Patent document 2 discloses a technology for automatically determining whether an individual is a human or an animal based on the contact state between the sole of the individual's foot and a measuring electrode, measuring the impedance according to each individual, and calculating body composition data based on the impedance.

LITERATURE LIST Patent literature Patent Literature 1: JP 2005-230120 A Patent Literature 2: JP 2005-230392 A Patent Literature 3: JP 2014-507213 A Patent Literature 4: JP 2002-238870 A BRIEF DESCRIPTION OF THE INVENTION Technical Problem

[0003] A general body composition measuring device includes a load cell and an electrode assembly that comes into contact with the human body, performing a weight measurement or a bioelectrical impedance measurement, and displaying a result regarding body weight or various body compositions. The time required for such measurements is several seconds. Thus, the measurement result is not significantly affected by the individual's body movements, such as head movements for purposes like checking the measurement progress displayed on the foot end during the measurement.On the other hand, if a function for performing a ballistocardiogram (BCG) measurement from a load cell and an impedance pulse wave (IPG) measurement from an electrode, and for displaying cardiovascular status information to a user, is added to the body composition meter, body movement, such as head or arm movement during the measurement, significantly affects the measurement result. This can result in a longer measurement time or necessitate a remeasurement due to the resulting measurement error. A data acquisition series in the body composition meter runs simultaneously, and the results of all measurements are displayed sequentially in typical configurations after a predetermined measurement time has elapsed. Therefore, as the number of measurements increases, a considerable measurement time, including the time required to display the results, is required.However, if a body composition meter is shared by family members, it may be the case that only the body weight value is an administrative goal, and the measurement target is limited to body weight. For example, if a dedicated body weight button is provided on a body composition meter as described in patent literature 4, the dedicated body weight button must be added, and button operation before measurement is cumbersome, resulting in poor usability. Additionally, if only body weight is to be measured, the individual is expected to stand on the body composition meter wearing socks. In this case, the individual's bioelectrical impedance cannot be measured, and a measurement error occurs, resulting in impaired usability.

[0004] The present invention was made in light of the above circumstances, and one of its objectives is to improve the user-friendliness in the measurement of biological information. Solution to the problem

[0005] One aspect of the present invention provides a biological information measuring device with a placement surface configured to allow the placement of an individual, wherein the biological information measuring device includes: a first measuring unit configured to perform at least one of a first measurement process of measuring a condition of a sole of a foot of the individual placed on the placement surface, or a second measurement process of measuring a body movement of the individual placed on the placement surface; and a second measuring unit configured to select at least one measurement quantity from a plurality of measurement quantities relating to the body of the individual based on at least one measurement result of the first measurement process or a measurement result of the second measurement process, and to measure biological information of the individual.According to the biological information measuring device, at least one measurement parameter is selected from the multitude of measurement parameters relating to the individual's body according to the condition of the sole of the individual's foot and the individual's body movement, and the individual's biological information is measured, thus improving the ease of use in measuring biological information.

[0006] The multiple measurement parameters include a sensor for measuring the weight of the individual placed on the placement surface, a sensor configured to measure the body movement of the individual on the placement surface, and a sensor configured to measure the weight of the individual on the placement surface, all configured as a single, combined sensor. This allows for cost reduction.

[0007] The variety of measurands includes one that is measured using a sensor configured to detect the body movement of the individual placed on the placement surface. The sensor configured to measure the individual's body movement can be a load cell. Quantities measured using the load cell include weight, balance in a standing position, and cardiovascular status. Balance in a standing position, for example, is the individual's equilibrium while standing.

[0008] The first measurement unit performs the first measurement process and the second measurement process. If the measurement result of the first measurement process includes a result indicating that the individual is not barefoot and a result indicating an interruption of the individual's motionless state, the second measurement unit selects a measure for weight from the multitude of measures and thus measures the individual's biological information. Because only the individual's weight is measured and no measurement is performed for the other measures, the time from the start to the completion of the measurement of the individual's biological information is reduced.

[0009] The first measurement unit performs the first measurement process and the second measurement process. If the measurement result of the first measurement process includes a result indicating that the individual is barefoot and a result indicating an interruption of an immobile state of the individual, the second measurement unit selects at least one measurement from the multitude of measurable quantities that can be measured in a state in which the individual is not immobile and measures the biological information of the individual. Examples of measurable quantities that can be measured in a state in which the individual is not immobile include, for example, a measurement for measuring weight and a measurement for measuring body composition.Since the weight and body composition of the individual are measured, and no measurement is performed for the other parameters, the time from the start to the completion of the measurement of the individual's biological information is reduced.

[0010] The first measuring unit performs the first measurement process and the second measurement process. If the measurement result of the first measurement process includes a result indicating that the individual is not barefoot and a result indicating that the individual is continuously in a motionless state, the second measuring unit selects at least one measurand from the multitude of measurands that can be measured without using a bioelectrical impedance measurement result and measures the biological information of the individual. The measurands that can be measured without using the bioelectrical impedance measurement result are the measurand for measuring weight and the measurand for measuring balance in a standing position.Since the weight and balance of the individual are measured in a standing position and no measurement is performed for the other parameters, the time from the start to the completion of the measurement of the individual's biological information is reduced.

[0011] The first measuring unit performs the first measurement process and the second measurement process. If the measurement result of the first measurement process includes a result indicating that the individual is barefoot, and the measurement result of the second measurement process includes a result indicating that the individual is continuously in a motionless state, the second measuring unit selects all of the multitude of measurable quantities and measures the individual's biological information. If the individual is on the placement surface of the biological information measuring device while barefoot, and the individual is continuously in a motionless state, the measurement of the individual's biological information is performed under the assumption that the individual intends to measure all of the multitude of measurable quantities.

