<Overview of user status determination while using the sauna>
An overview of determining the state of a user while using the sauna will be explained with reference to FIG. 1.

Figure 1 is a schematic diagram for explaining an overview of a user's state determination by a state determination device 100 according to one embodiment. Here, it is assumed that a user U is using sauna 1. Details of sauna 1 will be described later.

The state determining device 100 determines the state of the user U who is using the sauna 1. For example, the state determining device 100 determines the degree of well-being of the user who is using the sauna 1, which indicates the degree of well-being of the user's mind and body. The state determining device 100 also determines whether the user U has entered at least one of a relaxed state and an awake state. The state determination device 100 determines the state of the user U by performing the following processing.

The state determination device 100 first acquires biometric information of the user U who is using the sauna 1 (process (1) in FIG. 1). The state determination device 100 acquires information such as the user U's brain waves and heart rate as biological information.

Next, the state determination device 100 determines whether the user U using the sauna 1 is in at least one of a relaxed state and an awake state based on the acquired biometric information (process (2) in FIG. 1). For example, the state determination device 100 compares the acquired biometric information with a previously learned determination model to determine whether the user U is in a relaxed state or an awake state.

Next, the state determination device 100 notifies the user U of the determination result (process (3) in FIG. 1). For example, when the state determining device 100 determines that the user is in a relaxed state or an awake state, it notifies the user to that effect. Thereby, the user U who is using the sauna 1 can easily understand whether he is in a relaxed state or an awake state.

<Sauna configuration>
FIG. 2 is a schematic diagram for explaining the configuration of the sauna 1 used by the user. As shown in FIG. 2, the sauna 1 includes a sauna room 10, a cold water unit 20, and an outside air bath section 30. The sauna room 10, cold water unit 20, and outside air bath section 30 are separated by a wall or the like. Although the sauna 1 can be used by an individual here, it may be used by a plurality of people.

The sauna room 10 is a room where steam bathing and hot air bathing are possible. The sauna room 10 is divided to maintain a predetermined temperature, and warms the body of the user inside the room. For example, the sauna room 10 is provided with heated sauna stones, and when water is poured on the sauna stones, steam is produced and humidity is increased.

The cold water unit 20 is the part that brings cold water into contact with the user whose body has been warmed in the sauna room 10. Here, the cold water unit 20 is a cold water bath. However, this is not limited to this, and the cold water unit 20 may also be a shower. The user cools his or her body by coming into contact with the cold water from the cold water unit 20.

The outdoor bath section 30 is a room where the user can take an outdoor bath. The outdoor bath section 30 is provided with chairs 32, and the user can sit on the chairs 32 and take a rest. While the user is taking an outdoor bath in the outdoor bath section 30, the user's biological information is measured by sensors, etc.

In the sauna 1, the user uses the partitioned sauna room 10, the cold water unit 20, and the outdoor air bath section 30, in that order. In particular, by using the sauna room 10, the cold water unit 20, and the outdoor air bath section 30 multiple times (e.g., three sets), the user will achieve a state of mind and body that is in balance. When the user is in a state of balance, they are more likely to become relaxed and alert.

<Configuration of state determination device>
The configuration of the state determination device 100 will be described with reference to FIG. 3.

FIG. 3 is a schematic diagram for explaining the configuration of the state determination device 100. The state determination device 100 includes a storage section 110 and a control section 120, as shown in FIG.

The storage unit 110 is a storage medium including a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 110 stores a program executed by the control unit 120. The storage unit 110 stores a judgment model that specifies the reference values of bioinformation when a user using the sauna 1 is in at least one of an awakened state and a relaxed state. The storage unit 110 stores a judgment model in association with each user. Details of the judgment model will be described later.

The control unit 120 is, for example, a CPU (Central Processing Unit). The control unit 120 executes the programs stored in the memory unit 110 to function as a biometric information acquisition unit 121, an environmental information acquisition unit 122, a subjective information acquisition unit 123, a learning unit 124, a state determination unit 125, a notification control unit 126, and a parameter setting unit 127.

The biological information acquisition unit 121 acquires biological information of a user who is using the sauna 1. The biological information acquisition unit 121 acquires, for example, a user's brain waves, heart rate, and pulse wave as biological information. Brain waves are measured by a brain wave sensor, heart rate is measured by a heartbeat sensor, and pulse wave is measured by a pulse wave sensor, and the biological information acquisition unit 121 acquires the measured values of these sensors. The above sensor is provided, for example, in a user terminal such as a wearable terminal worn by the user U. The biometric information acquisition unit 121 can obtain biometric information for each user by receiving a user ID that identifies the user and the measured value of the sensor from the user terminal.

