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.

ITU GazeTracker in the wild

Came across these two Youtube videos from students out there using the ITU GazeTracker in their HCI projects. By now the software has been downloaded 3000 times and the forum has seen close to three hundred posts. It's been a good start, better yet, a new version is in the makings. It offers a complete network API for third party applications, improved tracking performance, better camera control and a number of bugfixes (thanks for your feedback). It will be released when it's ready.

Thanks for posting the videos!
