Cheng, D. and Vertegaal, R. An eye for an eye: a performance evaluation comparison of the LC technologies and Tobii eye trackers. In Proceedings of the 2004 Symposium on Eye Tracking Research & Applications (San Antonio, Texas, March 22 - 24, 2004). ETRA '04. ACM, New York, NY, 61-61, 2004.
Eye-tracking systems have been employed in many diverse fields, including psychology, cognitive science, disability rehabilitation
research, and human-computer-interaction (HCI). Although numerous studies have been conducted involving applications of eye tracking,
few studies have compared the actual eye-tracking systems themselves. We empirically evaluated the system characteristics of two
independent eye-tracking products using the following parameters: accuracy, reliability, robustness, ease of setup, ease of development,
API capabilities, and real-time performance as metrics. As well, we qualitatively evaluated the various analytical software tools and
features provided by each eye-tracker.
