This thesis provides a baseline study for eye tracking user interface design for controlling a mobile robot. The baseline study is an experiment involving the use of a radio controller (RC) to drive the robot, while gaze data is collected from each subject monitoring the position of robot on the remote screen that displays the view for the turret-mounted video camera on the robot. Initial data from the experiment provides a foundation for interface design of actual control of the mobile robot by gaze interaction. Such an interface may provide Tele-presence for the disable. Patients with motor disability cannot use their hands and legs but only use their eye motions. Such applications of an eye tracking system can provide patients with much flexibility and freedom for search and identification of objects.