[0012] The biological information measurement device includes a display unit configured to show information, but this display unit does not show the information while a measurement process is being performed by the second unit. Movement by the individual to view the information displayed on the display unit, such as head movements, affects the measurement of cardiovascular status. By suppressing the individual's body movement and improving the measurement accuracy of the cardiovascular status system, the display unit does not show any information while the second unit is performing the measurement process.

[0013] The biological information measuring device includes a temperature measuring unit configured to measure the temperature of the sole of the individual's foot placed on the placement surface, wherein, if the temperature of the individual's foot is equal to or lower than a predetermined temperature, the first measuring unit performs the second measuring process, and the second measuring unit selects at least one measurable quantity that can be measured without using a bioelectrical impedance measurement result from the multitude of measurable quantities and measures the biological information of the individual based on the measurement result of the second measuring process.If the sole of the individual's foot, placed on the surface of the biological information measuring device, is at a low temperature, the accuracy of the measurement using multiple electrodes will be affected, and it may be incorrectly determined that the individual is not barefoot, even though the individual is. If the temperature of the sole of the individual's foot, placed on the surface of the biological information measuring device, is equal to or lower than the predetermined temperature, the first measuring unit will not perform the initial measurement, thus preventing this erroneous determination.

[0014] It should be noted that the present invention can also be understood as a method for measuring biological information in which a computer performs at least part of the aforementioned processing, a method for measuring biological information which includes at least part of the aforementioned processing, a program for causing a computer to perform at least part of the aforementioned processing, or a computer-readable recording medium on which such a program is non-transiently recorded. It should be noted that the configurations and processes described above can be combined to constitute the present invention, provided that the combination does not lead to technical contradictions. Advantageous effects of the invention

The control unit 20 can be a dedicated device or a general-purpose computer. The control unit 20 includes hardware resources such as a central processing unit (CPU), main memory, and data storage. The main memory can be random-access memory (RAM). The data storage can be a non-volatile data storage device such as read-only memory (ROM) or flash memory. The functions of the control unit 20 as the processing units (functional units) are realized by loading a program stored in the data storage into main memory and executing the program with a processor. The configuration of the control unit 20 is not limited to the above.For example, the functions of the control unit 20 can be configured fully or partially by a circuit such as an ASIC or an FPGA, or the functions of the control unit 20 can be executed fully or partially by a cloud server or another device.

[0023] The electrode unit 21 includes the current supply electrodes 12 and 13 for applying a constant current to the individual's body to measure the individual's bioelectrical impedance, and voltage measuring electrodes 14 and 15 for measuring a voltage during current supply. The electrode unit 21 may include other electrodes that differ from the current supply electrodes 12 and 13 and the voltage measuring electrodes 14 and 15. The impedance measuring unit 22 measures the individual's bioelectrical impedance based on the values ​​of the current applied to the individual's body by the current supply electrodes 12 and 13 and the voltage measured by the voltage measuring electrodes 14 and 15.

[0025] Fig. Figure 3 is a view illustrating an arrangement of multiple load cells. As shown in Fig. As illustrated in Figure 3, load cells 31 to 34 are arranged on the rear of the biological information measuring device 1. The load cells 31 to 34 are each located at four corners on the rear of the biological information measuring device 1. The second sensor unit 24 can include an accelerometer. The second sensor unit 24 can output the measured value from the accelerometer to the control unit 20.

[0026] Fig. Figure 4 is a view illustrating an arrangement of the multiple load cells and an accelerometer. As shown in Fig. As illustrated in Figure 4, load cells 31 to 34 and an accelerometer 35 are arranged on the rear side of the biological information measuring device 1. The load cells 31 to 34 are each located at four corners on the rear side of the biological information measuring device 1. The accelerometer 35 is located in a central section of the rear side of the biological information measuring device 1.

[0027] The temperature measuring unit 25 measures the temperature of the sole of the individual's foot on the surface of the biological information measuring device 1. The temperature measuring unit 25 includes a temperature sensor. The temperature sensor is located on the surface of the biological information measuring device 1. The temperature sensor can be located near the current supply electrodes 12 and 13 or near the voltage measuring electrodes 14 and 15. The communication unit 26 is an interface for conducting wired or wireless communication. The communication unit 26 communicates with an information processing device of the individual. The information processing device is, for example, a portable device, a smartphone, a tablet, a personal computer, or the like.

The data storage device can be a non-volatile data storage device, such as ROM or flash memory. The data storage unit 27 stores various types of information, such as the individual's personal data and a measurement result from the biological information measuring device 1. The personal data is used when calculating the individual's body composition. The personal data includes at least the individual's height and weight and may further include the individual's age and sex, as well as other types of information. The individual's weight is measured when the individual comes into contact with the surface of the biological information measuring device 1.When the individual operates the control unit 11, the individual's height, age, sex and other types of information are entered into the biological information measuring device 1.

[0029] Fig. Figure 5 is a block diagram illustrating a functional configuration of the control unit 20. The control unit 20 includes a first measuring unit 41 and a second measuring unit 42. The first measuring unit 41 includes a sole condition measuring unit 51 and a body movement measuring unit 52. The second measuring unit 42 includes a weight measuring unit 53, a body composition measuring unit 54, a unit 55 for measuring balance in a standing position, and a unit 56 for cardiovascular measurement.

