[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-339671 [Patent Document 2] Japanese Patent Application Publication No. 11-244252 [Patent Document 3] Special Publication No. 2014-507213 [Patent Document 4] Japanese Patent Application Laid-Open No. 2002-238870 Summary of the Invention [Problem to be solved by the invention]
[0004] Typical body composition scales have a load cell and electrodes that contact the human body. These devices measure weight and bioimpedance, displaying results related to weight and various body composition parameters. These measurements take only a few seconds, and body movements such as head movements during the measurement to check the measurement progress displayed at the user's feet have little effect on the results. On the other hand, when a body composition scale is equipped with features such as BCG (ballistocardiogram) measurements from the load cell and IPG (impedance pulse wave) measurements from the electrodes to provide the user with cardiovascular status information, body movements caused by head or arm movements during measurement significantly affect the results, resulting in longer measurement times or even measurement errors requiring remeasurements. Furthermore, body composition scales typically collect a series of data simultaneously, with all measurement results displayed sequentially after a specified measurement time has elapsed. Therefore, the more measurement items are added, the longer the measurement time, including the time required to display the results. However, in cases where a body composition scale is shared by a family, the only item being monitored may be weight, and the measurement items may be limited to weight.
[0005] In Patent Document 1, in the first action, the subject steps onto the scale, places their left foot on a left foot electrode attached to a footboard, and places their right foot on the same footboard as the left foot, and their weight is measured. In the second action, the subject spreads their legs and moves their right foot from the footboard to a right foot electrode attached to a support stand, and impedance is measured (see paragraphs 0013, 0014, etc. of Patent Document 1). Therefore, in Patent Document 1, the subject needs to move their feet significantly during the measurement, and the measurement cannot be completed with their feet in the same position as when they stepped onto the scale, which reduces usability. In Patent Document 2, the standard configuration is one in which two electrode units are placed on both the left and right sides of the weight measurement unit, and the subject steps onto the central weight measurement unit to capture weight data, and the subject steps onto the two electrode units to capture impedance data (see paragraph 0025 of Patent Document 2). Therefore, in Patent Document 2, the subject needs to move their feet significantly during the measurement, and the measurement cannot be completed with their feet in the same position as when they stepped onto the weight measurement unit or electrode unit, which reduces usability. For example, when a body composition monitor is provided with a dedicated key for weight as in Patent Document 4, an additional dedicated key for weight is required, and key operation before measurement is troublesome, reducing usability.
[0006] The present invention has been made in view of the above circumstances, and aims to improve usability in measuring biological information. [Means for solving the problem]

The measurement unit performs different operations depending on the direction in which the subject is facing when the subject stands on the placement surface of the biological information measurement device, thereby improving usability in measuring biological information.
[0010] The detection unit detects the position of the subject's feet on the placement surface, thereby detecting the riding style selected by the subject. The measurement unit operates differently depending on the position of the subject's feet on the placement surface of the biological information measurement device. The measurement unit performs different operations depending on the position of the subject's feet on the placement surface of the biological information measurement device, thereby improving usability in measuring biological information.
[0011] The time at which the measurement unit measures the biological information varies depending on the riding style detected by the detection unit. The measurement items that the measurement unit measures the biological information vary depending on the riding style detected by the detection unit. The recording target of the measurement results of the biological information varies depending on the riding style detected by the detection unit.
[0012] The biological information measuring device includes first electrodes that can be brought into contact with the sole of one of the feet of the subject, and second electrodes that can be brought into contact with the sole of the other of the feet of the subject, and the number of the first electrodes is different from the number of the second electrodes, thereby guiding the subject to consciously place one or the other of their feet on the placing surface of the biological information measuring device.
[0013] The biological information measuring device includes a first electrode that can be brought into contact with the sole of one of the feet of the subject, and a second electrode that can be brought into contact with the sole of the other of the feet of the subject, and the shape of the first electrode and the shape of the second electrode are different. The subject can be guided to consciously place one or the other of his or her feet on the placement surface of the measurement device.
[0014] The present invention can also be understood as a biological information measurement method in which a computer executes at least a part of the above-mentioned processes, a biological information measurement method including at least a part of the above-mentioned processes, a program for causing a computer to execute at least a part of the above-mentioned processes, or a computer-readable recording medium on which such a program is non-temporarily recorded.

As shown in FIG. 3, load cells 31 to 34 are arranged on the rear side of the biological information measurement device 1. The load cells 31 to 34 are respectively arranged near the four corners on the rear side of the biological information measurement device 1. Taking into consideration the influence of the body movement of the subject, the load cells 31 to 34 are arranged so that a load is applied evenly to each of the load cells 31 to 34.

[0027] The temperature measurement unit 25 measures the temperature of the soles of the feet of the person being measured who is standing on the surface of the biological information measurement device 1. The temperature measurement unit 25 has a temperature sensor. The temperature sensor is placed on the surface of the biological information measurement device 1. The temperature sensor may be placed in the vicinity of the electrodes 12 to 15.
[0028] The communication unit 26 is an interface for performing wired or wireless communication. The communication unit 26 communicates with an information processing device of the person being measured. The information processing device is, for example, a mobile terminal, a smartphone, a tablet terminal, a personal computer, etc.
[0029] The memory unit 27 stores information and data. The memory unit 27 may have at least one of a memory such as RAM and a storage. The storage may be a non-volatile storage device such as a ROM or a flash memory. The memory unit 27 stores various information such as the subject's personal data and the measurement results of the biological information measuring device 1. The personal data is used when calculating the subject's body composition. The personal data includes at least the subject's height and weight, and may further include the subject's age, gender, and other information. The subject's weight is measured when the subject stands on the surface of the biological information measuring device 1. The subject operates the operating unit 11, and the subject's height, age, gender, and other information are input to the biological information measuring device 1.
[0030] 5 is a block diagram showing the functional configuration of the control unit 20. The control unit 20 includes a detection unit 41 and a measurement unit 42. The detection unit 41 includes an order detection unit 51, a direction detection unit 52, and a placement detection unit 53. The measurement unit 42 includes a weight measurement unit 54, a body composition measurement unit 55, a standing balance measurement unit 56, and a cardiovascular measurement unit 57.
[0031] The detection unit 41 detects the riding style selected by the subject from among multiple riding styles on the surface of the biological information measuring device 1. The measurement unit 42 measures the biological information of the subject. The order detection unit 51 detects the order in which the subject's left foot and right foot place on the surface of the biological information measuring device 1 based on measurement values output from at least one of the electrode unit 21, the first sensor unit 23, and the second sensor unit 24, thereby detecting the riding style selected by the subject.
