Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to U.S. Provisional Patent Application No. 63 / 376,961, filed September 23, 2022, and U.S. Provisional Patent Application No. 63 / 506,095, filed June 4, 2023, the contents of which are incorporated herein by reference in their entireties for all purposes.

[0002] This relates generally to computer systems that provide computer-generated experiences, including but not limited to electronic devices that provide virtual reality and mixed reality experiences via a display. [Background technology]

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

[0004] Some methods and interfaces for interacting with environments that include at least some virtual elements (e.g., applications, augmented reality environments, mixed reality environments, and virtual reality environments) are cumbersome, inefficient, and limited. For example, systems that provide insufficient feedback for performing actions associated with virtual objects, systems that require a series of inputs to achieve a desired result in an augmented reality environment, and systems in which manipulating virtual objects is complex and error-prone create a significant cognitive burden for users and detract from the experience of the virtual / augmented reality environment. In addition, these methods are unnecessarily time-consuming, thereby wasting computer system energy. This latter consideration is particularly important in battery-operated devices.

[0005] Therefore, there is a need for a computer system having improved methods and interfaces for providing users with computer-generated experiences that make interaction with the computer system more efficient and intuitive for the user. Such methods and interfaces can optionally complement or replace conventional methods of providing users with extended reality experiences. Such methods and interfaces reduce the number, extent, and / or type of inputs from the user by helping the user understand the connection between the input provided and the device response to that input, thereby creating a more efficient human-machine interface.

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

[0007] There is a need for electronic devices with improved methods and interfaces for interacting with content within a three-dimensional environment. Such methods and interfaces can complement or replace conventional methods for interacting with content within a three-dimensional environment. Such methods and interfaces reduce the number, extent, and / or type of input from a user, creating a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges.

[0008] In some embodiments, the computer system displays virtual content indicating areas of high likelihood of interaction and displays the immersive virtual content. In some embodiments, the computer system stops displaying the immersive virtual content and displays areas of high likelihood of interaction. In some embodiments, the computer system generates an alert for physical objects obscured by the virtual content based on the attention. In some embodiments, the computer system reduces the visual salience of the virtual content to people in the physical environment based on the attention.

[0009] It should be noted that the various embodiments described above can be combined with any other embodiment described herein. The features and advantages described herein are not exhaustive, and many additional features and advantages will become apparent to those skilled in the art, particularly in light of the drawings, specification, and claims.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present disclosure relates to a user interface that provides a computer-generated (CGR) experience to a user, according to some embodiments.

[0027] The systems, methods, and GUIs described herein facilitate electronic device interaction with objects in a three-dimensional environment and provide improved ways to manipulate the objects.

[0028] In some embodiments, the computer system detects an input corresponding to a request to display the virtual content at an immersive level above a threshold immersion level. In some embodiments, the computer system displays a visual indication corresponding to an area of ​​high likelihood of interaction with the virtual content. In some embodiments, the input includes movement of a user of the computer system into an area of ​​the user's physical environment corresponding to the visual indication. In some embodiments, the computer system maintains display of a portion of a representation of the user's environment while displaying the virtual content at an immersive level above the threshold immersion level.

[0029] In some embodiments, the computer system detects an input corresponding to a request to reduce the visual salience of the virtual content. In some embodiments, the input includes movement of a user of the computer system out of an area of ​​the user's physical environment where the computer system anticipates possible interaction with the virtual content. In some embodiments, reducing the visual salience includes ceasing display of the virtual content.

[0030] In some embodiments, the computer system displays virtual content that obscures a physical object in the user's physical environment. In some embodiments, in accordance with a determination that the physical object is likely to conflict with the user's range of movement, the computer system generates an alert indicating the presence of the physical object. In some embodiments, based on the user's attention directed to the alert, the computer system reduces, maintains, or increases the salience of the alert.

[0031] In some embodiments, the computer system displays virtual content that obscures a person in the computer system's physical environment. In some embodiments, the computer system breaks through the virtual content, allowing visibility of the person through the virtual content. In some embodiments, the computer system alters visibility of the person through the virtual content based on attention of a user and / or the person.

[0032] FIGS. 1A-6 provide an illustration of an exemplary computer system for providing an XR experience to a user (as described below with respect to methods 800, 1000, 1200, and 1400).

FIGS. 8A-8F are flowcharts illustrating an exemplary method for displaying immersive virtual content and displaying virtual content showing areas where interaction is likely, according to some embodiments.

FIGS. 9A-9E illustrate an example computer system for reducing the visual salience of immersive virtual content and displaying areas where interaction is likely, according to some embodiments. FIGS. 10A-10G are flowcharts illustrating a method for reducing the visual salience of immersive virtual content and displaying areas where interaction is likely, according to some embodiments. The user interfaces of FIGS. 9A-9E are used to illustrate the process of FIGS. 10A-10G. 11A-11E illustrate an exemplary technique for generating alerts associated with physical objects in a user's environment, according to some embodiments. FIGS. 12A-12D illustrate a flow diagram of a method for generating alerts associated with physical objects in a user's environment, according to various embodiments. The user interfaces of FIGS. 11A-11E are used to illustrate the process of FIGS. 12A-12D. FIGS. 13A-13H illustrate an exemplary technique for modifying the visual salience of people in a three-dimensional environment based on one or more attention-related factors, according to some embodiments. FIGS. 14A-14H illustrate a flow diagram of a method for modifying the visual salience of people in a three-dimensional environment based on one or more attention-related factors, according to various embodiments. The user interfaces of FIGS. 13A-13H are used to illustrate the process of FIGS. 14A-14H.

[0033] The processes described below enhance device usability and make user-device interfaces more efficient (e.g., by helping users provide appropriate inputs and reducing user errors when operating / interacting with the device) through various techniques, including providing improved visual feedback to the user, reducing the number of inputs required to perform an action, providing additional control options without cluttering the user interface with additional controls, performing an action without requiring further user input when a set of conditions is met, improving privacy and / or security, providing a more diverse, detailed, and / or realistic user experience while saving storage space, and / or additional techniques. These techniques also reduce power usage and improve device battery life by allowing users to use the device more quickly and efficiently. Saving battery power, and therefore weight, improves device ergonomics. These techniques also enable real-time communication and the use of fewer and / or less accurate sensors, resulting in more compact, lighter, and less expensive devices, and allowing devices to be used in a variety of lighting conditions. These techniques reduce energy use and thereby reduce the heat given off by the device, which is particularly important for wearable devices where a device that is well within the operating parameters for the device components may become uncomfortable for the user to wear if it is generating too much heat.

[0034] Furthermore, for methods described herein in which one or more steps are conditioned on one or more conditions being satisfied, it should be understood that the described method can be repeated in multiple iterations, such that over the course of the iterations, all of the conditions on which the method steps are conditioned are satisfied in different iterations of the method. For example, if a method requires performing a first step if a condition is satisfied and a second step if the condition is not satisfied, one skilled in the art will understand that the steps recited in the claim are repeated in a particular order until the conditions are satisfied and then no longer satisfied. Thus, a method described with one or more steps that depend on one or more conditions being satisfied can be rewritten as a method that is repeated until each condition recited in the method is satisfied. However, this is not required for system or computer-readable medium claims in which the system or computer-readable medium includes instructions for performing a conditional action based on the satisfaction of the corresponding one or more conditions, and thus can determine whether a contingency is met without explicitly repeating the method steps until all conditions on which the method steps are conditioned are satisfied. Those skilled in the art will also understand that, as with methods having conditional steps, the system or computer-readable storage medium may repeat the steps of the method as many times as necessary to ensure that all of the conditional steps have been performed.

[0035] 1A , an XR experience is provided to a user via an operating environment 100 that includes a computer system 101. The computer system 101 includes a controller 110 (e.g., a processor of a portable electronic device or a remote server), a display generation component 120 (e.g., a head-mounted device (HMD), a display, a projector, a touchscreen, etc.), one or more input devices 125 (e.g., an eye-tracking device 130, a hand-tracking device 140, other input devices 150), one or more output devices 155 (e.g., a speaker 160, a tactile output generator 170, and other output devices 180), one or more sensors 190 (e.g., an image sensor, a light sensor, a depth sensor, a tactile sensor, an orientation sensor, a proximity sensor, a temperature sensor, a location sensor, a motion sensor, a speed sensor, etc.), and optionally one or more peripheral devices 195 (e.g., a consumer electronics device, a wearable device, etc.). In some embodiments, one or more of input device 125, output device 155, sensor 190, and peripheral device 195 are integrated with display generation component 120 (e.g., within a head-mounted or handheld device).

[0036] When describing an XR experience, various terms are used to individually refer to several related, but distinct, environments that a user can sense and / or interact with (e.g., using inputs detected by the computer system 101 generating the XR experience that cause the computer system generating the XR experience to generate audio, visual, and / or haptic feedback corresponding to various inputs provided to the computer system 101). The following is a subset of these terms:

[0037] Physical Environment: The physical environment refers to the physical world that people can sense and / or interact with without the aid of electronic systems. A physical environment, such as a physical park, includes physical objects such as physical trees, physical buildings, and physical people. People can directly sense and / or interact with the physical environment through their senses, such as sight, touch, hearing, taste, and smell.

[0038] Extended reality: In contrast, an extended reality (XR) environment refers to a wholly or partially simulated environment that people sense and / or interact with through electronic systems. In XR, a subset of a person's physical movements or representations thereof are tracked, and one or more properties of one or more virtual objects simulated within the XR environment are adjusted accordingly to behave according to at least one law of physics. For example, an XR system may detect a person's head rotation and accordingly adjust the graphical content and sound field presented to the person in a manner similar to how such views and sounds change in a physical environment. In some situations (e.g., for accessibility reasons), adjustments to a characteristic(s) of a virtual object(s) in an XR environment may be made in response to a representation of a physical movement (e.g., a voice command). A person may sense and / or interact with an XR object using any one of their senses, including sight, sound, touch, taste, and smell. For example, a person may sense and / or interact with audio objects that create a 3D or spatial audio environment that provides the perception of a point audio source in 3D space. In another example, audio objects may enable audio transparency that selectively incorporates ambient sounds from the physical environment, with or without computer-generated audio. In some XR environments, a person may sense and / or interact with only audio objects.

[0039] Examples of XR include virtual reality and mixed reality.

[0040] Virtual Reality: A virtual reality (VR) environment refers to a simulated environment designed to be based entirely on computer-generated sensory input for one or more senses. A VR environment includes multiple virtual objects that a person can sense and / or interact with. For example, computer-generated images of trees, buildings, and avatars representing people are examples of virtual objects. A person can sense and / or interact with virtual objects in a VR environment through a simulation of the person's presence in the computer-generated environment and / or through a simulation of a subset of the person's physical movement within the computer-generated environment.

[0041] Mixed reality: A mixed reality (MR) environment refers to a simulated environment designed to incorporate sensory input from or representations of a physical environment in addition to including computer-generated sensory input (e.g., virtual objects), as opposed to a VR environment designed to be based entirely on computer-generated sensory input. On a virtual continuum, a mixed reality environment is anywhere between, but not including, a complete physical environment at one end and a virtual reality environment at the other. In some MR environments, computer-generated sensory input may respond to changes in sensory input from the physical environment. Some electronic systems for presenting MR environments may also track location and / or orientation relative to the physical environment to allow virtual objects to interact with real objects (i.e., physical items from the physical environment or representations thereof). For example, the system may take into account movement so that a virtual tree appears stationary relative to the physical ground.

[0042] Examples of mixed reality include extended reality and augmented virtuality.

[0043] Extended Reality: An augmented reality (AR) environment refers to a simulated environment in which one or more virtual objects are superimposed on a physical environment or a representation thereof. For example, an electronic system for presenting an AR environment may have a transparent or translucent display through which a person can directly view the physical environment. The system may be configured to present virtual objects on the transparent or translucent display, whereby a person using the system perceives the virtual objects superimposed on the physical environment. Alternatively, the system may have an opaque display and one or more imaging sensors that capture images or videos of the physical environment that are representations of the physical environment. The system composites the images or videos with the virtual objects and presents the composite on the opaque display. The person uses the system to indirectly view the physical environment through the images or videos of the physical environment and perceive the virtual objects superimposed on the physical environment. As used herein, video of a physical environment shown on an opaque display is referred to as "pass-through video," meaning that the system captures images of the physical environment using one or more image sensors and uses those images in presenting the AR environment on the opaque display. Alternatively, the system may include a projection system that projects virtual objects, e.g., as holograms, into the physical environment or onto a physical surface, such that a person using the system perceives the virtual objects superimposed on the physical environment. An extended reality environment also refers to a simulated environment in which a representation of the physical environment is transformed by computer-generated sensory information. For example, in providing pass-through video, the system may distort one or more sensor images to impose a selected perspective (e.g., viewpoint) that differs from the perspective captured by the imaging sensor. As another example, the representation of the physical environment may be distorted by graphically modifying (e.g., enlarging) a portion thereof, such that the modified portion becomes a non-photorealistic, altered version that represents the originally captured image.As a further example, the representation of the physical environment may be altered by graphically removing or obscuring portions of it.

[0044] Augmented Virtuality: An augmented virtuality (AV) environment refers to a simulated environment in which a virtual or computer-generated environment incorporates one or more sensory inputs from a physical environment. The sensory inputs may be representations of one or more characteristics of the physical environment. For example, an AV park may have virtual trees and virtual buildings, while people with faces are realistically recreated from images taken of physical people. As another example, virtual objects may adopt the shape or color of physical items imaged by one or more imaging sensors. As a further example, virtual objects may adopt shadows that match the position of the sun in the physical environment.

[0045] In an augmented reality, mixed reality, or virtual reality environment, a view of a three-dimensional environment is visible to a user. The view of the three-dimensional environment is typically visible to a user via one or more display generating components (e.g., a display or pair of display modules providing stereoscopic content to different eyes of the same user) through a virtual viewport having a viewport boundary that defines the extent of the three-dimensional environment visible to the user via the one or more display generating components. In some embodiments, the area defined by the viewport boundary is smaller in one or more dimensions than the user's field of view (e.g., based on the user's field of view, the size, optical properties, or other physical characteristics of the one or more display generating components, and / or the location and / or orientation of the one or more display generating components relative to the user's eyes). In some embodiments, the area defined by the viewport boundary is larger in one or more dimensions than the user's field of view (e.g., based on the user's field of view, the size, optical properties, or other physical characteristics of the one or more display generating components, and / or the location and / or orientation of the one or more display generating components relative to the user's eyes). The viewport and viewport boundaries typically move as one or more display-generating components move (e.g., with the user's head in the case of a head-mounted device, or with the user's hands in the case of a handheld device such as a tablet or smartphone). The user's viewpoint determines what content is visible within the viewport; the viewpoint generally specifies a location and orientation relative to the three-dimensional environment; as the viewpoint shifts, the view of the three-dimensional environment also shifts within the viewport. In the case of a head-mounted device, the viewpoint is typically based on the location and orientation of the user's head, face, and / or eyes to provide a view of the three-dimensional environment that is perceptually accurate and provides an immersive experience when the user is using the head-mounted device.In the case of a handheld or stationary device, the viewpoint shifts as the handheld or stationary device is moved and / or as the user's position relative to the handheld or stationary device changes (e.g., as the user moves toward, away from, above, below, to the right of, and / or to the left of the device). In a device that includes a display generation component with virtual pass-through, the portion of the physical environment that is visible (e.g., displayed and / or projected) through one or more display generation components typically moves with the display generation components (e.g., moves with the user's head in a head-mounted device, or moves with the user's hand in a handheld device such as a tablet or smartphone) as the user's viewpoint moves as the field of view of one or more cameras moves (and the appearance of one or more virtual objects displayed through the one or more display generation components is updated based on the user's viewpoint (e.g., the displayed position and pose of the virtual objects are updated based on the movement of the user's viewpoint). In the case of display generating components that have an optical pass-through, the portion of the physical environment that is visible through one or more display generating components (e.g., optically visible through one or more partially or fully transparent portions of the display generating components) is based on the user's view through the partially or fully transparent portions of the display generating components (e.g., moves with the user's head in the case of a head-mounted device, or moves with the user's hand in the case of a handheld device such as a tablet or smartphone), such that the user's viewpoint moves (and the appearance of the one or more virtual objects is updated based on the user's viewpoint) as the user's viewpoint moves through the partially or fully transparent portion(s) of the display generating components.

[0046] In some embodiments, a representation of the physical environment (e.g., displayed via a virtual pass-through or optical pass-through) can be partially or completely obscured by the virtual environment. In some embodiments, the amount of the virtual environment that is displayed (e.g., the amount of the physical environment that is not displayed) is based on the immersion level of the virtual environment (e.g., relative to the representation of the physical environment). For example, increasing the immersion level optionally causes more of the virtual environment to be displayed, replacing and / or obscuring more of the physical environment, and decreasing the immersion level optionally causes less of the virtual environment to be displayed, revealing portions of the physical environment that were not previously displayed and / or obscured. In some embodiments, at a particular immersion level, one or more first background objects (e.g., in the representation of the physical environment) are visually less highlighted (e.g., dimmed, blurred, and / or displayed with increased transparency) than one or more second background objects, and one or more third background objects are discontinued. In some embodiments, the immersion level includes the relative degree to which the virtual content (e.g., the virtual environment and / or virtual content) displayed by the computer system obscures background content (e.g., content other than the virtual environment and / or virtual content) around / behind the virtual content, and optionally includes the number of items of background content displayed and / or the visual characteristics (e.g., color, contrast, and / or opacity) with which the background content is displayed, the angular range of the virtual content displayed via the display generating components (e.g., 60-degree content displayed in low immersion, 120-degree content displayed in medium immersion, or 180-degree content displayed in high immersion), and / or the percentage of the field of view displayed via the display generating components that is consumed by the virtual content (e.g., 33% of the field of view consumed by the virtual content in low immersion, 66% of the field of view consumed by the virtual content in medium immersion, or 100% of the field of view consumed by the virtual content in high immersion). In some embodiments, the background content is included in the background against which the virtual content is displayed (e.g., background content within a representation of the physical environment).In some embodiments, background content includes user interfaces (e.g., user interfaces generated by a computer system corresponding to an application), virtual objects (e.g., files or representations of other users generated by a computer system) that are not associated with or included in the virtual environment and / or virtual content, and / or real objects (e.g., pass-through objects that represent real objects in the physical environment around the user that are visible as displayed through the display generating components and / or that are visible through transparent or translucent components of the display generating components because the computer system does not obscure / prevent their visibility through the display generating components). In some embodiments, at a low immersion level (e.g., a first immersion level), the background, virtual, and / or real objects are displayed in an unobscured manner. For example, a virtual environment at a low immersion level is optionally displayed simultaneously with background content, and the background content is optionally displayed at full brightness, color, and / or translucency. In some embodiments, at a higher immersion level (e.g., a second immersion level higher than the first immersion level), the background, virtual, and / or real objects are displayed in an obscured manner (e.g., dimmed, blurred, or removed from the display). For example, a separate virtual environment having a high immersion level is displayed without simultaneously displaying background content (e.g., in a full-screen or fully immersive mode). As another example, a virtual environment displayed at an intermediate immersion level is simultaneously displayed with dimmed, blurred, or otherwise de-highlighted background content. In some embodiments, the visual characteristics of the background objects differ among the background objects. For example, at a particular immersion level, one or more first background objects are visually less highlighted (e.g., dimmed, blurred, and / or displayed with increased transparency) than one or more second background objects, and one or more third background objects are discontinued.In some embodiments, a null or zero immersion level corresponds to ceasing to display the virtual environment, and instead displaying a representation of the physical environment (optionally along with one or more virtual objects, such as applications, windows, or virtual three-dimensional objects) without the representation of the physical environment being obscured by the virtual environment. Adjusting immersion level using physical input elements provides a fast and efficient way to adjust immersion, improving usability of computer systems and making user-device interfaces more efficient.

[0047] Perspective-Locked Virtual Object: A virtual object is perspective-locked when the computer system displays the virtual object in the same location and / or position within the user's perspective, even as the user's perspective shifts (e.g., changes). In embodiments in which the computer system is a head-mounted device, the user's perspective is locked to the forward-facing orientation of the user's head (e.g., the user's perspective is at least a portion of the user's field of view when the user is looking straight ahead). Thus, the user's perspective remains fixed even as the user's line of sight moves without moving the user's head. In embodiments in which the computer system has a display generating component (e.g., a display screen) that can be repositioned relative to the user's head, the user's perspective is the augmented reality view being presented to the user on the display generating component of the computer system. For example, a perspective-locked virtual object that is displayed in the upper left corner of the user's perspective when the user's perspective is in a first orientation (e.g., the user's head is facing north) continues to be displayed in the upper left corner of the user's perspective when the user's perspective changes to a second orientation (e.g., the user's head is facing west). In other words, the location and / or position at which a viewpoint-locked virtual object is displayed in a user's viewpoint is independent of the user's position and / or orientation in the physical environment. In embodiments in which the computer system is a head-mounted device, the user's viewpoint is locked to the orientation of the user's head, such that the virtual object is also referred to as a "head-locked virtual object."

[0048] Environment-Locked Virtual Object: A virtual object is environment-locked (or "world-locked") when a computer system displays the virtual object at a location and / or position within a user's viewpoint that is based on (e.g., selected with reference to and / or anchored to) locations and / or objects within a three-dimensional environment (e.g., a physical environment or a virtual environment). As the user's viewpoint shifts, the locations and / or objects within the environment relative to the user's viewpoint change, resulting in the environment-locked virtual object appearing at a different location and / or position within the user's viewpoint. For example, an environment-locked virtual object locked to a tree directly in front of the user will appear centered within the user's viewpoint. If the user's viewpoint shifts to the right (e.g., the user's head is turned to the right) and the tree becomes more left-leaning in the user's viewpoint (e.g., the position of the tree in the user's viewpoint shifts), the environment-locked virtual object locked to the tree will appear more left-leaning in the user's viewpoint. In other words, the location and / or position at which the environment-locked virtual object appears within the user's viewpoint depends on the position and / or orientation of the location and / or object in the environment to which the virtual object is locked. In some embodiments, the computer system uses a stationary reference frame (e.g., a coordinate system fixed to a fixed location and / or object in the physical environment) to determine a position at which to display an environment-locked virtual object in the user's viewpoint. The environment-locked virtual object can be locked to a stationary portion of the environment (e.g., a floor, wall, table, or other stationary object) or can be locked to a moving portion of the environment (e.g., a vehicle, an animal, a person, or a representation of a part of the user's body that moves independent of the user's viewpoint, such as the user's hand, wrist, arm, or leg), so that the virtual object moves as the viewpoint or part of the environment moves in order to maintain a fixed relationship between the virtual object and the part of the environment.

