Gaze Tracker: Low-cost interaction ready to deliver the promises

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.
