"Adding one to the list of things I've never thought of that are actually pretty cool, scientists at De Montfort University in the UK have developed a way to control WoW with your eyes. The system uses existing LED eye-tracking devices, and essentially the cursor just goes where you look. Looking offscreen in various directions can trigger different modes (for combat or travel, for instance). The intention behind this project is to help people with disabilities that prevent them from using traditional input devices. So far, judging by the video, the interface is not up to par with clicking or key-pressing, but I think it does have potential for situations where it's required. The research team hopes to begin trials next year.[via Wonderland]"^^<http://www.w3.org/2001/XMLSchema#string>
