1 is a block diagram illustrating a first embodiment. FIG. 3 is an operation explanatory diagram of the first embodiment. FIG. 6 is a block diagram illustrating a second embodiment. FIG. 6 is a block diagram illustrating a third embodiment.

  An environment control device described below is used to control the environment of a work space in a space (hereinafter referred to as “work space”) in which a work in which a mental work-load occurs is performed. This environment control device has a function of controlling the operation of equipment that affects the environment of the work space so as to suppress a decrease in the concentration of workers. The environment control device desirably has a function of controlling the operation of the device so as to form an environment in which workability is enhanced.

  The work performed by the worker is assumed to be a cognitive work and a mental work in a narrow sense, but may be a work mainly based on physical load. This type of work includes learning, VDT work (VDT: Visual Display Terminals), video conferencing, surveillance work, reading and the like. Furthermore, learning is subdivided into lessons, memorization, proficiency tests, and the like. The lesson may be video learning (for example, e-learning) performed by viewing a video image using a display device. The VDT work assumes a work selected from sentence creation, data aggregation, presentation material creation, and the like.

  The work space is generally an indoor space. Moreover, although the case where an apparatus is comprised so that the environment with respect to one worker may be formed as an example is demonstrated, even if it is a case where a common environment is formed with respect to a plurality of workers, It is possible to apply the techniques described.

  In general, while the worker performs the above-described work, the mental work load is reduced. Decreasing effects of mental workload include mental fatigue, fatigue-like state, monotony, reduced attention, mental saturation, etc. (see ISO10075). In this embodiment, this type of reducing effect is This is called a decrease in concentration. That is, the degree of concentration is an index of the degree of the deteriorating effect on the mental workload, and the smaller the index, the greater the deteriorating effect.

  Even if the workers are the same, even if the contents of the work are the same, the degree of the mental work load is different, and the manner of changing the degree of concentration with time is often different. In other words, the way of changing the concentration varies depending on the characteristics of the worker. In addition, the concentration level of one worker varies depending on factors such as the content of the work, the physical condition of the worker, and the environment of the work space.

  The environment control apparatus according to the present embodiment acquires information related to the concentration level of the worker over time in order to suppress a decrease in the concentration level of the worker. It is known that changes in the concentration of workers appear in brain activity and movement. The movement here may be movement of the upper body or hand, movement of the face, movement of the eyelid, and the like. For facial movements, changes in facial expressions can be used as information relating to the degree of concentration, and for eyelid movements, the number of blinks per unit time can be used as information relating to the degree of concentration.

  Further, the degree of concentration in the VDT work can be said to be reflected in the time required for the work element if the operation of the terminal device by the operator is classified for each work element and attention is paid to a specific work element. For example, when entering text, focusing on pressing a key on the keyboard as a specific work element, the concentration of the operator is reflected in the average value of the number of key presses (number of keystrokes) per minute. Is done. The environmental control device acquires information on the concentration level using the output of the sensor that monitors the event selected from these groups.

  Regarding the brain activity of the worker, a sensor is known that is attached to the worker's head and monitors changes in the blood flow of the brain using near infrared rays. This sensor can monitor brain activity non-invasively and lightly. For the movement of the upper body or hand, the change in facial expression, and the number of blinks, a technique of extracting a feature amount from an image captured by the camera using a camera that captures the worker as a sensor is employed. It is desirable that the camera captures a moving image of about 15 to 60 frames per second. However, the camera may be configured to take still images at intervals of about one per second.

  The quantification of the concentration level of the worker may be performed by paying attention to the direction of the line of sight of the worker who is performing the VDT work. That is, the direction of the operator's line of sight may be extracted by photographing a range including the eyeball of the worker using a camera, and the degree of concentration may be quantified based on a change in the direction of the line of sight with time. In this case, in a unit time, it is possible to evaluate that the degree of concentration is higher as the period during which the change in the direction of the line of sight is within the range of the screen of the terminal device is longer. Also, when shooting a range including the eyeball of the worker using a camera, the screen of the terminal device, which is a reflection image of the surface of the eyeball of the worker, is collated with the screen of the actual terminal device, and in unit time It may be evaluated that the longer the time in which both are overlapped, the higher the degree of concentration.

  In this case, the camera may be in the form of being built in or externally adjacent to the display of the terminal device so as to face the worker. However, as described above, particularly when the operator's eyes are photographed, it is desirable that the camera is of a spectacle type and is attached to a frame attached to the operator's head. In addition, a display device for displaying the screen of the terminal device may be attached to the frame. That is, the terminal device may include a head mounted display, and the camera as the sensor 20 may be provided on the head mounted display.

