DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a psychological evaluation device, and more particularly, to a psychological evaluation device for evaluating compatibility between users based on the emotional tendency of the users and the similarity of emotional reactions.

[0002]

2. Description of the Related Art Conventionally, the degree of compatibility between appraisers (users) has been evaluated by a method called a questionnaire method.
The questionnaire method is based on a questionnaire in which questions such as values, views of life, and a sense of money appear in the answer are shown to the evaluator, and the answer to each item of the evaluator is set in advance. This method assigns a certain weighted score, defines a distance measure between the appraisers based on the proximity of the total score, and evaluates the compatibility between the appraisers.

[0003]

However, in the question paper method, since the question items are given in sentences, the evaluated person can easily guess the contents to be evaluated. For this reason, there was a problem that the answer was easy to be arbitrary and that a lie could be written. In addition, there is a problem that the accuracy of evaluation is low in the method of comparing the total points.

[0004] The present invention has been made to solve the above problems, and an object of the present invention is to provide a psychological evaluation device capable of obtaining a high evaluation accuracy without the arbitrariness of the evaluated person (user). It is to provide.

[0005]

According to the present invention, there is provided a psychological evaluation apparatus comprising: a state accumulating unit; a presenting unit; a selecting unit;
It has a code string storage means and a calculation means. The situation accumulation means accumulates a plurality of situations, each having a code indicating a rating item, and having similar meanings linked in the direction of elapse of time. The presenting means presents a situation having the code selected by the selecting means. The selection means selects one of the codes corresponding to the situation linked to the situation presented by the presentation means in accordance with the operation of the user. The code string storing means sequentially stores the codes selected by the selecting means as a code string for each user. The calculating means calculates a correlation value between the code strings accumulated by the code string accumulating means.

Preferably, the situation is a video. Preferably, the situation is audio.

In general, when a person is presented with a highly story-like content by reading a video, a novel or a story, it becomes difficult to consciously control his / her own emotion. In the psychological evaluation device, the status accumulating unit is linked to a status having a similar meaning, and the linked status is sequentially presented by the presentation unit. Therefore, it is possible to present to the user a situation as a rating stimulus with a high storytability and in which empathy is more likely to occur. This prevents the user from being arbitrary when selecting the next situation.

Further, codes corresponding to the selected situation are sequentially stored as code strings in the code string storage means. This is performed for each user.

Here, attention is paid to two specific users.
After the two persons have experienced a series of situations, the correlation value between the code strings accumulated for each person is calculated by the calculating means. The greater the correlation value between the two code strings, the more similar the emotional tendencies of the two are determined.

[0010] Further, without specifying the target person, all the users are targeted by using the emotional tendency as a scale.
Such as romantic or aggressive groups,
It can be divided into several groups.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. In the drawings, the same or corresponding portions have the same reference characters allotted, and description thereof will not be repeated.

FIG. 1 is a block diagram showing a configuration of a psychological evaluation device according to an embodiment of the present invention. Referring to FIG. 1, the psychological evaluation device includes a video storage device 1, a video content presentation device 2, a code selection device 3, a selected code sequence storage device 4, and a code sequence correlation calculation device 5.

The video storage device 1 stores video contents. The video content includes a plurality of sub stories. Each of the plurality of substory is provided with a code corresponding to a rating item such as a sense of value, a view of life, a sense of money, and the like. In each of the plurality of sub-stories, those having similar meanings are linked in a direction in which time elapses. In other words, when the linked sub-story is sequentially traced in the direction in which time elapses, the story has a series of flows. Therefore, it is possible to provide a user with an image as a stimulus for evaluation, which is highly story-like and in which empathy is more likely to occur. This prevents the user from being arbitrary when selecting the next situation. In addition, a branch point is provided in each of the plurality of sub stories. At the branch point, the user USR is requested to select the next substory. Here, a number is given to each of the linked sub-story and this number is displayed.

The video content presentation device 2 is a screen, and displays a substory selected by the user USR based on his / her own preference or judgment based on certain criteria as described later.

The code selection device 3 stores a code corresponding to the substory selected by the user USR in response to a selection request at each branch point in the substory.
And outputs it to the selected code string storage device 4. The user USR answers the selection request with a number.

