  Driver drowsiness problem is considered as one of the most important reasons
that increases road accidents number. We propose in this paper a new approach
for realtime driver drowsiness in order to prevent road accidents. The system
uses a smart video camera that takes drivers faces images and supervises the
eye blink (open and close) state and head posture to detect the different
drowsiness states. Face and eye detection are done by Viola and Jones
technique.
