Abstract
This research deals with construction of evaluation method for driver's strain usng facial temperature. We have already confirmed possibility of evaluation of driver's strain using facial temperature. However the response speed of facial temperature is not investigated. Then, we examine respons speed of facial temperature. We experiment that subject was heard the loud crash sound and was strain. As a result, response speed of facial temperature was shown. And the effectiveness when the facial temperature was applied to the driver support system was shown.
