[0003] This application is a continuation-of-U.S. patent application No. 18 / 370,849, filed on September 20, 2023, and also claims priority to U.S. patent application No. 18 / 370,851, filed on September 20, 2023, U.S. patent application No. 18 / 370,853, filed on September 20, 2023, U.S. Provisional Patent Application No. 63 / 470,926, filed on June 4, 2023, and U.S. Provisional Patent Application No. 63 / 409,752, filed on September 24, 2022, each of which is hereby incorporated by reference in its entirety. Technical Field

[0004] The present disclosure generally relates to computer systems having display generation components and one or more input devices that provide computer-generated extended reality (XR) experiences, including but not limited to electronic devices that provide virtual reality and mixed reality experiences via the display generation components. Background Art

[0005] In recent years, the development of computer systems for virtual reality, augmented reality, and extended reality has increased significantly. Example augmented reality and extended reality environments include at least some virtual elements that replace or enhance the physical world. Input devices (such as cameras, controllers, joysticks, touch-sensitive surfaces, and touch screen displays) for computer systems and other electronic computing devices are used to interact with virtual / augmented / extended reality environments. Example virtual elements include virtual objects (including digital images, videos, text, icons, control elements (such as buttons), and other graphics).

[0006] However, methods and interfaces for interacting with environments that include at least some virtual elements (e.g., applications, augmented reality environments, mixed reality environments, virtual reality environments, and / or extended 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 desired results in a virtual / augmented / extended reality environment, and systems where virtual object manipulation is complex, cumbersome, and error-prone can place a significant cognitive burden on users and detract from the experience of the virtual / augmented / extended reality environment. Furthermore, these methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-powered devices. Summary of the Invention

[0007] Therefore, there is a need for computer systems with improved methods and interfaces for providing computer-generated experiences to users, thereby making the user's interaction with the computer system more efficient and intuitive for the user. The disclosed systems, methods, and user interfaces reduce or eliminate the above-mentioned drawbacks and other problems associated with user interfaces for computer systems having display generation components and one or more input devices. Such systems, methods, and interfaces optionally supplement or replace conventional systems, methods, and user interfaces for providing extended reality experiences to users. Such methods and interfaces reduce the amount, extent, and / or nature of inputs from the user by helping the user understand the connection between the inputs provided and the device's response to those inputs, thereby forming a more effective human-computer interface.

[0008] Therefore, it is desirable to have a computer system with an improved method and interface to provide a computer-generated experience to a user, thereby making the interaction between the user and the computer system more effective and more intuitive for the user. It is also desirable to have a computer system with an improved method and interface to provide a computer-generated experience to a user, thereby promoting better social interaction, etiquette, and information exchange with the surrounding environment when the user participates in various virtual reality and mixed reality experiences. Such methods and interfaces optionally supplement or replace conventional methods for providing a computer-generated reality experience to a user. Such methods and interfaces reduce the quantity, degree, and / or nature of the inputs from the user by helping the user understand the connection between the inputs provided and the device's response to these inputs, thereby forming a more effective human-computer interface. Such methods and interfaces also improve the user's experience, for example, by reducing errors, interruptions, and time delays caused by the lack of social cues and visual information for the user and others in the same physical environment when the user participates in the virtual reality experience and / or mixed reality experience provided by the computer system.

DETAILED DESCRIPTION

[0039] According to some embodiments, the present disclosure relates to a user interface for providing a computer-generated extended reality (XR) experience to a user.

[0040] The systems, methods, and GUIs described herein improve user interface interactions with virtual / augmented reality environments in several ways.

[0041] As disclosed herein, a computer system includes at least two display generation components, wherein a first display generation component faces a user and provides a three-dimensional computer-generated experience to the user, and a second display generation component faces away from the user and provides state information related to the user (e.g., movement of the user's eyes and / or other facial features; and / or changes in the appearance of the user's face and / or eyes) and / or the computer-generated experience currently being viewed by the user (e.g., metadata related to content being viewed by the user and an immersion level associated with the content). The first display generation component and the second display generation component are optionally two displays enclosed in the same housing of a head-mounted display device (HMD) and facing inward toward the user wearing the HMD and outward toward the physical environment surrounding the user, respectively. The second display generating component optionally provides real-time status information (e.g., real-time status information, optionally including status information with some computational and / or signal processing latency (e.g., latency of less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users)), the real-time status information including a visual representation of the portion of the user's body that is obscured by the first display generating component and including metadata related to content currently being shown to the user via the first display generating component and / or an immersion level associated with the content, so that one or more other people in the user's surrounding physical environment can see the visual information and metadata provided by the second display generating component and act accordingly, such as conversing with the user when appropriate while the user is viewing computer-generated content via the first display generating component, rather than unnecessarily avoiding interaction with the user or inappropriately interrupting the user. In some embodiments, as described herein, when displaying a representation of a portion of a user's body via the second display generating component as described herein, the computer system distinguishes between users that meet a first criterion and users that do not meet the first criterion. Specifically, the first criterion is used to distinguish between a primary or registered user of the computer system and a guest user of the computer system. In some embodiments, the computer system stores one or more images and models of parts of the registered user's body during the registration process, and subsequently uses the stored images and / or models to generate a representation of the parts of the registered user's body to indicate the real-time status of the registered user (e.g., the real-time status optionally includes the status of the registered user with some computational and / or signal processing delays (e.g., delays of less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or amounts that are imperceptible to most users)).In contrast, the computer system does not establish a set of images and / or models for the guest user, and optionally uses a generic image or a reduced-fidelity image and / or model for the guest user to generate a representation of a portion of the guest user's body to indicate the guest user's real-time status (e.g., the real-time status optionally includes status information of the guest user with some computational and / or signal processing delay (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users). Distinguishing the representation of the portion of the user's body based on whether the user is a registered user or a guest user alerts others in the surrounding environment to the identity of the person using the computer system when the person's face is significantly obscured by the presence of the first display generating component, and helps the person interact more appropriately with the person using the computer system, thereby avoiding misunderstandings, accidents, and / or errors. Additionally, allowing a guest user to use the computer system without causing others to mistake his / her identity for the primary user of the computer system can improve the usability of the computer system. In some embodiments, a primary user of the computer system optionally activates different modes of the computer system to meet his / her intended level of participation and privacy needs when participating in the computer-generated three-dimensional environment provided via the first display generating component, and the computer system provides status information associated with the various modes to alert people in the surrounding physical environment to such intentions and needs of the user, thereby reducing unintended, undesirable, and / or unnecessary interruptions and interaction avoidance by people in the surrounding physical environment. Specifically, in some of these modes, the primary user may elect to use a generic or guest representation of a portion of the body in a state displayed via the second display generating component.

[0042] As disclosed herein, a computer system communicates with a first display generating component for displaying XR content to a user in a first spatial relationship with the first display generating component and a second display generating component for displaying status information associated with the user in the first spatial relationship with the first display generating component. In some embodiments, the computer system further uses the second display generating component to display an indication of the start, continuation, and / or termination of media capture using the computer system. In some embodiments, using the second display generating component to display an alert of the start, continuation, and / or termination of media capture provides an alert to people in the surrounding environment regarding the media capture, thereby improving the safety and privacy of people in the surrounding environment.

[0043] As disclosed herein, a computer system includes at least two display generation components, wherein a first display generation component faces a user and provides a three-dimensional computer-generated experience to the user, and a second display generation component faces away from the user and provides state information related to the user (e.g., movement of the user's eyes and / or other facial features; and / or changes in the appearance of the user's face and / or eyes) and / or a computer-generated experience currently viewed by the user (e.g., metadata related to content viewed by the user and an immersion level associated with the content). The first display generation component and the second display generation component are optionally two displays enclosed in the same housing of a head-mounted display device (HMD) and facing inward toward the user wearing the HMD and outward toward the physical environment surrounding the user, respectively. In some embodiments, the computer system detects an event that satisfies criteria for changing (e.g., increasing and / or decreasing) the immersion level used to present XR content to a user viewing the XR content via the first display generation component; and in response to detecting such an event, the computer system changes the immersion level of the XR content displayed via the first display generation component and also changes the state associated with the user displayed via the second display generation component. Allowing a computer system to automatically change the immersion level based on the occurrence of certain types of events (e.g., breaking through to reveal more of the physical environment in the XR content, and / or reducing the amount of virtual content displayed in the XR environment) helps improve the safety of the user and people in the surrounding environment, and can help facilitate interaction between the user and people in the surrounding environment while the user is using the computer system.

[0044] As disclosed herein, in some embodiments, when an incoming communication request is received at a computer system that is in communication with a first display generating component and a second display generating component, the computer system displays an alert for the incoming communication request on the first display generating component or the second display generating component, depending on whether the first display generating component has a first spatial relationship with a user such that the user can view content displayed via the first display generating component, and / or whether the first display generating component or another component of the computer system is worn on the user's body. According to some embodiments, providing the alert for the incoming communication request on the first display generating component and the second display generating component provides the alert in a manner that is more easily visible to the user and allows the user to handle the incoming communication request in a more efficient manner and with fewer errors when interacting with the computer system.

[0045] As disclosed herein, when a representation of a part of a user's body is displayed via a display generation component (e.g., an external display of an HMD worn by a user, a display that obscures an external observer's direct view of a part of the user's body located behind the display, or another display that displays a representation of the part of the user's body (optionally, when the user is not physically present in the same physical environment as the display)), in response to detecting one or more changes in a set of environmental parameters associated with the physical environment in which the representation of the part of the user's body is displayed, a computer system changes a value of at least a first display parameter of the representation of the part of the user's body in accordance with the one or more changes in the set of environmental parameters. For example, a change in ambient lighting and / or a change in an observer's viewing angle of the representation of the part of the user's body causes the computer system to change (e.g., increase, decrease, and / or otherwise alter the value of) a color, brightness, translucency, and / or other display parameters of the representation of the part of the user's body, e.g., to reflect the change in environmental parameters and / or to simulate the effect of a change in the external environment on the view of the representation of the part of the user's body. However, in some embodiments, depending on the visual characteristics of the representation of the part of the user's body, for the same amount and / or type of change in an environmental parameter of the external environment in which the representation of the part of the user's body is displayed, the computer system applies different amounts of change to one or more display parameters of the representation of the part of the user's body. In response to and according to changes in environmental parameters associated with the physical environment in which the representation of the part of the user's body is displayed, the amount of change applied to the display parameters of the representation of the part of the user's body is customized based on the visual characteristics of the representation of the part of the user's body, balancing the benefits of using the appearance of the representation of the part of the user's body to provide feedback to an observer about changes in the environmental parameters of the physical environment with the need to maintain sufficient visual salience and / or realism of the representation of the part of the body for different representations of the user with different visual characteristics, thereby making the computer system more effective in communicating to an observer about the state of the computer system, the user, and / or the physical environment.

[0046] As disclosed herein, when a respective observer's viewing angle relative to an object displayed via a display generation component changes (e.g., due to movement of the display generation component and / or movement of the respective observer), if the change in viewing angle causes the respective observer to move out of a preferred viewing zone for the object, the computer system changes the values of one or more display parameters of the object that affect the visual salience of the object. In some embodiments, according to various embodiments, when multiple observers are present in the environment of the display generation component, and as the respective observer moves from one viewing zone to another viewing zone relative to the object displayed via the display generation component, the computer system changes the values of one or more display parameters of the object that affect the visual salience of the object to the respective observer, and optionally changes the values of one or more display parameters of the object displayed for another observer in the same viewing zone as the respective observer before and / or after the movement of the respective observer. Changing the value of one or more display parameters of an object based on a change in the viewing angle of the corresponding observer provides improved feedback to observers in the environment (e.g., by indicating movement of the observer in the environment and / or changes in the relative viewing angle of the observer in the environment), and provides improved security and privacy for users whose representation and / or status are displayed as objects via display generation components (e.g., by optionally changing the value of the display parameter of the user's representation relative to other status indicators associated with the user's status).

Figures 7P to 7TA computer system according to some embodiments is illustrated that displays an alert of an incoming communication request via a first display generating component or a second display generating component depending on whether the computer system or a wearable device corresponding to the computer system (e.g., an HMD, a wristband or watch, a backpack that houses components of the computer system, and / or a first display generating component) is worn by a user (e.g., worn on the user's head, wrist, or back). Figures 7U to 7AB2 A computer system according to some embodiments is illustrated that changes the values of one or more display parameters of a representation of a part of a user's body in response to detecting a change in one or more environmental parameters associated with the physical environment in which the representation of the part of the user's body is displayed.

Figure 13 is a flow chart of a method for changing values of one or more display parameters of an object other than a viewing angle of the object in response to detecting one or more movements that change a viewer's viewing angle relative to the object, according to some embodiments. Figures 7A to 7AQ The user interface in the example is used to illustrate Figures 8 to 13 in the process.

[0048] The processes described below enhance the operability of devices and make the user-device interface more efficient (e.g., by helping users provide appropriate input 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 operation, providing additional control options without cluttering the user interface with additional display controls, performing an operation without further user input when a set of conditions have been met, improving privacy and / or security, providing a richer, more detailed, and / or more realistic user experience while conserving storage space, and / or additional techniques. These techniques can also reduce power usage and extend the battery life of the device by enabling the user to use the device more quickly and efficiently. Saving battery power and, therefore, weight can improve the ergonomics of the device. These techniques can also allow the use of fewer and / or less accurate sensors, resulting in a more compact, lighter, and / or lower-cost device, and / or enable the device to be used in a variety of lighting conditions. These techniques can reduce energy usage, thereby reducing the heat generated by the device, which is particularly important for wearable devices that come into direct contact with the wearer's skin. Other advantages and benefits are also possible according to various embodiments.

[0049] In addition, in the method described herein where one or more steps depend on having met one or more conditions, it should be understood that the method can be repeated in multiple repetitions so that in the process of repetition, all conditions of the steps in the method of determining the method have been met in different repetitions of the method. For example, if the method needs to perform the first step (if the condition is met), and perform the second step (if the condition is not met), then those of ordinary skill will know that the steps stated are repeated until both the condition is met and the condition is not met (in no particular order). Therefore, the method described as having one or more steps depending on having met one or more conditions can be rewritten as a method of repeating until each condition described in the method is met. However, this does not require a system or computer-readable medium to declare that the system or computer-readable medium includes instructions for performing a contingent operation based on the satisfaction of the corresponding one or more conditions, and is therefore able to determine whether a possible situation has been met without explicitly repeating the steps of the method until all conditions of the steps in the method of determining the method have been met. Those of ordinary skill in the art will also understand that, similar to the method with a contingent step, a system or computer-readable storage medium can repeat the steps of the method as needed multiple times to ensure that all contingent steps have been performed.

[0050] In some embodiments, as Figure 1AAs shown, an XR experience is provided to a user via an operating environment 100 including a computer system 101. The computer system 101 includes a controller 110 (e.g., a processor of a portable electronic device or a remote server), a display generation component 120 (e.g., a head-mounted device (HMD), a display, a projector, a touch screen, or another type of display generation component), one or more input devices 125 (e.g., an eye tracking device 130, a hand tracking device 140, other input devices 150), one or more output devices 155 (e.g., a speaker 160, a tactile output generator 170, and other output devices 180), one or more sensors 190 (e.g., an image sensor, a light sensor, a depth sensor, a tactile sensor, an orientation sensor, a proximity sensor, a temperature sensor, a position sensor, a motion sensor, and / or a speed sensor), and optionally one or more peripheral devices 195 (e.g., a home appliance and / or a wearable device). In some embodiments, one or more of the input device 125, output device 155, sensor 190, and peripheral device 195 are integrated with the display generation component 120 (e.g., in a head-mounted device or a handheld device).

[0051] When describing an XR experience, various terms are used to distinctly refer to several related but distinct environments that a user can sense and / or with which the user can interact (e.g., using inputs detected by the computer system 101 generating the XR experience, which inputs cause the computer system generating the XR experience to generate audio, visual, and / or haptic feedback corresponding to the various inputs provided to the computer system 101). The following is a subset of these terms:

[0052] Physical Environment: The physical environment refers to the physical world that people can sense and / or interact with without the aid of electronic systems. A physical environment, such as a physical park, includes physical objects, such as physical trees, physical buildings, and physical people. People can directly sense and / or interact with the physical environment, such as through sight, touch, hearing, taste, and smell.

[0053] Extended Reality: In contrast, an extended reality (XR) environment refers to a fully or partially simulated environment that people sense and / or interact with via electronic systems. In XR, a subset of a person's physical movements, or representations thereof, is tracked, and in response, one or more properties of one or more virtual objects simulated in the XR environment are adjusted in a manner consistent with at least one law of physics. For example, an XR system can detect a person's head rotation and, in response, adjust the graphical content and sound field presented to the person in a manner similar to how such views and sounds change in a physical environment. In some cases (e.g., for accessibility reasons), adjustments to the properties of virtual objects in the XR environment can be made in response to representations of physical movement (e.g., voice commands). People can sense and / or interact with XR objects using any of their senses, including vision, hearing, touch, taste, and smell. For example, people can sense and / or interact with audio objects, which create a 3D or spatial audio environment that provides the perception of point audio sources in 3D space. As another example, audio objects can enable audio transparency, which selectively introduces ambient sounds from the physical environment with or without computer-generated audio. In some XR environments, a person may sense and / or interact only with audio objects.

[0054] Examples of XR include virtual reality and mixed reality.

[0055] Virtual Reality: A virtual reality (VR) environment is a simulated environment designed to be based entirely on computer-generated sensory input to one or more senses. A VR environment includes multiple virtual objects that a person can sense and / or interact with. For example, trees, buildings, and computer-generated images representing human avatars are examples of virtual objects. A person can sense and / or interact with virtual objects in a VR environment through the simulation of the person's presence within the computer-generated environment and / or through the simulation of a subset of the person's physical movement within the computer-generated environment.

[0056] Mixed Reality: In contrast to VR environments, which are designed to be based entirely on computer-generated sensory input, a mixed reality (MR) environment refers to a simulated environment that is designed to include sensory input from the physical environment, or representations thereof, in addition to computer-generated sensory input (e.g., virtual objects). On the virtuality continuum, a mixed reality environment is anything between, but not including, a fully physical environment at one end and a virtual reality environment at the other. In some MR environments, computer-generated sensory input can respond to changes in sensory input from the physical environment. In addition, some electronic systems used to render MR environments can track position and / or orientation relative to the physical environment to enable virtual objects to interact with real objects (i.e., physical items from the physical environment, or representations thereof). For example, the system can cause motion so that virtual trees appear stationary relative to the physical ground.

[0057] Examples of mixed reality include augmented reality and augmented virtuality.

[0058] Augmented Reality: An augmented reality (AR) environment refers to a simulated environment in which one or more virtual objects are superimposed on a physical environment or a representation of a physical environment. For example, an electronic system for presenting an AR environment may have a transparent or translucent display through which a person can directly view the physical environment. The system can be configured to present virtual objects on a transparent or translucent display so that a person uses the system to perceive the virtual objects superimposed on the physical environment. Alternatively, the system may have an opaque display and one or more imaging sensors that capture images or videos of the physical environment, which are representations of the physical environment. The system combines the images or videos with the virtual objects and presents the combination on the opaque display. A person uses the system to indirectly view the physical environment via the images or videos of the physical environment and perceives the virtual objects superimposed on the physical environment. As used herein, a video of the physical environment displayed on an opaque display is referred to as "transparent video," meaning that the system uses one or more image sensors to capture images of the physical environment and uses those images when presenting the AR environment on the opaque display. Further alternatively, the system may have a projection system that projects virtual objects into a physical environment, such as as holograms or on a physical surface, so that a person using the system perceives virtual objects superimposed on the physical environment. An augmented reality environment also refers to a simulated environment in which a representation of a physical environment is transformed by computer-generated sensory information. For example, in providing a pass-through video, the system may transform one or more sensor images to apply a selected perspective (e.g., a viewpoint) that is different from the perspective captured by the imaging sensor. For another example, the representation of the physical environment may be transformed by graphically modifying (e.g., enlarging) a portion thereof so that the modified portion may be a representative but not real version of the original captured image. For another example, the representation of the physical environment may be transformed by graphically eliminating a portion thereof or blurring a portion thereof.

[0059] Augmented Virtual: An augmented virtual (AV) environment is a simulated environment in which a virtual or computer-generated environment incorporates one or more sensory inputs from the physical environment. The sensory input can be a representation of one or more characteristics of the physical environment. For example, an AV park can have virtual trees and virtual buildings, but people's faces are realistically reproduced from images taken of physical people. In another example, a virtual object can adopt the shape or color of a physical object imaged by one or more imaging sensors. In another example, a virtual object can adopt a shadow that conforms to the position of the sun in the physical environment.