[0049] In some embodiments, an environment-locked or viewpoint-locked virtual object exhibits delayed-following behavior, which reduces or delays the movement of the environment-locked or viewpoint-locked virtual object relative to the movement of a reference point that the virtual object is following. In some embodiments, when exhibiting delayed-following behavior, the computer system intentionally delays the movement of the virtual object when it detects movement of the reference point that the virtual object is following (e.g., a part of the environment, the viewpoint, or a point fixed relative to the viewpoint, such as a point between 5 and 300 cm from the viewpoint). For example, when the reference point (e.g., a part of the environment or the viewpoint) moves at a first speed, the virtual object is moved by the device to remain locked to the reference point, but at a second speed that is slower than the first speed (e.g., until the reference point stops or slows down, at which point the virtual object begins to catch up with the reference point). In some embodiments, when the virtual object exhibits delayed-following behavior, the device ignores small amounts of movement of the reference point (e.g., ignores movement of the reference point that is less than a threshold amount, such as movement between 0 and 5 degrees or movement between 0 and 50 cm). For example, when the reference point (e.g., a portion of the environment or a viewpoint to which the virtual object is locked) moves by a first amount, the distance between the reference point and the virtual object increases (e.g., because the virtual object is displayed to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and when the reference point (e.g., a portion of the environment or a viewpoint to which the virtual object is locked) moves by a second amount greater than the first amount, the distance between the reference point and the virtual object initially increases (e.g., because the virtual object is displayed to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and then decreases as the amount of movement of the reference point increases beyond a threshold (e.g., a “delayed following” threshold) as the virtual object is moved by the computer system to maintain a fixed or substantially fixed position relative to the reference point.In some embodiments, a virtual object maintaining a substantially fixed position relative to a reference point includes the virtual object being displayed within a threshold distance (e.g., 1, 2, 3, 5, 15, 20, 50 cm) of the reference point in one or more dimensions (e.g., above / below, left / right, and / or forward / backward relative to the position of the reference point).

[0050] Hardware: There are many different types of electronic systems that allow a person to sense and / or interact with various XR environments. Examples include head-mounted systems, projection-based systems, head-up displays (HUDs), vehicle windshields with integrated display capabilities, windows with integrated display capabilities, displays formed as lenses designed to be placed over a person's eyes (e.g., contact lenses), headphones / earphones, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablets, and desktop / laptop computers. A head-mounted system may have one or more speaker(s) and an integrated opaque display. Alternatively, a head-mounted system may be configured to accept an external opaque display (e.g., a smartphone). A head-mounted system may incorporate one or more imaging sensors for capturing images or video of the physical environment and / or one or more microphones for capturing audio of the physical environment. A head-mounted system may have a transparent or translucent display rather than an opaque display. A transparent or translucent display may have a medium through which light representing an image is directed toward a person's eyes. The display may utilize digital light projection, OLED, LED, uLED, liquid crystal on silicon, laser-scanned light source, or any combination of these technologies. The medium may be a light guide, a holographic medium, an optical combiner, an optical reflector, or any combination thereof. In one embodiment, the transparent or translucent display may be configured to be selectively opaque. A projection-based system may employ retinal projection technology that projects graphical images onto a person's retina. The projection system may also be configured to project virtual objects into the physical environment, for example, as holograms or onto physical surfaces. In some embodiments, the controller 110 is configured to manage and coordinate the XR experience for the user.In some embodiments, controller 110 includes a suitable combination of software, firmware, and / or hardware. Controller 110 is described in more detail below with reference to FIG. 2. In some embodiments, controller 110 is a computing device that is local or remote to scene 105 (e.g., the physical environment). For example, controller 110 is a local server located within scene 105. In another example, controller 110 is a remote server (e.g., a cloud server, a central server, etc.) located outside scene 105. In some embodiments, controller 110 is communicatively coupled to display generation component 120 (e.g., an HMD, a display, a projector, a touchscreen, etc.) via one or more wired or wireless communication channels 144 (e.g., BLUETOOTH, IEEE 802.11x, IEEE 802.16x, IEEE 802.3x, etc.). In another example, the controller 110 is contained within the housing (e.g., physical housing) of one or more of the display generating component 120 (e.g., an HMD or a portable electronic device including a display and one or more processors), one or more of the input devices 125, one or more of the output devices 155, one or more of the sensors 190, and / or one or more of the peripheral devices 195, or shares the same physical housing or support structure as one or more of the foregoing.

[0051] In some embodiments, display generation component 120 is configured to provide an XR experience (e.g., at least a visual component of the XR experience) to a user. In some embodiments, display generation component 120 includes a suitable combination of software, firmware, and / or hardware. Display generation component 120 is described in more detail below with reference to FIG. 3. In some embodiments, the functionality of controller 110 is provided by and / or combined with display generation component 120.

[0052] According to some embodiments, the display generation component 120 provides an XR experience to the user while the user is virtually and / or physically present in the scene 105.

[0053] In some embodiments, the display generating component is worn on a part of the user's body (e.g., on their head, their hand, etc.). Thus, display generating component 120 includes one or more XR displays provided for displaying XR content. For example, in various embodiments, display generating component 120 surrounds the user's field of view. In some embodiments, display generating component 120 is a handheld device (e.g., a smartphone or tablet) configured to present XR content, where the user holds the device with a display pointed toward the user's field of view and a camera pointed toward scene 105. In some embodiments, the handheld device is optionally located within a housing worn on the user's head. In some embodiments, the handheld device is optionally located on a support (e.g., a tripod) in front of the user. In some embodiments, display generating component 120 is an XR chamber, housing, or room configured to present XR content without the user wearing or holding display generating component 120. Many user interfaces described with reference to one type of hardware for displaying XR content (e.g., a handheld device or a device on a tripod) may be implemented on another type of hardware for displaying XR content (e.g., an HMD or other wearable computing device). For example, a user interface illustrating interactions with XR content that are triggered based on interactions occurring in the space in front of a handheld or tripod-mounted device may be implemented similarly to an HMD in which the interactions occur in the space in front of the HMD and the XR content responses are displayed via the HMD. Similarly, a user interface illustrating interactions with XR content that are triggered based on movement of a handheld or tripod-mounted device relative to the physical environment (e.g., scene 105 or a part of the user's body (e.g., the user's eye(s), head, or hands)) may be implemented similarly to an HMD in which the movement is caused by movement of the HMD relative to the physical environment (e.g., scene 105 or a part of the user's body (e.g., the user's eye(s), head, or hands)).

[0054] While relevant features of operating environment 100 are shown in FIG. 1A , those skilled in the art will understand from this disclosure that various other features are not shown for the sake of brevity so as not to obscure more pertinent aspects of the exemplary embodiments disclosed herein.

[0055] 1A-1P illustrate various examples of computer systems that can be used to perform the methods and provide audio, visual, and / or haptic feedback as part of the user interfaces described herein. In some embodiments, the computer system optionally includes one or more display generation components (e.g., first and second display assemblies 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a and 11.1.1-104b) for displaying representations of virtual elements and / or the physical environment to a user of the computer system, the representations being generated based on detected events and / or user input detected by the computer system. The user interface generated by the computer system is optionally corrected by one or more corrective lenses 11.3.2-216, optionally removably attached to one or more of the optical modules, to enable users who otherwise correct their vision using glasses or contact lenses to more easily view the user interface. While many user interfaces shown herein show a single view of the user interface, the user interface in the HMD is optionally displayed using two optical modules (e.g., first and second display assemblies 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a and 11.1.1-104b), one for the user's right eye and a different one for the user's left eye, with slightly different images presented to the two different eyes to create the illusion of stereoscopic depth, and the single view of the user interface is typically either a right-eye or left-eye view, and the depth effect is explained in text or using other schematic diagrams or views.In some embodiments, the computer system includes one or more external displays (e.g., display assembly 1-108) for displaying status information of the computer system to a user of the computer system (when the computer system is not being worn) and / or other people near the computer system, optionally generated based on detected events and / or user input detected by the computer system. In some embodiments, the computer system includes one or more audio output components (e.g., electronic components 1-112) for generating audio feedback, optionally generated based on detected events and / or user input detected by the computer system. In some embodiments, the computer system includes one or more input devices for detecting inputs, such as one or more sensors (e.g., sensor assembly 1-356 and / or one or more sensors in FIG. 1I) for detecting information about the physical environment of a device that can be used (optionally in conjunction with one or more illuminators, such as the illuminators described in FIG. 1I) to generate a digital pass-through image, capture visual media (e.g., photographs and / or videos) corresponding to the physical environment, or determine the pose (e.g., position and / or orientation) of physical objects and / or surfaces within the physical environment, so that virtual objects can be positioned based on the detected pose of the physical objects and / or surfaces. In some embodiments, the computer system includes one or more input devices for detecting input, such as one or more sensors for detecting hand position and / or movement (e.g., sensor assembly 1-356 and / or one or more sensors in FIG. 1I), which can be used (optionally in conjunction with one or more illuminators, such as illuminator 6-124 shown in FIG. 1I) to determine when one or more air gestures are performed.In some embodiments, the computer system includes one or more input devices for detecting input, such as one or more sensors for detecting eye movement (e.g., the eye tracking and gaze tracking sensors of FIG. 1I ), which may be used (optionally in conjunction with one or more lights, such as light 11.3.2-110 of FIG. 1O ) to determine attention or gaze position and / or gaze movement, which may optionally be used to detect gaze-only input based on gaze movement and / or dwell. A combination of the various sensors described above may be used to determine a user's facial expressions and / or hand movements for use in generating an avatar or representation of the user, such as an anthropomorphic avatar or representation for use in a real-time communication session, the avatar having facial expressions, hand movements, and / or body movements based on or similar to the detected facial expressions, hand movements, and / or body movements of the user of the device. Gaze and / or attention information is optionally combined with hand tracking information to determine interactions between the user and one or more user interfaces based on direct and / or indirect inputs, such as air gestures or inputs using one or more hardware input devices, such as one or more buttons (e.g., first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328), knobs (e.g., first button 1-128, button 11.1.1-114, and / or dial or button 1-328), digital crowns (e.g., pressable and twistable or rotatable first button 1-128, button 11.1.1-114, and / or dial or button 1-328), trackpads, touchscreens, keyboards, mice, and / or other input devices.One or more buttons (e.g., first button 1-128, button 11.1.1-114, second button 1-132, and / or dial or button 1-328) are optionally used to perform system operations such as re-centering content within the three-dimensional environment visible to the device user, displaying a home user interface for launching an application, initiating a real-time communication session, or initiating the display of a virtual three-dimensional background. The knob or digital crown (e.g., a first button 1-128, button 11.1.1-114, and / or a dial or button 1-328 that is depressible and twistable or rotatable) is optionally rotatable to adjust parameters of the visual content, such as the immersion level of the virtual three-dimensional environment (e.g., the degree to which the virtual content occupies the user's viewport into the three-dimensional environment), or other parameters associated with the three-dimensional environment and the virtual content displayed via the optical modules (e.g., first and second display assemblies 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a and 11.1.1-104b).

[0056] 1B illustrates a front, top, and perspective view of an example head-mountable display (HMD) device 1-100 configured to be worn by a user and provide virtual and altered / mixed reality (VR / AR) experiences. The HMD 1-100 can include a display unit 1-102 or assembly, an electronic strap assembly 1-104 connected to and extending from the display unit 1-102, and a band assembly 1-106 secured at either end to the electronic strap assembly 1-104. The electronic strap assembly 1-104 and band 1-106 can be part of a retention assembly configured to wrap around a user's head to hold the display unit 1-102 against the user's face.

[0057] In at least one example, the band assembly 1-106 can include a first band 1-116 configured to wrap around the back of the user's head and a second band 1-117 configured to extend over the top of the user's head. The second strap can extend between the first electronic strap 1-105a and the second electronic strap 1-105b of the electronic strap assembly 1-104, as shown. The strap assembly 1-104 and the band assembly 1-106 can be part of a fastening mechanism that extends rearward from the display unit 1-102 and is configured to hold the display unit 1-102 against the user's face.

[0058] In at least one example, the anchoring mechanism includes a first electronics strap 1-105a including a first proximal end 1-134 coupled to the display unit 1-102, e.g., a housing 1-150 of the display unit 1-102, and a first distal end 1-136 opposite the first proximal end 1-134. The anchoring mechanism can also include a second electronics strap 1-105b including a second proximal end 1-138 coupled to the housing 1-150 of the display unit 1-102, and a second distal end 1-140 opposite the second proximal end 1-138. The anchoring mechanism can also include a first band 1-116 including a first end 1-142 coupled to the first distal end 1-136 and a second end 1-144 coupled to the second distal end 1-140, and a second band 1-117 extending between the first electronic strap 1-105a and the second electronic strap 1-105b. The straps 1-105a-b and the band 1-116 can be coupled via a connection mechanism or assembly 1-114. In at least one example, the second band 1-117 includes a first end 1-146 coupled to the first electronic strap 1-105a between a first proximal end 1-134 and a first distal end 1-136, and a second end 1-148 coupled to the second electronic strap 1-105b between a second proximal end 1-138 and a second distal end 1-140.

[0059] In at least one example, the first and second electronic straps 1-105a-b include plastic, metal, or other structural material that forms the shape of the substantially rigid straps 1-105a-b. In at least one example, the first and second bands 1-116, 1-117 are formed from a resilient, flexible material including woven fabric, rubber, etc. The first and second bands 1-116, 1-117 can be flexible to conform to the shape of a user's head when wearing the HMD 1-100.

[0060] In at least one example, one or more of the first and second electronic straps 1-105a-b can define an internal strap volume and can include one or more electronic components disposed within the internal strap volume. In one example, as shown in FIG. 1B, the first electronic strap 1-105a can include an electronic component 1-112. In one example, the electronic component 1-112 can include a speaker. In one example, the electronic component 1-112 can include a computing component such as a processor.

[0061] In at least one example, the housing 1-150 defines a first, forward-facing opening 1-152. The display assembly 1-108 is disposed to block the first opening 1-152 from view when the HMD 1-100 is assembled, and therefore the forward-facing opening is labeled 1-152 with a dotted line in FIG. 1B . The housing 1-150 may also define a rear-facing second opening 1-154. The housing 1-150 also defines an interior volume between the first opening 1-152 and the second opening 1-154. In at least one example, the HMD 1-100 includes a display assembly 1-108, which may include a front cover and a display screen (shown in other figures) disposed within or across the front opening 1-152 to block the front opening 1-152. In at least one example, the display screen of the display assembly 1-108, as well as the entire display assembly 1-108, has a curvature configured to follow the curvature of the user's face. The display screen of the display assembly 1-108 can curve to complement the user's facial features and the overall curvature from one side of the face to the other, e.g., from left to right and / or top to bottom when the display unit 1-102 is pressed, as shown.

[0062] In at least one example, the housing 1-150 can define a first opening 1-126 between the first opening 1-152 and the second opening 1-154, and a second opening 1-130 between the first opening 1-152 and the second opening 1-154. The HMD 1-100 can also include a first button 1-128 disposed in the first opening 1-126 and a second button 1-132 disposed in the second opening 1-130. The first and second buttons 1-128, 1-132 can be depressible through the respective openings 1-126, 1-130. In at least one example, the first button 1-126 and / or the second button 1-132 can be a twistable dial and a depressible button. In at least one example, the first button 1-128 is a depressible and twistable dial button, and the second button 1-132 is a depressible button.

[0063] FIG. 1C shows a rear perspective view of the HMD 1-100. The HMD 1-100 can include a light seal 1-110 extending rearward from a housing 1-150 of the display assembly 1-108 around the periphery of the housing 1-150, as shown. The light seal 1-110 can be configured to extend from the housing 1-150 to the user's face around the user's eyes to block external light from being seen.

The adhesive layer 3-106 can bond the shroud 3-104 and / or the transparent cover 3-102 to the display assembly 3-108 and / or the trim 3-112. The trim 3-112 can bond various components of the front cover assembly 3-100 to the frame or chassis of the HMD device.

[0077] In at least one example, as shown in FIG. 1G, a display assembly 3-108 including a transparent cover 3-102, a shroud 3-104, and a lenticular lens array 3-110 can be curved to accommodate the curvature of a user's face. The transparent cover 3-102 and the shroud 3-104 can be curved in two or three dimensions, for example, vertically in the Z direction in or out of the ZX plane and horizontally in the X direction in or out of the ZX plane. In at least one example, the display assembly 3-108 can include a display panel having pixels configured to project light through the lenticular lens array 3-110 and the shroud 3-104 and the transparent cover 3-102. The display assembly 3-108 can be curved in at least one direction, for example, horizontally, to accommodate the curvature of a user's face from one side (e.g., left side) to the other side (e.g., right side) of the face. In at least one example, shown and described in more detail in subsequent figures, each layer or component of the display assembly 3-108, which may include the lenticular lens array 3-110 and the display layer, can be curved horizontally in a similar or concentric manner to accommodate the curvature of the user's face.

[0078] In at least one example, the shroud 3-104 can include a transparent or translucent material through which the display assembly 3-108 projects light. In one example, the shroud 3-104 can include one or more opaque portions, such as opaque ink prints or other opaque film portions, on a rear surface of the shroud 3-104. The rear surface can be the surface of the shroud 3-104 that faces the user's eyes when the HMD device is worn. In at least one example, the opaque portion can be on a front surface of the shroud 3-104 opposite the rear surface. In at least one example, the one or more opaque portions of the shroud 3-104 can include a peripheral portion that visually obscures any components around the perimeter of the display screen of the display assembly 3-108. In this manner, the opaque portions of the shroud hide any other components, including electronic components, structural components, etc., of the HMD device that would otherwise be visible through the transparent or translucent cover 3-102 and / or shroud 3-104.

[0079] In at least one example, the shroud 3-104 can define one or more aperture transparent portions 3-120 through which sensors can transmit and receive signals. In one example, the portions 3-120 are apertures through which sensors can extend or transmit and receive signals. In one example, the portions 3-120 are transparent portions, or portions that are more transparent than the surrounding translucent or opaque portions of the shroud, through which sensors can transmit and receive signals through the shroud and through the transparent cover 3-102. In one example, the sensors can include a camera, an IR sensor, a LUX sensor, or any other visual or non-visual environmental sensor of the HMD device.

For clarity of illustration, FIG. 1I shows the components of the sensor system 6-102 unattached from and electrically uncoupled from other components.

[0085] In at least one example, the device can include one or more controllers having a processor configured to execute instructions stored on a memory component electrically coupled to the processor, the instructions including, or capable of being executed by, one or more algorithms for self-correcting the various camera angles and positions described herein over time with use as the initial position, angle, or orientation of the camera is bumped or distorted due to an unintentional drop event or other event.

[0086] In at least one example, the sensor system 6-102 can include one or more scene cameras 6-106. The system 6-102 can include two scene cameras 6-106 disposed on either side of the bridge or arch of the nose of the HMD device 6-100, such that each of the two cameras 6-102 approximately corresponds to the position of the user's left and right eyes behind the cover 6-103. In at least one example, the scene cameras 6-106 are oriented generally forward in the Y direction to capture images in front of the user while the HMD 6-100 is in use. In at least one example, the scene cameras are color cameras and provide images and content for MR video pass-through to a display screen facing the user's eyes when using the HMD device 6-100. The scene cameras 6-106 can also be used for environment and object reconstruction.

[0087] In at least one example, the sensor system 6-102 may include a first depth sensor 6-108 oriented generally forward in the Y direction. In at least one example, the first depth sensor 6-108 may be used for environment and object reconstruction and hand and body tracking of the user. In at least one example, the sensor system 6-102 may include a second depth sensor 6-110 centrally disposed along the width of the HMD device 6-100 (e.g., along the X axis). For example, the second depth sensor 6-110 may be positioned in alignment with the center bridge or feature above the user's nose when wearing the HMD 6-100. In at least one example, the second depth sensor 6-110 may be used for environment and object reconstruction and hand and body tracking. In at least one example, the second depth sensor may include a LIDAR sensor.

[0088] In at least one example, the sensor system 6-102 can include a generally forward-facing depth projector 6-112 for projecting electromagnetic waves, e.g., in the form of a predetermined pattern of light dots, into and within a field of view of, or including and beyond, the user and / or scene camera 6-106. In at least one example, the depth projector can project electromagnetic waves of light in the form of a dot light pattern that reflects off objects and returns to the depth sensors described above, including the depth sensors 6-108, 6-110. In at least one example, the depth projector 6-112 can be used for environment and object reconstruction and hand and body tracking.

[0089] In at least one example, the sensor system 6-102 may include downward-facing cameras 6-114 having fields of view directed generally downward relative to the HMD device 6-100 in the Z-axis. In at least one example, the downward-facing cameras 6-114 may be disposed on the left and right sides of the HMD device 6-100 as shown and may be used for hand and body tracking, headset tracking, and facial avatar detection and creation to display a user avatar on the forward-facing display screen of the HMD device 6-100 as described elsewhere herein. The downward-facing cameras 6-114 may be used to capture facial expressions and movements of the user below the HMD device 6-100, including, for example, the cheeks, mouth, and chin.

[0090] In at least one example, the sensor system 6-102 may include chin cameras 6-116. In at least one example, the chin cameras 6-116 are disposed on the left and right sides of the HMD device 6-100 as shown and may be used for hand and body tracking, headset tracking, and facial avatar detection and creation to display a user avatar on the forward-facing display screen of the HMD device 6-100 as described elsewhere herein. The chin cameras 6-116 may be used to capture the expressions and movements of the user's face below the HMD device 6-100, including, for example, the user's chin, cheeks, mouth, and jaw. For hand and body tracking, headset tracking, and facial avatar,

[0091] In at least one example, the sensor system 6-102 can include a side camera 6-118. The side camera 6-118 can be oriented to capture left and right side views in the X-axis or direction relative to the HMD device 6-100. In at least one example, the side camera 6-118 can be used for hand and body tracking, headset tracking, and facial avatar detection and reconstruction.

[0092] In at least one example, the sensor system 6-102 can include multiple eye tracking and gaze tracking sensors for determining the identity, status, and gaze direction of a user's eyes during and / or before use. In at least one example, the eye / gaze tracking sensors can include nose-eye cameras 6-120 disposed on either side of and adjacent to the user's nose when the HMD device 6-100 is worn. The eye / gaze sensors can also include under-eye cameras 6-122 disposed below each user's eye for capturing eye images for facial avatar detection and creation, gaze tracking, and iris identification functions.

