3. Processing of Measuring Device FIG. 5 is a flowchart showing an example of processing by the measuring device shown in FIG. Below, the measuring device 100 determines the disturbance of the biological clock based on the biological signal corresponding to the state of the biological body of the user H. When the biological clock is disturbed, the notification device 40 notifies the user H of the notification information. Process. In the following, a case where notification information is notified to the user H by the display 4 of the notification unit 40 will be described as a representative.

  The process shown in the flowchart of FIG. 5 can be realized by the control unit 20 reading out and executing the biological information processing program from the storage unit 21 and controlling the driving of each unit of the measuring device 100. For example, when the operation button 15 is operated by the user H, the control unit 20 starts the processing shown in the flowchart. Note that the control unit 20 may start the process shown in the flowchart based on the biological signal output from the sensing unit 5. For example, when the control unit 20 acquires a biological signal based on the pulse wave of the user H output from the pulse wave sensor 51, the control unit 20 may start the process shown in the flowchart. For example, the control unit 20 may start the processing shown in the flowchart after acquiring the designated time information from the time measuring unit 25.

  First, the control unit 20 acquires a biological signal from the sensing unit 5 (step S11), stores the biological signal in the storage unit 21, and accumulates it (step S12). Note that the biological signal is acquired, for example, continuously or at predetermined intervals.

  Next, the control unit 20 determines whether or not the biological clock is disturbed based on the accumulated biological signal, and repeats steps S11 and S12 until it is determined that the biological clock is disturbed (step S13: No). .

  In this specification, the biological clock is a circadian rhythm. The disturbance of the body clock is determined based on, for example, a history of sleep time data including a sleep time and a wake time. Specifically, for example, the user himself / herself inputs a reference wake-up time and sleep time in advance, and calculates the difference between the input wake-up time and sleep time and the actual wake-up time and sleep time However, when the difference exceeds the threshold value, it may be determined that the biological clock is disturbed. Furthermore, the reference wake-up time and sleep onset time may be specified by a moving average of past wake-up time and sleep onset time.

  The time of falling asleep and the time of waking up are obtained based on the signal output from the timer unit 25 and the biological signal output from the sensing unit 5, respectively. Whether the user has fallen asleep or whether he / she has woken up is determined based on, for example, the pulse cycle determined based on the biological signal from the pulse wave sensor 51 and the biological signal from the motion sensor 52, respectively. Is determined using at least one of the body movements.

  In addition, the determination factor of the disturbance of the biological clock is not limited to the sleep time data. For example, the determination elements other than the sleep time data include data relating to the sleep state, data relating to the amount of activity, data relating to the external environment, and registration data registered in advance by the user H.

  Examples of the data related to the sleep state include data such as whether or not the user has awakened during sleep, the number of times of awakening during sleep, and the depth of sleep. Examples of the data relating to the amount of activity include data such as the moving speed of the user H and calories consumed. Examples of the data related to the external environment include data such as environmental temperature, environmental humidity, and weather. Moreover, as registration data, data, such as height, weight, age, and sex, are mentioned, for example.

  The sleep state and the amount of activity are obtained based on the pulse cycle obtained based on the biological signal from the pulse wave sensor 51 and the biological signal from the motion sensor 52, for example, and the body movement of the user H. It is determined using at least one of them. The external environment is obtained by using at least one of a signal from an atmospheric pressure sensor, a signal from an environmental temperature sensor, and a signal from an environmental humidity sensor, for example.

  Next, when it is determined that the biological clock is disturbed (step S13: Yes), the control unit 20 detects the wakeup based on the biological signal and specifies the wakeup time (step S14). In addition, after performing step S14, you may perform step S13 mentioned above.

  Next, the control unit 20 determines whether or not the wake-up time is am (step S15). When it is determined that the wake-up time is in the morning (step S15: Yes), the control unit 20 starts measuring the cumulative power generation amount (step S16), and measures the cumulative power generation amount until a predetermined time is reached (step S17). : No). On the other hand, when the predetermined time has been reached (step S17: Yes), the control unit 20 determines whether or not the accumulated power generation amount has reached the reference value (step S18).

  The cumulative power generation amount is a cumulative value of the power generation amount of the solar cell 3. Moreover, in this embodiment, the start timing of the predetermined time in step S17, that is, the measurement start time in step S16 is the time of getting up. In addition, the end timing of the predetermined time in step S17 may be a time obtained based on the history of detection results from the sensing unit 5, or may be set in advance regardless of the detection results from the sensing unit 5. It may be a long time. For example, the end timing can be obtained based on the past history of the time taken to secure the accumulated power generation amount according to the light amount necessary for resetting the biological clock. Further, for example, the end timing can be set as one hour after the time of getting up. The reference value in step S18 may be obtained based on the history of detection results from the sensing unit 5, or may be set in advance regardless of the detection results from the sensing unit 5.

