Research on the psychosomatic state transition of a driver based on a changing state hypothesis

The purpose of this research is to propose a methodology for predicting psychosomatic state transition of a driver by using the changing state hypothesis of a driver. A changing state hypothesis deals with change of the autonomic nerve system and homeostatic function. And the psychosomatic state is classified into four “Excitement term, Coexistence term, Attenuation term, Recuperation term”. In this paper, the bio-signals were investigated when the driving posture was changed in car driving. And the psychosomatic state evaluation of the driver based on the changing state hypothesis was carried out. As a result, it was clarified that the psychosomatic state estimation of a driver was possible to estimate using the changing state hypothesis. In addition, a usability of quantitative estimation of psychosomatic state that authors proposed is shown.
