Description

  The present invention relates to a fatigue level evaluation system.

  A system that quantitatively evaluates the degree of fatigue is disclosed, for example, in Patent Document 1. The system disclosed in Patent Document 1 calculates a comprehensive fatigue degree evaluation value from the objective fatigue degree (LF value / HF value) and the subjective fatigue degree (factor analysis value). The LF value / HF value is calculated by frequency analysis of the pulse wave of the subject or the heart beat of the subject to obtain a low frequency component (LF value) and a high frequency component (HF value). That is, the LF value / HF value indicates the disturbance of the autonomic nerve. Therefore, the LF value / HF value indicates the objective fatigue level of the subject. On the other hand, factor analysis values are obtained from the results of the subjects' responses to the interview. Therefore, the factor analysis value indicates the degree of subjective fatigue that the subject feels.

  According to the system disclosed in Patent Document 1, it is possible to present the subject with an objective fatigue degree, a subjective fatigue degree, and a fatigue degree (total fatigue degree evaluation value) integrating them.

  The input unit 3 inputs various types of information to the calculation unit 2. The input unit 3 may include an input device such as a keyboard or a touch panel. In addition, the input unit 3 may include a communication interface that receives information transmitted from an external device such as a personal computer. In addition, the input unit 3 may include an apparatus or mechanism for reading out information (data) from the information carrier. For example, the input unit 3 may include an optical disk drive capable of reading information (data) from an optical disk such as a CD (Compact Disc) or a DVD (Digital Versatile Disc). Also, the input unit 3 may include a USB interface to which a USB (Universal Serial Bus) memory is connected.

  The storage unit 4 stores various types of information such as programs and setting values. The storage unit 4 may include a storage device such as a read only memory (ROM), a random access memory (RAM), or a hard disk drive (HDD).

  The output unit 5 outputs an image. The output unit 5 may include a display device such as a liquid crystal display device. The display device displays (outputs) an image. In addition, the output unit 5 may include a printing device such as a printer. The printing apparatus forms (outputs) an image on a recording material such as paper.

  In the present embodiment, the operation unit 2 specifies one first mark corresponding to the first measurement result indicating the objective fatigue degree of the subject among the first mark group indicating the objective fatigue degree in stages. . Further, the calculation unit 2 specifies one second mark corresponding to the second measurement result indicating the subject's subjective fatigue degree out of the second mark group indicating the subjective fatigue degree in stages. The calculation unit 2 further generates image data of the fatigue level evaluation image based on the first measurement result and the second measurement result. Alternatively, the calculation unit 2 may generate the image data of the fatigue level evaluation image based on the combination of the designated first mark and the designated second mark. The first mark group and the second mark group are stored in advance in the storage unit 4.

  The first measurement result is input to the calculation unit 2 via the input unit 3. For example, the first measurement result can be input to the calculation unit 2 by the user operating the keyboard. Alternatively, the first measurement result may be transmitted from the external device and may be input to the computing unit 2 through the communication interface. Alternatively, the first measurement result recorded on the optical disc may be read by the optical disc drive and input to the calculation unit 2, or the first measurement result stored by the USB memory may be calculated via the USB interface. It may be input to part 2. Similarly to the first measurement result, the second measurement result can also be input to the calculation unit 2 through the input unit 3.

  The fatigue level evaluation image includes a first image in which the designated first mark and the designated second mark are arranged in the fatigue level evaluation region. The storage unit 4 stores in advance a layout image (image data) of the fatigue level evaluation area. The designated first mark and the designated second mark are arranged at positions according to the first measurement result and the second measurement result. Alternatively, the two marks are arranged at positions according to the combination of the designated first mark and the designated second mark.

Alternatively, in accordance with the combination of the designated first mark and the designated second mark, the positions at which the two marks are arranged change.