[0060] In an augmented reality, mixed reality, or virtual reality environment, a view of a three-dimensional environment is visible to a user. The view of the three-dimensional environment is typically visible to the user through a virtual viewport via one or more display generation components (e.g., a display or a pair of display modules that provide stereoscopic content to different eyes of the same user), and the virtual viewport has a viewport boundary that defines the range of the three-dimensional environment visible to the user via the one or more display generation components. In some embodiments, the area defined by the viewport boundary is smaller than the user's visual range in one or more dimensions (e.g., based on the user's visual range, the size, optical properties, or other physical properties of the one or more display generation components, and / or the position and / or orientation of the one or more display generation components relative to the user's eyes). In some embodiments, the area defined by the viewport boundary is larger than the user's visual range in one or more dimensions (e.g., based on the user's visual range, the size, optical properties, or other physical properties of the one or more display generation components, and / or the position and / or orientation of the one or more display generation components relative to the user's eyes). The viewport and viewport boundary typically move with the movement of one or more display generation components (e.g., with the user's head for a head-mounted device, or with the user's hand for a handheld device such as a tablet or smart phone). The user's viewpoint determines what is visible in the viewport. The viewpoint typically specifies a position and orientation relative to the three-dimensional environment, and as the viewpoint moves, the view of the three-dimensional environment will also move in the viewport. For head-mounted devices, the viewpoint is typically based on the position and orientation of the user's head, face, and / or eyes to provide a view of the three-dimensional environment that is perceptually accurate and provides an immersive experience when the user is using the head-mounted device. For handheld or fixed devices, the viewpoint moves as the handheld or fixed device moves and / or as the user's positioning relative to the handheld or fixed device changes (e.g., the user moves toward, away from, up, down, right, and / or left). For devices that include display generation components with virtual pass-through, portions of the physical environment that are visible (e.g., displayed and / or projected) via one or more display generation components are based on the field of view of one or more cameras in communication with the display generation components, which typically move with movement of the display generation components (e.g., with movement of the user's head for a head-mounted device, or with movement of the user's hands for a handheld device such as a tablet or smartphone) as the user's viewpoint moves with movement of the field of view of the one or more cameras (and the appearance of one or more virtual objects displayed via the one or more display generation components is updated based on the user's viewpoint (e.g., the display position and pose of the virtual objects are updated based on movement of the user's viewpoint)).For display generation components with optical transmittance, portions of the physical environment that are visible via one or more display generation components (e.g., optically visible through one or more partially or fully transparent portions of the display generation components) are based on the user's field of view through the partially or fully transparent portions of the display generation components (e.g., moves as the user's head moves for a head-mounted device, or moves as the user's hands move for a handheld device such as a tablet or smartphone) because the user's viewpoint moves as the user moves through the field of view of the partially or fully transparent portions of the display generation components (and the appearance of one or more virtual objects is updated based on the user's viewpoint).

[0061] In some embodiments, the representation of the physical environment (e.g., displayed via virtual see-through or optical see-through) may be partially or completely obscured by the virtual environment. In some embodiments, the amount of virtual environment displayed (e.g., the amount of physical environment that is not displayed) is based on the immersion level of the virtual environment (e.g., relative to the representation of the physical environment). For example, increasing the immersion level optionally causes more of the virtual environment to be displayed, replacing and / or obscuring more of the physical environment, and decreasing the immersion level optionally causes less of the virtual environment to be displayed, thereby revealing portions of the physical environment that were previously not displayed and / or obscured. In some embodiments, at a particular immersion level, one or more first background objects (e.g., in the representation of the physical environment) are visually de-emphasized (e.g., dimmed, blurred, displayed with increased transparency) more than one or more second background objects, and one or more third background objects cease to be displayed. In some embodiments, the immersion level includes an associated degree to which virtual content displayed by the computer system (e.g., a virtual environment and / or virtual content) obscures background content surrounding / behind the virtual environment (e.g., content other than the virtual environment and / or virtual content), optionally including the number of items of background content displayed and / or the displayed visual characteristics of the background content (e.g., color, contrast, and / or opacity), the angular range of the virtual content displayed via the display generation component (e.g., 60 degrees for content displayed at low immersion, 120 degrees for content displayed at medium immersion, or 180 degrees for content displayed at high immersion), and / or the proportion of the field of view displayed via the display generation component that is occupied by the virtual content (e.g., 33% of the field of view at low immersion, 66% of the field of view at medium immersion, or 100% of the field of view at high immersion). In some embodiments, the background content is included in the background on which the virtual content is displayed (e.g., background content in a representation of the physical environment). In some embodiments, the background content includes a user interface (e.g., a user interface corresponding to an application generated by a computer system), virtual objects that are not associated with or included in the virtual environment and / or virtual content (e.g., files generated by a computer system or representations of other users, etc.), and / or real objects (e.g., see-through objects representing real objects in the physical environment surrounding the user, which are visible so that they are displayed via the display generation component and / or visible via transparent or translucent components of the display generation component because the computer system does not block / impede their visibility through the display generation component). In some embodiments, at a low immersion level (e.g., a first immersion level), the background, virtual and / or real objects are displayed in an unobstructed manner. For example, a virtual environment with a low immersion level is optionally displayed simultaneously with background content, which is optionally displayed at full brightness, color and / or translucency.In some embodiments, at a higher immersion level (e.g., a second immersion level that is higher than the first immersion level), background, virtual and / or real objects are displayed in an obscured manner (e.g., dimmed, blurred, or removed from the display). For example, a corresponding virtual environment with 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 a medium immersion level is displayed simultaneously with background content that is darkened, blurred, or otherwise de-emphasized. In some embodiments, the visual characteristics of background objects vary between background objects. For example, at a particular immersion level, one or more first background objects are visually de-emphasized (e.g., dimmed, blurred, and / or displayed with increased transparency) more than one or more second background objects, and one or more third background objects cease to be displayed. In some embodiments, zero immersion or zero immersion level corresponds to a virtual environment that ceases to be displayed, and instead displays a representation of the physical environment (optionally with one or more virtual objects, such as applications, windows, or virtual three-dimensional objects), without the representation of the physical environment being obscured by the virtual environment. Adjusting the immersion level using physical input elements provides a fast and efficient method of immersion adjustment, which enhances the operability of the computer system and makes the user-device interface more efficient.

[0062] Viewpoint-locked virtual objects: When a computer system displays a virtual object at the same position and / or location in a user's viewpoint, even if the user's viewpoint shifts (e.g., changes), the virtual object is viewpoint-locked. In embodiments where the computer system is a head-mounted device, the user's viewpoint is locked to the forward direction of the user's head (e.g., when the user is looking straight ahead, the user's viewpoint is at least a portion of the user's field of view); thus, without moving the user's head, the user's viewpoint remains fixed even when the user's gaze shifts. In embodiments where the computer system has a display generation component (e.g., a display screen) that is repositionable relative to the user's head, the user's viewpoint is the augmented reality view presented to the user on the display generation component of the computer system. For example, a viewpoint-locked virtual object that is displayed in the upper left corner of the user's viewpoint when the user's viewpoint is in a first orientation (e.g., the user's head is facing north) continues to be displayed in the upper left corner of the user's viewpoint even when the user's viewpoint changes to a second orientation (e.g., the user's head is facing west). In other words, the position and / or location of the viewpoint-locked virtual object displayed in the user's viewpoint is independent of the user's position and / or orientation in the physical environment. In embodiments where the computer system is a head-mounted device, the user's viewpoint is locked to the orientation of the user's head, such that the virtual object is also referred to as a "head-locked virtual object."

[0063] Environment-locked visual objects: A virtual object is environment-locked (alternatively, "world-locked") when a computer system displays it at a location and / or position in a user's viewpoint that is based on (e.g., selected with reference to and / or anchored to) a location and / or object in a three-dimensional environment (e.g., a physical environment or a virtual environment). As the user's viewpoint moves, the location and / or objects in the environment change relative to the user's viewpoint, which causes the environment-locked virtual object to be displayed at a different location and / or position in the user's viewpoint. For example, an environment-locked virtual object locked to a tree immediately in front of the user is displayed at the center of the user's viewpoint. When the user's viewpoint shifts to the right (e.g., the user's head turns to the right) such that the tree is now to the left of center in the user's viewpoint (e.g., the tree's position in the user's viewpoint shifts), the environment-locked virtual object locked to the tree is displayed to the left of center in the user's viewpoint. In other words, the position and / or location at which an environment-locked virtual object is displayed in the user's viewpoint depends on the position and / or orientation of the object in the environment to which the virtual object is locked. In some embodiments, the computer system uses a stationary reference frame (e.g., a coordinate system anchored to fixed locations and / or objects in the physical environment) to determine the location at which an environment-locked virtual object is displayed in the user's viewpoint. An environment-locked virtual object can be locked to a stationary portion of the environment (e.g., a floor, wall, table, or other stationary object), or can be locked to a movable portion of the environment (e.g., a vehicle, animal, person, or even a representation of a part of the user's body that moves independently of the user's viewpoint, such as a hand, wrist, arm, or foot of the user) so that the virtual object moves as the viewpoint or that portion of the environment moves to maintain a fixed relationship between the virtual object and that portion of the environment.

[0064] In some embodiments, an environment-locked or viewpoint-locked virtual object exhibits an inertial following behavior that reduces or delays the movement of the environment-locked or viewpoint-locked virtual object relative to the movement of a reference point that the virtual object follows. In some embodiments, when exhibiting inertial following behavior, the computer system intentionally delays the movement of the virtual object when movement of a reference point that the virtual object is following (e.g., a portion of the environment, a viewpoint, or a point fixed relative to the viewpoint, such as a point between 5 cm and 300 cm from the viewpoint) is detected. For example, when the reference point (e.g., the portion 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 moving or slows down, at which point the virtual object begins to catch up with the reference point). In some embodiments, when the virtual object exhibits inertial following behavior, the device ignores small amounts of movement of the reference point (e.g., ignoring movements of the reference point below a threshold movement amount, such as movement from 0 degrees to 5 degrees or movement from 0 cm to 50 cm). For example, when a reference point (e.g., a portion or viewpoint of an environment to which a virtual object is locked) moves a first amount, the distance between the reference point and the virtual object increases (e.g., because the virtual object is being displayed so as to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and when the reference point (e.g., the portion or viewpoint of the environment to which the virtual object is locked) moves a second amount greater than the first amount, the distance between the reference point and the virtual object first increases (e.g., because the virtual object is being displayed so as to maintain a fixed or substantially fixed position relative to a viewpoint or portion of the environment different from the reference point to which the virtual object is locked), and then decreases when the amount of movement of the reference point increases above a threshold (e.g., a “lazy follow” threshold) because the virtual object is moved by the computer system to maintain a fixed or substantially fixed position relative to the reference point. In some embodiments, maintaining a substantially fixed position of the virtual object relative to the reference point includes displaying the virtual object within a threshold distance (e.g., 1 cm, 2 cm, 3 cm, 5 cm, 15 cm, 20 cm, 50 cm) of the reference point in one or more dimensions (e.g., up / down, left / right, and / or forward / backward relative to the position of the reference point).

[0065] Hardware: There are many different types of electronic systems that enable people to sense and / or interact with various XR environments. Examples include head-mounted systems, projection-based systems, heads-up displays (HUDs), vehicle windshields with integrated display capabilities, windows with integrated display capabilities, displays formed as lenses designed to be placed on a person's eyes (e.g., similar to contact lenses), headphones / earpieces, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablet devices, and desktop / laptop computers. A head-mounted system can have one or more speakers and an integrated opaque display. Alternatively, a head-mounted system can be configured to accept an external opaque display (e.g., a smartphone). A head-mounted system can 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. Instead of an opaque display, a head-mounted system can have a transparent or translucent display. A transparent or translucent display can have a medium through which light representing the image is directed to the person's eyes. The display may utilize digital light projection, OLED, LED, uLED, liquid crystal on silicon, laser scanning light source, or any combination of these technologies. The medium may be an optical waveguide, 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 selectively become opaque. The projection-based system may employ retinal projection technology that projects graphic images onto a person's retina. The projection system may also be configured to project virtual objects into the physical environment, for example as holograms or on a physical surface. In some embodiments, the controller 110 is configured to manage and coordinate the user's XR experience. In some embodiments, the controller 110 includes a suitable combination of software, firmware, and / or hardware. Figure 2 The controller 110 is described in more detail. In some embodiments, the controller 110 is a computing device that is located locally or remotely relative to the scene 105 (e.g., the physical environment). For example, the controller 110 is a local server located within the scene 105. As another example, the controller 110 is a remote server (e.g., a cloud server, a central server, or another type of server) located outside the scene 105. In some embodiments, the controller 110 is communicatively coupled to the display generation component 120 (e.g., an HMD, a display, a projector, a touch screen, or another type of display generation component) via one or more wired or wireless communication channels 144 (e.g., Bluetooth, IEEE802.11x, IEEE 802.16x, IEEE 802.3x, or another type of communication channel). As another example, the controller 110 includes one of the display generation component 120 (e.g., an HMD or a portable electronic device including a display and one or more processors), the input device 125, or the like.

[0066] or more input devices, one or more of output devices 155, one or more of sensors 190, and / or one or more of peripheral devices 195, is within a housing (e.g., a physical housing), or shares the same physical housing or support structure with one or more of the foregoing devices.

[0067] In some embodiments, the display generation component 120 is configured to provide an XR experience (e.g., at least the visual component of the XR experience) to the user. In some embodiments, the display generation component 120 includes a suitable combination of software, firmware, and / or hardware. Figure 3 Display generation component 120 is described in further detail. In some embodiments, the functionality of controller 110 is provided by and / or combined with display generation component 120.

[0068] According to some embodiments, display generation component 120 provides an XR experience to the user when the user is virtually and / or physically present within scene 105.

[0069] In some embodiments, the display generation component is worn on a part of the user's body (e.g., on his / her head or on his / her hand). In this way, the display generation component 120 includes one or more XR displays provided for displaying XR content. For example, in various embodiments, the display generation component 120 surrounds the user's field of view. In some embodiments, the display generation component 120 is a handheld device (such as a smart phone or tablet device) configured to present XR content, and the user holds a device with a display facing the user's field of view and a camera facing the scene 105. In some embodiments, the handheld device is optionally placed in a housing worn on the user's head. In some embodiments, the handheld device is optionally placed on a support (e.g., a tripod) in front of the user. In some embodiments, the display generation component 120 is an XR room, housing, or room configured to present XR content, wherein the user does not wear or hold the display generation component 120. Many user interfaces described with reference to one type of hardware for displaying XR content (e.g., a handheld device or a device on a tripod) can be implemented on another type of hardware for displaying XR content (e.g., an HMD or other wearable computing device). For example, a user interface that shows interactions with XR content triggered based on interactions occurring in the space in front of a handheld device or a tripod-mounted device can similarly be implemented with an HMD, where the interactions occur in the space in front of the HMD and the responses to the XR content are displayed via the HMD. Similarly, a user interface that shows interactions with XR content triggered based on movement of a handheld device or a tripod-mounted device relative to a physical environment (e.g., scene 105 or a part of a user's body (e.g., the user's eyes, head, or hands)) can similarly be implemented with an HMD, where the movement is caused by movement of the HMD relative to the physical environment (e.g., scene 105 or a part of a user's body (e.g., the user's eyes, head, or hands)).

[0070] Despite Figure 1A Relevant features of the operating environment 100 are shown in FIG, but those skilled in the art will recognize from this disclosure that various other features are not illustrated for the sake of brevity and so as not to obscure more relevant aspects of the example embodiments disclosed herein.

[0071] Figures 1A to 1PVarious examples of computer systems for performing the methods and providing audio, visual, and / or tactile feedback as part of the user interfaces described herein are illustrated. In some embodiments, the computer system includes one or more display generation components (e.g., a first display assembly 1-120a and a second display assembly 1-120b and / or a first optical module 11.1.1-104a and a second optical module 11.1.1-104b) for displaying to a user of the computer system a representation of a virtual element and / or a physical environment, optionally generated based on detected events and / or user input detected by the computer system. The user interface generated by the computer system is optionally corrected by one or more corrective lenses 11.3.2-216, which are optionally removably attached to one or more of the optical modules to make the user interface easier to view by users who would otherwise use glasses or contact lenses to correct their vision. While many of the user interfaces illustrated herein show a single view of the user interface, a user interface in an HMD is optionally displayed using two optical modules (e.g., a first display component 1-120a and a second display component 1-120b and / or a first optical module 11.1.1-104a and a second optical module 11.1.1-104b), one optical module for the user's right eye and a different optical module for the user's left eye, and presenting slightly different images to the two different eyes to create the illusion of stereoscopic depth, the single view of the user interface being typically a right eye view or a left eye view, with the depth effect being explained in text or using other diagrams or views. In some embodiments, a computer system includes one or more external displays (e.g., display component 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 to other people near the computer system, the status information being 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, which is 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 input, such as one or more sensors (e.g., sensor components 1-356 and / or Figure 1I One or more sensors in ), which can be used (optionally in combination with one or more illuminators, such as Figure 1IIn 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 sensor assembly 1-357). Figure 1I One or more sensors in ), which can be used (optionally in combination with one or more illuminators, such as Figure 1I 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., Figure 1I eye tracking and gaze tracking sensors in the , which can be used (optionally in conjunction with one or more lights, such as Figure 1O11.3.2-110) determine attention or gaze location and / or gaze movement, which can optionally be used to detect gaze-only input based on gaze movement and / or dwell. Combinations of the various sensors described above can be used to determine user facial expressions and / or hand movements for use in generating an avatar or representation of the user, such as an anthropomorphic avatar or representation for a real-time communication session, wherein the avatar has facial expressions, hand movements, and / or body movements that are 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 interaction between a user and one or more user interfaces based on direct and / or indirect input, such as air gestures or input 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), a digital crown (e.g., a pressable and twistable or rotatable first button 1-128, button 11.1.1-114, and / or dial or button 1-328), a touchpad, a touch screen, a keyboard, a mouse, and / or other input devices. One or more buttons (e.g., a first button 1-128, a button 11.1.1-114, a second button 1-132, and / or a dial or button 1-328) are optionally used to perform system operations, such as re-centering content in a three-dimensional environment visible to a user of the device, displaying a primary user interface for launching an application, starting a real-time communication session, or initiating display of a virtual three-dimensional background. A knob or digital crown (e.g., a depressible and twistable or rotatable first button 1-128, a button 11.1.1-114, and / or a dial or button 1-328) is optionally rotatable to adjust parameters of the visual content, such as the immersion level of the virtual three-dimensional environment (e.g., the extent 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 virtual content displayed via the optical modules (e.g., the first and second display components 1-120a, 1-120b, and / or the first and second optical modules 11.1.1-104a, 11.1.1-104b).

[0072] Figure 1BIllustrated are front, top, and perspective views of an example head-mounted display (HMD) device 1-100 configured to be worn by a user and to provide a virtual and altered / mixed reality (VR / AR) experience. The HMD 1-100 may 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 strap assembly 1-106 secured at either end to the electronic strap assembly 1-104. The electronic strap assembly 1-104 and the strap 1-106 may be part of a retaining assembly configured to wrap around a user's head to hold the display unit 1-102 against the user's face.

[0073] In at least one example, the strap assembly 1-106 can include a first strap 1-116 configured to wrap around the back of a user's head and a second strap 1-117 configured to extend over the top of the user's head. As shown, the second strap can extend between the first electronic strip 1-105a and the second electronic strip 1-105b of the electronic strip assembly 1-104. The strap assembly 1-104 and the strap assembly 1-106 can be part of a securing 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.

[0075] In at least one example, the first and second electronic strips 1-105a-b include plastic, metal, or other structural materials formed into the shape of substantially rigid strips 1-105a-b. In at least one example, the first band 1-116 and the second band 1-117 are formed from a resilient, flexible material including a woven textile, rubber, or the like. The first band 1-116 and the second band 1-117 can be flexible to conform to the shape of the user's head when the HMD 1-100 is worn.

[0076] In at least one example, one or more of the first and second electronic strips 1-105a-b can define an interior strip volume and include one or more electronic components disposed within the interior strip volume.

[0092] Figure 1G A perspective exploded view of a front cover assembly 3-100 of an HMD device described herein is illustrated, for example Figure 1G The front cover assembly 3-1 of the illustrated HMD 3-100 or any other HMD device shown and described herein. Figure 1GThe illustrated front cover assembly 3-100 may include a transparent or translucent cover 3-102, a shield 3-104 (or "canopy"), an adhesive layer 3-106, a display assembly 3-108 including a lenticular lens panel or array 3-110, and a structural trim 3-112. The adhesive layer 3-106 may secure the shield 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 may secure the various components of the front cover assembly 3-100 to the frame or base of the HMD device.

[0093] In at least one example, Figure 1G As shown, the transparent cover 3-102, the shield 3-104, and the display assembly 3-108 including the lenticular lens array 3-110 can be bent to accommodate the curvature of the user's face. The transparent cover 3-102 and the shield 3-104 can be bent in two or three dimensions, for example, vertically in the Z direction within and outside the ZX plane, and horizontally in the X direction within and outside the ZX plane. In at least one example, the display assembly 3-108 may include the lenticular lens array 3-110 and a display panel having pixels that are configured to project light through the shield 3-104 and the transparent cover 3-102. The display assembly 3-108 can be bent in at least one direction (e.g., horizontally) to accommodate the curvature of the user's face from one side of the face (e.g., the left side) to the other side (e.g., the right side). In at least one example, each layer or component of the display assembly 3-108 (which will be shown in subsequent figures and described in more detail, but which may include a lenticular lens array 3-110 and a display layer) may be curved similarly or concentrically in the horizontal direction to accommodate the curvature of the user's face.