[0093] In at least one example, the sensor system 6-102 includes an infrared illuminator 6-124 directed outward from the HMD device 6-100 to illuminate the external environment and any objects therein with IR light for IR detection by one or more IR sensors of the sensor system 6-102. In at least one example, the sensor system 6-102 can include a flicker sensor 6-126 and an ambient light sensor 6-128. In at least one example, the flicker sensor 6-126 can detect the overhead light refresh rate to avoid display flicker. In one example, the infrared illuminator 6-124 can include a light-emitting diode and can be used, among other things, in low-light environments to illuminate a user's hands and other objects in low light for detection by the infrared sensors of the sensor system 6-102.

[0094] In at least one example, multiple sensors including a scene camera 6-106, a downward-facing camera 6-114, a chin camera 6-116, a side camera 6-118, a depth projector 6-112, and depth sensors 6-108, 6-110 can be used in combination with an electrically coupled controller to combine depth data with camera data for hand tracking and sizing for better hand tracking and object recognition and tracking capabilities of the HMD device 6-100. In at least one example, the downward-facing camera 6-114, chin camera 6-116, and side camera 6-118 described above and shown in FIG. 1I can be wide-angle cameras capable of operating in the visible and infrared spectrum. In at least one example, these cameras 6-114, 6-116, 6-118 can operate with only black and white light detection to simplify image processing and increase sensitivity.

[0095] Any of the features, components, and / or parts shown in Figure 1I, including their arrangements and configurations, alone or in any combination, may be included in any of the other example devices, features, components, and parts shown in Figures 1J-1L and described herein. Similarly, any of the features, components, and / or parts shown and described with reference to Figures 1J-1L, including their arrangements and configurations, alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1I.

[0096] 1J shows a bottom perspective view of an example of an HMD 6-200 including a cover or shroud 6-204 secured to a frame 6-230. In at least one example, the sensors 6-203 of the sensor system 6-202 can be disposed around the periphery of the HDM 6-200 such that the sensors 6-203 are disposed outwardly around the periphery of the display region or area 6-232 so as not to obstruct the view of the displayed light. In at least one example, the sensors can be disposed behind the shroud 6-204 and aligned with a transparent portion of the shroud to allow the sensors and projector to pass light back and forth through the shroud 6-204. In at least one example, an opaque ink or other opaque material or film / layer can be disposed on the shroud 6-204 around the display area 6-232 to obscure components of the HMD 6-200 outside of the display area 6-232 other than the transparent portion defined by the opaque portion, through which the sensors and projector transmit and receive light and electromagnetic signals during operation. In at least one example, the shroud 6-204 allows light to pass through it from the display (e.g., within the display area 6-232), but not radially outward from the display area around the outer periphery of the shroud 6-204.

[0097] In some examples, the shroud 6-204 includes a transparent portion 6-205 and an opaque portion 6-207, as described above and elsewhere herein. In at least one example, the opaque portion 6-207 of the shroud 6-204 can define one or more transparent areas 6-209 through which the sensors 6-203 of the sensor system 6-202 can send and receive signals. In the illustrated example, the sensors 6-203 of the sensor system 6-202, which transmit and receive signals through the shroud 6-204, or more specifically through the transparent region 6-209 of (or defined by) the opaque portion 6-207 of the shroud 6-204, may include sensors the same as or similar to those shown in the example of FIG. 1I, such as depth sensors 6-108 and 6-110, a depth projector 6-112, first and second scene cameras 6-106, first and second downward-facing cameras 6-114, first and second side cameras 6-118, and first and second infrared illuminators 6-124.

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

[0100] In at least one example, the various sensors of the sensor system 6-302 are coupled to brackets 6-336, 6-338. In at least one example, the scene cameras 6-306 include tight tolerances on their angles relative to one another. For example, the tolerance on the mounting angle between the two scene cameras 6-306 can be 0.5 degrees or less, e.g., 0.3 degrees or less. To achieve and maintain such tight tolerances, in one example, the scene camera 6-306 can be mounted to the bracket 6-338 rather than the shroud. The bracket can include a cantilever arm to which the scene camera 6-306 and other sensors of the sensor system 6-302 can be mounted such that their position and orientation remain undeformed in the event of a drop event by the user that results in any deformation of the other brackets 6-226, the housing 6-330, and / or the shroud.

In at least one example, the button 11.1.1-114 is in electrical communication with the first and second motors 11.1.1-110a-b via a processor or other circuit components to activate the first and second motors 11.1.1-110a-b and cause the first and second optical modules 11.1.1-104a-b, respectively, to change position relative to one another.

[0105] In at least one example, the first and second optical modules 11.1.1-104a-b can include respective display screens configured to project light toward the user's eyes when wearing the HMD 11.1.1-100. In at least one example, the user can manipulate (e.g., press and / or rotate) the button 11.1.1-114 to actuate position adjustments of the optical modules 11.1.1-104a-b to match the interpupillary distance of the user's eyes. The optical modules 11.1.1-104a-b can also include one or more cameras or other sensors / sensor systems for imaging and measuring the user's IPD so that the optical modules 11.1.1-104a-b can be adjusted to match the IPD.

[0106] In one example, a user can actuate the button 11.1.1-114 to trigger an automatic position adjustment of the first and second optical modules 11.1.1-104a-b. In one example, a user can actuate the button 11.1.1-114 to trigger a manual adjustment, such as moving the optical modules 11.1.1-104a-b farther or closer together when the user rotates the button 11.1.1-114 in one direction or the other, until the user visually aligns their IPD. In one example, the manual adjustment is communicated electronically via one or more circuits, and power for movement of the optical modules 11.1.1-104a-b via the motors 11.1.1-110a-b is provided by a power source. In one example, the adjustment and movement of the optical modules 11.1.1-104a-b via actuation of the button 11.1.1-114 is mechanically actuated via movement of the button 11.1.1-114.

[0107] Any of the features, components, and / or parts shown in Figure 1M, including their arrangement and configuration, alone or in any combination, may be included in any of the other example devices, features, components, and parts shown in any other figure shown and described herein, as well as any of the features, components, and / or parts, including their arrangement and configuration, either alone or in any combination, shown and described with reference to any other figure shown and described herein.

[0108] FIG. 1N shows a front perspective view of a portion of an HMD 11.1.2-100, including an outer structural frame 11.1.2-102 and an inner or intermediate structural frame 11.1.2-104, which define first and second openings 11.1.2-106a, 11.1.2-106b. The openings 11.1.2-106a-b are shown with dashed lines in FIG. 1N because the view of the openings 11.1.2-106a-b may be obstructed by one or more other components of the HMD 11.1.2-100 coupled to the inner frame 11.1.2-104 and / or the outer frame 11.1.2-102, as shown. In at least one example, the HMD 11.1.2-100 can include a first mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104. In at least one example, a mounting bracket 11.1.2-108 is coupled to the inner frame 11.1.2-104 between the first and second openings 11.1.2-106a-b.

[0109] The mounting bracket 11.1.2-108 may include an intermediate or central portion 11.1.2-109 coupled to the inner frame 11.1.2-104. In some examples, the intermediate or central portion 11.1.2-109 may not be the geometric middle or center of the bracket 11.1.2-108. Rather, the intermediate / central portion 11.1.2-109 may be disposed between first and second cantilevered extension arms extending away from the intermediate portion 11.1.2-109. In at least one example, the mounting bracket 108 includes first and second cantilevered arms 11.1.2-112 and 11.1.2-114 extending away from the intermediate portion 11.1.2-109 of the mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104.

[0110] As shown in FIG. 1N, the outer frame 11.1.2-102 can define a curved shape on its underside to accommodate a user's nose when the user is wearing the HMD 11.1.2-100. The curved shape can be referred to as a nose bridge 11.1.2-111 and can be centrally located on the underside of the HMD 11.1.2-100 as shown. In at least one example, the mounting bracket 11.1.2-108 can be connected to the inner frame 11.1.2-102 between the openings 11.1.2-106a-b such that the cantilevered arms 11.1.2-112, 11.1.2-114 extend downward and laterally outward away from the intermediate portion 11.1.2-109 to complement the shape of the nose bridge 11.1.2-111 of the outer frame 11.1.2-104. In this manner, the mounting bracket 11.1.2-108 is configured to accommodate the user's nose as described above. The shape of the nose bridge 11.1.2-111 accommodates the nose in that the nose bridge 11.1.2-111 provides a curvature that curves with, over, on and around the user's nose for comfort and fit.

[0111] The first cantilevered arm 11.1.2-112 can extend in a first direction away from the intermediate portion 11.1.2-109 of the mounting bracket 11.1.2-108, and the second cantilevered arm 11.1.2-114 can extend in a second direction opposite the first direction away from the intermediate portion 11.1.2-109 of the mounting bracket 11.1.2-10. The first and second cantilevered arms 11.1.2-112, 11.1.2-114 are referred to as "cantilevered" or "cantilever" arms because each arm 11.1.2-112, 11.1.2-114 includes a distal free end 11.1.2-116, 11.1.2-118, respectively, that is not secured to the inner and outer frames 11.1.2-102, 11.1.2-104. In this way, the arms 11.1.2-112, 11.1.2-114 are cantilevered from an intermediate section 11.1.2-109 which may be connected to the inner frame 11.1.2-104 with the distal ends 11.1.2-102, 11.1.2-104 unattached.

[0112] In at least one example, the HMD 11.1.2-100 can include one or more components coupled to the mounting bracket 11.1.2-108. In one example, the components include a plurality of sensors 11.1.2-110a-f. Each sensor of the plurality of sensors 11.1.2-110a-f can include various types of sensors, including cameras, IR sensors, etc. In some examples, one or more of the sensors 11.1.2-110a-f can be used for object recognition in three-dimensional space, such that maintaining accurate relative positions of two or more of the plurality of sensors 11.1.2-110a-f is important. The cantilevered nature of the mounting bracket 11.1.2-108 can protect the sensors 11.1.2-110a-f from damage and repositioning in the event of an accidental drop by the user. Because the sensors 11.1.2-110a-f are cantilevered onto the arms 11.1.2-112, 11.1.2-114 of the mounting bracket 11.1.2-108, stresses and deformations of the inner and / or outer frames 11.1.2-104, 11.1.2-102 are not transferred to the cantilevered arms 11.1.2-112, 11.1.2-114 and therefore do not affect the relative positioning of the sensors 11.1.2-110a-f coupled / attached to the mounting bracket 11.1.2-108.

[0113] Any of the features, components, and / or parts shown in Figure 1N, including their arrangement and configuration, alone or in any combination, may be included in any of the other example devices, features, and parts described herein. Similarly, any of the features, components, and / or parts shown and described herein, including their arrangement and configuration, alone or in any combination, may be included in the example devices, features, components, and parts shown in Figure 1N.

[0114] FIG. 10 illustrates an example of an optical module 11.3.2-100 for use in an electronic device, such as an HMD, including the HDM device described herein. As shown in one or more other examples described herein, optical module 11.3.2-100 may be one of two optical modules in an HMD, each aligned to project light toward a user's eye. In this manner, a first optical module can project light toward a first eye of a user through a display screen, and a second optical module of the same device can project light toward a second eye of the user through another display screen.

[0115] In at least one example, the optical module 11.3.2-100 can include an optical frame or housing 11.3.2-102, which can also be referred to as a barrel or optical module barrel. The optical module 11.3.2-100 can also include a display 11.3.2-104, including a display screen or multiple display screens, coupled to the housing 11.3.2-102. The display 11.3.2-104 can be coupled to the housing 11.3.2-102 such that the display 11.3.2-104 is configured to project light toward a user's eyes when the HMD of which the display module 11.3.2-100 is a part is worn during use. In at least one example, the housing 11.3.2-102 can surround the display 11.3.2-104 and provide a connection mechanism for coupling other components of the optical module described herein.

[0116] In one example, the optical module 11.3.2-100 may include one or more cameras 11.3.2-106 coupled to the housing 11.3.2-102. The cameras 11.3.2-106 may be positioned relative to the display 11.3.2-104 and the housing 11.3.2-102 such that the cameras 11.3.2-106 are configured to capture one or more images of a user's eyes during use. In at least one example, the optical module 11.3.2-100 may also include a light strip 11.3.2-108 surrounding the display 11.3.2-104. In one example, the light strip 11.3.2-108 is disposed between the display 11.3.2-104 and the camera 11.3.2-106. The light strip 11.3.2-108 may include a plurality of lights 11.3.2-110. The plurality of lights may include one or more light-emitting diodes (LEDs) or other lights configured to project light toward the user's eyes when the HMD is worn. The individual lights 11.3.2-110 of the light strip 11.3.2-108 may be spaced around the strip 11.3.2-108 and thus may be evenly or unevenly spaced around the display 11.3.2-104 at various locations on the strip 11.3.2-108 and around the display 11.3.2-104.

[0117] In at least one example, the housing 11.3.2-102 defines a viewing opening 11.3.2-101 through which a user can view the display 11.3.2-104 when the HMD device is worn. In at least one example, the LEDs are configured and arranged to emit light onto the user's eyes through the viewing opening 11.3.2-101. In one example, the camera 11.3.2-106 is configured to capture one or more images of the user's eyes through the viewing opening 11.3.2-101.

[0118] As mentioned above, each of the components and features of optical module 11.3.2-100 shown in FIG. 1O may be replicated in another (e.g., a second) optical module disposed with the HMD to interact with the user's other eye (e.g., project light and capture images).

[0120] 1P illustrates a cross-sectional view of an example optical module 11.3.2-200 including a housing 11.3.2-202, a display assembly 11.3.2-204 coupled to the housing 11.3.2-202, and a lens 11.3.2-216 coupled to the housing 11.3.2-202. In at least one example, the housing 11.3.2-202 defines a first opening or channel 11.3.2-212 and a second opening or channel 11.3.2-214. The channels 11.3.2-212, 11.3.2-214 may be configured to slidably engage respective rails or guide rods of an HMD device to enable the optical module 11.3.2-200 to be positioned relative to a user's eyes to match the user's inter-papillary distance (IPD). The housing 11.3.2-202 can slidably engage guide rods to secure the optical module 11.3.2-200 in place within the HMD.

The lens 11.3.2-216 may be configured to direct light from the display assembly 11.3.2-204 toward the user's eyes. In at least one example, the lens 11.3.2-216 may be part of a lens assembly that includes a corrective lens removably attached to the optical module 11.3.2-200. In at least one example, the lens 11.3.2-216 is disposed over the light strip 11.3.2-208 and one or more eye tracking cameras 11.3.2-206, such that the camera 11.3.2-206 is configured to capture images of the user's eyes through the lens 11.3.2-216, and the light strip 11.3.2-208 includes lights configured to project light into the user's eyes through the lens 11.3.2-216 during use.

[0143] Although the data acquisition unit 342, the XR presentation unit 344, the XR map generation unit 346, and the data transmission unit 348 are shown as residing on a single device (e.g., the display generation component 120 of FIG. 1A), it should be understood that in other embodiments, any combination of the data acquisition unit 342, the XR presentation unit 344, the XR map generation unit 346, and the data transmission unit 348 may be located within separate computing devices.

[0144] Furthermore, Figure 3 is intended more to illustrate the functionality of various features that may be present in particular implementations, as opposed to a structural overview of the embodiments described herein. As will be recognized by those skilled in the art, items shown separately can be combined and some items can be separated. For example, some functional modules shown separately in Figure 3 can be implemented within a single module, and various functions of a single functional block can be performed by one or more functional blocks in various embodiments. The actual number of modules, as well as the division of specific functions and how functions are allocated among them, will vary from implementation to implementation and, in some embodiments, will depend in part on the particular combination of hardware, software, and / or firmware selected for a particular implementation.

[0145] 4 is a schematic diagram of an example embodiment of hand tracking device 140. In some embodiments, hand tracking device 140 (FIG. 1A) is controlled by hand tracking unit 244 (FIG. 2) to track the position / location of one or more parts of a user's hand and / or the movement of one or more parts of a user's hand relative to scene 105 of FIG. 1A (e.g., relative to a portion of the physical environment surrounding the user, relative to display generating component 120, or relative to a portion of the user (e.g., the user's face, eyes, or head), and / or relative to the user's hand). In some embodiments, hand tracking device 140 is part of display generating component 120 (e.g., embedded in or attached to a head-mounted device). In some embodiments, hand tracking device 140 is separate from display generating component 120 (e.g., located in a separate housing or attached to a separate physical support structure).

[0146] In some embodiments, the hand tracking device 140 includes an image sensor 404 (e.g., one or more IR cameras, 3D cameras, depth cameras, and / or color cameras) that captures three-dimensional scene information including at least the hand 406 of a human user. The image sensor 404 captures hand images with sufficient resolution to allow for differentiation of the fingers and their respective positions. The image sensor 404 typically captures images of other parts of the user's body, or all of the body, and can have either zoom capabilities or a dedicated sensor with high magnification to capture hand images at a desired resolution. In some embodiments, the image sensor 404 also captures 2D color video images of the hand 406 and other elements of the scene. In some embodiments, the image sensor 404 is used in conjunction with or functions as an image sensor that captures the physical environment of the scene 105. In some embodiments, the image sensor 404 is positioned relative to the user or the user's environment such that the field of view of the image sensor, or a portion thereof, is used to define an interaction space in which hand movements captured by the image sensor are processed as inputs to the controller 110.

[0147] In some embodiments, image sensor 404 outputs a sequence of frames containing 3D map data (and possibly color image data) to controller 110, which extracts high-level information from the map data. This high-level information is typically provided via an application program interface (API) to an application running on the controller, which drives display generation component 120 accordingly. For example, a user can interact with software running on controller 110 by moving their hand 406 and changing the posture of their hand.

[0148] In some embodiments, the image sensor 404 projects a spot pattern onto a scene including the hand 406 and captures an image of the projected pattern. In some embodiments, the controller 110 calculates the 3D coordinates of points in the scene (including points on the surface of the user's hand) by triangulation based on the lateral shift of the spots of the pattern. This approach is advantageous in that it does not require the user to hold or wear any type of beacon, sensor, or other marker. This provides depth coordinates of points in the scene relative to a predetermined reference plane at a specific distance from the image sensor 404. In this disclosure, the image sensor 404 is assumed to define an orthogonal set of x, y, and z axes such that the depth coordinate of a point in the scene corresponds to the z component measured by the image sensor. Alternatively, the image sensor 404 (e.g., a hand tracking device) can use other 3D mapping methods, such as stereoscopic imaging or time-of-flight measurements, based on single or multiple cameras or other types of sensors.

[0149] In some embodiments, the hand tracking device 140 captures and processes a time sequence of depth maps containing the user's hand while the user moves the hand (e.g., the entire hand or one or more fingers). Software running on the image sensor 404 and / or a processor in the controller 110 processes the 3D map data to extract patch descriptors of the hand in these depth maps. The software matches these descriptors to patch descriptors stored in the database 408, based on a previous training process, to estimate the pose of the hand in each frame. The pose typically includes the 3D locations of the user's wrist joints and fingertips.

[0150] The software can also analyze hand and / or finger trajectories across multiple frames in a sequence to identify gestures. The pose estimation functionality described herein may be interleaved with motion tracking functionality, whereby patch-based pose estimation is performed only once every two (or more) frames, while tracking is used to discover pose changes that occur across the remaining frames. The pose, motion, and gesture information is provided to an application program running on controller 110 via the API described above. This program can, for example, move and modify an image presented on display generation component 120 or perform other functions in response to the pose and / or gesture information.

[0151] In some embodiments, the gesture includes an air gesture, which is detected without (or independent of) the user touching an input element that is part of a device (e.g., computer system 101, one or more input devices 125, and / or hand tracking device 140) and is based on detected movement of a part of the user's body in the air (e.g., head, one or more arms, one or more hands, one or more fingers, and / or one or more legs), including movement of the user's body relative to an absolute reference (e.g., the angle of the user's arm relative to the ground or the distance of the user's hand relative to the ground), movement of the user's body relative to another part of the user's body (e.g., movement of the user's hand relative to the user's shoulder, movement of one of the user's hands relative to another of the user's hands, and / or movement of a user's finger relative to another finger or part of the user's hand), and / or absolute movement of the user's body part (e.g., a tap gesture involving movement of a hand in a predetermined posture by a predetermined amount and / or speed, or a shake gesture involving a predetermined speed or amount of rotation of the user's body part).

[0152] In some embodiments, input gestures used in various examples and embodiments described herein include air gestures performed by movement of a user's finger(s) relative to other finger(s) or part(s) of the user's hand to interact with an XR environment (e.g., a virtual or mixed reality environment), according to some embodiments. In some embodiments, an air gesture is a gesture that is detected without the user touching an input element that is part of the device (or independent of an input element that is part of the device) and is based on detected movement of a part of the user's body in the air, including movement of the user's body relative to an absolute reference (e.g., the angle of the user's arm relative to the ground or the distance of the user's hand relative to the ground), movement of the user's body relative to another part of the user's body (e.g., movement of the user's hand relative to the user's shoulder, movement of the user's other hand relative to one of the user's hands, and / or movement of the user's fingers relative to another finger or part of the user's hand), and / or absolute movement of the user's body part (e.g., a tap gesture that includes movement of the hand in a predetermined pose by a predetermined amount and / or speed, or a shake gesture that includes rotation of the user's body part at a predetermined speed or amount).

[0153] In some embodiments where the input gesture is an air gesture (e.g., in the absence of physical contact with an input device that provides a computer system with information about which user interface element is the target of the user input, such as contact with a user interface element displayed on a touchscreen or contact with a mouse or trackpad to move a cursor to a user interface element), the gesture takes into account the user's attention (e.g., gaze) to determine the target of the user input (e.g., in the case of direct input, as described below). Thus, in implementations that include air gestures, the input gesture is detected attention (e.g., gaze) to a user interface element in combination with (e.g., simultaneous with) movement of the user's finger(s) and / or hand to perform pinch and / or tap input, as described in more detail below.

[0154] In some embodiments, an input gesture directed at a user interface object is performed directly or indirectly with reference to the user interface object. For example, user input is performed directly at a user interface object in response to performing an input gesture with the user's hand at a position corresponding to the user interface object's position in the three-dimensional environment (e.g., as determined based on the user's current viewpoint). In some embodiments, an input gesture is performed indirectly at a user interface object in response to detecting the user's attention (e.g., gaze) to the user interface object while performing the input gesture while the user's hand position is not at a position corresponding to the user interface object's position in the three-dimensional environment. For example, for a direct input gesture, a user can direct the user's input at a user interface object by initiating the gesture at or near a position corresponding to the user interface object's displayed position (e.g., within a distance of 0.5 cm, 1 cm, 5 cm, or 0-5 cm, measured from an outer edge of the option or a central portion of the option). For indirect input gestures, a user can direct their input to a user interface object by paying attention to the user interface object (e.g., by gazing at the user interface object), and while paying attention to the option, the user initiates an input gesture (e.g., at any position detectable by the computer system) (e.g., at a position that does not correspond to the displayed position of the user interface object).

