[0001] This application claims priority to U.S. Patent Application No. 19 / 532,881, entitled “DEVICES, METHODS, AND GRAPHICAL USER INTERFACES FOR SCANNING PHYSICAL ENVIRONMENTS,” filed February 6, 2026, and to U.S.Provisional Patent Application No. 63 / 756,669, entitled “DEVICES, METHODS, AND GRAPHICAL USER INTERFACES FOR SCANNING PHYSICAL ENVIRONMENTS,” filed February 10, 2025. The contents of each of these applications are incorporated herein by reference in their entirety.TECHNICAL FIELD

[0002] The present disclosure relates generally to computer systems that are in communication with one or more output devices (e.g., optionally including one or more display generation components) and one or more sensors, including one or more optical sensors, and, optionally, one or more spatial information sensors, that provide computergenerated experiences, including, but not limited to, electronic devices that provide virtual reality and mixed reality experiences via a display.BACKGROUND

[0003] 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 touchscreen 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

[0004] Some methods and interfaces for interacting with a physical environment using a computer system are cumbersome, inefficient, and limited. For example, systems that provide insufficient feedback about the physical environment, systems that require a series of inputs to scan and / or interact with the physical environment, and systems in which scanning1010472 1Attorney Docket No. P69888W01 / 77770000840501the physical environment is 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.

[0005] Accordingly, there is a need for computer systems with improved methods and interfaces for interacting with a physical environment using a computer system 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 extended reality experiences to users. 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.

[0006] 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 (e.g., includes or is in communication with) a display generation component (e.g., a display device such as a head-mounted display (HMD), a display, a projector, a touch-sensitive display (also known as a “touch screen” or “touch-screen display”), or other device or component that presents visual content to a user, for example on or in the display generation component itself or produced from the display generation component and visible elsewhere). 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 performing1010472 2Attorney Docket No. P69888W01 / 77770000840501multiple 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.

[0007] There is a need for electronic devices with improved methods and interfaces for interacting with a three-dimensional environment. Such methods and interfaces may complement or replace conventional methods for interacting with a three-dimensional environment. 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. Such methods and interfaces reduce processing power, thereby reducing heat emitted by the computing devices, which is particularly important for wearable computing devices that can become uncomfortable for a user to wear if too much heat is produced, even when operating well within operational parameters for the device components.

[0050] The present disclosure relates to user interfaces for providing an extended reality (XR) experience to a user, in accordance with some embodiments.

[0051] The systems, methods, and GUIs described herein improve user interface interactions with a physical environment in multiple ways.1010472 15Attorney Docket No. P69888W01 / 77770000840501

[0052] In some embodiments, a computer system displays symbolic representations of objects detected (e.g., recognized) in a physical environment using one or more optical sensors. The symbolic representations of the detected objects are displayed without displaying another representation of the physical environment, such as a live- or near-live feed of a camera of the one or more optical sensors (e.g., a viewfinder). Displaying symbolic representations of objects detected in the physical environment allows the user to quickly review and interact with the computer system based on certain features detected in the environment without the distraction and / or visual clutter of a viewfinder. In addition, displaying symbolic representations of objects without a viewfinder allows scan results to be scaled to a variety of hardware, including computer systems with small displays and / or low-resolution optical sensors.

[0053] In some embodiments, while scanning a physical environment using one or more optical sensors, a computer system selectively provides scanning guidance for positioning the one or more optical sensors based on detection of a particular type of feature in the physical environment (e.g., a feature to be scanned). The scanning guidance prompts the user to change the position of the one or more optical sensors with respect to the detected feature in order to improve capture of the detected feature using the one or more optical sensors, allowing the computer system to provide scan results based on the optical sensor data. For example, the scanning guidance indicates to the user when the field-of-view of the optical sensors is misaligned with the feature to be scanned, when the optical sensors are too close to the feature to be scanned, and / or when the optical sensors are too far from the feature to be scanned. Selectively providing scanning guidance provides the user with feedback that assists the user with scanning the physical environment using the one or more optical sensors without cluttering a display with unnecessary visual outputs.

[0054] In some embodiments, a computer system provides different scan modes for scanning a physical environment using one or more optical sensors. Depending on the active scan mode, the computer system initiates different processes for providing scan results based on optical sensor data captured as the field-of-view of the one or more optical sensors moves with respect to the physical environment. For example, the different processes for providing scan results include providing the scan results in different conditions, generating different types of output, and / or generating different output content. Providing the different scan modes for scanning the physical environment provides users with more varied scan functionality without requiring numerous user inputs and / or displayed controls to access said1010472 16Attorney Docket No. P69888W01 / 77770000840501functionality, improving the user experience with scanning the physical environment using the one or more optical sensors.

[0055] In some embodiments, a computer system detects, using one or more spatial information sensors, the occurrence of an event, such as a current state and / or change to a state of the computer system’s location, position, and / or orientation within a physical environment. In response to the occurrence of an event, the computer system generates an alert. The alert includes different contents based on the detection of certain features in the physical environment using one or more optical sensors. Using a combination of spatial information sensor data and optical sensor data to generate alerts about the physical environment proactively provides users with useful, relevant, and / or desirable information and functionality without distracting the user with unnecessary, irrelevant, and / or unwanted alerts.

[0056] FIGS. 1 A-6 provide a description of example computer systems for providing XR experiences to users. FIGS. 7A-7Q illustrate example techniques for scanning a physical environment and providing scan results, in some embodiments. FIG. 8 is a flow diagram of methods of scanning a physical environment and providing scan results, in some embodiments. The user interfaces in FIGS. 7A-7Q are used to illustrate the processes in FIG.8. FIGS. 9A-9K illustrate example techniques for providing environment-aware guidance for scanning a physical environment, in some embodiments. FIG. 10 is a flow diagram of methods of providing environment-aware guidance for scanning a physical environment, in some embodiments. The user interfaces in FIGS. 9A-9K are used to illustrate the processes in FIG. 10. FIGS. 11A-1 IL illustrate example techniques for providing environment-aware guidance for scanning a physical environment, in some embodiments. FIG. 12 is a flow diagram of methods of providing feedback while scanning a physical environment in different scanning modes, in some embodiments. FIG. 13 is a flow diagram of methods of providing alerts based on different information detected while scanning a physical environment, in some embodiments. The user interfaces in FIGS. 11 A-l IL are used to illustrate the processes in FIGS. 12-13.

[0057] 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 1010472 17Attorney Docket No. P69888W01 / 77770000840501without 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.

[0058] In addition, in methods described herein where one or more steps are contingent upon one or more conditions having been met, it should be understood that the described method can be repeated in multiple repetitions so that over the course of the repetitions all of the conditions upon which steps in the method are contingent have been met in different repetitions of the method. For example, if a method requires performing a first step if a condition is satisfied, and a second step if the condition is not satisfied, then a person of ordinary skill would appreciate that the claimed steps are repeated until the condition has been both satisfied and not satisfied, in no particular order. Thus, a method described with one or more steps that are contingent upon one or more conditions having been met could be rewritten as a method that is repeated until each of the conditions described in the method has been met. This, however, is not required of system or computer readable medium claims where the system or computer readable medium contains instructions for performing the contingent operations based on the satisfaction of the corresponding one or more conditions and thus is capable of determining whether the contingency has or has not been satisfied without explicitly repeating steps of a method until all of the conditions upon which steps in the method are contingent have been met. A person having ordinary skill in the art would also understand that, similar to a method with contingent steps, a system or computer readable storage medium can repeat the steps of a method as many times as are needed to ensure that all of the contingent steps have been performed.

[0059] In some embodiments, as shown in FIG. 1 A, the XR experience is provided to the user via an operating environment 100 that includes a computer system 101. The computer1010472 18Attorney Docket No. P69888W01 / 77770000840501system 101 includes a controller 110 (e.g., processors of a portable electronic device or a remote server), a display generation component 120 (e.g., a head-mounted display (HMD), a display, a projector, a touch-screen, etc.), one or more input devices 125 (e.g., an eye tracking device 130, a hand tracking device 140, other input devices 150), one or more output devices 155 (e.g., speakers 160, tactile output generators 170, and other output devices 180), one or more sensors 190 (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 devices 195 (e.g., home appliances, wearable devices, etc.). In some embodiments, one or more of the input devices 125, output devices 155, sensors 190, and peripheral devices 195 are integrated with the display generation component 120 (e.g., in a head-mounted device or a handheld device).

[0060] When describing an 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 system 101 generating 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 system 101). The following is a subset of these terms:

[0061] Physical environment: A physical environment refers to a physical world that people can sense and / or interact with without aid of electronic systems. Physical environments, such as a physical park, include physical articles, such as physical trees, physical buildings, and physical people. People can directly sense and / or interact with the physical environment, such as through sight, touch, hearing, taste, and smell.

[0062] 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 1010472 19Attorney Docket No. P69888W01 / 77770000840501senses, 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.

[0063] Examples of XR include virtual reality and mixed reality.

[0064] Virtual reality: A virtual reality (VR) environment refers to a simulated environment that is designed to be based entirely on computer-generated sensory inputs for one or more senses. A VR environment comprises a plurality of virtual objects with which a person may sense and / or interact. For example, computer-generated imagery of trees, buildings, and avatars representing people are examples of virtual objects. A person may sense and / or interact with virtual objects in the VR environment through a simulation of the person’s presence within the computer-generated environment, and / or through a simulation of a subset of the person’s physical movements within the computer-generated environment.

[0065] 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.

[0066] Examples of mixed realities include augmented reality and augmented virtuality.

[0067] 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 an1010472 20Attorney Docket No. P69888W01 / 77770000840501AR 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.

[0068] Augmented virtuality: An augmented virtuality (AV) environment refers to a simulated environment in which a virtual or computer-generated environment incorporates one or more sensory inputs from the physical environment. The sensory inputs may be representations of one or more characteristics of the physical environment. For example, an AV park may have virtual trees and virtual buildings, but people with faces photorealistically reproduced from images taken of physical people. As another example, a virtual object may adopt a shape or color of a physical article imaged by one or more imaging sensors. As a1010472 21Attorney Docket No. P69888W01 / 77770000840501further example, a virtual object may adopt shadows consistent with the position of the sun in the physical environment.

[0069] 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 and 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 the1010472 22Attorney Docket No. P69888W01 / 77770000840501display 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).

[0070] 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 the1010472 23Attorney Docket No. P69888W01 / 77770000840501virtual 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, 1010472 24Attorney Docket No. P69888W01 / 77770000840501and / 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.

[0071] 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.”

[0072] 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-dimensional1010472 25Attorney Docket No. P69888W01 / 77770000840501environment (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.

[0073] 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 5-300cm 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 moving1010472 26Attorney Docket No. P69888W01 / 77770000840501or 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, or 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).

[0074] Hardware: There are many different types of electronic systems that enable a person to sense and / or interact with various XR environments. Examples include headmounted 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 system1010472 27Attorney Docket No. P69888W01 / 77770000840501may be configured to accept an external opaque display (e.g., a smartphone). The headmounted 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 controller 110 is configured to manage and coordinate a XR experience for the user. In some embodiments, the controller 110 includes a suitable combination of software, firmware, and / or hardware. The controller 110 is described in greater detail below with respect to FIG. 2. In some embodiments, the controller 110 is a computing device that is local or remote relative to the scene 105 (e.g., a physical environment). For example, the controller 110 is a local server located within the scene 105. In another example, the controller 110 is a remote server located outside of the scene 105 (e.g., a cloud server, central server, etc.). In some embodiments, the controller 110 is communicatively coupled with the display generation component 120 (e.g., an HMD, a display, a projector, a touchscreen, etc.) via one or more wired or wireless communication channels 144 (e.g., BLUETOOTH, IEEE 802.1 lx, IEEE 802.16x, IEEE 802.3x, etc.). In another example, the controller 110 is included within the enclosure (e.g., a physical housing) of the display generation component 120 (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 devices 125, one or more of the output devices 155, one or more of the sensors 190, and / or one or more of the peripheral devices 195, or share the same physical enclosure or support structure with one or more of the above.

[0075] In some embodiments, the display generation component 120 is 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 component 120 includes a suitable combination1010472 28Attorney Docket No. P69888W01 / 77770000840501of software, firmware, and / or hardware. The display generation component 120 is described in greater detail below with respect to FIG. 3 A. In some embodiments, the functionalities of the controller 110 are provided by and / or combined with the display generation component 120.