  The output unit 5 outputs a fatigue level evaluation image based on the image data generated by the calculation unit 2. For example, when the output unit 5 includes a display device, the calculation unit 2 generates image data in a format that can be displayed by the display device. Based on the image data, the display device displays (outputs) the fatigue level evaluation image. When the output unit 5 includes a printing device, the computing unit 2 generates image data in a format that allows printing by the printing device. Based on the image data, the printing apparatus prints (outputs) a fatigue level evaluation image on a recording material such as a sheet.

The objective fatigue degree can be acquired, for example, using the following data (measured values). The objective fatigue level may be acquired from one of the following data or may be acquired by combining two or more of the following data.
・ Autonomic nervous function ・ Life log such as activity amount and sleep condition ・ Blood pressure ・ Blood component ・ Saliva component ・ Concentration of physiologically active substance (hormone) ・ Concentration of antioxidants ・ Concentration of metabolite ・ Virus in the body

  For example, as the objective fatigue degree, an LF value / HF value, which is a type of data on autonomic nervous function, can be adopted. The LF value / HF value indicates the disorder of the autonomic nervous function. In this case, the first measurement result (measured value) is the subject's LF value / HF value. The LF value / HF value can be calculated by frequency analysis of a pulse wave or a heart beat to obtain a low frequency component (LF value) and a high frequency component (HF value). According to the LF value / HF value, enhancement of sympathetic nerve function, which is a type of autonomic nervous function, can be evaluated. Thus, the objective fatigue level of the subject can be evaluated from the LF value / HF value. Alternatively, as the objective fatigue degree, an addition value of the LF value and the HF value (hereinafter, described as a total power value) can be adopted. In this case, the first measurement result (measured value) is a total power value of the subject. The total power value is a type of data on autonomic nervous function, and indicates the function of the autonomic nervous function as a whole. Therefore, the subject's objective fatigue level can be evaluated from the total power value. Alternatively, the objective fatigue level can be obtained based on the LF value / HF value and the total power value.

  The first mark group may be a mark group capable of dividing objective fatigue degree in stages. For example, a face mark group may be used as the first mark group. In the present embodiment, three types of face marks are used as the first mark group. That is, in the present embodiment, the objective fatigue degree is divided into three stages. Therefore, the operation unit 2 specifies one face mark corresponding to the first measurement result of the subject among the three types of face marks. For example, when adopting the LF value / HF value as the objective fatigue degree, the first range of 0.0 or more and less than 0.8 and 2.0 or more and less than 5.0, the first range of 0.8 or more and less than 2.0 The LF value / HF value (measured value) can be divided into three steps of a range of 2 and a third range of 5.0 or more. In this case, when the subject's LF value / HF value is within the first range, a face mark indicating "attention" is designated. If the subject's LF value / HF value is within the second range, a face mark indicating "good" is specified. If the subject's LF value / HF value is within the third range of values, a face mark indicating “careful” is designated.

On the other hand, the degree of subjective fatigue may be acquired, for example, using the following data (measured values). The subjective fatigue degree may be acquired from one of the following data or may be acquired by combining two or more of the following data.
・ Answer to a medical questionnaire (question sheet) in which each question item pertaining to fatigue is listed ・ Answer to a medical inquiry chart (question sheet) in which each query item pertaining to learning will and lifestyle is described Answers to Visual Analog Scale) Answers to face scale for evaluating fatigue level Answers to scale for evaluating subjective mood such as KOKORO scale

  For example, when acquiring the degree of subjective fatigue from the answer to a questioning table (hereinafter referred to as a questioning table related to fatigue) in which each question item relating to fatigue is described, the answer to each question item is scored The degree of physical fatigue. In this case, the score (score) obtained from the test subject's answer to each question item is the second measurement result (measured value).