[0155] In some embodiments, input gestures (e.g., air gestures) used in various examples and embodiments described herein include pinch inputs and tap inputs for interacting with a virtual or mixed reality environment, according to some embodiments. For example, pinch inputs and tap inputs, as described below, are performed as air gestures.

[0156] In some embodiments, the pinch input is part of an air gesture, including one or more of a pinch gesture, a long pinch gesture, a pinch-and-drag gesture, or a double pinch gesture. For example, a pinch gesture that is an air gesture includes moving two or more fingers of a hand to contact each other, i.e., optionally with a short break (e.g., within 0-1 second) after contact with each other. A long pinch gesture that is an air gesture includes moving two or more fingers of a hand to contact each other for at least a threshold amount of time (e.g., at least 1 second) before detecting a break in contact with each other. For example, a long pinch gesture includes a user holding a pinch gesture (e.g., when two or more fingers are in contact), and the long pinch gesture continues until a break in contact between the two or more fingers is detected. In some embodiments, a double pinch gesture that is an air gesture includes two (e.g., or more) pinch inputs (e.g., performed by the same hand) that are detected immediately in succession (e.g., within a predetermined period of time) after each other. For example, a user performs a first pinch input (e.g., a pinch input or a long pinch input), releases the first pinch input (e.g., breaking contact between two or more fingers), and performs a second pinch input within a predetermined period of time (e.g., within 1 second or 2 seconds) after releasing the first pinch input.

[0157] In some embodiments, a pinch-and-drag gesture that is an air gesture includes a pinch gesture (e.g., a pinch gesture or a long pinch gesture) performed in conjunction with (e.g., followed by) a drag input that changes the position of a user's hand from a first position (e.g., a start position of the drag) to a second position (e.g., an end position of the drag). In some embodiments, a user maintains the pinch gesture while performing the drag input and releases the pinch gesture (e.g., spreading two or more fingers apart) to end the drag gesture (e.g., at the second position). In some embodiments, the pinch input and the drag input are performed by the same hand (e.g., a user pinches two or more fingers together and moves the same hand to a second position in the air with a drag gesture). In some embodiments, the pinch input is performed by a user's first hand and the drag input is performed by the user's second hand (e.g., the user's second hand moves from a first position to a 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 an input (e.g., a pinch input and / or a tap input) performed using both of a user's hands. For example, the input gesture includes two (e.g., or more) pinch inputs performed in conjunction with each other (e.g., simultaneously or within a predetermined period of time). For example, a first pinch gesture (e.g., a pinch input, a long pinch input, or a pinch and drag input) performed using a first hand of the user and a second pinch input performed using the other hand (e.g., a second hand of the user's both hands) in conjunction with performing the pinch input using the first hand.

[0158] In some embodiments, a tap input (e.g., directed toward a user interface element) performed as an air gesture includes movement(s) of a user's finger(s) toward the user interface element, movement of a user's hand toward a user interface element, optionally with the user's finger(s) extended toward the user interface element, a downward movement of a user's finger (e.g., mimicking a mouse click action or a tap on a touchscreen), or other predefined movement of the user's hand. In some embodiments, a tap input performed as an air gesture is detected based on movement characteristics of the finger or hand performing the tap gesture, moving the finger or hand away from the user's viewpoint and / or toward the object that is the target of the tap input followed by an end of the movement. In some embodiments, an end of the movement is detected based on a change in movement characteristics of the finger or hand performing the tap gesture (e.g., an end of movement away from the user's viewpoint and / or toward the object that is the target of the tap input, a reversal of the direction of movement of the finger or hand, and / or a reversal of the direction of acceleration of the movement of the finger or hand).

[0159] In some embodiments, the user's attention is determined to be directed to a portion of the three-dimensional environment based on detecting a gaze directed to the portion of the three-dimensional environment (optionally, without requiring other conditions). In some embodiments, the device determines that the user's attention is directed to the portion of the three-dimensional environment based on detecting a gaze directed to the portion of the three-dimensional environment with one or more additional conditions, such as requiring the gaze to be directed to the portion of the three-dimensional environment for at least a threshold duration (e.g., dwell time) while the user's viewpoint is within a distance threshold from the portion of the three-dimensional environment, and / or requiring the gaze to be directed to the portion of the three-dimensional environment, and if one of the additional conditions is not met, the device determines that the user's attention is not directed to the portion of the three-dimensional environment to which the gaze is directed (e.g., until one or more additional conditions are met).

[0160] In some embodiments, detection of a ready configuration of a user or a portion of a user is detected by a computer system, and detection of a ready configuration of the hands is used by the computer system as an indication that the user is likely preparing to interact with the computer system using one or more air gesture inputs performed with the hands (e.g., pinch, tap, pinch and drag, double pinch, long pinch, or other air gestures described herein). For example, the ready state of a hand is determined based on whether the hand has a predetermined hand geometry (e.g., a pre-pinch geometry with the thumb and one or more fingers extended and spaced apart, ready to perform a pinch or grab gesture, or a pre-tap geometry with one or more fingers extended and the palm facing away from the user), whether the hand is in a predetermined position relative to the user's viewpoint (e.g., below the user's head, above the user's waist, extended at least 15 cm, 20 cm, 25 cm, 30 cm, or 50 cm from the body), and / or whether the hand has moved in a particular manner (e.g., above the user's waist, moved toward an area in front of the user below the user's head, or away from the user's body or legs). In some embodiments, the ready state is used to determine whether an interactive element of a user interface responds to attentional (e.g., gaze) input.

[0161] In scenarios where input is described with reference to air gestures, it should be understood that similar gestures can also be detected using a hardware input device attached to or held by one or more of the user's hands, where the position of the hardware input device in space can be tracked using optical tracking, one or more accelerometers, one or more gyroscopes, one or more magnetometers, and / or one or more inertial measurement units, and where the position and / or movement of the hardware input device is substituted for the position and / or movement of the one or more hands in the corresponding air gesture(s). It should be understood that in scenarios where input is described with reference to air gestures, similar gestures can also be detected using a hardware input device attached to or held by one or more of the user's hands. User input can be detected using controls included in a hardware input device, such as one or more touch-sensitive input elements, one or more pressure-sensitive input elements, one or more buttons, one or more knobs, one or more dials, one or more joysticks, one or more hand or finger covers capable of detecting the position or change in position of parts of the hands and / or fingers relative to each other, relative to the user's body, and / or relative to the user's physical environment, and / or other hardware input device controls, where user input using controls included in a hardware input device is used in place of a hand and / or finger gesture, such as an air tap or air pinch, in a corresponding air gesture(s). For example, a selection input described as being made with an air tap or air pinch input can alternatively be detected with a button press, a tap on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input.As another example, movement input described as being made by an air pinch and drag may alternatively be detected based on interaction with a hardware input control, such as a press and hold of a button, a touch on a touch-sensitive surface, a press on a pressure-sensitive surface, or based on hardware input followed by the movement of another hardware input device in space (e.g., accompanying the hand with which the hardware input device is associated). Similarly, two-handed input, including the movement of both hands relative to one another, may be made using one air gesture and one hardware input device held in the hand not making the air gesture, two hardware input devices held in separate hands, or two air gestures made by separate hands, using various combinations of air gestures and / or input detected by one or more of the hardware input devices described above.

[0162] In some embodiments, the software may be downloaded to the controller 110 in electronic form, for example, over a network, or alternatively may be provided on a tangible, non-transitory medium, such as an optical, magnetic, or electronic memory medium. In some embodiments, the database 408 is similarly stored in memory associated with the controller 110. Alternatively, or additionally, some or all of the described functionality of the computer may be implemented in dedicated hardware, such as a custom or semi-custom integrated circuit or a programmable digital signal processor (DSP). While the controller 110 is shown in FIG. 4 as, by way of example, a separate unit from the image sensor 404, some or all of the processing functionality of the controller may be implemented by a suitable microprocessor and software, or by dedicated circuitry within the housing of the image sensor 404 (e.g., a hand tracking device), or otherwise associated with the image sensor 404. In some embodiments, at least some of these processing functions may be performed by a suitable processor integrated with the display generation component 120 (e.g., in a television set, handheld device, or head-mounted device) or using any other suitable computerized device, such as a game console or media player. The sensing function of the image sensor 404 may likewise be integrated into a computer or other computerized device that is controlled by the sensor output.

[0163] FIG. 4 also includes a schematic diagram of a depth map 410 captured by the image sensor 404, according to some embodiments. The depth map includes a matrix of pixels having respective depth values, as described above. A pixel 412 corresponding to the hand 406 is segmented from the background and wrist in this map. The intensity of each pixel in the depth map 410 is inversely proportional to the depth value, i.e., the measured z-distance from the image sensor 404, with increasing depth resulting in darker shades. The controller 110 processes these depth values ​​to identify and segment components of the image (i.e., groups of adjacent pixels) that have characteristics of a human hand. These characteristics can include, for example, the overall size, shape, and frame-to-frame motion of the depth map sequence.

[0164] 4 also schematically illustrates a hand skeleton 414 that the controller 110 ultimately extracts from the depth map 410 of the hand 406, according to some embodiments. In FIG. 4, the hand skeleton 414 is overlaid on a hand background 416 that was segmented from the original depth map. In some embodiments, key feature points on the hand (e.g., knuckles, fingertips, center of the palm, end of the hand where it connects to the wrist, etc.), and optionally the wrist or arm connected to the hand, are identified and positioned on the hand skeleton 414. In some embodiments, the location and movement of these key feature points over multiple image frames are used by the controller 110 to determine hand gestures performed by the hand or the current state of the hand, according to some embodiments.

[0165] FIG. 5 shows an exemplary embodiment of eye tracking device 130 ( FIG. 1A ). In some embodiments, eye tracking device 130 is controlled by eye tracking unit 243 ( FIG. 2 ) to track the position and movement of a user's gaze relative to scene 105 or relative to XR content displayed via display generation component 120. In some embodiments, eye tracking device 130 is integrated with display generation component 120. For example, in some embodiments, if display generation component 120 is a head-mounted device such as a headset, helmet, goggles, or glasses, or a handheld device disposed in a wearable frame, the head-mounted device includes both components for generating XR content for viewing by the user and components for tracking the user's gaze relative to the XR content. In some embodiments, eye tracking device 130 is separate from display generation component 120. For example, if the display generation component is a handheld device or an XR chamber, eye tracking device 130 is optionally a device separate from the handheld device or the XR chamber. In some embodiments, eye tracking device 130 is a head-mounted device or part of a head-mounted device. In some embodiments, head-mounted eye tracking device 130 is optionally used in conjunction with head-mounted or non-head-mounted display generating components. In some embodiments, eye tracking device 130 is not a head-mounted device, and is optionally used in combination with head-mounted display generating components. In some embodiments, eye tracking device 130 is not a head-mounted device, and is optionally part of non-head-mounted display generating components.

[0166] In some embodiments, the display generation component 120 uses a display mechanism (e.g., left and right near-eye display panels) that displays frames including left and right images in front of the user's eyes to provide the user with a 3D virtual view. For example, the head-mounted display generation component may include left and right optical lenses (referred to herein as eyepieces) positioned between the display and the user's eyes. In some embodiments, the display generation component may include or be coupled to one or more external video cameras that capture video of the user's environment for display. In some embodiments, the head-mounted display generation component may have a transparent or translucent display that allows the user to view the physical environment directly and display virtual objects on the transparent or translucent display. In some embodiments, the display generation component projects virtual objects into the physical environment. The virtual objects are projected, for example, onto a physical surface or as a hologram, allowing an individual using the system to observe the virtual objects superimposed on the physical environment. In such cases, separate display panels and image frames for the left and right eyes may not be required.

[0167] As shown in FIG. 5 , in some embodiments, eye tracking device 130 (e.g., gaze tracking device) includes at least one eye tracking camera (e.g., an infrared (IR) camera or near-IR (NIR) camera) and an illumination source (e.g., an IR or NIR light source such as an array or ring of LEDs) that emits light (e.g., IR or NIR light) toward the user's eyes. The eye tracking camera may be aimed at the user's eyes to receive reflected IR or NIR light from the light source directly from the eyes, or alternatively, may be aimed at a “hot” mirror positioned between the user's eyes and a display panel that reflects the IR or NIR light from the eyes to the eye tracking camera while allowing visible light to pass through. Eye tracking device 130 optionally captures images of the user's eyes (e.g., as a video stream captured at 60-120 frames per second (fps)), analyzes the images to generate eye tracking information, and communicates the eye tracking information to controller 110. In some embodiments, the user's eyes are tracked separately by their respective eye tracking cameras and illumination sources. In some embodiments, only one eye of the user is tracked by a separate eye-tracking camera and lighting source.

[0168] In some embodiments, the eye tracking device 130 is calibrated using a device-specific calibration process to determine the eye tracking device's parameters for the particular operating environment 100, such as the 3D geometric relationships and parameters of the LEDs, camera, hot mirror (if present), eyepiece, and display screen. The device-specific calibration process may be performed at a factory or another facility before delivery of the AR / VR equipment to the end user. The device-specific calibration process may be an automatic or manual calibration process. The user-specific calibration process may include estimation of a particular user's eye parameters, such as pupil location, central visual location, optical axis, visual axis, eye spacing, etc. According to some embodiments, once the device-specific and user-specific parameters for the eye tracking device 130 have been determined, images captured by the eye tracking camera can be processed using a glint-assisted method to determine the user's current visual axis and point of gaze relative to the display.

[0169] As shown in FIG. 5, eye tracking device 130 (e.g., 130A or 130B) includes an eyepiece(s) 520 and a gaze tracking system including at least one eye tracking camera 540 (e.g., an infrared (IR) or near-IR (NIR) camera) positioned on the side of the user's face where eye tracking occurs and an illumination source 530 (e.g., an IR or NIR light source such as an array or ring of NIR light emitting diodes (LEDs)) that emits light (e.g., IR or NIR light) toward the user's eye(s) 592. The eye tracking camera 540 may be positioned between the user's eye(s) 592 and the display 510 (e.g., the left or right display panel of a head-mounted display, or the display of a handheld device, a projector, etc.) and may be directed at a mirror 550 that reflects IR or NIR light from the eye(s) 592 while transmitting visible light (e.g., as shown at the top of FIG. 5), or may be directed at the user's eye(s) 592 to receive reflected IR or NIR light from the eye(s) 592 (e.g., as shown at the bottom of FIG. 5).

[0170] In some embodiments, controller 110 renders AR or VR frames 562 (e.g., left and right frames for left and right display panels) and provides frames 562 to display 510. Controller 110 uses gaze tracking input 542 from eye tracking camera 540 for various purposes, such as in processing frames 562 for display. Controller 110 optionally estimates the user's viewpoint on display 510 based on gaze tracking input 542 obtained from eye tracking camera 540, using a glint-assisted method or other suitable method. The viewpoint estimated from gaze tracking input 542 is optionally used to determine the direction the user is currently looking.

[0171] Some possible use cases of the user's current gaze direction are described below, but are not intended to be limiting. As an exemplary use case, the controller 110 can render virtual content differently based on the determined user's gaze direction. For example, the controller 110 may generate virtual content with higher resolution in a central visual area determined from the user's current gaze direction than in a peripheral area. As another example, the controller may position or move virtual content within a view based at least in part on the user's current gaze direction. As another example, the controller may display particular virtual content within a view based at least in part on the user's current gaze direction. As another exemplary use case in an AR application, the controller 110 can orient an external camera to capture the physical environment of the XR experience and focus in the determined direction. The external camera's autofocus mechanism can then focus on an object or surface within the environment the user is currently viewing on the display 510. As another exemplary use case, eyepiece 520 may be a focusable lens, and eye-tracking information is used by the controller to adjust the focus of eyepiece 520 so that the virtual object the user is currently looking at has the proper binocular coordination to match the convergence of the user's eyes 592. Controller 110 can utilize the eye-tracking information to orient and focus eyepiece 520 so that close objects the user is looking at appear at the correct distance.

[0172] In some embodiments, the eye tracking device is part of a head-mounted device that includes a display (e.g., display 510), two eyepieces (e.g., eyepiece(s) 520), an eye tracking camera (e.g., eye tracking camera(s) 540), and a light source (e.g., illumination source 530 (e.g., IR or NIR LED)) mounted within the wearable housing. The light source emits light (e.g., IR light or NIR light) toward the user's eye(s) 592. In some embodiments, the light sources may be arranged in a ring or circle around each lens, as shown in FIG. 5. In some embodiments, as an example, eight illumination sources 530 (e.g., LEDs) are arranged around each lens 520. However, more or fewer illumination sources 530 may be used, and other arrangements and locations of the illumination sources 530 may be used.

[0173] In some embodiments, the display 510 emits light in the visible light range and not in the IR or NIR range, and therefore does not introduce noise into the gaze tracking system. Note that the location and angle of the eye tracking camera(s) 540 are given by way of example and are not intended to be limiting. In some embodiments, a single eye tracking camera 540 is located on each side of the user's face. In some embodiments, two or more NIR cameras 540 may be used on each side of the user's face. In some embodiments, a camera 540 with a wider field of view (FOV) and a camera 540 with a narrower FOV may be used on each side of the user's face. In some embodiments, a camera 540 operating at one wavelength (e.g., 850 nm) and a camera 540 operating at a different wavelength (e.g., 940 nm) may be used on each side of the user's face.

[0174] Embodiments of an eye tracking system such as that shown in FIG. 5 may be used, for example, in computer-generated reality, virtual reality, and / or mixed reality applications to provide a user with a computer-generated reality, virtual reality, augmented reality, and / or augmented virtual experience.

[0175] FIG. 6 illustrates a glint-assisted gaze tracking pipeline according to some embodiments. In some embodiments, the gaze tracking pipeline is implemented by a glint-assisted gaze tracking system (e.g., eye tracking device 130 as shown in FIGS. 1A and 5). The glint-assisted gaze tracking system can maintain a tracking state. Initially, the tracking state is off or "no." When in the tracking state, the glint-assisted gaze tracking system tracks the pupil contour and glint in the current frame using prior information from previous frames when analyzing the current frame. When not in the tracking state, the glint-assisted gaze tracking system attempts to detect the pupil and glint in the current frame, and if successful, initializes the tracking state to "yes" and continues in the tracking state for the next frame.

[0176] As shown in FIG. 6, an eye-tracking camera can capture left and right images of a user's left and right eyes. The captured images are then input into an eye-tracking pipeline for processing beginning at 610. As indicated by the arrow returning to element 600, the eye-tracking system can continue to capture images of the user's eyes at a rate of, for example, 60-120 frames per second. In some embodiments, each set of captured images may be input into the pipeline for processing. However, in some embodiments, or under some conditions, not all captured frames are processed by the pipeline.

[0177] At 610, if the tracking status is yes for the currently captured image, the method proceeds to element 640. If the tracking status is no at 610, the image is analyzed to detect the user's pupil and glint in the image, as shown at 620. If the pupil and glint are successfully detected at 630, the method proceeds to element 640. If not, the method returns to element 610 to process the next image of the user's eyes.

[0178] At 640, proceeding from element 610, the current frame is analyzed to track pupils and glints based in part on previous information from the previous frame. At 640, proceeding from element 630, a tracking state is initialized based on the detected pupils and glints in the current frame. The results of the processing at element 640 are checked to ensure that the tracking or detection results are reliable. For example, the results can be checked to determine whether a sufficient number of glints are successfully tracked or detected in the current frame to perform pupil and gaze estimation. At 650, if the results are not reliable, the tracking state is set to no at element 660, and the method returns to element 610 to process the next image of the user's eyes. At 650, if the results are reliable, the method proceeds to element 670. At 670, the tracking state is set to yes (if not already yes), and the pupil and glint information is passed to element 680 to estimate the user's gaze point.

[0179] 6 is intended to serve as an example of eye-tracking technology that may be used in particular implementations. As will be recognized by those skilled in the art, other eye-tracking technologies, now existing or developed in the future, may be used in place of or in combination with the glint-assisted eye-tracking technology described herein in computer system 101 to provide a user with an XR experience according to various embodiments.

[0180] In some embodiments, the captured portion of the real-world environment 602 is used to provide the user with an XR experience, e.g., a mixed reality environment in which one or more virtual objects are overlaid on a representation of the real-world environment 602.

[0181] Accordingly, the description herein describes several embodiments of three-dimensional environments (e.g., XR environments) that include representations of real-world objects and representations of virtual objects. For example, the three-dimensional environment optionally includes a representation of a table present in a physical environment that is captured and displayed within the three-dimensional environment (e.g., actively via a camera and display of the computer system, or passively via a transparent or translucent display of the computer system). As described above, the three-dimensional environment is optionally a mixed reality system based on a physical environment, where the three-dimensional environment is captured by one or more sensors of the computer system and displayed via a display generation component. As a mixed reality system, the computer system can optionally selectively display portions and / or objects of the physical environment such that each portion and / or object of the physical environment appears to exist within the three-dimensional environment displayed by the computer system. Similarly, the computer system can optionally display virtual objects in the three-dimensional environment such that each portion and / or object of the physical environment appears to exist within the real world (e.g., the physical environment) by placing the virtual objects at respective locations within the three-dimensional environment that have corresponding locations in the real world. For example, the computer system optionally displays the vase so that it appears as if the real vase were placed on a table in the physical environment, hi some embodiments, distinct locations in the three-dimensional environment have corresponding locations in the physical environment.Thus, when a computer system is described as displaying a virtual object at a location distinct from a physical object (e.g., at or near the location of a user's hand, or on or near a physical table, etc.), the computer system displays the virtual object at a particular location in the three-dimensional environment so that the virtual object appears to be at or near the physical object in the physical world (e.g., the virtual object is displayed at a location in the three-dimensional environment that corresponds to the location in the physical environment where the virtual object would be displayed if the virtual object were a real object at that particular location).

[0182] In some embodiments, real-world objects present in the physical environment (e.g., and / or visible via display generation components) that are displayed in the three-dimensional environment can interact with virtual objects that exist only in the three-dimensional environment. For example, the three-dimensional environment can include a table and a vase placed on the table, where the table is a view (or representation) of the physical table in the physical environment and the vase is a virtual object.

