PROBLEM TO BE SOLVED: To enable to obtain quantitative data of an organism at high speed. SOLUTION: For time-series biological signals such as electroencephalogram, pulse wave, electrocariogram, electromyogram, expired gas or the like, a band which partly contains a high frequency band as a biological signal is extracted, a chaos characteristic is estimated by chaos analysis of calculating either a Lyapunov exponent or a correlation dimension, and emotional information of an organism is evaluated by the numerical information from the result. |
