[0002] The present disclosure generally relates to a computer system in communication with a display generating component, including but not limited to electronic devices that provide virtual reality and mixed reality experiences via a display, and one or more input devices that provide a computer-generated experience. [Background technology]

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

[0004] Some methods and interfaces for eye-tracking registration are cumbersome, inefficient, and limited. For example, systems that provide insufficient feedback for performing actions associated with eye-tracking registration, systems that require a series of inputs to achieve a desired result in an augmented reality environment, and systems that make manipulating virtual objects complex, tedious, and error-prone create a significant cognitive burden for users and detract from their experience with the virtual / augmented reality environment. In addition, these methods are unnecessarily time-consuming, thereby wasting computer system energy. This latter consideration is particularly important in battery-operated devices.

[0005] Thus, there is a need for a computer system having improved methods and interfaces for eye-tracking registration and for providing a user with a computer-generated experience that makes interaction with the computer system more efficient and intuitive for the user. Such methods and interfaces optionally complement or replace conventional methods for registering a user's gaze and providing a user with an extended reality experience. Such methods and interfaces reduce the number, extent, and / or type of inputs from the user by helping the user understand the connection between the input provided and the device response to that input, thereby creating a more efficient human-machine interface.

[0006] The above-mentioned drawbacks and other problems associated with user interfaces of computer systems 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 wristwatch or a head-mounted device). In some embodiments, the computer system has a touchpad. In some embodiments, the computer system has one or more cameras. In some embodiments, the computer system has a touch-sensitive display (also known as a "touch screen" or "touchscreen display"). In some embodiments, the computer system has one or more eye-tracking components. In some embodiments, the computer system has one or more hand-tracking components. In some embodiments, the computer system has one or more output devices in addition to the display generating components, the output devices including one or more tactile output generators and / or one or more audio output devices. In some embodiments, the computer system has a graphical user interface (GUI), one or more processors, memory, and one or more modules, programs, or instruction sets stored in the memory for performing a plurality of functions. In some embodiments, a user interacts with the GUI through stylus and / or finger contacts and gestures on a touch-sensitive surface, the 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 cameras and other movement sensors, and / or voice input as captured by one or more audio input devices.In some embodiments, the functions performed through the interactions optionally include image editing, drawing, presenting, word processing, creating spreadsheets, playing games, making phone calls, video conferencing, emailing, instant messaging, training support, digital photography, digital videography, web browsing, playing digital music, note taking, and / or playing digital videos, and executable instructions to perform those functions are optionally contained in a transient and / or non-transitory computer-readable storage medium or other computer program product configured to be executed by one or more processors.

[0007] There is a need for electronic devices with improved methods and interfaces for eye-tracking registration. Such methods and interfaces can complement or replace conventional methods for eye-tracking registration. Such methods and interfaces reduce the number, extent, and / or type of inputs from a user, creating a more efficient human-machine interface. Additionally, such methods and interfaces enable faster and more accurate eye-tracking registration. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges.

Figure 19 is a flow diagram of a method for user enrollment, according to various embodiments. The user interfaces of Figures 18A-18H are used to explain the process of Figure 19.

[0086] The processes described below enhance device usability and make user-device interfaces more efficient (e.g., by helping users provide appropriate inputs and reducing user errors when operating / interacting with the device) through various techniques, including providing improved visual feedback to the user, reducing the number of inputs required to perform an action, providing additional control options without cluttering the user interface with additional controls, performing an action without requiring further user input when a set of conditions is met, improving privacy and / or security, providing a more diverse, detailed, and / or realistic user experience while saving storage space, and / or additional techniques. These techniques also reduce power usage and improve device battery life by allowing users to use the device more quickly and efficiently. Saving battery power, and therefore weight, improves device ergonomics. These techniques also enable real-time communication and the use of fewer and / or less accurate sensors, resulting in more compact, lighter, and less expensive devices, and allowing devices to be used in a variety of lighting conditions. These techniques reduce energy use and thereby reduce the heat given off by the device, which is particularly important for wearable devices where a device that is well within the operating parameters for the device components may become uncomfortable for the user to wear if it is generating too much heat.

[0087] Furthermore, for methods described herein in which one or more steps are conditioned on one or more conditions being satisfied, it should be understood that the described method can be repeated in multiple iterations, such that over the course of the iterations, all of the conditions on which the method steps are conditioned are satisfied in different iterations of the method. For example, if a method requires performing a first step if a condition is satisfied and a second step if the condition is not satisfied, one skilled in the art will understand that the steps recited in the claim are repeated in a particular order until the conditions are satisfied and then no longer satisfied. Thus, a method described with one or more steps that depend on one or more conditions being satisfied can be rewritten as a method that is repeated until each condition recited in the method is satisfied. However, this is not required for system or computer-readable medium claims in which the system or computer-readable medium includes instructions for performing a conditional action based on the satisfaction of the corresponding one or more conditions, and thus can determine whether a contingency is met without explicitly repeating the method steps until all conditions on which the method steps are conditioned are satisfied. Those skilled in the art will also understand that, as with methods having conditional steps, the system or computer-readable storage medium may repeat the steps of the method as many times as necessary to ensure that all of the conditional steps have been performed.

[0088] 1A , an XR experience is provided to a user via an operating environment 100 that includes 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 touchscreen, 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 location sensor, a motion sensor, a speed sensor, etc.), and optionally one or more peripheral devices 195 (e.g., a consumer electronics device, a wearable device, etc.). In some embodiments, one or more of input device 125, output device 155, sensor 190, and peripheral device 195 are integrated with display generation component 120 (e.g., within a head-mounted or handheld device).

[0089] When describing an XR experience, various terms are used to distinguish between multiple related, yet distinct, environments that a user may sense and / or interact with (e.g., involving inputs detected by the computer system 101 that generates the XR experience that cause the computer system that generates the XR experience to generate audio, visual, and / or haptic feedback that corresponds to various inputs provided to the computer system 101). The following is a subset of these terms:

[0090] 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 through their senses, such as sight, touch, hearing, taste, and smell.

[0091] Extended reality: In contrast, an extended reality (XR) environment refers to a wholly or partially simulated environment that people sense and / or interact with through electronic systems. In XR, a subset of a person's physical movements or representations thereof are tracked, and one or more properties of one or more virtual objects simulated within the XR environment are adjusted accordingly to behave with at least one law of physics. For example, an XR system may detect the rotation of a person's head and adjust the graphical content and sound field presented to the person accordingly, in a manner similar to how such views and sounds change in a physical environment. In some situations (e.g., for accessibility reasons), adjustments to the characteristic(s) of a virtual object(s) in an XR environment may be made in response to the representation of a physical movement (e.g., a voice command). A person may sense and / or interact with an XR object using any one of their senses, including sight, sound, touch, taste, and smell. For example, a person may sense and / or interact with audio objects that create a 3D or spatial audio environment that provides the perception of a point audio source in 3D space. In another example, audio objects may enable audio transparency that selectively incorporates ambient sounds from the physical environment, with or without computer-generated audio. In some XR environments, a person may sense and / or interact with only audio objects.

[0092] Examples of XR include virtual reality and mixed reality.

[0093] Virtual Reality: A virtual reality (VR) environment refers to a simulated environment designed to be based entirely on computer-generated sensory input for one or more senses. A VR environment includes multiple virtual objects that a person can sense and / or interact with. For example, computer-generated images of trees, buildings, and avatars representing people 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 in the computer-generated environment and / or through a simulation of a subset of the person's physical movement within the computer-generated environment.

[0094] Mixed reality: A mixed reality (MR) environment refers to a simulated environment designed to incorporate sensory input from or representations of a physical environment in addition to including computer-generated sensory input (e.g., virtual objects), as opposed to a VR environment designed to be based entirely on computer-generated sensory input. On a virtual continuum, a mixed reality environment is anywhere between, but not including, a complete 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. Some electronic systems for presenting MR environments may also track location and / or orientation relative to the physical environment to allow virtual objects to interact with real objects (i.e., physical items from the physical environment or representations thereof). For example, the system may take into account movement so that a virtual tree appears stationary relative to the physical ground.

[0095] Examples of mixed reality include augmented reality and augmented virtuality.

[0096] 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 thereof. 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 the transparent or translucent display, whereby 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 that are representations of the physical environment. The system composites the images or videos with the virtual objects and presents the composite on the opaque display. The person uses the system to indirectly view the physical environment through the images or videos of the physical environment and perceive the virtual objects superimposed on the physical environment. As used herein, video of a physical environment shown on an opaque display is referred to as “pass-through video,” meaning that the system captures images of the physical environment using one or more image sensors and uses those images in presenting the AR environment on the opaque display. Alternatively, the system may include a projection system that projects virtual objects, e.g., as holograms, into the physical environment or onto a physical surface, such that a person using the system perceives the virtual objects superimposed on the physical environment. Augmented reality environments also refer to simulated environments in which a representation of the physical environment is transformed by computer-generated sensory information. For example, when providing pass-through video, the system may distort one or more sensor images to impose a selected perspective (e.g., viewpoint) different from the perspective captured by the imaging sensor. As another example, the representation of the physical environment may be distorted by graphically modifying (e.g., enlarging) portions thereof, thereby rendering the modified portions a non-photorealistic, altered version of the originally captured image. As a further example, the representation of the physical environment may be distorted by graphically removing or obscuring portions thereof.

[0097] Augmented Virtuality: An augmented virtuality (AV) environment refers to a simulated environment in which a virtual or computer-generated environment incorporates one or more sensory inputs from a physical environment. The sensory inputs may be representations of one or more characteristics of the physical environment. For example, an AV park may have virtual trees and virtual buildings, while people with faces are realistically recreated from images taken of physical people. As another example, virtual objects may adopt the shape or color of physical items imaged by one or more imaging sensors. As a further example, virtual objects may adopt shadows that match the position of the sun in the physical environment.

[0098] 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 a user via one or more display generating components (e.g., a display or pair of display modules providing stereoscopic content to different eyes of the same user) through a virtual viewport having a viewport boundary that defines the extent of the three-dimensional environment visible to the user via the one or more display generating components. In some embodiments, the area defined by the viewport boundary is smaller in one or more dimensions than the user's field of view (e.g., based on the user's field of view, the size, optical properties, or other physical characteristics of the one or more display generating components, and / or the location and / or orientation of the one or more display generating components relative to the user's eyes). In some embodiments, the area defined by the viewport boundary is larger in one or more dimensions than the user's field of view (e.g., based on the user's field of view, the size, optical properties, or other physical characteristics of the one or more display generating components, and / or the location and / or orientation of the one or more display generating components relative to the user's eyes). The viewport and viewport boundaries typically move as one or more display-generating components move (e.g., with the user's head in the case of a head-mounted device, or with the user's hands in the case of a handheld device such as a tablet or smartphone). The user's viewpoint determines what content is visible within the viewport; the viewpoint generally specifies a location and orientation relative to the three-dimensional environment; as the viewpoint shifts, the view of the three-dimensional environment also shifts within the viewport. In the case of a head-mounted device, the viewpoint is typically based on the location 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.In the case of a handheld or stationary device, the viewpoint shifts as the handheld or stationary device is moved and / or as the user's position relative to the handheld or stationary device changes (e.g., as the user moves toward, away from, above, below, to the right of, and / or to the left of the device). In a device that includes a display generation component with virtual pass-through, the portion of the physical environment that is visible (e.g., displayed and / or projected) through one or more display generation components typically moves with the display generation components (e.g., moves with the user's head in a head-mounted device, or moves with the user's hand in a handheld device such as a tablet or smartphone) as the user's viewpoint moves as the field of view of one or more cameras moves (and the appearance of one or more virtual objects displayed through the one or more display generation components is updated based on the user's viewpoint (e.g., the displayed position and pose of the virtual objects are updated based on the movement of the user's viewpoint). In the case of display generating components that have an optical pass-through, the portion of the physical environment that is visible through one or more display generating components (e.g., optically visible through one or more partially or fully transparent portions of the display generating components) is based on the user's view through the partially or fully transparent portions of the display generating components (e.g., moves with the user's head in the case of a head-mounted device, or moves with the user's hand in the case of a handheld device such as a tablet or smartphone), such that the user's viewpoint moves (and the appearance of the one or more virtual objects is updated based on the user's viewpoint) as the user's viewpoint moves through the partially or fully transparent portion(s) of the display generating components.

[0099] In some embodiments, a representation of the physical environment (e.g., displayed via a virtual or optical pass-through) can be partially or completely obscured by the virtual environment. In some embodiments, the amount of the virtual environment that is displayed (e.g., the amount of the physical environment that is not displayed) is based on the immersion level of the virtual environment (e.g., relative to the representation of the physical environment). For example, increasing the immersion level optionally causes more of the virtual environment to be displayed, replacing and / or obscuring more of the physical environment, and decreasing the immersion level optionally causes less of the virtual environment to be displayed, revealing portions of the physical environment that were not previously 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 less highlighted (e.g., dimmed, blurred, and / or displayed with increased transparency) than one or more second background objects, and one or more third background objects are suppressed from display. In some embodiments, the immersion level includes the relative extent to which the virtual content (e.g., the virtual environment and / or virtual content) displayed by the computer system obscures background content (e.g., content other than the virtual environment and / or virtual content) around / behind the virtual content, and optionally includes the number of items of background content displayed and / or the visual characteristics (e.g., color, contrast, and / or opacity) with which the background content is displayed, the angular range of the virtual content displayed via the display generating components (e.g., 60-degree content displayed at low immersion, 120-degree content displayed at medium immersion, or 180-degree content displayed at high immersion), and / or the percentage of the field of view displayed via the display generating components that is consumed by the virtual content (e.g., 33% of the field of view consumed by the virtual content at low immersion, 66% of the field of view consumed by the virtual content at medium immersion, or 100% of the field of view consumed by the virtual content at high immersion). In some embodiments, the background content is included in the background against which the virtual content is displayed (e.g., background content within a representation of the physical environment).In some embodiments, background content includes user interfaces (e.g., user interfaces generated by a computer system corresponding to an application), virtual objects (e.g., files or representations of other users generated by a computer system) that are not associated with or included in the virtual environment and / or virtual content, and / or real objects (e.g., pass-through objects that represent real objects in the physical environment around the user that are visible as displayed through the display generating components and / or that are visible through transparent or translucent components of the display generating components because the computer system does not obscure / prevent their visibility through the display generating components). In some embodiments, at a low immersion level (e.g., a first immersion level), background, virtual, and / or real objects are displayed in an unobscured manner. For example, a virtual environment at a low immersion level is optionally displayed simultaneously with background content, and the background content is optionally displayed at full brightness, color, and / or translucency. In some embodiments, at a higher immersion level (e.g., a second immersion level higher than the first immersion level), background, virtual, and / or real objects are displayed in an obscured manner (e.g., dimmed, blurred, or removed from the display). For example, a separate virtual environment having a high immersion level is displayed without simultaneously displaying background content (e.g., in full screen or fully immersive mode). As another example, a virtual environment displayed at an intermediate immersion level is simultaneously displayed with dimmed, blurred, or otherwise de-highlighted background content. In some embodiments, the visual characteristics of the background objects differ among the background objects. For example, at a particular immersion level, one or more first background objects are visually less highlighted (e.g., dimmed, blurred, and / or displayed with increased transparency) than one or more second background objects, and one or more third background objects are suppressed from display.In some embodiments, a null or zero level of immersion corresponds to the display of the virtual environment being stopped, and instead a representation of the physical environment (optionally along with one or more virtual objects, such as applications, windows, or virtual three-dimensional objects) is displayed 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 way to adjust immersion, improving usability of computer systems and making user-device interfaces more efficient.

