Recognition of hand gestures using range images
Kazunori Umeda, Ichiro Furusawa, Saki Tanaka · 2002
Gesture is one of the important channels of man-machine interface. In the paper, methods to recognize hand gestures using range images are proposed. Five hand gestures: "come on", "go away", "turn right", "turn left" and "stop" are dealt with. A sequence of velocity vectors and normal vectors of a moving hand are extracted from range images, and gestures are recognized using the features. A recognition system is constructed which utilizes the recognition methods. Experiments to recognize persons' gestures using the recognition system are performed to show the effectiveness of the proposed methods and the recognition system.
