WoW gaze interaction: Necessary? Probably not. Cool? Yes.

We tested some eye-tracking software like this at CeBIT this year but this takes the concept to a whole other level. It’s basically a system for tracking your gaze that has been retrofitted to work with WoW. Why? I guess it could let the handicapped or, sadly, the catastrophically lazy, play the game without having to touch a keyboard. My money is on the former.

Eye-gaze systems bounce infrared light from LEDs at the bottom of a computer monitor and track a person’s eye movements using stereo infrared cameras. This setup can calculate where on a screen the user is looking with an accuracy of about 5 mm.
