Abstract
We propose a head-tracking autostereoscopic display system based on magnetic-sensor tracking of the viewer's side-to-side location, and optical slewing of a stereoscopic image-pair array projected onto a lenticular screen so as to keep the images received by the viewer's eyes distinct. Viewer distance changes are accommodated by slight magnification changes of the projected image array. A high-definition-TV LCD projector is used with a 178-cm (70-in.) lenticular sheet (diagonal measurement) to provide impressive computer-generated 3-D images over a particularly wide viewing zone. The system finds application in a virtual-space teleconferencing system that requires a large-scale stereoscopic display without the use of special viewing glasses.
