Abstract: A method includes obtaining image data captured by an imaging device communicatively coupled with an artificial-reality system. The method includes generating a plurality of layers based on the image data including a first layer including an image of a real-world scene that includes a real-world object, and a second layer including a geometric representation of the real-world scene. The method includes, in accordance with determining that the real-world object meets digital-interaction criteria, generating a digital twin of the real-world object. The method includes, while causing presentation of a portion of one or more layers of the plurality of layers, in response to an interaction with one of the real-world object or the digital twin, updating the second layer such that the digital twin of the object is modified in response to the interaction, and ceasing to cause presentation of the portion of the real-world scene from within the first layer.

Abstract: The disclosed computer-implemented method may include coalescing and queueing, by an integrated circuit, messages in multiple message queues based on a latency tolerance level for the message. Additionally, the disclosed computer-implemented method may include transitioning, by the integrated circuit, a data transfer link to an active state based on the latency tolerance level for the message queue. This method may optimize power for the data transfer link by keeping it in a low power state for as long as possible. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Described herein is an example computer-readable storage medium that includes instructions that, when executed by an artificial-reality system that includes a wearable device, cause the artificial-reality system to perform operations. These operations include that after a user has donned the wearable device on a body part of the user, obtaining, based on data from a sensor of the wearable device, one or more fit characteristics indicating how the wearable device fits on the body part of the user. The operations also include that after the user has donned the wearable device on a body part of the user, in accordance with a determination that the user is interacting with an object within an artificial reality presented via the artificial-reality system using the wearable device, providing a fit-adjusted haptic response based (i) on the one or more fit characteristics and (ii) an emulated feature associated with the object.

Abstract: In one embodiment, a computing system may determine a gaze of a user of the computing system. The computing system may generate a foveated map based on the gaze to determine a sensor readout for an image sensor of the computing system. The foveated map may include several foveal regions. The computing system may determine the sensor readout including several zones corresponding to the image sensor based on the several foveal regions. Each of the several zones may indicate a readout resolution for an area of the image sensor for the respective zone. The computing system may capture a first image using the image sensor. The computing system may generate a modified first image based on the captured first image and the sensor readout.

Abstract: Disclosed herein are systems and methods related to using restricted target wake time in wireless communication. In one aspect, a first wireless communication device may configure a first field indicating (i) one or more traffic streams that are latency sensitive, and (ii) a direction of each of the one or more traffic streams between the first wireless communication device and a second wireless communication device. Each of the one or more traffic streams is to be communicated during a respective service period of a restricted target wake time (rTWT) schedule. The first wireless communication device may send a message including the first field to a second wireless communication device.

Abstract: Aspects of the present disclosure are directed to providing an augmented world environment model for an artificial reality (XR) environment. Some implementations of the present technology define how experiences will run on an XR system as a hierarchy of entities, including experiences, augments those experiences create, and an exclusive mode in which a particular experience takes control of the entire view. Some implementations can establish a framework for multiple experiences to interface with each other and to run in an XR ecosystem. This can improve upon traditional mobile and desktop operating systems by providing different states optimized for XR, which can include improved utilization of resources on an XR device, such as an XR head-mounted display. Experiences and augments can enter a particular state based on criteria, and can be, based on the state, processed differently by an operating system or provided with particular capabilities.

Abstract: An eye tracking system with in-optical-assembly plane illumination is described. Side-emitting light emitting diodes (LEDs) aligned with a plane of an optical assembly of a near-eye display device are used to illuminate the eye of a user and generate glints that can be detected by an eye tracking camera. A waveguide display of the near-eye display device projects computer-generated content to the eye. A mirror is positioned between the LEDs and the waveguide display to reflect light beams generated from the LEDs toward the waveguide display to mitigate any double glints that may cause ghost signals. A processor of the near-eye display device determines a position and gaze of the eye based on the captured image of the eye with the glints, and generates the computer-generated content for the waveguide display based on the position and gaze of the eye.

Abstract: In one embodiment, a system may comprise a plurality of photon sensors for detecting photons, a plurality of event registers for storing photon-detection events detected by the plurality of photon sensors during an exposure window after a laser event, and an SRAM disposed under the plurality of photon sensors. The SRAM may comprise a plurality of memory cells associated with each photon sensor of the plurality of photon sensors to store a histogram of photon-detection events. Each memory cell may store photon-detection events detected during a predetermined time period after the laser event. The SRAM may comprise an in-memory incrementor to update the plurality of memory cells based on the photon-detection events. The in-memory incrementor may read an event count stored in a selected one of the plurality of memory cells, increment the event count, and write the incremented event count back to the selected memory cell.

Abstract: An audio system determines latency for each client device of users participating in an artificial reality or augmented reality environment. The latency determined for a client device accounts for latency of a communication channel used by the client device to exchange data, as well as time for the client device to perform computational tasks. The audio system determines a distance in the artificial reality environment between a user's avatar and an audio source for audio data and adjusts one or more transfer functions for generating audio content for the user to account for effects of the latency determined for the user's client device on the audio content. In some embodiments, the audio system modifies a distance in the artificial reality environment between the user's avatar and the audio source to compensate for latency of the user's client device.
