Implementation and evaluations of vision-based finger flicking gesture recognition for tabletops

Finger flicking is a familiar finger movement, and we often flick a small object on the table with a finger in our daily life. We developed a flicking gesture recognition system called the dasiaOHAJIKI interfacepsila, which can track very rapid flicking movements using a high-speed camera, and estimate the flicking power and direction in real time. In this paper, we describe the recognition techniques of the flicking gesture on a large LCD to produce a novel tabletop system that enables us to use the gesture to flick a virtual marble on the table. Moreover, we also present an evaluation of a vision-based flicking tabletop system as an entertainment application.
