Through advanced research & development for about ten years at the University of Liège (ULg) in Belgium under the leadership of Professor Jacques G. Verly from its Department of Electrical Engineering and Computer Science, the ULg and its spin-off company Phasya have established themselves as world leaders in the development of innovative and validated solutions in the area of drowsiness (or somnolence) monitoring. This technology can, among others, prevent transportation accidents where the operator falls asleep while driving a car, truck, or train, steering a boat, flying an airplane, etc. Most people are surprised to learn that 30% of fatal accidents on highways are due to drivers falling asleep at the wheel!