  The 2nd mark group should just be a mark group which can classify a degree of subjective fatigue in steps. For example, face marks may be used as the second mark. In the present embodiment, the same three types of face marks as the first mark group are used as the second mark group. In other words, the subjective fatigue degree is divided into three stages, as is the objective fatigue degree. Therefore, the calculation unit 2 specifies one face mark corresponding to the second measurement result (measured value) of the subject among the three types of face marks. For example, when acquiring the degree of subjective fatigue from the answer result to the medical interview table regarding fatigue, the operation unit 2 designates one face mark corresponding to the score (score) obtained from the answer result of the subject to each question item. For example, the score (measured value) acquired from the answer result to the medical inquiry table concerning fatigue is a first range of 0 or more and less than 33, a second range of 33 or more and less than 81, and 3 of the 81 or more third range. It can be divided into two stages. In this case, when the subject's score is a value in the first range, a face mark indicating "good" is specified. If the subject's score is a value in the second range, a face mark indicating "attention" is specified. When the subject's score is a value in the third range, a face mark indicating "careful" is designated.

  For example, a questionnaire shown in FIGS. 2 and 3 can be used as a questionnaire about fatigue. FIG. 2 is a diagram showing a part of the first interview sheet. FIG. 3 is a diagram showing a part of the second interview sheet. As shown in FIG. 2 and FIG. 3, by using the interview sheet, it is possible to obtain a subject's answer to various questions concerning fatigue. Therefore, it is possible to evaluate the subjective fatigue degree felt by the subject more multilaterally by including the response result to the questionnaire on fatigue related data in the data used for acquiring the subjective fatigue degree . Also, as shown in FIG. 2 and FIG. 3, by using the questionnaire regarding fatigue, not only the degree of fatigue that the subject is currently feeling, but also the fatigue that the subject felt in a certain period (for example, the past 1 month) It is possible to evaluate the degree. Note that one or both of the inquiry tables shown in FIGS. 2 and 3 may be used.

  Subsequently, three types of face marks 11 to 13 used in the present embodiment will be described with reference to FIG. FIG. 4 is a diagram showing three types of face marks 11-13. In the present embodiment, three types of face marks 11 to 13 are used as the first mark group and the second mark group. The face mark 11 indicates "good". The face mark 12 indicates "attention". The face mark 13 indicates "careful".

  Subsequently, with reference to FIG. 5, the fatigue degree evaluation image will be described. FIG. 5 is a view showing an example of the fatigue level evaluation image. Specifically, FIG. 5 shows a fatigue level evaluation image which is output when objective fatigue level is acquired from data on autonomic nervous function and a subjective fatigue level is acquired from a result of an answer to a questionnaire on fatigue. Further, in FIG. 5, as the first face mark 10a (an example of the first mark), the face mark 11 is designated according to the first measurement result of the subject, and the second face mark 10b (an example of the second mark) As shown, the fatigue degree evaluation image output when the face mark 11 is designated according to a test subject's 2nd measurement result is shown.

  As shown in FIG. 5, the fatigue level evaluation image includes the first image 31 in which the first face mark 10 a and the second face mark 10 b are disposed in the fatigue level evaluation area 20. Further, in the present embodiment, the fatigue level evaluation image includes the second image 32 presenting fatigue level reducing advice and the third image 33 presenting a list of fatigue level reducing advice, and the second image 32 is a first image. The face mark 10a and the second face mark 10b are arranged side by side.

  Specifically, the third image 33 presents nine (one example of a plurality of types) fatigue degree reduction advices and reference symbols A to I for identifying them. The calculation unit 2 described with reference to FIG. 1 selects one of nine fatigue degree reduction advices according to the first measurement result and the second measurement result. Alternatively, the calculation unit 2 selects one of the nine fatigue degree reduction advices according to the combination of the first face mark 10a and the second face mark 10b. Then, the second image 32 presents a reference symbol ("A" in the example shown in FIG. 5) corresponding to the selected fatigue level reduction advice.

