Block diagram showing the configuration of the love degree diagnosis system The flowchart which shows the procedure of the love degree diagnosis performed by the central processing unit

  FIG. 1 is a block diagram showing a configuration of a love degree diagnosis system 1 according to the present embodiment. This love degree diagnosis system 1 diagnoses a love degree based on a subject's brain wave, and includes an electroencephalogram sensor 10 and a love degree diagnosis apparatus 20. This system pays attention to the brain wave of the subject and diagnoses the degree of love of the subject with respect to the love target, and preferably uses the brain wave in a state where the love target is viewed. Here, the romance target person does not matter whether or not the subject already has a romance feeling for the person, and includes a wide range of other persons whose romance level is subject to diagnosis regardless of gender or the like. It may also include the subject himself, such as self-love (narcissist).

  The electroencephalogram sensor 10 is mainly composed of a detection unit 11 and a calculation unit 12. The detection unit 11 includes a pair of electrodes 11 a and 11 b, and the individual electrodes 11 a and 11 b are electrically connected to the calculation unit 12. The pair of electrodes 11 a and 11 b are mounted on the subject's head, thereby detecting an electrical signal emitted from the subject's head and outputting the detected signal to the calculation unit 12.

  Although the detection part 11 should just be provided with at least 1 electrode, the improvement of the detection accuracy of an electroencephalogram can be aimed at by providing a some electrode. When the detection unit 11 is configured by a pair of electrodes 11a and 11b as in the present embodiment, one electrode 11a is attached to the forehead via a hair band or the like, and the other electrode 11b is provided with a clip or the like, for example. It is attached to the earlobe. Since the electroencephalogram is a weak signal, the detected electrical signal contains electromyograms associated with movement and blinking and commercial frequency noise. There are many biological reactions in the signal detected through the forehead, but the signal detected through the earlobe tends not to contain an electroencephalogram component. Therefore, noise can be canceled by measuring the potential difference between the forehead with the electrodes 11a and 11b and the earlobe, so that the electroencephalogram can be accurately measured by the arithmetic unit 12 described later.

  The calculation unit 12 reads a digital signal obtained by subjecting the electrical signal from the detection unit 11 to A / D conversion at a predetermined period, and measures an electroencephalogram as a time-series digital signal. As the arithmetic unit 12, a microcomputer mainly composed of a CPU, a ROM, a RAM, and an I / O interface can be used.

  When determining that the electroencephalogram can be appropriately measured, the arithmetic unit 12 measures the electroencephalogram over a predetermined sampling period (for example, 15 seconds). In addition, the calculation unit 12 extracts a θ wave, an α wave, a β wave, and a γ wave based on the measured brain waves. Here, the θ wave, the α wave, the β wave, and the γ wave indicate waves of a predetermined frequency included in the brain wave, the θ wave is a frequency of 4 to 7 Hz, the α wave is a frequency of 8 to 12 Hz, and β The wave corresponds to a frequency of 13 to 30 Hz, and the γ wave corresponds to a frequency of 30 to 100 hz.

  The computing unit 12 extracts brain waves corresponding to each frequency using, for example, Fourier transform (fast Fourier transform or the like) that converts time information into frequency information. Here, the θ wave appears corresponding to sleepiness or deep meditation among human mental states or physiological states, and the α wave corresponds to a state of closed eyes or a relaxed state. It tends to appear. That is, by focusing on the θ wave or the α wave, it is possible to quantitatively evaluate the human relaxed state. Further, the β wave appears corresponding to the awakened state or the concentrated state, and the γ wave tends to appear corresponding to the concentrated state or the like. That is, by focusing on the β wave or γ wave, it is possible to quantitatively evaluate the human mental concentration state.

  Next, the calculating part 12 calculates the relaxation degree f1 and the concentration degree f2 based on each extracted wave. In addition, the calculation method of the relaxation degree f1 and the concentration degree f2 shown below shows the example, and as long as it calculates as a value which shows a test subject's mental relaxation or concentration quantitatively, the method is Any technique can be used.

  The degree of relaxation f1 is a value (for example, expressed as a percentage from 0 to 100) that quantitatively indicates the degree of mental relaxation of the subject. The higher this value, the lower the mental activity and the more relaxed state. Conversely, the lower this value, the higher the mental activity. The degree of relaxation f1 is calculated based on a θ wave or an α wave having a correlation with the relaxed state of the subject among the extracted waves.