[0100] Perspective-Locked Virtual Object: A virtual object is perspective-locked when the computer system displays the virtual object in the same location and / or position within the user's perspective, even as the user's perspective shifts (e.g., changes). In embodiments in which the computer system is a head-mounted device, the user's perspective is locked to the forward-facing orientation of the user's head (e.g., the user's perspective is at least a portion of the user's field of view when the user is looking straight ahead). Thus, the user's perspective remains fixed even as the user's line of sight moves without moving the user's head. In embodiments in which the computer system has a display generating component (e.g., a display screen) that can be repositioned relative to the user's head, the user's perspective is the augmented reality view being presented to the user on the display generating component of the computer system. For example, a perspective-locked virtual object that is displayed in the upper left corner of the user's perspective when the user's perspective is in a first orientation (e.g., the user's head is facing north) will continue to be displayed in the upper left corner of the user's perspective even if the user's perspective changes to a second orientation (e.g., the user's head is facing west). In other words, the location and / or position at which a viewpoint-locked virtual object is displayed in a user's viewpoint is independent of the user's position and / or orientation in the physical environment. In embodiments in which 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."

[0101] Environment-Locked Virtual Object: A virtual object is environment-locked (or "world-locked") when a computer system displays the virtual object at a location and / or position within a user's viewpoint that is based on (e.g., selected with reference to and / or anchored to) locations and / or objects within a three-dimensional environment (e.g., a physical environment or a virtual environment). As the user's viewpoint shifts, the locations and / or objects within the environment relative to the user's viewpoint change, resulting in the environment-locked virtual object appearing at a different location and / or position within the user's viewpoint. For example, an environment-locked virtual object locked to a tree directly in front of the user will appear centered within the user's viewpoint. If the user's viewpoint shifts to the right (e.g., the user's head is turned to the right) and the tree becomes more left-leaning in the user's viewpoint (e.g., the position of the tree in the user's viewpoint shifts), the environment-locked virtual object locked to the tree will appear more left-leaning in the user's viewpoint. In other words, the location and / or position at which the environment-locked virtual object appears within the user's viewpoint depends on the position and / or orientation of the location and / or 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 fixed to a fixed location and / or object in the physical environment) to determine a position at which to display an environment-locked virtual object in the user's viewpoint. The 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 moving portion of the environment (e.g., a vehicle, an animal, a person, or a representation of a part of the user's body that moves independent of the user's viewpoint, such as the user's hand, wrist, arm, or leg), so that the virtual object moves as the viewpoint or part of the environment moves in order to maintain a fixed relationship between the virtual object and the part of the environment.

[0102] In some embodiments, an environment-locked or viewpoint-locked virtual object exhibits delayed-following behavior, which reduces or delays the movement of the environment-locked or viewpoint-locked virtual object relative to the movement of a reference point that the virtual object is following. In some embodiments, when exhibiting delayed-following behavior, the computer system intentionally delays the movement of the virtual object when it detects movement of the reference point that the virtual object is following (e.g., a part of the environment, the viewpoint, or a point fixed relative to the viewpoint, such as a point between 5 and 300 cm from the viewpoint). For example, when the reference point (e.g., a part of the environment or the 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 or slows down its movement, at which point the virtual object begins to catch up with the reference point). In some embodiments, when the virtual object exhibits delayed-following behavior, the device ignores small amounts of movement of the reference point (e.g., ignores movement of the reference point that is less than a threshold amount, such as movement between 0 and 5 degrees or movement between 0 and 50 cm). For example, when the reference point (e.g., a portion of the environment or a viewpoint to which the virtual object is locked) moves by a first amount, the distance between the reference point and the virtual object increases (e.g., because the virtual object is displayed to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and when the reference point (e.g., a portion of the environment or a viewpoint to which the virtual object is locked) moves by a second amount greater than the first amount, the distance between the reference point and the virtual object initially increases (e.g., because the virtual object is displayed to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and then decreases as the amount of movement of the reference point increases beyond a threshold (e.g., a “delayed following” threshold) as 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, a virtual object maintaining a substantially fixed position relative to a reference point includes the virtual object being displayed within a threshold distance (e.g., 1, 2, 3, 5, 15, 20, 50 cm) of the reference point in one or more dimensions (e.g., above / below, left / right, and / or forward / backward relative to the position of the reference point).

[0103] In some embodiments, spatial media includes spatial visual media and / or spatial audio. In some embodiments, spatial capture is capture of spatial media. In some embodiments, spatial visual media (also referred to as stereoscopic media) (e.g., spatial image and / or spatial video) is media that includes two different images or sets of images representing two perspectives of the same or overlapping field of view for simultaneous display. A first image representing the first perspective is presented to a first eye of a viewer, and a second image representing a second perspective different from the first perspective is simultaneously presented to a second eye of the viewer. The first and second images have the same or overlapping field of view. In some embodiments, a computer system displays the first image via a first display positioned to be viewed by the first eye of the viewer and simultaneously displays the second image via a second display different from the first display positioned to be viewed by the second eye of the viewer. In some embodiments, the first and second images, when viewed together, create a depth effect, providing 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 a first eye of a viewer, and a second video representing a second perspective different from the first perspective is simultaneously presented to a second eye of the viewer. The first and second videos have the same or overlapping fields of view. In some embodiments, the first and second videos, when viewed together, create a depth effect, providing the viewer with a depth perception of the video content. In some embodiments, a spatial audio experience in headphones is created by manipulating sounds in two audio channels (e.g., left and right) of the headphones so that they resemble directional sounds arriving in the ear canal. For example, headphones can reproduce spatial audio signals that simulate the soundscape around the listener (also referred to as a user). Effective spatial sound reproduction can render sounds so that the listener perceives them as coming from a location in the soundscape outside the listener's head, just as the listener would experience the sounds if encountered in the real world.

[0104] The shape of a listener's ear, particularly the outer ear (pinna), has a significant impact on the sound that reaches the listener's eardrum from the sound source. A spatial audio sound experience is possible by considering the effects of the listener's pinna, the listener's head, and / or the listener's torso on the sound entering the listener's ear canal. The shape of the user's ear is optionally determined by using a three-dimensional scanning device that generates a three-dimensional model of at least a portion of the visible portion of the user's ear. This shape is optionally used to generate filters for generating the spatial audio experience. In some embodiments, spatial audio is sound that has been filtered so that a listener of the sound perceives the sound as coming from one or more directions and / or locations in three-dimensional space (e.g., above, below, and / or in front of the listener).

[0105] An example of such a filter is a head-related transfer function (HRTF) filter. These filters are used to provide an effect similar to the way the human ear, head, and torso filters produce sound. When the shape of a listener's ears is known, personalized filters (e.g., personalized HRTF filters) can be generated so that the sound experienced by that listener through headphones (e.g., in-ear headphones, on-ear headphones, and / or over-ear headphones) is more realistic. In some embodiments, because listeners' ears may have different shapes, two filters are generated, one filter for each ear, so that each ear of the listener has a corresponding personalized filter (e.g., personalized HRTF filter).

[0106] In some embodiments, the HRTF filter contains 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 may be selected from a database of HRTFs previously determined for users with similar anatomical characteristics. In some embodiments, the personalized HRTF filter may be generated by numerical modeling based on the shape of the listener's ear. One or more processors of the computer system optionally apply the personalized HRTF filter for the listener to an audio input signal to generate a spatial input signal for playback by headphones connected (e.g., wirelessly or wired) to the computer system.

[0107] Hardware: There are many different types of electronic systems that allow a person to sense and / or interact with various XR environments. Examples include head-mounted systems, projection-based systems, head-up displays (HUDs), vehicle windshields with integrated display capabilities, windows with integrated display capabilities, displays formed as lenses designed to be placed over a person's eyes (e.g., contact lenses), headphones / earphones, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablets, and desktop / laptop computers. A head-mounted system may include speakers and / or other audio output devices integrated into the head-mounted system to provide audio output. A head-mounted system may have one or more speaker(s) 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. The head-mounted system may have a transparent or translucent display rather than an opaque display. The 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, laser-scanned light source, or any combination of these technologies. The medium may be a light guide, a holographic medium, an optical combiner, an optical reflector, or any combination thereof. In one embodiment, the transparent or translucent display may be configured to be selectively opaque. A projection-based system may employ retinal projection technology that projects a graphical image onto a person's retina. The projection system may also be configured to project virtual objects into the physical environment, for example, as a hologram or onto a physical surface.In some embodiments, controller 110 is configured to manage and coordinate the XR experience for the user. In some embodiments, controller 110 includes a suitable combination of software, firmware, and / or hardware. Controller 110 is described in more detail below with respect to FIG. 2. In some embodiments, controller 110 is a computing device that is local or remote to scene 105 (e.g., the physical environment). For example, controller 110 is a local server located within scene 105. In another example, controller 110 is a remote server (e.g., a cloud server, a central server, etc.) located outside scene 105. In some embodiments, controller 110 is communicatively coupled to display generation component 120 (e.g., an HMD, a display, a projector, a touchscreen, 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 contained within the housing (e.g., physical housing) of one or more of the display generating component 120 (e.g., an HMD or a portable electronic device including a display and one or more processors), one or more of the input devices 125, one or more of the output devices 155, one or more of the sensors 190, and / or one or more of the peripheral devices 195, or shares the same physical housing or support structure as one or more of the foregoing.

[0108] In some embodiments, display generation component 120 is configured to provide an XR experience (e.g., at least a visual component of the XR experience) to a user. In some embodiments, display generation component 120 includes a suitable combination of software, firmware, and / or hardware. Display generation component 120 is described in more detail below with respect to FIG. 3. In some embodiments, the functionality of controller 110 is provided by and / or combined with display generation component 120.

[0109] According to some embodiments, the display generation component 120 provides an XR experience to the user while the user is virtually and / or physically present in the scene 105.

[0110] In some embodiments, the display generating component is worn on a part of the user's body (e.g., on their head, their hand, etc.). Thus, display generating component 120 includes one or more XR displays provided for displaying XR content. For example, in various embodiments, display generating component 120 surrounds the user's field of view. In some embodiments, display generating component 120 is a handheld device (e.g., a smartphone or tablet) configured to present XR content, where the user holds the device with a display pointed toward the user's field of view and a camera pointed toward scene 105. In some embodiments, the handheld device is optionally located within a housing worn on the user's head. In some embodiments, the handheld device is optionally located on a support (e.g., a tripod) in front of the user. In some embodiments, display generating component 120 is an XR chamber, housing, or room configured to present XR content without the user wearing or holding display generating 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) may 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 illustrating interactions with XR content that are triggered based on interactions occurring in the space in front of a handheld or tripod-mounted device may be implemented similarly to an HMD in which the interactions occur in the space in front of the HMD and the XR content responses are displayed via the HMD. Similarly, a user interface illustrating interactions with XR content that are triggered based on movement of a handheld or tripod-mounted device relative to the physical environment (e.g., scene 105 or a part of the user's body (e.g., the user's eye(s), head, or hands)) may be implemented similarly to an HMD in which the movement is caused by movement of the HMD relative to the physical environment (e.g., scene 105 or a part of the user's body (e.g., the user's eye(s), head, or hands)).

[0111] While relevant features of operating environment 100 are shown in FIG. 1A, those skilled in the art will understand from this disclosure that various other features are not shown for the sake of brevity and so as not to obscure more relevant aspects of the exemplary embodiments disclosed herein.

[0112] 1A-1P illustrate various examples of computer systems that can be used to perform the methods and provide audio, visual, and / or haptic feedback as part of the user interfaces described herein. In some embodiments, the computer system optionally includes one or more display generation components (e.g., first and second display assemblies 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a and 11.1.1-104b) for displaying representations of virtual elements and / or the physical environment to a user of the computer system, the representations being generated based on detected events and / or user input detected by the computer system. The user interface generated by the computer system is optionally corrected by one or more corrective lenses 11.3.2-216, optionally removably attached to one or more of the optical modules, to enable users who otherwise correct their vision using glasses or contact lenses to more easily view the user interface. While many user interfaces shown herein show a single view of the user interface, the user interface in the HMD is optionally displayed using two optical modules (e.g., first and second display assemblies 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a and 11.1.1-104b), one for the user's right eye and a different one for the user's left eye, with slightly different images presented to the two different eyes to create the illusion of stereoscopic depth, and the single view of the user interface is typically either a right-eye or left-eye view, and the depth effect is explained in text or using other schematic diagrams or views.In some embodiments, the computer system includes one or more external displays (e.g., display assembly 1-108) for displaying status information of the computer system to a user of the computer system (when the computer system is not being worn) and / or other people near the computer system, optionally generated based on detected events and / or user input detected by the computer system. In some embodiments, the computer system includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback, optionally generated based on detected events and / or user input detected by the computer system. In some embodiments, the computer system includes one or more input devices for detecting inputs, such as one or more sensors (e.g., sensor assembly 1-356 and / or one or more sensors in FIG. 1I) for detecting information about the physical environment of a device that can be used (optionally in conjunction with one or more illuminators, such as the illuminators described in FIG. 1I) to generate a digital pass-through image, capture visual media (e.g., photographs and / or videos) corresponding to the physical environment, or determine the pose (e.g., position and / or orientation) of physical objects and / or surfaces within the physical environment, so that virtual objects can be positioned based on the detected pose of the physical objects and / or surfaces. In some embodiments, the computer system includes one or more input devices for detecting input, such as one or more sensors for detecting hand position and / or movement (e.g., sensor assembly 1-356 and / or one or more sensors in FIG. 1I), which can be used (optionally in conjunction with one or more illuminators, such as illuminator 6-124 shown in FIG. 1I) to determine when one or more air gestures are performed.In some embodiments, the computer system includes one or more input devices for detecting input, such as one or more sensors for detecting eye movement (e.g., the eye tracking and gaze tracking sensors of FIG. 1I ), which may be used (optionally in conjunction with one or more lights, such as light 11.3.2-110 of FIG. 1O ) to determine attention or gaze position and / or gaze movement, which may optionally be used to detect gaze-only input based on gaze movement and / or dwell. A combination of the various sensors described above may be used to determine a user's facial expressions and / or hand movements for use in generating an avatar or representation of the user, such as an anthropomorphic avatar or representation for use in a real-time communication session, the avatar having facial expressions, hand movements, and / or body movements based on or similar to the detected facial expressions, hand movements, and / or body movements of the user of the device. Gaze and / or attention information is optionally combined with hand tracking information to determine interactions between the user and one or more user interfaces based on direct and / or indirect inputs, such as air gestures or inputs using one or more hardware input devices, such as one or more buttons (e.g., first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328), knobs (e.g., first button 1-128, button 11.1.1-114, and / or dial or button 1-328), digital crowns (e.g., pressable and twistable or rotatable first button 1-128, button 11.1.1-114, and / or dial or button 1-328), trackpads, touchscreens, keyboards, mice, and / or other input devices.One or more buttons (e.g., first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328) are optionally used to perform system operations such as re-centering content within the three-dimensional environment visible to the device user, displaying a home user interface for launching an application, initiating a real-time communication session, or initiating the display of a virtual three-dimensional background. The knob or digital crown (e.g., a first button 1-128, button 11.1.1-114, and / or a dial or button 1-328 that is depressible and twistable or rotatable) is optionally rotatable to adjust parameters of the visual content, such as the immersion level of the virtual three-dimensional environment (e.g., the degree to which the virtual content occupies the user's viewport into the three-dimensional environment), or other parameters associated with the three-dimensional environment and the virtual content displayed via the optical modules (e.g., first and second display assemblies 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a and 11.1.1-104b).

