Description

Technical Field

[0001] The present invention relates to an arousal control device, an arousal control method, and a recording medium.

Background Art

[0002] Techniques for acquiring user's biological information and calculating the user's arousal level from the acquired biological information have been proposed (for example, Patent Documents 1 and 2). Here, the arousal level is an index indicating the degree of wakefulness, and the lower the value of the arousal level, the sleepier the subject is.

[0003] In a state where the arousal level is low, the work efficiency often decreases when the user performs work, and it is not an appropriate state for work performance. For example, in office work, the work efficiency decreases, and in automobile driving, distracted driving increases, etc., and there is a tendency to be in an undesirable state for each work.

[0004] Therefore, systems for improving the arousal level or controlling the user's environment so as to be within an appropriate range have been proposed (Patent Documents 3, 4, and 5).

[0005] Patent Document 3 discloses a system for controlling the arousal level for a vehicle driver that changes the settings of environmental control devices such as air conditioners and lighting to predetermined settings when the predicted value of the user's arousal level when the current environmental state continues is below a predetermined threshold.

[0006] Patent Document 4 discloses a system for controlling the arousal level for a vehicle driver that determines and controls the combination and intensity of devices that stimulate the five senses such as air conditioners and lighting based on predetermined settings according to where the user's current state is located in a two-dimensional coordinate system consisting of a sleepiness-arousal evaluation axis and a pleasure-displeasure evaluation axis, particularly how far it is from a desired range.

[0007] Patent Document 5 discloses a system for controlling the arousal level of a driver of a vehicle, which gives the user a thermal and cold stimulus due to a temperature change by periodically switching an air conditioner to a predetermined operation mode (temperature, air volume setting) when the arousal level of the target person falls below a preset threshold value.

[0008] In addition, there is a technology for acquiring and processing user information or information on the surrounding environment thereof. For example, the mood estimation system of Patent Document 6 indexes the mood based only on the heart rate of the target person, and when the index value deviates from a preset range, indexes the mood of the target person based on a plurality of biological information of the target person and a plurality of environmental information of the surrounding environment of the target person.

[0009] In addition, the air conditioning management system described in Patent Document 7 calculates a predicted environmental value after a predetermined time based on the environmental value detected by a detection device, calculates the parameters of the air conditioner based on the environmental value and the predicted environmental value, and transmits them to the air conditioner.

[0010] In addition, in the arousal level maintenance method described in Patent Document 8, the arousal level is detected from the deep body temperature such as the tympanic membrane temperature of the operator, and when a decrease in the arousal level of the operator is observed, the illuminance is changed from an illuminance suitable for the work to a higher illuminance to give the operator an arousal effect by light stimulation.

[0011] In addition, the sleepiness estimation device described in Patent Document 9 includes a neural network having a two-layer structure of an image processing neural network and a sleepiness estimation neural network. The image processing neural network estimates the age and gender of the user, and extracts specific actions and states of the user indicating a sleepy state such as closing the eyes. The sleepiness estimation neural network determines the sleepiness state of the user based on the extraction results of specific actions and states of the user indicating a sleepy state, the detection results of an indoor environment information sensor, and taking into account the age and gender of the user.

[0012] This Patent Document 9 describes that the control unit of the air conditioner calculates the air conditioning control content so that the estimated sleepiness level is equal to or lower than the threshold value, and executes the calculated air conditioning control. Furthermore, Patent Document 9 describes that when no desired change is observed in the user's actions and states, the estimated model should be updated because the estimated operation of the sleepiness state may deviate from the actual sleepiness state.

Modes for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described. However, the following embodiments do not limit the invention according to the claims. Also, not all combinations of features described in the embodiments are essential for the solution means of the invention. FIG. 1 is a schematic block diagram showing an example of the device configuration of the arousal control system 1 according to the embodiment. In the configuration shown in FIG. 1, the arousal control system 1 includes an arousal control device 100, one or more environmental control devices 200, one or more environmental measurement devices 300, and one or more arousal estimation devices 400.

[0022] The arousal control device 100 is connected to each of the environmental control devices 200, each of the environmental measurement devices 300, and each of the arousal estimation devices 400 via a communication line 900 and is communicable. The communication line 900 may be configured in any form regardless of the occupancy form of the communication line such as a dedicated line, the Internet, a VPN (Virtual Private Network), a LAN (Local Area Network), etc., and the physical form of the communication line such as a wired line or a wireless line.