  Specifically, the calculation unit 12 calculates an average value (hereinafter referred to as “reference average value”) of the frequency of the α wave measured in the initial period (for example, 0 second to 4 seconds) of the sampling period, and calculates this average value. The degree of relaxation is defined as f1 = 50%. In addition, in the remaining period (4 seconds to 15 seconds) of the sampling period, the calculation unit 12 updates the average value of the frequency of the α wave every time the electroencephalogram is measured, and compares the updated average value with the reference average value. The degree of relaxation f1 is calculated as an arbitrary value from 0% to 100%.

  Note that the relaxation degree f1 may be calculated using a θ wave having a correlation with the relaxed state of the subject instead of the α wave. The degree of relaxation f1 may be calculated based on each of the α wave and the θ wave, and may be obtained by an average value of individual values, or may be corrected / adjusted by using the other value as a main value. May be.

  On the other hand, the degree of concentration f2 is a value that quantitatively indicates the degree of mental concentration of the subject. The higher the value, the more concentrated the spirit, and vice versa. Show that you are not mentally focused. This concentration degree f2 is calculated based on a β wave or a γ wave having a correlation with the concentration state of the subject.

  Specifically, the calculation unit 12 calculates an average value (hereinafter referred to as “reference average value”) of the frequency of the β wave measured in the initial period (for example, 0 second to 4 seconds) of the sampling period, and calculates the average value. The concentration degree is defined as f2 = 50%. In addition, in the remaining period (4 seconds to 15 seconds) of the sampling period, the calculation unit 12 updates the average value of the frequency of the β wave every time the electroencephalogram is measured, and compares the updated average value with the reference average value. The concentration degree f2 is calculated as an arbitrary value from 0% to 100%.

  The degree of concentration f2 may be calculated using a γ wave having a correlation with the concentration state of the subject instead of the β wave. The concentration degree f2 may be calculated based on each of the β wave and the γ wave, and may be obtained by an average value of individual values, or may be corrected / adjusted by using the other value as one of the main values. May be.

  The calculated degree of relaxation f1 and degree of concentration f2 are output to the love degree diagnostic apparatus 20. As described above, the calculation unit 12 outputs a signal indicating the state (hereinafter referred to as “measurement state signal”) to the love degree diagnosis device 20 while measuring the electroencephalogram over the sampling period. Thus, the measurement period of the electroencephalogram can be notified.

  The love level diagnosis device 20 diagnoses the degree of love of the subject with respect to the love target person based on the relaxation degree f1 and the concentration degree f2 output from the electroencephalogram sensor 10. As the love level diagnostic device 20, various information devices such as a computer, a smartphone, a mobile phone, and a portable information terminal can be used.

  This love degree diagnostic apparatus 20 is mainly composed of an input unit 21, a memory 22, an operation display unit 23, and a central processing unit 24, and these elements are connected to each other via a bus.

  The input unit 21 is an interface for transmitting and receiving signals to and from the electroencephalogram sensor 10. By this input unit 21, information on the α wave, β wave, θ wave, and γ wave included in the brain wave of the subject, specifically, the degree of relaxation f1 and the degree of concentration f2 are acquired. The connection between the input unit 21 and the electroencephalogram sensor 10 may be made via a network such as a LAN, in addition to using a signal communication cable.

  The memory 22 stores a control program, information on processing functions of the apparatus, and the like, and temporarily stores data read from the input unit 21.

  The operation display unit 23 can use, for example, a touch panel that can display various information on the display, and can perform an input operation in accordance with the information displayed on the display. For example, the user operates a predetermined icon or setting screen displayed on the operation display unit 23 to instruct the central processing unit 24 to start a love degree diagnosis, or makes various settings to the central processing unit 24. Can be directed. Further, the operation display unit 23 can display the diagnosis result of the love degree diagnosis by being controlled by the central processing unit 24.

  The central processing unit 24 performs various calculations related to the love degree diagnosis according to the control program read from the memory 22. Specifically, the central processing unit 24 calculates an evaluation value E for quantitatively evaluating the subject's love feeling based on the degree of relaxation f1 and the degree of concentration f2, and the degree of love is calculated based on the evaluation value E. Diagnose.