[0076] According to some embodiments, the display generation component 120 provides an XR experience to the user while the user is virtually and / or physically present within the scene 105.

[0077] 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 component 120 includes one or more XR displays provided to display the XR content. For example, in various embodiments, the display generation component 120 encloses the field-of-view of the user. In some embodiments, the display generation component 120 is a handheld device (such as a smartphone or tablet) configured to present XR content, and the user holds the device with a display directed towards the field-of-view of the user and a camera directed towards the scene 105. 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 component 120 is a XR chamber, enclosure, or room configured to present XR content in which the user does not wear or hold the display generation component 120. Many user interfaces described with reference to one type of hardware for displaying XR content (e.g., a handheld device or a device on a tripod) 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 scene 105 or 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 scene 105 or a part of the user’s body (e.g., the user’s eye(s), head, or hand)).1010472 29Attorney Docket No. P69888W01 / 77770000840501

[0078] While pertinent features of the operating environment 100 are shown in FIG. 1 A, 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.

[0079] FIGS. 1 A-1P illustrate 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 assemblies l-120a, l-120b and / or first and second optical modules 11.1. l-104a and 11.1. l-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 lenses 11.3.2-216 that 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 assemblies 1-120a, l-120b and / or first and second optical modules ll.l.l-104a and 11.1. l-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 assembly 1-108) 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 component 1-112) 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 assembly 1-356, and / or FIG. II) for detecting information about a physical environment of the device which can be used (optionally in conjunction with one or more illuminators such as the1010472 30Attorney Docket No. P69888W01 / 77770000840501illuminators described in FIG. II) 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 assembly 1-356, and / or FIG. II) that can be used (optionally in conjunction with one or more illuminators such as the illuminators 6-124 described in FIG. II) 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 in FIG. II) which can be used (optionally in conjunction with one or more lights such as lights 11.3.2-110 in FIG. 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 button 1-128, button 11.1.1-114 , second button 1-132, and or dial or button 1-328), knobs (e.g., first button 1-128, button 11.1.1-114, and / or dial or button 1-328), digital crowns (e.g., first button 1-128 which is depressible and twistable or rotatable, button 11.1.1-114, and / or dial or button 1-328), trackpads, touch screens, keyboards, mice and / or other input devices. One or more buttons (e.g., first button 1-128, button 11.1.1-114, second button 1-132, and or dial or button 1-328) are optionally used to perform system operations such as 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 button 1-128 which is depressible and twistable or rotatable, button 11.1.1-114, and / or dial or button 1-328) are optionally rotatable to adjust 1010472 31Attorney Docket No. P69888W01 / 77770000840501parameters 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 assemblies l-120a, l-120b and / or first and second optical modules 11.1.1-104a and 11.1. l-104b).

[0080] FIG. IB illustrates a front, top, perspective view of an example of a head-mountable display (HMD) device 1-100 configured to be donned by a user and provide virtual and altered / mixed reality (VR / AR) experiences. The HMD 1-100 can include a display unit 1-102 or assembly, an electronic strap assembly 1-104 connected to and extending from the display unit 1-102, and a band assembly 1-106 secured at either end to the electronic strap assembly 1-104. The electronic strap assembly 1-104 and the band 1-106 can be part of a retention assembly configured to wrap around a user’s head to hold the display unit 1-102 against the face of the user.

[0081] In at least one example, the band assembly 1-106 can include a first band 1-116 configured to wrap around the rear side of a user’s head and a second band 1-117 configured to extend over the top of a user’s head. The second strap can extend between first and second electronic straps l-105a, 1 -105b of the electronic strap assembly 1-104 as shown. The strap assembly 1-104 and the band assembly 1-106 can be part of a securement mechanism extending rearward from the display unit 1-102 and configured to hold the display unit 1-102 against a face of a user.

[0082] In at least one example, the securement mechanism includes a first electronic strap l-105a including a first proximal end 1-134 coupled to the display unit 1-102, for example a housing 1-150 of the display unit 1-102, and a first distal end 1-136 opposite the first proximal end 1-134.

[0120] FIG. 1 J illustrates a lower perspective view of an example of an HMD 6-200 including a cover or shroud 6-204 secured to a frame 6-230. In at least one example, the sensors 6-203 of the sensor system 6-202 can be disposed around a perimeter of the HDM 6-200 such that the sensors 6-203 are outwardly disposed around a perimeter of a display region or area 6-232 so as not to obstruct a view of the displayed light. In at least one example, the sensors can be disposed behind the shroud 6-204 and aligned with transparent portions of the shroud allowing sensors and projectors to allow light back and forth through the shroud 6-204. In at least one example, opaque ink or other opaque material or films / layers can be disposed on the shroud 6-204 around the display area 6-232 to hide components of the HMD 6-200 outside the display area 6-232 other than the transparent portions defined by the opaque portions, through which the sensors and projectors send and receive light and electromagnetic signals during operation. In at least one example, the shroud 6-204 allows light to pass therethrough from the display (e.g., within the display region 6-232) but not radially outward from the display region around the perimeter of the display and shroud 6-204.1010472 42Attorney Docket No. P69888W01 / 77770000840501

[0121] In some examples, the shroud 6-204 includes a transparent portion 6-205 and an opaque portion 6-207, as described above and elsewhere herein. In at least one example, the opaque portion 6-207 of the shroud 6-204 can define one or more transparent regions 6-209 through which the sensors 6-203 of the sensor system 6-202 can send and receive signals. In the illustrated example, the sensors 6-203 of the sensor system 6-202 sending and receiving signals through the shroud 6-204, or more specifically through the transparent regions 6-209 of the (or defined by) the opaque portion 6-207 of the shroud 6-204 can include the same or similar sensors as those shown in the example of FIG.

For example, the shroud 6-204 shown in FIG. 1J includes the opaque portion 6-207 that would visually cover / block a view of anything outside (e.g., radially / peripherally outside) the di splay / di splay region 6-334, including the sensors 6-303 and bracket 6-338.

[0124] In at least one example, the various sensors of the sensor system 6-302 are coupled to the brackets 6-336, 6-338. In at least one example, the scene cameras 6-306 include tight tolerances of angles relative to one another. For example, the tolerance of mounting angles between the two scene cameras 6-306 can be 0.5 degrees or less, for example 0.3 degrees or less. In order to achieve and maintain such a tight tolerance, in one example, the scene cameras 6-306 can be mounted to the bracket 6-338 and not the shroud. 1010472 43Attorney Docket No. P69888W01 / 77770000840501The bracket can include cantilevered arms on which the scene cameras 6-306 and other sensors of the sensor system 6-302 can be mounted to remain un-deformed in position and orientation in the case of a drop event by a user resulting in any deformation of the other bracket 6-226, housing 6-330, and / or shroud.

[0125] Any of the features, components, and / or parts, including the arrangements and configurations thereof shown in FIG.

[0128] FIG. IM illustrates a rear perspective view of an inter-pupillary distance (IPD) adjustment system 11.1.1-102 including first and second optical modules 11.1. l-104a-b slidably engaging / coupled to respective guide-rods 11.1. l-108a-b and motors 11.1.1-1 lOa-b of left and right adjustment subsystems 11.1. l-106a-b. The IPD adjustment system 11.1.1-102 can be coupled to a bracket 11.1.1-112 and include a button 11.1.1-114 in electrical1010472 44Attorney Docket No. P69888W01 / 77770000840501communication with the motors 11.1.1-1 lOa-b. In at least one example, the button 11.1.1-114 can electrically communicate with the first and second motors 11.1.1-1 lOa-b via a processor or other circuitry components to cause the first and second motors 11.1.1-1 lOa-b to activate and cause the first and second optical modules 11.1. l-104a-b, respectively, to change position relative to one another.

[0129] In at least one example, the first and second optical modules 11.1.1-104a-b can include respective display screens configured to project light toward the user’s eyes when donning the HMD 11.1.1-100. In at least one example, the user can manipulate (e.g., depress and / or rotate) the button 11.1.1-114 to activate a positional adjustment of the optical modules 11.1. l-104a-b to match the inter-pupillary distance of the user’s eyes. The optical modules 11.1. l-104a-b can also include one or more cameras or other sensors / sensor systems for imaging and measuring the IPD of the user such that the optical modules 11.1. l-104a-b can be adjusted to match the IPD.

[0130] In one example, the user can manipulate the button 11.1.1-114 to cause an automatic positional adjustment of the first and second optical modules 11.1. l-104a-b. In one example, the user can manipulate the button 11.1.1-114 to cause a manual adjustment such that the optical modules 11.1. l-104a-b move further or closer away, for example when the user rotates the button 11.1.1-114 one way or the other, until the user visually matches her / his own IPD. In one example, the manual adjustment is electronically communicated via one or more circuits and power for the movements of the optical modules 11.1. l-104a-b via the motors 11.1.1-1 lOa-b is provided by an electrical power source. In one example, the adjustment and movement of the optical modules 11.1. l-104a-b via a manipulation of the button 11.1.1-114 is mechanically actuated via the movement of the button 11.1.1-114.

[0131] Any of the features, components, and / or parts, including the arrangements and configurations thereof shown in FIG.

[0132] FIG. IN illustrates a front perspective view of a portion of an HMD 11.1.2-100, including an outer structural frame 11.1.2-102 and an inner or intermediate structural frame1010472 45Attorney Docket No. P69888W01 / 7777000084050111.1.2-104 defining first and second apertures 11.1.2- 106a, 11.1.2- 106b. The apertures 11.1.2-106a-b are shown in dotted lines in FIG. IN because a view of the apertures 11.1.2-106a-b can be blocked by one or more other components of the HMD 11.1.2-100 coupled to the inner frame 11.1.2-104 and / or the outer frame 11.1.2-102, as shown. In at least one example, the HMD 11.1.2-100 can include a first mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104. In at least one example, the mounting bracket 11.1.2-108 is coupled to the inner frame 11.1.2-104 between the first and second apertures 11.1 ,2-106a-b.

[0133] The mounting bracket 11.1.2-108 can include a middle or central portion 11.1.2-109 coupled to the inner frame 11.1.2-104. In some examples, the middle or central portion 11.1.2-109 may not be the geometric middle or center of the bracket 11.1.2-108. Rather, the middle / central portion 11.1.2-109 can be disposed between first and second cantilevered extension arms extending away from the middle portion 11.1.2-109. In at least one example, the mounting bracket 108 includes a first cantilever arm 11.1.2-112 and a second cantilever arm 11.1.2-114 extending away from the middle portion 11.1.2-109 of the mount bracket 11.1.2-108 coupled to the inner frame 11.1.2-104.

[0134] As shown in FIG. IN, the outer frame 11.1.2-102 can define a curved geometry on a lower side thereof to accommodate a user’s nose when the user dons the HMD 11.1.2-100. The curved geometry can be referred to as a nose bridge 11.1.2-111 and be centrally located on a lower side of the HMD 11.1.2-100 as shown. In at least one example, the mounting bracket 11.1.2-108 can be connected to the inner frame 11.1.2-104 between the apertures 11.1.2-106a-b such that the cantilevered arms 11.1.2-112, 11.1.2-114 extend downward and laterally outward away from the middle portion 11.1.2-109 to compliment the nose bridge 11.1.2-111 geometry of the outer frame 11.1.2-102. In this way, the mounting bracket 11.1.2-108 is configured to accommodate the user’s nose as noted above. The nose bridge 11.1.2-111 geometry accommodates the nose in that the nose bridge 11.1.2-111 provides a curvature that curves with, above, over, and around the user’s nose for comfort and fit.

[0135] The first cantilever arm 11.1.2-112 can extend away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-108 in a first direction and the second cantilever arm 11.1.2-114 can extend away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-10 in a second direction opposite the first direction. The first and second cantilever arms 11.1.2-112, 11.1.2-114 are referred to as “cantilevered” or “cantilever” arms because each arm 11.1.2-112, 11.1.2-114, includes a distal free end 11.1.2-116, 11.1.2-118, respectively, which are free of affixation from the inner and outer frames 11.1.2-102, 11.1.2- 1010472 46Attorney Docket No. P69888W01 / 77770000840501104. In this way, the arms 11.1.2-112, 11.1.2-114 are cantilevered from the middle portion 11.1.2-109, which can be connected to the inner frame 11.1.2-104, with distal ends 11.1.2-102, 11.1.2-104 unattached.