[0030] The sole condition measurement unit 51 measures the condition of the sole of the individual's foot, which is placed on the surface of the biological information measuring device 1, based on a reading output from at least one of the electrode unit 21 or the first sensor unit 23. The body movement measurement unit 52 measures the body movement of the individual on the surface of the biological information measuring device 1 based on a reading output from at least one of the first sensor unit 23, the second sensor unit 24, or the electrode unit 21. The weight measurement unit 53 measures the weight of the individual on the surface of the biological information measuring device 1 based on a reading output from the second sensor unit 24.

[0031] The body composition measurement unit 54 measures the body composition of an individual placed on the surface of the biological information measuring device 1 based on the individual's personal data, the bioelectrical impedance output by the impedance measurement unit 22, and the individual's weight, according to a predetermined algorithm. Body composition is an indicator that specifies the percentage or amount of tissue that constitutes the body. Examples of body composition include, but are not limited to, body fat percentage, amount of visceral fat, skeletal muscle percentage, basal metabolic rate, body age, BMI, muscle percentage, muscle mass, body fat mass, bone mass, water content, and the like. The individual's personal data includes weight and previously measured bioelectrical impedance.The body composition measurement unit 54 can identify the individual by comparing previously measured weight and bioelectrical impedance with the currently measured weight and bioelectrical impedance. The body composition measurement unit 54 retrieves the identified individual's personal data from the data storage unit 27.

[0032] The Unit 55 for measuring balance in a standing position measures the balance of the individual while standing on the surface of the measuring device 1 for biological information (balance in a standing position) based on the measurement output by the second sensor unit 24. The Unit 55 for measuring balance in a standing position can measure the balance of the individual by calculating the position of the individual's center of gravity in the standing position. The Unit 55 for measuring balance in a standing position can measure the balance of the individual according to a predetermined algorithm.

[0033] The Cardiovascular Measurement Unit 56 measures the individual's cardiovascular status on the surface of the biological information measuring device 1 based on the reading output from the second sensor unit 24 and the bioelectrical impedance output from the impedance measuring unit 22, according to a predetermined algorithm. The Cardiovascular Measurement Unit 56 measures a ballistocardiogram (BCG), which is a vibration caused by the blood pumped from the heart, based on the reading output from the second sensor unit 24. The Cardiovascular Measurement Unit 56 measures the leg impedance pulse wave (IPG) and the foot impedance pulse wave (IPG) based on the bioelectrical impedance output from the impedance measuring unit 22. Leg IPG is an indicator that specifies a change in the amount of blood in a blood vessel of the leg.Foot IPG is an indicator that specifies a change in blood volume in a blood vessel of the foot. Unit 56 for cardiovascular measurement generates a mean waveform of the foot IPG (foot IPG waveform) relative to the leg IPG. Unit 56 for cardiovascular measurement calculates a pulse transit time (PTT) from the BCG waveform and a feature point of the foot IPG waveform.

[0034] Fig. Figure 6 is a diagram illustrating the relationship between the BCG waveform, the foot-IPG waveform, and the PTT. As shown in Fig. As illustrated in Figure 6, the pulse transit time (PTT) can be calculated by obtaining a (time) difference between a reference point of the BCG waveform and the feature point of the foot IPG waveform. The Unit 56 Cardiovascular Measurement calculates pulse wave velocity (PWV) by dividing a measurement range distance by the PTT. Since the PWV value increases as the blood vessel becomes stiffer, PWV is used as an indicator that specifies the stiffness of the blood vessel. The Unit 56 Cardiovascular Measurement converts the pulse wave velocity (PWV) into an indicator (cardiovascular indicator) that specifies cardiac function or the condition of a blood vessel, based on a predetermined algorithm, and calculates the cardiovascular indicator.To measure an individual's cardiovascular status, it is necessary to maintain a state of either no or minimal body movement for approximately 20 to 30 seconds. Therefore, Unit 56 for cardiovascular measurement begins measuring an individual's cardiovascular status when the individual is either completely still or minimally moving.

[0035] A first operation of the measuring device 1 for biological information is carried out with reference to Fig. 7 described. Fig. Figure 7 is a flowchart illustrating the initial operation of the biological information measuring device 1. For example, when an initial operating mode is set for the biological information measuring device 1, the control unit 20 reads the program stored in the data storage unit 27, thereby performing the individual processes in the flowchart of Fig. 7 will be executed.

[0036] In step S101, the individual presses switch 110 of the biological information measuring device 1 to turn on the power supply to the biological information measuring device 1. The power supply to the biological information measuring device 1 can be turned on when the individual reaches the surface of the biological information measuring device 1 in step S101.

[0037] In step S102, the sole condition measuring unit 51 measures the condition of the individual's foot, which is placed on the surface of the biological information measuring device 1, based on a reading output from at least one of the electrode unit 21 or the first sensor unit 23, and determines whether the individual is barefoot. If the individual is not barefoot (step S102; NO), the process proceeds to step S103. If the individual is barefoot (step S102; YES), the process proceeds to step S106.

[0038] The process of determining whether an individual is barefoot is described. This process can be carried out by arranging a plurality of electrodes on the front and back surfaces of the biological information measuring device 1 and measuring the resistance between the electrodes. The electrode assembly 21 can include a plurality of electrodes 31. The front surface of the biological information measuring device 1 is the toe side of the individual's foot when the individual's foot is placed on the surface of the biological information measuring device 1. The back surface of the biological information measuring device 1 is the heel side of the individual's foot when the individual's foot is placed on the surface of the biological information measuring device 1.When the individual is wearing socks, there is no difference between the resistance value between the two electrodes located on the front surface of the biological information measuring device 1 and the resistance value between the two electrodes located on the back surface of the biological information measuring device 1. The sole condition measuring unit 51 can perform the process of determining whether the individual is barefoot by measuring the resistance value between two electrodes located on the front surface of the biological information measuring device 1 and the resistance value between two electrodes located on the back surface of the biological information measuring device 1.One of the two electrodes located on the front surface of the biological information measuring device 1 can be the current supply electrode 12 or 13. One of the two electrodes located on the back surface of the biological information measuring device 1 can be the voltage measuring electrode 14 or 15.

