In the present paper, we present a novel gaze-controlled interface. It allows the user to magnify and inspect any part of an image by just looking at the part in question and subsequently shifting gaze to another window. No manual input is required to control this process. The interface was empirically evaluated in a multi-session experiment employing a comparative visual search tasks that required several steps of zooming in and out of a search display. Each participant's performance was assessed separately for using gaze control and using a mouse as the input device and compared between conditions and across sessions. The results demonstrate that participants' performance with the gaze-control interface is quite comparable with a standard mouse input device and that using the gaze-control interface can be learned very quickly.
