<p>The present invention belongs to the field of man-computer interaction of touch screen terminals, and provides a touch screen terminal and a method and system for identifying hand gestures of the touch screen terminal. According to the method and system, a series of feature points of the hand gestures are collected through a touch screen, direction vector encoding is carried out on the feature points, an encoding result is matched with a reference template, so that symbols corresponding to the hand gestures are obtained, and symbols formed by touch screen sliding hand gestures of a user can be effectively identified. Compared with the prior art, the identification method is simple to implement and convenient for a user to operate, dispenses with supporting of a camera, which can lower costs, is insusceptible to surrounding light or a moving state of the touch screen terminal, and is high in the identification rate.</p> |