  The manner in which the degree of concentration changes depends on the characteristics of the worker, and the degree of concentration also changes for the same worker depending on the work content, the physical condition of the worker, the environment of the work space, and the like. In the present embodiment, the characteristics of the worker and the physical condition of the worker are not particularly taken into consideration, and the environment control device determines whether the work space is based on the change in the relative concentration of the worker over time and the work content. A technology for controlling the environment will be described.

  The environment control apparatus described below includes a processor that operates according to a program, a memory, and a device that constitutes an interface for connecting an external apparatus as main hardware elements. The processor is selected from a microcomputer having a processor and a memory integrally, an MPU (Micro-Processing Unit) to which the memory is separately connected, and the like. Therefore, the environment control device can be realized by a personal computer, a HEMS (Home Energy Management System) controller, a smartphone, a tablet terminal, or the like in addition to the dedicated device. In particular, since the HEMS controller can control and monitor various devices, it can be used as an environment control device described below simply by providing a program. Each of these is a kind of computer and includes a built-in clock such as a real time clock.

  The program may be provided by a ROM (Read Only Memory) built in the computer, but may be provided by a computer-readable recording medium (CD-ROM, memory card, etc.) in preparation for upgrading. desirable. The program may be provided through a telecommunication line such as the Internet.

  As shown in FIG. 1, the environment control apparatus 10 includes an interface unit (hereinafter referred to as “I / F unit”) 11 to which a sensor 20 that monitors an event related to the degree of concentration of the worker is connected. The number of sensors 20 is not limited to one, and a plurality of sensors 20 may be provided. The I / F unit 11 passes the output of the sensor 20 to the determination unit 12. The determination unit 12 extracts information related to the concentration level of the worker from the output of the sensor 20, and obtains an evaluation value of the concentration level based on this information.

  For example, when the sensor 20 that monitors the brain activity is used, the determination unit 12 extracts the part where the brain activity is activated and the degree of activation as information related to the degree of concentration, and is determined in advance. The evaluation value of the degree of concentration is obtained by collating with the data table. When the sensor 20 is a camera, the determination unit 12 sets a plurality of feature points on the worker's face and compares the distance ratio between the feature points with a predetermined data table to express the facial expression. Further, the evaluation value of the degree of concentration is obtained from the change in facial expression. When an image including the eyes of the worker is taken with a camera, it is possible to obtain an evaluation value of the degree of concentration by extracting eyelid movement from the image and counting the number of blinks. When the worker performs the VDT work, as described above, the determination unit 12 pays attention to a specific work element, and obtains the evaluation value of the degree of concentration using the time required for the focused work element.

  As for the work content, when the sensor 20 is a camera, the determination unit 12 detects the movement of the worker in the image captured by the camera, the article existing within a predetermined distance range from the worker in the image, and the like. The contents of the work performed by the worker are estimated. When the worker is performing the VDT work, the determination unit 12 estimates the work content according to the type of application program used by the worker. The work contents may be reported through an input device (not shown) that gives information to the environment control device 10. This type of input device may be a device selected from a smartphone, a tablet terminal, a personal computer, or the like in addition to the dedicated device of the environment control device 10. Moreover, the work content performed for every time slot | zone may be defined beforehand as a schedule, and the determination part 12 may determine work content according to a schedule.

  In the example described above, the determination unit 12 extracts information related to the degree of concentration based on the output of one type of sensor 20, but by combining the outputs of a plurality of types of sensors 20, the determination unit 12 relates to the degree of concentration. Information may be extracted.

  Information related to the evaluation value of the degree of concentration and information related to the work content obtained by the determination unit 12 are collated by the determination unit 13 with data stored in the control information storage unit 14. The control information storage unit 14 stores in advance data in which a set of the work content and the evaluation value of the degree of concentration is associated with the operating state of the device 30 that affects the environment. Therefore, when the determination unit 13 collates the information regarding the work content and the information regarding the evaluation value of the degree of concentration with the data stored in the control information storage unit 14, the operation state of the device 30 is extracted from the control information storage unit 14. Is done. The determination unit 13 delivers the operation state of the device 30 extracted from the control information storage unit 14 to the device control unit 15.

  The control information storage unit 14 divides the evaluation value of the degree of concentration into a plurality of stages for each work content, and associates the type of the device 30 that affects the environment with the operation state of the device 30 for each step of the evaluation value. Stored data. Table 1 shows an example of data stored in the control information storage unit 14.

