[0002] Conventionally, an acoustic device has been disclosed that includes a pair of biosensor units, one for the left and one for the right, that are inserted into the ears (see Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-55155 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the acoustic device disclosed in Patent Document 1, the amount of power used in pulse measurement (heart rate measurement) is greater than the amount of power used in body temperature measurement, so if the left and right sensor units are provided with independent batteries, the battery of the left sensor unit will run out faster than that of the right sensor unit, resulting in a difference in the remaining battery power of the left and right sensor units.This results in a problem of a limited time during which pulse measurement and body temperature measurement can be performed simultaneously.

[0005] The present invention has been made in view of the above circumstances, and has as its object to extend the time during which heart rate measurement and body temperature measurement can be performed simultaneously. [Means for solving the problem]

[Effects of the Invention]

[0007] According to the present invention, the time during which heart rate measurement and body temperature measurement can be performed simultaneously can be extended. [Brief explanation of the drawings]

[0009] An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a biological information measurement system 100 includes a biological information measurement device 1 and a terminal device 2. The biological information measurement device 1 and the terminal device 2 can transmit and receive data via wireless or wired communication. The biological information measurement device 1 is an earphone-type device worn on the left and right ears of a user (subject) and measures the user's deep body temperature (ear temperature) and heart rate over an extended period of time. The biological information measurement device 1 is, for example, a neckband-type device in which a first wearable device 12 (described later) worn on the user's left ear and a second wearable device 13 (described later) worn on the user's right ear are connected by a cable. The terminal device 2 is carried by the user and records deep body temperature data D1 and heart rate data D2 acquired from the biological information measurement device 1 in a storage unit 23 (see FIG. 3) and displays the data on a display unit 24 (see FIG. 3).

[0010] 2, the biological information measuring device 1 is configured to include a control unit 11, a first wearable device 12, a second wearable device 13, a storage unit 14, a communication unit 15, and a timing unit 16. The control unit 11 is a computer that controls each unit of the biological information measuring device 1. For example, the control unit 11 is configured to include at least one CPU (Central Processing Unit), RAM (Random Access Memory), etc., and reads out a specified program from among programs stored in the storage unit 14, expands it in the RAM, and executes various processes in cooperation with the expanded program.

[0011] The first wearable device 12 is a device worn on the user's left ear and includes a body temperature measurement unit 121, a heartbeat measurement unit 122, and a battery 123. The body temperature measurement unit 121 includes a chip-type temperature sensor IC (integrated circuit) that outputs a digital signal representing a detected temperature, a circuit that outputs the digital signal to the control unit 11, and the like. Note that the body temperature measurement unit 121 is not limited to this, and may include a temperature sensor IC that outputs an analog voltage signal whose magnitude corresponds to the detected temperature, or a temperature detection element (e.g., a thermistor) whose electrical characteristics change according to temperature. The heartbeat measurement unit 122 includes a sensor that detects the user's heartbeat, a circuit that counts the detected heartbeats, calculates the number of heartbeats per unit time (e.g., 60 seconds), and outputs the result of the calculation to the control unit 11. The heartbeat measurement unit 122 detects the heartbeat, for example, according to photoplethysmography. The battery 123 supplies power to the body temperature measurement unit 121 and the heartbeat measurement unit 122. In this embodiment, the battery 123 is a rechargeable battery.

[0012] The second wearable device 13 is a device worn on the user's right ear and includes a body temperature measurement unit 131, a heartbeat measurement unit 132, and a battery 133. Similar to the body temperature measurement unit 121 described above, the body temperature measurement unit 131 includes a chip-type temperature sensor IC (integrated circuit) that outputs a digital signal representing a detected temperature, a circuit that outputs the digital signal to the control unit 11, and the like. The body temperature measurement unit 131 is not limited to this, and may include a temperature sensor IC that outputs an analog voltage signal whose magnitude corresponds to the detected temperature, or a temperature detection element (e.g., a thermistor) whose electrical characteristics change according to temperature. Similar to the heartbeat measurement unit 122 described above, the heartbeat measurement unit 132 includes a sensor that detects the user's heartbeat, a circuit that counts the detected heartbeats, calculates the number of heartbeats per unit time (e.g., 60 seconds), and outputs the result of the calculation to the control unit 11. The heartbeat measurement unit 132 detects the heartbeat, for example, according to photoplethysmography. The battery 133 supplies power to the body temperature measurement unit 131 and the heart rate measurement unit 132. In this embodiment, the battery 133 is a rechargeable battery.

