The use of Eye Tracking technology has the potential to augment current teaching, evaluation, and research methods in simulated settings by using this quantitative, objective data to better understand why an individual performed as he or she did on a simulated or naturalistic task. Eye Tracking is used in various areas, mostly in the medical and ophthalmic research, commercial applications to determine the usability of websites and printed materials, in the creation of various simulators and systems of augmented reality, in modern video surveillance, and so on. Eye Trackers are also actively used in specialized medical centers to create a system of communication with patients who have partially or totally lost their motor function, those suffering from serious lesions of the musculoskeletal system, or speech disorders.
