Hereinafter, a stress reduction plan proposal system according to an embodiment of the present invention will be described. The stress reduction plan proposal system according to the present embodiment proposes a stress reduction plan to prospective participants.
In this embodiment, as an activity (activity) for reducing stress, an activity (non-daily activity) in a place away from the daily activity range of the prospective participant is assumed. For example, for urban residents, activities such as farming experiences in villages, sightseeing, local cuisine, and hot springs are assumed. However, activities that can help reduce the stress of the prospective participants, such as movie appreciation, music appreciation, incense, and theater performances, may be included in the activity. In other words, the activity is used as a term indicating 3R (rest, healing, entertainment) in general for stress reduction.

  In the stress reduction plan proposing system according to the present embodiment, a database for storing the degree of stress reduction expected from the activity experience is prepared. The stress reduction degree is calculated based on the measurement results for each activity in advance, as will be described in detail later. Along with this degree of mitigation, a plan including an activity that is expected to be mitigated (hereinafter referred to as an activity plan) is presented. The activity plan may include an activity not intended to reduce stress, but in the present embodiment, the activity plan includes at least one activity for stress reduction. In addition, in the stress reduction plan proposing system of this embodiment, a plurality of activities are registered in the database in association with the degree of reduction, and a combination of activities is selected so that the stress of the prospective participant is expected to be reduced. An activity plan including the selected activity can be presented.

  FIG. 1 is a diagram showing an overall configuration example of a stress reduction plan proposal system 1 according to the present embodiment. The stress reduction plan proposal system 1 according to the present embodiment includes a plan proposal device 20. The plan proposal device 20 is connected to the user terminal 10 and the measurement device 30 via the network 40 so as to be able to communicate with each other.

  The connection method between the plan proposal device 20 and each of the user terminal 10 and the measurement device 30 may be wired or wireless. The plan proposal device 20 may be configured to be accessible to the weather database 21 via a wired or wireless line. The weather database 21 is a database of, for example, the Japan Meteorological Agency or a weather information provider, which records actual measured values and weather forecast values of the weather at or near the place where the activity is performed.

  FIG. 2 is a diagram illustrating a configuration example of the measurement apparatus 30. The measuring device 30 measures the biological data of the subject and transmits it to the plan proposing device 20. In this embodiment, the measuring device 30 is assumed to be a heart rate meter (pulse meter) that measures a heart rate as biological data. However, the measuring device 30 may measure other biological data such as body surface temperature, blood pressure, sweating, and breathing. Further, the measurement device 30 may include an acceleration sensor, for example, to detect the movement of the measurement device 30 and to estimate the body movement of the subject from the movement.

  It is assumed that the measuring device 30 is continuously worn by the subject from before the start of the activity to after the end of the activity. Therefore, it is preferable that the measuring apparatus 30 is a wearable device that can be attached to or wrapped around the subject's earlobe, chest, wrist, abdomen, or the like. However, the measurement apparatus 30 may be configured to be a device that is carried with the subject, such as a smartphone, and to receive information from a biological sensor such as a heart rate monitor (pulse meter).

  Here, the test subject is a concept different from the participant in the activity, and as a premise of the proposal of the stress reduction plan according to the present embodiment, the test subject says a person who is a target of stress measurement for collecting sample data. To do. In the present embodiment, it is only necessary to obtain sample data before and after the activity of a plurality of subjects for each activity. The subject may be a participant in the activity.

  However, stress measurement may also be performed for participants in each activity before, during, and after the activity. Further, by incorporating the measurement results of the participants into the measurement result database 222 of the plan proposing device 20, it is expected that the reliability of the stress reduction effect and the reliability of the proposal contents will be improved.

  The measurement apparatus 30 is a wearable device, for example, including a measurement unit 301, a time measurement unit 302, and a transmission unit 303. The measuring unit 301 measures biological data such as a heartbeat, for example, and the time measuring unit 302 adds a measurement time to the measured biological data. Such measurement data is output from the transmission unit 303. Measurement data from the measurement device 30 is received by the plan proposal device 20 and stored as a measurement result in the measurement result database 222 (see FIG. 7).

  The measuring device 30 may include positioning means such as a global positioning system (GPS). In that case, the measuring apparatus 30 can further add information on the measurement location (for example, longitude and latitude, address, facility name, etc.) to the measurement data.

