Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of Patent Application No. 2019-206080, filed in Japan on November 14, 2019, the contents of which are incorporated herein by reference. [Technical Field]

[0002] The present disclosure relates to a subject registration device, a biological information measuring device, a subject registration program, a subject registration method, a subject registration system, and a computer-readable non-transitory storage medium. [Background technology]

[0003] For example, a device for measuring biological information using BIA (Bioelectrical Impedance Analysis), a so-called body composition analyzer, requires that information such as the subject's height, gender, and age be input in advance in order to calculate the subject's body composition.

[0004] In the body composition monitor disclosed in Patent Document 1 (JP 2016-114386 A), before a user measures their body composition, a setting mode is activated to perform initial settings for the body composition monitor, and the user is prompted to input user information including at least one of the user's age, sex, and height, and the input user information is stored in a memory unit. After inputting the user information, the user stands on the measurement platform of the body composition monitor and measures their body composition. The user information is then associated with the measured body composition. Summary of the Invention [Problem to be solved by the invention]

[0005] In the body composition monitor disclosed in Patent Document 1, the subject inputs information such as their age, sex, and height, and then measures their own body composition, and then performs the registration process of associating the input information with the measurement results. Although body composition monitors that allow the subject to register information about the subject in advance have been developed, even with such monitors, when the subject uses the monitor for the first time, the subject must select their own registration information and perform the operation of associating the registration information with the measurement results themselves.

[0006] Such operations of inputting the registration information of the subject and of associating the measurement results of the subject with the registration information can be difficult for elderly people and children, and in some cases they are unable to perform the operations themselves.

[0007] Therefore, the present disclosure aims to provide a subject registration device, a biometric information measuring device, a subject registration program, a subject registration method, a subject registration system, and a computer-readable non-transitory storage medium that can reduce the burden on the subject in matching registration information indicating the subject with measurement results. [Means for solving the problem]

[0008] A subject registration device according to one aspect of the present disclosure is a subject registration device that registers subjects who use a biometric information measuring device that measures biometric information, and includes: an estimation means that estimates biometric information for each registered subject based on registration information stored for one or more registered subjects who are measured using the biometric information measuring device; an identification means that identifies the registration information indicating the subject from the registration information for each registered subject based on the biometric information for each registered subject estimated by the estimation means and the measurement results of the subject using the biometric information measuring device; and an update means that updates the registration information identified by the identification means by correlating it with the measurement results of the subject.

[0009] According to this configuration, the registration information of the subject and the measurement results are automatically associated with each other without the subject having to perform any operation on the biological information measuring device to associate their own registration information with their own measurement results. Therefore, this configuration can reduce the burden on the subject in associating the registration information indicating the subject with the measurement results.

[0010] In the above-described subject registration device, the specifying means may rank the registration information in descending order of proximity of the estimated biological information to the measurement result.

[0011] According to this configuration, it is possible to more accurately associate the registration information indicating the subject with the measurement result.

[0012] In the above-mentioned measurement subject registration device, the identification means may identify the registration information indicating the measurement subject based on the estimated biometric information and the measurement results when the measurement subject is measured for the first time using the biometric information measuring device, and may identify the registration information indicating the measurement subject based on the current measurement results and the previous measurement results for each of the registration information when the measurement subject is measured for the second or subsequent time using the biometric information measuring device.

[0013] According to this configuration, the burden on the subject in associating the registered information indicating the subject with the measurement results can be reduced.

[0014] In the above-described subject registration device, the registration information may be information indicating age, sex, height, and weight.

[0015] According to this configuration, the biometric information of the registrant can be estimated more accurately.

[0016] The above-mentioned subject registration device may be provided with a notification means for notifying the registration information identified by the identification means, and an input receiving means for receiving input as to whether the registration information identified by the identification means is appropriate.

[0017] According to this configuration, it is possible to more accurately associate the registration information indicating the subject with the measurement result.

[0018] A biological information measuring device according to one aspect of the present disclosure includes the subject registration device described above.

