Study on a stereoscopic display system employing eye-position tracking for multi-viewers

ABSTRACT We propose a new autostereoscopic display system employing an eye-position tracking technique for multi-viewers, who do not need to wear 3-D glasses. We also describe the developed stereoscopic projectors and the lenticular screen design for this system. In this system, the 3-D screen consists of two lenticular screens and a diffusion layer. Each 3-D projector which corresponds to a viewer consists of two projectors for right and left images. The viewer's positionsare detected, and the 3-D projector moves according to the viewer's movement. 1. INTRODUCTION We are conducting basic research on a virtual space teleconferencing system [1] that achieves a sense of reality. Such a system needs large-scale stereoscopic displays. Stereoscopic displaytechniques requiring special glasses cause users to feel uncomfortable and tired, and reduce thefeeling of naturalness. In the field of teleconferencing, a no-glasses technique using a lenticularscreen was found to be superior to holography and a volume-scanning-type 3-D display in terms of
