Technical Field

[0004] The present disclosure generally relates to computer systems that provide computer-generated experiences in communication with display generation components and one or more input devices, including but not limited to electronic devices that provide virtual reality and mixed reality experiences via displays. Background Art

[0005] 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 enhance 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

[0006] Some methods and interfaces for gaze tracking registration are cumbersome, inefficient, and limited. For example, systems that provide insufficient feedback for performing actions associated with gaze tracking registration, systems that require a series of inputs to achieve a desired result in an augmented reality environment, and systems in which the manipulation of virtual objects is complex, tedious, and error-prone place a significant cognitive burden on users and detract from the experience of the virtual / augmented reality environment. Furthermore, these methods take longer than necessary, wasting the computer system's energy. This latter consideration is particularly important in battery-powered devices.

[0007] Therefore, there is a need for computer systems with improved methods and interfaces for gaze tracking registration and for providing computer-generated experiences to users, making interactions with computer systems more efficient and intuitive for users. Such methods and interfaces optionally supplement or replace conventional methods for registering a user's gaze and providing extended reality experiences to users. Such methods and interfaces reduce the amount, extent, and / or nature of inputs from users by helping users understand the connection between the inputs provided and the device's responses to those inputs, thereby creating a more efficient human-computer interface.

[0008] The above-mentioned defects and other problems associated with the user interface of the computer system are reduced or eliminated by the disclosed system. 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 notebook computer, a tablet computer, or a handheld device). In some embodiments, the computer system is a personal electronic device (e.g., a wearable electronic device, such as a watch or a head-mounted device). In some embodiments, the computer system has a touch pad. In some embodiments, the computer system has one or more cameras. In some embodiments, the computer system has a touch-sensitive display (also referred to as a "touch screen" or "touch screen 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, which include 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, a memory, and one or more modules, a program or instruction set 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 fingers 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 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.

[0009] There is a need for electronic devices with improved methods and interfaces for gaze tracking registration. Such methods and interfaces can supplement or replace conventional methods for gaze tracking registration. Such methods and interfaces reduce the amount, extent, and / or nature of input from the user and produce a more efficient human-computer interface. Furthermore, such methods and interfaces enable faster and more accurate gaze tracking registration. For battery-powered computing devices, such methods and interfaces conserve power and increase the time interval between battery charges.

[0086] According to some embodiments, the present disclosure relates to a user interface for providing an extended reality (XR) experience to a user.

Figures 7A to 7Y Example techniques for gaze tracking registration according to some embodiments are illustrated. Figure 8 is a flow chart of a method of displaying an enrollment progress user indicator according to various embodiments.

Figure 16 is a flow chart of a method of gaze tracking enrollment according to various embodiments. Figure 17 is a flow chart of a method of providing feedback during gaze tracking enrollment, according to various embodiments. Figures 15A to 15Y The user interface in Figures 16 and 17 in the process. 18A to 18H Example techniques for user registration according to some embodiments are illustrated. Figure 19is a flow chart of a method of user registration according to various embodiments. 18A to 18H The user interface in Figure 19 in the process.

[0088] The processes described below enhance the operability of the device and make the user-device interface more efficient (e.g., by helping the user provide appropriate input and reducing user errors when operating / interacting with the device) through various techniques, including by providing improved visual feedback to the user, reducing the number of inputs required to perform an operation, providing additional control options without cluttering the user interface with additional display controls, performing an operation without further user input when a set of conditions have been met, improving privacy and / or security, providing a richer, more detailed, and / or more realistic user experience while saving storage space, and / or additional techniques. These techniques also reduce power usage and extend the battery life of the device by enabling the user to use the device faster and more efficiently. Saving battery power, and therefore weight, improves the ergonomics of the device. 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.

[0089] In addition, in the method described herein where one or more steps depend on having met one or more conditions, it should be understood that the described method can be repeated in multiple repetitions so that in the process of repetition, all conditions of the steps in the method are met in different repetitions of the method. For example, if the method needs to perform the first step (if the condition is met), and perform the second step (if the condition is not met), then those of ordinary skill will know that the steps stated are repeated until both the condition is met and the condition is not met (in no particular order). Therefore, the method described as having one or more steps depending on having met one or more conditions can be rewritten as a method of repeating until each condition described in the method is met. However, this does not require a system or computer-readable medium to declare that the system or computer-readable medium includes instructions for performing a contingent operation based on the satisfaction of the corresponding one or more conditions, and is therefore able to determine whether a possible situation has been met without explicitly repeating the steps of the method until all conditions of the steps in the method are met. Those of ordinary skill in the art will also understand that, similar to the method with contingent steps, the system or computer-readable storage medium can repeat the steps of the method as needed multiple times to ensure that all contingent steps have been performed.

[0090] 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 household 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).

[0091] 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., by interacting with 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:

[0092] 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.

[0093] 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 properties 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 may 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 properties of virtual objects in the XR environment may 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 implement audio transparency, which selectively introduces ambient sounds from the physical environment with or without computer-generated audio. In some XR environments, people can only sense and / or interact with audio objects.

[0094] Examples of XR include virtual reality and mixed reality.

[0095] 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 a simulation of the person's presence within the computer-generated environment and / or through a simulation of a subset of the person's physical movement within the computer-generated environment.

[0096] Mixed Reality: In contrast to VR environments, which are designed to be based entirely on computer-generated sensory input, a mixed reality (MR) environment refers to a simulated environment that is designed to include 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 may respond to changes in sensory input from the physical environment. Additionally, some electronic systems used to render MR environments may 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 may consider movement so that virtual trees appear stationary relative to the physical ground.

[0097] Examples of mixed reality include augmented reality and augmented virtuality.

