Skill evaluator and trainer for electrically operated devices: an evaluation of the SET.

Our hypothesis was that the abilities of disabled people to control electrically-powered assistive devices could be reliably and objectively assessed by means of a portable, lightweight and inexpensive device, the Skill Evaluator and Trainer (SET), and that training on the SET would improve skill. Our approach was to use SET with a variety of interfaces and subject groups. SET produced a valid assessment of the skills of disabled people with particular interfaces, it improved skills when used as a training aid, and it was well accepted by clients and therapists.
