Abstract
This paper suggests an interface based on gazing input without user's body restrictions. The special feature points such as user's iris, inner and outer corner of the eye were detected by varying a threshold in the finalization procedure. Gazing horizontal directions were estimated by the relative position of a cornea with respect to the inner and outer corner of an eye. On the other hand, gazing vertical directions were derived by the locational relation among the three special feature points, namely, inner and outer corner of the eye, and iris. The suggested system was applied to the operations of the page turning machine. It was confirmed that the system could recognize the user's states of both reading a book and operating the equipment.
