[0009] The problem that the invention aims to solve

[0010] In a typical body composition analyzer, there are force sensors and electrodes that come into contact with the body. These are used to measure weight and bioimpedance, thereby displaying results related to body weight and various body compositions. The measurement time is several seconds, and the impact on the results is minimal, even with minor body movements such as the subject moving their head to check the measurement status displayed at their feet. However, when the body composition analyzer is equipped with additional functions such as BCG (cardiocardiogram) measurement via force sensors and IPG (impedance pulse wave) measurement via electrodes, providing cardiovascular status information to the user, body movements such as head and arm movements during measurement significantly affect the results. This prolongs the measurement time or results in errors requiring re-measurement. Furthermore, body composition analyzers are generally configured to collect a series of data simultaneously, displaying the results of all measurements sequentially after a predetermined measurement time. Therefore, the more measurements are performed, the longer the measurement time, including the result display time, becomes. However, in cases such as home-use body composition analyzers, the management object is sometimes only weight values, and the measurement object is limited to weight.

[0011] In Patent Document 1, in the first action, the subject steps onto the weighing scale, places their left foot on the left foot electrode mounted on the footrest, and places their right foot on the same footrest to measure weight. In the second action, the subject spreads their legs and moves their right foot from the footrest to the right foot electrode mounted on the support platform to measure impedance (see paragraphs 0013 and 0014 of Patent Document 1). Therefore, in Patent Document 1, the foot needs to be moved significantly during the measurement, making it impossible to complete the measurement if the foot position remains unchanged at the time of stepping onto the weighing scale, thus reducing usability. In Patent Document 2, the standard method is to place two electrode sections on the left and right sides of the weight measuring unit. The subject steps onto the central weight measuring unit to obtain weight data, and the subject steps onto the two electrode sections to obtain impedance data (see paragraph 0025 of Patent Document 2). Therefore, in Patent Document 2, the foot needs to be moved significantly during the measurement, making it impossible to complete the measurement if the foot position remains unchanged at the time of stepping onto the weight measuring unit or electrode section, thus reducing usability. For example, as in Patent Document 4, if a dedicated weight key is set in the body composition analyzer, an additional dedicated weight key is required, and the key operation before measurement is cumbersome, reducing usability.

[0012] The present invention was made in view of the above-mentioned actual situation, and its purpose is to improve the usability of biological information measurement.

[0013] Solution for solving the problem

[0014] According to one aspect of the present invention, a biometric information measuring device is provided, having a mounting surface for a subject to board. The biometric information measuring device includes: a sensing unit that senses the boarding method selected by the subject from among multiple boarding methods for the mounting surface; and a measuring unit that measures biometric information of the subject, the operation of which varies depending on the boarding method sensed by the sensing unit. The sensing unit senses the boarding method selected by the subject from among multiple boarding methods for the mounting surface of the biometric information measuring device. The measuring unit operates differently depending on the boarding method sensed by the sensing unit. By performing different actions based on the boarding method sensed by the sensing unit, the usability of biometric information measurement is improved.

[0015] The sensing unit senses the boarding method selected by the subject by sensing the order in which the subject's left and right feet step onto the mounting surface. The action of the sensing unit varies depending on the order in which the subject's left and right feet step onto the mounting surface of the biometric information measuring device. This difference in the sequence of steps improves the usability of biometric information measurement.

[0016] The sensing unit senses the direction the subject faces when boarding the mounting surface, and thus senses the boarding method selected by the subject. The action of the sensing unit varies depending on the direction the subject faces when boarding the mounting surface of the biometric information measuring device. This difference in action improves the usability of biometric information measurement.

[0017] The sensing unit senses the seating arrangement of the subject on the mounting surface, and thus senses the chosen mode of transportation. The actions of the sensing unit vary depending on the arrangement of the subject's feet on the mounting surface of the biometric information measuring device. This difference in the actions improves the usability of biometric information measurement.

[0018] The time at which the measuring unit measures the biological information varies depending on the boarding method sensed by the sensing unit. The measurement items for the biological information measured by the measuring unit also vary depending on the boarding method sensed by the sensing unit. Furthermore, the objects on which the measurement results of the biological information are recorded also vary depending on the boarding method sensed by the sensing unit.

[0019] The aforementioned biometric information measuring device includes: a first electrode capable of contacting the sole of one foot of the subject; and a second electrode capable of contacting the sole of the other foot of the subject. The number of the first electrode and the number of the second electrode are different. This allows the subject to be guided to consciously place one or both feet onto the mounting surface of the biometric information measuring device.

[0020] The aforementioned biometric information measuring device includes: a first electrode capable of contacting the sole of one foot of the subject; and a second electrode capable of contacting the sole of the other foot of the subject. The shape of the first electrode is different from the shape of the second electrode. This allows the subject to be guided to consciously place one or both feet onto the mounting surface of the biometric information measuring device.

[0021] It should be noted that the present invention can also be considered as a biological information measurement method in which a computer performs at least a portion of the above-described processing, a biological information measurement method including at least a portion of the above-described processing, a program for causing a computer to perform at least a portion of the above-described processing, or a computer-readable recording medium that non-transitoryly records such a program. As long as the above-described configurations and processes do not create technical contradictions, they can be combined with each other to constitute the present invention.

[0045] The embodiments will now be described with reference to the accompanying drawings. The embodiments shown below are one approach of this application and do not limit the scope of the claims of this application.

[0046] Figure 1This is a schematic diagram of the biometric information measuring device 1 according to the embodiment. The biometric information measuring device 1 includes a display unit 10, an operation unit 11, and electrodes 12 to 15. The biometric information measuring device 1 has a surface (mounting surface) for users or other subjects to ride on. When a subject rides on the surface of the biometric information measuring device 1, the tip side (toe side) of the sole of the left foot contacts electrode 12, and the rear side (heel side) of the sole of the left foot contacts electrode 14. When a subject rides on the surface of the biometric information measuring device 1, the tip side (toe side) of the sole of the right foot contacts electrode 13, and the rear side (heel side) of the sole of the right foot contacts electrode 15.

[0047] A display section 10 is provided on the surface of the bio-information measuring device 1. An operation section 11 is provided in the center of the surface of the bio-information measuring device 1. For example, the subject steps onto the surface of the bio-information measuring device 1 in such a manner that the top and rear sides of the sole of the subject's left foot contact the electrodes 12 and 14 respectively, and the top and rear sides of the sole of the subject's right foot contact the electrodes 13 and 15 respectively.

[0048] The operation unit 11 includes switches 110 to 113. Switch 110 receives input indicating whether to turn the power supply of the bio-information measuring device 1 on or off, as well as input indicating the start and end of the measurement. Switch 111 receives input indicating that various data stored in the bio-information measuring device 1 will be displayed on the display unit 10. Switches 112 and 113 receive input, etc., for selecting various data displayed on the display unit 10. Furthermore, switches 111 to 113 are used to receive data input.

[0049] Figure 2 This is a block diagram illustrating the configuration of the biological information measuring device 1 according to the embodiment. The biological information measuring device 1 includes a display unit 10, an operation unit 11, a control unit 20, an electrode unit 21, an impedance measuring unit 22, a first sensor unit 23, a second sensor unit 24, a temperature measuring unit 25, a communication unit 26, and a storage unit 27. The display unit 10 employs, for example, a liquid crystal display panel such as an LCD (Liquid Crystal Display) or an EL (Electroluminescence) display. The display unit 10 displays measurement results, various information, and data. The operation unit 11 receives operations from the person being measured.

