Unlike most of the devices and gadgets on the market designed to keep you awake while driving that monitor your head movements and eyes. The Anti Sleep Pilot attached to your dashboard and monitors your fatigue levels.
It does this by using reaction times from tests which maintain alertness, among many other inputs. It then works on the basis of these personal calculations to recommend that you take a break when you are about to hit a critical driving fatigue level, and thus prevents accidents.
Currently the Anti Sleep Pilot is available in Denmark but will hopefully making an appearance worldwide shortly.