[0032] The direction detection unit 52 detects the riding style selected by the subject by detecting the direction the subject is facing when standing on the surface of the biological information measuring device 1, based on measurement values output from at least one of the electrode unit 21, the first sensor unit 23, and the second sensor unit 24. The placement detection unit 53 detects the placement of the subject's feet on the surface of the biological information measuring device 1, based on measurement values output from at least one of the electrode unit 21 and the first sensor unit 23, thereby detecting the riding style selected by the subject.
[0033] The weight measurement unit 54 measures the weight of the subject standing on the surface of the biological information measurement device 1 based on the measurement value output from the second sensor unit 24. The body composition measurement unit 55 measures the body composition of the subject standing on the surface of the biological information measurement device 1 based on the subject's personal data, the bioimpedance output from the impedance measurement unit 22, and the subject's weight according to a predetermined algorithm. Body composition is an index indicating the proportion or amount of components that make up the body. Examples of body composition include, but are not limited to, body fat percentage, visceral fat level, skeletal muscle percentage, basal metabolic rate, body age, BMI, muscle percentage, muscle mass, body fat mass, bone mass, and water content. The subject's personal data includes previously measured weight and bioimpedance. The body composition measurement unit 55 may identify the subject by comparing previously measured weight and bioimpedance with the currently measured weight and bioimpedance. The body composition measurement unit 55 acquires the identified subject's personal data from the storage unit 27.
[0034] The standing balance measurement unit 56 measures the balance (standing balance) of the subject when standing on the surface of the biological information measurement device 1, based on the measurement value output from the second sensor unit 24. The standing balance measurement unit 56 may measure the standing balance of the subject by calculating the position of the center of gravity of the subject when standing. The standing balance measurement unit 56 may measure the standing balance of the subject according to a predetermined algorithm.
[0035] The cardiovascular measurement unit 57 measures the cardiovascular condition of the person being measured who is standing on the surface of the biological information measurement device 1 based on the measurement values output from the second sensor unit 24 and the bioimpedance output from the impedance measurement unit 22 in accordance with a predetermined algorithm. The cardiovascular measurement unit 57 measures a BCG (ballistocardiogram), which is the vibration of blood pumped from the heart, based on the measurement values output from the second sensor unit 24. The cardiovascular measurement unit 57 measures a leg IPG (impedance pulse wave) and a foot IPG (impedance pulse wave) based on the bioimpedance output from the impedance measurement unit 22. The leg IPG is an index indicating changes in the amount of blood in the blood vessels of the legs. The foot IPG is an index indicating changes in the amount of blood in the blood vessels of the feet. The cardiovascular measurement unit 57 creates an average waveform of the foot IPG (foot IPG waveform) based on the leg IPG. The cardiovascular measurement unit 57 calculates a PTT (pulse transit time) from the BCG waveform and characteristic points of the foot IPG waveform.
[0036] FIG. 6 illustrates the relationship between the BCG waveform, the foot IPG waveform, and the PTT. As shown in FIG. 6, the PTT (pulse wave transit time) can be calculated by calculating the difference (time) between the reference point of the BCG waveform and the characteristic point of the foot IPG waveform. The cardiovascular measurement unit 57 calculates the PWV (pulse wave velocity) by dividing the measurement section distance by the PTT. Since the PWV value increases with blood vessel stiffness, the PWV is used as an index of blood vessel stiffness. The cardiovascular measurement unit 57 converts the PWV (pulse wave velocity) into an index (cardiovascular index) representing cardiac function and blood vessel status based on a predetermined algorithm, and calculates the cardiovascular index. To measure the cardiovascular status of the subject, the subject must maintain a state of no or minimal body movement for approximately 20 to 30 seconds. Therefore, the cardiovascular measurement unit 57 starts measuring the cardiovascular status of the subject when the subject is in a state of no or minimal body movement.
[0037] The detection unit 41 detects the riding style selected by the subject from among a plurality of riding styles on the surface of the biological information measurement device 1. The measurement unit 42 operates differently depending on the riding style detected by the detection unit 41. By having the measurement unit 42 perform different operations depending on the riding style detected by the detection unit 41, usability in measuring biological information is improved.
[0038] The order detection unit 51 detects the order in which the subject's left foot and right foot are placed on the surface of the biological information measurement device 1, thereby detecting the manner of placement selected by the subject. The operation of the measurement unit 42 differs depending on the order in which the left and right feet of the person being measured are placed on the surface of the biological information measurement device 1. The measurement unit 42 performs different operations depending on the order in which the left and right feet of the person being measured are placed on the surface of the biological information measurement device 1, thereby improving usability in measuring biological information.
[0039] The direction detection unit 52 detects the riding style selected by the subject by detecting the direction in which the subject is facing when he or she steps on the surface of the biological information measurement device 1. Therefore, the operation of the measurement unit 42 differs depending on the direction in which the subject is facing when he or she steps on the surface of the biological information measurement device 1. The measurement unit 42 performs different operations depending on the direction in which the subject is facing when he or she steps on the surface of the biological information measurement device 1, thereby improving usability in measuring biological information.
[0040] The placement detection unit 53 detects the riding style selected by the subject by detecting the placement of the subject's feet on the surface of the biological information measurement device 1. Therefore, the operation of the measurement unit 42 differs depending on the placement of the subject's feet on the surface of the biological information measurement device 1. The measurement unit 42 performs different operations depending on the placement of the subject's feet on the surface of the biological information measurement device 1, thereby improving usability in measuring biological information.
[0041] Next, detection of the riding style selected by the subject will be described. The riding style of the subject on the surface of the biological information measuring device 1 includes the order in which the subject's left foot and right foot are placed on the surface of the biological information measuring device 1. The riding style of the subject on the surface of the biological information measuring device 1 also includes the direction in which the subject rides on the biological information measuring device 1, i.e., the direction in which the subject is facing when they are on the surface of the biological information measuring device 1. The riding style of the subject on the surface of the biological information measuring device 1 also includes the arrangement of the subject's feet on the surface of the biological information measuring device 1.
[0042] Measurement items for the biological information of the person being measured may be selected according to the order in which the person's left foot and right foot are placed on the surface of the biological information measuring device 1. When only measuring body weight, if the person's dominant foot is the right foot, it is expected that the person will unconsciously place their right foot first on the biological information measuring device 1. Therefore, for example, the following rules (1-1) and (1-2) may be set in the biological information measuring device 1. The following rules (1-1) and (1-2) are merely examples, and other rules may also be set in the biological information measuring device 1. (1-1) When the subject places their left foot on the surface of the bio-information measuring device 1 and then their right foot on the surface of the bio-information measuring device 1, the subject's weight, body composition, standing balance and cardiovascular condition are measured. (1-2) When the subject places their right foot on the surface of the biological information measuring device 1 and then their left foot on the surface of the biological information measuring device 1, the subject's weight and body composition are measured.
