Evaluation of a remote webcam-based eye tracker

Abstract

In this paper we assess the performance of an open-source gaze tracker in a remote (i.e. table-mounted) setup, and compare it with two other commercial eye trackers. An experiment with 5 subjects showed the open-source eye tracker to have a significantly higher level of accuracy than one of the commercial systems, Mirametrix S1, but also a higher error rate than the other commercial system, a Tobii T60. We conclude that the web-camera solution may be viable for people who need a substitute for the mouse input but cannot afford a commercial system.
