[0029] Hereinafter, the device control system, device control apparatus, device control method and device control program of the embodiments will be described with reference to the drawings. The following embodiments are merely examples, and the embodiments can be appropriately combined and modified.

[0030] 《1》Implementation Method 1

[0031] Structure of 1-1

[0032] Figure 1 This is a block diagram schematically showing the structure of the device control system 1 of the first embodiment. The device control system 1 is a system for bringing the state of a plurality of people (e.g., party participants) located in the target area 60 close to the target state. The plurality of people located in the target area 60 may be people who have no relationship with each other (i.e., strangers to each other). In addition, the plurality of people located in the target area 60 may be people who gather in a public place (e.g., in a train, a shopping mall, a school, or a hospital, etc.). Figure 1 In the figure, the object area 60 is represented as one area, but the object area 60 may be composed of a plurality of areas in which a conference system (for example, a video conference system, a Web conference system, etc.) is provided, which is a communication system that enables people located in remote locations to become participants in a gathering.

[0033] The target state of the multiple people located in the object area 60 is, for example, the target of the party set by the participants of the party or the manager who manages the party. For example, in the case where the goal of the party is to obtain a useful conclusion through active discussion, a high activity (for example, a high value corresponding to the high activity) indicating an increase in the activity of the actions of the multiple people participating in the party (for example, the activity of the discussion) is set as the target state. In addition, in the case where it is desired to avoid the appearance of an overactive person (for example, an overexcited person), a low activity (for example, a low value corresponding to the low activity) indicating a decrease in the activity of the actions of the multiple people participating in the party is set as the target state. In addition, the target state of the multiple people located in the object area 60 can also be determined based on the state of a specific person (for example, a specific person set in advance, one or more than two people) among the multiple people gathered in the object area 60. That is, as the target state of the multiple people located in the object area 60, it is not necessary to use the states of all the multiple people gathered, and the states of more than one representative (for example, the person in charge of the party) among the multiple people gathered can be used. In the case where the object area 60 is within a residence, the state of someone in the family can also be used as the target state of the multiple people located in the object area 60.

[0034] It is believed that there is a positive correlation between the activity of a person's actions and the person's excitement. In addition, the person's excitement can be measured based on the person's physical state (for example, biological information). For example, the increase in a person's excitement can be measured based on physical states such as an increase in body temperature, an increase in pulse rate, an increase in blood pressure, an increase in speech volume, an increase in speech speed, and a posture when speaking. In this way, the device control system 1 is a system that measures the activity of the actions of multiple people (usually referred to as the "occasion atmosphere" formed by the gathering of multiple people) by detecting the physical states of the multiple people when multiple people gather, and controls the equipment (for example, electrical equipment) so that the environment of the object area 60 is changed to a state corresponding to the set target state.

[0035] The device control system 1 has a device 30 that changes the environment of the target area 60, an environment detection unit 40 that detects the state of the environment of the target area 60, a body state detection unit 50 that detects the body state of a person located in the target area 60, and a device control device 10 as an information processing device that controls the device 30. The device control system 1 may also have a plurality of devices 30, a plurality of environment detection units 40, and a plurality of body state detection units 50. The plurality of device control devices 10 are devices that can implement the device control method of embodiment 1. The device control device 10 is, for example, a computer that can execute the device control program of embodiment 1. The device 30, the environment detection unit 40, and the body state detection unit 50 are connected to the device control device 10, for example, via a wired or wireless network. Examples of the network include a LAN (Local Area Network), a WAN (Wide Area Network), and the Internet. The environment detection unit 40 may also be provided as a part of the device 30. Afterwards, the device 30 is used Figure 4 A specific example of the device 30 will be described.

[0036] Figure 2 This is a block diagram schematically showing the configuration of the device control device 10 according to Embodiment 1. The device control device 10 includes a target acquisition unit 12 , an environment information acquisition unit 13 , a physical condition information acquisition unit 14 , and a control unit 11 .

[0037] The target acquisition unit 12 acquires target information A0 indicating the target state of the actions of a plurality of persons (e.g., participants of a party) located in the target area 60 and provides the target information A0 to the control unit 11. The target information A0 is obtained, for example, from an input unit (described later) for human operation. Figure 3 The target information A0 is input to the target acquisition unit 12 as shown in the figure. For example, the target acquisition unit 12 acquires a target value A1 indicating the level of activity of the actions of a plurality of people located in the object area 60 as the target information A0, and provides the target value A1 to the control unit 11. In addition, the target acquisition unit 12 or the control unit 11 may also dynamically change the target information A0. For example, in a case where the target information A0 is set by a target value, the target information A0 may also be changed dynamically, such as being set to a value for making the discussion active in the first half of the party and being set to a value for making the discussion calm in the second half of the party. In addition, in a case where the participants of the party are too excited, the target information A0 may be automatically changed to a value for calming the participants.

[0038] The environmental information acquisition unit 13 acquires environmental information B0 indicating the state of the environment of the target area 60 where a plurality of people are located from the environmental detection unit 40, and provides the environmental information B0 to the control unit 11. In the case where the environmental detection unit 40 is provided as a part of the device 30, the environmental information B0 may include device status information indicating the state of the device 30. For example, the environmental information B0 may also be an output signal of a temperature sensor provided independently of an air conditioner serving as the device 30, or may be device status information (for example, an output signal of a temperature sensor provided in the air conditioner or a set temperature of the air conditioner, etc.). However, the device status information may also be provided directly from the device 30 to the control unit 11 via the network. Then, the device status information is used. Figure 5 A specific example of the environment detection unit 40 will be described.

