Multi-Player Virtual Ping-Pong Game

In this paper we show how a motion capture system and feedback mechanism can be integrated into a virtual ping- pong game to create a multi-player platform. To trace the motion of each player, optical markers are attached to different places on each player's paddle. For tactile feedback, we designed a controller for a DC (Direct Current) motor, which is also attached to the paddle. This controller communicates with the game server through wireless Bluetooth technology. When the game server detects a collision between the paddle and ball, the controller receives the message from the game server and then triggers one of the respective paddle's DC motors to vibrate depending on the position of the impact on the paddle. During an exhibition many people positively responded to the game.