[0039] Fig. Figure 8 is a view illustrating a schematic configuration of a measuring device 1 for biological information according to the present embodiment. As shown in Fig. As illustrated in Figure 8, an auxiliary electrode 60 can be arranged on the front surface of the biological information measuring device 1. The sole condition measuring unit 51 can perform the process of determining whether the individual is barefoot by measuring the resistance value between the current supply electrode 12 and the auxiliary electrode 60, and the resistance value between the voltage measuring electrode 14 and the auxiliary electrode 60. The auxiliary electrode 60 can be attached not only to the surface of the device 1, but also to the surface of the sole condition measuring unit 51. Fig. The auxiliary electrode 60 can be arranged not only in the position illustrated in Figure 8, but also at any position between the current supply electrode 12 and the voltage measuring electrode 14. The auxiliary electrode 60 can be arranged at any position between the current supply electrode 13 and the voltage measuring electrode 15. Since the plantar arch portion of the individual's sole is unlikely to come into contact with the auxiliary electrode 60, it is not preferable to position the auxiliary electrode 60 at a location corresponding to the plantar arch portion of the individual's sole. In general, the heel side of the individual's foot is stiffer than the toe side, and the difference between the resistance value of the toe side and the resistance value of the heel side of the individual's foot is large.If, however, the individual is wearing footwear such as socks, the difference between the resistance value on the toe side of the individual's foot and the resistance value on the heel side of the individual's foot is small. If the difference (difference value) between the resistance value on the toe side of the individual's foot and the resistance value on the heel side of the individual's foot is equal to or greater than the threshold value, the sole condition measurement unit 51 determines that the individual is barefoot. If the difference (difference value) between the resistance value on the toe side of the individual's foot and the resistance value on the heel side of the individual's foot is less than the threshold value, the sole condition measurement unit 51 determines that the individual is not barefoot.

[0040] A photoelectric sensor can be arranged on the surface of the measuring device 1 for biological information, and the amount of light received by the photoelectric sensor can be measured to carry out the process of determining whether the individual is barefoot. Fig. Figure 9 is a view illustrating the arrangement of a photoelectric sensor. In the Fig. In the illustrated example 9, a photoelectric sensor 70 is arranged between the current supply electrode 12 and the voltage measuring electrode 14. The first sensor unit 23 can enclose the photoelectric sensor 70.

[0041] The photoelectric sensor 70 is preferably arranged near the current supply electrode 12 so that the photoelectric sensor 70 reliably comes into contact with the sole of the individual's foot when the individual steps onto the surface of the biological information measuring device 1. For example, the photoelectric sensor 70 can be arranged near the current supply electrode 12 so that the photoelectric sensor 70 comes into contact with the ball of the individual's big toe. The photoelectric sensor 70 can be located in an area between a dashed line A1 in Fig. 9 and the current supply electrode 12.

[0042] The photoelectric sensor 70 can be arranged near the voltage measuring electrode 14. The photoelectric sensor 70 can be located in an area between a dashed line A2 in Fig. The photoelectric sensor 70 can be arranged between the current supply electrode 13 and the voltage measuring electrode 14. The photoelectric sensor 70 can be arranged near the current supply electrode 13. The photoelectric sensor 70 can be located in an area between a dashed line A3 in Fig. The photoelectric sensor 70 can be arranged near the voltage measuring electrode 15. The photoelectric sensor 70 can be located in an area between a dashed line A4 in Fig. 9 and the voltage measuring electrode 15. A plurality of the photoelectric sensors 70 can be arranged on the surface of the measuring device 1 for biological information. The fabric of the sock is thin in a rubbed area such as the heel. To avoid an incorrect measurement, the photoelectric sensor 70 can be arranged on the back of the surface of the measuring device 1 for biological information.

[0043] Fig. 10 to Fig. Figure 12 are diagrams illustrating a case in which the amount of light received by the photoelectric sensor is measured to determine whether an individual is barefoot. Fig. 10 and Fig. Figure 11 illustrates the measuring device 1 for biological information viewed from the side. The photoelectric sensor 70 includes a light-emitting diode (LED) 71, which is a light-emitting unit that generates light, and a photodiode 72, which is a light-receiving unit that receives light. The light emitted by the LED 71 is preferably in a wavelength band that is not readily absorbed by living body tissue (for example, 500 nm to 1000 nm including these two values). Fig. Figure 10 illustrates the biological information measuring device 1 in a case where a sock-wearing individual is on the surface of the biological information measuring device 1. Fig. Figure 11 illustrates the biological information measuring device 1 in a case where an individual not wearing socks is on the surface of the biological information measuring device 1. Fig. Figure 12 illustrates a value (voltage value) obtained by converting the amount of light received by photodiode 72 into voltage. The vertical axis in Fig. 12 represents the voltage value and the horizontal axis in Fig. 12 represents time.

