Chatterer Ping-pong Table

An intelligent ping-pong table is proposed in this paper, which can detect the position where the ball has dropped. The sensing system is constructed with piezoelectric sensors, an A-D converter, and a personal computer. Piezoelectric sensors are arranged in the four corners of the acrylic boards of the ping-pong table for sensing the dropped position. The system controls the illumination and the sound effect for the position where the ball dropped. The illumination and the sound effect are expectable for exiting the game. The position detecting method can be applied for sensing the position on a plane.