[0183] In a three-dimensional environment (e.g., a real environment, a virtual environment, or an environment containing a mixture of real and virtual objects), objects may be referred to as having depth or simulated depth, or objects may be referred to as being visible, displayed, or located at different depths. In this context, depth refers to a dimension other than height or width. In some embodiments, depth is defined relative to a fixed set of coordinates (e.g., a room or object has a height, depth, and width defined relative to a fixed set of coordinates). In some embodiments, depth is defined relative to a user's location or viewpoint, where the depth dimension varies based on the user's location and / or the location and angle of the user's viewpoint. In some embodiments where depth is defined relative to the location of the user positioned relative to a surface of the environment (e.g., the floor or ground surface of the environment), objects that are farther away from the user along a line extending parallel to the surface are considered to have a greater depth within the environment, and / or the depth of an object is measured along an axis that extends outward from the user's location and is parallel to the surface of the environment (e.g., depth is defined in a cylindrical or substantially cylindrical coordinate system with the user's position at the center of the cylinder extending from the user's head toward the user's feet). Depth is defined relative to the user's viewpoint (e.g., a direction relative to a point in space that determines which parts of the environment are visible through a head-mounted device or other display). In some embodiments, objects that are further away from the user's viewpoint along a line that extends parallel to the direction of the user's viewpoint are considered to have greater depth in the environment, and / or the depth of an object is measured along an axis that extends from the user's viewpoint and extends outward from a line that is parallel to the direction of the user's viewpoint (e.g., depth is defined in a spherical or substantially spherical coordinate system with the origin of the viewpoint at the center of a sphere extending outward from the user's head).In some embodiments, depth is defined relative to a user interface container (e.g., a window or application in which application and / or system content is displayed), where the user interface container has a height and / or width, and depth is a dimension orthogonal to the height and / or width of the user interface container. In some embodiments, in situations where depth is defined relative to a user interface container, the height and / or width of the container are typically orthogonal or substantially orthogonal to a line extending from a user-based location (e.g., a user's viewpoint or location) to the user interface container (e.g., a center of the user interface container or another feature of the user interface container) when the container is placed or initially displayed in a three-dimensional environment (e.g., such that the depth dimension of the container extends outward, away from the user or the user's viewpoint). In some embodiments, in situations where depth is defined relative to a user interface container, the depth of an object relative to the user interface container refers to the object's position along the depth dimension of the user interface container. In some embodiments, different containers can have different depth dimensions (e.g., different depth dimensions extending in different directions and / or away from different starting points from a user or a user's viewpoint). In some embodiments, when depth is defined for a user interface container, the direction of the depth dimension remains constant for the user interface container when the location of the user interface container, the user, and / or the user's viewpoint changes (e.g., or when multiple different viewers are viewing the same container in a three-dimensional environment, such as during a face-to-face collaboration session, and / or when multiple participants are in a real-time communication session with shared virtual content that includes the container). In some embodiments, in the case of curved containers (e.g., including containers with curved surfaces or curved content regions), the depth dimension optionally extends into the surface of the curved container.In some situations, z separation (e.g., the separation of two objects in the depth dimension), z height (e.g., the distance of one object from another object in the depth dimension), z position (e.g., the position of one object in the depth dimension), z depth (e.g., the position of one object in the depth dimension), or simulated z dimension (e.g., depth used as an object's dimension, an environment's dimension, a direction in space, and / or a direction in a simulated space) are used to refer to the concept of depth as described above.

[0184] In some embodiments, a user can optionally use one or more hands to interact with virtual objects in the three-dimensional environment as if the virtual objects were actual objects in the physical environment. For example, as described above, one or more sensors of the computer system optionally capture one or more of the user's hands and display a representation of the user's hands in the three-dimensional environment (e.g., in a manner similar to displaying real-world objects in the three-dimensional environment described above), or in some embodiments, due to the transparency / translucency of the user interface, or the projection of the user interface onto a transparent / translucent surface, or the portion of the display generating components displaying the projection of the user interface to the user's eyes or the field of view of the user's eyes, the user's hands are visible through the display generating components by the ability to see the physical environment through the user interface. Thus, in some embodiments, the user's hands are displayed at discrete locations in the three-dimensional environment and are treated as if they were objects in the three-dimensional environment that can interact with virtual objects in the three-dimensional environment as if they were actual physical objects in the physical environment. In some embodiments, the computer system can update the display of the representation of the user's hands in the three-dimensional environment in conjunction with the movement of the user's hands in the physical environment.

[0185] In some of the embodiments described below, for example, for purposes of determining whether a physical object is directly interacting with a virtual object (e.g., whether a hand is touching, grabbing, holding, etc., a virtual object, or whether it is within a threshold distance from the virtual object), the computer system can optionally determine an “effective” distance between the physical object in the physical world and the virtual object in the three-dimensional environment. For example, a hand directly interacting with a virtual object optionally includes one or more of the fingers of a hand pressing a virtual button, a user's hand grasping a virtual vase, two fingers of a user's hand pinching / holding an application's user interface together, and any other types of interactions described herein. For example, when determining whether and / or how a user is interacting with a virtual object, the computer system optionally determines the distance between the user's hand and the virtual object. In some embodiments, the computer system determines the distance between the user's hand and the virtual object by determining the distance between the location of the hand in the three-dimensional environment and the location of the target virtual object in the three-dimensional environment. For example, one or more hands of a user are positioned at particular positions in the physical world, which the computer system optionally captures and displays at particular corresponding positions in the three-dimensional environment (e.g., positions in the three-dimensional environment at which the hands are displayed, if the hands are virtual rather than physical hands). The positions of the hands in the three-dimensional environment are optionally compared to positions of target virtual objects in the three-dimensional environment to determine a distance between the user's one or more hands and the virtual objects. In some embodiments, the computer system optionally determines the distance between a physical object and a virtual object by comparing positions in the physical world (e.g., as opposed to comparing positions in the three-dimensional environment).For example, when determining the distance between one or more of a user's hands and a virtual object, the computer system optionally determines the corresponding location in the physical world of the virtual object (e.g., the position where the virtual object would be located in the physical world if the virtual object were a physical object rather than a virtual object), and then determines the distance between the corresponding physical position and the user's one or more hands. In some embodiments, the same technique is optionally used to determine the distance between any physical object and any virtual object. Thus, as described herein, when determining whether a physical object is in contact with a virtual object or whether a physical object is within a threshold distance of a virtual object, the computer system optionally performs any of the above-mentioned techniques to map the location of the physical object to the three-dimensional environment and / or to map the location of the virtual object to the physical environment.

[0186] In some embodiments, the same or similar techniques are used to determine where and what a user's gaze is directed at and / or where and what a physical stylus held by the user is directed at. For example, if a user's gaze is directed at a particular position in the physical environment, the computer system optionally determines a corresponding position in the three-dimensional environment (e.g., a virtual position of the gaze), and if a virtual object is located at that corresponding virtual position, the computer system optionally determines that the user's gaze is directed at that virtual object. Similarly, the computer system can optionally determine where the physical stylus is pointing in the physical environment based on the orientation of the physical stylus. In some embodiments, based on this determination, the computer system determines a corresponding virtual position in the three-dimensional environment that corresponds to the location in the physical environment where the stylus is pointing, and optionally determines that the stylus is pointing to the corresponding virtual position in the three-dimensional environment.

[0187] Similarly, embodiments described herein may refer to the location of a user (e.g., a user of a computer system) and / or the location of the computer system within a three-dimensional environment. In some embodiments, a user of a computer system is holding, wearing, or otherwise located at or near the computer system. Thus, in some embodiments, the location of the computer system is used as a proxy for the location of the user. In some embodiments, the location of the computer system and / or the user within the physical environment corresponds to a distinct location within the three-dimensional environment. For example, if a user stands at a location facing a distinct portion of the physical environment that is visible through the display generating components, the location of the computer system is the location within the physical environment (and its corresponding location within the three-dimensional environment) at which the user would see objects within the physical environment in the same position, orientation, and / or size (e.g., absolutely and / or relative to each other) as the objects are visible through the display generating components of the computer system within the three-dimensional environment. Similarly, if the virtual objects displayed in the three-dimensional environment were physical objects in the physical environment (e.g., the physical objects were located in the same physical environment location and had the same physical environment size and orientation as in the three-dimensional environment), the location of the computer system and / or user is the position at which the user would see the virtual objects in the physical environment in the same position, orientation, and / or size (e.g., absolutely and / or relative to each other and to real-world objects) as they were displayed by the display generation components of the computer system in the three-dimensional environment.

[0188] In this disclosure, various input methods are described with respect to interaction with a computer system. Where one example is provided using one input device or input method and another example is provided using a different input device or input method, it should be understood that each example may be compatible with, and optionally utilize, the input device or input method described with respect to the other example. Similarly, various output methods are described with respect to interaction with a computer system. Where one example is provided using one output device or output method and another example is provided using a different output device or output method, it should be understood that each example may be compatible with, and optionally utilize, the output device or output method described with respect to the other example. Similarly, various methods are described with respect to interaction with a virtual environment or a mixed reality environment via a computer system. Where one example is provided using interaction with a virtual environment and another example is provided using a mixed reality environment, it should be understood that each example may be compatible with, and optionally utilize, the method described with respect to the other example. Thus, this disclosure discloses embodiments that are combinations of features of multiple examples, without exhaustively listing all features of the embodiments in the description of each exemplary embodiment. User Interface and Related Processes

[0189] We now turn our attention to embodiments of user interfaces (“UIs”) and associated processes that may be executed in a computer system, such as a portable multifunction device or a head-mounted device, equipped with display generating components, one or more input devices, and (optionally) one or more cameras.

[0190] 7A-7D show an example of a computer system for displaying immersive virtual content, displaying virtual content showing areas with high potential for interaction, according to some embodiments.

[0191] 7A illustrates computer system 101 displaying a three-dimensional environment 702 from the perspective of user 701, shown in an overhead view (e.g., facing the back wall of the physical environment in which computer system 101 is located), via a display generating component (e.g., display generating component 120 of FIG. 1 ). As described above with reference to FIGS. 1-6 , computer system 101 optionally includes a display generating component (e.g., a touchscreen) and multiple image sensors (e.g., image sensor 314 of FIG. 3 ). The image sensors optionally include one or more of a visible light camera, an infrared camera, a depth sensor, or any other sensor that computer system 101 could use to capture one or more images of a user or a portion of a user (e.g., one or more of the user's hands) while the user interacts with computer system 101. In some embodiments, the user interfaces shown and described below may also be realized on a head-mounted display that includes display generating components that display the user interface or three-dimensional environment to the user, and sensors (e.g., external sensors facing outward from the user) for detecting movements of the physical environment and / or the user's hands, such as movements that are interpreted by the computer system as gestures, such as air gestures, and / or the user's line of sight (e.g., internal sensors facing inward toward the user's face).

[0192] 7A , computer system 101 captures one or more images of the physical environment surrounding computer system 101 (e.g., operating environment 100), including one or more objects within the physical environment surrounding computer system 101. In some embodiments, computer system 101 displays a representation of the physical environment in three-dimensional environment 702, or portions of the physical environment are visible via display generation component 120 of computer system 101. For example, three-dimensional environment 702 includes portions of the left and right walls, ceiling, and floor in the physical environment of user 701, and also includes physical object 706, which is a physical block, and physical object 710, which is a table.

[0193] 7A, three-dimensional environment 702 includes virtual content, such as virtual content 708A, virtual content 708B, and virtual content 704. Such virtual content is, optionally, any element displayed by computer system 101 that is not included in the physical environment of computer system 101.

[0194] In some embodiments, virtual content 704 is displayed overlaid on a portion (e.g., an outline) of the physical environment. In some embodiments, virtual content 704 corresponds to an area of ​​three-dimensional environment 702 where computer system 101 anticipates possible user interaction when displaying the virtual environment associated with virtual content 708A or other virtual content, as described below. For example, virtual content 704 and / or a portion of the physical environment optionally correspond to a user's "viewing area." For example, computer system 101 optionally anticipates that, when displaying the virtual environment associated with virtual content 708A or other virtual content, the user will likely be standing (e.g., standing) within an area of ​​the physical environment corresponding to where virtual content 704 is located. In some embodiments, virtual content 708 optionally corresponds to a representation corresponding to a virtual environment (e.g., an immersive visual experience and / or an application providing an immersive visual experience). In some embodiments, computer system 101 begins displaying the virtual content at an immersion level above an immersion threshold in response to detecting an input including a request to display such virtual content, as further described with reference to FIG. 7B . Immersion levels are described in more detail with reference to method 800. Thus, virtual content 704 is, optionally, a visual indication to user 701 of distinct portions of the physical environment that the user is likely to recognize while computer system 101 is displaying the virtual environment associated with virtual content 708A or other virtual content. For example, if a physical object, such as physical object 706, is present that warrants the user's attention, virtual content 704 directs the user's focus toward physical object 706. For example, as shown in FIG. 7C , the user may be in danger of colliding with physical object 706 while computer system 101 is displaying virtual content associated with virtual content 708A. Thus, in some embodiments, virtual content 704 enhances the user's awareness of relationships between the user's physical spaces prior to interacting with such virtual content.

[0195] In some embodiments, virtual content 704 is displayed without displaying virtual content 708A and / or virtual content 708B. In some embodiments, virtual content 708A and / or 708B are displayed without displaying virtual content 704. In some embodiments, the visual appearance of virtual content 704, 708A, and 708B differs from that shown in FIG. 7A . For example, the individual virtual contents are optionally displayed with different borders, lighting effects, colors, saturations, hues, intensities, animations, shapes, and / or positions than those shown. In some embodiments, virtual content 708B corresponds to a simulated shadow cast by virtual content 708A in response to one or more simulated light sources positioned above virtual content 708A but that are optionally not visible. For example, a first simulated light source positioned perpendicular to the floor of the physical environment and above virtual content 708A casts a virtual shadow (e.g., virtual content 708B) that is optionally centered below virtual content 708A (e.g., on virtual content 704). In some embodiments, the simulated light sources are displayed and / or positioned at different positions and / or angles relative to the virtual content 708A, such that additional virtual shadows of various shapes, positions, and / or intensities are displayed in addition to or instead of the virtual content 708B (e.g., on the virtual content 704). Additionally or alternatively, one or more simulated light sources may additionally cause the virtual content 708A to appear with a specular lighting effect, simulating the visual effect of real-world light shining on an at least semi-reflective surface, such that bright areas or spots appear on the virtual content 708A to suggest the position of the light source aimed at the virtual content 708A.

[0196] FIG. 7A1 shows a perspective view of user 701's physical environment corresponding to user 701's position in FIG. 7A. For example, user 701 is positioned in his or her physical environment outside of the area of ​​his or her physical environment corresponding to content 704 (e.g., the area shown by the dashed line in FIG. 7A1). FIG. 7B shows modifications to environment 702 in response to input from user 701. As shown in FIG. 7B, the input includes movement of user 701, as shown in the overhead view of environment 702, to a location within environment 702 within the area corresponding to virtual content 704. Movement of user 701 from outside the area corresponding to virtual content 704 to inside the area corresponding to virtual content 704 is also shown in FIGS. 7A1 through 7B2, where user 701 is shown as moving within the area of ​​the physical environment corresponding to content 704 (e.g., the area shown by the dashed line in FIG. 7B2). In some embodiments, feedback and / or prompts are displayed in response to such input. For example, virtual content 712 (e.g., a confirmation prompt) is optionally displayed to ensure that the user wishes to display the virtual content at an immersion level greater than the immersion threshold level. In response to an input corresponding to a request to display the virtual content at an immersion level greater than the immersion threshold, computer system 101 optionally displays virtual content 712 associated with displaying the virtual content at an immersion level greater than the immersion threshold. For example, virtual content 712 optionally includes respective information associated with the virtual content to be displayed at an immersion level greater than the immersion threshold. The respective information optionally notifies the user of computer system 101 that the virtual content will be displayed (e.g., "virtual environment is loaded"). In some embodiments, the respective information includes a name associated with the virtual content (e.g., the name of the application providing the virtual content to be displayed at the immersion level and / or the name of the immersive visual experience, such as a beach, forest, and / or campsite). The respective information optionally also includes a prompt to confirm that the user is aware of their physical environment.For example, each piece of information optionally includes a selectable option 712-1, which is selectable to confirm user intent to display virtual content at the immersive level (e.g., using mouse and cursor clicks, attention and air gestures, physical and / or virtual button actuations, and / or another suitable selection input directed at the selectable option). In some embodiments, each piece of information optionally includes a selectable option 712-2, which provides confirmation of user intent as described above and is further selectable to forgo display of at least a portion of the respective piece of information 712 in response to a later received request to display virtual content at the immersive level. For example, after receiving a selection of selectable option 712-2, computer system 101 is optionally made aware that the user does not want to see virtual content 712 and / or selectable options 712-1 and 712-2 in the future. Thus, computer system 101 subsequently detects an input corresponding to a request to load virtual content at the immersive level, partially or fully forgoes display of such virtual content as described above, and optionally proceeds to display the virtual content at the immersive level. Thus, the virtual content 712 helps the computer system 101 and the user 701 confirm the intent to display the virtual content, and optionally reduces the need to continue displaying the virtual content 712.

[0197] As described with reference to method 800, in some embodiments, as part of the input, computer system 101 detects that the locations of distinct portions of user 701 correspond to distinct portions of the physical environment (e.g., corresponding to areas of virtual content 704), referred to herein as visibility regions. In some embodiments, computer system 101 is optionally agnostic as to which particular portions of the user correspond to visibility regions. For example, a first input including the movement of the user's feet into the region and a second input including the movement of the user's hands into the region are optionally treated similarly or identically, and virtual content 712 is optionally displayed in response to the first and / or second input. In some embodiments, computer system 101 detects the inputs according to the expected movement of one or more portions of the user moving into the region. For example, computer system 101 optionally displays virtual content 712 in response to detecting that both of the user's feet have entered the region, but not in response to one foot entering the region and / or not in response to the user's hand entering the region. Thus, as shown in FIG. 7B, computer system 101 displays virtual content 712 in response to the user's feet entering a distinct area of ​​the physical environment corresponding to virtual content 704.

[0198] In some embodiments, additional virtual content associated with virtual content 704 is displayed in response to the input. For example, computer system 101 optionally displays one or more selectable options, such as grabber 714-1, grabber 714-2, and / or grabber 714-3. In some embodiments, computer system 101 detects input directed at grabber 714-1, grabber 714-2, and / or grabber 714-3 associated with virtual content 704 and modifies one or more dimensions of virtual content 704. For example, computer system 101 optionally detects a user's attention (e.g., gaze) directed at a respective selectable option 714 simultaneously with detecting an air gesture of hand 703A. For example, the air gesture is optionally an air pinch gesture including contact between the index finger and thumb of hand 703A. In some embodiments, the input includes movement of hand 703A while the air pinch gesture is maintained. For example, while the air pinch gesture is maintained, computer system 101 detects hand movement and modifies one or more dimensions of virtual content 704 according to the movement. For example, as indicated by note 715B, computer system 101 detects movement of hand 703A while the air pinch gesture is maintained and scales (e.g., stretches) virtual content 704 based on movement of hand 703A away from user 701 and / or scales (e.g., shrinks) virtual content 704 based on movement of hand 703A toward user 701 moving parallel to a first dimension (e.g., depth) of virtual content 704.

[0199] In some embodiments, computer system 101 scales virtual content 704 by the amount of scaling in a first direction based on the magnitude of the component of hand 703A's movement parallel to the first direction, while ignoring hand movement in a second direction different from the first direction. For example, as described with reference to grabber 714-1, computer system 101 optionally detects movement of hand 703A to the left and away from the user while maintaining an air pinch gesture and while the user's attention is directed at grabber 714-1, and forgoes consideration of the magnitude of the leftward movement and instead scales virtual content 704 based only on the magnitude of the component of movement toward or away from user 701 (e.g., parallel to the depth of virtual content 704). Similarly, with reference to grabber 714-3, computer system 101 optionally scales virtual content 704 according to the magnitude of hand 703A's leftward and / or rightward movement and forgoes consideration of the magnitude of the movement toward and / or away from user 701. In some embodiments, computer system 101 scales virtual content 704 along multiple dimensions according to movement in multiple directions. For example, with reference to grabber 714-2, computer system 101 optionally scales virtual content 704 according to the magnitude of hand 703A movement toward user 701, away from user 701, to the user's left, and / or to the user's right to scale the width and / or length of virtual content 704. In some embodiments, the magnitude of the user's movement scales virtual content 704 equally in multiple directions. For example, moving hand 703A forward in a first direction by a movement of a first magnitude optionally scales virtual content 704 equally by a first amount along first and second dimensions (e.g., its depth and width). Similarly, moving hand 703A to the right by a first movement magnitude optionally scales virtual content 704 by a first amount along the first and second dimensions.

[0200] In some embodiments, computer system 101 optionally forgoes displaying virtual content 712 pursuant to satisfying one or more criteria, further described with reference to method 800. For example, computer system 101 optionally recognizes that user 701 recently received input requesting display of virtual content at an immersion level higher than an immersion threshold, and therefore forgoes displaying virtual content 712. Such a scenario is optionally beneficial when, upon the user temporarily or accidentally navigating outside the boundaries of virtual content 704 and thereby re-entering the boundaries, computer system 101 optionally forgoes redundantly prompting the user to confirm their intention to display the virtual content at the immersion level. In some embodiments, virtual content 712 is displayed with distinct opacity and / or other visual characteristics (e.g., brightness, color, border, and / or visual effects) to prevent the user from accidentally overlooking virtual content 712. For example, virtual content 712 is optionally fully opaque and optionally displayed with a colored border.

[0201] In some embodiments, in response to selection of selectable options 712-1 and / or 712-2, computer system 101 initiates a process to evaluate the user's physical environment. The evaluation optionally includes a scan of the physical environment. In some embodiments, the evaluation begins before selection of selectable options 712-1 and / or 712-2, such as in response to an input to display virtual content at an immersion level higher than an immersion threshold, in response to device power-on, and / or in response to other user interaction with computer system 101. In some embodiments, computer system 101 displays a representation of the scan, such as a grid pattern superimposed on the subject of the scan. In some embodiments, the scan includes a viewable area and / or area bounded by virtual content 704 of the user's physical environment. In some embodiments, the computer system does not begin displaying the virtual content at an immersive level until such a scan is complete. In some embodiments, the scan includes most or all of the user's physical environment in front of the user's viewpoint and a portion of the environment behind the user's viewpoint. In some embodiments, the scan includes one or more portions of the physical environment corresponding to a viewing area corresponding to virtual content 704 (e.g., discrete areas of the physical environment with which the user is likely to interact) and / or one or more portions of the physical environment outside the viewing area. In some embodiments, computer system 101 optionally detects a selection of selectable options 712-1 and / or 712-2 and, in response to such selection, begins displaying the virtual content at an immersion level above an immersion threshold and / or stops displaying virtual content 712, as described in further detail below.

