Abstract
A vision-based gesture interface system, which employs an arbitrary quadrangle-shaped panel and a pointer tip like a fingertip as an intuitive input device. Taking advantage of the panel, the system can fulfill many tasks such as controlling a remote and large display, and simulating a physical keyboard. Users can naturally use their fingers and other pointer tips to issue commands and type texts. The system is facilitated by accurately and reliably tracking the panel and the pointer tip and detecting clicking and dragging actions.
