Kansei’s Physiological Measurement and Its application (1)

Recent behavioral medicine studies have revealed that various human secretory substances change according to mental states. These substances, the hormones and immune substances show transient increase against mental stress. Therefore it is frequently introduced as an objective index (biomarker) of mental stress. Especially the biomarker which is detectable by human saliva is expected to be a new and practical stress measurement as it can be sampled in less stressful and noninvasive manner unlike blood and urine. In this chapter, the biomarker research, its background, methodology, experiment, and numerical simulation approaches are introduced. Also in the end, it is stated as a possible approach towards a measurement of Kansei.