  The present applicant measured and analyzed the brain waves in the natural state of the subjects and the brain waves in a state where various persons were visually observed, for 1000 subjects. According to this analysis result, it has been found that the greater the positive love feelings for the person who is viewed, the greater the degree of relaxation f1 and the degree of concentration f2 tend to show. Therefore, based on such knowledge, the central processing unit 24 calculates the evaluation value E based on the following equation.

(Formula 1)
E = A ・ f1 + B ・ f2

  Here, A is a first weighting factor corresponding to the relaxation degree f1, and B is a second weighting factor corresponding to the concentration degree f2. That is, the evaluation value E is basically obtained as a value corresponding to the sum of the degree of relaxation f1 and the degree of concentration f2, and the larger the value, the greater the favorable romantic feeling. In the present embodiment, the evaluation value E is calculated after weighting the relaxation degree f1 and the concentration degree f2 based on the first weighting coefficient A and the second weighting coefficient B, respectively. .

  Each of the weighting factors A and B can arbitrarily set a real number in the range from “0” to “1”. As a result of further examination by the applicant of the above-mentioned examination, it has been found that the degree of relaxation f1 shows a more remarkable response to the romantic feeling than the degree of concentration f2. Therefore, based on such knowledge, the relationship between the individual coefficients A and B is set so that the relaxation degree f1 is dominant in the evaluation value E compared to the concentration degree f2. In this embodiment, “0.7” is set as the first coefficient A, “0.3” is set as the second coefficient B, and the evaluation value E is a value in the range from 0 to 100. It can take.

  However, the evaluation of the romantic feeling according to the degree of relaxation f1 and the degree of concentration f2 is derived from a statistical viewpoint as described above, and some differences may be considered depending on the subject. Therefore, the central processing unit 24 may display a setting screen on the operation display unit 23 prior to the execution of the love degree diagnosis and arbitrarily set the first and second weighting factors A and B by the user. In addition, the brain wave in the natural state of the subject and the brain wave in a state where various persons are viewed are measured in advance, and the central processing unit 24 automatically calculates the first and second weighting factors A and B based on the comparison between the two. May be set automatically.

  The central processing unit 24 determines the degree of love based on the evaluation value E. The evaluation value E can be used as it is for the degree of love, but in the present embodiment, according to the evaluation value E, “dislike”, “not interested”, “so-so”, “like” and “love” Diagnose romance as a word that the user can perceive. For example, the evaluation value E is divided into five groups from 0 to 100. A group including 0 to 19 as the evaluation value E is evaluated as “dislike”, and a group including 20 to 39 as the evaluation value E is evaluated as “not interested”. A group including 40 to 59 as the value E is associated with “OK”, a group including 60 to 79 as the evaluation value E is associated with “like”, and a group including 80 to 100 as the evaluation value E is associated with “love”. It is like leaving. Then, the central processing unit 24 identifies a group corresponding to the calculated evaluation value E, and determines a word associated with the identified group as a love degree.

  FIG. 3 is a flowchart showing the procedure of the love degree diagnosis executed by the central processing unit 24. The process shown in this flowchart is executed using a user's instruction to start a love degree diagnosis as a trigger, such as tapping an icon displayed on the operation display unit 23. The instruction to start the love degree diagnosis is performed on the premise that the brain wave sensor 10 is attached to the head of the subject, and after the start instruction or prior to the start instruction, the subject visually checks the person to be loved. It is preferable.

  First, in step 1 (S1), the central processing unit 24 determines whether or not a measurement state signal is input. If an affirmative determination is made in step 1, that is, if a measurement state signal is input, the process proceeds to step 2. On the other hand, if a negative determination is made in step 1, that is, if no measurement state signal is input, the processing returns to step 1. If the number of negative determinations in step 1 reaches a predetermined upper limit value, the electroencephalogram sensor 11 may not be properly worn, so it is desirable to end this process. At this time, the central processing unit 24 may display a message on the operation display unit 23 to prompt the user to reattach the electroencephalogram sensor 10.

  In step 2 (S2), the central processing unit 24 displays a message indicating that the electroencephalogram is being measured on the operation display unit 23. This display is continued until an affirmative determination is made in step 3 to be described later.

