Abstract

Disclosed is a psychological state estimation device for estimating the psychological state of a subject. A psychological state estimation device for estimating the psychological state of a subject includes bioinformation acquiring means for acquiring bioinformation of the subject, perception response acquiring means for acquiring the perception response of the subject to an external event, influence degree acquiring means for acquiring the degree of influence on a change in the psychological state of the subject on the basis of the acquired perception response, and estimating means for estimating the psychological state of the subject on the basis of the bioinformation and the degree of influence on the change in the psychological state.

Claims

1. A psychological state estimation device for estimating the psychological state of a subject,

perception response acquiring means for acquiring the perception response of the subject to an external event;

and

estimating means for estimating the psychological state of the subject on the basis of the perception response acquired by the perception response acquiring means.

2. The psychological state estimation device according to claim 1, further comprising:

influence degree acquiring means for acquiring the degree of influence on a change in the psychological state of the subject on the basis of the perception response acquired by the perception response acquiring means,

wherein the estimating means estimates the psychological state of the subject on the basis of the degree of influence acquired by the influence degree acquiring means.

3. The psychological state estimation device according to claim 2,

wherein, when the perception response acquiring means finds that the subject shows a defensive response, the influence degree acquiring means increases the degree of influence on the change in the psychological state of the subject more than when the subject does not show the defensive response.

4. The psychological state estimation device according to claim 2, further comprising:

bioinformation acquiring means for acquiring bioinformation of the subject,

wherein the estimating means estimates the psychological state of the subject on the basis of the bioinformation acquired by the bioinformation acquiring means and the degree of influence acquired by the influence degree acquiring means.

5. The psychological state estimation device according to claim 2,

wherein the influence degree acquiring means sets the degree of influence on the change in the psychological state depending on the external event and a perception response coefficient depending on the perception response acquired by the perception response acquiring means, and acquires the degree of influence on the basis of the degree of influence on the change in the psychological state depending on the external event with the perception response coefficient.

6. The psychological state estimation device according to claim 3, further comprising:

bioinformation acquiring means for acquiring bioinformation of the subject,

wherein the estimating means estimates the psychological state of the subject on the basis of the bioinformation acquired by the bioinformation acquiring means and the degree of influence acquired by the influence degree acquiring means.

7. The psychological state estimation device according to claim 3,

wherein the influence degree acquiring means sets the degree of influence on the change in the psychological state depending on the external event and a perception response coefficient depending on the perception response acquired by the perception response acquiring means, and acquires the degree of influence on the basis of the degree of influence on the change in the psychological state depending on the external event with the perception response coefficient.

8. The psychological state estimation device according to claim 4,

wherein the influence degree acquiring means sets the degree of influence on the change in the psychological state depending on the external event and a perception response coefficient depending on the perception response acquired by the perception response acquiring means, and acquires the degree of influence on the basis of the degree of influence on the change in the psychological state depending on the external event with the perception response coefficient.
