 908b are physical objects).

[0239] In various depicted embodiments, the electronic device 900 is configured to detect one or more error conditions related to the positioning of the electronic device 900 relative to a portion of a user's body. For example, in some embodiments, the electronic device 900 is a head-mounted system, and the electronic device 900 is configured to detect one or more error conditions related to the positioning of the electronic device 900 relative to the user's face and / or one or more facial features of the user (e.g., the user's eyes and / or the user's nose). In some embodiments, a first set of error conditions and / or a first type of error condition results in a first type of alert, and a second set of error conditions and / or a second type of error condition results in a second type of alert that is different from the first type of alert. In some embodiments, the second set of error conditions and / or the second type of error condition is considered more serious, and the second type of alert is more difficult to dismiss than the first type of alert, and / or the second type of alert requires and / or demands more user attention.

[0240] exist Figure 9BAt , the electronic device 900 detects that the positioning of the electronic device 900 relative to the user's body (e.g., the user's face) satisfies a first set of error criteria corresponding to a first type of error condition. In some embodiments, the first type of error condition is considered less important or less severe. For example, in some embodiments, the first type of error condition includes determining that the electronic device 900 should be moved right, left, up, and / or down on the user's face. In some embodiments, the first type of error condition includes determining that the electronic device 900 should be moved closer to the user's face. In some embodiments, the electronic device 900 is moved closer to or farther away from the user's face by changing one or more components (e.g., hardware components) of the electronic device 900. For example, in some embodiments, the electronic device 900 is moved closer to or farther away from the user's face by changing the optical sealing component (e.g., optical seal 1-110 and / or optical seal 1-210) of the electronic device 900 to a different optical sealing component with a different physical size. Figure 9B At , based on determining that the positioning of the electronic device 900 satisfies a first set of error criteria corresponding to a first type of error condition, the electronic device 900 displays an alert 914 notifying the user that the positioning of the electronic device 900 satisfies one or more error conditions. In some embodiments, the alert 914 provides instructions to the user on how to correct and / or rectify the error condition. For example, the alert 914 instructs the user to move the electronic device 900 left, right, up, and / or down on the user's face. In some embodiments, the alert 914 instructs the user to change the light sealing component of the electronic device 900 to a different light sealing component.

[0241] In some embodiments, the alert 914 is displayed as an environmental lock object. Figure 9C At , the viewpoint of the electronic device 900 changes (e.g., based on movement of the user's head when the user wears the electronic device 900 on his or her head). The alert 914, being an environment-locked object, maintains its position within the three-dimensional environment 908 as the viewpoint of the electronic device 900 and / or the user's viewpoint changes. Figure 9D At , the electronic device 900 detects that the positioning of the electronic device 900 no longer meets the first set of error criteria relative to the part of the user's body. Figure 9D At , the user shifts the positioning of the electronic device 900 on his or her face so that it is now correctly positioned. In response to detecting that the positioning of the electronic device 900 no longer meets the first set of error criteria relative to the part of the user's body, the electronic device 900 stops displaying the alert 914.

[0242] exist Figure 9EAt , the electronic device 900 detects that the positioning of the electronic device 900 relative to the user's body (e.g., the user's face) satisfies a second set of error criteria corresponding to a second type of error condition. In some embodiments, the second type of error condition is considered more important or more severe than the first type of error condition. For example, in some embodiments, the second type of error condition includes determining that one or more components of the electronic device 900 are too close to one or more parts of the user's face (e.g., the display 902 is too close to the user's face, eyes, and / or nose). Figure 9E At, in response to detecting that the positioning of the electronic device 900 satisfies the second set of error conditions, the electronic device 900 displays an alert 916. In some embodiments, the alert 916 notifies the user that the positioning of the electronic device 900 satisfies the second set of error criteria. In some embodiments, the alert 916 instructs the user how to correct the error. For example, in some embodiments, the alert 916 instructs the user to change a component (e.g., a light seal component or other component) or the electronic device 900, and provides the user with a URL to order the component. In some embodiments, the alert 916 requires user input (e.g., on option 916a) to dismiss the alert 916, and the alert 916 is not dismissed automatically. Furthermore, in the depicted embodiment, the alert 916 is displayed as a viewpoint-locked object. Figure 9F At this point, the viewpoint of the electronic device 900 changes (e.g., based on the movement of the user's head when the user wears the electronic device 900 on his or her head). However, the alert 916, which is the viewpoint-locked object, remains in the same display position relative to the user's viewpoint. In some embodiments, one or more features of the electronic device 900 are unavailable while the alert 916 is displayed. For example, in some embodiments, the user cannot interact with the user interface window 910 or the user interface window 912 while the alert 916 is displayed. In some embodiments, when the Figure 9C When the alert 914 is displayed, one or more features of the electronic device remain available to the user. Figure 9C , when alert 914 is displayed, the user can still interact with window 910 and window 912.

