Tobii eye tracking systems enable you to efficiently obtain valid and reliable eye tracking research results, by being easy to use, unobtrusive, and highly accurate and precise. The Tobii Studio eye tracking software provides a comprehensive platform for recording, observation, analysis and visualization in heat maps and gaze plots.

"Students out at Brigham Young University in Utah have taken an interesting turn in the now-developing eye controlled PC wars (some war-so far it's two parties), and the turn will give Brigham Young a critical edge: namely, a 75 percent price cut. A while back we talked about the PCEye from Tobii, the system that allowed a Lenovo laptop to get controlled by a series of glances and blinks out at the CeBIT show. And then we later announced that it got priced, at a whopping $6900 per unit. This made an already bad situation in which the PCEye might have been useful significantly worse by making it almost inaccessible to those who could have used it."

"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."
