DEVICES, METHODS, AND GRAPHICAL USER INTERFACES FOR DEVICE POSITION ADJUSTMENT

The present disclosure generally relates to methods and graphical user interfaces for providing feedback pertaining to device position adjustment.

TECHNICAL FIELD

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

BACKGROUND

The development of computer systems for augmented reality has increased significantly in recent years. Example 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 touch-screen displays for computer systems and other electronic computing devices are used to interact with virtual/augmented reality environments. Example virtual elements include virtual objects, such as digital images, video, text, icons, and control elements such as buttons and other graphics.

SUMMARY

Some methods and interfaces for adjusting device positioning are cumbersome, inefficient, and limited. For example, systems that provide insufficient, unclear, or confusing feedback for accurate device positioning are complex, tedious, and error-prone, create a significant cognitive burden on a user, and detract from the experience with the virtual/augmented reality environment. In addition, these methods take longer than necessary, thereby wasting energy of the computer system. This latter consideration is particularly important in battery-operated devices.

Accordingly, there is a need for computer systems with improved methods and interfaces for providing feedback pertaining to device position adjustment that make interaction with the computer systems more efficient and intuitive for a user. Such methods and interfaces optionally complement or replace conventional methods for providing feedback pertaining to device position adjustment. Such methods and interfaces reduce the number, extent, and/or nature of the inputs from a user by helping the user to understand the connection between provided inputs and device responses to the inputs, thereby creating a more efficient human-machine interface.

The above deficiencies and other problems associated with user interfaces for computer systems are reduced or eliminated by the disclosed systems. In some embodiments, the computer system is a desktop computer with an associated display. In some embodiments, the computer system is portable device (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the computer system is a personal electronic device (e.g., a wearable electronic device, such as a watch, or 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 “touch-screen display”). In some embodiments, the computer system has one or more eye-tracking components. In some embodiments, the computer system has one or more hand-tracking components. In some embodiments, the computer system has one or more output devices in addition to the display generation component, 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 sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI through a stylus and/or finger contacts and gestures on the touch-sensitive surface, movement of the user's eyes and hand 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 inputs 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, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, note taking, and/or digital video playing. Executable instructions for performing these functions are, optionally, included in a transitory and/or non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors.

There is a need for electronic devices with improved methods and interfaces for providing feedback pertaining to device position adjustment. Such methods and interfaces may complement or replace conventional methods for providing feedback pertaining to device position adjustment. Such methods and interfaces reduce the number, extent, and/or the nature of the inputs from a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges.

DESCRIPTION OF EMBODIMENTS

The present disclosure relates to user interfaces for providing an extended reality (XR) experience to a user, in some embodiments.

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

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

In some embodiments, a computer system detects a position of a portion of the computer system relative to a portion of a body of a user. In some embodiments, proper positioning of the computer system relative to the face of the user assists in providing the user with an improved experience, for example, by allowing the user to view displayed content properly and/or allowing the user to provide more accurate user inputs (e.g., eye-based and/or gaze-based inputs). Accordingly, in some embodiments, when the computer system detects that the position of the portion of the computer system relative to the face of the user meets one or more error conditions (e.g., the portion of the computer system is too far to the left, too far to the right, too high, and/or too low relative to the face of the user; and/or the computer system is too close to or too far from the face of the user), the computer system displays a notification. In some embodiments, certain types of errors are considered more important or more serious than others. Accordingly, when the error condition is a first type of error condition that is considered a more serious error, the computer system displays a first alert; and when the error condition is a second type of error condition that is considered less serious, the computer system displays a second alert different from the first alert.

The user interfaces inFIGS.7A-7Hare used to illustrate the processes inFIG.8.FIGS.9A-9Gillustrate example techniques for providing feedback pertaining to device position adjustment, in some embodiments.FIG.10is a flow diagram of methods or providing feedback pertaining to device position adjustment, in some embodiments. The user interfaces inFIGS.9A-9Gare used to illustrate the processes inFIG.10.

The processes described below enhance the operability of the devices and make the user-device interfaces more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) through various techniques, including by providing improved visual feedback to the user, reducing the number of inputs needed to perform an operation, providing additional control options without cluttering the user interface with additional displayed controls, performing an operation when a set of conditions has been met without requiring further user input, improving privacy and/or security, providing a more varied, detailed, and/or realistic user experience while saving storage space, and/or additional techniques. These techniques also reduce power usage and improve battery life of the device by enabling the user to use the device more quickly and efficiently. Saving on battery power, and thus weight, improves the ergonomics of the device. These techniques also enable real-time communication, allow for the use of fewer and/or less precise sensors resulting in a more compact, lighter, and cheaper device, and enable the device to be used in a variety of lighting conditions. These techniques reduce energy usage, thereby reducing heat emitted by the device, which is particularly important for a wearable device where a device well within operational parameters for device components can become uncomfortable for a user to wear if it is producing too much heat.

In some embodiments, as shown inFIG.1A, the XR experience is provided to the user via an operating environment100that includes a computer system101. The computer system101includes a controller110(e.g., processors of a portable electronic device or a remote server), a display generation component120(e.g., a head-mounted device (IMD), a display, a projector, a touch-screen, etc.), one or more input devices125(e.g., an eye tracking device130, a hand tracking device140, other input devices150), one or more output devices155(e.g., speakers160, tactile output generators170, and other output devices180), one or more sensors190(e.g., image sensors, light sensors, depth sensors, tactile sensors, orientation sensors, proximity sensors, temperature sensors, location sensors, motion sensors, velocity sensors, etc.), and optionally one or more peripheral devices195(e.g., home appliances, wearable devices, etc.). In some embodiments, one or more of the input devices125, output devices155, sensors190, and peripheral devices195are integrated with the display generation component120(e.g., in a head-mounted device or a handheld device).

When describing a XR experience, various terms are used to differentially refer to several related but distinct environments that the user may sense and/or with which a user may interact (e.g., with inputs detected by a computer system101generating the XR experience that cause the computer system generating the XR experience to generate audio, visual, and/or tactile feedback corresponding to various inputs provided to the computer system101). The following is a subset of these terms:

Extended reality: In contrast, an extended reality (XR) environment refers to a wholly or partially simulated environment that people sense and/or interact with via an electronic system. In XR, a subset of a person's physical motions, or representations thereof, are tracked, and, in response, one or more characteristics of one or more virtual objects simulated in the XR environment are adjusted in a manner that comports with at least one law of physics. For example, a XR system may detect a person's head turning and, in response, adjust graphical content and an acoustic field presented to the person in a manner similar to how such views and sounds would change in a physical environment. In some situations (e.g., for accessibility reasons), adjustments to characteristic(s) of virtual object(s) in a XR environment may be made in response to representations of physical motions (e.g., vocal commands). A person may sense and/or interact with a 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 point audio sources in 3D space. In another example, audio objects may enable audio transparency, which 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 only with audio objects.

Examples of XR include virtual reality and mixed reality.

Mixed reality: In contrast to a VR environment, which is designed to be based entirely on computer-generated sensory inputs, a mixed reality (MR) environment refers to a simulated environment that is designed to incorporate sensory inputs from the physical environment, or a representation thereof, in addition to including computer-generated sensory inputs (e.g., virtual objects). On a virtuality continuum, a mixed reality environment is anywhere between, but not including, a wholly physical environment at one end and virtual reality environment at the other end. In some MR environments, computer-generated sensory inputs may respond to changes in sensory inputs from the physical environment. Also, some electronic systems for presenting an MR environment may track location and/or orientation with respect to the physical environment to enable virtual objects to interact with real objects (that is, physical articles from the physical environment or representations thereof). For example, a system may account for movements so that a virtual tree appears stationary with respect to the physical ground.

Augmented reality: An augmented reality (AR) environment refers to a simulated environment in which one or more virtual objects are superimposed over 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 may directly view the physical environment. The system may be configured to present virtual objects on the transparent or translucent display, so that a person, using the system, perceives the virtual objects superimposed over the physical environment. Alternatively, a system may have an opaque display and one or more imaging sensors that capture images or video of the physical environment, which are representations of the physical environment. The system composites the images or video with virtual objects, and presents the composition on the opaque display. A person, using the system, indirectly views the physical environment by way of the images or video of the physical environment, and perceives the virtual objects superimposed over the physical environment. As used herein, a video of the physical environment shown on an opaque display is called “pass-through video,” meaning a system uses one or more image sensor(s) to capture images of the physical environment, and uses those images in presenting the AR environment on the opaque display. Further alternatively, a system may have a projection system that projects virtual objects into the physical environment, for example, as a hologram or on a physical surface, so that a person, using the system, perceives the virtual objects superimposed over the physical environment. An augmented reality environment also refers to a simulated environment in which a representation of a physical environment is transformed by computer-generated sensory information. For example, in providing pass-through video, a system may transform one or more sensor images to impose a select perspective (e.g., viewpoint) different than the perspective captured by the imaging sensors. As another example, a representation of a physical environment may be transformed by graphically modifying (e.g., enlarging) portions thereof, such that the modified portion may be representative but not photorealistic versions of the originally captured images. As a further example, a representation of a physical environment may be transformed by graphically eliminating or obfuscating portions thereof.

In an augmented reality, mixed reality, or virtual reality environment, a view of a three-dimensional environment is visible to a user. The view of the three-dimensional environment is typically visible to the user via one or more display generation components (e.g., a display or a pair of display modules that provide stereoscopic content to different eyes of the same user) through a virtual viewport that has a viewport boundary that defines an extent of the three-dimensional environment that is visible to the user via the one or more display generation components. In some embodiments, the region defined by the viewport boundary is smaller than a range of vision of the user in one or more dimensions (e.g., based on the range of vision of the user, size, optical properties or other physical characteristics of the one or more display generation components, and/or the location and/or orientation of the one or more display generation components relative to the eyes of the user). In some embodiments, the region defined by the viewport boundary is larger than a range of vision of the user in one or more dimensions (e.g., based on the range of vision of the user, size, optical properties or other physical characteristics of the one or more display generation components, and/or the location and/or orientation of the one or more display generation components relative to the eyes of the user). The viewport and viewport boundary typically move as the one or more display generation components move (e.g., moving with a head of the user for a head mounted device or moving with a hand of a user for a handheld device such as a tablet or smartphone). A viewpoint of a user determines what content is visible in the viewport, a viewpoint generally specifies a location and a direction relative to the three-dimensional environment, and as the viewpoint shifts, the view of the three-dimensional environment will also shift in the viewport. For a head mounted device, a viewpoint is typically based on a location an direction of the head, face, and/or eyes of a user to provide a view of the three-dimensional environment that is perceptually accurate and provides an immersive experience when the user is using the head-mounted device. For a handheld or stationed device, the viewpoint shifts as the handheld or stationed device is moved and/or as a position of a user relative to the handheld or stationed device changes (e.g., a user moving toward, away from, up, down, to the right, and/or to the left of the device). For devices that include display generation components with virtual passthrough, portions of the physical environment that are visible (e.g., displayed, and/or projected) via the one or more display generation components are based on a field of view of one or more cameras in communication with the display generation components which typically move with the display generation components (e.g., moving with a head of the user for a head mounted device or moving with a hand of a user for a handheld device such as a tablet or smartphone) because the viewpoint of the user moves as the field of view of the one or more cameras moves (and the appearance of one or more virtual objects displayed via the one or more display generation components is updated based on the viewpoint of the user (e.g., displayed positions and poses of the virtual objects are updated based on the movement of the viewpoint of the user)). For display generation components with optical passthrough, portions of the physical environment that are visible (e.g., optically visible through one or more partially or fully transparent portions of the display generation component) via the one or more display generation components are based on a field of view of a user through the partially or fully transparent portion(s) of the display generation component (e.g., moving with a head of the user for a head mounted device or moving with a hand of a user for a handheld device such as a tablet or smartphone) because the viewpoint of the user moves as the field of view of the user through the partially or fully transparent portions of the display generation components moves (and the appearance of one or more virtual objects is updated based on the viewpoint of the user).

In some embodiments a representation of a physical environment (e.g., displayed via virtual passthrough or optical passthrough) can be partially or fully obscured by a virtual environment. In some embodiments, the amount of virtual environment that is displayed (e.g., the amount of physical environment that is not displayed) is based on an immersion level for the virtual environment (e.g., with respect 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 reducing the immersion level optionally causes less of the virtual environment to be displayed, revealing portions of the physical environment that were previously not displayed and/or obscured. In some embodiments, at a particular immersion level, one or more first background objects (e.g., in the representation of the physical environment) are visually de-emphasized (e.g., dimmed, blurred, and/or displayed with increased transparency) more than one or more second background objects, and one or more third background objects cease to be displayed. In some embodiments, a level of immersion includes an associated degree to which the virtual content displayed by the computer system (e.g., the virtual environment and/or the virtual content) obscures background content (e.g., content other than the virtual environment and/or the virtual content) around/behind the virtual content, optionally including the number of items of background content displayed and/or the visual characteristics (e.g., colors, contrast, and/or opacity) with which the background content is displayed, the angular range of the virtual content displayed via the display generation component (e.g., 60 degrees of content displayed at low immersion, 120 degrees of content displayed at medium immersion, or 180 degrees of content displayed at high immersion), and/or the proportion of the field of view displayed via the display generation component 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 a background over which the virtual content is displayed (e.g., background content in the representation of the physical environment). In some embodiments, the background content includes user interfaces (e.g., user interfaces generated by the computer system corresponding to applications), virtual objects (e.g., files or representations of other users generated by the computer system) not associated with or included in the virtual environment and/or virtual content, and/or real objects (e.g., pass-through objects representing real objects in the physical environment around the user that are visible such that they are displayed via the display generation component and/or a visible via a transparent or translucent component of the display generation component because the computer system does not obscure/prevent visibility of them through the display generation component). In some embodiments, at a low level of immersion (e.g., a first level of immersion), the background, virtual and/or real objects are displayed in an unobscured manner. For example, a virtual environment with a low level of immersion is optionally displayed concurrently with the background content, which is optionally displayed with full brightness, color, and/or translucency. In some embodiments, at a higher level of immersion (e.g., a second level of immersion higher than the first level of immersion), the background, virtual and/or real objects are displayed in an obscured manner (e.g., dimmed, blurred, or removed from display). For example, a respective virtual environment with a high level of immersion is displayed without concurrently displaying the background content (e.g., in a full screen or fully immersive mode). As another example, a virtual environment displayed with a medium level of immersion is displayed concurrently with darkened, blurred, or otherwise de-emphasized background content. In some embodiments, the visual characteristics of the background objects vary among the background objects. For example, at a particular immersion level, one or more first background objects are visually de-emphasized (e.g., dimmed, blurred, and/or displayed with increased transparency) more than one or more second background objects, and one or more third background objects cease to be displayed. In some embodiments, a null or zero level of immersion corresponds to the virtual environment ceasing to be displayed and instead a representation of a physical environment is displayed (optionally with one or more virtual objects such as application, windows, or virtual three-dimensional objects) without the representation of the physical environment being obscured by the virtual environment. Adjusting the level of immersion using a physical input element provides for quick and efficient method of adjusting immersion, which enhances the operability of the computer system and makes the user-device interface more efficient.

Viewpoint-locked virtual object: A virtual object is viewpoint-locked when a computer system displays the virtual object at the same location and/or position in the viewpoint of the user, even as the viewpoint of the user shifts (e.g., changes). In embodiments where the computer system is a head-mounted device, the viewpoint of the user is locked to the forward facing direction of the user's head (e.g., the viewpoint of the user is at least a portion of the field-of-view of the user when the user is looking straight ahead); thus, the viewpoint of the user remains fixed even as the user's gaze is shifted, without moving the user's head. In embodiments where the computer system has a display generation component (e.g., a display screen) that can be repositioned with respect to the user's head, the viewpoint of the user is the augmented reality view that is being presented to the user on a display generation component of the computer system. For example, a viewpoint-locked virtual object that is displayed in the upper left corner of the viewpoint of the user, when the viewpoint of the user is in a first orientation (e.g., with the user's head facing north) continues to be displayed in the upper left corner of the viewpoint of the user, even as the viewpoint of the user changes to a second orientation (e.g., with the user's head facing west). In other words, the location and/or position at which the viewpoint-locked virtual object is displayed in the viewpoint of the user 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 viewpoint of the user 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.”

Environment-locked virtual object: A virtual object is environment-locked (alternatively, “world-locked”) when a computer system displays the virtual object at a location and/or position in the viewpoint of the user that is based on (e.g., selected in reference to and/or anchored to) a location and/or object in the three-dimensional environment (e.g., a physical environment or a virtual environment). As the viewpoint of the user shifts, the location and/or object in the environment relative to the viewpoint of the user changes, which results in the environment-locked virtual object being displayed at a different location and/or position in the viewpoint of the user. For example, an environment-locked virtual object that is locked onto a tree that is immediately in front of a user is displayed at the center of the viewpoint of the user. When the viewpoint of the user shifts to the right (e.g., the user's head is turned to the right) so that the tree is now left-of-center in the viewpoint of the user (e.g., the tree's position in the viewpoint of the user shifts), the environment-locked virtual object that is locked onto the tree is displayed left-of-center in the viewpoint of the user. In other words, the location and/or position at which the environment-locked virtual object is displayed in the viewpoint of the user is dependent on the position and/or orientation of the location and/or object in the environment onto which the virtual object is locked. In some embodiments, the computer system uses a stationary frame of reference (e.g., a coordinate system that is anchored to a fixed location and/or object in the physical environment) in order to determine the position at which to display an environment-locked virtual object in the viewpoint of the user. An environment-locked virtual object can be locked to a stationary part of the environment (e.g., a floor, wall, table, or other stationary object) or can be locked to a moveable part of the environment (e.g., a vehicle, animal, person, or even a representation of portion of the users body that moves independently of a viewpoint of the user, such as a user's hand, wrist, arm, or foot) so that the virtual object is moved as the viewpoint or the portion of the environment moves to maintain a fixed relationship between the virtual object and the portion of the environment.