[0050] The control unit 20 is a control device (controller) that controls the overall operation of the biological information measuring device 1. The control unit 20 can be composed of dedicated equipment or a general-purpose computer. The control unit 20 possesses hardware resources such as a CPU (Central Processing Unit), memory, and storage. The memory can be RAM (Random Access Memory). The storage device can be a non-volatile storage device such as ROM (Read Only Memory) or flash memory. The functions of each processing unit (functional unit) in the control unit 20 are implemented by expanding the program stored in the storage into memory and executing it with the processor. It should be noted that the configuration of the control unit 20 is not limited to this. For example, all or part of the functions of the control unit 20 can be constituted by circuits such as ASIC (Application Specific Integrated Circuit) or FPGA (Field-Programmable Gate Array), or all or part of the functions of the control unit 20 can be executed by a cloud server or other devices.

[0051] Electrode section 21 includes electrodes 12 to 15. Electrodes 12 to 15 are used to apply a constant current to the body of the subject for measuring the bioimpedance of the subject, and to measure the voltage when the current is applied. Electrode section 21 may also include other electrodes different from electrodes 12 to 15. Impedance measuring section 22 measures the bioimpedance of the subject based on the values ​​of the current applied to the body of the subject and the voltage measured when the current is applied. Impedance measuring section 22 outputs the bioimpedance of the subject to control section 20. Impedance measuring section 22 may also output the bioimpedance of the subject as an impedance pulse wave.

[0052] The first sensor unit 23 has a photoelectric sensor. The first sensor unit 23 outputs the measured value obtained by the photoelectric sensor to the control unit 20. The second sensor unit 24 has multiple force sensors (strain gauges). The second sensor unit 24 outputs the measured value obtained by the multiple force sensors to the control unit 20.

[0053] Figure 3 This is a diagram showing the configuration of multiple force sensors. (For example...) Figure 3As shown, force sensors 31 to 34 are disposed on the back side of the bio-information measuring device 1. Force sensors 31 to 34 are respectively disposed near the four corners of the back side of the bio-information measuring device 1. Considering the influence of the subject's body movements, it is preferable to arrange the force sensors 31 to 34 such that they apply loads equally to each of them. Alternatively, in the thickness direction of the bio-information measuring device 1, electrode 12 overlaps with force sensor 31, electrode 13 overlaps with force sensor 32, electrode 14 overlaps with force sensor 33, and electrode 15 overlaps with force sensor 34. The second sensor unit 24 may also include an accelerometer. The second sensor unit 24 may also output the measured value obtained by the accelerometer to the control unit 20.

[0054] Figure 4 This is a diagram showing the configuration of multiple force sensors and acceleration sensors. (For example...) Figure 4 As shown, force sensors 31-34 and an acceleration sensor 35 are disposed on the back side of the bio-information measuring device 1. Force sensors 31-34 are respectively disposed near the four corners of the back side of the bio-information measuring device 1. Considering the influence of the subject's body movements, it is preferable to arrange the force sensors 31-34 such that they apply loads equally to each of them. Alternatively, in the thickness direction of the bio-information measuring device 1, electrode 12 overlaps with force sensor 31, electrode 13 overlaps with force sensor 32, electrode 14 overlaps with force sensor 33, and electrode 15 overlaps with force sensor 34. The acceleration sensor 35 is disposed in the center of the back side of the bio-information measuring device 1.

[0055] The temperature measuring unit 25 measures the temperature of the soles of the feet of the subject who is riding on the surface of the bio-information measuring device 1. The temperature measuring unit 25 has a temperature sensor. The temperature sensor is disposed on the surface of the bio-information measuring device 1. The temperature sensor may also be disposed near the electrodes 12 to 15.

[0056] The communication unit 26 is an interface for communication via wired or wireless means. The communication unit 26 communicates with the information processing device of the subject being measured. The information processing device may be, for example, a portable terminal, a smartphone, a tablet computer, or a personal computer.

[0057] Storage unit 27 stores information and data. Storage unit 27 may also include at least one of RAM or other memory. The memory may also be a non-volatile storage device such as ROM or flash memory. Storage unit 27 stores various information such as the personal data of the subject and the measurement results of the biometric information measuring device 1. Personal data is used when calculating the body composition of the subject. Personal data includes at least the subject's height and weight, and may also include the subject's age, gender, and other information. The subject's weight is measured by the subject riding on the surface of the biometric information measuring device 1. The subject's height, age, gender, and other information are input into the biometric information measuring device 1 by operating the operation unit 11.

[0058] Figure 5 This is a block diagram illustrating the functional configuration of the control unit 20. The control unit 20 includes a sensing unit 41 and a measuring unit 42. The sensing unit 41 includes a sequence sensing unit 51, a direction sensing unit 52, and a placement sensing unit 53. The measuring unit 42 includes a weight measuring unit 54, a body composition measuring unit 55, a standing balance measuring unit 56, and a cardiovascular measuring unit 57.

[0059] The sensing unit 41 senses the boarding method selected by the subject among multiple boarding methods on the surface of the biometric information measuring device 1. The measuring unit 42 measures the biometric information of the subject. The sequence sensing unit 51 senses the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1 based on the measurement values ​​output from at least one of the electrode unit 21, the first sensor unit 23, and the second sensor unit 24, thereby sensing the boarding method selected by the subject.

[0060] The direction sensing unit 52 senses the direction the subject is facing when boarding the surface of the biometric 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 sensing the boarding method selected by the subject. The configuration sensing unit 53 senses the configuration of the subject's feet on the surface of the biometric 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 sensing the boarding method selected by the subject.

[0061] The weight measurement unit 54 measures the weight of the subject riding on the surface of the bio-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 riding on the surface of the bio-information measurement device 1 according to a predetermined algorithm, based on the subject's personal data, the bio-impedance output from the impedance measurement unit 22, and the subject's weight. Body composition is an indicator representing 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 (Body Mass Index), muscle percentage, muscle mass, body fat mass, bone mass, and water content. The subject's personal data includes previously measured weight and bio-impedance. The body composition measurement unit 55 can also determine the subject by comparing previously measured weight and bio-impedance with the currently measured weight and bio-impedance. The body composition measurement unit 55 retrieves the determined subject's personal data from the storage unit 27.

[0062] The standing balance measuring unit 56 measures the balance of the subject standing on the surface of the biometric information measuring device 1 based on the measurement values ​​output from the second sensor unit 24. The standing balance measuring unit 56 can also measure the subject's standing balance by calculating the position of the subject's center of gravity while standing. The standing balance measuring unit 56 can also measure the subject's standing balance according to a predetermined algorithm.

[0063] The cardiovascular measurement unit 57 measures the cardiovascular state of the subject aboard the surface of the bio-information measurement device 1 according to a prescribed algorithm, based on the measurement values ​​output from the second sensor unit 24 and the bio-impedance output from the impedance measurement unit 22. The cardiovascular measurement unit 57 measures the BCG (cardiac impact map), 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 the leg IPG (impedance pulse wave) and foot IPG (impedance pulse wave) based on the bio-impedance output from the impedance measurement unit 22. The leg IPG is an indicator of changes in the blood volume within the blood vessels of the leg. The foot IPG is an indicator of changes in the blood volume within the blood vessels of the foot. The cardiovascular measurement unit 57 generates an average waveform of the foot IPG (foot IPG waveform) based on the leg IPG. The cardiovascular measurement unit 57 calculates the PTT (pulse wave propagation time) based on the characteristic points of the BCG waveform and the foot IPG waveform.