[0039] The body state information acquisition unit 14 acquires body state information C0 indicating the body states of a plurality of persons located in the target area 60 from the body state detection unit 50, and provides the body state information C0 to the control unit 11. The body state information C0 is information indicating the excitement of a person and the activity of a person's action. Figure 6 A specific example of the body state detection unit 50 will be described.

[0040] The control unit 11 controls the device 30 based on the target information A0, the environmental information B0, and the body state information C0 so that the state of the movement of the multiple people in the target area 60 approaches the target state. The environmental information B0 includes the device state information. That is, the control unit 11 may estimate the brightness of the target area 60 based on the state of the lighting device instead of detecting the brightness of the target area 60 through the illuminance sensor. In this case, the control unit 11 controls the device 30 based on the target information A0, the device state information as the environmental information B0, and the body state information C0 so that the state of the movement of the multiple people in the target area 60 approaches the target state. In addition, the control unit 11 may estimate the temperature of the target area 60 based on the set temperature and operating state of the air conditioner instead of detecting the temperature of the target area 60 through the temperature sensor. When the target acquisition unit 12 acquires a target value (i.e., an activity target value) A1 indicating the level of activity of the actions of multiple people as the target information A0, the control unit 11 calculates a current value (i.e., an activity current value) A2 indicating the level of activity of the actions of multiple people based on the body state information C0, and controls the device 30 to create an environment in which the current value A2 is close to the target value A1.

[0041] The activity of the actions of multiple people is a value calculated based on the activity of each of the actions of the multiple people. The current value of the activity of the actions of multiple people is, for example, a statistical value of multiple current values ​​of the activity of the actions of multiple people (e.g., average value, weighted average value, median value, etc.), or the current value of the activity of the actions of one representative among the multiple people, or a statistical value of multiple current values ​​of multiple representatives among the multiple people (e.g., average value, weighted average value, median value, etc.).

[0042] Specifically, when the difference between the current value A2 of the activity and the target value A1 of the activity is greater than or equal to a predetermined first threshold value T1 and the current value A2 is lower than the target value A1, the control unit 11 controls the device 30 so as to create an environment in which the activity is increased. The control of the device 30 in which the activity is increased is, for example, control of an air conditioner for increasing the temperature of the target area 60, control of a lighting device for brightening the target area 60, control of a lighting device for changing the color of the illumination light of the target area 60 from daylight white to daylight color, control of an audio device for playing fast-tempo music in the target area 60, and control of an electric blind for opening the blind of the window, or a combination of two or more thereof. However, the control content of the device 30 for changing the environment is not limited to these or a combination of two or more thereof.

[0043] In addition, when the difference between the current value A2 of the activity and the target value A1 of the activity is greater than or equal to the predetermined second threshold value T2 and the current value A2 is higher than the target value A1, the control unit 11 controls the device 30 so as to create an environment in which the activity is reduced. The first threshold value T1 and the second threshold value T2 may be the same value or different values. The control of the device 30 in which the activity is reduced is, for example, the control of an air conditioner for reducing the temperature of the target area 60, the control of an air conditioner, a fan or a ventilator for strengthening the airflow of the target area 60, the control of an aromatherapy machine for providing a calming aroma to the air of the target area 60, the control of a lighting device for reducing the brightness of the target area 60, the control of a lighting device for making the color of the lighting light of the target area 60 closer to daylight white from daylight color, the control of an audio device for playing slow and quiet music in the target area 60, and the control of an electric window for opening a window, etc., or a combination of two or more. However, the control content of the device 30 for changing the environment is not limited to these or a combination of two or more of these.

[0044] Figure 31 is a diagram showing an example of the hardware structure of the device control device 10 of embodiment 1. The device control device 10 is, for example, a computer. The device control device 10 may also be on a cloud service (cloud server). The device control device 10 has a processor 101, a memory 102, a storage unit 103 as a non-volatile storage device, an interface 104, a communication unit 105, and an input unit 106. The processor 101 is a CPU (Central Processing Unit) or the like. The memory 102 is, for example, a volatile semiconductor memory such as a RAM (Random Access Memory). The storage unit 103 is a storage device such as a hard disk drive (HDD) or a solid state drive (SSD). The storage unit 103 stores information and programs. The communication unit 105 communicates with other devices via a network. The input unit 106 is an operating unit such as a keyboard as an input interface. The input unit 106 receives input from a person. Devices such as the environment detection unit 40 and the body state detection unit 50 are connected to the interface 104. In addition, the functions of the device control apparatus 10 may be implemented by a plurality of computers, or a computer and a cloud server.

[0045] Each function of the device control device 10 is implemented by a processing circuit. The processing circuit may be dedicated hardware or a processor 101 that executes a program stored in a memory 102. The processor 101 may be any one of a processing device, a computing device, a microprocessor, a microcomputer, and a DSP (Digital Signal Processor).

[0046] When the processing circuit is dedicated hardware, the processing circuit is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or any combination thereof.

[0047] When the processing circuit is the processor 101, the device control program of the first embodiment is implemented by software, firmware, or a combination of software and firmware. The software and firmware are described in the form of programs and stored in the memory 102. The processor 101 can implement the device control program stored in the memory 102 by reading and executing the device control program. Figure 2The device control program is installed in the device control device 10 by downloading it through a network, or by installing it in the device control device 10 from a recording medium (i.e., a storage medium) that records information, such as an optical disk. In addition, the device control device 10 may be partially implemented by dedicated hardware and partially implemented by software or firmware. In this way, the processing circuit can be implemented by hardware, software, firmware, or any combination thereof. Figure 1 The functions of each functional block are shown.

