Description

[Technical Field]

[0001] The present invention relates to a biological information measuring device, a biological information measuring method, and a program. [Background technology]

[0002] Patent Documents 1 and 2 disclose an apparatus that acquires a biosignal (IPG, BCG, etc.) using a body weight and composition monitor-type device and outputs a biometric indicator such as vascular elasticity. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-101504 [Patent Document 2] Special Publication No. 2014-507213 Summary of the Invention [Problem to be solved by the invention]

[0004] Typical body composition monitors have a load cell and electrodes that contact the human body. These monitors measure weight and bioimpedance, displaying results related to weight and various body composition parameters. These measurements take only a few seconds, and the subject's head movements during the measurement, such as checking the progress of the measurement displayed at the user's feet, have little effect on the measurement results. However, when a body composition monitor is equipped with functions such as BCG (ballistocardiogram) measurements from the load cell and IPG (impedance pulse wave) measurements from the electrodes to provide the user with cardiovascular status information, head or arm movements during the measurement significantly affect the measurement results, resulting in longer measurement times or even measurement errors requiring remeasurements. For example, if the subject is holding or operating the input device used for the measurement, head or arm movements during the measurement can cause body movements that reduce measurement accuracy.

[0005] The present invention has been made in view of the above circumstances, and has as its object to realize measurements that are desirable for the subject. [Means for solving the problem]

[0006] According to one aspect of the present invention, there is provided a biometric information measuring device comprising: a main body having a support surface on which a subject can stand; a status information acquiring unit acquiring status information of an input device operated by the subject; and a biometric information measuring unit selecting a measurement sequence corresponding to the status information and measuring the biometric information of the subject standing on the support surface. When the subject operates or holds the input device, body movements occur due to the subject moving their head or arms during measurement. The state of the input device is one factor that affects the subject's body movements, and measuring the subject's biometric information according to the state of the input device can improve the measurement accuracy of the biometric information. With the biometric information measuring device, a measurement sequence corresponding to the state information of the input device operated by the subject is selected, and the biometric information of the subject is measured. This allows the biometric information of the subject to be measured taking into account the state of the input device, which is a factor that causes body movements, thereby improving the measurement accuracy of the biometric information. Furthermore, even if the state of the input device changes during measurement, the measurement sequence is changed and selected according to the state information of the input device, and a notification of suppression of body movement is sent to the subject, or measurement items are switched to those less affected by body movement at an early stage. This makes it easier to complete the measurement of biological information, leading to an improved measurement success rate. In this way, it is possible to achieve measurements that are desirable for the subject.

[0007] The state information includes information indicating whether the input device is installed on the main body. The biological information measurement unit measures the biological information of the subject by selecting the measurement sequence corresponding to information indicating that the input device is installed in the main body or information indicating that the input device is not installed in the main body. A measurement sequence corresponding to information indicating that the input device is installed in the main body of the biological information measurement device or information indicating that the input device is not installed in the main body of the biological information measurement device is selected, and the biological information of the subject is measured. By installing the input device in the main body of the biological information measurement device, body movement caused by the subject gripping the input device is suppressed. When a measurement sequence corresponding to information indicating that the input device is installed in the main body of the biological information measurement device is selected, the biological information of the subject is measured with body movement suppressed, thereby improving measurement accuracy. When an input device is not installed in the main body of the biological information measurement device, body movement may occur when the subject grips or operates the input device. When a measurement sequence corresponding to information indicating that the input device is not installed in the main body of the biological information measurement device is selected, redoing the measurement due to body movement is prevented, thereby improving the success rate of the measurement.

[0008] The status information includes information indicating whether the input device is installed in the vicinity of the main body, and the biological information measurement unit selects the measurement sequence corresponding to information indicating that the input device is installed in the vicinity of the main body or information indicating that the input device is not installed in the vicinity of the main body to measure the biological information of the subject. The measurement sequence corresponding to information indicating that the input device is installed in the vicinity of the main body of the biological information measurement device or information indicating that the input device is not installed in the vicinity of the main body of the biological information measurement device is selected to measure the biological information of the subject. By installing the input device in the vicinity of the main body of the biological information measurement device, body movement caused by the subject gripping the input device is suppressed. When a measurement sequence corresponding to information indicating that the input device is installed in the vicinity of the main body of the biological information measurement device is selected, the biological information of the subject is measured with body movement suppressed, thereby improving measurement accuracy. When the input device is not installed in the vicinity of the main body of the biological information measurement device, body movement may occur when the subject grips or operates the input device. When a measurement sequence corresponding to information indicating that the input device is not installed in the vicinity of the main body of the biometric information measuring device is selected, it is possible to prevent the measurement from having to be repeated due to body movement, thereby improving the success rate of the measurement.

[0009] The status information includes information indicating whether the subject is holding the input device, and the biological information measurement unit selects the measurement sequence corresponding to information indicating the subject is holding the input device or information indicating the subject is not holding the input device, and measures the subject's biological information. A measurement sequence corresponding to information indicating the subject is holding the input device or information indicating the subject is not holding the input device is selected, and measurement of the subject's biological information is performed. When the subject is holding the input device, body movement may occur when the subject operates the input device. When a measurement sequence corresponding to information indicating the subject is holding the input device is selected, it is possible to prevent measurement from being repeated due to body movement, thereby improving the success rate of measurement. When the subject is not holding the input device, body movement caused by the subject operating the input device is suppressed. When a measurement sequence corresponding to information indicating the subject is not holding the input device is selected, measurement of the subject's biological information is performed with body movement suppressed, thereby improving measurement accuracy.

[0010] The biological information measuring unit selects at least one measurement item from a plurality of measurement items related to the biological information of the subject placed on the placement surface based on the state information, and measures the biological information of the subject. For example, when the state of the input device is such that body movement occurs, a measurement item that is less susceptible to the influence of body movement is selected, thereby improving the success rate of measurement. When a measurement item that is less susceptible to the effects of body movement is selected, other measurement items are not selected, thereby shortening the measurement time.

[0011] The status information includes information indicating whether the input device is installed on the main unit, and the number of measurement items selected when the status information includes information indicating that the input device is not installed on the main unit is smaller than the number of measurement items selected when the status information includes information indicating that the input device is installed on the main unit. When the status information includes information indicating that the input device is not installed on the main unit, the number of measurement items selected is smaller, and therefore the time from start to completion of measurement of the subject's biological information is shorter.

[0012] The status information includes information indicating whether the input device is installed in the vicinity of the main body, and the number of measurement items selected when the status information includes information indicating that the input device is not installed in the vicinity of the main body is smaller than the number of measurement items selected when the status information includes information indicating that the input device is installed in the vicinity of the main body. When the status information includes information indicating that the input device is not installed in the vicinity of the main body, the number of measurement items selected is smaller, and therefore the time from start to completion of measurement of the subject's biological information is shorter.

