Abstract
A system for monitoring a driver's attention to driving a vehicle includes a camera having a field of view wherein a driver's face is positioned in the field of view of the camera. The system also includes a gaze and facial pose determiner coupled to the camera which receives signals corresponding to images of the driver's face for analysis. The gaze and facial pose determiner determines whether the gaze and facial pose of the driver are oriented in a forward direction of travel of the vehicle. The system also includes an alarm responsive to the gaze and facial pose determiner for advising the driver that his gaze and facial pose are not oriented in the forward direction of travel of the vehicle.
