Computer head control software to compensate for neck movement limitations

ABSTRACT

Computer head controls provide an alternative means of computer access for people with disabilities. However, a person's ability to use head controls may be reduced if his or her disability involves neck movement limitations. Software was developed which incorporates five methods of compensating for a user's neck movement limitation. This software will be used to evaluate and compare these methods, in order to determine their effectiveness in helping people operate a computer using head controls.