[0136] In at least one example, the HMD 11.1.2-100 can include one or more components coupled to the mounting bracket 11.1.2-108. In one example, the components include a plurality of sensors 11.1.2-1 lOa-f. Each sensor of the plurality of sensors 11.1.2-1 lOa-f can include various types of sensors, including cameras, IR sensors, and so forth. In some examples, one or more of the sensors 11.1.2-1 lOa-f can 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 sensors 11.1.2-1 lOa-f. The cantilevered nature of the mounting bracket 11.1.2-108 can protect the sensors 11.1.2-1 lOa-f from damage and altered positioning in the case of accidental drops by the user. Because the sensors 11.1.2-1 lOa-f are cantilevered on the arms 11.1.2-112, 11.1.2-114 of the mounting bracket 11.1.2-108, stresses and deformations of the inner and / or outer frames 11.1.2-104, 11.1.2-102 are not transferred to the cantilevered arms 11.1.2-112, 11.1.2-114 and thus do not affect the relative positioning of the sensors 11.1.2-1 lOa-f coupled / mounted to the mounting bracket 11.1.2-108.

Application 3160 includes application implementation module 3170 and API-calling module 3180. System 3110 includes API 3190 and implementation module 3100. It should be recognized that device1010472 57Attorney Docket No. P69888W01 / 777700008405013150, application 3160, and / or system 3110 can include more, fewer, and / or different components than illustrated in FIGS. 3D and 3E.

[0179] In some embodiments, application implementation module 3170 includes a set of one or more instructions corresponding to one or more operations performed by application 3160. For example, when application 3160 is a messaging application, application implementation module 3170 can include operations to receive and send messages. In some embodiments, application implementation module 3170 communicates with API-calling module 3180 to communicate with system 3110 via API 3190 (shown in FIG. 3E).

[0180] In some embodiments, API 3190 is a software module (e.g., a collection of computer-readable instructions) that provides an interface that allows a different module (e.g., API-calling module 3180) to access and / or use one or more functions, methods, procedures, data structures, classes, and / or other services provided by implementation module 3100 of system 3110. For example, API-calling module 3180 can access a feature of implementation module 3100 through one or more API calls or invocations (e.g., embodied by a function or a method call) exposed by API 3190 (e.g., a software and / or hardware module that can receive API calls, respond to API calls, and / or send API calls) and can pass data and / or control information using one or more parameters via the API calls or invocations. In some embodiments, API 3190 allows application 3160 to use a service provided by a Software Development Kit (SDK) library. In some embodiments, application 3160 incorporates a call to a function or method provided by the SDK library and provided by API 3190 or uses data types or objects defined in the SDK library and provided by API 3190. In some embodiments, API-calling module 3180 makes an API call via API 3190 to access and use a feature of implementation module 3100 that is specified by API 3190. In such embodiments, implementation module 3100 can return a value via API 3190 to API-calling module 3180 in response to the API call. The value can report to application 3160 the capabilities or state of a hardware component of device 3150, including those related to aspects such as input capabilities and state, output capabilities and state, processing capability, power state, storage capacity and state, and / or communications capability. In some embodiments, API 3190 is implemented in part by firmware, microcode, or other low level logic that executes in part on the hardware component.

[0181] In some embodiments, API 3190 allows a developer of API-calling module 3180 (which can be a third-party developer) to leverage a feature provided by implementation module 3100. In such embodiments, there can be one or more API-calling modules (e.g., 1010472 58Attorney Docket No. P69888W01 / 77770000840501including API-calling module 3180) that communicate with implementation module 3100. In some embodiments, API 3190 allows multiple API-calling modules written in different programming languages to communicate with implementation module 3100 (e.g., API 3190 can include features for translating calls and returns between implementation module 3100 and API-calling module 3180) while API 3190 is implemented in terms of a specific programming language. In some embodiments, API-calling module 3180 calls APIs from different providers such as a set of APIs from an OS provider, another set of APIs from a plug-in provider, and / or another set of APIs from another provider (e.g., the provider of a software library) or creator of the another set of APIs.

[0182] Examples of API 3190 can include one or more of: a pairing API (e.g., for establishing secure connection, e.g., with an accessory), a device detection API (e.g., for locating nearby devices, e.g., media devices and / or smartphone), a payment API, a UIKit API (e.g., for generating user interfaces), a location detection API, a locator API, a maps API, a health sensor API, a sensor API, a messaging API, a push notification API, a streaming API, a collaboration API, a video conferencing API, an application store API, an advertising services API, a web browser API (e.g., WebKit API), a vehicle API, a networking API, a WiFi API, a Bluetooth API, an NFC API, a UWB API, a fitness API, a smart home API, contact transfer API, photos API, camera API, and / or image processing API. In some embodiments, the sensor API is an API for accessing data associated with a sensor of device 3150. For example, the sensor API can provide access to raw sensor data. For another example, the sensor API can provide data derived (and / or generated) from the raw sensor data. In some embodiments, the sensor data includes temperature data, image data, video data, audio data, heart rate data, IMU (inertial measurement unit) data, lidar data, location data, GPS data, and / or camera data. In some embodiments, the sensor includes one or more of an accelerometer, temperature sensor, infrared sensor, optical sensor, heartrate sensor, barometer, gyroscope, proximity sensor, temperature sensor, and / or biometric sensor.

[0183] In some embodiments, implementation module 3100 is a system (e.g., operating system and / or server system) software module (e.g., a collection of computer-readable instructions) that is constructed to perform an operation in response to receiving an API call via API 3190. In some embodiments, implementation module 3100 is constructed to provide an API response (via API 3190) as a result of processing an API call. By way of example, implementation module 3100 and API-calling module 3180 can each be any one of an operating system, a library, a device driver, an API, an application program, or other module.1010472 59Attorney Docket No. P69888W01 / 77770000840501It should be understood that implementation module 3100 and API-calling module 3180 can be the same or different type of module from each other. In some embodiments, implementation module 3100 is embodied at least in part in firmware, microcode, or hardware logic.

[0184] In some embodiments, implementation module 3100 returns a value through API 3190 in response to an API call from API-calling module 3180. While API 3190 defines the syntax and result of an API call (e.g., how to invoke the API call and what the API call does), API 3190 might not reveal how implementation module 3100 accomplishes the function specified by the API call. Various API calls are transferred via the one or more application programming interfaces between API-calling module 3180 and implementation module 3100. Transferring the API calls can include issuing, initiating, invoking, calling, receiving, returning, and / or responding to the function calls or messages. In other words, transferring can describe actions by either of API-calling module 3180 or implementation module 3100. In some embodiments, a function call or other invocation of API 3190 sends and / or receives one or more parameters through a parameter list or other structure.

[0185] In some embodiments, implementation module 3100 provides more than one API, each providing a different view of or with different aspects of functionality implemented by implementation module 3100. For example, one API of implementation module 3100 can provide a first set of functions and can be exposed to third-party developers, and another API of implementation module 3100 can be hidden (e.g., not exposed) and provide a subset of the first set of functions and also provide another set of functions, such as testing or debugging functions which are not in the first set of functions. In some embodiments, implementation module 3100 calls one or more other components via an underlying API and thus is both an API-calling module and an implementation module. It should be recognized that implementation module 3100 can include additional functions, methods, classes, data structures, and / or other features that are not specified through API 3190 and are not available to API-calling module 3180. It should also be recognized that API-calling module 3180 can be on the same system as implementation module 3100 or can be located remotely and access implementation module 3100 using API 3190 over a network. In some embodiments, implementation module 3100, API 3190, and / or API-calling module 3180 is stored in a machine-readable medium, which includes any mechanism for storing information in a form readable by a machine (e.g., a computer or other data processing system). For example, a1010472 60Attorney Docket No. P69888W01 / 77770000840501machine-readable medium can include magnetic disks, optical disks, random access memory; read only memory, and / or flash memory devices.

[0186] An application programming interface (API) is an interface between a first software process and a second software process that specifies a format for communication between the first software process and the second software process. Limited APIs (e.g., private APIs or partner APIs) are APIs that are accessible to a limited set of software processes (e.g., only software processes within an operating system or only software processes that are approved to access the limited APIs). Public APIs that are accessible to a wider set of software processes. Some APIs enable software processes to communicate about or set a state of one or more input devices (e.g., one or more touch sensors, proximity sensors, visual sensors, motion / orientation sensors, pressure sensors, intensity sensors, sound sensors, wireless proximity sensors, biometric sensors, buttons, switches, rotatable elements, and / or external controllers). Some APIs enable software processes to communicate about and / or set a state of one or more output generation components (e.g., one or more audio output generation components, one or more display generation components, and / or one or more tactile output generation components). Some APIs enable particular capabilities (e.g., scrolling, handwriting, text entry, image editing, and / or image creation) to be accessed, performed, and / or used by a software process (e.g., generating outputs for use by a software process based on input from the software process). Some APIs enable content from a software process to be inserted into a template and displayed in a user interface that has a layout and / or behaviors that are specified by the template.

[0187] Many software platforms include a set of frameworks that provides the core objects and core behaviors that a software developer needs to build software applications that can be used on the software platform. Software developers use these objects to display content onscreen, to interact with that content, and to manage interactions with the software platform. Software applications rely on the set of frameworks for their basic behavior, and the set of frameworks provides many ways for the software developer to customize the behavior of the application to match the specific needs of the software application. Many of these core objects and core behaviors are accessed via an API. An API will typically specify a format for communication between software processes, including specifying and grouping available variables, functions, and protocols. An API call (sometimes referred to as an API request) will typically be sent from a sending software process to a receiving software process as a way to accomplish one or more of the following: the sending software process1010472 61Attorney Docket No. P69888W01 / 77770000840501requesting information from the receiving software process (e.g., for the sending software process to take action on), the sending software process providing information to the receiving software process (e.g., for the receiving software process to take action on), the sending software process requesting action by the receiving software process, or the sending software process providing information to the receiving software process about action taken by the sending software process. Interaction with a device (e.g., using a user interface) will in some circumstances include the transfer and / or receipt of one or more API calls (e.g., multiple API calls) between multiple different software processes (e.g., different portions of an operating system, an application and an operating system, or different applications) via one or more APIs (e.g., via multiple different APIs). For example, when an input is detected the direct sensor data is frequently processed into one or more input events that are provided (e.g., via an API) to a receiving software process that makes some determination based on the input events, and then sends (e.g., via an API) information to a software process to perform an operation (e.g., change a device state and / or user interface) based on the determination. While a determination and an operation performed in response could be made by the same software process, alternatively the determination could be made in a first software process and relayed (e.g., via an API) to a second software process, that is different from the first software process, that causes the operation to be performed by the second software process. Alternatively, the second software process could relay instructions (e.g., via an API) to a third software process that is different from the first software process and / or the second software process to perform the operation. It should be understood that some or all user interactions with a computer system could involve one or more API calls within a step of interacting with the computer system (e.g., between different software components of the computer system or between a software component of the computer system and a software component of one or more remote computer systems). It should be understood that some or all user interactions with a computer system could involve one or more API calls between steps of interacting with the computer system (e.g., between different software components of the computer system or between a software component of the computer system and a software component of one or more remote computer systems).

[0188] In some embodiments, the application can be any suitable type of application, including, for example, one or more of: a browser application, an application that functions as an execution environment for plug-ins, widgets or other applications, a fitness application, a1010472 62Attorney Docket No. P69888W01 / 77770000840501health application, a digital payments application, a media application, a social network application, a messaging application, and / or a maps application.

[0189] In some embodiments, the application is an application that is pre-installed on the first computer system at purchase (e.g., a first-party application). In some embodiments, the application is an application that is provided to the first computer system via an operating system update file (e.g., a first-party application). In some embodiments, the application is an application that is provided via an application store. In some embodiments, the application store is pre-installed on the first computer system at purchase (e.g., a first-party application store) and allows download of one or more applications. In some embodiments, the application store is a third-party application store (e.g., an application store that is provided by another device, downloaded via a network, and / or read from a storage device). In some embodiments, the application is a third-party application (e.g., an app that is provided by an application store, downloaded via a network, and / or read from a storage device). In some embodiments, the application controls the first computer system to perform methods 800, 1000, 1200, and / or 1300 (FIGS. 8, 10, 12, and / or 13) by calling an application programming interface (API) provided by the system process using one or more parameters.