[0094] In at least one example, the shield 3-104 may include a transparent or translucent material through which the display assembly 3-108 projects light. In one example, the shield 3-104 may include one or more opaque portions, such as an opaque ink-printed portion or other opaque film portion on the back of the shield 3-104. When the HMD device is worn, the back surface may be the surface of the shield 3-104 that faces the user's eyes. In at least one example, the opaque portion may be on the front surface of the shield 3-104, opposite the back surface. In at least one example, the one or more opaque portions of the shield 3-104 may include a peripheral portion that visually conceals any components surrounding the outer perimeter of the display screen of the display assembly 3-108. In this manner, the opaque portion of the shield conceals any other components of the HMD device that would otherwise be visible through the transparent or translucent cover 3-102 and / or the shield 3-104, including electronic components, structural components, etc.

[0095] In at least one example, the shield 3-104 may define one or more aperture transparent portions 3-120 through which sensors may transmit and receive signals. In one example, the portion 3-120 is an aperture through which a sensor may extend or transmit and receive signals. In one example, the portion 3-120 is a transparent portion, or a portion that is more transparent than surrounding translucent or opaque portions of the shield, through which sensors may transmit and receive signals through the shield and through the transparent cover 3-102. In one example, the sensor may include a camera, an IR sensor, a LUX sensor, or any other visual or non-visual environmental sensor of the HMD device.

The cover 6-104 may be transparent or translucent to allow light to pass through the cover 6-104, including both light detected by the sensor system 6-102 and light emitted thereby.

[0100] As described elsewhere herein, the HMD device 6-100 may include one or more controllers including processors for electrically coupling the various sensors and transmitters of the sensor system 6-102 to one or more motherboards, processing units, and other electronic devices such as display screens. Furthermore, as will be shown in greater detail below with reference to other figures, the various sensors, transmitters, and other components of the sensor system 6-102 may be coupled to Figure 1I For clarity, various structural frame members, brackets, etc. of the HMD device 6-100 are not shown. Figure 1I Components of the sensor system 6-102 are illustrated unattached and unelectrically coupled to other components.

[0101] In at least one example, the device may include one or more controllers having processors configured to execute instructions stored on a memory component electrically coupled to the processors. The instructions may include or cause the processors to execute one or more algorithms for self-correcting the angles and positions of the various cameras described herein over time as the initial position, angle, or orientation of the camera is bumped or deformed due to an accidental drop event or other event.

[0102] In at least one example, the sensor system 6-102 may include one or more scene cameras 6-106. The system 6-102 may include two scene cameras 6-102, one located on either side of the nose bridge or arch of the HMD device 6-100, such that each of the two cameras 6-106 roughly 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 generally oriented forward in the Y direction to capture images in front of the user during use of the HMD 6-100. 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 the HMD device 6-100 is in use. The scene cameras 6-106 may also be used for environment and object reconstruction.

[0103] In at least one example, the sensor system 6-102 may include a first depth sensor 6-108 pointing 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 located 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 located above a central nose bridge or on an adaptable structure above the nose of the user 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.

[0104] In at least one example, the sensor system 6-102 may include a depth projector 6-112 that faces generally forward to project electromagnetic waves (e.g., in a predetermined pattern of light dots) into or within the field of view of the user and / or scene camera 6-106, or into or within a field of view that includes and extends beyond the field of view of the user and / or scene camera 6-106. In at least one example, the depth projector may be capable of projecting electromagnetic waves of light in the form of a pattern of light dots that reflect off an object and return to the depth sensors described above, including the depth sensors 6-108, 6-110. In at least one example, the depth projector 6-112 may be used for environment and object reconstruction and hand and body tracking.

[0105] In at least one example, the sensor system 6-102 may include downward-facing cameras 6-114 whose fields of view are generally directed downward on the Z-axis relative to the HMD device 6-100. In at least one example, the downward-facing cameras 6-114 may be disposed on the left and right sides of the HMD device 6-100 as shown and used for hand and body tracking, headset tracking, and facial avatar detection and creation for displaying a user avatar on a forward-facing display screen of the HMD device 6-100 as described elsewhere herein. For example, the downward-facing cameras 6-114 may be used to capture facial expressions and movements of a user's face, including cheeks, mouth, and chin, beneath the HMD device 6-100.

[0106] In at least one example, the sensor system 6-102 may include a jaw camera 6-116. In at least one example, the jaw cameras 6-116 may be positioned on the left and right sides of the HMD device 6-100 as shown and used for hand and body tracking, headset tracking, and facial avatar detection and creation for displaying a user avatar on a front-facing display screen of the HMD device 6-100 as described elsewhere herein. For example, the jaw camera 6-116 may be used to capture facial expressions and movements of a user's face beneath the HMD device 6-100, including the user's jaw, cheeks, mouth, and chin. Used for hand and body tracking, headset tracking, and facial avatar detection and creation

[0107] In at least one example, the sensor system 6-102 may include a side camera 6-118. The side camera 6-118 may be oriented to capture left and right side views in an X-axis or direction relative to the HMD device 6-100. In at least one example, the side camera 6-118 may be used for hand and body tracking, headset tracking, and facial avatar detection and reconstruction.

[0108] In at least one example, the sensor system 6-102 may include a plurality of eye tracking and gaze tracking sensors for determining the identity, status, and gaze direction of a user's eyes during and / or prior to use. In at least one example, the eye / gaze tracking sensors may include nose-eye cameras 6-120 that are positioned on either side of the user's nose and adjacent to the user's nose when the HMD device 6-100 is worn. The eye / gaze sensors may also include bottom eye cameras 6-122 positioned below the respective user's eyes for capturing images of the eyes for use in facial avatar detection and creation, gaze tracking, and iris identification functionality.

[0109] In at least one example, the sensor system 6-102 may include an infrared illuminator 6-124 that points outward from the HMD device 6-100 to illuminate the external environment and any objects therein with IR light for IR detection using one or more IR sensors of the sensor system 6-102. In at least one example, the sensor system 6-102 may include a flicker sensor 6-126 and an ambient light sensor 6-128. In at least one example, the flicker sensor 6-126 may detect the refresh rate of overhead light to avoid display flicker. In one example, the infrared illuminator 6-124 may include a light emitting diode and may be particularly useful in low-light environments for illuminating a user's hands and other objects in low light for detection by the infrared sensors of the sensor system 6-102.

[0110] In at least one example, a plurality of sensors (including a scene camera 6-106, a downward camera 6-114, a jaw camera 6-116, a side camera 6-118, a depth projector 6-112, and depth sensors 6-108, 6-110) may be used in combination with an electrically coupled controller to combine depth data with camera data for hand tracking and for size determination to better perform hand tracking and object recognition and tracking functions of the HMD device 6-100. In at least one example, as described above and in Figure 1I The downward camera 6-114, the jaw camera 6-116, and the side camera 6-118 shown in the figure 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 only in black and white light detection to simplify image processing and gain sensitivity.

[0111] Figure 1I Any of the features, components and / or parts shown (including their arrangement and configuration) may be included alone or in any combination in the Figures 1J to 1L any other examples of the devices, features, components, and parts shown and described herein. Figures 1J to 1L Any of the features, components and / or parts shown and described, including their arrangement and configuration, may be included in the Figure 1I Examples of devices, features, components, and parts are shown.

[0112] Figure 1J A lower perspective view of an example of an HMD 6-200 including a cover or shroud 6-204 secured to a frame 6-230 is illustrated. In at least one example, the sensors 6-202 of the sensor system 6-203 may be disposed around the perimeter of the HMD 6-200 such that the sensors 6-203 are disposed outwardly around the perimeter of the display area or area 6-232 so as not to obstruct viewing of displayed light. In at least one example, the sensors may be disposed behind the shroud 6-204 and aligned with a transparent portion of the shroud, thereby allowing the sensors and projector to pass light back and forth through the shroud 6-204. In at least one example, opaque ink or other opaque material or film / layer may be disposed on the shroud 6-204 around the display area 6-232 to conceal components of the HMD 6-200 outside of the display area 6-232 rather than the transparent portion defined by the opaque portion through which the sensors and projector transmit and receive light and electromagnetic signals during operation. In at least one example, the shield 6-204 allows light to pass from the display (eg, within the display area 6-232), but does not allow light to pass radially outward from the display area around the display and the perimeter of the shield 6-204.

[0113] In some examples, the shield 6-204 includes a transparent portion 6-205 and an opaque portion 6-207, as described above and elsewhere herein. In at least one example, the opaque portion 6-204 of the shield 6-207 may define one or more transparent areas 6-209 through which the sensor 6-203 of the sensor system 6-202 may send and receive signals. In the illustrated example, the sensor 6-203 of the sensor system 6-202 sends and receives signals through the shield 6-204, or more specifically, through (or defined by) the transparent areas 6-209 of the opaque portion 6-207 of the shield 6-204, which may include a plurality of transparent regions 6-209. Figure 1I The same or similar sensors as those shown in the example of FIG, such as the depth sensors 6-108 and 6-110, the depth projector 6-112, the first and second scene cameras 6-106, the first and second downward cameras 6-114, the first and second side cameras 6-118, and the first and second infrared illuminators 6-124. These sensors are also Figure 1K and Figure 1L Other sensors, sensor types, number of sensors, and their relative positions may be included in one or more other examples of an HMD.

[0114] Figure 1J Any of the features, components and / or parts shown (including their arrangement and configuration) may be included alone or in any combination in the Figure 1I and Figures 1K to 1L any other examples of the devices, features, components, and parts shown and described herein. Figure 1I and Figures 1K to 1L Any of the features, components and / or parts shown or described (including their arrangement and configuration) may be included alone or in any combination in the Figure 1J Examples of devices, features, components, and parts are shown.

[0115] Figure 1K Illustrated is a front view of a portion of an example of an HMD device 6-300 including a display 6-334, brackets 6-336, 6-338, and a frame or housing 6-330. Figure 1K The example shown does not include a front cover or shield in order to illustrate the brackets 6-336, 6-338. For example, Figure 1J The illustrated shield 6-204 includes an opaque portion 6-207 that would visually cover / block viewing of anything external to (e.g., radially / peripherally external to) the display / display area 6-334, including the sensor 6-303 and bracket 6-338.

[0116] In at least one example, the various sensors of the sensor system 6-302 are coupled to brackets 6-336, 6-338. In at least one example, the scene cameras 6-306 include tight tolerances on angles relative to each other. For example, the tolerance on mounting angles between two scene cameras 6-306 may be 0.5 degrees or less, such as 0.3 degrees or less. To achieve and maintain such tight tolerances, in one example, the scene cameras 6-306 may be mounted to the bracket 6-338 instead of the shield. The bracket may include a cantilever on which the scene camera 6-306 and other sensors of the sensor system 6-302 may be mounted to maintain position and orientation in the event of a drop by a user that causes any deformation of the other bracket 6-226, the housing 6-330, and / or the shield.

[0117] Figure 1K Any of the features, components and / or parts shown (including their arrangement and configuration) may be included alone or in any combination in the Figures 1I to 1J and Figure 1L any other examples of the devices, features, components, and parts shown and described herein. Figures 1I to 1J and Figure 1L Any of the features, components and / or parts shown or described (including their arrangement and configuration) may be included alone or in any combination in the Figure 1K Examples of devices, features, components, and parts are shown.

[0118] Figure 1L A bottom view of an example of an HMD 6-400 including a front display / cover assembly 6-404 and a sensor system 6-402 is illustrated. The sensor system 6-402 may be similar to other sensor systems described above and elsewhere herein, including with reference to Figures 1I to 1K As described. In at least one example, the jaw camera 6-416 can face downward to capture images of the user's lower facial features. In one example, the jaw camera 6-416 can be directly coupled to the frame or housing 6-430 or one or more internal brackets that are directly coupled to the frame or housing 6-430 as shown. The frame or housing 6-430 can include one or more holes / openings 6-415 through which the jaw camera 6-416 can send and receive signals.

[0119] Figure 1L Any of the features, components and / or parts shown (including their arrangement and configuration) may be included alone or in any combination in the Figures 1I to 1K any other examples of the devices, features, components, and parts shown and described herein.

[0120] Figure 1M Illustrated is a rear perspective view of an interpupillary distance (IPD) adjustment system 11.1.1-102 comprising first and second optical modules 11.1.1-104a-b slidably engaged / coupled to respective guide rods 11.1.1-108a-b and motors 11.1.1-110a-b of left and right adjustment subsystems 11.1.1-106a-b. The IPD adjustment system 11.1.1-102 may be coupled to a bracket 11.1.1-112 and include a button 11.1.1-114 in electrical communication with the motors 11.1.1-110a-b. In at least one example, the button 11.1.1-114 may be in electrical communication with the first and second motors 11.1.1-110a-b via a processor or other circuit components to cause the first and second motors 11.1.1-110a-b to activate and respectively cause the first and second optical modules 11.1.1-104a-b to change position relative to each other.

[0121] In at least one example, the first and second optical modules 11.1.1-104a-b may include respective display screens configured to project light toward the user's eyes when the HMD 11.1.1-100 is worn. In at least one example, the user may manipulate (e.g., press and / or rotate) a button 11.1.1-114 to activate positional adjustment of the optical modules 11.1.1-104a-b to match the interpupillary distance of the user's eyes. The optical modules 11.1.1-104a-b may also include one or more cameras or other sensors / sensor systems for imaging and measuring the user's IPD so that the optical modules 11.1.1-104a-b can be adjusted to match the IPD.

[0122] In one example, a user can manipulate button 11.1.1-114 to cause automatic position adjustment of the first and second optical modules 11.1.1-104a-b. In one example, a user can manipulate button 11.1.1-114 to cause manual adjustment, causing the optical modules 11.1.1-104a-b to move further or closer (e.g., when the user rotates button 11.1.1-114 one way or another) until the user visually matches their IPD. In one example, the manual adjustment is communicated electronically via one or more circuits, and power for moving the optical modules 11.1.1-104a-b via motors 11.1.1-110a-b is provided by a power source. In one example, adjustment and movement of the optical modules 11.1.1-104a-b via manipulation button 11.1.1-114 is mechanically actuated via movement button 11.1.1-114.

[0123] Figure 1M Any of the features, components and / or parts shown (including arrangements and configurations thereof) may be included, alone or in any combination, in any other example of the apparatus, features, components and parts shown in any other drawing and described herein. Likewise, any of the features, components and / or parts shown or described with reference to any other drawing (including arrangements and configurations thereof) may be included, alone or in any combination, in any other example of the apparatus, features, components and parts shown in any other drawing and described herein. Figure 1M Examples of devices, features, components, and parts are shown.

[0124] Figure 1N Illustrated is a front perspective view of a portion of an HMD 11.1.2-100 comprising an outer structural frame 11.1.2-102 and an inner or intermediate structural frame 11.1.2-104 defining a first aperture 11.1.2-106a and a second aperture 11.1.2-106b. Figure 1N 2-106a-b may be blocked by one or more other components of the HMD 11.1.2-100 coupled to the inner frame 11.1.2-104 and / or the outer frame 11.1.2-102, as shown. In at least one example, the HMD 11.1.2-100 may include a first mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104. In at least one example, the mounting bracket 11.1.2-108 is coupled to the inner frame 11.1.2-104 between the first and second apertures 11.1.2-106a-b.

[0125] The mounting bracket 11.1.2-108 can include a middle or center portion 11.1.2-109 coupled to the inner frame 11.1.2-104. In some examples, the middle or center portion 11.1.2-109 may not be the geometric middle or center of the bracket 11.1.2-108. Instead, the middle / center portion 11.1.2-109 can be disposed between first and second cantilevered extension arms extending away from the middle portion 11.1.2-109. In at least one example, the mounting bracket 108 includes a first cantilevered arm 11.1.2-112 and a second cantilevered arm 11.1.2-114 extending away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-108 coupled to the inner frame 11.1.2-104.

[0126] like Figure 1N As shown, the outer frame 11.1.2-102 can define a curved geometry on its underside to accommodate the user's nose when the user wears the HMD 11.1.2-100. The curved geometry can be referred to as a nose bridge 11.1.2-111 and is centrally located on the underside of the HMD 11.1.2-100 as shown. In at least one example, the mounting bracket 11.1.2-108 can be connected to the inner frame 11.1.2-104 between the holes 11.1.2-106a-b so that the cantilevered arms 11.1.2-112, 11.1.2-114 extend downwardly and laterally outwardly away from the middle portion 11.1.2-109 to complement the nose bridge 11.1.2-111 geometry of the outer frame 11.1.2-102. In this way, the mounting bracket 11.1.2-108 is configured to accommodate the user's nose, as described above. The geometry of the nose bridge 11.1.2-111 adapts to the nose in that the nose bridge 11.1.2-111 provides a curvature that conforms to the shape of the user's nose, providing a comfortable fit from above, over, and around.

[0127] The first cantilever arm 11.1.2-112 can extend in a first direction away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-108, and the second cantilever arm 11.1.2-114 can extend in a second direction opposite to the first direction away from the middle portion 11.1.2-109 of the mounting bracket 11.1.2-108. The first cantilever arm 11.1.2-112 and the second cantilever arm 11.1.2-114 are referred to as "cantilevered" or "cantilever" arms because each arm 11.1.2-112, 11.1.2-114 includes a free distal end 11.1.2-116, 11.1.2-118, respectively, which are not attached to the inner frame 11.1.2-102 and the outer frame 11.1.2-104. In this way, the arms 11.1.2-112, 11.1.2-114 depend from the middle portion 11.1.2-109, which is connectable to the inner frame 11.1.2-104, while the distal ends 11.1.2-102, 11.1.2-104 are unattached.

[0128] In at least one example, the HMD 11.1.2-100 may include one or more components coupled to a mounting bracket 11.1.2-108. In one example, the components include a plurality of sensors 11.1.2-110a-f. Each of the plurality of sensors 11.1.2-110a-f may include various types of sensors, including cameras, IR sensors, and the like. In some examples, one or more of the sensors 11.1.2-110a-f may be used for object recognition in three-dimensional space, making it important to maintain the precise relative position of two or more of the plurality of sensors 11.1.2-110a-f. The cantilevered nature of the mounting bracket 11.1.2-108 may protect the sensors 11.1.2-110a-f from damage and change of position if accidentally dropped by a user. Because the sensors 11.1.2-110a-f are cantilevered on the arms 11.1.2-112, 11.1.2-114 of the mounting bracket 11.1.2-108, stresses and deformations of the inner 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 positions of the sensors 11.1.2-110a-f coupled / mounted to the mounting bracket 11.1.2-108.

[0129] Figure 1NAny of the features, components, and / or parts shown (including arrangements and configurations thereof) may be included, alone or in any combination, in any other example of a device, feature, component described herein. Likewise, any of the features, components, and / or parts shown and described herein (including arrangements and configurations thereof) may be included, alone or in any combination, in any other example of a device, feature, component described herein. Figure 1N Examples of devices, features, components, and parts are shown.

[0130] Figure 1O An example of an optical module 11.3.2-100 for use in an electronic device (such as an HMD, including the HMD devices described herein) is illustrated. As shown in one or more other examples described herein, the optical module 11.3.2-100 can be one of two optical modules within the HMD, where each optical module is aligned to project light toward an eye of a user. In this manner, a first optical module can project light toward a first eye of a user via a display screen, and a second optical module of the same device can project light toward a second eye of the user via another display screen.

[0131] In at least one example, the optical module 11.3.2-100 may include an optical frame or housing 11.3.2-102, which may also be referred to as a barrel or optical module barrel. The optical module 11.3.2-100 may also include a display 11.3.2-104 coupled to the housing 11.3.2-102, the display including one or more display screens. The display 11.3.2-104 may be coupled to the housing 11.3.2-102 such that the display 11.3.2-104 is configured to project light toward the eyes of a user when the HMD to which the display module 11.3.2-100 belongs is worn during use. In at least one example, the housing 11.3.2-102 may surround the display 11.3.2-104 and provide connection features for coupling other components of the optical module described herein.

[0132] In one example, the optical module 11.3.2-100 may include one or more cameras 11.3.2-106 coupled to the housing 11.3.2-102. The cameras 11.3.2-106 may be positioned relative to the display 11.3.2-104 and the housing 11.3.2-102 such that the cameras 11.3.2-106 are configured to capture one or more images of a user's eyes during use. In at least one example, the optical module 11.3.2-100 may also include a light strip 11.3.2-108 surrounding the display 11.3.2-104. In one example, the light strip 11.3.2-108 is disposed between the display 11.3.2-104 and the cameras 11.3.2-106. The light strip 11.3.2-108 may include a plurality of lights 11.3.2-110. The plurality of lights may include one or more light emitting diodes (LEDs) or other lights configured to project light toward the eyes of the user when the HMD is worn. The individual lights 11.3.2-110 in the light strip 11.3.2-108 may be spaced apart around the light strip 11.3.2-108 and thus evenly or unevenly spaced around the display 11.3.2-104 at various locations on the light strip 11.3.2-108 and around the display 11.3.2-104.

