DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a psychosomatic state awareness support device that promotes a subject's awareness of a coincidence or a difference between a subjective evaluation of a subject's mental and physical state and an objective measurement result.

[0002]

2. Description of the Related Art Conventionally, there is a stress level determining apparatus for measuring a stress level of a person by measuring biological signals such as heart rate data and brain waves. This is, as shown in FIG.
1, a task requiring concentration and a rest as a break are alternately imposed on the subject 1, the heart rate data collection unit 32 collects the subject's heart rate data, and the stress degree determination unit 33.
Then, the variation of the beat interval is obtained from the heart rate data, and the stress level of the subject is determined from the difference in the variation of the beat interval between the task and the rest. A similar one is described in Japanese Patent Application No. 8-123916. This stress level determination device, which has conventionally been determined based on a subjective sensory quantity, is objectively and quantitatively measured. Can be determined with high reliability.

[0003]

In recent years, people have been subjected to various stresses at work or in daily life. In particular, due to rapid OA (office automation) and FA (factory automation), VDT (video display terminal) work and monitoring work are increasing, and the stress caused by these work is a cause of overwork and human error. . Since the adverse effects of stress gradually accumulate, the subject is often unaware that the subject is mentally and physically good. In some cases, it is determined that the degree is high, and such self-confidence in the mental and physical condition may cause overwork. Also,
Even if the mental and physical condition based on the objective measurement is good, there is a case that the mental and physical condition is subjectively recognized to be poor due to an assumption or the like.

[0004] However, in the conventional stress degree judging apparatus, since the objective judgment is simply performed, even if there is a difference between the subjective evaluation of the mental and physical state of the subject and the objective judgment of the mental and physical state based on the measurement, the subject is evaluated. Cannot clearly recognize the difference. The present invention has been made in view of the above-described conventional problems, and has a psychosomatic state awareness support that enables a subject to clearly recognize a match or a difference between an evaluation of a subjective mental and physical state and an objective judgment of the mental and physical state by measurement. It is intended to provide a device.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides an objective mental and physical condition judging device which measures a subject's biological data and judges an objective mental and physical condition based on the biological data.
A questionnaire presentation device for presenting a questionnaire to a subject,
Based on the questionnaire results answered by the subject, a questionnaire determination device that determines the subjective mental and physical state of the subject, an objective mental and physical condition obtained by the physical and mental condition determination device, and a subjective mental and physical condition obtained by the questionnaire determination device It is assumed that the apparatus comprises a support determination device for comparing the mental and physical states and a display device for displaying a result of comparison between the support determination devices. It is preferable that the objective mental and physical condition determining device determines the degree of stress from the biological signal of the subject.

A new questionnaire presentation instructing device for instructing the subject to present a new questionnaire different from the above-mentioned questionnaire based on the comparison result of the support judging device can be provided. In the new questionnaire presentation instructing device, the support determination device has a predetermined or more difference between the objective mental and physical condition determined by the objective mental and physical condition determination device and the subjective mental and physical condition determined by the questionnaire determination device. When it is determined that the questionnaire exists, it is preferable to instruct the presentation of a new questionnaire.

[0007]

The psychosomatic state awareness support device according to the present invention compares an objective mental and physical state determined based on biological data with a subjective mental and physical state determined based on a questionnaire, and compares the comparison result with For example, if the mental and physical condition is judged to be stressed in the objective mental and physical condition judgment and the mental and physical condition is judged to be good in the subjective mental and physical condition judgment, "Be careful because there is stress." Conversely, if it is determined that there is no stress in the objective mental and physical condition determination and the mental and physical condition is determined to be not good in the subjective mental and physical condition determination, "There is no stress, so do not worry. , Please "can encourage the test subject to be aware of his or her own physical and mental state. Further, based on a comparison result of the objective mental and physical state and the subjective mental and physical state, for example, when a difference of a predetermined value or more occurs in the comparison result, a new questionnaire is presented to the subject, and the subjective The accuracy of the determination of the physical and mental state is improved.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to examples. FIG. 1 is a block diagram showing the configuration of the first embodiment. The mental and physical condition awareness support device measures a heartbeat-equivalent data, which is physical data of the subject 1, and determines a stress level as a physical and mental condition, a stress level determining device 2, a questionnaire presentation device 3 that presents a questionnaire A1 to the subject, and a subject. A questionnaire determination device 4 that determines the physical and mental state of the subject based on the questionnaire result answered by 1 and a support determination device that compares the stress level determined by the stress level determination device with the physical and mental state determined by the questionnaire determination device 5 and a display device 6 for displaying the result of comparison by the support determination device 5.