[0064] Figure 6 This is a diagram illustrating the relationship between the BCG waveform, the IPG waveform, and the PTT (Pulse Tolerance). For example... Figure 6As shown, the PTT (pulse wave propagation time) can be calculated by obtaining 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 interval distance by the PTT. The stiffer the blood vessels, the larger the PWV value; therefore, PWV is used as an indicator of blood vessel stiffness. Based on a prescribed algorithm, the cardiovascular measurement unit 57 converts the PWV (pulse wave propagation velocity) into an indicator (cardiovascular index) representing cardiac function and vascular status, and calculates the cardiovascular index. In measuring the cardiovascular status of the subject, it is necessary to maintain a state of no body movement or minimal body movement for approximately 20 to 30 seconds. Therefore, the cardiovascular measurement unit 57 begins measuring the cardiovascular status of the subject while the subject is in a state of no body movement or minimal body movement.

[0065] The sensing unit 41 senses the boarding method selected by the subject from among multiple boarding methods on the surface of the biometric information measuring device 1. The measuring unit 42 operates differently depending on the boarding method sensed by the sensing unit 41. By performing different actions based on the boarding method sensed by the sensing unit 41, the usability of biometric information measurement is improved.

[0066] The sequence sensing unit 51 senses the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1, thereby sensing the mounting method selected by the subject. Therefore, the measuring unit 42 operates differently depending on the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1. By performing different actions based on the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1, the usability of biometric information measurement is improved.

[0067] The direction sensing unit 52 senses the direction the subject faces when boarding the surface of the bio-information measuring device 1, thereby sensing the boarding method selected by the subject. Therefore, the measuring unit 42 operates differently depending on the direction the subject faces when boarding the surface of the bio-information measuring device 1. By performing different actions based on the direction the subject faces when boarding the surface of the bio-information measuring device 1, the usability of bio-information measurement is improved.

[0068] The sensing unit 53 senses the arrangement of the subject's feet on the surface of the biometric information measuring device 1, thereby sensing the subject's chosen mode of transportation. Therefore, the measuring unit 42 operates differently depending on the arrangement of the subject's feet on the surface of the biometric information measuring device 1. Because the measuring unit 42 performs different actions depending on the arrangement of the subject's feet on the surface of the biometric information measuring device 1, the usability of biometric information measurement is improved.

[0069] Next, the sensing of the mounting method selected by the subject will be explained. The mounting method of the subject on the surface of the biometric information measuring device 1 includes the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1. The mounting method of the subject on the surface of the biometric information measuring device 1 includes the direction in which the subject steps onto the biometric information measuring device 1, that is, the direction the subject is facing when stepping onto the surface of the biometric information measuring device 1. The mounting method of the subject on the surface of the biometric information measuring device 1 includes the arrangement of the subject's feet on the surface of the biometric information measuring device 1.

[0070] Alternatively, the measurement items related to the subject's biometric information can be selected based on the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1. In the case of measuring only weight, if the dominant foot is the right foot, it is anticipated that the subject will unconsciously step onto the biometric information measuring device 1 starting with the right foot. Therefore, rules (1-1) and (1-2) below can be set in the biometric information measuring device 1, for example. Rules (1-1) and (1-2) below are examples; other rules can also be set in the biometric information measuring device 1.

[0071] (1-1) After the subject's left foot steps onto the surface of the bio-information measuring device 1, and then the subject's right foot steps onto the surface of the bio-information measuring device 1, the subject's weight, body composition, standing balance, and cardiovascular status are measured.

[0072] (1-2) When the subject's right foot is on the surface of the bio-information measuring device 1 and the subject's left foot is on the surface of the bio-information measuring device 1, the subject's weight and body composition are measured.

[0073] In addition, the test subject may also have prior knowledge of rules (1-3) and (1-4) below. Rules (1-3) and (1-4) below are examples; the test subject may also have prior knowledge of other rules.

[0074] (1-3) When measuring weight, body composition, standing balance and cardiovascular status, the subject puts his left foot on the surface of the bio-information measuring device 1 and then his right foot on the surface of the bio-information measuring device 1.

[0075] (1-4) When measuring weight and body composition, the subject puts his right foot on the surface of the bio-information measuring device 1 and then puts his left foot on the surface of the bio-information measuring device 1.

[0076] The person being tested can operate the operation unit 11 to set at least one of the multiple measurement items to the biometric information measuring device 1. Furthermore, the person being tested can operate the information processing device to set at least one of the multiple measurement items to the biometric information measuring device 1. For example, as a measurement item where the person being tested places their left foot on the surface of the biometric information measuring device 1 and then their right foot on the surface of the biometric information measuring device 1, measurement items for weight, body composition, standing balance, and cardiovascular status can be set to the biometric information measuring device 1. For example, as a measurement item where the person is placed their right foot on the surface of the biometric information measuring device 1 and then their left foot on the surface of the biometric information measuring device 1, measurement items for weight and body composition can be set to the biometric information measuring device 1.

[0077] The sequence sensing unit 51 senses the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1 and outputs the sensing results. The measuring unit 42 can also, based on the sensing results of the sequence sensing unit 51, select at least one of several measurement items related to the subject's biometrics to measure the subject's biometric information. These multiple measurement items related to the subject's biometrics include weight measurement, body composition measurement, standing balance measurement, and cardiovascular status measurement.

[0078] The sensing process implemented by the sequential sensing unit 51 will be described. The sequential sensing unit 51 can also sense (determine) the order in which the subject's left and right feet land on the surface of the biometric information measuring device 1 based on the measured values ​​output from the electrode unit 21. Multiple electrodes can also be arranged on the left and right sides of the surface of the biometric information measuring device 1, respectively, and the resistance value between each electrode can be measured. For example, after sensing (measuring) the resistance value between two electrodes arranged on the left side of the surface of the biometric information measuring device 1, the resistance value between two electrodes arranged on the right side of the surface of the biometric information measuring device 1 is sensed. In this case, the sequential sensing unit 51 senses that the subject's left foot landed on the surface of the biometric information measuring device 1, and then the subject's right foot landed on the surface of the biometric information measuring device 1. For example, after sensing the resistance value between two electrodes arranged on the right side of the surface of the biometric information measuring device 1, the resistance value between two electrodes arranged on the left side of the surface of the biometric information measuring device 1 is sensed. In this case, the sequential sensing unit 51 senses that the subject's right foot landed on the surface of the biometric information measuring device 1, and then the subject's left foot landed on the surface of the biometric information measuring device 1. The two electrodes disposed on the left side of the surface of the biological information measuring device 1 can be electrode 12 and electrode 14. The two electrodes disposed on the right side of the surface of the biological information measuring device 1 can be electrode 13 and electrode 15.

[0079] The sequence sensing unit 51 can also sense the order in which the subject's left and right feet step onto the surface of the biometric information measuring device 1, based on the measurement values ​​output from the first sensor unit 23. Alternatively, photoelectric sensors can be disposed on the left and right sides of the surface of the biometric information measuring device 1, respectively, to measure the amount of light received by the photoelectric sensors.