[0023] The arousal control system 1 determines the arousal level of the subject of arousal control, and controls the physical quantity of the surrounding environment of the subject of arousal control according to the determination result to maintain or improve the arousal level. As described above, the arousal level is an index indicating the degree of wakefulness, and the lower the value of the arousal level, the sleepier the subject of arousal control is. The subject of arousal control is also referred to as a user or simply a subject.

[0024] Here, the physical quantity of the surrounding environment of the subject is a physical quantity (physical amount) that affects the subject, and here, in particular, it is a physical quantity that affects the arousal level of the subject. The physical quantity of the surrounding environment of the subject is also simply referred to as a physical quantity. Examples of physical quantities include, but are not limited to, air temperature such as room temperature, and brightness such as illuminance by lighting equipment. For example, in addition to or instead of temperature and brightness, the arousal control system 1 may apply stimuli other than temperature and brightness, such as moisture (humidity), sound, or vibration, to the subject and use the magnitudes of these as physical quantities.

[0025] Hereinafter, air temperature will simply be referred to as temperature. However, in addition to or instead of air temperature, the arousal control system 1 may control other temperatures. For example, a heater may be provided on the seat surface of the subject's seat, and the arousal control system 1 may control the temperature of the heater, such that the arousal control system 1 controls the temperature of objects in direct contact with the subject.

[0026] The unit by which the arousal control system 1 controls the physical quantity is not limited to a specific one. For example, a spot-type air conditioner (local air conditioner) and a lighting stand may be installed at an individual's seat, and the arousal control system 1 may control the physical quantity on a per-seat basis. Alternatively, the arousal control system 1 may control the physical quantity on a per-room basis, or may control the physical quantity of the entire building. Further, when controlling the physical quantity of the entire building, the subject does not have to be all the people in the building, and may be some of the people in the building.

[0027] The number of subjects may be one or plural. Only specific persons such as when the arousal control system 1 accepts registration of the subject may be the subject. Alternatively, unspecified persons located in the control target space of the arousal control system 1 may be the subject. When there are a plurality of subjects, the arousal control system 1 may control the physical quantity for each subject, or may control the physical quantity in common for a plurality of subjects.

[0028] In order to improve the subject's wakefulness, it is conceivable to control physical quantities in a way that may reduce comfort for some people, such as raising the room temperature or increasing the lighting. The wakefulness control system 1 can balance ensuring the subject's wakefulness and comfort by determining the wakefulness of the subject to be controlled for wakefulness and controlling the physical quantity according to the determination result. For example, the wakefulness control system 1 may control the physical quantity so as to improve wakefulness only when the subject's wakefulness decreases.

[0029] Hereinafter, the case where the wakefulness control system 1 improves the subject's wakefulness (awakens drowsiness) will be described as an example, but the wakefulness control system 1 may also decrease the subject's wakefulness (induce sleep). For example, the wakefulness control system 1 may switch and execute control for improving wakefulness and control for decreasing wakefulness according to the time zone. Or, when it is predicted that the subject's wakefulness will decrease, the wakefulness control system 1 may control so that the subject's wakefulness does not decrease (that is, so that the subject does not doze off). Or, when it is predicted that the subject's wakefulness will improve, the wakefulness control system 1 may control so that the subject's wakefulness does not improve (that is, so that the subject does not awaken).

[0030] The wakefulness control device 100 controls the environmental control device 200 according to the subject's wakefulness. The wakefulness control device 100 controls the physical quantity of the subject's surrounding environment by controlling the environmental control device 200, thereby controlling the subject's wakefulness. The wakefulness control device 100 is configured using a computer such as a personal computer (PC) or a work station.

[0031] The environmental control device 200 is a device that adjusts physical quantities. As described above, examples of physical quantities include, for example, air temperature and illuminance. The temperature can be adjusted by an air conditioner, and the illuminance can be adjusted by a lighting device. Thus, examples of the environmental control device 200 include, but are not limited to, an air conditioner and a lighting device. The environmental control device 200 corresponds to an example of a device to be controlled and is controlled by the arousal control device 100 as described above.