  The fatigue level reduction advice presents a method for reducing fatigue level, and the third image 33 (list of fatigue level reduction advices) contains combinations of objective fatigue level and subjective fatigue level. Fatigue level reduction advice is presented. That is, in the third image 33, fatigue degree reduction advice for each combination of the first face mark 10a and the second face mark 10b is presented. It is preferable that the method for reducing the degree of fatigue indicated by the fatigue degree reducing advice is a method that has been scientifically recognized as effective. For example, as the fatigue level reduction advice, an advice such as “Recommended to take a bath for ○ ° C. for at least 日 ° C. for at least 日 day in a week” may be adopted. The third image 33 may present an explanatory note explaining the relationship between the measured degree of objective fatigue of the subject, the degree of subjective fatigue, and each degree of fatigue together with the fatigue degree reduction advice.

  In the present embodiment, the fatigue level evaluation area 20 is divided into a first quadrant 21 to a fourth quadrant 24 (an example of a plurality of areas). In this way, in the fatigue level evaluation area 20 divided into a plurality of areas (in the present embodiment, the first quadrant 21 to the fourth quadrant 24), positions (or the second measurement results) corresponding to the first measurement result and the second measurement result The first face mark 10a and the second face mark 10b are arranged at a position corresponding to the combination of the first face mark 10a and the second face mark 10b. By dividing the fatigue level evaluation area 20 into a plurality of areas in this manner, it becomes easy to grasp the subject's objective fatigue level and subjective fatigue level.

  Furthermore, in the present embodiment, the fatigue level evaluation region 20 is divided into a first quadrant 21 to a fourth quadrant 24 by the first axis 41 and the second axis 42 which intersect with each other. The first axis 41 indicates an objective degree of fatigue. More specifically, the first axis 41 indicates that the objective fatigue degree is better toward the right in FIG. Also, the second axis 42 indicates the subjective fatigue degree. Specifically, the second axis 42 indicates that the subjective fatigue degree is better toward the upper side in FIG. By thus dividing the fatigue level evaluation region 20 into the first quadrant 21 to the fourth quadrant 24 by the first axis 41 and the second axis 42, the objective fatigue level and the subjective fatigue level of the subject are grasped. It will be easier. For example, as shown in FIG. 5, when the first face mark 10a and the second face mark 10b are both face marks 11, the first face mark 10a and the second face mark 10b are arranged in the first quadrant 21. . By arranging the first face mark 10a and the second face mark 10b in the first quadrant 21 as described above, it is possible that the subject has both of his objective fatigue degree and his subjective fatigue degree. It can be easily determined.

  Preferably, as shown in FIG. 5, information is presented near the first face mark 10a to teach that the first face mark 10a indicates the degree of fatigue based on the autonomic nervous function. Thereby, the subject can easily judge that the first face mark 10a indicates the degree of fatigue based on the autonomic nervous function. Similarly, in the vicinity of the second face mark 10b, information is presented that teaches that the second face mark 10b indicates the degree of fatigue based on the medical examination table. Thereby, the subject can easily judge that the second face mark 10b indicates the degree of fatigue based on the medical inquiry table.

  Subsequently, referring to FIG. 6, a first face mark 10a (a face mark indicating an objective fatigue degree) and a second face mark 10b (a face mark indicating a subjective fatigue degree) which can be arranged in the fatigue degree evaluation area 20 The combination of FIG. 6 is a view showing sets 51 to 59 of the first face mark 10a and the second face mark 10b. In FIG. 6, together with the sets 51 to 59 of the first face mark 10a and the second face mark 10b, the selection is made corresponding to the sets 51 to 59 of the first face mark 10a and the second face mark 10b. Shows a second image 32 to be displayed. As shown in FIG. 6, when the objective fatigue degree and the subjective fatigue degree are divided into three levels, it is possible to set nine types of face marks.

  7 to 10, each set 51 to 59 of the first face mark 10a and the second face mark 10b (hereinafter referred to as a set 59 of the first face mark set 51 to the ninth face mark). ) May be described in the fatigue degree evaluation area 20. The position at which the first set of face marks 51 shown in FIG. 6 is arranged has already been described with reference to FIG.