The stress degree determination device 2 alternately applies a task requiring concentration to the subject 1 and a rest to take a rest, collects data corresponding to the heart rate from the subject, and sets the RRI (R-R (interval) data is detected, a normalized variance RRV, which is a variation of the RRI data, is calculated from the RRI data, and the subject 1 is determined based on the difference in the RRV between the task performing the task and the rest at rest. Is determined, and is output to the support determination device 5 as an objective mental and physical condition determination value OB. On the other hand, the questionnaire presentation device 3 presents a questionnaire A1 as shown in FIG. 2 to the subject. This is ME (Medical E)
(A) is a part of a subjective fatigue survey table in a GS-D8L fatigue survey table used for a fatigue survey in a society, (a) is a questionnaire regarding physical fatigue, (b) is a mental activity It is a questionnaire about the degree.

In the questionnaire determination device 4, the subject's answer to the questionnaire A1 is input, the physical fatigue and mental activity of the subject 1 are calculated, and the subjective mind and body are calculated from the physical fatigue and mental activity. The state determination value S1 is obtained and output to the support determination device 5. In the support determination device 5, the objective mental and physical condition determination value OB determined by the stress level determination device 2
And the subjective mental and physical state determination value S1 determined by the questionnaire determination device 4 and outputs the comparison result to the display device 6. The display device 6 displays the comparison result using a text that prompts the subject 1 to be aware of his / her own physical and mental state. In addition,
The stress degree determination device 2 in the present embodiment constitutes the objective mental and physical condition determination device in the invention.

Next, the flow of operation in this embodiment is shown in FIG.
This will be described with reference to the flowchart shown in FIG. Step 10
In step 1, the objective mental and physical condition determination value OB is calculated from the stress level by the stress level determining device 2. First, R-wave, which is the heartbeat-equivalent data shown in FIG. 4, is sampled while alternately giving a task requiring concentration and a rest, which is a break, to detect a beat interval RRI. The normalized variance RRV of the beat interval RRI and the average heart rate BEAT are calculated as indices indicating the degree of variation in the RRI data. Normalized variance RRV and average heart rate BE for task time and rest time
The relationship with the AT is obtained as an area on a two-dimensional plane where the normalized variance RRV is displayed on the horizontal axis and the average heart rate BEAT is displayed on the vertical axis.

As shown in FIG. 5, the normalized variance RRV indicates that the average heart rate BEAT becomes higher toward the left, and the degree of concentration of the subject becomes higher toward the left. Conversely, the normalized variance RRV indicates that the subject is more relaxed as going to the right and the average heart rate BEAT is going down. Basically, a healthy person with a small stress level concentrates on the task and can relax on the rest, so the distribution areas at the time of the task and at the time of the rest are distributed at positions apart from each other. On the other hand, subjects with a high degree of stress often cannot concentrate on the task or cannot relax on the rest, and the distribution areas at the time of the task and at the time of the rest approach each other.

Here, the distribution areas are compared on a two-dimensional RRV-BEAT plane, and the stress ratio is determined by the overlap ratio of the distribution area area at the time of the task and the distribution area area at the time of the rest with respect to the distribution area area at the time of the task. The presence or absence is determined. When the overlapping ratio of the distribution area at rest to the distribution area at task is equal to or less than １ ／, the stress degree is determined to be small, and the objective mental and physical state determination value OB is set to zero. When the above-mentioned overlapping rate is 1/2 or more, it is determined that the stress degree is large, and the objective mental and physical condition determination value OB is set to 1. The calculated objective mental and physical state determination value OB is input to the support determination device 5.

In step 102, the questionnaire A1 shown in FIGS. 2A and 2B is presented to the subject 1 by the questionnaire presenting device 3. When the condition described in each item is applicable, enter a circle (〇) in the right column. In step 103, a physical fatigue feeling judgment value P1 and a mental activity degree judgment value M1 are calculated from the subject's answer to the presented questionnaire A1. When the questionnaire result is input to the questionnaire determination device 4, first, the questionnaire determination device calculates the ratio of circles to the questionnaire shown in FIG. If the ratio of circles is 50% or less, it is determined that the subjective physical fatigue is small, and the physical fatigue feeling determination value P1
Is set to 0, and when the ratio of circles exceeds 50%, it is determined that physical fatigue is large, and the physical fatigue feeling determination value P1 is set to 1. Next, the ratio of circles to the questionnaire shown in FIG. 2B is calculated. If the percentage of circles is 50% or less, the subjective mental activity is determined to be active,
The mental activity determination value M1 is set to 0, and the ratio of circles is 50%.
Is exceeded, it is determined that the mental activity is not active, and the mental activity determination value M1 is set to 1.

