Impressive what can now be done with such precision with just a regular webcam. Previously special hardware like the Tobii eyetracker was required for this level of precision.

This is a neat trick, but the precision is gonna be horrid with that approach. And it'll be needed to be tuned a lot for each new user.
Special hardware has never been really needed. Just a camera close enough to the eye. IR leds and filters can be added for some convenience.
Only thing special about Tobii etc hardware is the pricetag.