[0243] In some embodiments, the electronic device 900 outputs different sets of alerts based on the operating state of the electronic device 900. For example, in some embodiments, the electronic device 900 can operate in an authorized user state or a guest state. In the guest state, the authorized user has allowed unauthorized users to use the electronic device 900 in the guest state, and the electronic device 900 provides access to fewer features and / or less content than when the electronic device 900 is operated in the authorized user state. In some embodiments, certain types of alerts are displayed identically in the authorized user state and the guest state. For example, in some embodiments, an alert commanding the user to move the device up, down, left, or right on the user's face is displayed in both operating states. However, in some embodiments, certain alerts are displayed differently in the two operating states. For example, in some embodiments, in the authorized user operating state, the electronic device 900 commands the user to change a physical component of the electronic device 900 and / or order a new physical component. However, in the guest operating state, the electronic device 900 does not command the user to order a new physical component, but instead notifies the user that the user's experience may be suboptimal due to one or more error conditions. In Figure 9G In the example embodiment, electronic device 900 is operating in the guest operating state and an indication 918 is displayed indicating that electronic device 900 is operating in the guest operating state. While in the guest operating state, electronic device 900 detects that the positioning of electronic device 900 relative to a portion of the user's body meets an error criterion. In response, electronic device 900 displays alert 920. In some embodiments, alert 920 is different from alert 920 and / or alert 916 based on a determination that electronic device 900 is operating in the guest operating state (rather than the authorized user operating state).

[0244] In some embodiments, Figure 10 is a flow chart of an exemplary method 1000 for providing feedback related to device positioning adjustments. In some embodiments, the method 1000 is performed on a computer system (e.g., Figure 1A The computer system 101 in the embodiment of the present invention and / or the electronic device 900) (e.g., a smart phone, a smart watch, a tablet, a laptop, a desktop computer, a wearable device and / or a head-mounted device) is executed at the computer system and one or more display generation components (e.g., 902) (e.g., Figure 1A 、 Figure 3 and Figure 4In some embodiments, method 1000 communicates with the display generation component 120 in the computer system (e.g., a visual output device, a 3D display, a display having at least a portion that is transparent or translucent onto which an image can be projected (e.g., a see-through display), a projector, a heads-up display, and / or a display controller) and one or more input devices (e.g., 902, 904, and / or 906a-906c) (e.g., a touch-sensitive surface (e.g., a touch-sensitive display); a mouse; a keyboard; a remote control; a visual input device (e.g., one or more cameras (e.g., an infrared camera, a depth camera, a visible light camera, and / or a gaze tracking camera)); an audio input device; a biometric sensor (e.g., a fingerprint sensor, a facial identification sensor, a gaze tracking sensor, and / or an iris identification sensor); and / or one or more mechanical input devices (e.g., a depressible input mechanism; a button; a rotatable input mechanism; a crown; and / or a dial)). In some embodiments, method 1000 communicates with one or more processors of a computer system (e.g., one or more processors 202 of computer system 101) (e.g., Figure 1A Some operations in method 1000 may be optionally combined, and / or the order of some operations may be optionally changed.