  Next, when it is determined that the accumulated power generation amount has not reached the reference value (step S18: No), the control unit 20 creates notification information and displays an image indicating the notification information on the display 4 (step S19). On the other hand, when determining that the accumulated power generation amount has reached the reference value (step S18: Yes), the control unit 20 saves the creation of the notification information and ends the process illustrated in FIG.

  The fact that the accumulated power generation amount has not reached the reference value means that the solar radiation amount is not sufficient to reset the body clock. On the other hand, the fact that the accumulated power generation amount has reached the reference value means that the solar radiation was sufficient to reset the body clock.

  The image indicating the notification information is, for example, an image indicating advice information related to the improvement proposal of the biological clock. The image indicating the advice information is, for example, an image indicating information that prompts the user to be exposed to sunlight. Specifically, for example, the control unit 20 causes the display 4 to display an image stating “It is better to move in the sun and sunbathe”.

  If it is determined in step S15 that the wake-up time is not in the morning but in the afternoon (step S15: No), the control unit 20 creates information having contents different from the notification in step S19 described above. An image indicating information is displayed on the display 4 (step S20).

  The image indicating the information is, for example, an image indicating information that prompts improvement of the wake-up time. Specifically, for example, the control unit 20 causes the display 4 to display an image indicating that “it is better to wake up in the morning to improve life rhythm”.

  The processing by the measuring device 100 shown in FIG. 5, that is, the biological information processing method has been described above.

  As described above, the measuring device 100 that is an example of the “biological information measuring device” includes the solar cell 3, the notification unit 40, and a sensing unit that outputs a biological signal (biological information) according to the state of the living body of the user H. 5 and a control unit 20 which is a processor (see FIG. 4). Further, as described above, the control unit 20 determines whether the user's body clock is disturbed based on the biological signal in step S13, and detects the wake-up of the user H based on the biological signal in step S14 (see FIG. 5). . Further, when the biological clock is disturbed, the control unit 20 measures the accumulated power generation amount of the solar cell 3 after waking up in step S16, generates notification information based on the accumulated power generation amount in step S19, and notifies the notification unit 40. Notify the notification information. In the above description, the notification information is notified by the display 4 in the notification unit 40 as a representative.

  According to the measuring device 100, when the biological clock is disturbed, the notification information is notified, so that it is possible to prompt the user H to be exposed to light directly or indirectly. Therefore, usability can be improved.

  Moreover, when displaying the image which shows notification information on the display 4 like this embodiment, the image which shows notification information is an image which shows the advice information regarding the improvement proposal of a biological clock, as mentioned above. The image indicating the advice information is, for example, an image indicating information that prompts the user to be exposed to sunlight. The control unit 20 can prompt the user H to be exposed to light directly by causing the display 4 to display an image indicating information that prompts the user to be exposed to sunlight. In addition, the image which shows the information which encourages exposure to sunlight may be represented by a character, and may be represented not by a character but by a symbol.

  The image indicating the notification information may be an image indicating the notification information based on the accumulated power generation amount, and may be an image other than the image indicating the advice information. Specifically, the image indicating the notification information may be, for example, an image indicating information indicating that the biological clock is disturbed or an image indicating information indicating that the amount of sunlight is insufficient. The control unit 20 can prompt the user H to receive light indirectly by displaying the image on the display 4.

  Further, the control unit 20 may notify the user H of the notification information by the notification unit 40. Therefore, the control unit 20 causes the vibration unit 71 to generate a vibration indicating the notification information, or causes the sound generation unit 72 to generate a sound indicating the notification information, instead of causing the display 4 to display an image indicating the notification information. It may be generated. When notifying by the vibration unit 71, for example, the vibration pattern is changed according to the notification content. Moreover, when notifying by the sound generation part 72, the kind of sound is changed, for example. The control unit 20 may notify the user H of the notification information by combining two or more of the image indicating the notification information, the vibration generated by the vibration unit 71, and the sound generated by the sound generation unit 72. This makes it easier for the user H to notice that the image indicating the notification information is displayed. In particular, as described above, by notifying the notification information using the display 4, the user H is preferable in that the notification contents can be grasped in detail.