[0019] A subject registration program according to one aspect of the present disclosure causes a computer of a subject registration device that registers subjects who use a biometric information measuring device that measures biometric information to function as: an estimation means that estimates biometric information for each registered subject based on registration information stored for one or more registered subjects who are measured using the biometric information measuring device; an identification means that identifies the registration information indicating the subject from the registration information for each registered subject based on the biometric information for each registered subject estimated by the estimation means and the measurement results of the subject using the biometric information measuring device; and an update means that updates the registration information identified by the identification means by correlating it with the measurement results of the subject.

[0020] A subject registration method according to one embodiment of the present disclosure is a subject registration method for registering subjects who use a biometric information measuring device that measures biometric information, and includes the following steps: a first step of estimating biometric information for each registered subject based on registration information stored for one or more registered subjects who are measured using the biometric information measuring device; a second step of identifying the registration information indicating the subject from the registration information for each registered subject based on the biometric information for each registered subject estimated in the first step and the measurement results of the subject using the biometric information measuring device; and a third step of updating the registration information identified in the second step by correlating it with the measurement results of the subject. [Effects of the Invention]

[0021] According to the present disclosure, it is possible to reduce the burden on the subject in associating the registration information indicating the subject with the measurement results. [Brief explanation of the drawings]

[0023] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the embodiments described below are examples of how the present disclosure may be implemented, and the present disclosure is not limited to the specific configurations described below. When implementing the present disclosure, specific configurations according to the embodiments may be appropriately adopted.

[0024] 1 is a schematic diagram of a body composition monitor 10 according to the present embodiment. The body composition monitor 10 measures biological information such as the subject's weight and body composition based on bioelectrical impedance. The body composition monitor 10 according to the present embodiment is installed in a house, for example, and used by the family members living in the house.

[0025] Body composition monitor 10 of this embodiment is provided with platform 32 on which the subject stands, right handgrip 33R, and left handgrip 33L in main body 30. The subject stands barefoot on platform 32 and grasps right handgrip 33R with his right hand and left handgrip 33L with his left hand to measure his body composition.

[0026] Main body 30 includes platform 32, right handgrip 33R, and left handgrip 33L, as well as body composition measurement unit 31 and weight measurement unit 34. Platform 32 includes right foot current-carrying electrode 321R, right foot measurement electrode 322R, left foot current-carrying electrode 321L, and left foot measurement electrode 322L. Right handgrip 33R includes right-hand current-carrying electrode 331R and right-hand measurement electrode 332R, and left handgrip 33L includes left-hand current-carrying electrode 331L and left-hand measurement electrode 332L.

[0027] The weight measurement unit 34 is equipped with a load cell for measuring weight. The load cell is composed of a strain element made of a metal member that deforms in response to a load, and a strain gauge attached to the strain element. When the person to be measured stands on the platform 32, the load of the person to be measured causes the strain element of the load cell to bend, causing the strain gauge to expand and contract. The resistance value (output value) of the strain gauge changes in response to this expansion and contraction. The body composition measurement unit 31 calculates weight from the difference between the output value of the load cell when no load is applied (zero point) and the output value when a load is applied. The configuration for measuring weight using a load cell may be the same as that of a general weight scale.

[0028] The body composition measurement unit 31 has a current supply function that passes a weak current of a predetermined frequency from each current-carrying electrode to a predetermined part of the subject's body, a potential difference measurement function that measures the potential difference generated in the current path, and a bioimpedance calculation function that calculates the bioimpedance of the subject's entire body and each body part based on the values ​​of such current and potential difference.

[0029] For example, age, sex, and height are input as information (registered information) about the subject to body composition measurement unit 31. This registered information is stored in registered information storage unit 40, which will be described later.