[0043] The person being measured may also be aware of the following rules (1-3) and (1-4): The following rules (1-3) and (1-4) are examples, and the person being measured may also be aware of other rules. (1-3) When measuring body weight, body composition, standing balance, and cardiovascular condition, the subject places his / her left foot on the surface of the biological information measurement device 1, and then places his / her right foot on the surface of the biological information measurement device 1. (1-4) When measuring body weight and body composition, the subject places his / her right foot on the surface of the biological information measurement device 1, and then places his / her left foot on the surface of the biological information measurement device 1.
[0044] The subject may operate the operation unit 11 to set at least one of the plurality of measurement items in the biological information measurement device 1. Alternatively, the subject may operate an information processing device to set at least one of the plurality of measurement items in the biological information measurement device 1. For example, the measurement items for the case where the subject places the left foot on the surface of the biological information measuring device 1 and then the right foot on the surface of the biological information measuring device 1 may be set to the biological information measuring device 1 as measurement items of body weight, body composition, standing balance, and cardiovascular condition. For example, the measurement items for the case where the subject places the right foot on the surface of the biological information measuring device 1 and then the left foot on the surface of the biological information measuring device 1 may be set to the biological information measuring device 1 as measurement items of body weight and body composition.
[0045] The order detection unit 51 detects the order in which the subject's left foot and right foot step on the surface of the biological information measurement device 1, and outputs the detection result. The measurement unit 42 may measure the subject's biological information by selecting at least one measurement item from a plurality of measurement items related to the subject's biological body based on the detection result of the order detection unit 51. The plurality of measurement items related to the subject's biological body include a measurement item for measuring weight, a measurement item for measuring body composition, a measurement item for measuring standing balance, and a measurement item for measuring cardiovascular status.
[0046] The detection process by the order detection unit 51 will be described. The order detection unit 51 may detect (determine) the order in which the subject's left foot and right foot are placed on the surface of the biological information measurement device 1 based on the measurement values output from the electrode unit 21. A plurality of electrodes may be arranged on each of the left and right sides of the surface of the biological information measurement device 1, and the resistance value between each electrode may be measured. For example, after the resistance value between two electrodes arranged on the left side of the surface of the biological information measurement device 1 is detected, the resistance value between two electrodes arranged on the right side of the surface of the biological information measurement device 1 is detected. In this case, the order detection unit 51 detects that the subject's left foot is placed on the surface of the biological information measurement device 1, and then the right foot is placed on the surface of the biological information measurement device 1. For example, after the resistance value between two electrodes arranged on the right side of the surface of the biological information measurement device 1 is detected, the resistance value between two electrodes arranged on the left side of the surface of the biological information measurement device 1 is detected. In this case, the order detection unit 51 detects that the subject's right foot has been placed on the surface of the biological information measurement device 1, and then the subject's left foot has been placed on the surface of the biological information measurement device 1. The two electrodes arranged on the left side of the surface of the biological information measurement device 1 may be electrodes 12 and 14. The two electrodes arranged on the right side of the surface of the biological information measurement device 1 may be electrodes 13 and 15.
[0047] The order detection unit 51 may detect the order in which the left and right feet of the person being measured are placed on the surface of the biological information measurement device 1, based on the measurement value output from the first sensor unit 23. Photoelectric sensors may be arranged on the left and right sides of the surface of the biological information measurement device 1, and the amounts of light received by the photoelectric sensors may be measured.
[0048] FIG. 7 is a diagram illustrating the arrangement of photoelectric sensors. In the example illustrated in FIG. 7, photoelectric sensor 71 is arranged between electrode 12 and electrode 14, and photoelectric sensor 72 is arranged between electrode 12 and electrode 14. Photoelectric sensors 71 and 72 each include an LED (Light Emitting Diode) that emits light and a photodiode that receives light. The first sensor unit 23 may include the photoelectric sensors 71 and 72. It is preferable to arrange the photoelectric sensor 71 near electrode 12 so that the photoelectric sensor 71 reliably contacts the sole of the subject's left foot when the subject stands on the surface of the biological information measuring device 1. For example, the photoelectric sensor 71 may be arranged near electrode 12 so that the photoelectric sensor 71 contacts the sole of the subject's left big toe. The photoelectric sensor 71 may also be arranged in the region between dotted line A1 and electrode 12 in FIG. 7. The photoelectric sensor 71 may also be arranged near electrode 14. A photoelectric sensor 71 may be disposed in the region between the dotted line A2 and the electrode 14 in FIG.
[0049] The photoelectric sensor 72 may be disposed near the electrode 13. The photoelectric sensor 72 may be disposed in the region between the dotted line A3 in FIG. 7 and the electrode 13. The photoelectric sensor 72 may be disposed near the electrode 15. The photoelectric sensor 72 may be disposed in the region between the dotted line A4 in FIG. 7 and the electrode 15. This may be done.
[0050] When the subject places his / her left foot on the surface of the biological information measuring device 1, the measurement value (light intensity or voltage value) output from the photoelectric sensor 71 changes. For example, after the measurement value output from the photoelectric sensor 71 changes, the measurement value output from the photoelectric sensor 72 changes. The order detection unit 51 detects that the subject places his / her left foot on the surface of the biological information measuring device 1, and then the subject places his / her right foot on the surface of the biological information measuring device 1. In this case, the order detection unit 51 outputs a detection result that the subject places his / her left foot on the surface of the biological information measuring device 1, and then the subject places his / her right foot on the surface of the biological information measuring device 1. The measurement unit 42 may select all of the measurement items from among a plurality of measurement items related to the subject's living body, and measure the subject's biological information.
[0051] For example, the measurement value output from photoelectric sensor 71 changes after the measurement value output from photoelectric sensor 72 changes. In this case, the order detection unit 51 detects that the subject's right foot has placed on the surface of the biological information measurement device 1, and then the subject's left foot has placed on the surface of the biological information measurement device 1.
[0052] The order detection unit 51 may detect the order in which the left and right feet of the subject are placed on the surface of the biological information measurement device 1, based on the measurement values output from the load cells 31 to 34 of the second sensor unit 24. For example, after the measurement value output from the load cell 31 or 33 is detected, the measurement value output from the load cell 32 or 34 is detected. In this case, the order detection unit 51 detects that the subject's left foot is placed on the surface of the biological information measurement device 1, and then the right foot is placed on the surface of the biological information measurement device 1. For example, after the measurement value output from the load cell 32 or 34 is detected, the measurement value output from the load cell 31 or 33 is detected. In this case, the order detection unit 51 detects that the subject's right foot is placed on the surface of the biological information measurement device 1, and then the left foot is placed on the surface of the biological information measurement device 1.
