Abstract: Aspects of the present disclosure are directed to a VC/XR connection system that can establish and administer an XR space for a video call. The VC/XR connection system allows users to easily transition from a typical video call experience to the XR space, simply by putting on her artificial reality device. The VC/XR connection system can identify calendared video call events, establish corresponding XR spaces, and create a link between the video call and the XR space. Invitees to the video call that don an artificial reality device can be automatically taken into the XR space. The XR space can A) connect to the video call as a call participant, allowing the video call participants to see into the XR space and B) show a feed of the video call in the XR space, allowing users in the XR space to see the video call participants.

Abstract: In some examples, a device may include a backlight unit configured to illuminate a display. In some examples, a light source may direct light into an active photonic circuit. The active photonic circuit may include optical switches controllable to distribute the light to illuminate display zones. An active photonic circuit may include an arrangement of optical switches configured to allow particular zones to be raster scanned, for example, using light distribution and outcoupling further using a passive photonic circuit. The illumination intensity for each zone may be controlled using the optical switches and/or with variation of the light source intensity. In some examples, the illumination intensity for each zone can be varied based on the displayed content, allowing improved contrast ratios. In some examples, all zones may be illuminated simultaneously with a zonal illumination intensity based on displayed content. Other devices, methods, systems, and computer-readable media are also disclosed.

Abstract: Methods of assembling a head-mounted display (HMD) may include coupling a first digital projector assembly to an HMD frame, coupling a second digital projector assembly to the HMD frame, and then warping the HMD frame to optically align the first digital projector assembly with the second digital projector assembly. The warped HMD frame may be fixed such that the first digital projector assembly and the second digital projector assembly are optically aligned to within a predetermined threshold. Various other methods and systems are also disclosed.

Abstract: In particular embodiments, a computing system may initiate a scene alignment process to align a previous map of a scene with a current map of the scene. The system may send instructions to a user wearing an artificial-reality system to select a set of entities in the scene. The system may receive a selection of the set of entities in the scene. The system may determine a particular point in the scene based on an intersection of selected set of entities. The system may align the previous map with the current map based on the particular point in the scene. The system may load a scene model associated with the previous map into the current map.

Abstract: A near-eye display includes a display configured to display images, a memory device storing a compensation profile for compensating perceived brightness nonuniformity (e.g., brightness roll-off) of the display, and a display controller for controlling operations of the display. The compensation profile includes compensation values for modifying brightness in regions of the display to compensate the perceived brightness nonuniformity. The display controller is configured to control brightness of the display based on the compensation profile.