[0030] Measurement of the bioelectrical impedance of the subject's whole body and each body part by the body composition measurement unit 31 is carried out, for example, as follows. (1) When measuring the bioimpedance of the whole body, current is supplied using the left hand current-carrying electrode 331L and the left foot current-carrying electrode 321L, and the potential difference is measured between the left hand measurement electrode 332L in contact with the left hand and the left foot measurement electrode 322L in contact with the left foot in the current path that flows through the left hand, left arm, chest, abdomen, left leg, and left foot. (2) When measuring the bioimpedance of the right leg, current is supplied using the right hand current-carrying electrode 331R and the right foot current-carrying electrode 321R, and the potential difference between the left foot measurement electrode 322L in contact with the left foot and the right foot measurement electrode 322R in contact with the right foot is measured along the current path that flows through the right hand, right arm, chest, abdomen, right leg, and right foot. (3) When measuring the bioimpedance of the left leg, current is supplied using the left hand current-carrying electrode 331L and the left foot current-carrying electrode 321L, and the potential difference between the left foot measurement electrode 322L in contact with the left foot and the right foot measurement electrode 322R in contact with the right foot is measured along the current path that flows through the left hand, left arm, chest, abdomen, left leg, and left foot. (4) When measuring the bioimpedance of the right arm, current is supplied using the right hand current-carrying electrode 331R and the right foot current-carrying electrode 321R, and the potential difference between the left hand measurement electrode 332L in contact with the left hand and the right hand measurement electrode 332R in contact with the right hand is measured along the current path that flows through the right hand, right arm, chest, abdomen, right leg, and right foot. (5) When measuring the bioimpedance of the left arm, current is supplied using the left hand current-carrying electrode 331L and the left foot current-carrying electrode 321L, and the potential difference between the left hand measurement electrode 332L in contact with the left hand and the right hand measurement electrode 332R in contact with the right hand is measured along the current path that flows through the left hand, left arm, chest, abdomen, left leg, and left foot.

[0031] The body composition measurement unit 31 calculates body composition measurements for the whole body and each body part by applying a predetermined regression equation to the subject's registered information (age, sex, height), the weight measured by the weight measurement unit 34, and each calculated bioimpedance. The body composition measurement unit 31 calculates the body composition measurements, such as fat percentage, fat mass, lean mass, muscle mass, visceral fat mass, visceral fat level, visceral fat area, subcutaneous fat mass, basal metabolic rate, bone mass, total body water percentage, BMI, intracellular fluid volume, and extracellular fluid volume. The configuration for calculating the body composition measurements can also be the same as that of a general body composition monitor.

[0032] Furthermore, the body composition monitor 10 includes a touch panel display 20 and a user registration unit 22.

[0033] Touch panel display 20 includes a display panel such as a liquid crystal display panel and a touch sensor integrated with the display panel for receiving touch input. Measurement results from body composition monitor 10 and information related to user registration, which will be described in detail later, are displayed on touch panel display 20. Note that instead of touch panel display 20, a display panel and an input device such as a button or switch independent of the display panel may be provided.

[0034] The user registration unit 22 has a user registration function for registering information about the person being measured (hereinafter also referred to as "user") who uses the body composition monitor 10, and is composed of individual hardware such as a computing device (computer) or an ASIC (Application Specific Integrated Circuit), and a storage medium.

[0035] Furthermore, the body composition monitor 10 may have a function of communicating with other information processing devices such as a server.

[0036] In the body composition monitor 10 of this embodiment, registration information is input for one or more registered persons who will use the body composition monitor 10 for measurements, and the registration information is stored in the user registration unit 22. In this embodiment, the registered persons are, for example, the purchaser of the body composition monitor 10 and their family members, and each individual constituting the family (e.g., father, mother, son, daughter, etc.). Identification information such as father, mother, eldest son, eldest daughter, or name is added to each piece of registration information so that the user can identify each piece of registration information.

[0037] The registration information is information that can be used to estimate the biometric information (e.g., resistance, reactance, and impedance) of a registered user, and is, for example, information indicating the age, sex, height, and weight of each user. The registration information only needs to include at least age and sex, and does not necessarily need to include height or weight. The registration information can be modified after it is entered.

[0038] Furthermore, instead of directly inputting age, gender, height, and weight, information that can estimate these may be input as registration information. For example, instead of height and weight, a value that can determine the user's body size, such as clothing size, may be input as registration information. If clothing size is input, height and weight are estimated from the input size. Furthermore, even if gender is not input as registration information, if attributes of the user as a family member (e.g., father, mother, son, daughter, etc.) are input, the user's gender may be identified from the attributes, or if the user's name is included in the registration information, gender may be estimated from the input name.

[0039] Furthermore, instead of height and weight, general values ​​estimated based on age and gender (average height and weight for each age and gender) may be automatically input as registration information. Also, body shape (thin, normal, obese, muscular, etc.) and shoe size may be input as indicators that can estimate body composition.

