Personal Viewer: a wide field, low profile, see-through eyewear display

摘要

A design for a low cost, wide field, low profile, light weight, full color, stereoscopic, see-through eyewear display called the personal viewer (PV) is presented. After a brief review of current methods and popular products, the principles of operation of the personal viewer are presented and several of the difficulties faced in implementation are discussed. Specifically, imaging is accomplished by covering each eye with a transparent semi-reflective half-ellipsoid, approximately 6cm in diameter and 7cm in length, with its lower focus at the user pupil and the upper focus at a two-axis scanner just above the user's brow. A 1mm collimated optical beam is directed onto the scanner mirror, from which a raster pattern is projected onto the inside surface of the ellipsoid and reflected into the user's pupil. The perceived source of the beam is the point of reflection, providing a 120 degree field breadth at each eye with a 60 degree overlap of the right and left fields where stereo fusion is available. Finally, a reduced bandwidth teleoperation support architecture is described where orientation sensors on the viewer control a dynamic mapping of the viewer display space onto a 360 degree image in response to user head motion.