[0245] The computer system (e.g., 900) detects (1002) a positioning of a portion of the computer system (e.g., 900) relative to a portion of a body (e.g., face, eyes, or wrist) of a user (e.g., relative to one or more features of the user's face (e.g., relative to the user's eyes and / or relative to the user's nose)) (in some embodiments, the computer system is worn on the user's face) (in some embodiments, detecting the positioning of the computer system relative to the user's face is performed in response to detecting that the computer system is worn on the user's face).

[0246] In response to (1004) detecting a positioning of the computer system relative to a portion of a user's body (e.g., face, eye, or wrist), and based on determining that the positioning of the portion of the computer system relative to the portion of the user's body (e.g., face, eye, or wrist) satisfies a first set of error conditions (e.g., based on determining that the positioning of the portion of the computer system is too high, too low, too far to the left, and / or too far to the right relative to a target positioning of the portion of the computer system relative to the user's body (e.g., face) (e.g., relative to one or more features and / or a portion of the user's face); and / or based on determining that the positioning of the portion of the computer system is too far away from and / or too close to the user's body (e.g., face) (e.g., relative to one or more features and / or a portion of the user's face)) (e.g., the first set of error conditions (e.g., reduced gaze input accuracy and / or other input accuracy) that may result in reduced user input accuracy) and / or or a first set of error conditions representing a potential safety hazard to a user), the computer system (e.g., 900), via one or more display generating components (e.g., 902), displays (1006) a first alert (e.g., 916) indicating that positioning of the computer system relative to the portion of the user's body (e.g., face, eye, or wrist) satisfies the first set of error conditions (e.g., an alert notifying the user that user input may have reduced accuracy, an alert notifying the user of a potential safety hazard to the user, an alert prompting the user to adjust positioning of the computer system relative to the user's face, and / or an alert prompting the user to replace and / or change one or more components of the computer system), wherein the first alert prevents access to one or more features of the computer system until the first alert is dismissed (e.g., until the user performs one or more functions to dismiss the first alert and / or until the first set of error conditions is no longer satisfied).

[0247] In response to (1004) detecting a positioning of the computer system relative to a portion of a user's body (e.g., face, eye, or wrist), and based on determining that the positioning of the portion of the computer system relative to the portion of the user's body (e.g., face, eye, or wrist) satisfies a second set of error conditions that are different from the first set of error conditions (e.g., based on determining that the positioning of the portion of the computer system is too high, too low, too far to the left, and / or too far to the right of a target positioning of the portion of the computer system relative to the user's body (e.g., face) (e.g., relative to one or more features and / or a portion of the user's face); and / or based on determining that the positioning of the portion of the computer system is too far away from and / or too close to the user's body (e.g., face) (e.g., relative to one or more features and / or a portion of the user's face)), the second set of error conditions (e.g., that may result in reduced user input accuracy) are satisfied. , reduced gaze input accuracy and / or other input accuracy) and / or a second set of error conditions that do not pose a potential safety hazard to the user), the computer system (e.g., 900) displays (1008) via one or more display generating components a second alert (e.g., 914) indicating that the positioning of the portion of the computer system relative to the user's body (e.g., face, eye, or wrist) satisfies the second set of error conditions (e.g., an alert notifying the user that the user input may have reduced accuracy, an alert notifying the user of a potential safety hazard to the user, an alert prompting the user to adjust the positioning of the computer system relative to the user's face, and / or an alert prompting the user to replace and / or change one or more components of the computer system) (e.g., without displaying the first alert), wherein the second alert is different from the first alert and one or more features of the device are accessible when the second alert is displayed. Outputting the first alert and the second alert based on determining that the positioning of the portion of the computer system relative to the user's body satisfies the one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so provides visual feedback to the user regarding the status of the device (e.g., the computer system has determined that the positioning of the computer system relative to the user's body satisfies one or more error conditions). Providing such an alert can also improve user safety by notifying the user of potential safety issues that may arise from one or more error conditions. Providing a first alert that prevents access to one or more features of the computer system until the alert is dismissed also enhances system operability and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends device battery life by enabling the user to use the system more quickly and efficiently.