  As shown in FIG. 7, when the face mark 11 is designated as the first face mark 10 a and the face mark 12 is designated as the second face mark 10 b, the second set 52 of face marks is arranged in the second quadrant 22. Be done.

  Although not shown, the third set of face marks 53 and the fourth set of face marks 54 shown in FIG. 6 are also arranged in the second quadrant 22 similarly to the second set of face marks 52. The third set 53 of face marks includes the face mark 11 as the first face mark 10a and the face mark 13 as the second face mark 10b. The fourth set of face marks 54 includes the face mark 12 as the first face mark 10 a and the face mark 13 as the second face mark 10 b.

  However, in the second quadrant 22, the second set of face marks 52, the third set of face marks 53, and the fourth set of face marks 54 may be arranged at different positions. Specifically, the second set of face marks 52, the third set of face marks 53, and the fourth set of face marks 54 may approach the first axis 41 in this order. That is, the higher the degree of fatigue which is comprehensively evaluated the objective degree of fatigue and the degree of subjective fatigue, the lower the position in the second quadrant 22 is the set of the first face mark 10a and the second face mark 10b. It may be done.

  Further, as shown in FIG. 8, when the face mark 12 is designated as the first face mark 10a and the face mark 12 is designated as the second face mark 10b, the fifth set 55 of the face marks is the first axis. It is arrange | positioned in the area | region where 41 and the 2nd axis | shaft 42 cross | intersect.

  Further, as shown in FIG. 9, when the face mark 12 is designated as the first face mark 10a and the face mark 11 is designated as the second face mark 10b, the sixth set 56 of the face marks is the fourth quadrant 24. Will be placed.

  Although not shown, a seventh set of face marks 57 and an eighth set of face marks 58 shown in FIG. 6 are also arranged in the fourth quadrant 24 in the same manner as the sixth set of face marks 56. The seventh face mark set 57 includes the face mark 13 as the first face mark 10 a and the face mark 11 as the second face mark 10 b. The eighth face mark set 58 includes the face mark 13 as the first face mark 10 a and the face mark 12 as the second face mark 10 b.

  However, in the fourth quadrant 24, the sixth set of face marks 56, the seventh set of face marks 57, and the eighth set of face marks 58 may be arranged at different positions. Specifically, the sixth set of face marks 56, the seventh set of face marks 57, and the eighth set of face marks 58 may move away from the first axis 41 in this order. That is, the higher the degree of fatigue which is comprehensively evaluated the objective degree of fatigue and the degree of subjective fatigue, the lower the position in the fourth quadrant 24 is the set of the first face mark 10a and the second face mark 10b. It may be done.

  Further, as shown in FIG. 10, when the face mark 13 is designated as the first face mark 10a and the face mark 13 is designated as the second face mark 10b, the ninth face mark set 59 is in the third quadrant 23 Will be placed.

  The first set of face marks 51 to the set of ninth face marks 59 may be arranged according to the two-dimensional coordinate position corresponding to the objective fatigue degree and the subjective fatigue degree. Specifically, based on the first measurement result (measured value), the operation unit 2 obtains a value of 0 or more and 100 or less corresponding to the objective fatigue degree of the subject, and the second measurement result (measured value) Based on the value, 0 or more and 100 or less corresponding to the subject's subjective fatigue degree is determined. That is, the first measurement result and the second measurement result are respectively converted into values corresponding to the rectangular uniform coordinate system. Then, the operation unit 2 sets the first face mark 10 a and the second face mark 10 b in accordance with the two-dimensional coordinate position (coordinate position in the rectangular uniform coordinate system) corresponding to the objective fatigue degree and the subjective fatigue degree. Arrange the set of In this case, scale data of 0 or more and 100 or less is given to the first axis 41 and the second axis 42.

