(Problems to be solved by the invention)
According to the conventional mood (emotion) determination device, although the mood appearing within a certain short time can be estimated, the mood estimated over a long period (for example, over one day) can be estimated within that period. Cannot judge whether it feels good or bad overall. For example, when there are times when you feel unwell (when you are uncomfortable) and when you are feeling well (when you are comfortable), according to a conventional mood determination device, you can feel good or bad at any given time. Although it can be determined, when viewed in units of one day, it cannot be determined whether the day is a good day or a bad day as a whole.

  The present invention provides a mood determination device configured to be able to determine whether a mood during the period is good or bad from a mood transition estimated over a relatively long period of time. For the purpose.

(Means for solving the problem)
According to the present invention, a biological signal acquisition unit (51) that acquires a biological signal that affects a subject's mood, and a mood value that indexes the subject's mood is calculated based on the biological signal acquired by the biological signal acquisition unit. The mood value information transition that is the transition of the information representing the mood value by monitoring the mood value computing section (52) and the information representing the mood value calculated by the mood value computing section during the day in association with the time Providing a mood determination device (5) comprising: a monitoring unit (54) for acquiring a mood value; and a mood determination unit (55) for determining the mood of the subject in units of one day based on the mood value information transition To do.

  According to the present invention, the information representing the mood value is monitored by associating the information representing the mood value of the subject calculated during the day with the time and monitoring. Based on the transition of information representing the mood value of the subject for one day, whether the subject feels good or bad on a daily basis is determined. As described above, according to the present invention, it is possible to determine whether the subject feels good or bad comprehensively when viewed on a daily basis.

  In the above invention, the information representing the mood value may be the mood value itself or information obtained by processing the mood value, for example, a mood rank described later. In the above invention, “monitoring information representing mood values in association with time” means storing information representing mood values in time series in association with time.

  In addition, the mood determination device according to the present invention stratifies the range of possible mood values into a plurality of mood ranks, and the mood value calculated by the mood value calculation unit among the stratified mood ranks belongs It is good to have the mood rank setting part (53) which sets a mood rank with respect to the mood value. Moreover, it is preferable that the monitoring unit creates a mood rank time chart representing the transition of the mood rank by monitoring the mood rank set by the mood rank setting unit during the day in association with the time. And a mood determination part is good to determine the subject's mood in the unit of 1 day based on the time chart of a mood rank.

  In this case, the mood determination unit calculates a discomfort occurrence frequency calculation process (S302) that calculates a discomfort occurrence frequency (F) that is a frequency at which the transition of the mood rank shown in the time chart of the mood rank falls below the threshold rank in the discomfort direction. And a determination process (S303, S304, S305) for determining the mood of the subject in units of one day based on whether or not the unpleasant occurrence frequency is equal to or higher than a predetermined threshold frequency (Fth). Good. Here, “below the threshold rank in the uncomfortable direction” means that the mood rank represented by the mood rank time chart is moving in a region representing a more unpleasant mood than the mood represented by the threshold rank. means. According to this, it is possible to determine the mood of the subject in units of one day based on the number of times (frequency) that the subject felt uncomfortable during the day.

  In the above invention, the “threshold rank” can be set to any mood rank, but is preferably set to a mood rank that feels somewhat uncomfortable. By setting the threshold rank in this way, the frequency with which the subject is uncomfortable can be accurately calculated.

  Also, the mood determination unit discomforts the reference rank in which the time (T0) when the transition of the mood rank shown in the time chart of the mood rank falls below the threshold rank in the uncomfortable direction is a mood rank higher in the comfort direction than the threshold rank. An unpleasant time ratio calculation process (S502) for calculating a ratio of the time less than the direction (t0) as the unpleasant time ratio (RT), and the unpleasant time ratio is equal to or greater than a predetermined threshold time ratio (RTth) Or a determination process (S503, S504, S505) for determining the mood of the subject in units of one day based on whether or not. Here, “a mood rank higher in the comfortable direction than the threshold rank” means a mood rank representing a more comfortable mood than the mood represented by the threshold rank. According to this, based on the time when the subject feels uncomfortable during the day, the mood of the subject can be determined on a daily basis.

  In addition, the mood determination unit discomforts a reference rank in which an area (S0) in which the transition of the mood rank shown in the time chart of the mood rank is lower than the threshold rank in the uncomfortable direction is a higher mood rank in the comfort direction than the threshold rank. An unpleasant area ratio calculation process (S602) for calculating a ratio of the area below the direction (s0) as an unpleasant area ratio (RS), and the unpleasant area ratio is equal to or greater than a predetermined threshold area ratio (RSth). Or a determination process (S603, S604, S605) for determining the mood of the subject in units of one day based on whether or not. Here, “the area where the mood rank transition is below the threshold rank in the uncomfortable direction” is the area of the area where the mood rank transition is below the threshold rank in the uncomfortable direction. In addition, the mood rank transition is the threshold rank. Is the time integral value of the absolute value of the difference between the mood rank and the threshold rank. In addition, “the area where the mood rank transition is below the reference rank in the uncomfortable direction” is the area of the area where the mood rank transition is below the reference rank in the uncomfortable direction, and moreover, the mood rank transition is the reference rank. In the region below the unpleasant direction, it is the time integral value of the absolute value of the difference between the mood rank and the reference rank. According to this, it is possible to more accurately determine the mood of the subject in units of one day based on the time that the subject felt uncomfortable during the day and the degree of discomfort.

  In addition, the mood determination system according to the present invention creates an advice information creation unit (56) that creates advice information that prompts the return of the time when the subject is uncomfortable from a mood value information transition (for example, a mood rank time chart). It is good to have. According to this, by providing advice information created by the advice information creation unit to the target person, it is possible to return to the time when the target person was uncomfortable, thereby encouraging awareness of the event that occurred at that time. And we can rethink the event.

