Because we think that "Kansei" will be express in man's unconscious reaction. In this research, the hardware of "chest movement measurement tool" was manufactured using the mechanism of an optical mouse. And the pilot experiment has finished. Development of the analysis system for hypothesis testing has needed in next experimenting. The processing method of Physiological index data was built in this report.