  The first embodiment has been described above. According to the first embodiment, by presenting the fatigue level evaluation image to the subject, the positions of the first face mark 10a and the second face mark 10b in the fatigue level evaluation region 20, and the first face mark 10a and the second face mark 10a. The subject can easily judge his or her objective fatigue degree, subjective fatigue degree, and fatigue degree integrated with them from each type (face expression) of the face mark 10 b. Therefore, compared with the case where the objective fatigue degree, the subjective fatigue degree, and the fatigue degree which integrated them were shown separately, a fatigue degree can be shown to a test subject efficiently.

  Also, by presenting the subject with the objective fatigue level and the subject with the subjective fatigue level only, the subject should be able to comprehend his own fatigue level from the expression of each of the two face marks. Although it is possible, by disposing the first face mark 10a and the second face mark 10b in the fatigue level evaluation area 20 as in the first embodiment, the subject's degree of fatigue is greater than in the case where only the face mark is used. It becomes possible to grasp more easily (intuitively). In addition, after dividing a two-dimensional coordinate space including the X axis indicating the objective fatigue degree and the Y axis indicating the subjective fatigue degree into a plurality of evaluation areas, the objective fatigue degree and the subjective fatigue degree of the subject The degree of fatigue can also be presented to the subject by plotting a mark (for example, a black circle) at the intersection, but as in the first embodiment, the first face mark 10a and the second face mark 10b are fatigued By arranging in the evaluation area 20, it is possible for the subject to grasp his / her fatigue degree more easily (intuitively) than when using only a two-dimensional coordinate space divided into a plurality of evaluation areas. Become. For example, subjects of the elderly and lower age groups (e.g., infants and elementary school students) may not be able to read two-dimensional coordinates. On the other hand, according to the first embodiment, in the two-dimensional coordinate space, a mark (in the present embodiment, a face mark having an expression according to the fatigue level) indicating the fatigue level is arranged. Even in the case of a low-age subject, it is possible to intuitively (instantly) grasp the degree of fatigue of itself as compared with the case where a mark such as a black circle is arranged in the two-dimensional coordinate space.

  Further, according to the first embodiment, the face marks (the first face mark 10a and the second face mark 10b) are used for the mark indicating the subjective fatigue degree and the mark indicating the objective fatigue degree. Thus, the subject can more easily determine the degree of fatigue of the subject from the types (expressions) of the first face mark 10a and the second face mark 10b. In particular, the fatigue level evaluation area 20 is divided into four quadrants (four areas) deep to a general person by the first axis 41 and the second axis 42, and then face marks (the first face mark 10a and the second face) are formed. By using the mark 10b), it becomes possible for the subject to grasp more intuitively his or her objective fatigue level, subjective fatigue level, and fatigue level integrated with them. Therefore, it becomes easier to understand the degree of fatigue, and the convenience of the user is improved.

  Moreover, when presenting a LF value / HF value by a graph as it is, the graph of a double logarithmic coordinate system is employ | adopted. However, because the graph of the log-log coordinate system is not familiar to the general public, even if the graph of the log-log coordinate system is presented, the subject may not be able to judge his or her objective fatigue level . On the other hand, according to the first embodiment, even in the case of adopting the LF value / HF value as the actual measurement value of the subjective fatigue degree, the pair of the first face mark 10a and the second face mark 10b has double logarithmic coordinates. It can be placed on a rectangular uniform coordinate system familiar to the general public rather than a system. Therefore, according to the first embodiment, compared with the case of presenting the graph of the double logarithmic coordinate system to the subject, the subject is allowed to instantly (intuitively) understand the subject's degree of fatigue (objective degree of fatigue) It becomes possible.

  Further, according to the first embodiment, it is possible to present the subject with fatigue degree reduction advice according to the combination of the objective fatigue degree and the subjective fatigue degree. Therefore, the convenience of the fatigue level evaluation system 1 can be improved.

  Further, according to the first embodiment, the second image 32 (reference symbol) is arranged side by side with the first face mark 10a and the second face mark 10b. Thereby, the subject who has been presented with the fatigue level evaluation image can more easily determine which advice should be referred to.