[0044] A in Fig. 12. Illustrated voltage value V1 is a voltage value obtained when the individual located on the surface of the biological information measuring device 1 is wearing socks. A Fig. The illustrated voltage value V2 is a voltage value obtained when the individual, located on the surface of the biological information measuring device 1, is not wearing socks. The blood vessels on the body surface are compressed by the sole of the individual's foot, which bears the body weight. When the individual is not wearing socks, the light emitted by LED 71 reaches photodiode 72 with little attenuation. When the individual is wearing socks, the light emitted by LED 71 reaches photodiode 72 with attenuation by the socks. Therefore, the voltage value V1 is lower than the voltage value V2.

[0045] If the voltage value is equal to or greater than a threshold value TH1, the sole condition measuring unit 51 determines that the individual is barefoot. If the amount of light received by the photodiode 72 is equal to or greater than the threshold value, the sole condition measuring unit 51 can determine that the individual is barefoot. The sole condition measuring unit 51 outputs a measurement result that includes a result indicating that the individual is barefoot.

[0046] If the voltage value is less than the threshold TH1, the sole condition measuring unit 51 determines that the individual is not barefoot. If the amount of light received by the photodiode 72 is less than the threshold, the sole condition measuring unit 51 can determine that the individual is not barefoot. The sole condition measuring unit 51 outputs a measurement result that includes a result indicating that the individual is not barefoot.

[0047] A number of the photoelectric sensors 70 can be arranged on the surface of the biological information measuring device 1. For example, the photoelectric sensor 70 for measuring the condition of the sole of the individual's left foot and the photoelectric sensor 70 for measuring the condition of the sole of the individual's right foot can be arranged on the surface of the biological information measuring device 1.

[0048] In step S103, the body motion measurement unit 52 measures the body motion of the individual on the surface of the biological information measuring device 1 based on the measurement output from at least one of the first sensor unit 23, the second sensor unit 24, or the electrode unit 21, and determines whether the individual's body motion is large. That is, the body motion measurement unit 52 measures the individual's body motion on the surface of the biological information measuring device 1 and determines whether the individual is continuously in a motionless state. The motionless state is a state in which the fluctuation of the measurement output from the first sensor unit 23, the second sensor unit 24, or the electrode unit 21 does not reach a predetermined value.

[0049] The process of determining whether an individual's body movement is large is described. When the individual's foot moves on the surface of the biological information measuring device 1, the measurement output by the first sensor unit 23 fluctuates. The measurement output by the first sensor unit 23 is, for example, a voltage value or the amount of light received by the photodiode 72. If the measurement output by the first sensor unit 23 fluctuates continuously for a predetermined period, the body movement measuring unit 52 determines that the individual's body movement is large. The body movement measuring unit 52 can determine that the individual is not continuously in a motionless state if the measurement output by the first sensor unit 23 fluctuates continuously for a predetermined period.The body motion measurement unit 52 outputs a measurement result that includes at least one result indicating that the individual's body motion is large or that the individual is not continuously in the motionless state. If the measurement output by the first sensor unit 23 does not fluctuate continuously over the predetermined period, the body motion measurement unit 52 determines that the individual's body motion is small. The body motion measurement unit 52 can determine that the individual is continuously in the motionless state if the measurement output by the first sensor unit 23 does not fluctuate continuously over a predetermined period.The body motion measurement unit 52 outputs a measurement result that includes at least one of a result indicating that the individual's body motion is low or a result indicating that the individual is continuously in the motionless state.

[0050] When the individual performs a predetermined movement on the surface of the biological information measuring device 1, a large measurement is output by the second sensor unit 24. For example, the predetermined movement is, but is not limited to, the individual moving to see the display unit 10. If the measurement output by the second sensor unit 24 is continuously equal to or greater than the threshold for a predetermined period, the body movement measuring unit 52 determines that the individual's body movement is large. If the mean value of the measurements output by the second sensor unit 24 within the predetermined period is equal to or greater than the threshold, the body movement measuring unit 52 determines that the individual's body movement is large.In these cases, the body motion measurement unit 52 can determine that the individual is not continuously in the motionless state. The body motion measurement unit 52 outputs a measurement result that includes at least one result indicating that the individual's body motion is high or a result indicating that the individual is not continuously in the motionless state. If the measurement output by the second sensor unit 24 is continuously less than the threshold for a predetermined period, the body motion measurement unit 52 determines that the individual's body motion is low. If the mean value of the measurements output by the second sensor unit 24 within the predetermined period is less than the threshold, the body motion measurement unit 52 determines that the individual's body motion is low.In these cases, the body motion measurement unit 52 can determine that the individual is continuously in the motionless state. The body motion measurement unit 52 outputs a measurement result that includes at least one of two results indicating that the individual's body motion is minimal or that the individual is continuously in the motionless state. The threshold used to measure the individual's body motion can be obtained through trial or simulation. For example, the threshold can be determined based on the measurement output by the second sensor unit 24 when the individual makes a movement to view the display unit 10.

[0051] When the individual's foot moves on the surface of the biological information measuring device, the reading output by the electrode unit 21 fluctuates. The reading output by the electrode unit 21 is, for example, a myoelectric reading. If the reading output by the electrode unit 21 fluctuates continuously for a predetermined period, the body motion measuring unit 52 determines that the individual's body motion is significant. The body motion measuring unit 52 can determine that the individual is not continuously in a motionless state if the reading output by the electrode unit 21 fluctuates continuously for a predetermined period.The body motion measurement unit 52 outputs a measurement result that includes at least one of two outcomes: either indicating that the individual's body motion is high or indicating that the individual is not continuously in the motionless state. If the measurement output by the electrode unit 21 does not fluctuate continuously over the predetermined period, the body motion measurement unit 52 determines that the individual's body motion is low. The body motion measurement unit 52 can determine that the individual is continuously in the motionless state if the measurement output by the electrode unit 21 does not fluctuate continuously over a predetermined period.The body motion measurement unit 52 outputs a measurement result that includes at least one of a result indicating that the individual's body motion is low or a result indicating that the individual is continuously in the motionless state.