[0098] Augmented Reality: An augmented reality (AR) environment refers to a simulated environment in which one or more virtual objects are superimposed on a physical environment or a representation of a physical environment. For example, an electronic system for presenting an AR environment may have a transparent or translucent display through which a person can directly view the physical environment. The system may be configured to present virtual objects on a transparent or translucent display so that a person using the system perceives the virtual objects superimposed on the physical environment. Alternatively, the system may have an opaque display and one or more imaging sensors that capture images or videos of the physical environment, which are representations of the physical environment. The system combines the images or videos with the virtual objects and presents the combination on an opaque display. A person uses the system to indirectly view the physical environment via the images or videos of the physical environment and perceives the virtual objects superimposed on the physical environment. As used herein, a video of the physical environment displayed on an opaque display is referred to as "transparent video," meaning that the system captures images of the physical environment using one or more image sensors 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 the representation of the physical environment is transformed by computer-generated sensory information. For example, when providing a 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 non-realistic version of the original captured image. For another example, the representation of the physical environment may be transformed by graphically eliminating a portion thereof or blurring a portion thereof.

[0099] 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, a virtual object may adopt the shape or color of a physical object imaged by one or more imaging sensors. In another example, a virtual object may adopt a shadow that matches the sun's position in the physical environment.

[0100] 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), and the virtual viewport has a viewport boundary that defines the range 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 boundary 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 properties 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 boundary 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 properties 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 boundary typically move with the movement of 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 smart phone). The user's viewpoint determines what is visible in the viewport. The viewpoint typically specifies a position and orientation relative to the three-dimensional environment, and as the viewpoint moves, the view of the three-dimensional environment will also shift 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 view of the three-dimensional environment that is perceptually accurate and provides an immersive experience when the user is using the head-mounted device. For handheld or fixed devices, the viewpoint shifts as the handheld or fixed device moves and / or as the user's positioning relative to the handheld or fixed device changes (e.g., the user moves toward the device, away from the device, 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 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 position and pose of the virtual objects are updated based on movement of the user's viewpoint)).For display generation components with optical transmittance, portions of the physical environment that are visible via one or more display generation components (e.g., optically visible through one or more partially or fully transparent portions of the display generation components) are based on the user's field of view through the partially or fully transparent portions of the display generation components (e.g., moves with movement of the user's head for a head-mounted device, or moves with movement of the user's hand for a handheld device such as a tablet or smart phone) 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 generation components (and the appearance of one or more virtual objects is updated based on the user's viewpoint).

[0101] In some embodiments, the representation of the physical environment (e.g., displayed via virtual see-through or optical see-through) may be partially or completely obscured by the virtual environment. In some embodiments, the amount of virtual environment displayed (e.g., the amount of 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, thereby 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, 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 generated by a computer system corresponding to an application), 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), 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 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 concurrently 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 that is 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 display). For example, a corresponding virtual environment with a high immersion level is displayed without concurrently displaying background content (e.g., in full screen or fully immersive mode). As another example, a virtual environment displayed at a medium immersion level is displayed concurrently 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 more than one or more second background objects (e.g., dimmed, blurred, and / or displayed with increased transparency), and one or more third background objects cease to be displayed. In some embodiments, zero immersion 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.

[0102] 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 display generation component of the computer system. 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 when 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."

[0103] 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 shifts, 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) such 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 position and / or orientation 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, animal, 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 of the user) 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.

[0104] In some embodiments, an environment-locked or viewpoint-locked virtual object exhibits an inertial following behavior that 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 follows. In some embodiments, when exhibiting inertial following behavior, the computer system intentionally delays the movement of the virtual object when 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) is detected. 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 inertial following behavior, the device ignores small amounts of movement of the reference point (e.g., ignoring movements of the reference point below a threshold movement amount, such as moving 0 degrees to 5 degrees or moving 0 cm 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 that is 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 that is 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).

[0105] 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 known 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 concurrently presented to the viewer's second eye. The first image and the second image 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 concurrently displays the second image via a second display different from the first display positioned for viewing by the viewer's second eye. In some embodiments, when viewed together, the first image and the second image 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 a first perspective is presented to the viewer's first eye, and a second video representing a second perspective different from the first perspective is concurrently 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 the headphones is produced by manipulating the sounds in the 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 may reproduce a spatial audio signal that simulates a soundscape surrounding a listener (also referred to as a user). Effective spatial sound reproduction may 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.

[0106] 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 the sound source. By taking into account the impact of the listener's pinna, the listener's head, and the listener's torso on the sound that enters the listener's ear canal, a spatial audio sound experience may be achieved. The geometry of the user's ear is optionally determined using a three-dimensional scanning device that produces a three-dimensional model of at least a portion of the visible part of the user's ear. This geometry is optionally used to generate filters for producing a spatial audio experience. In some embodiments, spatial audio is audio that has been filtered so that a listener of the audio 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).

[0107] 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 so that the sound experienced by the listener through headphones (e.g., in-ear headphones, on-ear headphones, and / or circumaural headphones) is 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) because the listener's ears may have different geometries.

[0108] 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.

[0109] Hardware: There are many different types of electronic systems that 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. A head-mounted system may have a transparent or translucent display instead of an opaque display. A transparent or translucent display may have a medium through which light representing an image is directed to a person's eyes. The display may utilize digital light projection, OLED, LED, uLED, liquid crystal on silicon, a laser scanning light source, or any combination of these technologies. The medium may be an optical waveguide, a hologram medium, an optical combiner, an optical reflector, or any combination thereof. In one embodiment, the transparent or translucent display may be configured to selectively become opaque. Projection-based systems may employ retinal projection technology that projects graphic images onto a person's retina. The projection system may 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., physical environment). For example, controller 110 is a local server located within scene 105. As 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., HMD, display, projector, 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.

[0110] 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.

[0111] According to some embodiments, display generation component 120 provides an XR experience to the user when the user is virtually and / or physically present within scene 105.

[0112] In some embodiments, the display generation component is worn on a part of the user's body (e.g., on his / her head, on his / her hand, 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 smart phone or tablet device) configured to present XR content, and the user holds a 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 in 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 that are triggered based on interactions that occur in the space in front of a handheld device or a tripod-mounted device can similarly be implemented with 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 that are 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 with 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)).