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

In some embodiments, spatial media includes spatial visual media and/or spatial audio. In some embodiments, a spatial capture is a capture of spatial media. In some embodiments, spatial visual media (also referred to as stereoscopic media) (e.g., a spatial image and/or a spatial video) is media that includes two different images or sets of images, representing two perspectives of the same or overlapping fields-of-view, for concurrent display. A first image representing a first perspective is presented to a first eye of the viewer and a second image representing a second perspective, different from the first perspective, is concurrently presented to a second eye of the viewer. The first image and the second image have the same or overlapping fields-of-view. In some embodiments, a computer system displays the first image via a first display that is positioned for viewing by the first eye of the viewer and concurrently displays the second image via a second display, different from the first display, that is position for viewing by the second eye of the viewer. In some embodiments, the first image and the second image, when viewed together, create a depth effect and provide the viewer with depth perception for the contents of the images. In some embodiments, a first video representing a first perspective is presented to a first eye of the viewer and a second video representing a second perspective, different from the first perspective, is concurrently presented to a second eye of the viewer. The first video and the second video have the same or overlapping fields-of-view. In some embodiments, the first video and the second video, when viewed together, create a depth effect and provide the viewer with depth perception for the contents of the videos. In some embodiments, spatial audio experiences in headphones are produced by manipulating sounds in the headphone's two audio channels (e.g., left and right) so that they resemble directional sounds arriving in the ear-canal. For example, the headphones can reproduce a spatial audio signal that simulates a soundscape around the listener (also referred to as the user). An effective spatial sound reproduction can render sounds such that the listener perceives the sound as coming from a location within the soundscape external to the listener's head, just as the listener would experience the sound if encountered in the real world.

The geometry of the listener's ear, and in particular the outer ear (pinna), has a significant effect on the sound that arrives from a sound source to a listener's eardrum. The spatial audio sound experience is possible by taking into account the effect of the listener's pinna, the listener's head, and/or the listener's torso to the sound that enters to the listener's ear-canal. The geometry of the user's ear is optionally determined by using a three-dimensional scanning device that produces a three-dimensional model of at least a portion of the visible parts of the user's ear. This geometry is optionally used to produce a filter for producing the spatial audio experience. In some embodiments, spatial audio is audio that has been filtered such that a listener of the audio perceives the audio as coming from one or more directions and/or locations in three-dimensional space (e.g., from above, below, and/or in front of the listener).

An example of such a filter is a Head-Related Transfer Function (HRTF) filter. These filters are used to provide an effect that is similar to how a human ear, head, and torso filter sounds. When the geometry of the ears of a listener is known, a personalized filter (e.g., a personalized HRTF filter) can be produced 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, two filters are produced-one filter per ear-so that each ear of the listener has a corresponding personalized filter (e.g., personalized HRTF filter), as the ears of the listener may be of different geometry.

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

Hardware: There are many different types of electronic systems that enable a person to sense and/or interact with various XR environments. Examples include head-mounted systems, projection-based systems, heads-up displays (HUDs), vehicle windshields having integrated display capability, windows having integrated display capability, displays formed as lenses designed to be placed on a person's eyes (e.g., similar to 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 for providing 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). The head-mounted system may incorporate one or more imaging sensors to capture images or video of the physical environment, and/or one or more microphones to capture audio of the physical environment. Rather than an opaque display, a head-mounted system may have a transparent or translucent display. The transparent or translucent display may have a medium through which light representative of images is directed to a person's eyes. The display may utilize digital light projection, OLEDs, LEDs, uLEDs, liquid crystal on silicon, laser scanning light source, or any combination of these technologies. The medium may be an optical waveguide, a hologram medium, an optical combiner, an optical reflector, or any combination thereof. In one embodiment, the transparent or translucent display may be configured to become opaque selectively. Projection-based systems may employ retinal projection technology that projects graphical images onto a person's retina. Projection systems also may be configured to project virtual objects into the physical environment, for example, as a hologram or on a physical surface. In some embodiments, the controller110is configured to manage and coordinate a XR experience for the user. In some embodiments, the controller110includes a suitable combination of software, firmware, and/or hardware. The controller110is described in greater detail below with respect toFIG.2. In some embodiments, the controller110is a computing device that is local or remote relative to the scene105(e.g., a physical environment). For example, the controller110is a local server located within the scene105. In another example, the controller110is a remote server located outside of the scene105(e.g., a cloud server, central server, etc.). In some embodiments, the controller110is communicatively coupled with the display generation component120(e.g., an HMD, a display, a projector, a touch-screen, etc.) via one or more wired or wireless communication channels144(e.g., BLUETOOTH, IEEE 802.11x, IEEE 802.16x, IEEE 802.3x, etc.). In another example, the controller110is included within the enclosure (e.g., a physical housing) of the display generation component120(e.g., an HMD, or a portable electronic device that includes a display and one or more processors, etc.), one or more of the input devices125, one or more of the output devices155, one or more of the sensors190, and/or one or more of the peripheral devices195, or share the same physical enclosure or support structure with one or more of the above.

In some embodiments, the display generation component120is configured to provide the XR experience (e.g., at least a visual component of the XR experience) to the user. In some embodiments, the display generation component120includes a suitable combination of software, firmware, and/or hardware. The display generation component120is described in greater detail below with respect toFIG.3. In some embodiments, the functionalities of the controller110are provided by and/or combined with the display generation component120.

According to some embodiments, the display generation component120provides a XR experience to the user while the user is virtually and/or physically present within the scene105.

In some embodiments, the display generation component is worn on a part of the user's body (e.g., on his/her head, on his/her hand, etc.). As such, the display generation component120includes one or more XR displays provided to display the XR content. For example, in various embodiments, the display generation component120encloses the field-of-view of the user. In some embodiments, the display generation component120is a handheld device (such as a smartphone or tablet) configured to present XR content, and the user holds the device with a display directed towards the field-of-view of the user and a camera directed towards the scene105. In some embodiments, the handheld device is optionally placed within an enclosure that is worn on the head of the user. In some embodiments, the handheld device is optionally placed on a support (e.g., a tripod) in front of the user. In some embodiments, the display generation component120is a XR chamber, enclosure, or room configured to present XR content in which the user does not wear or hold the display generation component120. 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) could 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 showing interactions with XR content triggered based on interactions that happen in a space in front of a handheld or tripod mounted device could similarly be implemented with an HMD where the interactions happen in a space in front of the HMD and the responses of the XR content are displayed via the HMD. Similarly, a user interface showing interactions with XR content triggered based on movement of a handheld or tripod mounted device relative to the physical environment (e.g., the scene105or a part of the user's body (e.g., the user's eye(s), head, or hand)) could similarly be implemented with an HMD where the movement is caused by movement of the HMD relative to the physical environment (e.g., the scene105or a part of the user's body (e.g., the user's eye(s), head, or hand)).

While pertinent features of the operating environment100are shown inFIG.1A, those of ordinary skill in the art will appreciate from the present disclosure that various other features have not been illustrated for the sake of brevity and so as not to obscure more pertinent aspects of the example embodiments disclosed herein.

FIGS.1A-1Pillustrate various examples of a computer system that is used to perform the methods and provide audio, visual and/or haptic feedback as part of user interfaces described herein. In some embodiments, the computer system includes one or more display generation components (e.g., first and second display assemblies1-120a,1-120band/or first and second optical modules11.1.1-104aand11.1.1-104b) for displaying virtual elements and/or a representation of a physical environment to a user of the computer system, optionally generated based on detected events and/or user inputs detected by the computer system. User interfaces generated by the computer system are optionally corrected by one or more corrective lenses11.3.2-216that are optionally removably attached to one or more of the optical modules to enable the user interfaces to be more easily viewed by users who would otherwise use glasses or contacts to correct their vision. While many user interfaces illustrated herein show a single view of a user interface, user interfaces in a HMD are optionally displayed using two optical modules (e.g., first and second display assemblies1-120a,1-120band/or first and second optical modules11.1.1-104aand11.1.1-104b), one for a user's right eye and a different one for a user's left eye, and slightly different images are presented to the two different eyes to generate the illusion of stereoscopic depth, the single view of the user interface would typically be either a right-eye or left-eye view and the depth effect is explained in the text or using other schematic charts or views. In some embodiments, the computer system includes one or more external displays (e.g., display assembly1-108) for displaying status information for the computer system to the user of the computer system (when the computer system is not being worn) and/or to other people who are near the computer system, optionally generated based on detected events and/or user inputs detected by the computer system. In some embodiments, the computer system includes one or more audio output components (e.g., electronic component1-112) for generating audio feedback, optionally generated based on detected events and/or user inputs detected by the computer system. In some embodiments, the computer system includes one or more input devices for detecting input such as one or more sensors (e.g., one or more sensors in sensor assembly1-356, and/orFIG.1I) for detecting information about a physical environment of the device which can be used (optionally in conjunction with one or more illuminators such as the illuminators described inFIG.1I) to generate a digital passthrough image, capture visual media corresponding to the physical environment (e.g., photos and/or video), or determine a pose (e.g., position and/or orientation) of physical objects and/or surfaces in the physical environment so that virtual objects ban be placed based on a detected pose of 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., one or more sensors in sensor assembly1-356, and/orFIG.1I) that can be used (optionally in conjunction with one or more illuminators such as the illuminators6-124described inFIG.1I) to determine when one or more air gestures have been 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., eye tracking and gaze tracking sensors inFIG.1I) which can be used (optionally in conjunction with one or more lights such as lights11.3.2-110inFIG.10) to determine attention or gaze position and/or gaze movement which can optionally be used to detect gaze-only inputs based on gaze movement and/or dwell. A combination of the various sensors described above can be used to determine user facial expressions and/or hand movements for use in generating an avatar or representation of the user such as an anthropomorphic avatar or representation for use in a real-time communication session where the avatar has facial expressions, hand movements, and/or body movements that are based on or similar to detected facial expressions, hand movements, and/or body movements of a 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 that use one or more hardware input devices such as one or more buttons (e.g., first button1-128, button11.1.1-114, second button1-132, and or dial or button1-328), knobs (e.g., first button1-128, button11.1.1-114, and/or dial or button1-328), digital crowns (e.g., first button1-128which is depressible and twistable or rotatable, button11.1.1-114, and/or dial or button1-328), trackpads, touch screens, keyboards, mice and/or other input devices. One or more buttons (e.g., first button1-128, button11.1.1-114, second button1-132, and or dial or button1-328) are optionally used to perform system operations such as recentering content in three-dimensional environment that is visible to a user of the device, displaying a home user interface for launching applications, starting real-time communication sessions, or initiating display of virtual three-dimensional backgrounds. Knobs or digital crowns (e.g., first button1-128which is depressible and twistable or rotatable, button11.1.1-114, and/or dial or button1-328) are optionally rotatable to adjust parameters of the visual content such as a level of immersion of a virtual three-dimensional environment (e.g., a degree to which virtual-content occupies the viewport of the user into the three-dimensional environment) or other parameters associated with the three-dimensional environment and the virtual content that is displayed via the optical modules (e.g., first and second display assemblies1-120a,1-120band/or first and second optical modules11.1.1-104aand11.1.1-104b).

FIG.1Billustrates a front, top, perspective view of an example of a head-mountable display (HMD) device1-100configured to be donned by a user and provide virtual and altered/mixed reality (VR/AR) experiences. The HMD1-100can include a display unit1-102or assembly, an electronic strap assembly1-104connected to and extending from the display unit1-102, and a band assembly1-106secured at either end to the electronic strap assembly1-104. The electronic strap assembly1-104and the band1-106can be part of a retention assembly configured to wrap around a user's head to hold the display unit1-102against the face of the user.

In at least one example, the band assembly1-106can include a first band1-116configured to wrap around the rear side of a user's head and a second band1-117configured to extend over the top of a user's head. The second strap can extend between first and second electronic straps1-105a,1-105bof the electronic strap assembly1-104as shown. The strap assembly1-104and the band assembly1-106can be part of a securement mechanism extending rearward from the display unit1-102and configured to hold the display unit1-102against a face of a user.

In at least one example, the securement mechanism includes a first electronic strap1-105aincluding a first proximal end1-134coupled to the display unit1-102, for example a housing1-150of the display unit1-102, and a first distal end1-136opposite the first proximal end1-134. The securement mechanism can also include a second electronic strap1-105bincluding a second proximal end1-138coupled to the housing1-150of the display unit1-102and a second distal end1-140opposite the second proximal end1-138. The securement mechanism can also include the first band1-116including a first end1-142coupled to the first distal end1-136and a second end1-144coupled to the second distal end1-140and the second band1-117extending between the first electronic strap1-105aand the second electronic strap1-105b. The straps1-105a-band band1-116can be coupled via connection mechanisms or assemblies1-114. In at least one example, the second band1-117includes a first end1-146coupled to the first electronic strap1-105abetween the first proximal end1-134and the first distal end1-136and a second end1-148coupled to the second electronic strap1-105bbetween the second proximal end1-138and the second distal end1-140.

In at least one example, the first and second electronic straps1-105a-binclude plastic, metal, or other structural materials forming the shape the substantially rigid straps1-105a-b. In at least one example, the first and second bands1-116,1-117are formed of elastic, flexible materials including woven textiles, rubbers, and the like. The first and second bands1-116,1-117can be flexible to conform to the shape of the user' head when donning the HMD1-100.

In at least one example, one or more of the first and second electronic straps1-105a-bcan define internal strap volumes and include one or more electronic components disposed in the internal strap volumes. In one example, as shown inFIG.1B, the first electronic strap1-105acan include an electronic component1-112. In one example, the electronic component1-112can include a speaker. In one example, the electronic component1-112can include a computing component such as a processor.

In at least one example, the housing1-150defines a first, front-facing opening1-152. The front-facing opening is labeled in dotted lines at1-152inFIG.1Bbecause the display assembly1-108is disposed to occlude the first opening1-152from view when the HMD1-100is assembled. The housing1-150can also define a rear-facing second opening1-154. The housing1-150also defines an internal volume between the first and second openings1-152,1-154. In at least one example, the HMD1-100includes the display assembly1-108, which can include a front cover and display screen (shown in other figures) disposed in or across the front opening1-152to occlude the front opening1-152. In at least one example, the display screen of the display assembly1-108, as well as the display assembly1-108in general, has a curvature configured to follow the curvature of a user's face. The display screen of the display assembly1-108can be curved as shown to compliment the user's facial features and general curvature from one side of the face to the other, for example from left to right and/or from top to bottom where the display unit1-102is pressed.

In at least one example, the housing1-150can define a first aperture1-126between the first and second openings1-152,1-154and a second aperture1-130between the first and second openings1-152,1-154. The HMD1-100can also include a first button1-128disposed in the first aperture1-126and a second button1-132disposed in the second aperture1-130. The first and second buttons1-128,1-132can be depressible through the respective apertures1-126,1-130. In at least one example, the first button1-126and/or second button1-132can be twistable dials as well as depressible buttons. In at least one example, the first button1-128is a depressible and twistable dial button and the second button1-132is a depressible button.

FIG.1Cillustrates a rear, perspective view of the HMD1-100.

The apertures11.1.2-106a-bare shown in dotted lines inFIG.1Nbecause a view of the apertures11.1.2-106a-bcan be blocked by one or more other components of the HMD11.1.2-100coupled to the inner frame11.1.2-104and/or the outer frame11.1.2-102, as shown. In at least one example, the HMD11.1.2-100can include a first mounting bracket11.1.2-108coupled to the inner frame11.1.2-104. In at least one example, the mounting bracket11.1.2-108is coupled to the inner frame11.1.2-104between the first and second apertures11.1.2-106a-b.

The mounting bracket11.1.2-108can include a middle or central portion11.1.2-109coupled to the inner frame11.1.2-104. In some examples, the middle or central portion11.1.2-109may not be the geometric middle or center of the bracket11.1.2-108. Rather, the middle/central portion11.1.2-109can be disposed between first and second cantilevered extension arms extending away from the middle portion11.1.2-109. In at least one example, the mounting bracket108includes a first cantilever arm11.1.2-112and a second cantilever arm11.1.2-114extending away from the middle portion11.1.2-109of the mount bracket11.1.2-108coupled to the inner frame11.1.2-104.

As shown inFIG.1N, the outer frame11.1.2-102can define a curved geometry on a lower side thereof to accommodate a user's nose when the user dons the HMD11.1.2-100. The curved geometry can be referred to as a nose bridge11.1.2-111and be centrally located on a lower side of the HMD11.1.2-100as shown. In at least one example, the mounting bracket11.1.2-108can be connected to the inner frame11.1.2-104between the apertures11.1.2-106a-bsuch that the cantilevered arms11.1.2-112,11.1.2-114extend downward and laterally outward away from the middle portion11.1.2-109to compliment the nose bridge11.1.2-111geometry of the outer frame11.1.2-102. In this way, the mounting bracket11.1.2-108is configured to accommodate the user's nose as noted above. The nose bridge11.1.2-111geometry accommodates the nose in that the nose bridge11.1.2-111provides a curvature that curves with, above, over, and around the user's nose for comfort and fit.

