Abstract
A gaze tracking system captures images of a vehicle operator's face using an image sensor device positioned within a vehicle. The gaze tracking system may be detect facial features from each image and track the position of facial features over time. The gaze tracking system may use the detected facial features to track the vehicle operator's head pose and gaze direction. The images may be captured and analyzed in near-real time. By tracking movement of the driver's head and eyes over time, the gaze analysis system may predict or estimate head position and/or gaze direction when one or more facial features are not detectable. The gaze tracking system may generate a report regarding the vehicle operator's gaze distribution. The report may be saved to memory and may be graphically displayed at a screen.