[0113] Although Figure 1A Relevant features of the operating environment 100 are shown in FIG, but persons of ordinary skill 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.

[0114] 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., a first display assembly 1-120a and a second display assembly 1-120b and / or a first optical module 11.1.1-104a and a second optical module 11.1.1-104b) for displaying representations of virtual elements and / or the physical environment to a user of the computer system, the representations of these virtual elements and / or the physical environment being optionally 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, which are optionally removably attached to one or more of the optical modules to enable the user interface to be more easily viewed by a user who would otherwise use glasses or contact lenses to correct their vision.

[0147] 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 the form of a pattern of light dots that reflect off an object and return to the depth sensors described above, including the depth sensors 6-108, 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.

[0148] 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.

[0149] 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 beneath the HMD device 6-100, including the user's jaw, cheeks, mouth, and chin. Used for hand and body tracking, headset tracking, and facial avatar

[0150] 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. In at least one example, the side camera 6-118 may be used for hand and body tracking, headset tracking, and facial avatar detection and reconstruction.

[0151] 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.

[0152] 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.

[0153] In at least one example, multiple 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) can 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, the above and Figure 1I The downward camera 6-114, the jaw camera 6-116, and the side camera 6-118 shown can be wide-angle cameras that can operate in the visible and infrared spectrum. 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.

Figures 1J 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 1I Examples of equipment, features, assemblies, and parts are shown.

[0155] Figure 1J A bottom perspective view of an example of an HMD 6-200 including a cover or shroud 6-204 secured to a frame 6-230 is illustrated. In at least one example, the sensors 6-202 of the sensor system 6-203 may be disposed around the perimeter of the HMD 6-200 such that the sensors 6-203 are disposed outwardly around the perimeter of the display area or area 6-232 so as not to obstruct viewing 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.

[0156] 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 6-204 of the shield 6-207 may define one or more transparent areas 6-209 through which the sensors 6-203 of the sensor system 6-202 may send and receive signals. In the illustrated example, the sensors 6-203 of the sensor system 6-202 that send and receive signals through the shield 6-204, or more specifically, through the transparent areas 6-209 defined by the opaque portion 6-207 of the shield 6-204, may include sensors 6-203 of the sensor system 6-202 that send and receive signals through the shield 6-204, or more specifically, through the transparent areas 6-209 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 depth sensors 6-108 and 6-110, depth projector 6-112, first and second scene cameras 6-106, first and second downward cameras 6-114, first and second side cameras 6-118, and 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.

[0157] Figure 1J Any of the features, components and / or parts shown (including their arrangement and configuration) may be included alone or in any combination in the Figure 1I and Figures 1K to 1L Any of the other examples of devices, features, components, and parts shown and described herein. 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.

[0158] Figure 1K Illustrated is 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. Figure 1K The example shown does not include a front cover or shield in order to illustrate the brackets 6-336, 6-338. For example, Figure 1J The illustrated shield 6-204 includes an opaque portion 6-207 that would visually cover / block the view of anything outside (e.g., radially / peripherally outside) the display / display area 6-334, including the sensor 6-303 and bracket 6-338.

[0159] 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 brackets 6-226, the housing 6-330, and / or the shield.

[0160] Figure 1K Any of the features, components and / or parts shown (including their arrangement and configuration) may be included alone or in any combination in the Figures 1I to 1J and Figure 1L Any of the other examples of devices, features, components, and parts shown and described herein. Figures 1I to 1J and Figure 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 1K Examples of equipment, features, assemblies, and parts are shown.

[0161] Figure 1L A bottom view of an example of an HMD 6-400 including a front display / cover assembly 6-404 and a sensor system 6-402 is illustrated. The sensor system 6-402 may be similar to that described above and elsewhere herein (including with reference to FIG. Figures 1I to 1K ) as described above. 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 send and receive signals.

[0163] Figure 1M Illustrated is a rear perspective view of an interpupillary distance (IPD) adjustment system 11.1.1-102 comprising a first optical module 11.1.1-104a and a second optical module 11.1.1-104b slidably engaged / coupled to respective guide rods 11.1.1-108a-b and motors 11.1.1-110a-b of a left adjustment subsystem 11.1.1-106a and a right adjustment subsystem 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-b. In at least one example, the button 11.1.1-114 may be in electrical communication with the first and second motors 11.1.1-110a, 11.1.1-110b via a processor or other circuit component to activate the first and second motors 11.1.1-110a, 11.1.1-110b and respectively change positioning of the first and second optical modules 11.1.1-104a, 11.1.1-104b relative to each other.

[0164] In at least one example, the first and second optical modules 11.1.1-104a-b 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., depress and / or rotate) a button 11.1.1-114 to activate positioning adjustment of the optical modules 11.1.1-104a-b to match the interpupillary distance of the user's eyes. The optical modules 11.1.1-104a-b may also include one or more cameras or other sensors / sensor systems for imaging and measuring the user's IPD so that the optical modules 11.1.1-104a-b can be adjusted to match the IPD.

[0165] In one example, a user can manipulate button 11.1.1-114 to cause automatic positioning adjustment of the first and second optical modules 11.1.1-104a-b. In one example, a user can manipulate button 11.1.1-114 to cause manual adjustment, causing the optical modules 11.1.1-104a-b to move further or closer (e.g., when the user rotates button 11.1.1-114 one way or another) 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-b via motors 11.1.1-110a-b is provided by a power source. In one example, adjustment and movement of the optical modules 11.1.1-104a-b via manipulation button 11.1.1-114 is mechanically actuated via movement button 11.1.1-114.

[0166] Figure 1M Any of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included, alone or in any combination, in any of the other examples of devices, features, components, and parts shown in any of the other figures shown and described herein. Similarly, any of the features, components, and / or parts shown and described in any of the other figures shown and described herein (including arrangements and configurations thereof) may be included, alone or in any combination, in any of the other examples of devices, features, components, and parts shown in any of the other figures shown and described herein. Figure 1M Examples of equipment, features, assemblies, and parts are shown.