[0048] Figure 4 1 is a diagram showing an example of a device 30 of the device control system 1 of the first embodiment. The device 30 has at least one of the first electrical device 31 to the fifth electrical device 35 (i.e., a combination of one or more). The device 30 can be connected to the network directly or via a gateway (GW), and can send device status information to the device control device 10 via the network. In addition, for the first electrical device to the fifth electrical device, the devices are classified at the functional level, but such classification is only an example, and other classifications can also be performed. For example, when a robot classified as the fifth electrical device has a function as an audio device, it is also classified as the third electrical device.

[0049] The device state information shows, for example, an operation status indicating an operation performed by a person such as turning on or off the device 30, a setting status indicating a setting of the device 30, or an operation status of the device 30. Here, the device state information includes at least the operation status.

[0050] The first electrical device 31 adjusts the environment associated with the air of the target area 60. The first electrical device 31, for example, changes at least one of the temperature, humidity, airflow, odor, and air quality of the target area 60 (i.e., a combination of one or more). The airflow includes the intensity and direction of the air flow. The air quality is the composition of the air, including the content or concentration of at least one of nitrogen, oxygen, carbon monoxide, carbon dioxide, nitrogen oxides, particles such as dust, and chemical substances such as formaldehyde.

The second electrical device 32 changes, for example, at least one of the brightness, color, and lighting effects (i.e., a combination of one or more) within the target area 60. The change in brightness is a change in illumination. The change in color is a change in the color of the lighting light. Colors include, for example, light bulb color, daylight white, and daylight color. The change in lighting effect is a change in the surface of the irradiated light, such as irradiating the entire room uniformly, irradiating only the ceiling surface, irradiating only the wall surface, irradiating only the ground surface, irradiating the wall surface and the ground surface, or irradiating the ceiling and the wall surface. In addition, the change in lighting effect is performed, for example, by a lighting device installed in the target area 60.

The third electrical device 33, for example, provides at least one of the image and the sound (i.e., a combination of one or more of the images) in the target area 60. The third electrical device 33 includes at least one of an image device such as a display device and an audio device such as an audio player. In this case, the display device can output text, images, animations, and images together with voice. In addition, the audio device can reproduce sound, voice, and music.

[0054] The fifth electrical device 35 is a robot placed in the target area 60. The actions and speech of the healing robot or the animal robot can relieve the excitement of the person. In addition, the actions and speech of the robot supporting the person or the robot cheering the person up can wake the person from the depressed state.

[0055] Figure 5 1 is a diagram showing an example of an environment detection unit 40 of the device control system 1 of the first embodiment. The environment detection unit 40 has at least one of the first environment sensor 41 to the fourth environment sensor 44 (i.e., a combination of one or more). The environment detection unit 40 can be connected to a network and send environment information B0 to the device control device 10 via the network. The environment information B0 can include device status information indicating the status of the device 30. The first environment sensor to the fourth environment sensor may not exist independently, but may exist as a part of the device. In addition, a plurality of environment sensors may also be configured as one unit.

[0056] The first environment sensor 41 detects an environment associated with the air of the target area 60. For example, the first environment sensor 41 detects at least one (i.e., a combination of one or more) of the temperature, humidity, airflow, odor, and air quality of the target area 60. The first environment sensor 41 includes at least one of a thermal image sensor, a human sensor, a temperature sensor, a humidity sensor, a wind direction sensor, an air volume sensor, and an air quality sensor.

[0057] The second environment sensor 42 detects an environment related to the brightness of the target area 60. For example, the second environment sensor 42 detects at least one (i.e., a combination of one or more) of brightness, color, and lighting effect in the target area 60. The second environment sensor 42 includes at least one of an illuminance sensor, a camera, and a device state detection unit of a lighting device.

[0058] The third environment sensor 43 detects an environment associated with an image or sound in the target area 60. For example, the third environment sensor 43 detects at least one (i.e., a combination of one or more) of an image or sound provided in the target area 60. The third environment sensor 43 includes a detection unit for the device state of an image device or an audio device.

[0059] The fourth environment sensor 44 detects an environment associated with a window or a door in the target area 60. For example, the fourth environment sensor 44 detects at least one of the open / closed state of a window, the open / closed state of a blind of a window, and the open / closed state of a door in the target area 60 (i.e., a combination of one or more). The fourth environment sensor 44 includes a detection unit for detecting at least one of the open / closed state of a window, the open / closed state of a blind of a window, and the open / closed state of a door.

[0060] Figure 6 1 is a diagram showing an example of the body state detection unit 50 of the device control system 1 according to Embodiment 1. The body state detection unit 50 includes at least one of the first body state sensor 51 to the fourth body state sensor 54 .

[0061] The first body state sensor 51 mainly detects the vital signs of the body states of multiple people. The first body state sensor 51 detects at least one of the heartbeat, breathing, body temperature and blood pressure of multiple people (that is, a combination of one or more of them). The first body state sensor 51 includes, for example, a life sensor, a thermal image camera, etc. The first body state sensor 51 is, for example, a wearable device or a non-contact life sensor. The first body state sensor 51 may also include a brain wave sensor.

[0062] The control unit 11 can calculate the activity level (e.g., excitement or relaxation) of each person in the target area 60 based on body condition information such as heart rate, respiratory rate or heartbeat interval, or LF / RF (=Low Frequency / Respiratory Frequency=heartbeat fluctuation / respiratory fluctuation) value or RRI (R-RInterval) value calculated from the heartbeat interval. The heartbeat interval RRI is the interval between R waves, and the average or standard deviation of RRI is an index for stress estimation.

