Abstract: A method for determining an Eyes-Off-The-Road (EOTR) condition exists includes capturing image data corresponding to a driver from a monocular camera device. A detection of whether the driver is wearing eye glasses based on the image data using an eye glasses classifier. When it is detected that the driver is wearing eye glasses, a driver face location is detected from the captured image data and it is determined whether the EOTR condition exists based on the driver face location using an EOTR classifier.

Abstract: A driver alert system includes a computer processor disposed in a vehicle. The computer processor is configured to receive driver attention data over a vehicle network during a driving event. The computer processor executes logic to process the driver attention data and evaluate the driver attention data for a triggering event. The system also includes a steering wheel unit disposed in the vehicle and lights that are integrated on a front windshield-facing surface of a steering wheel of the steering wheel unit. The lights are positioned at an angle to reflect light off of a front windshield of the vehicle. The system also includes a controller disposed in the steering wheel unit. The controller is communicatively coupled to the lights and the vehicle network. The controller receives a request from the computer processor to activate the lights when the triggering event has occurred.

Abstract: A method for detecting an eyes-off-the-road condition based on an estimated gaze direction of a driver of a vehicle includes monitoring facial feature points of the driver within image input data captured by an in-vehicle camera device. A location for each of a plurality of eye features for an eyeball of the driver is detected based on the monitored facial features. A head pose of the driver is estimated based on the monitored facial feature points. The gaze direction of the driver is estimated based on the detected location for each of the plurality of eye features and the estimated head pose.