[0052] If the individual's body movement is large (step S103; YES), the process continues with step S104. If the individual's body movement is small (step S103; NO), the process continues with step S105.

[0054] In step S105, the weight measuring unit 53 measures the weight of the individual on the surface of the biological information measuring device 1 based on the reading output from the second sensor unit 24. In step S105, the balance measuring unit 55 measures the balance of the individual in a standing position on the surface of the biological information measuring device 1 based on the reading output from the second sensor unit 24. In step S105, the display unit 10 shows information on the weight and balance of the individual in a standing position. The information on the balance of the individual in a standing position includes, for example, information indicating the position of the individual's center of gravity in a standing position, but is not limited to this.In step S 105, the information on the individual's weight and balance in a standing position is stored in the data storage unit 27. This information can be transmitted to the individual's information processing device via the communication unit 26. The information is then stored in the data storage unit of the individual's information processing device.

[0055] In step S 106, the body motion measurement unit 52 measures the body motion of the individual on the surface of the biological information measuring device 1 based on the measurement output from at least one of the first sensor unit 23, the second sensor unit 24 or the electrode unit 21, and determines whether the body motion of the individual is large.

[0056] If the individual's body movement is large (step S106; YES), the process continues with step S107. If the individual's body movement is small (step S106; NO), the process continues with step S108.

[0057] In step S107, the weight measurement unit 53 measures the individual's weight on the surface of the biological information measurement device 1 based on the reading output from the second sensor unit 24. In step S107, the body composition measurement unit 54 measures the individual's body composition on the surface of the biological information measurement device 1 based on the bioelectrical impedance output from the impedance measurement unit 22 and the individual's weight. In step S107, the display unit 10 shows information about the individual's weight and body composition.

[0058] In step S107, the information on the individual's weight and body composition is stored in the data storage unit 27. This information can be transmitted to the individual's information processing device via the communication unit 26. The information is then stored in the data storage unit of the individual's information processing device.

[0059] In step S108, the weight measurement unit 53 measures the individual's weight on the surface of the biological information measuring device 1 based on the reading output from the second sensor unit 24. In step S108, the body composition measurement unit 54 measures the individual's body composition on the surface of the biological information measuring device 1 based on the bioelectrical impedance output from the impedance measurement unit 22 and the individual's weight. In step S108, the standing balance measurement unit 55 measures the individual's standing balance on the surface of the biological information measuring device 1 based on the reading output from the second sensor unit 24.In step S108, the cardiovascular measurement unit 56 measures the individual's cardiovascular status on the surface of the biological information measuring device 1 based on the measurement output by the second sensor unit 24 and the bioelectrical impedance output by the impedance measurement unit 22. In step S108, the display unit 10 shows information on the individual's weight, body composition, standing balance, and cardiovascular status. The cardiovascular status information is a cardiovascular indicator but is not limited to this.

[0060] In step S108, the information on the individual's weight, body composition, standing balance, and cardiovascular status is stored in the data storage unit 27. This information can be transmitted to the individual's information processing device via the communication unit 26. The data is then stored in the data storage unit of the individual's information processing device.

[0061] A second operation of the measuring device 1 for biological information is carried out with reference to Fig. 13 described. Fig. Figure 13 is a flowchart illustrating the second operation of the biological information measuring device 1. For example, when a second operating mode is set for the biological information measuring device 1, the control unit 20 reads the program stored in the data storage unit 27, thereby completing the individual processes in the flowchart of Fig. 13 will be executed.

[0062] In step S201, the individual presses switch 110 of the biological information measuring device 1 to turn on the power supply to the biological information measuring device 1. The power supply to the biological information measuring device 1 can be turned on when the individual is placed on the surface of the biological information measuring device 1 in step S201.

[0063] In step S202, the sole condition measuring unit 51 measures the condition of the individual's foot, which is placed on the surface of the biological information measuring device 1, based on a reading output from at least one of the electrode unit 21 or the first sensor unit 23, and determines whether the individual is barefoot. If the individual is not barefoot (step S202; NO), the process proceeds to step S203. If the individual is barefoot (step S202; YES), the process proceeds to step S204.

[0064] In step S203, the weight measuring unit 53 measures the weight of the individual on the surface of the biological information measuring device 1 based on the measurement output by the second sensor unit 24. In step S203, the display unit 10 shows information about the individual's weight. In step S203, the information about the individual's weight is stored in the data storage unit 27. The information about the individual's weight can be transmitted to the individual's information processing device via the communication unit 26. The information about the individual's weight is stored in the data storage unit of the individual's information processing device.

[0065] In step S204, the weight measuring unit 53 measures the individual's weight on the surface of the biological information measuring device 1 based on the reading output from the second sensor unit 24. In step S204, the body composition measuring unit 54 measures the individual's body composition on the surface of the biological information measuring device 1 based on the bioelectrical impedance output from the impedance measuring unit 22 and the individual's weight.

In step S204, the information on the individual's weight and body composition is stored in the data storage unit 27. The information on the individual's weight and body composition can be transmitted to the individual's information processing device via the communication unit 26.The information on the individual's weight and body composition is stored in the data storage unit of the individual's information processing device.