[0063] For example, it is known that the blood pressure variation E in the region corresponding to the low frequency (LF) component of the power spectrum (ie, 0.05 Hz to 0.15 Hz) is L The respiratory fluctuation F in the region of the high frequency (HF) component of the power spectrum (i.e., 0.15 Hz to 0.40 Hz) is the Mayer wave. H Here, E L / F H The time integral value can be used as a pressure index (also called "LH / HF index") representing the activity of the sympathetic nerves. Such a pressure index can be used as the activity of each person's actions. In this way, the control unit 11 uses the evaluation method of the Lorenz diagram based on the heart rate interval RRI to determine whether the parasympathetic nerves have become active (that is, whether the relaxation has increased), thereby estimating the activity. The control unit 11 can also calculate the activity based on the sensed state of the person other than the heart rate, the number of respirations, and the heart rate interval.

[0064] The second body state sensor 52 mainly detects the movement of the entire body or body parts (for example, hands, feet, head, etc.) of the body states of multiple people. The second body state sensor 52 includes, for example, a camera, a distance measuring sensor such as LiDAR, and the like.

[0065] The third body state sensor 53 mainly detects at least one of the volume, pitch, and speech speed of the voices of the multiple persons (i.e., a combination of one or more of the above) among the body states of the multiple persons. The third body state sensor 53 includes, for example, a microphone and a voice emotion recognition tool (e.g., a software program) for recognizing emotions (e.g., excitement or relaxation) based on voice.

[0066] The fourth body state sensor 54 mainly detects at least one of the facial expressions and pupils of the plurality of persons in the body states of the plurality of persons. The fourth body state sensor 54 includes, for example, a facial camera and an expression and emotion recognition tool (for example, a software program). The fourth body state sensor 54 estimates the emotion of the person (for example, excitement or relaxation) based on the expression, pupil, etc. of the person. The fourth body state sensor 54 is, for example, smart glasses as a glasses-type sensor.

[0067] The control unit 11 can calculate the activity of a person's actions based on, for example, the person's facial expression, pupil, posture, volume of voice, pitch of voice, speech speed, body movement, body temperature, acceleration, or a combination of two or more of them. In addition, the control unit 11 can also estimate the activity by considering the person's gender, age, and other human attributes when obtaining the person's attribute information (for example, when there is input from the input unit). For example, in the case of a young person, the average value of the heart rate, the average value of the number of respirations, or the average values ​​of both are higher. In addition, in the case of an older person, the average value of the heart rate and the average value of the number of respirations are lower. In addition, the female voice tends to be higher than the male voice. By collecting and storing the attribute data of the person in advance and performing corrections corresponding to the attributes, the calculation accuracy of the activity can be improved.

[0068] Figure 7 is a diagram showing an example of the distribution of activity. Figure 7 In the figure, the horizontal axis represents the activity level and the vertical axis represents the number of people. The control unit 11 can, for example, use the average value or the median value of the activity levels calculated separately as the activity level of the actions of the participants of the party. In addition, the control unit 11 can also use the number of people with activity levels of multiple people as a weight and calculate the activity level based on the value obtained by weighted addition of the activity levels.

[0069] The control unit 11 may also dynamically change the target by receiving feedback from the body state detection unit 50 and the environment detection unit 40. That is, the control unit 11 controls the device 30 so as to provide an environment corresponding to the target state acquired by the target acquisition unit 12, thereby enabling the participants of the party to have a lively discussion and obtain a useful conclusion, or enabling a useful conclusion to be obtained by avoiding the appearance of overly excited people.

[0070] Action

[0071] Figure 8 : is a flowchart showing the processing of the device control device 10 in embodiment 1. First, the control unit 11 obtains target information A0 (for example, target value A1) representing the target state of the actions of multiple people located in the target area 60 via the target acquisition unit 12 (step S11). Next, the control unit 11 obtains environmental information B0 representing the state of the environment of the target area 60 where the multiple people are located from the environmental information acquisition unit 13 (step S12). Next, the control unit 11 obtains body state information C0 representing the body states of the multiple people from the body state information acquisition unit 14 (step S13). In addition, the order of steps S11 to S13 is not limited to Figure 8 The order shown is possible in other orders.

[0072] Next, the control unit 11 calculates the current value A2 of the activity level based on the physical state information C0. Next, the control unit 11 controls the device 30 so as to create an environment in which the current value A2 of the activity level approaches the target value A1.

[0073] Fig. 9 It is shown Figure 8 Flowchart of the calculation process of the current value A2 of the activity level in (step S14). First, the control unit 11 obtains the physical condition information C0 of each person (step S21). Next, the control unit 11 calculates the activity level of each person (ie, the current value of the activity level) based on the physical condition information C0.

[0074] Next, the control unit 11 determines whether the number of calculated activity levels (i.e., the current value of activity levels) is less than the number of people J located in the object area 60. If it is less than the number of people J (yes in step S23), the process returns to step S22 to calculate the activity levels of other people. When the number of calculated activity levels (i.e., the current value of activity levels) is greater than the number of people J (no in step S23), the control unit 11 enters the process into step S24. In addition, the number of people J is the number of people pre-entered from the input unit or the number of people detected based on the camera image. In addition, the threshold used for the judgment of step S23 can also be set to other values ​​such as half of the number of people J located in the object area 60. This is because, even if the activity levels of all persons located in the object area 60 are not calculated, the activity levels of a part of the people can be used to estimate the overall activity levels. In addition, especially when there are people in an excited state, it is believed that this sometimes affects the people around them and increases the overall activity level. Therefore, when there are more than one person with abnormally high activity values ​​(an activity threshold is set for detecting extremely excited people, and when there are more than one person with activity levels above this threshold), the device can also be controlled to reduce the activity level.