[0013] The status information includes information indicating whether the subject is holding the input device, and the number of measurement items selected when the status information includes information indicating that the subject is holding the input device is smaller than the number of measurement items selected when the status information includes information indicating that the subject is not holding the input device. When the status information includes information indicating that the subject is holding the input device, the number of measurement items selected is smaller, and therefore the time from start to completion of measurement of the subject's biological information is shorter.

[0014] The biometric information measuring device includes a body movement measurement unit that measures the body movement of the subject placed on the placement surface. The body movement measurement unit selects the measurement sequence corresponding to the status information and the measurement results of the body movement measurement unit to measure the biometric information of the subject placed on the placement surface. For example, even if the state of the input device is such that the subject's body movement occurs, the subject may not be moving. For example, even if the state of the input device is such that the subject's body movement does not occur, the subject may be moving. By having the body movement measurement unit measure the subject's body movement, the subject's condition can be more accurately captured, and the biometric information of the subject can be measured more accurately. Since the biometric information of the subject can be measured taking into account the state of the input device and the subject's body movement, the measurement accuracy of the biometric information is improved. Furthermore, even if the state of the input device changes during measurement, the biometric information measurement is more likely to be completed, leading to an improved measurement success rate.

[0015] The biological information measuring device includes a body movement measuring unit that measures the body movement of the subject placed on the placement surface, and the biological information measuring unit selects at least one measurement item from the plurality of measurement items related to the subject's living body based on the status information and the measurement results of the body movement measuring unit to measure the biological information of the subject placed on the placement surface. For example, if the state of the input device is not conducive to the occurrence of body movement but the subject is moving, selecting a measurement item that is less affected by body movement improves the measurement success rate. If a measurement item that is less affected by body movement is selected, other measurement items are not selected, thereby shortening the measurement time.

[0016] The present invention also provides a biological information measurement method in which a computer executes at least a part of the above-mentioned processing, a biological information measurement method including at least a part of the above-mentioned processing, and a method for executing at least a part of the above-mentioned processing by a computer. The present invention can be understood as a program for causing a computer to execute the program, or as a computer-readable recording medium on which such a program is non-temporarily recorded. The above configurations and processes can be combined with each other to constitute the present invention as long as no technical contradiction occurs. [Effects of the Invention]

The current-applying electrode 5 and the voltage-measuring electrode 7 are arranged on the surface of the main body 2 so that when the person being measured, such as a user, stands on the surface of the main body 2, the tip end (toe side) of the sole of the right foot comes into contact with the current-applying electrode 5 and the rear end (heel side) of the sole of the right foot comes into contact with the voltage-measuring electrode 7. The person being measured stands on the surface of the biological information measuring device 1 so that the tip and rear ends of the sole of the left foot come into contact with the current-applying electrode 4 and the voltage-measuring electrode 6, respectively, and the tip and rear ends of the sole of the right foot come into contact with the current-applying electrode 5 and the voltage-measuring electrode 7, respectively. The current applying electrode 4 and the voltage measuring electrode 6 may be reversed in position, and the current applying electrode 5 and the voltage measuring electrode 7 may be reversed in position.

[0022] The display unit 3 is provided on the bottom surface of a recess 8 formed on the surface of the main body 2. The recess 8 is formed in the center of the surface of the main body 2. The recess 8 is a storage portion (ho The display unit 3 is, for example, a liquid crystal display panel such as an LCD (Liquid Crystal Display) or an EL (Electroluminescence) display. The main body 2 displays the results and various information and data. An input device operated by the subject can be installed on the main body 2 by accommodating the input device in the recess 8 of the main body 2. The input device is an operation unit that accepts operations from the subject and inputs information and data into the biological information measuring device 1. The input device may be a dedicated device attached to the biological information measuring device 1, or may be an information processing terminal owned by the subject. The information processing terminal may be, for example, a mobile terminal, a smartphone, a tablet terminal, etc.

[0023] FIG. 2 is a configuration diagram of the input device 100. The input device 100 shown in FIG. 2 is a dedicated device attached to the biological information measuring device 1. The input device 100 shown in FIG. 2 has switches 110 to 113. The switch 110 is a switch that accepts input of an instruction to turn on or off the power of the biological information measuring device 1 and an instruction to start and end measurement. The switch 111 is a switch that accepts an instruction to display various data stored in the biological information measuring device 1 on the display unit 3.

[0024] FIG. 3 is a schematic diagram of the biological information measuring device 1. In FIG. 3, the input device 100 is installed on the main body 2 by being accommodated in the recess 8 of the main body 2. In FIG. 3, the input device 100 is installed parallel to the main body 2 and laid flat on the main body 2. By accommodating the input device 100 in the recess 8 of the main body 2, the display unit 3 is covered by the input device 100. When the input device 100 is installed on the main body 2, the biological information measuring device 1 may switch to an audio mode in which information is conveyed to the subject by audio. When the input device 100 is installed on the main body 2, calibration for weight measurement is performed, and the weight of the input device 100 is excluded from the weight measurement of the subject. The biological information measuring device 1 shown in FIG. 3 is configured so that the display unit 3 is hidden when the input device 100 is installed on the main body 2. A subject standing on the surface of the main body 2 cannot see the display unit 3. Therefore, while the measurement of the subject's biological information is being performed, the subject is prevented from looking at the display unit 3, for example by moving their head, and the subject's body movement can be suppressed. This improves the measurement accuracy of the subject's biological information. While FIG. 3 shows an example configuration in which the input device 100 is housed in the recess 8 of the main body 2, the present invention is not limited to this example configuration. A rim shape (frame shape) may be provided on the top surface of the main body 2, and the input device 100 may be placed inside the frame shape. In other words, a convex rib shape that guides the periphery of the input device 100 may be provided on the top surface of the main body 2 as a housing for the input device 100.

The biological information measuring device 1 shown in FIG. 4 includes a main body 2, a display 3, current application electrodes 4 and 5, and voltage measurement electrodes 6 and 7. The display 3 is provided on the surface of the main body 2. The display 3 is disposed between the current application electrodes 4 and 5. A recess 9 is formed in the center of the surface of the main body 2. The recess 9 is a housing (holder) recessed from the surface of the main body 2. In FIG. 4, the input device 100 is installed on the main body 2 by partially housing the input device 100 in the recess 9 of the main body 2. When the input device 100 is installed on the main body 2, the biological information measuring device 1 may switch to an audio mode in which information is conveyed to the subject by audio. When the input device 100 is installed on the main body 2, calibration for weight measurement is performed, and the weight of the input device 100 is excluded from the measurement of the subject's weight. In Fig. 4, the input device 100 is installed perpendicular to the main body 2, and the input device 100 is placed upright on the main body 2. Fig. 5 is a side view of the biological information measuring device 1 as seen from the direction of arrow A1 in Fig. 4. A plurality of legs 10 are provided on the back surface of the main body 2.

