Abstract: A mixed reality system including a head-mounted display (HMD) and a base station. Information collected by HMD sensors may be transmitted to the base via a wired or wireless connection. On the base, a rendering engine renders frames including virtual content based in part on the sensor information, and an encoder compresses the frames according to an encoding protocol before sending the frames to the HMD over the connection. Instead of using a previous frame to estimate motion vectors in the encoder, motion vectors from the HMD and the rendering engine are input to the encoder and used in compressing the frame. The motion vectors may be embedded in the data stream along with the encoded frame data and transmitted to the HMD over the connection. If a frame is not received at the HMD, the HMD may synthesize a frame from a previous frame using the motion vectors.

The wake control system may assess a first wake criterion with low power, assess a second wake criterion with higher power than the first wake criterion upon satisfaction of the first wake criterion, and cause the head-mounted display unit to operate in the high-power state upon satisfaction of the second wake criterion.

Abstract: Methods and apparatus for spatial audio navigation that may, for example, be implemented by mobile multipurpose devices. A spatial audio navigation system provides navigational information in audio form to direct users to target locations. The system uses directionality of audio played through a binaural audio device to provide navigational cues to the user. A current location, target location, and map information may be input to pathfinding algorithms to determine a real world path between the user’s current location and the target location. The system may then use directional audio played through a headset to guide the user on the path from the current location to the target location. The system may implement one or more of several different spatial audio navigation methods to direct a user when following a path using spatial audio-based cues.