[0053] When the detection result of the order detection unit 51 indicates that the subject's right foot was placed on the surface of the biological information measurement device 1, and then the left foot was placed on the surface, the measurement unit 42 may select a measurement item for measuring weight and a measurement item for measuring body composition from among the multiple measurement items related to the subject's biological information, and measure the subject's biological information. Alternatively, the measurement unit 42 may perform the following process instead of this process. The measurement unit 42 may select a measurement item for measuring weight from among the multiple measurement items related to the subject's biological information, and measure the subject's biological information. Since only the subject's weight is measured, and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened. The measurement unit 42 may select a measurement item for measuring weight and a measurement item for measuring standing balance from among the multiple measurement items related to the subject's biological information, and measure the subject's biological information. Since the subject's weight and standing balance are measured, and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened. The measurement unit 42 may measure the biological information of the subject by selecting a measurement item for measuring weight, a measurement item for measuring body composition, and a measurement item for measuring standing balance from among a plurality of measurement items related to the subject's biological information. Since the subject's weight, body composition, and standing balance are measured and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened.
[0054] Marks for guiding the order in which the subject places their left and right feet on the surface of the biological information measuring device 1 may be provided on the surface of the biological information measuring device 1. Fig. 8 is a schematic diagram of the configuration of the biological information measuring device 1 according to the embodiment. In Fig. 8, lighting units such as LEDs are provided in areas B1 and B2 on the surface of the biological information measuring device 1. Areas B1 and B2 on the surface of the biological information measuring device 1 The lighting units provided in areas B1 and B2 on the surface of the biological information measuring device 1 can be turned on, flashing, or turned off. The lighting units provided in areas B1 and B2 on the surface of the biological information measuring device 1 can be turned on or flashing to encourage the subject to consciously place their left foot on the surface of the biological information measuring device 1. This can improve the subject's awareness of the ability to select a measurement target by placing their left foot first on the surface of the biological information measuring device 1 and help to make it a habit. Instead of providing lighting units such as LEDs, marks of a predetermined shape can be provided in areas B1 and B2 on the surface of the biological information measuring device 1. If the biological information measuring device 1 has a function to link with a smartphone brought with the subject during measurement, the lighting units can be turned on or flashed in a state appropriate for the subject, depending on the measurement items to be prioritized and set in advance on the smartphone by the subject, or on measurement items automatically selected from measurement trends over a predetermined period.
[0055] Fig. 9 is a schematic diagram of a biological information measuring device 1 according to an embodiment. As shown in Fig. 9, the display unit 10 may display at least one measurement item among a plurality of measurement items related to the living body of the subject, and may also display a graphic to guide the subject in the order in which to place their left and right feet on the surface of the biological information measuring device 1. The display unit 10 may also display a message to guide the subject in the order in which to place their left and right feet on the surface of the biological information measuring device 1.
[0056] FIG. 10 is a schematic diagram of a biological information measuring device 1 according to an embodiment. Electrode 12 is an electrode (first electrode) that can come into contact with the sole of one of the feet (left foot) of the person being measured, and is composed of a plurality of electrodes. Electrode 14 is an electrode that can come into contact with the sole of one of the feet (left foot) of the person being measured, and is composed of a plurality of electrodes. Electrode 13 is an electrode that can come into contact with the sole of the other of the feet (right foot) of the person being measured, and is composed of a single electrode. Electrode 15 is an electrode (second electrode) that can come into contact with the sole of the other of the feet (right foot) of the person being measured, and is composed of a single electrode. As shown in FIG. 10, the number of electrodes (first electrodes) that can come into contact with the sole of one of the feet (left foot) of the person being measured and the number of electrodes (second electrodes) that can come into contact with the sole of the other of the feet (right foot) of the person being measured may be different. 10, by making the number of first electrodes greater than the number of second electrodes, the subject may be guided to consciously place his / her left foot on the surface of the biological information measuring device 1. In this way, when measuring weight, body composition, standing balance, and cardiovascular status, the subject may consider it preferable to place his / her left foot first on the surface of the biological information measuring device 1. This makes it easier for the subject to distinguish the difference depending on the order in which the feet are placed on the surface of the biological information measuring device 1, which leads to an improved awareness of the possibility of selecting the measurement target and to the development of a habit of doing so.
[0057] 10, the shape of the electrode (first electrode) that can come into contact with the sole of one of the subject's feet (left foot) may be different from the shape of the electrode (second electrode) that can come into contact with the sole of the other of the subject's feet (right foot). For example, by giving the first electrode a distinctive shape, the subject may be guided to consciously place his or her left foot on the surface of the biological information measuring device 1.
[0058] Measurement items for the biological information of the subject may be selected depending on the direction the subject is facing when standing on the surface of the biological information measuring device 1. For example, the following rules (2-1) and (2-2) are set in the biological information measuring device 1. The following rules (2-1) and (2-2) are merely examples, and other rules may also be set in the biological information measuring device 1. (2-1) When the subject faces a first direction and stands on the surface of the biological information measuring device 1, the subject's weight is measured. The first direction is the direction in which the display unit 10 is arranged. (2-2) When the subject stands on the surface of the biological information measuring device 1 while facing the second direction, the subject's weight, body composition, standing balance, and cardiovascular condition are measured. The second direction is a direction different from the direction in which the display unit 10 is arranged.
[0059] Since the measurement of standing balance and cardiovascular status is easily affected by the subject's body movements, such as when the subject moves his or her head to view the display of the measurement progress, it is preferable that the display unit 10 is hidden from the subject. Therefore, it is preferable that the above-mentioned rule (2-2) be set in the biological information measurement device 1.
[0060] The person being measured may also be aware of the following rules (2-3), (2-4), and (2-5). The following rules (2-3), (2-4), and (2-5) are examples, and the person being measured may also be aware of other rules. (2-3) When measuring weight, the person to be measured stands on the surface of the biological information measuring device 1 while facing in the first direction. (2-4) When measuring the weight, body composition, standing balance, and cardiovascular condition, the person to be measured stands on the surface of the biological information measuring device 1 while facing in the second direction. (2-5) When the subject stands on the surface of the biological information measuring device 1, the subject first touches the heel of the foot to the surface of the biological information measuring device 1, and then touches the toe of the foot to the surface of the biological information measuring device 1.
[0061] The person being measured may operate the operation unit 11 to set at least one of the multiple measurement items in the biological information measuring device 1. The person being measured may also operate the information processing device to set at least one of the multiple measurement items in the biological information measuring device 1. For example, the measurement item of body weight may be set in the biological information measuring device 1 as the measurement item when the person being measured stands on the surface of the biological information measuring device 1 while facing in a first direction. For example, the measurement items of body weight, body composition, standing balance, and cardiovascular condition may be set in the biological information measuring device 1 as the measurement items when the person being measured stands on the surface of the biological information measuring device 1 while facing in a second direction.