[0026] FIG. 6 is a schematic diagram of a biological information measuring device 1. The biological information measuring device 1 shown in FIG. 6 may be employed. The biological information measuring device 1 shown in FIG. 6 includes a main body 2, a display 3, current application electrodes 4 and 5, and voltage measurement electrodes 6 and 7. The display 3 is provided on the surface of the main body 2. The display 3 is disposed between the current application electrodes 4 and 5. The biological information measuring device 1 shown in FIG. 6 includes a detachable housing (holder) 11 attached to the main body 2. The housing 11 can be attached to any position on the main body 2. In FIG. 6, the input device 100 is installed on the main body 2 by partially housing the input device 100 in the housing 11. When the input device 100 is installed on the main body 2, the biological information measuring device 1 may switch to an audio mode in which information is transmitted to the subject by audio. When the input device 100 is installed on the main body 2, calibration for weight measurement is performed, and the weight of the input device 100 is excluded from the measurement of the subject's weight. Fig. 7 is a side view of the biological information measuring device 1 as seen from the direction of arrow A2 in Fig. 6. A plurality of legs 10 are provided on the rear surface of the main body 2.

[0027] FIG. 8 is a schematic diagram of a biological information measurement device 1. The biological information measurement device 1 shown in FIG. 8 may be employed. The biological information measurement device 1 shown in FIG. 8 includes a main body 2, a display 3, current application electrodes 4 and 5, and voltage measurement electrodes 6 and 7. The biological information measurement device 1 shown in FIG. 8 includes a support (stand) 12 that is detachable from the main body 2. The support 12 can be attached to any position on the main body 2. In FIG. 8, the input device 100 is installed on the main body 2 by being supported by the support 12. When the input device 100 is installed on the main body 2, the biological information measurement device 1 may switch to an audio mode in which information is conveyed to the subject by audio. When the input device 100 is installed on the main body 2, calibration for weight measurement is performed, and the weight of the input device 100 is excluded from the weight measurement of the subject. FIG. 9 is a side view of the biological information measurement device 1 as viewed from the direction of arrow A3 in FIG. 8. A plurality of legs 10 are provided on the rear surface of the main body 2.

[0028] In the biological information measuring device 1 shown in FIGS. 4, 6, and 8, when the input device 100 is installed on the main body 2, the display 3 is turned off and no information or data is displayed on the display 3. When measurement of the subject's biological information is completed, information or data is displayed on the display 3. Therefore, while measurement of the subject's biological information is being performed, the display 3 does not display information or data. This prevents the subject from looking at the display 3, for example, by moving their head, thereby reducing the subject's body movement. A subject standing on the surface of the main body 2 cannot see the front or back of the input device 100 installed on the main body 2. Therefore, while measurement of the subject's biological information is being performed, the subject is prevented from looking at the input device 100, for example, by moving their head, thereby reducing the subject's body movement. This improves the measurement accuracy of the subject's biological information.

[0029] 10 is a block diagram showing the configuration of a biological information measuring device 1 according to an embodiment. The biological information measuring device 1 includes a display unit 3, a control unit 20, an electrode unit 21, an impedance measuring unit 22, a first sensor unit 23, a second sensor unit 24, a third sensor unit 25, a temperature measuring unit 26, a communication unit 27, and a storage unit 28.

Note that the configuration of the control unit 20 is not limited to these. For example, all of the functions of the control unit 20 may be realized by A part or part of the control unit 20 may be configured with a circuit such as an ASIC or FPGA, or all or part of the functions of the control unit 20 may be executed by a cloud server or other device.

[0031] The electrode unit 21 includes current application electrodes 4 and 5 for applying a constant current to the body of the subject to measure the bioimpedance of the subject, and voltage measurement electrodes 6 and 7 for measuring the voltage when the current is applied. The electrode unit 21 may include other electrodes different from the current application electrodes 4 and 5 and the voltage measurement electrodes 6 and 7.

[0032] The impedance measuring unit 22 measures the bioimpedance of the person being measured based on the values ​​of the current applied to the person's body from the current applying electrodes 4, 5 and the voltage measured by the voltage measuring electrodes 6, 7. The impedance measuring unit 22 outputs the bioimpedance of the person being measured to the control unit 20. The impedance measuring unit 22 may output the bioimpedance of the person being measured as an impedance pulse wave.

[0033] The first sensor unit 23 has a photoelectric sensor. The photoelectric sensor has an LED (Light Emitting Diode) that is a light-emitting unit that emits light, and a photodiode that is a light-receiving unit that receives light.

The second sensor unit 24 outputs a measurement value measured by the plurality of load cells to the control unit 20. A cushioning material such as a sponge may be provided inside the main body unit 2. This prevents the measurement values ​​measured by the plurality of load cells from being affected when the input device 100 vibrates.

Acceleration sensor 35 is arranged in the center of the rear side of main body 2.

[0036] The third sensor unit 25 has a sound collecting microphone. The third sensor unit 25 outputs the measurement value measured by the sound collecting microphone to the control unit 20. The temperature measurement unit 26 measures the temperature of the soles of the feet of the person being measured who is standing on the surface of the main unit 2. The temperature measurement unit 26 has a temperature sensor. The temperature sensor is arranged on the surface of the main unit 2. The temperature sensor may be arranged near the current application electrodes 4, 5, or may be arranged near the voltage measurement electrodes 6, 7. The communication unit 27 is an interface for wired or wireless communication. The communication unit 27 communicates with the input device 100.

[0037] The memory unit 28 stores information and data. The memory unit 28 may have at least one of a memory such as RAM and a storage. The storage may be a non-volatile storage device such as a ROM or a flash memory. The memory unit 28 stores various information such as the subject's personal data and the measurement results of the biological information measuring device 1. The personal data is used when calculating the subject's body composition. The personal data includes at least the subject's height and weight, and may further include the subject's age, gender, and other information. The subject's weight is measured when the subject stands on the surface of the main unit 2. The subject operates the input device 100 to input the subject's height, age, gender, and other information into the biological information measuring device 1, and the input data is stored in the memory unit 2. 8. In addition, when the height, age, sex, and other information of the person being measured are registered in the input device 100, the control unit 20 may obtain the height, age, sex, and other information of the person being measured from the input device 100 and store the information in the storage unit 28.

[0039] The state information acquisition unit 41 acquires information (state information) relating to the state of the input device 100. The body movement measurement unit 42 measures the body movement of the person being measured standing on the surface of the biological information measurement device 1, based on measurement values ​​output from at least one of the first sensor unit 23, the second sensor unit 24, and the electrode unit 21. The weight measurement unit 51 measures the weight of the person being measured standing on the surface of the biological information measurement device 1, based on measurement values ​​output from the second sensor unit 24.