[0113] 1B shows a front, top, and perspective view of an example head-mountable display (HMD) device 1-100 configured to be worn by a user and provide virtual and altered / mixed reality (VR / AR) experiences. The HMD 1-100 can include a display unit 1-102 or assembly, an electronic strap assembly 1-104 connected to and extending from the display unit 1-102, and a band assembly 1-106 secured at either end to the electronic strap assembly 1-104. The electronic strap assembly 1-104 and band 1-106 can be part of a retention assembly configured to wrap around a user's head to hold the display unit 1-102 against the user's face.

[0114] In at least one example, the band assembly 1-106 can include a first band 1-116 configured to wrap around the back of the user's head and a second band 1-117 configured to extend over the top of the user's head. The second strap can extend between the first electronic strap 1-105a and the second electronic strap 1-105b of the electronic strap assembly 1-104, as shown. The strap assembly 1-104 and the band assembly 1-106 can be part of a fastening mechanism that extends rearward from the display unit 1-102 and is configured to hold the display unit 1-102 against the user's face.

[0115] In at least one example, the anchoring mechanism includes a first electronics strap 1-105a including a first proximal end 1-134 coupled to the display unit 1-102, e.g., a housing 1-150 of the display unit 1-102, and a first distal end 1-136 opposite the first proximal end 1-134. The anchoring mechanism can also include a second electronics strap 1-105b including a second proximal end 1-138 coupled to the housing 1-150 of the display unit 1-102, and a second distal end 1-140 opposite the second proximal end 1-138. The anchoring mechanism can also include a first band 1-116 including a first end 1-142 coupled to the first distal end 1-136 and a second end 1-144 coupled to the second distal end 1-140, and a second band 1-117 extending between the first electronic strap 1-105a and the second electronic strap 1-105b. The straps 1-105a-b and the band 1-116 can be coupled via a connection mechanism or assembly 1-114. In at least one example, the second band 1-117 includes a first end 1-146 coupled to the first electronic strap 1-105a between a first proximal end 1-134 and a first distal end 1-136, and a second end 1-148 coupled to the second electronic strap 1-105b between a second proximal end 1-138 and a second distal end 1-140.

[0116] In at least one example, the first and second electronic straps 1-105a-b include plastic, metal, or other structural material that forms the shape of the substantially rigid straps 1-105a-b. In at least one example, the first and second bands 1-116, 1-117 are formed from a resilient, flexible material including woven fabric, rubber, etc. The first and second bands 1-116, 1-117 can be flexible to conform to the shape of a user's head when wearing the HMD 1-100.

[0117] In at least one example, one or more of the first and second electronic straps 1-105a-b can define an internal strap volume and can include one or more electronic components disposed within the internal strap volume. In one example, as shown in FIG. 1B, the first electronic strap 1-105a can include an electronic component 1-112. In one example, the electronic component 1-112 can include a speaker. In one example, the electronic component 1-112 can include a computing component such as a processor.

[0118] In at least one example, the housing 1-150 defines a first, forward-facing opening 1-152. The display assembly 1-108 is disposed to block the first opening 1-152 from view when the HMD 1-100 is assembled, and therefore the forward-facing opening is labeled 1-152 with a dotted line in FIG. 1B . The housing 1-150 may also define a rear-facing second opening 1-154. The housing 1-150 also defines an interior volume between the first opening 1-152 and the second opening 1-154. In at least one example, the HMD 1-100 includes a display assembly 1-108, which may include a front cover and a display screen (shown in other figures) disposed within or across the front opening 1-152 to block the front opening 1-152. In at least one example, the display screen of the display assembly 1-108, as well as the entire display assembly 1-108, has a curvature configured to follow the curvature of the user's face. The display screen of the display assembly 1-108 can curve to complement the user's facial features and the overall curvature from one side of the face to the other, e.g., from left to right and / or top to bottom when the display unit 1-102 is pressed, as shown.

[0119] In at least one example, the housing 1-150 can define a first aperture 1-126 between the first opening 1-152 and the second opening 1-154, and a second aperture 1-130 between the first opening 1-152 and the second opening 1-154. The HMD 1-100 can also include a first button 1-128 disposed in the first aperture 1-126 and a second button 1-132 disposed in the second aperture 1-130. The first and second buttons 1-128, 1-132 can be depressible through the respective apertures 1-126, 1-130. In at least one example, the first button 1-126 and / or the second button 1-132 can be a twistable dial and a depressible button. In at least one example, the first button 1-128 is a depressible and twistable dial button, and the second button 1-132 is a depressible button.

[0120] FIG. 1C shows a rear perspective view of the HMD 1-100. The HMD 1-100 can include a light seal 1-110 extending rearward from a housing 1-150 of the display assembly 1-108 around the periphery of the housing 1-150, as shown. The light seal 1-110 can be configured to extend from the housing 1-150 to the user's face around the user's eyes to block external light from being seen. In one example, the HMD 1-100 can include first and second display assemblies 1-120a, 1-120b disposed at or within a rearward second opening 1-154 defined by the housing 1-150 and / or disposed within an interior volume of the housing 1-150 and configured to project light through the second opening 1-154. In at least one example, each display assembly 1-120a-b can include a respective display screen 1-122a, 1-122b configured to project light rearward through the second opening 1-154 toward the user's eyes.

[0121] In at least one example, with reference to both FIG. 1B and FIG. 1C , the display assembly 1-108 can be a front-facing display assembly including a display screen configured to project light in a first, forward direction, and the rear-facing display screens 1-122a-b can be configured to project light in a second, rearward direction opposite the first direction. As described above, the light seal 1-110 can be configured to block light outside the HMD 1-100, including light projected by the front-facing display screen of the display assembly 1-108 shown in the front perspective view of FIG. 1B, from reaching the user's eyes. In at least one example, the HMD 1-100 can also include a curtain 1-124 that blocks a second opening 1-154 between the housing 1-150 and the rear-facing display assemblies 1-120a-b. In at least one example, the curtain 1-124 can be elastic or at least partially elastic.

[0123] 1D shows an exploded view of an example of an HMD 1-200 including various portions or components separated according to modularity and selective coupling of those components. For example, the HMD 1-200 can include a band 1-216 that can be selectively coupled to first and second electronic straps 1-205a, 1-205b. The first anchoring strap 1-205a can include a first electronic component 1-212a, and the second anchoring strap 1-205b can include a second electronic component 1-212b. In at least one example, the first and second straps 1-205a-b can be removably coupled to the display unit 1-202.

[0124] Additionally, the HMD 1-200 may include a light seal 1-210 configured to be removably coupled to the display unit 1-202. The HMD 1-200 may also include lenses 1-218 that may be removably coupled to the display unit 1-202, for example, on first and second display assemblies including a display screen. The lenses 1-218 may include customized prescription lenses configured for vision correction. As noted, each component shown in the exploded view of FIG. 1D and described above may be removably coupled, attached, reattached, or interchangeable to update or replace components for different users. For example, bands such as band 1-216, light seals such as light seal 1-210, lenses such as lens 1-218, and electronic straps such as straps 1-205a-b may be interchangeable depending on the user, such that these components are customized to fit and accommodate individual users of the HMD 1-200.

[0133] FIG. 1G shows a perspective exploded view of a front cover assembly 3-100 of an HMD device described herein, such as the front cover assembly 3-1 of the HMD 3-100 shown in FIG. 1G, or any other HMD device shown and described herein. The front cover assembly 3-100 shown in FIG. 1G can include a transparent or translucent cover 3-102, a shroud 3-104 (or "canopy"), an adhesive layer 3-106, a display assembly 3-108 including a lenticular lens panel or array 3-110, and structural trim 3-112. The adhesive layer 3-106 can bond the shroud 3-104 and / or the transparent cover 3-102 to the display assembly 3-108 and / or the trim 3-112. The trim 3-112 can bond various components of the front cover assembly 3-100 to the frame or chassis of the HMD device.

[0134] In at least one example, as shown in FIG. 1G, a display assembly 3-108 including a transparent cover 3-102, a shroud 3-104, and a lenticular lens array 3-110 can be curved to accommodate the curvature of a user's face. The transparent cover 3-102 and the shroud 3-104 can be curved in two or three dimensions, for example, vertically in the Z direction in or out of the ZX plane and horizontally in the X direction in or out of the ZX plane. In at least one example, the display assembly 3-108 can include a display panel having pixels configured to project light through the lenticular lens array 3-110 and the shroud 3-104 and the transparent cover 3-102. The display assembly 3-108 can be curved in at least one direction, for example, horizontally, to accommodate the curvature of a user's face from one side (e.g., left side) to the other side (e.g., right side) of the face. In at least one example, shown and described in more detail in subsequent figures, each layer or component of the display assembly 3-108, which may include the lenticular lens array 3-110 and the display layer, can be curved horizontally in a similar or concentric manner to accommodate the curvature of the user's face.

[0135] In at least one example, the shroud 3-104 can include a transparent or translucent material through which the display assembly 3-108 projects light. In one example, the shroud 3-104 can include one or more opaque portions, such as opaque ink prints or other opaque film portions, on a rear surface of the shroud 3-104. The rear surface can be the surface of the shroud 3-104 that faces the user's eyes when the HMD device is worn. In at least one example, the opaque portion can be on a front surface of the shroud 3-104 opposite the rear surface. In at least one example, the one or more opaque portions of the shroud 3-104 can include a peripheral portion that visually obscures any components around the perimeter of the display screen of the display assembly 3-108. In this manner, the opaque portions of the shroud hide any other components, including electronic components, structural components, etc., of the HMD device that would otherwise be visible through the transparent or translucent cover 3-102 and / or shroud 3-104.

[0136] In at least one example, the shroud 3-104 can define one or more aperture transparent portions 3-120 through which sensors can transmit and receive signals. In one example, the portions 3-120 are apertures through which sensors can extend or transmit and receive signals. In one example, the portions 3-120 are transparent portions, or portions that are more transparent than the surrounding translucent or opaque portions of the shroud, through which sensors can transmit and receive signals through the shroud and through the transparent cover 3-102. In one example, the sensors can include a camera, an IR sensor, a LUX sensor, or any other visual or non-visual environmental sensor of the HMD device.

[0137] Any of the features, components, and / or parts shown in Figure 1G, including their arrangement and configuration, alone or in any combination, may be included in any of the other example devices, features, components, and parts described herein. Similarly, any of the features, components, and / or parts shown and described herein, including their arrangement and configuration, alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1G.

[0138] 1H shows an exploded view of an example of an HMD device 6-100. The HMD device 6-100 can include a sensor array or system 6-102 including one or more sensors, cameras, projectors, etc. attached to one or more components of the HMD 6-100. In at least one example, the sensor system 6-102 can include a bracket 1-338 to which one or more sensors of the sensor system 6-102 can be secured / fixed.

[0139] FIG. 1I illustrates a portion of an HMD device 6-100, including a front transparent cover 6-104 and a sensor system 6-102. The sensor system 6-102 can include multiple different sensors, emitters, and receivers, including cameras, IR sensors, projectors, and the like. The transparent cover 6-104 is shown in front of the sensor system 6-102 to illustrate the relative positions of the various sensors and emitters and the orientation of each sensor / emitter in the system 6-102. As referenced herein, terms such as "sideways," "sideways," "horizontal," and similar terms refer to orientations or directions as indicated by the X-axis shown in FIG. 1J. Terms such as "vertical," "upper," "lower," and similar terms refer to orientations or directions as indicated by the Z-axis shown in FIG. 1J. Terms such as "forward," "rearward," "forward," and "rearward," and similar terms refer to orientations or directions as indicated by the Y-axis shown in FIG. 1J.

[0140] In at least one example, a transparent cover 6-104 can define the front exterior surface of the HMD device 6-100, and a sensor system 6-102 including various sensors and their components can be disposed behind the cover 6-104 in the Y axis / direction. The cover 6-104 can be transparent or translucent to allow light, both detected by and emitted by the sensor system 6-102, to pass through the cover 6-104.

[0141] As discussed elsewhere herein, the HMD device 6-100 may include one or more controllers including a processor for electrically coupling the various sensors and emitters of the sensor system 6-102 with other electronic devices, such as one or more motherboards, processing units, and display screens. Additionally, as described in more detail below with reference to other figures, the various sensors, emitters, and other components of the sensor system 6-102 may be coupled to various structural frame members, brackets, etc. of the HMD device 6-100 that are not shown in FIG. 1I. For clarity of illustration, FIG. 1I shows the components of the sensor system 6-102 unattached from and electrically uncoupled from other components.

[0142] In at least one example, the device can include one or more controllers having a processor configured to execute instructions stored on a memory component electrically coupled to the processor, the instructions including, or capable of being executed by, one or more algorithms for self-correcting the various camera angles and positions described herein over time with use as the initial position, angle, or orientation of the camera is bumped or distorted due to an unintentional drop event or other event.

[0143] In at least one example, the sensor system 6-102 can include one or more scene cameras 6-106. The system 6-102 can include two scene cameras 6-106 disposed on either side of the bridge or arch of the nose of the HMD device 6-100, such that each of the two cameras 6-102 approximately corresponds to the position of the user's left and right eyes behind the cover 6-103. In at least one example, the scene cameras 6-106 are oriented generally forward in the Y direction to capture images in front of the user while the HMD 6-100 is in use. In at least one example, the scene cameras are color cameras and provide images and content for MR video pass-through to a display screen facing the user's eyes when using the HMD device 6-100. The scene cameras 6-106 can also be used for environment and object reconstruction.

[0144] In at least one example, the sensor system 6-102 may include a first depth sensor 6-108 oriented generally forward in the Y direction. In at least one example, the first depth sensor 6-108 may be used for environment and object reconstruction and hand and body tracking of the user. In at least one example, the sensor system 6-102 may include a second depth sensor 6-110 centrally disposed along the width of the HMD device 6-100 (e.g., along the X axis). For example, the second depth sensor 6-110 may be positioned in alignment with the center bridge or feature above the user's nose when wearing the HMD 6-100. In at least one example, the second depth sensor 6-110 may be used for environment and object reconstruction and hand and body tracking. In at least one example, the second depth sensor may include a LIDAR sensor.

[0145] In at least one example, the sensor system 6-102 can include a generally forward-facing depth projector 6-112 for projecting electromagnetic waves, e.g., in the form of a predetermined pattern of light dots, into and within a field of view of, or including and beyond, the user and / or scene camera 6-106. In at least one example, the depth projector can project electromagnetic waves of light in the form of a dot light pattern that reflects off objects and returns to the depth sensors described above, including the depth sensors 6-108, 6-110. In at least one example, the depth projector 6-112 can be used for environment and object reconstruction and hand and body tracking.

[0146] In at least one example, the sensor system 6-102 may include downward-facing cameras 6-114 having fields of view directed generally downward relative to the HMD device 6-100 in the Z-axis. 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 may be used for hand and body tracking, headset tracking, and facial avatar detection and creation to display a user avatar on the forward-facing display screen of the HMD device 6-100 as described elsewhere herein. The downward-facing cameras 6-114 may be used to capture facial expressions and movements of the user below the HMD device 6-100, including, for example, the cheeks, mouth, and chin.

