Webcam-based eye tracking technology

Usually, eye tracking technology consists of an infrared camera, attached to the computer. However, using a simple RGB camera enables eye tracking to be done from every computer/laptop with a camera, thus increasing flexibility greatly.

This free white paper discusses the methodology and accuracy behind the technology. It also gives a validation example and indicates how to start using it in your own project.
