| Abstract(in English) | This paper presents a virtual push-button interface created by drawing a shape or line in the air with a fingertip. As an example of such a gesture-based interface, we developed a four-button interface for entering multi-digit numbers by making pushing gestures within an invisible 2x2 button matrix inside a square drawn by the user. Trajectories of the fingertip movements entering randomly chosen multi-digit numbers are captured with a 3D position sensor mounted on the tip of the forefinger. We propose a statistical segmentation method for the trajectory of movements and a normalization method, associated with direction and size of gestures. The performance of the proposed method is evaluated in HMM-based gestures recognition. Recognition rate of 60.0% was improved to 91.3% after applying the normalization method. |