[0190] In some embodiments, exemplary APIs provided by the system process include one or more of a pairing API (e.g., for establishing secure connection, e.g., with an accessory), a device detection API (e.g., for locating nearby devices, e.g., media devices and / or smartphone), a payment API, a UIKit API (e.g., for generating user interfaces), a location detection API, a locator API, a maps API, a health sensor API, a sensor API, a messaging API, a push notification API, a streaming API, a collaboration API, a video conferencing API, an application store API, an advertising services API, a web browser API (e.g., WebKit API), a vehicle API, a networking API, a WiFi API, a Bluetooth API, an NFC API, a UWB API, a fitness API, a smart home API, contact transfer API, a photos API, a camera API, and / or an image processing API.

[0191] In some embodiments, at least one API is a software module (e.g., a collection of computer-readable instructions) that provides an interface that allows a different module (e.g., API-calling module 3180) to access and use one or more functions, methods, procedures, data structures, classes, and / or other services provided by an implementation module of the system process. The API can define one or more parameters that are passed between the API-calling module and the implementation module. In some embodiments, API 3190 defines a first API call that can be provided by API-calling module 3180. The 1010472 63Attorney Docket No. P69888W01 / 77770000840501implementation module is a system software module (e.g., a collection of computer-readable instructions) that is constructed to perform an operation in response to receiving an API call via the API. In some embodiments, the implementation module is constructed to provide an API response (via the API) as a result of processing an API call. In some embodiments, the implementation module is included in the device (e.g., 3150) that runs the application. In some embodiments, the implementation module is included in an electronic device that is separate from the device that runs the application.

[0192] FIG. 4 is a schematic, pictorial illustration of an example embodiment of the hand tracking device 140. In some embodiments, hand tracking device 140 (FIG. 1 A) is controlled by hand tracking unit 244 (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 scene 105 of FIG. 1 A (e.g., with respect to a portion of the physical environment surrounding the user, with respect to the display generation component 120, 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 device 140 is part of the display generation component 120 (e.g., embedded in or attached to a headmounted device). In some embodiments, the hand tracking device 140 is separate from the display generation component 120 (e.g., located in separate housings or attached to separate physical support structures).

[0193] In some embodiments, the hand tracking device 140 includes image sensors 404 (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 hand 406 of a human user. The image sensors 404 capture the hand images with sufficient resolution to enable the fingers and their respective positions to be distinguished. The image sensors 404 typically 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 sensors 404 also capture 2D color video images of the hand 406 and other elements of the scene. In some embodiments, the image sensors 404 are used in conjunction with other image sensors to capture the physical environment of the scene 105 or serve as the image sensors that capture the physical environments of the scene 105. In some embodiments, the image sensors 404 are positioned relative to the user or the user’s environment in a way that a field of view of1010472 64Attorney Docket No. P69888W01 / 77770000840501the 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 controller 110.

[0194] In some embodiments, the image sensors 404 output a sequence of frames containing 3D map data (and possibly color image data, as well) to the controller 110, 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 component 120 accordingly. For example, the user may interact with software running on the controller 110 by moving his hand 406 and changing his hand posture.

[0195] In some embodiments, the image sensors 404 project a pattern of spots onto a scene containing the hand 406 and capture an image of the projected pattern. In some embodiments, the controller 110 computes 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 sensors 404. In the present disclosure, the image sensors 404 are 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 sensors 404 (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.

[0196] In some embodiments, the hand tracking device 140 captures 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 sensors 404 and / or the controller 110 processes the 3D map data to extract patch descriptors of the hand in these depth maps. The software matches these descriptors to patch descriptors stored in a database 408, 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 fingertips.

[0197] 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 functions1010472 65Attorney Docket No. P69888W01 / 77770000840501described 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 controller 110. This program may, for example, move and modify images presented on the display generation component 120, or perform other functions, in response to the pose and / or gesture information.

[0198] 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 system 101, one or more input device 125, and / or hand tracking device 140) 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).

[0199] 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 accordance with 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 a1010472 66Attorney Docket No. P69888W01 / 77770000840501hand 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).

[0200] 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.

[0201] 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 accordance with 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).1010472 67Attorney Docket No. P69888W01 / 77770000840501

[0202] 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 accordance with some embodiments. For example, the pinch inputs and tap inputs described below are performed as air gestures.

[0203] 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.

[0204] In some embodiments, a pinch and drag gesture that is an air gesture (e.g., an air drag gesture or an air swipe gesture) includes a pinch gesture (e.g., a pinch gesture or a long pinch gesture) performed in conjunction with (e.g., 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 second1010472 68Attorney Docket No. P69888W01 / 77770000840501hand 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).

[0205] 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).

[0206] 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 threshold1010472 69Attorney Docket No. P69888W01 / 77770000840501from 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).

[0207] 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 50cm), 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.

[0208] 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 or1010472 70Attorney Docket No. P69888W01 / 77770000840501change 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, where 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 (e.g., an air drag gesture or an air swipe gesture) 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.

[0209] In some embodiments, the software may be downloaded to the controller 110 in 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 database 408 is likewise stored in a memory associated with the controller 110. Alternatively or additionally, some or all of the described functions of the computer may be implemented in dedicated hardware, such as a custom or semi-custom integrated circuit or a programmable digital signal processor (DSP). Although the controller 110 is shown in FIG. 4, by way of example, as a separate unit from the image sensors 404, 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 sensors 404 (e.g., a hand tracking device) or otherwise associated with the image sensors 404. 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 component 120 (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 functions1010472 71Attorney Docket No. P69888W01 / 77770000840501of image sensors 404 may likewise be integrated into the computer or other computerized apparatus that is to be controlled by the sensor output.

[0210] FIG. 4 further includes a schematic representation of a depth map 410 captured by the image sensors 404, in accordance with some embodiments. The depth map, as explained above, comprises a matrix of pixels having respective depth values. The pixels 412 corresponding to the hand 406 have been segmented out from the background and the wrist in this map. The brightness of each pixel within the depth map 410 corresponds inversely to its depth value, e.g., the measured z distance from the image sensors 404, with the shade of gray growing darker with increasing depth. The controller 110 processes these depth values in order to identify and segment a component of the image (e.g., 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.

[0211] FIG. 4 also schematically illustrates a hand skeleton 414 that controller 110 ultimately extracts from the depth map 410 of the hand 406, in accordance with some embodiments. In FIG. 4, the hand skeleton 414 is superimposed on a hand background 416 that has been segmented from the original depth map. In some embodiments, key feature points of the hand (e.g., points corresponding to knuckles, fingertips, 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 skeleton 414. In some embodiments, location and movements of these key feature points over multiple image frames are used by the controller 110 to determine the hand gestures performed by the hand or the current state of the hand, in accordance with some embodiments.

[0212] FIG. 5 illustrates an example embodiment of the eye tracking device 130 (FIG. 1 A). In some embodiments, the eye tracking device 130 is controlled by the eye tracking unit 243 (FIG. 2) to track the position and movement of the user’s gaze with respect to the scene 105 or with respect to the XR content displayed via the display generation component 120. In some embodiments, the eye tracking device 130 is integrated with the display generation component 120. For example, in some embodiments, when the display generation component 120 is a head-mounted device such as 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 device 130 is separate from the display generation component 120. For example, 1010472 72Attorney Docket No. P69888W01 / 77770000840501when display generation component is a handheld device or a XR chamber, the eye tracking device 130 is optionally a separate device from the handheld device or XR chamber. In some embodiments, the eye tracking device 130 is a head-mounted device or part of a headmounted device. In some embodiments, the head-mounted eye-tracking device 130 is optionally used in conjunction with a display generation component that is also headmounted, or a display generation component that is not head-mounted. In some embodiments, the eye tracking device 130 is not a head-mounted device and is optionally used in conjunction with a head-mounted display generation component. In some embodiments, the eye tracking device 130 is not a head-mounted device and is optionally part of a non-head-mounted display generation component.

[0213] In some embodiments, the display generation component 120 uses 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.

[0214] As shown in FIG. 5, in some embodiments, eye tracking device 130 (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 NIR 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 device1010472 73Attorney Docket No. P69888W01 / 77770000840501130 optionally 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 controller 110. 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.

[0215] In some embodiments, the eye tracking device 130 is calibrated using a devicespecific calibration process to determine parameters of the eye tracking device for the specific operating environment 100, 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 userspecific 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 device 130, 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 accordance with some embodiments.

[0216] As shown in FIG. 5, the eye tracking device 130 (e.g., 130A or 130B) includes eye lens(es) 520, and a gaze tracking system that includes at least one eye tracking camera 540 (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 source 530 (e.g., IR or NIR light sources such as an array or ring of NIR light-emitting diodes (LEDs)) that emit light (e.g., IR or NIR light) towards the user’s eye(s) 592. The eye tracking cameras 540 may be pointed towards mirrors 550 located between the user’s eye(s) 592 and a display 510 (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) 592 while allowing visible light to pass (e.g., as shown in the top portion of FIG. 5), or alternatively may be pointed towards the user’s eye(s) 592 to receive reflected IR or NIR light from the eye(s) 592 (e.g., as shown in the bottom portion of FIG. 5).

[0217] In some embodiments, the controller 110 renders AR or VR frames 562 (e.g., left and right frames for left and right display panels) and provides the frames 562 to the display 1010472 74Attorney Docket No. P69888W01 / 77770000840501510. The controller 110 uses gaze tracking input 542 from the eye tracking cameras 540 for various purposes, for example in processing the frames 562 for display. The controller 110 optionally estimates the user’s point of gaze on the display 510 based on the gaze tracking input 542 obtained from the eye tracking cameras 540 using the glint-assisted methods or other suitable methods. The point of gaze estimated from the gaze tracking input 542 is optionally used to determine the direction in which the user is currently looking.

[0218] The following describes several possible use cases for the user’s current gaze direction and is not intended to be limiting. As an example use case, the controller 110 may render virtual content differently based on the determined direction of the user’s gaze. For example, the controller 110 may generate virtual content at a higher resolution in 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 controller 110 may 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 display 510. As another example use case, the eye lenses 520 may be focusable lenses, and the gaze tracking information is used by the controller to adjust the focus of the eye lenses 520 so that the virtual object that the user is currently looking at has the proper vergence to match the convergence of the user’s eyes 592. The controller 110 may leverage the gaze tracking information to direct the eye lenses 520 to adjust focus so that close objects that the user is looking at appear at the right distance.

[0219] In some embodiments, the eye tracking device is part of a head-mounted device that includes a display (e.g., display 510), two eye lenses (e.g., eye lens(es) 520), eye tracking cameras (e.g., eye tracking camera(s) 540), and light sources (e.g., illumination sources 530 (e.g., IR or NIR LEDs)) mounted in a wearable housing. The light sources emit light (e.g., IR or NIR light) towards the user’s eye(s) 592. In some embodiments, the light sources may be arranged in rings or circles around each of the lenses as shown in FIG. 5. In some embodiments, eight illumination sources 530 (e.g., LEDs) are arranged around each lens 520 as an example. However, more or fewer illumination sources 530 may be used, and other arrangements and locations of illumination sources 530 may be used.1010472 75Attorney Docket No. P69888W01 / 77770000840501

[0220] In some embodiments, the display 510 emits 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) 540 is given by way of example and is not intended to be limiting. In some embodiments, a single eye tracking camera 540 is located on each side of the user’s face. In some embodiments, two or more NIR cameras 540 may be used on each side of the user’s face. In some embodiments, a camera 540 with a wider field of view (FOV) and a camera 540 with a narrower FOV may be used on each side of the user’s face. In some embodiments, a camera 540 that operates at one wavelength (e.g., 850nm) and a camera 540 that operates at a different wavelength (e.g., 940nm) may be used on each side of the user’s face.

[0221] Embodiments of the gaze tracking system as illustrated in FIG. 5 may, 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.

[0222] FIG. 6 illustrates a glint-assisted gaze tracking pipeline, in accordance with some embodiments. In some embodiments, the gaze tracking pipeline is implemented by a glint-assisted gaze tracking system (e.g., eye tracking device 130 as illustrated in FIGS. 1 A and 5). 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.

[0223] As shown in FIG. 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 at 610. As indicated by the arrow returning to element 600, 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.

[0224] At 610, for the current captured images, if the tracking state is YES, then the method proceeds to element 640. At 610, if the tracking state is NO, then as indicated at 6201010472 76Attorney Docket No. P69888W01 / 77770000840501the images are analyzed to detect the user’s pupils and glints in the images. At 630, if the pupils and glints are successfully detected, then the method proceeds to element 640.Otherwise, the method returns to element 610 to process next images of the user’s eyes.

