Rear-projection Full-surround Spherical Display

Abstract

Visual immersion plays an important roll in virtual environment. This paper describes development of a rear-projection immersive spherical display. It has ability to display a panoramic image in omni-direction. Rear-projection screen has advantage in contrast of the image. The prototype display was compared with a front projected immersive spherical display named "Ensphered Vision." As a result, degradation of contrast due to an internal reflection of the projected image is significantly improved in this rear-projection display. This paper presents history and current research activities of the rear-projection full-Surround spherical display.