[0040] The body composition measurement unit 52 measures the body composition of the subject standing on the surface of the biological information measurement device 1 based on the subject's personal data, the bioimpedance output from the impedance measurement unit 22, and the subject's weight according to a predetermined algorithm. Body composition is an index that indicates the proportion or amount of components that make up the body. Examples of body composition include, but are not limited to, body fat percentage, visceral fat level, skeletal muscle percentage, basal metabolic rate, body age, BMI, muscle percentage, muscle mass, body fat mass, bone mass, and water content. The subject's personal data includes previously measured weight and bioimpedance. The body composition measurement unit 52 may identify the subject by comparing previously measured weight and bioimpedance with the currently measured weight and bioimpedance. The body composition measurement unit 52 obtains the identified subject's personal data from the storage unit 28.

[0041] The standing balance measurement unit 53 measures the balance (standing balance) of the subject when standing on the surface of the biological information measurement device 1, based on the measurement value output from the second sensor unit 24. The standing balance measurement unit 53 may measure the standing balance of the subject by calculating the position of the center of gravity of the subject when standing. The standing balance measurement unit 53 may measure the standing balance of the subject according to a predetermined algorithm.

[0042] The cardiovascular measurement unit 54 measures the cardiovascular condition of the person being measured who is standing on the surface of the biological information measurement device 1 based on the measurement values ​​output from the second sensor unit 24 and the bioimpedance output from the impedance measurement unit 22 in accordance with a predetermined algorithm. The cardiovascular measurement unit 54 measures a BCG (ballistocardiogram), which is the vibration of blood pumped from the heart, based on the measurement values ​​output from the second sensor unit 24. The cardiovascular measurement unit 54 measures a leg IPG (impedance pulse wave) and a foot IPG (impedance pulse wave) based on the bioimpedance output from the impedance measurement unit 22. The leg IPG is an index indicating changes in the amount of blood in the blood vessels of the legs. The foot IPG is an index indicating changes in the amount of blood in the blood vessels of the feet. The cardiovascular measurement unit 54 creates an average waveform of the foot IPG (foot IPG waveform) based on the leg IPG. The cardiovascular measurement unit 54 calculates a pulse wave transit time (PTT) from the BCG waveform and characteristic points of the foot IPG waveform.

[0043] FIG. 14 is a diagram illustrating the relationship between the BCG waveform, the foot IPG waveform, and the PTT. As shown in FIG. 14, it is possible to calculate the PTT (pulse wave transit time) by taking the difference (time) between the reference point of the BCG waveform and the characteristic point of the foot IPG waveform. The cardiovascular measurement unit 54 calculates the PWV (pulse wave velocity) by dividing the measurement section distance by the PTT. The harder the blood vessels are, the larger the PWV value becomes, so the PWV is used as an index representing the hardness of the blood vessels. The cardiovascular measurement unit 54 calculates the PWV (pulse wave velocity) based on a predetermined algorithm. The measured values ​​are converted into indices (cardiovascular indices) that represent organ function and blood vessel conditions, and the cardiovascular indices are calculated. To measure the cardiovascular condition of the person being measured, the person needs to maintain a state of no body movement or minimal body movement for about 20 to 30 seconds. Therefore, the cardiovascular measurement unit 54 starts measuring the cardiovascular condition of the person being measured when the person is in a state of no body movement or minimal body movement.

[0044] The operation of the biological information measuring device 1 will be described with reference to Fig. 15. Fig. 15 is a flowchart for explaining the operation of the biological information measuring device 1. For example, the control unit 20 reads out a program stored in the storage unit 28, thereby executing each process in the flowchart of Fig. 15.

[0045] In step S101, the person being measured presses the switch 110 of the input device 100 to turn on the power of the biological information measuring device 1. Alternatively, in step S101, the person being measured may stand on the surface of the main body 2 to turn on the power of the biological information measuring device 1.

[0046] In step S102, the state information acquisition unit 41 acquires state information of the input device 100. The state information of the input device 100 will be described. The state information of the input device 100 may include information indicating whether the input device 100 is installed on the main body 2.

[0047] The process of determining whether or not the input device 100 is installed on the main body 2 will be described. The input device 100 may have a display unit such as a liquid crystal display panel or an EL display, and may output light of a predetermined amplitude or frequency. The state information acquisition unit 41 communicates with the input device 100 via the communication unit 27 and causes the screen of the display unit of the input device 100 to emit light. The state information acquisition unit 41 may determine whether or not the input device 100 is installed on the main body 2 based on a measurement value output from the first sensor unit 23. The photoelectric sensor of the first sensor unit 23 may be disposed near the installation location of the input device 100. If the state information acquisition unit 41 detects light of a predetermined amplitude or frequency, it determines that the input device 100 is installed on the main body 2. In this case, the state information of the input device 100 includes information indicating that the input device 100 is installed on the main body 2. If the state information acquisition unit 41 does not detect light of a predetermined amplitude or frequency, it determines that the input device 100 is not installed on the main body 2. In this case, the state information of the input device 100 includes information indicating that the input device 100 is not installed in the main body part 2.

[0048] The input device 100 may have a vibrator formed by a small motor or the like, and may generate vibrations in a predetermined pattern. The state information acquisition unit 41 communicates with the input device 100 via the communication unit 27 and vibrates the input device 100. The state information acquisition unit 41 may determine whether the input device 100 is installed on the main body unit 2 based on the measurement value output from the second sensor unit 24. When the state information acquisition unit 41 detects vibration of the input device 100, it determines that the input device 100 is installed on the main body unit 2. When the state information acquisition unit 41 does not detect vibration of the input device 100, it determines that the input device 100 is not installed on the main body unit 2.

[0049] The input device 100 may have an audio output device, and may output a sound (audible or inaudible sound) having a predetermined amplitude or more. The state information acquisition unit 41 communicates with the input device 100 via the communication unit 27, and causes the input device 100 to output a sound having a predetermined amplitude or more. The state information acquisition unit 41 may determine whether or not the input device 100 is installed in the main body unit 2 based on the measurement value output from the third sensor unit 25. When the state information acquisition unit 41 detects a sound having a predetermined amplitude or more, it determines that the input device 100 is installed in the main body unit 2. When the state information acquisition unit 41 does not detect a sound having a predetermined amplitude or more, it determines that the input device 100 is not installed in the main body unit 2. It is determined that the

[0050] The input device 100 may have an angular velocity sensor such as a gyro sensor. The state information acquisition unit 41 may communicate with the input device 100 via the communication unit 27 and acquire angle information (measurement value of the angular velocity sensor) of the input device 100. The state information acquisition unit 41 may determine whether or not the input device 100 is installed on the main body 2 based on the measurement value of the angular velocity sensor of the input device 100. If the measurement value of the angular velocity sensor of the input device 100 is within a predetermined range, the state information acquisition unit 41 determines that the input device 100 is installed on the main body 2. If the measurement value of the angular velocity sensor of the input device 100 is not within the predetermined range, the state information acquisition unit 41 determines that the input device 100 is not installed on the main body 2. For example, in the case of FIG. 3 , the measurement value of the angular velocity sensor of the input device 100 is within the predetermined range.

