Abstract: A camera assembly with two distinct magnifications is described. The camera assembly includes a lens assembly with two modules to perceive light. The first module includes two halves of different lens assemblies disposed together to provide two different optical paths and fields of view to obtain the two different optical magnifications. The second module includes a lens assembly common to the two halves of the first module. A biprism provides light separation for the two halves of the first module. Thus, light received and subjected to two different magnifications in the first module at a distal end of the camera assembly is further processed through the second module before being provided to a sensor. The biprism at the camera's distal end keeps the two different lens assemblies of the first module at the same viewing direction.

Abstract: The disclosed system may include a detachable capsule that includes a capsule-side capacitive plate. The system may also include a receiving antenna electrically connected to an antenna-side capacitive plate, and a capacitive sensor electrically connected to the capsule-side capacitive plate. The two plates may be coupled to each other and may transmit RF signals between them. The capacitive sensor may be configured to detect an amount of capacitance between the two capacitive plates. The system may also include an antenna matching tuner electrically connected to the capacitive sensor and to an antenna feed. Then, upon receiving capacitance measurements from the capacitive sensor, the antenna matching tuner may alter various parameters of the antenna feed including impedance matching parameters. Various other apparatuses and mobile wearable devices are also disclosed.

Abstract: Aspects of the present disclosure are directed to streaming interactive content from a native application executing at an artificial reality (XR) device into an artificial reality environment and/or to nearby XR device(s). A shell environment at an XR system can manage the software components of the system. The shell environment can include a shell application and a three-dimensional shell XR environment displayed to a user. An additional application, natively executing at the XR system, can provide a host version of content and a remote version of content. A two-dimensional virtual object displayed in the shell XR environment can display the host version of the content, and the remote version of the content can be streamed to a remote XR system. The remote XR system can display the remote content within another two-dimensional virtual object, for example in another shell XR environment displayed by the remote XR system.

Abstract: In particular embodiments, a computing system may access a particular image frame and corresponding depth information of a dynamic scene. The depth information is used to generate a point cloud of the particular image frame. The system may generate a first latent representation based on the point cloud. The system may access a sequence of image frames of the dynamic scene and a set of key frames. The system may generate, using a temporal transformer, a second latent representation based on tracking and combining temporal relationship between the sequence of image frames and the set of key frames. The system may access camera parameters for rendering the one or more objects from a desired novel viewpoint and generate a third latent representation. The system may train an improved neural radiance fields (NeRF) based model for free-viewpoint rendering of the dynamic scene based on the first, second, and third latent representations.

Abstract: A method for audio beam steering, tracking, and audio effects for an immersive reality application is provided. The method includes receiving, from an immersive reality application, a first audio waveform from a first acoustic source to provide to a user of a headset, identifying a perceived direction for the first acoustic source relative to the headset based on a location of the first acoustic source, and providing, to a first speaker in a client device, an audio signal including the first audio waveform, wherein the audio signal includes a time delay and an amplitude of the first audio waveform based on the perceived direction. A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a system to perform the above method, and the system, are also provided.
