Optical measurement devices for eye movements are generally expensive and it is often necessary to restrict user head movements\nwhen various eye-gaze input interfaces are used. Previously, we proposed a novel eye-gesture input interface that utilized\nelectrooculography amplified via an AC coupling that does not require a head mounted display. Instead, combinations of eyegaze\ndisplacement direction were used as the selection criteria. When used, this interface showed a success rate approximately\n97.2%, but it was necessary for the user to declare his or her intention to perform an eye gesture by blinking or pressing an enter\nkey. In this paper, we propose a novel eye-glance input interface that can consistently recognize glance behavior without a prior\ndeclaration, and provide a decision algorithm that we believe is suitable for eye-glance input interfaces such as small smartphone\nscreens. In experiments using our improved eye-glance input interface, we achieved a detection rate of approximately 91% and\na direction determination success rate of approximately 85%. A smartphone screen design for use with the eye-glance input\ninterface is also proposed.