The first cantilever arm11.1.2-112can extend away from the middle portion11.1.2-109of the mounting bracket11.1.2-108in a first direction and the second cantilever arm11.1.2-114can extend away from the middle portion11.1.2-109of the mounting bracket11.1.2-10in a second direction opposite the first direction. The first and second cantilever arms11.1.2-112,11.1.2-114are referred to as “cantilevered” or “cantilever” arms because each arm11.1.2-112,11.1.2-114, includes a distal free end11.1.2-116,11.1.2-118, respectively, which are free of affixation from the inner and outer frames11.1.2-102,11.1.2-104. In this way, the arms11.1.2-112,11.1.2-114are cantilevered from the middle portion11.1.2-109, which can be connected to the inner frame11.1.2-104, with distal ends11.1.2-102,11.1.2-104unattached.

In at least one example, the HMD11.1.2-100can include one or more components coupled to the mounting bracket11.1.2-108. In one example, the components include a plurality of sensors11.1.2-110a-f. Each sensor of the plurality of sensors11.1.2-110a-fcan include various types of sensors, including cameras, IR sensors, and so forth. In some examples, one or more of the sensors11.1.2-110a-fcan be used for object recognition in three-dimensional space such that it is important to maintain a precise relative position of two or more of the plurality of sensors11.1.2-110a-f. The cantilevered nature of the mounting bracket11.1.2-108can protect the sensors11.1.2-110a-ffrom damage and altered positioning in the case of accidental drops by the user. Because the sensors11.1.2-110a-fare cantilevered on the arms11.1.2-112,11.1.2-114of the mounting bracket11.1.2-108, stresses and deformations of the inner and/or outer frames11.1.2-104,11.1.2-102are not transferred to the cantilevered arms11.1.2-112,11.1.2-114and thus do not affect the relative positioning of the sensors11.1.2-110a-fcoupled/mounted to the mounting bracket11.1.2-108.

FIG.4is a schematic, pictorial illustration of an example embodiment of the hand tracking device140. In some embodiments, hand tracking device140(FIG.1A) is controlled by hand tracking unit244(FIG.2) to track the position/location of one or more portions of the user's hands, and/or motions of one or more portions of the user's hands with respect to the scene105ofFIG.1A(e.g., with respect to a portion of the physical environment surrounding the user, with respect to the display generation component120, or with respect to a portion of the user (e.g., the user's face, eyes, or head), and/or relative to a coordinate system defined relative to the user's hand). In some embodiments, the hand tracking device140is part of the display generation component120(e.g., embedded in or attached to a head-mounted device). In some embodiments, the hand tracking device140is separate from the display generation component120(e.g., located in separate housings or attached to separate physical support structures).

In some embodiments, the hand tracking device140includes image sensors404(e.g., one or more IR cameras, 3D cameras, depth cameras, and/or color cameras, etc.) that capture three-dimensional scene information that includes at least a hand406of a human user. The image sensors404capture the hand images with sufficient resolution to enable the fingers and their respective positions to be distinguished. The image sensors404typically capture images of other parts of the user's body, as well, or possibly all of the body, and may have either zoom capabilities or a dedicated sensor with enhanced magnification to capture images of the hand with the desired resolution. In some embodiments, the image sensors404also capture 2D color video images of the hand406and other elements of the scene. In some embodiments, the image sensors404are used in conjunction with other image sensors to capture the physical environment of the scene105, or serve as the image sensors that capture the physical environments of the scene105. In some embodiments, the image sensors404are positioned relative to the user or the user's environment in a way that a field of view of the image sensors or a portion thereof is used to define an interaction space in which hand movement captured by the image sensors are treated as inputs to the controller110.

In some embodiments, the image sensors404output a sequence of frames containing 3D map data (and possibly color image data, as well) to the controller110, which extracts high-level information from the map data. This high-level information is typically provided via an Application Program Interface (API) to an application running on the controller, which drives the display generation component120accordingly. For example, the user may interact with software running on the controller110by moving his hand406and changing his hand posture.

In some embodiments, the image sensors404project a pattern of spots onto a scene containing the hand406and capture an image of the projected pattern. In some embodiments, the controller110computes the 3D coordinates of points in the scene (including points on the surface of the user's hand) by triangulation, based on transverse shifts of the spots in the pattern. This approach is advantageous in that it does not require the user to hold or wear any sort of beacon, sensor, or other marker. It gives the depth coordinates of points in the scene relative to a predetermined reference plane, at a certain distance from the image sensors404. In the present disclosure, the image sensors404are assumed to define an orthogonal set of x, y, z axes, so that depth coordinates of points in the scene correspond to z components measured by the image sensors. Alternatively, the image sensors404(e.g., a hand tracking device) may use other methods of 3D mapping, such as stereoscopic imaging or time-of-flight measurements, based on single or multiple cameras or other types of sensors.

In some embodiments, the hand tracking device140captures and processes a temporal sequence of depth maps containing the user's hand, while the user moves his hand (e.g., whole hand or one or more fingers). Software running on a processor in the image sensors404and/or the controller110processes 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 a database408, based on a prior learning process, in order to estimate the pose of the hand in each frame. The pose typically includes 3D locations of the user's hand joints and finger tips.

The software may also analyze the trajectory of the hands and/or fingers over multiple frames in the sequence in order to identify gestures. The pose estimation functions described herein may be interleaved with motion tracking functions, so that patch-based pose estimation is performed only once in every two (or more) frames, while tracking is used to find changes in the pose that occur over the remaining frames. The pose, motion, and gesture information are provided via the above-mentioned API to an application program running on the controller110. This program may, for example, move and modify images presented on the display generation component120, or perform other functions, in response to the pose and/or gesture information.

In some embodiments, a gesture includes an air gesture. An air gesture is a gesture that is detected without the user touching (or independently of) an input element that is part of a device (e.g., computer system101, one or more input device125, and/or hand tracking device140) and is based on detected motion of a portion (e.g., the head, one or more arms, one or more hands, one or more fingers, and/or one or more legs) of the user's body through the air including motion of the user's body relative to an absolute reference (e.g., an angle of the user's arm relative to the ground or a distance of the user's hand relative to the ground), relative to another portion of the user's body (e.g., movement of a hand of the user relative to a shoulder of the user, movement of one hand of the user relative to another hand of the user, and/or movement of a finger of the user relative to another finger or portion of a hand of the user), and/or absolute motion of a portion of the user's body (e.g., a tap gesture that includes movement of a hand in a predetermined pose by a predetermined amount and/or speed, or a shake gesture that includes a predetermined speed or amount of rotation of a portion of the user's body).

In some embodiments, input gestures used in the various examples and embodiments described herein include air gestures performed by movement of the user's finger(s) relative to other finger(s) (or part(s) of the user's hand) for interacting with an XR environment (e.g., a virtual or mixed-reality environment), in 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 independently of an input element that is a part of the device) and is based on detected motion of a portion of the user's body through the air including motion of the user's body relative to an absolute reference (e.g., an angle of the user's arm relative to the ground or a distance of the user's hand relative to the ground), relative to another portion of the user's body (e.g., movement of a hand of the user relative to a shoulder of the user, movement of one hand of the user relative to another hand of the user, and/or movement of a finger of the user relative to another finger or portion of a hand of the user), and/or absolute motion of a portion of the user's body (e.g., a tap gesture that includes movement of a hand in a predetermined pose by a predetermined amount and/or speed, or a shake gesture that includes a predetermined speed or amount of rotation of a portion of the user's body).

In some embodiments in which the input gesture is an air gesture (e.g., in the absence of physical contact with an input device that provides the 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 the user interface element), the gesture takes into account the user's attention (e.g., gaze) to determine the target of the user input (e.g., for direct inputs, as described below). Thus, in implementations involving air gestures, the input gesture is, for example, detected attention (e.g., gaze) toward the user interface element in combination (e.g., concurrent) with movement of a user's finger(s) and/or hands to perform a pinch and/or tap input, as described in more detail below.

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

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

In some embodiments, a pinch input is part of an air gesture that includes one or more of: a pinch gesture, a long pinch gesture, a pinch and drag gesture, or a double pinch gesture. For example, a pinch gesture that is an air gesture includes movement of two or more fingers of a hand to make contact with one another, that is, optionally, followed by an immediate (e.g., within 0-1 seconds) break in contact from each other. A long pinch gesture that is an air gesture includes movement of two or more fingers of a hand to make contact with one another for at least a threshold amount of time (e.g., at least 1 second), before detecting a break in contact with one another. For example, a long pinch gesture includes the user holding a pinch gesture (e.g., with the two or more fingers making 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 comprises two (e.g., or more) pinch inputs (e.g., performed by the same hand) detected in immediate (e.g., within a predefined time period) succession of each other. For example, the user performs a first pinch input (e.g., a pinch input or a long pinch input), releases the first pinch input (e.g., breaks contact between the two or more fingers), and performs a second pinch input within a predefined time period (e.g., within 1 second or within 2 seconds) after releasing the first pinch input.

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

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

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

In some embodiments, the detection of a ready state configuration of a user or a portion of a user is detected by the computer system. Detection of a ready state configuration of a hand is used by a 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 by the hand (e.g., a pinch, tap, pinch and drag, double pinch, long pinch, or other air gesture described herein). For example, the ready state of the hand is determined based on whether the hand has a predetermined hand shape (e.g., a pre-pinch shape with a thumb and one or more fingers extended and spaced apart ready to make a pinch or grab gesture or a pre-tap with one or more fingers extended and palm facing away from the user), based on whether the hand is in a predetermined position relative to a viewpoint of the user (e.g., below the user's head and above the user's waist and extended out from the body by at least 15, 20, 25, 30, or 50 cm), and/or based on whether the hand has moved in a particular manner (e.g., moved toward a region in front of the user above the user's waist and below the user's head or moved away from the user's body or leg). In some embodiments, the ready state is used to determine whether interactive elements of the user interface respond to attention (e.g., gaze) inputs.

In scenarios where inputs are described with reference to air gestures, it should be understood that similar gestures could be detected using a hardware input device that is attached to or held by one or more hands of a user, 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 the position and/or movement of the hardware input device is used in place of the position and/or movement of the one or more hands in the corresponding air gesture(s). In scenarios where inputs are described with reference to air gestures, it should be understood that similar gestures could be detected using a hardware input device that is attached to or held by one or more hands of a user, user inputs can be detected with controls contained in the hardware input device such as one or more touch-sensitive input elements, one or more pressure-sensitive input elements, one or more buttons, one or more knobs, one or more dials, one or more joysticks, one or more hand or finger coverings that can detect a position or change in position of portions of a hand and/or fingers relative to each other, relative to the user's body, and/or relative to a physical environment of the user, and/or other hardware input device controls, wherein the user inputs with the controls contained in the hardware input device are used in place of hand and/or finger gestures such as air taps or air pinches in the corresponding air gesture(s). For example, a selection input that is described as being performed with an air tap or air pinch input could be alternatively 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 that is described as being performed with an air pinch and drag could be alternatively detected based on an interaction with the hardware input control such as a button press and hold, a touch on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input that is followed by movement of the hardware input device (e.g., along with the hand with which the hardware input device is associated) through space. Similarly, a two-handed input that includes movement of the hands relative to each other could be performed with one air gesture and one hardware input device in the hand that is not performing the air gesture, two hardware input devices held in different hands, or two air gestures performed by different hands using various combinations of air gestures and/or the inputs detected by one or more hardware input devices that are described above.

In some embodiments, the software may be downloaded to the controller110in electronic form, over a network, for example, or it may alternatively be provided on tangible, non-transitory media, such as optical, magnetic, or electronic memory media. In some embodiments, the database408is likewise stored in a memory associated with the controller110. Alternatively or additionally, some or all of the described functions of the computer may be implemented in dedicated hardware, such as a custom or semi-custom integrated circuit or a programmable digital signal processor (DSP). Although the controller110is shown inFIG.4, by way of example, as a separate unit from the image sensors404, some or all of the processing functions of the controller may be performed by a suitable microprocessor and software or by dedicated circuitry within the housing of the image sensors404(e.g., a hand tracking device) or otherwise associated with the image sensors404. In some embodiments, at least some of these processing functions may be carried out by a suitable processor that is integrated with the display generation component120(e.g., in a television set, a handheld device, or head-mounted device, for example) or with any other suitable computerized device, such as a game console or media player. The sensing functions of image sensors404may likewise be integrated into the computer or other computerized apparatus that is to be controlled by the sensor output.

FIG.4further includes a schematic representation of a depth map410captured by the image sensors404, in some embodiments. The depth map, as explained above, comprises a matrix of pixels having respective depth values. The pixels412corresponding to the hand406have been segmented out from the background and the wrist in this map. The brightness of each pixel within the depth map410corresponds inversely to its depth value, i.e., the measured z distance from the image sensors404, with the shade of gray growing darker with increasing depth. The controller110processes these depth values in order to identify and segment a component of the image (i.e., a group of neighboring pixels) having characteristics of a human hand. These characteristics, may include, for example, overall size, shape and motion from frame to frame of the sequence of depth maps.

FIG.4also schematically illustrates a hand skeleton414that controller110ultimately extracts from the depth map410of the hand406, in some embodiments. InFIG.4, the hand skeleton414is superimposed on a hand background416that has been segmented from the original depth map. In some embodiments, key feature points of the hand (e.g., points corresponding to knuckles, finger tips, center of the palm, end of the hand connecting to wrist, etc.) and optionally on the wrist or arm connected to the hand are identified and located on the hand skeleton414. In some embodiments, location and movements of these key feature points over multiple image frames are used by the controller110to determine the hand gestures performed by the hand or the current state of the hand, in some embodiments.

FIG.5illustrates an example embodiment of the eye tracking device130(FIG.1A). In some embodiments, the eye tracking device130is controlled by the eye tracking unit243(FIG.2) to track the position and movement of the user's gaze with respect to the scene105or with respect to the XR content displayed via the display generation component120. In some embodiments, the eye tracking device130is integrated with the display generation component120. For example, in some embodiments, when the display generation component120is a head-mounted device such as headset, helmet, goggles, or glasses, or a handheld device placed in a wearable frame, the head-mounted device includes both a component that generates the XR content for viewing by the user and a component for tracking the gaze of the user relative to the XR content. In some embodiments, the eye tracking device130is separate from the display generation component120. For example, when display generation component is a handheld device or a XR chamber, the eye tracking device130is optionally a separate device from the handheld device or XR chamber. In some embodiments, the eye tracking device130is a head-mounted device or part of a head-mounted device. In some embodiments, the head-mounted eye-tracking device130is optionally used in conjunction with a display generation component that is also head-mounted, or a display generation component that is not head-mounted. In some embodiments, the eye tracking device130is not a head-mounted device, and is optionally used in conjunction with a head-mounted display generation component. In some embodiments, the eye tracking device130is not a head-mounted device, and is optionally part of a non-head-mounted display generation component.

In some embodiments, the display generation component120uses a display mechanism (e.g., left and right near-eye display panels) for displaying frames including left and right images in front of a user's eyes to thus provide 3D virtual views to the user. For example, a head-mounted display generation component may include left and right optical lenses (referred to herein as eye lenses) located between the display and the user's eyes. In some embodiments, the display generation component may include or be coupled to one or more external video cameras that capture video of the user's environment for display. In some embodiments, a head-mounted display generation component may have a transparent or semi-transparent display through which a user may view the physical environment directly and display virtual objects on the transparent or semi-transparent display. In some embodiments, display generation component projects virtual objects into the physical environment. The virtual objects may be projected, for example, on a physical surface or as a holograph, so that an individual, using the system, observes the virtual objects superimposed over the physical environment. In such cases, separate display panels and image frames for the left and right eyes may not be necessary.

As shown inFIG.5, in some embodiments, eye tracking device130(e.g., a gaze tracking device) includes at least one eye tracking camera (e.g., infrared (IR) or near-IR (NIR) cameras), and illumination sources (e.g., IR or NIR light sources such as an array or ring of LEDs) that emit light (e.g., IR or NIR light) towards the user's eyes. The eye tracking cameras may be pointed towards the user's eyes to receive reflected IR or NR light from the light sources directly from the eyes, or alternatively may be pointed towards “hot” mirrors located between the user's eyes and the display panels that reflect IR or NIR light from the eyes to the eye tracking cameras while allowing visible light to pass. The eye tracking device130optionally captures images of the user's eyes (e.g., as a video stream captured at 60-120 frames per second (fps)), analyze the images to generate gaze tracking information, and communicate the gaze tracking information to the controller110. In some embodiments, two eyes of the user are separately tracked by respective eye tracking cameras and illumination sources. In some embodiments, only one eye of the user is tracked by a respective eye tracking camera and illumination sources.

