Abstract
This study investigates brain activity related to drivers' anxiety induced by external situations during watching driving video using electroencephalography (EEG). We conducted a spectral analysis of 4 frequency bands, including theta, alpha, beta, and gamma bands, of frontal brain oscillations known to be involved in emotion recognition. Furthermore, we calculated frontal asymmetry and beta/alpha ratio with respect to the valence-arousal domain. We confirmed that driver's perspective video could induce anxiety in the viewers and found three frontal EEG features pronounced in anxious situations: 1) smaller alpha power reflecting more cognitive control; 2) right dominance of theta and beta oscillations; and 3) greater difference between beta and alpha. These EEG features may provide a basis for developing technology to monitor drivers' emotional states in smart cars.
