Measurement of a Driver´s Mental State Using a 4K Driving Simulator

We have been researching a method that can induce a driver to drive more safely and more comfortably by grasping the mental state of the driver. For this purpose, we developed a 4K DS system to more realistically create the sense of driving through a landscape. We analyzed the gazing point distribution, oxygen concentration in the brain, pulse rate, skin potential, and the surface temperature of the face while driving. The subjects included 11 students from our university, aged 20~22 years old, who had driver´s licenses. They simulated driving the full 120-km length of a road over the course of one hour. In the results, characteristic changes were seen in all parameters in every subject. In the future, we will consider the correlations among data in a more detailed analysis to attempt to grasp the mental state of the driver.
