    Abstract: A fixed-distance display system includes a light source configured to generate a light beam. The system also includes a light guiding optical element configured to propagate at least a portion of the light beam by total internal reflection. The system further includes a first inertial measurement unit configured to measure a first value for calculating a head pose of a user. Moreover, the system includes a camera configured to capture an image for machine vision optical flow analysis. The display system is configured to display virtual images only within a tolerance range of a single predetermined optical plane.

    Abstract: A dual source spatialized audio system includes a general audio system and a personal audio system. The general system includes a general audio processor and general speakers to produce general sound. The personal system includes a frame to be worn on a head of a user and a plurality of personal speakers attached to the frame. The personal system also includes a head pose sensor to collect head pose data of the user. The personal system further includes a head pose processor to determine a head pose of the user from the head pose data. Moreover, the personal system includes a personal audio processor to generate personal audio data based on the head pose of the user. The personal speakers generate personal sound corresponding to the personal audio data. The personal processor receives timing information/metadata from the general audio processor to synchronize the personal sound with the general sound.