[0225] At 640, if proceeding from element 610, the current frames are analyzed to track the pupils and glints based in part on prior information from the previous frames. At 640, if proceeding from element 630, the tracking state is initialized based on the detected pupils and glints in the current frames. Results of processing at element 640 are 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. At 650, if the results cannot be trusted, then the tracking state is set to NO at element 660, and the method returns to element 610 to process next images of the user’s eyes. At 650, if the results are trusted, then the method proceeds to element 670. At 670, the tracking state is set to YES (if not already YES), and the pupil and glint information is passed to element 680 to estimate the user’s point of gaze.

[0226] FIG. 6 is 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 system 101 for providing XR experiences to users, in accordance with various embodiments.

[0227] In some embodiments, the captured portions of real-world environment 602 are 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 environment 602.

[0228] 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 physical1010472 77Attorney Docket No. P69888W01 / 77770000840501environment 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).

[0229] 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.

[0230] 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 or1010472 78Attorney Docket No. P69888W01 / 77770000840501viewpoint 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 1010472 79Attorney Docket No. P69888W01 / 77770000840501starting 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.

[0231] 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.1010472 80Attorney Docket No. P69888W01 / 77770000840501

[0232] 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 1010472 81Attorney Docket No. P69888W01 / 77770000840501object, 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.

[0233] 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.

[0234] 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 and1010472 82Attorney Docket No. P69888W01 / 77770000840501orientations 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).

[0235] 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.

[0236] As described herein, content is automatically generated by one or more computers in response to a request to generate the content. The automatically-generated content is optionally generated on-device (e.g., generated at least in part by a computer system at which a request to generate the content is received) and / or generated off-device (e.g., generated at least in part by one or more nearby computers that are available via a local network or one or more computers that are available via the internet). This automatically-generated content optionally includes visual content (e.g., images, graphics, and / or video), audio content, and / or text content.1010472 83Attorney Docket No. P69888W01 / 77770000840501

[0237] In some embodiments, novel automatically-generated content that is generated via one or more artificial intelligence (Al) processes is referred to as generative content (e.g., generative images, generative graphics, generative video, generative audio, and / or generative text). Generative content is typically generated by an Al process based on a prompt that is provided to the Al process. An Al process typically uses one or more Al models to generate an output based on an input. An Al process optionally includes one or more pre-processing steps to adjust the input before it is used by the Al model to generate an output (e.g., adjustment to a user-provided prompt, creation of a system-generated prompt, and / or Al model selection). An Al process optionally includes one or more post-processing steps to adjust the output by the Al model (e.g., passing Al model output to a different Al model, upscaling, downscaling, cropping, formatting, and / or adding or removing metadata) before the output of the Al model used for other purposes such as being provided to a different software process for further processing or being presented (e.g., visually or audibly) to a user. An Al process that generates generative content is sometimes referred to as a generative Al process.

[0238] A prompt for generating generative content can include one or more of one or more words (e.g., a natural language prompt that is written or spoken), one or more images, one or more drawings, and / or one or more videos. Al processes can include machine learning models including neural networks. Neural networks can include transformer-based deep neural networks such as large language models (LLMs). Generative pre-trained transformer models are a type of LLM that can be effective at generating novel generative content based on a prompt. Some Al processes use a prompt that includes text to generate either different generative text, generative audio content, and / or generative visual content. Some Al processes use a prompt that includes visual content and / or an audio content to generate generative text (e.g., a transcription of audio and / or a description of the visual content). Some multi-modal Al processes use a prompt that includes multiple types of content (e.g., text, images, audio, video, and / or other sensor data) to generate generative content. A prompt sometimes also includes values for one or more parameters indicating an importance of various parts of the prompt. Some prompts include a structured set of instructions that can be understood by an Al process that include phrasing, a specified style, relevant context (e.g., starting point content and / or one or more examples), and / or a role for the Al process.1010472 84Attorney Docket No. P69888W01 / 77770000840501

[0239] Generative content is generally based on the prompt but is not deterministically selected from pre-generated content and is, instead, generated using the prompt as a starting point. In some embodiments, pre-existing content (e.g., audio, text, and / or visual content) is used as part of the prompt for creating generative content (e.g., the pre-existing content is used as a starting point for creating the generative content). For example, a prompt could request that a block of text be summarized or rewritten in a different tone, and the output would be generative text that is summarized or written in the different tone. Similarly a prompt could request that visual content be modified to include or exclude content specified by a prompt (e.g., removing an identified feature in the visual content, adding a feature to the visual content that is described in a prompt, changing a visual style of the visual content, and / or creating additional visual elements outside of a spatial or temporal boundary of the visual content that are based on the visual content). In some embodiments, a random or pseudo-random seed is used as part of the prompt for creating generative content (e.g., the random or pseud-random seed content is used as a starting point for creating the generative content). For example when generating an image from a diffusion model, a random noise pattern is iteratively denoised based on the prompt to generate an image that is based on the prompt. While specific types of Al processes have been described herein, it should be understood that a variety of different Al processes could be used to generate generative content based on a prompt.USER INTERFACES AND ASSOCIATED PROCESSES

[0240] 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 a one or more output devices (e.g., optionally including one or more display generation components) and one or more sensors, including one or more optical sensors, and, optionally, one or more spatial information sensors.

[0241] FIGS. 7A-7Q illustrate examples of techniques and systems for scanning a physical environment and providing scan results. FIG. 8 is a flow diagram of an exemplary method 800 for scanning a physical environment and providing scan results. The user interfaces in FIGS. 7A-7Q are used to illustrate the processes described below, including the processes in FIG. 8.1010472 85Attorney Docket No. P69888W01 / 77770000840501

[0242] FIGS. 7A-7B illustrate computer system 700 receiving one or more inputs requesting to initiate active scanning of the physical environment using one or more optical sensors (e.g., 706A, 706B, and / or 706C), such as imaging sensors (e.g., visible light and / or IR cameras), depth sensors (e.g., structural light sensors, time-of-flight sensors (e.g., LIDAR), and / or stereoscopic camera sensors), and / or light sensors. In addition to the one or more optical sensors, in some embodiments, computer system 700 includes one or more other sensors, such as one or more spatial information sensors (e.g., accelerometers, gyroscopes, magnetometers, inertial measurement units (IMUs), and / or location sensors) and / or one or more other sensors (e.g., capacitive sensors, intensity sensors, motion sensors, vibration sensors, audio sensors, temperature sensors, and / or biometric sensors). In some embodiments, computer system 700 includes one or more audio generation components (e.g., an audio controller, one or more speakers, and / or other integrated and / or connected audio output devices) and / or tactile output generation components (e.g., haptic generators).

[0243] Computer system 700 includes wrist-worn device (e.g., smart watch) 700A, illustrated in FIGS. 7A-7B from the side (e.g., FIG. 7A) and front (e.g., FIG. 7B), which includes a set of hardware input devices including hardware button 702A and crown 702B (e.g., a depressible and rotatable input device), display 704 including a touch-sensitive surface, and optical sensors 706A and 706B (illustrated in FIG. 7B). For example, as further described with respect to FIGS. 11 A and 1 IL, optical sensor 706A is oriented within wrist-worn device 700A to face towards the environment (e.g., forward) when display 704 is oriented towards the eyes of a user wearing wrist-worn device 700A, and optical sensor 706B is oriented to face towards the user (e.g., rearward) when display 704 is oriented towards the eyes of the user. In some embodiments, computer system 700 includes HMD 700B, illustrated in FIGS. 7A-7B from the side (e.g., FIG. 7A) and front (e.g., 7B), which includes one or more optical sensors 706C and / or one or more other hardware components (e.g., display generation components, hardware input devices, and / or sensors) as described with respect to HMD devices 1-100 and / or 6-100. For example, the one or more optical sensors 706C include one or more environment-facing (e.g., forward) optical sensors (e.g., scene cameras 6-106 and / or first depth sensor 6-108) and / or optical sensors oriented in other directions (e.g., downward facing cameras 6-114, jaw cameras 6-118, and / or side cameras 6-118). For example, in the following description, terms such as “front,” “forward,” and / or “environment-facing” refer to optical sensors oriented / directed substantially in the direction1010472 86Attorney Docket No. P69888W01 / 77770000840501of the horizontal axis of axes 1130 (e.g., described further with respect to FIG. 1 IL), the frame of reference of the hardware (e.g., device housing) of computer system 700.

[0244] In some embodiments, computer system 700 is implemented using (e.g., in conjunction with computer system 700) one or more user devices (e.g., mobile phones, tablet computers, laptop computers, and / or wearable electronic devices (e.g., smart watches and / or head-mounted devices (HMDs))), remote devices (e.g., servers and / or network-connected devices), and / or peripheral devices (e.g., external storage drives, microphones, speakers, and / or hardware input devices). In some embodiments, one or more of the hardware components described above (e.g., the sensors, input devices, and / or output devices) are housed (e.g., included) in the same device. For example, wrist-worn device 700A includes both optical sensors (e.g., 706A and / or 706B) and one or more spatial information sensors (e.g., sensors tracking the movement, orientation, and / or location of wrist-worn device 700A). In some embodiments, one or more of the hardware components described above are housed in different devices. For example, computer system 700 provides outputs via display 704 housed in wrist-worn device 700A but obtains sensor data via one or more optical sensors (e.g., optical sensors 706C) and one or more spatial information sensors housed in HMD 700B.

[0245] At FIGS. 7A-7B, while displaying user interface 707 (e.g., a watch face user interface), computer system 700 receives one or more inputs (e.g., 708A, 708B, 708C, 708D, 708E, and / or 708F) requesting to initiate active scanning of the physical environment using the one or more optical sensors (e.g., 706A, 706B, and / or 706C). Input 708A, a speech input detected using one or more audio sensors of computer system 700, includes the naturallanguage request, “Look at this.” For example, computer system 700 processes spoken input 708A (e.g., using speech recognition, natural -language processing, and / or Al processing) to determine that the speech corresponds to a request to scan the physical environment using the one or more optical sensors. Input 708B includes a wrist-raise gesture detected using one or more spatial information sensors of computer system 700 (e.g., moving wrist-worn device 700A into a scanning position, as described further with respect to FIGS. 9A-9K and 1 IL). Input 708C includes a particular gesture (e.g., and / or combination of gestures) detected via the touch-sensitive surface of display 704, such as a downwards swipe from the edge of display 704 near optical sensor(s) 706A. Input 708D and input 708E include particular button press inputs (e.g., and / or combinations of button press inputs) detected via hardware button 702A and crown 702B. Input 708F includes a particular rotation input detected via1010472 87Attorney Docket No. P69888W01 / 77770000840501crown 702B, such as an input rotating crown 702B by at least a threshold amount and / or in a particular direction. In some embodiments, the input requesting to initiate active scanning of the physical environment includes another type of input, such as a touch input directed to a particular scanning affordance displayed via display 704 (e.g., as described with respect to FIG. 9A), an input detected by a hardware input device of HMD 700B, and / or a particular air gesture.

[0246] At FIG. 7C, in response to detecting the one or more inputs (e.g., 708A, 708B, 708C, 708D, 708E, and / or 708F) requesting to initiate active scanning of the physical environment using the one or more optical sensors, computer system 700 displays, via display 704, scanning user interface 710. Scanning user interface 710 includes scanning indicator 710A, a glow effect and / or animation displayed at the edge of display 704 near optical sensor(s) 706A (e.g., as further described with respect to FIGS. 9A-9K). Scanning user interface 710 indicates to a user that the active scan of the physical environment has been initiated, and thus, as the user positions the one or more optical sensors to capture optical scan data of the physical environment, computer system 700 will provide scan results based on features (e.g., objects, information, and / or characteristics) identified from the optical scan data as described herein with respect to FIGS. 7D-7O.

[0247] While scanning the physical environment in response to the request, computer system 700 (e.g., wrist-worn device 700A and / or HMD 700B) captures, using the one or more optical sensors, optical sensor data corresponding to field-of-view 712 of the physical environment and analyzes the optical sensor data to detect recognizable features (e.g., objects, information, and / or characteristics). For example, field-of-view 712 corresponds to a field-of-view of one or more environment- and / or forward-facing optical sensors, such as optical sensor 706A of wrist-worn device 700A and / or one or more scene cameras (e.g., 6-106) of HMD 700B. In some embodiments, computer system 700 implements one or more optical processing techniques and / or models, such as algorithmic image processing, optical character recognition, machine vision, generative Al, and / or machine learning techniques, to recognize and / or characterize (e.g., describe and / or classify) features of the physical environment from the image data, depth information, and / or luminance information captured via the optical sensors. For example, computer system 700 identifies visible objects and information of interest, such as people, pets, text, symbols, machine-readable codes (e.g., QR codes), plants, food items, landmarks, surroundings, displayed content, and / or user belongings. In some embodiments, while scanning the physical environment using the one or1010472 88Attorney Docket No. P69888W01 / 77770000840501more optical sensors, computer system 700 captures additional data from the physical environment using one or more other sensors, such as spatial information (e.g., information indicating how computer system 700, the one or more optical sensors, and / or the user are moving within the physical environment), audio data, and / or biometric data.