[0202] FIG. 7B1 illustrates concepts similar and / or identical to those illustrated in FIG. 7B (which have many of the same reference numbers). Unless otherwise indicated below, elements illustrated in FIG. 7B1 that have the same reference numbers as elements illustrated in FIGS. 7A-7D are understood to have one or more or all of the same characteristics. FIG. 7B1 includes a computer system 101 that includes (or is the same as) a display generation component 120. In some embodiments, the computer system 101 and the display generation component 120 have one or more of the characteristics of the computer system 101 illustrated in FIGS. 7A-7D and the display generation component 120 illustrated in FIGS. 1 and 3, respectively, and in some embodiments, the computer system 101 and the display generation component 120 illustrated in FIGS. 7A-7D have one or more of the characteristics of the computer system 101 and the display generation component 120 illustrated in FIG. 7B1.

[0203] In FIG. 7B1 , display generating component 120 includes one or more internal image sensors 314a (e.g., eye-tracking cameras 540 described below with reference to FIG. 5 ) oriented toward the user's face. In some embodiments, internal image sensor 314a is used for eye tracking (e.g., detecting the user's gaze). Internal image sensor 314a is optionally located on left and right portions of display generating component 120 to enable eye tracking of the user's left and right eyes. Display generating component 120 also includes external image sensors 314b and 314c facing outward from the user to detect and / or capture the physical environment and / or the user's hand movements. In some embodiments, image sensors 314a, 314b, and 314c have one or more of the characteristics of image sensor 314 described with reference to FIGS. 7A-7D .

[0204] 7B1, display generation component 120 is shown as displaying content that optionally corresponds to the content described as being displayed and / or visible via display generation component 120 with reference to FIGS. 7A-7D. In some embodiments, the content is displayed by a single display (e.g., display 510 of FIG. 5) included in display generation component 120. In some embodiments, display generation component 120 includes two or more displays (e.g., left and right display panels for the user's left and right eyes, respectively, as described with reference to FIG. 5) having display outputs that are merged (e.g., by the user's brain) to create the view of the content shown in FIG. 7B1.

[0205] 7B1 (e.g., the field of view captured by external image sensors 314b and 314c and / or visible to the user via display generating component 120, shown by the dashed line in the overhead view). Because display generating component 120 is optionally a head-mounted device, the field of view of display generating component 120 is optionally the same as or similar to the user's field of view.

[0206] In Figure 7B1, a user is shown performing an air pinch gesture (e.g., with hand 703A) to provide input to computer system 101 to provide user input directed to content displayed by computer system 101. Such depiction is intended to be illustrative and not limiting. The user optionally provides user input using different air gestures and / or using other forms of input, as described with reference to Figures 7A-7D.

[0207] In some embodiments, computer system 101 responds to user input as described with reference to Figures 7A-7D.

[0208] 7B1 , the user's hands are visible in the three-dimensional environment because they are within the field of view of display generation component 120. That is, the user can optionally view, in the three-dimensional environment, any part of their body that is within the field of view of display generation component 120. It will be understood that one or more or all aspects of the present disclosure shown in or described with reference to FIGS. 7A-7D and / or described with reference to the corresponding method(s) are optionally implemented on computer system 101 and display generation unit 120 in a manner the same or similar to that shown in FIG.

[0209] Figure 7C illustrates the display of virtual content at an immersion level greater than the threshold level of immersion in response to input selection option 712-1 of Figure 7B. The virtual content 704 has been scaled in accordance with the care, selection, and desire for scaling the virtual content 704, as described in Figure 7B. Thus, the illustrated virtual content 704 is relatively larger than that shown in Figure 7B.

[0210] As described herein, displaying virtual content at an immersive level optionally includes any suitable method of displaying virtual content that was not displayed before the input requesting the display was received (e.g., to replace at least a portion of the visibility of the physical environment within three-dimensional environment 702) and / or optionally includes modifying a visual characteristic(s) of the virtual content, as described in further detail with reference to method 800. For example, virtual content 716 optionally corresponds to an immersive visual experience. Such an immersive visual experience optionally includes a displayed representation of a simulated real-world scene, such as a previously recorded video of a campsite. In some embodiments, the immersive visual experience optionally includes a depiction of a completely or almost completely virtual environment (e.g., a simulated physical space). For example, virtual content 716 as shown in FIG. 7C shows a virtual sky that is part of the virtual environment at a virtual beach. The virtual content 716 optionally includes additional virtual content, such as user interfaces of applications associated with computer system 101, virtual avatars of users of other computer systems, virtual avatars that do not correspond to users (e.g., non-user characters), virtual objects, and other suitable virtual content. In some embodiments, the display of the virtual content occurs gradually. For example, computer system 101 optionally begins displaying the virtual content 716 starting from a discrete portion of the user's field of view (e.g., right, left, top, center, bottom, a portion corresponding to a previous location of other virtual content, such as virtual content 708A of FIG. 7A , and / or a combination of one or more of such portions). For example, computer system 101 optionally begins displaying the virtual content 716 in an upper region of the user's field of view and, optionally, continues displaying portions of the virtual content 716 toward another discrete portion of the user's field of view (e.g., a lower region) so that the amount of virtual content 716 shown in FIG. 7C is gradually revealed in three-dimensional environment 702. Alternatively, the virtual content 716 is optionally displayed starting from the right side of the user's field of view and ending towards the left side of the user's field of view, or vice versa.Thus, in some embodiments, displaying virtual content at a higher immersion level than the immersion level optionally includes displaying virtual content that was not displayed when the input requesting the display of the virtual content was received.

[0211] As mentioned above, in some embodiments, displaying the virtual content at an immersion level above the immersion threshold optionally includes modifying visual characteristics of the virtual content. For example, computer system 101 optionally applies one or more visual effects, such as blurring, feathering, and / or color space modification (e.g., slightly lower brightness and / or saturation than the final brightness and / or saturation of the individual content) of one or more individual portions of virtual content 716. The one or more respective portions optionally include the most recently displayed portions of virtual content 716. For example, while virtual content 716 is loading from an upper region of the user's field of view toward a lower region of the user's field of view, the bottom-most individual portions of the virtual content are optionally blurred and / or feathered, thus enhancing visual focus and reducing the abrupt loading of such content. In some embodiments, after an additional respective portion of virtual content 716 is displayed at an immersion level above the immersion threshold, computer system 101 modifies the display of the previously displayed respective portions of the virtual content. For example, a first discrete portion that was previously “below” the displayed virtual content 716 is no longer at the bottom as the display of a second discrete portion of the virtual content below the first discrete portion progresses, and thus computer system 101 modifies the first discrete portion to cease displaying the visual effect. For example, the first discrete portion is optionally displayed with a color saturation, a level of translucency, and / or other visual effect. In some embodiments, computer system 101 optionally displays the first portions of the virtual content 716 simultaneously or nearly simultaneously, rather than gradually displaying the first portions of the virtual content 716 along one or more directions (e.g., from left to right, from top to bottom, or some combination thereof). For example, computer system 101 optionally gradually fades in (e.g., increases opacity) the entire first portion of the virtual content 716. In some embodiments, the fading includes a blooming visual effect.The blooming visual effect optionally includes increasing the opacity of a central portion of the first portion of the virtual content 716 at a rate greater than the increase in opacity of distal portions of the first portion.

[0212] In some embodiments, computer system 101 continues to at least temporarily display a portion of a discrete region of the user's physical environment while displaying the virtual content at an immersion level greater than the immersion threshold. For example, computer system 101 optionally displays a first portion of virtual content 716 such that the first portion consumes a majority of the user's field of view, but does not display a second portion of the virtual content at an immersion level greater than the immersion threshold for a period of time (e.g., 0.01, 0.05, 0.1, 0.5, 1, 5, 10, 15, 25, 50, 100, or 500 seconds) and / or until the user provides explicit input (e.g., actuation of a physical or virtual button, input including a voice command, and / or an air gesture such as a user's hand swiping downward toward the bottom of the user's field of view) to initiate display of the second portion at an immersion level greater than the immersion threshold. In some embodiments, the second portion includes a discrete region corresponding to virtual content 704. Although the second portion of the virtual content is not displayed at an immersion level above the immersion threshold, the user optionally has visibility of physical objects in the user's physical environment, such as physical object 706, potential contours such as floor ridges and / or sidewalk curbs, and / or other elements of the user's environment. Such visual configurations allow the user to study the details of their physical environment, clear areas of possible interaction of obstacles, and / or navigate to distinct portions of the area so that their movement and interaction with the physical environment (e.g., around the user's floor) is unimpeded, or at least made known to the user. Thus, in some embodiments, the computer system optionally saves a representation of the user's physical environment that anticipates the user's possible interactions, thereby improving the user's awareness of their surroundings and reducing the likelihood that the user will encounter spatial conflicts and / or collisions while moving and interacting with the virtual content.

[0213] In some embodiments, in response to displaying virtual content 716 at an immersion level greater than the immersion threshold, computer system 101 modifies and / or ceases displaying virtual content 704. For example, before displaying the virtual content at an immersion level greater than the immersion threshold, computer system 101 optionally displays virtual content 704 as an at least partially transparent ring or rectangle superimposed on the floor surrounding the user. When beginning to display the virtual content at an immersion level greater than the immersion threshold, computer system 101 optionally ceases displaying the transparent ring and / or rectangle and replaces the virtual content with second virtual content. In some embodiments, computer system 101 optionally does not cease displaying virtual content 704, but instead modifies the display of virtual content 704. The modified version of virtual content 704 optionally has one or more characteristics of the display of the second virtual content, although it will be understood that the two embodiments, while similar, are optionally different. In some embodiments, the second virtual content is displayed with animation. For example, the second virtual content optionally includes one or more simulated light sources that illuminate a representation of the user's floor. In some embodiments, the one or more simulated light sources include one or more concentric rings of such light emanating from the user's current position (e.g., from the user's feet). For example, the simulated light optionally begins at a point corresponding to a discrete part of the user, such as the user's feet, and spreads outward over time toward outer portions of the viewing area corresponding to the virtual content 704. In some embodiments, the rings additionally or alternatively include a representation of a line emanating from the user and spreading to the floor. In some embodiments, the second virtual content optionally includes pulsing of simulated light throughout the viewing area corresponding to the virtual content 704. For example, the pulsing optionally includes rhythmic brightening and dimming of the viewing area. In some embodiments, the second virtual content corresponds to a larger or smaller area of ​​the representation of the user's physical environment compared to the virtual content 704 shown in FIG. 7B .

[0214] In some embodiments, the display of the second virtual content and / or modification of the virtual content 704 (e.g., effects applied to the virtual content and areas corresponding to the viewable area) occurs simultaneously while the second (e.g., lower) portion of the virtual content 716 is not displayed at an immersion level above the immersion threshold and the first portion of the virtual content 716 is displayed at an immersion level above the threshold. For example, the computer system optionally displays a simulated light spreading across the floor of the user's environment while the lower portion of the virtual content 716 is not displayed. In some embodiments, if the second virtual content is displayed with animation, the computer system 101 stops displaying the animation after a threshold period (e.g., 0.01, 0.05, 0.1, 0.5, 1, 5, 10, 15, 25, 50, 100, or 500 seconds). In some embodiments, after the threshold period, the computer system 101 displays a static visual indication, such as a ring, indicating the boundary of the user's viewable area.

[0215] 7D illustrates replacing a representation of the user's physical environment corresponding to the viewing area with virtual content. For example, after a first portion of virtual content 716 is displayed for a period of time (e.g., 0.01, 0.05, 0.1, 0.5, 1, 5, 10, 15, 25, 50, 100, or 500 seconds) and a second portion of virtual content 716 is not displayed for that period of time, computer system 101 begins displaying the second portion of virtual content 716. In some embodiments, the display of the second portion of virtual content 716 has one or more characteristics of the display of virtual content described with reference to the start of the display of the virtual content of FIG. 7C (e.g., the start of the display of the first portion of virtual content 716). For example, if computer system 101 begins displaying virtual content 716 from an upper region of the user's viewpoint, after allowing the user to view the viewable area for a period of time, the computer system continues to display a second portion of virtual content 716 at an immersion level above the immersion threshold, starting from an upper region of the second portion and progressing downward toward the floor of the environment until the second portion is fully displayed. Thus, upon giving the user an opportunity to observe the viewable area and potentially clear the viewing area of ​​objects, computer system 101 optionally continues to display a fully immersive visual experience. For example, the second portion of virtual content 716 optionally includes the floor of the virtual environment, such as beach sand or ocean water. In some embodiments, replacing the user's representation of the environment with virtual content includes obscuring physical objects in the environment. For example, in FIG. 7D , physical object 706 is no longer visible because virtual content 716 is displayed at an immersion level above the immersion threshold level. Thus, the physical object 706 still occupies physical space in the user's environment, but no longer obstructs the view of the virtual content 716. In some embodiments, the computer system 101 also optionally stops displaying the virtual content 704 while replacing the viewing area with the second portion of the virtual content 716.In some embodiments, the display of the first portion of the virtual content and / or the replacement of the second portion of the virtual content includes fading in (e.g., gradually increasing opacity) the first and / or second portions, and in the case of fading in the second portion, also includes simultaneously fading out (e.g., gradually decreasing opacity) virtual content 704 shown in FIG. 7C . For example, computer system 101 optionally increases the opacity of the second portion of virtual content 716 at a first rate and / or decreases the opacity of virtual content 704 at a second rate (optionally the same as or different from the first rate). In some embodiments, when virtual content not included in virtual content 716 is displayed in the user's viewing area, the computer system also optionally replaces the display of the virtual content not included in virtual content 716 with a separate piece of virtual content within virtual content 716. For example, a virtual window corresponding to an application user interface is optionally displayed in the user's viewing area before computer system 101 begins displaying the second portion of virtual content 716. However, in response to starting to display the second portion of the virtual content 716, the computer system 101 optionally stops and / or fades out the display of the virtual window in addition to replacing the representation of the user's environment (e.g., viewing area).

[0216] 8A-8F are flowcharts illustrating an exemplary method for displaying virtual content having a level of visual saliency greater than a threshold level of visual saliency, according to some embodiments. In some embodiments, method 800 is performed on a computer system (e.g., computer system 101 of FIG. 1 , such as a tablet, smartphone, wearable computer, or head-mounted device) that includes display generation components (e.g., display generation components 120 of FIGS. 1, 3, and 4 ) (e.g., a head-up display, a display, a touchscreen, a projector, etc.) and one or more cameras (e.g., a camera pointing down the user's hand (e.g., a color sensor, an infrared sensor, and other depth-sensing camera) or a camera pointing forward from the user's head). In some embodiments, method 800 is performed by instructions stored on a non-transitory computer-readable storage medium and executed by one or more processors of the computer system, such as one or more processors 202 of computer system 101 (e.g., control unit 110 of FIG. 1A ). Some operations of method 800 are optionally combined and / or the order of some operations is optionally changed.

[0217] In some embodiments, method 800 is performed on a computer system, such as computer system 101 as shown in FIG. 7A , in communication with one or more input devices and a display generation component, such as display generation component 120 as shown in FIG. 7A . For example, a mobile device (e.g., a tablet, smartphone, media player, or wearable device), or a computer or other electronic device. In some embodiments, the display generation component is an external display, such as a display (optionally a touchscreen display) integral with the electronic device, a monitor, projector, television, or hardware component (optionally integrated or external) for projecting a user interface or making the user interface visible to one or more users. In some embodiments, the one or more input devices include electronic devices or components capable of accepting user input (e.g., capturing and / or detecting user input) and transmitting information associated with the user input to the computer system. Examples of input devices include a touchscreen, a mouse (e.g., external), a trackpad (optionally integrated or external), a touchpad (optionally integrated or external), a remote control device (e.g., external), another mobile device (e.g., separate from the computer system), a handheld device (e.g., external), a controller (e.g., external), a camera, a depth sensor, an eye tracking device, and / or a motion sensor (e.g., hand tracking device, hand motion sensor). In some embodiments, the computer system communicates with a hand tracking device (e.g., one or more cameras, depth sensors, proximity sensors, touch sensors (touchscreen, trackpad)). In some embodiments, the hand tracking device is a wearable device such as a smart glove. In some embodiments, the hand tracking device is a handheld input device such as a remote control or a stylus.

[0218] 7B and 7B1 to that shown in FIG. 7C to display virtual content 716 as shown in FIG. 7C , which visually replaces a portion of a representation of a physical environment where a user of the computer system is located while using the computer system, such as a location corresponding to user 701. For example, while optionally displaying a virtual reality (VR) or mixed reality (XR) environment (e.g., in some embodiments, the first three-dimensional environment is an augmented reality (XR) environment such as a virtual reality (VR) environment, a mixed reality (MR) environment, or an augmented reality (AR) environment) including a visual representation (e.g., icons and / or shapes displayed on a physical floor) of an immersive visual experience (e.g., a virtual environment) as described with reference to method 1000, the computer system optionally detects movement of the user of the computer system and / or the user's viewpoint to a position in the physical environment corresponding to (e.g., into) the visual representation. In some embodiments, the request to display virtual content includes actuation of a physical and / or virtual button. In some embodiments, the request to display virtual content includes detecting a user's attention and / or a gesture and / or posture of an individual part of the user (e.g., the user's hand and / or fingers). In some embodiments, the first input includes a request to view an immersive virtual experience (e.g., a virtual environment), such as a mixed reality environment composed primarily of virtual content. In some embodiments, the virtual content and / or virtual environment is a simulated three-dimensional environment displayed in a three-dimensional environment, optionally instead of (e.g., full immersion) or optionally simultaneously with (e.g., partial immersion) a representation of the physical environment. Some examples of virtual environments include a lake environment, a mountain environment, a sunset scene, a sunrise scene, a night environment, a grassy environment, and / or a concert scene, etc. In some embodiments, the virtual environment is based on an actual physical location, such as a museum and / or an aquarium. In some embodiments, the virtual environment is an artist-designed location.Thus, displaying a virtual environment within a three-dimensional environment optionally provides a user with a virtual experience as if the user were physically located within the virtual environment. In some embodiments, the first input is or includes a tap in space or hand air gesture, such as air pointing or air pinching at an icon or other selectable option within the augmented reality (AR) or virtual reality (VR) environment to launch and / or display the virtual environment, or an input using an interface controller within the AR or VR environment to provide input to select an icon or other selectable option to launch and / or display a virtual environment, such as the first virtual environment described below. In some embodiments, the first input includes a user's hand of a computer system performing a pinch air gesture in which the index finger and thumb of the user's hand touch together while the user's attention is directed at an icon or selectable option. In some embodiments, the first input is an attention-only and / or gaze-only input (e.g., does not include input from one or more parts of the user other than the part providing the attention input).

[0219] In some embodiments, in response to detecting a first input via one or more input devices, and in accordance with determining that the first input corresponds to a request to display virtual content at an immersion level greater than an immersion threshold (802b) (e.g., 10, 30, 50, or 75% immersion), the computer system, via its display generation components, displays (802c) a visual indication, such as virtual content 704 shown in FIG. 7C , corresponding to a distinct area of ​​the physical environment with which a user of the computer system is likely to interact while displaying the virtual content at an immersion level greater than the immersion threshold, wherein a representation of the distinct area of ​​the physical environment is visible via the display generation components, such as a portion of environment 702 shown in FIG. 7C . For example, the computer system optionally detects a request to display virtual content, such as XR and / or VR extensions of the user's current environment. In some embodiments, the computer system is currently not displaying virtual content or is displaying a first amount of virtual content (e.g., system user interface elements such as the date, time, and computer system status(ies)) and determines that the first input corresponds to a request to begin displaying second virtual content. In some embodiments, the first input includes a request to view the immersive XR or VR environment such that an amount of virtual content visible and / or presented to a user of the computer system increases in response to the first input. In some embodiments, the computer system determines that the first input includes a request to display virtual content such that the requested virtual content consumes more than a threshold amount of the user's field of view (e.g., 0.1, 1, 3, 5, 10, 15, 30, 45, 90, or 120 degrees) while the user's orientation with respect to the three-dimensional environment is changing. In some embodiments, the computer system displays the virtual content at an opacity level that exceeds an opacity threshold (e.g., 0.01, 0.1, 1, 3, 5, 10, 50, or 90% opacity).In some embodiments, the immersion level includes the relative degree to which the virtual content (e.g., the virtual environment and / or virtual content) displayed by the computer system obscures background content (e.g., content other than the virtual environment and / or virtual content) around / behind the virtual content, and optionally includes the number of items of background content displayed and / or the visual characteristics (e.g., color, contrast, and / or opacity) at which the background content is displayed, the angular range of the virtual content displayed via the display generating components (e.g., 60-degree content displayed at low immersion, 120-degree content displayed at medium immersion, or 180-degree content displayed at high immersion), and / or the percentage of the field of view displayed via the display generating components that is consumed by the virtual content (e.g., 33% of the field of view consumed by the virtual content at low immersion, 66% of the field of view consumed by the virtual content at medium immersion, or 100% of the field of view consumed by the virtual content at high immersion). In some embodiments, the background content is included in the background against which the virtual content is displayed. In some embodiments, background content includes user interfaces (e.g., user interfaces generated by a computer system corresponding to an application), virtual objects (e.g., files or representations of other users generated by a computer system) that are not associated with or included in the virtual environment and / or virtual content, and / or real objects (e.g., pass-through objects that represent real objects in the physical environment around the user that are visible as displayed through the display generating components and / or that are visible through transparent or translucent components of the display generating components because the computer system does not obscure / prevent their visibility through the display generating components). In some embodiments, at a low immersion level (e.g., a first immersion level), the background, virtual, and / or real objects are displayed in an unobscured manner. For example, a virtual environment at a low immersion level is optionally displayed simultaneously with background content, and the background content is optionally displayed at full brightness, color, and / or translucency.In some embodiments, at a higher immersion level (e.g., a second immersion level higher than the first immersion level), background, virtual, and / or real objects are displayed in an obscured manner (e.g., dimmed, blurred, or removed from the display). For example, optionally, a separate virtual environment having a high immersion level is displayed without simultaneously displaying background content (e.g., in full screen or fully immersive mode). As another example, a virtual environment displayed at an intermediate immersion level is optionally displayed simultaneously with dimmed, blurred, or otherwise de-highlighted background content. In some embodiments, the visual characteristics of the background objects differ among the background objects. For example, at a particular immersion level, one or more first background objects are optionally visually less highlighted (e.g., dimmed, blurred, and / or displayed with increased transparency) than one or more second background objects, and one or more third background objects are discontinued. As referred to herein, visual salience of virtual content optionally refers to the display of one or more portions of the virtual content with one or more visual characteristics such that the virtual content is optionally distinct and / or visible relative to three dimensions as perceived by a user of the computer system. In some embodiments, the visual salience of virtual content has one or more characteristics described in connection with displaying virtual content at immersion levels above and / or below an immersion threshold. For example, the computer system optionally displays distinct virtual content with one or more visual characteristics having respective values, such as virtual content displayed at a certain opacity and / or brightness level. The opacity levels, for example, optionally, are 0% opacity (e.g., corresponding to invisible and / or fully translucent virtual content), 100% opacity (e.g., corresponding to fully visible and / or non-translucent virtual content), and / or other respective percentages of opacity corresponding to a discrete and / or continuous range of opacity levels from 0% to 100%.Decreasing the visual prominence of a portion of the virtual content optionally includes, for example, decreasing the opacity of one or more portions of the portion of the virtual content to 0% opacity or to an opacity value lower than the current opacity value. Increasing the visual prominence of a portion of the virtual content optionally includes, for example, increasing the opacity of one or more portions of the portion of the virtual content to 100% opacity or to an opacity value higher than the current opacity value. Similarly, decreasing the visual prominence of the virtual content optionally includes decreasing the brightness level of one or more portions of the virtual content (e.g., toward a fully dimmed visual appearance at a 0% brightness level or another brightness value lower than the current brightness level), and increasing the visual prominence of the virtual content optionally includes increasing the brightness level (e.g., toward a fully brightened visual appearance at a 100% brightness level or another brightness value higher than the current brightness level). It is understood that additional or alternative visual characteristics are optionally included in modifying visual saliency (e.g., saturation, where increasing saturation increases visual saliency and decreasing saturation decreases visual saliency; blur radius, where increasing blur radius decreases visual saliency and decreasing blur radius increases visual saliency; contrast, where increasing contrast value increases visual saliency and decreasing contrast value decreases visual saliency). Modifying the visual saliency of an object can include modifying multiple different visual characteristics (e.g., opacity, brightness, saturation, blur radius, and / or contrast). Furthermore, when the visual saliency of a first object is increased relative to the visual saliency of a second object, the change in visual saliency can be produced by increasing the visual saliency of the first object or decreasing the visual saliency of the second object, increasing the visual saliency of both objects while increasing the first object more than the second object, or decreasing the visual saliency of both objects without decreasing the first object more than the second object. It is also understood that the foregoing discussion of modifying visual saliency applies to the embodiments described herein.

