Tennis Volley app for iPhone and iPad

Enjoy a round of tennis volley shots in this controller free game. Simply stand in front of the device and swing your arms as the tennis ball approaches. Control the direction of the hit by the motion of your arm.

This game works using the front-facing camera, required for play. Motion is detected in the camera using accelerated computer vision.

For the technical enthusiast, this game is unique in its use of GPU computing for the accelerated computation of the Horn-Schunck Optical Flow that makes the app work in real-time.

Supported Devices: iPhone4 and iPad2 or higher due to the need for a front-facing camera.