  The mood determination system according to the present invention also includes a data storage unit (57) for storing mood value information transition (for example, a mood rank time chart) for a plurality of days, and a plurality of days stored in the data storage unit. And a transition pattern learning unit (58) that learns an average transition pattern that is an average mood value information transition pattern based on the mood value information transition. Then, the advice information creation unit may extract a part where the mood value information transition shows a transition different from the average transition pattern as a singular point, and create advice information that prompts regression regarding the occurrence time of the extracted singular point. According to this, when there is a change in mood that is different from normal, by providing the target person with advice information that prompts the regression, the subject is encouraged to be aware of the event that occurred at that time, and the event is reconsidered. be able to.

  In addition, the mood determination system according to the present invention has an authentication function, and when authentication is canceled, an information providing unit (59) that provides a determination result by the mood determination unit, and information provided from the information providing unit And a display unit (41) for displaying. According to this, the authentication function of the information providing unit can prevent information related to the subject's mood from being leaked to others. In addition, when authentication is canceled, the information provider provides the subject with the mood determination result via the display unit, so that the subject is informed of the overall mood of the day. can do.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a schematic configuration of a mood information providing system including a mood determination device according to the present embodiment. As shown in FIG. 1, the mood information providing system 1 according to the present embodiment includes a biological signal detection sensor 2, a repeater (modem) 3, an external mobile device 4, and a server 5. The server 5 corresponds to the mood determination device of the present invention. The external mobile device 4 can also be included in the mood determination device.

  The biological signal detection sensor 2 detects a biological signal that influences the subject's mood, which is a biological signal of the subject (user) for which the mood information providing system 1 provides the mood information. The biological signal detection sensor 2 may be a sensor group including a plurality of sensors that individually detect a plurality of biological signals of the subject. As a plurality of sensors constituting the sensor group, a heartbeat signal detection sensor that detects a heartbeat signal of the subject, a pulse wave signal detection sensor that detects a pulsewave signal of the subject, a skin potential signal of the subject (here, skin potential) The skin potential signal detection sensor for detecting the respiratory information (respiration rate, breathing interval, etc.), the body temperature detection sensor for detecting the body temperature (skin temperature), Examples include a blood pressure detection sensor, a body motion detection sensor that detects body motion (acceleration), and the like.

  The biological signal detection sensor 2 may be worn by the subject as a wearable sensor, or may be installed at a place where the subject stays. For example, the biological signal detection sensors 2 may be installed in the subject's home, a bed used when the subject sleeps, a vehicle seat possessed by the subject, and the like. The biological signal detection sensor 2 is configured to be able to communicate with the repeater 3 by wired communication means or wireless communication means.

  The biological signal detection sensor 2 includes a sensor unit 21, an operation switch 22, and a detection circuit 23. The biological signal detection sensor 2 operates when the operation switch 22 is in the ON state, and the operation of the biological signal detection sensor 2 stops when the operation switch 22 is in the OFF state. When the operation switch 22 is changed from the OFF state to the ON state, the detection circuit 23 executes a biological signal detection process.

  FIG. 2 is a flowchart showing the flow of the biological signal detection process performed by the detection circuit 23 of the biological signal detection sensor 2. According to the processing flow shown in FIG. 2, the detection circuit 23 first determines whether or not a biological signal is input in step 101 (hereinafter, step is abbreviated as “S”) in FIG. 2. When the biological signal is input (S101: Yes), the input biological signal is detected (S102), and the detected biological signal is transmitted in association with the detection time (and date) (S103). Next, it is determined whether or not the operation switch 22 is in an OFF state (S104). When the operation switch 22 is in the ON state (S104: No), the detection circuit 23 returns the process to S101 and repeats the above process. On the other hand, when the operation switch 22 is in the OFF state (S104: Yes), the detection circuit 23 ends this routine.

  If it is determined in S101 of FIG. 2 that no biological signal is input (S101: No), the detection circuit 23 advances the process to S105 and activates a built-in timer set for a predetermined time. Next, in S106, it is determined whether or not the built-in timer has counted up. When the count is not up (S106: No), the detection circuit 23 returns the process to S101, and repeats the determination of whether or not a biological signal is input. On the other hand, when the built-in timer counts up (S106: Yes), the detection circuit 23 cannot detect the biological signal because the biological signal detection sensor 2 is not attached (in the case of a wearable sensor). If it is determined, this routine is terminated.

  When the detection circuit 23 of the biological signal detection sensor 2 executes the above-described processing, the biological signal is sequentially detected, and the detected biological signal is associated with the detection time (and date), and the repeater 3 is transmitted.

  The repeater 3 sequentially receives the subject's biological signal transmitted from the biological signal detection sensor 2. Further, the repeater 3 is configured to be capable of wireless communication with the server 5. The repeater 3 transmits the biological signal of the subject received from the biological signal detection sensor 2 to the server 5 by wireless communication.

  The external mobile device 4 is connected to the repeater 3 by wireless communication. Therefore, the external mobile device 4 can transmit and receive with the server 5 via the repeater 3. The external mobile device 4 and the server 5 can also be configured to be able to directly transmit and receive. In this case, the repeater 3 is omitted, and the biological signal detected by the biological signal detection sensor 2 is directly transmitted to the server 5.

  The external mobile device 4 has a display screen 41. The subject can input predetermined information on the display screen 41. Information input to the display screen 41 is transmitted to the server 5 via the repeater 3. Further, the information transmitted by the server 5 is displayed on the display screen 41 of the external mobile device 4 via the repeater 3. Thereby, the information from the server 5 is provided to the target person. Examples of the external mobile device 4 include a smartphone or a tablet terminal.

  The server 5 is hardware that can perform data transmission / reception, data storage / storage, data analysis / determination / integration processing, and the like. FIG. 3 is a block diagram illustrating a functional configuration of the server 5. As shown in FIG. 3, the server 5 includes a biological signal acquisition unit 51, a mood value calculation unit 52, a mood rank setting unit 53, a monitoring unit 54, a mood determination unit 55, an advice information creation unit 56, The data storage unit 57, the transition pattern learning unit 58, and the information providing unit 59 are included.

