A processor accesses a depth map and a first image of a scene generated using one or more sensors of an artificial reality device. The processor generates, based on the first image, segmentation masks respectively associated with a plurality of object types. The segmentation masks segment the depth map into a plurality of segmented depth maps respectively associated with the object types. The processor generates meshes using, respectively, the segmented depth maps. For each eye of the user, the processor captures a second image and generates, based on the second image, segmentation information. The processor warps the plurality of meshes to generate warped meshes for the eye, and then generates an eye-specific mesh for the eye by compositing the warped meshes according to the segmentation information. The processor renders an output image for the eye using the second image and the eye-specific mesh.

A projector sequentially generates light pulses to form a sparse grid array. The light pulses reflect off objects in an environment and are reflected towards a sensor array. The sensor array sequentially senses the reflected light pulses across pixels of the sensor array. A depth sensing system calculates depth information of objects in the environment based on the sequential nature of the pulse generation and the pulse sensing. The depth sensing system calculates depth information based on both the positional and temporal information of generated light pulses, and the positional and temporal information of sensed light pulses. The depth sensing system may generate a representation of the environment based on the depth information.

Aspects of the present disclosure are directed to creating virtual doors within artificial reality (XR) universes for traversal within that XR universe and between other XR universes. Users can create virtual doors that control access to their privately owned property (e.g., world, parcel, house, etc.) in an XR universe. For example, an owner of a virtual door can manually lock the door to prevent any user from entering their property through the virtual door. As another example, an owner of a virtual door can configure door permissions and/or privacy settings that serve as heuristics by which a door access control manager determines whether to authorize a particular user, XR world, and/or XR universe to access. The XR universe traversal system can control an execution environment to smoothly transition between different applications, thereby enabling a user to traverse between different XR universes without having to leave the XR environment.

MAPPING A REAL-WORLD ROOM FOR A SHARED ARTIFICIAL REALITY ENVIRONMENT
A room manager can generate mappings for a real-world room that support a shared XR environment. For example, the real-world room can include real-world objects and surfaces, such as a table(s), chair(s), wall(s), door(s), window(s), etc. The room manager can generate XR object definitions based on information received about the real-world room, object(s), and surface(s). For example, the room manager can implement a flow that guides a user equipped with an XR system to provide information for the XR object definitions, such as real-world surfaces that map to the XR object(s), borders (e.g., measured using a component of the XR system), such as borders on real-world surfaces, semantic information (e.g., number of seat assignments at an XR table, size of XR objects, etc.), and other suitable information. Implementations generate previews of the shared XR environment, such as a local preview and a remote preview.
Many users access artificial reality (XR) experiences through their mobile phones. However, it is difficult to translate XR experiences to a two-dimensional (2D) screen in a way that feels intuitive and natural. Thus, the technology can map an interaction plane in a three-dimensional (3D) scene to the 2D screen with as many affordances as possible, even if the plane is not parallel to the mobile phone. The plane can be a fixed surface or a dynamically changeable surface through which the user sends inputs through the 2D screen. The mapping of the plane to the 2D screen can control interaction with a virtual object on the interaction plane in the XR environment, enabling parity between the same experience on XR and non-XR interfaces.

Each of the one or more constraint metric tables may specify respective power levels for subsystems of the device according to a respective application or an application type of the respective application. The device may determine to operate the device at a reduced power level for a first application, based on a condition for the device satisfying at least one of a thermal threshold criteria or a power threshold criteria when the device operates at full power level. The device may apply a constraint metric responsive to determining to operate at the reduced power level, to cause a subset of the plurality of subsystems to adjust a power consumption level according to a first constraint metric table corresponding to the first application.

Systems and methods for streaming-based object recognition may include a device which transmits, to a server, video data and first coordinates of a first viewport for the device at a first time instance. The video data may include one or more objects in the first viewport. The device may transmit second coordinates of a second viewport for the device at a second time instance. The device may receive, from the server, data corresponding to the one or more objects within the second viewpoint. The data may be received in a sequence according to coordinates of the one or more objects relative to the second viewport. The device may render the data relative to the one or more objects within a third viewport at a third time instance.