[0032] Devices other than the environmental control device 200, such as the arousal control device 100, can acquire information regarding the operating state such as device setting values from the environmental control device 200 and can update the device setting values for the environmental control device 200. Here, the device setting value is a physical quantity set for the environmental control device 200 as a control target value. The device setting value is also referred to as a setting value of a physical quantity, or simply a setting value. When the environmental control device 200 is an air conditioner, the set temperature can be used as the device setting value. When the environmental control device 200 is a lighting device, lighting output (for example, luminous intensity, illuminance, current value, power value, etc.) can be used as the device setting value. Hereinafter, the case where illuminance is used as the device setting value of the lighting device will be described as an example, but it is not limited thereto.

[0033] The environmental measurement device 300 is a device that measures physical quantities such as temperature and illuminance and converts them into numerical data. Examples of the environmental measurement device 300 include, but are not limited to, a temperature sensor and an illuminance sensor.

[0034] The arousal estimation device 400 is a device that estimates the arousal level of a subject from biological information or the like and converts it into numerical data. The arousal estimation device 400 may use, but is not limited to, any one of body temperature, facial video, and pulse wave as biological information, or a combination thereof. The arousal estimation device 400 measures or calculates biological information and converts the obtained biological information into a numerical value (arousal level) indicating the degree of arousal. The arousal level estimation device 400 is not essential for the arousal level control system 1. When the arousal level control system 1 does not include the arousal level estimation device 400, the arousal of the subject is estimated based on physical quantities.

[0035] Next, the functional configuration of the arousal level control device 100 will be described. FIG. 2 is a schematic block diagram showing an example of the functional configuration of the arousal level control device 100. In the configuration shown in FIG. 2, the arousal level control device 100 includes a communication unit 110, a storage unit 170, and a control unit 180. The storage unit 170 includes a physical quantity prediction model 171 and an arousal level prediction model 172. The control unit 180 includes a monitoring control unit 181, a first acquisition unit 182, a second acquisition unit 183, a set value calculation unit 184, a physical quantity prediction model calculation unit 185, an arousal level prediction model calculation unit 186, and a set value determination unit 187.

[0036] The communication unit 110 communicates with other devices according to the control of the control unit 180. In particular, the communication unit 110 receives various information from each of the environment control device 200, the environment measurement device 300, and the arousal level estimation device 400. Also, the communication unit 110 transmits a device set value to the environment control device 200. The storage unit 170 stores various information. The storage unit 170 is configured using a storage device included in the arousal level control device 100.

[0037] The physical quantity prediction model 171 is a model that calculates a predicted value of the physical quantity based on a set value (device set value) of the physical quantity. More specifically, the physical quantity prediction model 171 calculates a predicted value of the physical quantity when a predetermined time has elapsed based on a measured value of the physical quantity measured by the environment measurement device 300 and a set value of the physical quantity set in the environment control device 200.

[0038] When the predetermined time has elapsed in this case, it is after the elapse of the predetermined time from the time when the physical quantity is measured and given to the physical quantity prediction model 171. Instead of the time when the physical quantity is measured and given to the physical quantity prediction model 171, the time when the arousal level control device 100 (communication unit 110) receives the physical quantity can be used. In this case, the predetermined time may be fixed at a constant time or may be variable as a model parameter. The model parameter referred to here is a setting parameter of the physical quantity prediction model 171. The value of the model parameter is referred to as the model parameter value.

[0039] The arousal prediction model 172 is a model that calculates a predicted value of arousal based on the predicted value of the physical quantity calculated by the physical quantity prediction model 171. Furthermore, the arousal prediction model 172 calculates a predicted value of arousal based on the change amount of the physical quantity in addition to the predicted value of the physical quantity. More specifically, the arousal prediction model 172 calculates a predicted value of the change amount of the arousal of the subject when a predetermined time has elapsed based on the physical quantity.

[0040] The control unit 180 controls each part of the arousal control device 100 to execute various processes. The control unit 180 is realized by the CPU (Central Processing Unit) of the arousal control device 100 reading and executing a program from the storage unit 170. The monitoring control unit 181 communicates with the environment control device 200 via the communication unit 110. In the communication with the environment control device 200, the monitoring control unit 181 acquires the device setting value set in the environment control device 200. Also, the monitoring control unit 181 updates the device setting value of the environment control device 200 in the communication with the environment control device 200. For example, the monitoring control unit 181 communicates with the environment control device 200 at regular intervals and stores the device setting value acquired by the communication together with the time stamp at the time of acquisition (reception). The storage referred to here is, for example, to store in the storage unit 170. In this way, the monitoring control unit 181 sets the device setting value in the device to be controlled. The monitoring control unit 181 corresponds to an example of a setting unit.