[0248] At FIG. 7D, computer system 700 identifies two features included in field-of-view 712: feature 712A, a sign for a restaurant with the text “Burger Cafe” and an image of a burger, and feature 712B, a QR code printed on a placard sitting on a table. As illustrated in FIG. 7D, in response to detecting feature 712A and feature 712B in field-of-view 712, computer system 700 displays symbolic representation 714A and symbolic representation 714B in scanning user interface 710. Symbolic representation 714A, which includes a map pin symbol, corresponds to feature 712A, and symbolic representation 714B, which includes a QR code symbol, corresponds to feature 712B. As illustrated in FIG. 7D, symbolic representations 714A and 714B are displayed without displaying another representation of field-of-view 712, such as a live- or near-live camera feed of image data captured using the optical sensors.

[0249] At FIG. 7D, symbolic representation 714A is selected as the active scan result, as indicated by the arrangement of symbolic representations 714A and 714B in scanning user interface 710 with symbolic symbolic representation 714A in front (e.g., partially overlapping symbolic representation 714B). Accordingly, the arrangement of symbolic representations in scanning user interface 710 does not necessarily reflect the arrangement of the corresponding features in the environment. While symbolic representation 714A is selected as the active scan results, computer system 700 displays additional information 716A, the text “add or share burger cafe,” indicating actions computer system 700 can take based on feature 712A (e.g., as described further with respect to FIGS. 7L-7M).

[0250] At FIGS. 7D-7E, field-of-view 712 of the optical sensors (e.g., 706A, 706B, and / or 706C) changes, for example, as a result of movement 718 sweeping wrist-worn device 700A (e.g., optical sensors 706A) to the right to capture a different portion of the physical environment. At FIG. 7E, computer system 700 identifies feature 712C, a plate with a burger and fries sitting on the table, which is now included in field-of-view 712. In response to detecting the new feature 712C, computer system 700 updates scanning user interface 710 to include symbolic representation 714C, which includes a fork-and-knife symbol corresponding to feature 712C. Additionally, computer system 700 generates nonvisual output 720A, an audio output such as a chime or notification tone, and nonvisual output 1010472 89Attorney Docket No. P69888W01 / 77770000840501720B, a tactile output (e.g., vibration), indicating the detection of feature 712C. Although field-of-view 712 no longer includes feature 712A (e.g., the restaurant sign) at FIG. 7E, computer system 700 continues to display the corresponding symbolic representation 714A. In some embodiments, computer system 700 continues to display symbolic representation 714A for at least a predetermined duration of time (e.g., 0.5s, Is, 2s, 5s, 10s, or 30s) after the optical sensors stop detecting feature 712A in field-of-view 712. In some embodiments, computer system 700 continues to display symbolic representation 714A after the optical sensors stop detecting feature 712A until maintaining display of symbolic representation 714A would cause the number of symbolic representations displayed in scanning user interface 710 to exceed a capacity (e.g., 2, 3, 4, 5, 7, or 10 symbolic representations), for example, if computer system 700 were to add another symbolic representation based on detecting another feature in field-of-view 712 (e.g., as further described with respect to FIGS.7N-7O).

[0251] As illustrated in FIG. 7E, symbolic representation 714C is selected as the active scan result (e.g., as the newest scan result), so computer system 700 updates the arrangement of the symbolic representations 714A-714C to place symbolic representation 714C in front (e.g., partially overlapping symbolic representations 714A and 714B) and displays additional information 716C, the text “log meal,” indicating an action that computer system 700 can take based on feature 712C (e.g., as described further with respect to FIG. 7K). Symbolic representations 714A and 714B are also displayed at a smaller size than symbolic representation 714C. For example, the sizing of the symbolic representations corresponds to their order in the arrangement, with symbolic representation 714C displayed at the largest size, symbolic representation 714B at a medium size, and symbolic representation 714B at the smallest size.

[0252] At FIG. 7F, while displaying symbolic representations 714A-714C, computer system 700 detects one or more inputs (e.g., 722A, 722B, 722C, 722D, 722E, 722F, and / or 722G) for reviewing the scan results. Input 722A and input 722B are movements detected using one or more spatial information sensors of computer system 700 that correspond to the user reviewing the symbolic representations on display 704. For example, input 722A corresponds to the user rotating wrist-worn device 700A to orient display 704 towards the user’s eyes, and input 722B corresponds to the user rotating HMD 700B to look down at display 704. Input 722C includes a particular gesture (e.g., and / or combination of gestures), detected via the touch-sensitive surface of display 704, corresponding to navigating through1010472 90Attorney Docket No. P69888W01 / 77770000840501the displayed symbolic representations, such as a tap input directed to symbolic representation 714B and / or a swipe input moving from near symbolic representation 714B towards the position of symbolic representation 714C (e.g., the position of the currently-selected symbolic representation in the arrangement). Input 722D and input 722E include particular button press inputs (e.g., and / or combinations of button press inputs) detected via hardware button 702A and crown 702B. Input 722F includes a particular rotation input detected via crown 702B, such as an input rotating crown 702B by at least a threshold amount and / or in a particular direction. Input 722G includes a particular air gesture (e.g., or combination of air gestures), detected via the optical sensors (e.g., 706A, 706B, and / or 706C), corresponding to navigating through the displayed symbolic representations, such as an air pinch and / or air swipe.

[0253] In response to detecting the one or more inputs (e.g., 722A, 722B, 722C, 722D, 722E, 722F, and / or 722G) for reviewing the scan results, computer system 700 pauses updating the scan results based on changes to field-of-view 712. For example, because the movements of input 722A and input 722B correspond to the user reviewing the scan results on display 704 as opposed to moving the optical sensors to scan a different portion of the physical environment using optical sensors 706A, 706B, and / or 706C (e.g., as described with respect to movement 718), computer system 700 does not update scanning user interface 710 to add new symbolic representations and / or remove displayed symbolic representations, even if field-of-view 712 includes new features and / or no longer includes a previously-detected feature.

[0254] At FIG. 7G, symbolic representation 714B is selected as the active scan result in response to detecting input 722C, input 722F, and / or input 722G, which correspond to navigating through the displayed symbolic representations. For example, rotating crown 702B (e.g., input 722C) and / or swiping across the displayed symbolic representations using a touch and / or air gesture (e.g., input 722F and / or input 722G) causes computer system 700 to successively select different symbolic representations, scrolling and / or cycling the selection in a direction and / or by an amount corresponding to the direction and / or magnitude of rotation / movement. As another example, inputs directed to a particular displayed symbolic representation other than the currently-selected symbolic representation (e.g., input 722F and / or input 722G) cause computer system 700 to select the particular displayed symbolic representation.1010472 91Attorney Docket No. P69888W01 / 77770000840501

[0255] As illustrated in FIG. 7G, when symbolic representation 714B is selected as the active scan result, computer system 700 arranges the symbolic representations with symbolic representation 714B in front (e.g., in the position occupied by symbolic representation 714C in FIG. 7E) and at the largest size, symbolic representation 714C in the middle and at the medium size, and symbolic representation 714A in the back and at the smallest size. In some embodiments, in response to detecting input 722C, input 722F, and / or input 722G, computer system 700 animates the symbolic representations rearranging, for instance, cycling through the different sizes and positions as the selection changes. Computer system 700 also displays additional information 716B, the text “order food,” indicating an action computer system 700 can take based on feature 712B (e.g., as described further with respect to FIGS. 7H-7I).

[0256] At FIG. 7G, while symbolic representation 714B is selected as the active scan result, computer system 700 detects one or more selection inputs (e.g., 724A, 724B, 724C, 724D, and / or 724E) of symbolic representation 714B, such as touch input 724A directed to symbolic representation 714B on the touch-sensitive surface of display 704, input 724B rotating crown 702B (e.g., in a particular direction and / or by a particular amount), input 724C pressing crown 702B, input 724D pressing hardware button 702A, and / or air gesture 724E (e.g., a particular air gesture and / or combination of air gestures).

[0257] In response to detecting the one or more selection inputs (e.g., 724A, 724B, 724C, 724D, and / or 724E) of symbolic representation 714B, at FIG. 7H, computer system 700 displays scan result user interface 726, a user interface for reviewing scan results in more detail (e.g., while scanning is paused). Scan result user interface 726 includes return affordance 726A, which navigates back to scanning user interface 710 and / or resumes (e.g., un-pauses) scanning when selected, as described in further detail with respect to FIGS. 7M-7N.

[0258] As illustrated in FIG. 7H, scan result user interface 726 includes scan result stack 728, a scrollable user interface element that presents scan results corresponding to scanned features 712A-712C. As the one or more selection inputs (e.g., 724A, 724B, 724C, 724D, and / or 724E) were directed to symbolic representation 714B and / or because symbolic representation 714B was selected as the active scan result when the one or more selection inputs were received, at FIG. 7H, computer system 700 initially displays scan result stack 728 with scan result 728 A, which corresponds to feature 712B / symbolic representation 714B, at the top. Scan result 728A is an affordance with the text “order more food” and an icon of a burger, indicating an action computer system 700 can take based on feature 712B, in 1010472 92Attorney Docket No. P69888W01 / 77770000840501particular, opening a URL (e.g., web link and / or application deep-link) encoded by the QR code scanned on the table placard. Computer system 700 additionally displays symbolic representation 714B in scan result user interface 726 while scan result 728A is at the top of scan result stack 728, indicating the source of the provided action.

[0259] At FIG. 7H, while scan result 728A is displayed at the top of scan result stack 728, computer system 700 detects one or more inputs selecting scan result 728A, such as input 730A (e.g., a touch input directed to scan result 728A on display 704), input 730B (e.g., a press input detected by crown 702B), input 730C (e.g., a press input detected by hardware button 702A), and / or input 720D (e.g., a particular air gesture and / or combination of air gestures). In response to detecting the one or more inputs selecting scan result 728A, computer system 700 opens the URL encoded by the QR code of feature 712B, displaying user interface 732 as illustrated in FIG. 71, a restaurant ordering user interface for the table on which the scanned placard (e.g., feature 712B) is placed. For example, the user can interact with user interface 732 using touch, hardware, air gesture, and / or spoken inputs, such as input 734A, selecting a veggie burger item from the menu in user interface 732 to add to an order for the user’s table. Computer system 700 additionally displays user interface 732 with return affordance 732A, which, when selected (e.g., via input 734B), causes computer system 700 to navigate back to scan result user interface 726 (e.g., as illustrated in FIG. 7J).

[0260] While displaying scan result user interface 726 with scan result 728A at the top of scan result stack 728 at FIG. 7J, computer system 700 detects one or more inputs for navigating scan result stack 728, such as input 736 A swiping up across scan result stack 728 and / or input 736B rotating crown 702B. At FIG. 7K, in response to the one or more inputs for navigating scan result stack 728, computer system 700 updates scan result user interface 726 to include symbolic representation 714C and to display scan result 728B, which corresponds to feature 712C / symbolic representation 714C, at the top of scan result stack 728.

[0261] Scan result 728B corresponds to scanned feature 712C, the plate with the burger and fries sitting in front of the user on the table. As illustrated in FIG. 7K, scan result 728B includes a description of an action of logging a meal in a meal-tracking application (e.g., the text “log chicken burger” and / or an icon for the meal-tracking application) and additional information based on scanned feature 712C (e.g., text with the estimated calorie count, “cal: 670”). In some embodiments, computer system 700 identifies the action, information for performing the action (e.g., one or more parameters of a task), and / or the additional 1010472 93Attorney Docket No. P69888W01 / 77770000840501information based on scanned feature 712C (e.g., based on identifying one or more specific food items from the optical scan data) and / or other sensor data and / or contextual information, such as spatial information indicating the user picking up and eating the burger and fries, audio data detected when the user ordered the meal, and / or calorie estimate information provided by the meal-tracking application. As described with respect to scan result 728A and FIGS. 7H-7I, in response to detecting one or more inputs selecting scan result 728B (e.g., touch input 737A, button input 737B, button input 737C, and / or air gesture input 737D), computer system 700 initiates performance of the action of logging the chicken burger meal (e.g., via one or more API calls to the meal-tracking application), for example, causing the meal-tracking application to log the meal and / or displaying a user interface of the mealtracking application populated with information about the chicken burger meal.

