Technical Field

The present invention relates to an unpleasant state determination device that determines an unpleasant state of a user based on biometric information of the user.

Background

Conventionally, there is provided a technique for determining the emotion of a user based on biometric information. Such a device using emotion determination technology is disclosed in patent document 1, for example. Patent document 1 discloses an unpleasant state determination device for determining a stress state of a user based on electroencephalogram data and pulse data.

Disclosure of Invention

Problems to be solved by the invention

The above-described conventional unpleasant state determination device determines the stress state of the user using electroencephalogram data and pulse data, and therefore, it is necessary to acquire these 2 pieces of data at the same time. In this case, the time required to acquire the pulse data is longer than the time required to acquire the electroencephalogram data. Therefore, the conventional unpleasantness determination device described above solves this problem by delaying the acquisition timing of the electroencephalogram data.

However, as described above, the conventional unpleasant state determination device described above takes into consideration the delay time in acquiring the biological information, but does not take into consideration individual differences in delay time and reaction intensity until the biological information appears as a reaction to the stimulus to the user.

The present invention has been made to solve the above-described problems, and an object thereof is to provide an unpleasant state determination device capable of improving the accuracy of determination of an unpleasant state for a user.

Means for solving the problems

The unpleasant state determination device of the present invention includes: an action detection unit that detects action information relating to an action of the user, which is preset for each category of the unpleasantness cause, on the basis of action information relating to an action corresponding to the unpleasantness cause of the user; an unpleasantness period estimation unit that acquires an estimation condition of an unpleasantness period of the user corresponding to the action information detected by the action detection unit and estimates the unpleasantness period using history information corresponding to the estimation condition; an unpleasantness estimator that estimates an unpleasantness state of a user based on a plurality of pieces of biometric information of the user; an unpleasantness estimator learning unit that estimates reaction times of the plurality of pieces of biological information for the unpleasantness cause based on the unpleasantness period estimated by the unpleasantness period estimation unit, and synchronizes input timings of the plurality of pieces of biological information to the unpleasantness estimator based on the unpleasantness period and the reaction times; and an unpleasantness determination unit that determines an unpleasantness state of the user based on an estimation result of the unpleasantness estimator when the behavior detection unit detects the behavior information.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, the accuracy of determining the unpleasantness of the user can be improved.