  Further, the measuring device 30 may have means for acquiring or measuring weather data such as weather, temperature, atmospheric pressure, and humidity. In that case, the measuring device 30 can add weather information at the measurement location to the measurement data. However, the weather information may be added to the measurement results in the measurement result database 222 by referring to the weather database 21 on the plan proposal device 20 side.

  Further, the measuring device 30 may have an output function such as a display screen or a speaker. For example, when an abnormality occurs such that the measurement result greatly exceeds the normal range, the abnormality can be notified to the subject (participant) by generating a warning sound or causing a pop-up to appear on the screen. In addition, when using the measuring apparatus 30 in the state connected to the user terminal 10 which is a portable terminal, it is good also as the user terminal 10 alert | reporting abnormality.

  The user terminal 10 is a computer used by the user, and may include a plurality of user terminals. Here, the user includes, for example, a person in charge of a travel company, a welfare officer of a company to which the prospective participant belongs, in addition to a person who plans to participate in various activities (participant). The user terminal 10 is, for example, a smartphone, a tablet computer, a mobile phone terminal, a portable (notebook) personal computer, an installation (desktop) personal computer, or the like.

  In the present embodiment, it is assumed that the user makes a proposal request to the plan proposal apparatus 20 via the user terminal 10, and the plan proposal apparatus 20 executes a predetermined process and returns a processing result (proposition of activity plan). ing. However, the present invention is not limited to such a processing method, and for example, necessary processing may be executed on the user terminal 10 side.

  The plan proposal device 20 is a computer that executes a predetermined process and transmits a processing result to the user terminal 10 when a proposal request is received from the user terminal 10. The plan proposal device 20 may be realized by, for example, one or a plurality of personal computers or workstations.

  FIG. 3 is a diagram illustrating a hardware configuration example of a computer used as the user terminal 10 and the plan proposal device 20. The user terminal 10 and the plan proposal device 20 include a CPU 201, a memory 202, a storage device 203, a communication interface 204, an input device 205, and an output device 206.

  The storage device 203 is, for example, a hard disk drive, a solid state drive, or a flash memory that stores various data and programs. The communication interface 204 is an interface for connecting to the communication network 40. For example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone line network, and a wireless communication device for performing wireless communication A USB (Universal Serial Bus) connector for serial communication, an RS232C connector, or the like. The input device 205 is, for example, a keyboard, a mouse, a touch panel, a button, or a microphone that inputs data. The output device 206 is, for example, a display, a printer, or a speaker that outputs data.

  FIG. 4 is a diagram illustrating a software configuration example of the plan proposal device 20. The plan proposal device 20 includes a reception unit 211, a stress index calculation unit 212, a fluctuation calculation unit 213, an evaluation unit 214, a transmission unit 215, a user database 221, a measurement result database 222, and a mitigation effect database 223.

The reception unit 211, the stress index calculation unit 212, the fluctuation calculation unit 213, the evaluation unit 214, and the transmission unit 215 read the program stored in the storage device 203 into the memory 202 and execute it by the CPU 201 included in the plan proposal device 20. Is realized.
In addition, the user database 221, the measurement result database 222, and the reduction effect database 223 are realized as part of a storage area provided by the memory 202 and the storage device 203.

  The receiving unit 211 receives a proposal request from the user terminal 10 and receives a measurement result from the measurement device 30. Here, the proposal request is an instruction for requesting the plan proposal device 20 to propose an activity plan, and includes, for example, information on a prospective participant and a schedule (for example, the first and last dates of the itinerary). As the measurement result, heart rate data is assumed here, but other biological data may be used. Details of the measurement result will be described in relation to the measurement result database 222.

  The stress index calculation unit 212 calculates a stress index based on the measurement result. In this embodiment, an LF / HF value is assumed as the stress index, but another index such as an RR interval variation coefficient (CVRR) may be used. Here, the LF / HF value is an index indicating the degree of sympathetic nerve activity obtained by spectrum analysis of heartbeat data, and details will be described later.

