The driver's mental and physical condition is key to the safe operation of a vehicle. Fatigue due to sleep deprivation, monotony or long travel times, as well as distraction from cell phones or other secondary tasks while driving can negatively impact the driver's ability to perform the driving task. Driving the vehicle is not given the full attention it requires. The latest developments in highly automated driving are already putting the driver in a largely passive role that is often accompanied with monotony and reduced vigilance. Therefore, monitoring the mental and physical state of drivers will become even more important in the future to ensure that the driver remains able to reassume control of the vehicle from various levels of driving automation systems in critical situations. WIVW has many years' experience in instrument-based measurement of fatigue (by evaluating eyelid closure rates) as well as driver attentiveness and distraction with eye-tracking.