  Further, as described above, when the control unit 20 determines that the user H got up in the morning (step S15), the control unit 20 measures the accumulated power generation amount up to a predetermined time after the user H gets up (steps S16 and S17). ) When the accumulated power generation amount does not reach the reference value (step S18: Yes), the notification unit 40 is notified of the notification information (step S19).

  When the control unit 20 determines that the accumulated power generation amount after waking up has not reached the reference value, that is, when the solar radiation amount sufficient for resetting the body clock is not received, the notification information is notified, so usability is improved. It can be improved further. On the other hand, when it is determined that the accumulated power generation amount after waking up has reached the reference value, that is, when the amount of solar radiation is sufficient for resetting the biological clock, notification of the notification information is omitted (step S18: No). Since such notification is omitted, the troublesomeness for the user H can be reduced.

  Further, as described above, in step S15, the control unit 20 determines whether the wake-up time is morning or afternoon (step S15).

  By making such a determination, the control unit 20 can notify the contents suitable for each of the morning wake-up time and the afternoon wake-up time. Therefore, usability can be further improved. For example, as described above, when the control unit 20 gets up in the afternoon, the control unit 20 gives a notification different from that in the case of getting up in the morning. If it is determined that the user has woken up in the morning, the control unit 20 causes the display 4 to display an image indicating the notification information based on the accumulated power generation amount, for example, as described above. On the other hand, when it determines with having risen in the afternoon, the control part 20 displays on the display 4 the content which urges to change a life rhythm and to make it morning.

  Further, as described above, the control unit 20 determines the disturbance of the biological clock based on the history of biological signals accumulated within a predetermined period. Specifically, a biological signal is accumulated in step S12, and the disturbance of the biological clock is determined in step S13 based on the accumulated history of the biological signal.

  By using the history of the biological signal, it is possible to increase the accuracy of the determination as compared with the case where the history is not used. For example, the accuracy of the determination can be improved as compared with the case where the disturbance of the biological clock is determined based only on the content registered in advance by the user H without using the biosignal history.

  In step S13, the control unit 20 determines whether the biological clock is disturbed based on the user's sleep time and the wake-up time.

  According to this determination, the control unit 20 can easily determine the disturbance of the biological clock based only on the time without requiring complicated calculation.

  Furthermore, as described above, the control unit 20 may disturb the biological clock based on at least one of whether the user has awakened during sleep, the number of times the user has awakened, and the depth of sleep of the user. Determine.

  According to this determination, the determination accuracy can be further improved as compared with the case where the determination is based only on the sleep time and the wake-up time. In addition, the accuracy of determination can be further increased by using all of the awakening frequency and the sleep depth as determination elements.

  Furthermore, as described above, the control unit 20 may determine the disturbance of the biological clock using at least one of data relating to the amount of activity, data relating to the external environment, and registration data registered in advance by the user H. . By adding such data as a determination element, the accuracy of determination can be further increased.

  As described above, the processing of the measuring device 100 has been described by taking the flowchart shown in FIG. 5 as an example. For example, the control unit 20 performs steps S11 and S12 while performing the processing related to each step after step S13. You may continue.

  If it is determined that the accumulated power generation amount has not reached the reference value (step S18: No), the control unit 20 refers to the external environment and the like to determine the external situation before creating notification information in step S19. You may perform the step to do.

  More specifically, for example, if the control unit 20 determines in step S18 that the accumulated power generation amount has not reached the reference value, the external environment obtained based on the signal output from the sensing unit 5 and the GPS reception The position information obtained based on the signal output from the unit 62 is referred to. Next, the control unit 20 determines temperature, humidity, weather, and the like and an external situation such as whether indoor or outdoor based on the external environment and position information. Thereafter, in step S19, notification information corresponding to the external situation is created. For example, if the control unit 20 determines that the weather is rainy or the like and the environment cannot be exposed to sunlight, the control unit 20 causes the display 4 to display an image indicating that the user is urged to move to a place with high illuminance. In addition, since the light of the indoor lamp represented by a fluorescent lamp etc. is very weak compared with sunlight (sunlight), the notification which considered this is performed. Further, the control unit 20 may create additional advice information related to improving the biological clock, such as having a meal, and display an image indicating that on the display 4. In addition, if the control unit 20 wakes up in the morning but determines that it is before the sunrise time, it may create information indicating that it is better to be exposed to sunlight after sunrise in step S19. In this manner, the control unit 20 can create notification information suitable for an external situation by determining the external situation with reference to the external environment and position information.