[0167] Figure 1N Illustrated is a front perspective view of a portion of an HMD 11.1.2-100 including an outer structural frame 11.1.2-102 and an inner or intermediate structural frame 11.1.2-104 defining a first aperture 11.1.2-106a and a second aperture 11.1.2-106b. Figure 1N 2-106a-b 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 aperture 11.1.2-106a and the second aperture 11.1.2-106b.

[0168] 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 a first cantilevered extension arm and a second cantilevered extension arm 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.

[0169] like Figure 1N As shown, the outer frame 11.1.2-102 can define a curved geometry on its underside 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-b so 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 manner, 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 adapts to the nose in that 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.

[0170] 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.

[0171] 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 accurate 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 altered 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 frame and / or outer frame 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 positioning of the sensors 11.1.2-110a-f coupled / mounted to the mounting bracket 11.1.2-108.

[0172] Figure 1NAny of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included, alone or in any combination, in any of the other examples of devices, features, components, and apparatus described herein. 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 of the other examples of devices, features, components, and apparatus described herein. Figure 1N Examples of equipment, features, assemblies, and parts are shown.

[0173] Figure 1O An example of an optical module 11.3.2-100 for an electronic device (such as an HMD, including the HMD devices described herein) is illustrated. 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.

[0174] 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0179] Figure 1P A cross-sectional view of an example of an optical module 11.3.2-200 is illustrated, 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 guide rods to secure the optical module 11.3.2-200 in place within the HMD.

[0180] 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 positioned 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.

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).

[0196] 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.

[0197] 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.

[0198] 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.).

[0202] 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 transmission unit 348 may be located in a separate computing device.

[0203] also, Figure 3 It serves more as a functional description of various features that may be present in a particular embodiment, rather than as a structural schematic 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.

[0204] 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 ) by the hand tracking unit 244( Figure 2 ) controls to track the position / location of one or more parts of a user's hand, and / or one or more parts of a user's hand relative to Figure 1A The hand tracking device 140 is configured to track movement of the scene 105 relative to the user's physical environment, 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 defined about the user's hands. 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).

[0205] In some embodiments, the 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. The image sensor 404 captures images of the hand at a sufficient resolution to enable the fingers and their respective positioning to be distinguished. The 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 have zoom capabilities or specialized sensors with increased magnification to capture images of the hand at a desired resolution. In some embodiments, the image sensor 404 also captures 2D color video images of the hand 406 and other elements of the scene. In some embodiments, the image sensor 404 is used in conjunction with other image sensors to capture the physical environment of the scene 105, or serves as an image sensor for capturing the physical environment of the 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 the image sensor 404, or a portion thereof, is used to define an interaction space in which hand movements captured by the image sensor are treated as input to the controller 110.

[0206] 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 via an application program interface (API) to an application running on the controller, 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.

[0207] In some embodiments, the image sensor 404 projects a speckled pattern onto a scene containing the hand 406 and captures an image of the projected pattern. In some embodiments, the 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 method gives the depth coordinates of a point in the scene relative to a predetermined reference plane at a specific distance from the image sensor 404. In the present disclosure, it is assumed that the image sensor 404 defines an orthogonal set of x-axis, y-axis, and z-axis such that the depth coordinates of a point in the scene correspond to the z component measured by the image sensor. Alternatively, the image sensor 404 (e.g., a hand tracking device) may use other 3D mapping methods, such as stereo imaging or time-of-flight measurement, based on a single or multiple cameras or other types of sensors.

[0208] 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 his 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 in 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.

[0209] 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 function described herein can be interleaved with the motion tracking function so that the image patch-based pose estimation is performed only once every two (or more) frames, and tracking is used to find changes in pose that occur over the remaining frames. The pose, motion, and gesture information is provided to the application running on the controller 110 via the above-mentioned 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.

[0210] 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 more arms, one or more hands, one or more fingers, and / or one or more legs) through 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 in which the hand moves a predetermined amount and / or speed in a predetermined posture, or a shake gesture including a predetermined speed or amount of rotation of a part of the user's body)).

[0211] In some embodiments, according to some embodiments, the input gestures used in the various examples and embodiments described herein include air gestures for interacting with an XR environment (e.g., a virtual or mixed reality environment) performed by movement of a user's fingers relative to other fingers (or parts of the user's hands). In some embodiments, an air gesture is a gesture detected without the user touching an input element that is part of the device (or independent 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 in which the hand moves a predetermined amount and / or speed in a predetermined posture, or a shake gesture in which a part of the user's body is rotated at a predetermined speed or amount)).

[0212] 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 the 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 with (e.g., concurrently 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.

[0213] In some embodiments, an input gesture directed to a user interface object is performed directly or indirectly with reference to the user interface object. For example, user input is performed directly on the user interface object based on performing input with the user's hand at a location corresponding to the location of the user interface object in the three-dimensional environment (e.g., as determined based on the user's current viewpoint). In some embodiments, upon detecting user attention (e.g., gaze) to the user interface object, an input gesture is performed indirectly on the user interface object based on the user's hand being located not at the location corresponding to the location of the user interface object in the three-dimensional environment while the user performs the input gesture. For example, for a direct input gesture, the user can direct the user's 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 the outer edge of the option or the center portion of the option). For an indirect input gesture, the user can direct the user's 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 that does not correspond to the displayed location of the user interface object).

[0214] In some embodiments, according to some embodiments, input gestures (e.g., air gestures) used in various examples and embodiments described herein include pinch input and tap input for interacting with a virtual or mixed reality environment. For example, the pinch input and tap input described below are performed as air gestures.

[0215] 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 in contact with each other, optionally followed by immediate (e.g., within 0 to 1 second) breaking contact with each other. 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 with each other immediately (e.g., within a predefined time period). 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., interrupts 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.

[0216] In some embodiments, a pinch and drag gesture that is an air gesture (e.g., an air drag gesture or an air swipe gesture) includes a pinch gesture (e.g., a pinch gesture or a long pinch gesture) performed in conjunction with a drag input that changes (e.g., follows) 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 the second position in the air using the 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 that is 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) occurs.