[0051] The state information acquiring unit 41 may perform RFID communication with the input device 100 via the communication unit 27, and determine whether or not an RFID signal can be acquired from the input device 100. When the state information acquiring unit 41 acquires an RFID signal from the input device 100, it determines that the input device 100 is installed in the main body 2. When the state information acquiring unit 41 does not acquire an RFID signal from the input device 100, it determines that the input device 100 is not installed in the main body 2.

[0052] Capacitive detection sensors may be disposed in the recesses 8 and 9, the housing 11, and the support 12. The state information acquisition unit 41 may determine whether or not the input device 100 is installed on the main body 2 based on a measurement value (capacitance) of the capacitive detection sensor. If the capacitance changes, the state information acquisition unit 41 determines that the input device 100 is installed on the main body 2. If the capacitance does not change, the state information acquisition unit 41 determines that the input device 100 is not installed on the main body 2.

[0053] The state information of the input device 100 may include information indicating whether or not the input device 100 is installed in the vicinity of the main body 2. A process for determining whether or not the input device 100 is installed in the vicinity of the main body 2 will be described. The vicinity of the main body 2 is, for example, a sink, a shelf, etc., but is not limited to these.

[0054] The input device 100 may have an acceleration sensor. The state information acquisition unit 41 may communicate with the input device 100 via the communication unit 27 and acquire acceleration information (measured values ​​of the acceleration sensor) of the input device 100. The state information acquisition unit 41 may determine whether the input device 100 is installed in the vicinity of the main body 2 based on the measured values ​​of the acceleration sensor of the input device 100. If the measured values ​​of the acceleration sensor of the input device 100 are less than a threshold value for a predetermined period of time, the state information acquisition unit 41 determines that the input device 100 is installed in the vicinity of the main body 2. In this case, the state information of the input device 100 includes information indicating that the input device 100 is installed in the vicinity of the main body 2. If the input device 100 is installed in the vicinity of the main body 2, the input device 100 is not moving and maintains a stable state, and therefore the measured values ​​of the acceleration sensor of the input device 100 are less than the threshold value for a predetermined period of time. When the measurement value of the acceleration sensor of the input device 100 continues to be equal to or greater than the threshold value for a predetermined time, the state information acquiring unit 41 determines that the input device 100 is not installed in the vicinity of the main body unit 2. In this case, the state information of the input device 100 includes information indicating that the input device 100 is not installed in the vicinity of the main body unit 2. When the subject is wearing the input device 100, the input device 100 is moving and is not maintaining a stable state, so the measurement value of the acceleration sensor of the input device 100 continues to be equal to or greater than the threshold value for a predetermined time.

[0055] The input device 100 may have a proximity sensor. The state information acquisition unit 41 may communicate with the input device 100 via the communication unit 27 and acquire a measurement value of the proximity sensor of the input device 100. The state information acquisition unit 41 may acquire a measurement value of the proximity sensor of the input device 100 based on the measurement value of the proximity sensor of the input device 100. Alternatively, the state information acquisition unit 41 may determine whether the input device 100 is installed in the vicinity of the main body 2. If the measurement value of the proximity sensor of the input device 100 is less than the threshold, the state information acquisition unit 41 determines that the input device 100 is installed in the vicinity of the main body 2. For example, if the input device 100 is installed on a shelf, the distance between the input device 100 and the shelf is short, so the measurement value of the proximity sensor of the input device 100 is less than the threshold. If the measurement value of the proximity sensor of the input device 100 is equal to or greater than the threshold, the state information acquisition unit 41 determines that the input device 100 is not installed in the vicinity of the main body 2. If the input device 100 is not installed in the vicinity of the main body 2, the distance between the input device 100 and an object is long, so the measurement value of the proximity sensor of the input device 100 is equal to or greater than the threshold.

[0056] The state information of the input device 100 may include information indicating whether the person being measured is holding the input device 100. A process for determining whether the input device 100 is being held by the person being measured will be described. The state information acquisition unit 41 may communicate with the input device 100 via the communication unit 27 and acquire acceleration information (measured value of an acceleration sensor) of the input device 100. The state information acquisition unit 41 may determine whether the input device 100 is being held by the person being measured based on the measured value of the acceleration sensor of the input device 100. If the measured value of the acceleration sensor of the input device 100 is equal to or greater than a threshold, the state information acquisition unit 41 determines that the input device 100 is being held by the person being measured. In this case, the state information of the input device 100 includes information indicating that the person being measured is holding the input device 100. If the person being measured is holding the input device 100, the input device 100 is moving, and the measured value of the acceleration sensor of the input device 100 is equal to or greater than a threshold. If the measurement value of the acceleration sensor of the input device 100 is less than the threshold value, the state information acquiring unit 41 determines that the input device 100 is not being held by the person being measured. In this case, the state information of the input device 100 includes information indicating that the person being measured is not holding the input device 100. When the person being measured is not holding the input device 100, the input device 100 is not moving, and therefore the measurement value of the acceleration sensor of the input device 100 is less than the threshold value.

[0057] In step S103, the biological information measurement unit 43 selects a measurement sequence corresponding to the status information of the input device 100 and measures the biological information of the subject standing on the surface of the main body unit 2. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one measurement item from a plurality of measurement items related to the body of the subject standing on the surface of the main body unit 2 based on the status information of the input device 100. The plurality of measurement items related to the body of the subject may include a measurement item for measuring weight, a measurement item for measuring body composition, a measurement item for measuring standing balance, and a measurement item for measuring cardiovascular status.

[0058] The biological information measurement unit 43 selects a measurement sequence corresponding to information indicating that the input device 100 is installed on the main body 2 or information indicating that the input device 100 is not installed on the main body 2, and measures the biological information of the subject standing on the surface of the main body 2. This allows the biological information of the subject to be measured while taking into account the state of the input device 100, which is a factor in generating body movement. When the state information of the input device 100 includes information indicating that the input device 100 is installed on the main body 2, the biological information measurement unit 43 may select a measurement sequence for measuring body weight, body composition, standing balance, and cardiovascular status to measure the biological information of the subject. Installing the input device 100 on the main body 2 suppresses body movement caused by the subject holding the input device 100. When a measurement sequence corresponding to information indicating that the input device 100 is installed on the main body 2 is selected, the biological information of the subject is measured while body movement is suppressed, thereby improving measurement accuracy. The biological information measurement unit 43 may measure the biological information of the subject by selecting measurement items for measuring weight, body composition, standing balance, and cardiovascular condition from among a plurality of measurement items related to the subject's biological body. When the input device 100 is installed in the main body 2, the subject is considered to have the intention to measure weight, body composition, standing balance, and cardiovascular condition, and the biological information of the subject is measured. Furthermore, when the status information of the input device 100 includes information indicating that the input device 100 is installed in the main body 2, the biological information measurement unit 43 may select measurement items for measuring weight, body composition, standing balance, and cardiovascular condition from among a plurality of measurement items related to the subject's biological body. Alternatively, all of the measurement items may be selected to measure the biological information of the subject.

