Development of Gazing Interface for Operation of a Page Turner Machine

This paper describes a man machine interface based on gazing input without user´s body restrictions. Gazing points forward to the side directions were estimated by the relative distance of an iris and the outer corner of left and right eyes. Whether or not the user gazes the camera was recognized by the intersection of the two perpendicular bisectors derived by the position of a cornea and the eyelid edges. The suggested recognition system was applied to the operations of the page turner machine. It could judge the user´s states of both reading a book and operating the machine by the special feature points on an eye.
