摘要

PROBLEM TO BE SOLVED: To provide a technique capable of continuously monitoring one's emotional level over a long period of time. A method of deriving a subject's mental state is to receive a biosignal from the subject, to calculate the statistical variation of each of at least two physiological parameters derived from the biosignal, and at least two. Obtaining the excitement level of a subject based on the calculated values of each statistical variation of physiological parameters, and deriving a time-region heart rate variability signal from a biosignal to calculate at least two heart rate variability parameters. It includes finding the subject's emotional value level based on the calculated values of at least two heart rate variability parameters, and deriving the mental state from the excitement level and the emotional value level.