[0075] Fig.10 This is a flowchart showing the control of the device 30 by the device control apparatus 10 according to Embodiment 1. The control unit 11 determines the control content of the device 30 for changing the environment of the target area 60 based on the current value of the activity level, the environment information, and the device state information (which may also be obtained as the environment information) (steps S31 and S32). Then, the control unit 11 controls the device 30 according to the determined control content.

[0076] 《1-3》Effect

[0077] As described above, according to Embodiment 1, the states of the plurality of persons located in the target area 60 can be brought close to the target state. For example, according to Embodiment 1, the device 30 can be controlled so that when the activity of the actions of the participants of a party is too high and the discussion is too intense, the activity is reduced (i.e., calmed down), or when the party is too quiet, the activity is increased (i.e., activated).

[0078] In addition, the above-mentioned activity level may also include information other than numerical values. For example, the activity level may also be accompanied by information indicating coordinates or a range determined by a two-dimensional area (or three-dimensional space) within the object area 60. That is, the information indicating the activity level of the actions of the party participants may also be set to a different value for each place within the object area 60.

[0079] 《1-4》Variant 1

[0080] Next, the device control system of variant example 1 of implementation example 1 is described. In variant example 1, a case is described in which the target area 60 is a public place for use by multiple people (for example, inside a train, a shopping mall, a school, or a hospital, etc.). In public places for use by multiple people, a low-activity state is often required as a target state for multiple people so that multiple people can maintain a stable mood. In variant example 1, the following example is described: the target area 60 is a public place for use by multiple people, the target persons are multiple people gathered in the public place, and a low-activity state is set as the target state. In addition, in the description of variant example 1, reference is made to Figures 1 to 6 .

[0081] In the device control system of variant example 1, with respect to multiple people (or representatives of a minority of the multiple people) in a public place serving as an object area 60, changes in sound, body movements, or both are detected, and based on the detection results, body state information of the people in the object area 60 is obtained, and the activity level of the people in the object area 60 is detected based on the body state information.

[0082] The device control system of variant example 1 controls the operation of the device 30 so that the states of the multiple people in the object area 60 approach the target state when there is a person whose voice volume has suddenly increased (for example, a person who is determined to be in an excited state based on the volume of the voice), when there is a person who has suddenly become excited (for example, a person who is determined to be in an excited state based on intense body movements), or when both of them are detected.

[0083] Specifically, the device control system of variant example 1 performs "giving strong stimulation for making the person aware that the person is in an excited state" (giving the first stimulation) as the first stage, and performs "giving stimulation for easing and calming the excited state" (giving the second stimulation different from the first stimulation) as the second stage.

[0084] Examples of the first stage of stimulation include rapidly blowing cold air (e.g., air whose temperature is lower than the room temperature by a preset temperature) from an air conditioner toward the people in the target area 60, emitting a loud sound (e.g., a siren, a warning sound) from an audio device toward the people in the target area 60, and emitting a strong light (e.g., a flash of light that occurs in an instant) from a lighting device toward the people in the target area 60. The first stage of stimulation may also be a combination of two or three of rapidly blowing cold air, emitting a loud sound that causes a startle from an audio device, and emitting a strong light that causes a startle from a lighting device.

[0085] As the stimulation in the second stage, there are examples of outputting music having a calming effect from an audio device toward the people in the target area 60, releasing a calming aroma from an aroma diffuser toward the people in the target area 60, and outputting a calming image from an image device toward the people in the target area 60. The stimulation in the second stage may also be a combination of two or three of outputting music, releasing aroma, and outputting images.

[0086] As described above, according to the device control system of variant example 1 of implementation example 1, it is possible to effectively provide stimulation for bringing the state of an unspecified majority of people (for example, the state of people in an excited state) in a target area 60, i.e., a public place such as a train, a shopping mall, a school, or a hospital, close to a target state (for example, a state of low activity).

[0087] 《1-5》Variant 2

[0088] Next, the device control system of variant example 2 of implementation example 1 is described. In variant example 2, a case is described in which the object area 60 is a public place for use by multiple people (for example, an event venue such as a concert venue, a movie theater, a theater, an arena, etc.). In concert venues (for example, inside or outside a building where a live concert is held), movie theaters, theaters, sports arenas, etc., a high-activity state is often required as a target state for multiple people so that multiple people can maintain a sense of excitement and openness, etc. In addition, depending on the conditions provided by the object area 60 (for example, the music, images, performances, and competitive content provided), a low-activity state is sometimes required as a target state for multiple people in order to suppress the activity of multiple people in the public place. In the device control system of variant example 2, the following example is described: the object area 60 is a public place for use by multiple people, the target persons are multiple people gathered in the public place, and a high-activity state is set as the target state. In addition, in the following description, reference is made to Figures 1 to 6 .

[0089] In the device control system of variant example 2, changes in sounds (for example, cheering, support, clapping), body movements (for example, standing up, raising hands, dancing, etc.), or both made by people in a public place serving as the object area 60 are detected, and based on the detection results, body state information of multiple people in the object area 60 is obtained, and the activity levels of multiple people in the object area 60 are detected based on the body state information.

[0090] When the device control system of variant example 2 determines that the state of the multiple people in the target area 60 (or the state of a representative minority of the multiple people) is not in a state of high mood (i.e., high activity state) and is not in a state of feeling open (i.e., high activity state), the device control system of variant example 2 controls the action of the device 30 so that the state of the multiple people in the target area 60 approaches the target state. Specifically, the device control system of variant example 2 releases refreshing aroma (e.g., aroma with a cool feeling, aroma with a stimulating feeling, or aromas of both) from an aroma diffuser toward the multiple people in the target area 60, and uses any device among a blower, a humidifier, and an air conditioner to flow an airflow with a comfortable humidity and a low temperature that can feel cool, or both, toward the multiple people in the target area 60, so that the activity can be expected to be spent in a more pleasant mood.

