Abstract: A head-mounted display (HMD) is wirelessly coupled to a console or a relay depending on the relative positions of the HMD, the console, and the relay. The HMD communicates wirelessly with the console using a beam that is oriented in a particular direction. As the position of the HMD changes, the quality of the communication link between the HMD and the console may degrades. In response to the degradation, the HMD forms a communication link with a relay, which operates as an intermediary between the HMD and the console. The relay communicates with the HMD over a dedicated communication channel that is isolated from the communication channel over which the relay communicates with the console. An RF signal path with calibration features in the relay iteratively adjusts a feedback reduction parameter until the effects of the undesirable feedback are eliminated.

Abstract: A head-mounted display (HMD) (e.g., VR headset or AR headset) displays a 3D virtual scene and includes a mirror to increase a field of view (FOV). The HMD includes an electronic display that further includes a primary display and an extended display, where the content displayed on the primary display is presented to the user's eye at an exit pupil through a lens and content displayed on the extended display is presented at the exit pupil through reflections of the mirror. The mirror is positioned between the exit pupil and the electronic display such that the mirror reflects light originating from the extended display and provides the reflected light to the exit pupil to increase the FOV. The combination of the content viewed through the lens and that of the reflected light of the extended display results in an FOV larger than when the content is viewed only through the lens.

Abstract: A head-mounted display (HMD) device includes a plurality of deformation sensors attached to a liner formed around a periphery of a HMD, adopted for direct or indirect contact a user's face. The deformation sensors measure deformations of the liner caused by movement of an upper portion of a user's face when the user is wearing the HMD. The deformation sensors are strain gauges embedded in or otherwise coupled to the liner of the HMD. The sensors translate muscle movements of the upper face of the user to changes in the bending strain and radius of curvature on the surface of the strain gauges. The HMD includes a module that reconstructs and projects a facial animation model of the user based on signals from the deformation sensors while the HMD is in use by the user.

The method includes obtaining the calibration data for correcting non-uniformity of a display panel of the HMD at various brightness levels and storing the data. In response to receiving a request for providing content to be presented on the HMD, the host applies the calibration data based on a luminance level of content being rendered to correct for any non-uniformities of the one or more display panels while rendering the content for display.
