Paper Abstract

In this paper a new data processing and calibration method for an eye-tracking device is described. The eye-tracking device is created both by the technology of head mounted display and remote type set-up. The computer analysis of various types; is suggested to obtain the characteristics of image type eye-tracking device. We use fuzzy analysis method to distinguish the position of the pupil and calculate the coordinates of them. With one video CCD camera and frame grabber analyzing a series of images of human pupil during gazing the screen, an auto-calibration algorithm is used to obtain the direction of eye gaze in real time. The computers will provide the functions according to the location where the eye gaze at exceeding 0.5 second. The availability of multipurpose measurement of this eye-tracking system with very simple equipment will be reconfirmed for the advanced research.