  In Table 1, two types of work contents, “video learning” and “skill level test”, are given as examples, and the evaluation value of the degree of concentration is “high”, “medium”, and “low” for each work content. Classified into stages. Table 1 lists three types of devices 30 that affect the environment: “ventilation fan”, “air conditioner”, and “lighting” in both “video learning” and “skill proficiency test”. Furthermore, in Table 1, when the degree of concentration is “medium” in “video learning” as the operation state of the device 30, “weak” is specified for the ventilation fan, “blow” is specified for the air conditioner, and “video learning” is the concentration. When the degree is “low”, “strong” is designated for the ventilation fan, “cooling” is designated for the air conditioner, and “off” is designated for the lighting. In addition, when the concentration level is “medium” in the “skill proficiency test”, “weak” is specified for the ventilation fan, “silent ventilation” is specified for the air conditioner, and when the concentration level is “low” in the “skill level test”, Specify "strong" for the ventilation fan, "silent cooling" for the air conditioner, and "spot lighting" for the lighting.

  Table 1 is an example, and all of the work content, the number of stages of concentration, the type of the device 30, and the operating state of the device 30 are appropriately changed according to the purpose of suppressing the decrease in the concentration of the worker. It is possible. For example, with respect to the type of the device 30, not all the devices 30 shown in Table 1 are usable, and the usable device 30 may be selected. In addition, if the device 30 that blows air is necessary as in the case where the degree of concentration is “medium”, a fan or a circulator can be used as the device 30 instead of the air conditioner. That is, the device 30 can be replaced as necessary, and another device 30 may be used in addition to the device 30 shown in Table 1. Further, the operating state of the device 30 can be changed as appropriate.

  The type of the device 30 and the operation state of the device 30 extracted by the determination unit 13 from the control information storage unit 14 are input to the device control unit 15. The device control unit 15 can communicate with the device 30 that affects the environment, and can instruct the operating state of the device 30 by transmitting a command to the device 30. That is, the device control unit 15 notifies the device 30 extracted by the determination unit 13 of a command corresponding to the operation state extracted by the determination unit 13.

  FIG. 2 briefly shows the operation of the environment control apparatus 10 described above. When the work content and the information related to the concentration level are input from the sensor 20 or the terminal device 21 to the determination unit 12 (P1), the determination unit 12 obtains the evaluation value of the concentration level using the information related to the concentration level (P2). The evaluation value of the degree of concentration is sent to the determination unit 13 together with the work content (P3). The determination unit 13 compares the type of the device 30 and the operation state of the device 30 in order to improve the evaluation value of the concentration level by collating with the control information storage unit 14 when the evaluation value of the concentration level decreases. Extract. The type of the extracted device 30 and the operating state of the device 30 are sent to the device control unit 15 (P4), and the device control unit 15 notifies the device 30 designated by the determination unit 13 from the determination unit 13. A command for instructing the operated state is notified (P5). As described above, it is possible to control the environment of the work space and to maintain or improve the concentration of workers.

  According to the above-described configuration, when the evaluation value of the operator's concentration level decreases from “high” to “medium” or “low”, the required device 30 is required according to the work content and the evaluation value of the concentration level. The command of the operation state is transmitted. The control information storage unit 14 stores data defining the type of the device 30 to be operated and the operating state of the device 30 according to the work content and the evaluation value of the concentration level so as to improve the concentration level of the worker. ing. Therefore, when the operator's concentration level decreases, the device 30 is controlled to increase the operator's concentration level, and as a result, the worker's concentration level is maintained at a relatively high level. That is, a decrease in work efficiency due to a decrease in concentration is suppressed.

  Now, assume that the worker's concentration evaluation value obtained by the determination unit 12 changes from “high” to “medium” when the worker is performing video learning while heating by the air conditioner. In this case, since the carbon dioxide concentration in the work space is reduced by operating the ventilation fan at “weak”, the decrease in the concentration due to the increase in the carbon dioxide concentration is suppressed. In addition, the air conditioner switches from heating operation to air blowing operation, and air temperature is formed around the worker, so the temperature of the sensation decreases, and the temperature of the work space decreases when the heating stops. Contribute to.

  The period during which the device 30 is operated to increase the concentration level when the evaluation value of the operator's concentration level decreases is appropriately determined. For example, this period is a period until the evaluation value of the concentration level recovers, a fixed time (for example, 5 to 10 minutes) after the evaluation value of the concentration degree is recovered, and is constant regardless of the change in the concentration level. It is selected from time (for example, 30 minutes).