[0013] The storage unit 14 is composed of a non-volatile semiconductor memory or the like. The storage unit 14 stores various programs and data necessary for executing the programs. The communication unit 15 controls communication for transmitting and receiving data to and from external devices such as the terminal device 2 via wireless or wired communication. The timekeeping unit 16 is composed of, for example, a timer, a timekeeping circuit, etc., and keeps track of the current time and acquires time information.

[0014] As shown in Fig. 3, the terminal device 2 is configured to include a control unit 21, an operation unit 22, a storage unit 23, a display unit 24, and a communication unit 25. The control unit 21 is a computer that controls each unit of the terminal device 2. For example, the control unit 21 is configured to include at least one CPU, a RAM (Random Access Memory), etc., and reads out a specified program from among programs stored in the storage unit 23, loads it into the RAM, and executes various processes in cooperation with the loaded program. The operation unit 22 is configured with push button switches, a touch panel attached to the display unit 24, etc. The operation unit 22 outputs operation signals of the push button switches operated by the user and operation signals on the screen of the display unit 24 to the control unit 21.

[0015] The storage unit 23 is configured with a nonvolatile semiconductor memory, an HDD (Hard Disk Drive), or the like. The storage unit 23 stores various programs and data required to execute the programs. The storage unit 23 is not limited to being built into the terminal device 2, and may include an external recording medium detachable from the terminal device 2. For example, the storage unit 23 stores a biological information management program 231. The biological information management program 231 is an application program for acquiring and recording the core body temperature data D1 and heart rate data D2 from the biological information measuring device 1 and displaying them on the display unit 24. The storage unit 23 also stores the core body temperature data D1 and heart rate data D2 acquired from the biological information measuring device 1. The display unit 24 is configured with a display device such as a liquid crystal display or an organic EL (Electro Luminescence) display, and displays data based on the control operation of the control unit 21. The communication unit 25 controls communication for transmitting and receiving data via wireless communication with external devices such as the biological information measuring device 1.

[0016] Next, the operation of the biological information measuring device 1 will be described. As an example, with reference to Fig. 4, the operation of the control unit 11 of the biological information measuring device 1 measuring the core body temperature (ear temperature) and heart rate, which are biological information of the user, will be described. In order to realize the above operation, the control unit 11 executes the biological information measuring process shown in Fig. 4. Here, the biological information measuring process is started, for example, when the control unit 11 receives a measurement start instruction from the terminal device 2 via the communication unit 15.

[0017] 4, when the biological information measurement process starts, the control unit 11 of the biological information measurement device 1 acquires information indicating the remaining battery charge of the battery 123 from the battery 123 of the first wearing device 12, and acquires information indicating the remaining battery charge of the battery 133 from the battery 133 of the second wearing device 13 (step S1). Subsequently, the control unit 11 determines whether the remaining battery charge of the battery 133 of the second wearing device 13 is equal to or greater than the remaining battery charge of the battery 123 of the first wearing device 12 (step S2). Note that the control unit 11 derives the maximum operable times of the battery 123 of the first wearing device 12 and the battery 133 of the second wearing device 13 based on the information indicating the remaining battery charge acquired in step S1. Then, in step S2, the control unit 11 may determine whether the maximum operable time of the battery 133 of the second wearing device 13 is equal to or greater than the maximum operable time of the battery 123 of the first wearing device 12.

[0018] If it is determined in step S2 that the remaining battery charge of the battery 133 of the second wearable device 13 is equal to or greater than the remaining battery charge of the battery 123 of the first wearable device 12 (step S2; YES), the control unit 11 activates the heart rate measurement unit 132 of the second wearable device 13 to start heart rate measurement in the second wearable device 13, and activates the body temperature measurement unit 121 of the first wearable device 12 to start deep body temperature measurement in the first wearable device 12 (step S3). For example, as shown in FIG. 5, when the biological information measurement process is started at timing t0, the remaining battery charge of the battery 133 of the second wearable device 13 at this timing t0 is equal to or greater than the remaining battery charge of the battery 123 of the first wearable device 12, so the control unit 11 activates the heart rate measurement unit 132 of the second wearable device 13 to start heart rate measurement in the second wearable device 13, i.e., the right ear. The control unit 11 also activates the body temperature measurement unit 121 of the first wearable device 12, and starts measuring the core body temperature at the left ear in the first wearable device 12. That is, if the remaining battery charge of the battery 133 of the second wearable device 13 is equal to or greater than the remaining battery charge of the battery 123 of the first wearable device 12, the operation starts from the first state in which the body temperature measurement unit 121 of the first wearable device 12 is activated while the heart rate measurement unit 132 of the second wearable device 13 is activated.