[0080] Figure 7 This is a diagram showing the configuration of the photoelectric sensor. Figure 7 In the example shown, photoelectric sensor 71 is disposed between electrode 12 and electrode 14, and photoelectric sensor 72 is disposed between electrode 13 and electrode 15. Photoelectric sensors 71 and 72 have an LED (Light Emitting Diode) as a light-emitting part and a photodiode as a light-receiving part. The first sensor unit 23 may also include photoelectric sensors 71 and 72. Preferably, photoelectric sensor 71 is disposed near electrode 12 such that when the subject is mounted on the surface of the biometric information measuring device 1, photoelectric sensor 71 reliably contacts the sole of the subject's left foot. For example, photoelectric sensor 71 may also be disposed near electrode 12 such that it contacts the bottom of the subject's left big toe. Figure 7A photoelectric sensor 71 is disposed in the area between the dashed line A1 and electrode 12. The photoelectric sensor 71 can also be disposed near electrode 14. Figure 7 A photoelectric sensor 71 is disposed in the area between the dashed line A2 and the electrode 14.

[0081] The photoelectric sensor 72 can also be positioned near the electrode 13. Alternatively, it can be... Figure 7 A photoelectric sensor 72 is disposed in the area between the dashed line A3 and electrode 13. The photoelectric sensor 72 can also be disposed near electrode 15. Figure 7 A photoelectric sensor 72 is disposed in the area between the dashed line A4 and the electrode 15.

[0082] When the subject's left foot steps onto the surface of the bio-information measuring device 1, the measured value (light intensity or voltage value) output from the photoelectric sensor 71 changes. For example, after the measured value output from the photoelectric sensor 71 changes, the measured value output from the photoelectric sensor 72 also changes. The sequential sensing unit 51 senses that after the subject's left foot steps onto the surface of the bio-information measuring device 1, the subject's right foot steps onto the surface of the bio-information measuring device 1. In this case, the sequential sensing unit 51 outputs the sensing result that after the subject's left foot steps onto the surface of the bio-information measuring device 1, the subject's right foot steps onto the surface of the bio-information measuring device 1. The measuring unit 42 can also select all of the multiple measuring items related to the subject's bio-information to measure the subject's bio-information.

[0083] For example, after the measured value output from photoelectric sensor 72 changes, the measured value output from photoelectric sensor 71 also changes. In this case, after the sequential sensing unit 51 senses that the subject's right foot has stepped onto the surface of the bio-information measuring device 1, the subject's left foot steps onto the surface of the bio-information measuring device 1.

[0084] The sequence sensing unit 51 can also sense the order in which the subject's left and right feet land on the surface of the biometric information measuring device 1 based on the measured values ​​output from the force sensors 31-34 of the second sensor unit 24. For example, after sensing the measured values ​​output from force sensors 31 or 33, it senses the measured values ​​output from force sensors 32 or 34. In this case, the sequence sensing unit 51 senses that the subject's left foot lands on the surface of the biometric information measuring device 1, and then the subject's right foot lands on the surface of the biometric information measuring device 1. For example, after sensing the measured values ​​output from force sensors 32 or 34, it senses the measured values ​​output from force sensors 31 or 33. In this case, the sequence sensing unit 51 senses that the subject's right foot lands on the surface of the biometric information measuring device 1, and then the subject's left foot lands on the surface of the biometric information measuring device 1.

[0085] If the sensing result of the sequential sensing unit 51 indicates that the subject's right foot lands on the surface of the biometric information measuring device 1 followed by the left foot, the measuring unit 42 can also select the measurement item of measuring weight and the measurement item of measuring body composition from among the multiple measurement items related to the subject's biometrics to measure the subject's biometrics. Alternatively, the measuring unit 42 can perform the following processing instead of this process: The measuring unit 42 can also select the measurement item of measuring weight from among the multiple measurement items related to the subject's biometrics to measure the subject's biometrics. Since only the subject's weight is measured, and other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biometrics is shortened. The measuring unit 42 can also select the measurement item of measuring weight and the measurement item of measuring standing balance from among the multiple measurement items related to the subject's biometrics to measure the subject's biometrics. Since only the subject's weight and standing balance are measured, and other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biometrics is shortened. The measurement unit 42 can also select from multiple measurement items related to the subject's organism to measure weight, body composition, and standing balance to measure the subject's biological information. Since the subject's weight, body composition, and standing balance are measured, while other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biological information is shortened.

[0086] Markings can also be provided on the surface of the bio-information measuring device 1 to guide the left and right feet of the subject onto the surface of the bio-information measuring device 1 in a specific order. Figure 8 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. Figure 8 In this biometrics device 1, areas B1 and B2 on the surface are equipped with illuminated parts such as LEDs. Each illuminated part in areas B1 and B2 can be turned on, flashed, and turned off. The illumination or flashing of these illuminated parts can guide the subject's left foot to consciously step onto the surface of the biometrics device 1. This improves the ability to select the target for measurement by starting with the left foot, and helps establish a habit. Alternatively, markings of a predetermined shape can be provided in areas B1 and B2 on the surface of the biometrics device 1. When the biometrics device 1 has the function of linking with a smartphone during measurement, the illuminated parts can be automatically selected based on the measurement items that the subject has pre-set as priority targets on the smartphone, or the measurement items selected automatically from the measurement tendencies of a specified period, to suit the subject's state.

[0087] Figure 9 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. Figure 9 As shown, the display unit 10 can also display at least one of a plurality of measurement items related to the subject's organism, and display a graphic showing the order in which the subject's left and right feet are guided onto the surface of the organism information measuring device 1. Furthermore, the display unit 10 can also display a message showing the order in which the subject's left and right feet are guided onto the surface of the organism information measuring device 1.

[0088] Figure 10 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. Electrode 12 is an electrode (first electrode) that can contact the sole of one of the subjects' feet (left foot), and is composed of multiple electrodes. Electrode 14 is an electrode that can contact the sole of one of the subjects' feet (left foot), and is composed of multiple electrodes. Electrode 13 is an electrode that can contact the sole of the other foot (right foot), and is composed of one electrode. Electrode 15 is an electrode (second electrode) that can contact the sole of the other foot (right foot), and is composed of one electrode. Figure 10 As shown, the number of electrodes (first electrodes) that can contact the sole of one foot (left foot) of the subject can differ from the number of electrodes (second electrodes) that can contact the sole of the other foot (right foot). For example, as... Figure 10 As shown, by having more first electrodes than second electrodes, the subject's left foot can be consciously guided onto the surface of the biometric information measuring device 1. Therefore, when measuring weight, body composition, standing balance, and cardiovascular status, it is considered preferable for the subject to step onto the surface of the biometric information measuring device 1 starting with their left foot. This makes it easier to discern differences caused by the order in which the subject places their feet onto the surface of the biometric information measuring device 1, improving the ability to select suitable subjects and fostering a habit.

[0089] Not limited to Figure 10 In the example shown, the shape of the electrode (first electrode) that can contact the sole of one of the subject's feet (left foot) can be different from the shape of the electrode (second electrode) that can contact the sole of the other foot (right foot). For example, by making the first electrode a characteristic shape, the subject's left foot can be guided to consciously touch the surface of the bio-information measuring device 1.