[0217] 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., an 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).

[0218] 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).

[0219] 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 a 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 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 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 to prepare for a pinch or grab gesture, or a pre-tap 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 (e.g., gaze) input.

[0220] In scenarios where input is described with reference to in-air gestures, it should be understood that similar gestures may be detected using a hardware input device attached to or held by one or more hands of a user, where the positioning of the hardware input device in space may 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 in place of the positioning and / or movement of the one or more hands in the corresponding in-air gesture. In scenarios where input is described with reference to in-air poses, it should be understood that similar poses may be detected using a hardware input device attached to or held by one or more hands of a user. User input may be detected using controls contained in hardware input devices, 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 using the controls contained in the hardware input device is used in place of hand and / or finger gestures such as an air tap or air pinch in a corresponding air gesture. For example, a selection input described as being performed using an air tap or air pinch input may 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 an air pinch and drag (e.g., an air drag gesture or an air swipe gesture) 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 followed by movement of a hardware input device (e.g., along with the hand with which the hardware input device is associated) through space. Similarly, two-handed input involving movement of hands relative to each other may be performed using one air gesture and one hardware input device in the hand that is not performing the air gesture, two hardware input devices held in different hands, or two air gestures performed by different hands using various combinations of air gestures and / or inputs detected by one or more of the aforementioned hardware input devices.

[0221] 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 in addition, 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 device 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 integrated 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.

[0222] Figure 4 Also included is a schematic diagram of a depth map 410 captured by the image sensor 404 according to some embodiments. As described above, the depth map includes a matrix of pixels with corresponding depth values. Pixels 412 corresponding to the hand 406 have been segmented from the background and wrist in the 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), where gray shades become darker with increasing depth. The controller 110 processes these depth values in order to identify and segment components of the image (i.e., groups 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.

[0223] Figure 4 Also schematically illustrated is a hand skeleton 414 that the controller 110 ultimately extracts from the depth map 410 of the hand 406 according to 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 a gesture performed by the hand or the current state of the hand according to some embodiments.

[0224] 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 part 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.

[0225] 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 a left image and a right image 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 a left optical lens and a right optical lens (referred to herein as eye lenses) located 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 have 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. The virtual objects may, for example, be projected onto a physical surface or projected as a hologram, so that an individual using the system observes 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.

[0226] like Figure 5As shown in , in some embodiments, the 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 the user's eyes. The eye tracking camera can be pointed at the user's eyes to receive IR or NIR light that the light source reflects directly from the eyes, or alternatively can be pointed at "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 camera and illumination source.

[0227] 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. According to some embodiments, the user-specific calibration process may include an estimation of eye parameters of a specific user, such as pupil position, fovea position, optical axis, visual axis, eye spacing, etc. According to 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 current visual axis and the user's gaze point relative to the display.

[0228] 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 that includes 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 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) 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 ).

[0229] 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 for 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.

[0230] 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.

[0231] 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., illumination source 530 (e.g., IR or NIR LED)). 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 illumination sources 530 (e.g., LEDs) are arranged around each lens 520. However, more or fewer illumination sources 530 can be used, and other arrangements and positions of illumination sources 530 can be used.

[0232] In some embodiments, the display 510 emits light in the visible range and does not emit light in the IR or NIR range, and therefore does not introduce noise into the gaze tracking system. It should be noted 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.

[0233] like Figure 5 Embodiments of the illustrated 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 augmented virtual experience.

[0234] Figure 6 A flash-assisted gaze tracking pipeline according to some embodiments is illustrated. In some embodiments, the gaze tracking pipeline is composed of 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." When in the tracking state, the flash-assisted gaze tracking system uses previous 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.

[0235] 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.

[0236] 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.

[0237] 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 can be trusted. 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 not likely to be trusted, 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 trustworthy, 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.

[0238] Figure 6 This is intended to be used as an example of an eye tracking technology that may be used for a particular implementation. As one of ordinary skill in the art will appreciate, according to various embodiments, other eye tracking technologies currently existing or developed in the future may be used in place of or in combination with the flash-assisted eye tracking technology described herein in the computer system 101 for providing an XR experience to a user.

[0239] 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 superimposed on a representation of the real-world environment 602.

[0240] 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 camera and display of a computer system or passively displayed via a transparent or translucent 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 is optionally capable of selectively displaying portions and / or objects of the physical environment so 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 is optionally capable of displaying virtual objects in the three-dimensional environment so that it appears as if the virtual objects exist in the real world (e.g., a 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 so that the vase appears as if a real vase is 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 a location at or near a user's hand or at a location 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 the real object at that particular location).

[0241] 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.

[0242] In a three-dimensional environment (e.g., a real environment, a virtual environment, or an environment comprising a mixture of real objects 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 the user's position or viewpoint, in which case the depth dimension varies based on the position and angle of the user's position and / or the user's viewpoint. In some embodiments where depth is defined relative to the user's position relative to the 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 an object 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.

[0243] In some embodiments, the 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 optionally capture one or more 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 the three-dimensional environment described above), or 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 field of view of the user's eyes, via the ability to see the physical environment through the user interface. Thus, in some embodiments, the user's hands are displayed at corresponding locations in the three-dimensional environment and are viewed as if they were objects in the three-dimensional environment, and these objects can interact with virtual objects in the three-dimensional environment as if these virtual objects 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.

[0244] 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 and pinching / holding the user interface of an application, and performing 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, the user's hand(s) are positioned at a specific location in the physical world, and the computer system optionally captures the hand(s) and displays the hand(s) at a specific corresponding location in the three-dimensional environment (e.g., the location at which the hand(s) would be displayed in the three-dimensional environment if the hand(s) were virtual hands rather than physical hands). The location of the hand(s) in the three-dimensional environment is optionally compared to the location of the virtual object(s) of interest in the three-dimensional environment to determine the distance between the user's hand(s) and the virtual object(s). In some embodiments, the computer system optionally determines the distance between the physical object(s) and the virtual object(s) 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(s) and the virtual object(s), the computer system optionally determines the corresponding location of the virtual object(s) in the physical world (e.g., the location at which the virtual object(s) would be located in the physical world if the virtual object(s) were physical objects rather than virtual objects), and then determines the distance between the corresponding physical location and the user's hand(s). 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.

