Abstract

We propose a new room-sized immersive projection display. The display consists of a cylindrical screen that can be moved horizontally and vertically, allowing the user to easily change his/her field of view by moving the screen to any angle. The angle of the screen is measured by a motion sensor, and the projected stereo images are changed in response to the measured angle. With this cylindrical screen system, it is necessary to project a distorted image onto the screen to produce a correct image. We make the distorted image using a multi-pass rendering method. In addition, a magnetic sensor measures the position and angle of the user and the screen images are changed if the user moves.
