OHAJIKI: Flicking Gesture Recognition with a High Speed Camera

This paper describes a novel interaction technique that recognizes a finger flicking gesture for power adjustment input for a sports game, such as golf swing or hitting. Our system measures speed of the finger motion and direction of the gesture by using a high-speed camera and a high frame rate image processing technique. By using this system, users can adjust power and angle intuitively. We developed a 3D golf game using this interaction technique to provide an intuitive golf swing input.
