Abstract
IllusionHole is the ideal stereoscopic display system for multiple users. It allows three or more people to simultaneously observe individual stereoscopic image pairs from their own viewpoints. The system tracks the head positions of all users and generates images without distortion for each eye of each person. The system consists of a normal display and a display mask, which is equipped with a hole at the center. The display mask is located over the display surface at a suitable distance. By controlling the position of the image drawing area for each user according to the corresponding user's viewpoint, each user can observe the stereoscopic image pairs shown in an individual area of the display system with shutter glasses. On the other hand, each user is unable to see the image drawing areas of the other users because these areas are adequately occluded by the display mask. Accordingly, the IllusionHole display system provides intelligible 3D stereoscopic images for three or more moving observers simultaneously without flicker and distortion.