In some embodiments, the eye tracking device130is calibrated using a device-specific calibration process to determine parameters of the eye tracking device for the specific operating environment100, for example the 3D geometric relationship and parameters of the LEDs, cameras, hot mirrors (if present), eye lenses, and display screen. The device-specific calibration process may be performed at the factory or another facility prior to delivery of the AR/VR equipment to the end user. The device-specific calibration process may be an automated calibration process or a manual calibration process. A user-specific calibration process may include an estimation of a specific user's eye parameters, for example the pupil location, fovea location, optical axis, visual axis, eye spacing, etc. Once the device-specific and user-specific parameters are determined for the eye tracking device130, images captured by the eye tracking cameras can be processed using a glint-assisted method to determine the current visual axis and point of gaze of the user with respect to the display, in some embodiments.

As shown inFIG.5, the eye tracking device130(e.g.,130A or130B) includes eye lens(es)520, and a gaze tracking system that includes at least one eye tracking camera540(e.g., infrared (IR) or near-IR (NIR) cameras) positioned on a side of the user's face for which eye tracking is performed, and an illumination source530(e.g., IR or NIR light sources such as an array or ring of NR light-emitting diodes (LEDs)) that emit light (e.g., IR or NTR light) towards the user's eye(s)592. The eye tracking cameras540may be pointed towards mirrors550located between the user's eye(s)592and a display510(e.g., a left or right display panel of a head-mounted display, or a display of a handheld device, a projector, etc.) that reflect IR or NIR light from the eye(s)592while allowing visible light to pass (e.g., as shown in the top portion ofFIG.5), or alternatively may be pointed towards the user's eye(s)592to receive reflected IR or NIR light from the eye(s)592(e.g., as shown in the bottom portion ofFIG.5).

In some embodiments, the controller110renders AR or VR frames562(e.g., left and right frames for left and right display panels) and provides the frames562to the display510. The controller110uses gaze tracking input542from the eye tracking cameras540for various purposes, for example in processing the frames562for display. The controller110optionally estimates the user's point of gaze on the display510based on the gaze tracking input542obtained from the eye tracking cameras540using the glint-assisted methods or other suitable methods. The point of gaze estimated from the gaze tracking input542is optionally used to determine the direction in which the user is currently looking.

The following describes several possible use cases for the user's current gaze direction, and is not intended to be limiting. As an example use case, the controller110may render virtual content differently based on the determined direction of the user's gaze. For example, the controller110may generate virtual content at a higher resolution in a foveal region determined from the user's current gaze direction than in peripheral regions. As another example, the controller may position or move virtual content in the view based at least in part on the user's current gaze direction. As another example, the controller may display particular virtual content in the view based at least in part on the user's current gaze direction. As another example use case in AR applications, the controller110may direct external cameras for capturing the physical environments of the XR experience to focus in the determined direction. The autofocus mechanism of the external cameras may then focus on an object or surface in the environment that the user is currently looking at on the display510. As another example use case, the eye lenses520may be focusable lenses, and the gaze tracking information is used by the controller to adjust the focus of the eye lenses520so that the virtual object that the user is currently looking at has the proper vergence to match the convergence of the user's eyes592. The controller110may leverage the gaze tracking information to direct the eye lenses520to adjust focus so that close objects that the user is looking at appear at the right distance.

In some embodiments, the eye tracking device is part of a head-mounted device that includes a display (e.g., display510), two eye lenses (e.g., eye lens(es)520), eye tracking cameras (e.g., eye tracking camera(s)540), and light sources (e.g., light sources530(e.g., IR or NIR LEDs)), mounted in a wearable housing. The illumination sources emit light (e.g., IR or NIR light) towards the user's eye(s)592. In some embodiments, the illumination sources may be arranged in rings or circles around each of the lenses as shown inFIG.5. In some embodiments, eight light sources530(e.g., LEDs) are arranged around each lens520as an example. However, more or fewer illumination sources530may be used, and other arrangements and locations of illumination sources530may be used.

In some embodiments, the display510emits light in the visible light range and does not emit light in the IR or NIR range, and thus does not introduce noise in the gaze tracking system. Note that the location and angle of eye tracking camera(s)540is given by way of example, and is not intended to be limiting. In some embodiments, a single eye tracking camera540is located on each side of the user's face. In some embodiments, two or more NIR cameras540may be used on each side of the user's face. In some embodiments, a camera540with a wider field of view (FOV) and a camera540with a narrower FOV may be used on each side of the user's face. In some embodiments, a camera540that operates at one wavelength (e.g., 850 nm) and a camera540that operates at a different wavelength (e.g., 940 nm) may be used on each side of the user's face.

Embodiments of the gaze tracking system as illustrated inFIG.5may, for example, be used in computer-generated reality, virtual reality, and/or mixed reality applications to provide computer-generated reality, virtual reality, augmented reality, and/or augmented virtuality experiences to the user.

FIG.6illustrates a glint-assisted gaze tracking pipeline, in some embodiments. In some embodiments, the gaze tracking pipeline is implemented by a glint-assisted gaze tracking system (e.g., eye tracking device130as illustrated inFIGS.1A and5). The glint-assisted gaze tracking system may maintain a tracking state. Initially, the tracking state is off or “NO”. When in the tracking state, the glint-assisted gaze tracking system uses prior information from the previous frame when analyzing the current frame to track the pupil contour and glints in the current frame. When not in the tracking state, the glint-assisted gaze tracking system attempts to detect the pupil and glints in the current frame and, if successful, initializes the tracking state to “YES” and continues with the next frame in the tracking state.

As shown inFIG.6, the gaze tracking cameras may capture left and right images of the user's left and right eyes. The captured images are then input to a gaze tracking pipeline for processing beginning at610. As indicated by the arrow returning to element600, the gaze tracking system may continue to capture images of the user's eyes, for example at a rate of 60 to 120 frames per second. In some embodiments, each set of captured images may be input to the pipeline for processing. However, in some embodiments or under some conditions, not all captured frames are processed by the pipeline.

At610, for the current captured images, if the tracking state is YES, then the method proceeds to element640. At610, if the tracking state is NO, then as indicated at620the images are analyzed to detect the user's pupils and glints in the images. At630, if the pupils and glints are successfully detected, then the method proceeds to element640. Otherwise, the method returns to element610to process next images of the user's eyes.

At640, if proceeding from element610, the current frames are analyzed to track the pupils and glints based in part on prior information from the previous frames. At640, if proceeding from element630, the tracking state is initialized based on the detected pupils and glints in the current frames. Results of processing at element640are checked to verify that the results of tracking or detection can be trusted. For example, results may be checked to determine if the pupil and a sufficient number of glints to perform gaze estimation are successfully tracked or detected in the current frames. At650, if the results cannot be trusted, then the tracking state is set to NO at element660, and the method returns to element610to process next images of the user's eyes. At650, if the results are trusted, then the method proceeds to element670. At670, the tracking state is set to YES (if not already YES), and the pupil and glint information is passed to element680to estimate the user's point of gaze.

FIG.6is intended to serve as one example of eye tracking technology that may be used in a particular implementation. As recognized by those of ordinary skill in the art, other eye tracking technologies that currently exist or are developed in the future may be used in place of or in combination with the glint-assisted eye tracking technology describe herein in the computer system101for providing XR experiences to users, in some embodiments.

In some embodiments, the captured portions of real world environment602are used to provide a XR experience to the user, for example, a mixed reality environment in which one or more virtual objects are superimposed over representations of real world environment602.

Thus, the description herein describes some embodiments of three-dimensional environments (e.g., XR environments) that include representations of real world objects and representations of virtual objects. For example, a three-dimensional environment optionally includes a representation of a table that exists in the physical environment, which is captured and displayed in the three-dimensional environment (e.g., actively via cameras and displays of a computer system, or passively via a transparent or translucent display of the computer system). As described previously, the three-dimensional environment is optionally a mixed reality system in which the three-dimensional environment is based on the physical environment that 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 is optionally able to selectively display portions and/or objects of the physical environment such that the respective portions and/or objects of the physical environment appear as if they exist in the three-dimensional environment displayed by the computer system. Similarly, the computer system is optionally able to display virtual objects in the three-dimensional environment to appear as if the virtual objects exist in the real world (e.g., physical environment) by placing the virtual objects at respective locations in the three-dimensional environment that have corresponding locations in the real world. For example, the computer system optionally displays a vase such that it appears as if a real vase is placed on top of a table in the physical environment. In some embodiments, a respective location in the three-dimensional environment has a corresponding location in the physical environment. Thus, when the computer system is described as displaying a virtual object at a respective location with respect to a physical object (e.g., such as a location at or near the hand of the user, or at or near a physical table), the computer system displays the virtual object at a particular location in the three-dimensional environment such that it appears as if the virtual object is at or near the physical object in the physical world (e.g., the virtual object is displayed at a location in the three-dimensional environment that corresponds to a location in the physical environment at which the virtual object would be displayed if it were a real object at that particular location).

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

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

In some embodiments, a user is optionally able to interact with virtual objects in the three-dimensional environment using one or more hands as if the virtual objects were real objects in the physical environment. For example, as described above, one or more sensors of the computer system optionally capture one or more of the hands of the user and display representations of the hands of the user in the three-dimensional environment (e.g., in a manner similar to displaying a real world object in three-dimensional environment described above), or in some embodiments, the hands of the user are visible via the display generation component via the ability to see the physical environment through the user interface due to the transparency/translucency of a portion of the display generation component that is displaying the user interface or due to projection of the user interface onto a transparent/translucent surface or projection of the user interface onto the user's eye or into a field of view of the user's eye. Thus, in some embodiments, the hands of the user are displayed at a respective location in the three-dimensional environment and are treated as if they were objects in the three-dimensional environment that are able to interact with the virtual objects in the three-dimensional environment as if they were physical objects in the physical environment. In some embodiments, the computer system is able to update display of the representations of the user's hands in the three-dimensional environment in conjunction with the movement of the user's hands in the physical environment.

In some of the embodiments described below, the computer system is optionally able to determine the “effective” distance between physical objects in the physical world and virtual objects in the three-dimensional environment, for example, for the purpose 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 within a threshold distance of a virtual object). For example, a hand directly interacting with a virtual object optionally includes one or more of a finger of a hand pressing a virtual button, a hand of a user grabbing a virtual vase, two fingers of a hand of the user coming together and pinching/holding a user interface of an application, and any of the other types of interactions described here. For example, the computer system optionally determines the distance between the hands of the user and virtual objects when determining whether the user is interacting with virtual objects and/or how the user is interacting with virtual objects. In some embodiments, the computer system determines the distance between the hands of the user and a virtual object by determining the distance between the location of the hands in the three-dimensional environment and the location of the virtual object of interest in the three-dimensional environment. For example, the one or more hands of the user are located at a particular position in the physical world, which the computer system optionally captures and displays at a particular corresponding position in the three-dimensional environment (e.g., the position in the three-dimensional environment at which the hands would be displayed if the hands were virtual, rather than physical, hands). The position of the hands in the three-dimensional environment is optionally compared with the position of the virtual object of interest in the three-dimensional environment to determine the distance between the one or more hands of the user and the virtual object. In some embodiments, the computer system optionally determines a 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 hands of the user and a virtual object, the computer system optionally determines the corresponding location in the physical world of the virtual object (e.g., the position at which the virtual object would be located in the physical world if it were a physical object rather than a virtual object), and then determines the distance between the corresponding physical position and the one of more hands of the user. In some embodiments, the same techniques are 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 techniques described above to map the location of the physical object to the three-dimensional environment and/or map the location of the virtual object to the physical environment.

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

Similarly, the embodiments described herein may refer to the location of the user (e.g., the user of the computer system) and/or the location of the computer system in the three-dimensional environment. In some embodiments, the user of the computer system is holding, wearing, or otherwise located at or near the computer system. Thus, in some embodiments, the 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 user in the physical environment corresponds to a respective location in the three-dimensional environment. For example, the location of the computer system would be the location in the physical environment (and its corresponding location in the three-dimensional environment) from which, if a user were to stand at that location facing a respective portion of the physical environment that is visible via the display generation component, the user would see the objects in the physical environment in the same positions, orientations, and/or sizes as they are displayed by or visible via the display generation component of the computer system in the three-dimensional environment (e.g., in absolute terms and/or relative to each other). Similarly, if the virtual objects displayed in the three-dimensional environment were physical objects in the physical environment (e.g., placed at the same locations in the physical environment as they are in the three-dimensional environment, and having the same sizes and orientations in the physical environment as in the three-dimensional environment), the location of the computer system and/or user is the position from which the user would see the virtual objects in the physical environment in the same positions, orientations, and/or sizes as they are displayed by the display generation component of the computer system in the three-dimensional environment (e.g., in absolute terms and/or relative to each other and the real world objects).

In the present disclosure, various input methods are described with respect to interactions with a computer system. When an example is provided using one input device or input method and another example is provided using another input device or input method, it is to be understood that each example may be compatible with and optionally utilizes the input device or input method described with respect to another example. Similarly, various output methods are described with respect to interactions with a computer system. When an example is provided using one output device or output method and another example is provided using another output device or output method, it is to be understood that each example may be compatible with and optionally utilizes the output device or output method described with respect to another example. Similarly, various methods are described with respect to interactions with a virtual environment or a mixed reality environment through a computer system. When an example is provided using interactions with a virtual environment and another example is provided using mixed reality environment, it is to be understood that each example may be compatible with and optionally utilizes the methods described with respect to another example. As such, the present disclosure discloses embodiments that are combinations of the features of multiple examples, without exhaustively listing all features of an embodiment in the description of each example embodiment.

User Interfaces and Associated Processes

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

FIGS.7A-7Hillustrate examples of providing feedback pertaining to device position adjustment.FIG.8is a flow diagram of an exemplary method800for providing feedback pertaining to device position adjustment. The user interfaces inFIGS.7A-7Hare used to illustrate the processes described below, including the processes inFIG.8.

FIG.7Adepicts electronic device700, which is a smartwatch that includes touch-sensitive display702, rotatable and depressible input mechanism704a, and button704b. In some embodiments described below, electronic device700is a smartwatch. In some embodiments, the user interfaces displayed by electronic device700are implemented on HMD X700. AtFIGS.7A-7H, HMD X700is represented by dashed lines to indicate that user interfaces displayed by electronic device700can also be implemented on HMD X700. In some embodiments, similar user interfaces could be implemented on a different electronic device such as a smartphone, a tablet, a wearable device, a head-mounted system (e.g., headset), and/or other computer system that includes and/or is in communication with one or more display devices (e.g., display screen and/or projection device). Electronic device700is a computer system (e.g., computer system101inFIG.1A).

AtFIG.7A, electronic device700and/or HMD X700is in a low power, inactive, and/or sleep state, in which content is not displayed via display702. AtFIG.7A, electronic device700and/or HMD X700detects user input706. In the depicted embodiments, user input706is a press input via rotatable and depressible input mechanism704a. However, in some embodiments, user input706is a different type of input, such as a gesture or other action taken by a user. For example, in some embodiments, electronic device700is a head-mounted system (e.g., HMD X700), and detecting user input706includes, for example, detecting that a user is putting and/or has put electronic device700and/or HMD X700on his or her head, detecting a gesture while electronic device700and/or HMD X700is worn, detecting a press of a button while electronic device700and/or HMD X700is worn, detecting rotation of a rotatable input mechanism while electronic device700and/or HMD X700is worn, detecting a gaze-based gesture (e.g., detecting the user looking at an object and/or moving his or her gaze in a particular manner), and/or any combination of the foregoing.

AtFIG.7B, in response to detecting user input706, electronic device700and/or HMD X700transitions from the low power, inactive, and/or sleep state to an active state in which electronic device700and/or HMD X700displays content via display702(e.g., a normal power state, a non-low power state, an activated state, and/or an awake state). AtFIG.7B, electronic device700and/or HMD X700detects (e.g., via one or more sensors) that a physical position of electronic device700and/or HMD X700satisfies one or more error conditions (e.g., is not positioned properly, is not positioned correctly, and/or the electronic device700and/or HMD X700should be moved (e.g., in order for electronic device700and/or HMD X700to operate properly and/or optimally)). In some embodiments, electronic device700and/or HMD X700detects that a physical position of electronic device700and/or HMD X700satisfies one or more error conditions relative to a portion of the body of a user (e.g., a user that is using and/or wearing electronic device700and/or HMD X700) (e.g., relative to a user's head, a user's face, and/or a portion of a user's face) (e.g., is not positioned properly relative to the portion of the body of the user, is not positioned correctly relative to the portion of the body of the user, and/or the electronic device700and/or HMD X700should be moved relative to the portion of the body of the user). For example, in some embodiments, electronic device700is a head-mounted system (e.g., HMD X700), and electronic device700and/or HMD X700detects that at least a portion of electronic device700and/or HMD X700is not positioned properly relative to the head and/or face of a user (e.g., should be moved relative to the head and/or face of a user). In some embodiments, electronic device700and/or HMD X700detects that at least a portion of electronic device700and/or HMD X700is not positioned properly relative to the face and/or eyes of the user, for example, for accurate gaze-based tracking (e.g., for gaze-based user inputs).

