A Head Movement Image (HMI)-Controlled Computer Mouse for People With Disabilities

By Chen, Yu-Luen; Chen, Weoi-Luen; Kuo, Te-Son; Jin-Shin Lai; Disability and Rehabilitation, Vol. 25, No. 3, pp. 163-167
Publication Date: February 2003

Paper evaluates image processing and microprocessor technology created for the development of a head movement image (HMI)-controlled computer mouse system for people with spinal cord injuries. The system controls the movement and direction of the mouse cursor by capturing head movement images using a marker installed on the user's headset. Preliminary clinical trials have compared the system with an infrared-controlled mouse system on various tasks performed by nine people with spinal cord injuries. The preliminary results indicated that the HMI-controlled computer mouse system performed favorably when compared to the infrared system on both input speed and accuracy measures. Implications for future research and design improvements are discussed.
