Abstract
A system for monitoring an alertness level of an occupant of a vehicle includes a first sensor operable to detect an event exterior to the vehicle. A second imager is operable to capture an image of the occupant. A controller is in electrical communication with the first sensor and the second sensor. The controller is configured to determine a target direction aligning with a region of the event. The controller is further configured to determine a viewing direction of the occupant based on the image. The controller is further configured to compare the target direction to the viewing direction. The controller is further configured to determine the alertness level of the driver based on the comparison of the target direction to the viewing direction.
