Remote tracker and 6DOF using a webcam

The following video clips demonstrates a Masters thesis project from the AGH University of Science and Technology in Cracow, Poland. The method developed provides 6 degrees of freedom head tracking and 2D eye tracking using a simple, low resolution 640x480 webcam. Under the hood it's based on the Lucas-Kanade optical flow and POSIT. A great start as the head tracking seems relatively stable. Imagine it with IR illumination, a camera with slightly higher resolution and a narrow angle lens. And of course, pupil + glint tracking algorithms for calibrated gaze estimation.