  The biological signal acquisition unit 51 acquires the biological signal of the subject. The mood value calculation unit 52 calculates a mood value that is a value obtained by indexing the mood of the subject based on the biological signal acquired by the biological signal acquisition unit 51. Here, in this specification, the “feeling” of the subject is used as a concept representing whether the subject is comfortable or uncomfortable. The “mood value” is a value obtained by indexing mood.

  The mood rank setting unit 53 sets a mood rank corresponding to the magnitude of the mood value calculated by the mood value calculation unit 52. The mood rank will be described later. The monitoring unit 54 monitors (monitors) the mood rank set for the subject's mood value, and creates a time chart representing the transition of the mood rank set during the day. The mood determination unit 55 determines the mood of the subject in units of one day based on the mood rank time chart created by the monitoring unit 54.

  The advice information creation unit 56 is a time chart created by the monitoring unit 54, or a comparison of a time chart created by the monitoring unit 54 and an average transition pattern learned by a transition pattern learning unit 58 to be described later. Create advice information The data storage unit 57 stores and stores various data. The transition pattern learning unit 58 learns the average pattern (average transition pattern) of the transition pattern of the mood rank of the subject throughout the day. The information providing unit 59 outputs necessary data when receiving a data inquiry signal.

  In the mood information providing system 1 configured as described above, when the biological signal detection sensor 2 detects a biological signal as described above, the biological signal is transmitted to the server 5 via the relay 3. The biological signal transmitted to the server 5 is acquired by the biological signal acquisition unit 51 of the server 5. The biological signal acquisition unit 51 outputs the acquired biological signal to the mood value calculation unit 52. When a biological signal is input, the mood value calculation unit 52 calculates a mood value obtained by indexing the subject's mood based on the input biological signal.

Mood fluctuations (pleasant and unpleasant fluctuations) appear in fluctuations of specific biological signals (for example, heart rate signals, skin potential signals (= sweating amount)). Therefore, it is possible to estimate whether the mood is good or bad from a specific biological signal, and to quantitatively grasp the mood (comfortable or uncomfortable) by indexing the estimated good or bad mood Can do. In this case, the mood value calculation unit 52 sets the logarithmic odds (ln (p / (1-p)) of the occurrence probability p of the event of feeling good (comfortable) as a dependent variable and the biological signal x _k as an independent variable. logistic regression model equation ln as shown in the following _{(p i / (1-p} i)) = α 0 + α 1 x 1, i + ··· + α k x k, i
i = 1,... n
Occurrence probability p is calculated by logistic regression analysis using. Here, k indicates the number of types of data called the number of dimensions, and i indicates the number of data. Incidentally, the optimum regression coefficient alpha _k of the biological signal x _k is determined in advance. The mood value is obtained as a value within a range of 0 to 100 (%) by multiplying the occurrence probability p by 100, for example. In this case, the smaller the mood value, the more the subject feels uncomfortable, and the larger the mood value, the more comfortable the subject feels. The mood value calculation unit 52 outputs the calculated mood value to the mood rank setting unit 53.

  When the mood rank setting unit 53 inputs a mood value, the mood rank setting unit 53 sets a mood rank corresponding to the magnitude of the mood value for the input mood value. Here, the mood rank setting unit 53 divides the mood value into 10 levels by dividing the range of possible mood values (0 to 100 in the above example) into 10 levels, and each rank is divided into 10 ranks. Mood ranks 1-10 are given. And the mood rank setting part 53 sets the mood rank to which the input mood value belongs among the several (10) mood ranks classified as mentioned above with respect to the input mood value.

  For example, the range of mood values 0-10 corresponds to mood rank 1, the range of mood values 11-20 corresponds to mood rank 2, the range of mood values 21-30 corresponds to mood rank 3, and the mood value 31 The range of -40 corresponds to mood rank 4, the range of mood values 41-50 corresponds to mood rank 5, the range of mood values 51-60 corresponds to mood rank 6, and the range of mood values 61-70 is Corresponds to mood rank 7, range of mood values 71-80 corresponds to mood rank 8, range of mood values 81-90 corresponds to mood rank 9, range of mood values 91-100 corresponds to mood rank 10. Thus, the range of possible mood values is stratified. In this case, if the input mood value is 55, the mood rank 6 is set for the mood value.

Thus, the magnitude of the mood value is reflected in the mood rank. Accordingly, the lower the mood rank, the more the subject feels uncomfortable, and the higher the mood rank, the more comfortable the subject feels. Table 1 shows the relationship between the mood rank and the subject's mood (pleasant / uncomfortable) state.

  The mood rank setting unit 53 sets the mood rank for the input mood value as described above, and then outputs the set mood rank to the monitoring unit 54. The mood rank setting unit 53 may set a mood rank for each mood value each time the mood value is input, but the average mood value input during a predetermined short time period may be set. You may set a mood rank. For example, the mood rank may be set for the average value of the mood values input during 10 minutes. In this case, the mood rank is output from the mood rank setting unit 53 to the monitoring unit 54 every 10 minutes.

  The monitoring unit 54 performs a monitoring process. FIG. 4 is a flowchart showing the flow of the monitoring process routine executed by the monitoring unit 54. This routine is repeatedly executed every predetermined short time. When this routine is activated, the monitoring unit 54 first determines whether or not a mood rank is input from the mood rank setting unit 53 in S201 of FIG. When the mood rank is not input (S201: No), the monitoring unit 54 ends this routine. On the other hand, when the mood rank is input (S201: Yes), the monitoring unit 54 determines whether or not a real-time transmission request signal is input (S202). The real-time transmission request signal is a signal that the target person transmits to the server 5 through the external mobile device 4 when the user wants to know the current mood. When the real-time transmission request signal is input (S202: Yes), the monitoring unit 54 transmits the mood rank input from the mood rank setting unit 53 and the mood corresponding to the mood rank to the repeater 3 (S203). The repeater 3 transmits the received mood rank and the mood corresponding to the mood rank to the external mobile device 4. The external mobile device 4 displays the received mood rank and mood on the display screen 41. Thereby, the subject can know the mood in real time.