The biometric information acquisition unit 121 acquires biometric information when the user repeatedly uses the sauna room 10, the cold water bath, and the outdoor air bath. That is, the biometric information acquisition unit 121 acquires changes in the user's biometric information when the user repeatedly uses the sauna room 10, the cold water unit 20, and the outdoor air bath section 30. The biometric information acquisition unit 121 acquires the user's biometric information when the user is taking an outdoor air bath in the outdoor air bath section 30.

The environmental information acquisition unit 122 acquires environmental information of the sauna 1. In this embodiment, the environmental information acquisition unit 122 acquires a plurality of environmental parameters that set the environmental status of the sauna 1 that the user is using. The environmental information acquisition unit 122 acquires the temperature, humidity, and usage time of the sauna 1 as a plurality of environmental parameters. For example, the environmental information acquisition unit 122 acquires the temperature, humidity, and usage time of the sauna room 10, the temperature, humidity, and usage time of the cold water unit 20, and the temperature, humidity, and usage time of the outside air bath unit 30.

The subjective information acquisition unit 123 acquires subjective information about the effect of the sauna from the user while using sauna 1. For example, the subjective information acquisition unit 123 acquires the information in the form of a questionnaire via a wearable device while the user is taking an outdoor bath. The subjective information may evaluate the effect of using the sauna on a five-point scale, for example.

FIG. 4 is a schematic diagram for explaining an example of acquiring biological information, environmental information, and subjective information. For convenience of explanation, FIG. 4 shows information acquired in the first set of the three sets in which the user uses the sauna room, cold bath, and outdoor air bath. As environmental information, the temperature, humidity, and usage time of the sauna room, cold bath, and outdoor air bath are shown. The subjective information shows the answers of the users who are taking a bath in the open air. As biological information, the magnitude of the alpha wave component and the magnitude of HF, which is an activity index of the parasympathetic nerves, are shown here.

The learning unit 124 performs learning using the acquired biological information, environmental information, and subjective information in order to generate a determination model that is a reference model for determining the level of orderliness of a user who uses the sauna 1. The learning unit 124 generates, for example, a determination model that maximizes the α wave of the brain wave or a determination model that maximizes the HF. The learning unit 124 performs the following processing to generate a determination model.

First, the learning unit 124 calculates the average value and standard deviation of the biological information. For example, the learning unit 124 calculates the average value N and standard deviation σ of α waves and HF. The learning unit 124 uses the obtained average value N and standard deviation σ to allocate the degree of orderliness. For example, the learning unit 124 assigns the user's orderliness within the range of N±2σ. The learning unit 124 stores, in the storage unit 110, a determination model that includes the average value and standard deviation of the biological information and information that assigns a degree of order.

FIG. 5 is a schematic diagram for explaining an example of calculating the average value N and standard deviation σ. Here, for convenience of explanation, the environmental parameters of the sauna room 10 when used three times in the past are shown. The learning unit 124 calculates the average value N and standard deviation σ of the α waves. The average value N of the three α waves is 80, and the standard deviation σ is 18.7.

As can be seen from FIG. 5, among the environmental parameters of temperature, humidity, and usage time, temperature is correlated with alpha waves. For this reason, the learning unit 124 sets temperature as an important environmental parameter. Furthermore, the learning unit 124 sets the temperature value at which the alpha wave value is maximum (here, 100°C) as the important environmental parameter value.

Figure 6 is a schematic diagram for explaining an example of allocating the degree of alignment. As shown in Figure 6, the learning unit 124 allocates the degree of alignment to five levels using the average value N and standard deviation σ of alpha waves. For example, when the value of alpha waves is 60, the degree of alignment is 2.

The state determination unit 125 determines the state of the user while using sauna 1. For example, the state determination unit 125 determines the degree of wakefulness and relaxation of the user while using sauna 1. In this embodiment, the state determination unit 125 determines whether the user is in at least one of an wakefulness state and a relaxation state based on the biometric information acquired by the biometric information acquisition unit 121. Note that the state determination unit 125 may determine whether the user is in both an wakefulness state and a relaxation state.

The state determining unit 125 can determine whether the user is in at least one of an awake state and a relaxed state based on the frequency of the user's brain waves as biological information. Types of brain waves are classified into alpha waves, beta waves, etc., depending on the size of the frequency. Alpha waves are more likely to appear when a person is relaxed, and beta waves are more likely to appear when a person is awake. Therefore, the state determining unit 125 determines that the user is in a relaxed state when the degree of appearance of alpha waves in brain waves is more than a predetermined value, and when the degree of appearance of beta waves in brain waves is more than a predetermined value, It is determined that the user is awake. Note that the state determining unit 125 may determine that the user is in an awake state when the δ wave of the brain wave is decreasing.