The selected code string storage device 4 stores the code input from the code selection device 3 together with the order information by the user U.
It is stored as a code string for each SR.

The code string correlation calculator 5 calculates a correlation value between code strings stored in the selected code string storage 4.

Next, the operation of the psychological evaluation device configured as described above will be described with reference to FIG. Here, a case in which the compatibility between the user A and the user B is evaluated will be described as an example.

Each of a plurality of sub-storyes includes a1-a3, b1-b3, c1-c3, d1-d3, respectively.
The code of e1-e3 is given. Where a,
b, c, d, and e are the five elements of the code set, respectively, and 1-n represents the order of each branch point.

The video of the first substory from the video storage device 1 is displayed on the screen. At the branch point P1 in the first substory, a video requesting selection of the next substory is displayed. In contrast, user A
Selects the next substory based on their own preferences and certain criteria. The code a1 corresponding to the selected substory is sent to the video storage device 4, and the substory corresponding to the code a1 is displayed on the screen. The code a1 is stored in the selected code string storage device 4
Also sent to The selected code string storage device 4 stores the code a1 as a code string element for the user A.

At a branch point P2 in the next substory, an image requesting selection of the next substory is displayed. On the other hand, the user A selects the next substory based on his / her own preference or judgment based on certain criteria. Code a2 corresponding to the selected substory
Is sent to the video storage device 4, and the substory corresponding to the code a2 is displayed on the screen. The code a2 is also sent to the selected code string storage device 4. The selected code string storage device 4 stores the code a2 as a code string element for the user A.

Hereinafter, the same operation is performed at branch points P3 and P4 until the end of a series of stories.

As a result, the selected code string storage device 4
The code string (a1, a2, d3) of the user A is stored. Similarly, for user B, branch points P1, P12,
The code string (c1, b) is selected according to the selection result in P13.
2) is accumulated.

Next, in the code string correlation calculator 5,
The compatibility between the user A and the user B is obtained as follows.

First, the code string (a1, a2,
d3) is converted into a vector whose order is the number of all element codes. At that time, the value of the element is the number of each element. That is, the vector of the user A is (2, 0, 0, 1, 0). This is because element code a is twice, b is 0, c is 0
Times, d indicates once and e indicates 0 times. Further, the number of elements is normalized to a vector having a weight. That is, the normalized vector of the user A is
(2/3, 0, 0, 1/3, 0). Similarly,
The normalized vector of the user B is (0, 1/2, 1/2,
0,0). That is, the normalized vector is (C ＾
1, C ＾ 2, C ＾ 3, C ＾ 4, C ＾ 5). Here, C ＾ i (i = 1−5) is as shown in Expression 1.

[0026]

(Equation 1)

Here, N represents the number of branch points until the end of the story, Cij represents the presence / absence of selection of code j at branch point i, and its value is 0 or 1.

The calculation of the correlation value between the normalized vector of the user A and the normalized vector of the user B is performed by calculating the inner product of ordinary vectors.

The correlation value (-1.0 to +1.0) expressed in% is defined as the compatibility between the user A and the user B. It is determined that the greater the degree of compatibility, the more similar the emotional tendency is.

As described above, the psychological evaluation device according to the present embodiment includes a video storage device 1, a video content presentation device 2, a code selection device 3, and a selected code sequence storage device 4.
And the code string correlation calculation device 5, it is possible to obtain high evaluation accuracy without user's arbitraryness. Therefore, by using this psychological evaluation device, it becomes possible to prevent a problem of divorce or human disagreement due to personality mismatch or difference in values with a high probability.

In this case, the evaluation target is the compatibility degree between the user A and the user B. However, without specifying the target person, the evaluation is performed on all the users by using the emotional tendency as a scale. , Romantic groups and aggressive groups.

In addition, the user USR responds to the selection request at the branch point by a number,
The sub-story can be automatically selected by the code selection device 3 according to the magnitude of the output from a sensor such as an electroencephalograph attached to the SR.

Although the image is presented to the user as the evaluation stimulus here, the evaluation stimulus can be presented by voice such as reading a novel or a story.