In the depicted embodiments, in response to user input706, and based on the determination that electronic device700satisfies one or more error conditions (e.g., relative to a portion of the body of the user), electronic device700and/or HMD X700displays, via display702, user interface707overlaid on three-dimensional environment708. In some embodiments, when electronic device700and/or HMD X700detects that electronic device700does not satisfy the one or more error conditions (e.g., relative to at least a portion of a body of a user) (e.g., electronic device700and/or HMD X700is positioned properly and/or electronic device700and/or HMD X700does not need to be moved (e.g., in order for electronic device700and/or HMD X700to operate properly and/or optimally)), electronic device700and/or HMD X700forgoes display of user interface707(e.g., displays a different user interface overlaid on three-dimensional environment708). In some embodiments, user interface707is an extended reality user interface overlaid on three-dimensional environment708. In the depicted embodiment, three-dimensional environment708includes objects708a,708b. In some embodiments, three-dimensional environment708is displayed by a display (as depicted inFIG.7B). In some embodiments, three-dimensional environment708includes a virtual environment or an image (or video) of a physical environment captured (e.g., in 3D) by one or more cameras (e.g., one or more cameras that are part of and/or in communication with electronic device700and/or HMD X700). In some embodiments, three-dimensional environment708is visible to a user behind user interface707, but is not displayed by a display. For example, in some embodiments, three-dimensional environment708is a physical environment that includes physical objects708a,708band is visible to a user (e.g., through a transparent display) behind user interface707without being displayed by a display.

AtFIG.7B, electronic device700and/or HMD X700determines that electronic device700and/or HMD X700should be moved to the left relative to a portion of a body of a user (e.g., a user wearing electronic device700and/or HMD X700). In response to this determination, user interface707includes prompt710instructing the user to move electronic device700and/or HMD X700“slightly to the left.” User interface707also includes adjustment indication712, which includes objects712aand712b. Object712ais representative of a current position of electronic device700and/or HMD X700, and object712bis representative of a target position (or goal position) for electronic device700and/or HMD X700. The position of object712arelative to object712bindicates the direction in which the user should move electronic device700and/or HMD X700. User interface707also includes arrow712c, indicating that the user should move electronic device700and/or HMD X700to the left (e.g., relative to the portion of the body of the user). Furthermore, inFIG.7B, in response to the determination that electronic device700and/or HMD X700should be moved to the left relative to a portion of the body of the user, electronic device700and/or HMD X700outputs audio output714-1on the left side of electronic device700and/or HMD X700(e.g., without outputting on the right side of electronic device700and/or HMD X700), and also outputs tactile (e.g., haptic) output716-1on the left side of electronic device700and/or HMD X700(e.g., without outputting on the right side of electronic device700and/or HMD X700).

AtFIG.7C, electronic device700and/or HMD X700detects that electronic device700and/or HMD X700has been moved slightly to the left (e.g., relative to at least a portion of the body of the user (e.g., relative to the head and/or face of the user)). In response to detecting that electronic device700and/or HMD X700has been moved to the left, electronic device700and/or HMD X700displays object712amoving to the left closer to object712b. In some embodiments, object712amoves to the left in conjunction with detecting movement of electronic device700and/or HMD X700to the left. In some embodiments, the amount of movement of object712ato the left is based on the amount of detected movement of electronic device700and/or HMD X700to the left. However, electronic device700and/or HMD X700still needs to be moved further to the left and, accordingly, object712aremains positioned to the right of object712b. Furthermore, based on a determination that electronic device700and/or HMD X700still needs to be moved further to the left, prompt710continues to instruct the user to move the device to the left, and electronic device700and/or HMD X700outputs audio output714-2on the left side of electronic device700(e.g., without outputting on the right side of electronic device700and/or HMD X700) and outputs tactile (e.g., haptic) output716-2on the left side of electronic device700and/or HMD X700(e.g., without outputting on the right side of electronic device700and/or HMD X700). In some embodiments, inFIG.7C, based on determination that electronic device700and/or HMD X700is closer to its target position than it was inFIG.7B, audio output714-2has a different volume (e.g., a lower volume or a higher volume) than audio output714-1, and/or tactile output716-2has a different magnitude (e.g., smaller magnitude or greater magnitude) than tactile output716-1.

At FIG.7D1, electronic device700and/or HMD X700detects that electronic device700and/or HMD X700has been moved further to the left (e.g., relative to at least a portion of the body of the user (e.g., relative to the head and/or face of the user)), but is now too far to the left. Accordingly, electronic device700and/or HMD X700determines that electronic device700nand/or HMD X700owshould be moved to the right. In response to the determination that electronic device700and/or HMD X700should be moved to the right, electronic device700and/or HMD X700updates display of prompt710to instruct the user to move electronic device700and/or HMD X700to the right, and also updates display of object712a, which now appears to the left of object712b, along with object712cwhich indicates that electronic device700and/or HMD X700should be moved to the right. Furthermore, in response to this determination, electronic device700and/or HMD X700now outputs audio output714-3and tactile (e.g., haptic) output716-3to the right side of electronic device700and/or HMD X700(e.g., without outputting on the left side of electronic device700and/or HMD X700). In some embodiments, in FIG.7D1, based on determination that electronic device700and/or HMD X700is farther from its target position than it was inFIG.7C, audio output714-3has a different volume (e.g., a lower volume or a higher volume) than audio output714-2, and/or tactile output716-3has a different magnitude (e.g., smaller magnitude or greater magnitude) than tactile output716-2.

In some embodiments, the techniques and user interface(s) described inFIGS.7A-7Hare provided by one or more of the devices described inFIGS.1A-IP. For example, FIG.7D2illustrates an embodiment in which prompt710(e.g., as described inFIGS.7B-7D1) is displayed on display module X702of head-mounted device (HMD) X700. In some embodiments, device X700includes a pair of display modules that provide stereoscopic content to different eyes of the same user. For example, HMD X700includes display module X702(which provides content to a left eye of the user) and a second display module (which provides content to a right eye of the user). In some embodiments, the second display module displays a slightly different image than display module X702to generate the illusion of stereoscopic depth.

At FIG.7D2, HMD X700detects that HMD X700has been moved further to the left (e.g., relative to at least a portion of the body of the user (e.g., relative to the head and/or face of the user)), but is now too far to the left. Accordingly, HMD X700determines that HMD X700now should be moved to the right. In response to the determination that HMD X700should be moved to the right, HMD X700updates display of prompt710to instruct the user to move HMD X700to the right, and also updates display of object712a, which now appears to the left of object712b, along with object712cwhich indicates that HMD X700should be moved to the right. Furthermore, in response to this determination, HMD X700now outputs audio output X714-3and tactile (e.g., haptic) output X716-3to the right side of HMD X700(e.g., without outputting on the left side of HMD X700). In some embodiments, in FIG.7D2, based on determination that HMD X700is farther from its target position than it was inFIG.7C, audio output X714-3has a different volume (e.g., a lower volume or a higher volume) than audio output714-2, and/or tactile output X716-3has a different magnitude (e.g., smaller magnitude or greater magnitude) than tactile output716-2.

Any of the features, components, and/or parts, including the arrangements and configurations thereof shown inFIGS.1B-1Pcan be included, either alone or in any combination, in HMD X700. For example, in some embodiments, HMD X700includes any of the features, components, and/or parts of HMD1-100,1-200,3-100,6-100,6-200,6-300,6-400,11.1.1-100, and/or11.1.2-100, either alone or in any combination. In some embodiments, display module X702includes any of the features, components, and/or parts of display unit1-102, display unit1-202, display unit1-306, display unit1-406, display generation component120, display screens1-122a-b, first and second rear-facing display screens1-322a,1-322b, display11.3.2-104, first and second display assemblies1-120a,1-120b, display assembly1-320, display assembly1-421, first and second display sub-assemblies1-420a,1-420b, display assembly3-108, display assembly11.3.2-204, first and second optical modules11.1.1-104aand11.1.1-104b, optical module11.3.2-100, optical module11.3.2-200, lenticular lens array3-110, display region or area6-232, and/or display/display region6-334, either alone or in any combination. In some embodiments, HMD X700includes a sensor that includes any of the features, components, and/or parts of any of sensors190, sensors306, image sensors314, image sensors404, sensor assembly1-356, sensor assembly1-456, sensor system6-102, sensor system6-202, sensors6-203, sensor system6-302, sensors6-303, sensor system6-402, and/or sensors11.1.2-110a-f, either alone or in any combination. In some embodiments, HMD X700includes one or more input devices, which include any of the features, components, and/or parts of any of first button1-128, button11.1.1-114, second button1-132, and or dial or button1-328, either alone or in any combination. In some embodiments, HMD X700includes one or more audio output components (e.g., electronic component1-112) for generating audio feedback (e.g., audio output X714-3), optionally generated based on detected events and/or user inputs detected by the HMD X700.

AtFIG.7E, electronic device700and/or HMD X700detects that it has been moved to the right (e.g., relative to at least a portion of the body of the user (e.g., relative to the head and/or face of the user)). In response to detecting movement of electronic device700and/or HMD X700to the right, electronic device700and/or HMD X700displays object712amoved further to the right. However, electronic device700and/or HMD X700detects that it should still be moved slightly further to the right. Accordingly, prompt710continues to state that the device should be moved to the right, object712aremains slightly to the left of object712b, and electronic device700and/or HMD X700outputs audio output714-4and tactile output716-4to the right side of electronic device700and/or HMD X700. In some embodiments, inFIG.7E, based on determination that electronic device700is closer to its target position than it was in FIGS.7D1and/or7D2, audio output714-4has a different volume (e.g., a lower volume or a higher volume) than audio output714-3and/or X714-3, and/or tactile output716-4has a different magnitude (e.g., smaller magnitude or greater magnitude) than tactile output716-3and/or X716-3.

AtFIG.7F, electronic device700and/or HMD X700detects that electronic device700and/or HMD X700has been moved further to the right, and is now at its target position (e.g., relative to at least a portion of the body of the user (e.g., relative to the head and/or face of the user)) such that electronic device700and/or HMD X700no longer satisfies the one or more error criteria. In response determining that electronic device700and/or HMD X700no longer satisfies the one or more error criteria, electronic device700and/or HMD X700ceases display of user interface707, and optionally displays prompt718indicating that electronic device700and/or HMD X700no longer satisfies the one or more error criteria (e.g., indicates that electronic device700and/or HMD X700is positioned correctly (e.g., relative to at least a portion of the body of the user (e.g., relative to the head and/or face of the user))). Furthermore, in response to determining that electronic device700and/or HMD X700no longer satisfies the one or more error criteria, electronic device700outputs audio output714-5and tactile output716-5(e.g., on both sides, on all sides, and/or on multiple sides) of electronic device700and/or HMD X700. In some embodiments, audio output714-5is different from (e.g., is a different sound from) audio outputs714-1through714-4. In some embodiments, tactile output716-5is different from (e.g., is a different vibration pattern) tactile outputs716-1through716-4.

While the depicted examples have shown example scenarios in which user interface707directs the user to move electronic device700and/or HMD X700(e.g., left, right, up, and/or down), in some embodiments, user interface707prompts a user to change one or more components of electronic device700and/or HMD X700. For example, in some embodiments, electronic device700is a head-mounted system (e.g., HMD X700) that includes a light seal component and/or a headband component, and user interface707instructs the user that the user should change the light seal component (e.g., from a first size and/or shape to a second size and/or shape) and/or the headband component (e.g., from a first size and/or shape to a second size and/or shape). In some embodiments, changing the light seal component (e.g., from a first size and/or shape to a second size and/or shape) and/or the headband component (e.g., from a first size and/or shape to a second size and/or shape) moves at least a portion of electronic device700and/or HMD X700further from and/or closer to the body (e.g., the head and/or the face) of the user. In some embodiments, a light seal component is a physical component that fits between the user's face and the computer system, a display device, and/or one or more display generation components to block out light (e.g., some light and/or all light) (e.g., external light and/or light that is not output by the computer system, a display device, and/or one or more display generation components) from reaching the eyes of the user. For example, in some embodiments, a light seal component creates a seal around the eyes of the user so that the user can see one or more display components without external light disrupting the user's view of the one or more display components. In some embodiments, a user is instructed to change the light seal component when electronic device700and/or HMD X700determines that the light seal component does not fit the face of the user properly and/or that the light seal is permitting greater than a threshold amount of light to enter an area (e.g., an area between the user's eyes and one or more display components) (e.g., greater than a threshold amount of light is detected by one or more sensors of the computer system).

In some embodiments, electronic device700and/or HMD X700forgoes display of user interface707while electronic device700and/or HMD X700is displaying certain types of content and/or while electronic device700and/or HMD X700is operating in a particular state, even if electronic device700and/or HMD X700satisfies the one or more error conditions. For example, inFIG.7G, electronic device700and/or HMD X700displays phone call user interface720indicating that electronic device700is currently engaged in an active phone call. Phone call user interface720includes contact name722a, phone call duration722b, mute button722c, options button722e, and end call button722d. InFIG.7G, electronic device700and/or HMD X700detects that electronic device700and/or HMD X700satisfies the one or more error conditions (e.g., electronic device700and/or HMD X700is not positioned properly (e.g., relative to at least a portion of the body of the user)). However, so as not to interrupt the experience of the user, electronic device700and/or HMD X700forgoes displaying user interface707while electronic device700and/or HMD X700is engaged in the phone call and/or while electronic device700and/or HMD X700is displaying user interface720. In some embodiments, electronic device700and/or HMD X700forgoes displaying user interface707when electronic device700and/or HMD X700is displaying a certain type of content (e.g., immersive content and/or content that occupies a threshold amount of display702(e.g., a full screen video or other user interface that occupies a threshold amount of the display (e.g., 25% of the display, 50% of the display, 75% of the display, 90% of the display, and/or 95% of the display))) and/or is operating in a certain state (e.g., is participating in an active communication session and/or is displaying immersive content).

AtFIG.7G, electronic device700and/or HMD X700detects user input724corresponding to selection of end call button722d, thereby ending the phone call. In the depicted embodiment, user input724is a touch input via touch-sensitive display702. However, in some embodiments, user input724is a different type of input, such as a gesture or other action taken by a user. For example, in some embodiments, electronic device700is a head-mounted system (e.g., HMD X70), and detecting user input724includes, for example, detecting a user performing a gesture (e.g., an air gesture) while electronic device700and/or HMD X700is worn, detecting a press of a button while electronic device700and/or HMD X700is worn, detecting rotation of a rotatable input mechanism while electronic device700and/or HMD X700is worn, detecting a gaze-based gesture (e.g., detecting the user looking at an object and/or moving his or her gaze in a particular manner), and/or any combination of the foregoing. AtFIG.7H, in response to detecting user input724, electronic device700and/or HMD X700ceases display of phone call user interface720and, based on a determination that electronic device700and/or HMD X700satisfies the one or more error criteria and that electronic device700and/or HMD X700is no longer displaying user interface720and/or participating in an active phone call, electronic device and/or HMD X700displays user interface707.

AtFIG.7H, user interface707indicates that electronic device700and/or HMD X700has determined that electronic device700and/or HMD X700should be moved to the left (e.g., relative to at least a portion of the body of the user), similar to the technique ofFIG.7B. In response to this determination, user interface707includes prompt710instructing the user to move electronic device700and/or HMD X700“slightly to the left.” User interface707also includes adjustment indication712, which includes objects712aand712b. Object712ais representative of a current position of electronic device700and/or HMD X700, and object712bis representative of a target position (or goal position) for electronic device700and/or HMD X700. The position of object712arelative to object712bindicates the direction in which the user should move electronic device700and/or HMD X700. User interface707also includes arrow712c, indicating that the user should move electronic device700and/or HMD X700to the left (e.g., relative to the portion of the body of the user). Furthermore, inFIG.7H, in response to the determination that electronic device700and/or HMD X700should be moved to the left relative to a portion of the body of the user, electronic device700and/or HMD X700outputs audio output714-6on the left side of electronic device700and/or HMD X700(e.g., without outputting on the right side of electronic device700and/or HMD X700), and also outputs tactile (e.g., haptic) output716-6on the left side of electronic device700and/or HMD X700(e.g., without outputting on the right side of electronic device700and/or HMD X700). As described above, in some embodiments, object712amoves in conjunction with electronic device700and/or HMD X700detecting movement of electronic device700and/or HMD X700.

Additional descriptions regardingFIGS.7A-7Hare provided below in reference to method800described with respect toFIG.8.

FIG.8is a flow diagram of an exemplary method800for providing feedback pertaining to device position adjustment, in some embodiments. In some embodiments, method800is performed at a computer system (e.g., computer system101inFIG.1A,700, and/or X700) in communication with or more display generation components (e.g., display generation component120inFIGS.1A,3, and4,702, and/or X702) (e.g., a heads-up display, a display, a touchscreen, a projector, a visual output device, a 3D display, a display having at least a portion that is transparent or translucent on which images can be projected (e.g., a see-through display), a projector, a heads-up display, and/or a display controller) and one or more input devices (e.g.,130,140,206,702,704a,704b) (e.g., a touch-sensitive surface (e.g., a touch-sensitive display); a mouse; a keyboard; a remote control; a visual input device (e.g., one or more cameras (e.g., an infrared camera, a depth camera, a visible light camera, and/or a gaze tracking camera)); an audio input device; a biometric sensor (e.g., a fingerprint sensor, a face identification sensor, a gaze tracking sensor, and/or an iris identification sensor) and/or one or more mechanical input devices (e.g., a depressible input mechanism; a button; a rotatable input mechanism; a crown; and/or a dial)). In some embodiments, method800is governed by instructions that are stored in a non-transitory (or transitory) computer-readable storage medium and that are executed by one or more processors of a computer system, such as the one or more processors202of computer system101(e.g., control110inFIG.1A). Some operations in method800are, optionally, combined and/or the order of some operations is, optionally, changed.

