Pointing Device for Physically Handicapped People Operated by the Posture of Head.

Data input devices for physically handicapped people have already been developed. One simple device detects the blowing action of the operator as input signals to select desired menu items. Another advanced device detects eye movements as input signals. One problem associated with these advanced data input devices is that a lot of times is required to input items. In this work a pointing device operated by the posture of head is presented. An important feature of our device is that the operator can input items immediately by turning his head toward desired items displayed on CRT monitor.