In step 104, first, as shown in FIG. 6, the logical sum of the physical fatigue feeling judgment value P1 and the mental activity degree judgment value M1 is obtained as a subjective mental and physical state judgment value S1, and output to the support judging device 5. I do. Next, in step 105, in the support determination device 5, as shown in FIG. 7, the objective mental and physical condition determination value OB determined by the stress degree determination device 2 and the subjective mental and physical condition determination determined by the questionnaire determination device 4 The value S1 is compared, and the comparison result is output to the display device 6. That is, as in the example at the top, the objective mental and physical condition determination value O
If both B and the subjective mental and physical state determination value S1 are 0, the determination results of the two match, indicating that the physical and mental state is good. Therefore, the comparison result is “no stress”. .

If the objective mental and physical condition judgment value OB and the subjective mental and physical condition judgment value S1 are both 1, as in the example in the second row, the judgment results of the two coincide with each other, indicating that the mental and physical condition is not good. Therefore, the result of the comparison is “stressed”. As in the example of the third row, if the objective mental and physical state determination value OB is 0 and the subjective mental and physical state determination value S1 is 1, the mental and physical state is good in the objective measurement with the stress level measurement device 2. Despite being determined to be present, the subject subjectively recognizes that the mental and physical condition is not good. In this case, the result of the comparison is "don't worry because there is no stress".

Further, as in the example of the fourth row, the objective mental and physical condition degree judgment value OB is 1, and the subjective mental and physical condition judgment value S1 is 0.
Then, in the objective measurement, it is subjectively recognized that the mental and physical condition is good even though it is determined that the mental and physical condition is not good. In this case, the comparison result is "Be careful because there is stress." In step 106, the display device 6 displays the determination result to prompt the subject 1 to be aware of his / her own physical and mental state.

In the present embodiment, the subjective mental and physical state determination value OB calculated from the heart rate data, and the subjective fatigue determination value P1 and the mental activity degree determination value M1 determined based on a questionnaire are determined. By comparing the target mental and physical state determination value S1 and displaying the comparison result, it is possible to promote the subject's awareness of the physical and mental state of the subject, so that the subject's excessive self-confidence and beliefs can be eliminated.

FIG. 8 is a block diagram showing the configuration of the second embodiment of the present invention. In this embodiment, two questionnaires are prepared, and in the support determination after the first questionnaire, when the objective mental and physical state determination value and the subjective mental and physical state determination value do not match, a detailed A second questionnaire describing the question items is made and the judgment is made again. The mental and physical condition awareness support device of the present embodiment is a stress degree determination device 2
A questionnaire presentation device 11 that presents a questionnaire to the subject 1, a questionnaire determination device 12 that determines the mental and physical state of the subject based on the questionnaire result answered by the subject,
The support determination device 13 that determines the stress level determined by the stress level determination device 2 by comparing the mental and physical state determined by the questionnaire determination device 12, the stress level determined by the stress level determination device 2, and the questionnaire determination A new questionnaire presentation instructing device 14 for instructing the presentation of a new detailed questionnaire when the support determining device 13 determines that the mental and physical states determined by the device 12 do not match, and the support determining device 1
3 comprises a display device 6 for displaying the comparison result.
The stress degree determination device 2 and the display device 6 have the same configuration as in the first embodiment.

The questionnaire presentation device 11 presents a questionnaire A1 as shown in FIG. 2 to the subject as the first questionnaire, as in the first embodiment. As the second questionnaire, a detailed questionnaire on physical fatigue and / or a detailed questionnaire on mental activity is presented. The questionnaire determination device 12 inputs the subject's answer to the above questionnaire, calculates a subjective mental and physical state determination value S1 from the first questionnaire result, and calculates a subjective mental and physical state determination value S2 from the second questionnaire result. Is output to the support determination device 13.

In the support determining device 13, the objective mental and physical condition determination value OB determined by the stress level determining device 2 and the subjective mental and physical condition determining value S obtained from the first questionnaire result are obtained.
1 are compared, and when they do not match, each determination value is output to the new questionnaire presentation instructing device 14. If they match, the comparison result is output to the display device 6. In addition, the support determination device 13 compares the subjective mental and physical condition determination value S2 obtained from the result of the second questionnaire with the objective mental and physical condition determination value OB, and then outputs the comparison result to the display device 6.

