PingPongPlus, a digital project out of MIT, brings an element of interactivity to the traditional game of table tennis, with a surface that visually reacts to the game as it happens. Projectors work in conjunction with sensors that detect the movement of the ball, causing effects such as water ripples upon impact. The ball’s motion also influences the rhythm of the accompanying music. The MIT team hopes PingPongPlus will let players explore “new ways to couple athletic recreation and social interaction with engaging digital enhancements.”