[0262] At FIG. 7K, computer system 700 detects one or more inputs for navigating scan result stack 728, such as input 738 A swiping up across scan result stack 728 and / or input 738B rotating crown 702B. At FIG. 7L, in response to the one or more inputs for navigating scan result stack 728, computer system 700 updates scan result user interface 726 to include symbolic representation 714A and to display scan result 728C, which corresponds to feature 712A (e.g., the restaurant sign) and / or symbolic representation 714A, at the top of scan result stack 728. As illustrated in FIG. 7K, scan result 728C includes a description of an action of adding the identified restaurant to a “Favorites” collection in a maps application (e.g., the text “Add Burger Cafe to favorites” and / or an icon for the maps application), and can be selected (e.g., via input 740A, 740B, 740C, and / or 740D) to cause the action to be performed.

[0263] In response to detecting, at FIG. 7L, one or more inputs for navigating scan result stack 728 (e.g., swipe input 742A and / or rotation input 742B), at FIG. 7M, computer system 700 scan result user interface 726 to include scan result 728D, another scan result corresponding to feature 712A / symbolic representation 714A, at the top of scan result stack 728. For example, based on detecting feature 712A, computer system 700 identifies multiple candidate actions for interacting with the identified restaurant. As illustrated in FIG. 7M, scan result 728D includes a description of a second action of sharing the identified restaurant location (e.g., the text “Share Burger Cafe” and / or a share icon), and can be selected (e.g., via input 744 A, 744B, 744C, and / or 744D) to cause the second action to be performed. For example, selecting scan result 728D causes a sharing user interface to be displayed with options for, e.g., copying the restaurant location to a data clipboard, sending the restaurant1010472 94Attorney Docket No. P69888W01 / 77770000840501location to another person via a communication application, and / or exporting the restaurant location to a particular application.

[0264] Additionally or alternatively to navigating through scan result stack 728 in scan result user interface 726 as described herein with respect to FIGS. 7J-7M, computer system 700 displays scan user interface 726 with a particular scan result (e.g., 728A, 728B, 728C, and / or 728D) at the top of scan result stack 728 in response to selection inputs detected while displaying scanning user interface 710 with the symbolic representation corresponding to the particular scan result selected as the active symbolic representation. Accordingly, the user can review scan results and access additional actions / information either via the symbolic representations in scanning user interface 710 (e.g., as described with respect to FIGS. 7F-7G) or the scan results user interface 726.

[0265] At FIG. 7M, computer system 700 detects one or more inputs (e.g., 746A, 746B, 746C, and / or 746D) for resuming scanning the physical environment using the one or more optical sensors. Input 746A is an input (e.g., a touch and / or air gesture input) selecting return affordance 726A. Input 746 includes a particular gesture (e.g., and / or combination of gestures), detected via the touch- sensitive surface of display 704, corresponding to returning to scanning user interface 710, such as a downwards swipe across scan result user interface 726. Input 746C and input 746D are movements detected using one or more spatial information sensors of computer system 700 that correspond to the user ceasing reviewing the symbolic representations on display 704 and / or returning to a scanning position (e.g., as further described with respect to FIG. 9C). For example, the movements correspond to rotating wrist-worn device 700A and / or HMD 700B to orient optical sensors 706A, 706B, and / or 706C out towards the physical environment.

[0266] At FIG. 7N, after detecting the one or more inputs (e.g., 746A, 746B, 746C, and / or 746D) for resuming scanning the physical environment using the one or more optical sensors, computer system 700 displays scanning user interface 710 and detects a change to field-of-view 712 of the optical sensors (e.g., 706A, 706B, and / or 706C). In particular, computer system 700 detects feature 712D, a bird, landing on the placard on the user’s table. As illustrated in FIG. 7N, although scanning the physical environment using the one or more optical sensors was resumed (e.g., in response to inputs 746A, 746B, 746C, and / or 746D), computer system 700 does not immediately update scanning user interface 710 in response to detecting feature 712D, instead waiting until the new feature is detected for at least a threshold period of time (e.g., 0.1s, 0.5s, Is, 2s, 3s, 5s, 10s, or 30s).1010472 95Attorney Docket No. P69888W01 / 77770000840501

[0267] At FIG. 70, once feature 712D has been detected in field-of-view 712 for at least the threshold period of time, computer system 700 updates scanning user interface to include symbolic representation 714D, which includes a bird symbol corresponding to feature 712D being identified (e.g., using one or more optical processing techniques and / or models) as a bird. As illustrated in FIG. 70, computer system 700 displays symbolic representations 714B-714D arranged with symbolic representation 714D in front and displayed at the largest size, indicating that symbolic representation 714D is selected as the active symbolic representation. Computer system 700 additionally generates nonvisual output 748A, an audio output such as a chime or notification tone, and nonvisual output 748B, a tactile output (e.g., vibration), indicating the detection of feature 712D, and displays additional information 716D, the text “Learn more,” indicating the availability of additional information system 700 can provide based on feature 712D.

[0268] As illustrated in FIG. 70, upon displaying symbolic representation 714D, computer system 700 ceases displaying symbolic representation 714A corresponding to feature 712A, the restaurant sign that is no longer detected in field-of-view 712, based on a determination that displaying symbolic representation 714D for the newly-detected feature 712D would cause the number of symbolic representations displayed in scanning user interface 710 to exceed a capacity of three. Accordingly, computer system 700 provides users with flexibility to review scan results even as field-of-view 712 changes, while also providing up-to-date scan results and avoiding over-crowding scanning user interface 710 with symbolic representations of previously-detected features.

[0269] At FIG. 7P, computer system 700 ceases detecting feature 712D in field-of-view 712 when the bird flies away from the table. As illustrated in FIG. 7P, computer system 700 maintains displaying symbolic representation 714D for at least a threshold period of time (e.g., and / or until a new feature is detected in field-of-view 712 for which a symbolic representation is displayed), allowing the user to review and interact with symbolic representation 714D even after the bird flies away. In particular, in response to one or more inputs selecting symbolic representation 714D, such as input 750A directed to symbolic representation 714D, input 750A directed to additional information 716D, and / or inputs 750C and / or 750D detected while symbolic representation 714D is selected as the active symbolic representation, computer system 700 displays user interface 752 as illustrated in FIG. 7Q. Alternatively, in response to the one or more inputs selecting symbolic representation 714D, computer system 700 displays scan result user interface 726 with a scan result corresponding1010472 96Attorney Docket No. P69888W01 / 77770000840501to feature 712D displayed at the top of scan result stack 728 (e.g., as described with respect to FIG. 7H), which can be selected to display user interface 752.

[0270] As illustrated in FIG. 7Q, user interface 752 provides additional information based on feature 712D, for instance, information 752 A, identifying the bird’s common species name (e.g., the text “Western Scrub Jay”), and information 752B, providing the bird’s geographic range (e.g., the text “Range: Pacific coast”) and / or other content related to feature 712D (e.g., accessible by navigating user interface 752 using inputs such as 754A, a rotation of crown 702B). For example, computer system 700 analyzes the optical scan data using the one or more optical processing techniques and / or models to identify information 752A and obtains information 752B by performing a web search, retrieving information from a birdwatching application, and / or generating Al content based on the identified bird. User interface 752 also includes return affordance 752C, which, when selected (e.g., via input 754B), causes computer system 700 to display scanning user interface 710 and resume scanning the physical environment (e.g., as described with respect to FIG. 7N).

[0271] In some embodiments, computer system 700 ceases scanning the physical environment in response to particular inputs received while scanning the physical environment (e.g., displaying scanning user interface 710) and / or providing scan results to the user (e.g., via scan result user interface 726, user interface 732, user interface 752, and / or another user interface accessed via the symbolic representations and / or scan result stack 728), such as a particular press of hardware button 702A and / or crown 702B, a swipe in a particular direction across the touch-sensitive surface of display 704, and / or a particular air gesture. For example, in response to input 754C (e.g., a press of hardware button 702A held for at least a threshold duration of time), computer system 700 resumes displaying user interface 707 (e.g., the watch face user interface).

[0272] Additional descriptions regarding FIGS. 7A-7Q are provided below in reference to method 800 described with respect to FIG. 8.

[0273] FIG. 8 is a flow diagram of an exemplary method 800 for scanning a physical environment and providing scan results, in some embodiments. In some embodiments, method 800 is performed at a computer system (e.g., computer system 101 in FIG. 1A and / or computer system 700) including a one or more display generation components (e.g., display generation component 120 in FIGS. 1 A, 3A, and 4 and / or display 704) (e.g., a display controller; a touch-sensitive display system; a display (e.g., integrated and / or connected), a1010472 97Attorney Docket No. P69888W01 / 777700008405013D display, a transparent display, a projector, and / or a heads-up display) and one or more optical sensors (e.g., 6-106, 6-108, 6-114, 6-118, 6-118, 706A, 706B, and / or 706C) (e.g., imaging sensors (e.g., visible light and / or IR cameras), depth sensors (e.g., structural light sensors, time-of-flight sensors (e.g., LIDAR), and / or stereoscopic camera sensors), and / or light sensors). In some embodiments, the computer system includes a wrist-worn device (e.g., 700A). In some embodiments, the optical sensors are housed within the same device as at least one display (e.g., 704) (e.g., the computer system includes a wrist-worn device that houses both a display and the one or more optical sensors). In some embodiments, the optical sensors point in a direction that is within a threshold range (e.g., within 10°, 30°, 45°, or 60°) of perpendicular to a plane of a display (e.g., as illustrated in FIG. 1 IL) (e.g., the optical sensors point in one or more directions that are within a threshold range of parallel to the surface of the display). In some embodiments, the computer system is optionally in communication with one or more motion and / or orientation sensors (e.g., accelerometers, gyroscopes, magnetometers, inertial measurement units (IMU), and / or location sensors). In some embodiments, the motion and / or orientation sensors measure the movement and / or orientation of the optical sensors (e.g., the IMU and optical sensors operate within the same inertial frame of reference). In some embodiments, the computer system is optionally in communication with one or more input devices, such as touch-sensitive surfaces (e.g., of display 704), hardware input devices (e.g., 702A and / or 702B) (e.g., hardware buttons, switches, keys, and / or dials), microphones, gesture input devices, air gesture input devices, and / or gaze input devices. In some embodiments, the computer system is optionally in communication with one or more additional sensors, such as capacitive sensors, intensity sensors, motion sensors, vibration sensors, audio sensors, temperature sensors, and / or biometric sensors. In some embodiments, method 800 is 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 processors 202 of computer system 101 (e.g., control 110 in FIG. 1 A). Some operations in method 800 are, optionally, combined and / or the order of some operations is, optionally, changed.

[0274] The computer system detects (802), in a portion (e.g., field-of-view and / or sensor capture area) of a physical environment captured via the one or more optical sensors (e.g., 712), a first set of one or more objects (e.g., 712A, 712B, 712C, 712D, 900 A, 900B, 900C, 1100A, 1100B, 1100C, HOOD, 1100E, HOOF, 1100G, and / or 1100H). For example, the1010472 98Attorney Docket No. P69888W01 / 77770000840501computer system processes the sensor data using optical processing techniques, such as algorithmic image processing, machine vision, and / or other machine learning techniques, to recognize features of the physical environment and identify visible objects and information of interest, such as people, pets, text, symbols, plants, food items, landmarks, surroundings, displayed content, and / or user belongings. In some embodiments, the computer system captures the portion of the physical environment via the one or more sensors in response to a user input (e.g., a request to scan the environment).