[0091] As described above, according to the device control system of the second variant of the first embodiment, by providing a stimulus for bringing the state of the unspecified majority of people located in the target area 60 as a public place (e.g., a state of low activity) close to the target state (e.g., a state of high activity), it is possible to make the people in the target area 60 feel more cheerful. In addition, according to the device control system of the second variant of the first embodiment, by controlling the stimulus for bringing the state of the unspecified majority of people located in the target area 60 as a public place (e.g., a state of high activity) close to the target state (e.g., a state of low activity) (e.g., control of changing or stopping the type of fragrance provided, control of weakening or stopping the airflow provided, or control of both the fragrance and the airflow), it is possible to make the people in the target area 60 feel more cheerful.

[0092] 《1-6》Variant 3

[0093] In the above-mentioned embodiment 1 and variants 1 and 2 of the above-mentioned embodiment 1, in order to reduce the activity of multiple people in the target area 60, lighting equipment, video equipment and air conditioning can also be used to reproduce a quiet and warm scene. For example, it is said that people feel calm near a campfire. Therefore, the device control system of variant 3 of embodiment 1 can make people feel the environment near the campfire by combining two or more of the sound of the campfire emitted by the speaker, the light swaying by the simulated campfire projected by the lighting equipment, the warm air sent from the air conditioner, and the fragrance released from the aromatherapy machine, so as to effectively suppress the activity of people. That is, although it is difficult to simulate such an environment by controlling one device, by controlling multiple devices in combination to simulate a specific environment, it is possible to effectively calm people in an excited state (i.e., people whose activity is above a threshold).

[0094] 《1-7》Variant 4

[0095] In the above-mentioned first embodiment and the first to third variations of the first embodiment, it is also possible to use lighting equipment, video equipment, and air conditioners to reproduce a quiet and cool scene so as to reduce the activity of multiple people in the target area 60. For example, it is said that people feel healed and calm in an environment with water flow, such as near a waterfall or a fountain. The device control system of the fourth variation of the first embodiment can make people feel an environment near water (for example, an environment near a waterfall, an environment with a fountain, an environment with a stream, an environment when it rains, an environment with the sound of waves on the coast, etc.) by combining two or more of the sound of water emitted by a speaker, the cool air adjusted to a suitable humidity sent from the air conditioner, and the blue light projected from the lighting equipment, and can effectively suppress the activity of people. That is, although it is difficult to simulate such an environment by controlling one device, by controlling multiple devices in combination to simulate a specific environment, it is possible to effectively calm people in an excited state (that is, people whose activity is too high to exceed a threshold).

[0096] 《1-8》Variant 5

[0097] In the above-mentioned Embodiment 1 and Variations 1 to 4 of Embodiment 1, the following case is described: the activity level of a representative of a smaller number of people among a plurality of people may be used as the activity level of a plurality of people in the target area 60. In Variation 5 of Embodiment 1, the case is described in which, as the representative, control needs to be performed corresponding to a predetermined person among a plurality of people (for example, a person whose body information is preferably detected preferentially based on gender, whether the person is a child or an adult, whether the person is an elderly person among adults, estimated height, body shape, clothing, the amount of items held, the type of items held, etc.), that is, a person with a high priority, as the representative.

[0098] The device control system of variant example 5 detects a person who is in poor physical condition or in a bad mood among multiple people in the target area 60 based on sound or action, and sets the detected person as a person with a high priority for monitoring. This means that such a person with a high priority is sometimes likely to affect the people around him, causing the physical condition of the people around him to be poor or the mood of the people around him to be bad. For example, the poor physical condition of one person among multiple people or the unhappy mental state of one person may spread to the surroundings, causing the physical condition or mental state of many people in the target area 60 to deteriorate, resulting in a worsening of the atmosphere in the target area 60. In order to prevent such a situation, the device control system of variant example 5 determines the person who is considered to be in the worst physical condition or in the worst mood among multiple people located in the target area 60 based on sound or action, sets the determined person as a person with a high priority, and controls the device to create an environment that enables the person with a high priority to maintain a comfortable physical condition or mental state. As a result, it is expected that the condition of the people located in the place will be improved.

[0099] 《1-9》Variant 6

[0100] In the above-mentioned first embodiment and the first to fifth variations of the first embodiment, the activity of the plurality of persons (or representatives) in the target area 60 is detected mainly based on the voice of the person, the action of the person, or a combination thereof. The device control system of the sixth variation of the first embodiment detects the activity of the plurality of persons (or representatives) in the target area 60 based on the internal body information (e.g., brain wave, heartbeat, body temperature, blood pressure, etc.) as each person's vital sign, the external body information such as posture and movement (e.g., head lowering posture, shaking movement, motionless posture, silent state, direction of sight, etc.), and climate information (e.g., weather, air pressure, etc.), or any combination of the internal body information, external body information, and mechanism information. In addition, the device control system of the sixth variation of the first embodiment detects the situation that the physical state or mental state of the specific person is bad and controls the device, thereby reproducing the environment when the physical state or mental state of the specific person is good. For example, the device control system of variant example 6 can reproduce an environment in which the physical or mental state of a specific person is good by adjusting the temperature and humidity based on air conditioning, adjusting the illumination based on lighting equipment, adjusting the color temperature based on lighting equipment, adjusting the output voice based on audio equipment, adjusting the display image based on imaging equipment, or a combination of these adjustments.

