PROBLEM TO BE SOLVED: To overcome a drawback that a traffic accident occurs when a driver of a vehicle dozes during driving.SOLUTION: When a driver is driving, if the driver is about to doze or dozes, an eye-camera of a line-of-sight tracking sensor unit is used to observe the movement of the driver's pupils or upper eyelids.
