The evaluation system 100 can be caused to function as various functional blocks or various steps described later.

  In FIG. 1, the evaluation system 100 (for example, the processing unit 110) is connected to a terminal 160 via a communication network 150 so that data can be transmitted and received. The communication network 150 can include not only a communication network such as the Internet but also a communication network via a local area network (LAN) or other communication lines.

  The terminal 160 is a device that allows a subject to measure and / or input biometric information and transmit the measured and / or input data over the communication network 150. As illustrated in FIG. 1, a plurality of terminals 160-1 to 160-n may be connected to a communication network, and the evaluation system 100 may be connected so as to be able to transmit and receive data to and from the plurality of terminals 160-1 to 160-n.

  As the terminal 160, for example, a known computer provided in a hospital, a fitness gym, or the like can be applied. Specifically, the terminal 160 is a data input unit for inputting information related to the subject including age and sex. 162, a biological information measuring unit 164 for measuring the biological information of the subject, a display unit 166 for displaying various information, and the like. Alternatively, the terminal 160 may be a general-purpose computer including a data input unit 162 and a display unit 166 or a mobile terminal such as a mobile phone. In this case, the terminal 160 may input measurement data of biological information obtained from a biological information measuring device (not shown) separate from the terminal.

  Next, the configuration of the evaluation system 100 will be specifically described.

  The processing unit 110 of the evaluation system 100 mainly includes a measurement data acquisition unit 112 that acquires measurement data of a subject, a standardized data generation unit 114 that standardizes the measurement data and generates standardized data, and normalizes the standardized data. A normalized data generation unit 116 that generates normalized data, an evaluation index data generation unit 118 that calculates normalized index data to generate evaluation index data, and a processing result that provides a result obtained by any of the above processes A providing unit 120 is included. In addition, the evaluation system 100 includes a reference data storage unit 130 that stores reference data that is referred to in the processing of the processing unit 110, and an information storage unit 140 that stores information on the exercise form and / or advice form. Is provided. Each component in the processing unit 110 is connected to the reference data storage unit 130 and the information storage unit 140 so as to be able to transmit and receive data, thereby storing necessary data processed by the processing unit 110 in the storage unit. Alternatively, the data can be read from the storage unit.

  The measurement data acquisition unit 112 acquires measurement data for a plurality of items of biological information for the subject. In this case, a plurality of measurement data for each item for one subject is acquired as one set.

  As shown in FIG. 2, the items of biometric information include “chest circumference / abdominal circumference”, “hip / abdominal circumference” and “thigh circumference / abdominal circumference” belonging to the body dimension classification, and “body temperature” belonging to the body activity classification. , “Heart rate”, “Maximum blood pressure” and “Minimum blood pressure”, “BMI (Body Mass Index)” belonging to the classification of body composition, “Body fat percentage” and “basal metabolism / body surface area”, and exercise capacity "Sitting on a chair" belonging to the classification (repeating the sitting and standing motions of the chair a predetermined number of times), "Reaction time" (time from when the object is displayed until it recognizes it and taking action), "One eye with closed eyes “Standing”, “grip strength”, “upper body raising”, and the like. However, the item content and the number of items of the biometric information are not limited to the above example, and any item content and the number of items may be used as long as they are widely biometric information for the subject. In addition, the item of biometric information is a component obtained by converting a biometric information element in association with another element (for example, “BMI” in which height is converted in association with weight) in order to facilitate comparison with other subjects. Alternatively, it may be an element of biological information itself (for example, “height” and “weight”). In the latter case, the measurement data for the elements of the biological information acquired by the measurement data acquisition unit 112 may be associated with the measurement data for other elements and the subsequent processing may be performed.

  As shown in FIG. 2, each item of biological information can be classified into three item groups due to the nature. That is, the first item group that is better when the value of the measurement data is better, the second item group that is better when the value of the measurement data is closer to the average, and the third item that is better when the value of the measurement data is smaller. It is a group of items. In the example shown in FIG. 2, the first group of items is “chest circumference / abdominal circumference”, “hip / abdominal circumference”, “thigh circumference / abdominal circumference”, “basal metabolism / body surface area”, “single-leg standing with eyes closed”, “grip strength”, and The second item group includes “body temperature”, “heart rate”, “maximum blood pressure” and “minimum blood pressure”, and the third item group includes “BMI” and “body fat percentage”. Includes "sitting on a chair" and "reaction time". Information regarding the correspondence between the items of biometric information and the above-described item groups may be stored in the reference data storage unit 130 in advance, or may be determined by the processing unit 110 (standardized data generation unit 114) according to a predetermined agreement. Good.