In some embodiments, the computer system (e.g.,700and/or X700) detects (802) a position of a portion of the computer system relative to a face of a user (e.g., relative to one or more features of a face of a user (e.g., relative to the eyes of the user and/or relative to the nose of the user)) (in some embodiments, the computer system is worn on the face of the user). In some embodiments, detecting the position of the portion of the computer system relative to the face of the user is performed in response to detecting that the computer system is worn on the face of the user. In response to detecting the position of the portion of the computer system relative to the face of the user (804) and in accordance with a determination that the computer system meets respective criteria while the position of the portion of the computer system relative to the face of the user meets one or more error conditions (e.g., the position of the portion of the computer system relative to the face of the user is determined to be faulty) (e.g., the computer system and/or the portion of the computer system is too far to the left on the face of the user, the computer system and/or the portion of the computer system is too far to the right on the face of the user, the computer system and/or the portion of the computer system is too high on the face of the user, the computer system and/or the portion of the computer system is too low on the face of the user, the computer system and/or the portion of the computer system is too close to the face of the user, and/or the computer system and/or the portion of the computer system is too far from the face of the user), wherein the respective criteria include a requirement that the computer system is operating in a respective context in order for the respective criteria to be met (e.g., the computer system is not displaying immersive content, the computer system is stationary, and/or the computer system is not being moved by the user) (e.g., computer system700and/or HMD X700is operating in the respective context inFIGS.7A-7F, but is not operating in the respective context inFIG.7G) (806), the computer system outputs (808) a first alert (e.g.,707,710,712a,712b,712c,714-1,714-2,714-3, X714-3,714-4,714-6,716-1,716-2,716-3, X716-3,716-4, and/or716-6) (e.g., a haptic alert, an audio alert, and/or a visual alert) indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions (e.g., an alert prompting the user to adjust the position of the computer system and/or the portion of the computer system relative to the face of the user and/or an alert prompting the user to replace and/or change one or more components of the computer system). In response to detecting the position of the portion of the computer system relative to the face of the user (804) and in accordance with a determination that the computer system does not meet the respective criteria (e.g., inFIG.7G) (e.g., the computer system is displaying immersive content, the computer system is not stationary, and/or the computer system is being moved by the user) while the position of the portion of the computer system relative to the face of the user meets the one or more error conditions (810), the computer system forgoes (812) outputting the first alert (e.g., until the device context criteria are satisfied) (e.g., inFIG.7G, computer system700and/or HMD X700does not display user interface707and/or does not output audio and/or haptic output indicating that computer system700and/or HMD X700satisfies the one or more error conditions).

In some embodiments, in response to detecting the position of the portion of the computer system relative to the face of the user, and in accordance with a determination that the position of the portion of the computer system relative to the face of the user does not meet the one or more errors conditions (e.g., the position of the portion of the computer system relative to the face of the user is not determined to be faulty and/or is determined to be correct), the computer system forgoes outputting the first alert (e.g.,FIG.7F).

In some embodiments, subsequent to forgoing outputting the first alert (e.g.,FIG.7G) (e.g., subsequent to detecting that the computer system does not meet the respective criteria while the position of the portion of the computer system relative to the face of the user meets the one or more errors conditions), and in accordance with a determination that the computer system meets the respective criteria while the position of the portion of the computer system relative to the face of the user meets the one or more error conditions, the computer system outputs the first alert (e.g., inFIG.7G, based on a determination that electronic device700and/or HMD X700does not meet the respective criteria, electronic device700and/or HMD X700forgoes outputting the first alert, and inFIG.7H, based on a determination that the computer system now meets the respective criteria, electronic device700and/or HMD X700outputs the first alert).

Outputting an alert that indicates that the position of the portion of the computer system relative to the face of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the device has determined that the position of the computer system relative to the face of the user meets one or more error conditions).

In some embodiments, subsequent to forgoing outputting the first alert in accordance with the determination that the computer system does not meet the respective criteria while the position of the portion of the computer system relative to the face of the user meets the one or more errors conditions (e.g.,FIG.7G), and in accordance with a determination that the computer system meets the respective criteria while the position of the portion of the computer system relative to the face of the user meets the one or more error conditions (e.g.,FIG.7H), the computer system outputs the first alert indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions (e.g., inFIG.7G, based on a determination that electronic device700and/or HMD X700does not meet the respective criteria, electronic device700and/or HMD X700forgoes outputting the first alert, and inFIG.7H, based on a determination that the computer system now meets the respective criteria, electronic device700and/or HMD X700outputs the first alert). Outputting an alert that indicates that the position of the portion of the computer system relative to the face of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the device has determined that the position of the computer system relative to the face of the user meets one or more error conditions).

In some embodiments, in response to detecting the position of the portion of the computer system relative to the face of the user, and in accordance with a determination that the position of the portion of the computer system relative to the face of the user does not meet the one more error conditions (e.g., the position of the portion of the computer system relative to the face of the user is determined to be correct; the computer system and/or the portion of the computer system is positioned properly relative to (e.g., on) the face of the user; and/or one or more metrics and/or sensor readings indicative of the position of the computer system and/or the portion of the computer system relative to the face of the user are within a predefined range of values), the computer system forgoes outputting the first alert (e.g.,707,710,712a,712b,712c,714-1,714-2,714-3, X714-3,714-4,714-6,716-1,716-2,716-3, X716-3,716-4, and/or716-6) (e.g.,FIG.7F). Outputting an alert when error conditions are met, and forgoing outputting the alert when error conditions are not met provides the user with visual feedback about a state of the device (e.g., whether or not the error conditions are met).

In some embodiments, outputting the first alert indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions comprises: outputting an initial alert (e.g.,707inFIG.7B,714-1, and/or716-1) (e.g., a visual initial alert and/or a non-visual (e.g., audio and/or haptic) initial alert) (e.g., an initial alert indicative of a first magnitude and/or a first direction (e.g., a first magnitude and/or first direction of movement needed to correct the position of the portion of the computer system relative to the face of the user)); while outputting the initial alert (e.g., while displaying the initial alert and/or while outputting a non-visual initial alert (e.g., audio and/or haptic output)), detecting, via the one or more input devices, first movement of the portion of the computer system relative to the face of the user (e.g., fromFIGS.7B to7C; from7C to7D2; and/or from7D1to7E); and in response to detecting the first movement of the portion of the computer system relative to the face of the user, outputting a revised alert (e.g.,707inFIG.7C,714-2,716-2,707in FIGS.7D1and/or7D2,714-3, X714-3,716-3, X716-3,707inFIG.7E,714-4, and/or716-4) (e.g., a visual revised alert and/or a non-visual (e.g., audio and/or haptic) revised alert) different from the initial alert based on the first movement of the portion of the computer system relative to the face of the user (e.g., a revised alert indicative of a second magnitude and/or a second direction (e.g., a second magnitude different from the first magnitude and/or a second direction different from the first direction) (e.g., a second magnitude and/or a second direction of movement needed to correct the position of the portion of the computer system relative to the face of the user)). In some embodiments, outputting the revised alert different from the initial alert comprises updating and/or replacing the initial alert. In some embodiments, while outputting the revised alert, the computer system detects, via the one or more input devices, second movement of the portion of the computer system relative to the face of the user; and in response to detecting the second movement of the portion of the computer system, the computer system outputs a second revised alert (e.g., a visual second revised alert and/or a non-visual (e.g., audio and/or haptic) second revised alert) different from the revised alert based on the second movement of the portion of the computer system relative to the face of the user (e.g., a second revised alert indicative of a third magnitude and/or a third direction (e.g., a third magnitude different from the second magnitude and/or a third direction different from the second direction) (e.g., a third magnitude and/or a third direction of movement needed to correct the position of the portion of the computer system relative to the face of the user)). Monitoring the position of the portion of the computer system relative to the face of the user and providing continuous feedback enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, outputting the first alert indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions comprises displaying, via the one or more display generation components, a visual alert (e.g.,707,710,712a,712b, and/or712c) indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions (e.g., a visual alert instructing the user to move the computer system and/or the portion of the computer system (e.g., relative to the face of the user); a visual alert instructing the user to move the computer system and/or the portion of the computer system in a first direction (e.g., relative to the face of the user); a visual alert indicating the magnitude by which the user should move the computer system and/or the portion of the computer system (e.g., relative to the face of the user); and/or a visual alert indicating that the user should replace one or more components of the computer system). In some embodiments, the visual alert indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions indicates a magnitude and/or direction corresponding to the one or more error conditions (e.g., a magnitude and/or direction to move the portion of the computer system (e.g., in order to stop meeting the one or more error conditions)). Displaying a visual alert that indicates that the position of the portion of the computer system relative to the face of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the device has determined that the position of the computer system relative to the face of the user meets one or more error conditions).

In some embodiments, outputting the first alert indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions comprises outputting a non-visual alert (e.g.,714-1through714-4,716-1through716-4,714-6, and/or716-6) (e.g., an audio alert, tactile alert, and/or a haptic alert) indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions (e.g., a non-visual alert indicating that the user should move the computer system and/or the portion of the computer system (e.g., relative to the face of the user); a non-visual alert indicating that the user should move the computer system and/or the portion of the computer system in a particular direction (e.g., relative to the face of the user) (e.g., audio output and/or haptic output coming from a first direction to indicate that the user should move the computer system in the first direction and/or audio output and/or haptic output coming from a second direction to indicate that the user should move the computer system in the second direction); a non-visual alert indicating that the user should move the computer system and/or the portion of the computer system by a first magnitude (e.g., relative to the face of the user) (e.g., a louder audio output and/or larger haptic output for larger magnitude of movement and/or a quieter audio output and/or smaller haptic output for smaller magnitude of movement); and/or a non-visual alert indicating that the user should replace one or more components of the computer system (e.g., an audio instruction to replace one or more components of the computer system)). In some embodiments, the non-visual alert indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions indicates a magnitude and/or direction corresponding to the one or more error conditions (e.g., a magnitude and/or direction to move the portion of the computer system (e.g., in order to stop meeting the one or more error conditions)). Outputting a non-visual alert that indicates that the position of the portion of the computer system relative to the face of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with feedback about a state of the device (e.g., the device has determined that the position of the computer system relative to the face of the user meets one or more error conditions). Additionally, if an error causes visual elements to be harder to view, a non-visual alert provides instructions that are not impacted by the error.

In some embodiments, outputting the first alert indicating that the position of the portion of the computer system relative to the face of the user meets the one or more error conditions comprises: outputting an alert indicating that a light seal component (e.g., a physical component (e.g., a physical component that fits between the user's face and the computer system, a display device, and/or one or more display generation components) to block out light (e.g., prevent light (e.g., some light and/or all light) (e.g., external light and/or light that is not output by the computer system, a display device, and/or one or more display generation components) from reaching the eyes of the user)) of the computer system meets one or more light seal error conditions (e.g., an alert indicating that the light seal component of the computer system does not fit the face of the user properly; an alert indicating that the light seal component of the computer system is permitting greater than a threshold amount of light to enter the computer system; and/or an alert indicating that greater than a threshold amount of light is detected by one or more sensors of the computer system) (e.g., prompt710and/or user interface707instructs the user to change the light seal component (e.g., from a first size and/or shape to a second size and/or shape)). In some embodiments, the one or more error conditions comprises a first condition that is met when greater than a threshold amount of light is detected by one or more sensors that are in communication with the computer system (e.g., one or more sensors that are indicative of the fit of a light seal component relative to the face of a user). Outputting an alert that indicates that a light seal component of the computer system meets one or more light seal error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, outputting the first alert (e.g.,707,710,712,714-1,714-2,714-3, X714-3,714-4,714-6,716-1,716-2,716-3, X716-3,716-4, and/or716-6) indicating that the position of the computer system relative to the face of the user meets the one or more error conditions comprises outputting an alert indicating that the eyes of the user are too close or too far from the portion of the computer system (e.g., the offset of the eyes of the user relative to the portion of the computer system (e.g., a display generation component and/or an eye box) is not within a threshold range of distances and/or offsets). Outputting an alert that indicates that the eyes of the user are too close or too far from the portion of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the respective criteria includes a content-type criterion that is met when the computer system is not outputting content of a first type (e.g., inFIG.7G, electronic device700and/or HMD X700is displaying an immersive user interface (e.g., that occupies greater than a threshold amount of the display), whereas inFIG.7H, electronic device700and/or HMD X700has ceased displaying immersive content) (e.g., is not outputting content and/or is outputting content of a second type different from the first type) (e.g., the computer system is not displaying content of the first type (e.g., visual content corresponding to an immersive experience (e.g., a video; a full-screen video; a game; a virtual reality game; and/or an active communication session (e.g., an active phone call or active video conference))); and/or the computer system is not playing audio content corresponding to an immersive experience (e.g., audio content corresponding to a video; a full screen video; a game; a virtual reality game; and/or an active communication session (e.g., an active phone call or active video conference))). Automatically outputting a first alert based on a determination that the computer system is not outputting content of a first type allows these operations to be performed automatically without further user input.

In some embodiments, the content of the first type is immersive experience content (e.g., inFIG.7G, electronic device700and/or HMD X700is displaying an immersive user interface (e.g., that occupies greater than a threshold amount of the display), whereas inFIG.7H, electronic device700and/or HMD X700has ceased displaying immersive content) (e.g., an immersive experience (e.g., a video; a full-screen video; a game; a virtual reality game; and/or an active communication session (e.g., an active phone call or active video conference))). In some embodiments, immersive experience content occupies greater than a threshold proportion of the field of view of the user (e.g., greater than 50%, greater than 75%, and/or greater than 90%). In some embodiments, immersive experience content cannot be displayed concurrently with other unrelated content and/or prevents concurrent display of other unrelated content (e.g., content generated by and/or pertaining to applications different from the immersive experience content) (in some embodiments, with the exception of certain predefined system user interface elements (e.g., operating system user interface elements) such as alerts, notifications, a home UI, a control center, a dock). Automatically outputting a first alert based on a determination that the computer system is not outputting immersive content, and automatically suppressing the first alert when the computer system is outputting immersive content, allows these operations to be performed automatically without further user input.

In some embodiments, subsequent to forgoing outputting the first alert in accordance with the determination that the computer system does not meet the respective criteria while the position of the portion of the computer system relative to the face of the user meets the one or more error conditions, the computer system detects that the computer system has ceased outputting content of the first type (e.g., inFIG.7G, electronic device700and/or HMD X700is displaying an immersive user interface (e.g., that occupies greater than a threshold amount of the display), whereas inFIG.7H, electronic device700and/or HMD X700has ceased displaying immersive content) (e.g., has transitioned from outputting content of the first type to no longer outputting content of the first type); and in response to detecting that the computer system has ceased outputting content of the first type, the computer system outputs the first alert (e.g., inFIG.7H, electronic device700and/or HMD X700outputs the first alert (e.g.,707,710,712,714-6, and/or716-6)). Automatically outputting a first alert once content of the first type is no longer being output, allows these operations to be performed automatically without further user input. Furthermore, doing so also provides the user with instructions for correcting the error as soon as possible without interrupting the user's experience, thereby improving the operability of the device.

In some embodiments, the respective criteria includes a stability criterion that is met when the computer system meets stability criteria relative to the face of the user (e.g., the computer system is moving less than a threshold amount (e.g., at less than a threshold speed (e.g., 0.9 m/s, 0.1 m/s, 0.01 m/s, and/or 0.001 m/s), with less than a threshold acceleration (e.g., less than 1 m/s/s, less than 0.1 m/s/s, and/or less than 0.01 m/s/s), and/or less than a threshold magnitude (e.g., less than 5 cm, less than 1 cm, less than 0.5 cm, less than 0.1 cm, less than 0.05 cm, and/or less than 0.01 cm)) relative to the face of the user) (e.g., inFIG.7B, had the user still been moving electronic device700and/or HMD X700(e.g., user is still putting electronic device on his or her head), electronic device700and/or HMD X700would forgo display of user interface707and/or output of audio output714-1and/or tactile output716-1). In some embodiments, the determination that the computer system does not meet respective criteria comprises a determination that the computer system does not meet the stability criteria relative to the face of the user (e.g., the computer system is moving greater than a threshold amount (e.g., at greater than a threshold speed, with greater than a threshold acceleration, and/or greater than a threshold magnitude) relative to the face of the user). Outputting an alert that indicates that the position of the portion of the computer system relative to the face of the user meets one or more error conditions when it is determined that the computer system meets stability criteria relative to the face of the user enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the first alert comprises a suggestion (e.g., an instruction and/or an indication) to replace one or more hardware components of the computer system with a different hardware component (e.g., user interface707and/or prompt710includes an instruction to replace one or more hardware components of the computer system) (e.g., a hardware component of the same type with a different size and/or shape) (e.g., a light seal component, a display generation component, an ear seal component, and/or a headband component). Outputting an alert suggesting that the user change one or more hardware components of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the device has determined that one or more hardware components should be changed).

In some embodiments, the first alert comprises a suggestion (e.g., an instruction and/or an indication) to change one or more settings of the computer system (e.g., user interface707and/or prompt710includes an instruction to change one or more settings of the computer system) (e.g., an interpupillary distance setting and/or one or more display settings). Outputting an alert suggesting that the user change one or more settings of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the device has determined that one or more settings should be changed).

