Abstract
A system for determining a vehicle operator's level of fatigue comprises a camera for detecting at least the vehicle operator's eyes; an onboard vehicle detector for detecting at least one of vehicle speed, location, activity, acceleration, deceleration, or steering wheel rotation; and a processor which receives information detected by the camera and the onboard vehicle detector and calculates a real-time operator fatigue score based on the received data. The operator fatigue score may further be based on an operator's time of shift, type of vehicle, and current and previous tasks.