  The fluctuation calculation unit 213 calculates the degree of fluctuation using the stress index. Specifically, the fluctuation calculation unit 213 calculates the degree of fluctuation of the stress index before and after the experience for each of the plurality of subjects for each activity, and totalizes the degree of fluctuation and records it in the reduction effect database 223. . In the present embodiment, the degree of variation of the stress index is given as a relative variation ratio of the stress index before and after the experience of the activity (see FIG. 8).

  The evaluation unit 214 sets, as an activity plan (sometimes simply referred to as a “plan”), a combination of activities that is expected to reduce the stress of the prospective participant among a plurality of activities registered in the reduction effect database 223. Select. In other words, it can be said that the evaluation unit 214 evaluates a plurality of activities using the stress reduction effect on the prospective participants as a main criterion. The evaluation unit 214 can select a predetermined number of activities in descending order of, for example, the degree of stress reduction. Furthermore, when there are a plurality of prospective participants, the evaluation unit 214 may evaluate a plurality of activities using, for example, an average stress reduction effect converted for each prospective participant as a main criterion. At the time of the evaluation, as will be described later, the evaluation unit 214 corrects the stress reduction effect based on additional indicators such as weather, season, and attribute of the prospective participant, and based on the corrected stress reduction effect. You can also formulate an activity plan.

  In the present embodiment, the activity plan includes at least two activities, but may include only one activity. The selected activity plan may be one set or a plurality of sets.

  The evaluation unit 214 may select a combination of activities in accordance with the weather conditions expected in the participation schedule for the activities of the prospective participants. Here, the weather conditions are not limited to weather such as sunny, cloudy, rainy, etc. at the place where the corresponding activity is performed, but temperature, atmospheric pressure, wind speed, humidity, precipitation, solar radiation, sunshine duration, snowfall, It may be any weather element such as the amount of snow.

For example, outdoor work on rainy days, cold days, windy days, hot and humid days is not comfortable. Outdoor work is not appropriate as an activity on such schedules where the weather is expected.
Further, it is known that when the pressure fluctuation is large, the number of people who develop headaches or complain of poor physical condition tends to increase. On schedules where such weather is expected, you may prefer to be quiet indoors, for example, hot springs, meals, and appreciation.
Therefore, in the stress reduction plan proposing system 1 of the present embodiment, the actually measured stress reduction degrees are tabulated for each weather condition, and the stress reduction degrees according to the weather conditions are objectively evaluated.

  The evaluation unit 214 may select a combination of activities according to the season to which the participation schedule for the activities of the prospective participants belongs. For example, winter water work can be stressful, but summer water work can be rather cool and happy. Therefore, activities such as water work are not appropriate when the day is scheduled in winter. As described above, the appropriate / inappropriate evaluation may change depending on the season. Therefore, in the stress reduction plan proposing system 1 of the present embodiment, the actually measured stress reduction degree is aggregated for each season, and the stress corresponding to the season is calculated. Objectively evaluate the degree of mitigation.

  Alternatively, the evaluation unit 214 may select a combination of activities according to the attribute of the prospective participant. Here, the attribute of the prospective participant is a geographic, demographic, or psychographic characteristic of the prospective participant, for example, sex, age group, hobby, things that are not good. For example, it is not appropriate to propose farming work to prospective participants who are not good at insects. On the other hand, the stress reduction effect due to the farm work experience is higher than the discomfort with insects, and the stress reduction effect as a whole may be possible. Therefore, in the stress reduction plan proposing system 1 of this embodiment, as will be described later, the actually measured stress reduction degree is aggregated for each subject attribute, and the stress reduction degree according to the season is objectively evaluated. Yes. As a premise that the evaluation unit 214 uses such an attribute, the stress reduction effect of the attribute needs to be recorded in the reduction effect database 223.

  Further, the evaluation unit 214 may select a combination of activities according to the number of days of participation of the prospective participant. For example, when the number of participating days is short, a combination of activities performed in a relatively close place (not requiring much travel time) is appropriate. However, if the number of activities is increased too much, the participants will be tired and will not be able to reduce stress. Therefore, an upper limit may be set for the number of activities that can be participated in a day.

  Details of the processing by the evaluation unit 214 will be described later.

