    Interactive stereoscopic display for three or more users



    An ideal stereoscopic display system for multiple users is proposed. 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 of the users and generates distortion-free images for each eye of each user. The system consists of a normal display and a display mask, which has a hole in its center. The display mask is placed over the display surface at a suitable distance from it. 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, no user is able to see the image drawing areas of the other users because these areas are adequately occluded by the display mask. Accordingly, the display system can simultaneously provide intelligible 3D stereoscopic images for three or more moving observers without flicker or distortion.