[0147] In at least one example, the sensor system 6-102 may include chin cameras 6-116. In at least one example, the chin cameras 6-116 are disposed on the left and right sides of the HMD device 6-100 as shown and may be used for hand and body tracking, headset tracking, and facial avatar detection and creation to display a user avatar on the forward-facing display screen of the HMD device 6-100 as described elsewhere herein. The chin cameras 6-116 may be used to capture the expressions and movements of the user's face below the HMD device 6-100, including, for example, the user's chin, cheeks, mouth, and jaw. For hand and body tracking, headset tracking, and facial avatar,

[0148] In at least one example, the sensor system 6-102 can include a side camera 6-118. The side camera 6-118 can be oriented to capture left and right side views in the X-axis or direction relative to the HMD device 6-100. In at least one example, the side camera 6-118 can be used for hand and body tracking, headset tracking, and facial avatar detection and reconstruction.

[0149] In at least one example, the sensor system 6-102 can include multiple eye tracking and gaze tracking sensors for determining the identity, status, and gaze direction of a user's eyes during and / or before use. In at least one example, the eye / gaze tracking sensors can include nose-eye cameras 6-120 disposed on either side of and adjacent to the user's nose when the HMD device 6-100 is worn. The eye / gaze sensors can also include under-eye cameras 6-122 disposed below each user's eye for capturing eye images for facial avatar detection and creation, gaze tracking, and iris identification functions.

[0150] In at least one example, the sensor system 6-102 includes an infrared illuminator 6-124 directed outward from the HMD device 6-100 to illuminate the external environment and any objects therein with IR light for IR detection by one or more IR sensors of the sensor system 6-102. In at least one example, the sensor system 6-102 can include a flicker sensor 6-126 and an ambient light sensor 6-128. In at least one example, the flicker sensor 6-126 can detect the overhead light refresh rate to avoid display flicker. In one example, the infrared illuminator 6-124 can include a light-emitting diode and can be used, among other things, in low-light environments to illuminate a user's hands and other objects in low light for detection by the infrared sensors of the sensor system 6-102.

[0151] In at least one example, multiple sensors including a scene camera 6-106, a downward-facing camera 6-114, a chin 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 sizing for better hand tracking and object recognition and tracking capabilities of the HMD device 6-100. In at least one example, the downward-facing camera 6-114, chin camera 6-116, and side camera 6-118 described above and shown in FIG. 1I can be wide-angle cameras capable of operating in the visible and infrared spectrum. In at least one example, these cameras 6-114, 6-116, 6-118 can operate with only black and white light detection to simplify image processing and increase sensitivity.

[0152] Any of the features, components, and / or parts shown in Figure 1I, including their arrangements and configurations, alone or in any combination, may be included in any of the other example devices, features, components, and parts shown in Figures 1J-1L and described herein. Similarly, any of the features, components, and / or parts shown and described with reference to Figures 1J-1L, including their arrangements and configurations, alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1I.

[0153] 1J shows 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. In at least one example, the sensors 6-203 of the sensor system 6-202 can be disposed around the periphery of the HDM 6-200 such that the sensors 6-203 are disposed outwardly around the periphery of the display region or area 6-232 so as not to obstruct the view of the displayed light. In at least one example, the sensors can be disposed behind the shroud 6-204 and aligned with a transparent portion of the shroud to allow the sensors and projector to pass light back and forth through the shroud 6-204. In at least one example, an opaque ink or other opaque material or film / layer can be disposed on the shroud 6-204 around the display area 6-232 to obscure components of the HMD 6-200 outside of the display area 6-232 other 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 shroud 6-204 allows light to pass through it from the display (e.g., within the display area 6-232), but not radially outward from the display area around the outer periphery of the shroud 6-204.

[0154] In some examples, the shroud 6-204 includes a transparent portion 6-205 and an opaque portion 6-207, as described above and elsewhere herein. In at least one example, the opaque portion 6-207 of the shroud 6-204 can define one or more transparent areas 6-209 through which the sensors 6-203 of the sensor system 6-202 can send and receive signals. In the illustrated example, the sensors 6-203 of the sensor system 6-202, which transmit and receive signals through the shroud 6-204, or more specifically through the transparent region 6-209 of (or defined by) the opaque portion 6-207 of the shroud 6-204, may include sensors the same as or similar to those shown in the example of FIG. 1I, such as depth sensors 6-108 and 6-110, a depth projector 6-112, first and second scene cameras 6-106, first and second downward-facing cameras 6-114, first and second side cameras 6-118, and first and second infrared illuminators 6-124. These sensors are also shown in the examples of FIGS. 1K and 1L. Other sensors, sensor types, numbers of sensors, and their relative positions may be included in one or more other examples of the HMD.

[0155] Any of the features, components, and / or parts shown in Figure 1J, including their arrangements and configurations, either alone or in any combination, may be included in any of the other example devices, features, components, and parts shown in Figure 1I and Figures 1K-1L and described herein. Similarly, any of the features, components, and / or parts shown and described with reference to Figure 1I and Figures 1K-1L, including their arrangements and configurations, either alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1J.

[0156] FIG. 1K shows a front view of a portion of an example HMD device 6-300, including a display 6-334, brackets 6-336, 6-338, and a frame or housing 6-330. The example shown in FIG. 1K does not include a front cover or shroud, so as to show the brackets 6-336, 6-338. For example, the shroud 6-204 shown in FIG. 1J includes an opaque portion 6-207 that visually covers / blocks the view of anything outside (e.g., radially / circumferentially outward) of the display / viewing area 6-334, including the sensor 6-303 and bracket 6-338.

[0157] 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 their angles relative to one another. For example, the tolerance on the mounting angle between the two scene cameras 6-306 can be 0.5 degrees or less, e.g., 0.3 degrees or less. To achieve and maintain such tight tolerances, in one example, the scene camera 6-306 can be mounted to the bracket 6-338 rather than the shroud. The bracket can include a cantilever arm to which the scene camera 6-306 and other sensors of the sensor system 6-302 can be mounted such that their position and orientation remain undeformed in the event of a drop event by the user that results in any deformation of the other brackets 6-226, the housing 6-330, and / or the shroud.

[0158] Any of the features, components, and / or parts shown in Figure 1K, including their arrangements and configurations, alone or in any combination, may be included in any of the other example devices, features, components, and parts shown in Figures 1I-1J and 1L and described herein. Similarly, any of the features, components, and / or parts shown and described with reference to Figures 1I-1J and 1L, including their arrangements and configurations, alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1K.

[0159] FIG. 1L shows a bottom view of an example HMD 6-400 including a front display / cover assembly 6-404 and a sensor system 6-402. The sensor system 6-402 can be similar to other sensor systems described above and elsewhere herein, including with reference to FIGS. 1I-1K. In at least one example, the chin camera 6-416 can face downward to capture images of the user's lower facial features. In one example, the chin camera 6-416 can be directly coupled to a frame or housing 6-430 or to one or more internal brackets directly coupled to the illustrated frame or housing 6-430. The frame or housing 6-430 can include one or more apertures / openings 6-415 through which the chin camera 6-416 can send and receive signals.

[0160] Any of the features, components, and / or parts shown in Figure 1L, including their arrangements and configurations, alone or in any combination, may be included in any of the other example devices, features, components, and parts shown in Figures 1I-1K and described herein. Similarly, any of the features, components, and / or parts shown and described with reference to Figures 1I-1K, including their arrangements and configurations, alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1L.

[0161] 1M shows a rear perspective view of an interpupillary distance (IPD) adjustment system 11.1.1-102 including first and second optical modules 11.1.1-104a-b slidably engaged / coupled to respective guide rods 11.1.1-108a-b and motors 11.1.1-110a-b of left and right adjustment subsystems 11.1.1-106a-b. The IPD adjustment system 11.1.1-102 can include a button 11.1.1-114 coupled to a bracket 11.1.1-112 and in electrical communication with the motors 11.1.1-110a-b. In at least one example, the button 11.1.1-114 is in electrical communication with the first and second motors 11.1.1-110a-b via a processor or other circuit components to activate the first and second motors 11.1.1-110a-b and cause the first and second optical modules 11.1.1-104a-b, respectively, to change position relative to one another.

[0162] In at least one example, the first and second optical modules 11.1.1-104a-b can include respective display screens configured to project light toward the user's eyes when wearing the HMD 11.1.1-100. In at least one example, the user can manipulate (e.g., press and / or rotate) the button 11.1.1-114 to actuate position adjustments 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 can 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.

[0163] In one example, a user can actuate the button 11.1.1-114 to trigger an automatic position adjustment of the first and second optical modules 11.1.1-104a-b. In one example, a user can actuate the button 11.1.1-114 to trigger a manual adjustment, such as moving the optical modules 11.1.1-104a-b farther or closer together when the user rotates the button 11.1.1-114 in one direction or the other, until the user visually aligns their IPD. In one example, the manual adjustment is communicated electronically via one or more circuits, and power for movement of the optical modules 11.1.1-104a-b via the motors 11.1.1-110a-b is provided by a power source. In one example, the adjustment and movement of the optical modules 11.1.1-104a-b via actuation of the button 11.1.1-114 is mechanically actuated via movement of the button 11.1.1-114.

[0164] Any of the features, components, and / or parts shown in Figure 1M, including their arrangement and configuration, alone or in any combination, may be included in any of the other example devices, features, components, and parts shown in any other figure shown and described herein, as well as any of the features, components, and / or parts, including their arrangement and configuration, either alone or in any combination, shown and described with reference to any other figure shown and described herein.

[0165] FIG. 1N shows 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, which define first and second apertures 11.1.2-106a, 11.1.2-106b. The apertures 11.1.2-106a-b are shown with dashed lines in FIG. 1N because the view of the apertures 11.1.2-106a-b may be obstructed 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 can include a first mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104. In at least one example, a mounting bracket 11.1.2-108 is coupled to the inner frame 11.1.2-104 between the first and second apertures 11.1.2-106a-b.

[0166] The mounting bracket 11.1.2-108 may include an intermediate or central portion 11.1.2-109 coupled to the inner frame 11.1.2-104. In some examples, the intermediate or central portion 11.1.2-109 may not be the geometric middle or center of the bracket 11.1.2-108. Rather, the intermediate / central portion 11.1.2-109 may be disposed between first and second cantilevered extension arms extending away from the intermediate portion 11.1.2-109. In at least one example, the mounting bracket 108 includes first and second cantilevered arms 11.1.2-112 and 11.1.2-114 extending away from the intermediate portion 11.1.2-109 of the mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104.

[0167] As shown in FIG. 1N, the outer frame 11.1.2-102 can define a curved shape on its underside to accommodate a user's nose when the user is wearing the HMD 11.1.2-100. The curved shape can be referred to as a nose bridge 11.1.2-111 and can be 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 11.1.2-102 between the apertures 11.1.2-106a-b such that the cantilevered arms 11.1.2-112, 11.1.2-114 extend downward and laterally outward away from the intermediate portion 11.1.2-109 to complement the shape of the nose bridge 11.1.2-111 of the outer frame 11.1.2-104. In this manner, the mounting bracket 11.1.2-108 is configured to accommodate the user's nose as described above. The shape of the nose bridge 11.1.2-111 accommodates the nose in that the nose bridge 11.1.2-111 provides a curvature that curves with, over, on and around the user's nose for comfort and fit.

[0168] The first cantilevered arm 11.1.2-112 can extend in a first direction away from the intermediate portion 11.1.2-109 of the mounting bracket 11.1.2-108, and the second cantilevered arm 11.1.2-114 can extend in a second direction opposite the first direction away from the intermediate portion 11.1.2-109 of the mounting bracket 11.1.2-10. The first and second cantilevered arms 11.1.2-112, 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 distal free end 11.1.2-116, 11.1.2-118, respectively, that is not secured to the inner and outer frames 11.1.2-102, 11.1.2-104. In this way, the arms 11.1.2-112, 11.1.2-114 are cantilevered from intermediate portions 11.1.2-109 which may be connected to the inner frame 11.1.2-104 with the distal ends 11.1.2-102, 11.1.2-104 unattached.

[0169] In at least one example, the HMD 11.1.2-100 can include one or more components coupled to the mounting bracket 11.1.2-108. In one example, the components include a plurality of sensors 11.1.2-110a-f. Each sensor of the plurality of sensors 11.1.2-110a-f can include various types of sensors, including cameras, IR sensors, etc. In some examples, one or more of the sensors 11.1.2-110a-f can be used for object recognition in three-dimensional space, such that maintaining accurate relative positions of two or more of the plurality of sensors 11.1.2-110a-f is important. The cantilevered nature of the mounting bracket 11.1.2-108 can protect the sensors 11.1.2-110a-f from damage and repositioning in the event of an accidental drop by the user. Because the sensors 11.1.2-110a-f are cantilevered onto the arms 11.1.2-112, 11.1.2-114 of the mounting bracket 11.1.2-108, stresses and deformations of the inner and / or outer frames 11.1.2-104, 11.1.2-102 are not transferred to the cantilevered arms 11.1.2-112, 11.1.2-114 and therefore do not affect the relative positioning of the sensors 11.1.2-110a-f coupled / attached to the mounting bracket 11.1.2-108.

[0170] Any of the features, components, and / or parts shown in Figure 1N, including their arrangement and configuration, alone or in any combination, may be included in any of the other example devices, features, and parts described herein. Similarly, any of the features, components, and / or parts shown and described herein, including their arrangement and configuration, alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1N.

[0171] FIG. 10 illustrates an example of an optical module 11.3.2-100 for use in an electronic device, such as an HMD, including the HDM device described herein. As shown in one or more other examples described herein, optical module 11.3.2-100 may be one of two optical modules in an HMD, each aligned to project light toward a user's eye. In this manner, a first optical module can project light toward a first eye of a user through a display screen, and a second optical module of the same device can project light toward a second eye of the user through another display screen.

[0172] In at least one example, the optical module 11.3.2-100 can include an optical frame or housing 11.3.2-102, which can also be referred to as a barrel or optical module barrel. The optical module 11.3.2-100 can also include a display 11.3.2-104, including a display screen or multiple display screens, coupled to the housing 11.3.2-102.

In at least one example, the housing 11.3.2-102 can surround the display 11.3.2-104 and provide a connection mechanism for coupling other components of the optical module described herein.

[0173] 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.

In some embodiments, memory 320, or its non-transitory computer-readable storage medium, stores the following programs, modules, and data structures, or a subset thereof, including an optional operating system 330 and an XR presentation module 340:

[0195] The operating system 330 includes instructions for handling various basic system services and for performing hardware-dependent tasks.

[0201] Furthermore, Figure 3 is intended more to illustrate the functionality of various features that may be present in a particular implementation, as opposed to a structural overview of the embodiments described herein. As will be recognized by those skilled in the art, items shown separately can be combined and some items can be separated. For example, some functional modules shown separately in Figure 3 can be implemented within a single module, and various functions of a single functional block can be implemented by one or more functional blocks in various embodiments. The actual number of modules, as well as the division of specific functionality and how functions are allocated among them, will vary from implementation to implementation and, in some embodiments, will depend in part on the particular combination of hardware, software, and / or firmware selected for a particular implementation.