[0041] The monitoring control unit 181 sets the device setting value, the device setting value calculated by the setting value calculation unit 184, or the device setting value determined by the setting value determination unit 187 in the environment control device 200.

[0042] The first acquisition unit 182 communicates with the environmental measurement device 300 via the communication unit 110, and acquires the measurement value of the physical quantity measured by the environmental measurement device 300. For example, the first acquisition unit 182 communicates with the environmental measurement device 300 at regular intervals, and stores the measurement value of the physical quantity acquired by the communication together with the time stamp at the time of acquisition (reception). This time stamp can be regarded as indicating the time when the physical quantity is measured by the environmental measurement device 300.

[0043] The second acquisition unit 183 communicates with the arousal level estimation device 400, and acquires the estimated value of the arousal level of the subject. For example, the second acquisition unit 183 communicates with the arousal level estimation device 400 at regular intervals, and stores the estimated value of the arousal level acquired by the communication together with the time stamp at the time of acquisition (reception). This time stamp can be regarded as indicating the time when the arousal level is estimated by the arousal level estimation device 400. The estimated value of the arousal level of the subject is also referred to as the arousal level estimated value.

[0044] The set value calculation unit 184 calculates the device set value of the environmental control device 200 so as to improve the arousal level of the user. For example, the set value calculation unit 184 calculates the device set value at regular intervals. The set value calculation unit 184 acquires the device set value from the monitoring control unit 181, acquires the measurement value of the physical quantity from the first acquisition unit 182, and acquires the arousal level estimated value from the second acquisition unit 183, and calculates the device set value based on these. The set value calculation unit 184 outputs the calculated device set value to the monitoring control unit 181. The monitoring control unit 181 sets the device set value acquired from the set value calculation unit 184 in the environmental control device 200 by transmitting it to the environmental control device 200 via the communication unit 110.

[0045] The set value calculation unit 184 calculates the device set value so that the arousal level becomes higher.

[0046] The physical quantity prediction model calculation unit 185 reads out and executes the physical quantity prediction model 171 from the storage unit 170. Therefore, the physical quantity prediction model calculation unit 185 executes the prediction of the physical quantity using the physical quantity prediction model 171. The arousal prediction model calculation unit 186 reads out and executes the arousal prediction model 172 from the storage unit 170. Therefore, the arousal prediction model calculation unit 186 executes the prediction of the arousal level using the arousal prediction model 172.

[0047] The arousal prediction model calculation unit 186 acquires the measured values of physical quantities from the first acquisition unit 182 and the estimated arousal values from the second acquisition unit 183 as learning data.

[0048] The calculation execution of the set value calculation unit 184 is performed according to the procedure shown in FIG. 3 or FIG. 4. It is preferable that the calculation execution is performed at a fixed period with the period being Δτ. FIG. 3 is a flowchart showing a first example of the procedure of the process in which the set value calculation unit 184 calculates the device set value and sets it in the environmental control device 200. FIG. 3 shows an example in which the set value calculation unit 184 calculates the device set value without using the estimated arousal value.

[0049] In the process of FIG. 3, the set value calculation unit 184 determines whether or not the execution timing of the process of calculating the device set value has arrived (step S100). If it is determined that it has not arrived (step S100: No), the process returns to step S100. Thereby, the set value calculation unit 184 waits for the arrival of the execution timing of the process of calculating the device set value. On the other hand, when it is determined that the execution timing of the process of calculating the device set value has arrived (step S100: Yes), the set value calculation unit 184 acquires the device set value from the monitoring control unit 181 (step S110).

[0050] Also, the set value calculation unit 184 acquires the environmental measurement value (the measured value of the physical quantity measured by the environmental measurement device 300) from the first acquisition unit 182 (step S120). Then, the set value calculation unit 184 calculates the device set value (the value for updating the device set value) (step S130). In step S130, the set value calculation unit 184 calculates the device set value without using the estimated arousal value. The set value calculation unit 184 outputs the obtained device set value to the monitoring and control unit 181 (step S140). The monitoring and control unit 181 sets the device set value in the environmental control device 200 by transmitting the device set value obtained from the set value calculation unit 184 to the environmental control device 200 via the communication unit 110. After step S140, the set value calculation unit 184 ends the process of FIG. 3.