[0245] 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.

[0246] 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 is used as a proxy for the position of the user. 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) that, if the user were standing at that position, facing the corresponding portion of the physical environment visible via the display generation component, would be visible to the user from that position in the physical environment in the same position, orientation, and / or size (e.g., in absolute terms and / or relative to each other) as the objects displayed in the three-dimensional environment by the display generation component of the computer system or visible in the three-dimensional environment via the display generation component. 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 located 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.

[0247] 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.

[0248] User interface and associated processes

[0249] Attention is now directed 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 display generation components and one or more input devices.

[0250] Figures 7A to 7Y Example techniques for gaze tracking registration according to some embodiments are illustrated. Figure 8 is a flow chart of a method of displaying an enrollment progress user indicator according to various embodiments.

[0251] Figure 9 is a flow chart of a method of animating movement of a user interface element according to various embodiments.

[0252] Figure 10 is a flow chart of a method of changing the appearance of a user interface element according to various embodiments. Figure 11 is a flowchart of a method of moving a user interface element over time according to various embodiments. Figures 7A to 7Y The user interface in the example is used to illustrate the following process, including Figures 8 to 11 in the process.

[0253] Figure 7A A computer system 700 is illustrated having a display 702. Figure 7AAs illustrated, before beginning the process for registering the user's gaze, the computer system 700 displays an indication 704 of a company, such as the manufacturer of the computer system 700 and / or the manufacturer of the software (e.g., applications and / or operating system) for the computer system 700. In some embodiments, the computer system 700 can be configured to present virtual objects on one or more transparent or semi-transparent displays (e.g., 702) so that a person using the system perceives the virtual objects superimposed on a physical environment. In some embodiments, the computer system 700 is configured to use pass-through video, which means that one or more cameras or image sensors capture images of the physical environment and use those images when presenting the AR environment on an opaque display.

[0254] although Figures 7A to 7Y The techniques using the computer system 700 as a tablet are illustrated, but these techniques are optionally also applicable to the use of a head-mounted device. In some embodiments where the computer system 700 is a head-mounted device, the computer system 700 optionally includes two displays (one display for each eye of the user of the computer system 700), wherein each display displays corresponding various content to enable the user to perceive various depths of the various content. For head-mounted devices, multiple displays are optionally used to present slightly different images to different eyes of the user to create a stereoscopic depth effect. Additionally, for head-mounted devices, different sensors or sensor groups may be used to track different eyes of the user to more accurately determine the position corresponding to the gaze of the eyes. Accurate gaze tracking is particularly important for head-mounted devices, where gaze is often used to indicate where attention is being directed in a three-dimensional environment, and optionally used to determine what element of the three-dimensional environment the input is directed to (e.g., via hardware input, air gestures, and / or gaze input). For devices that use gaze tracking (such as tablets, phones, desktop computers, and head-mounted devices), improved gaze registration results in improved gaze tracking by the device, which makes input more precise and reduces the need to repeatedly attempt to perform operations, thereby reducing power usage and increasing battery life (for battery-powered devices).

[0255] In some embodiments, the company's indication 704 is displayed as an initial screen after (and / or in response to) startup of the computer system 700. After a period of time (e.g., 1 second, 2 seconds, or 5 seconds), the computer system 700 automatically transitions to displaying the three-dimensional environment 712, as shown in FIG. Figure 7B1 exemplified.

[0256] exist Figure 7B1, three-dimensional environment 712 is part of an extended reality environment. In some embodiments, three-dimensional environment 712 is a virtual reality environment, and sofa 712A is a virtual object displayed as part of the extended reality environment. In some embodiments, three-dimensional environment 712 is an augmented reality environment, and sofa 712A is a representation of a physical object in a physical environment. In some embodiments in which three-dimensional environment 712 is part of an augmented reality environment, sofa 712A (and other physical objects from the physical environment) are presented to the user of computer system 700 using pass-through video (e.g., sofa 712A is presented by capturing video of the sofa via one or more cameras and displaying the video on display 702 (e.g., in real time)). In some embodiments in which three-dimensional environment 712 is part of an augmented reality environment, sofa 712A (and other physical objects from the physical environment) are presented to the user of computer system 700 using one or more transparent or semi-transparent displays (e.g., sofa 712A is presented to the user by enabling the user to see sofa 712A through display 702). The three-dimensional environment 712 also includes a display of a target 714, which is a virtual object displayed as part of the three-dimensional environment 712. In some embodiments, the target 714 is a three-dimensional virtual object (e.g., a sphere and / or cylinder). The target 714 optionally includes a light source that simulates light emanating from the target 714 into objects (e.g., virtual objects and / or physical objects) in the three-dimensional environment 712.

[0257] When computer system 700 displays target 714, computer system 700 detects the user's gaze 750A of computer system 700. Where the gaze of the user is directed is indicated by the gaze indication (such as gaze 750A), and is illustrated for better understanding of this technology. In some embodiments, the indication of the position of the user's gaze is not displayed as a part of the user interface of computer system 700. In some embodiments, the indication of the position of the user's gaze is displayed. In response to detecting gaze 750A and according to determining that gaze 750A has pointed to target 714 and reached a threshold time amount, computer system 700 initiates the animation of target 714, as further described below. In some embodiments, the threshold time amount is zero, and any gaze at target 714 places initiates this animation. In some embodiments, the threshold time amount is non-zero, and the gaze pointing to target 714 must continue the duration of the threshold time amount just to initiate animation.

[0258] In some embodiments, Figures 7A to 7Y The technology and user interface described are provided by Figures 1A to 1P One or more of the devices described above may be provided. For example, Figure 7B2 714 (e.g., Figure 7B1In 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.

