The Estimation of Driver's Arousal State (1)~Based on Facial Expression and Physiological Indices

Event: JSAE Spring Meeting
The goal of this research is to develop a method to assess the arousal states using facial images of drivers. In this paper, we propose new criteria for assessment of driver's arousal states using facial expression to characterize the battle against drowsiness. Multi-dimensional physiological indices (i.e., blink categories, electrodermal activity, EEG alpha wave, respiration, heart rate variability) were analyzed and compared to the scores obtained by the proposed method.
