Haptic assistance to improve computer access for motion-impaired users

Research Output

This paper describes a pilot experiment which examines the effectiveness of using force-feedback technology to assist motion-impaired computer users in target selection tasks. Two measures to evaluate the effectiveness of force feedback assistance are proposed. The radius of curvature of the cursor path and the cursor speed along the path can capture differences in cursor movements that might be lost in a single measure such as time to target. Experimental results indicate that force-feedback implemented as nondirectional viscous damping has a beneficial effect for some, improving times to target by up to 50%. Future work includes developing other forms of haptic assistance, developing new measures for evaluation, and investigating the implications of kinaesthesic impairment.
