In order to achieve safe, comfortable, and healthy life, products and services are needed to be developed on the basis of an understanding of human psychophysiological characteristics. To this end, I am engaged in research to develop technology for assessing mental state of human by mathematically analyzing physiological signals. Heart rate variability is one of the few physiological signals that can be measured stably without bothering ones daily life activity. We have done daily life experiments to clarify the relationship between autonomic nervous system physiological signals such as heart rate variability and mental state. Based on the daily life experiment, we have developed technologies such as ‘personal adaptive method to assess mental tension during daily life using heart rate variability’, ‘detecting “Hiyari-Hat” (“Startled”,“Near-Miss”) state using physiological signals’, and so on. In this presentation, I present about these technologies and discuss about the possibility and limitation for the future study.
