Accessibility of computers is the essential in today's Information Society. Some of physically disabled persons have difficulties to use computers, because they can not operate normal keyboards prepared as a general input device. Eight types of specially designed keyboard for physically disabled persons have been experimentally developed to compensate their physical disabilities. Result of clinical testing of these keyboards, applied to three cervical cord injured (CCI) clients and three cerebral vascular accidents (CVA) clients, indicates following items. (1) The special keyboards are siginificantly more effective, for CCI clients who use sticks to operate a keyboard, than normal keyboards. (2) There is not significant difference, between the special keyboards and normal keyboards, for CCI clients who operate each keyboard by their own hands or fingers without any assistive devices. (3) The specail keyboards are siginificantly more effective, for CVA clients who use their non-right hands or fingers for operating, than normal keyboards. (4) There is not significant difference, between the special keyboards and normal keyboards, for CVA clients who operate each keyboard by their right hands.