Next, the flow of operation in this embodiment will be described with reference to the flowcharts shown in FIGS. Steps 101 to 104 are the same as the flowchart of the first embodiment shown in FIG. In step 111, it is determined whether or not the result of the second questionnaire has already been input. If the result of the second questionnaire has already been input, the process proceeds to step 112. yet,
If the second questionnaire has not been completed, step 1
Proceed to 14. In step 112, as in step 105 of the flowchart shown in FIG. 3, comparison is performed, the comparison result is output to the display device 6, and in step 113, the comparison result is displayed.

In step 114, the support judging device 13
Calculates the judgment value coincidence EO by the exclusive OR of the objective mental and physical condition judgment value OB and the subjective mental and physical condition judgment value S1, as shown in FIG. In step 115, the judgment value matching degree E
It is determined whether O is 1 or not.
Proceed to 2. That is, if the objective mental and physical condition determination value OB and the subjective mental and physical condition determination value S1 match, step 1
Proceeding to 12, the comparison result is displayed in step 113. If the determination value matching degree EO is not 1, that is, if the objective mental and physical condition determination value OB does not match the subjective mental and physical condition determination value S1, the process proceeds to step 116. In step 116, the objective mental and physical condition judgment value OB and the physical fatigue feeling judgment value P
1 and the mental activity determination value M1 are input from the support determination device 12 to the new questionnaire presentation instruction device 14.

In step 117, the new questionnaire presentation instructing device 14 determines whether the objective mental and physical condition determination value OB matches the physical fatigue feeling determination value P1. If they do not match, the process proceeds to step 118, and if they do match, the process proceeds to step 120. In step 118, the questionnaire presentation device 11 is instructed to present the physical fatigue feeling detailed questionnaire A2 shown in FIGS.
This questionnaire A2 is used for subjective evaluation of physical fatigue in the ME Society, and FIG. 12 mainly shows decline in energy, general fatigue, physical upset, irritability and work motivation. FIG. 13 shows a questionnaire regarding retreat, anxiety, depression, and chronic fatigue. In step 119, the questionnaire presentation device 11 presents the physical fatigue detailed questionnaire A2 to the subject 1, and proceeds to step 120. The subject 1 circles the corresponding item of the questionnaire A2.

In step 120, it is determined whether or not the objective mental and physical state determination value OB matches the mental activity degree determination value M1. If they do not match, the process proceeds to step 121, and if they do match, the process proceeds to step 123. In step 121, the questionnaire presentation instructing device 14 instructs the questionnaire presenting device 11 to present the mental activity detail questionnaire A3 shown in FIGS. The questionnaire A3 is used for subjective evaluation of mental activity in the ME Society. 14 (a) shows items related to tension, (b) shows depression, (c) shows anger, FIG. 15 (d) shows activity, (e) shows fatigue,
(F) shows items related to emotional confusion. In step 122, the questionnaire presentation device 11 presents the mental activity detail questionnaire A3 to the subject 1, and proceeds to step 123. The subject responded to the questionnaire A3 as "0; not at all", "1; it cannot be said at all", "2; nothing can be said".
"3; the tendency is strong.", "4; exactly so."
Enter the score that you think best describes your condition.

That is, if the objective mental and physical condition judgment value OB does not match the subjective mental and physical condition judgment value S1, 3
The case is as follows. First, although the objective mental and physical state determination value OB and the mental activity degree determination value M1 match,
If the physical fatigue feeling determination value P1 is different, step 11
7 to steps 118 and 119, and step 120
To step 123. That is, only the physical fatigue feeling detailed questionnaire A2 is presented again to the subject 1.

Second, when the objective mental and physical condition judgment value OB and the physical fatigue feeling judgment value P1 match, but the mental activity judgment value M1 is different, the process proceeds from step 117 to step 120 and step 121. Then, only the mental activity detail questionnaire A3 is re-presented to the subject 1. Third,
Physical fatigue feeling judgment value P1 and mental activity degree judgment value M1
Are different from the objective mental and physical condition determination value OB,
Through all the steps from step 117 to step 123, both the physical fatigue detailed questionnaire A2 and the mental activity degree detailed questionnaire A3 are presented to the subject 1.

In step 123, first, the questionnaire judgment device 12 inputs the presented questionnaire result of the detailed questionnaire, and calculates a physical fatigue feeling judgment value P2 and a mental activity degree judgment value M2. When the physical fatigue feeling detailed questionnaire A2 is presented, the ratio of circles to this questionnaire is calculated. If the ratio of the circles is 50% or less, it is determined that the physical fatigue is small, and the physical fatigue feeling determination value P2 is set to 0. If the ratio of circles exceeds 50%, it is determined that the physical fatigue is large, and the physical fatigue feeling determination value P
2 is set to 1.