[0090] The measurement items related to the subject's biological information can also be selected based on the direction the subject faces when boarding the surface of the biological information measurement device 1. For example, the rules (2-1) and (2-2) below can be set in the biological information measurement device 1. The rules (2-1) and (2-2) below are examples, and other rules can also be set in the biological information measurement device 1.

[0091] (2-1) The weight of the subject is measured when the subject boards the surface of the biological information measuring device 1 facing a first direction. The first direction is the direction in which the display unit 10 is located.

[0092] (2-2) When the subject boards the surface of the biometric information measuring device 1 facing the second direction, the subject's weight, body composition, standing balance, and cardiovascular status are measured. The second direction is a different direction from the direction in which the display unit 10 is located.

[0093] The measurement of standing balance and cardiovascular status is easily affected by the subject's body movements, such as head movements caused by the subject wanting to see the display of the measurement process. Therefore, it is preferable that the subject cannot see the display unit 10. Therefore, it is preferable to set the rule (2-2) above in the biological information measurement device 1.

[0094] In addition, the test subject may also have prior knowledge of the rules (2-3), (2-4), and (2-5) below. The rules (2-3), (2-4), and (2-5) below are examples, and the test subject may also have prior knowledge of other rules.

[0095] (2-3) When measuring body weight, the subject boards the surface of the biological information measuring device 1 facing the first direction.

[0096] (2-4) While measuring weight, body composition, standing balance and cardiovascular status, the subject boarded the surface of the bio-information measuring device 1 facing the second direction.

[0097] (2-5) When the subject steps onto the surface of the bio-information measuring device 1, the heel side of the foot contacts the surface of the bio-information measuring device 1, and then the toe side of the foot contacts the surface of the bio-information measuring device 1.

[0098] The person being tested can operate the operation unit 11 to set at least one of the multiple measurement items to the biometric information measuring device 1. Furthermore, the person being tested can operate the information processing device to set at least one of the multiple measurement items to the biometric information measuring device 1. For example, as a measurement item when the person being tested boards the surface of the biometric information measuring device 1 facing a first direction, the measurement of weight can be set to the biometric information measuring device 1. For example, as a measurement item when the person being tested boards the surface of the biometric information measuring device 1 facing a second direction, the measurement of weight, body composition, standing balance, and cardiovascular status can be set to the biometric information measuring device 1.

[0099] The direction sensing unit 52 senses the direction the subject is facing when boarding the surface of the biometric information measuring device 1, and outputs the sensing results. The measuring unit 42 may also select at least one of multiple measuring items related to the subject's biometrics based on the sensing results of the direction sensing unit 52, and measure the subject's biometric information.

[0100] The sensing process implemented by the direction sensing unit 52 will be described. The direction sensing unit 52 can also sense (determine) the direction the subject is facing when boarding the surface of the biometric information measuring device 1, based on the measurement values ​​output from the electrode unit 21. By arranging multiple electrodes on the surface of the biometric information measuring device 1 and measuring the resistance values ​​between each electrode, the direction sensing unit 52 can also sense the direction the subject is facing when boarding the surface of the biometric information measuring device 1. The electrode unit 21 may also have multiple electrodes. Electrodes 12 to 15 may also be used.

[0101] Figures 11-15 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. (Refer to...) Figures 11-15 The sensing processing implemented by the orientation sensing unit 52 will be explained. Figures 11-15 The diagram of the operating part 11 and electrodes 12-15 is omitted. Figures 11-15 In this device, an electrode 12 is disposed in region C1 of the surface of the biological information measuring device 1, an electrode 13 is disposed in region C2 of the surface of the biological information measuring device 1, an electrode 14 is disposed in region C3 of the surface of the biological information measuring device 1, and an electrode 15 is disposed in region C4 of the surface of the biological information measuring device 1. Furthermore, in Figures 11-13 In the biological information measuring device 1, LEDs and other illuminated parts are provided in areas D1 to D4 on the surface of the device. Each illuminated part in areas D1 to D4 on the surface of the biological information measuring device 1 can be lit, flashed, and turned off.

[0102] Alternatively, by illuminating or flashing the illuminated areas D3 and D4 on the surface of the bio-information measuring device 1, the subject can be guided to consciously place their left heel on area C3 of the bio-information measuring device 1 and their right heel on area C4. This improves the ability to select the subject for measurement and helps cultivate a habit by having the subject begin placing their heel on area C3 of the bio-information measuring device 1 from their left heel and on area C4 from their right heel.

[0103] The orientation sensing unit 52 can also sense the sequence of contact between the subject's left foot and regions C1 and C3 on the surface of the bio-information measuring device 1, based on the measurement values ​​output from the electrode unit 21. Figure 12 The diagram schematically illustrates the state of the subject's left foot stepping onto the surface of the biometric information measuring device 1. For example, after sensing the resistance value between the two electrodes in region C3 of the surface of the biometric information measuring device 1, the resistance value between the two electrodes in region C1 of the surface of the biometric information measuring device 1 is sensed. In this case, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject is facing when stepping onto the surface of the biometric information measuring device 1 is a first direction.

[0104] Furthermore, the direction sensing unit 52 can also sense the sequence in which the subject's right foot contacts regions C2 and C4 of the surface of the biometric information measuring device 1, based on the measurement values ​​output from the electrode unit 21. For example, after sensing the resistance value between the two electrodes disposed on the surface of region C4 of the biometric information measuring device 1, the resistance value between the two electrodes disposed on the surface of region C2 of the biometric information measuring device 1 is sensed. In this case, the direction sensing unit 52 outputs a sensing result stating that the direction the subject is facing when boarding the surface of the biometric information measuring device 1 is a first direction.

[0105] Alternatively, by illuminating or flashing the illuminated areas D1 and D2 on the surface of the bio-information measuring device 1, the subject can be guided to consciously place their left heel on area C2 of the surface and their right heel on area C1. This improves the ability to select the subject and helps cultivate a habit by having the subject begin placing their heel on area C2 from their left heel and on area C1 from their right heel.

[0106] The orientation sensing unit 52 can also sense the sequence of contact between the subject's left foot and regions C2 and C4 on the surface of the bio-information measuring device 1, based on the measurement values ​​output from the electrode unit 21. Figure 13 The diagram schematically illustrates the state of the subject's left foot stepping onto the surface of the biometric information measuring device 1. For example, after sensing the resistance value between the two electrodes disposed in region C2 on the surface of the biometric information measuring device 1, the resistance value between the two electrodes disposed in region C4 on the surface of the biometric information measuring device 1 is sensed. In this case, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject was facing when stepping onto the surface of the biometric information measuring device 1 was the second direction.

[0107] Furthermore, the direction sensing unit 52 can also sense the sequence in which the subject's right foot contacts regions C1 and C3 of the surface of the biometric information measuring device 1, based on the measurement values ​​output from the electrode unit 21. For example, after sensing the resistance value between the two electrodes disposed on region C1 of the surface of the biometric information measuring device 1, the resistance value between the two electrodes disposed on region C3 of the surface of the biometric information measuring device 1 is sensed. In this case, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject was facing when boarding the surface of the biometric information measuring device 1 was the second direction.

[0108] When the subject is facing the second direction while alighting from the biometric information measuring device 1, the electrode function is switched to measure the subject's biometric information. For example, in Figure 13 In the example shown, electrodes 14 and 15 can function as current application electrodes for applying a constant current to the body of the subject, and electrodes 12 and 13 can function as voltage measurement electrodes for measuring the voltage when the applied current is applied.