[0019] Furthermore, in step S2, if it is determined that the remaining battery charge of the battery 133 of the second wearing device 13 is not equal to or greater than the remaining battery charge of the battery 123 of the first wearing device 12, that is, the remaining battery charge of the battery 123 of the first wearing device 12 is greater than the remaining battery charge of the battery 133 of the second wearing device 13 (step S2; NO), the control unit 11 activates the heart rate measurement unit 122 of the first wearing device 12 to start heart rate measurement in the first wearing device 12, and activates the body temperature measurement unit 131 of the second wearing device 13 to start deep body temperature measurement in the second wearing device 13 (step S4). In other words, if the remaining battery charge of the battery 133 of the second wearing device 13 is not equal to or greater than the remaining battery charge of the battery 123 of the first wearing device 12, operation starts from a second state in which the heart rate measurement unit 122 of the first wearing device 12 is activated while the body temperature measurement unit 131 of the second wearing device 13 is activated.

[0020] Next, the control unit 11 determines whether a predetermined time has elapsed since the start of measurement of biological information (core body temperature and heart rate) in step S3, step S4, or step S10 (described later) (step S5). Here, the predetermined time in step S5 may be a predetermined time, or may be a time determined according to a maximum operable time derived from the remaining battery power of the first wearable device 12 or the second wearable device 13. If it is determined in step S5 that the predetermined time has not elapsed (step S5; NO), the control unit 11 repeats the determination process of step S5 until the predetermined time has elapsed. On the other hand, if it is determined in step S5 that the predetermined time has elapsed (step S5; YES), the control unit 11 acquires information indicating the remaining battery power of the battery 123 from the battery 123 of the first wearable device 12, and acquires information indicating the remaining battery power of the battery 133 from the battery 133 of the second wearable device 13 (step S6).

[0021] Next, the control unit 11 determines whether the ratio of the remaining battery power between the battery 123 of the first wearable device 12 and the battery 133 of the second wearable device 13 exceeds a threshold (step S7). Here, the remaining battery power ratio is a value obtained by dividing the remaining battery power of the device currently measuring the core body temperature by the remaining battery power of the device currently measuring the heart rate. Therefore, when the first wearable device 12 measures the core body temperature and the second wearable device 13 measures the heart rate, the remaining battery power ratio at this time is derived by dividing the remaining battery power of the first wearable device 12 by the remaining battery power of the second wearable device 13. On the other hand, when the second wearable device 13 measures the core body temperature and the heart rate, the remaining battery power ratio at this time is derived by dividing the remaining battery power of the second wearable device 13 by the remaining battery power of the first wearable device 12.

[0022] If it is determined in step S7 that the remaining battery capacity ratio does not exceed the threshold (step S7; NO), the control unit 11 returns the process to step S6 and repeats the subsequent processes. Also, if it is determined in step S7 that the remaining battery capacity ratio exceeds the threshold (step S7; YES), the control unit 11 stops heart rate measurement (step S8). For example, as shown in FIG. 5, if it is determined that the remaining battery capacity ratio exceeds the threshold at timing t1, the control unit 11 stops heart rate measurement by the heart rate measurement unit 132 of the second wearable device 13. Here, the control unit 11 does not stop deep body temperature measurement by the body temperature measurement unit 121 of the first wearable device 12, and continues to measure the deep body temperature. This is because, as shown in FIG. 5, heart rate measurement by the heart rate measurement unit 122 is not performed in the left ear (first wearable device 12) between timing t0 and timing t1, and there is no effect of temperature rise (heat generation effect) due to the heart rate measurement.

[0023] Next, the control unit 11 determines whether a predetermined time has elapsed since the heart rate measurement was stopped in step S8 (step S9). Here, the predetermined time in step S9 is the time it takes for the temperature to return to a predetermined temperature (e.g., initial temperature +0.02°C) after the heart rate measurement is stopped. The initial temperature refers to the temperature immediately before the temperature starts to rise due to the heart rate measurement, as shown at timings t0, t2, t4, and t6 in FIG. 5 . Information regarding the time it takes for the temperature to return to a predetermined temperature (e.g., initial temperature +0.02°C) after the heart rate measurement is stopped is generated and stored in the storage unit 14, for example, by executing a mode for generating this information during the initial operation of the biological information measurement device 1. Note that if multiple types of heart rate measurement can be performed according to set current values, information regarding the time it takes for the temperature to return to a predetermined temperature after the heart rate measurement is stopped may be stored in the storage unit 14 for each set current value. Furthermore, information regarding the time it takes for the temperature to return to a predetermined temperature after the heart rate measurement is stopped may be stored in the storage unit 14 in advance when the biological information measurement device 1 is shipped.