[0040] In this embodiment, as an example, when a purchaser applies for purchase of body composition monitor 10 at a store or via the Internet, the purchaser notifies the seller of the information of the registrant of body composition monitor 10, and the seller enters the information into body composition monitor 10. Here, input includes not only a person directly performing an input operation on body composition monitor 10, but also information pre-stored in another information processing device (server) being downloaded to body composition monitor 10. However, this is not limiting, and the purchaser may also enter the registration information themselves after purchasing body composition monitor 10.

[0041] That is, user registration is performed in advance before the user performs a measurement, rather than when the user first performs a measurement using body composition monitor 10. User registration does not have to be performed by the user himself / herself, and it is also possible to perform user registration collectively for multiple users (e.g., family members) who may use body composition monitor 10 different from the user.

[0042] The body composition monitor 10 of this embodiment estimates the biological information of each registered person based on the stored registration information, and when the person to be measured takes a measurement for the first time, identifies the registered information of the person to be measured from the registered information of each registered person based on the estimated biological information and the measurement result of the person to be measured. The measurement result is then associated with the identified registered information and stored in the body composition monitor 10.

[0043] This allows the subject's registered information and measurement results to be automatically associated with each other without the subject having to perform the operation of associating their own registered information with their own measurement results. Therefore, body composition monitor 10 of this embodiment can reduce the burden on the subject of associating the registered information indicating the subject with the measurement results.

[0044] 2 is a functional block diagram showing the configuration of the user registration function of this embodiment. The user registration unit 22 includes a registration information storage unit 40, a biometric information estimation unit 42, a registration information identification unit 44, an identification result notification processing unit 46, and a registration information update unit 48.

[0045] The registration information storage unit 40 stores registration information for one or more registered individuals who undergo measurements using the body composition monitor 10. The registration information stored in the registration information storage unit 40 in this embodiment is, for example, the gender, age, height, and weight of each registered individual, and this information allows for more accurate estimation of the biometric information of each registered individual.

[0046] The biometric information estimation unit 42 estimates the biometric information of each enrolled person based on the enrollment information stored in the enrollment information storage unit 40. As an example, the biometric information estimation unit 42 of this embodiment estimates the impedance (hereinafter referred to as "estimated Z") and the ratio of reactance to resistance (hereinafter referred to as "estimated R / Xc") for each enrolled person based on the enrollment information (gender, age, height, and weight). The estimated biometric information is stored in the enrollment information storage unit 40 in association with each enrolled person. In the following description, the estimated biometric information will be referred to as estimated biometric information.

[0047] The registration information identification unit 44 identifies the registration information indicating the subject from the registration information for each registered person based on the estimated biological information for each registered person and the measurement results of the subject measured by the body composition monitor 10 (impedance (hereinafter referred to as "actually measured Z"), and the ratio of reactance to resistance (hereinafter referred to as "actually measured R / Xc")).

[0048] Here, Fig. 3 is a graph showing the relationship between estimated biological information values ​​and measurement results (estimation accuracy). Fig. 3(A) is a graph showing the relationship between estimated Z and actually measured Z, and Fig. 3(B) is a graph showing the relationship between estimated R / Xc and actually measured R / Xc.

[0049] The estimated Z and estimated R / Xc shown in Figures 3(A) and (B) are values ​​based on an estimation formula that uses the age, sex, height, and weight entered as registration information as variables. As shown in this figure, by comparing the estimated value with the actual measured value, the registration information corresponding to the subject can be identified.

[0050] The method for estimating estimated biometric information based on registered information is not particularly limited, but may be performed by regression analysis or the like.

[0051] Furthermore, the registered information identification unit 44 of this embodiment ranks the registered information in order of the proximity of the estimated biological information to the measurement result of the subject. On the other hand, even if the registered information is ranked, if a measurement result is determined not to match the estimated biological information of any of the registered information, the registered information identification unit 44 may treat the measurement result as a guest that is not associated with the registered information. Note that the touch panel display 20 may display a message indicating that the measurement result is being treated as a guest, or a message that accepts input from the subject as to whether the guest is appropriate. If it is determined that treating the measurement result as a guest is inappropriate, subsequent processing is performed based on the ranked registered information. Furthermore, the ranked registered information may be displayed on the touch panel display 20 regardless of whether the measurement result is being treated as a guest.