[0109] The orientation sensing unit 52 can also sense the sequence of contact between the subject's left foot and areas C1 and C2 on the surface of the bio-information measuring device 1, based on the measurement values ​​output from the electrode unit 21. Figure 14 The diagram schematically illustrates the state of the subject's left foot stepping onto the surface of the biometric information measuring device 1. For example, after sensing the resistance value between the two electrodes in region C1 of the surface of the biometric information measuring device 1, the resistance value between the two electrodes in region C2 of the surface of the biometric information measuring device 1 is sensed. In this case, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject was facing when stepping onto the surface of the biometric information measuring device 1 was the second direction.

[0110] Furthermore, the direction sensing unit 52 can also sense the sequence in which the subject's right foot contacts regions C3 and C4 of the surface of the biometric information measuring device 1, based on the measurement values ​​output from the electrode unit 21. For example, after sensing the resistance value between the two electrodes disposed in region C3 of the surface of the biometric information measuring device 1, the resistance value between the two electrodes disposed in region C4 of the surface of the biometric information measuring device 1 is then sensed. In this case, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject was facing when boarding the surface of the biometric information measuring device 1 was the second direction.

[0111] When the subject is facing the second direction while alighting from the biometric information measuring device 1, the electrode function is switched to measure the subject's biometric information. For example, in Figure 14 In the example shown, electrodes 13 and 15 can function as current application electrodes for applying a constant current to the body of the subject, and electrodes 12 and 14 can function as voltage measurement electrodes for measuring the voltage when the applied current is applied.

[0112] The orientation sensing unit 52 can also sense the sequence of contact between the subject's left foot and regions C3 and C4 on the surface of the bio-information measuring device 1, based on the measurement values ​​output from the electrode unit 21. Figure 15 The diagram schematically illustrates the state of the subject's left foot stepping onto the surface of the biometric information measuring device 1. For example, after sensing the resistance value between the two electrodes in region C4 of the surface of the biometric information measuring device 1, the resistance value between the two electrodes in region C3 of the surface of the biometric information measuring device 1 is sensed. In this case, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject was facing when stepping onto the surface of the biometric information measuring device 1 was the second direction.

[0113] Furthermore, the direction sensing unit 52 can also sense the sequence in which the subject's right foot contacts regions C1 and C2 of the surface of the biometric information measuring device 1, based on the measurement values ​​output from the electrode unit 21. For example, after sensing the resistance value between the two electrodes disposed on the surface of region C2 of the biometric information measuring device 1, the resistance value between the two electrodes disposed on the surface of region C1 of the biometric information measuring device 1 is sensed. In this case, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject was facing when boarding the surface of the biometric information measuring device 1 was the second direction.

[0114] When the subject is facing the second direction while alighting from the biometric information measuring device 1, the electrode function is switched to measure the subject's biometric information. For example, in Figure 15In the example shown, electrodes 12 and 13 can function as current application electrodes for applying a constant current to the body of the subject, and electrodes 14 and 15 can function as voltage measurement electrodes for measuring the voltage when the applied current is applied.

[0115] The heel side of the subject's foot is drier and rougher than the toe side, and the resistance value of the heel side is greater than that of the toe side. The direction sensing unit 52 can also sense the direction the subject is facing when stepping onto the surface of the biometric information measuring device 1 by comparing the resistance values ​​of the heel side and the toe side. If the resistance value between the two electrodes in region C3 of the surface of the biometric information measuring device 1 is greater than the resistance value between the two electrodes in region C1, the direction sensing unit 52 outputs a sensing result indicating that the direction the subject is facing when stepping onto the surface of the biometric information measuring device 1 is a first direction. When the resistance value between the two electrodes in region C2 on the surface of the bio-information measuring device 1 is greater than the resistance value between the two electrodes in region C4 on the surface of the bio-information measuring device 1, the direction sensing unit 52 outputs a sensing result that the direction the subject is facing when boarding the surface of the bio-information measuring device 1 is the second direction.

[0116] If the direction sensing unit 52 detects that the subject's right foot lands on the surface of the biometric information measuring device 1 followed by their left foot, the measuring unit 42 can select weight measurement and body composition measurement from among the multiple measurement items related to the subject's biometrics to measure the subject's biometrics. Alternatively, the measuring unit 42 can perform the following processing instead: The measuring unit 42 can select weight measurement from among the multiple measurement items related to the subject's biometrics to measure the subject's biometrics. Since only the subject's weight is measured, and other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biometrics is shortened. The measuring unit 42 can also select weight measurement and standing balance measurement from among the multiple measurement items related to the subject's biometrics to measure the subject's biometrics. Since only the subject's weight and standing balance are measured, and other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biometrics is shortened. The measurement unit 42 can also select from multiple measurement items related to the subject's organism to measure weight, body composition, and standing balance to measure the subject's biological information. Since the subject's weight, body composition, and standing balance are measured, while other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biological information is shortened.

[0117] The direction sensing unit 52 can also sense the sequence in which the subject's left foot contacts areas C1 and C3 of the surface of the bio-information measuring device 1, based on the measurement values ​​output from the first sensor unit 23. Alternatively, photoelectric sensors can be disposed on areas C1 and C3 of the surface of the bio-information measuring device 1, respectively, and the amount of light received by the photoelectric sensors can be measured. Similarly, the direction sensing unit 52 can also sense the sequence in which the subject's left foot contacts areas C2 and C4 of the surface of the bio-information measuring device 1, based on the measurement values ​​output from the first sensor unit 23. Alternatively, photoelectric sensors can be disposed on areas C2 and C4 of the surface of the bio-information measuring device 1, respectively, and the amount of light received by the photoelectric sensors can be measured.

[0121] The orientation sensing unit 52 can also sense the sequence in which the subject's left foot contacts areas C1 and C3 on the surface of the biometric information measuring device 1, based on the measured values ​​output from the force sensors 31 and 33 of the second sensor unit 24. Similarly, the orientation sensing unit 52 can sense the sequence in which the subject's right foot contacts areas C2 and C4 on the surface of the biometric information measuring device 1, based on the measured values ​​output from the force sensors 32 and 34 of the second sensor unit 24.

[0125] Figure 16 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. Figure 16 The shown biometric information measuring device 1 includes a display unit 10 and L-shaped electrodes 12-15. The biometric information measuring device 1 has a roughly symmetrical appearance, meaning its dimensions are identical both horizontally and vertically, giving it a non-directional appearance. The operation unit is integrated with the display unit 10, for example, as a touch panel. The display unit 10 is located at the center of the surface of the biometric information measuring device 1. The display unit 10 is positioned at the center of each diagonal line of the electrodes 12-15. Figure 16 The biometric information measuring device 1 shown ensures that the soles of the subject's feet reliably contact the electrodes 12-15 regardless of the direction from which the subject steps onto the surface of the biometric information measuring device 1. The display unit 10 adjusts the orientation of the display of the measurement results, data, and information according to the direction the subject is facing when stepping onto the surface of the biometric information measuring device 1, and displays the measurement results, information, and data accordingly.

