System immersion of a driving simulator affects the oscillatory brain activity

Abstract

The technological properties of a system delivering simulation experience are a cru- cial dimension of immersion. To create a sense of presence and reproduce drivers behaviour as realistically as possible, we need reliable driving simulators that allow drivers to become highly immersed. This study investigates the impact of a system immersion of a driving simulator on the drivers’ brain activity while operating a con- ditionally automated vehicle. Nineteen participants drove approximately 40 minutes while their brain activity was recorded using electroencephalography (EEG). We found a significant effect of the system immersion in the occipital and parietal areas, prima- rily in the high-Beta bandwidth. No effect was found in the Theta, Alpha, and low-Beta bandwidths. These findings suggest that the system immersion might influence the drivers’ physiological arousal, consequently influencing their cognitive and emotional processes.