  After transmitting the mood rank and the mood corresponding to the mood rank in S203, the monitoring unit 54 advances the process to S204. If it is determined in S202 that a real-time transmission request signal has not been input (S202: No), the monitoring unit 54 skips the process of S203 and advances the process to S204. In S204, the monitoring unit 54 stores the input mood rank in association with the input time. By repeatedly executing the process of S204, the mood rank of the subject is stored in the monitoring unit 54 in time series. That is, the mood rank of the subject is monitored.

  Next, the monitoring unit 54 determines whether or not the current time is an update time in S205. The update time is always a constant time so that the time from the previous update time to the current update time is 24 hours. The update time can be set to an arbitrary time, but the update time may be set to a time when the date changes (midnight). In addition, the update time can be set to a time later than the sleep start time of the subject person. When it is determined in S205 that the current time is not the update time (S205: No), the monitoring unit 54 returns the process to S201. On the other hand, if it is determined in S205 that the current time is the update time (S205: Yes), the monitoring unit 54 stores the mood rank stored between the previous update time and the current update time, that is, during the day. Are read out (S206). Next, in S207, a mood rank time chart is created based on the read mood series time series data for one day.

  FIG. 5 is a diagram showing an example of a mood rank time chart created by the process of S207. This time chart is created by graphing the mood rank according to the time. The horizontal axis of the time chart shown in FIG. 5 is time (hour), and the vertical axis is mood rank. In the example shown in FIG. 5, the mood rank is displayed every 10 minutes. As shown in FIG. 5, the mood rank varies with time. For example, at 10 o'clock, the mood rank has dropped to 1, indicating that the subject is very uncomfortable. Moreover, the mood rank between 14:00 and 15:00 is very high, and it turns out that a subject's mood is comfortable in this time slot | zone. In the example shown in FIG. 5, the transition of the mood rank from 0 o'clock to 6 o'clock and from 23 o'clock to 24 o'clock is not shown. The reason is that the sleeping time of the subject is from 23:00 to 6 o'clock, so that the biological signal detection sensor is removed from the subject during that time period, or the operation switch of the biological signal detection sensor is turned off. Because.

  The mood rank shown in the time chart created by the monitoring unit 54 as shown in FIG. 5 is information representing a mood value. The time chart shown in FIG. 5 is time series data of mood ranks set for the mood values calculated by the mood value calculation unit during one day (from the previous update time to the current update time). Therefore, it can be said that this time chart is a transition of information (mood rank) representing the mood value of the subject set during the day. This time chart corresponds to the mood value information transition of the present invention. Therefore, the monitoring unit 54 acquires the mood value information transition by creating a time chart of the mood value.

  After creating the mood rank time chart in S207, the monitoring unit 54 outputs the created mood rank time chart (S208). The outputted mood rank time chart is input to the mood determination unit 55. Thereafter, the monitoring unit 54 ends this routine.

  Moreover, the mood determination part 55 performs a mood determination process. FIG. 6 is a flowchart showing the flow of the mood determination processing routine executed by the mood determination unit 55. This routine is repeatedly executed every predetermined short time. When this routine is activated, the mood determination unit 55 first determines whether or not a mood rank time chart is input from the monitoring unit 54 in S301 of FIG. When the mood rank time chart is not input (S301: No), the mood determination unit 55 ends this routine. On the other hand, when the mood rank time chart is input (S301: Yes), the mood determination unit 55 advances the process to S302.

  In S302, the mood determination unit 55 obtains the unpleasant occurrence frequency F from the input mood rank time chart. The unpleasant occurrence frequency F is the number of times the mood rank transition shown in the input mood rank time chart enters the unpleasant zone. The “discomfort zone” means a region where the subject feels uncomfortable, and the discomfort zone and a zone that is not the discomfort zone are partitioned by a threshold rank. In the present embodiment, the mood rank (threshold rank) of the threshold of the unpleasant zone is set to 4. Therefore, in this embodiment, the discomfort zone is an area below the mood rank 4 in the mood rank time chart. The unpleasant occurrence frequency F is the frequency (number of times) that the mood rank falls below the threshold rank (mood rank 4) in the uncomfortable direction (direction in which the mood rank decreases), that is, the number of times that the mood rank is 3 or less. In the example shown in FIG. 5, the number of times that the mood rank falls below the threshold rank 4 during one day (24 hours) is 5 times as shown by the numbers surrounded by circles at the bottom of the time chart of FIG. 5. . Therefore, the discomfort occurrence frequency F is 5. The process of S303 corresponds to the discomfort occurrence frequency calculation process of the present invention.

  Subsequently, the mood determination unit 55 advances the process to S303. In S303, it is determined whether or not the discomfort occurrence frequency F obtained in S302 is equal to or higher than the threshold frequency Fth. The threshold frequency Fth is set in advance as a value with which it is possible to determine that the subject's mood is uncomfortable in a comprehensive manner when the discomfort occurrence frequency F is higher than that per day. The threshold frequency Fth can also be set based on the average value of the discomfort occurrence frequency F obtained from the time chart of the subject's past mood rank.

