A practical ball sports platform combining dynamic body action with real-time computer graphics during ball play

We developed a new entertainment platform for digital sports, composed of a shock resistant rubber ball (M-digital ball) which comprises electronic sensors, a BLE wireless module, a communication program between the ball and a computer, and real-time computer graphics/sound contents. Six sensors and a BLE module are incorporated into a substrate which attached to a rubber structure inside the ball, which was designed to protect electronic parts and electrical connections so as elasticity of rubber and layer of the air in the ball protect circuit against strong shocks. Our system can specify the state of the ball through the wireless communication, getting value of sensors in real-time. Several computer graphics and sound contents were created using the system. We realized hands free sport platform which enable ball player to organize computer graphics and sound linked to player's dynamic body actions in real-time.
