Velichkovsky B.B., Rumyantsev М.А., Morozov М.А. New approach to solution of Midas Touch Problem: Identification of visual commands via extraction of focal fixations The Moscow University Psychology Bulletin, 3, 33-45
Reliable identification of intentional visual commands is a major problem in the development of eye-movements based user interfaces. This work suggests that the presence of focal visual fixations is indicative of visual commands. Two experiments are described which assessed the effectiveness of this approach in a simple gaze-control interface. Identification accuracy was shown to match that of the commonly used dwell time method. Using focal fixations led to less visual fatigue and higher speed of work. Perspectives of using focal fixations for identification of visual commands in various kinds of eye-movements based interfaces are discussed.