  When the unpleasant occurrence frequency F is equal to or higher than the threshold frequency Fth (S303: Yes), the mood determination unit 55 sets the mood state to “unpleasant” (S304). On the other hand, when the unpleasant occurrence frequency F is less than the threshold frequency Fth (S303: No), the mood determination unit 55 sets the mood state to “comfortable” (S305). As used herein, “mood state” refers to a state of mood that can be comprehensively viewed on a daily basis. Therefore, when the mood state is “uncomfortable”, it indicates that the subject's day was generally uncomfortable, and when the mood state is “comfortable”, the subject's day was generally comfortable. Represents that. The mood determination unit 55 sets the mood state to “uncomfortable” or “comfortable” in S304 or S305, whereby the mood of the subject in units of one day is determined. The processes of S303, S304, and S305 correspond to the determination process of the present invention.

  After the mood determination unit 55 sets the mood state in S304 or S305, the process proceeds to S306, the mood rank time chart input from the monitoring unit 54, the discomfort occurrence frequency F calculated based on the time chart, and The set mood state is associated and output to the advice information creation unit 56. Thereafter, the mood determination unit 55 ends this routine.

  When the mood determination unit 55 executes the mood determination process described above, it is possible to grasp the transition state of the subject's mood in units of one day and to improve the overall mood of the subject in units of one day. Badness can be determined as a mood state.

  The advice information creation unit 56 inputs the mood rank time chart, the discomfort occurrence frequency F and the mood state for the time chart from the mood determination unit 55. Also, the advice information creating unit 56 creates advice information from the input mood rank time chart that encourages the return of the time when the subject's mood rank is low, that is, the time when the subject is uncomfortable. For example, in the time chart shown in FIG. 5, the mood rank is very low around 10 am. In this case, the advice information creation unit 56 creates advice information such as “I am feeling worse at around 10 am. By providing such advice information to the subject, the subject is aware of the event that occurred at the uncomfortable time and can reconsider it.

  Further, the advice information creating unit 56 creates advice information that can change the mood in consideration of the preference of the target person when the input mood state is “uncomfortable”. For example, the advice information creation unit 56, “How about spending time or talking with an attentive person”, “How about taking a bath and calming down”, “How about taking a walk, exercising, etc.” , Etc., advice information that encourages daily living behavior can be created.

  Further, the advice information creation unit 56 compares the mood rank transition represented in the input time chart with an average transition pattern (average transition pattern) for the target person, and advice information based on the comparison result. Can be created. Specifically, the advice information creation unit 56 extracts, as a singular point, a portion where the mood rank transition represented in the input time chart shows a transition different from the average transition pattern. Then, advice information that prompts regression regarding the occurrence time of the extracted singular point is created. For example, when the change of the mood rank shown in the time chart of the mood rank at about 14:00 is different from the change of the mood rank represented by the average change pattern, the advice information creation unit 56 reads “ "There was a change in the mood different from usual. Did something happen?" By providing such advice information to the subject, the subject is aware of an unusual event that occurred at the extracted time and can reconsider it. The average transition pattern can be read from a transition pattern learning unit 58 described later.

  The advice information creating unit 56 also creates the advice information, the time chart of the mood rank used to create the advice information, the discomfort occurrence frequency F of the time chart, and the mood determined from the time chart. The state is associated and output to the data storage unit 57. The data storage unit 57 stores and stores these data. Each time the advice information creation unit 56 outputs these data, the data storage unit 57 stores and stores these data, so that one subject can be stored for several days, weeks, months, or numbers. Yearly mood information (time chart, frequency of unpleasantness, mood state, advice information) is accumulated in the data storage unit 57.

  The transition pattern learning unit 58 learns the average transition pattern described above. Specifically, the transition pattern learning unit 58 learns an average transition pattern based on a mood rank time chart for a plurality of days for the subject stored in the data storage unit 57. In this case, the transition pattern learning unit 58 averages the mood ranks at the same time represented in all the time charts for the same target person stored in the data storage unit 57, so that the mood rank at that time is calculated. The average value is calculated. By calculating such an average value for all times, an average transition pattern is obtained. The transition pattern learning unit 58 may periodically learn the average transition pattern, or may learn the average transition pattern every time the time chart is accumulated in the data storage unit 57. The learned average transition pattern is read by the advice information creating unit 56 as described above.

  The information providing unit 59 executes information providing processing. FIG. 7 is a flowchart showing a flow of an information provision processing routine executed by the information provision unit 59. This routine is repeatedly executed every predetermined short time. When this routine is activated, the information providing unit 59 first determines whether or not a data inquiry signal has been received in S401 of FIG. Here, application software for receiving information from the mood information providing system 1 according to the present embodiment is installed in the external mobile device 4. The subject activates the application software when he / she wants to browse mood information. Then, by operating the external mobile device 4 in accordance with a command instructed by the activated application software, a data inquiry signal is output from the external mobile device 4. The output data inquiry signal is received by the information providing unit 59 of the server 5 via the repeater 3.

  When the information providing unit 59 determines in S401 that the data inquiry signal has not been received (S401: No), the routine is terminated. On the other hand, when it is determined in S401 that the data inquiry signal has been received (S401: Yes), the information providing unit 59 proceeds to S402 and transmits a password request signal. The transmitted password request signal is received by the external mobile device 4 via the repeater 3. As a result, a screen prompting the input of a password is displayed on the display screen 41 of the external mobile device 4. The subject inputs a password on the display screen 41. The input password is transmitted to the information providing unit 59.

  Next, the information providing unit 59 determines whether a password has been received (S403). If the password has not been received (S403: No), the process waits until the password is received. On the other hand, when a password is received (S403: Yes). The information providing unit 59 advances the processing to S404 and determines whether or not the received password is appropriate. If the password is not appropriate (S404: No), a rejection signal indicating that the password is not appropriate is transmitted to the external mobile device 4 via the relay 3 (S406), and then the process returns to S402. As a result, a description such as “The password is incorrect” is displayed on the display screen 41 of the external mobile device 4 and a screen prompting the user to input the password again.

