Human-interface by recognition of human gesture with image processing-recognition of gesture to specify moving direction

The authors developed a human-interface system to specify the moving direction by recognition of beckon motion. In this system, the recognition of gesture is performed by using a colour image processing system. The communication between persons are performed by using not only voice but also the gesture. In noisy environment, if machines can recognize the human gesture as a command, one operates the machine easily like making command to another person by his gesture. Then, the authors propose a communication method from human to machines by recognition of human gesture with an image processing system. This system makes communication with machines similar to communication with another person. This system needs no special environment, for example a data glove, data suit or a black background for monochrome image processing. It is necessary only that the operator wear a glove of a colour not found in the background