[0133] In at least one example, the housing 11.3.2-102 defines a viewing opening 11.3.2-101 through which a user can view the display 11.3.2-104 when wearing the HMD device. In at least one example, the LEDs are configured and arranged to emit light through the viewing opening 11.3.2-101 toward the user's eyes. In one example, the camera 11.3.2-106 is configured to capture one or more images of the user's eyes through the viewing opening 11.3.2-101.

[0134] As mentioned above, Figure 1O Each of the components and features of the illustrated optical module 11.3.2-100 may be replicated in another (eg, second) optical module provided with the HMD to interact with (eg, project light and capture images) the user's other eye.

[0136] Figure 1P A cross-sectional view of an example of an optical module 11.3.2-200 is illustrated, including a housing 11.3.2-202, a display assembly 11.3.2-204 coupled to the housing 11.3.2-202, and a lens 11.3.2-216 coupled to the housing 11.3.2-202. In at least one example, the housing 11.3.2-202 defines a first aperture or channel 11.3.2-212 and a second aperture or channel 11.3.2-214. The channels 11.3.2-212, 11.3.2-214 can be configured to slidably engage corresponding tracks or guides of an HMD device to allow the optical module 11.3.2-200 to be adjusted relative to the user's eyes to match the user's interpupillary distance (IPD). The housing 11.3.2-202 can slidably engage the guides to secure the optical module 11.3.2-200 in place within the HMD.

[0153] Memory 320 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid-state memory devices. In some embodiments, memory 320 includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid-state storage devices. Memory 320 optionally includes one or more storage devices located away from one or more processing units 302. Memory 320 includes non-transitory computer-readable storage media. In some embodiments, memory 320 or a non-transitory computer-readable storage medium of memory 320 stores the following programs, modules, and data structures, or a subset thereof, including an optional operating system 330 and an XR rendering module 340.

[0154] The operating system 330 includes processes for handling various basic system services and for performing hardware-related tasks. In some embodiments, the XR rendering module 340 is configured to present XR content to the user via one or more XR displays 312.

[0155] In some embodiments, the data acquisition unit 342 is configured to at least Figure 1A The controller 110 acquires data (e.g., presentation data, interaction data, sensor data, location data, and / or other types of data).

[0159] Although the data acquisition unit 342, the XR rendering unit 344, the XR map generation unit 346, and the data transmission unit 348 are shown as residing on a single device (e.g., Figure 1A , but it should be understood that in other embodiments, any combination of the data acquisition unit 342, the XR rendering unit 344, the XR map generation unit 346, and the data sending unit 348 may be located in a separate computing device.

[0160] also, Figure 3 It serves more as a functional description of various features that may be present in a particular embodiment, rather than as a structural schematic diagram of the embodiments described herein. As one of ordinary skill in the art will recognize, items shown separately may be combined, and some items may be separated. For example, Figure 3 Some functional modules shown separately in the figure may be implemented in a single module, and the various functions of a single functional block may be implemented by one or more functional blocks in various embodiments. The actual number of modules and the division of specific functions and how features are distributed among them will vary depending on the specific implementation and, in some embodiments, will depend in part on the specific combination of hardware, software, and / or firmware selected for a particular implementation.

[0161] Figure 4 is a schematic illustration of an example embodiment of the hand tracking device 140. In some embodiments, the hand tracking device 140 ( Figure 1A ) is controlled by the hand tracking unit 245 ( Figure 2 ) to track the position / location of one or more parts of the user's hand, and / or the movement of one or more parts of the user's hand relative to the scene 105 of Figure 1 (e.g., relative to a portion of the physical environment surrounding the user, relative to the display generation component 120, or relative to a portion of the user (e.g., the user's face, eyes, or head), and / or relative to a coordinate system (which is defined relative to the user's hand)). In some embodiments, the hand tracking device 140 is part of the display generation component 120 (e.g., embedded in or attached to the head-mounted device). In some embodiments, the hand tracking device 140 is separate from the display generation component 120 (e.g., located in a separate housing or attached to a separate physical support structure).

[0162] In some embodiments, the hand tracking device 140 includes an image sensor 404 (e.g., one or more IR cameras, 3D cameras, depth cameras, color cameras, and / or other types of image sensors) that captures three-dimensional scene information, including at least a human user's hand 406. The image sensor 404 captures images of the hand at a sufficient resolution to enable the fingers and their respective positioning to be distinguished. The image sensor 404 typically captures images of other parts of the user's body, or may also capture images of all parts of the body, and may have zoom capabilities or specialized sensors with increased magnification to capture images of the hand at a desired resolution. In some embodiments, the image sensor 404 also captures 2D color video images of the hand 406 and other elements of the scene. In some embodiments, the image sensor 404 is used in conjunction with other image sensors to capture the physical environment of the scene 105, or serves as an image sensor for capturing the physical environment of the scene 105. In some embodiments, the image sensor is positioned relative to the user or the user's environment in such a way that the field of view of the image sensor 404, or a portion thereof, is used to define an interaction space in which hand movements captured by the image sensor are treated as input to the controller 110.

[0163] In some embodiments, the image sensor 404 outputs a sequence of frames containing 3D image data (and possibly color image data) to the controller 110, which extracts high-level information from the image data. This high-level information is typically provided via an application program interface (API) to an application running on the controller, which in turn drives the display generation component 120. For example, a user can interact with the software running on the controller 110 by moving his hand 406 and changing his hand posture.

[0164] In some embodiments, the image sensor 404 projects a speckled pattern onto a scene containing the hand 406 and captures an image of the projected pattern. In some embodiments, the controller 110 calculates the 3D coordinates of points in the scene (including points on the surface of the user's hand) by triangulation based on the lateral offsets of the spots in the pattern. This approach is advantageous because it does not require the user to hold or wear any kind of beacon, sensor, or other marker. The method gives the depth coordinates of a point in the scene at a specific distance from the image sensor 404 relative to a predetermined reference plane. In the present disclosure, it is assumed that the image sensor 404 defines an orthogonal set of x-axis, y-axis, and z-axis such that the depth coordinates of a point in the scene correspond to the z component measured by the image sensor. Alternatively, the image sensor 404 (e.g., a hand tracking device) may use other 3D mapping methods, such as stereo imaging or time-of-flight measurement, based on a single or multiple cameras or other types of sensors.

[0165] In some embodiments, the hand tracking device 140 captures and processes a time series of depth maps containing the user's hand as the user moves his hand (e.g., the entire hand or one or more fingers). Software running on the image sensor 404 and / or the processor in the controller 110 processes the 3D map data to extract image patch descriptors of the hand in these depth maps. The software can match these descriptors with image patch descriptors stored in the database 408 based on a previous learning process to estimate the pose of the hand in each frame. The pose typically includes the 3D positioning of the user's hand joints and fingertips.

[0166] The software can also analyze the trajectory of the hand and / or finger over multiple frames in the sequence to identify gestures. The pose estimation function described herein can be alternated with the motion tracking function so that the image block-based pose estimation is performed only once every two (or more) frames, and tracking is used to find changes in pose that occur on the remaining frames. The pose, motion, and gesture information is provided to the application running on the controller 110 via the above-mentioned API. The program can, for example, move and modify the image presented on the display generation component 120 in response to the pose and / or gesture information, or perform other functions.

[0167] In some embodiments, gestures include air gestures. An air gesture is a gesture that is detected without the user touching an input element that is part of a device (e.g., computer system 101, one or more input devices 125, and / or hand tracking device 140) (or independent of an input element that is part of the device) and is based on detected movement of a part of the user's body (e.g., head, one or more arms, one or more hands, one or more fingers, and / or one or more legs) through air (including movement of the user's body relative to an absolute reference (e.g., the angle of the user's arm relative to the ground or the distance of the user's hand relative to the ground), movement relative to another part of the user's body (e.g., movement of the user's hand relative to the user's shoulder, movement of one of the user's hands relative to the user's other hand, and / or movement of a user's finger relative to another finger or part of the user's hand), and / or absolute movement of a part of the user's body (e.g., a tap gesture in which the hand moves a predetermined amount and / or speed in a predetermined posture, or a shake gesture including a predetermined speed or amount of rotation of a part of the user's body).

[0168] In some embodiments, according to some embodiments, the input gestures used in the various examples and embodiments described herein include air gestures for interacting with an XR environment (e.g., a virtual or mixed reality environment) performed by movement of a user's fingers relative to other fingers or parts of the user's hand. 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 through the air (including movement of the user's body relative to an absolute reference (e.g., the angle of the user's arm relative to the ground or the distance of the user's hand relative to the ground), movement relative to another part of the user's body (e.g., movement of the user's hand relative to the user's shoulder, movement of one of the user's hands relative to the user's other hand, and / or movement of the user's fingers relative to another finger or part of the user's hand), and / or absolute movement of a part of the user's body (e.g., a tap gesture in which the hand moves a predetermined amount and / or speed in a predetermined posture, or a shake gesture in which a part of the user's body is rotated at a predetermined speed or amount)).

[0169] In some embodiments where the input gesture is an in-air gesture (e.g., in the absence of physical contact with an input device that provides information to the computer system about which user interface element is the target of the user input, such as contact with a user interface element displayed on a touch screen, or contact with a mouse or trackpad to move a cursor to a user interface element), the gesture takes into account the user's attention (e.g., gaze) to determine the target of the user input (e.g., for direct input, as described below). Thus, in embodiments involving in-air gestures, for example, the input gesture is combined (e.g., simultaneously) with movement of the user's fingers and / or hand to detect attention (e.g., gaze) toward a user interface element to perform a pinch and / or tap input, as described below.

[0170] In some embodiments, an input gesture directed to a user interface object is performed directly or indirectly with reference to the user interface object. For example, user input is performed directly on the user interface object based on performing input with the user's hand at a location corresponding to the location of the user interface object in the three-dimensional environment (e.g., as determined based on the user's current viewpoint). In some embodiments, upon detecting user attention (e.g., gaze) to the user interface object, an input gesture is performed indirectly on the user interface object based on the user's hand being located not at the location corresponding to the location of the user interface object in the three-dimensional environment while the user performs the input gesture. For example, for a direct input gesture, the user can direct the user's input to the user interface object by initiating a gesture at or near a location corresponding to the displayed location of the user interface object (e.g., within 0.5 cm, 1 cm, 5 cm, or a distance between 0 and 5 cm measured from the outer edge of the option or the center portion of the option). For an indirect input gesture, the user can direct the user's input to the user interface object by focusing on the user interface object (e.g., by gazing at the user interface object), and while focusing on the option, the user initiates an input gesture (e.g., at any location detectable by the computer system) (e.g., at a location that does not correspond to the displayed location of the user interface object).

[0171] In some embodiments, according to some embodiments, input gestures (e.g., air gestures) used in various examples and embodiments described herein include pinch input and tap input for interacting with a virtual or mixed reality environment. For example, the pinch input and tap input described below are performed as air gestures.

[0172] In some embodiments, a pinch input is part of an air gesture that includes one or more of: a pinch gesture, a long pinch gesture, a pinch and drag gesture, or a double pinch gesture. For example, a pinch gesture as an air gesture includes movement of two or more fingers of a hand to contact each other, i.e., optionally followed by a break in contact with each other immediately (e.g., within 0 seconds to 1 second). A long pinch gesture as an air gesture includes movement of two or more fingers of a hand in contact with each other for at least a threshold amount of time (e.g., at least 1 second) before a break in contact with each other is detected. For example, a long pinch gesture includes the user maintaining a pinch gesture (e.g., in which the two or more fingers are in contact), and the long pinch gesture continues until a break in contact between the two or more fingers is detected. In some embodiments, a double pinch gesture as an air gesture includes two (e.g., more) pinch inputs (e.g., performed by the same hand) that are detected consecutively immediately (e.g., within a predefined time period) with respect to each other. For example, the user performs a first pinch input (e.g., a pinch input or a long pinch input), releases the first pinch input (e.g., interrupts contact between two or more fingers), and performs a second pinch input within a predefined time period (e.g., within 1 second or within 2 seconds) after releasing the first pinch input.

[0173] In some embodiments, a pinch and drag gesture as an air gesture (e.g., an air drag gesture or an air swipe gesture) includes a pinch gesture (e.g., a pinch gesture or a long pinch gesture) performed in conjunction with (e.g., following) a drag input that changes the position of the user's hand from a first position (e.g., a starting position for the drag) to a second position (e.g., an ending position for the drag). In some embodiments, the user maintains the pinch gesture while performing the drag input and releases the pinch gesture (e.g., spreads their 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., the user pinches two or more fingers to make contact with each other and moves the same hand to the second position in the air using the drag gesture). In some embodiments, a pinch input is performed by a first hand of a user, and a drag input is performed by a second hand of the user (e.g., the user's second hand moves in the air from a first position to a second position while the user continues the pinch input with the user's first hand. In some embodiments, the input gesture as an air gesture includes input performed using both hands of the user (e.g., pinch and / or tap input). For example, the input gesture includes two (e.g., or more) pinch inputs performed in conjunction with each other (e.g., concurrently or within a predefined time period). For example, a first pinch gesture (e.g., a pinch input, a long pinch input, or a pinch and drag input) is performed using the user's first hand, and a second pinch input is performed using the other hand (e.g., the second of the user's two hands) in conjunction with the pinch input performed using the first hand. In some embodiments, movement between the user's two hands (e.g., increasing and / or decreasing the distance or relative orientation between the user's two hands).

[0174] In some embodiments, a tap input performed as an air gesture (e.g., pointing to a user interface element) includes movement of a user's finger toward the user interface element, movement of the user's hand toward the user interface element (optionally, extension of the user's finger toward the user interface element), a downward motion of the user's finger (e.g., mimicking a mouse click motion or a tap on a touch screen), or other predefined movement of the user's hand. In some embodiments, a tap input performed as an air gesture is detected based on movement characteristics of the finger or hand performing the tap gesture movement of the finger or hand, which is a movement of the finger or hand away from the user's viewpoint and / or toward an object that is the target of the tap input, followed by an end of the movement. In some embodiments, the end of the movement is detected based on a change in movement characteristics of the finger or hand performing the tap gesture (e.g., an end of movement away from the user's viewpoint and / or toward an object that is the target of the tap input, a reversal of the direction of movement of the finger or hand, and / or a reversal of the acceleration direction of the movement of the finger or hand).

[0175] In some embodiments, the user's attention is determined to be directed toward a portion of the three-dimensional environment based on detection of a gaze directed toward the portion of the three-dimensional environment (optionally, no other conditions are required). In some embodiments, the user's attention is determined to be directed toward a portion of the three-dimensional environment based on detection of a gaze directed toward the portion of the three-dimensional environment using one or more additional conditions, such as requiring the gaze to be directed toward the portion of the three-dimensional environment for at least a threshold duration (e.g., a dwell duration) and / or requiring the gaze to be directed toward the portion of the three-dimensional environment when the user's viewpoint is within a distance threshold from the portion of the three-dimensional environment, so that the device determines that the user's attention is directed toward the portion of the three-dimensional environment, wherein if one of these additional conditions is not met, the device determines that the attention is not directed toward the portion of the three-dimensional environment to which the gaze is directed (e.g., until the one or more additional conditions are met).

[0176] In some embodiments, the detection of a ready state configuration of a user or a portion of a user is detected by a computer system. The detection of the ready state configuration of a hand is used by the computer system as an indication that the user may be preparing to interact with the computer system using one or more air gesture inputs performed by the hand (e.g., a pinch, a tap, a pinch and drag, a double pinch, a long pinch, or other air gestures described herein). For example, the ready state of the hand is determined based on whether the hand has a predetermined hand shape (e.g., a pre-pinch shape with the thumb and one or more fingers extended and spaced apart in preparation for a pinch or grab gesture, or a pre-tap with one or more fingers extended and the palm facing away from the user), based on whether the hand is in a predetermined position relative to the user's viewpoint (e.g., below the user's head and above the user's waist and extending at least 15 cm, 20 cm, 25 cm, 30 cm, or 50 cm from the body), and / or based on whether the hand has moved in a particular manner (e.g., toward an area in front of the user above the user's waist and below the user's head, or away from the user's body or legs). In some embodiments, the ready state is used to determine whether an interactive element of a user interface responds to attention (e.g., gaze) input.

[0177] In scenarios where input is described with reference to in-air gestures, it should be understood that similar gestures can be detected using a hardware input device attached to or held by one or more hands of a user, where the positioning of the hardware input device in space can be tracked using optical tracking, one or more accelerometers, one or more gyroscopes, one or more magnetometers, and / or one or more inertial measurement units, and the positioning and / or movement of the hardware input device is used instead of the positioning and / or movement of the one or more hands in the corresponding in-air gesture. In scenarios where input is described with reference to in-air gestures, it should be understood that similar gestures can be detected using a hardware input device attached to or held by one or more hands of a user, and user input can be detected using controls contained in the hardware input device, such as one or more touch-sensitive input elements, one or more pressure-sensitive input elements, one or more buttons, one or more knobs, one or more dials, one or more joysticks, one or more hand or finger overlays that can detect the position or change in position of parts of a hand and / or finger relative to each other, relative to the user's body, and / or relative to the user's physical environment, and / or other hardware input device controls, wherein user input performed using controls contained in the hardware input device is used in place of hand and / or finger gestures such as an air tap or air pinch in the corresponding in-air gesture. For example, a selection input described as being performed using an air tap or air pinch input can alternatively be detected using a button press, a tap on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input. As another example, movement input described as being performed using an air pinch and drag (e.g., an air drag gesture or an air swipe gesture) may alternatively be detected based on interaction with a hardware input control (such as a button press and hold, a touch on a touch-sensitive surface, a press on a pressure-sensitive surface, or other hardware input following movement of a hardware input device (e.g., along with a hand associated with the hardware input device) through space. Similarly, two-handed input comprising movement of hands relative to each other may be performed using one air gesture and one hardware input device in a hand that is not performing the air gesture, two hardware input devices held in different hands, or two air gestures performed by different hands using various combinations of air gestures and / or input detected by one or more of the aforementioned hardware input devices.

[0178] In some embodiments, the software may be downloaded to the controller 110 in electronic form, for example, over a network, or may alternatively be provided on tangible, non-transitory media such as optical, magnetic, or electronic memory media. In some embodiments, the database 408 is also stored in memory associated with the controller 110. Alternatively or in addition, some or all of the described functions of the computer may be implemented in dedicated hardware, such as a custom or semi-custom integrated circuit or a programmable digital signal processor (DSP). Although in Figure 4 , but some or all of the processing functions of the controller may be performed by a suitable microprocessor and software or by dedicated circuitry within the housing of the image sensor 404 (e.g., a hand tracking device) or other device associated with the image sensor 404. In some embodiments, at least some of these processing functions may be performed by a suitable processor integrated with the display generation component 120 (e.g., in a television receiver, handheld device, or head-mounted device) or integrated with any other suitable computerized device (such as a game console or media player). The sensing functions of the image sensor 404 may also be integrated into a computer or other computerized device to be controlled by the sensor output.

[0179] Figure 4 Also included is a schematic diagram of a depth map 410 captured by the image sensor 404 according to some embodiments. As described above, the depth map includes a matrix of pixels with corresponding depth values. Pixels 412 corresponding to the hand 406 have been segmented from the background and wrist in the figure. The brightness of each pixel within the depth map 410 is inversely proportional to its depth value (i.e., the measured z distance from the image sensor 404), where shades of gray become darker with increasing depth. The controller 110 processes these depth values in order to identify and segment components of the image (i.e., a group of adjacent pixels) that have characteristics of a human hand. These characteristics may include, for example, overall size, shape, and motion from frame to frame in the depth map sequence.

[0180] Figure 4 Also schematically illustrated is a hand skeleton 414 that the controller 110 ultimately extracts from the depth map 410 of the hand 406 according to some embodiments. Figure 4 , a hand skeleton 414 is superimposed on a hand background 416 that has been segmented from the original depth map. In some embodiments, key feature points of the hand and, optionally, on the wrist or arm connected to the hand (e.g., points corresponding to knuckles, finger tips, the center of the palm, and / or the end of the hand connected to the wrist) are identified and positioned on the hand skeleton 414. In some embodiments, the controller 110 uses the position and movement of these key feature points over multiple image frames to determine a gesture performed by the hand or the current state of the hand according to some embodiments.

[0181] Figure 5 The eye tracking device 130 ( Figure 1A ). In some embodiments, the eye tracking device 130 is composed of an eye tracking unit 243 ( Figure 2) controls to track the position and movement of the user's gaze relative to the scene 105 or relative to the XR content displayed via the display generation component 120. In some embodiments, the eye tracking device 130 is integrated with the display generation component 120. For example, in some embodiments, when the display generation component 120 is a head-mounted device (such as a headset, helmet, goggles, or glasses) or a handheld device placed in a wearable frame, the head-mounted device includes both components for generating XR content for the user to view and components for tracking the user's gaze relative to the XR content. In some embodiments, the eye tracking device 130 is separate from the display generation component 120. For example, when the display generation component is a handheld device or an XR room, the eye tracking device 130 is optionally a device separate from the handheld device or the XR room. In some embodiments, the eye tracking device 130 is a head-mounted device or a part of the head-mounted device. In some embodiments, the head-mounted eye tracking device 130 is optionally used in conjunction with a display generation component that is also head-mounted or a display generation component that is not head-mounted. In some embodiments, the eye tracking device 130 is not a head-mounted device and is optionally used in conjunction with a head-mounted display generation component. In some embodiments, the eye tracking device 130 is not a head-mounted device and is optionally part of a non-head-mounted display generation component.

