Gentex’s driver monitoring system tracks driver head pose, eye gaze, and other metrics to determine distraction, drowsiness, sudden sickness, and return of manual control in semi-autonomous vehicles. The system can be easily expanded to include 2D and 3D cabin monitoring for detecting passengers, behavior, objects, and even presence of life. Additionally, machine olfaction sensors provide a digital sense of smell for detecting airborne chemicals and particulates, helping keep passengers safe and vehicles up and running.