  Moreover, the control part 20 may determine whether it is after sunrise in addition to whether it is morning in step S15. For example, when the wake-up time is after sunrise and in the morning, the control unit 20 proceeds from step S15 to step S16. Specifically, for example, the case where the wake-up time is 8:00 am corresponds to the case after sunrise and in the morning. On the other hand, when the wake-up time satisfies either one after sunrise or not in the morning, the control unit 20 proceeds from step S15 to step S20. Specifically, for example, the case where the wake-up time is 3:00 pm corresponds to the case where it is not after sunrise. In this case, the control unit 20 proceeds from step S15 to step S20.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. FIG. 6 is a flowchart illustrating an example of processing performed by the measuring device according to the second embodiment.

  The present embodiment is the same as the first embodiment described above except that the determination of the passage of sunrise time is mainly added in the processing by the measuring device.

  In the following description, the second embodiment will be described with a focus on differences from the above-described embodiment, and description of similar matters will be omitted. In FIG. 6, the same reference numerals are given to the same configurations as those in the above-described embodiment.

  In the flowchart illustrated in FIG. 6, when the control unit 20 determines that the wake-up time is morning (step S15: Yes), the control unit 20 determines whether or not the sunrise time has elapsed (step S21). When it is determined that the sunrise time has passed (step S21: Yes), the control unit 20 starts measuring the accumulated power generation amount (step S16).

  In addition, when the wake-up time is after the sunrise time, the control unit 20 sets the start timing of the predetermined time in step S17 as the wake-up time. Specifically, when the wake-up time is 8:00 am, the control unit 20 sets the start timing of the predetermined time in step S17, that is, the measurement start time in step S16 as the sunrise time. On the other hand, when the wake-up time is before the sunrise time, the control unit 20 sets the start timing of the predetermined time in step S17 as the sunrise time. Specifically, when the wake-up time is 3:00 am, the control unit 20 sets the start timing of the predetermined time in step S17 as the sunrise time. Thus, the control unit 20 can measure the accumulated power generation based on sunlight more accurately by using the sunrise time as well as the wake-up time than when the sunrise time is not used.

  Usability can also be improved by the second embodiment as described above.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. FIG. 7 is a flowchart illustrating an example of processing performed by the measuring device according to the third embodiment.

  The present embodiment is mainly the same as the first embodiment described above except that in the processing by the measuring device, the determination as to whether or not the wake-up time is am is omitted.

  In the following description, the third embodiment will be described with a focus on differences from the above-described embodiment, and description of similar matters will be omitted. Moreover, in FIG. 7, the same code | symbol is attached | subjected about the structure similar to embodiment mentioned above.

  In the flowchart shown in FIG. 7, the determination (step S15) of whether or not the wake-up time in the first embodiment is am is omitted. Therefore, in this embodiment, if the control part 20 determines whether the biological clock is disturb | confused (step S13: Yes), the time of waking up will be specified (step S14), and the measurement of accumulated electric power generation will be started. (Step S16).

  In the present embodiment, the control unit 20 measures the accumulated power generation amount and makes a notification based on the accumulated power generation amount regardless of the time when the user H gets up. Whether the user wakes up in the morning or wakes up in the afternoon, the control unit 20 performs notification based on the accumulated power generation amount so that only the morning user H who often wakes up in the morning. In addition, it is possible to encourage improvement of the body clock even to the night-type user H who often wakes up in the afternoon. In addition, it is preferable that the notification based on the accumulated power generation amount in the present embodiment refers to the time of wake-up and has contents according to the time.

  Usability can also be improved by the third embodiment as described above.

  As mentioned above, although this invention was demonstrated based on embodiment of illustration, this invention is not limited to these. In addition, the configuration of each part of the present invention can be replaced with any configuration that exhibits the same function as that of the above-described embodiment, and any configuration can be added.

  In the above-described embodiment, the measurement device that can be attached to the user has been described as an example. However, the measurement device may not be attached. In the above-described embodiment, the measurement device that can be carried by the user has been described as an example. However, the measurement device may not be portable.

  In the above-described embodiment, the electronic timepiece receives GPS satellite signals in order to obtain time information. However, the electronic timepiece receives other signals in order to obtain time information. You may make it do. For example, in order to obtain time information, signals of Galileo, Glonus, SBAS (Satellite-Based Augmentation System), and Quasi-Zenith Satellite (Michibiki) may be used in addition to GPS. These signals are collectively called GNSS (Global Navigation Satellite System).