[0275] In response to detecting the first set of one or more objects (in some embodiments, and in accordance with a determination that the first set of one or more objects meet a set of object type criteria), the computer system displays (804), via the one or more display generation components, a first set of one or more symbolic representations (e.g., icons, text, and / or other user interface elements) corresponding to the first set of one or more objects (e.g., 714A, 714B, 714C, 714D, 912A, 912B, 912C, 1106A, 1106B, and / or 1106C), wherein the first set of one or more symbolic representations is displayed without displaying, via the one or more display generation components, a representation of the portion of the physical environment captured via the one or more optical sensors (e.g., as illustrated in FIGS. 7D-7G, 7N-7P, 91, 9K, and / or 1 ID) (e.g., displaying the symbolic representations without displaying optical sensor data, such as a live or near-live viewfinder of the field-of-view of the one or more cameras). Displaying symbolic representations of objects detected in a physical environment without displaying an optical representation of the physical environment (e.g., a live- or near-live viewfinder) provides improved control of computer system functionality without cluttering the user interface with additional displayed controls and provides improved visual feedback to the user, which reduces the power usage and improves the battery life of the computer system by enabling the user to use the device more quickly and efficiently. For example, displaying symbolic representations of detected objects provides users with information about a physical environment and / or computer system functionality related to the physical environment without expending additional processing or power resources to display a camera (or other optical sensor) feed, which also improves readability of the information (e.g., the symbolic representations isolate information about relevant objects in the physical environment from background information). Displaying symbolic representations of objects detected in a physical environment without displaying an optical representation of the physical environment also assists the user with interacting with the physical environment via the computer system (e.g., using optical scan data) and reduces the risk that transient visual1010472 99Attorney Docket No. P69888W01 / 77770000840501context is missed, which reduces the number of inputs needed to perform an operation (e.g., inputs to manually input context information about the physical environment and / or manually request feedback) and thus reduces the power usage and improves the battery life of the computer system by enabling the user to use the device more quickly and efficiently. For example, the symbolic representations provide the user with feedback on visual context detected by the computer system, allowing the user to confirm and review detected objects. Providing the symbolic representations also reduces the number of inputs needed to perform an operation, for example, by automatically surfacing information about relevant objects in the physical environment without requiring the user to manually input information about the physical environment and / or manually seek related functionality, which reduces the power usage and improves the battery life of the computer system by enabling the user to use the device more quickly and efficiently.

[0276] In some embodiments, displaying (804) the first set of one or more symbolic representations corresponding to the first set of one or more objects includes displaying a first symbolic representation corresponding to a first object of the first set of one or more objects and displaying a second symbolic representation (e.g., a different symbolic representation from the first symbolic representation) corresponding to a second object of the first set of one or more objects (e.g., a different object from the first object of the first set of one or more objects) (e.g., as illustrated in FIGS. 7D-7G, 7N-7P, 91, 9K, and / or 1 ID). In some embodiments, the first object and second object are different types of objects, and the first symbolic representation and the second symbolic representation have different appearances (e.g., different symbols, icons, text, and / or colors) corresponding to the different types.

[0277] In some embodiments, a spatial relationship between the first symbolic representation and the second symbolic representation (e.g., 714A, 714B, 714C, and / or 714D) with respect to a display (e.g., 704) of the one or more display generation components (e.g., the relative positioning, sizing, and / or ordering of the symbolic representations with respect to the frame of reference of the display) has a first value of a respective spatial relationship characteristic, and a spatial relationship between the first object and the second object (e.g., 712A, 712B, 712C, and / or 712D) with respect to the physical environment (e.g., the relative positioning, sizing, and / or ordering of the objects with respect to the frame of reference of a field-of-view of the environment) has a second value of the respective spatial relationship characteristic, wherein the second value is different from the first value (e.g., as illustrated in FIGS. 7D-7G and 7N-7P). For example, in the physical environment, the first1010472 100Attorney Docket No. P69888W01 / 77770000840501object is above the second object, but the first symbolic representation is displayed to the left of the second symbolic representation on the display. As another example, the first object is closer to the optical sensors than the second object (e.g., the second object is behind the first object), but the first symbolic representation is displayed partially behind the second symbolic representation on the display. In some embodiments, the spatial relationship between the first symbolic representation and the second symbolic representation on the display is based on one or more factors other than the spatial relationship between the first object and the second object with respect to the physical environment. For example, the symbolic representations are arranged based on relevance to the user, order of detection of the corresponding objects, and / or user interactions with the displayed symbolic representations, such as user inputs selecting a symbolic representation to be in focus.Displaying the symbolic representations in an arrangement that differs from the corresponding objects’ arrangement in the physical environment provides improved visual feedback to the user and assists the user with interacting with the physical environment via the computer system (e.g., using optical scan data). For example, in contrast to displaying an optical representation of the physical environment, the symbolic representations are arranged on a display in a manner that improves their legibility, provides the user with relevant information, and / or provides the user with feedback on the state of detection.

[0278] In some embodiments, while displaying (e.g., initially displaying in response to detecting the first set of one or more objects) a third symbolic representation (in some embodiments, the first symbolic representation, the second symbolic representation, or another symbolic representation) of the first set of one or more symbolic representations with a respective set of visual emphasis characteristics (e.g., visual characteristics, such as color, size, position, border effects, fill effects, opacity, brightness, contrast, and / or associated display elements and / or user interface objects, that indicate the third symbolic representation is currently selected / in focus) without displaying a fourth symbolic representation of the first set of one or more symbolic representations with the respective set of visual emphasis characteristics (e.g., as illustrated in FIGS. 7F, 7G, and / or 7P), the computer system detects (e.g., via the one or more optical sensors, a touch-sensitive surface, and / or a hardware button) a respective user input (e.g., 722A-722G, 724A-724E, and / or 750A-750E) (e.g., a touch input, gesture input, air gesture input, press input, and / or rotation input). For example, the currently-focused symbolic representation is displayed in front of the other symbolic representations (e.g., partially overlaying one or more other symbolic representations without1010472 101Attorney Docket No. P69888W01 / 77770000840501being overlaid by any other symbolic representations), at a larger size than the other symbolic representations, in a different color than the other symbolic representations (e.g., the focused symbolic representation is white, yellow, and / or red, while the other symbolic representations are gray, white, and / or blue), with a particular border effect (e.g., a bold keyline and / or an edge glow) not applied to the other symbolic representations, and / or with a user interface element (e.g., a text label, action affordance, and / or share affordance) not displayed with the other symbolic representations.

[0279] In some embodiments, in response to detecting the respective user input and in accordance with a determination that the respective user input satisfies a set of focus criteria (e.g., 722C, 722F, and / or 722G in FIG. 7F), the computer system displays the fourth symbolic representation of the first set of one or more symbolic representations with the respective set of visual emphasis characteristics without displaying the third symbolic representation of the first set of one or more symbolic representations with the respective set of visual emphasis characteristics (e.g., as illustrated in FIG. 7G). In some embodiments, the set of focus criteria includes a criterion that is satisfied when the respective user input does not include a selection input (e.g., a tap and / or press without movement) directed to the third symbolic representation. In some embodiments, if the set of symbolic representations includes three or more symbolic representations, the set of focus criteria includes a criterion that is satisfied when a characteristic (e.g., a location and / or direction of movement) of the respective user input corresponds to the fourth symbolic representation (e.g., different movement characteristics are used to change focus to different symbolic representations). In some embodiments, in response to detecting the respective user input, in accordance with a determination that the respective user input does not satisfy the set of focus criteria, the computer system forgoes changing the visual emphasis, surfaces additional information / options for the current focused symbolic representation, and / or changes the visual emphasis to a symbolic representation other than the third and fourth symbolic representations. Changing the visual emphasis of displayed symbolic representations corresponding to detected objects to indicate a currently-focused object provides improved visual feedback to the user, provides improved control of computer system functionality without cluttering the user interface with additional displayed controls and assists the user with interacting with the physical environment via the computer system (e.g., using optical scan data). For example, after scanning multiple objects, the visual emphasis clearly1010472 102Attorney Docket No. P69888W01 / 77770000840501indicates to the user which object is selected for further interactions as the user reviews the scan results.

[0280] In some embodiments, the third symbolic representation corresponds to a third object of the first set of one or more objects, and, in response to detecting the respective user input and in accordance with a determination that the respective user input corresponds to a selection of the third symbolic representation of the first set of one or more symbolic representations (e.g., 722D-722G, 724A-724E, and / or 750A-750E) (e.g., a tap and / or press input without movement directed to the current focused symbolic representation), the computer system displays, via the one or more display generation components, one or more additional user interface elements (e.g., 728 and / or 752) (e.g., text, symbols, icons, images, and / or user interface objects) corresponding to the third object of the first set of one or more objects (e.g., 728A corresponding to 714B, 728B corresponding to 714C, 728C and / or 728D corresponding to 714A, and / or 752A and / or 752B corresponding to 714D). For example, in response to a selection of the current focused symbolic representation, the computer system displays additional information about the detected third object and / or additional options (e.g., user interface objects for performing one or more actions) based on the detected third object. In some embodiments, if the respective user input corresponds to a selection of the third symbolic representation, the respective user input does not satisfy the focus criteria (e.g., the visual emphasis is not switched to another symbolic representation in response to a selection of the current focused symbolic representation). Displaying additional information related to a detected object in response to an interaction with the corresponding displayed symbolic representation (e.g., an input focusing and / or selecting the symbolic representation) provides improved visual feedback to the user, provides improved control of computer system functionality without cluttering the user interface with additional displayed controls and assists the user with interacting with the physical environment via the computer system. For example, after scanning multiple objects, the computer system surfaces related additional information and / or functionality to the user as the user reviews the corresponding symbolic representations.

[0281] In some embodiments, while displaying the first set of one or more symbolic representations, the computer system detects (e.g., via the one or more optical sensors, a touch-sensitive surface, and / or a hardware button) a first user input (e.g., 722C-722G, 724A-724E, and / or 750A-750E) (e.g., an air gesture, touch input, press input, and / or rotation input) directed to a respective symbolic representation of the first set of one or more symbolic1010472 103Attorney Docket No. P69888W01 / 77770000840501representations that corresponds to a respective object of the first set of one or more objects. For example, the first user input is detected at a location corresponding to a display location of the respective symbolic representation (e.g., a touch and / or air gesture directed to the location of the respective symbolic representation) and / or includes a movement in a direction corresponding to the respective symbolic representation (e.g., a gesture and / or rotation input in a direction corresponding to selecting and / or focusing the respective symbolic representation). In some embodiments, in response to detecting the first user input directed to the respective symbolic representation of the first set of one or more symbolic representations, the computer system displays, via the one or more display generation components, one or more additional user interface elements (e.g., 716A-716D, 728, 728 A-728D, 752, and / or 752A-752B) (e.g., text, symbols, icons, images, and / or user interface objects) corresponding to the respective object of the first set of one or more objects (e.g., as illustrated in FIGS. 7G-7H and / or 7Q). In some embodiments, the first user input satisfies the set of focus criteria for the respective symbolic representation, and the one or more additional user interface elements include one or more visual emphasis elements, such as a text label element that is displayed for the current focused symbolic representation. In some embodiments, the first user input corresponds to selection of a current focused symbolic representation (e.g., the symbolic representation currently displayed with the respective visual emphasis characteristics), and the additional user interface elements include additional information and / or options for the respective object. Providing additional information and / or options corresponding to a detected object in response to an input selecting the corresponding displayed symbolic representation provides improved visual feedback to the user, provides improved control of computer system functionality without cluttering the user interface with additional displayed controls and assists the user with interacting with the physical environment via the computer system. For example, the computer system displays the symbolic representations to allow users to both efficiently review one or more scanned objects and selectively access additional information and / or options for the scanned objects when relevant and / or desired.

[0282] In some embodiments, the one or more additional user interface elements corresponding to the respective object of the first set of one or more objects includes textual information corresponding to the respective object (e.g., 716A-716D, 728A-728D, and / or 752A-752B). For example, the textual information includes a text label of the respective object and / or its object type, a text description of the respective object and / or its object type,1010472 104Attorney Docket No. P69888W01 / 77770000840501text extracted from the object, and / or text indicating one or more additional options available for the object.

[0283] In some embodiments, the one or more additional user interface elements corresponding to the respective object of the first set of one or more objects includes a first user interface element that represents a first action associated with the respective object (e.g., 716A-716D and / or 728A-728D). In some embodiments, the user interface element includes a control element, such as a software button, link, and / or slider. In some embodiments, the user interface element includes an indication of the respective action, such as a text label, text description, action icon, and / or application icon. Displaying options for actions related to a detected object in response to an input selecting the corresponding displayed symbolic representation provides improved visual feedback to the user and assists the user with interacting with the physical environment via the computer system, for example, by informing users of actions the computer system can take that are relevant to the user’s environmental context (e.g., the detected objects) as the user interacts with the scan results.

[0284] In some embodiments, while displaying the one or more additional user interface elements corresponding to the respective object, the computer system detects (e.g., via the one or more optical sensors, a touch-s...
