Head-operated computer controls provide an alternative means of computer access for people with disabilities who are unable to use a standard mouse.
However, a person's disability may limit his or her neck movements as well as upper extremity movements.
Software was developed which automatically adjusts the interface sensitivity to the needs of a particular user.
This adaptive software was evaluated in two stages.
First, 16 novice head-control users with spinal-cord injury or multiple sclerosis used head controls with and without the adaptive software.
The adaptive software was associated with increased speed in standardized icon selection exercises (p < 0.05).
A small increase in accuracy was also observed.
In addition, five current head-control users evaluated the software in a real-world setting.
One of these five subjects perceived an improvement in comparison to his current head-control system.