  The transmission unit 215 (corresponding to the “output unit” of the present invention) outputs information for presenting a plan including the activity (hereinafter referred to as presentation information) along with the degree of activity reduction. In the present embodiment, it is assumed that the presentation information is screen information described in HTML (HyperText Markup Language). In the present embodiment, the transmission unit 215 transmits screen information to the user terminal 10. Note that the presentation information is not limited to screen information in the HTML format, and the output destination may be an output device 206 such as a printer or a display.

  FIG. 5 is a diagram illustrating a configuration example of screen information displayed on the output device 206. As illustrated, screen information is displayed on a screen 207 of the output device 206 (display). In the present embodiment, the itinerary, the destination, and the plan are displayed on the screen 207. As described above, the plan includes activities, and the activities are displayed in association with the degree of stress reduction. Also, when the presentation information is transmitted to the printer as the output device 20, the same information as the screen information in FIG. 5 is printed. Such presentation information allows the user to easily grasp the plan including the activity and the corresponding stress reduction degree.

  FIG. 6 is a diagram illustrating a configuration example of the user database 221. The user database 221 is a database including information related to users. In the present embodiment, the user database 221 includes, for example, ID, name, sex, age group, hobby, etc. for each user. In addition, the user database 221 may include information on things that are not good (for example, insects, disliked foods, etc.). Such user information can be used for activity evaluation.

  FIG. 7 is a diagram illustrating a configuration example of the measurement result database 222. The measurement result database 222 stores the measurement results of the measurement device 30 received by the plan proposal device 20. In the present embodiment, for example, the ID of the subject (participant), the measurement time, the measurement location, the content of the activity, the weather condition of the measurement location, and the measurement value. In the figure, the measured value is displayed in a graph, but it does not have to be in such a display format. As described above, the measurement is performed at least before and after the work.

  The measurement result database 222 only needs to store the measurement results for the subject. However, the measurement result database 222 may additionally store the measurement results of the participants who participated in the subsequent activities. In this case, when the measurement result of the participant is obtained, the sample data recorded in the measurement result database 222 is increased, the reliability of the data is improved, and the reliability of the proposal content is increased.

  FIG. 8 is a diagram illustrating a configuration example of the reduction effect database 223. The reduction effect database 223 is an example of a database in which a plurality of activities are associated with the degree of stress reduction of the participant in the corresponding activity (calculation result of the fluctuation calculation unit 213). In the present embodiment, the mitigation effect database 223 stores the degree of stress reduction expected by the activity in association with the season and weather conditions for each activity.

  In the present embodiment, as shown in FIG. 8, each activity (activity), season, weather, and stress reduction degree are associated in the reduction effect database 223. However, the present invention is not limited to this, for example, any combination of other weather information such as temperature, atmospheric pressure, and humidity, and geographic, demographic, and psychographic attributes such as sex, hobbies, and things that are not good And the degree of stress reduction may be shown. By including such information in the mitigation effect database 223, it becomes possible to propose a detailed activity plan according to the weather forecast on the day of the activity and the attributes of the prospective participants, and an improvement in user satisfaction can be expected.

  In FIG. 8, the stress reduction effect of each activity under a specific season and weather is displayed as a representative value of the relative reduction ratio. For example, the representative value of the stress reduction ratio based on a plurality of measurement results for farm work on a sunny day of spring is 6%. Here, the representative value is an average value, median value, mode value, or the like of a plurality of stress reduction ratios. A representative value that can be expected to have the highest reliability may be appropriately selected.

  Hereinafter, main processes in the stress reduction plan proposal system 1 of the present embodiment will be described. These processes include a process for proposing an appropriate combination of activities in response to a proposal request from the user terminal 10 (S21 to S23; see FIG. 10), and a stress reduction effect is measured for each activity as a premise of the proposal. The processing is roughly divided into the processing (S11 to S17; see FIG. 9), and these processing will be described in time series. In addition, although it assumes that these processes are mainly performed in the plan proposal apparatus 20, you may perform in the user terminal 10, for example.

  FIG. 9 is a diagram showing a flow of processing for measuring the degree of stress reduction from the measurement result. In this embodiment, since the heart rate is adopted as the biological data related to the measurement, a procedure for calculating the degree of stress reduction from the heart rate data will be described.