[0126] like Figure 16As shown, a light-up section 16 is provided on the surface of the bio-information measuring device 1. The light-up section 16 can be turned on, flashed, and turned off. By turning the light-up section 16 on or flashing, the person being measured boards the surface of the bio-information measuring device 1 in a first direction or a second direction, using the light-up section 16 as a reference. The first direction is the direction in which the light-up section 16 is located. The second direction is a direction different from the direction in which the light-up section 16 is located.

[0127] The biometric measurement device 1 can be mounted on the floor of a building such as a residence. The case of mounting the biometric measurement device 1 on a floor will be described. In the type of biometric measurement device 1 mounted on a floor, the first direction can also be the direction in which a mirror is arranged. When measuring weight, the person being measured steps onto the surface of the biometric measurement device 1 facing the first direction. Thus, the person being measured can measure their weight while looking in the mirror or while looking at their own body shape reflected in the mirror.

[0128] Furthermore, in the type of biometric measurement device 1 assembled on the floor, the second direction can also be the direction the subject faces when their back is to the building wall. When measuring weight, body composition, standing balance, and cardiovascular status, the subject boards the surface of the biometric measurement device 1 facing the second direction. Thus, with the subject's back to the building wall, their weight, body composition, standing balance, and cardiovascular status can be measured. The subject can use the building wall for postural stability.

[0129] Figures 17-19 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. (Refer to...) Figures 17-19 The sensing processing implemented by the configuration sensing unit 53 will be explained. Figures 17-19 The biological information measuring device 1 shown includes a display unit 10, an operation unit 11, and electrodes 12A, 12B, 13A, 13B, 14, and 15.

[0130] The measurement items related to the biological information of the subject can also be selected based on the arrangement of the subject's feet on the surface of the biological information measuring device 1. For example, the rules (3-1) and (3-2) below can also be set in the biological information measuring device 1. The rules (3-1) and (3-2) below are examples, and other rules can also be set in the biological information measuring device 1.

[0131] (3-1) With the subject's feet configured in the first configuration, the subject's weight, body composition, standing balance, and cardiovascular status are measured. The first configuration is the configuration of the subject's feet when the subject is sitting on the surface of the bio-information measuring device 1 with the toe side of the left foot and the toe side of the right foot widened.

[0132] (3-2) When the subject's feet are configured in the second configuration, the subject's weight and body composition are measured. The second configuration is the configuration of the subject's feet when the subject's left and right feet are parallel and the subject is sitting on the surface of the bio-information measuring device 1.

[0133] In addition, the test subject may also learn the rules (3-3) and (3-4) below in advance. The rules (3-3) and (3-4) below are examples, and the test subject may also learn other rules in advance.

[0134] (3-3) When measuring weight, body composition, standing balance and cardiovascular status, the subject widens the gap between the toe side of the left foot and the toe side of the right foot and places the left and right feet on the surface of the bio-information measuring device 1.

[0135] (3-4) When measuring weight and body composition, the subject places his left and right feet parallel and puts them on the surface of the bio-information measuring device 1.

[0136] The subject can also operate the operation unit 11 to set at least one of the multiple measurement items to the biometric information measuring device 1. Furthermore, the subject can also operate the information processing device to set at least one of the multiple measurement items to the biometric information measuring device 1. For example, as a measurement item where the subject widens the gap between the toes of their left and right feet and places both feet on the surface of the biometric information measuring device 1, measurement items for weight, body composition, standing balance, and cardiovascular status can be set to the biometric information measuring device 1. For example, as a measurement item where the subject places both feet parallel on the surface of the biometric information measuring device 1, measurement items for weight and body composition can be set to the biometric information measuring device 1.

[0137] The configuration sensing unit 53 can also sense (determine) the configuration of the subject's feet on the surface of the biometric information measuring device 1 based on the measurement value output from the electrode unit 21. The configuration sensing unit 53 can also sense (determine) the configuration of the subject's feet on the surface of the biometric information measuring device 1 by determining two electrodes among the plurality of electrodes disposed on the surface of the biometric information measuring device 1 that become conductive through contact with the subject's feet.

[0138] Figure 18 The diagram schematically illustrates the state of the subject's left and right feet on the surface of the biometric information measuring device 1. The subject's left foot is in contact with electrodes 12A and 14, thus electrodes 12A and 14 are in a conductive state. The subject's right foot is in contact with electrodes 13A and 15, thus electrodes 13A and 15 are in a conductive state. The configuration sensing unit 53 determines that the configuration of the subject's feet on the surface of the biometric information measuring device 1 is a first configuration. In this case, the configuration sensing unit 53 outputs the sensing result that the configuration of the subject's feet on the surface of the biometric information measuring device 1 is the first configuration.

[0139] Figure 19 The diagram schematically illustrates the state of the subject's left and right feet on the surface of the biometric information measuring device 1. The subject's left foot is in contact with electrodes 12B and 14, thus electrodes 12B and 14 are in a conductive state. The subject's right foot is in contact with electrodes 13B and 15, thus electrodes 13B and 15 are in a conductive state. The configuration sensing unit 53 determines that the configuration of the subject's feet on the surface of the biometric information measuring device 1 is a second configuration. In this case, the configuration sensing unit 53 outputs the sensing result that the configuration of the subject's feet on the surface of the biometric information measuring device 1 is a second configuration.

[0140] The configuration sensing unit 53 senses the configuration of the subject's feet on the surface of the biometric information measuring device 1 and outputs the sensing results. Based on the sensing results of the configuration sensing unit 53, the measuring unit 42 can select at least one of a plurality of measuring items related to the subject's biometrics and measure the subject's biometric information.

[0141] The rules (3-1) and (3-2) above are explained in the case of the biological information measuring device 1. When the sensing result of the configuration sensing unit 53 indicates that the configuration of the subject's feet is the first configuration, the measuring unit 42 can select all of the multiple measuring items related to the subject's biological information to measure the subject's biological information.

[0142] If the sensing result of the configuration sensing unit 53 indicates that the foot configuration of the subject is the second configuration, the measurement unit 42 can select the measurement item of measuring weight and the measurement item of measuring body composition from among multiple measurement items related to the subject's organism to measure the subject's biometric information. Alternatively, the measurement unit 42 can perform the following processing instead of this processing: The measurement unit 42 can also select the measurement item of measuring weight from among multiple measurement items related to the subject's organism to measure the subject's biometric information. Since only the subject's weight is measured, and other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biometric information is shortened. The measurement unit 42 can also select the measurement item of measuring weight and the measurement item of measuring standing balance from among multiple measurement items related to the subject's organism to measure the subject's biometric information. Since only the subject's weight and standing balance are measured, and other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biometric information is shortened. The measurement unit 42 can also select from multiple measurement items related to the subject's organism to measure weight, body composition, and standing balance to measure the subject's biological information. Since the subject's weight, body composition, and standing balance are measured, while other measurement items are not measured, the time from the start to the completion of the measurement of the subject's biological information is shortened.

[0143] Instead of the rules (3-1) and (3-2) above, the rules (4-1) and (4-2) below can also be set in the biological information measuring device 1. The rules (4-1) and (4-2) below are examples, and other rules can also be set in the biological information measuring device 1.

[0144] (4-1) Measure the weight of the subject with the feet in the first configuration.

[0145] (4-2) With the subject's feet in the second configuration, measure the subject's weight, body composition, standing balance and cardiovascular status.

[0146] Instead of rules (3-3) and (3-4) above, the test subject may also have prior knowledge of rules (4-3) and (4-4) below. Rules (4-3) and (4-4) below are examples; the test subject may also have prior knowledge of other rules.

