Download a demo of my work on Head Pose and Eye Gaze Estimation here and run it on your own PC or Laptop using a webcam.

Tested on windows 98/2000/XP/vista. Use a webcam in front of you, almost at the eye level. No special conditions in terms of lighting are needed, as long as no heavy shadows appear. To start, face the web-camera frontally.
OR take a look at some videos of my work here

You can download the HPEG (Head Pose & Eye Gaze dataset), created in our laboratory. The dataset consists of two sessions: one just head pose of people moving freely their heads, and one combining both cues (Head Pose and Eye Gaze). It was recorded in indoors conditions, with a complex background and intense human action taking place in some of the sequences. For more details, please, read the paper found in this pdf file. The dataset can be freely downloaded and used for research reasons, and provided that any work done with the dataset should cite the work in this link
