Abstract

This research examined the relevance of the face skin temperature change and the amount change of face blood flows by the degree fall of transient awakening of a driver. First, the data of face expression evaluation, alpha wave power, and LF/HF were compared with the data of precedence research on the basis of nasal part skin temperature. The data of face expression evaluation, alpha wave power, and LF/HF was mostly in agreement. Next, comparison of the amount of face blood flows and nasal part skin temperature was performed using the proved data. A result -- the amount of face blood flows, and nasal part skin temperature every subject some although there was a difference, it detected negative high correlation This was the result of differing from the conventional view. Since the result was summarized this time using the hypothesis of the relation nature of the amount of face blood flows, and nasal part skin temperature.
