Abstract: There are different problems with eye-tracking systems such as users' head movements, multi-user compatibility and environment's light variation that reduce the accurately of these systems. The current research investigates the performance of using classifiers in the calibration stage of an infrared eye-tracking system on 10 subjects several times. The results show that classifiers can reduce the mentioned problems and improve the operation of the system to recognize the eye-gaze direction more accurately and furthermore give the system the ability to adjust with various interferential factors that will be interesting and important for a number of applications requiring human computer interfaces.
Keywords: human-computer interface; HCI; eye tracking technology; classification; infrared tracking; biomedical engineering; eye gaze direction.