[0024] If it is determined in step S9 that the predetermined time has not elapsed (step S9; NO), the control unit 11 repeats the determination process of step S9 until the predetermined time has elapsed. If it is determined in step S9 that the predetermined time has elapsed (step S9; YES), the control unit 11 switches the measurement targets of the first and second wearable devices 12 and 13 and starts measurement (step S10). For example, as shown in FIG. 5, if it is determined that the predetermined time has elapsed at timing t2, the control unit 11 activates the heart rate measurement unit 122 of the first wearable device 12 to start heart rate measurement at the first wearable device 12, i.e., the left ear, and activates the body temperature measurement unit 131 of the second wearable device 13 to start deep body temperature measurement at the second wearable device 13, i.e., the right ear. In this way, by switching the measurement targets of the first wearable device 12 and the second wearable device 13 after a predetermined time has elapsed since the heart rate measurement was stopped in step S8, for example, when the measurement of deep body temperature is started by the body temperature measurement unit 131 of the second wearable device 13 at timing t2 (see Figure 5), the body temperature measurement unit 131 of the second wearable device 13 will no longer be affected by the temperature rise (heat generation effect) caused by the heart rate measurement performed by the heart rate measurement unit 132 of the second wearable device 13 up to that point, and the deep body temperature can be measured accurately by the body temperature measurement unit 131 of the second wearable device 13 (the same applies to the measurement of deep body temperature by the body temperature measurement unit 121 of the first wearable device 12 at timing t4).

[0025] Next, the control unit 11 returns the process to step S5 and repeats the subsequent processes. For example, as shown in Fig. 5, if it is determined that the remaining battery capacity ratio exceeds the threshold at time t3 (step S7; YES), the control unit 11 stops heart rate measurement by the heart rate measurement unit 122 of the first wearable device 12. Here, the control unit 11 does not stop deep body temperature measurement by the body temperature measurement unit 131 of the second wearable device 13, and continues to measure the deep body temperature. This is because, from time t2 to time t3, heart rate measurement by the heart rate measurement unit 132 is not being performed in the right ear (second wearable device 13), and therefore there is no effect of temperature rise (heat generation effect) due to the heart rate measurement. If the control unit 11 determines that the predetermined time has elapsed at timing t4 (step S9; YES), the control unit 11 activates the heart rate measurement unit 132 of the second wearable device 13 to start heart rate measurement at the second wearable device 13, i.e., the right ear, and activates the body temperature measurement unit 121 of the first wearable device 12 to start deep body temperature measurement at the first wearable device 12, i.e., the left ear (step S10). In this way, the control unit 11 alternately switches between a first state in which the body temperature measurement unit 121 of the first wearable device 12 is activated while the heart rate measurement unit 132 of the second wearable device 13 is activated, and a second state in which the heart rate measurement unit 122 of the first wearable device 12 is activated while the body temperature measurement unit 131 of the second wearable device 13 is activated. Here, the first state refers to the state from timing t0 to timing t2 and the state from timing t4 to timing t6 shown in FIG. 5. On the other hand, the second state refers to the state between timing t2 and timing t4 shown in FIG.

[0026] The above-described biological information measurement process is terminated when the control unit 11 receives a measurement termination instruction from the terminal device 2 via the communication unit 15. The control unit 11 transmits the deep body temperature data D1 measured by the body temperature measurement unit 121 of the first wearable device 12 or the body temperature measurement unit 131 of the second wearable device 13 and the heart rate data D2 measured by the heart rate measurement unit 122 of the first wearable device 12 or the heart rate measurement unit 132 of the second wearable device 13 to the terminal device 2 via the communication unit 15.

