Abstract

Presented in this paper is an immersive and interactive entertainment environment which integrates tiled display wall and motion tracking techniques. A fast calibration method is proposed to achieve geometry alignment and color consistency of the tiled display wall. A robust motion tracking algorithm is designed to obtain the player's moving direction and speed from video streams captured by a web camera. The tracking results are finally used to control the avatar in a virtual scene. The proposed system provides a low-cost and easy to install human-computer interaction environment.