  When the plan proposal device 20 receives measurement data (heart rate data) from the measurement device 30 (S11), the stress index calculation unit 212 calculates heart rate variability data (S12). The heart rate variability data is obtained, for example, by taking time series data of an interval (RR interval: RRI) between the R wave peak of the corresponding heart rate waveform and the R wave peak of the next heart rate waveform. It should be noted that a well-known method can be used for acquiring heart rate variability data, and detailed description thereof is omitted here.

  Next, the stress index calculation unit 212 converts the heart rate variability data into the frequency domain (S13), and integrates (integrates) the converted heart rate variability data (intensity) over a predetermined frequency band to obtain a low frequency (LF) value. Then, a high frequency (HF) value is calculated (S14). For example, the integration range for obtaining the LF value is 0.05 to 0.20 Hz, and the integration range for obtaining the HF value is 0.20 to 0.35 Hz. Note that this integration range can be changed by setting.

  Then, the stress index calculation unit 212 calculates an LF / HF value that is a ratio of these using the LF value and the HF value (S15). The LF / HF value is calculated for each of the activities before and after the experience. As described above, the LF / HF value is one of the indices indicating the degree of sympathetic nerve activity. For example, when the LF / HF value is 5.0 or more, a state in which a very strong stress is applied. Can be evaluated. Therefore, in this embodiment, LF / HF value = 5.0 is set as a reference value.

  Further, the fluctuation calculating unit 213 calculates the degree of fluctuation of the LF / HF value using the LF / HF value before and after the experience of the activity (S16). Here, the variation degree of the LF / HF value is a relative variation ratio (%) obtained by dividing the difference between the LF / HF values before and after the activity by the reference value.

Then, the fluctuation calculation unit 213 stores the degree of fluctuation of the LF / HF value in the measurement result database 222. Here, the fluctuation calculation unit 213 receives an input of the name of the activity (contents of “activity” in the measurement result database 222), receives an input of a place where the activity is performed, or position information (latitude such as GPS) The location is identified based on the longitude, etc., weather information corresponding to the location is acquired from the weather database 21, the current time (measurement time), the location, the name, the weather information, and the LF / HF value. Can be registered in the measurement result database 222 in association with each other.
Next, the fluctuation calculation unit 213 calculates a representative value of the measurement value corresponding to the name registered in the measurement result database 222. Here, the fluctuation calculation unit 213 calculates a representative value for each season included in the season at the present time (measurement time) and the weather information. The fluctuation calculation unit 213 stores the calculated representative value in the reduction effect database 223 in association with the name, season, and weather information as the reduction degree (S17).

  In this way, the plan proposal device 20 executes a series of stress reduction effect calculation processes for each activity. And the plan proposal apparatus 20 will repeat the process of S11-S17, if new measurement data are received.

Next, plan proposal processing will be described. This processing is mainly performed in the evaluation unit 214 and the transmission unit 215.
FIG. 10 is a diagram showing a flow of processing for selecting a combination of activities considered to be appropriate for reducing the stress of a prospective participant.

  With the operation of the user terminal 10 by the user, the plan proposal device 20 receives a proposal request from the user terminal 10 in the receiving unit 201 (S21). This proposal request may include the number of prospective participants, the first and last days of the itinerary, the attributes of the prospective participants, and the like.

  The evaluation unit 214 selects a combination of activities considered appropriate for reducing the stress of the prospective participant from a plurality of activities registered in the reduction effect database 223 (S22). As for the activity selection method, for example, the evaluation unit 214 may select a predetermined number in descending order of the degree of reduction, or may use various optimization methods such as regression analysis, artificial intelligence (AI), and machine learning. May be used. In addition, one or more activities included in the plan are recorded in association with the plan, and the evaluation unit 214 calculates the total reduction effect corresponding to the activities included in the plan for each plan, and reduces the reduction. A plan may be selected according to the total effect.

  In the present embodiment, it is assumed that the evaluation unit 214 selects a combination of activities suitable for time and weather and activities suitable for the attributes of prospective participants based on information included in the proposal request. One criterion for evaluation here is that an activity having a relatively large stress reduction effect is preferentially selected.