[0182] In some embodiments, the display generation component 120 uses a display mechanism (e.g., a left near-eye display panel and a right near-eye display panel) to display a frame including a left image and a right image in front of the user's eyes, thereby providing the user with a 3D virtual view. For example, the head-mounted display generation component may include a left optical lens and a right optical lens (referred to herein as eye lenses) located between the display and the user's eyes. In some embodiments, the display generation component may include or be coupled to one or more external cameras that capture video of the user's environment for display. In some embodiments, the head-mounted display generation component may have a transparent or translucent display and display virtual objects on the transparent or translucent display, through which the user can directly view the physical environment. In some embodiments, the display generation component projects the virtual objects into the physical environment. The virtual objects may, for example, be projected onto a physical surface or projected as a hologram, so that the individual using the system observes the virtual objects superimposed on the physical environment. In this case, separate display panels and image frames for the left and right eyes may not be required.

[0183] like Figure 5As shown, in some embodiments, the eye tracking device 130 (e.g., a gaze tracking device) includes at least one eye tracking camera (e.g., an infrared (IR) or near infrared (NIR) camera) and an illumination source (e.g., an IR or NIR light source, such as an array or ring of LEDs) that emits light (e.g., IR or NIR light) toward the user's eyes. The eye tracking camera can be pointed at the user's eyes to receive IR or NIR light reflected directly from the eyes by the light source, or alternatively can be pointed at "hot" mirrors located between the user's eyes and the display panel, which reflect IR or NIR light from the eyes toward the eye tracking camera while allowing visible light to pass through. The eye tracking device 130 optionally captures images of the user's eyes (e.g., as a video stream captured at 60-120 frames per second (fps)), analyzes these images to generate gaze tracking information, and transmits the gaze tracking information to the controller 110. In some embodiments, both eyes of the user are tracked separately by corresponding eye tracking cameras and illumination sources. In some embodiments, only one eye of the user is tracked by corresponding eye tracking camera and illumination source.

[0184] In some embodiments, the eye tracking device 130 is calibrated using a device-specific calibration process to determine the parameters of the eye tracking device for a specific operating environment 100, such as the 3D geometry and parameters of the LED, camera, thermal mirror (if present), eye lens, and display screen. The device-specific calibration process can be performed at a factory or another facility before the AR / VR equipment is delivered to the end user. The device-specific calibration process can be an automatic calibration process or a manual calibration process. The user-specific calibration process may include an estimation of eye parameters for a specific user, such as pupil position, foveal position, optical axis, visual axis, eye distance, and / or other eye parameters. According to some embodiments, once the device-specific parameters and user-specific parameters are determined for the eye tracking device 130, a flash-assisted method can be used to process the images captured by the eye tracking camera to determine the current visual axis and the user's gaze point relative to the display.

[0185] like Figure 5As shown, the eye tracking device 130 (e.g., 130A or 130B) includes an eye lens 520 and a gaze tracking system that includes at least one eye tracking camera 540 (e.g., an infrared (IR) or near infrared (NIR) camera) positioned on the side of the user's face on which eye tracking is performed, and a light source 530 (e.g., an IR or NIR light source, such as an array or ring of NIR light emitting diodes (LEDs)) that emits light (e.g., IR or NIR light) toward the user's eye 592. The eye tracking camera 540 can be directed toward a mirror 550 (which reflects the IR or NIR light from the eye 592 while allowing visible light to pass) located between the user's eye 592 and a display 510 (e.g., a left display panel or a right display panel of a head-mounted display, or a display of a handheld device, a projector, and / or other type of display). Figure 5 ), or alternatively may be directed toward the user's eye 592 to receive reflected IR or NIR light from the eye 592 (e.g., as shown in the top portion of Figure 5 (as shown in the bottom portion of the ).

[0186] In some embodiments, the controller 110 renders AR or VR frames 562 (e.g., left and right frames for left and right display panels) and provides the frames 562 to the display 510. The controller 110 uses the gaze tracking input 542 from the eye tracking camera 540 for various purposes, such as for processing the frames 562 for display. The controller 110 optionally estimates the user's gaze point on the display 510 based on the gaze tracking input 542 obtained from the eye tracking camera 540 using a flash-assisted method or other suitable method. The gaze point estimated from the gaze tracking input 542 is optionally used to determine the direction the user is currently looking.

[0187] The following describes several possible use cases for the user's current gaze direction and is not intended to be limiting. As an example use case, the controller 110 may render virtual content differently based on the determined direction of the user's gaze. For example, the controller 110 may generate virtual content at a higher resolution in the foveal region determined based on the user's current gaze direction than in the peripheral region. As another example, the controller may position or move virtual content within the view based at least in part on the user's current gaze direction. As another example, the controller may display specific virtual content within the view based at least in part on the user's current gaze direction. As another example use case in an AR application, the controller 110 may direct an external camera used to capture the physical environment of an XR experience to focus in the determined direction. The external camera's autofocus mechanism may then focus on an object or surface in the environment on the display 510 that the user is currently looking at. As another example use case, the eye lens 520 may be a focusable lens, and the controller may use gaze tracking information to adjust the focus of the eye lens 520 so that the virtual object the user is currently looking at has the appropriate vergence to match the convergence of the user's eye 592. The controller 110 can use the gaze tracking information to guide the eye lens 520 to adjust the focus so that nearby objects that the user is looking at appear at the correct distance.

[0188] In some embodiments, the eye tracking device is part of a head-mounted device that includes a display (e.g., display 510), two eye lenses (e.g., eye lenses 520), an eye tracking camera (e.g., eye tracking camera 540), and a light source (e.g., light source 530 (e.g., IR or NIR LED)). The light source emits light (e.g., IR or NIR light) toward the user's eyes 592. In some embodiments, the light sources may be arranged in a ring or circle around each of the lenses, such as Figure 5 In some embodiments, for example, eight light sources 530 (e.g., LEDs) are arranged around each lens 520. However, more or fewer light sources 530 can be used, and other arrangements and positions of the light sources 530 can be used.

[0189] In some embodiments, the display 510 emits light in the visible range and does not emit light in the IR or NIR range, and therefore does not introduce noise into the gaze tracking system. It should be noted that the positions and angles of the eye tracking cameras 540 are given by way of example and are not intended to be limiting. In some embodiments, a single eye tracking camera 540 is located on each side of the user's face. In some embodiments, two or more NIR cameras 540 may be used on each side of the user's face. In some embodiments, a camera 540 with a wider field of view (FOV) and a camera 540 with a narrower FOV may be used on each side of the user's face. In some embodiments, a camera 540 operating at one wavelength (e.g., 850 nm) and a camera 540 operating at a different wavelength (e.g., 940 nm) may be used on each side of the user's face.

[0190] like Figure 5 The embodiments of the gaze tracking system illustrated in the can be used, for example, in computer-generated reality, virtual reality and / or mixed reality applications to provide a computer-generated reality, virtual reality, augmented reality and / or augmented virtual experience to a user.

[0191] Figure 6 A flash-assisted gaze tracking pipeline according to some embodiments is illustrated. In some embodiments, the gaze tracking pipeline is implemented by a flash-assisted gaze tracking system (e.g., Figure 1A and Figure 5 The flash-assisted gaze tracking system can maintain a tracking state. Initially, the tracking state is off or "no." When in the tracking state, the flash-assisted gaze tracking system uses previous information from previous frames when analyzing the current frame to track the pupil outline and glint in the current frame. When not in the tracking state, the flash-assisted gaze tracking system attempts to detect the pupil and glint in the current frame, and if successful, initializes the tracking state to "yes" and continues to the next frame in the tracking state.

[0192] like Figure 6 As shown, the gaze tracking camera can capture left and right images of the user's left and right eyes. The captured images are then input to the gaze tracking pipeline for processing starting at 610. As indicated by the arrow returning to element 600, the gaze tracking system can continue to capture images of the user's eyes at a rate of, for example, 60 to 120 frames per second. In some embodiments, each set of captured images can be input to the pipeline for processing. However, in some embodiments or under some conditions, not all captured frames are processed by the pipeline.

[0193] At 610, for the currently captured image, if the tracking status is yes, the method proceeds to element 640. At 610, if the tracking status is no, the image is analyzed to detect the user's pupil and glint in the image, as indicated at 620. At 630, if the pupil and glint are successfully detected, the method proceeds to element 640. Otherwise, the method returns to element 610 to process the next image of the user's eye.

[0194] At 640, if proceeding from element 610, the current frame is analyzed to track the pupil and glint based in part on previous information from the previous frame. At 640, if proceeding from element 630, the tracking state is initialized based on the pupil and glint detected in the current frame. The processing result at element 640 is checked to verify that the tracking or detection result can be trusted. For example, the result can be checked to determine whether the pupil and a sufficient number of glints were successfully tracked or detected in the current frame to perform gaze estimation. At 650, if the result is not likely to be trusted, at element 660, the tracking state is set to no, and the method returns to element 610 to process the next image of the user's eye. At 650, if the result is trustworthy, the method proceeds to element 670. At 670, the tracking state is set to yes (if not already yes), and the pupil and glint information is passed to element 680 to estimate the user's gaze point.

[0195] Figure 6 This is intended to be used as an example of an eye tracking technology that may be used for a particular implementation. As one of ordinary skill in the art will recognize, according to various embodiments, other eye tracking technologies currently existing or developed in the future may be used in place of or in combination with the flash-assisted eye tracking technology described herein in the computer system 101 for providing an XR experience to a user.

[0196] In some embodiments, the captured portion of the real-world environment 602 is used to provide an XR experience to the user, such as a mixed reality environment in which one or more virtual objects are superimposed on top of the representation of the real-world environment 602.

[0197] Thus, the description herein describes some embodiments of a three-dimensional environment (e.g., an XR environment) that includes representations of real-world objects and representations of virtual objects. For example, the three-dimensional environment optionally includes a representation of a table present in a physical environment, which is captured and displayed in the three-dimensional environment (e.g., actively displayed via a camera and display of a computer system or passively displayed via a transparent or translucent display of the computer system). As previously described, the three-dimensional environment is optionally a mixed reality system, wherein the three-dimensional environment is based on a physical environment captured by one or more sensors of the computer system and displayed via a display generation component. As a mixed reality system, the computer system is optionally capable of selectively displaying portions and / or objects of the physical environment so that the corresponding portions and / or objects of the physical environment appear as if they exist in the three-dimensional environment displayed by the computer system. Similarly, the computer system is optionally capable of displaying virtual objects in the three-dimensional environment so that it appears as if the virtual objects exist in the real world (e.g., a physical environment) by placing the virtual objects at corresponding locations in the three-dimensional environment that have corresponding locations in the real world. For example, the computer system optionally displays a vase so that the vase appears as if a real vase is placed on top of a table in the physical environment. In some embodiments, a corresponding location in the three-dimensional environment has a corresponding location in the physical environment. Thus, when a computer system is described as displaying a virtual object at a corresponding location relative to a physical object (e.g., such as at a location at or near a user's hand or at a location at or near a physical table), the computer system displays the virtual object at a particular location in the three-dimensional environment such that it appears as if the virtual object is at or near the physical object in the physical environment (e.g., the virtual object is displayed at a location in the three-dimensional environment that corresponds to the location in the physical environment where the virtual object would be displayed if it were the real object at that particular location).

[0198] In some embodiments, real-world objects present in the physical environment that are displayed in the three-dimensional environment (e.g., and / or visible via a display generation component) can interact with virtual objects that exist only in the three-dimensional environment. For example, the three-dimensional environment may include a table and a vase placed on top of the table, where the table is a view (or representation) of a physical table in the physical environment and the vase is a virtual object.

[0199] In a three-dimensional environment (e.g., a real environment, a virtual environment, or an environment comprising a mixture of real objects and virtual objects), objects are sometimes referred to as having depth or simulated depth, or objects are referred to as being visible, displayed, or placed at different depths. In this context, depth refers to a dimension other than height or width. In some embodiments, depth is defined relative to a fixed set of coordinates (e.g., where a room or object has a height, depth, and width defined relative to a fixed set of coordinates). In some embodiments, depth is defined relative to the user's position or viewpoint, in which case the depth dimension varies based on the position and angle of the user's position and / or the user's viewpoint. In some embodiments where depth is defined relative to the user's position relative to the surface of the environment (e.g., the surface of the floor or ground of the environment), objects that are farther away from the user along a line extending parallel to the surface are considered to have greater depth in the environment, and / or the depth of an object is measured along an axis extending outward from the user's position and parallel to the surface of the environment (e.g., depth is defined in a cylindrical or substantially cylindrical coordinate system where the user's position is at the center of a cylinder extending from the user's head toward the user's feet). In some embodiments where depth is defined relative to a user's viewpoint (e.g., relative to a direction of a point in space that determines which portion of an environment is visible via a head-mounted device or other display), objects that are farther away from the user's viewpoint along a line extending parallel to the user's viewpoint are considered to have greater depth in the environment, and / or the depth of objects is measured along an axis extending outward from the user's viewpoint and parallel to the user's viewpoint (e.g., depth is defined in a spherical or substantially spherical coordinate system where the origin of the viewpoint is at the center of a sphere extending outward from the user's head). In some embodiments, depth is defined relative to a user interface container (e.g., a window or application in which applications and / or system content are displayed), where the user interface container has a height and / or width, and depth is a dimension orthogonal to the height and / or width of the user interface container. In some embodiments, where depth is defined relative to a user interface container, when the container is placed in a three-dimensional environment or is initially displayed (e.g., such that the depth dimension of the container extends outward away from the user or the user's viewpoint), the height and / or width of the container is generally orthogonal or substantially orthogonal to a line extending from a user-based position (e.g., the user's viewpoint or the user's position) to the user interface container (e.g., the center of the user interface container or another feature point of the user interface container). In some embodiments, where depth is defined relative to a user interface container, the depth of an object relative to the user interface container refers to the position of the object along the depth dimension of the user interface container. In some embodiments, multiple different containers may have different depth dimensions (e.g., different depth dimensions extending away from the user or the user's viewpoint in different directions and / or from different starting points).In some embodiments, when depth is defined relative to a user interface container, the direction of the depth dimension remains constant for the user interface container as the position of the user interface container, the user, and / or the user's viewpoint changes (e.g., or when multiple different viewers are viewing the same container in a three-dimensional environment, such as during an in-person collaboration session and / or when multiple participants are in a real-time communication session with shared virtual content that includes the container). In some embodiments, for curved containers (e.g., including containers with curved surfaces or curved content areas), the depth dimension optionally extends into the surface of the curved container. In some cases, z separation (e.g., the separation between two objects in the depth dimension), z height (e.g., the distance of one object from another in the depth dimension), z position (e.g., the position of an object in the depth dimension), z depth (e.g., the position of an object in the depth dimension), or simulated z dimension (e.g., depth used as a dimension of an object, a dimension of an environment, a direction in space, and / or a direction in simulated space) is used to refer to the concept of depth as described above.

[0200] In some embodiments, the user can optionally use one or both hands to interact with virtual objects in a three-dimensional environment as if the virtual objects were real objects in the physical environment. For example, as described above, one or more sensors of the computer system optionally capture one or more of the user's hands and display representations of the user's hands in the three-dimensional environment (e.g., in a manner similar to displaying real-world objects in the three-dimensional environment described above), or in some embodiments, the user's hands can be visible via the display generation component due to the transparency / translucency of a portion of the user interface being displayed by the display generation component, or due to the projection of the user interface onto a transparent / translucent surface or onto the user's eyes or into the field of view of the user's eyes, via the ability to see the physical environment through the user interface. Thus, in some embodiments, the user's hands are displayed at corresponding locations in the three-dimensional environment and are viewed as if they were objects in the three-dimensional environment, and these objects can interact with virtual objects in the three-dimensional environment as if these virtual objects were physical objects in the physical environment. In some embodiments, the computer system can update the display of the representation of the user's hands in the three-dimensional environment in conjunction with the movement of the user's hands in the physical environment.

[0201] In some embodiments described below, the computer system is optionally capable of determining an "effective" distance between a physical object in the physical world and a virtual object in a three-dimensional environment, for example, to determine whether the physical object is directly interacting with the virtual object (e.g., whether the hand is touching, grabbing, holding, etc., or is within a threshold distance of the virtual object). For example, a hand directly interacting with a virtual object optionally includes one or more of the following: a finger of a hand pressing a virtual button, a user's hand grabbing a virtual vase, two fingers of a user's hand coming together and pinching / holding the user interface of an application, and performing any other type of interaction described herein. For example, when determining whether a user is interacting with a virtual object and / or how the user is interacting with the virtual object, the computer system optionally determines the distance between the user's hand and the virtual object. In some embodiments, the computer system determines the distance between the user's hand and the virtual object by determining the distance between the position of the hand in the three-dimensional environment and the position of the virtual object of interest in the three-dimensional environment. For example, the user's hand(s) are positioned at a specific location in the physical world, and the computer system optionally captures the hand(s) and displays the hand(s) at a specific corresponding location in the three-dimensional environment (e.g., the location at which the hand(s) would be displayed in the three-dimensional environment if the hand(s) were virtual hands rather than physical hands). The location of the hand(s) in the three-dimensional environment is optionally compared to the location of the virtual object(s) of interest in the three-dimensional environment to determine the distance between the user's hand(s) and the virtual object(s). In some embodiments, the computer system optionally determines the distance between the physical object(s) and the virtual object(s) by comparing the locations in the physical world (e.g., rather than comparing the locations in the three-dimensional environment). For example, when determining the distance between the user's hand(s) and the virtual object(s), the computer system optionally determines the corresponding location of the virtual object(s) in the physical world (e.g., the location at which the virtual object(s) would be located in the physical world if the virtual object(s) were physical objects rather than virtual objects), and then determines the distance between the corresponding physical location and the user's hand(s). In some embodiments, the same technique is optionally used to determine the distance between any physical object and any virtual object. Thus, as described herein, when determining whether a physical object is in contact with a virtual object or whether a physical object is within a threshold distance of a virtual object, the computer system optionally executes any of the techniques described above to map the position of the physical object to a three-dimensional environment and / or map the position of the virtual object to the physical environment.

[0202] In some embodiments, the same or similar techniques are used to determine where and what the user's gaze is directed to, and / or where and what the physical stylus held by the user is pointed to. For example, if the user's gaze is directed to a particular location in the physical environment, the computer system optionally determines a corresponding location in the three-dimensional environment (e.g., a virtual location of the gaze), and if a virtual object is located at the corresponding virtual location, the computer system optionally determines that the user's gaze is directed to the virtual object. Similarly, the computer system is optionally able to determine the direction in which the stylus is pointing in the physical environment based on the orientation of the physical stylus. In some embodiments, based on this determination, the computer system determines a corresponding virtual location in the three-dimensional environment that corresponds to the location in the physical environment that the stylus is pointing to, and optionally determines that the stylus is pointing to the corresponding virtual location in the three-dimensional environment.

[0203] Similarly, the embodiments described herein may refer to the position of a user (e.g., a user of a computer system) in a three-dimensional environment and / or the position of a computer system in a three-dimensional environment. In some embodiments, the user of the computer system is holding, wearing, or otherwise located at or near the computer system. Thus, in some embodiments, the position of the computer system is used as a proxy for the position of the user. In some embodiments, the position of the computer system and / or the user in the physical environment corresponds to a corresponding position in the three-dimensional environment. For example, the position of the computer system will be a position in the physical environment (and its corresponding position in the three-dimensional environment) that, if the user were standing at that position, facing the corresponding portion of the physical environment visible via the display generation component, would be visible to the user from that position in the physical environment in the same position, orientation, and / or size (e.g., in absolute terms and / or relative to each other) as the objects displayed in the three-dimensional environment by the display generation component of the computer system or visible in the three-dimensional environment via the display generation component. Similarly, if the virtual objects displayed in the three-dimensional environment are physical objects in the physical environment (e.g., physical objects placed at the same location in the physical environment as the virtual objects are located in the three-dimensional environment, and physical objects that have the same size and orientation in the physical environment as they do in the three-dimensional environment), then the position of the computer system and / or user is the position from which the user would see the virtual objects in the physical environment at the same location, orientation, and / or size (e.g., in an absolute sense and / or relative to each other and real-world objects) as the virtual objects displayed in the three-dimensional environment by the display generation components of the computer system.

[0205] User interface and associated processes

[0206] Attention is now turned to embodiments of a user interface ("UI") and associated processes that may be implemented on a computer system (such as a portable multifunction device or a head-mounted device) having one or more display generating components, one or more input devices, and (optionally) one or more cameras.