  On the other hand, when the received password is appropriate (S404: Yes), the information providing unit 59 cancels the authentication (S405). As described above, the information providing unit 59 has an authentication function. When the authentication is canceled, the information providing unit 59 advances the process to S407 and transmits an inquiry content selection signal to the external mobile device 4 via the repeater 3. As a result, a screen on which the inquiry content requested by the subject can be selected is displayed on the display screen 41 of the external mobile device 4. Examples of the inquiry content that can be selected include “browsing mood information for one day yesterday” and “browsing mood information for the past several days”.

  Subsequently, the information providing unit 59 determines whether or not a signal representing the inquiry content has been received from the external mobile device 4 (S408). If a signal representing the inquiry content has not been received, wait until it is received. On the other hand, if a signal representing the inquiry content is received, the process proceeds to S409. In S409, the information providing unit 59 collects and processes necessary mood information including at least the mood state (uncomfortable or comfortable) determined by the mood determination unit 55 according to the received inquiry content. Next, the collected mood information is transmitted (S410). The transmitted mood information is displayed on the display screen 41 of the external mobile device 4 via the repeater 3. Thereby, a subject person can browse desired mood information. In this way, the subject is provided with mood information including the mood state (discomfort, comfort) determined by the mood determination unit 55.

  In this case, when the inquiry content received by the information providing unit 59 includes the content of browsing mood data for one day, the information providing unit 59 stores the mood information (time chart) stored in the data storage unit 57. The mood information on the corresponding date is read out from the unpleasant occurrence frequency F, mood state, advice information) and transmitted. Thereby, the mood information about the corresponding day is displayed on the external mobile device 4. In addition, when the received inquiry content includes the content of browsing mood information for several days at a time, the information providing unit 59 determines the number of days corresponding to the mood information stored in the data storage unit 57. The mood information is read out, and a time chart is created by combining the time charts of the mood ranks included in the read mood information. And the signal showing the created time chart is transmitted. Thereby, a time chart in which mood data for several days are collectively displayed on the external mobile device 4 is displayed.

  The mood information transmitted in S410 can include inquiry information. The inquiry information is information including contents for inquiring about what has happened when the subject's mood change state is different from normal. As the inquiry information, for example, a content such as “A change in mood that is different from usual at 16:00 has been observed.

  Therefore, when the inquiry information is transmitted together in S410, the information providing unit 59 advances the process to S411, and determines whether an answer to the inquiry information is input. When an answer to the inquiry information is input (S411: Yes), the information providing unit 59 outputs the answer to the data storage unit 57 in association with the mood information related to the answer. Thereby, the data storage part 57 can memorize | store the reply of inquiry information. Thereafter, the information providing unit 59 advances the process to S413. In addition, when the inquiry information is not transmitted in S410, the processing of S411 and S412 can be omitted.

  If it is determined in S411 that the answer to the inquiry information has not been input (S411: No), the information providing unit 59 skips the process of S412 and advances the process to S413. In S413, the information providing unit 59 determines whether or not an additional inquiry request signal has been transmitted. This additional inquiry request signal can be transmitted from the external mobile device 4 by the subject. When the additional inquiry request signal is transmitted (S413: Yes), the information providing unit 59 returns the process to S407 and repeats the processes of S407 to S413. On the other hand, if the additional inquiry request signal is not transmitted even after a predetermined time has elapsed (S413: No), the information providing unit 59 ends this routine.

  As described above, the server 5 as the mood determination device provided in the mood information providing system 1 according to the present embodiment includes the biological signal acquisition unit 51 that acquires a biological signal that affects the mood of the subject, and the biological signal acquisition. Information representing the mood value calculated by the mood value calculation unit 52 during the day and the mood value calculation unit 52 that calculates the mood value indexed by the subject's mood based on the biological signal acquired by the unit 51. A monitoring unit 54 that creates a mood value time chart by monitoring a certain mood rank in association with time, and a mood determination unit that determines the mood of the subject in units of one day based on the mood value time chart 55.

  According to the mood determination device (server 5) according to the present embodiment, whether the subject's mood is good on a daily basis based on the mood rank transition of the subject's mood value calculated during the day. Can judge comprehensively whether it is bad.

  In addition, the mood determination unit 55 calculates an unpleasant occurrence frequency calculation process that calculates an unpleasant occurrence frequency F that is a frequency at which the transition of the mood rank shown in the mood rank time chart falls below the threshold rank (mood rank 4). S302) and determination processing (S303, S304, S304) for determining the mood of the subject in units of one day based on whether or not the unpleasant occurrence frequency F is equal to or higher than a predetermined threshold frequency Fth. Run. By executing such processing, it is possible to comprehensively determine the mood of the subject in units of one day based on the number of times (frequency) that the subject felt uncomfortable during the day.

  The mood determination device (server 5) includes an advice information creation unit 56. The advice information creation unit 56 creates advice information that prompts the return of the time when the subject is uncomfortable from the mood rank time chart. By providing the above-mentioned advice information created by the advice information creating unit 56 to the target person, it is possible to return to the time when the target person is uncomfortable and to be aware of the event that occurred at that time. The subject can be rethought.

  The mood determination device (server 5) includes a data storage unit 57 and a transition pattern learning unit 58. The data storage part 57 memorize | stores the time chart of the mood rank for 1 day of a subject about several days. The transition pattern learning unit 58 also learns an average transition pattern, which is an average mood value information transition pattern, based on a mood rank time chart for a plurality of days stored in the data storage unit 57. Then, the advice information creation unit 56 extracts, as a singular point, a portion where the mood rank transition (mood value information transition) shown in the input mood rank time chart shows a transition different from the average transition pattern. The advice information that prompts the regression regarding the occurrence time of the singular point is created. By providing such advice information to the subject, it is possible to promote awareness of the event that occurred at that time, and to make the subject reconsider the event.

  The mood determination device (server 5) includes an information providing unit 59. The information providing unit 59 has an authentication function, and provides mood information including a determination result (a mood state) by the mood determination unit 55 when the authentication is canceled. The authentication function of the information providing unit 59 can prevent information related to the subject's mood from being leaked to others. In addition, when the authentication is canceled, the information providing unit 59 provides the subject with the mood determination result, so that the subject can be informed of the overall mood of the day.