  For example, based on the itinerary included in the proposal request, the evaluation unit 214 evaluates the activity suitable for the season in which the travel is performed relatively large (or relatively small the activity inappropriate for the season). Is possible. Further, the evaluation unit 214 can refer to the weather forecast during the itinerary from the weather database 21 and evaluate the activity suitable for the predicted weather relatively large. In the case of a relatively large trip such as an employee trip or a training trip, for example, the evaluation unit 214 takes into account an acceptable facility, for example, an activity in a place where the distance from the facility is within an allowable range. Can be preferentially selected. Furthermore, when the proposal request includes attributes of the prospective participant, the evaluation unit 214 evaluates activities corresponding to these attributes relatively large, so that detailed activities according to the preference of the prospective participant can be obtained. Can be selected. The selection of such an appropriate activity increases the participant's stress reduction effect and improves the participant's satisfaction.

  The proposal to the user may be a set of activity plans or a plurality of activity plans. In the case of proposing a plurality of sets of activity plans, the user can select a more preferable plan from among a plurality of plans, so that improvement in user satisfaction can be expected.

And the plan proposal apparatus 20 transmits the combination of the selected activity to the user terminal 10 via the transmission part 215 (S23). Thus, a series of activity plan proposal processing is completed.
The activity plan proposal process is repeated each time the plan proposal device 20 receives a proposal request from the user terminal 10.

As described above, according to the stress reduction plan proposing system 1 (plan proposing apparatus 20) of the present embodiment, the reduction effect database 223 in which the degree of stress reduction expected from the activity experience is associated is referred to. Therefore, the combination of activities is selected so as to reduce the stress of the prospective participants. Therefore, it is possible to propose a specific activity plan (solution means) for reducing stress to prospective participants.
Further, when the stress reduction degree of the participant is reflected in the reduction effect database 223, more sample data can be obtained, so that the stress reduction effect can be grasped more objectively.
If the stress of participants is reduced by implementing the activity plan, the mental status of the participants will be improved, and it will have a positive impact on work and personal life. In addition, when a participant likes an activity related to the proposal and becomes a repeater of the activity, the participant has increased his hobbies (enjoyment other than work), which leads to enhancement of his life.
Furthermore, if a participant likes a travel destination and moves to that place, it is thought that it will lead to an improvement in working style such as telework and a proposal for a second life.
In addition, if the activity plan includes the implementation of activities in a village or if migration is carried out, it will lead to revitalization of the economy of the place and activation of human exchange at the place.

In addition, when the mitigation effect database 223 is associated with a plurality of activities and the degree of stress reduction due to the experience of the corresponding activity under a predetermined weather condition, A combination of activities can be selected according to the expected weather conditions. Alternatively, when a plurality of activities and the degree of stress reduction due to the experience of the corresponding activity in a predetermined season are associated with the mitigation effect database 223, the season to which the participation schedule for the activity of the prospective participant belongs The combination of activities can be selected according to
By taking into account the analysis of the environmental factors depending on the weather and season, it is expected that the participants will avoid feeling uncomfortable while traveling and that the stress reduction effect of the participants by the activities will be enhanced.

  Further, in the case where a plurality of activities and the degree of stress reduction corresponding to the attribute of the experiencer of the corresponding activity are associated with the mitigation effect database 223, the combination of activities according to the attribute of the prospective participant Can be selected. By taking into account the attributes of prospective participants, it is possible to select activities according to the preferences of the participants, and it is expected to increase the stress reduction effect of the participants.

  Moreover, in the stress reduction plan proposal system 1 (plan proposal apparatus 20) of this embodiment, the combination of activities can be selected according to the number of days of participation in the activities of the prospective participants. By proposing an appropriate number of activities according to the number of days traveled, it is expected to increase the stress reduction effect of the participants. For example, if the activity plan is overcrowded, participants may get tired instead.

  As a modification of the above-described embodiment, there is a case where the above-described stress reduction plan proposal system is applied to daily life. In other words, in the above embodiment, the measuring device measures the stress reduction effect due to the activity in advance, but in addition, measures the stress level in daily life (for example, the stress level during work in the workplace). You may make it do.

  For example, the user terminal is, for example, a smartphone or a wearable device, and is connected to a heart rate meter or a pulse meter (measuring device) so as to be able to communicate with each other in a wired or wireless manner. The user terminal continuously receives heart rate variability during daily life from the measuring device, and calculates a stress level (for example, LF / HF value or ΔLF / HF described later) from the received data. In this case, the calculation of the LF / HF value as an example of the degree of stress is performed according to the procedure described in relation to FIG. 8 (S11 to S15) in the above embodiment. The calculation of the degree of stress may be executed by the plan proposal device, and the result may be transmitted to the user terminal.