The state determination unit 125 can determine whether the user is in at least one of an awake state and a relaxed state based on the user's heart rate as biometric information. It is known that when a person is in a relaxed state, the heart rate is usually low. Therefore, when the heart rate is lower than a predetermined value, the state determination unit 125 determines that the user is in a relaxed state or an awake state.

The state determination unit 125 can determine whether the user is in at least one of an awake state and a relaxed state based on the waveform of the user's pulse wave as biometric information. Normally, the balance between the sympathetic and parasympathetic nerves of the autonomic nervous system can be analyzed using the pulse wave. When the parasympathetic nerves are dominant over the sympathetic nerves, the user is likely to be in a relaxed or awake state. Therefore, when the state determination unit 125 determines from the waveform of the pulse wave that the parasympathetic nerves are dominant, it determines that the user is in a relaxed or awake state.

The state determination unit 125 may determine the user's state based on the amount of adrenaline in the blood. The amount of adrenaline in the blood usually increases when the sympathetic nerves are stimulated. Therefore, the state determination unit 125 determines that the user is in an awakened state when the amount of adrenaline is greater than a predetermined amount.

The state determination unit 125 determines whether the user is in at least one of an awake state and a relaxed state based on the reference value of the determination model stored in the storage unit 110 and the value of the bioinformation acquired by the bioinformation acquisition unit 121. Here, the state determination unit 125 determines whether the user is in an awake state or a relaxed state based on the average value N and standard deviation σ of the bioinformation of the determination model and the value of the acquired bioinformation. For example, if the value of alpha waves as the bioinformation is 78, the state determination unit 125 determines that the degree of alignment is 3 with reference to FIG. 6.

The state determination unit 125 compares the value of the important environmental parameter of the determination model with the value of the actual environmental parameter of the sauna 1. When the important environmental parameter is the temperature of the sauna room 10, the state determination unit 125 compares the value of the important environmental parameter with the actual temperature of the sauna room 10.

The notification control unit 126 notifies the user who is using sauna 1. In this embodiment, the notification control unit 126 notifies the user based on the judgment result of the state judgment unit 125. For example, the notification control unit 126 notifies the user's user terminal based on the judgment result and displays the notification on the display unit of the user terminal.

When it is determined that the user is in at least one of an awake state and a relaxed state, the notification control unit 126 notifies the user to that effect. Further, when it is determined that the user is in both an awake state and a relaxed state, the notification control unit 126 notifies the user that the user is ready to use the sauna 1.

The notification control unit 126 may provide a notification indicating the degree of at least one of the wakefulness and relaxation states. This allows the user using sauna 1 to easily understand the degree of wakefulness or relaxation.

The notification control unit 126 provides a notification that prompts the user to take action according to the determination result of the state determination unit 125. For example, if the notification control unit 126 determines that the user is in an awake state or a relaxed state, the notification control unit 126 issues a notification recommending termination of use of the sauna 1.

When the state determination unit 125 determines that the user is not in an awake or relaxed state, the notification control unit 126 issues a notification encouraging the user to use the sauna room 10, the cold bath, and the outdoor bath again. In other words, the notification control unit 126 encourages the user to use the sauna room 10, the cold bath, and the outdoor bath until the user is in an awake or relaxed state.

The notification control unit 126 may issue a notification prompting the user to change the environmental parameters according to the determination result. That is, the notification control unit 126 issues a notification prompting a change in at least one of the temperature, humidity, and usage time according to the determination result. For example, if the degree of wakefulness or relaxation is low, the notification control unit 126 issues a notification urging the user to extend the usage time of the sauna room 10.

The notification control unit 126 may issue a notification to encourage a user to change one of the multiple environmental parameters that has a high correlation with the biological information. For example, as described above, if there is a high correlation between the fluctuation in alpha waves and the fluctuation in the temperature of the sauna room 10, the notification control unit 126 issues a notification to encourage a user to change the temperature of the sauna room 10.

If the state determination unit 125 determines that there is a difference between the important environmental parameter value of the determination model and the actual parameter value, the notification control unit 126 issues a notification urging the user to take action to eliminate the difference. For example, if the obtained temperature of the sauna room 10 is 90°C with respect to the important environmental parameter value of temperature (here, 100°C), the notification control unit 126 controls the temperature of the sauna room 10. Notify the user to increase the temperature.

