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.