[0052] Furthermore, the registered information identification unit 44 of this embodiment identifies the registered information identifying the person being measured based on the estimated biometric information and the measurement results when the person being measured is taking a measurement for the first time using the body composition monitor 10, and identifies the registered information identifying the person being measured based on the current measurement results and previous measurement results for each registered information when the person being measured is taking a measurement for the second time or later using the body composition monitor 10.

[0053] The identification result notification processing unit 46 controls the touch panel display 20 to display the registration information identified by the registration information identification unit 44. On the touch panel display 20, as a display mode of the identified registration information, for example, identification information for identifying each piece of registration information, such as father, mother, eldest son, eldest daughter, or name, is displayed.

[0054] The touch panel display 20 then accepts an input indicating whether or not the registration information identified by the registration information identification unit 44 is appropriate as registration information identifying the subject. If the input indicates that the identified registration information is not appropriate for the subject, the identification result notification processing unit 46 causes the touch panel display 20 to display the next piece of registration information. The notification of the identified registration information may be made by voice. In this case, the subject inputs by voice whether or not the identified registration information is appropriate.

[0055] Furthermore, the identification result notification processing unit 46 may display a countdown on the touch panel display 20 together with the identified registered information, and if the subject does not input that the displayed registered information is “inappropriate” before the countdown reaches “0,” the displayed registered information may be deemed “appropriate.” This allows the subject to associate the registered information with their own measurement results without performing any operation.

[0056] The registration information update unit 48 updates the registration information identified by the registration information identification unit 44 by associating the measurement results of the subject with the registration information. The updated registration information is stored in the registration information update unit 48. The measurement results stored in association with the registration information include weight, actual measurement Z, actual measurement R / Xc, body composition measurement values ​​calculated based on these, and the measurement date and time.

[0057] FIG. 4 is a flowchart showing the flow of the user identification process executed by the user registration unit 22.

[0058] First, in step S100, the subject is measured using body composition monitor 10.

[0059] In the next step S102, the registration information identification unit 44 determines whether or not this is the first time that the subject has been measured using the body composition monitor 10. If the determination is affirmative, the process proceeds to step S108; if the determination is negative, the process proceeds to step S104.

[0060] For example, if all registered information has already been associated with measurement results, the registered information identifying unit 44 determines that this is not the first measurement for the subject. Furthermore, if there is registered information with a previous measurement result close to the current measurement result (weight, actual measurement Z, actual measurement R / Xc), the registered user corresponding to the registered information is the subject, and therefore the measurement is determined to be the second or subsequent measurement. On the other hand, for example, if there is no registered information associated with a measurement result, the registered information identifying unit 44 determines that this is the first measurement for the subject. Furthermore, if there is no registered information with a previous measurement result close to the current measurement result, it determines that the measurement is the subject's first.

[0061] Furthermore, in order to enable the registered information identification unit 44 to determine whether or not this is the first time that the subject is being measured, a button (hereinafter referred to as the "first measurement button") to be operated by the subject when taking the first measurement may be displayed on the touch panel display 20. In other words, when the first measurement button is operated by the subject, the registered information identification unit 44 determines that this is the first time that this subject is being measured. Note that the display of the first measurement button on the touch panel display 20 may cease when the first measurement result, etc. have been associated with all of the registered information.

[0062] In step S104, since this is the second or subsequent measurement for the subject, the registration information identification unit 44 identifies the registration information indicating the subject based on the current measurement result and the previous measurement results for each piece of registration information. Specifically, the registration information identification unit 44 sets the registration information corresponding to the subject to the registration information having the previous measurement result that is closest to the current measurement results of weight, actual measurement Z, and actual measurement R / Xc.

[0063] In the next step S106, body composition measurements are calculated based on the measurement results, and the process proceeds to step S118. Specifically, the body composition measurements for the whole body and each body part are calculated by applying a predetermined regression equation to the subject's biological information (age, sex, height) registered as registration information, the weight measured by weight measurement unit 34, and the actual measured Z and R / Xc.

[0064] In step S108, which is performed if it is determined in step S104 that this is the first measurement for the subject, the registered information identifying unit 44 identifies the registered information corresponding to the subject who has undergone the first measurement.

