    Eye-Based Interaction in Graphical Systems: Theory & Practice

Course Organizer(s):



    Basic knowledge of 3D computer graphics such as that provided in the Fundamentals Seminar. Experience with virtual reality application programming and knowledge of VRML may be helpful.

    Specifications of eye tracking hardware, emphasizing state-of-the-art, video-based eye trackers, principal modes of gaze-contingent applications (interactive or diagnostic), design of software drivers and integration of eye trackers in graphical systems, basics of eye movements and eye movement signal characterization, and potential gaze-contingent applications.

    Interactive techniques associated with the use of an eye tracker, a device that delivers real-time coordinates of the user’s gaze. This course introduced attendees to theoretical aspects of dynamic human vision, the characteristics of eye movements, and visual attention. It presented system integration techniques, including a description of available video- based eye-tracking hardware; requirements for development of software drivers; techniques for developing real-time, interactive, gaze-contingent applications, and off-line diagnostic eye movement analysis.