[0220] In some embodiments, while displaying virtual content such as virtual content 716 shown in FIG. 7C , such as an immersive virtual scene that optionally obscures background content (e.g., a representation of the user's real-world environment such as environment 702 shown in FIG. 7C ), the computer system optionally displays a geometric indication of a potential area of ​​interaction, such as virtual content 704 shown in FIG. 7C . In some embodiments, the visual indication is a circle, rectangle, and / or oval shape superimposed on a discrete area of ​​the user's physical environment (e.g., the floor and / or an area on the floor). The visual indication is optionally presented to the user to indicate an area (e.g., a discrete area) where the user is likely to interact (e.g., move around within), and thus indicates where potential spatial collisions between the user and real-world objects lie. In some embodiments, the visual indication indicates a boundary of a discrete area of ​​the physical environment (e.g., a boundary superimposed on a representation of a discrete area of ​​the physical environment), such as a discrete area of ​​environment 702 corresponding to virtual content 704 as shown in FIG. 7C . In some embodiments, the discrete region of the physical environment is larger or smaller than a corresponding visual indication corresponding to the discrete region of the physical environment. For example, the visual indication is optionally a geometric shape superimposed on a portion of a representation of a real-world floor, while the discrete region of the physical environment optionally corresponds to the entire floor and / or an area of ​​the floor visible from the user's current viewpoint, such as the floor of environment 702 as shown in FIG. 7C . In some embodiments, a prompt to clear physical objects from the discrete region of the physical environment is displayed simultaneously with the visual indication, such as virtual content 712 as shown in FIG. 7B and FIG. 7B1 .

[0221] In some embodiments, the computer system, via the display generation component, displays (802d) the virtual content at an immersion level above an immersion threshold, such as virtual content 716 shown in FIG. 7C , which includes displaying visual indications corresponding to distinct areas of the physical environment with which a user of the computer system is likely to interact while viewing the virtual content at an immersion level above the immersion threshold, and then replacing at least a portion of the representation of the distinct areas of the physical environment with the virtual content, e.g., replacing the representation of the physical environment with virtual content 716 as shown in FIG. 7D . For example, the first three-dimensional environment corresponds to a mixed reality environment including an immersive virtual experience that optionally includes one or more areas of virtual content. The one or more areas of virtual content, for example, optionally include 90% of the mixed reality environment, and the one or more areas without virtual content include the remaining 10% of the mixed reality environment. In some embodiments, the immersive virtual experience includes a virtual environment that completely or nearly completely occupies the field of view of a user of the computer system. In some embodiments, virtual content contained in the virtual environment completely occupies the user's field of view, while the user changes their physical position and / or orientation relative to the immersive virtual environment so as to remain surrounded by the virtual content. For example, the computer system optionally displays visual indications, such as circular or rectangular shapes superimposed over discrete areas of the user's physical environment (e.g., the floor), to indicate areas where the computer system anticipates possible interactions with the virtual content, and / or areas where the user is allowed to move while optionally remaining in the immersive experience, and / or areas where the computer system optionally allows the initiation of one or more functions. In some embodiments, the visual indication is initially displayed relative to the user and their position relative to the first three-dimensional environment (e.g., centered on the user's position and / or feet). In some embodiments, the visual indication is static. In some embodiments, the visual indication is animated or continues to animate over a period of time.In some embodiments, the visual indication is partially transparent such that the virtual or real-world ground or floor is at least partially visible through the visual indication. In some embodiments, at least a portion of the visual indication includes a representation or representations of the physical environment. In some embodiments, the visual indication is offset from the ground or floor such that the visual indication appears to be hovering in the air or has a height (e.g., 1, 3, 5, 10, 100, or 1000 cm) relative to the ground. In some embodiments, the visual indication remains visible while the distinct region of the three-dimensional environment is visible from the user's perspective. In some embodiments, the computer system stops displaying the visual indication after a threshold amount of time (e.g., 0.01, 0.1, 0.25, 0.5, 1, 2.5, 5, or 10 seconds) and displays virtual content in the distinct region. In some embodiments, the computer system does not display the visual indication if the first input corresponds to a request to display virtual content in the first three-dimensional environment at an immersion level below an immersion threshold. Temporarily displaying visual indications corresponding to distinct areas of the environment enhances user safety by urging the user toward distinct areas in the user's physical environment and preventing potential collisions with physical objects within the distinct areas.

[0222] In some embodiments, displaying via the display generation component a visual indication corresponding to a distinct region of the physical environment with which a user of the computer system is likely to interact while viewing the virtual content at an immersion level above the immersion threshold, such as a viewing area corresponding to the virtual content 704 shown in FIG. 7C (e.g., as described with respect to step(s) 802), includes, pursuant to determining that the user is located at a first location in the physical environment (804b), the visual indication corresponding to the distinct region is a first visual indication (804c) corresponding to the first region of the physical environment, such as the location of the virtual content 704 shown in FIG. 7D (804a). For example, the computer system optionally determines a position of the user relative to the physical environment, such as a position of a distinct part of the user (e.g., the user's head, the user's feet, and / or the user's torso) corresponding to the first location in the physical environment. In some embodiments, the computer system determines that the user's first location corresponds to a distinct region of the physical environment, referred to herein as a “physical viewing area.” For example, the computer system optionally determines that the user's first location at least partially intersects with and / or is within the physical viewing area. In some embodiments, the visual indication, referred to herein as a "viewing zone," has one or more characteristics described in step(s) 812. In some embodiments, the first region of the physical environment is defined relative to a portion of the user's viewpoint. For example, the computer system optionally determines that the first region of the physical environment corresponds to a portion (e.g., 5%, 10%, 15%, 20%, 25%, 30%, 35%, or 40%) of the user's field of view extending from the physical floor toward the physical ceiling or sky. In some embodiments, the region of the physical environment corresponds to a portion (e.g., 5%, 10%, 15%, 20%, 25%, 30%, 35%, or 40%) of the physical floor relative to the user's viewpoint (e.g., centered on the user's physical location, such as the user's feet).In some embodiments, the region is an area of ​​the physical environment that is visible to the user's viewpoint (0.01, 0.05, 0.1, 0.5, 1, 5, 10 m. 2 ) In some embodiments, the first region of the physical environment has a world-locked location.

[0223] In some embodiments, the computer system replacing (804d) a portion of the representation of the distinct region of the physical environment with virtual content includes replacing at least a portion of the representation of a first region of the physical environment with virtual content, such as illustrated by virtual content 716 in FIG. 7D . For example, the computer system optionally stops displaying said physical viewing area at least partially or completely, as described with respect to step(s) 802, and / or begins displaying virtual content greater than the immersion threshold. In some embodiments, the physical viewing area is potentially visible (e.g., via passive visual penetration, such as a sheet of transparent material), but the display of the virtual content obscures the visibility of the representation of the distinct region. For example, when a user moves to a first position in the physical environment (e.g., enters a viewing zone), the physical viewing area initially, optionally, consumes a lower region of the user's field of view, while the virtual content is visible.

[0224] In some embodiments, following a determination (804e) that the user is at a second location in the physical environment that is different from the first location, the visual indication corresponding to the distinct region is a second visual indication corresponding to a second region of the physical environment that is different from the first region of the physical environment, such as the virtual content 704 shown in FIG. 7C displayed at the second location as shown (804f). For example, the visual indication is optionally displayed at a position in the XR or VR environment that is different from the first position, optionally corresponding to a distinct portion of the user. In some embodiments, the computer system displays the visual indication in a distinct region of the physical environment that corresponds to a distinct portion of the user.

[0225] In some embodiments, the computer system replacing portions of the representation of the distinct region of the physical environment with virtual content includes replacing at least portions of the representation of a second region of the physical environment with virtual content (804g), such as virtual content 716 replacing physical object 706 as shown in FIG. 7D (e.g., the same as or similar to that described with respect to replacing a first region of the physical environment with virtual content). Replacing portions of the representation of the distinct region of the physical environment with virtual content based on a determination that the user is located at a distinct location within the physical environment provides a consistent visual experience despite variations in the user's distinct location, thereby reducing the likelihood that the user will erroneously interact with the virtual content and / or reducing the need for inputs to reorient the virtual content relative to the distinct location.

[0226] In some embodiments, visual indications corresponding to distinct areas of the physical environment with which a user of the computer system is likely to interact are displayed (806) in association with the floor of the physical environment, such as the virtual content 704 as shown in FIG. 7C . For example, the viewing area (e.g., the visual indication) optionally corresponds to a portion of the floor of the user's physical environment, such that the user is visually guided toward the floor of the physical environment. In some embodiments, the portion of the floor is a circular, rectangular, or other shaped area of ​​the floor of the physical environment, optionally centered around the user's feet. Displaying visual indications associated with distinct areas of the physical environment provides information about potential spatial collisions with the physical environment while simultaneously viewing the virtual content, thus improving user safety.

[0227] In some embodiments, the visual indication has a first shape, and the visual indication is at least partially translucent (808), such as virtual content 704 as shown in FIG. 7C . For example, the visual indication is optionally a ring-shaped graphic overlaid on a representation of the user's physical floor, optionally indicating a boundary of a visibility zone, and / or optionally displayed with a discrete level of translucency (e.g., 5%, 10%, 15%, 20%, 25%, 35%, 45%, 60%, or 75% translucency). In some embodiments, the visual indication has one or more characteristics as described in method 1000. Displaying the visual indication with partial translucency reduces visual obstruction of the representation of the physical environment and, therefore, reduces the likelihood of the user undesirably colliding with portions of the physical environment.

[0228] In some embodiments, the first shape is elliptical and has a first, discrete diameter, and the visual indication includes a plurality of shapes including the first shape and a second shape other than the first shape, the second shape having a second diameter different from the first diameter (810), such as an elliptical version of the virtual content 704 as shown in FIG. 7C . In some embodiments, the visual indication includes a plurality of concentric shapes (e.g., rings). In some embodiments, the plurality of shapes is centered on a discrete position of the user. In some embodiments, the plurality of shapes is animated similarly to that described in step(s) 812. For example, the plurality of concentric shapes optionally emanate from a discrete position of the user. Displaying a visual indication with a plurality of shapes draws the user's attention toward discrete areas of the physical environment, thus reducing the likelihood of the user undesirably colliding with portions of the physical environment.

[0229] In some embodiments, displaying, via the display generation component, a visual indication corresponding to a distinct area of ​​the physical environment with which a user of the computer system is likely to interact includes displaying an animation of a boundary of the visual indication, such as the animation of virtual content 704 shown in FIG. 7C expanding from a first position, such as the position of virtual content 704 shown in FIG. 7C in the three-dimensional environment corresponding to a distinct portion of the user, to a second position in the three-dimensional environment that is different from the first position (812). In some embodiments, the visibility zone (e.g., the visual indication corresponding to a distinct area of ​​the physical environment of likely user interaction) has one or more characteristics of the animation as described in step(s) 802. For example, in response to a first input corresponding to a request to display virtual content, such as virtual content 716 shown in FIG. 7C , at an immersion level greater than an immersion threshold, the computer system optionally initially displays a visual indication having a boundary of a first shape and a first size, such as a first boundary and a first size (e.g., a relatively small circle centered on the user and / or the user's feet) of virtual content 704 shown in FIG. 7C , which visual indication optionally expands over time to a boundary of a second shape (optionally similar to the first shape) having a relatively larger size (e.g., a relatively larger circle), such as a second size of virtual content 704 shown in FIG. 7C . In some embodiments, the animation includes continuing to expand the boundary toward the outer edges of the user's viewpoint or a maximum size defined by the computer system. In some embodiments, the animation additionally includes visual effects, such as glowing effects, blurring effects, changes in translucency, lighting effects described in step(s) 814, and / or changes in brightness. In some embodiments, the boundary of the visual indication is continuously animated (e.g., expanded) until it reaches the outer edge and / or maximum size of the user's viewpoint, such as the animation of virtual content 704 shown in FIG. 7C.Displaying a visual indication along with the animation draws the user's attention toward a particular area of ​​the physical environment, thus reducing the likelihood of the user undesirably colliding with parts of the physical environment.

[0230] In some embodiments, the animation includes visual effects applied to surfaces of individual regions of the physical environment with which a user of the computer system is likely to interact (814), such as visual effects applied to virtual content 704 as shown in FIG. 7C . For example, the visual effects optionally have one or more characteristics as described in step(s) 812, such as simulated lighting effects optionally applied to surfaces of the representation of the physical viewing area (e.g., the floor, surfaces of individual objects positioned on the floor, and / or physical walls). In some embodiments, the simulated lighting effects are based on one or more virtual light sources positioned and directed toward each position in the physical environment. For example, the individual virtual light sources are optionally visible or invisible and oriented perpendicular to the surfaces of the representation of the physical viewing area. The inclusion of visual effects applied to surfaces of individual regions of the physical environment draws user attention to the contours of each object contained within the individual regions and the individual regions, thereby improving user safety.

[0231] In some embodiments, while animating, via the display generation component, the boundaries of the visual indications corresponding to distinct regions of the physical environment, pursuant to a determination that the visual indications have been animated for a period longer than a threshold time period (e.g., 0.01, 0.05, 0.1, 0.5, 1, 5, 10, 15, 30, or 60 seconds), the computer system stops animating the boundaries of the visual indications (816), such as stopping the animation of the virtual content 704 as shown in FIG. 7C . For example, the animation optionally stops gradually or abruptly after the visual indications have animated beyond the threshold amount of time. In some embodiments, the visual indications continue to be displayed with a default appearance (e.g., including one or more characteristics of the visual effect of the animation described in step(s) 812) after the threshold time has elapsed. In some embodiments, the visual indications continue to be displayed with a visual appearance after the animation has stopped that matches the appearance of the visual effect at the time the animation was stopped. Stopping the animation visually guides the user away from a particular area of ​​the physical environment, thereby improving focus on the displayed virtual content, and optionally indicates that particular inputs that optionally did not initiate the performance of a function(s) while the animation was optionally in progress are now operable to optionally initiate the performance of a function(s).

[0232] In some embodiments, displaying the virtual content at an immersion level higher than the immersion threshold via the display generation component includes replacing a second representation of a second distinct region of the representation of the physical environment corresponding to an upper region of the user's viewpoint with a first portion of the virtual content (818a), such as virtual content 716 as shown in FIG. 7C to virtual content 818b as shown in FIG. 7D. For example, the second distinct region of the representation of the physical environment optionally includes a portion of an upper region of the user's field of view (e.g., 0.1, 1, 3, 5, 10, 15, 30, 45, 90, or 120 degrees). In some embodiments, replacing the second representation of the second distinct region includes reducing the visual salience of the second representation of the second distinct region (e.g., ceasing to display and / or increasing its individual translucency). In some embodiments, the remaining (e.g., unreplaced) portions of the representation of the physical environment are maintained while the replacement is occurring. For example, the replacing optionally includes an animation that gradually reduces the distinct visual salience of the second distinct region in a first direction (e.g., from the top of the user's field of view downward toward the bottom of the user's field of view) while maintaining the distinct visual salience of the remainder of the representation of the physical environment. Additionally or alternatively, the visual salience of the first virtual content is optionally increased while the replacement is taking place. For example, the animation includes gradually increasing the visual salience of the virtual content replacing the second representation of the second distinct region.

[0233] In some embodiments, after replacing the second representation of the second distinct region, the computer system replaces (818c) a third representation of a third distinct region of the representation of the physical environment that corresponds to a lower region of the user's viewpoint, lower than an upper region of the user's viewpoint, with a second portion of virtual content, such as virtual content 716 shown in FIGS. 7C-7D . For example, the replacement of the third representation of the third distinct region of the representation of the physical environment is optionally initiated pursuant to a determination that one or more criteria are met, including a criterion that is met when a threshold amount of time (e.g., 0.01, 0.05, 0.1, 0.5, 1, 5, 10, or 15 seconds) has elapsed since the replacement of the second representation of the second distinct region was initiated or completed. In some embodiments, the one or more criteria include a criterion that is met when a user input is received that includes a request to cease displaying the third distinct region (e.g., an input including actuation of a physical button, selection of a selectable affordance that ceases displaying the third distinct region, and / or movement detected within the distinct region of the physical environment). In some embodiments, the replacement of the third representation of the third distinct region has one or more characteristics of the replacement of the second representation of the second distinct region. Additionally or alternatively, the visual prominence of the first virtual content is optionally increased while the replacement is occurring. For example, the animation includes gradually increasing the visual prominence of the virtual content replacing the second representation of the third distinct region. In some embodiments, the animation described herein is included in an animation that successively replaces the representation of the physical environment from an upper portion of the user's field of view to a lower portion of the user's field of view. The successively replacing the distinct regions of the representation of the physical environment with distinct virtual content visually guides the user's attention toward a lower region of the user's field of view, thereby reducing the likelihood of spatial collisions between the user of the computer system and physical objects visible within the lower region of the user's field of view.

[0234] In some embodiments, in response to detecting a first input via one or more input devices and following a determination that one or more criteria are met, including criteria met when the first input corresponds to a request to display virtual content at an immersion level greater than the immersion threshold, the computer system, via the display generation component, displays (820) individual virtual content indicating that the virtual content will be displayed at an immersion level greater than the immersion threshold, such as the virtual content 712 shown in FIGS. 7B and 7B1. For example, the computer system optionally displays a virtual object including individual virtual content (e.g., text and / or a graphical icon) indicating that immersive virtual content is loaded. In some embodiments, the individual virtual content displays a description of the virtual content. In some embodiments, the individual virtual content includes one or more selectable options associated with the display of the virtual object and / or the individual virtual content, as described in further detail below. In some embodiments, the individual virtual content is displayed if one or more criteria are met, as described in step(s) 824. Displaying separate virtual content that indicates that the virtual content will be displayed at an immersion level greater than the immersion threshold reduces the likelihood that a user will accidentally initiate the display of the virtual content, thereby reducing the processing required to initiate such an erroneous display and preventing the need for input to dismiss the virtual content.

[0235] In some embodiments, the one or more criteria are met (822) regardless of the number of times the virtual content is displayed at an immersion level above the immersion threshold, such as the number of times virtual content 716 as shown in FIG. 7C is displayed. For example, the virtual object described in step(s) 820 is displayed every time in response to the first input, optionally regardless of a previous history of interactions associated with the virtual content (e.g., the number of times an input similar to the first input was received and / or the number of times virtual content or other virtual content at an immersion level above the immersion threshold was displayed). In some embodiments, as described in step(s) 820, the virtual object includes one or more selectable options (e.g., including "Confirm" and / or including "Don't Show Again"). In some embodiments, in response to detecting an input that selects a particular affordance included in the particular virtual content, the computer system begins displaying the virtual content (e.g., the immersive visual experience described in step(s) 802). In some embodiments, the one or more criteria include a criterion that is met if the user has not previously selected a particular affordance (e.g., "don't show again") included in the particular virtual content (e.g., as described with respect to step(s) 824, the computer system optionally forgoes displaying the virtual object (e.g., the particular virtual content indicating that the virtual content is to be displayed at an immersion level higher than the immersion threshold). Displaying the particular virtual content regardless of the number of times the virtual content is displayed ensures that the user has consistent expectations of what will be displayed in response to a first input, thereby reducing the likelihood that the user will accidentally direct their input towards the virtual content.

[0236] In some embodiments, in response to detecting a first input via one or more input devices and following a determination that one or more criteria are not met (e.g., as described in step(s) 822), the computer system forgoes displaying the individual virtual content via the display generation component (824), such as the aforementioned display of virtual content 716 shown in FIG. 7C . For example, the one or more criteria include criteria that are not met when the user recently interacted with the individual virtual content (e.g., individual virtual object) as described in step(s) 820. In some embodiments, the one or more criteria include criteria that are not met based on recency of the interaction as described in step(s) 826. For example, the computer system optionally forgoes displaying the individual virtual content, such as a virtual object and / or virtual content, if the one or more criteria are not met. As another example, the computer system optionally determines that the user recently provided an input requesting display of the virtual content at an immersion level greater than a threshold level of immersion, and, in response, forgoes displaying the individual virtual content. Forgoing the display of the individual virtual content reduces the user input required to stop the display of the individual virtual content.

