We are developing a system for analyzing human driver alertness in mobile and stationary vehicles. It relies on optical flow, combined with color predicates to robustly track a person's head and facial features. We then determine what kind of activity the driver is performing. We currently classify rotation in all viewing directions, detect eye/mouth occlusion, detect eye blinking, and recover the 3D gaze of the eyes. We show results and discuss how this system can be used for monitoring driver alertness.
