Abstract

In this paper, we propose a novel gesture-based virtual keyboard (Gesture Keyboard) of QWERTY key layout requiring only one camera. Gesture Keyboard tracks the user's fingers and recognizes gestures as the input, and each virtual key of it follows a corresponding finger. Therefore, it is possible to input characters at the user's preferred hand position even if displacing hands during inputting. Because Gesture Keyboard requires only one camera to obtain sensor information, keyboard-less devices can feature it easily.
