By using low cost webcams such as the Lifecam VX-100 or similar this person from Argentina have produced an eye tracker capable of running the Gaze Talk interface. The total cost for the eye tracker hardware is US$ 40-50. The software runs on a typical desktop or laptop computer using the OpenCV based image processing algorithms.
"My goal is to develop an open source system that enables people with severe motor disabilities to interact with the computer using their eye movements."
The project is running for another three weeks and the outcome will be very interesting. Check out the development blog at http://www.eyegazetracking.com/
