The purpose of the study was to develop assessment items for computer access of persons with severe physical disabilities, who have serious difficulties using standard keyboards and mice, so that they could find systematically computer input assistive devices or alternative input methods. To do so,we constructed assessment items based on three assessment tools for computer access or assistive technology needs used in the U. S. Then, a pilot test of these assessment items was conducted by two graduate students majoring in rehabilitation technology and one researcher. These assessment items also were validated by two special education teachers and one physical therapist (therapeutic education teacher). The items were overall adequate. Comments from the pilot test conductors and teachers validated the items were analyzed through in-depth classification and categorization and reflected in modifying process for the final assessment items. Assessment items of 60 in six categories were finalized with basic information of 17 items, seating position for using a computer of 11, environment for using a computer of 8, keyboard use of 13, mouse use of 10, and switch use of 11. A future study on computerized assessment tool was suggested to collect precise data on speed and accuracy of using keyboards, mice, and switches.
