A Light on Physiological Sensors for Efficient Driver Drowsiness Detection System
Résumé
The significant advance in bio-sensor technologies hold promise to monitor human physiological
signals in real time. In the context of public safety, such technology knows notable research investigations to
objectively detect early stage of driver drowsiness that impairs driver performance under various conditions.
Seeking for low-cost, compact yet reliable sensing technology that can provide a solution to drowsy state
problem is challenging. While some enduring solutions have been available as prototypes for a while, many of
these technologies are now in the development, validation testing, or even commercialization stages. The
contribution of this paper is to assess current progress in the development of bio-sensors based driver drowsiness
detection technologies and study their fundamental specifications to achieve accuracy requirements. Existing
market and research products are then ranked following the discussed specifications. The finding of this work is
to provide a methodology to facilitate making the appropriate hardware choice to implement efficient yet lowcost
drowsiness detection system using existing market physiological based sensors,
