Many systems to aid communication have been developed for seriously physically handicapped people, such as ALS patients. An eye-gaze input system is currently being evaluated as a new interface. This system can be used to operate a computer with eye movement only. Most conventional eye-gaze input systems use infrared rays on eyes to detect eye-movement. However, prolonged irradiation could damage eyes. We developed a new eye-gaze input system with multi-indicators using a personal computer and a home video camera to detect eye-gaze under natural light. This system does not require special devices for detecting eye-movement. The results of our system analisys show the limit of the vertical resolution is between 5 and 7 indicators.