[0147] (4-3) When measuring body weight, the subject widens the gap between the toe side of the left foot and the toe side of the right foot and places the left and right feet on the surface of the bio-information measuring device 1.

[0148] (4-4) When measuring weight, body composition, standing balance and cardiovascular status, the subject places his left and right feet parallel on the surface of the bio-information measuring device 1.

[0149] exist Figures 17-19 In the biometric information measuring device 1 shown, when the subject changes the measuring direction after stepping onto the surface of the biometric information measuring device 1, the subject does not need to move their feet significantly or re-step onto the surface of the biometric information measuring device 1. The subject can change the foot configuration by moving the toes with minimal effort. By providing a curved recessed portion on electrode 14, the left foot can be easily rotated and moved using the heel of the left foot as a fulcrum. By providing a curved recessed portion on electrode 15, the right foot can be easily rotated and moved using the heel of the right foot as a fulcrum.

[0150] Figure 20 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. Figure 20 The diagram of the operating part 11 and electrodes 12-15 is omitted. Figure 20 In this device, an LED or similar illuminated portion is provided in area E1 on the surface of the biometric information measuring device 1. This illuminated portion in area E1 can be turned on, flashed, and turned off. By illuminating or flashing this portion in area E1, a W-shaped display pattern (representing weight) is displayed on the surface of the biometric information measuring device 1. For example, when measuring the weight of a subject by widening the gap between the toes of their left and right feet, a W-shaped display pattern is displayed on the surface of the biometric information measuring device 1. This allows the subject's left and right feet to be consciously guided towards the W-shaped display pattern on the surface of the biometric information measuring device 1.

[0151] Figure 21 This is a schematic diagram of the biological information measuring device 1 according to the embodiment. Figure 21 The biometric information measuring device 1 shown 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. Electrodes 12C, 12F, and 14A-14D are used to determine the continuity state when the subject's left foot is on the surface of the biometric information measuring device 1. Electrodes 13C, 13F, and 15A-15D are used to determine the continuity state when the subject's right foot is on the surface of the biometric information measuring device 1. (Relative to...) Figure 17The electrode configuration of the biological information measuring device 1 shown, by configuring multiple slender electrodes, can, as Figure 21 The suppression device is enlarged, as shown in the biological information measuring device 1.

[0152] Depending on the boarding method sensed by the sensing unit 41, the measurement unit 42 may take different amounts of time to measure the subject's biometric information. The measurement time for biometric information is explained as follows: The measurement time for biometric information related to weight and body composition (weight and body composition) is longer than the measurement time for biometric information related to weight (weight). The measurement time for biometric information related to weight and standing balance (weight and standing balance) is longer than the measurement time for biometric information (weight). The measurement time for biometric information related to weight, body composition, standing balance, and cardiovascular status (weight, body composition, standing balance, and cardiovascular status) is longer than the measurement time for biometric information (weight and body composition). The measurement time for biometric information (weight, body composition, standing balance, and cardiovascular status) is longer than the measurement time for biometric information (weight and standing balance). When measuring the subject's biometric information by selecting at least one of multiple measurement items based on the boarding method sensed by the sensing unit 41, the measurement time of the measuring unit 42 for measuring the subject's biometric information varies for each measurement item.

[0153] The measuring unit 42 can also set the time for measuring the subject's biological information based on the boarding method sensed by the sensing unit 41. When selecting a cardiovascular status measurement item to measure the subject's biological information, a first predetermined time can be set as the measurement time, or a second predetermined time longer than the first predetermined time can be set as the measurement time. By setting the second predetermined time as the measurement time, the measuring unit 42 can collect more detailed data compared to setting the first predetermined time.

[0154] The measurement unit 42 can also set the measurement time for the subject's biometric information based on the sensing results of the sequence sensing unit 51. For example, if the subject places their left foot on the surface of the biometric information measurement device 1 and then their right foot on the surface of the biometric information measurement device 1, the measurement unit 42 can set a first predetermined time as the measurement time for biometric information and select a cardiovascular status measurement item to measure the subject's biometric information. For example, if the subject places their right foot on the surface of the biometric information measurement device 1 and then their left foot on the surface of the biometric information measurement device 1, the measurement unit 42 can set a second predetermined time as the measurement time for biometric information and select a cardiovascular status measurement item to measure the subject's biometric information. The measurement unit 42 can also set the measurement time for the subject's biometric information based on the sensing results of the direction sensing unit 52. The measurement unit 42 can also set the measurement time for the subject's biometric information based on the sensing results of the configuration sensing unit 53.

[0155] 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 can also be transmitted to the information processing device of the subject via the communication unit 26. The measurement results of the biological information can also be stored in the storage unit of the subject's information processing device. Depending on the boarding method sensed by the sensing unit 41, the object on which the biological information measurement results are recorded can also be different. The measurement unit 42 can also determine whether to record the biological information measurement results based on the sensing results of the sensing unit 41.

[0156] The measurement unit 42 can also determine whether to record the measurement results based on the sensing results of the sequence sensing unit 51. For example, if the subject places their left foot on the surface of the biometric information measuring device 1 and then their right foot on the surface of the biometric information measuring device 1, the measurement unit 42 selects the weight measurement item, measures the subject's biometric information, and records the measurement results in the database of the storage unit 27. For example, if the subject places their right foot on the surface of the biometric information measuring device 1 and then their left foot on the surface of the biometric information measuring device 1, the measurement unit 42 selects the weight measurement item, measures the subject's biometric information, but does not record the measurement results in the database of the storage unit 27. The measurement unit 42 can also determine whether to record the measurement results based on the sensing results of the direction sensing unit 52. The measurement unit 42 can also determine whether to record the measurement results based on the sensing results of the configuration sensing unit 53.

[0157] The measurement unit 42 can also determine whether to record at least one measurement result among multiple measurement items based on the sensing results of the sequence sensing unit 51. For example, if the subject places their left foot on the surface of the biometric information measuring device 1 and then their right foot on the surface of the biometric information measuring device 1, the measurement unit 42 selects measurement items for weight, body composition, standing balance, and cardiovascular status. The measurement unit 42 measures the subject's biometric information and records the measurement results of at least one of the measurement items for weight, body composition, standing balance, and cardiovascular status in the database of the storage unit 27. For example, if the subject places their right foot on the surface of the biometric information measuring device 1 and then their left foot on the surface of the biometric information measuring device 1, the measurement unit 42 selects measurement items for weight, body composition, standing balance, and cardiovascular status. The measurement unit 42 measures the subject's biometric information but does not record the measurement results for the measurement items for weight, body composition, standing balance, and cardiovascular status in the database of the storage unit 27. The measurement unit 42 can also determine whether to record measurement results based on the sensing results of the direction sensing unit 52. The measuring unit 42 can also determine whether to record the measuring results based on the sensing results of the configured sensing unit 53.

[0158] When measuring the biological information of the subject across all measurement items related to the subject's organism, the display unit 10 may not display any information during the measurement processing performed by the measurement unit 42. The subject's actions in observing the information displayed on the display unit 10 (such as foot movements) affect the measurement of cardiovascular status. By not displaying information during the measurement processing performed by the measurement unit 42, the subject's body movements can be suppressed, thus improving the accuracy of cardiovascular status measurement.