[0059] If the status information of the input device 100 includes information indicating that the input device 100 is not installed on the main unit 2, the biological information measurement unit 43 may select at least one of a measurement sequence for measuring weight and a measurement sequence for measuring body composition to measure the biological information of the subject. Measurement of the subject's weight and body composition is not affected by the subject's body movement. If the input device 100 is not installed on the main unit 2, body movement may occur when the subject grips or operates the input device 100. If a measurement sequence corresponding to information indicating that the input device 100 is not installed on the main unit 2 is selected, retrying the measurement due to body movement can be prevented, thereby improving the success rate of the measurement. The biological information measurement unit 43 may select at least one of a measurement item for measuring weight and a measurement item for measuring body composition from among multiple measurement items related to the subject's body to measure the biological information of the subject. For example, if the state of the input device 100 is such that body movement may occur, selecting measurement items that are less affected by body movement improves the success rate of the measurement. When a measurement item that is less susceptible to the influence of body movement is selected, other measurement items are not selected, thereby shortening the measurement time. The number of measurement items selected when the status information of the input device 100 includes information indicating that the input device 100 is not installed in the main body 2 is fewer than the number of measurement items selected when the status information of the input device 100 includes information indicating that the input device 100 is installed in the main body 2. At least one of the weight and body composition of the person being measured is measured, and measurement of other measurement items is not performed, thereby shortening the time from the start to the completion of measurement of the person's biological information.

[0060] The biological information measurement unit 43 selects a measurement sequence corresponding to information indicating that the input device 100 is installed near the main body 2 or information indicating that the input device 100 is not installed near the main body 2, and measures the biological information of the subject standing on the surface of the main body 2. This allows the biological information of the subject to be measured while taking into account the state of the input device 100, which is a cause of body movement. When the state information of the input device 100 includes information indicating that the input device 100 is installed near the main body 2, the biological information measurement unit 43 may select a measurement sequence for measuring body weight, body composition, standing balance, and cardiovascular status to measure the biological information of the subject. By installing the input device 100 near the main body 2, body movement caused by the subject holding the input device 100 is suppressed. When a measurement sequence corresponding to information indicating that the input device 100 is installed on the main body 2 is selected, the biological information of the subject is measured while body movement is suppressed, thereby improving measurement accuracy. The biological information measurement unit 43 may measure the biological information of the subject by selecting measurement items for measuring weight, body composition, standing balance, and cardiovascular status from among multiple measurement items related to the subject's biological status. If the input device 100 is installed in the vicinity of the main body 2, the subject is considered to have an intention to have their weight, body composition, standing balance, and cardiovascular status measured, and the biological information of the subject is measured. Furthermore, if the status information of the input device 100 includes information indicating that the input device 100 is installed in the vicinity of the main body 2, the biological information measurement unit 43 may select all measurement items from among multiple measurement items related to the subject's biological status to measure the biological information of the subject.

[0061] If the status information of the input device 100 includes information indicating that the input device 100 is not installed in the vicinity of the main body 2, the biological information measurement unit 43 may select at least one of a measurement sequence for measuring weight and a measurement sequence for measuring body composition to measure the biological information of the subject. Measurement of the subject's weight and body composition is not affected by the subject's body movements. If the input device 100 is not installed in the vicinity of the main body 2, body movements may occur when the subject grips the input device 100 or operates the input device 100. If a measurement sequence corresponding to information indicating that the input device 100 is not installed in the vicinity of the main body 2 is selected, the measurement sequence is selected to prevent re-measurement due to body movements. This improves the success rate of measurement. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one of a measurement item for measuring weight and a measurement item for measuring body composition from among multiple measurement items related to the subject's biological information. For example, when the state of the input device 100 is such that body movement may occur, the measurement success rate is improved by selecting a measurement item that is less affected by body movement. When a measurement item that is less affected by body movement is selected, other measurement items are not selected, thereby shortening the measurement time. The number of measurement items selected when the status information of the input device 100 includes information indicating that the input device 100 is not installed near the main unit 2 is fewer than the number of measurement items selected when the status information of the input device 100 includes information indicating that the input device 100 is installed near the main unit 2. Because at least one of the subject's weight and body composition is measured and the other measurement items are not measured, the time from start to completion of measurement of the subject's biological information is shortened.

[0062] The biological information measurement unit 43 selects a measurement sequence corresponding to information indicating that the subject is holding the input device 100 or information indicating that the subject is not holding the input device 100, and measures the biological information of the subject standing on the surface of the main unit 2. This allows the biological information of the subject to be measured taking into account the state of the input device 100, which is a factor in generating body movement. If the state information of the input device 100 includes information indicating that the subject is not holding the input device 100, the biological information measurement unit 43 may select a measurement sequence for measuring body weight, body composition, standing balance, and cardiovascular status to measure the biological information of the subject. The biological information measurement unit 43 may select measurement items for measuring body weight, body composition, standing balance, and cardiovascular status from among multiple measurement items related to the subject's body, and measure the biological information of the subject. If the subject is not holding the input device 100, the subject is considered to have the intention to measure their body weight, body composition, standing balance, and cardiovascular status, and the biological information of the subject is measured. In addition, if the status information of the input device 100 includes information indicating that the subject is not holding the input device 100, the biometric information measurement unit 43 may select all of the multiple measurement items related to the subject's biological information and measure the subject's biometric information.

[0063] When the status information of the input device 100 includes information indicating that the subject is holding the input device 100, the biological information measurement unit 43 may select at least one of a measurement sequence for measuring weight and a measurement sequence for measuring body composition to measure the subject's biological information. Measurement of the subject's weight and body composition is not affected by the subject's body movement. When the subject is holding the input device 100, the subject's operation of the input device 100 may cause body movement. When a measurement sequence corresponding to the information indicating that the subject is holding the input device 100 is selected, it is possible to prevent the measurement from having to be repeated due to body movement, thereby improving the success rate of the measurement. The biological information measurement unit 43 may measure the subject's biological information by selecting at least one of a measurement item for measuring weight and a measurement item for measuring body composition from among multiple measurement items related to the subject's body. For example, when the state of the input device 100 is such that body movement may occur, selecting a measurement item that is less affected by body movement improves the success rate of the measurement. When a measurement item that is less susceptible to the influence of body movement is selected, other measurement items are not selected, thereby shortening the measurement time. The number of measurement items selected when the status information of the input device 100 includes information indicating that the subject is holding the input device 100 is fewer than the number of measurement items selected when the status information of the input device 100 includes information indicating that the subject is not holding the input device 100. At least one of the subject's weight and body composition is measured, and measurement of other measurement items is not performed, thereby shortening the time from start to completion of measurement of the subject's biological information.