[0202] 4 is a schematic diagram of an example embodiment of hand tracking device 140. In some embodiments, hand tracking device 140 (FIG. 1A) is controlled by hand tracking unit 244 (FIG. 2) to track the position / location of one or more parts of a user's hand and / or the movement of one or more parts of a user's hand relative to scene 105 of FIG. 1A (e.g., relative to a portion of the physical environment surrounding the user, relative to display generating component 120, or relative to a portion of the user (e.g., the user's face, eyes, or head), and / or relative to the user's hand). In some embodiments, hand tracking device 140 is part of display generating component 120 (e.g., embedded in or attached to a head-mounted device). In some embodiments, hand tracking device 140 is separate from display generating component 120 (e.g., located in a separate housing or attached to a separate physical support structure).

[0203] 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) that captures three-dimensional scene information including at least the hand 406 of a human user. The image sensor 404 captures hand images with sufficient resolution to allow for differentiation of the fingers and their respective positions. The image sensor 404 typically captures images of other parts of the user's body, or all of the body, and can have either zoom capabilities or a dedicated sensor with high magnification to capture hand images 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 or functions as an image sensor that captures the physical environment of the scene 105. In some embodiments, the image sensor 404 is positioned relative to the user or the user's environment such that the field of view of the image sensor, or a portion thereof, is used to define an interaction space in which hand movements captured by the image sensor are processed as inputs to the controller 110.

[0204] In some embodiments, image sensor 404 outputs a sequence of frames containing 3D map data (and possibly color image data) to controller 110, which extracts high-level information from the map data. This high-level information is provided, typically via an application program interface (API), to an application running on the controller, which drives display generation component 120 accordingly. For example, a user can interact with software running on controller 110 by moving their hand 406 and changing the posture of their hand.

[0205] In some embodiments, the image sensor 404 projects a spot pattern onto a scene including 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 shift of the spots of the pattern. This approach is advantageous in that it does not require the user to hold or wear any type of beacon, sensor, or other marker. This provides depth coordinates of points in the scene relative to a predetermined reference plane at a specific distance from the image sensor 404. In this disclosure, the image sensor 404 is assumed to define an orthogonal set of x, y, and z axes such that the depth coordinate of a point in the scene corresponds to the z component measured by the image sensor. Alternatively, the image sensor 404 (e.g., a hand tracking device) can use other 3D mapping methods, such as stereoscopic imaging or time-of-flight measurements, based on single or multiple cameras or other types of sensors.

[0206] In some embodiments, the hand tracking device 140 captures and processes a time sequence of depth maps containing the user's hand while the user moves the hand (e.g., the entire hand or one or more fingers). Software running on the image sensor 404 and / or a processor in the controller 110 processes the 3D map data to extract patch descriptors of the hand in these depth maps. The software matches these descriptors to patch descriptors stored in the database 408, based on a previous training process, to estimate the pose of the hand in each frame. The pose typically includes the 3D locations of the user's wrist joints and fingertips.

[0207] The software can also analyze hand and / or finger trajectories across multiple frames in a sequence to identify gestures. The pose estimation functionality described herein may be interleaved with motion tracking functionality, whereby patch-based pose estimation is performed only once every two (or more) frames, while tracking is used to discover pose changes that occur across the remaining frames. The pose, motion, and gesture information is provided to an application program running on controller 110 via the API described above. This program can, for example, move and modify an image presented on display generation component 120 or perform other functions in response to the pose and / or gesture information.

[0208] In some embodiments, the gesture includes an air gesture, which is detected without (or independent of) 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) and is based on detected movement of a part of the user's body in the air (e.g., head, one or more arms, one or more hands, one or more fingers, and / or one or more legs), 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 of the user's body 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 another of the user's hands, and / or movement of a user's finger relative to another finger or part of the user's hand), and / or absolute movement of the user's body part (e.g., a tap gesture involving movement of a hand in a predetermined posture by a predetermined amount and / or speed, or a shake gesture involving a predetermined speed or amount of rotation of the user's body part).

[0209] In some embodiments, input gestures used in various examples and embodiments described herein include air gestures performed by movement of a user's finger(s) relative to other finger(s) or part(s) of the user's hand to interact with an XR environment (e.g., a virtual or mixed reality environment), according to some embodiments. In some embodiments, an air gesture is a gesture that is 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 is based on detected movement of a part of the user's body in 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 of the user's body 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 the user's other hand relative to one of the user's hands, and / or movement of the user's fingers relative to another finger or part of the user's hand), and / or absolute movement of the user's body part (e.g., a tap gesture that includes movement of the hand in a predetermined pose by a predetermined amount and / or speed, or a shake gesture that includes rotation of the user's body part at a predetermined speed or amount).

[0210] In some embodiments where the input gesture is an air gesture (e.g., in the absence of physical contact with an input device that provides a computer system with information about which user interface element is the target of the user input, such as contact with a user interface element displayed on a touchscreen 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., in the case of direct input, as described below). Thus, in implementations that include air gestures, the input gesture is detected attention (e.g., gaze) to a user interface element in combination with (e.g., simultaneous with) movement of the user's finger(s) and / or hand to perform pinch and / or tap input, as described in more detail below.

[0211] In some embodiments, an input gesture directed at a user interface object is performed directly or indirectly with reference to the user interface object. For example, user input is performed directly at a user interface object in response to performing an input gesture with the user's hand at a position corresponding to the user interface object's position in the three-dimensional environment (e.g., as determined based on the user's current viewpoint). In some embodiments, an input gesture is performed indirectly at a user interface object in response to detecting the user's attention (e.g., gaze) to the user interface object while performing the input gesture while the user's hand position is not at a position corresponding to the user interface object's position in the three-dimensional environment. For example, for a direct input gesture, a user can direct the user's input at a user interface object by initiating the gesture at or near a position corresponding to the user interface object's displayed position (e.g., within a distance of 0.5 cm, 1 cm, 5 cm, or 0-5 cm, measured from an outer edge of the option or a central portion of the option). For indirect input gestures, a user can direct their input to a user interface object by paying attention to the user interface object (e.g., by gazing at the user interface object), and while paying attention to the option, the user initiates an input gesture (e.g., at any position detectable by the computer system) (e.g., at a position that does not correspond to the displayed position of the user interface object).

[0212] In some embodiments, input gestures (e.g., air gestures) used in various examples and embodiments described herein include pinch inputs and tap inputs for interacting with a virtual or mixed reality environment, according to some embodiments. For example, pinch inputs and tap inputs, as described below, are performed as air gestures.

[0213] In some embodiments, the pinch input is part of an air gesture, including 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 that is an air gesture includes moving two or more fingers of a hand to contact each other, i.e., optionally with a short break (e.g., within 0-1 second) after contact with each other. A long pinch gesture that is an air gesture includes moving two or more fingers of a hand to contact each other for at least a threshold amount of time (e.g., at least 1 second) before detecting a break in contact with each other. For example, a long pinch gesture includes a user holding a pinch gesture (e.g., when 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 that is an air gesture includes two (e.g., or more) pinch inputs (e.g., performed by the same hand) that are detected immediately in succession (e.g., within a predetermined period of time) after each other. For example, a user performs a first pinch input (e.g., a pinch input or a long pinch input), releases the first pinch input (e.g., breaking contact between two or more fingers), and performs a second pinch input within a predetermined period of time (e.g., within 1 second or 2 seconds) after releasing the first pinch input.

[0214] 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 (e.g., after) a drag input that changes the position of a user's hand from a first position (e.g., a start position of the drag) to a second position (e.g., an end position of the drag). In some embodiments, a user maintains the pinch gesture while performing the drag input and releases the pinch gesture (e.g., two or more fingers apart) to end the drag gesture (e.g., at the second position). In some embodiments, the pinch input and the drag input are performed with the same hand (e.g., a user pinches two or more fingers together and moves the same hand to the second position in the air with a drag gesture). In some embodiments, the pinch input is performed with a first hand of the user and the drag input is performed with a second hand of the user (e.g., the second hand of the user moves in the air from a first position to a second position while the user continues to perform the pinch input with the first hand). In some embodiments, an input gesture that is an air gesture includes an input (e.g., a pinch input and / or a tap input) performed using both of the user's hands. For example, the input gesture includes two (e.g., or more) pinch inputs performed in conjunction with each other (e.g., simultaneously or within a predetermined period of time). For example, a first pinch gesture (e.g., a pinch input, a long pinch input, or a pinch and drag input) performed using the first hand of the user and a second pinch input performed using the other hand (e.g., the second hand of the user's two hands) in conjunction with performing the pinch input using the first hand. In some embodiments, a movement between the user's hands occurs (e.g., to increase and / or decrease the distance or relative orientation between the user's hands).

[0215] In some embodiments, a tap input (e.g., directed toward a user interface element) performed as an air gesture includes movement(s) of a user's finger(s) toward the user interface element, movement of a user's hand toward a user interface element, optionally with the user's finger(s) extended toward the user interface element, a downward movement of a user's finger (e.g., mimicking a mouse click action or a tap on a touchscreen), 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, moving the finger or hand away from the user's viewpoint and / or toward the object that is the target of the tap input followed by an end of the movement. In some embodiments, an 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 the 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 direction of acceleration of the movement of the finger or hand).

[0216] In some embodiments, the user's attention is determined to be directed to a portion of the three-dimensional environment based on detecting a gaze directed to the portion of the three-dimensional environment (optionally, without requiring other conditions). In some embodiments, the device determines that the user's attention is directed to the portion of the three-dimensional environment based on detecting a gaze directed to the portion of the three-dimensional environment with one or more additional conditions, such as requiring the gaze to be directed to the portion of the three-dimensional environment for at least a threshold duration (e.g., dwell time) while the user's viewpoint is within a distance threshold from the portion of the three-dimensional environment, and / or requiring the gaze to be directed to the portion of the three-dimensional environment, and if one of the additional conditions is not met, the device determines that the user's attention is not directed to the portion of the three-dimensional environment to which the gaze is directed (e.g., until one or more additional conditions are met).

[0217] In some embodiments, detection of a ready configuration of a user or a portion of a user is detected by a computer system, and detection of a ready configuration of the hands is used by the computer system as an indication that the user is likely preparing to interact with the computer system using one or more air gesture inputs performed with the hands (e.g., pinch, tap, pinch and drag, double pinch, 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 geometry (e.g., a pre-pinch geometry with the thumb and one or more fingers extended and spaced apart, ready to perform a pinch or grab gesture, or a pre-tap geometry with one or more fingers extended and the palm facing away from the user), whether the hand is in a predetermined position relative to the user's viewpoint (e.g., below the user's head, above the user's waist, extended at least 15 cm, 20 cm, 25 cm, 30 cm, or 50 cm from the body), and / or whether the hand has moved in a particular manner (e.g., above the user's waist, moved toward an area in front of the user 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 is responsive to attentional (e.g., gaze) input.

[0218] In scenarios where input is described with reference to air gestures, it should be understood that similar gestures can also be detected using a hardware input device attached to or held by one or more of the user's hands, where the position of the hardware input device in space can be tracked using optical tracking, one or more accelerometers, one or more gyroscopes, one or more magnetometers, and / or one or more inertial measurement units, and where the position and / or movement of the hardware input device is substituted for the position and / or movement of the one or more hands in the corresponding air gesture(s). It should be understood that in scenarios where input is described with reference to air gestures, similar gestures can also be detected using a hardware input device attached to or held by one or more of the user's hands. User input can be detected using controls included in a hardware input device, such as one or more touch-sensitive input elements, one or more pressure-sensitive input elements, one or more buttons, one or more knobs, one or more dials, one or more joysticks, one or more hand or finger covers capable of detecting the position or change in position of parts of the hands and / or fingers 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, where user input using controls included in a hardware input device is used in place of a hand and / or finger gesture, such as an air tap or air pinch, in a corresponding air gesture(s). For example, a selection input described as being made with an air tap or air pinch input can alternatively be detected with a button press, a tap on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input.As another example, a movement input described as being made with an air pinch and drag (e.g., an air drag gesture or an air swipe gesture) may alternatively be detected based on an interaction with a hardware input control, such as a press and hold of a button, a touch on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input that follows the movement of a hardware input device in space (e.g., accompanying the hand with which the hardware input device is associated). Similarly, two-handed input, including the movement of both hands relative to each other, may be made using one air gesture and one hardware input device held in the hand not making the air gesture, two hardware input devices held in separate hands, or two air gestures made with separate hands, using various combinations of air gestures and / or input detected by one or more of the hardware input devices described above.

[0219] In some embodiments, the software may be downloaded to the controller 110 in electronic form, for example, over a network, or alternatively may be provided on a tangible, non-transitory medium, such as an optical, magnetic, or electronic memory medium. In some embodiments, the database 408 is similarly stored in memory associated with the controller 110. Alternatively, or additionally, some or all of the described functionality 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). While the controller 110 is shown in FIG. 4 as, by way of example, a separate unit from the image sensor 404, some or all of the processing functionality of the controller may be implemented 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 otherwise 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 set, handheld device, or head-mounted device) or using any other suitable computerized device, such as a game console or media player. The sensing function of the image sensor 404 may likewise be integrated into a computer or other computerized device that is controlled by the sensor output.

[0220] FIG. 4 also includes a schematic diagram of a depth map 410 captured by the image sensor 404, according to some embodiments. The depth map includes a matrix of pixels having respective depth values, as described above. A pixel 412 corresponding to the hand 406 is segmented from the background and wrist in this map. The intensity of each pixel in the depth map 410 is inversely proportional to the depth value, i.e., the measured z-distance from the image sensor 404, with increasing depth resulting in darker shades. The controller 110 processes these depth values ​​to identify and segment components of the image (i.e., groups of adjacent pixels) that have characteristics of a human hand. These characteristics can include, for example, the overall size, shape, and frame-to-frame motion of the depth map sequence.

[0221] 4 also schematically illustrates a hand skeleton 414 that the controller 110 ultimately extracts from the depth map 410 of the hand 406, according to some embodiments. In FIG. 4, the hand skeleton 414 is overlaid on a hand background 416 that was segmented from the original depth map. In some embodiments, key feature points on the hand (e.g., knuckles, fingertips, center of the palm, end of the hand where it connects to the wrist, etc.), and optionally the wrist or arm connected to the hand, are identified and positioned on the hand skeleton 414. In some embodiments, the location and movement of these key feature points over multiple image frames are used by the controller 110 to determine hand gestures performed by the hand or the current state of the hand, according to some embodiments.

[0222] FIG. 5 shows an exemplary embodiment of eye tracking device 130 ( FIG. 1A ). In some embodiments, eye tracking device 130 is controlled by eye tracking unit 243 ( FIG. 2 ) to track the position and movement of a user's gaze relative to scene 105 or relative to XR content displayed via display generation component 120. In some embodiments, eye tracking device 130 is integrated with display generation component 120. For example, in some embodiments, if display generation component 120 is a head-mounted device such as a headset, helmet, goggles, or glasses, or a handheld device disposed in a wearable frame, the head-mounted device includes both components for generating XR content for viewing by the user and components for tracking the user's gaze relative to the XR content. In some embodiments, eye tracking device 130 is separate from display generation component 120. For example, if the display generation component is a handheld device or an XR chamber, eye tracking device 130 is optionally a device separate from the handheld device or the XR chamber. In some embodiments, eye tracking device 130 is a head-mounted device or part of a head-mounted device. In some embodiments, head-mounted eye tracking device 130 is optionally used in conjunction with head-mounted or non-head-mounted display generating components. In some embodiments, eye tracking device 130 is not a head-mounted device, and is optionally used in combination with head-mounted display generating components. In some embodiments, eye tracking device 130 is not a head-mounted device, and is optionally part of non-head-mounted display generating components.

