Abstract

Augmented Reality (AR) in multimedia gaming is a dynamic and exciting field of research. One of the challenges is to have multiple users interacting in the networked augmented reality environment. In recent years, camera-based body motion capturing console games, which captures the player's body movement to control the objects rendered by the computer, have been developed. In this paper, we present a system called, Tele-Table which allows multiple users to interact with each other through the network using real objects. Each player's set-up consists of an overhead mounted camera perceiving real objects, a plasma TV placed horizontally to act as a game table, and a computer. One of the most challenging tasks is data synchronization between two terminals. There are mainly three synchronization tasks we need to handle. They are temporal synchronization, spatial synchronization, and game states synchronization between the two terminals. We present these difficulties and present solutions and discussion to solve them. The design goals of the Tele-Table are real-time and realistic user experience. The features of the system are changeable background, using real objects, and real-time augmented reality gaming between two terminals. We outline the system, present the detailed description, and discuss current achievements.
