Abstract :
A hybrid hands-off human computer interface that uses infrared video eye gaze tracking (EGT) and electromyogram (EMG) signals is introduced. This system combines the advantages of both sub-systems, providing quick cursor displacement In long excursions and steady, accurate movement in small position adjustments. The hybrid system also provides a reliable clicking mechanism. The evaluation protocol used to test the system is described and the results for the hybrid, an EMG Only interface, and the standard hand-held mouse are described and compared. These results show that the hybrid system is, in an average, faster than the EMG-only system by a factor of 2 or more.