[0101] 《1-10》Variant 7

[0102] In the above-mentioned first embodiment and the first to sixth variations of the first embodiment, various devices are controlled to generate an environment that makes the physical state or mental state of a specific person good, thereby controlling the activity of the person in the target area 60. In the seventh variation of the first embodiment, the following example is described: the main reason for the poor physical state or mental state of a person is irregular life, limited going out of the person (the lack of exercise associated with this), lack of sleep, accumulated fatigue, etc. The device control system of the seventh variation of the first embodiment, for example, can estimate the main reason for the poor physical state or mental state of the plurality of people through a prior investigation (for example, a medical examination, a health diagnosis, etc.) when it is possible to grasp the living conditions of a plurality of people in the target area 60 (a case where a plurality of people regularly go to the hospital or work in the hospital, or a case where a plurality of people go to school or work in a school, etc.). In such a case, the device control system of the seventh variation uses a robot, an audio device, and an image device to reproduce the environment where the plurality of people in the target area 60 are located, thereby suppressing the activity of the plurality of people or increasing the activity. The device control system of Modification 7 can reproduce an environment similar to a real indoor environment or outdoor environment by combining the adjustment of the temperature and humidity of the airflow generated by the air conditioner and the adjustment of the illumination and color of the lighting equipment.

[0103] In addition, when the main cause of a person's poor physical or mental state is lack of sleep, accumulated fatigue, etc., the device control system of variant example 7 can provide a sense of rest to people in the target area 60 by adjusting the temperature and humidity of the air flow generated by the air conditioner, reducing the illumination of the lighting equipment, making the lighting color temperature of the lighting equipment close to the warm color temperature, providing music based on audio equipment, providing images based on imaging equipment, or any combination thereof.

[0104] 《2》Implementation Method 2

[0105] Structure of 2-1

[0106] Fig.11 2 is a block diagram schematically showing the structure of the device control system 2 according to the second embodiment. Fig.11 In the Figure 1 Structures that are identical or corresponding to the structures shown are marked with Figure 1 The device control system 2 is different from the device control system 1 of the first embodiment in that the device control device 20 acquires personal characteristic information indicating the attributes of a plurality of persons within the target area 60 .

[0107] Fig.12 2 is a block diagram schematically showing the structure of the device control device 20 according to the second embodiment. Fig.12 In the Figure 2 Structures that are identical or corresponding to the structures shown are marked with Figure 2 The device control device 20 is different from the device control device 10 of the first embodiment in that it has a target acquisition unit 12, an environment information acquisition unit 13, and a personal characteristic acquisition unit 15, and in the control content of the control unit 11a.

[0108] The personal characteristic acquisition unit 15 acquires characteristic information (also referred to as "character information") that determines the personality of the individual. The personal characteristics are, for example, the Big Five personality characteristics. The Big Five personality characteristics are also called the 5-factor model, which represents the personality (individuality) with five parameters: openness, diligence, extroversion, coordination, and emotional stability. That is, the characteristic information can be included in any element of the five parameters. The Big Five personality characteristics are described, for example, in Non-Patent Document 1.

[0109] Non-patent literature 1: Oliver P.John, Laura P.Naumann, and Christopher J.Soto, "Paradigmshift to the integrative big five trait taxonomy: History, measurement, and conceptual issues", Handbook offpersonality: Theory andresearch, 3.2edition, Guilford Press, (2008), pp.114-158

[0110] Openness indicates the degree to which one likes new experiences or diversity, and can also be called openness to experience. Diligence indicates the degree to which one is motivated and achievement-seeking or prefers planned actions, and can also be called honesty. Extraversion indicates the degree to which one likes to socialize or talk with others. Coordination indicates the degree to which one is cooperative with others, and can also be called agreeableness or attachment. Emotional instability indicates the degree to which one is stable in character and is not prone to unpleasant emotions, and can also be called neuroticism in its opposite meaning.

[0111] In addition, the personality information may include, for example, a parameter indicating the strength of self-control as an element. Self-control is described in Non-Patent Document 2, for example.

[0112] Non-patent literature 2: June P. Tangney, Roy F. Baumeister, and Angie Luzio Boone, "HighSelf-Control Predicts Good Adjustment, Less Pathology, Better Grades, and Interpersonal Success", Journal of Personality 72: 2, (2004), pp.271-324

[0113] Self-control means pursuing desired actions according to one's own will and restraining undesirable actions when facing temptation or impulse. In addition, the personality information may also include other parameters whose definitions and measurement methods are established in the field of psychology. In addition, when there are multiple people using the device 30, it is preferred to have personality information of these multiple people.

[0114] Furthermore, the personal characteristic acquisition unit 15 may acquire personality information obtained by, for example, conducting a personality-related questionnaire survey on a person. The questionnaire survey may be conducted using the input unit 106 or face-to-face when the device 30 is purchased. The personal characteristic acquisition unit 15 may acquire the scores of the personality scale that have been measured through the communication unit 105 via a network or the like, or may acquire the scores of the personality scale that have been measured through human input.

[0115] In addition, personality information may be estimated based on operation history or input history of a button-type interface such as an "Awesome!" button in an SNS (Social Network Service) via a network, etc. Such a method of acquiring personality information is described in Non-Patent Document 3, for example.

[0116] Non-patent literature 3: Wu Youyou, Michal Kosinski, and David Stillwell, “Computer-based personality judgments are more accurate than those made by humans”, Proceedings of the National Academy of Sciences 112.4(2015), pp.1036-1040

[0117] In addition, the personality information may be acquired through a network, etc., and the personality information may be estimated based on the operation history, action history, or stored content of a device such as a smartphone. Such an estimation method is described in Non-Patent Document 4, for example.