[0062] The direction detection unit 52 detects the direction in which the subject is facing when the subject stands on the surface of the biological information measurement device 1, and outputs the detection result. The measurement unit 42 may select at least one measurement item from a plurality of measurement items related to the subject's biological information based on the detection result of the direction detection unit 52, and measure the subject's biological information.
[0063] The detection process by the direction detection unit 52 will be described. The direction detection unit 52 may detect (determine) the direction in which the subject is facing when the subject stands on the surface of the biological information measurement device 1, based on the measurement value output from the electrode unit 21. By arranging multiple electrodes on the surface of the biological information measurement device 1 and measuring the resistance value between the electrodes, the direction detection unit 52 may detect the direction in which the subject is facing when the subject stands on the surface of the biological information measurement device 1. The electrode unit 21 may have multiple electrodes. Electrodes 12 to 15 may be used.
[0064] 11 to 15 are schematic configuration diagrams of a biological information measuring device 1 according to an embodiment. The detection process performed by the direction detection unit 52 will be described with reference to FIGS. 11 to 15. The operation unit 11 and electrodes 12 to 15 are not shown in FIGS. 11 to 15. In FIGS. 11 to 15, it is assumed that the electrode 12 is arranged in an area C1 on the surface of the biological information measuring device 1, the electrode 13 is arranged in an area C2 on the surface of the biological information measuring device 1, the electrode 14 is arranged in an area C3 on the surface of the biological information measuring device 1, and the electrode 15 is arranged in an area C4 on the surface of the biological information measuring device 1. Also, in FIGS. 11 to 13, lighting units such as LEDs are provided in areas D1 to D4 on the surface of the biological information measuring device 1. The lighting units provided in areas D1 to D4 on the surface of the biological information measuring device 1 can be turned on, blink, or turned off.
[0065] The lighting sections provided in the areas D3 and D4 on the surface of the biological information measuring device 1 light up or blink. By doing so, the subject may be guided to consciously place the heel of his / her left foot on area C3 on the surface of the biological information measuring device 1, and the heel of his / her right foot on area C4 on the surface of the biological information measuring device 1. By having the subject place the heel of his / her left foot on area C3 on the surface of the biological information measuring device 1 and the heel of his / her right foot on area C4 on the surface of the biological information measuring device 1, the subject's awareness of the possibility of selecting a measurement target is improved and the subject becomes accustomed to the selection.
[0066] The direction detection unit 52 may detect the order in which the subject's left foot comes into contact with the areas C1 and C3 on the surface of the biological information measurement device 1, based on the measurement values output from the electrode unit 21. Fig. 12 schematically shows a state in which the subject's left foot is placed on the surface of the biological information measurement device 1. For example, after the resistance value between two electrodes placed in the area C3 on the surface of the biological information measurement device 1 is detected, the resistance value between two electrodes placed in the area C1 on the surface of the biological information measurement device 1 is detected. In this case, the direction detection unit 52 outputs a detection result indicating that the direction in which the subject is facing when they place themselves on the surface of the biological information measurement device 1 is the first direction.
[0067] Furthermore, the direction detection unit 52 may detect the order in which the subject's right foot comes into contact with areas C2 and C4 on the surface of the biological information measurement device 1, based on the measurement values output from the electrode unit 21. For example, after detecting the resistance value between two electrodes arranged in area C4 on the surface of the biological information measurement device 1, the direction detection unit 52 detects the resistance value between two electrodes arranged in area C2 on the surface of the biological information measurement device 1. In this case, the direction detection unit 52 outputs a detection result indicating that the direction in which the subject is facing when standing on the surface of the biological information measurement device 1 is the first direction.
[0068] The lighting units provided in areas D1 and D2 on the surface of the biological information measuring device 1 may be lit or flashed to guide the subject to consciously place the heel of their left foot on area C2 on the surface of the biological information measuring device 1, and to consciously place the heel of their right foot on area C1 on the surface of the biological information measuring device 1. This leads to improved awareness and habituation of the possibility of selecting a measurement target by placing the heel of their left foot first on area C2 on the surface of the biological information measuring device 1 and the heel of their right foot first on area C1 on the surface of the biological information measuring device 1.
[0069] The direction detection unit 52 may detect the order in which the subject's left foot comes into contact with areas C2 and C4 on the surface of the biological information measurement device 1, based on the measurement values output from the electrode unit 21. Fig. 13 schematically shows a state in which the subject's left foot is placed on the surface of the biological information measurement device 1. For example, after the resistance value between two electrodes arranged in area C2 on the surface of the biological information measurement device 1 is detected, the resistance value between two electrodes arranged in area C4 on the surface of the biological information measurement device 1 is detected. In this case, the direction detection unit 52 outputs a detection result indicating that the direction in which the subject is facing when they place themselves on the surface of the biological information measurement device 1 is the second direction.
[0070] Furthermore, the direction detection unit 52 may detect the order in which the subject's right foot comes into contact with areas C1 and C3 on the surface of the biological information measurement device 1, based on the measurement values output from the electrode unit 21. For example, after detecting the resistance value between two electrodes arranged in area C1 on the surface of the biological information measurement device 1, the direction detection unit 52 detects the resistance value between two electrodes arranged in area C3 on the surface of the biological information measurement device 1. In this case, the direction detection unit 52 outputs a detection result indicating that the direction in which the subject is facing when standing on the surface of the biological information measurement device 1 is the second direction.
[0071] If the direction in which the subject faces when standing on the surface of biological information measuring device 1 is the second direction, the electrode functions are switched to measure the subject's biological information. For example, in the example shown in Fig. 13, electrodes 14 and 15 may function as current application electrodes for applying a constant current to the subject's body, and electrodes 12 and 13 may function as voltage measurement electrodes for measuring the voltage when the current is applied.
[0072] The direction detection unit 52 detects whether the left foot of the person being measured is in a normal position based on the measurement value output from the electrode unit 21. The order in which the areas C1 and C2 on the surface of the biological information measuring device 1 are contacted may also be detected. Fig. 14 schematically shows a state in which the left foot of the subject is placed on the surface of the biological information measuring device 1. For example, after the resistance value between two electrodes arranged in area C1 on the surface of the biological information measuring device 1 is detected, the resistance value between two electrodes arranged in area C2 on the surface of the biological information measuring device 1 is detected. In this case, the direction detecting unit 52 outputs a detection result indicating that the direction in which the subject is facing when he or she is placed on the surface of the biological information measuring device 1 is the second direction.
