Vision-based hand gesture interactions for large LCD-TV display tabletop systems

The advent of the LCD displays and computer vision technology has encouraged the development of large interactive systems that allow several users to interact simultaneously. We introduce a vision-based hand gestural interactive tabletop system which provides high definition display output and can recognize several standard gestures and track hand motion by using a camera and computer vision technology. The system focuses on the fast recognition and tracking techniques minimizing response time between users and multimedia which is especially important for motion games with immediate and large hand movements. A prototype system, which is capable of recognizing 5 gesture types and tracking hand motion in real time, was built. A demonstration game, Virtual Air Hockey, was built under the prototype system to demonstrate interactive techniques which receive positive user feedback.
