Abstract
In this paper, we describe an interface based on gazing direction without user's body restrictions. In our system, gazing horizontal directions were calculated by the relative position of a cornea with respect to the inner and outer corner of an eye. Also, gazing vertical directions were estimated by the curvature of Bezier curve that was used four points, namely, inner and outer corner of the eye, and two control points. In the test trial, it was found that the gazing directions was roughly estimated using the developed system.