[0065] FIG. 5 is a flowchart showing the flow of the identification process executed in step S108.

[0066] First, in step S200, registered information is selected where the absolute difference between the weight of the measurement result and the weight of the registered information is within a predetermined range (primary selection). Note that registered information that has already been associated with a measurement result is excluded from the primary selection because the subject has been identified.

[0067] In the next step S202, from the initially selected registered information, registered information in which the absolute difference between the measurement result biometric information (actually measured Z, actual measured R / Xc) and the estimated biometric information (estimated Z, estimated R / Xc) is within a predetermined range is selected (secondary selection).

[0068] In the next step S204, the secondly selected registered information is ranked. This ranking is performed, for example, in descending order of the average value of the absolute difference between the weight and the biological information, such as first candidate, second candidate, etc. If there is only one secondly selected registered information, step S204 is omitted.

[0069] In the next step S110, the identification result notification processing unit 46 causes the touch panel display 20 to display the registered information that is determined to be the first candidate.

[0070] In the next step S112, the registration information identification unit 44 determines whether the subject has made an input indicating that the candidate displayed on the touch panel display 20 is appropriate, and if the determination is positive, the process proceeds to step S114, whereas if the determination is negative, the process proceeds to step S116.

[0071] In step S114, a body composition measurement value is calculated based on the measurement result, and the process proceeds to step S118.

[0072] In step S116, since the candidate displayed on touch panel display 20 is not appropriate, identification result notification processing unit 46 displays the next candidate registered information on touch panel display 20, and the process returns to step S112.

[0073] In step S118, the registration information update unit 48 associates the current measurement results (body weight, actual measured Z, actual measured R / Xc), body composition measurement values, and measurement date and time with the identified registration information and stores them in the registration information storage unit 40, and then terminates the registration information identification process.

[0074] Although the present disclosure has been described using the above-mentioned embodiments, the technical scope of the present disclosure is not limited to the scope described in the above-mentioned embodiments. Various modifications or improvements can be made to the above-mentioned embodiments without departing from the gist of the disclosure, and such modifications or improvements are also included in the technical scope of the present disclosure.

[0075] For example, in the above embodiment, a configuration has been described in which the user registration unit 22 is provided in the body composition monitor 10, but the present disclosure is not limited to this, and for example, the user registration unit 22 may be provided in an information processing device such as a server that can communicate with the body composition monitor 10. In this configuration, the registration information is stored in the server, the measurement results of the body composition monitor 10 are transmitted to the server, and the body composition monitor 10 receives the processing results by the server. Furthermore, although the body composition monitor 10 includes the user registration unit 22, the server may include the registration information storage unit 40.

[0076] As another embodiment, a subject registration system 100 may be configured as shown in Fig. 6. The subject registration system 100 includes a body composition monitor 10, a server 102, and a smartphone 104. The server 102 stores registration information for one or more registrants who will be measured using the body composition monitor 10. The smartphone 104 is a portable information processing device that acquires the registration information from the server 102 and acquires biological information from the body composition monitor 10. Note that this information processing device is not limited to the smartphone 104, and may be another information processing device such as a tablet terminal device or a laptop computer.

[0077] The smartphone 104 includes a biometric information estimation unit 42, a registration information identification unit 44, and a registration information update unit 48. In this embodiment, the biometric information estimation unit 42, the registration information identification unit 44, and the registration information update unit 48 are executed by application software (hereinafter referred to as a "smartphone app") installed on the smartphone 104.

[0078] The biometric information estimation unit 42 included in the smartphone 104 estimates the biometric information of each enrolled person based on the enrollment information acquired from the server 102.

[0079] The registration information identification unit 44 provided in the smartphone 104 identifies the registration information indicating the subject from the registration information for each registered person based on the biometric information for each registered person estimated by the biometric information estimation unit 42 and the measurement results of the subject by the body composition monitor 10.

[0080] The registration information update unit 48 included in the smartphone 104 associates the measurement results of the subject with the registration information identified by the registration information identification unit 44, and updates the registration information stored in the server 102. Alternatively, the registration information update unit 48 included in the smartphone 104 may associate the measurement results of the subject with the registration information identified by the registration information identification unit 44, update the registration information, and send the updated registration information to the body composition monitor 10. The body composition monitor 10 registers the user based on the updated registration information received from the smartphone 104. Furthermore, the registration information update unit 48 included in the smartphone 104 may send the updated registration information to the body composition monitor 10 and the server 102.