[0073] Furthermore, the direction detection unit 52 may detect the order in which the subject's right foot comes into contact with areas C3 and C4 on the surface of the biological information measurement device 1, based on the measurement values output from the electrode unit 21. For example, after the resistance value between two electrodes arranged in area C3 on the surface of the biological information measurement device 1 is detected, the resistance value between two electrodes arranged in area C4 on the surface of the biological information measurement device 1 is detected. In this case, the direction detection unit 52 outputs a detection result indicating that the direction in which the subject is facing when standing on the surface of the biological information measurement device 1 is the second direction.
[0074] If the direction in which the subject faces when standing on the surface of biological information measuring device 1 is the second direction, the electrode functions are switched to measure the subject's biological information. For example, in the example shown in Fig. 14, electrodes 13 and 15 may function as current application electrodes for applying a constant current to the subject's body, and electrodes 12 and 14 may function as voltage measurement electrodes for measuring the voltage when the current is applied.
[0075] The direction detection unit 52 may detect the order in which the subject's left foot comes into contact with areas C3 and C4 on the surface of the biological information measurement device 1, based on the measurement values output from the electrode unit 21. Fig. 15 schematically shows a state in which the subject's left foot is placed on the surface of the biological information measurement device 1. For example, after the resistance value between two electrodes arranged in area C4 on the surface of the biological information measurement device 1 is detected, the resistance value between two electrodes arranged in area C3 on the surface of the biological information measurement device 1 is detected. In this case, the direction detection unit 52 outputs a detection result indicating that the direction in which the subject is facing when they place themselves on the surface of the biological information measurement device 1 is the second direction.
[0076] Furthermore, the direction detection unit 52 may detect the order in which the subject's right foot comes into contact with areas C1 and C2 on the surface of the biological information measurement device 1, based on the measurement values output from the electrode unit 21. For example, after the resistance value between two electrodes arranged in area C2 on the surface of the biological information measurement device 1 is detected, the resistance value between two electrodes arranged in area C1 on the surface of the biological information measurement device 1 is detected. In this case, the direction detection unit 52 outputs a detection result indicating that the direction in which the subject is facing when standing on the surface of the biological information measurement device 1 is the second direction.
[0077] If the direction in which the subject is facing when standing on the surface of biological information measuring device 1 is the second direction, the electrode functions are switched to measure the subject's biological information. For example, in the example shown in Fig. 15, electrodes 12 and 14 may function as current application electrodes for applying a constant current to the subject's body, and electrodes 14 and 15 may function as voltage measurement electrodes for measuring the voltage when the current is applied.
[0078] The heel side of the subject's foot is rougher than the toe side of the subject's foot, and the resistance value of the heel side of the subject's foot is greater than the resistance value of the toe side of the subject's foot. The direction detection unit 52 may detect the direction in which the subject is facing when standing on the surface of the biological information measurement device 1 by comparing the resistance value of the heel side of the subject's foot with the resistance value of the toe side of the subject's foot. If the resistance value between the two electrodes arranged in area C3 on the surface of the biological information measurement device 1 is greater than the resistance value between the two electrodes arranged in area C1 on the surface of the biological information measurement device 1, the direction detection unit 52 outputs a detection result that the direction in which the subject is facing when standing on the surface of the biological information measurement device 1 is the first direction. If the resistance value between the two electrodes arranged in area C2 on the surface of the biological information measurement device 1 is greater than the resistance value between the two electrodes arranged in area C1 on the surface of the biological information measurement device 1, the direction detection unit 52 outputs a detection result that the direction in which the subject is facing when standing on the surface of the biological information measurement device 1 is the first direction. If the resistance value is greater than the resistance value between the two electrodes arranged at 4, the direction detection unit 52 outputs a detection result that the direction in which the person being measured is facing when standing on the surface of the biological information measurement device 1 is the second direction.
[0079] When the detection result of the direction detection unit 52 indicates that the subject's right foot was placed on the surface of the biological information measurement device 1, the measurement unit 42 may select a measurement item for measuring weight and a measurement item for measuring body composition from among the multiple measurement items related to the subject's biological information, and measure the subject's biological information. Alternatively, the measurement unit 42 may perform the following process instead of this process. The measurement unit 42 may select a measurement item for measuring weight from among the multiple measurement items related to the subject's biological information, and measure the subject's biological information. Since only the subject's weight is measured and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened. The measurement unit 42 may select a measurement item for measuring weight and a measurement item for measuring standing balance from among the multiple measurement items related to the subject's biological information, and measure the subject's biological information. Since the subject's weight and standing balance are measured and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened. The measurement unit 42 may measure the biological information of the subject by selecting a measurement item for measuring weight, a measurement item for measuring body composition, and a measurement item for measuring standing balance from among a plurality of measurement items related to the subject's biological information. Since the subject's weight, body composition, and standing balance are measured and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened.
[0080] The direction detection unit 52 may detect the order in which the subject's left foot comes into contact with areas C1 and C3 on the surface of the biological information measuring device 1, based on the measurement values output from the first sensor unit 23. Photoelectric sensors may be arranged in each of areas C1 and C3 on the surface of the biological information measuring device 1, and the amounts of light received by the photoelectric sensors may be measured.

The biological information measuring device 1 has an appearance that is substantially symmetrical in the vertical and horizontal directions. That is, the length and width of the biological information measuring device 1 are the same, and the appearance does not give the impression of directional orientation. The operation unit is integrated with the display unit 10 and is, for example, a touch panel. The display unit 10 is provided in the center of the surface of the biological information measuring device 1. The display unit 10 is disposed in the center of each diagonal of the electrodes 12 to 15. With the biological information measuring device 1 shown in FIG. 16, the soles of the feet of the subject are surely in contact with the electrodes 12 to 15 regardless of the direction in which the subject steps on the surface of the biological information measuring device 1. The display unit 10 changes the display orientation of the measurement results, data, and information depending on the direction in which the subject is facing when stepping on the surface of the biological information measuring device 1.
[0089] As shown in FIG. 16, a lighting unit 16 is provided on the surface of the biological information measuring device 1. The lighting unit 16 can be turned on, flashing, or turned off. When the lighting unit 16 lights up or flashes, the person being measured stands on the surface of the biological information measuring device 1 while facing a first direction or a second direction with the lighting unit 16 as the reference. The first direction is the direction in which the lighting unit 16 is arranged. The second direction is a direction different from the direction in which the lighting unit 16 is arranged.

