ITU Gaze Tracker: Low-cost gaze interaction: ready to deliver the promises (San Agustin, J et al., 2009)

The research paper on the ITU Gaze Tracker that Javier San Agustin presented at CHI09 is now available at the ACM website. It evaluates a previous version of the gaze tracker in two tasks, target acquisition and eye typing in comparison with mouse, SMI IViewX RED and the Tobii 1750.

Abstract
"Eye movements are the only means of communication for some severely disabled people. However, the high prices of commercial eye tracking systems limit the access to this technology. In this pilot study we compare the performance of a low-cost, web cam-based gaze tracker that we have developed with two commercial trackers in two different tasks: target acquisition and eye typing. From analyses on throughput, words per minute and error rates we conclude that a low-cost solution can be as efficient as expensive commercial systems."
