The Estimation of Driver's Arousal State (3)~Changes in Multi-Dimensional Physiological Indices
Published May 20, 2009 by Society of Automotive Engineers of Japan in Japan
Event: JSAE Spring Conference
The goal of this research is to develop a method to assess the arousal states using facial images of drivers. In the previous paper, we proposed new criteria for assessment of driver's arousal states using facial expression to characterize the battle against drowsiness. Obtaining a new data set of 15 volunteers, the relationship between facial scores and multi-dimensional physiological indices (i.e., blink parameters electrodermal activity, EEG alpha wave, respiration, heart rate variability) were studied.