[0248] In some embodiments, the first alert (e.g., 916) is a viewpoint-locked object, and the second alert (e.g., 914) is an environment-locked object. In some embodiments, the first alert is a viewpoint-locked object that exhibits lazy following behavior (e.g., following the user's viewpoint after a delay and / or after the user moves beyond a threshold amount). Outputting the first and second alerts indicating that the positioning of the portion of the computer system relative to the user's body satisfies one or more error conditions enhances system operability and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the device's battery life by enabling the user to use the system more quickly and efficiently. Furthermore, this provides visual feedback to the user regarding the device's status (e.g., the computer system has determined that the positioning of the computer system relative to the user's body satisfies one or more error conditions).

[0249] In some embodiments, the first alert (e.g., 916) requires one or more user inputs (e.g., one or more touch inputs, one or more gesture inputs, one or more mid-air gesture inputs, and / or one or more hardware inputs) interacting with a user interface (e.g., 916a) to dismiss (e.g., stop displaying) the first alert (e.g., one or more user inputs selecting one or more objects and / or interacting with one or more objects in the displayed user interface), and the second alert (e.g., 914) does not require user input interacting with the user interface to dismiss the second alert (e.g., automatically dismisses and / or automatically stops displaying the second alert when the second set of error conditions ceases to be satisfied). Outputting the first and second alerts indicating that the positioning of the portion of the computer system relative to the user's face satisfies one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. In addition, doing so provides visual feedback to the user about the status of the device (e.g., the device has determined that the positioning of the computer system relative to the user's face satisfies one or more error conditions). Providing such alerts and making certain alerts (e.g., the first alert) more difficult to dismiss can also improve user safety by notifying the user of potential security issues that may be caused by one or more error conditions. Providing a first alert that prevents access to one or more features of the computer system until the alert is dismissed also enhances system operability and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends device battery life by enabling the user to use the system more quickly and efficiently.

[0250] In some embodiments, determining that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body satisfies the second set of error conditions includes determining that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body (e.g., relative to the user's face; and / or determining that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body (e.g., relative to the user's face; and / or relative to one or more features and / or portions of the user's face) is too far to the left, too far to the right, too high, and / or too low. Outputting the second alert based on determining that the computer system is too far to the left, too far to the right, too high, and / or too low relative to the portion of the user's body enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so provides visual feedback to the user regarding the status of the device (e.g., the computer system has determined that the computer system is too far to the left, too far to the right, too high, and / or too low relative to the portion of the user's body).

[0251] In some embodiments, when a second set of error conditions is met (e.g., Figure 9B ), gaze tracking of one or both eyes of the user is less accurate (e.g., less precise) than when the second set of error conditions is not met. In some embodiments, gaze tracking accuracy is affected (e.g., negatively affected) when the second set of error conditions is met. Outputting a second alert based on determining the set of error conditions that negatively impact gaze tracking accuracy makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reduce errors), which additionally reduces power usage and extends battery life of the device by enabling the user to use the system more quickly and efficiently. In addition, doing so provides visual feedback to the user about the status of the device (e.g., the computer system has determined that the computer system meets the set of error criteria that negatively impact gaze tracking accuracy).

[0252] In some embodiments, at a first time, based on a determination that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body satisfies the second set of error conditions, the computer system (e.g., 900) displays, via one or more display generating components, a second alert (e.g., 914). In some embodiments, at a second time after the first time, and while displaying the second alert, based on a determination that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body no longer satisfies the second set of error conditions, the computer system (e.g., 900) ceases display of the second alert (e.g., Figure 9D) (e.g., automatically and / or without user input). In some embodiments, while displaying the second alert, the computer system detects movement of the portion of the computer system relative to the portion of the user's body to a new position; and after detecting movement of the portion of the computer system relative to the portion of the user's body to the new position, based on determining that the new position does not satisfy the second set of error conditions, the computer system ceases display of the second alert. Automatically ceasing display of the second alert when the second set of error conditions is not satisfied allows the operation to be performed with less and / or no user input. Ceasing display of the second alert when the second set of error conditions is no longer satisfied also makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so provides visual feedback to the user about the status of the device (e.g., the computer system has determined that the second set of error conditions is no longer satisfied).

