Head-operated computer controls: effect of control method on performance for subjects with and without disability

摘要

Head-operated computer controls provide an alternative means of computer access for people with physical disabilities. A person's ability to use such head controls may be reduced if he or she experiences neck movement limitations. Five experimental methods of compensating for neck movement limitations were evaluated in comparison to a standard head control interface. Twenty- two subjects without disabilities and three subjects with multiple sclerosis performed icon acquisi- tion exercises using the standard interface and each of the five experimental compensation methods.
