I was wondering if there is a way to achieve eye tracking-gaze aware with various ways inside VVVV? ( It can be done with the use of webcam? or does it need more advance hardware?) I did a research on eye-tracking and I found a lot of commercial products which are expensive but I’ve also found and some opensource software’s that achieved eye-tracking with a webcam.(ex. http://www.gazegroup.org/) and (http://eyewriter.org/)
What do you think about intel`s perceptual computing camera? Is the facial detection good enough to track the eyes?
Basically I want to track where the user sees in the screen and if he is looking on a specific element it would trigger an action on the screen.
