<p>PROBLEM TO BE SOLVED: To provide a technique for more accurately comprehending a biological state.SOLUTION: The present invention estimates a biological state, by using a predetermined central nervous system index value obtained from a central nervous system biological signal information and a predetermined peripheral nervous system index value obtained from a peripheral nervous system biological signal information, from a positional relationship between coordinate points on a coordinate system in which those indexes are set as coordinate axes. When performing state estimation of a person, a state of the person can be more accurately estimated by using both indexes as the present invention to have a configuration for determining the state of the person on a single coordinate system, so that each of variations of the indexes with respect to the state change of the person is emphasized, than using any one of indexes.</p> |