  When the degree of stress exceeds a predetermined threshold (LF / HF value, for example, 5.0), the user terminal notifies an alert that prompts an action for stress reduction. The notification method may be, for example, sound generation through a speaker or pop-up display on the screen of the user terminal. In addition, the user terminal transmits a proposal request to the plan proposal device. In this case, the proposal request may specify a provisional itinerary according to the severity of stress (for example, the greater the severity of stress, the closer to the measurement date), and the itinerary. It does not have to be. The proposal request may include the subject's attributes.

  The plan proposal device 20 that has received the proposal request creates a plan in accordance with the plan creation procedure (FIG. 9) in the above-described embodiment, and sends it back to the user terminal. The user terminal displays the received plan on the screen and proposes participation of the plan to the subject.

  Thereby, a subject's mental state in daily life, such as a workplace, can be grasped in real time. Therefore, both the subject and the employer can objectively determine the work / work with a great mental load, which can be used for grasping and improving the work environment. In addition, since the subject can receive the mitigation plan when the stress increases, the subject can propose a stress mitigation plan in a timely manner.

  In addition, as a variation of the above-described modification, the degree of stress is measured at multiple workplaces of the same type (for example, welfare facilities such as nursery schools and nursing homes, educational facilities such as kindergartens, factories, etc.), and the measurement results are compared. May be. As a result, it is possible to grasp the relative superiority or inferiority of the working environment with other companies in the same industry, and it can be used for improvement.

  Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.

  For example, in the present embodiment, the plan proposing device 20 is connected to the weather database 21, but the present invention is not limited to this. It is good also as a form connected to the computer which calculates a predicted value.

  In the present embodiment, the plan proposal device 20 selects an activity to be included in an activity plan in response to a request from the user terminal 10, but for a plurality of plans, activities included in the plan for each plan in advance. May be stored, and the plan may be selected according to the degree of reduction corresponding to the activity included in each plan.

  Moreover, the plan proposal apparatus 20 does not need to evaluate a mitigation degree. That is, the plan proposal device 20 may present an activity in association with the degree of reduction, and allow the user to select an activity. In this case, the user can set a plan according to his / her preference while comparing the degree of liking the activity with the degree of stress reduction effect expected by experiencing the activity.

  In the present embodiment, the number of people who can participate in the activity is not considered. However, when the upper limit of the number of participants is set in the activity, the plan proposing device 20 reduces the stress using the number of participants as a constraint. You may make it select the combination of activities that makes the total degree of the lowest.

  Further, in the present embodiment, the plan proposing device 20 performs aggregation of the degree of stress reduction (calculation of representative values) according to the season and the weather. Alternatively, an approximate model may be created using the attribute or the like as an explanatory variable and the stress reduction degree as an objective variable, and the stress reduction degree of the activity may be evaluated using the approximate model.

  In the present embodiment, the RRI data is used as it is to obtain the LF / HF value. However, before the LF / HF value is calculated, it is preferable to perform filter processing for noise removal on the RRI. It is.

  Moreover, in this embodiment, although the reference value of LF / HF value was set with the fixed value (5.0), you may change for every test subject. For example, when the subject is in a sitting position, the heart rate is measured for a predetermined time (for example, any time such as 5 minutes, 10 minutes, etc.), and the LF / HF value at that time is calculated. Further, a ratio (ΔLF / HF) to the LF / HF value measured after the experience may be used as the evaluation value. In this case, standardization that absorbs individual differences can be performed.

In addition, when a stress check of participants in the activity is performed and measurement data is transmitted to the stress reduction plan proposal system (plan proposal device), the stress reduction plan proposal system has an upward trend in stress, and When a predetermined threshold is exceeded, an alert may be issued to the measuring device corresponding to the participant. Thereby, while being able to grasp | ascertain the mental state of a participant in real time, a participant can be immediately notified of a stress condition.
At the same time, it is possible to grasp the subjective stress situation by conducting questionnaires to participants in the activity before and after the experience.
