Swedish company Tobii is about to release its MyTobii P10, a PC that can be controlled by tracking your eye movements using its own proprietary hardware and software. Follow a calibrating dot on the screen with your eyes for 30 seconds, and that's all it's necessary to make it so you can control this PC without touching it at all. The remarkable thing is, the company has figured out how to make this work in almost any lighting conditions, and even if you wear glasses.
This technology is not just for people who want to sit motionless for hours on end, it could prove to be a crucial technology for those less fortunate people with disabilities. An added convenience is its ability to mount to a desk, bed or wheelchair. Unfortunately, the first version of this PC will cost $17,000. But then, if you can't move your arms, legs, or anything else, that would probably be money well spent.