  Also, for example, one month by arranging the first set of face marks 51 to the set of ninth face marks 59 according to the two-dimensional coordinate position corresponding to the objective fatigue degree and the subjective fatigue degree. The change in position of the set of the first face mark 10a and the second face mark 10b obtained from each measurement makes it possible to capture the transition of the degree of fatigue of the subject.

  In the first embodiment, the fatigue level evaluation area 20 is divided into four areas (first quadrant 21 to fourth quadrant 24), but the number of divisions of fatigue level evaluation area 20 is limited to four. It is not a thing. For example, the fatigue level evaluation area 20 can be divided into two areas. FIG. 11 is a view showing a modification of the fatigue level evaluation image. In the example shown in FIG. 11, the first axis 41 is disposed at the lower side of the fatigue level evaluation area 20. Further, the second axis 42 stands vertically from the center of the lower side (first axis 41) of the fatigue level evaluation region 20.

Second Embodiment
Subsequently, a second embodiment will be described with reference to FIGS. 1 and 12. However, matters different from the first embodiment will be described, and description of the same matters as the first embodiment will be omitted. The second embodiment differs from the first embodiment in the fatigue level evaluation image.

  First, with reference to FIG. 1, a fatigue degree evaluation system according to a second embodiment will be described. In the second embodiment, fatigue is calculated based on the first measurement result (measured value) indicating the objective fatigue level of the subject and the second measurement result (measured value) indicating the subjective fatigue level of the subject. The coordinate position in the degree evaluation area 20 (hereinafter referred to as fatigue degree coordinate) is calculated. In addition, the calculation unit 2 generates a history table in which the fatigue degree coordinate at each date and time is recorded in association with the date and time when the first measurement result and the second measurement result are acquired. The history table is stored in the storage unit 4. Then, the calculation unit 2 generates, based on the history table, image data of a fatigue level evaluation image including the first image 31 in which the mark is plotted on the fatigue level coordinate of each date and time.

  FIG. 12 is a view showing a fatigue degree evaluation image according to the second embodiment. More specifically, FIG. 12 shows a fatigue level evaluation image including a first image 31 in which marks are plotted on the first coordinate date a, the second coordinate date b, and the third coordinate date c. Is shown.

  In the second embodiment, as shown in FIG. 12, the image of the first face mark 10a and the image of the second face mark 10b are the same as in the first embodiment, the first face mark 10a and the second face mark 10b. And the second image 32 corresponding to the combination of The first face mark 10a and the second face mark 10b arranged in the fatigue level evaluation area 20 correspond to the first measurement result and the second measurement result obtained this time, that is, the latest first measurement result and the second measurement result. doing.

  The second embodiment has been described above. According to the second embodiment, the subject can confirm the transition (history) of his / her fatigue level (objective fatigue level and subjective fatigue level). Therefore, it becomes possible to determine whether or not the subject's fatigue level could be reduced by the subject's daily life following the advice.

  Further, in the second embodiment, the fatigue degree coordinate is calculated. Therefore, the position at which the mark is plotted in the fatigue level evaluation area 20 can be finely defined. Therefore, the subject can grasp his objective fatigue degree and his subjective fatigue degree from the position where the mark is plotted.

  In addition, when presenting the history of the objective fatigue degree and the subjective fatigue degree, generally three variables (in the present embodiment, the subjective fatigue degree, the objective fatigue degree, and the measurement date and time) are required. In other words, the history of objective fatigue and subjective fatigue is presented by three-dimensional orthogonal coordinates. On the other hand, according to the second embodiment, one or two variables can be presented to the subject not by coordinate positions but by face marks. Therefore, since the history of the degree of fatigue can be presented two-dimensionally, the subject can easily grasp the history of the degree of fatigue of the subject.

  In the second embodiment, the history table is generated and the mark is plotted on the fatigue degree coordinate of each date and time, but the fatigue degree coordinate corresponding to the latest first measurement result and second measurement result is described. Only marks may be plotted.