  The reference data storage unit 130 stores reference data for the processing unit 110 to refer to. The reference data storage unit 130 includes an average and standard deviation database 132 for a plurality of items that is databased based on biological information of a plurality of subjects. This database 132 has an average and standard deviation for a plurality of items for each classification based on age, gender, etc., and is necessary for the classification of the subject of the measurement data acquired by the measurement data acquisition unit 112. Data is provided to the processing unit 110. In addition, the reference data storage unit 130 includes a correlation database 134 in which a correlation indicating the magnitude of the relationship between a plurality of items of biometric information is stored in a database. The correlation coefficient data stored in the database 134 may indicate the relationship with respect to all other items in one item.

  The reference data storage unit 130 may be a storage medium provided outside the server as the processing unit 110, or may be provided inside the server as the processing unit 110. In addition to the above-described database, the reference data storage unit 130 may store various databases (formulas and functions shown below) necessary for the processing unit 110 to process.

The standardized data generation unit 114 generates standardized data for a plurality of items of biological information by standardizing the measurement data acquired by the measurement data acquisition unit 112 based on the reference data. Specifically, the standardized data generation unit 114 reads the reference data corresponding to the measurement data acquired by the measurement data acquisition unit 112, that is, data related to the average and standard deviation from the reference data storage unit 130, and based on the following formula: Generate standardized data.

  Here, in the above formula, is the measurement data for the i-th item (in the case of FIG. 2, i = 1, 2,..., 15), is the average data for the i-th item, and The standard deviation data for the i item is the standardized data for the i-th item. In this way, by generating standardized data from the measurement data, the position of the subject subject in the distribution of the entire subject is determined as to the position of each of the subjects for each item. Can be standardized so that they can be compared on the same basis.

The normalized data generation unit 116 generates normalized data for a plurality of items of biological information by normalizing the standardized data generated by the standardized data generation unit 114 between a plurality of items. That is, the standardized data is converted according to a predetermined function so that each of a plurality of items of biometric information can be compared on the same basis. Specifically, the normalized data generation unit 116 determines whether the item of the standardized data corresponds to the first to third item groups of the standardized data, and the function corresponding to the first item group ( 1) Decide which of the function (2) corresponding to the second item group and the function (3) corresponding to the third item group to generate the normalized data, and generate the normalized data. Examples of functions (1) to (3) are as follows.

Here, k _i of the above functions is a coefficient for the i-th item, and q _i is normalized data for the i-th item. For the coefficient k _i , the same value (for example, k _i = 1) may be applied to a plurality of items of biological information, and the value can be determined based on the health condition of the subject. Further, the coefficient k _i may be changed depending on the item of the biometric information. For example, a different value may be applied for each item based on the magnitude of the degree of relationship with the finally determined reference.

FIG. 3 is a diagram showing graphs of the functions (1) to (3) when k _i = 1. Specifically, FIG. 3A is a graph of the function (1), and FIG. The graph of the function (2) and FIG. 3C show the graph of the function (3). As can be seen from FIG. 3, in the first item group, q _i increases so that the value of the measurement data (the same applies to the standardized data) is better (ie, healthier), while the third item group In q, q _i increases so that the smaller the value of the measurement data (the same applies to the standardized data), the better. For the second item group, q _i increases so that the value of the measurement data (the same applies to the standardized data) is closer to the average. Further, according to the configuration of the functions (1) to (3), the value of the normalized data q _i is asymptotic when the value of the measurement data (same for standardized data) is too far from the standard value. Saturated. As a result, even if the measurement data is too far apart from the standard value in any one item, the value of the normalized data q _i does not fluctuate greatly, that is, it does not significantly affect the health level. More accurate results can be obtained.

The evaluation index data generation unit 118 generates evaluation index data that is a comprehensive index of a plurality of items of the biological information of the subject from the normalized data generated by the normalized data generation unit 116. That is, the evaluation index data generation unit 118, as shown in the following equation, weighted data R _i weighted for each item of biometric information from correlation coefficient data R _ij indicating the relationship between a plurality of items of biometric information. Is normalized between the plurality of items so that the weighting data R _i can be compared on the same basis in each of the plurality of items, and the normalized weighting data r _i (0 ≦ r _i ≦ 1) is calculated. And the sum of the values obtained by multiplying the normalized weight data r _i and the normalized data q _i in each of the plurality of items of the biometric information in the plurality of items, thereby obtaining the evaluation index data α (0 ≦ 0). α ≦ 1) is calculated.

Here, the correlation coefficient data R _ij is a correlation coefficient between the i-th item and the j-th item, and is a coefficient indicating how strong the relationship is between each item. Such correlation coefficient data can be created in advance based on the biological information of a plurality of subjects, and can be stored in advance in the reference data storage unit 130, for example.

Further, the weighting data R _i is weighted according to the magnitude of the degree of relationship with the finally determined standard, for example, in order to calculate evaluation index data more comprehensively for a plurality of items of biological information.

  In the evaluation index data α obtained in this way, in theory, when the measured value = average value in all items, α = 0.5, and the measured value of any item is good Α> 0.5, while α <0.5 if not favorable.

