Abstract
A head-mounted projection display system is characterized by a pair of head-mounted low-power image projectors mounted adjacent the eyes of the viewer, and aimed to project in a direction along the line of sight of the viewer toward a high-gain, retro-reflective screen. Stereoscopic viewing is enabled by projecting separate images to the right and left projectors. The retro-reflectivity of the screen ensures that the right and left images will be returned to the right and left eye, respectively.
