Comparison of Thermal Stimulations to Reduce Drowsiness based on Correlation Analysis

The purpose of this study is to develop a system that inhibits driverâ?™s drowsiness depending on the autonomic nervous system activity. We have tested the system through several experiments. This study seeks to examine correlation between nasal skin temperature and driverâ?™s drowsiness by using cool stimulation and warm stimulation on their skin. As the result of experimentation, it showed that there is high correlation between nasal skin temperature and drowsiness. It is suggested that our method for controlling drowsiness is efficient.