The parameter setting unit 127 sets the environmental parameters of sauna 1. The parameter setting unit 127 resets the environmental parameters of sauna 1 based on the judgment result of the state judgment unit 125. For example, if the important environmental parameter value of temperature, which is an important environmental parameter (here, 100°C), is the acquired temperature of sauna room 10 is 90°C, the parameter setting unit 127 sets the temperature of sauna room 10 to 100°C.

<Flow of learning process>
The flow of the learning process for generating and storing a determination model used in the state determination process will be described with reference to FIG. 7. Note that although the determination model is generated for each user, the following description will be made using the determination model of one user as an example.

7 is a flowchart for explaining the flow of the learning process. Here, it is assumed that the user performs three sets of bathing in the sauna room 10 of the sauna 1, a cold bath, and an outdoor bath.
First, the biometric information acquisition unit 121 acquires biometric information of the user who is using the sauna 1 (step S102). For example, the biometric information acquisition unit 121 acquires measurement values of the user's brain waves, heart rate, etc. as biometric information. At this time, the biometric information acquisition unit 121 acquires the measurement values together with the measurement time of the biometric information.

Next, the environmental information acquisition unit 122 acquires environmental parameters of the sauna 1 that the user is using (step S104). For example, the environmental information acquisition unit 122 acquires the temperature, humidity, and usage time (staying time) of the sauna 1 (specifically, the sauna room 10, the cold water unit 20, and the outdoor air bath section 30).

Next, the subjective information acquisition unit 123 acquires the user's subjective information (step S106). For example, the subjective information acquisition unit 123 acquires the user's subjective information while the user is taking an outdoor bath in the outdoor bath unit 30. The acquired subjective information is stored in association with each set together with the biological information and the environmental information. Note that the order of steps S102 to S106 is not limited to the above, and for example, the processing of step S104 may be performed after the processing of step S106.

Next, the learning unit 124 generates a judgment model based on the acquired biometric information, environmental parameters, and subjective information (step S108). For example, the learning unit 124 identifies important environmental parameters and assigns a degree of readiness (see FIG. 6).

Next, the learning unit 124 stores the generated determination model in the storage unit 110 (step S110). At this time, the learning unit 124 causes the storage unit 110 to store the determination model for each user. This makes it possible to determine the status of each user. Note that the determination model is updated every time the user uses the sauna 1.

<Flow of status determination processing>
The flow of the process for determining the state of a user who is using the sauna 1 will be described with reference to FIG. 8.

FIG. 8 is a flowchart for explaining the flow of the state determination process. Here, it is assumed that the determination model of the corresponding user is stored in the storage unit 110 through the learning process.

First, the biometric information acquisition unit 121 acquires biometric information of the user who is using the sauna 1 (step S202). For example, the biological information acquisition unit 121 acquires measured values such as a user's brain waves and heart rate as biological information. At this time, the biological information acquisition unit 121 acquires the measurement value as well as the measurement time of the biological information.

Next, the environmental information acquisition unit 122 acquires the environmental parameters of the sauna 1 that the user is using (step S204). For example, the environmental information acquisition unit 122 acquires the temperature, humidity, and usage time of the sauna 1 (specifically, the sauna room 10, the cold water unit 20, and the outdoor air bath section 30).

Next, the state determining unit 125 uses the acquired biological information to determine the state of the user who is using the sauna 1 (step S206). For example, the state determining unit 125 uses the determination model stored in the storage unit 110 and the acquired biological information to determine whether the user is in at least one of an awake state and a relaxed state.

Next, the notification control unit 126 notifies the user based on the result of the user's state determination (step S208). That is, the notification control unit 126 notifies the user who is using the sauna 1 of the result of the state determination. Thereby, the user can grasp whether he or she is in an awake state or a relaxed state. Further, the user can grasp the degree of orderliness and can decide whether to continue using the sauna 1.

Next, the parameter setting unit 127 resets the environmental parameters of sauna 1 (step S210). For example, if the actual environmental parameter value of sauna 1 deviates from the value of the important environmental parameter, the parameter setting unit 127 sets the actual environmental parameter value to the value of the important environmental parameter.

<Effects of this embodiment>
The state determination device 100 of the above-described embodiment determines whether the user is in at least one of an awakened state and a relaxed state based on the biometric information of the user using the sauna 1, and notifies the user based on the determination result.
By providing such a notification, the user using the sauna 1 can know whether he/she is in an alert or relaxed state. For example, the user can know whether he/she is in an alert or relaxed state after going into the sauna room 10 of the sauna 1, the cold bath, and the outdoor bath a predetermined number of times (e.g., three sets).

Furthermore, the present invention makes it possible to contribute to Goal 9 of the Sustainable Development Goals (SDGs) led by the United Nations, "Create a foundation for industry and technological innovation."
