Agustin, Javier San, Hansen, John Paulin, Hansen, Dan Witzner and Skovsgaard, Henrik (2009): Low-cost gaze pointing and EMG clicking. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3247-3252. Available online

Some severely disabled people are excluded from using gaze interaction because gaze trackers are usually expensive (above $10.000). In this paper we present a low-cost gaze pointer, which we have tested in combination with a desktop monitor and a wearable display. It is not as accurate as commercial gaze trackers, and walking while pointing with gaze on a wearable display turned out to be particularly difficult. However, in front of a desktop monitor it is precise enough to support communication. Supplemented with a commercial EMG switch it offers a complete hands-free, gaze-and-click control for less than $200.

We investigate if the gaze (point of regard) can control a remote vehicle driving on a racing track. Five different input devices (on-screen buttons, mouse-pointing low-cost webcam eye tracker and two commercial eye tracking systems) provide heading and speed control on the scene view transmitted from the moving robot. Gaze control was found to be similar to mouse control. This suggests that robots and wheelchairs may be controlled "hands-free" through gaze. Low precision gaze tracking and image transmission delays had noticeable effect on performance.

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, webcam-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.