In some embodiments, the first alert (e.g.,707,710,712,712a,712b,712c,714-1,714-2,714-3, X714-3,714-4,714-6,716-1,716-2,716-3, X716-3,716-4, and/or716-6) comprises a suggestion (e.g., an instruction and/or an indication) to move the portion of the computer system relative to the face of the user (e.g., a suggestion to move the portion of the computer system to the right, to the left, up, and/or down). Outputting an alert suggesting that the user move the portion of the computer system relative to the face of the user enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the device has determined that the device should be moved relative to the face of the user).

In some embodiments, aspects/operations of methods800and/or1000may be interchanged, substituted, and/or added between these methods. For example, in some embodiments, the computer system in method800is the computer system in method1000. For brevity, these details are not repeated here.

The user interfaces inFIGS.9A-9Gare used to illustrate the processes inFIG.10.

FIG.9Adepicts electronic device900, which includes display902, one or more input sensors904(e.g., one or more cameras, eye gaze trackers, hand movement trackers, and/or head movement trackers), and physical input devices1506a-1506c. In some embodiments, electronic device900is a smart phone, a tablet a wearable device, a wearable smartwatch device, a head-mounted system (e.g., a headset), or other computer system that includes and/or is in communication with one or more display devices (e.g., display screen, projection device, or the like). In some embodiments, the techniques and user interfaces described inFIGS.9A-9Gare provided by one or more of the devices described inFIGS.1A-IP. In some embodiments, electronic device900includes a pair of display modules that provide stereoscopic content to different eyes of the same user. For example, electronic device900includes display module902(which provides content to a left eye of the user) and a second display module (which provides content to a right eye of the user). In some embodiments, the second display module displays a slightly different image than display module902to generate the illusion of stereoscopic depth.

Any of the features, components, and/or parts, including the arrangements and configurations thereof shown inFIGS.1B-1Pcan be included, either alone or in any combination, in electronic device900. For example, in some embodiments, electronic device900includes any of the features, components, and/or parts of HMD1-100,1-200,3-100,6-100,6-200,6-300,6-400,11.1.1-100, and/or11.1.2-100, either alone or in any combination.

In some embodiments, input sensor904includes any of the features, components, and/or parts of any of sensors190, sensors306, image sensors314, image sensors404, sensor assembly1-356, sensor assembly1-456, sensor system6-102, sensor system6-202, sensors6-203, sensor system6-302, sensors6-303, sensor system6-402, and/or sensors11.1.2-110a-f, either alone or in any combination. In some embodiments, mechanical input devices906a-906cinclude any of the features, components, and/or parts of any of first button1-128, button11.1.1-114, second button1-132, and or dial or button1-328, either alone or in any combination. In some embodiments, electronic device900includes one or more audio output components (e.g., electronic component1-112) for generating audio feedback, optionally generated based on detected events and/or user inputs detected by the electronic device900. Electronic device900is a computer system (e.g., computer system101inFIG.1A).

AtFIG.9A, electronic device900displays, via display902, user interface910corresponding to a first application and user interface912corresponding to a second application overlaid on three-dimensional environment908which, in the depicted scenario, includes objects908a,908b. In some embodiments, three-dimensional environment908is displayed by a display (e.g., display902). In some embodiments, three-dimensional environment908includes a virtual environment or an image (or video) of a physical environment captured by one or more cameras (e.g., one or more cameras that are part of input sensors904and/or one or more external cameras). For example, in some embodiments, object908ais a virtual object that is representative of a physical object that has been captured by one or more cameras and/or detected by one or more sensors; and object908bis a virtual object that is representative of a second physical object that has been captured by one or more cameras and/or detected by one or more sensors, and so forth. In some embodiments, three-dimensional environment908is visible to a user through display902but is not displayed by a display. For example, in some embodiments, three-dimensional environment908is a physical environment (and, for example, objects908a-908bare physical objects) that is visible to a user (e.g., through one or more transparent displays (e.g.,902) without being displayed by a display.

In various depicted embodiments, electronic device900is configured to detect one or more error conditions pertaining to the position of electronic device900relative to a portion of the body of a user. For example, in some embodiments, electronic device900is a head-mounted system, and electronic device900is configured to detect one or more error conditions pertaining to the position of electronic device900relative to the face of a user and/or one or more facial features of the user (e.g., the eyer of the user and/or the nose of the user). In certain embodiments, a first group of error conditions and/or a first type of error conditions results in a first type of alert, and a second group of error conditions and/or a second type of error conditions results in a second type of alert that is different from the first type of alert. In some embodiments, the second group of error conditions and/or the second type of error conditions is considered to be more serious, and the second type of alert is more difficult to dismiss than the first type of alert, and/or the second type of alert requires and/or demands more of the user's attention.

AtFIG.9B, electronic device900detects that the position of electronic device900relative to the body of the user (e.g., the face of the user) satisfies a first set of error criteria corresponding to the first type of error conditions. In some embodiments, the first type of error conditions is considered less important or less serious. For example, in some embodiments, the first type of error conditions includes determining that electronic device900should be moved to the right, to the left, up, and/or down on the face of the user. In some embodiments, the first type of error conditions includes determining that electronic device900should be moved closer to the face of the user. In some embodiments, electronic device900is moved closer to or further away from the face of the user by changing one or more components (e.g., hardware components) of electronic device900. For example, in some embodiments, electronic device900is moved closer to or further away from the face of the user by changing a light seal component of electronic device900(e.g., light seal1-110and/or light seal1-210) for a different light seal component that has different physical dimensions. AtFIG.9B, based on a determination that that the position of electronic device900satisfies the first set of error criteria corresponding to the first type of error conditions, electronic device900displays alert914that notifies the user that the position of electronic device900satisfies one or more error conditions. In some embodiments, alert914provides the user with instructions as to how to rectify and/or correct the error condition. For example, alert914instructs the user to move electronic device900to the left, to the right, up, and/or down on the face of the user. In some embodiments, alert914instructs the user to change a light seal component of electronic device900for a different light seal component.

In some embodiments, alert914is displayed as an environment-locked object. AtFIG.9C, the viewpoint of electronic device900changes (e.g., based on movement of the user's head as the user wears electronic device900on his or her head). Alert914, being an environment-locked object, maintains its position within three-dimensional environment908as the viewpoint of electronic device900and/or the viewpoint of the user changes. AtFIG.9D, electronic device900detects that the position of electronic device900no longer satisfies the first set of error criteria relative to the portion of the body of the user. For example, atFIG.9D, the user shifts the position of electronic device900on his or her face such that it is now positioned correctly. In response to detecting that the position of electronic device900no longer satisfies the first set of error criteria relative to the portion of the body of the user, electronic device900ceases display of alert914.

AtFIG.9E, electronic device900detects that the position of electronic device900relative to the body of the user (e.g., the face of the user) satisfies a second set of error criteria corresponding to a second type of error conditions. In some embodiments, the second type of error conditions is considered more important or more serious than the first type of error conditions. For example, in some embodiments, the second type of error conditions includes determining that one or more components of electronic device900are too close to one or more portions of the user's face (e.g., display902is too close to the faces, eyes and/or the nose of the user). AtFIG.9E, in response to detecting that the position of electronic device900satisfies the second set of error conditions, electronic device900displays alert916. In some embodiments, alert916informs the user that the position of electronic device900satisfies the second set of error criteria. In some embodiments, alert916instructs the user on how to correct the error. For example, in some embodiments, alert916instructs the user to change a component (e.g., a light seal component or other component) or electronic device900, and provides the user with a URL to order the component. In some embodiments, alert916requires user input (e.g., on option916a) to dismiss alert916and alert916is not dismissed automatically. Furthermore, in the depicted embodiments, alert916is displayed as viewpoint-locked object. AtFIG.9F, the viewpoint of electronic device900changes (e.g., based on movement of the user's head as the user wears electronic device900on his or her head). However, alert916, as a viewpoint-locked object, remains in the same display position relative to the viewpoint of the user. In some embodiments, while alert916is displayed, one or more features of electronic device900are unavailable. For example, in some embodiments, while alert916is displayed, a user is not able to interact with user interface window910or user interface window912. In some embodiments, when alert914ofFIG.9Cis displayed, the one or more features of electronic device remain available to the user. For example, inFIG.9C, while alert914is displayed, a user is still able to interact with window910and window912.

In some embodiments, electronic device900outputs different sets of alerts based on an operating state of electronic device900. For example, in some embodiments, electronic device900is operable in an authorized user state or in a guest state. In the guest state, an authorized user has allowed an unauthorized user to use electronic device900in the guest state, and electronic device900provides access to fewer features and/or less content than when electronic device900is operated in the authorized user state. In some embodiments, certain types of alerts are displayed the same in the authorized user state and the guest state. For example, in some embodiments, an alert instructing the user to move the device up, down, left, or right on the user's face is displayed in both operating states. However, in some embodiments, certain alerts are displayed differently in the two operating states. For example, in some embodiments, in the authorized user state of operation, electronic device900instructs the user to change a physical component of electronic device900and/or order a new physical component. However, in the guest state of operation, electronic device900does not instruct the user to order a new physical component, but rather informs the user that the user's experience may be sub-optimal due to one or more error conditions. InFIG.9G, electronic device900is operating in the guest state of operation, and displays indication918indicating that electronic device900is operating in the guest state of operation. While in the guest state of operation, electronic device900detects that the position of electronic device900relative to a portion of the body of the user satisfies error criteria. In response, electronic device900displays alert920. In some embodiments, alert920is different from alert920and/or alert916based on a determination that electronic device900is operating in the guest state of operation (and not an authorized user state of operation).

FIG.10is a flow diagram of an exemplary method1000for providing feedback pertaining to device position adjustment, in some embodiments. In some embodiments, method1000is performed at a computer system (e.g., computer system101inFIG.1and/or electronic device900) (e.g., a smart phone, a smart watch, a tablet, a laptop, a desktop, a wearable device, and/or head-mounted device) that is in communication with one or more display generation components (e.g.,902) (e.g., display generation component120inFIGS.1,3, and4) (e.g., a visual output device, a 3D display, a display having at least a portion that is transparent or translucent on which images can be projected (e.g., a see-through display), a projector, a heads-up display, and/or a display controller) and one or more input devices (e.g.,902,904, and/or906a-906c) (e.g., a touch-sensitive surface (e.g., a touch-sensitive display); a mouse; a keyboard; a remote control; a visual input device (e.g., one or more cameras (e.g., an Infrared camera, a depth camera, a visible light camera, and/or a gaze tracking camera)); an audio input device; a biometric sensor (e.g., a fingerprint sensor, a face identification sensor, a gaze tracking sensor, and/or an iris identification sensor) and/or one or more mechanical input devices (e.g., a depressible input mechanism; a button; a rotatable input mechanism; a crown; and/or a dial)). In some embodiments, method1000is governed by instructions that are stored in a non-transitory (or transitory) computer-readable storage medium and that are executed by one or more processors of a computer system, such as the one or more processors202of computer system101(e.g., control110inFIG.1). Some operations in method1000are, optionally, combined and/or the order of some operations is, optionally, changed.

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

In response (1004) to detecting the position of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user and in accordance with a determination that the position of the portion of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user meets a first set of error conditions (e.g., in accordance with a determination that the position of the portion of the computer system is too high, too low, too far to the left, and/or too far to the right relative to a target position of the portion of the computer system relative to the body (e.g., face) of the user (e.g., relative to one or more features of the face of the user); and/or in accordance with a determination that the position of the portion of the computer system is too far from and/or too close to the body (e.g., face) of the user (e.g., relative to one or more features and/or a portion of the face of the user)) (e.g., a first set of error conditions that may result in decreased user input accuracy (e.g., decreased gaze input accuracy and/or other input accuracy) and/or a first set of error conditions that represent a potential safety hazard to the user), the computer system (e.g.,900) displays (1006), via the one or more display generation components (e.g.,902), a first alert (e.g.,916) indicating that the position of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user satisfies the first set of error conditions (e.g., an alert notifying the user that user input may have decreased accuracy, an alert notifying the user of a potential safety hazard to the user, an alert prompting the user to adjust the position of the computer system relative to the face of the user, and/or an alert prompting the user to replace and/or change one or more components of the computer system), wherein the first alert prevents access to one or more features of the computer system until the first alert is dismissed (e.g., until the user performs one or more functions to dismiss the first alert and/or until the first set of error conditions is no longer satisfied).

In response (1004) to detecting the position of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user and in accordance with a determination that the position of the portion of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user meets a second set of error conditions different from the first set of error conditions (e.g., in accordance with a determination that the position of the portion of the computer system is too high, too low, too far to the left, and/or too far to the right relative to a target position of the portion of the computer system relative to the body (e.g., face) of the user (e.g., relative to one or more features of the face of the user); and/or in accordance with a determination that the position of the portion of the computer system is too far from and/or too close to the body (e.g., face) of the user (e.g., relative to one or more features and/or a portion of the face of the user)) (e.g., a second set of error conditions that may result in decreased user input accuracy (e.g., decreased gaze input accuracy and/or other input accuracy) and/or a second set of error conditions that do not pose a potential safety hazard to the user), the computer system (e.g.,900) displays (1008), via the one or more display generation components, a second alert (e.g.,914) indicating that the position of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user satisfies the second set of error conditions (e.g., an alert notifying the user that user input may have decreased accuracy, an alert notifying the user of a potential safety hazard to the user, an alert prompting the user to adjust the position of the computer system relative to the face of the user, and/or an alert prompting the user to replace and/or change one or more components of the computer system) (e.g., without displaying the first alert), wherein the second alert is different from the first alert, and the one or more features of the device can be accessed while the second alert is displayed. Outputting a first alert or a second alert based on a determination that the position of the portion of the computer system relative to the body of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the computer system has determined that the position of the computer system relative to the body of the user meets one or more error conditions). Providing such alerts can also improve user safety, by notifying the user of potential safety issues that could arise from the one or more error conditions. Providing a first alert that prevents access to one or more features of the computer system until the alert is dismissed also enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the first alert (e.g.,916) is a viewpoint-locked object and the second alert (e.g.,914) is an environment-locked object. In some embodiments, the first alert is a viewpoint-locked object that exhibits lazy-follow behavior (e.g., follows the viewpoint of the user after a delay and/or after more than a threshold amount of movement by the user). Outputting a first alert or a second alert that indicates that the position of the portion of the computer system relative to the body of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the computer system has determined that the position of the computer system relative to the body of the user meets one or more error conditions).

In some embodiments, the first alert (e.g.,916) requires one or more user inputs (e.g., one or more touch inputs, one or more gesture inputs, one or more air gesture inputs, and/or one or more hardware inputs) interacting with a user interface (e.g.,916a) to dismiss (e.g., to cease display of) the first alert (e.g., one or more user inputs selecting one or more objects and/or interacting with one or more objects in a displayed user interface) and the second alert (e.g.,914) does not require user inputs interacting with a user interface to dismiss the second alert (e.g., the second alert is automatically dismissed and/or automatically ceases to be displayed when the second set of error conditions ceases to be met). Outputting a first alert or a second alert that indicates that the position of the portion of the computer system relative to the face of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the device has determined that the position of the computer system relative to the face of the user meets one or more error conditions). Providing such alerts, and making certain alerts (e.g., the first alert) more difficult to dismiss, can also improve user safety, by notifying the user of potential safety issues that could arise from the one or more error conditions. Providing a first alert that prevents access to one or more features of the computer system until the alert is dismissed also enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the determination that the position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions includes a determination that the position of the portion of the computer system (e.g.,900) is too far to the left, too far too the right, too high, and/or too low relative to a portion of the body of the user (e.g., relative to the face of the user; and/or relative to one or more features and/or a portion of the face of the user). Outputting a second alert based on a determination that the computer system is too far to the left, too far to the right, too high, and/or too low relative to a portion of the body of a user enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the computer system has determined that the computer system is too far to the left, too far to the right, too high, and/or too low relative to a portion of the body of the user).

In some embodiments, when the second set of error conditions is met (e.g.,FIG.9B), gaze tracking of one or more eyes of the user is less accurate (e.g., less precise) than when the second set of error conditions is not met. In some embodiments, when the second set of error conditions is met, gaze tracking accuracy is affected (e.g., negatively affected). Outputting a second alert based on a determination that a set of error conditions that negatively affect gaze tracking accuracy makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the computer system has determined that the computer system meets a set of error criteria that negatively affects gaze tracking accuracy).

In some embodiments, at a first time, in accordance with a determination that the position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions, the computer system (e.g.,900) displays, via the one or more display generation components, the second alert (e.g.,914). In some embodiments, at a second time subsequent to the first time, and while the second alert is displayed, in accordance with a determination that the position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user no longer meets the second set of error conditions, the computer system (e.g.,900) ceases display of the second alert (e.g.,FIG.9D) (e.g., automatically and/or without user input). In some embodiments, while displaying the second alert, the computer system detects movement of the portion of the computer system to a new position relative to the portion of the body of the user; and subsequent to detecting movement of the portion of the computer system to a new position relative to the portion of the body of the user, in accordance with a determination that the new position does not meet the second set of error conditions, the computer system ceases display of the second alert. Automatically ceasing display of the second alert when the second set of error conditions is not met allows for this operation to be performed with fewer and/or no user inputs. Ceasing display of the second alert when the second set of error conditions is no longer met also makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the computer system has determined that the second set of error conditions is no longer met).