[0223] In some embodiments, the display generation component 120 uses a display mechanism (e.g., left and right near-eye display panels) that displays frames including left and right images in front of the user's eyes to provide the user with a 3D virtual view. For example, the head-mounted display generation component may include left and right optical lenses (referred to herein as eyepieces) positioned between the display and the user's eyes. In some embodiments, the display generation component may include or be coupled to one or more external video 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 that allows the user to view the physical environment directly and display virtual objects on the transparent or translucent display. In some embodiments, the display generation component projects virtual objects into the physical environment. The virtual objects are projected, for example, onto a physical surface or as a hologram, allowing an individual using the system to observe the virtual objects superimposed on the physical environment. In such cases, separate display panels and image frames for the left and right eyes may not be required.

[0224] As shown in FIG. 5 , in some embodiments, eye tracking device 130 (e.g., gaze tracking device) includes at least one eye tracking camera (e.g., an infrared (IR) camera or near-IR (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 may be aimed at the user's eyes to receive reflected IR or NIR light from the light source directly from the eyes, or alternatively, may be aimed at a “hot” mirror positioned between the user's eyes and a display panel that reflects the IR or NIR light from the eyes to the eye tracking camera while allowing visible light to pass through. 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 the images to generate eye tracking information, and communicates the eye tracking information to controller 110. In some embodiments, the user's eyes are tracked separately by their respective eye tracking cameras and illumination sources. In some embodiments, only one eye of the user is tracked by a separate eye-tracking camera and lighting source.

[0225] In some embodiments, the eye tracking device 130 is calibrated using a device-specific calibration process to determine the eye tracking device's parameters for the particular operating environment 100, such as the 3D geometric relationships and parameters of the LEDs, camera, hot mirror (if present), eyepiece, and display screen. The device-specific calibration process may be performed at a factory or another facility before delivery of the AR / VR equipment to the end user. The device-specific calibration process may be an automatic or manual calibration process. The user-specific calibration process may include estimation of a particular user's eye parameters, such as pupil location, central visual location, optical axis, visual axis, eye spacing, etc. According to some embodiments, once the device-specific and user-specific parameters for the eye tracking device 130 have been determined, images captured by the eye tracking camera can be processed using a glint-assisted method to determine the user's current visual axis and point of gaze relative to the display.

[0226] As shown in FIG. 5, eye tracking device 130 (e.g., 130A or 130B) includes an eyepiece(s) 520 and a gaze tracking system including at least one eye tracking camera 540 (e.g., an infrared (IR) or near-IR (NIR) camera) positioned on the side of the user's face where eye tracking occurs 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(s) 592. The eye tracking camera 540 may be positioned between the user's eye(s) 592 and the display 510 (e.g., the left or right display panel of a head-mounted display, or the display of a handheld device, a projector, etc.) and may be directed at a mirror 550 that reflects IR or NIR light from the eye(s) 592 while transmitting visible light (e.g., as shown at the top of FIG. 5), or may be directed at the user's eye(s) 592 to receive reflected IR or NIR light from the eye(s) 592 (e.g., as shown at the bottom of FIG. 5).

[0227] In some embodiments, controller 110 renders AR or VR frames 562 (e.g., left and right frames for left and right display panels) and provides frames 562 to display 510. Controller 110 uses gaze tracking input 542 from eye tracking camera 540 for various purposes, such as in processing frames 562 for display. Controller 110 optionally estimates the user's viewpoint on display 510 based on gaze tracking input 542 obtained from eye tracking camera 540, using a glint-assisted method or other suitable method. The viewpoint estimated from gaze tracking input 542 is optionally used to determine the direction the user is currently looking.

[0228] Some possible use cases of the user's current gaze direction are described below, but are not intended to be limiting. As an exemplary use case, the controller 110 can render virtual content differently based on the determined user's gaze direction. For example, the controller 110 may generate virtual content with higher resolution in a central visual area determined from the user's current gaze direction than in a peripheral area. As another example, the controller may position or move virtual content within a view based at least in part on the user's current gaze direction. As another example, the controller may display particular virtual content within a view based at least in part on the user's current gaze direction. As another exemplary use case in an AR application, the controller 110 can orient an external camera to capture the physical environment of the XR experience and focus in the determined direction. The external camera's autofocus mechanism can then focus on an object or surface within the environment the user is currently viewing on the display 510. As another exemplary use case, eyepiece 520 may be a focusable lens, and eye-tracking information is used by the controller to adjust the focus of eyepiece 520 so that the virtual object the user is currently looking at has the proper binocular coordination to match the convergence of the user's eyes 592. Controller 110 can utilize the eye-tracking information to orient and focus eyepiece 520 so that close objects the user is looking at appear at the correct distance.

[0229] In some embodiments, the eye tracking device is part of a head-mounted device that includes a display (e.g., display 510), two eyepieces (e.g., eyepiece 520), an eye tracking camera (e.g., eye tracking camera(s) 540), and a light source (e.g., illumination source 530 (e.g., IR or NIR LED)) mounted within a wearable housing. The light source emits light (e.g., IR light or NIR light) toward the user's eye(s) 592. In some embodiments, the light sources may be arranged in a ring or circle around each lens, as shown in FIG. 5. In some embodiments, as an example, eight illumination sources 530 (e.g., LEDs) are arranged around each lens 520. However, more or fewer illumination sources 530 may be used, and other arrangements and locations of the illumination sources 530 may be used.

[0230] In some embodiments, the display 510 emits light in the visible light range and not in the IR or NIR range, and therefore does not introduce noise into the gaze tracking system. Note that the location and angle of the eye tracking camera(s) 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.

[0231] Embodiments of an eye tracking system such as that shown in FIG. 5 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.

[0232] FIG. 6 illustrates a glint-assisted gaze tracking pipeline according to some embodiments. In some embodiments, the gaze tracking pipeline is implemented by a glint-assisted gaze tracking system (e.g., eye tracking device 130 as shown in FIGS. 1A and 5). The glint-assisted gaze tracking system can maintain a tracking state. Initially, the tracking state is off or "no." When in the tracking state, the glint-assisted gaze tracking system tracks the pupil contour and glint in the current frame using prior information from the previous frame when analyzing the current frame. When not in the tracking state, the glint-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 to the next frame.

[0233] As shown in FIG. 6, an eye-tracking camera can capture left and right images of a user's left and right eyes. The captured images are then input into an eye-tracking pipeline for processing beginning at 610. As indicated by the arrow returning to element 600, the eye-tracking system can continue to capture images of the user's eyes at a rate of, for example, 60-120 frames per second. In some embodiments, each set of captured images may be input into the pipeline for processing. However, in some embodiments, or under some conditions, not all captured frames are processed by the pipeline.

[0234] At 610, if the tracking status is yes for the currently captured image, the method proceeds to element 640. If the tracking status is no at 610, the image is analyzed to detect the user's pupil and glint in the image, as shown at 620. If the pupil and glint are successfully detected at 630, the method proceeds to element 640. If not, the method returns to element 610 to process the next image of the user's eyes.

[0235] At 640, proceeding from element 610, the current frame is analyzed to track pupils and glints based in part on previous information from the previous frame. At 640, proceeding from element 630, a tracking state is initialized based on the detected pupils and glints in the current frame. The results of the processing at element 640 are checked to ensure that the tracking or detection results are reliable. For example, the results can be checked to determine whether a sufficient number of glints are successfully tracked or detected in the current frame to perform pupil and gaze estimation. At 650, if the results are not reliable, the tracking state is set to no at element 660 and the method returns to element 610 to process the next image of the user's eyes. At 650, if the results are reliable, the method proceeds to element 670. At 670, the tracking state is set to yes (if not already yes) and the pupil and glint information is passed to element 680 to estimate the user's gaze point.

[0236] 6 is intended to serve as an example of eye-tracking technology that may be used in particular implementations. As will be recognized by those skilled in the art, other eye-tracking technologies, now existing or developed in the future, may be used in place of or in combination with the glint-assisted eye-tracking technology described herein in computer system 101 to provide a user with an XR experience according to various embodiments.

[0237] In some embodiments, the captured portion of the real-world environment 602 is used to provide the user with an XR experience, e.g., a mixed reality environment in which one or more virtual objects are overlaid on a representation of the real-world environment 602.

[0238] Accordingly, the description herein describes several embodiments of three-dimensional environments (e.g., XR environments) that include 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 that is captured and displayed within the three-dimensional environment (e.g., actively via a camera and display of the computer system, or passively via a transparent or translucent display of the computer system). As described above, the three-dimensional environment is optionally a mixed reality system based on a physical environment, where the three-dimensional environment is 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 can optionally selectively display portions and / or objects of the physical environment such that each portion and / or object of the physical environment appears to exist within the three-dimensional environment displayed by the computer system. Similarly, the computer system can optionally display virtual objects in the three-dimensional environment such that each portion and / or object of the physical environment appears to exist within the real world (e.g., the physical environment) by placing the virtual objects at respective locations within the three-dimensional environment that have corresponding locations in the real world. For example, the computer system optionally displays the vase so that it appears as if the real vase were placed on a table in the physical environment, hi some embodiments, distinct locations in the three-dimensional environment have corresponding locations in the physical environment.Thus, when a computer system is described as displaying a virtual object at a location distinct from a physical object (e.g., at or near the location of a user's hand, or on or near a physical table, etc.), the computer system displays the virtual object at a particular location in the three-dimensional environment so that the virtual object appears to be at or near the physical object in the physical world (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 the virtual object were a real object at that particular location).

[0239] In some embodiments, real-world objects present in the physical environment (e.g., and / or visible via display generation components) that are displayed in the three-dimensional environment can interact with virtual objects that exist only in the three-dimensional environment. For example, the three-dimensional environment can include a table and a vase placed on the table, where the table is a view (or representation) of the physical table in the physical environment and the vase is a virtual object.

[0240] In a three-dimensional environment (e.g., a real environment, a virtual environment, or an environment containing a mixture of real and virtual objects), objects may be referred to as having depth or simulated depth, or objects may be referred to as being visible, displayed, or located 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., a room or object has a height, depth, and width defined relative to a fixed set of coordinates). In some embodiments, depth is defined relative to a user's location or viewpoint, where the depth dimension varies based on the user's location and / or the location and angle of the user's viewpoint. In some embodiments where depth is defined relative to the location of the user positioned relative to a surface of the environment (e.g., the floor or ground surface of the environment), objects that are farther away from the user along a line extending parallel to the surface are considered to have a greater depth within the environment, and / or the depth of an object is measured along an axis that extends outward from the user's location and is parallel to the surface of the environment (e.g., depth is defined in a cylindrical or substantially cylindrical coordinate system with the user's position at the center of the cylinder extending from the user's head toward the user's feet). Depth is defined relative to the user's viewpoint (e.g., a direction relative to a point in space that determines which parts of the environment are visible through a head-mounted device or other display). In some embodiments, objects that are further away from the user's viewpoint along a line that extends parallel to the direction of the user's viewpoint are considered to have greater depth in the environment, and / or the depth of an object is measured along an axis that extends from the user's viewpoint and extends outward from a line that is parallel to the direction of the user's viewpoint (e.g., depth is defined in a spherical or substantially spherical coordinate system with the origin of the viewpoint 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 application and / or system content is 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, in situations where depth is defined relative to a user interface container, the height and / or width of the container are typically orthogonal or substantially orthogonal to a line extending from a user-based location (e.g., a user's viewpoint or location) to the user interface container (e.g., a center of the user interface container or another feature point of the user interface container) when the container is placed or initially displayed in a three-dimensional environment (e.g., such that the depth dimension of the container extends outward away from the user or the user's viewpoint). In some embodiments, in situations where depth is defined relative to a user interface container, the depth of an object relative to the user interface container refers to the object's position along the depth dimension of the user interface container. In some embodiments, multiple different containers can have different depth dimensions (e.g., different depth dimensions extending in different directions and / or away from different starting points from the user or the user's viewpoint). In some embodiments, when depth is defined for a user interface container, the direction of the depth dimension remains constant for the user interface container when the location 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 a face-to-face 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, in the case of curved containers (e.g., including containers with curved surfaces or curved content regions), the depth dimension optionally extends into the surface of the curved container.In some situations, z separation (e.g., the separation of two objects in the depth dimension), z height (e.g., the distance of one object from another object in the depth dimension), z position (e.g., the position of one object in the depth dimension), z depth (e.g., the position of one object in the depth dimension), or simulated z dimension (e.g., depth used as an object's dimension, an environment's dimension, a direction in space, and / or a direction in a simulated space) are used to refer to the concept of depth as described above.

[0241] In some embodiments, a user can optionally use one or more hands to interact with virtual objects in the three-dimensional environment as if the virtual objects were actual 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 a representation 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, due to the transparency / translucency of the user interface, or the projection of the user interface onto a transparent / translucent surface, or the portion of the display generating components displaying the projection of the user interface to the user's eyes or the field of view of the user's eyes, the user's hands are visible through the display generating components by the ability to see the physical environment through the user interface. Thus, in some embodiments, the user's hands are displayed at discrete locations in the three-dimensional environment and are treated as if they were objects in the three-dimensional environment that can interact with virtual objects in the three-dimensional environment as if they were actual 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.

[0242] In some of the embodiments described below, for example, for purposes of determining whether a physical object is directly interacting with a virtual object (e.g., whether a hand is touching, grabbing, holding, etc., a virtual object, or whether it is within a threshold distance from the virtual object), the computer system can optionally determine an “effective” distance between the physical object in the physical world and the virtual object in the three-dimensional environment. For example, a hand directly interacting with a virtual object optionally includes one or more of the fingers of a hand pressing a virtual button, a user's hand grasping a virtual vase, two fingers of a user's hand pinching / holding an application's user interface together, and any other types of interactions described herein. For example, when determining whether and / or how a user is interacting with a 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 location of the hand in the three-dimensional environment and the location of the target virtual object in the three-dimensional environment. For example, one or more hands of a user are positioned at particular positions in the physical world, which the computer system optionally captures and displays at particular corresponding positions in the three-dimensional environment (e.g., positions in the three-dimensional environment at which the hands are displayed, if the hands are virtual rather than physical hands). The positions of the hands in the three-dimensional environment are optionally compared to positions of target virtual objects in the three-dimensional environment to determine a distance between the user's one or more hands and the virtual objects. In some embodiments, the computer system optionally determines the distance between a physical object and a virtual object by comparing positions in the physical world (e.g., as opposed to comparing positions in the three-dimensional environment).For example, when determining the distance between one or more of a user's hands and a virtual object, the computer system optionally determines the corresponding location in the physical world of the virtual object (e.g., the position where the virtual object would be located in the physical world if the virtual object were a physical object rather than a virtual object), and then determines the distance between the corresponding physical position and the user's one or more hands. In some embodiments, the same technique is optionally used to determine the distance between any physical object and any virtual object. Thus, as described herein, when determining whether a physical object is in contact with a virtual object or whether a physical object is within a threshold distance of a virtual object, the computer system optionally performs any of the above-mentioned techniques to map the location of the physical object to the three-dimensional environment and / or to map the location of the virtual object to the physical environment.

