ABSTRACT:
A method of rectifying drowsiness of a vehicle driver includes capturing a sequence of images of the driver. It is determined, based in the images, whether a head of the driver is tilting away from a vertical orientation in a substantially lateral direction toward a shoulder of the driver. The driver is awakened with sensory stimuli only if it is determined that the head of the driver is tilting away from a vertical orientation in a substantially lateral direction toward a shoulder of the driver.