[0259] exist Figure 7B2 , the three-dimensional environment 712 is part of an extended reality environment. In some embodiments, the three-dimensional environment 712 is a virtual reality environment, and the sofa 712A is a virtual object displayed as part of the extended reality environment. In some embodiments, the three-dimensional environment 712 is an augmented reality environment, and the sofa 712A is a representation of a physical object in the physical environment. In some embodiments in which the three-dimensional environment 712 is part of an augmented reality environment, the sofa 712A (and other physical objects from the physical environment) are presented to the user of the HMD X700 using pass-through video (e.g., the sofa 712A is presented by capturing video of the sofa via one or more cameras and displaying the video on the display X702 (e.g., in real time)). In some embodiments in which the three-dimensional environment 712 is part of an augmented reality environment, the sofa 712A (and other physical objects from the physical environment) are presented to the user of the HMD X700 using one or more transparent or semi-transparent displays (e.g., the sofa 712A is presented to the user by enabling the user to see the sofa 712A through the display X702). The three-dimensional environment 712 also includes a display of a target 714, which is a virtual object displayed as part of the three-dimensional environment 712. In some embodiments, the target 714 is a three-dimensional virtual object (e.g., a sphere and / or cylinder). The target 714 optionally includes a light source that simulates light emanating from the target 714 into objects (e.g., virtual objects and / or physical objects) in the three-dimensional environment 712.

[0260] While HMD X700 displays target 714, HMD X700 detects gaze X750A of the user of HMD X700. A gaze indication, such as gaze X750A, indicates where the user's gaze is directed and is illustrated for a better understanding of the technology. In some embodiments, the indication of the location of the user's gaze is not displayed as part of the user interface of HMD X700. In some embodiments, the indication of the location of the user's gaze is displayed. In response to detecting gaze X750A and based on determining that gaze X750A has been directed toward target 714 for a threshold amount of time, HMD X700 initiates animation of target 714, as further described below. In some embodiments, the threshold amount of time is zero, and any gaze at target 714 initiates the animation. In some embodiments, the threshold amount of time is non-zero, and the gaze directed toward target 714 must continue for the duration of the threshold amount of time to initiate the animation.

[0261] 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. Any of the features, components and / or parts of 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 lenticular lens array 3-110, the display area or zone 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), which is optionally generated based on detected events and / or user input detected by HMD X700.

[0262] exist Figure 7CAt , computer system 700 has initiated animation of target 714, and therefore, target 714 is scaled down, as shown in FIG. Figure 7C After shrinking, the target 714 is replaced with (e.g., expanded into and / or transformed into) a registration element to begin the gaze registration process (e.g., to calibrate the detection of the user's gaze and / or train the user how to use their gaze to interact with elements of the three-dimensional environment). In some embodiments, the target 714 shrinks and then expands into the registration element. In some embodiments, the registration element indicates the amount of progress made in registering the user's gaze, and optionally, the visual appearance of the registration element changes based on the change in the user's gaze detected by the computer system 700.

[0263] In some embodiments, in addition to (or as an alternative to) detecting the location of the user's gaze, the computer system 700 also detects pupil dilation information about the user (e.g., the amount of dilation or contraction and / or pupil size). For example, the computer system 700 may gradually (or suddenly) increase and / or decrease the overall brightness of the content presented to the user via the display 702 to cause the user's pupil to dilate and / or contract. For example, the computer system 700 may darken and / or brighten the appearance of the physical environment via the display 702 before, during, and / or during the gaze registration process to cause the pupil to dilate and / or contract and detect / collect corresponding pupil dilation information. For example, when the environment presented to the user is dim, and also when the brightness (e.g., overall brightness) of the content presented to the user changes (brightens and / or darkens) throughout the gaze registration process, the computer system 700 optionally collects Figure 7A Pupil dilation information at .

[0264] In some embodiments, target 714 is viewpoint locked. In some embodiments, target 714 is context locked. As discussed, target 714 is replaced with a registration element (e.g., the registration element is displayed at the same location as target 714). In some embodiments, the registration element is context locked. In some embodiments, as Figure 7D As illustrated, target 714 is replaced with a registration element 720 comprising a plurality of portions 720A-720H. In some embodiments, as Figure 7H As illustrated, target 714 is replaced with a registration element 730 comprising a plurality of parts, including parts 730A-730E. In some embodiments, as Figure 7L As illustrated, target 714 is replaced with a registration element 740 comprising a plurality of parts, including parts 740A-740E. In some embodiments, as Figure 7Q As illustrated, target 714 is replaced with a registration element 760 comprising a plurality of parts, including parts 760A-760E. In some embodiments, as Figure 7VAs illustrated, target 714 is replaced with registration element 770 .

The registration element 720 includes a central portion 720I and a plurality of portions 720A-720H at least partially surrounding the central portion 720I. When initially displayed, the portions 720A-720H have the same appearance (e.g., the same length, the same color, the same size, and / or the same shape).

[0266] exist Figure 7E At this point, when the computer system 700 begins to detect that the user is gazing around the three-dimensional environment 712, the computer system 700 changes the appearance of the corresponding portions 720A-720H based on the location of the user's gaze. Figure 7E Two alternative gaze paths 722 (corresponding to gaze 750B) and 724 (corresponding to gaze 750C) within the three-dimensional environment 712 are illustrated. Both gaze paths 722 and 724 are valid paths (having different start / end locations) and enable the computer system 700 to detect gaze information during the gaze registration process. The gaze paths indicate the paths taken by the user's gaze and are illustrated for a better understanding of the technology. In some embodiments, the gaze paths are not displayed as part of the user interface of the computer system 700.