  In the second embodiment, the first face mark 10a and the second face mark 10b corresponding to the latest first measurement result and second measurement result are arranged in the fatigue level evaluation area 20, but The first face mark 10 a and the second face mark 10 b may be disposed outside the fatigue level evaluation area 20.

  The embodiments of the present invention have been described above with reference to the drawings. According to the embodiment of the present invention, the degree of fatigue can be efficiently presented to the subject. In other words, it is possible to make the subject easily (intuitively) understand the objective fatigue state and the subjective fatigue state. In particular, the fatigue evaluation area 20 is divided into four quadrants familiar to the general public, and a face mark indicating objective fatigue degree and a face mark indicating subjective fatigue degree are arranged in any one quadrant. The subject can grasp intuitively his or her objective fatigue degree, subjective fatigue degree, and fatigue degree integrated with them. Therefore, it becomes easier to understand the degree of fatigue, and the convenience of the user is improved.

  In addition, evaluation of fatigue is required not only for the adult population but also for the elderly and lower age groups. According to the embodiment of the present invention, numerical data that is difficult to read unless it is a medical person can be presented by replacing it with a mark that can be intuitively understood by a subject in the elderly group or a subject in the lower age group. Therefore, the fatigue level evaluation system according to the embodiment of the present invention can be applied to a wide range of age groups from the elderly to the lower age group.

  Moreover, according to the embodiment of the present invention, it is possible to easily make the subject understand whether or not there is a deviation between the objective fatigue state and the subjective fatigue state. Furthermore, according to the embodiment of the present invention, it is possible to allow the subject to easily understand the degree of deviation between the objective fatigue state and the subjective fatigue state. Therefore, according to the embodiment of the present invention, the subject can easily compare his or her objective fatigue state with the subjective fatigue state. In other words, it is possible to make the subject easily understand the relation between the objective fatigue state and the subjective fatigue state.

  Further, according to the embodiment of the present invention, it is possible to present the subject with fatigue level reduction advice in accordance with the objective fatigue state and the subjective fatigue state. Furthermore, it is possible to present the subject with a degree of fatigue reduction advice that matches the deviation between the objective fatigue state and the subjective fatigue state.

  In addition, according to the embodiment of the present invention, it is possible to determine the degree of fatigue of the subject using the objective degree of fatigue and the degree of subjective fatigue, so that fatigue (hidden fatigue) that the subject is not aware of Can be Specifically, even if the measurement result (second measurement result) of the subjective fatigue degree is "good", the measurement result (first measurement result) of the objective fatigue degree is "attention" or "attention". If it is, it can be judged as hidden fatigue. In the embodiment of the present invention, when the expression of the first face mark 10a is an expression worse than that of the second face mark 10b, it can be determined as being hidden fatigue. That is, when the sixth set of face marks 56, the seventh set of face marks 57, or the eighth set of face marks 58 is presented as a set of face marks, it can be determined as a cover fatigue. In other words, when the set of face marks is arranged in the fourth quadrant 24, it can be determined as hidden fatigue. Furthermore, according to the embodiment of the present invention, it is possible to present fatigue level reduction advice for reducing hidden fatigue. In addition, it can be judged only from the expression of the 1st face mark 10a and the 2nd face mark 10b whether it is hidden fatigue. Therefore, it is possible to easily determine whether the subject is hidden fatigue even if the subject is a low age group and an elderly person who can not read two-dimensional coordinates.

  In addition, as described in the second embodiment, by creating the history of the degree of fatigue, the subject can view changes in the state of objective fatigue and subjective fatigue of the subject (objective view). Therefore, for example, it is possible to improve the lifestyle according to the fatigue level reduction advice presented at the time of the previous measurement, and to evaluate the improvement of the lifestyle at the next time of the measurement. Alternatively, it is possible to incorporate an anti-fatigue period that implements measures according to the fatigue level reduction advice presented at the time of the previous measurement by the next measurement day, and evaluate the effect of the anti-fatigue period at the next measurement It becomes.
