Measurement of Driver´s Consciousness by Image Processing -A Method for Presuming Driver´s Drowsiness by Eye-Blinks coping with Individual Differences -

Nowadays, driving support systems, such as car navigation systems, are getting common, and they support drivers in several aspects. It is important for driving support systems to detect status of driver´s consciousness. Particularly, detecting driver´s drowsiness could prevent drivers from collisions caused by drowsy driving. In this paper, we discuss a system and a method for detecting driver´s drowsiness, which use a property of blinks waveforms that driver´s eye-closing time is strongly connected to their drowsiness. Moreover, our system detects the drowsiness robustly for individual differences by using three factors extracted from the individual blink waveform.