[0064] In step S102, the body movement measuring unit 42 measures the first sensor unit 23 and the second sensor unit 24. and electrode unit 21, and may measure the body movement of the person being measured standing on the surface of main unit 2 and determine whether the body movement of the person being measured is large. That is, body movement measurement unit 42 may measure the body movement of the person being measured standing on the surface of biological information measurement device 1 and determine whether the person being measured continues to be stationary. A stationary state is a state in which the measurement values ​​output from first sensor unit 23, second sensor unit 24, or electrode unit 21 do not fluctuate by more than a predetermined value. The measurement values ​​output from load cells 31 to 34 may be affected by vibrations of input device 100. Therefore, body movement measurement unit 42 may measure the body movement of the person being measured standing on the surface of main unit 2 based on the measurement values ​​output from acceleration sensor 35, without using the measurement values ​​output from load cells 31 to 34.

[0065] The process of determining whether the subject's body movement is large will be described. When the subject's feet move while standing on the surface of the main body 2, the measurement value output from the first sensor 23 fluctuates. The measurement value output from the first sensor 23 is, for example, a voltage value or the amount of light received by a photodiode. If the measurement value output from the first sensor 23 fluctuates continuously for a predetermined time, the body movement measurement unit 42 determines that the subject's body movement is large. If the measurement value output from the first sensor 23 fluctuates continuously for a predetermined time, the body movement measurement unit 42 may determine that the subject is not staying still. The body movement measurement unit 42 outputs a measurement result including a result indicating that the subject is not staying still (a result indicating that the subject's body movement is large). If the measurement value output from the first sensor 23 does not fluctuate continuously for a predetermined time, the body movement measurement unit 42 determines that the subject's body movement is small. If the measurement value output from the first sensor unit 23 does not fluctuate for a predetermined period of time, the body movement measurement unit 42 may determine that the subject is continuing to be stationary. The body movement measurement unit 42 outputs a measurement result including a result indicating that the subject is continuing to be stationary (a result indicating that the subject's body movement is small).

[0066] When the subject standing on the surface of the main body 2 performs a predetermined movement, the measurement value output from the second sensor unit 24 increases. For example, the predetermined movement may be, but is not limited to, the subject moving his or her head. If the measurement value output from the second sensor unit 24 is equal to or greater than the threshold value for a predetermined period of time, the body movement measurement unit 42 determines that the subject's body movement is large. If the average value of the measurement values ​​output from the second sensor unit 24 within the predetermined period of time is equal to or greater than the threshold value, the body movement measurement unit 42 determines that the subject's body movement is large. In these cases, the body movement measurement unit 42 may determine that the subject is not remaining still. The body movement measurement unit 42 outputs a measurement result including a result indicating that the subject is not remaining still (a result indicating that the subject's body movement is large). If the measurement value output from the second sensor unit 24 is equal to or less than the threshold value for a predetermined period of time, the body movement measurement unit 42 determines that the subject's body movement is small. If the average value of the measurement values ​​output from the second sensor unit 24 within a predetermined time is less than the threshold value, the body movement measurement unit 42 determines that the body movement of the person being measured is small. In these cases, the body movement measurement unit 42 may determine that the person being measured is continuing to be stationary. The body movement measurement unit 42 outputs a measurement result including a result indicating that the person being measured is continuing to be stationary (a result indicating that the person being measured has small body movement). The threshold value used to measure the person being measured may be determined by experiment or simulation. For example, when the person being measured looks at the display unit 3, the threshold value may be determined based on the measurement values ​​output from the second sensor unit 24.

[0067] When the feet of the person being measured, which are placed on the surface of the main body 2, move, the measurement value output from the electrode unit 21 fluctuates. The measurement value output from the electrode unit 21 is, for example, a myoelectric potential. When the measurement value output from the electrode unit 21 fluctuates continuously for a predetermined time, the body movement measurement unit 42 determines that the body movement of the person being measured is large. When the measurement value output from the electrode unit 21 fluctuates continuously for a predetermined time, the body movement measurement unit 42 may determine that the person being measured is not continuing to stay still. The body movement measurement unit 42 outputs a measurement result including a result indicating that the person being measured is not continuing to stay still (a result indicating that the person being measured is moving greatly). When the measurement value output from the electrode unit 21 does not fluctuate continuously for a predetermined time, the body movement measurement unit 42 determines that the body movement of the person being measured is small. If the measurement value output from the electrode unit 21 does not fluctuate for a predetermined period of time, the body movement measurement unit 42 may determine that the person being measured is continuing to be stationary. The body movement measurement unit 42 outputs a measurement result including a result indicating that the person being measured is continuing to be stationary (a result indicating that the person being measured has little body movement).

[0068] In step S103, the biological information measurement unit 43 may select a measurement sequence corresponding to the state information of the input device 100 and the measurement results of the body movement measurement unit 42 to measure the biological information of the subject. For example, even if the state of the input device 100 is such that body movement of the subject occurs, the subject may not be moving. For example, even if the state of the input device 100 is such that body movement of the subject does not occur, the subject may be moving. By having the body movement measurement unit 42 measure the body movement of the subject, the subject's condition can be more accurately captured, and the biological information of the subject can be measured more accurately. The biological information measurement unit 43 may select at least one measurement item from among multiple measurement items related to the subject's body placed on the surface of the main unit 2 based on the state information of the input device 100 and the measurement results of the body movement measurement unit 42, and measure the biological information of the subject. For example, if the state of the input device 100 is such that it will not lead to body movement, but the subject is moving, the measurement success rate will be improved by selecting a measurement item that is less susceptible to the influence of body movement. When a measurement item that is less susceptible to the influence of body movement is selected, other measurement items will not be selected, thereby shortening the measurement time.

[0069] A case will be described in which the status information of the input device 100 includes information indicating that the input device 100 is installed on the main body 2, and the measurement result of the body movement measurement unit 42 includes a result indicating that the subject is continuing to remain motionless. The biological information measurement unit 43 may measure the subject's biological information by selecting a measurement sequence for measuring body weight, body composition, standing balance, and cardiovascular status. The biological information measurement unit 43 may measure the subject's biological information by selecting measurement items that measure body weight, body composition, standing balance, and cardiovascular status from among multiple measurement items related to the subject's body. Alternatively, the biological information measurement unit 43 may measure the subject's biological information by selecting all measurement items from among multiple measurement items related to the subject's body.

[0070] The following describes a case where the status information of the input device 100 includes information indicating that the input device 100 is not installed on the main body 2, or a case where the measurement result of the body movement measurement unit 42 includes a result indicating that the subject is not continuing to remain motionless. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one of a measurement sequence for measuring weight and a measurement sequence for measuring body composition. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one of a measurement item for measuring weight and a measurement item for measuring body composition from among multiple measurement items related to the subject's biology.