[0081] According to the subject registration system 100, the smartphone 104 acquires registration information stored in the server 102, and also acquires the weight, impedance, and the like measured by the body composition scale 10. Then, using the weight and impedance acquired from the body composition scale 10 and the registration information acquired from the server 102, the smartphone 104 identifies which registration information the user measured by the body composition scale 10 corresponds to. The smartphone 104 then associates the user's new measurement results with the identified registration information and updates the registration information stored in the server 102. Alternatively, the smartphone 104 associates the user's new measurement results with the identified registration information and updates the registration information stored in the body composition scale 10. Alternatively, the smartphone 104 associates the user's new measurement results with the identified registration information and updates the registration information stored in the server 102 and the body composition scale 10.

[0082] Next, an example of registration processing using the smartphone 104 will be described with reference to Fig. 7. In this embodiment, the user uploads registration information (hereinafter referred to as "pre-registration information") to the server 102 in advance.

[0083] For example, when a user purchases clothes using online shopping or the like, the pre-registration information is uploaded by entering the pre-registration information on a shopping site and transmitted to server 102. The pre-registration information may include registration information of multiple registrants, such as the user's family members. For example, if pre-registration information including registration information of the user's family members or the like is already stored in server 102, this pre-registration information is read from server 102, and the user's registration information is added to this pre-registration information.

[0084] The registration process shown in FIG. 7 is executed when the user measures his / her own biological information using the body composition monitor 10.

[0085] First, in step 300 , pre-registration information is downloaded from the server 102 to the smartphone 104 via a smartphone app installed on the smartphone 104 .

[0086] This download is performed, for example, by inputting into the smartphone app identification information (password, QR code (registered trademark), authentication code, etc.) issued when the advance information is registered on the server 102. In addition, the smartphone app user may not be able to check the content of the downloaded advance registration information. This is because, for example, some users may have reasons for not wanting to show their weight to even their family members.

[0087] In addition, since the user does not need to download to the smartphone 104 the registration information of other users who are already registered but are included in the pre-registration information, the registration information of other users who are already registered on the body composition analyzer 10 may not be subject to downloading.

[0088] In the next step 302, the smartphone app (biometric information estimation unit 42) estimates biometric information such as the impedance of the user based on the pre-registration information.

[0089] In the next step 304 , the user uses the body composition monitor 10 to measure their own biometric information such as impedance and weight, and the biometric information measured by the body composition monitor 10 is transmitted to the smartphone 104 .

[0090] In the next step 306, the smartphone app (registration information identification unit 44) compares the biometric information estimated by the smartphone app with the measurement results of the biometric information received from the body composition scale 10, and identifies the user's registration information included in the pre-registration information.

[0091] In the next step 308, the smartphone app (registration information update unit 48) transmits the registration information of the identified user to the body composition monitor 10, and the body composition monitor 10 associates the registration information with the measurement results to complete the registration of the user. Note that the smartphone app may also update the registration information stored in the server 102 by associating it with the measurement results of the body composition monitor 10.

[0092] 6 and 7 is not limited to the above. For example, in the embodiment of the subject registration system 100 described above, the smartphone 104 includes all of the biological information estimating unit 42, the registered information specifying unit 44, and the registered information updating unit 48, but this is not limiting. The server 102 or the body composition monitor 10 may include at least one of the biological information estimating unit 42, the registered information specifying unit 44, and the registered information updating unit 48. For example, the server 102 may include the biological information estimating unit 42, the smartphone 104 may include the registered information specifying unit 44, and the body composition monitor 10 may include the registered information updating unit 48.

[0093] Furthermore, the above-described server 102 does not necessarily have to be included as a component of the subject registration system 100. In this case, at least one of the smartphone 104 and the body composition monitor 10 may be provided with a registration information storage unit 40, and for example, the pre-registration information acquired by the smartphone 104 in the above-described step 300 may be used as registration information either directly or after processing, and this registration information may be updated in step 308.
