Computer interface device for handicapped people using head movement
Takakazu Ishimatsu, Naoki Irie, Osamu Takami · 2002
In this paper we propose a computer interface device for physically handicapped people, which enables the operator to communicate with the computer without typing on the computer keyboard. Input signals of the interface device are movement of the head. The movement of the head is used as a positioning signal of the computer cursor on the computer monitor. The system is realized on one field programmable gate array (FPGA) in order to realize the system in a compact body. Using this interface device, we built an environmental control system and also a word processing system. Experimental results reveal the applicability of our system to physically handicapped people.