[0027] As described above, the biological information measurement device 1 includes the first wearable device 12 having a body temperature measurement unit (first body temperature measurement unit) 121 that measures the body temperature (core body temperature) of the user (subject) and a heart rate measurement unit (first heart rate measurement unit) 122 that measures the user's heart rate, the second wearable device 13 having a body temperature measurement unit (second body temperature measurement unit) 131 that measures the user's body temperature (core body temperature) and a heart rate measurement unit (second heart rate measurement unit) 132 that measures the user's heart rate, and the control unit 11 that controls the operation of the first wearable device 12 and the second wearable device 13. The control unit 11 alternately switches between a first state in which the body temperature measurement unit 121 of the first wearable device 12 is operated while the heart rate measurement unit 132 of the second wearable device 13 is operated, and a second state in which the heart rate measurement unit 122 of the first wearable device 12 is operated while the body temperature measurement unit 131 of the second wearable device 13 is operated. Therefore, according to the biometric information measuring device 1, it is possible to prevent a difference in the remaining battery power of the first wearable device 12 and the second wearable device 13, thereby extending the time during which heart rate measurement and deep body temperature measurement can be performed simultaneously.

[0028] Furthermore, the control unit 11 of the biological information measuring device 1 acquires information indicating the remaining battery levels of the first and second wearable devices 12 and 13, and determines whether to start operation in the first state or the second state based on the information indicating the remaining battery levels, and determines the timing to switch between the first and second states. Therefore, the biological information measuring device 1 determines the timing to switch between the first and second states while monitoring the remaining battery levels of the first and second wearable devices 12 and 13, thereby making it possible to maintain a favorable balance between the remaining battery levels of the first and second wearable devices 12 and 13. As a result, the biological information measuring device 1 can further extend the time during which heart rate measurement and deep body temperature measurement can be performed simultaneously.

[0029] Furthermore, when switching from the first state to the second state, the control unit 11 of the biological information measurement device 1 stops the operation of the heartbeat measurement unit 132 of the second wearable device 13 from a predetermined time before the timing of switching to the second state (for example, timing t2; see FIG. 5), and when switching from the second state to the first state, stops the operation of the heartbeat measurement unit 122 of the first wearable device 12 from a predetermined time before the timing of switching to the first state (for example, timing t4; see FIG. 5). Therefore, according to the biological information measurement device 1, when the temperature measurement unit 131 of the second wearable device 13 starts measuring the deep body temperature at the timing of switching to the second state, the deep body temperature can be measured accurately by the temperature measurement unit 131 of the second wearable device 13 without being affected by the temperature rise (heat generation effect) caused by the heartbeat measurement performed by the heartbeat measurement unit 132 of the second wearable device 13 up to that point. Furthermore, when the body temperature measurement unit 121 of the first wearable device 12 starts measuring the deep body temperature at the timing of switching to the first state, the body temperature measurement unit 121 of the first wearable device 12 is no longer affected by the temperature rise (heat generation effect) caused by the heart rate measurement performed by the heart rate measurement unit 122 of the first wearable device 12 up to that point, so the body temperature measurement unit 121 of the first wearable device 12 can measure the deep body temperature with high accuracy.

[0030] Furthermore, the control unit 11 of the biological information measuring device 1 sets the time for stopping the operation of the heart rate measuring unit 132 of the second wearing device 13 when switching from the first state to the second state, and also sets the time for stopping the operation of the heart rate measuring unit 122 of the first wearing device 12 when switching from the second state to the first state, based on information related to the recorded time for the body temperature of the user to return to the initial temperature at the start of measurement when the user's heart rate is measured by the heart rate measuring unit 122 of the first wearing device 12 or the heart rate measuring unit 132 of the second wearing device 13. Therefore, according to the biological information measuring device 1, the time for stopping the operation of the heart rate measuring unit 132 of the second wearing device 13 when switching from the first state to the second state can be minimized so as not to affect the measurement of the core body temperature by the body temperature measuring unit 131 of the second wearing device 13 in the second state. In addition, the time for which the operation of the heart rate measurement unit 122 of the first wearable device 12 is stopped when switching from the second state to the first state can be kept to a minimum time that does not affect the measurement of deep body temperature by the body temperature measurement unit 121 of the first wearable device 12 in the first state.

[0031] The description in the above embodiment is an example of the biological information measuring device, biological information measuring method, program, and biological information measuring system according to the present invention, and the present invention is not limited to this. For example, in the above embodiment, when switching from the first state to the second state, the operation of the heartbeat measurement unit 132 of the second wearable device 13 is stopped a predetermined time before the timing of switching to the second state (for example, timing t2; see FIG. 5). However, as shown in FIG. 6, the heartbeat measurement unit 132 of the second wearable device 13 may be operated intermittently from the predetermined time before, thereby gradually reducing the temperature rise due to heartbeat measurement in the heartbeat measurement unit 132. Furthermore, when switching from the second state to the first state, the operation of the heartbeat measurement unit 122 of the first wearable device 12 is stopped a predetermined time before, the timing of switching to the first state (for example, timing t4; see FIG. 5). However, as shown in FIG. 6, the heartbeat measurement unit 122 of the first wearable device 12 may be operated intermittently from the predetermined time before, thereby gradually reducing the temperature rise due to heartbeat measurement in the heartbeat measurement unit 122.