[0207] Figures 7A to 7AB2 Illustrated is a computer system according to some embodiments (e.g., Figure 1A Computer system 101 or Figure 4In some embodiments, the computer system includes and / or communicates with at least a first display generation component (e.g., as shown in display generation component 7100) and a second display generation component (e.g., as shown in second display generation component 7102), wherein the computer system displays computer-generated XR content to a user via the first display generation component (e.g., display 7100) while simultaneously displaying dynamically updated status information associated with the user and / or the computer-generated XR content and / or displaying visual alerts related to media capture and / or incoming communication requests via the second display generation component (e.g., display 7102). In addition, in some embodiments, the computer system displays a representation of a portion of the user's body via the second display generation component (e.g., display 7102 or another display) (e.g., as part of the dynamically updated status information associated with the user and / or the computer-generated XR content) and changes a value of at least a first display parameter of the representation of the portion of the user's body based on a change in a set of environmental parameters of the physical environment in which the representation of the portion of the user's body is displayed. In some embodiments, depending on the visual characteristics of the representation of the part of the user's body, the computer system changes the value of at least a first display parameter of the representation of the part of the user's body differently for the same change in the set of environmental parameters (e.g., if the visual characteristics of the representation of the part of the user's body differ by more than a threshold amount, then another display parameter of the representation is dimmed and / or otherwise changed by a different amount for the same change in ambient lighting or other environmental parameters). Figures 7A to 7AB2 To illustrate the process described below, including Figures 8 to 13 in the process.

[0208] In some embodiments, the display generation component including the first display generation component 7100 and / or the second display generation component 7102 includes a head-mounted display (HMD) (e.g., see Figures 1A to 1P In some embodiments, the head-mounted display includes: one or more inward-facing displays (e.g., the second display generation component 7100) (e.g., in Figure 7G2 、 Figure 7H2 、 Figure 7L2 、 Figure 7M2 、 Figure 7N2 、 Figure 7AA2 and Figure 7AB2 7100) that displays a representation of a portion of a three-dimensional environment corresponding to the perspective of a user wearing the HMD (e.g., first user 7202, third user 7206, and / or another user); and one or more outward-facing displays (e.g., second display generating component 7102) (e.g., in Figure 7G2 、 Figure 7H2 、 Figure 7L2 、 Figure 7M2 、 Figure 7N2 、 Figure 7AA2 and Figure 7AB2 In some embodiments, the back of the HMD 7100a corresponds to the front of the HMD 7100a. Figure 1C A rear view of the HMD 1-100, wherein the rear face of the HMD 7100a includes one or more displays (e.g., first and second display components 1-120a, 1-120b and / or first and second optical modules 11.1.1-104a, 11.1.1-104b) for displaying a user interface to a user wearing the HMD. In some embodiments, the front face of the HMD 7100a corresponds to a front perspective view of the HMD 1-100, wherein the front face of the HMD 7100a includes one or more external displays (e.g., display component 1-108).

[0209] In some embodiments, the front face of the HMD 7100a includes a portion 3-120 (e.g., as described above with reference to Figure 1G ), wherein the sensor (e.g., sensor assembly 1-356 and / or Figure 1I In some embodiments, the HMD 7100a includes one or more sensors (e.g., one or more inward-facing and / or outward-facing image sensors 314) (e.g., sensor components 1-356 and / or Figure 1I one or more sensors in the HMD 7100a), such as sensor 190a, sensor 7104, and / or sensor 7106 for detecting the state of the user wearing the HMD 7100a, including face and / or eye tracking of the user (e.g., using one or more inward-facing sensors 190a and / or 7104) (e.g., using Figure 1I Eye tracking and gaze tracking sensors in Figure 1O 2-110)) to determine attention or gaze location and / or gaze movement, which can optionally be used to detect gaze-only input based on gaze movement and / or dwell and / or tracking the user's hand, torso, or other movements (e.g., using one or more outward-facing sensors 7106). In some embodiments, the HMD 7100a includes one or more input devices, such as one or more buttons, a touchpad, a touch screen, a scroll wheel, a rotatable and depressible digital crown, or other input device, optionally located on the housing of the HMD 7100a. In some embodiments, the input element is a mechanical input element, and in some embodiments, the input element is a solid-state input element that responds to a press input based on detecting pressure or intensity. For example, in Figure 7G2 、 Figure 7H2 、 Figure 7L2 、 Figure 7M2 、 Figure 7N2 、 Figure 7AA2 and Figure 7AB2 , the HMD 7100a includes one or more of a button 7302 (e.g., and / or buttons 11.1.1-114, a second button 1-132, and / or a dial or button 1-328) and a digital crown (e.g., a first button 1-128 and / or buttons 11.1.1-114, and / or a dial or button 1-328) for providing input to the HMD 7100a. It should be understood that additional and / or alternative input devices may be included in the HMD 7100a.

[0210] Although an HMD typically includes multiple displays, including a display for the right eye and a separate display for the left eye that displays slightly different images to obtain a user interface with stereoscopic depth, in the figure, a single image corresponding to a monocular image is displayed and depth information is indicated with other annotations or descriptions of the figure.

[0211] exist 7A to 7F In some embodiments, two different users (e.g., 7A to 7C The first user 7202 and Figures 7D to 7F The third user 7206 in FIG. 7 is respectively present in front of the display side of the first display generating component 7100 through which the XR content is displayed, and the computer system determines whether the user satisfies the first criterion related to the identity of the user (for example, in FIG. 7A to 7C , the first user 7202 meets the first criterion; and Figures 7D to 7F , the third user 7206 does not meet the first criterion) to display respective representations of a portion of the body of the two users at different fidelity levels (e.g., 7A to 7B The representation 7006 of the first user 7202 has a Figures 7D to 7E The representation 7208 of the third user 7206 in the has a higher fidelity level). 7A to 7B In some embodiments, the computer system updates the appearance of the representation 7006 of the portion of the body of the first user 7202 based on the change in the appearance of the first user 7202; Figures 7D to 7E , the computer system updates the appearance of the representation 7208 of the part of the body of the third user 7206 based on the change in the appearance of the third user 7206, wherein the computer system continues to maintain the difference in fidelity levels between the representation 7006 of the first user 7202 and the representation 7208 of the third user 7206 because the first user 7202 meets the first criterion and the third user 7206 does not meet the first criterion. In some embodiments, as Figure 7C and Figure 7FAs shown, when the immersion level reaches a level higher than a threshold immersion level (e.g., reaches a fully immersed state or another highly immersed state), the computer system abandons displaying representations of parts of the user's body (e.g., representation 7006 of the first user 7202 and representation 7208 of the third user 7206) via the first display generating component, regardless of whether the user meets the first criterion (e.g., the first user 7202 meets the first criterion, and the third user 7206 does not meet the first criterion), and only displays status information of the CGR content (e.g., the status information of the CGR content, respectively). Figure 7C and Figure 7F In some embodiments, when the immersion level reaches above a threshold immersion level (e.g., reaches a fully immersed state or another highly immersed state), the computer system displays the same state information (e.g., optionally including a common representation for both the first user 7202 and the third user 7206 and the same overlay 7008 for the state of the XR content) via the second display generation component 7102, regardless of whether the users meet the first criteria (e.g., the first user 7202 meets the first criteria, and the third user 7206 does not meet the first criteria). According to some embodiments, with respect to Figure 8 The method 8000 in provides more details about the characteristics of different immersion levels for presenting XR content via the first display generation component 7100 and their impact on the display of the XR content via the first display generation component and the display of state information associated with the first user via the second display generation component 7102. 7A to 7F Further details of the illustrated computer systems and interactions.

[0212] like Figure 7A As shown in the left portion of FIG, a first display generation component (e.g., as illustrated by first display generation component 7100) is present at location A 7000-a and displays XR content (e.g., a three-dimensional movie, a virtual reality game, a video, and / or a three-dimensional environment including user interface objects and optionally a representation of a physical environment). A first user 7202 is also present at location A 7000-a.

[0213] like Figure 7A As shown in the right portion of , the second display generation component (e.g., as illustrated by the second display generation component 7102) exists at position B 7000-b and displays state information associated with the first user (e.g., including state information corresponding to the first user 7202 and / or corresponding to the XR content presented via the first display generation component 7100). Figure 7AIn the illustrated example scenario, second user 7204 is optionally present at location B 7000-b. According to some embodiments, for the purposes of discussion herein, second user 7204 is not a user of the computer system and does not actively provide user input to the computer system using an input device of the computer system to interact with the computer system (even though, optionally, the computer system detects the first user's actions and appearance as contextual information gathered from the physical environment in some operations of the computer system).

[0214] like Figure 7A As shown, the spatial relationship between the first display generation component 7100 and the first user 7202 is such that the first user 7202 is in a position to view the XR content 7002 presented via the first display generation component 7100. For example, the first user 7202 faces the display side of the first display generation component 7100. In some embodiments, the first display generation component 7100 is an internal display of the HMD (e.g., referring to FIG. Figures 1A to 1P The HMD device 1-100, wherein the first display generating component 7100 corresponds to one or more inward-facing displays (e.g., Figure 7G2 、 Figure 7H2 、 Figure 7L2 、 Figure 7M2 、 Figure 7N2 、 Figure 7AA2 and Figure 7AB27000-a) and the spatial relationship represented by the coexistence of the first display generation component 7100 and the first user 7202 at the same location A 7000-a corresponds to the first user wearing the HMD on their head and / or holding the HMD with the internal display of the HMD facing the eyes of the first user. In some embodiments, when the first user 7202 faces a portion of the physical environment illuminated by the projection system of the first display generation component 7100, the first user 7202 is in a position to view XR content presented via the first display generation component 7100. For example, virtual content is projected onto the portion of the physical environment, and the first user 7202 sees the virtual content and the portion of the physical environment through a camera view of the portion of the physical environment or through a transparent portion of the first display generation component 7100 when the first user 7202 faces the display side of the first display generation component 7100. In some embodiments, when the first user faces the display side of the first display generation component 7100, the first display generation component 7100 emits light that forms an image on the first user's retina. For example, virtual content is displayed by an LCD or LED display as overlaying or replacing a portion of the view of the physical environment displayed by the LCD or LED display, and a first user facing the display side of the LCD or LED display can see the virtual content together with the view of the portion of the physical environment. In some embodiments, the first display generation component displays a camera view of the physical environment in front of the first user or includes a transparent or semi-transparent portion through which the first user can see a portion of the physical environment in front of the first user. In some embodiments, the portion of the physical environment visible to the first user 7202 through the first display generation component 7100 is the portion of the physical environment corresponding to the display side of the second display generation component 7102 (e.g., including the display side of the second display generation component 7102 and optionally, position B 7000-b of the second user 7204). In some embodiments, the display side of the second display generating component 7102 is the side of the second display generating component 7102 that faces away from the first user 7202 when the first user 7202 is in a position to view the content displayed by the first display generating component 7100 (for example, when the first user 7202 faces the display side of the first display generating component 7100), and this side emits light that forms an image viewable by others facing a preset part of the first user (for example, the second user 7204 or others facing the face or eyes of the first user in the physical environment). In some embodiments, the first user 7202 and the first display generating component 7100 coexist in Figure 7APosition A 7000-a in exemplifies that a first user 7202 wears (e.g., on the user's head, above the user's eyes, on the user's wrist, on the user's back, and / or other part of the user) a wearable device (e.g., a watch, wristband, backpack, and / or other wearable device) that includes a first display generating component, a second display generating component, a computer system, and / or components of one or more of the foregoing.

[0215] like Figure 7A As shown, the spatial relationship between the second display generating component 7102 and the second user 7204 is such that the second user 7204 is in a position to view the status information presented via the second display generating component 7102. For example, the second user 7204 is in front of and / or facing the display side of the second display generating component 7102. In some embodiments, the second display generating component 7102 is an HMD (e.g., referring to FIG. Figures 1A to 1P The HMD device 1-100, wherein the second display generation component 7102 corresponds to one or more outward-facing displays (e.g., Figure 7G2 、 Figure 7H2 、 Figure 7L2 、 Figure 7M2 、 Figure 7N2 、 Figure 7AA2 and Figure 7AB2 710a)) and an external display (e.g., labeled “front” of the HMD 7100a in FIG. 1 ), the HMD also including an internal display (e.g., represented by a first display generating component 7100 corresponding to one or more inward-facing displays (e.g., in FIG. 1 ) that presents XR content to the first user 7202. Figure 7G2 、 Figure 7H2 、 Figure 7L2 、 Figure 7M2 、 Figure 7N2 、 Figure 7AA2 and Figure 7AB2In some embodiments, the first display generating component 7100 displays a camera view of the physical environment in front of the first user 7202 or includes a transparent or semi-transparent see-through portion through which the first user 7202 can see a portion of the physical environment in front of the first user 7202, and the portion of the physical environment included in the camera view or see-through portion is also the portion of the physical environment in front of the display side of the second display generating component 7102. In some embodiments, the second display generating component 7102 is positioned back-to-back with the first display generating component 7100 such that the portion of the physical environment in front of the display side of the second display generating component 7102 (e.g., location B 7000-b including the display side of the second display generating component 7102 and optionally the second user 7204) is also in front of the first user 7202 and within the field of view of the first user when the first display generating component and the second display generating component do not obscure the face of the first user. In some embodiments, unlike the case where the first user 7202 and the first display generating component 7100 coexist at location A 7000-a, the second user 7204 and the second display generating component 7102 coexist at location B 7000-b. Figure 7A Position B 7000-b in does not mean that the second user 7204 is wearing (e.g., on the user's head, above the user's eyes, on the user's wrist, on the user's back, and / or other part of the user) a wearable device (e.g., a wearable device, watch, wristband, backpack, and / or other wearable device worn by the first user 7202) that includes the first display generating component, the second display generating component, the computer system, and / or components of any of the foregoing. In fact, in 7A to 7T In at least some of the illustrated scenarios, according to some embodiments, the second user 7204 is not required to be present at location B 7000 - b for changes to occur on the first display generating component 7100 and the second display generating component 7102 .

[0216] As mentioned above and will be repeated here, although Figure 7A (as well as 7B to 7T ) shows the first display generating component 7100 and the second display generating component 7102 as being located in two separate and non-intersecting portions of the physical environment, but it should be understood that the first display generating component and the second display generating component are optionally housed in the same housing (e.g., a single HMD (e.g., see FIG. Figures 1A to 1PThe HMD device 1-100 of claim 1, wherein the first display generating component 7100 corresponds to one or more inward-facing displays and the second display generating component 7102 corresponds to one or more outward-facing displays enclosed in the same housing of the HMD device 1-100, a housing of a handheld device, or a housing of another wearable device, or attached to the same support structure (e.g., attached back-to-back with each other or attached to opposite sides of a single wall or surface) and facing different (e.g., generally opposite or angled) directions. Thus, position A 7000-a represents a first portion of the physical environment from which content presented via the first display generating component 7100 is visible to a first user (e.g., the first user 7202) facing the display side of the first display generating component 7100 and from which content (e.g., status information) presented via the second display generating component 7102 is not visible to the first user (e.g., the first user 7202 when the first user 7202 is facing the display side of the first display generating component 7100); and position B 7000-b represents a second part of the same physical environment, from which another user (e.g., the second user 7204, or the first user 7202 when the first user 7202 moves (or rotates the display generating component) to face the display side of the second display generating component 7102) cannot see the content presented via the first display generating component 7100, and from which the other user (e.g., the second user 7204, or the first user when the first user 7202 moves (or rotates the display generating component) to face the display side of the second display generating component 7102) can see the content (e.g., status information and / or visual alerts) presented via the second display generating component 7102. In the disclosure presented herein, the first display generating component 7100 and the second display generating component 7102 are controlled by the same computer system (e.g., an HMD, a portable electronic device housed separately from the display generating component, a portable electronic device having two displays facing different directions, and / or a remote server computer), and unless otherwise specified, a user of the computer system generally refers to a person who can control at least the first display generating component 7100 to place the first display generating component or himself / herself in a position that enables him / her to see the XR content shown via the first display generating component 7100.Based on the disclosure presented herein, it should be apparent that, according to some embodiments, the first display generation component 7100 and the second display generation component 7200 are distinct from two separate display devices (and computer systems) used by two different users in a communication session (e.g., a video call, voice call, coexistence session, and / or other shared three-dimensional experience), and that the example scenarios presented herein address different challenges and provide different solutions due to the nature of the display generation components and their functionality related to providing an XR experience to users.

[0217] like Figure 7A As shown, the computer system controlling the first display generation component 7100 and the second display generation component 7102 and the first image sensor (eg, camera 7104 and / or Figure 1I sensor components 1-356 in the embodiment of the present invention) and a second image sensor (e.g., camera 7106, eye tracking sensor, gaze tracking sensor and / or Figures 1A to 1PThe first image sensor is configured to capture an image of a portion of the physical environment (e.g., location A 7000-a) that includes at least a portion of the first user's body facing the display side of the first display generating component 7100 (e.g., the first user's face, upper body part, eye region, and / or eyes) and excludes the second user 7204 (or excludes any other users if the first display generating component 7100 is an internal display of an HMD worn by the first user 7202). The second image sensor (e.g., image sensor 7106) is configured to capture an image of a portion of the physical environment (e.g., location B 7000-b) that excludes a portion of the first user 7202 (e.g., the first user's face, upper body part, eye region, and / or eyes), but optionally includes at least a portion of the second user (e.g., a portion of the second user 7204 that is in the field of view of the first user 7202 provided by the first display generating component 7100). As previously discussed, in some embodiments, the portion of the physical environment captured by the second image sensor 7106 includes the portion of the physical environment that is in the first user's field of view when the first user's eyes are not physically obstructed by the presence of the second display generation component 7102 (and optionally the presence of the first display generation component 7100). Similarly, in some embodiments, the portion of the physical environment captured by the first image sensor 7104 includes the portion of the first user 7202 (e.g., the first user's face, upper part of the user, eye region, and / or eyes) that is physically obstructed by the presence of the first display generation component 7100 (and optionally the presence of the second display generation component 7102). In some embodiments, the computer system also communicates with the first image sensor, the second image sensor, and / or other image sensors to receive images of the hands and wrists of the first user 7202 for identifying gesture input provided by the first user 7202 and / or for detecting the presence, movement, or gestures of the second user 7204. In some embodiments, the first image sensor 7104 is also used to capture gaze input provided by the first user 7202. In some embodiments, the first image sensor and the second image sensor are optionally used as image sensors for capturing gesture input of the first user 7202 and / or the second user 7204.

[0218] In some embodiments, the computer system optionally controls one or more audio output devices (e.g., Figures 1A to 1PThe computer system may further include an electronic component 1-112 or other audio output device in the computer system, the one or more audio output devices providing audio output (e.g., sounds of XR content and / or audio alerts and feedback) to a first user 7202 located at location A 7000-a and optionally providing audio output (e.g., status indication sounds or alerts, sounds of XR content, and / or other types of audio output) to a second user 7204 located at location B 7000-b. In some embodiments, the computer system optionally partially or completely blocks location A and the first user 7202 from sounds propagating from location B (e.g., via one or more active or passive noise suppression or cancellation components), and optionally partially or completely blocks location B and the second user 7204 from sounds propagating from location A. In some embodiments, the amount of active sound blocking and / or sound transmission is determined by the computer system based on the current immersion level associated with the XR content shown via the first display generating component 7100 (e.g., no sound blocking when in transmission mode, partial sound blocking when in mixed reality mode, and / or complete sound blocking when in virtual reality mode) and, optionally, based on whether another user is present at location B (e.g., no sound blocking when no person is at location B and / or sound blocking when a person is at location B or the noise level exceeds a threshold level).

