Physically Moving the Phone in Free Space

"We have developed a collection of mobile phone games that incorporate physical gesture interactions. Users interact with the game by physically moving the phone in free space. For example, in Pong, a user moves the phone left and right to control the paddle. The games do not rely on special motion sensors. Instead, they use the mobile phone’s camera as the motion detector. By using computer vision techniques like motion blur detection and optical flow it is possible to detect up to 6 degrees of freedom. We have developed three entertainment applications to explore this application domain. The first is a simple single player Pong game. The second is a Doodle application that demonstrates the various degrees of freedom. The third is a multiplayer version of the Pong game that leverages the Bluetooth capabilities available on many camera phones."
