PingPongPlus

This paper introduces a novel interface for digitally-augmented cooperative play. We present the concept of the athletic-tangible interface, a new class of interaction which uses tangible objects and full-body motion in physical spaces with digital augmentation. We detail the implementation of PingPongPlus, a reactive ping-pong table, which features a novel sound-based ball tracking technology. The game is augmented and transformed with dynamic graphics and sound, determined by the position of impact, and the rhythm and style of play. A variety of different modes of play and initial experiences with PingPongPlus are also described.