[0051] FIG. 4 is a flowchart showing a second example of the procedure of the process in which the set value calculation unit 184 calculates a device set value and sets it in the environmental control device 200. FIG. 4 shows an example in which the set value calculation unit 184 calculates a device set value using the estimated arousal level. Steps S200 to S220 in FIG. 4 are the same as steps S100 to S120 in FIG. 3. After step S220, the set value calculation unit 184 acquires the estimated arousal level from the second acquisition unit 183 (step S230).

[0052] Then, the set value calculation unit 184 calculates a device set value (a value for updating the device set value) (step S240). In step S240, the set value calculation unit 184 calculates a device set value using the estimated arousal level. Step S250 is the same as step S140 in FIG. 3. After step S250, the set value calculation unit 184 ends the process of FIG. 4.

[0053] As described above, the physical quantity prediction model 171 calculates the physical quantity that affects the arousal level of the subject. The arousal level prediction model 172 calculates a predicted value of the arousal level based on the physical quantity calculated by the physical quantity prediction model 171. The set value calculation unit 184 calculates a set value (device set value) for controlling the arousal level of the subject under the constraints related to the physical quantity using the physical quantity prediction model 171 and the arousal level prediction model 172. The monitoring and control unit 181 sets the calculated set value in the environmental control device 200.

[0054] In this way, the physical quantity prediction model 171 calculates the predicted value of the physical quantity, and the arousal level prediction model 172 predicts the arousal level using the physical quantity, so that the physical quantity can be incorporated into the prediction of the arousal level. According to the arousal level control device 100, in this regard, when controlling the arousal level, it is possible to more accurately grasp the influence of the action on the surrounding environment on the arousal level.

[0055] Further, the set value calculation unit 184 calculates a set value so that the arousal level becomes higher. According to the arousal level control device 100, it is possible to improve the arousal level of the subject, for example, when the subject is performing work, it is possible to improve the work efficiency.

[0056] Calculate the total value or average value of the predicted values of the change amounts of the arousal levels for one or more subjects.

[0057] Further, the set value calculation unit 184 calculates a set value that satisfies the constraints regarding the comfort score calculated for the set value. Thereby, the set value calculation unit 184 can calculate a set value that takes into account not only the arousal level but also the comfort. In this regard, the arousal level control device 100 can balance the arousal level and the comfort.

[0058] Further, the arousal level prediction model 172 calculates a predicted value of the arousal level based on the physical quantity. It is considered that the arousal level is sensitive to the magnitude of the physical quantity, and it is expected that the arousal level prediction model 172 can predict the arousal level with high accuracy by predicting the arousal level based on the magnitude of the physical quantity.

[0059] Next, the configuration of the embodiment of the present invention will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of the configuration of the arousal level control device 10 according to the embodiment. The arousal level control device 10 shown in FIG. 5 includes a physical quantity prediction model 11, an arousal level prediction model 12, a set value calculation unit 13, and a setting unit 14. With such a configuration, the physical quantity prediction model 11 calculates a predicted value of the physical quantity based on a set value of the physical quantity that affects the arousal level of the subject. The arousal level prediction model 12 calculates a predicted value of the arousal level based on the predicted value. The set value calculation unit 13 calculates the set value for controlling the arousal level of the subject under the constraint related to the physical quantity, using the physical quantity prediction model and the arousal level prediction model. The setting unit 14 sets the calculated set value in the control target device that affects the physical quantity.

[0060] In this way, by having the physical quantity prediction model 11 calculate a predicted value of the physical quantity and the arousal level prediction model 12 predict the arousal level using the predicted value of the physical quantity, the possibility of a change in the physical quantity can be incorporated into the prediction of the arousal level. According to the arousal level control device 10, in this regard, when controlling the arousal level, the influence exerted on the arousal level by the action on the surrounding environment can be grasped more accurately.

[0061] The configuration of the arousal level control device 100 is not limited to a configuration using a computer. For example, the arousal level control device 100 may be configured using dedicated hardware such as being configured using an ASIC (Application Specific Integrated Circuit).

[0062] The present invention can also be realized by causing a CPU (Central Processing Unit) to execute a computer program for any processing. In this case, the program can be stored using various types of non-transitory computer readable media and supplied to a computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer readable media include magnetic recording media (such as flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (such as magneto-optical disks), CD-ROM (Read Only Memory), CD-R, CD-R / W, DVD (Digital Versatile Disc), BD (Blu-ray (registered trademark) Disc), and semiconductor memories (such as mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (Random Access Memory)).