[0071] A case will be described in which the status information of the input device 100 includes information indicating that the input device 100 is installed near the main body 2, and the measurement result of the body movement measurement unit 42 includes a result indicating that the subject is continuing to remain motionless. The biological information measurement unit 43 may measure the subject's biological information by selecting a measurement sequence for measuring body weight, body composition, standing balance, and cardiovascular status. The biological information measurement unit 43 may measure the subject's biological information by selecting measurement items that measure body weight, body composition, standing balance, and cardiovascular status from among multiple measurement items related to the subject's body. Alternatively, the biological information measurement unit 43 may measure the subject's biological information by selecting all measurement items from among multiple measurement items related to the subject's body.

[0072] If the state information of the input device 100 includes information indicating that the input device 100 is not installed in the vicinity of the main body 2, or if the measurement result of the body movement measurement unit 42 indicates that the subject is still in a stationary state, The following describes a case where the result includes a result indicating that the subject is not continuing to use the device. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one of a measurement sequence for measuring weight and a measurement sequence for measuring body composition. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one of a measurement item for measuring weight and a measurement item for measuring body composition from among a plurality of measurement items related to the subject's biology.

[0073] A case will be described in which the status information of the input device 100 includes information indicating that the subject is not holding the input device 100, and the measurement result of the body movement measurement unit 42 includes a result indicating that the subject is continuing to remain motionless. The biological information measurement unit 43 may measure the subject's biological information by selecting a measurement sequence for measuring body weight, body composition, standing balance, and cardiovascular status. The biological information measurement unit 43 may measure the subject's biological information by selecting measurement items that measure body weight, body composition, standing balance, and cardiovascular status from among multiple measurement items related to the subject's body. Alternatively, the biological information measurement unit 43 may measure the subject's biological information by selecting all measurement items from among multiple measurement items related to the subject's body.

[0074] The following describes a case where the status information of the input device 100 includes information indicating that the subject is holding the input device 100, or a case where the measurement result of the body movement measurement unit 42 includes a result indicating that the subject is not continuing to remain motionless. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one of a measurement sequence for measuring weight and a measurement sequence for measuring body composition. The biological information measurement unit 43 may measure the biological information of the subject by selecting at least one of a measurement item for measuring weight and a measurement item for measuring body composition from among a plurality of measurement items related to the subject's biology.

[0075] A guide display prompting the user to install the input device 100 may be displayed on the display unit of the input device 100. The guide display may be a message prompting the user to install the input device 100 on the main body 2. The guide display may be a message prompting the user to install the input device 100 in the vicinity of the main body 2. Furthermore, the audio output device of the input device 100 may output a guide audio prompting the user to install the input device 100. The guide audio may be an audio prompting the user to install the input device 100 on the main body 2. The guide audio may be an audio prompting the user to install the input device 100 in the vicinity of the main body 2. The guide display processing and the guide audio processing may be performed before the user stands on the surface of the main body 2. The guide display processing and the guide audio processing may be performed when the user is holding the input device 100.

[0076] When the status information of the input device 100 includes information indicating that the subject is holding the input device 100, the status information acquiring unit 41 may communicate with the input device 100 via the communication unit 27 and issue a predetermined instruction to the input device 100. The input device 100 displays a guidance display on the display unit of the input device 100 based on the predetermined instruction. The guidance display may be displayed by an application of the input device 100. The guidance display may be a display that prompts the subject to place their finger on the screen of the display unit of the input device 100. The guidance display may be a display using a level application. The guidance display may be a display that indicates the remaining time until the measurement of the biological information is completed. When the subject places their finger on the screen of the display unit of the input device 100, the subject cannot operate the input device 100 while the measurement of the biological information is being performed. When the guidance display is displayed on the display unit of the input device 100, the subject will stare at the display unit of the input device 100. This inhibits the subject from looking at their feet, for example by moving their head, thereby inhibiting their body movement. This improves the accuracy of measuring the subject's biological information.

[0077] For example, if an information processing device is placed in the vicinity of a bathroom sink, the heart rate may be affected by body movement. A case will be described in which, while biometric information is being measured for all measurement items, including items related to the state of blood vessels, a voice or an alarm sound is output from the information processing terminal, which is an example of the input device 100, and the subject transitions to a state in which the subject is holding the information processing terminal. In this case, a message indicating that the measurement of biometric information has been interrupted is displayed on the display unit 3, and biometric information for measurement items for which measurement has been completed is stored in the memory unit 28. Biometric information for measurement items for which measurement has been completed may be displayed on the display unit 3. Measurement items for which measurement has not been completed may be displayed on the display unit 3. Measurement items for which measurement has been completed may be displayed on the display unit of the information processing terminal. Measurement items for which measurement has not been completed may be displayed on the display unit of the information processing terminal. For example, a message including whether remeasurement is necessary, recording of measurement data, the time remaining until measurement is completed, etc. may be displayed on the display unit 3 or on the display unit of the information processing terminal. Furthermore, if the subject's body movement occurs due to holding the information processing device, causing a prolonged measurement time for the biometric information, a message indicating that the measurement time has been prolonged may be displayed on the display unit 3. By having the subject recognize the cause of the prolonged measurement time, the subject's body movements are suppressed during the next measurement of biological information. In this way, even if the state of the input device 100 changes during measurement, the measurement sequence is changed and selected according to the state information of the input device 100, a body movement suppression notification is issued to the subject, or measurement items are switched to those less affected by body movements at an early stage. This makes it easier to complete the measurement, leading to an improved measurement success rate. Therefore, it is possible to achieve a measurement that is desirable for the subject.

[0078] When a sound is output from the information processing terminal and the subject holds the information processing terminal, the biological information measurement unit 43 excludes each piece of data recorded while the biological information is being measured. In this case, the biological information measurement unit 43 performs an extension process for the biological information measurement. When the subject holds the information processing terminal, the display unit 3 may display a message indicating that the biological information measurement has been extended. When the subject recognizes that the biological information measurement has been extended, the subject's body movements during the next biological information measurement are suppressed. Furthermore, for example, if a dedicated application is installed in the information processing terminal and the dedicated application is running, the information processing terminal may be configured not to output any sound while the biological information is being measured.

[0079] The biological information measuring device 1 may include an audio output device. If the input device 100 remains attached to the main body 2 even after a predetermined time has elapsed since the measurement of the biological information has been completed, the audio output device of the biological information measuring device 1 may output an alarm sound. This can prevent the input device 100 from being left attached to the main body 2.

[0080] When the measurement of the subject's biological information is being performed for all measurement items among multiple measurement items related to the subject's biological activity, the display unit 3 may be configured not to display information while the measurement process is being performed by the biological information measurement unit 43. The subject's behavior of looking at the information displayed on the display unit 3 (looking at their feet) affects the measurement of their cardiovascular condition. By having the display unit 3 not display information while the measurement process is being performed by the biological information measurement unit 43, the subject's body movement can be suppressed, improving the accuracy of measuring their cardiovascular condition.
