Abstract
A near-eye display device comprises right and left display projectors, expansion optics, and inertial measurement units (IMUs), in addition to a plurality of angle-sensitive pixel (ASP) elements and a computer. The right and left expansion optics are configured to receive respective display images from the right and left display projectors and to release expanded forms of the display images. The right IMU is fixedly coupled to the right display projector, and the left IMU is fixedly coupled to the left display projector. Each ASP element is responsive to an angle of light of one of the respective display images as received into the right or left expansion optic. The computer is configured to receive output from the right IMU, the left IMU and the plurality of ASP elements, and render display data for the right and left display projectors based in part on the output.
