Eye-trackers are emerging computer-input devices. This paper describes an experiment to measure the performance an eye- tracker. Detailed analysis of the system and experimental data show that for a typical 'move and select' task, the eye-tracker is two times faster than traditional computer input pointing devices like the mouse. Also, the cognitive start time for the eye-tracker is about 100-200 milliseconds less than that of other input pointing devices.