[0243] In some embodiments, the same or similar techniques are used to determine where or what a user's gaze is directed at and / or where or what a physical stylus held by the user is directed at. For example, if a user's gaze is directed at a particular position in the physical environment, the computer system optionally determines a corresponding position in the three-dimensional environment (e.g., a virtual position of the gaze), and if a virtual object is located at that corresponding virtual position, the computer system optionally determines that the user's gaze is directed at that virtual object. Similarly, the computer system can optionally determine where the physical stylus is pointing in the physical environment based on the orientation of the stylus. In some embodiments, based on this determination, the computer system determines a corresponding virtual position in the three-dimensional environment that corresponds to the location in the physical environment where the stylus is pointing, and optionally determines that the stylus is pointing to the corresponding virtual position in the three-dimensional environment.

[0244] Similarly, embodiments described herein may refer to the location of a user (e.g., a user of a computer system) and / or the location of the computer system within a three-dimensional environment. In some embodiments, a user of a computer system is holding, wearing, or otherwise located at or near the computer system. Thus, in some embodiments, the location of the computer system is used as a proxy for the location of the user. In some embodiments, the location of the computer system and / or the user within the physical environment corresponds to a distinct location within the three-dimensional environment. For example, if a user stands at a location facing a distinct portion of the physical environment that is visible through the display generating components, the location of the computer system is the location within the physical environment (and its corresponding location within the three-dimensional environment) at which the user would see objects within the physical environment in the same position, orientation, and / or size (e.g., absolutely and / or relative to each other) as the objects are visible through the display generating components of the computer system within the three-dimensional environment. Similarly, if the virtual objects displayed in the three-dimensional environment were physical objects in the physical environment (e.g., the physical objects were located in the same physical environment location and had the same physical environment size and orientation as in the three-dimensional environment), the location of the computer system and / or user is the position at which the user would see the virtual objects in the physical environment in the same position, orientation, and / or size (e.g., absolutely and / or relative to each other and to real-world objects) as they were displayed by the display generation components of the computer system in the three-dimensional environment.

[0245] In this disclosure, various input methods are described with respect to interaction with a computer system. Where one example is provided using one input device or input method and another example is provided using a different input device or input method, it should be understood that each example may be compatible with, and optionally utilize, 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. Where one example is provided using one output device or output method and another example is provided using a different output device or output method, it should be understood that each example may be compatible with, and optionally utilize, the output device or output method described with respect to the other example. Similarly, various methods are described with respect to interaction with a virtual environment or a mixed reality environment via a computer system. Where one example is provided using interaction with a virtual environment and another example is provided using a mixed reality environment, it should be understood that each example may be compatible with, and optionally utilize, the method described with respect to the other example. Thus, this disclosure discloses embodiments that are combinations of features of multiple examples, without exhaustively listing all features of the embodiments in the description of each exemplary embodiment. User Interface and Related Processes

[0246] Attention is now directed to embodiments of user interfaces ("UI") and associated processes that may be implemented on a computer system, such as a portable multifunction device or head-mounted device, in communication with display generating components and one or more input devices.

[0247] Figures 7A-7Y illustrate exemplary techniques for eye-tracking enrollment, according to some embodiments. Figure 8 is a flow diagram of a method for displaying an enrollment progress user indicator, according to various embodiments. Figure 9 is a flow diagram of a method for animating the movement of a user interface element, according to various embodiments. Figure 10 is a flow diagram of a method for changing the appearance of a user interface element, according to various embodiments. Figure 11 is a flow diagram of a method for moving a user interface element over time, according to various embodiments. The user interfaces of Figures 7A-7Y are used to illustrate the processes described below, including the processes of Figures 8-11.

[0248] 7A illustrates a computer system 700 having a display 702. As shown in FIG. 7A, before initiating a process for registering a 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 computer system's 700's software (e.g., applications and / or operating system). In some embodiments, the computer system 700 may be configured to present virtual objects on one or more transparent or translucent displays (e.g., 702), such that a person using the system perceives virtual objects superimposed on the physical environment. In some embodiments, the computer system 700 is configured to use pass-through video, meaning that one or more cameras or image sensors capture images of the physical environment and use those images in presenting the AR environment on the opaque display.

[0249] 7A-7Y illustrate techniques using a computer system 700 that is a tablet, but these techniques are optionally applicable when using a head-mounted device. In some embodiments in which the computer system 700 is a head-mounted device, the computer system 700 optionally includes two displays (one for each eye of the user of the computer system 700), each display displaying different, separate content to enable the user to perceive different depths of different content. In a head-mounted device, multiple displays are optionally used to present slightly different images to different eyes of the user to create a stereoscopic depth effect. Additionally, for a head-mounted device, different sensors or sets of sensors may be used to track the user's different eyes and more accurately determine the location of the gaze corresponding to the eyes. Accurate gaze tracking is particularly important for head-mounted devices, as gaze is often used to indicate a location in a three-dimensional environment to which attention is directed and, optionally, to determine which element of the three-dimensional environment input is directed (e.g., via hardware input, air gestures, and / or gaze input). For devices that use eye tracking (such as tablets, phones, desktop computers, and head-mounted devices), improved gaze registration leads to improved eye tracking by the device, which makes input more accurate and reduces the need for repeated attempts to perform an action, thereby reducing power usage and (for battery-powered devices) extending battery life.

[0250] In some embodiments, the company indication 704 is displayed as an initial screen after (and / or in response to) booting up 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.

[0251] 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 couch 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 couch 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, couch 712A (and other physical objects from the physical environment) are presented to a user of computer system 700 using pass-through video (e.g., couch 712A is presented by capturing video of the couch via one or more cameras and displaying the video (e.g., in real time) on display 702). In some embodiments in which the three-dimensional environment 712 is part of an augmented reality environment, the couch 712A (and other physical objects from the physical environment) are presented to the user of the computer system 700 using one or more transparent or translucent displays (e.g., the couch 712A is presented to the user by allowing the user to see the couch 712A by looking through the display 702). The three-dimensional environment 712 also includes a representation 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 a cylinder). The target 714 optionally includes a light source that simulates light emitting from the target 714 onto objects (e.g., virtual objects and / or physical objects) in the three-dimensional environment 712.

[0252] While the computer system 700 is displaying the target 714, the computer system 700 detects a gaze 750A of a user of the computer system 700. The gaze indication (e.g., gaze 750A) indicates where the user's gaze is directed and is shown to better understand the present technology. In some embodiments, an indication of the location of the user's gaze is not displayed as part of the user interface of the computer system 700. In some embodiments, an indication of the location of the user's gaze is displayed. In response to detecting gaze 750A and following a determination that gaze 750A has been directed at the target 714 for a threshold amount of time, the computer system 700 initiates animation of the target 714, as described further below. In some embodiments, the threshold amount of time is zero, and any gaze at the target 714 initiates the animation. In some embodiments, the threshold amount of time is non-zero, and a gaze directed at the target 714 must be sustained for the duration of the threshold amount of time to initiate animation.

[0253] In some embodiments, the techniques and user interface(s) described in FIGS. 7A-7Y are provided by one or more of the devices described in FIGS. 1A-1P. FIG. 7B2 illustrates an embodiment in which a target 714 (e.g., as described in FIG. 7B1) is displayed on a display module X702 of a head-mounted device (HMD) X700. In some embodiments, the device X700 includes a pair of display modules that provide stereoscopic content to different eyes of the same user. For example, the HMD X700 includes a display module X702 (providing content to the user's left eye) and a second display module (providing 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.

[0254] 7B2, three-dimensional environment 712 is part of an extended reality environment. In some embodiments, three-dimensional environment 712 is a virtual reality environment, and couch 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 couch 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, couch 712A (and other physical objects from the physical environment) are presented to a user of HMD X700 using pass-through video (e.g., couch 712A is presented by capturing video of the couch via one or more cameras and displaying the video (e.g., in real time) on display X702). In some embodiments in which the three-dimensional environment 712 is part of an augmented reality environment, the couch 712A (and other physical objects from the physical environment) are presented to the user of the HMD X700 using one or more transparent or translucent displays (e.g., the couch 712A is presented to the user by allowing the user to see the couch 712A by looking through the display X702). The three-dimensional environment 712 also includes a representation 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 a cylinder). The target 714 optionally includes a light source that simulates light emitting from the target 714 onto objects (e.g., virtual objects and / or physical objects) in the three-dimensional environment 712.

[0255] While the HMD X700 is displaying the target 714, the HMD X700 detects a gaze X750A of a user of the HMD X700. The gaze indication (e.g., gaze X750A) indicates where the user's gaze is directed and is shown to better understand the technique. In some embodiments, an indication of the location of the user's gaze is not displayed as part of the user interface of the HMD X700. In some embodiments, an indication of the location of the user's gaze is displayed. In response to detecting the gaze X750A and following a determination that the gaze X750A has been directed at the target 714 for a threshold amount of time, the HMD X700 initiates an animation of the target 714, as described further below. In some embodiments, the threshold amount of time is zero, and any gaze at the target 714 initiates the animation. In some embodiments, the threshold amount of time is non-zero, and a gaze directed at the target 714 must be sustained for the duration of the threshold amount of time to initiate the animation.

[0256] 1B-1P, including their arrangements and configurations, alone or in any combination, may be included 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 a display unit 1-102, a display unit 1-202, a display unit 1-306, a display unit 1-406, a display generating component 120, a display screen 1-122a-b, a first and second rear-facing display screen 1-322a, 1-322b, a display 11.3.2-104, a first and second display assemblies 1-120a, 1-120b, a display assembly 1-320, a display assembly 1-421, The invention includes any of the features, components, and / or portions of the first and second display subassemblies 1-420a, 1-420b, display assembly 3-108, display assembly 11.3.2-204, first and second optical modules 11.1.1-104a and 11.1.1-104b, optical module 11.3.2-100, optical module 11.3.2-200, lenticular lens array 3-110, display region or area 6-232, and / or display / display region 6-334, alone or in any combination. In some embodiments, HMD X700 includes a sensor including any of the features, components, and / or portions of any 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 sensors 11.1.2-110a-f, alone or in any combination.In some embodiments, HMD X700 includes one or more input devices including any of the features, components, and / or portions of first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328, alone or in any combination. In some embodiments, HMD X700 optionally includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback (e.g., audio output), generated based on detected events and / or user input detected by HMD X700.

[0257] 7C , the computer system 700 begins animating the target 714, causing the target 714 to shrink as shown in FIG. 7C . After shrinking, the target 714 is replaced with (e.g., expands and / or morphs into) a registration element to begin the gaze registration process (e.g., to calibrate detection of the user's gaze and / or to train the user how to use the user's 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 toward registering the user's gaze, and optionally, the visual appearance of the registration element changes based on the computer system 700 detecting a change in the user's gaze.

[0258] In some embodiments, in addition to (or instead of) detecting the location of the user's gaze, computer system 700 detects pupil dilation information (e.g., the amount of dilation or constriction and / or pupil size) about the user. For example, computer system 700 may gradually (or suddenly) increase and / or decrease the overall brightness of content presented to the user via display 702 to cause the user's pupil dilation and / or constriction. For example, computer system 700 may darken and / or brighten the appearance of the physical environment via display 702 before, during, and / or during the eye-gaze registration process to cause pupil dilation and / or constriction and detect / collect corresponding pupil dilation information. For example, computer system 700 optionally collects pupil dilation information in FIG. 7A when the environment presented to the user is dark, and again collects pupil dilation information throughout the eye-gaze registration process as the brightness (e.g., overall brightness) of the content presented to the user changes (becomes brighter and / or darker).

[0259] In some embodiments, target 714 is viewpoint locked. In some embodiments, target 714 is environment locked. As described, target 714 is replaced with a registration element (e.g., the registration element is displayed in the same location as target 714). In some embodiments, the registration element is environment locked. In some embodiments, target 714 is replaced with registration element 720 including multiple portions 720A-720H, as shown in FIG. 7D. In some embodiments, target 714 is replaced with registration element 730 including multiple portions including portions 730A-730E, as shown in FIG. 7H. In some embodiments, target 714 is replaced with registration element 740 including multiple portions including portions 740A-740E, as shown in FIG. 7L. In some embodiments, target 714 is replaced with registration element 760 including multiple portions including portions 760A-760E, as shown in FIG. 7Q. In some embodiments, target 714 is replaced with registration element 770, as shown in FIG. 7V.

[0260] 7D, registration element 720 is displayed as part of three-dimensional environment 712. Registration element 720 is optionally three-dimensional. Registration element 720 includes a central portion 720I and multiple portions 720A-720H that at least partially surround central portion 720I. When initially displayed, portions 720A-720H have the same appearance (e.g., the same length, the same color, the same size, and / or the same shape).

[0261] In FIG. 7E, as 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 each of the portions 720A-720H based on the location of the user's gaze. FIG. 7E shows two alternative gaze paths 722 (corresponding to gaze 750B) and 724 (corresponding to gaze 750C) within the three-dimensional environment 712. Both gaze paths 722 and 724 are valid paths (with different start / end locations) that allow the computer system 700 to detect gaze information during the gaze registration process. The gaze paths indicate the path the user's gaze takes and are shown to better understand the technique. In some embodiments, the gaze paths are not displayed as part of the user interface of the computer system 700.

[0262] In some embodiments, each of portions 720A-720H increases in length to indicate that computer system 700 has detected the user's gaze at a location corresponding to the respective portion. For example, in FIG. 7E , line of sight 750B begins at the bottom left of registration element 720. Based on the location of line of sight 750B in FIG. 7E , computer system 700 changes the appearance of portion 720A to indicate that the user's gaze has been detected gazing at a location corresponding to portion 720A. In FIG. 7F , as computer system 700 continues to detect line of sight 750B moving along line of sight path 722, computer system 700 sequentially changes the appearance of portions 720B-720D to indicate that the user's gaze has been detected at the locations corresponding to those portions. In Figure 7G, computer system 700 detects that gaze 750B has moved completely (or nearly completely) around central portion 720I of registration element 720 along gaze path 722, and as a result, the appearance of all portions 720A-720H has changed to become longer in length (compared to Figure 7D) to indicate that computer system 700 has detected that the user is gazing at locations corresponding to their respective portions. Because computer system 700 has detected that the user is gazing at locations corresponding to all of portions 720A-720H, this portion of gaze registration is complete, and computer system 700 proceeds to replace registration element 720 with target 714 (e.g., shrink to and / or morph to target 714), as shown in Figure 7Y.

[0263] 7A-7G, including during an eye gaze registration process. In some embodiments, computer system 700 collects gaze information and / or pupil dilation information through the described processes (including with varied brightness) to register a user's gaze so that the user can more accurately target elements (physical and / or virtual elements) within the three-dimensional environment (e.g., three-dimensional environment 712).

[0264] 7H, registration element 730 is displayed as part of three-dimensional environment 712. Registration element 730 is optionally three-dimensional (e.g., a sphere and / or a cylinder). Registration element 730 includes multiple portions (e.g., circles and / or spheres that make up registration element 730) that are grouped into portions 730A-730D in this example. When initially displayed, portions 730A-730D have the same appearance (e.g., the same color and / or the same shape).

[0265] In FIG. 7I, as 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 each of the portions 730A-730D based on the location of the user's gaze. FIG. 7I shows two alternative gaze paths 732 (corresponding to gaze 750D) and 734 (corresponding to gaze 750E) within the three-dimensional environment 712. Both gaze paths 732 and 734 are valid paths (with different start / end locations) that allow the computer system 700 to detect gaze information during the gaze registration process. The gaze paths indicate the path the user's gaze takes and are shown to better understand the technique. In some embodiments, the gaze paths are not displayed as part of the user interface of the computer system 700.