(Modification 1)
Next, a modified example of the above-described embodiment will be described. This modified example is different from the above-described embodiment only in the mood determination process by the mood determining unit 55, and the other parts are the same as the above-described embodiment. Therefore, only the mood determination process by the mood determination unit 55 will be described, and the description of the other parts will be omitted as the above embodiment.

  FIG. 8 is a flowchart showing the flow of a mood determination processing routine executed by the mood determination unit 55 according to this modification. When this routine is started, the mood determination unit 55 first determines whether or not a mood rank time chart has been input from the monitoring unit 54 in S501 of FIG. When the mood rank time chart is not input (S501: No), the mood determination unit 55 ends this routine. On the other hand, when the mood rank time chart is input (S501: Yes), the mood determination unit 55 advances the process to S502.

  In S502, the mood determination unit 55 calculates the unpleasant time ratio RT from the input mood rank time chart. The unpleasant time ratio RT is a ratio of the unpleasant time T0 to the reference time t0. Here, the “discomfort time” is a region where the transition of the mood rank shown in the input mood rank time chart is below the predetermined discomfort zone threshold rank in the uncomfortable direction (that is, the mood rank decreases). That is, it is the time to transit the discomfort zone. In addition, the “reference time” refers to a mood rank in which the mood rank transition represented in the input mood rank time chart is higher in a comfortable direction (that is, in a direction in which the mood rank becomes larger) than the threshold rank in the unpleasant zone in advance. The time is below the standard rank. Therefore, the uncomfortable time ratio RT is less than the reference rank higher in the comfortable direction than the threshold rank in the uncomfortable direction when the mood rank transition represented in the time chart of the mood rank falls below the threshold rank in the uncomfortable zone in the uncomfortable direction. It is a percentage of time. The process of S502 corresponds to the unpleasant time ratio calculation process of the present invention.

The unpleasant time ratio RT when the mood rank time chart input to the mood determination unit 55 is as shown in FIG. 9 will be described. In FIG. 9, the threshold rank of the discomfort zone is a mood rank 4 representing a “slightly uncomfortable” mood. In this case, the discomfort zone is represented by an area below the mood rank 4. Of the mood rank transitions shown in the mood rank time chart shown in FIG. 9, the time T0 (discomfort time) below the mood rank 4 is represented by T1 + T2 + T3 + T4 + T5 in FIG. In FIG. 9, the reference rank is a mood rank 7. In this case, the time t0 (reference time) when the mood rank represented by the mood rank time chart falls below the mood rank 7 (reference rank) is represented by t1 + t2 + t3 + t4 in FIG. Therefore, the unpleasant time ratio RT is
RT = T0 / to = (T1 + T2 + T3 + T4 + 5) / (t1 + t2 + t3 + t4)
As required.

  After calculating the unpleasant time ratio RT, the mood determination unit 55 advances the process to S503. In S503, it is determined whether or not the unpleasant time ratio RT obtained in S502 is equal to or greater than the threshold time ratio RTth. The threshold time ratio RTth is set in advance as a ratio with which it is possible to determine that the subject's mood is uncomfortable when the uncomfortable time ratio RT is greater than that.

  If the unpleasant time ratio RT is equal to or greater than the threshold time ratio RTth (S503: Yes), the mood determination unit 55 sets the mood state to “uncomfortable” (S504). On the other hand, when the unpleasant time ratio RT is less than the threshold time ratio RTth (S503: No), the mood determination unit 55 sets the mood state to “comfortable” (S505). The mood determination unit 55 sets the mood state to “uncomfortable” or “comfortable” in S504 or S505, thereby determining the mood of the subject in units of one day. The processes of S503, S504, and S505 correspond to the determination process of the present invention.

  After the mood determination unit 55 sets the mood state in S504 or S505, the process proceeds to S506, the time chart input from the monitoring unit 54, the uncomfortable time ratio RT calculated based on the time chart, and the set mood The state is associated and output to the advice information creation unit 56. Thereafter, the mood determination unit 55 ends this routine.

  As described above, according to the first modification, based on the time during which the subject feels uncomfortable in the day (or the ratio of the time when the subject feels uncomfortable), the subject's daily mood is comprehensively determined. Can be determined.

(Modification 2)
Next, other modified examples of the above-described embodiment will be described. This modified example is different from the above-described embodiment and the modified example 1 only in the mood determination process by the mood determining unit 55, and other parts are the above-described implementations. The form is the same. Therefore, only the mood determination process by the mood determination unit 55 will be described, and the description of the other parts will be omitted as the above embodiment.

  FIG. 10 is a flowchart showing the flow of a mood determination process routine executed by the mood determination unit 55 according to this modification. When this routine is activated, the mood determination unit 55 first determines whether or not a mood rank time chart is input from the monitoring unit 54 in S601 of FIG. When the mood rank time chart is not input (S601: No), the mood determination unit 55 ends this routine. On the other hand, when the mood rank time chart is input (S601: Yes), the mood determination unit 55 advances the process to S602.

  In S602, the mood determination unit 55 obtains the uncomfortable area ratio RS from the input mood rank time chart. The unpleasant area ratio RS is a ratio of the unpleasant area S0 to the reference area s0. Here, the “discomfort area” is an area in which the transition of the mood rank shown in the input mood rank time chart changes in the above-described discomfort zone. Furthermore, “discomfort area” means the difference between the mood rank and the threshold rank in the time when the transition of the mood rank shown in the input mood rank time chart falls below the threshold rank of the discomfort zone (discomfort time). This is the absolute time integral value. In addition, the “reference area” is an area in which the transition of the mood rank shown in the input mood rank time chart is lower than a reference rank that is predetermined as a mood rank higher in the comfortable direction than the threshold rank of the uncomfortable zone. It is. Furthermore, the “reference area” is the absolute value of the difference between the mood rank and the reference rank at the time when the mood rank transition shown in the input mood rank time chart is below the reference rank (reference time). Time integral value. Therefore, the uncomfortable area ratio RS is lower than the reference rank in which the transition of the mood rank shown in the time chart of the mood rank is lower than the threshold rank of the uncomfortable zone in the uncomfortable direction is higher in the comfort direction than the threshold rank in the uncomfortable direction. It is the ratio to the area. The process of S602 corresponds to the uncomfortable area ratio calculation process of the present invention.