[0219] In some embodiments, as Figure 7A As shown, when the first user 7202 is in a position to view the XR content 7002 (for example, the first user 7202 is placed in position A with the first display generating component 7100 and at least partially faces the display side of the first display generating component, and / or the first user 7202 wears the HMD on his head or holds or carries the HMD or a device housing the first display generating component, the second display generating component, the computer system, or a component of any of the above, with the display area facing his eyes), the computer system displays the XR content 7002 via the first display generating component 7100 (for example, an internal display of the HMD) (for example, on the Figure 7A 7002-a). Figure 7AAt the moment illustrated, the computer system is displaying XR content 7002 (e.g., a three-dimensional environment, Movie X, a three-dimensional movie, a two-dimensional movie, and / or other interactive or non-interactive computer-generated experience). The XR content 7002 is displayed in a mixed reality mode, wherein the XR content 7002 includes virtual content that is simultaneously visible through the first display generation component 7100 with a representation of the physical environment (e.g., a representation of Location B (e.g., a portion of the physical environment that is in front of the first user and obscured by the presence of the first display generation component)). In some embodiments, the mixed reality mode corresponds to an intermediate immersion level associated with the XR content presented via the first display generation component 7100. In some embodiments, the intermediate immersion level also corresponds to partial blocking or partial transmission of sound propagating from the physical environment (e.g., Location B (e.g., a portion of the physical environment surrounding the first user 7202)). In this example, the representation of the physical environment includes a representation 7010 (e.g., in front of the back side of the first display generating component 7100) of a second user 7204 located in position B 7000-b, in front of the second display generating component 7102 (e.g., also in front of the back side of the first display generating component 7100). Figure 7AIn some embodiments, the representation of the physical environment includes a camera view of a portion of the physical environment that would be within the first user's field of view when the first user's eyes are not obscured by the presence of the first display generating component and the second display generating component (e.g., when the first user 7202 is not wearing an HMD or holding or carrying the HMD in front of their eyes). In mixed reality mode, XR content 7002 (e.g., a three-dimensional environment, Movie X, a three-dimensional augmented reality environment, a user interface, a virtual object, and / or other XR content) is displayed to cover or replace at least a portion, but not all, of the representation of the physical environment. In some embodiments, the first display generating component 7100 includes a transparent portion through which the first user 7202 can see a portion of the physical environment. In some embodiments, in mixed reality mode, XR content 7002 (e.g., a three-dimensional environment, CinemaX, a three-dimensional augmented reality environment, a user interface, a virtual object, and / or other XR content) is projected onto a physical surface or empty space in the physical environment and is visible along with the physical environment through a transparent portion and viewable through a transparent portion of the first display generation component 7100 or through a camera view of the physical environment provided by the first display generation component 7100. In some embodiments, the XR content 7002 is displayed to cover a portion of the display and obstruct the view of at least a portion, but not all, of the physical environment visible through the transparent or semi-transparent portion of the first display generation component 7100. In some embodiments, the first display generation component 7100 does not provide a view of the physical environment, but rather provides a fully virtual environment (e.g., without a camera view or transparent pass-through portion) augmented with a real-time visual representation (e.g., a stylized representation or segmented camera image) of the physical environment as currently captured by one or more sensors (e.g., a camera, a motion sensor, other gesture sensors, and / or other types of sensors). In some embodiments, the real-time visual representation of the physical environment includes a representation based on an image captured with some computational and / or signal processing delay (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users). In a mixed reality mode (e.g., augmented reality based on a camera view or a transparent display, or augmented virtuality based on a virtualized representation of the physical environment), the first user 7202 is not fully immersed in the computer-generated environment and is still receiving sensory information (e.g., visual and audio) that directly corresponds to the physical environment surrounding the first user and the first display generating component. In some embodiments, the increased level of immersion corresponds to an increased amount of visual and / or sensory information from the physical environment in the XR environment (e.g., increased amount, increased spatial extent, and / or increased salience) and / or a reduced amount of information from virtual content in the XR environment (e.g., increased amount, increased spatial extent, and / or increased salience).In some embodiments, the user's immersion level (e.g., a low immersion level, a medium immersion level, and / or a high immersion level) is determined based on the pixel occupancy of the representation of the virtual content relative to the real-world content (e.g., the percentage of the user's viewport occupied by the virtual content as compared to the transparent content). In some embodiments, the determination of the current immersion level used to provide a representation of the three-dimensional environment via the first display generation component is based on a comparison between the corresponding amount of virtual content currently presented via the first display generation component and the corresponding amount of transparent content (e.g., based on a comparison of pixel occupancy (e.g., the absolute number of pixels used to represent virtual content and transparent content, respectively, and / or the total display area occupied by virtual content and transparent content, respectively), a ratio between pixels representing virtual content and pixels representing transparent content, and / or other indications of the relative visual prominence of the virtual content and the transparent content). Other definitions of immersion level are possible according to various embodiments.

[0220] like Figure 7A As shown, while the computer system displays XR content 7002-a (e.g., a three-dimensional environment, movie X, a three-dimensional augmented reality environment, a user interface, a virtual object, and other XR content) in a mixed reality mode via the first display generation component 7100, the computer system displays state information related to the first user and the XR content via the second display generation component 7102. Figure 7A As shown in the right portion of FIG, the second display generation component 7102 displays one or more graphical elements representing the state of the XR content 7002 displayed via the first display generation component 7100, and a representation 7006 of at least a portion of the first user 7202 in front of the display side of the first display generation component 7100 (e.g., Figure 7A In this example, the one or more graphical elements representing the state of the XR content displayed via the first display generating component 7100 optionally include an identifier of the XR content 7002 (e.g., the name of movie X), a progress bar 7004 showing the current progress of the XR content (e.g., Figure 7A 7004-a) and a visual representation of the XR content (e.g., Figure 7A In some embodiments, the overlay 7008 representing the state of the XR content is generated by blurring the XR content (e.g., by blurring, distorting, darkening, desaturating, and / or increasing transparency) and conveys only the changing feel and color or hue of the XR content 7002. Figure 7A, the representation 7006 of the portion of the body of the first user 7202 optionally includes a camera view of the first user's face or a graphical representation generated based on the camera view of the first user's face. In some embodiments, the representation 7006 of the portion of the body of the first user 7202 optionally includes a camera view of a portion of the body of the first user 7202, such as the face, upper portion of the face, eye region, or eyes of the first user 7202, or a graphical representation generated based on a camera view and / or stored images of the portion of the body of the first user 7202. In some embodiments, the representation 7006 of the portion of the body of the first user 7202 is based on an image and / or model obtained through a registration process undergone by the first user 7202, wherein a high-fidelity image and / or model of the first user forms the basis of the representation 7006 of the first user 7202. In some embodiments, the representation 7006 may appear different from a real-time image of the first user 7202 (e.g., a real-time image that optionally includes an image of the first user that has been captured with some computational and / or signal processing delay (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users)) (e.g., the skin color and / or other display characteristics of the representation 7202 are different from 7A to 7B skin color and / or other display characteristics of the first user 7202 in the example), as the first user's appearance may have changed since completing the registration process.

[0221] In some embodiments, animated movement and changes in appearance of body features in the representation 7006 of the portion of the body of the first user 7202 are generated to correspond to real-time movement and changes in appearance of body features in the portion of the body of the first user 7202 (e.g., the real-time movement and changes in appearance optionally include movement and changes in appearance with some computational and / or signal processing latency (e.g., latency of less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users). In some embodiments, the representation 7006 of the portion of the first user 7202 is displayed in a display layer that is different from the display layer of one or more graphical elements representing the state of the XR content (e.g., the overlay 7008 and the progress bar 7004). In some embodiments, content displayed on different display layers can be distinguished when an observer moves relative to the second display generating component and sees different amounts of parallax effect for the content shown on the different display layers. In some embodiments, the simultaneous display by the second display generation component 7102 of a representation of the state of the XR content (e.g., the overlay 7008 and the progress bar 7004) and a representation 7006 of a portion of the body of the first user 7202 provides an indication that the XR content is being displayed in a mixed reality mode via the first display generation component 7100 and that the first user 7202 has a view of the physical environment and the XR content 7002. By displaying a visual representation of the first user's physical features (e.g., face and / or eyes) and a representation of the state of the XR content being viewed by the first user 7202 on the second display generation component 7102 when the first user's physical features (e.g., face and / or eyes) are occluded by the presence of the first display generation component 7100 (and optionally the presence of the second display generation component 7102) (e.g., by the presence of an HMD including an internal display and an external display), other people in the physical environment surrounding the first user 7202 are provided with more information for initiating or refraining from interacting with the first user 7202 or for causing him / herself to behave in an appropriate manner in the presence of the first user 7202.

[0222] Figure 7B follow Figure 7A, and illustrates that at a later time, the XR content 7002 has further progressed on the first display generating component 7100, and the appearance of the portion of the body of the first user 7202 has changed. For example, the change in the appearance of the portion of the body of the first user 7202 is due to movement of at least a portion of the portion of the body of the first user 7202 (e.g., eyes, nose, eyebrows, mouth, or other physical features of the portion of the body of the first user) relative to the first display generating component 7100 (e.g., movement including sideways and / or up and down movement of the first user's eyeballs, squinting, opening, closing, and / or blinking of the user's eyes, movement of eyebrows (e.g., frowning, raising, and / or raising eyebrows), movement of the nose (e.g., twisting, pursing, and / or opening), movement and / or change of cheeks (e.g., puffing or twitching), and / or movement including the user's face or head relative to the display side of the first display generating component (e.g., moving away from or toward the first display generating component 7100) at position A). 7000-a (e.g., while the first user 7202 is still wearing the HMD and / or facing the internal display of the HMD). In some embodiments, the change in the appearance of the portion of the body of the first user 7202 is due to a change in the color, shape, and / or other visual characteristics of physical features in the portion of the body (e.g., sweating, whitening, reddening, and / or blueing of the skin, dilated pupils, tearing of the eyes, drooping of the jaw, and / or relaxation of facial muscles). At this time, the XR content 7002 is still displayed in mixed reality mode and includes a representation 7010 of the second user 7204 (e.g., in Figure 7B 7010-b) in the figure (e.g., location B, optionally including the second user 7202) is maintained simultaneously displayed between the XR content 7002 via the first display generation component 7100. In some embodiments, changes in the appearance of the physical environment (e.g., visual changes in the body features of the second user 7204 and the movement of the second user 7204 relative to the first display generation component 7100, the second display generation component 7102 and / or the first user 7202) are also reflected by the representation of the physical environment shown by the first display generation component 7100. In some embodiments, the computer system updates the representation 7006 displayed via the second display generation component 7102 (e.g., in the figure) based on changes in the appearance of parts of the body that include the movement of the first user 7202 relative to the first display generation component (e.g., changes in the appearance and movement of the eyes, eye regions and / or face of the first user). Figure 7BFor example, when the first user 7202 or a portion of the first user's body (e.g., the first user's face or eyes) moves in a direction toward a first edge of the first display generating component 7100 (e.g., the left edge of the display side of the first display generating component, or the top edge of the display side of the first display generating component when viewed from the display side of the first display generating component 7100), the representation 7006 of the portion of the first user's body shown on the display side of the second display generating component also moves toward a corresponding second edge of the second display generating component 7102 (e.g., the right edge of the display side of the second display generating component (e.g., corresponding to the left edge of the display side of the first display generating component), or the top edge of the display side of the second display generating component (e.g., corresponding to the top edge of the display side of the first display generating component) when viewed from the display side of the second display generating component 7102). In addition to updating the representation 7006 of the portion of the body of the first user 7202, the computer system also updates the representation of the state of the XR content (e.g., the overlay 7008 and / or the progress bar 7004) on the second display generating component 7102. For example, the progress bar 7004 is updated (e.g., Figure 7B Shown as 7004-b) to show the Figure 7A In some embodiments, the overlay 7008 representing the state of the XR content, as shown on the second display generating component 7102 (e.g., in FIG. 1 ), is also updated based on the current appearance of the XR content 7002 as shown via the first display generating component 7100. Figure 7B7008-b). In some embodiments, real-time updates of the appearance of portions of the first user's 7202 body are shown (e.g., changes and movements of the first user's face and eyes are shown behind the first display generating component 7202) and real-time or periodic updates of the state of the XR content shown by the first display generating component 7100 are shown, allowing others in the physical environment surrounding the first user 7202 to obtain information about the attention state of the first user 7202 and whether the current time is appropriate to talk to or interrupt the first user 7202. In some embodiments, while changes in the appearance of portions of the first user's 7202 body and the XR content are reflected by updates to the state information shown by the second display generating component 7102, any changes in the appearance of the physical environment (e.g., movement of the second user 7204 relative to the first display generating component 7100, the second display generating component 7102, and / or the first user 7202) are also reflected by the representation of the physical environment shown by the first display generating component 7100. In some embodiments, real-time updates optionally include updates with some computational and / or signal processing delay (e.g., delay of less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount imperceptible to most users).

[0223] Jump to Figures 7D to 7E , according to some embodiments, wherein 7A to 7B The scenarios and features described with respect to location A 7000-a and location B 7000-b, the first display generation component 7100 and the second display generation component 7102, the XR content 7002 and the state of the XR content, the computer-generated environment, and the physical environment (optionally, including the second user 7204) are respectively applicable to the following: Figures 7D to 7E Shown are location A 7000 - a and location B 7000 - b , first and second display generating components 7100 and 7102 , XR content 7002 and the state of the XR content, a computer-generated environment, and a physical environment (optionally including a second user 7204 ).

[0224] in addition, 7A to 7B The scenarios and features described in relation to the first user 7202, the part of the body of the first user 7202, and the representation 7006 of the part of the body of the first user also apply to the third user 7206, the part of the body of the third user 7206, and the representation 7208 of the part of the body of the third user 7206 (e.g., in Figure 7D is shown as 7208-a and in Figure 7E7208-b), except that the third user 7206 is different from the first user 7202, and based on determining that the first user 7202 meets the first criterion and the third user 7206 does not meet the first criterion, the representation 7208 of the portion of the body of the third user 7206 is aligned with the representation 7006 of the portion of the body 7002 of the first user (e.g., in Figure 7A is shown as 7006-a and in Figure 7B 7006-b). In some embodiments, the first criterion determines whether the respective user in question is a registered user of the computer system (also referred to as a primary user) or a guest user of the computer system. In some embodiments, a user becomes a registered user or a primary user after undergoing a registration process, which may involve one or more of the following: scanning the user's facial features, receiving subscription or registration information from the user to use the computer system as a registered user, and / or receiving valid verification information from the user to use the computer system as a primary user. In some embodiments, a user becomes a registered user or a primary user after the user has used the computer system with a frequency, duration, and / or incidence exceeding a threshold level. In some embodiments, a guest user is a user of the computer system who does not meet the first criterion to qualify as a registered user or a primary user. In some embodiments, a guest user is a user who has not yet undergone a registration process to scan the user's facial features, has not yet provided subscription or registration information to the computer system to use the computer system as a registered user (e.g., optionally, has provided subscription or registration information to use the computer system as a guest user), and / or has not yet provided valid authentication information to use the computer system as a primary user (e.g., optionally, has provided valid authentication information to use the computer system as a guest user). In some embodiments, once the user completes the necessary requirements to become a registered user or primary user (e.g., by undergoing a facial scanning process, undergoing a subscription and / or registration process, and / or using the computer system in a manner that qualifies the user as a registered user or primary user), the user may transition from being a guest user to a registered user or primary user. In some embodiments, the computer system does not necessarily have to have primary users or guest users functioning normally at a given time. For example, within a certain period of time (e.g., when the computer system first begins to be used, and / or after all previous primary users' information has been erased), the computer system may only have one primary current user and has not yet encountered any guest users; similarly, the computer system may only be used by guest users and has not yet encountered any primary users at a given time. As described herein with respect to 7A to 7B and Figures 7D to 7EThe different fidelity levels for displaying representations of portions of a user's body are effective when the computer system has encountered both registered users and guest users (e.g., on different occasions). In some embodiments, the computer system determines whether the current user is a registered user or a guest user based on determining whether the current user meets a first criterion. The computer system treats the current user as a registered user when the current user meets the first criterion and treats the current user as a guest user when the current user does not meet the first criterion. Thus, in some embodiments, even though the same person may use the computer system on multiple occasions over a certain time period, depending on whether the person meets the first criterion while using the computer system, the person may be identified as a primary user for some of those occasions and as a guest user for some other instances of those occasions.

[0225] like Figure 7D and Figure 7E As shown (and also as Figure 7A and Figure 7B ), when XR content 7002 including a representation of a three-dimensional environment is visible via the first display generation component 7100 (e.g., views of one or more virtual elements and / or representations of one or more portions of the physical environment are visible via the digital and / or optical transmittals provided by the first display generation component), the computer system displays, via the second display generation component 7102, a corresponding visual representation of a portion of a user's body that is in a position viewing the three-dimensional environment via the first display generation component 7100 (e.g., Figure 7D and Figure 7E A representation 7208 of a third user 7206 and Figure 7A and Figure 7B In some embodiments, the corresponding visual representation of the part of the user's body (e.g., Figure 7D and Figure 7E A representation 7208 of a third user 7206 and Figure 7A and Figure 7B The representation 7006 of the first user 7202 in the HMD is a computer-generated image (e.g., a realistic or stylized image generated based on a camera view of the user's face and / or eyes, a generic image corresponding to a user wearing the HMD or facing the internal display of the HMD, or a camera view of the user's face and / or eyes). In some embodiments, when the user is wearing the HMD and the user's face and / or eyes are facing the internal display of the HMD and the HMD blocks the direct view of the user's face and / or eyes by others and the user's direct view of the surrounding environment, a representation of a portion of the user's body is displayed via the external display of the HMD. In some embodiments, based on determining that the user meets the first criterion (e.g., the first user 7202 meets 7A to 7B), the computer system displays a first visual representation of the body part (e.g., 7A to 7B 7006 in the HMD). In some embodiments, the first criterion requires that the identity of the user satisfies a first condition in order to satisfy the first criterion (e.g., the user is a registered user of the computer system, the user has undergone a registration process for the computer system, the user's facial features and / or eyes have been previously captured and modeled during the registration process, and / or the user's identity has been verified by the computer system as a primary user of the computer system). In some embodiments, displaying a representation of the portion of the body of the first user that satisfies the first criterion includes displaying a computer-generated image or camera view of the first user's face and / or eyes based on a current appearance or a stored appearance of the user's face and / or eyes behind the HMD. Conversely, based on determining that the user does not satisfy the first criterion (e.g., the third user 7206 does not satisfy the first criterion (e.g., the third user 7206 is not a registered user of the computer system, the third user 7206 has not undergone a registration process for the computer system, the third user's facial features and / or eyes have not been previously captured and modeled during the registration process, and / or the third user's identity has not been verified by the computer system as a primary user of the computer system)), the computer system displays a second visual representation of the portion of the user's body (e.g., Figures 7D to 7E 7208 in the HMD), wherein the second visual representation has a lower level of fidelity than the first visual representation (e.g., optionally displaying a lower fidelity or generic computer-generated image of the third user's face and / or eyes based on the current appearance of the third user's face and / or eyes behind the HMD).

[0226] like Figure 7D and Figure 7E As shown (and also as Figure 7A and Figure 7B ), and displaying a corresponding visual representation of the portion of the user's body via the second display generating component (e.g., Figure 7A and Figure 7B A representation 7006 of the first user 7002 in Figures 7D to 7E ), the computer system detects a first change in the appearance of a portion of the user's body when the user is in a position viewing the three-dimensional environment via the first display generating component 7100. In some embodiments, the user (e.g., Figure 7A and Figure 7B The first user 7002 and Figure 7D and Figure 7EThe first change in the appearance of a part of the body of the third user 7206 in the example embodiment includes changes caused by movement of the user's eyes (e.g., opening, closing, blinking, squinting, winking, rolling eyes, and / or other intentional and / or unintentional eye movements), eyebrows (e.g., twitching, raising, lowering, raising, frowning, and / or other movements of eyebrows that accompany speech and / or form part of a facial expression), forehead (e.g., forming creases or wrinkles), nose (e.g., twitching, opening, and / or tightening), mouth (e.g., opening, smiling, closing, wrinkling, and / or other movements that produce speech and / or form part of a facial expression), and / or other parts of the user's face (e.g., cheeks, ears, and / or jaw). In some embodiments, if it is not the user (e.g., Figure 7A and Figure 7B The first user 7002 and Figure 7D and Figure 7E If there is a visual barrier between the third user 7206 in FIG and another person facing the user, the users (for example, Figure 7A and Figure 7B The first user 7002 and Figure 7D and Figure 7E The first change in the appearance of the part of the body of the third user 7206) is to change the appearance of the part of the body of the other person (e.g., Figure 7A 、 Figure 7B 、 Figure 7D and Figure 7E In some embodiments, the user (e.g., Figure 7A and Figure 7B The first user 7002 and Figure 7D and Figure 7E The first change in the appearance of the third user 7206) does not include visible changes caused by overall movement of the user's head relative to their body and / or overall movement of the user in the physical environment.

[0227] like Figure 7D and Figure 7E As shown (and also as Figure 7A and Figure 7B ), in response to detecting that the user is in a position to view the three-dimensional environment via the first display generating component 7100 (e.g., Figure 7A and Figure 7B The first user 7002 and Figure 7D and Figure 7E The computer system determines the appearance of a portion of a body of a third user 7206 in the example of FIG. 7206 based on the user's (e.g., Figure 7A and Figure 7B The first user 7002 and Figure 7D and Figure 7E The first change in the appearance of the part of the body of the third user 7206) is used to update the corresponding visual representation of the part of the body of the user displayed via the second display generation component 7102 (for example, Figure 7A and Figure 7B A representation 7006 of the first user 7002 in Figure 7D and Figure 7E In some embodiments, when updating the first visual representation of the portion of the user's body (e.g., Figure 7A and Figure 7B A representation 7006 of the first user 7002 in Figure 7D and Figure 7E When the appearance of the representation 7208 of the third user 7206 is determined, the computer system determines that the user meets the first criterion (for example, the first user 7202 meets the first criterion) based on the change in the appearance of the part of the user's body (for example, 7A to 7B to change the first visual representation of the body part (e.g., Figure 7A and Figure 7B In some embodiments, the real-time updates optionally include updates with some computational and / or signal processing latency (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users). Additionally, in some embodiments, when updating the first visual representation of the portion of the user's body (e.g., the first visual representation of the portion of the user's body, respectively, is updated), the real-time updates optionally include updates with some computational and / or signal processing latency (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds, and / or an amount that is imperceptible to most users). Figure 7A and Figure 7B A representation 7006 of the first user 7002 in Figure 7D and Figure 7E When the appearance of the representation 7208 of the third user 7206 in the embodiment is determined, based on determining that the user does not meet the first criterion (for example, the third user 7206 does not meet the first criterion), the computer system changes the appearance of the part of the user's body based on the first change (for example, Figures 7D to 7E to change the second visual representation of the body part (e.g., Figure 7D and Figure 7EThe present invention also provides a method for displaying the appearance of a representation 7208 of a third user 7206 in the HMD (e.g., displaying real-time updates of a lower-fidelity and generic computer-generated image of the third user's face and / or eyes based on the real-time movement of the third user's face and / or eyes behind the HMD during the corresponding time period). In some embodiments, the real-time updates and / or real-time movement of the third user's face and / or eyes behind the HMD optionally include updates and movements with some computational and / or signal processing latency (e.g., latency of less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users).

