Abstract: Methods and systems described herein are directed to a virtual web browser for providing access to multiple virtual worlds interchangeably. Browser tabs for corresponding website and virtual world pairs can be displayed along with associated controls, the selection of such controls effecting the instantiation of 3D content for the virtual worlds. One or more of the tabs can be automatically generated as a result of interactions with objects in the virtual worlds, such that travel to a world, corresponding to an object to which an interaction was directed, is facilitated.

Abstract: An optical element includes a first optical substrate, a second optical substrate overlying at least a portion of the first optical substrate, a liquid crystal layer disposed within a cell gap between the first optical substrate and the second optical substrate, and a plurality of carbon nanotube pillars extending between the first optical substrate and the second optical substrate across the cell gap. The carbon nanotube pillars may have an aspect ratio of at least approximately 2:1, and may be configured to maintain a uniform cell gap thickness.

Abstract: An audio device includes a first speaker and a second speaker. A front surface of a membrane of the second speaker faces a rear surface of a membrane of the first speaker. The membrane of the first speaker moves in an opposite direction than the membrane of the second speaker when the audio device outputs audio content. This configuration maintains isobaric pressure for a back volume shared between the first speaker and the second speaker, reducing vibration of the audio device when outputting audio content.

Abstract: In holographic calling, it is difficult to capture the eyes of a caller due to lighting effects on an artificial reality (XR) headset. However, it can be important to capture the eyes when rendering the caller as they can show emotion, gaze, physical characteristics, etc., that aid in natural communication. Thus, implementations can capture the eyes of the caller using an external image capture device by briefly turning off the lighting effects on the XR headset. Some implementations can trigger the image capture device to capture an image of the eyes by temporal multiplexing in which timers on both the image capture device and the XR headset are synchronized. In other implementations, the image capture device can be an event-based camera that is automatically triggered to capture an image of the eyes based on a detected pixel change caused by deactivation of the lighting effects on the XR headset.

Abstract: Systems and methods for configuring reduced repetitions for ultra-wideband (UWB) physical layer headers may include a first UWB device that generates a packet including a first header and a second header. The first header may include a plurality of bits indicating a data rate and an encoding scheme of a payload of the packet. The first UWB device may transmit the packet to a second UWB device. The second UWB device may receive and decode the packet according to the encoding scheme and the data rate.

Abstract: Aspects of the disclosure are directed to an artificial reality (XR) browser configured to trigger an immersive experience. Implementations display an element at a browser chrome of the XR browser when an immersive experience is loaded. For example, the XR browser can include an application programming interface (API) that supports configuration of a browser chrome element by components of a webpage. The API call can cause the display of the browser chrome element, change a display property for the browser chrome element, or configure the browser chrome element in any other suitable manner. Upon receiving input at the browser chrome element (configured by the API call), the XR browser can transition from displaying a two-dimensional panel view of a webpage supported by loaded web resources (e.g., hypertext transfer protocol (HTTP) pages, graphic images, etc.) to a three-dimensional environment supported by preloaded immersive resources (e.g., three-dimensional models, graphic images, etc.)

Abstract: An eye tracking system includes, in addition an eye tracking camera, one or more illuminator assemblies. The illuminator assemblies include a light source (e.g., a light emitting diode (LED), a laser source, etc.) and provide infrared or near-infrared (NIR) light. The radiated light from the light source is received at and provided as a beam shaped light by a beam shaping element onto an eye box. A direction and/or a spread of beam shaped light is controlled by the beam shaping element. A collimator may be used between the light source and the beam shaping element to collimate the radiated light onto the beam shaping element for increase efficiency. The beam shaping element may be a diffractive optical element (DOE), with an angle and shape of diffractors selected based on a designated direction and spread of beam shaped light.

Abstract: The solution can provide a switch-configurable diplexer architecture for dual-band communication. A first diplexer can have a first band for an interlink connection between an access point and a device and a second band for an intralink connection between the device and a second device. The first band and the pass band can be separated by a first gap. A second diplexer can have a third band for the first interlink and a fourth band for the intralink. The third band and the fourth band can be separated by a second gap. The first band and the third band, as well as the second band and the fourth band, can partially overlap. A processor can identify that the access point has selected, for the interlink connection, a first channel corresponding to the second gap and determine, responsive to the identification, to use the second diplexer for the intralink connection.

Abstract: In particular embodiments, a computing system may receive a color image captured by a color camera and a monochrome image captured by a monochrome camera. The color camera and the monochrome camera are associated with an artificial reality system. The computing system may compute, for each of the color and monochrome images, histogram statistics and perform, based on the histogram statistics, tone map matching to normalize the monochrome image with respect to the color image. The computing system may perform local motion estimation to calculate motion vectors indicating pixel correspondence between the normalized monochrome image and the color image. The computing system may generate a mono-color merged image for display on the artificial reality system by adding, for each pixel in the normalized monochrome image, color information extracted from corresponding pixel in the color image using the motion vectors.

Abstract: Implementations are directed to uniform resource locator (URL) access to assets within an artificial reality universe on both two-dimensional (2D) and artificial reality (XR) interfaces. Implementations can use a uniform URL schema to represent the asset, the URL being semantically meaningful and reflective of the hierarchical structure of the location of the asset within the XR universe. Accessing the URL from a 2D interface can lead the user to a landing page from which the user can choose to continue and visit the world from the 2D interface, or to instead visit the world from an XR interface. When accessing the URL from the XR interface, the user can see prefetched information regarding the destination that is automatically presented to the user in a sensible manner, such as in a rendering of a travel portal, which the user can activate to render the destination.
