Falling asleep while at the helm of a few tons of metal and plastic going 60 miles-per-hour doesn't end well, but there's little the modern car can do about it. If it, say, stopped itself suddenly it could become a hazard to other drivers. The Eyetracker system knows it's not on the car, though — it's on you to drive safe.
With that in mind, the German-based Eyetracker watches the driver's face for telltale signs of sleepiness, and issues a warning if it looks like you're about to doze off. The system uses two cameras to keep tabs on the spatial positioning of the pupil and the line of vision — which would waver if you're about to pass out. In other words, it makes sure your eyes are on the road.
What's really exciting here is how small and easy to install the system is, which could see it put to use in ways other than keeping drivers awake (a noble cause, to be sure). Despite the picture above, the Eyetracker doesn't need a laptop to function, and its control unit is the size of a matchbox. What's more, it can be installed in any car as it handles all of its own processing itself.
Beyond just the automobile world, the Eyetacker could aid in medical operations where being able to keep on eye on — well — an eye is essential, or even in video games, serving as a head-tracker that lets the player look around without the aid of a physical controller.