[0228] For example, according to 7A to 7B , in some embodiments, when the first user's eyes move (e.g., blink, close, squint, wink, look to the side, and / or move in other visibly ways), based on determining that the first user 7202 meets the first criterion, the computer system updates the computer-generated image or camera view of the first user's face and / or eyes (e.g., the portion of the computer-generated image or camera view corresponding to the user's eyes shows visual changes corresponding to the movement of the user's eyes) based on the real-time movement of the first user's eyes behind the HMD. 7A to 7B 7006 or another representation in ), wherein the visual changes are produced with the same or similar level of visual fidelity as the initially displayed computer-generated image or camera view of the first user's face and / or eyes. Figures 7D to 7E , in some embodiments, based on determining that the third user 7206 does not meet the first criterion, the computer system updates the lower-fidelity or generic computer-generated image of the third user's face and / or eyes (e.g., the portion of the lower-fidelity computer-generated image or generic image corresponding to the third user's eyes shows visual changes corresponding to the movement of the third user's eyes) based on the real-time movement of the third user's eyes behind the HMD. Figures 7D to 7E In some embodiments, when the first user 7202 meets the first criteria, the first visual representation (e.g., Figure 7A and Figure 7B The changes in appearance in the representation 7006 of the first user 7202 in the example more closely correspond to the real-time movements of the face and / or eyes of the first user, while the second visual representation (e.g., Figure 7D and Figure 7EIn some embodiments, the changes in appearance in the representation 7208 of the third user 7206 in the video image do not correspond closely to real-time movement of the third user's face and / or eyes (e.g., universal or limited movement). In some embodiments, the real-time movement of the user's face and / or eyes optionally includes movement of the user's face and / or eyes with some computational and / or signal processing delay (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users).

[0229] In some embodiments, as 7A to 7B As shown, Figures 7D to 7E In contrast, 7A to 7B The fidelity level of the representation 7006 of the part of the body of the first user 7202 in includes a first degree of information about the part of the body of the first user 7202, and Figures 7D to 7E The fidelity level of the representation 7208 of the portion of the body of the third user 7206 in the video includes a second degree of information about the portion of the body of the third user 7206 that is less than the first degree of information. For example, in some embodiments, the first degree of information includes the shape, color, eyelashes, and eyebrows of the first user's 7202 eyes, while the second degree of information includes a generic image of a pair of eyes that does not correspond to the shape, color, eyelashes, and eyebrows of the third user's 7206 eyes. In some embodiments, the first degree of information includes the color, shape, and / or size of the first user's 7202 eyes and the skin color around the eyes, and the second degree of information includes less information and / or less accurate information about the color, shape, and / or size of the third user's 7206 eyes and the skin color around the eyes.

[0230] In some embodiments, Figures 7D to 7E The representation 7208 of the portion of the body of the third user 7206 in FIG. 7 includes a darkening gradient 7210 that becomes darker as it gets closer to more identifiable portions of the body features (e.g., eyes, nose, and / or eye area) in the portion of the body of the third user 7206. In some embodiments, Figures 7D to 7E The representation 7208 of the portion of the body of the third user 7206 in the image is generated using a gradient filter that reduces the visual fidelity of the computer-generated image or generic image of the third user 7206 by a greater amount in a first portion (e.g., the top portion and / or the bottom portion) of the representation 7208, and reduces the visual fidelity of the computer-generated image or generic image of the third user 7206 by a lesser amount in a second portion (e.g., the middle portion and / or portions other than the first portion) of the representation 7208. In some embodiments, Figures 7D to 7EThe representation 7208 in includes a darker and / or blurrier gradient that becomes increasingly darker and / or blurrier as it gets closer to a more identifiable portion of a body of the third user 7206 (e.g., a first region of the body, such as an eye or an eye and an eyebrow).

[0231] In some embodiments, a curved processing mask is applied to a corresponding image of a portion of a user's body (e.g., a computer-generated image, a camera image, and / or a generic image of the portion of the body) to generate a corresponding visual representation (e.g., 7A to 7B A representation 7006 of the first user 7202 in Figures 7D to 7E or both). In some embodiments, the gradient mask used to reduce the visual fidelity of the representation 7208 of the portion of the body of the third user 7206 is a curved mask. In some embodiments, the corresponding image of the portion of the body includes an image on a curved surface (e.g., a contoured surface that mimics the contour of the user's face, a contoured surface of the second display generating component 7102, or a curved surface on which an image of the face or the eye region of the face is wrapped). In some embodiments, the mask is a curved mask that changes at least one visual characteristic on the curved surface of the corresponding image of the portion of the body (e.g., brightness, blur radius, resolution, color saturation, and / or other visual characteristics that affect the visual fidelity of the image). For example, in some embodiments, the corresponding image of the portion of the body includes an image showing the eyes and the facial areas between and below the eyes, as well as the area around the temple area, and these facial features are arranged on a curved surface that follows the contour of the face in the areas near the eyes, between the eyes, around the cheeks, and around the temples.

[0232] In some embodiments, the masking process changes some portions of the image of the portion of the user's body while leaving some portions of the image unchanged (e.g., a gradient filter is applied above the eyeline but not below the eyeline). In some embodiments, the gradient mask changes at least one visual characteristic (e.g., brightness, blur radius, resolution, color saturation, and / or other visual characteristic that affects the visual fidelity of the image) in a first region of the corresponding image of the portion of the body corresponding to a first physical feature of the user (e.g., an eye, an eye and an eyebrow, or other more identifiable and individual feature of a person), optionally without changing at least one visual characteristic in a second region of the corresponding image of the portion of the body that does not correspond to the first physical feature of the user. For example, in some embodiments, the corresponding image of the portion of the body includes an image showing the eyes and the facial area between and below the eyes, as well as the area around the temple area, and the gradient mask darkens and / or blurs the portion of the corresponding image corresponding to the eyes and eyebrows, while not darkening and / or blurring the portion of the corresponding image corresponding to the cheeks and temples. In some embodiments, the gradient becomes darker and blurrier as it moves from the area below the eyes closer to the eyes.

[0233] In some embodiments, 7A to 7B Representation 7006 of the first user 7202 and / or Figures 7D to 7E The representations 7208 of the third user 7206 in FIG. 7 , although displayed at different fidelity levels, all show the user (e.g., 7A to 7B The first user 7202 and Figures 7D to 7E A first physical feature (e.g., pupil, iris, and / or eye contour) of a user in a part of a body of a third user 7206) in the image.

[0234] In some embodiments, the computer system automatically (e.g., without explicit user input or request) detects whether the user currently using the computer system and viewing content via the first display generating component 7100 is a primary user or a guest user. In some embodiments, the computer system initiates determining whether the current user (e.g., a primary user) viewing content via the first display generating component is a primary user or a guest user in response to detecting that the user places the HMD on their head (or otherwise wears a wearable device (e.g., including the first display generating component, the second display generating component, the computer system, and / or components of any of the foregoing)). 7A to 7B The first user 7202 or Figures 7D to 7E In some embodiments, the computer system initiates a process of determining whether the current user (e.g., the third user 7206 in the first display generating component) viewing the content via the first display generating component in response to detecting the presence of an eye facing the display side of the first display generating component 7100. 7A to 7B The first user 7202 or Figures 7D to 7E In some embodiments, the computer system responds to detecting that a user (e.g., a third user 7206 in the display generation component 7102) meets the first criterion. 7A to 7B The first user 7202 or Figures 7D to 7E The determination of the current user (eg, the third user 7206 in FIG) viewing the content via the first display generating component is initiated by the presence of other people in the surrounding physical environment of the current user (eg, the third user 7206 in FIG). 7A to 7B The first user 7202 or Figures 7D to 7E The process of determining whether the third user 7206) meets the first criterion.

[0235] In some embodiments, the computer system utilizes data collected from one or more biometric sensors (e.g., sensors that capture biometric features such as irises, pupils, voiceprints, fingerprints, and / or facial features) to determine the identity of a user (e.g., 7A to 7B The first user 7202 or Figures 7D to 7E Whether the identity of the third user 7206 in satisfies the first criterion (for example, stored biometric information corresponding to the primary user or registered user).

[0236] In some embodiments, representations of parts of the user's body (e.g., 7A to 7B Representation 7006 of the first user 7202 and / or Figures 7D to 7E In some embodiments, the skin color of the user's face detected by one or more cameras is reproduced or used as a representation of the user's body part (e.g., 7A to 7B Representation 7006 of the first user 7202 and / or Figures 7D to 7E In some embodiments, based on determining that the current user does not meet the first criterion (e.g., the third user 7206 does not meet the first criterion), the computer system detects the skin color of the part of the user's body while the user is using the computer system to generate a representation of the part of the body. For example, in Figures 7D to 7E In some embodiments, based on determining that the first user meets the first criterion, the representation of the skin color of the part of the body detected in real time is included in the representation 7208 of the part of the body of the third user 7206. 7A to 7BIn some embodiments, the computer system does not detect the skin color of the part of the body in real time, but instead uses the stored skin color to generate the representation of the skin color in the representation 7006 of the part of the body of the first user 7202. In some embodiments, regardless of whether the user meets the first criteria, the computer system detects the skin color of the user in real time and generates a corresponding representation of the part of the user's body based on the detected skin color. In some embodiments, the real-time detection of the skin color includes detection with some computational and / or signal processing delay (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users). In some embodiments, the user is optionally given an opportunity and / or optional configuration option during the registration process to select and / or adjust the skin color and / or other display characteristics (e.g., brightness, texture, and / or other display characteristics) of the representation of the part of the user's body to be displayed via the second display generation component during the time the user views content using the first display generation component.

[0237] In some embodiments, based on determining that a user meets the first criteria (e.g., the first user 7202 meets the first criteria), the computer system displays a representation of the portion of the user's body based on stored skin colors of the portion of the body detected by the user during previous use of the computer system (e.g., the representation of the skin color of the portion of the body detected during a previous registration of the first user 7202 as a primary user of the computer system was included in the display). 7A to 7B Representation 7006 of a portion of the first user's body is shown).

[0238] In some embodiments, the skin color (and / or other display characteristics) of the part of the body presented in the representation of the part of the user's body is based on the skin color (and / or other visual characteristics) detected from the user's face (e.g., the skin color (and / or other visual characteristics, such as skin brightness and skin texture) from the face of the first user 7202 (e.g., detected in real time (e.g., optionally, taking into account some computational and / or signal processing delays (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is imperceptible to most users)), and / or detected from a previous registration session) used to generate 7A to 7B The skin color (and / or other display characteristics) of the representation 7006 of the first user 7202 in FIG, and the skin color (and / or other visual characteristics) from the face of the third user 7206 (e.g., detected in real time) are used to generate Figures 7D to 7E7206 in the representation 7208 of the third user 7206 in the display. In some embodiments, the real-time detection of skin color (and / or other visual characteristics) optionally includes the detection of skin color (and / or other visual characteristics) with some computational and / or signal processing delay (e.g., less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount that is not perceptible to most users). In some embodiments, instead of or in addition to the skin color (and / or other visual characteristics) of the user's face, the skin color (and / or other visual characteristics) of the user's hands or other parts of the body are used to generate the skin color (and / or other display characteristics) of the representation of the part of the user's body shown via the second display generation component 7102.

[0239] As about 7A to 7B and Figures 7D to 7E The computer system displays a representation of the user's body part in an animated manner (e.g., in the real-time movement of the user's body part) based on the real-time movement of the user's body part (e.g., the real-time movement of the eyes, eyeballs, eyelids, eyebrows, nose, cheeks and / or the area between the eyes and eyebrows). 7A to 7B A representation 7006 (e.g., a high-fidelity computer-generated image or camera view) of the eyes, eyeballs, eyelids, eyebrows, nose, cheeks, and / or the area between the eyes and eyebrows of the first user 7202 is animated in FIG. 7006 , and / or in FIG. Figures 7D to 7F A representation 7208 of the eyes, eyeballs, eyelids, eyebrows, nose, cheeks, and / or the area between the eyes and eyebrows of a third user 7206 is animated in the video (e.g., a high-fidelity computer-generated image or camera view). In some embodiments, real-time movement of parts of the users' bodies optionally includes detecting movement with some computational and / or signal processing latency (e.g., latency of less than 0.5 seconds, 0.25 seconds, 0.1 seconds, 0.05 seconds, or 0.01 seconds and / or an amount imperceptible to most users).

[0240] In some embodiments, the computer system allows a primary user (e.g., 7A to 7B In some embodiments, based on determining that the first user is the primary user of the computer system and that the user has prohibited the use of the high-fidelity representation 7006 of the body part when displaying the status associated with the first user via the second display generation component 7102, the computer system does not display the representation 7006 via the second display generation component 7102 to show the status information associated with the first user 7202. In some embodiments, the computer system does not display any representation of the body part of the first user 7202, or uses a low-fidelity representation of the first user 7202, such as Figures 7D to 7E A representation 7208 or a different general representation for a third user 7206.

[0241] In some embodiments, representations of parts of the user's body (e.g., 7A to 7B The representation 7006 of the first user 7202 or Figures 7D to 7E 7206) are displayed to the primary user (e.g., the first user 7202) and the guest user (e.g., the third user 7206) via the second display generation component 7102 at different fidelity levels, wherein the state of the XR content and / or the immersion level of the first display generation component 7100 (e.g., 7A to 7B and Figures 7D to 7E The representation of the overlay 7008 and progress bar 7004 in the figure is overlaid on the representation of the part of the user's body (e.g., overlaid on a display layer above the representation of the part of the user's body, and optionally separated from the display layer of the representation of the part of the user's body by a certain distance).

[0242] In some embodiments, representations of parts of the user's body (e.g., 7A to 7B Representation 7006 of the first user 7202 and / or Figures 7D to 7E In some embodiments, when the second user 7204 has moved relative to the second display generating component 7102 and is moving from a position corresponding to the second user 7204, the second user 7204 is a three-dimensional representation (e.g., having a contour corresponding to the contour of the user's face and / or the contour of the HMD; and / or having a curved surface that wraps around the user's eye area and temple area). Figure 7A 、 Figure 7B 、 Figure 7D and / or Figure 7E The scene shown compares the appearance of the representation of the portion of the user's body when the second display generating component 7102 is viewed from different angles (e.g., 7A to 7B Representation 7006 of the first user 7204 and / or Figures 7D to 7E The representation 7208 of the third user 7206 in the physical environment will appear different to the second user 7202 at different locations in the physical environment. According to some embodiments, this virtual parallax effect is achieved in, for example Figure 7G1 After Figure 7H1 as well as Figure 7G2 After Figure 7H2, where representations 7006-c and 7006-d of the first user 7202 have different positions when viewed by the second user 7204 from different positions relative to the display side of the second display generating component 7102. In some embodiments, the appearance of the portion of the body of the first user 7202 and / or the third user 7206 as seen by the second display generating component 7102 is different from the portion of the body of the first user 7202 and / or the third user 7206 as seen by the second display generating component 7102 as the first user 7202 and / or the third user 7206 moves relative to the second user 7204. Figure 7A 、 Figure 7B 、 Figure 7D and / or Figure 7E The scene shown will also look different for the second user 7204.

[0243] In some embodiments, the first display generation component 7100 and the second display generation component 7102 are positioned back-to-back in an HMD worn on the head of the first user or placed in front of the user's face (e.g., with their respective display sides facing different directions (e.g., substantially opposite directions or at an angle to each other)). In some embodiments, the second display generation component 7102 shows a visual representation of the first user's eyes that is generated based on a real image of the first user's eyes using one or more image processing filters. For example, the visual representation of the first user's eyes is optionally generated by reducing the opacity of the camera image of the first user's eyes, increasing its transparency, reducing its color saturation level, reducing its brightness level, reducing its pixel resolution, and / or reducing its color resolution. In some embodiments, the amount of modification applied to the various display characteristics of the corresponding camera image of the first user's eyes is optionally specified relative to the values of the various display characteristics of the overlay 7008 that indicates the state of the XR content being shown simultaneously. For example, when the overlay 7008 indicating the state of the XR content is relatively dark (e.g., having a first range of brightness values), the representation of the eyes is also made darker, more translucent, and / or less color saturated (e.g., having a second range of brightness values, a second range of transparency values, a second range of color saturation values selected based on the first range of brightness values); and when the overlay indicating the state of the XR content is brighter (e.g., having a second range of brightness values larger than the first range of brightness values), the representation of the eyes is made brighter, less translucent, and / or more color saturated (e.g., having a third range of brightness values, a third range of transparency values, a third range of color saturation values selected based on the second range of brightness values). In some embodiments, other display characteristics (e.g., color saturation, pixel resolution, color resolution, and / or hue) are used as a basis for selecting a range of values for the display characteristics of the representation of a part of the user's body (e.g., the user's face or eyes). In some embodiments, the representation of the first user's eyes is generated by applying one or more preset image filters, such as a blur filter, a color filter, a brightness filter, and / or other types of filters, which change the initial appearance of the first user's eyes when the second display generation component displays the representation. Similarly, according to some embodiments, the representation of the third user's eyes can be similarly generated from a generic image of the third user's eyes and / or using the first set of values of the filters to further reduce the fidelity level of the representation of the third user's eyes.

[0244] In some embodiments, the representation of the XR content shown by the second display generation component 7102 (e.g., overlay 7008 or another overlay or representation) is generated by applying a diffusion filter to the XR content displayed via the first display generation component 7100 (e.g., all visible content, only media content, or visible content that optionally excludes a pass-through view of the physical environment). For example, the overlay 7008 indicating the state of the XR content preserves the color and hue of the scene, but the outlines of objects in the XR content are blurred and not clearly defined in the overlay 7008. In some embodiments, the representation of the state of the XR content is semi-transparent and is not clearly defined by the representation of the portion of the user thereof (e.g., the portions of the user's image and the image shown in the overlay 7008, respectively). 7A to 7B The representation 7006 of the first user 7202 or Figures 7D to 7E In some embodiments, a graphical user interface element representing metadata associated with the XR content (e.g., a progress bar 7004, the name of the XR content, the name of the application associated with the XR content, and / or other user interface elements) is displayed by the second display generating component 7102 (e.g., displayed in the same display layer as the overlay 7008 indicating the state of the XR content or in a different display layer, and / or displayed in the same display layer as the representation of the portion of the user or in a different display layer). In some embodiments, the overlay 7008 indicating the state of the XR content and / or the representation of the portion of the user (e.g., 7A to 7B The representation 7006 of the first user 7202 or Figures 7D to 7E Graphical user interface elements representing metadata associated with the XR content are displayed with higher pixel resolution, higher color resolution, higher color saturation, greater opacity, greater brightness, and / or better defined outlines compared to representation 7208 of a third user 7206 in FIG.

[0245] In some embodiments, parts of the user's body (e.g., 7A to 7B The first user 7202 or Figures 7D to 7EThe eyes and / or face of the third user 7206 in the image (e.g., the user's eyes and / or face) moves relative to the first display generation component 7100 while the XR content 7002 presented via the first display generation component 7100 does not change. In this case, the representation of the portion of the user's body is optionally updated on the second display generation component 7102 without updating the overlay 7008 or progress bar 7004 of the XR content. In some embodiments, XR content is not displayed or is paused, and a user (e.g., the first user 7202 or the third user 7206) is viewing a pass-through view of the physical environment via the first display generation component 7100 without concurrently displaying the XR content; and the second display generation component 7102 optionally shows an update to a representation of a portion of the user's body based on a change in the appearance of the portion of the user's body (e.g., the first user 7202 or the third user 7206, respectively) (e.g., due to movement of the portion of the user's body or other visual changes of the user) without displaying a representation of the XR content (e.g., overlay 7008 or another representation), or shows a representation of the XR content (e.g., overlay 7008) in a static or paused state.

[0246] exist 7A to 7C and Figures 7D to 7E In the example scenario shown, the immersion level associated with the XR content and the attention state of the users (e.g., the first user 7202 and the third user 7206, respectively) are unchanged and correspond to intermediate immersion levels associated with the presentation of the XR content. In some embodiments, the immersion level associated with the presentation of the XR content and the corresponding attention state of the first user optionally change over a peri...
