This study introduced the development of a ‘low-cost eye-tracking device’ using a common web camera, an infra-red light, and PC. Two experiments were conducted to validate the utility of the eye-tracking device. In experiment 1, using a 25 fixation point display and an artificial face, the spatial resolution of the device was examined. In experiment 2, manipulating the presence/absence of the change-cue, we tried to replicate the change-blindness experiment by Levin & Simons(1997), and examined the eye-movement patterns for each condition. As results, it was observed that the number of fixation points in the change-cue condition were 92% higher, and the maximum fixation-dwelling time were 58% shorter than those in the no-cue condition. Finally, limitations and future developments of a low-cost eye-tracking device were discussed.
