3-D Computer Graphics System for Vision Research by Binocular Viewing

For the artificial realization and the application of the visual function of 3-D space perception, the better understanding of human visual mechanism is required strongly. The disparity and occlusion observed with binocular viewing seems to be the most important cues to get 3-D information. Then, the authors developed a simple stereoscopic display system using a time sharing display of left eye and right eye images with liquid crystal shutter. This system is composed of a simple small control circuit and has big advantages such as that the hardware can be applied to any types of display system and the software can be transplant to different type computer system easily. Then, the authors tried to apply this system for the vision research of 3-D perceptural function with binocular viewing.