[0237] In some embodiments, the one or more criteria include criteria that are met based on the recency of a user of the computer system's previous interaction with the virtual content (826). For example, the computer system optionally forgoes displaying the virtual content 712 as shown in Figures 7B and 7B1, or forgoes displaying the individual virtual content as shown in Figure 7A, if the computer system detects that the user has recently interacted with the virtual content, such as a request to display the virtual content 712 as shown in Figures 7B and 7B1 (e.g., initiating loading of the virtual content, dismissing the virtual content, and / or moving to and / or from the individual virtual content). In some embodiments, the one or more criteria include individual criteria that are met when the user recently interacted with virtual content, such as the virtual content 716 shown in Figure 7C, that was displayed at an immersion level greater than an immersion threshold, similar or the same as described in step(s) 802. In some embodiments, the one or more criteria include a criterion that is met if the user has not provided such a recent interaction within a threshold amount of time (e.g., 0.05, 0.1, 0.5, 1, 5, 10, 50, 100, or 500 hours) of receiving the first input, such as a threshold amount of time in detecting movement of user 701 to a position as shown in Figures 7B and 7B1. Including a criterion that is met based on the recency of a user of the computer system's previous interaction with virtual content reduces the display of redundant individual virtual content that the user may not want to see.

[0238] In some embodiments, the one or more criteria include a criterion that is satisfied based on the recency of detecting a previously received individual input via one or more input devices corresponding to a request to display individual virtual content at an immersion level greater than an immersion threshold in an individual region of the physical environment (828), such as the recency of detecting an input of hand 703A directed at selectable option 712-1, e.g., as described in steps 824-826. In some embodiments, the previously received individual input is the same as the first input described with respect to step(s) 802. In some embodiments, the previously received individual input is a different input, such as an input for displaying recently displayed virtual content (e.g., the immersive visual experience(s) described in step(s) 802). In some embodiments, the recency of detecting the individual input is based at least in part on the individual physical environment in which the user was located when the individual input was detected. For example, the one or more criteria optionally include a criterion that is satisfied when the individual input is received while the user is in an individual physical environment (e.g., a room) that is the same as the current physical environment (e.g., the same room). In some embodiments, the one or more criteria include a criterion that is not satisfied when the user is in a different individual physical environment, such as a first room, and when the individual input is received that differs from the user's current physical environment, such as a second room that is different from the first room. In some embodiments, the one or more criteria include a criterion that is satisfied when the degree to which the current physical environment resembles the individual physical environment in which the user was present when the individual input was received is greater than a threshold amount (e.g., 5%, 10%, 15%, 25%, 35%, 50%, 65%, 75%, or 90%). For example, the current physical environment is optionally a first room, and the individual physical environment optionally corresponds to a doorway connected to the first room and a second, different room. Including a criterion that is satisfied based on recency of detecting individual input corresponding to a previously received request to display individual virtual content reduces the display of redundant individual virtual content due to the recency of users providing such individual input while in similar physical environments.

[0239] In some embodiments, after displaying visual indications corresponding to distinct areas of the physical environment with which a user of the computer system is likely to interact, replacing at least a portion of a representation of a distinct area of ​​the physical environment, such as physical object 706, with virtual content includes maintaining display of at least a portion of a representation of a distinct area of ​​the physical environment, such as virtual content 716 shown in FIG. 7D (830). For example, the computer system optionally maintains visibility of at least a portion of the physical viewing area and optionally replaces a different portion of the physical viewing area with virtual content (e.g., part of an immersive visual experience) similar to that described in step(s) 802. In some embodiments, representations of physical objects in the physical viewing area remain partially or fully visible as part of maintaining and replacing distinct portions of the physical viewing area with virtual content. For example, the computer system optionally replaces representations of the physical world from the top of the user's field of view toward the bottom of the user's field of view, optionally partially intersecting with physical objects (e.g., toys, blocks, sofas, and / or tables) such that the tops of the physical objects are replaced with virtual content while the bottoms of the representations of the physical objects remain visible. In some embodiments, the representation of the physical viewing area is maintained, but with reduced visual prominence (e.g., with increased translucency), at least in part because the virtual content that begins to replace the representation of the physical viewing area is displayed with reduced visual prominence (e.g., with a relatively increased amount of translucency). In some embodiments, individual portions of the representation of the physical viewing area (e.g., representations of physical objects) are displayed with reduced prominence, while other remaining portions of the physical viewing area are replaced with virtual content. Thus, the computer system optionally preserves visibility of one or more portions of the user's physical environment at least part of the time. In some embodiments, maintaining at least a portion of the representation of the physical environment is discontinued if one or more criteria are met, as further described in step(s) 830.In some embodiments, the computer system detects the presence of a physical object within the physical viewing area and forgoes replacing the representation of the physical object and / or a distinct portion of the representation of the physical environment with virtual content. In some embodiments, if the computer system does not detect a physical object within the distinct portion of the physical viewing area, the computer system replaces the representation of the distinct portion of the physical viewing area with virtual content. In some embodiments, display of a first representation of a first distinct region that includes the physical object is maintained, while the representation of a second distinct region is replaced with virtual content. Maintaining at least partial display of the representation of the physical environment while replacing the representation of the physical environment with virtual content visually emphasizes the presence of physical objects in the user's environment, thereby reducing potential physical collisions with such physical objects.

[0240] In some embodiments, following a determination that a portion of the representation of a distinct region of the physical environment has remained visible for an amount of time greater than a threshold amount of time (0.01, 0.05, 0.1, 0.5, 1, 5, 10, or 15 seconds) while maintaining display of at least a portion of the representation of the distinct region of the physical environment, such as a portion of environment 702 not consumed by virtual content 716 as shown in Figure 7C, the computer system replaces (832) at least a portion of the representation of the distinct region of the physical environment with virtual content at an immersion level greater than an immersion threshold, as indicated by replacement with virtual content 716 as shown in Figure 7D. For example, following a determination that one or more criteria are met, including a criterion met when at least a portion of the physical viewing area has remained visible for more than a threshold amount of time while maintaining display of the portion of the physical viewing area, the computer system optionally begins replacing that remaining portion of the physical viewing area with virtual content at an immersion level greater than an immersion threshold. In some embodiments, the replacing includes displaying an animation of the virtual content having one or more characteristics of the animations described in step(s) 812 and step(s) 818. Replacing at least a portion of the representation of a discrete area of ​​the physical environment after the representation has been visible for more than a threshold amount of time improves the user's orientation of the physical world relative to the virtual content, thereby reducing the user's input to manually cause such replacement and orientation and reducing the likelihood of collisions between the user and the physical environment.

[0241] In some embodiments, the representation of the discrete region of the physical environment includes (834) a portion of the physical environment corresponding to a bottom region of a viewpoint of a user of the computer system, such as a portion of the environment 702 not consumed by virtual content 716 as shown in FIG. 7C , e.g., as described in step(s) 802 and / or step(s) 828. For example, the region of the user's viewpoint corresponding to the physical viewing area optionally remains visible for at least a period of time while maintaining the display of at least a portion of the physical viewing area as described in step(s) 828. In some embodiments, the bottom region corresponds to any discrete point of the physical environment below a height threshold (e.g., 0.01, 0.025, 0.05, 0.25, 0.5, 1, 2.5, or 5 meters). Additionally or alternatively, the lower region optionally corresponds to an amount of the user's field of view (e.g., 0.1, 1, 3, 5, 10, 15, 30, 45, 90, or 120 degrees of the lower portion of the user's field of view). In some embodiments, the extent to which the representation of the distinct region of the physical environment consumes the user's field of view is variable based on the orientation of a second part of the user's body (e.g., the head) relative to the physical environment. For example, the computer system optionally displays the representation of the distinct region of the physical environment in its entirety (e.g., without displaying immersive virtual content, or with a minimal amount of immersive virtual content) while the second part of the user's body is oriented toward a boundary of the physical viewing region (e.g., the floor). In response to optionally detecting that a second one of the portions moves in a second orientation (e.g., corresponding to a field of view that includes a portion of a discrete area of ​​the physical environment replaced by the immersive visual content), the computer system optionally simultaneously displays at least a portion of a representation of the immersive virtual content and / or the physical environment according to a boundary of the displayed virtual content at an immersion level higher than the immersion threshold, and a remaining portion of the physical viewing area not consumed by the virtual content.Maintaining display of a lower region of a computer system's representation of a user's physical environment in which the user is likely to move, sit, and / or stand while displaying virtual content having an immersion level greater than an immersion threshold improves the user's awareness of the user's physical surroundings, thereby reducing the likelihood of physical collisions with the environment and reducing the need to stop displaying virtual content in the lower region to gain such awareness.

[0242] In some embodiments, in response to detecting a first input via one or more input devices, the computer system, via a display generation component, displays (836) a selectable option selectable to forgo displaying a visual indication in response to a future input corresponding to a request to display virtual content at an immersion level greater than the immersion threshold, such as selectable option 712-2 shown in FIG. 7D . For example, as described with respect to step(s) 822, the computer system optionally displays multiple selectable options to indicate a user's intent to forgo displaying virtual content, such as a visual indication, in the future. The computer system optionally displays selectable options for forgoing displaying a visual indication in the future in response to the first input, and optionally detects an input selecting a selectable affordance. In some embodiments, in response to detecting a second input corresponding to a second request to display virtual content at an immersion level greater than the immersion threshold, and in accordance with a determination that one or more criteria have been met, including criteria met when a user of the computer system previously selected the selectable option, the computer system forgoes displaying a visual indication (e.g., a geometric shape). In some embodiments, the display of the visual indication is not foreclosed but instead modified. For example, the visual indication is optionally displayed with a modified appearance (e.g., increased translucency, added blur effect, and / or decreased brightness) in response to the second input if one or more criteria are met. By presenting selectable options and then forgoing the display of the visual indication, the need for a future input to discontinue the display of the visual indication is reduced.

[0243] In some embodiments, in response to detecting the first input via the one or more input devices, the computer system, via the display generation component, displays (838) a second visual indication distinct from the visual indication, indicating that a process has begun to determine one or more characteristics of the user's physical environment, including distinct regions of the physical environment, such as an indication of determining characteristics of environment 702 as shown in FIG. 7D . For example, the computer system optionally displays a progress indicator to communicate that the computer system is assessing the physical environment. In some embodiments, the progress indicator is a graphical icon (e.g., a gradually fading and / or filling ring) that is modified according to the progress of the assessment. In some embodiments, the progress indicator includes a grid overlaid on a representation of the physical environment that follows the contours of the physical environment (e.g., objects, floors, and / or walls). In some embodiments, the second visual indication is displayed simultaneously with the visual indication(s) described in step(s) 802. In some embodiments, the second visual indication is displayed until the assessment of the physical environment is completed. In response to the completion of the assessment, the display of the second visual indication is stopped and the display of the visual indication is started. In some embodiments, one or more characteristics of the physical environment, such as the floor area of ​​the physical environment, the presence of objects in the physical environment, the location of walls in the physical environment, and / or the contours of surfaces in the physical environment. Displaying an indication of the user's assessment of the physical environment indicates that the computer system, optionally, has not yet responded to some user input(s), thereby reducing erroneous user input(s).

[0244] In some embodiments, while displaying the visual indication via the display generating component, the computer system displays (840a) via the display generating component selectable options that can be selected to modify the visual indication, such as selectable option 1714-1 shown in Figures 7B and 7B1. For example, the selectable options are, optionally, shapes that can be selected to scale the visual indication in one or more directions.

[0245] In some embodiments, while displaying the selectable options via the display generating component, the computer system receives (840b) a second user input via one or more input devices, including a selection of a selectable option and a request to move the selectable option, such as input from hand 703A shown in FIGS. 7B and 7B1. For example, the computer system optionally detects an air pinch gesture (e.g., convergence and maintenance of contact of the user's index finger and thumb) performed with a first part of the user (e.g., hand) while the user's attention is directed to the selectable option and movement of the first part of the user. The second user input optionally corresponds to a selection and movement performed with a pointing device (e.g., a mouse, stylus, and / or glove) or another air gesture (e.g., squeezing the user's hand while attention is directed to the selectable option and scaling a visual indication according to movement of the hand until a similar squeezing of the hand is detected).

[0246] In some embodiments, in response to receiving the second user input, the computer system modifies (840c) the visual indication according to the movement of the selectable option, as indicated by the virtual content 704 as shown in Figures 7B and 7B1 compared to that shown in Figure 7C. For example, the computer system optionally detects leftward and upward movement of an air pinch gesture while the user's attention is directed to a selectable option superimposed on the upper left corner of the visual indication (e.g., having a half-rectangle shape or another shape), and optionally enlarges the visual indication and, optionally, moves the selectable option according to the movement (e.g., away from the user to the user's left or in another direction). In some embodiments, the visual indication is scaled along one or more respective dimensions according to the movement. In some embodiments, the visual indication is scaled equally in all directions according to the movement. Presenting selectable options for modifying the visual indication allows a user of the computer system to reduce visual conflict between the visual indication and individual content, such as virtual content and / or representations of the physical environment, and indicates to the computer system potential areas of physical interaction so that the computer system can determine how to present the virtual content and modify the visual salience of the virtual content and / or representations of the user's physical environment accordingly.

[0247] In some embodiments, visual indications corresponding to distinct areas of the physical environment with which a user of the computer system is likely to interact are displayed (842) after detecting one or more characteristics (e.g., size, shape, and / or location of one or more physical objects) of the user's physical environment, such as environment 702, including distinct areas of the physical environment, such as virtual content 704 shown in FIG. 7C . For example, as described with reference to step(s) 836. In some embodiments, the process is initiated and / or completed prior to receiving a first input requesting the display of virtual content at an immersion level greater than an immersion threshold. For example, the computer system optionally initiates and / or completes the process in response to detecting that the user has entered an (optionally new) physical environment (e.g., a room or other physical space). In some embodiments, the process is initiated and / or completed in response to the first input. In some embodiments, the process includes determining one or more characteristics of the physical environment or a portion of the physical environment. For example, the computer system optionally determines one or more characteristics of a first portion of the physical environment, optionally including a portion of the physical environment in front of the user's current point of view and optionally including a portion behind the user's current point of view (e.g., 0.01, 0.05, 0.1, 0.5, 1, 5, 10, 15, 25, 50, or 100 meters behind the user), but not including the entirety of the physical environment behind the user's current point of view. In some embodiments, the process is initiated as described in the previous embodiment and continues simultaneously while the user is viewing the virtual content at an immersion level above the immersion threshold. Displaying a visual indication after the computer system has initiated the process of determining the characteristic(s) of the physical environment ensures that the computer system is aware of the physical environment, thereby allowing it to display visual indications in discrete areas of the physical environment corresponding to areas of potential interaction, thereby improving the user's awareness of the physical environment.

[0248] It should be understood that the particular order in which the operations in method 800 are described is merely exemplary and does not indicate that the described order is the only order in which the operations may be performed. Those skilled in the art will recognize various ways to reorder the operations described herein.

[0249] 9A-9E illustrate an example of a computer system that reduces the visual salience of immersive virtual content and displays areas of high interaction potential, according to some embodiments.

[0250] 9A illustrates a reduction in the visual salience of virtual content according to an embodiment of the present disclosure. Figure 9A illustrates computer system 101 displaying, via a display generating component (e.g., display generating component 120 of FIG. 1 ), a three-dimensional environment 902 from the perspective of user 901 shown in an overhead view (e.g., facing the back wall of the physical environment in which computer system 101 is located). As described above with reference to FIGS. 1-6 , computer system 101 optionally includes a display generating component (e.g., a touchscreen) and multiple image sensors (e.g., image sensor 314 of FIG. 3 ). The image sensors optionally include one or more of a visible light camera, an infrared camera, a depth sensor, or any other sensor that computer system 101 could use to capture one or more images of a user or a portion of a user (e.g., one or more of the user's hands) while the user interacts with computer system 101. In some embodiments, the user interfaces shown and described below may also be realized on a head-mounted display that includes display generating components that display the user interface or three-dimensional environment to the user, and sensors (e.g., external sensors facing outward from the user) for detecting movements of the physical environment and / or the user's hands, such as movements that are interpreted by the computer system as gestures, such as air gestures, and / or the user's line of sight (e.g., internal sensors facing inward toward the user's face).

[0251] 9A , computer system 101 captures one or more images of the physical environment surrounding computer system 101 (e.g., operating environment 100), including one or more objects within the physical environment surrounding computer system 101. In some embodiments, computer system 101 displays a representation of the physical environment within three-dimensional environment 902, or portions of the physical environment are visible via display generation component 120 of computer system 101. For example, three-dimensional environment 902 includes portions of the left and right walls, ceiling, and floor within user 901's physical environment.

[0252] 9A , three-dimensional environment 902 also includes virtual content, such as virtual content 904. Virtual content 916 optionally has one or more characteristics described in connection with virtual content 904, and optionally has one or more characteristics of the virtual environments and / or immersive visual experiences described with reference to Figures 7A-7D . In some embodiments, virtual content 916 corresponds to a virtual environment and has one or more characteristics of the virtual environments described with reference to Figures 7A-7D . In some embodiments, virtual content 904 is not yet shown or is displayed with a level of translucency such that virtual content 904 is not visible.

[0253] In some embodiments, while displaying virtual content 916 at an immersion level above an immersion threshold, as described with reference to method 800 and FIGS. 7A-7D , a user of computer system 101 optionally provides an input to stop displaying the virtual content at an immersion level above the immersion threshold. For example, while displaying an immersive visual experience such as that shown in FIG. 7D , computer system 101 optionally detects an input including a modification of the user's viewpoint, such as movement of user 901 toward and / or through a boundary of a viewing area associated with virtual content 904 (e.g., corresponding to virtual content 704 and viewing area described with reference to FIGS. 7A-7D ). In some embodiments, the distinct positions optionally correspond to distinct locations within the viewing area as described with reference to FIGS. 7A-7D , such as a center of the viewing area, a boundary of the viewing area, and / or a corner of the viewing area. In some embodiments, the distinct positions have world-locked locations such that the distinct positions correspond to distinct physical locations within the physical environment. In some embodiments, the discrete positions correspond to boundaries of the viewing area.

[0254] In some embodiments, in response to movement away from the discrete position and / or following a determination that the user's modified viewpoint does not correspond to the discrete position, computer system 101 begins reducing the visual salience of at least a portion of virtual content 916. For example, while displaying an immersive visual experience (e.g., virtual content 916, optionally corresponding to a virtual scene of a campsite, a ranch, and / or a lake), in response to an input including user 901 moving to a second physical location outside the viewing area (corresponding to 904), computer system 101 begins reducing the visual salience of such immersive visual experience. The reduction of visual salience optionally includes any suitable manner of modifying the visual appearance and / or display of virtual content 916, as described in further detail below. In some embodiments, the reducing includes ceasing to display a portion of virtual content 916. In some embodiments, the reducing includes modifying the translucency of a portion of virtual content 916. Additional or alternative details regarding reducing the visual salience of virtual content 916 are described with reference to method 1000.

[0255] 9A illustrates modifying the visual salience of virtual content 916 according to examples of the present disclosure. For example, user 901 moves away from a viewing area corresponding to virtual content 904, which is visible in an overhead view and is not displayed by computer system 101. In some embodiments, virtual content 904 is not displayed until the current viewpoint corresponds to a second location outside the discrete area of ​​the physical environment corresponding to virtual content 904 (e.g., outside the viewing area). For example, while the user's position is within the viewing area, computer system 101 optionally forgoes displaying virtual content 904, and pursuant to a determination that the user's viewpoint has shifted to a second location outside the viewing area, computer system 101 optionally begins displaying virtual content 904 (e.g., corresponding to virtual content 704). In some embodiments, computer system 101 determines that the user has moved to a second location within the viewing area corresponding to virtual content 904 and forgoes reducing the visual salience of the virtual content. For example, computer system 101 optionally detects when the user moves to a location within the viewing area so that the user's feet remain within the viewing area, and maintains the display of virtual content 916 accordingly.

[0256] In some embodiments, the virtual content 904 corresponds to a world-locked location. For example, the computer system 101 maintains an understanding of the shape and / or orientation of the virtual content 904 relative to the user's physical environment even as the user's viewpoint shifts to an orientation and / or location inside and / or outside the boundaries of the virtual content 904. Thus, from the user's viewpoint, the virtual content 904 optionally has a fixed position within the environment 902, similar to a physical object such as a rug placed on the floor of the environment 902.

[0257] In some embodiments, in response to an input to initiate a reduction in the visual salience of the virtual content 916, the computer system 101 initiates a reduction in the visual salience of at least a portion of the virtual content 916. For example, the computer system 101 optionally detects an input including movement of the user 901 outside of a viewing area, and in response, the computer system 101 optionally modifies and / or stops displaying the portion of the virtual content 916. In some embodiments, the virtual content 916 includes one or more virtual objects (e.g., virtual windows including one or more user interfaces of respective applications, such as a communication application, a media playback application, and / or a mapping application), one or more representations of virtual objects (e.g., a virtual pillar, a virtual car, and / or a virtual tree), and / or an immersive visual experience (e.g., an immersive visual scene, such as an immersive beach, forest, and / or space scene). In some embodiments, the computer system 101 interprets the movement as a request to reduce the visual salience of at least a portion of the virtual content 916, such as a request to start looking at a portion of the physical environment and / or a request to stop displaying the virtual content entirely. In some embodiments, modifying the visual salience of virtual content 916 to an immersion level below the immersion threshold optionally includes ceasing display of the virtual content. For example, computer system 101 optionally ceases displaying a first portion of virtual content 916, such as portion 915. Portion 915 optionally includes virtual content that is displayed with reduced visual salience (e.g., displayed at 100% transparency and / or is no longer displayed), so that user 901 can optionally see physical object 910.

[0258] In some embodiments, the computer system optionally applies one or more visual effects to the portion 915 of the virtual content 916 to indicate a reduction in visual salience of the portion 915 of the virtual content 916. The one or more visual effects optionally include a blurring effect, a feathering effect, dimming, and / or increasing transparency applied uniformly or non-uniformly across the portion 915. For example, a left-most region of the portion 915, optionally with a pale edge, is displayed at a first transparency (e.g., 5, 10, 15, 20, 30, 40, 50, 60, 75, 90, or 95% transparency), and a second region to the right of the left-most region is displayed at a second, relatively lower transparency. In some embodiments, the non-uniformly applied visual effect includes a visual effect gradient (e.g., a gradient of increasing translucency from the left-most region to the right-most region of the portion 915 of the virtual content 916). The non-uniformity of the visual effect optionally provides a sense of progression in the reduction in visual salience.

[0259] In some embodiments, the direction of the reduction in visual salience of virtual content 916 and / or portion 915 is determined accordi...