  In step 3 (S3), the central processing unit 24 determines whether or not the degree of relaxation f1 and the degree of concentration f2 as measurement data have been acquired via the input unit 21. If an affirmative determination is made in step 3, that is, if measurement data is acquired via the input unit 21, the process proceeds to step 4. On the other hand, if a negative determination is made in step 3, that is, if measurement data is not input to the input unit 21, the process returns to step 2. If the number of negative determinations in step 3 has reached a predetermined upper limit value, it is desirable that the processing is terminated because the measurement of the electroencephalogram may not be properly completed. At this time, the central processing unit 24 may display a message on the operation display unit 23 urging to redo the electroencephalogram measurement.

  In step 4 (S4), the central processing unit 24 diagnoses the degree of love. Specifically, the evaluation value E is calculated based on the relaxation degree f1 and the concentration degree f2. As a method for calculating the evaluation value E, the above-described Equation 1 can be used. Then, the central processing unit 24 determines the degree of love based on the calculated evaluation value E. That is, the central processing unit 24 determines a word associated with the evaluation value E as a love degree from among “dislike”, “not interested”, “so-so”, “like”, and “love”.

  In step 5 (S5), the central processing unit 24 displays the diagnosed love degree on the operation display unit 23, and then ends the present process.

  As described above, in the present embodiment, the central processing unit 24 of the love degree diagnostic apparatus 20 determines the degree of relaxation f1 of the subject specified based on the θ wave or the α wave and the subject specified based on the β wave or the γ wave. An evaluation value E is calculated on the basis of the concentration degree f2 and the degree of love is diagnosed based on the evaluation value E.

  According to this configuration, attention is paid to two parameters of a specific electroencephalogram wave correlated with romantic feelings, specifically, the relaxation degree f1 and the concentration degree f2, and by using these parameters, the subject's romantic feelings are used. Can be quantitatively evaluated. Thereby, a test subject's love degree can be diagnosed appropriately.

  In the present embodiment, the central processing unit 24 performs weighting based on the first weighting factor A corresponding to the degree of relaxation f1 and the second weighting factor B corresponding to the degree of concentration f2. An evaluation value E is calculated. In this case, the value of the first weighting factor A is set in a relative relationship with the second weighting factor B so that the relaxation degree f1 is dominant in the evaluation value E compared to the concentration degree f2. Yes.

  As described above, among the parameters of both the relaxation degree f1 and the concentration degree f2, the relaxation degree f1 tends to show a more remarkable response to the romantic feeling than the concentration degree f2. Therefore, by making the relaxation degree f1 dominant in the evaluation value E compared to the concentration degree f2, the electroencephalogram component resulting from the romantic feeling is easily reflected in the evaluation value E. Thereby, it becomes possible to appropriately diagnose the degree of love of the subject.

  In the present embodiment, the central processing unit 24 can change the first and second weighting factors A and B according to the values designated by the operation display unit 23. According to such a configuration, the diagnostic sensitivity can be changed according to the individuality of the subject, so that more users can accurately diagnose the degree of love using the apparatus 20 and improve the product appeal. Can be achieved.

  In this embodiment, the evaluation value E is calculated based on both the relaxation degree f1 and the concentration degree f2. However, even if the evaluation value E is calculated based only on the relaxation degree f1 or the concentration degree f2. Good. Further, the arithmetic function provided in the electroencephalogram sensor may be executed by the love degree diagnosis apparatus, and the electroencephalogram sensor may simply detect the electroencephalogram or extract the wave of each frequency. That is, the love degree diagnosis apparatus 20 of the present embodiment receives information on at least one of α wave, β wave, θ wave, and γ wave included in the brain wave, and this α wave, β wave, θ wave, and γ wave. Based on at least one of the above, the essence of diagnosing the degree of love of the subject with respect to the romance subject is essential.

  As mentioned above, although the love degree diagnostic system concerning embodiment of this invention was demonstrated, it cannot be overemphasized that a various deformation | transformation is possible within the scope of the invention, without this invention being limited to embodiment mentioned above. Absent. For example, it is not necessary for the love degree diagnostic apparatus to be used as a set with an electroencephalogram sensor, measurement data transmitted via a network, or measurement that is measured and stored in advance in a portable information recording medium such as a flash memory. Data may be input. In addition, in the measurement of the electroencephalogram used for diagnosis, it is preferable that the subject directly looks at the romance target, but it is in a state of indirectly observing the romance target shown in the photograph or video, The person may be in a state of imagining the person inside. Also, a love degree diagnosis apparatus that constitutes a love degree diagnosis system and a computer program that causes a computer to execute the above-described love degree diagnosis method also function as part of the present invention.
