Many communication aid systems have been developed for severely physically handicapped people like ALS patients. The eye-gaze input system is being studied as an interface for a communication aid that can operate a computer with eye movement alone. Conventional eye-gaze input systems, however, can harm users. This is due to the use of infrared rays on the eyes to detect the eye-gaze. The prolonged irradiation could potentially cause eye damage such as glassblower's cataract, retinitis solaris, or dry eyes. We propose an eye-gaze input system using a personal computer and a home video camera for eye-gaze detection under natural light. The system detects the eye-gaze using image analysis based on the limbus tracking method, and it does not require special image processing units or sensors. The system is safe, compact and easy to use. キーワー ド:視 線入力,画 像解析,自 然光,強 膜反射法,コ ミュニケーション支援,福 祉機器
