Evaluation of upper extremities\u27 physical capability for a physically disabled person is essential to select the most suitable technical aid for him or her. In the field of medical rehabilitation, ADL (Activities of Daily Living) test has been used as the standard evaluation method for the physically disabled. However, this can reveal only the physical capability in the daily activities which wouldn\u27t include the use and the operation of technical aids. The purpose of this research program is to find an objective method for evaluating physical capabilities of upper extremities for the physically disabled who needs technical aids. As the first step of the research program, reaction time for visual stimulus has been mesured by using thirty non-disabled students as clients. A testing board with thirty six switches, each of them has a LED, has been used to give visual stimulus. The time between the activation of a LED and putting off the LED by each student\u27s operation has been mesured as the reaction time. Result of this indicaltes following items. (1) Auditory feedback is significantly effective to reduce reaction time for the visual stimulus. (2) No significant differences were observed in reaction time between the operation by right hand and the operation by left hand. (3) The activation of the upper left switch and upper right switch took more time than it of other switches. On the other hand, activation of switches in lower middle area on the board took less time than those on other areas

Accessibility of computers is the essential in today\u27s 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