  FIG. 11A is a diagram showing an uncomfortable area S0 in the mood rank time chart input to the mood determination unit 55. FIG. In FIG. 11A, the threshold rank of the discomfort zone is mood rank 4. In this case, the discomfort zone is represented by an area below the mood rank 4. In the transition of the mood rank represented by the time chart shown in FIG. 11A, the area below the mood rank 4, that is, the unpleasant area S0, is the five regions (S1, S2, S3, S4, S4) indicated by the oblique lines in FIG. 11A. It is the sum. That is, the uncomfortable area S0 is S1 + S2 + S3 + S4 + S5.

  FIG. 11B is a diagram showing the reference area s 0 in the mood rank time chart input to the mood determination unit 55. In FIG. 11B, the reference rank is 7. In this case, in the transition of the mood rank shown in the time chart shown in FIG. 11B, the area below the reference rank 7, that is, the reference area s0, is represented by the four regions (s1, s2, s3, This is the sum of s4). That is, the reference area s0 is s1 + s2 + s3 + s4.

Therefore, the uncomfortable area ratio RS is
RS = S0 / s0 = (S1 + S2 + S3 + S4 + S5) / (s1 + s2 + s3 + s4)
As required.

  After calculating the unpleasant area ratio RS, the mood determination unit 55 advances the process to S603. In S603, it is determined whether or not the uncomfortable area ratio RS obtained in S602 is equal to or greater than the threshold area ratio RSth. The threshold area ratio RSth is set in advance as a ratio with which it is possible to determine that the subject's mood is uncomfortable when viewed as a whole when the unpleasant area ratio RS is greater than that.

  When the unpleasant area ratio RS is equal to or greater than the threshold area ratio RSth (S603: Yes), the mood determination unit 55 sets the mood state to “uncomfortable” (S604). On the other hand, when the unpleasant area ratio RS is less than the threshold area ratio RSth (S603: No), the mood determination unit 55 sets the mood state to “comfortable” (S605). By setting the mood state to “uncomfortable” or “comfortable” in S604 or S605, the mood of the subject in units of one day is determined. The processes of S603, S604, and S605 correspond to the determination process of the present invention.

  After the mood determination unit 55 sets the mood state in S604 or S605, the process proceeds to S606, the time chart input from the monitoring unit 54, the uncomfortable area ratio RS calculated based on the time chart, and the set mood The state is associated and output to the advice information creation unit 56. Thereafter, the mood determination unit 55 ends this routine.

  According to this modification, it is possible to comprehensively determine the mood of the subject in units of one day based on the time during which the subject feels uncomfortable and the degree of discomfort. it can.

  As mentioned above, although embodiment of this invention and its modification were demonstrated, this invention is not limited to the said embodiment. For example, in the above embodiment, an example is shown in which mood information is provided in response to a request from the subject. However, mood information including the mood state of the previous day is provided to the subject at a fixed time (for example, 7:00 in the morning). It can also be configured. In addition, the biological signal detection sensor 2 used in the above embodiment is used for estimating mood (calculating a mood value). For example, when sleeping, the biological signal detection sensor 2 can also be used as a sleep sensor. In this case, the mood can be estimated at the time of the subject's activity, and the sleep level can also be estimated at the time of going to bed.

  Moreover, in the said embodiment and the modification, although the monitoring part 54 showed the example which acquires a subject's mood value information transition by producing the time chart of a mood rank, by creating the time chart of a mood value The mood value information transition of the target person may be acquired. Further, in the above embodiment and the modified example, the monitoring unit 54 creates a time chart in which the mood rank is discontinuously shown every 10 minutes, but the time chart in which the mood rank is shown continuously. It can also be created.

  Moreover, in the said modification 1, although the example which determines the mood in a day unit based on the ratio with respect to the reference | standard time of a discomfort generation time was shown, the mood in a day unit is determined based on a discomfort generation time. You can also Moreover, in the said modification 2, although the example which determines the mood per day based on the ratio with respect to the reference | standard area of a discomfort generation area was shown, the mood per day is determined based on a discomfort generation area You can also

  Moreover, in the said modification 1 and the modification 2, although the threshold rank was set to 4 and the reference rank was set to 7, the threshold rank and the reference rank were set to arbitrary mood ranks according to the situation. You can also. For example, the reference rank can be set to mood rank 10. Further, in the above-described embodiment and modification, an example is shown in which the mood determination unit 55 determines whether the mood state is “uncomfortable” or “comfortable”. However, by providing two or more determination thresholds, the mood The state can be expressed more finely. Moreover, this invention can also be comprised so that the feeling of a bedridden person may be determined, for example. In this case, a biological signal detection sensor is installed in the subject's bed, and the mood can be determined from the biological signal detected by the biological signal detection sensor. According to this, it is possible to inform a nurse or the like that a bedridden person is uncomfortable due to pressure sores or the like. The mood determination device (server 5) according to the present invention can also be connected to an emergency power source. According to this, even if it is at the time of a power failure, a subject's mood can be determined stably. Moreover, the mood determination apparatus (server 5) which concerns on this invention may have a function which reproduces a subject's favorite music. And when a subject's mood rank is low, you may be comprised so that a favorite music may be reproduced | regenerated automatically. Thus, the present invention can be modified without departing from the gist thereof.