In some embodiments, while detecting the position of the portion of the computer system relative to the portion of the body of the user, the computer system (e.g.,900) displays, via the one or more display generation components, first content (e.g.,910and/or912) in a first manner (e.g.,FIG.9A) (e.g., a first manner that indicates that the first content is currently selected and/or currently in focus, a first brightness, a first saturation, a first opacity, a first contrast, a first focus, and/or a first sharpness). In response to detecting the position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user: in accordance with a determination that the position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the first set of error conditions (e.g.,FIG.9E), the computer system (e.g.,900) displays the first content (e.g.,910and/or912) in a second manner (e.g.,FIG.9E) different from the first manner (or, in some embodiments, ceasing display of at least a portion of the first content) (e.g., a second manner that indicates that the first content is not currently selected and/or not in focus, a second brightness, a second saturation, a second opacity, a second contrast, a second focus, a second sharpness, and/or a second manner that visually deemphasizes the first content compared to the first manner (e.g., decreased brightness, decreased saturation, decreased sharpness, and/or decreased opacity)) (e.g., displaying the first content in the second manner while displaying the first alert and/or while concurrently displaying the first alert) and in accordance with a determination that the position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions, the computer system (e.g.,900) maintains display of the first content (e.g.,910and/or912) in the first manner (e.g.,FIG.9B) (e.g., while displaying the second alert and/or while concurrently displaying the second alert). Displaying the first content in the second manner when the first alert is displayed draws the user's attention to the first alert, which enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, displaying the first content (e.g.,910and/or912) in the second manner (e.g.,FIG.9E) comprises displaying the first content in a second manner that visually deemphasizes the first content compared to the first manner (e.g., decreased brightness, decreased saturation, decreased sharpness, and/or decreased opacity compared to the first manner). In some embodiments, displaying the first content in the second manner comprises fading out the first content. Visually deemphasizing and/or fading out the first content when the first is displayed enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, while displaying the first content (e.g.,910and/or912), the computer system (e.g.,900) receives, via the one or more input devices, a first user input (e.g., one or more touch inputs, one or more gesture inputs, one or more air gesture inputs, one or more gaze-based inputs, and/or one or more hardware inputs). In response to receiving the first user input: in accordance with a determination that the first content is displayed in the first manner (e.g.,FIG.9Aand/orFIG.9B) (e.g., while the second set of error conditions is met, while the first set of error conditions is not met, while the second alert is displayed, while the first alert is not displayed, while the first and second sets of error conditions are not met, and/or while the first and second alerts are not displayed), the computer system (e.g.,900) modifies display of the first content in response to the first user input; and in accordance with a determination that the first content is displayed in the second manner (e.g.,FIG.9E) (e.g., while the first set of error conditions is met and/or while the first alert is displayed), the computer system (e.g.,900) forgoes modifying display of the first content in response to the first user input. In some embodiments, while the first alert is displayed, a user is prevented from and/or prohibited from interacting with the first content until the first alert is dismissed and/or until the first alert ceases to be displayed. Preventing user interaction with the first content while the first alert is displayed and/or while the first content is displayed in the second manner enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the determination that the position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the first set of error conditions includes a determination that the portion of the computer system (e.g.,900) is too close to one or more eyes of the user (e.g., is less than a threshold distance away from the one or more eyes of the user (e.g., less than 8 cm, less than 7 cm, less than 6 cm, less than 5 cm, less than 4 cm, less than 3 cm, less than 2 cm, or less than 1 cm)). In some embodiments, a light seal component (e.g.,1-110and/or1-210) extends the computer system away from the eyes of the user and/or determines (at least in part) the distance of the portion of the computer system from the one or more eyes of the user. In some embodiments, the light seal component (e.g.,1-110and/or1-210) is a physical component that fits between the user's face and the computer system, a display device, and/or one or more display generation components to block out light (e.g., prevent light (e.g., some light and/or all light) (e.g., external light and/or light that is not output by the computer system, a display device, and/or one or more display generation components) from reaching the eyes of the user. In some embodiments, the determination that the portion of the computer system is too close to one or more eyes of the user comprises a determination that a light seal component (e.g.,1-110and/or1-210) having different physical dimensions (e.g., a larger depth) should be used by the user. Outputting a first alert based on a determination that the computer system is too close to the user's eyes enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the computer system has determined that the computer system is too close to the eyes of the user). Providing such alerts can also improve user safety, by notifying the user of potential safety issues that could arise from the one or more error conditions.

In some embodiments, when the first set of error conditions is met (e.g.,FIG.9E), the user is using the computer system in a way that is has a reduced margin of safety (e.g., degree of safety) compared to when the first set of error conditions is not met. In some embodiments, the first set of error conditions is indicative of the device being used in a way that has a reduced margin of safety relative to standard, expected, and/or recommended usage. In some embodiments, the first set of error conditions correspond to eye safety. In some embodiments, the first set of error conditions implement and/or correspond to industry best practices to ensure that the computer system is being operated safely and to ensure user safety. In some embodiments, the first set of error conditions, the second set of error conditions, the first alert, and/or the second alert represent an effort to implement industry best practices to ensure that the computer system is being operated safely and to ensure user safety. For example, in some embodiments, the first alert and/or the second alert notify the user when there is a potential risk for user safety, and notify the user of steps that can be taken to minimize and/or substantially eliminate risk of user safety and/or direct the user to resources to ensure that the user is using the device in the safest possible manner. In some embodiments, when the second set of error conditions is met, the user is operating the device within a standard margin of safety. In some embodiments, operation of the device is more safe when the second set of error conditions is met than when the first set of error conditions is met. Outputting a first alert based on a determination that a set of error conditions that could negatively affect the safety of the user's eyes improves user safety. Doing so also enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device.

In some embodiments, the first alert (e.g.,916) directs the user to one or more resources for addressing the first set of error conditions (e.g., directs the user to one or more resources that can assist the user to fix and/or address the first set of error conditions). In some embodiments, the one or more resources include one or more URL links. In some embodiments, the one or more resources include contact information (e.g., email address, phone number, physical address, and/or social media handle) for one or more entities. Providing the user with one or more resources for addressing the first set of error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the one or more resources direct the user to a first store (e.g., a physical store and/or an online store) (e.g., a URL for accessing an online store) for acquiring (e.g., purchasing and/or exchanging) a first accessory (e.g., a first physical accessory and/or a first physical part (e.g., a first light seal (e.g.,1-110and/or1-210) (e.g., a physical component (e.g., a physical component that fits between the user's face and the computer system, a display device, and/or one or more display generation components) to block out light (e.g., prevent light (e.g., some light and/or all light) (e.g., external light and/or light that is not output by the computer system, a display device, and/or one or more display generation components) from reaching the eyes of the user))) for addressing the first set of error conditions. Providing the user with one or more resources for addressing the first set of error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the computer system (e.g.,900) detects that the user has stopped using the computer system (e.g.,900) (e.g., detecting that the user has taken the computer system off of his or her body and/or one or more portions of the body of the user are no longer at a particular position with respect to one or more portions of the computer system (e.g., one or more eyes of the user are no longer detected in front of the one or more display generation components and/or are no longer detected within an eye box of the computer system)). Subsequent to detecting that the user has stopped using the computer system (e.g.,900), the computer system (e.g.,900) detects that the user has resumed using the computer system (e.g.,900) (e.g., detecting that the user has worn the computer system on his or her body and/or one or more portions of the body of the user are detected at a particular position with respect to one or more portions of the computer system (e.g., one or more eyes of the user are detected in front of the one or more display generation components and/or are detected within an eye box of the computer system)). Subsequent to detecting that the user has resumed using the computer system (e.g.,900), the computer system (e.g.,900) detects a second position of the portion of the computer system (e.g.,900) relative to the portion of the body (e.g., a face, eyes, or wrist) of the user (e.g., relative to one or more features of a face of a user (e.g., relative to the eyes of the user and/or relative to the nose of the user)) (in some embodiments, the computer system is worn on the face of the user) (in some embodiments, detecting the position of the computer system relative to the face of the user is performed in response to detecting that the computer system is worn on the face of the user). In response to detecting the second position of the computer system (e.g.,900) relative to the portion of the body (e.g., a face, eyes, or wrist) of the user: in accordance with a determination that the second position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the first set of error conditions (e.g.,FIG.9E), the computer system (e.g.,900) displays, via the one or more display generation components, the first alert (e.g.,916); and in accordance with a determination that the second position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions (e.g.,FIG.9B), the computer system (e.g.,900) displays, via the one or more display generation components, the second alert (e.g.,914). In some embodiments, the first alert and/or the second alert are re-displayed when the user initiates a subsequent session (e.g., even if the user dismisses the first alert and/or the second alert in the previous session). Outputting a first alert or a second alert based on a determination that the position of the portion of the computer system relative to the body of the user meets one or more error conditions enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently. Furthermore, doing so also provides the user with visual feedback about a state of the device (e.g., the computer system has determined that the position of the computer system relative to the body of the user meets one or more error conditions). Providing such alerts can also improve user safety, by notifying the user of potential safety issues that could arise from the one or more error conditions. Providing a first alert that prevents access to one or more features of the computer system until the alert is dismissed also enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the computer system (e.g.,900) detects a third position of the portion of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user (e.g., relative to one or more features of a face of a user (e.g., relative to the eyes of the user and/or relative to the nose of the user)) (in some embodiments, the computer system is worn on the face of the user) (in some embodiments, detecting the position of the computer system relative to the face of the user is performed in response to detecting that the computer system is worn on the face of the user). In response to detecting the third position of the computer system (e.g.,900) relative to the portion of the body (e.g., a face, eyes, or wrist) of the user: in accordance with a determination that the third position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the first set of error conditions (e.g.,FIG.9E) and that the first set of error conditions has been met (e.g., has been continuously met, and/or has been met with less than a threshold amount of interruption) for greater than a threshold duration of time (e.g., greater than 0.25 seconds, greater than 0.5 seconds, or greater than 1 second), the computer system (e.g.,900) displays, via the one or more display generation components, the first alert (e.g.,916); and in accordance with a determination that the third position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the first set of error conditions and that the first set of error conditions has been met for less than the threshold duration of time (e.g., less than 0.25 seconds, less than 0.5 seconds, or less than 1 second), the computer system (e.g.,900) forgoes display of the first alert (e.g.,916) (e.g., forgoing display of the first alert until the first set of error conditions has been met for greater than the threshold duration of time). Delaying display of the first alert until the first set of error conditions has been met for greater than a threshold duration of time enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the computer system (e.g.,900) detects a fourth position of the portion of the computer system (e.g.,900) relative to the portion of the body (e.g., a face, eyes, or wrist) of the user (e.g., relative to one or more features of a face of a user (e.g., relative to the eyes of the user and/or relative to the nose of the user)) (in some embodiments, the computer system is worn on the face of the user) (in some embodiments, detecting the position of the computer system relative to the face of the user is performed in response to detecting that the computer system is worn on the face of the user). In response to detecting the fourth position of the computer system (e.g.,900) relative to the portion of the body (e.g., a face, eyes, or wrist) of the user: in accordance with a determination that the fourth position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions (e.g.,FIG.9B) and that the second set of error conditions has been met (e.g., has been continuously met, and/or has been met with less than a threshold amount of interruption) for greater than a second threshold duration of time (e.g., greater than 0.25 seconds, greater than 0.5 seconds, or greater than 1 second), the computer system (e.g.,900) displays, via the one or more display generation components, the second alert (e.g.,914); and in accordance with a determination that the fourth position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions and that the second set of error conditions has been met for less than the second threshold duration of time (e.g., less than 0.25 seconds, less than 0.5 seconds, or less than 1 second), the computer system (e.g.,900) forgoes display of the second alert (e.g.,914) (e.g., forgoing display of the second alert until the second set of error conditions has been met for greater than the second threshold duration of time). Delaying display of the second alert until the second set of error conditions has been met for greater than a threshold duration of time enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the computer system (e.g.,900) detects a fifth position of the portion of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user (e.g., relative to one or more features of a face of a user (e.g., relative to the eyes of the user and/or relative to the nose of the user)) (in some embodiments, the computer system is worn on the face of the user) (in some embodiments, detecting the position of the computer system relative to the face of the user is performed in response to detecting that the computer system is worn on the face of the user). In response to detecting the fifth position of the computer system (e.g.,900) relative to the portion of the body (e.g., a face, eyes, or wrist) of the user: in accordance with a determination that the fifth position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the first set of error conditions and that the computer system (e.g.,900) is operating in a first mode of operation (e.g., an authorized user mode of operation and/or a mode of operation indicative of the computer system being used by an authorized user, a known user, and/or a registered user) (e.g., an unrestricted mode of operation, an authorized user mode of operation, a known user mode of operation, and/or a recognized user mode of operation) that includes permitted access to a plurality of features (e.g.,FIG.9E) (e.g., a plurality of features associated with a logged in user experience and/or a plurality of features associated with an authorized user, a registered user, and/or a known user), the computer system (e.g.,900) displays, via the one or more display generation components, the first alert (e.g.,916); and in accordance with a determination that the fifth position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the first set of error conditions and that the computer system (e.g.,900) is operating in a guest mode of operation (e.g.,FIG.9G, as indicated by mode indication918) that has restricted access to one or more of the plurality of features (e.g., a guest mode of operation that has access to a subset of the plurality of features that are accessible in the first mode of operation, and/or a guest mode of operation that has access to fewer features than are available in the first mode of operation), the computer system (e.g.,900) displays, via the one or more display generation components, a third alert (e.g.,920) different from the first alert (e.g.,916). Displaying different alerts based on whether the computer system is operating in the first mode of operation or operating in the guest mode of operation enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the computer system (e.g.,900) detects a sixth position of the portion of the computer system relative to the portion of the body (e.g., a face, eyes, or wrist) of the user (e.g., relative to one or more features of a face of a user (e.g., relative to the eyes of the user and/or relative to the nose of the user)) (in some embodiments, the computer system is worn on the face of the user) (in some embodiments, detecting the position of the computer system relative to the face of the user is performed in response to detecting that the computer system is worn on the face of the user). In response to detecting the sixth position of the computer system (e.g.,900) relative to the portion of the body (e.g., a face, eyes, or wrist) of the user: in accordance with a determination that the sixth position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions (e.g.,FIG.9B) and that the computer system is operating in a first mode of operation (e.g., an authorized user mode of operation and/or a mode of operation indicative of the computer system being used by an authorized user, a known user, and/or a registered user) (e.g., an unrestricted mode of operation, an authorized user mode of operation, a known user mode of operation, and/or a recognized user mode of operation) that includes permitted access to a plurality of features (e.g., a plurality of features associated with a logged in user experience and/or a plurality of features associated with an authorized user, a registered user, and/or a known user), the computer system (e.g.,900) displays, via the one or more display generation components, the second alert (e.g.,914); and in accordance with a determination that the sixth position of the portion of the computer system (e.g.,900) relative to the portion of the body of the user meets the second set of error conditions and that the computer system (e.g.,900) is operating in a guest mode of operation (e.g.,FIG.9G, as indicated by mode indication918) that has restricted access to one or more of the plurality of features (e.g., a guest mode of operation that has access to a subset of the plurality of features that are accessible in the first mode of operation, and/or a guest mode of operation that has access to fewer features than are available in the first mode of operation), the computer system (e.g.,900) displays, via the one or more display generation components, a fourth alert (e.g.,920) different from the second alert. Displaying different alerts based on whether the computer system is operating in the first mode of operation or operating in the guest mode of operation enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the first alert (e.g.,916) prompts the user to change a light seal component (e.g.,1-110and/or1-210) (e.g., a physical component (e.g., a physical component that fits between the user's face and the computer system, a display device, and/or one or more display generation components) to block out light (e.g., prevent light (e.g., some light and/or all light) (e.g., external light and/or light that is not output by the computer system, a display device, and/or one or more display generation components) from reaching the eyes of the user) of the computer system (e.g.,900) that reduces an amount of external light that reaches the user's eyes while the display generation component is worn by the user (e.g., change the light seal component to a different light seal component that has different physical dimensions (e.g., a different depth and/or width; and/or a light seal that moves one or more components of the computer system closer to the eyes of the user and/or further from the eyes of the user) than a current light seal component). Prompting the user to change a light seal component of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.

In some embodiments, the second alert (e.g.,914) prompts the user to change a light seal component (e.g.,1-110and/or1-210) (e.g., a physical component (e.g., a physical component that fits between the user's face and the computer system, a display device, and/or one or more display generation components) to block out light (e.g., prevent light (e.g., some light and/or all light) (e.g., external light and/or light that is not output by the computer system, a display device, and/or one or more display generation components) from reaching the eyes of the user) of the computer system (e.g.,900) that reduces an amount of external light that reaches the user's eyes while the display generation component is worn by the user (e.g., change the light seal component to a different light seal component that has different physical dimensions (e.g., a different depth and/or width; and/or a light seal that moves one or more components of the computer system closer to the eyes of the user and/or further from the eyes of the user) than a current light seal component). Prompting the user to change a light seal component of the computer system enhances the operability of the system and makes the user-system interface more efficient (e.g., by helping the user to provide proper inputs and reducing errors) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the system more quickly and efficiently.