[0253] In some embodiments, upon detecting the positioning of the portion of the computer system relative to the portion of the user's body, the computer system (e.g., 900) displays the image in a first manner (e.g., Figure 9A In response to detecting the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body: determining that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body satisfies a first set of error conditions (e.g., Figure 9E ), a computer system (eg, 900) operates in a second manner (eg, Figure 9E ) displays the first content (e.g., 910 and / or 912) (or, in some embodiments, ceases display of at least a portion of the first content) (e.g., a second manner to indicate that the first content is not currently selected and / or not focused, a second brightness, a second saturation, a second opacity, a second contrast, a second focus, a second clarity, and / or a second manner that visually deemphasizes the first content compared to the first manner (e.g., reduced brightness, reduced saturation, reduced clarity, and / or reduced opacity)) (e.g., displaying the first content in the second manner while displaying the first alert and / or concurrently with displaying the first alert), and based on determining that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body satisfies the second set of error conditions, the computer system (e.g., 900) displays the first content in the first manner (e.g., Figure 9B) maintains display of the first content (e.g., 910 and / or 912) (e.g., while displaying the second alert and / or while concurrently displaying the second alert). Displaying the first content in a second manner while displaying the first alert draws the user's attention to the first alert, which enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently.

[0254] In some embodiments, in a second manner (e.g., Figure 9E ) displaying the first content (e.g., 910 and / or 912) includes displaying the first content in a second manner that visually deemphasizes the first content as compared to the first manner (e.g., reduced brightness, reduced saturation, reduced clarity, and / or reduced opacity as compared to the first manner). In some embodiments, displaying the first content in the second manner includes fading out the first content. Visually de-emphasizing and / or fading out the first content when displaying the first content enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently.

[0255] In some embodiments, while displaying the first content (e.g., 910 and / or 912), the computer system (e.g., 900) receives a first user input (e.g., one or more touch inputs, one or more gesture inputs, one or more mid-air gesture inputs, one or more gaze-based inputs, and / or one or more hardware inputs) via one or more input devices. In response to receiving the first user input: determining to display the first content in a first manner (e.g., Figure 9A and / or Figure 9B ) displays the first content (e.g., when the second set of error conditions is satisfied, when the first set of error conditions is not satisfied, when the second alert is displayed, when the first alert is not displayed, when the first set of error conditions and the second set of error conditions are not satisfied, and / or when the first alert and the second alert are not displayed), the computer system (e.g., 900) modifies display of the first content in response to the first user input; and displays the first content in a second manner (e.g., Figure 9E) displays the first content (e.g., when the first set of error conditions is satisfied and / or when the first alert is displayed), the computer system (e.g., 900) forgoes modifying the display of the first content in response to the first user input. In some embodiments, when the first alert is displayed, the user is prevented and / or prohibited from interacting with the first content until the first alert is dismissed and / or until the first alert ceases to be displayed. Preventing the user from interacting with the first content while the first alert is displayed and / or when the first content is displayed in the second manner enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends battery life of the device by enabling the user to use the system more quickly and efficiently.

[0256] In some embodiments, determining that the positioning of the portion of the computer system (e.g., 900) relative to the portion of the user's body satisfies a first set of error conditions includes determining that the portion of the computer system (e.g., 900) is too close to one or both of the user's eyes (e.g., less than a threshold distance (e.g., less than 8 cm, less than 7 cm, less than 6 cm, less than 5 cm, less than 4 cm, less than 3 cm, less than 2 cm, or less than 1 cm) from one or both of the user's eyes). In some embodiments, the optical seal component (e.g., 1-110 and / or 1-210) extends the computer system away from the user's eyes and / or determines (at least in part) the distance of the portion of the computer system from one or both of the user's eyes. In some embodiments, the light seal (e.g., 1-110 and / or 1-210) is a physical component that fits between the user's face and the computer system, display device, and / or one or more display generating components to block light (e.g., prevent light (e.g., some light and / or all light) (e.g., external light and / or light not output by the computer system, display device, and / or one or more display generating components)) from reaching the user's eyes. In some embodiments, determining that the portion of the computer system is too close to one or both of the user's eyes includes determining that the user should use a light seal (e.g., 1-110 and / or 1-210) having a different physical size (e.g., a greater depth). Outputting a first alert based on determining that the computer system is too close to the user's eyes enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently. In addition, doing so provides visual feedback to the user regarding the status of the device (e.g., the computer system has determined that the computer system is too close to the user's eyes). Providing such alerts may also improve user safety by notifying the user of potential safety issues that may be caused by one or more error conditions.