[0118] Non-patent literature 4: Clemens Stachl et al. "Predicting personality from patterns of behavior collected with smartphones", Proceedings of the National Academy of Sciences 117.30 (2020), pp.17680-17687

[0119] In addition, the device used when acquiring the personality information may be the same device as the wearable device or non-contact life sensor connected to the body state information acquisition unit 14, or may be another device.

[0120] The control unit 11a determines the personal characteristics based on the personality information acquired by the personal characteristics acquisition unit 15. The control unit 11a may determine the personality information based on the device operation and the device operation history. The personality information is estimated based on the device operation using the correlation between the Big Five personality characteristics of the personality information and the device operation preference. An example is described below.

[0121] Fig.13 2 is a diagram showing an example of the correlation between the Big Five personality traits and the operation of home appliances. Fig.13 An example of the correlation between the operation or action history of household appliances such as air conditioners, heat pump water heaters used for bathing, refrigerators, etc. and the Big Five personality traits is shown. There is a positive or negative correlation between the Big Five personality traits and the operation of the appliance, so personality information can be estimated based on the operation or action history of the appliance.

[0122] For example, Fig.13 The following examples (G1) to (G8) are shown in table format.

[0123] (G1) There is a strong negative correlation between the person (g1) who frequently sets the temperature of the air conditioner and the coordination.

[0124] (G2) There is a strong positive correlation between people (g2) who use the automatic setting as the temperature setting of the air conditioner and openness (i.e., a personality that is easily receptive to new functions), a negative correlation between people (g2) and emotional instability (i.e., a personality that is sensitive to changes in temperature), and a positive correlation between people (g2) and extraversion.

[0125] (G3) There is a strong positive correlation between people who prefer automatic control of air conditioning (g3) and emotional instability.

[0126] (G4) There is a positive correlation between the person (g4) who changes the air direction of the air conditioner frequently and openness, and there is a negative correlation between the person (g4) and coordination.

[0127] (G5) There is a strong positive correlation between (g5) and openness among people who take a long bath, and a positive correlation between (g5) and extraversion.

[0128] (G6) There is a strong positive correlation between (g6) and openness among people who take a bath more often, and there is a positive correlation between (g6) and extraversion.

[0129] (G7) There is a strong positive correlation between people (g7) who frequently open the vegetable compartment of the refrigerator and extraversion, a strong positive correlation between people (g7) and openness, a positive correlation between people (g7) and diligence, and a weak negative correlation between people (g7) and emotional instability.

[0130] (G8) There is a weak positive correlation between (g8) and extraversion, a weak positive correlation between (g8) and openness, and a positive correlation between (g8) and diligence.

[0131] When calculating the current value of the activity of the party participant's action, the control unit 11a performs corrections according to the personality information obtained by the personal characteristic acquisition unit 15. For example, a person with high coordination tends to act in coordination with others, and therefore, the activity of the action is not easy to change. A person with high extroversion tends to show a large change in the activity of the action. A person with high emotional instability tends to change the activity of the action easily.

[0132] The control unit 11a performs correction based on the personality information when determining the target value of activity. The target value of the activity of the overall action is adjusted according to the individual characteristics of the multiple people located in the target area 60. For example, when there are many people with high coordination (i.e., people with small changes in activity) among the party participants, the control unit 11a adjusts and sets the target value of activity to a larger value. In addition, when there are many people with high extroversion (i.e., people with large changes in activity) among the party participants, the control unit 11a adjusts and sets the target value of activity to a lower value. In addition, when there are many people with high emotional instability (i.e., people with drastic changes in activity) among the party participants, the control unit 11a adjusts and sets the target value of activity to a value close to the current value of activity.

[0133] 2-2 Action

[0134] Fig.14 1 is a flowchart showing the calculation of personal characteristics of the device control device 20 according to Embodiment 2. First, the control unit 11a obtains the attributes related to the person and the physical quantity detected from the person, that is, the person detection value, as the person information via the body state information acquisition unit 14 and the communication unit 105 (step S41). The obtained person information is provided to the personal characteristics acquisition unit 15. In addition, the device operation mode of the scheduled party attendees stored in the storage unit 103 is called (step S42).

[0135] The control unit 11a calculates personal characteristics based on the attributes from the body condition information acquisition unit 14 or based on the device operation mode (step S43).

[0136] Fig.15This is a flowchart showing the processing of the equipment control device 20 according to the second embodiment. First, the control unit 11a obtains target information A0 (for example, target value A1) indicating the target state of the actions of multiple people located in the target area 60 via the target acquisition unit 12 (step S41). Next, the control unit 11a obtains environmental information B0 (including mechanical state information) indicating the state of the environment of the target area 60 where the multiple people are located from the environmental information acquisition unit 13 (step S42). Next, the control unit 11a obtains body state information C0 indicating the body states of the multiple people from the body state information acquisition unit 14 (step S43). Next, the control unit 11a obtains personal characteristics D0 indicating the personality information of the multiple people from the personal characteristics acquisition unit 15, and adjusts the target value A1 of the activity level according to the personal characteristics D0 (step S44). In addition, the order of steps S41 to S44 is not limited to Fig.14 The order shown may also be other orders.

[0137] Next, the control unit 11a calculates the current value A2 of the activity level based on the physical state information C0. Next, the control unit 11a controls the device 30 so as to create an environment in which the current value A2 of the activity level approaches the adjusted target value A1.

[0138] 《2-3》Effect

[0139] As described above, according to Embodiment 2, the states of the plurality of persons in the target area 60 can be brought closer to the target state with higher accuracy. For example, by dynamically changing the target value of activity according to individual characteristics, the device 30 can be controlled so that when the activity of the party participants is too high and the discussion is too intense, the activity is reduced (i.e., calmed down), or when the party is too quiet, the activity is increased (i.e., activated).