[0032] Furthermore, in the above embodiment, when switching from the first state to the second state, the control unit 11 of the biological information measuring device 1 may stop operation of the heart rate measurement unit 132 of the second wearable device 13 from a predetermined time before the timing of switching to the second state when the user is in a resting state, while intermittently operating the heart rate measurement unit 132 of the second wearable device 13 from a predetermined time before the timing of switching to the second state when the user is in an active state. Furthermore, when switching from the second state to the first state, the control unit 11 may stop operation of the heart rate measurement unit 122 of the first wearable device 12 from a predetermined time before the timing of switching to the first state when the user is in a resting state, while intermittently operating the heart rate measurement unit 122 of the first wearable device 12 from a predetermined time before the timing of switching to the first state when the user is in an active state. The determination of whether the user is in a resting state or an active state is made based on the heart rate measured by the heart rate measurement unit 122 of the first wearable device 12 or the heart rate measured by the heart rate measurement unit 132 of the second wearable device 13.

[0033] Furthermore, in the above embodiment, the control unit 11 of the biometric information measuring device 1 controls the operation of the first wearing device 12 and the second wearing device 13, but for example, the control unit 21 of the terminal device 2 may control the operation of the first wearing device 12 and the second wearing device 13, and alternately switch between a first state in which the body temperature measuring unit 121 of the first wearing device 12 is operated while the heart rate measuring unit 132 of the second wearing device 13 is operated, and a second state in which the heart rate measuring unit 122 of the first wearing device 12 is operated while the body temperature measuring unit 131 of the second wearing device 13 is operated.

[0034] In the above embodiment, the biological information measuring device 1 has been described as a neckband-type device in which the first wearable device 12 and the second wearable device 13 are connected by a cable, but it may also be, for example, a so-called wireless type device in which the first wearable device 12 and the second wearable device 13 are not connected by a cable. In such a case, the control unit 11, the storage unit 14, and the communication unit 15 are provided, for example, within the housing of the first wearable device 12 or the second wearable device 13.

[0035] Furthermore, in the above embodiment, the present invention has been described on the assumption that the power consumption of the heart rate measurement unit 122 in the first wearable device 12 is greater than the power consumption of the body temperature measurement unit 121, and that the power consumption of the heart rate measurement unit 132 in the second wearable device 13 is greater than the power consumption of the body temperature measurement unit 131. However, the present invention can also be applied to cases where the power consumption of the body temperature measurement unit 121 in the first wearable device 12 is greater than the heart rate measurement unit 122, and that the power consumption of the body temperature measurement unit 131 in the second wearable device 13 is greater than the power consumption of the heart rate measurement unit 132. In such a case, in step S3 of the biological information measurement process (see FIG. 4 ), the heart rate measurement unit 122 of the first wearable device 12 is activated to start heart rate measurement in the first wearable device 12, and the body temperature measurement unit 131 of the second wearable device 13 is activated to start deep body temperature measurement in the second wearable device 13. Meanwhile, in step S4, the heart rate measurement unit 132 of the second wearable device 13 is activated to start heart rate measurement in the second wearable device 13, and the body temperature measurement unit 121 of the first wearable device 12 is activated to start deep body temperature measurement in the first wearable device 12. In this case, the remaining battery capacity ratio that is the subject of the determination process in step S7 is the value obtained by dividing the remaining battery capacity of the device that is measuring the heart rate by the remaining battery capacity of the device that is measuring the deep body temperature.

[0036] In the above description, an example has been disclosed in which a nonvolatile semiconductor memory or the like is used as the storage unit 14 as a computer-readable medium for the program according to the present invention, but this is not limiting. Other computer-readable media may also be used, such as information recording media like CD-ROMs. Furthermore, a carrier wave may also be used as a medium for providing the program data according to the present invention via a communication line.

[0037] Furthermore, it goes without saying that the detailed configurations and operations of the components of the vital information measuring device 1 and the terminal device 2 in the above-described embodiment can be modified as appropriate without departing from the spirit of the present invention.