When the mental activity detail questionnaire A3 is presented, a determination value is calculated using the mental activity determination table shown in FIG. The points entered for each item are added to obtain a total score, and a score is calculated as the total score / reference value. However, in the question 22 shown in FIG. 14A and the question 54 shown in FIG. 15F, the score is not added to the scoring but is subtracted. If the value obtained by subtracting the average of the scores other than the activity from the activity score is 0.5 or more, the mental activity is determined to be active, and the mental activity determination value M2 is set to 0. , 0.5, it is determined that the mental activity is not active, and the mental activity determination value M2 is 1.

In step 124, the logical OR of the physical fatigue feeling judgment value P2 and the mental activity degree judgment value M2 is calculated, and the process returns to step 111 as the subjective mental and physical state judgment value S2. If the physical fatigue feeling detailed questionnaire A2 or the mental activity detail questionnaire A3 is not presented, the physical fatigue feeling determination value P obtained from the first questionnaire result
1 and the mental activity determination value M1 are used. Step 11
In step 1, since the second questionnaire has been presented, the process proceeds to step 112, where the support determination device 13 compares the objective mental and physical condition determination value OB with the subjective mental and physical condition determination value S2. Displays the comparison result.

In this embodiment, the objective mental and physical condition determination value OB
If the value of the subjective mental and physical condition determination value S1 obtained from the first questionnaire A1 does not match,
The second detailed questionnaire is presented, and the subjective mental and physical condition determination value S2 calculated based on the detailed questionnaire results
By comparing again with the objective mental and physical condition determination value OB and displaying the comparison result, the determination accuracy of the support determination can be improved. When a new questionnaire is presented to the subject, only the physical fatigue level determination value P1 and the mental activity level M1 that do not match the objective mental and physical state determination value OB are determined. By presenting the detailed questionnaire again, the judgment accuracy of the subjective mental and physical condition judgment value can be improved with a minimum number of interviews.

A data management device can be connected to the mental and physical condition awareness support device of this embodiment. FIG. 17 shows an example in which the display device 6 and the support determination device 13 of the same mental and physical condition awareness support device as shown in FIG.
It is connected to the data management device 21. An input device 23 is connected to the communication device 22. The communication device 22 transmits all the measurement results and the determination values of the subject 1 in the support determination device 13 to the data management device 21.
The data management device 21 manages the transmitted data.
If necessary, the input device 23 is used to specify data to be read from the data management device 21. The data read from the data management device 21 is displayed on the display device 6 via the communication device 22.

By connecting the data management device 21, the data measured and stored in the past for the same subject can be read out and displayed, and can be compared with the data measured this time. Since the change in the mental and physical condition can be visually observed, the subject's awareness of the physical and mental condition of the subject can be further promoted. Further, since the mental and physical condition awareness support device and the data management device 21 can be installed at a distance, data measured by the mental and physical condition awareness support device installed at home is monitored at a hospital or the like where the data management device 21 is installed. And the convenience of the mental and physical condition awareness support device is improved.

In each of the above embodiments, a stress level determining apparatus for determining a stress level from heart rate data is used as an objective mental / physical state determining apparatus. However, the present invention is not limited to this. A device that determines the degree of stress may be used as long as it can determine the mental and physical condition objectively.

[0035]

As described above, the psychosomatic state awareness support device according to the present invention is capable of comparing an objective psychosomatic state determined based on biometric data with a subjective psychosomatic state determined based on a questionnaire. By comparing and displaying the comparison result, it is possible to encourage the subject to be aware of his or her own physical and mental state. Even if you think that your mental and physical condition is good, the subject determined to have a large stress in the objective mental and physical condition determination result obtained by measuring the biometric data can be careful not to overdo it anymore, In addition, even if the user considers that the mental and physical condition is not good, the subject who is determined to have no stress in the objective mental and physical condition determination result can be released from the assumption.

Further, based on the comparison result between the objective mental and physical state and the subjective mental and physical state, for example, when a difference of a predetermined value or more occurs in the comparison result between the subjective mental and physical states, a new questionnaire is generated. By presenting to the subject, the accuracy of judgment of the subjective mental and physical condition is improved, and the reliability of the comparison result between the objective mental and physical condition and the subjective mental and physical condition is improved.