[0257] In some embodiments, when a first set of error conditions is met (e.g., Figure 9E ), the user is using the computer system in a manner with a reduced safety margin (e.g., degree of safety) compared to when the first set of error conditions is not met. In some embodiments, the first set of error conditions indicates that the device is being used in a manner with a reduced safety margin relative to standard, expected, and / or recommended use. In some embodiments, the first set of error conditions corresponds to eye safety. In some embodiments, the first set of error conditions implements and / or corresponds to industry best practices to ensure that the computer system is being operated safely and that the user is safe. In some embodiments, the first set of error conditions, the second set of error conditions, the first alert, and / or the second alert represent efforts to implement industry best practices to ensure that the computer system is being operated safely and that the user is safe. For example, in some embodiments, the first alert and / or the second alert notify the user when a potential risk to user safety exists and informs the user of steps that can be taken to minimize and / or substantially eliminate the risk to user safety and / or directs the user to resources to ensure that the user is using the device in the safest possible manner. In some embodiments, when the second set of error conditions is met, the user is operating the device within a standard safety margin. In some embodiments, when the second set of error conditions is met, the device operates more safely than when the first set of error conditions is met. Outputting a first alert based on determining a set of error conditions that may negatively impact the user's eye safety improves user safety. This also enhances system operability and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the device's battery life by enabling the user to use the system more quickly and efficiently. Furthermore, this provides visual feedback to the user regarding the status of the device.

[0258] In some embodiments, the first alert (e.g., 916) directs the user to a first set of one or more resources for resolving the error condition (e.g., directs the user to a first set of one or more resources that can assist the user in repairing and / or resolving the error condition). In some embodiments, the one or more resources include one or more URL links. In some embodiments, the one or more resources include contact information for one or more entities (e.g., an email address, a phone number, a physical address, and / or a social media handle). Providing the user with the first set of one or more resources for resolving the error condition enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends the battery life of the device by enabling the user to use the system more quickly and efficiently.

[0259] In some embodiments, one or more resources direct the user to a first store (e.g., a physical store and / or an online store) (e.g., a URL for accessing the online store) to obtain (e.g., purchase and / or exchange) a first accessory of a first set for resolving the error condition (e.g., a first physical accessory and / or a first physical part (e.g., a first light seal (e.g., 1-110 and / or 1-210) (e.g., a physical component that blocks light (e.g., prevents light (e.g., some light and / or all light) (e.g., external light and / or light not output by the computer system, display device and / or one or more display generating components)) from reaching the user's eyes (e.g., a physical component that fits between the user's face and the computer system, display device and / or one or more display generating components))). Providing the user with the one or more resources for resolving the first set of error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user provide appropriate input and reducing errors), which additionally reduces power usage and extends battery life of the device by enabling the user to use the system more quickly and efficiently.

[0260] In some embodiments, a computer system (e.g., 900) detects that a user has stopped using the computer system (e.g., 900) (e.g., detects that the user has removed the computer system from his or her body and / or that one or more parts of the user's body are no longer in a particular position relative to one or more parts of the computer system (e.g., one or both eyes of the user are no longer detected in front of one or more display generating components and / or one or both eyes of the user are no longer detected within an eye-zone of the computer system)). After detecting that the user has stopped using the computer system (e.g., 900), the computer system (e.g., 900) detects that the user has resumed using the computer system (e.g., 900) (e.g., detects that the user has worn the computer system on his or her body and / or detects one or more parts of the user's body in a particular position relative to one or...