[0093] Measurement items for the biological information of the subject may be selected according to the position of the subject's feet on the surface of the biological information measuring device 1. For example, the following rules (3-1) and (3-2) may be set in the biological information measuring device 1. The following rules (3-1) and (3-2) are merely examples, and other rules may also be set in the biological information measuring device 1. (3-1) When the subject's feet are positioned in the first position, the subject's weight, body composition, standing balance, and cardiovascular status are measured. The first position is the position of the subject's feet when the subject stands on the surface of the biological information measuring device 1 with a wide gap between the toes of the left foot and the toes of the right foot. (3-2) When the subject's feet are positioned in the second position, the subject's weight and body composition are measured. The second position is the position of the subject's feet when the subject stands on the surface of the biological information measuring device 1 with their left and right feet parallel to each other.
[0094] The person being measured may also be aware of the following rules (3-3) and (3-4): The following rules (3-3) and (3-4) are merely examples, and the person being measured may also be aware of other rules.

(3-4) When measuring body weight and body composition, the subject places his or her left and right feet on the surface of the biological information measuring device 1 with the feet parallel to each other.
[0095] The subject may operate the operation unit 11 to set at least one of the plurality of measurement items in the biological information measuring device 1. The subject may also operate the information processing device to set at least one of the plurality of measurement items in the biological information measuring device 1. For example, the measurement items of body weight, body composition, standing balance, and cardiovascular condition may be set in the biological information measuring device 1 when the subject places the left and right feet on the surface of the biological information measuring device 1 with a wide gap between the toes of the left and right feet. For example, the measurement items of body weight and body composition may be set in the biological information measuring device 1 when the subject places the left and right feet parallel to each other and on the surface of the biological information measuring device 1.
[0096] The placement detection section 53 may detect (determine) the placement of the subject's feet on the surface of the biological information measurement device 1 based on the measurement values output from the electrode section 21. The placement detection section 53 detects (determines) the electrodes among the plurality of electrodes arranged on the surface of the biological information measurement device 1 that are contacted by the subject's feet. By identifying two electrodes that are in communication, the placement of the subject's feet on the surface of the biological information measurement device 1 may be detected (determined).
[0097] 18 schematically shows a state in which the subject's left and right feet are placed on the surface of the biological information measuring device 1. The subject's left foot is in contact with electrodes 12A and 14, so that electrode 12A and electrode 14 are in a conductive state. The subject's right foot is in contact with electrodes 13A and 15, so that electrode 13A and electrode 15 are in a conductive state. The placement detection unit 53 determines that the placement of the subject's feet on the surface of the biological information measuring device 1 is the first placement. In this case, the placement detection unit 53 outputs a detection result that the placement of the subject's feet on the surface of the biological information measuring device 1 is the first placement.
[0098] 19 schematically shows a state in which the subject's left and right feet are placed on the surface of the biological information measuring device 1. The subject's left foot is in contact with electrodes 12B and 14, so that electrode 12B and electrode 14 are in a conductive state. The subject's right foot is in contact with electrodes 13B and 15, so that electrode 13B and electrode 15 are in a conductive state. The placement detection unit 53 determines that the placement of the subject's feet on the surface of the biological information measuring device 1 is the second placement. In this case, the placement detection unit 53 outputs a detection result that the placement of the subject's feet on the surface of the biological information measuring device 1 is the second placement.
[0099] The placement detection unit 53 detects the placement of the subject's feet on the surface of the biological information measurement device 1 and outputs the detection result. The measurement unit 42 may select at least one measurement item from a plurality of measurement items related to the subject's biological information based on the detection result of the placement detection unit 53, and measure the subject's biological information.
[0100] A description will be given of a case where the above arrangements (3-1) and (3-2) are set in the biological information measuring device 1. When the detection result of the arrangement detection unit 53 indicates that the measurement subject's feet are arranged in the first arrangement, the measurement unit 42 may select all of the measurement items among the plurality of measurement items related to the measurement subject's biological information and measure the measurement subject's biological information.
[0101] If the detection result of the position detection unit 53 indicates that the position of the subject's feet is the second position, the measurement unit 42 may select a measurement item for measuring weight and a measurement item for measuring body composition from among the multiple measurement items related to the subject's body, and measure the subject's biological information. Alternatively, the measurement unit 42 may perform the following process instead of this process. The measurement unit 42 may select a measurement item for measuring weight from among the multiple measurement items related to the subject's body, and measure the subject's biological information. Since only the subject's weight is measured and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened. The measurement unit 42 may select a measurement item for measuring weight and a measurement item for measuring standing balance from among the multiple measurement items related to the subject's body, and measure the subject's biological information. Since the subject's weight and standing balance are measured and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened. The measurement unit 42 may measure the biological information of the subject by selecting a measurement item for measuring weight, a measurement item for measuring body composition, and a measurement item for measuring standing balance from among a plurality of measurement items related to the subject's biological information. Since the subject's weight, body composition, and standing balance are measured and no other measurement items are measured, the time from start to completion of measurement of the subject's biological information is shortened.
[0102] Instead of the above-mentioned agreements (3-1) and (3-2), the following agreements (4-1) and (4-2) may be set in the biological information measuring device 1. The following agreements (4-1) and (4-2) are merely examples, and other agreements may be set in the biological information measuring device 1. (4-1) When the subject's feet are positioned in the first position, the subject's weight is measured. (4-2) When the subject's foot position is the second position, the subject's weight, body composition, standing balance, and cardiovascular condition are measured.
[0103] Instead of the above (3-3) and (3-4), the subject may be aware of the following (4-3) and (4-4). The following (4-3) and (4-4) are examples, and the subject may be aware of other rules. (4-3) When measuring body weight, the subject places his or her left and right feet on the surface of the biological information measuring device 1 with a wide gap between the toes of the left and right feet. (4-4) When measuring body weight, body composition, standing balance, and cardiovascular condition, the subject places his or her left and right feet on the surface of the biological information measuring device 1 with the feet parallel to each other.
[0104] In the biological information measuring device 1 shown in FIGS. 17 to 19, if the subject changes the measurement method after standing on the surface of the biological information measuring device 1, the subject does not need to move their feet significantly or re-step on the surface of the biological information measuring device 1. The subject can change the position of their feet by moving their toes only as little as necessary. By providing a curved recessed portion in electrode 14, the left foot can be easily rotated around the heel of the left foot. By providing a curved recessed portion in electrode 15, the right foot can be easily rotated around the heel of the right foot.
[0105] FIG. 20 is a schematic diagram of a biological information measuring device 1 according to an embodiment. An operation unit 11 and electrodes 12 to 15 are not shown in FIG. 20.