[0266] In some embodiments, each portion of registration element 730 changes appearance to indicate that computer system 700 has detected a user's gaze at a location corresponding to the respective portion. For example, in FIG. 7H , line of sight 750D begins at the bottom right of registration element 730. Based on the location of line of sight 750D in FIG. 7I , computer system 700 changes the appearance of portion 730A to indicate that a user's gaze has been detected at a location corresponding to portion 730A, such as by changing the color of portion 730A to a darker color and / or by changing the amount of light emanating from portion 730A. In FIG. 7J , as computer system 700 continues to detect movement of line of sight 750D along line of sight path 722, computer system 700 changes the appearance of portion 730B to indicate that a user's gaze has been detected at a location corresponding to portion 730B, such as by changing the color of portion 730A to a darker color and / or by changing the amount of light emanating from portion 730B. 7K, computer system 700 detects that gaze 750D has moved completely (or nearly completely) around registration element 730 along gaze path 722, and as a result, updates the appearance of all of portions 730A-730D to further change the color of portions 730C-730D to a darker color and / or change the amount of light emitted from portions 730C-730D, indicating that computer system 700 has detected that the user is gazing at locations corresponding to those respective portions. Because computer system 700 has detected that the user is gazing at locations corresponding to all of portions 730A-730D, this portion of gaze registration is complete, and computer system 700 proceeds to replace registration element 730 with target 714 (e.g., shrink to and / or morph to target 714), as shown in FIG. 7Y.

[0267] 7A-7C and / or 7H-7K, including during the gaze registration process. In some embodiments, computer system 700 collects gaze information and / or pupil dilation information through the described process (including with varying brightness) to register the user's gaze so that the user can more precisely target elements (physical and / or virtual elements) within the three-dimensional environment (e.g., within three-dimensional environment 712).

[0268] Returning to FIG. 7L , registration element 740, including elements 740A-740F, is displayed as part of three-dimensional environment 712. In some embodiments, the elements of registration element 740 (including elements 740A-740F) are spaced apart (e.g., equally spaced or unequally spaced). 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 computer system 700 detects that the gaze of a user of computer system 700 is directed toward a respective location within three-dimensional environment 712, computer system 700 displays indications 780 corresponding to the respective locations within three-dimensional environment 712 of the user's gaze. Indications 780 corresponding to the locations in three-dimensional environment 712 of the user's gaze move as the detected location of the user's gaze moves. In some embodiments, the indication 780 illuminates (e.g., using simulated lighting, such as a simulated spotlight) an area within the three-dimensional environment 712 that corresponds to the location (and / or direction) of the user's gaze.

[0269] In FIG. 7L, the computer system 700 highlights element 740A (742). As shown in FIG. 7L, the other elements of the registered elements 740 (e.g., including 740B-740F) are not highlighted. This prompts the user of the computer system 700 to direct their gaze toward the highlighted element. In FIG. 7L, the computer system 700 detects the user's gaze 750E directed toward element 740A, and in response, the computer system 700 changes the visual appearance of element 740A (e.g., compared to before gaze 750E was directed toward element 740A). In FIG. 7L, the other elements of the registered elements 740 (e.g., including 740B-740F) have a different visual appearance from element 740A because the user's gaze 750E is not directed toward those elements.

[0270] In Figure 7M1, computer system 700 continues to highlight element 740A (742). If computer system 700 determines that the user's gaze 750E remains directed at element 740A (e.g., for less than a threshold amount of time), computer system 700 gradually changes the visual appearance of element 740A, as shown in Figure 7M1. In the example of Figure 7M1, element 740A continues to fade in color as computer system 700 continues to detect the user's gaze 750E remaining directed at element 740A.

[0271] In some embodiments, the techniques and user interface(s) described in FIGS. 7A-7Y are provided by one or more of the devices described in FIGS. 1A-1P. For example, FIG. 7M2 illustrates an embodiment in which highlighting 742 of element 740A (e.g., as described in FIG. 7M1) is displayed on display module X702 of head-mounted device (HMD) X700. In some embodiments, device X700 includes a pair of display modules that provide stereoscopic content to different eyes of the same user. For example, HMD X700 includes display module X702 (providing content to the user's left eye) and a second display module (providing content to the user's right eye). In some embodiments, the second display module displays a slightly different image than display module X702 to create the illusion of stereoscopic depth.

[0272] In Figure 7M2, the HMD X700 continues to highlight element 740A (742). If the HMD X700 determines that the user's gaze X750E remains directed at element 740A (e.g., for less than a threshold amount of time), the HMD X700 gradually changes the visual appearance of element 740A, as shown in Figure 7M2. In the example of Figure 7M2, element 740A continues to fade in color as the HMD X700 continues to detect the user's gaze X750E remaining directed at element 740A.

[0273] 1B-1P, including their arrangements and configurations, alone or in any combination, may be included 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 a display unit 1-102, a display unit 1-202, a display unit 1-306, a display unit 1-406, a display generating component 120, a display screen 1-122a-b, a first and second rear-facing display screen 1-322a, 1-322b, a display 11.3.2-104, a first and second display assemblies 1-120a, 1-120b, a display assembly 1-320, a display assembly 1-421, The invention includes any of the features, components, and / or portions of the first and second display subassemblies 1-420a, 1-420b, display assembly 3-108, display assembly 11.3.2-204, first and second optical modules 11.1.1-104a and 11.1.1-104b, optical module 11.3.2-100, optical module 11.3.2-200, lenticular lens array 3-110, display region or area 6-232, and / or display / display region 6-334, alone or in any combination. In some embodiments, HMD X700 includes a sensor including any of the features, components, and / or portions of any 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 sensors 11.1.2-110a-f, alone or in any combination.In some embodiments, HMD X700 includes one or more input devices including any of the features, components, and / or portions of first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328, alone or in any combination. In some embodiments, HMD X700 optionally includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback (e.g., audio output), generated based on detected events and / or user input detected by HMD X700.

[0274] 7N, computer system 700 determines that a user's gaze 750E has been directed (e.g., continuously) to element 740A for more than a threshold amount of time (e.g., 1 second, 3 seconds, or 5 seconds). In response, computer system 700 updates the appearance of element 740A (e.g., changing its color to white (or another color), changing its shape, and / or changing its size). Further, in response to determining that a user's gaze 750E has been directed (e.g., continuously) to element 740A for more than the threshold amount of time, computer system 700 moves highlight 742 from element 740A to element 740E (e.g., via an animated movement over time), as shown in FIG. 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.

[0275] 7O, computer system 700 detects user's gaze 750E moving past element 740C and, in response, displays indication 780 corresponding to a distinct location within three-dimensional environment 712 of the user's gaze as being partially at the location of element 740C (e.g., partially not at the location of element 740C). In some embodiments, indication 780 illuminates part (or all) of element 740C within three-dimensional environment 712 (e.g., using simulated lighting such as a simulated spotlight) without illuminating other elements of registered element 740. In FIG. 7O, in response to user's gaze 750E no longer being directed at element 740A, computer system 700 begins to change (and / or revert) the appearance of element 740A (e.g., change color back to dark, change shape, and / or change size).

[0276] In Figure 7P, computer system 700 continues to change (and / or restore) the appearance of element 740A based on the user's gaze 750E not being directed at element 740A. As a result, in Figure 7P, the visual appearance of element 740A is the same as it was before user's gaze 750E was directed at element 740A (Figure 7L). In Figure 7P, computer system 700 has detected user's gaze 750E being directed at element 740E for more than a threshold amount of time and has accordingly changed the visual appearance of element 740E (e.g., changed color to white (or another color), changed shape, and / or changed size). In some embodiments, computer system 700 gradually changes the appearance of element 740E over time while detecting that user's gaze 750E is directed at element 740E, thereby providing visual feedback to the user that the user's gaze is directed at the individual element. 7P further illustrates that, in response to computer system 700 detecting that user's gaze 750E has been directed at element 740E for more than a threshold amount of time, computer system 700 moves highlight 742 from element 740E to element 740F (e.g., via an animated movement over time). Moving highlight 742 to element 740F is intended to encourage and / or prompt a user of computer system 700 to move their gaze to element 740F, thereby enabling computer system 700 to capture additional gaze information regarding the user's gaze.

[0277] In some embodiments, when computer system 700 detects that the user's gaze 750E is no longer directed at element 740E, computer system 700 begins to modify (and / or restore) the appearance of element 740E (e.g., change the color back to a darker color, change the shape, and / or change the size). In some embodiments, when computer system detects that the user's gaze is directed at an individual element that is not highlighted, computer system 700 forgoes gradually modifying the appearance of the individual element over time (e.g., only changing the appearance based on indication 780 that illuminates the individual element in three-dimensional environment 712 (e.g., using simulated lighting such as a simulated spotlight)).

[0278] In some embodiments, when the computer system 700 detects that the user is gazing at a distinct number of highlighted elements (e.g., four locations, six locations, or eight locations) for a threshold amount of time, this portion of the gaze registration is complete, and the computer system 700 proceeds to replace (e.g., shrink and / or morph into) the registered element 740 with the target 714, as illustrated in FIG. 7Y.

[0279] 7A-7C and / or 7L-7P, including during the gaze registration process. In some embodiments, computer system 700 collects gaze information and / or pupil dilation information through the described process (including with varying brightness) to register the user's gaze so that the user can more accurately target elements (physical and / or virtual elements) within the three-dimensional environment (e.g., within three-dimensional environment 712).

[0280] Returning to FIG. 7Q, target 714 (of FIG. 7C) has been decomposed to form registration element 760, which includes elements 760A-760F positioned as part of three-dimensional environment 712. In some embodiments, the elements of registration element 760 (including elements 740A-740H) are spaced apart (e.g., equally spaced or unequal spaced) in three axes in three-dimensional space. In some embodiments, the elements of registration element 760 (including elements 740A-740H) are arranged in a three-dimensional arrangement (e.g., a three-dimensional array or a three-dimensional grid). In some embodiments, the elements of registration element 760 (including elements 740A-740H) are randomly or pseudo-randomly distributed within the three-dimensional area of ​​three-dimensional environment 712. In some embodiments, the elements of registration element 760 (including elements 740A-740H) have different colors. In some embodiments, the elements of registration element 760 (including elements 740A-740H) are different sizes.

[0281] When the computer system 700 detects that the gaze of the user of the computer system 700 is directed toward a respective direction and / or a respective location within the three-dimensional environment 712, the computer system 700 animates elements of the registration elements 760 corresponding to those respective directions and / or locations to move to (and / or converge at) a specific location within the three-dimensional environment 712. FIG. 7R shows two alternative gaze paths 762 (corresponding to gaze 750F) and 764 (corresponding to gaze 750G) within the three-dimensional environment 712. Both gaze paths 762 and 764 are valid paths (with different start / end locations and different directions) that enable the computer system 700 to detect gaze information during the gaze registration process. The gaze paths indicate the path the user's gaze takes and are shown to better understand the technique. In some embodiments, the gaze paths are not displayed as part of the user interface of the computer system 700.

[0282] 7R, computer system 700 detects that a line of sight 750F of a user of computer system 700 is directed toward a location within three-dimensional environment 712. In response to detecting line of sight 750F directed toward the location, the computer system animates elements of registered elements 760 that are at locations corresponding to line of sight 750F (e.g., within a threshold distance of line of sight 750F and / or at the location of line of sight 750F), including elements 760A and 760B, to move from their respective locations to a central location. In FIG. 7R, the elements (including elements 760A and 760B) that have moved to the central location visually combine to form element 760I. In some embodiments, the color of element 760I is optionally based on the color (and optionally the size) of the elements that have moved to the central location and visually combined to form element 760I. In some embodiments, the size of element 760I is optionally based on the amount (and optionally the size) of the elements that have moved to the central location and visually combined to form element 760I. In Figure 7R, the color of element 760I is based on the element that has been moved to the center location and is no longer clearly indicated (as was previously the case in Figure 7Q). In Figure 7R, the size of element 760I is based on the number of elements that have been moved to the center location and is no longer clearly indicated (as was previously the case in Figure 7Q).

[0283] In FIG. 7S1, computer system 700 detects movement of line of sight 750F of a user of computer system 700 along path 762 to a new location within three-dimensional environment 712. In response to detecting movement of line of sight 750F to the new location, the computer system animates elements of registered elements 760 that are located at locations (e.g., within a threshold distance of line of sight 750F and / or at the location of line of sight 750F) corresponding to the new location of line of sight 750F (and corresponding to intermediate locations during movement), including elements 760C and 760D, to move from their respective locations to a central location. In FIG. 7S1, the elements (including elements 760A-760D) that have moved to the central location are visually combined to form element 760I. In some embodiments, the color of element 760I is optionally based on the color (and optionally the size) of the elements that moved to the central location and visually combined to form element 760I. In some embodiments, the size of element 760I is optionally based on the amount (and optionally the size) of elements that have moved to the central location and visually combined to form element 760I. In Figure 7S1, the color of element 760I has changed compared to Figure 7R because additional elements have moved to the central location and are no longer clearly displayed. In Figure 7S1, the size of element 760I has increased based on the increased number of elements that have moved to the central location and are no longer clearly displayed.

[0284] In some embodiments, the techniques and user interface(s) described in FIGS. 7A-7Y are provided by one or more of the devices described in FIGS. 1A-1P. For example, FIG. 7S2 shows an embodiment in which a registration element 760 (e.g., as described in FIGS. 7Q-7S1) is displayed on a display module X702 of a head-mounted device (HMD) X700. In some embodiments, the device X700 includes a pair of display modules that provide stereoscopic content to different eyes of the same user. For example, the HMD X700 includes a display module X702 (providing content to the user's left eye) and a second display module (providing 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.

[0285] In FIG. 7S2, the HMD X700 detects movement along a path 762 of the line of sight X750F of the user of the HMD X700 to a new location within the three-dimensional environment 712. In response to detecting movement of the line of sight X750F to the new location, the HMD X700 animates elements of the registered elements 760 that are at locations (e.g., within a threshold distance of and / or at the location of the line of sight X750F) corresponding to the new location of the line of sight X750F (and corresponding to intermediate locations during movement), including elements 760C and 760D, to move from their respective locations to a central location. In FIG. 7S2, the elements (including elements 760A-760D) that moved to the central location visually combine to form element 760I. In some embodiments, the color of element 760I is optionally based on the color (and optionally the size) of the elements that moved to the central location and visually combined to form element 760I. In some embodiments, the size of element 760I is optionally based on the amount (and optionally the size) of elements that have moved to the central location and visually combined to form element 760I. In Figure 7S2, the color of element 760I has changed compared to Figure 7R because additional elements have moved to the central location and are no longer clearly displayed. In Figure 7S2, the size of element 760I has increased based on the increased number of elements that have moved to the central location and are no longer clearly displayed.

In some embodiments, HMD X700 optionally includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback (e.g., audio output), generated based on detected events and / or user input detected by HMD X700.

[0287] In FIG. 7T, computer system 700 detects further movement of line of sight 750F of the user of computer system 700 to a third location within three-dimensional environment 712. In response to detecting movement of line of sight 750F to the third location, the computer system animates elements of registered elements 760 that are located at locations (e.g., within a threshold distance of line of sight 750F and / or at locations of line of sight 760F) corresponding to the third location of line of sight 750F (and corresponding to intermediate locations during movement), including elements 760E and 760F, to move from their respective locations to a central location. In FIG. 7T, the elements (including elements 760A-760F) that moved to the central location visually combine to form element 760I.