[0066] A third operation of the measuring device 1 for biological information is described with reference to Fig. 14 described. Fig. Figure 14 is a flowchart illustrating the third operation of the biological information measuring device 1. For example, when a third operating mode is set for the biological information measuring device 1, the control unit 20 reads the program stored in the data storage unit 27, thereby completing the individual processes in the flowchart of Fig. 14 will be executed.

[0067] In step S301, the individual presses switch 110 of the biological information measuring device 1 to turn on the power supply to the biological information measuring device 1. The power supply to the biological information measuring device 1 can be turned on when the individual is placed on the surface of the biological information measuring device 1 in step S301.

[0068] In step S302, the body motion measurement unit 52 measures the state of the individual's body motion on the surface of the biological information measuring device 1 based on the measurement output from at least one of the first sensor unit 23, the second sensor unit 24 or the electrode unit 21, and determines whether the individual's body motion is large.

[0069] If the individual's body movement is large (step S302; YES), the process continues with step S303. If the individual's body movement is small (step S302; NO), the process continues with step S304.

[0070] In step S303, the weight measuring unit 53 measures the weight of the individual on the surface of the biological information measuring device 1 based on the measurement output by the second sensor unit 24. In step S303, the display unit 10 shows information about the individual's weight. In step S303, the information about the individual's weight is stored in the data storage unit 27. The information about the individual's weight can be transmitted to the individual's information processing device via the communication unit 26.

This information is then stored in the data storage unit of the individual's information processing device.

[0072] Fig. Figure 15 is a time graph of a process for measuring sole condition, a process for measuring body movement, a process for measuring weight, a process for measuring body composition, a process for measuring balance in a standing position, and a process for measuring cardiovascular condition. The sole condition measurement time is the elapsed time from time (T0) when the individual enters the surface of the biological information measuring device 1 until time (T1) when the sole condition measurement process ends. The body movement measurement time is the elapsed time from time (T0) when the individual enters the surface of the biological information measuring device 1 until time (T1) when the body movement measurement process ends.The weight measurement period is the elapsed time from time (T0) when the individual enters the surface of the biological information measuring device 1 until time (T1) when the weight measurement process ends. The body composition measurement period is the elapsed time from time (T1) until time (T2) when the body composition measurement process ends. The standing balance measurement period is the elapsed time from time (T1) until time (T3) when the standing balance measurement process ends. The cardiovascular status measurement period is the elapsed time from time (T1) until time (T4) when the cardiovascular status measurement process ends.

[0073] The first measuring unit 41 includes the sole condition measuring unit 51 and the body movement measuring unit 52. The first measuring unit 41 performs at least one of the following: either the first measurement process of measuring the condition of the individual's sole of the foot on the surface of the biological information measuring device 1, or the second measurement process of measuring the individual's body movement on the surface of the biological information measuring device 1. When the first operating mode for the biological information measuring device 1 is set, the first measuring unit 41 performs both the first and second measurement processes and outputs the measurement result of the first and second measurement processes. When the second operating mode for the biological information measuring device 1 is set, the first measuring unit 41 performs only the first measurement process and outputs the measurement result of the first measurement process.When the third operating mode is set for the measuring device 1 for biological information, the first measuring unit 41 performs the second measuring process and outputs the measurement result of the second measuring process.

[0074] The second measurement unit 42 includes the weight measurement unit 53, the body composition measurement unit 54, the unit 55 for measuring balance in a standing position, and the unit 56 for cardiovascular measurement. The second measurement unit 42 selects at least one measurement from the multitude of measurements relating to the individual's body based on at least one of the measurement results of the first measurement process or the measurement result of the second measurement process and measures the individual's biological information. The multitude of measurements relating to the individual's body includes a measurement for measuring weight, a measurement for measuring body composition, a measurement for measuring balance in a standing position, and a measurement for measuring cardiovascular status.According to the measuring device 1 for biological information, at least one measurement parameter is selected from the multitude of measurements relating to the individual's body based on the condition of the individual's soles and body movement, and then the individual's biological information is measured, thus improving the user-friendliness of the measurement. With a known body composition measuring device, for example, the individual must be barefoot on the device even when only body weight is to be measured. Therefore, according to the known body composition measuring device, it is necessary to wait until the measurement of the individual's parameters other than weight is completed, thus impairing the user-friendliness of the measurement.

[0075] A sensor can be used both as a sensor for measuring the body movement of an individual on the surface of the biological information measuring device 1 and as a sensor for measuring the individual's weight on the surface of the biological information measuring device 1. For example, using the multiple load cells of the second sensor unit 24, the body movement of an individual on the surface of the biological information measuring device 1 and the individual's weight on the surface of the biological information measuring device 1 can be measured. Using a single sensor that serves both as a sensor for measuring the body movement of an individual on the surface of the biological information measuring device 1 and as a sensor for measuring the individual's weight on the surface of the biological information measuring device 1 can reduce costs.

[0076] The multitude of measurements relating to the individual's body can include a measurement taken using a sensor that detects the individual's body movement on the surface of the biological information measuring device 1. For example, the sensor that detects the individual's body movement on the surface of the biological information measuring device 1 is the multitude of load cells of the second sensor unit 24. The quantities that can be measured using the multitude of load cells of the second sensor unit 24 are the measurement of weight, the measurement of balance in a standing position, and the measurement of cardiovascular status.

[0077] A case in which the first operating mode for measuring device 1 for biological information is set is described. Here, a result indicating that the individual is not barefoot is referred to as result (A), and a result indicating that the individual is barefoot is referred to as result (B). A result indicating that the individual's body movement is large, or a result indicating that the individual is continuously in a motionless state, is referred to as result (C). A result indicating that the individual's body movement is small, or a result indicating that the individual is continuously in a motionless state, is referred to as result (D).

