Abstract: In one embodiment, a method by a computing system associated with an image sensor including a quad-Bayer color filter array includes accessing image-sensor data generated by the image sensor, where the quad-Bayer color filter array comprises sixteen sets of filters, each corresponding to a pixel location within a quad-Bayer pattern, splitting the image-sensor data into sixteen packed channels, where each of the sixteen packed channels corresponds to one of the sixteen sets of filters, producing three channels of interpolated pixels by processing the sixteen packed channels using a machine-learning model, where the three channels comprise red, green, and blue channels, and constructing an output image using the three channels of the interpolated pixels.

Abstract: Aspects of the present disclosure are directed to group travel between artificial reality (XR) destinations. Currently, users in an artificial reality (XR) experience cannot travel with a group to a specific destination or between destinations (e.g., to and from virtual worlds, levels, applications, etc.). Thus, some implementations assign users within a group in a multiplayer XR experience (e.g., a virtual lobby) a same session identifier. When the users select a destination, some implementations can provide a computing system hosting the destination with the session identifier associated with the users, such that the hosting computing system can ensure that the users travel to the same instance of the destination together. If a user does not already have the destination installed, some implementations can allow the user to acquire access rights to the destination, then travel to the same instance of the destination as the other users.

Abstract: In some examples, an apparatus may include a backlight unit (BLU) including an electronic integrated circuit layer, a photonic integrated circuit layer, a color conversion module, and a display interface layer. In some examples, a BLU may include at least one laser or may be configured to receive laser light from at least one external laser source. Laser light may be transmitted towards a portion of the display interface layer using the photonic integrated circuit. Color conversion modules may be used to convert the laser light into one or more desired colors. Example apparatus may be used in head-mounted devices such as augmented reality and/or virtual reality devices. Other devices, methods, systems, and computer-readable media are also disclosed.

Abstract: An apparatus that facilitates and/or supports stabilizing apparent azimuth angles of audio signals in environments of varying acoustic fidelity may include an eyewear frame dimensioned to be worn by a user. The apparatus may also include circuitry coupled to the eyewear frame and configured to (1) obtain an audio signal originating from a sound source in an environment of the user, (2) manipulate an azimuthal angle of the audio signal relative to a location of the sound source in the environment toward a midline feature of the user, and (3) provide the audio signal for auditory display to the user such that the manipulated azimuthal angle causes the user to perceive the audio signal as originating from the location of the sound source. Various other apparatuses, systems, and methods are also disclosed.

Abstract: Systems and methods are provided for using a gesture detected at a wrist-wearable device to cause presentation of camera data at a head-wearable device. One example method includes receiving, via one or more sensors of a wrist-wearable device worn by a user, data generated based on performance of an in-air hand gesture by the user. In accordance with a determination that the data indicates that the in-air hand gesture is a camera-control gesture, the method further includes causing presentation to the user, via a display of a head-wearable device that is worn by the user and that is in communication with the wrist-wearable device, of a representation of camera data from a camera that is in communication with one or both of the wrist-wearable device and the head-wearable device.

Abstract: Systems, methods, and devices for wireless sidelink operations may include a first device including a transceiver and one or more processors configured to configure a transmission power for a wireless sidelink (SL) transmission of a SL connection with a second device, where the transmission power is configured to be greater than a minimum transmission power. The one or more processors may transmit, via the transceiver, the wireless SL transmission to the second device according to the configured transmission power.

Abstract: Aspects of the present disclosure are directed to a process for applying, in a distributed manner, Auto White Balance (AWB) correction techniques to images acquired at an imaging device. AWB is used to adjust the color balance of an image to make the image look more natural and appealing to the viewer. AWB can neutralize color casts that may be present in an image, such as those caused by the lighting conditions or the camera's sensors. The absence of AWB correction can cause an image to have incorrect colors, such as a green tint, while a failure in AWB can often be perceived as the image having an incorrect color tint. In examples, at least a portion of the computational complexity involved in performing AWB correction techniques can be offloaded to a companion computation device, such as a coprocessing device.

Abstract: The disclosed computer-implemented method may include acquiring, from a client device within a real-world environment, information representative of the real-world environment, and transmitting the information representative of the real-world environment to a relocalization service. The method may further include receiving, from the relocalization service, (1) an anchor point that may include a mapped position within the real-world environment, and (2) a determined position within the real-world environment of a client device relative to the mapped position of the anchor point. The method may further include sending an identifier of the anchor point to an asset management service, and obtaining, from the asset management service, a digital asset. The method may further include presenting the digital asset at a position within an artificial environment relative to the mapped position of the anchor point. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: An acoustic device with a manifold architecture is described. The acoustic device includes a primary waveguide and a manifold. The primary waveguide has a first end, coupled to an acoustic sensor, and a second end, a port open to a local area. The port receives airflow from the local area that includes sound pressure waves from a sound source and turbulent pressure waves. The sound pressure waves and a first portion of the turbulent pressure waves are detected by the acoustic sensor. The manifold includes a plurality of waveguides that are coupled to a portion of the primary waveguide between the first end and second end. The plurality of waveguides has openings to the local area. The manifold vents a second portion of the turbulent pressure waves through the openings, and the second portion of the turbulent pressure waves is larger than the first portion of the turbulent pressure waves.