  The processing result providing unit 120 provides at least a part of the processing results among the standardized data, the normalized data, and the evaluation index data obtained by each configuration of the processing unit 110 described above. The processing result providing unit 120 may provide the processing result to the display or printer of the evaluation system 100, or may be configured to provide the processing result to the terminal 160, that is, the subject via the communication network 150. .

  Further, the processing result providing unit 120 provides predetermined information stored in the information storage unit 140 based on the processing result of the processing unit 110 described above. That is, the information storage unit 140 stores the exercise database 142 and the advice database 144 as information to be provided to the subject, and the processing result providing unit 120 includes at least the standardized data, the normalized data, and the evaluation index data. Based on some results, predetermined information stored in each database 142, 144 is provided. The exercise database 142 stores various information such as exercise content, exercise method, exercise amount (number of exercises and frequency) for maintaining or improving the health condition of the subject, and the advice database 144 similarly. For this purpose, various kinds of information such as advice contents are stored. In addition, about the display of the result by the process result provision part 120, FIG.5 and FIG.6 mentioned later and description regarding it can be referred.

  According to the biometric information evaluation system according to the present embodiment, a comprehensive evaluation index based on a certain standard can be generated from measurement data on a plurality of items related to the biometric information of a subject. As a result, the measurement data of multiple items can be judged comprehensively based on what has traditionally been determined only by whether it is healthy or if there is any risk, and to what level You can evaluate whether there is. Therefore, a system capable of more objectively and accurately evaluating the biological information of the subject can be provided.

  In the above embodiment, the configuration in which the evaluation system 100 is connected to the terminal 160 via the communication network 150 has been described. However, the evaluation system 100 and the terminal 160 can be connected to each other without using the communication network 150. Data can be transmitted and received between the two. In this case, the terminal 160 may be a computer or a measurement device separate from the evaluation system 100, or may be configured to be incorporated in the evaluation system 100.

2. About the evaluation method of biometric information Next, with reference to FIGS. 1-4, the evaluation method of the biometric information which concerns on one Embodiment of this invention is demonstrated. Here, FIG. 4 is a diagram illustrating a flowchart regarding the biological information evaluation method according to the present embodiment. The biological information evaluation method according to the present embodiment can be performed using the evaluation system 100 described in the above-mentioned section “About the biological information evaluation system”. Note that the order of steps described below (including not only the steps indicated by the reference numerals shown in FIG. 4 but also partial steps thereof) can be arbitrarily changed within a range that does not contradict the processing contents. Or in parallel.

  First, the evaluation system 100 measures and / or measures input data of personal information such as name, gender, and age, and measurement data for a plurality of items of biological information to the terminal 160 (that is, the display unit 166) via the communication network 150. Or prompt for input. On the other hand, the subject inputs such personal information and measures and / or inputs measurement data based on the display on the terminal 160. Data input to the terminal 160 is transmitted to the evaluation system 100 via the communication network 150. Thus, for example, in the processing unit 110 (specifically, the measurement data acquisition unit 112) of the evaluation system 100, measurement data for a plurality of items of the biological information of the subject is acquired (S101). The acquired measurement data may be temporarily stored in the reference data storage unit 130 until used in subsequent processing.

You may store in a memory | storage part (for example, reference data memory | storage part). As a result, biometric information samples as reference data can be accumulated, so that more objective and accurate evaluation index data can be generated.

Specifically, based on the classification of items determined in advance, each of the plurality of items of biometric information is identified as one of the first to third item group (see FIG. 2), Normalized data is generated using a function (see FIG. 3) corresponding to the specified item group. Such normalization processing can be performed by the normalization data generation unit 116, and the specific contents of the processing are as already described in the configuration of the normalization data generation unit 116.

  Next, the evaluation data of the biological information of the subject is generated by calculating the normalized data based on the correlation coefficient data indicating the relationship between the plurality of items (S107). Such calculation processing can be performed by the evaluation index data generation unit 118. The evaluation index data generation unit 118 reads the normalized data from the normalized data generation unit 116 or the reference data storage unit 130, while reading the correlation coefficient data from the correlation coefficient database 134 of the reference data storage unit 130. Calculate based on the data. Specifically, the processing described in the configuration of the evaluation index data generation unit 118 can be applied. Thus, the generated evaluation index data may be stored in the reference data storage unit 130.

  Thereafter, as required, information is provided based on at least a part of the processing results of the standardized data, normalized data, and evaluation index data (S109). Such processing can be performed by the processing result providing unit 120. The processing result providing unit 120 reads the standardized data, normalized data, and evaluation index data generated in each of the above steps from the processing unit 110 that generated the data or the reference data storage unit 130 that is temporarily stored. Information related to the read data or information related thereto can be transmitted to the terminal 160 via the communication network 150.