[0078] For example, if the individual is wearing socks and is therefore not barefoot, the accuracy of the bioelectrical impedance measurement is affected. Therefore, in such a case, it is not preferable to measure the individual's body composition and cardiovascular status. It is also not preferable to measure balance in a standing position without the individual being motionless. To measure the individual's cardiovascular status, the individual must remain motionless for 20 to 30 seconds continuously. Therefore, if the measurement result of the first measurement process includes result (A) and the measurement result of the first measurement process includes result (C), the second measurement unit 42 selects the quantity to measure weight from the multitude of measurements relating to the individual's body and measures the individual's biological information.Since only the individual's weight is measured and no measurements are taken for other parameters, the time from the start to the completion of the measurement of the individual's biological information is reduced. Specifically, because sensor output, algorithm processing, display, and data storage processing for the biological information, and the like, are excluded from the measurement of body composition, standing balance, and the individual's cardiovascular status, the time from the start to the completion of the measurement of the individual's biological information is reduced.If the body composition or cardiovascular status of a sock-wearing individual is measured using a known body composition measuring device, an error occurs, for example, in the middle of the measurement, making it impossible to accurately measure the individual's body composition or cardiovascular status. In this case, with the known body composition measuring device, the time from the start to the completion of the measurement of the individual's biological information is extended because a process such as error reporting takes place.

[0079] If the measurement result of the first measurement process includes result (B) and the measurement result of the first measurement process includes result (C), the second measurement unit 42 selects at least one measurement from the multitude of measurements relating to the individual's body that can be measured in a state where the individual is not motionless and measures the individual's biological information. The measurement that can be measured in a state where the individual is not motionless is a measurement for measuring weight and a measurement for measuring body composition. Because the individual's weight and body composition are measured, and no measurement is performed for the other measurements, the time from the start to the completion of the measurement of the individual's biological information is reduced.In particular, since the sensor output, algorithm processing, display and data storage processing for the biological information and the like are excluded from the measurement of the individual's balance in a standing position and cardiovascular condition, the time from the start to the completion of the measurement of the individual's biological information is shortened.

[0080] If the measurement result of the first measurement process includes result (A) and the measurement result of the first measurement process includes result (D), the second measurement unit 42 selects at least one measurand that can be measured without using the bioelectrical impedance measurement result from the multitude of measurands relating to the individual's body and measures the individual's biological information. The measurands that can be measured without using the bioelectrical impedance measurement result are the measurand for measuring weight and the measurand for measuring balance in a standing position. Since the individual's weight and balance are measured in a standing position and no measurement is performed for the other measurands, the time from the start to the completion of the measurement of the individual's biological information is reduced.In particular, since the sensor output, algorithm processing, display and data storage processing for the biological information and the like are excluded from the measurement of the individual's body composition and cardiovascular condition, the time from the start to the completion of the measurement of the individual's biological information is shortened.

[0081] If the measurement result of the first measurement process includes result (B) and the measurement result of the first measurement process includes result (D), the second measurement unit 42 selects all of the multitude of measurements relating to the individual's body and measures the individual's biological information. When the barefoot individual is on the surface of the biological information measuring device 1 and the individual remains continuously motionless, the individual's biological information is measured, assuming the individual intends to measure weight, body composition, standing balance, and cardiovascular status.

[0082] In a scenario where the measurement of an individual's biological information is performed for all of the numerous parameters relating to the individual's body, display unit 10 cannot display the information while the measurement process is being carried out by the second measuring unit 42. The individual's movement to view the information displayed on display unit 10 (moving their feet to see the data) affects the measurement of cardiovascular status. Display unit 10 does not display any information while the measurement process is being carried out by the second measuring unit 42, thus suppressing the individual's body movement and improving the accuracy of the cardiovascular status measurement.

[0083] If the sole of the individual's foot, placed on the surface of the biological information measuring device 1, is at a low temperature, the measurement accuracy of the sole's temperature using the multiple electrodes will be affected, and it may be incorrectly determined that the individual is not barefoot, even though the individual is. Therefore, if the temperature of the sole of the individual's foot on the surface of the biological information measuring device 1 is equal to or lower than a predetermined temperature, the first measuring unit 41 can perform the second measurement process and output the result of the second measurement process.In this case, the second measuring unit 42, based on the measurement result of the second measurement process, selects at least one measurand from the multitude of measurands relating to the individual's body that can be measured without using the bioelectrical impedance measurement result and measures the individual's biological information. Thus, if the temperature of the individual's sole of the foot, which is placed on the surface of the biological information measuring device 1, is equal to or lower than the predetermined temperature, the first measuring unit 41 does not perform the first measurement process, thereby preventing erroneous determinations. The display unit 10 can display a message: "Body composition and cardiovascular status cannot be measured because the sole of the foot is cold."

[0084] In a case where the individual dismounts from the biological information measuring device 1 before the measurement of biological information for some of the parameters selected from the multitude of parameters relating to the individual's body is completed, the measurement result of the biological information measured at the time the individual dismounted from the biological information measuring device 1 can be displayed on the display unit 10. For example, if the individual dismounts between time (T2) and time (T3) in Fig. As the measuring device 1 for biological information descends, the display unit 10 shows the measurement results of the biological information between the start of the measurement of the biological information and the time (T2) in Fig. 15 were measured. For example, if the individual between time (T3) and time (T4) in Fig. As the measuring device 1 for biological information descends, the display unit 10 shows the measurement results of the biological information that were obtained between the start of the measurement of the biological information and time (T3) in Fig. 15 were measured.