The lighting unit provided in the area E1 on the surface of the biological information measuring device 1 can be turned on, blinking, or turned off. When the lighting unit provided in the area E1 on the surface of the biological information measuring device 1 turns on or blinks, a W-shaped display pattern (a shape representing weight) is displayed on the surface of the biological information measuring device 1. For example, when measuring the weight of a person being measured with a wide gap between the toes of the person's left foot and the toes of the person's right foot, a W-shaped display pattern is displayed on the surface of the biological information measuring device 1. This makes it possible to guide the person being measured to consciously place their left and right feet on the W-shaped display pattern displayed on the surface of the biological information measuring device 1.
[0106] FIG. 21 is a schematic diagram of a biological information measuring device 1 according to an embodiment. The biological information measuring device 1 shown in FIG. 21 includes a display unit 10, an operation unit 11, and electrodes 12C, 12D, 12E, 12F, 13C, 13D, 13E, 13F, 14A, 14B, 14C, 14D, 15A, 15B, 15C, and 15D. When the subject places their left foot on the surface of the biological information measuring device 1, electrodes 12C and 12F and electrodes 14A to 14D are used to determine the state of continuity. When the subject places their right foot on the surface of the biological information measuring device 1, electrodes 13C, 13F and electrodes 15A to 15D are used to determine the state of continuity. By arranging multiple elongated electrodes in comparison with the electrode arrangement of the biological information measuring device 1 shown in FIG. 17, it is possible to prevent the device from becoming large, as in the biological information measuring device 1 shown in FIG. 21.
[0107] The time taken by the measurement unit 42 to measure the biometric information of the subject may vary depending on the riding style detected by the detection unit 41. The measurement time of the biometric information will be explained. The measurement time of the biometric information for the measurement items of body weight and body composition (body weight and body composition) is longer than the measurement time of the biometric information for the measurement item of body weight (body weight). The measurement time of the biometric information for the measurement items of body weight and standing balance (body weight and standing balance) is longer than the measurement time of the biometric information (body weight). The measurement time of the biometric information for the measurement items of body weight, body composition, standing balance and cardiovascular condition (body weight, body composition, standing balance and cardiovascular condition) is longer than the measurement time of the biometric information (body weight and body composition). The measurement time of the biometric information (body weight, body composition, standing balance and cardiovascular condition) is longer than the measurement time of the biometric information (body weight and standing balance). At least one of the multiple measurement items is selected depending on the riding style detected by the detection unit 41, and the subject is When the biological information of the subject is measured, the time during which the measurement section 42 measures the biological information of the subject varies depending on the measurement item.
[0108] The measurement unit 42 may set the time for measuring the subject's biological information according to the riding style detected by the detection unit 41. When a measurement item for cardiovascular condition is selected and the subject's biological information is measured, a first predetermined time may be set as the time for measuring the biological information, or a second predetermined time longer than the first predetermined time may be set as the time for measuring the biological information. By setting the second predetermined time as the time for measuring the biological information, the measurement unit 42 can collect more detailed data than when the first predetermined time is set as the time for measuring the biological information.
[0109] The measurement unit 42 may set the time for measuring the biological information of the subject based on the detection result of the order detection unit 51. For example, if the subject places his / her left foot on the surface of the biological information measurement device 1 and then his / her right foot on the surface of the biological information measurement device 1, the measurement unit 42 may set a first predetermined time as the measurement time for the biological information and select a measurement item for the cardiovascular condition to measure the biological information of the subject. For example, if the subject places his / her right foot on the surface of the biological information measurement device 1 and then his / her left foot on the surface of the biological information measurement device 1, the measurement unit 42 may set a second predetermined time as the measurement time for the biological information and select a measurement item for the cardiovascular condition to measure the biological information of the subject. The measurement unit 42 may set the time for measuring the biological information of the subject based on the detection result of the direction detection unit 52. The measurement unit 42 may set the time for measuring the biological information of the subject based on the detection result of the placement detection unit 53.
[0110] The measurement results of the biological information measured by the measurement unit 42 are stored in the storage unit 27. The measurement results of the biological information may be sent to the subject's information processing device via the communication unit 26. The measurement results of the biological information may be stored in the storage unit of the subject's information processing device. The recording target of the measurement results of the biological information may differ depending on the riding style detected by the detection unit 41. The measurement unit 42 may decide whether or not to record the measurement results of the biological information based on the detection result of the detection unit 41.
[0111] The measurement unit 42 may determine whether to record the measurement result based on the detection result of the order detection unit 51. For example, if the person being measured places their left foot on the surface of the biological information measurement device 1 and then their right foot on the surface of the biological information measurement device 1, the measurement unit 42 selects the measurement item of body weight, measures the biological information of the person being measured, and records the measurement result of the biological information in the database of the storage unit 27. For example, if the person being measured places their right foot on the surface of the biological information measurement device 1 and then their left foot on the surface of the biological information measurement device 1, the measurement unit 42 selects the measurement item of body weight, measures the biological information of the person being measured, and does not record the measurement result of the biological information in the database of the storage unit 27. The measurement unit 42 may determine whether to record the measurement result based on the detection result of the direction detection unit 52. The measurement unit 42 may determine whether to record the measurement result based on the detection result of the placement detection unit 53.
[0112] The measurement unit 42 may determine whether to record the measurement results of at least one of the multiple measurement items based on the detection result of the order detection unit 51. For example, if the person being measured places their left foot on the surface of the biological information measurement device 1 and then their right foot on the surface of the biological information measurement device 1, the measurement unit 42 selects the measurement items of body weight, body composition, standing balance, and cardiovascular condition. The measurement unit 42 measures the biological information of the person being measured and records the measurement results of at least one of the measurement items of body weight, body composition, standing balance, and cardiovascular condition in the database of the storage unit 27. For example, if the person being measured places their right foot on the surface of the biological information measurement device 1 and then their left foot on the surface of the biological information measurement device 1, the measurement unit 42 selects the measurement items of body weight, body composition, standing balance, and cardiovascular condition. The measurement unit 42 measures the biological information of the person being measured and records the measurement results of at least one of the measurement items of body weight, body composition, standing balance, and cardiovascular condition in the database of the storage unit 27. The measurement results are not recorded in the database of the storage unit 27. The measurement unit 42 may determine whether to record the measurement results based on the detection results of the direction detection unit 52. The measurement unit 42 may determine whether to record the measurement results based on the detection results of the placement detection unit 53.
[0113] When the measurement of the subject's biological information is being performed for all of the multiple measurement items related to the subject's biological activity, the display unit 10 may not display any information while the measurement unit 42 is performing the measurement process. The subject's behavior of looking at the information displayed on the display unit 10 (looking at their feet) affects the measurement of their cardiovascular condition. By having the display unit 10 not display any information while the measurement unit 42 is performing the measurement process, the subject's body movement can be suppressed, improving the accuracy of measuring their cardiovascular condition.