[0267] In some embodiments, the corresponding portions 720A-720H grow in length to indicate that the computer system 700 has detected that the user is gazing at a location corresponding to the corresponding portion. Figure 7E At 750B, gaze 750B begins at the lower left of registration element 720. Figure 7E At the location of gaze 750B at the computer system 700, the appearance of portion 720A is changed to indicate that the user's gaze has been detected. The gaze corresponds to the location of portion 720A. Figure 7F At , as the computer system 700 continues to detect that gaze 750B moves along gaze path 722, the computer system 700 sequentially changes the appearance of portions 720B-720D to indicate that the user's gaze has been detected at locations corresponding to those portions. Figure 7G At , the computer system 700 has detected that the gaze 750B has moved along the gaze path 722 completely (or nearly completely) around the central portion 720I of the registration element 720, and therefore, the appearance of all portions 720A-720H has changed to be longer in length (compared to the central portion 720I of the registration element 720).

Because the computer system 700 has detected that the user is gazing at positions corresponding to all portions 720A-720H, that portion of the gaze registration is complete, and the computer system 700 proceeds to replace the registration element 720 with (e.g., shrinking it to and / or transforming it into) the target 714, as shown. Figure 7Y exemplified.

[0268] In some embodiments, the computer system 700 Figures 7A to 7G In some embodiments, the computer system 700 collects gaze information and / or pupil dilation information throughout the described process (including in the case of varying brightness) in order to register the user's gaze so that the user can more accurately aim at elements (physical and / or virtual) in a three-dimensional environment, such as the three-dimensional environment 712.

Both gaze paths 732 and 734 are valid paths (having different start / end locations) and enable the computer system 700 to detect gaze information during the gaze registration process. The gaze paths indicate the paths taken by the user's gaze and are illustrated for a better understanding of the technology. In some embodiments, the gaze paths are not displayed as part of the user interface of the computer system 700.

Figure 7H At 750D, gaze 750D begins at the lower right corner of registration element 730. Figure 7IAt the location of gaze 750D at which the user's gaze is detected, computer system 700 changes the appearance of portion 730A, such as by changing the color of portion 730A to a darker color and / or changing the amount of light originating from portion 730A, to indicate that the user's gaze has been detected. Figure 7J At , as the computer system 700 continues to detect gaze 750D moving along gaze path 722, the computer system 700 changes the appearance of portion 730B, such as by changing the color of portion 730A to a darker color and / or changing the amount of light originating from portion 730B, to indicate that the user's gaze has been detected at a location corresponding to portion 730B. Figure 7K At , the computer system 700 has detected that the gaze 750D has moved completely (or nearly completely) around the registration element 730 along the gaze path 722, and has therefore updated the appearance of all of the portions 730A-730D, such as by additionally changing the color of the portions 730C-730D to a darker color and / or changing the amount of light originating from the portions 730C-730D, to indicate that the computer system 700 has detected that the user is gazing at positions corresponding to those respective portions. Because the computer system 700 has detected that the user is gazing at positions corresponding to all of the portions 730A-730D, that portion of the gaze registration is complete, and the computer system 700 proceeds to replace the registration element 730 with (e.g., shrink it to and / or morph it into) the target 714, as shown.

In some embodiments, the elements of registration element 740 (including elements 740A-740F) are spaced apart (e.g., at equal intervals or at unequal intervals). In some embodiments, the elements of registration element 740 (including elements 740A-740F) are arranged in a two-dimensional arrangement (e.g., a two-dimensional array or a two-dimensional grid). When the computer system 700 detects that the gaze of the user of the computer system 700 is directed to a corresponding position in the three-dimensional environment 712, the computer system 700 displays an indication 780 corresponding to the corresponding position of the user's gaze in the three-dimensional environment 712. The indication 780 corresponding to the position of the user's gaze in the three-dimensional environment 712 moves as the detected position of the user's gaze moves.

Further in response to the user's gaze determination 750E having been directed (e.g., continuously) at element 740A for greater than a threshold amount of time, the computer system moves (e.g., via an animated movement over time) highlight 742 from element 740A to element 740E, as shown in FIG. Figure 7N Moving highlight 742 to element 740E is intended to encourage and / or prompt a user of computer system 700 to move their gaze to element 740E, thereby enabling computer system 700 to capture additional gaze information regarding the user's gaze.

[0280] exist Figure 7O At , the computer system 700 detects that the user's gaze 750E moves past element 740C, and in response, displays an indication 780 corresponding to the corresponding location of the user's gaze in the three-dimensional environment 712 as partially at the location of element 740C (e.g., and partially not at the location of element 740C). In some embodiments, the indication 780 illuminates a portion (or all) of element 740C in the three-dimensional environment 712 (e.g., using simulated lighting, such as a simulated spotlight), while not illuminating other elements of the registration element 740. Figure 7O At , in response to the user's gaze 750E no longer being directed toward element 740A, computer system 700 begins to change (and / or restore) the appearance of element 740A (eg, changing the color back to a dark color, changing the shape, and / or changing the size).

Figure 7P At , the computer system 700 has detected that the user's gaze 750E is directed toward the element 740E for greater than a threshold amount of time, and in response, has changed the visual appearance of the element 740E (e.g., changed color to white (or another color), changed shape, and / or changed size). In some embodiments, the computer system 700 gradually changes the appearance of the element 740E over time upon detecting that the user's gaze 750E is directed toward the element 740E, thereby providing visual feedback to the user that their gaze is directed toward the corresponding element. Figure 7PAt , further in response to computer system 700 having detected that user's gaze 750E has been directed at element 740E for greater than a threshold amount of time, computer system 700 has moved (e.g., via an animated movement over time) highlight 742 from element 740E to element 740F. Moving highlight 742 to element 740F is intended to encourage and / or prompt the user of computer system 700 to move their gaze to element 740F, thereby enabling computer system 700 to capture additional gaze information about the user's gaze.

In some embodiments, when the computer system detects that the user's gaze is directed at a corresponding element that is not highlighted, the computer system 700 abandons gradually modifying the appearance of the corresponding element over time (e.g., only changing the appearance based on illuminating the corresponding element in the three-dimensional environment 712 using an indication 780 (e.g., using simulated lighting, such as a simulated spotlight)).