  In the configuration example described above, when the determination unit 12 obtains the evaluation value of the degree of concentration using the output of the sensor 20, information related to the work content and the degree of concentration obtained from the terminal device 21 (for example, the number of keystrokes) The case where the evaluation value of the degree of concentration is obtained using and is exemplified. Here, the terminal device 21 does not have to be directly connected to the I / F unit 11, and the I / F unit 11 may be connected to an electric communication line 22 such as the Internet or a LAN (Local Area Network). . That is, the I / F unit 11 and the terminal device 21 may communicate with each other through the telecommunication line 22. In this case, a server device 23 that transfers information related to work content and concentration between the terminal device 21 and the environment control device 10 may be connected to the telecommunication line 22. The server device 23 has a function as a server for work performed by the worker using the terminal device 21, and may have a function of processing information acquired from the terminal device 21 and delivering it to the environment control device 10. . Note that the number of terminal devices 21 is not limited to one, and a plurality of terminal devices 21 may be provided.

  When the terminal device 21 is equipped with the camera 211, the camera 211 of the terminal device 21 may be used as a camera as the sensor 20. That is, a worker who performs VDT work by the terminal device 21 may be imaged by the camera 211, and work contents that can be understood from the application program being used and an image of the camera 211 may be given to the environment control device 10. In this configuration, the determination unit 12 determines the concentration level of the worker using an image acquired from the camera 211. Note that an electric communication line 22 may exist between the terminal device 21 and the environment control device 10. Information may be passed between the terminal device 21 and the environment control device 10 through the server device 23.

  As described above, the environment control apparatus 10 according to the present embodiment includes the determination unit 12, the determination unit 13, the control information storage unit 14, and the device control unit 15. The device control unit 15 instructs the operation state of the device 30 that affects the environment of the work space. The determination unit 12 obtains an evaluation value of the degree of concentration using information related to the work content performed by the worker in the work space and the degree of concentration of the worker. In the control information storage unit 14, the device 30 contributing to the improvement of the degree of concentration and the operation state of the device 30 are associated with each work content. When the evaluation value of the degree of concentration obtained by the determination unit 12 decreases, the determination unit 13 extracts the device 30 corresponding to the work content received from the determination unit 12 and the operation state of the device 30 from the control information storage unit 14, The extracted device 30 and the operation state are delivered to the device control unit 15.

  According to this configuration, when the concentration level of the worker is lowered, the device 30 is controlled so as to recover the concentration level of the worker. Therefore, the worker can maintain or improve the concentration level. Become. As a result, the work can be performed without lowering the efficiency during the work. For example, when the work is learning and the worker's concentration is reduced during the period when heating is performed by the air conditioner as the device 30, the operation state of the work space is changed by switching the operation state of the air conditioner from heating to blowing. The temperature can be reduced, and the decrease in the concentration of workers can be suppressed. In addition, in order to suppress a decrease in the concentration of workers, the brightness of the equipment is increased and the illuminance at the place where the worker is working is also increased, thereby suppressing the decrease in the concentration of workers. it can. In addition, the environment control apparatus 10 may control the driving | running state of an air conditioner, and the brightness | luminance of illumination collectively.

  The determination unit 12 may receive work content from the terminal device 21 operated by the worker. Further, the determination unit 12 receives time required for a specific work element in the work content from the terminal device 21 as information related to the concentration level of the worker, and obtains an evaluation value of the concentration level of the worker using the time. You may do it.

  In this configuration, since the work content and the information related to the concentration level are acquired from the terminal device 21 where the worker is actually working, accurate information regarding the work content and the concentration level can be obtained. In other words, it becomes possible to accurately grasp the change in the concentration level of the worker and appropriately control the equipment in order to maintain or improve the concentration level.

The determination unit 12 receives work content from the server device 23 that communicates with the terminal device 21 operated by the worker. Further, the determination unit 12 receives time required for a specific work element in the work content from the server device 23 as information related to the concentration level of the worker, and obtains an evaluation value of the concentration level of the worker using the time. According to this configuration, since information related to the work content and the degree of concentration is obtained from the terminal device 21 where the worker is actually working through the server device 23, accurate information regarding the work content and the degree of concentration is obtained. Can be obtained. In addition, since the information is acquired from the terminal device 21 via the server device 23, if the information is processed by the server device 23, the processing load on the environment control device 10 is reduced.

  The determination unit 12 may be configured to extract the movement of the worker from the video of the camera that shoots the worker and obtain the evaluation value of the degree of concentration using the extracted movement.

  According to this configuration, information selected from the movement of the worker, that is, the movement of the worker's upper body or hand, the change in facial expression, the number of blinks, and the like is extracted from the video captured by the camera and is extracted from the video. The degree of concentration is evaluated based on the extracted information on the movement of the worker. Therefore, it is possible to obtain an evaluation value of the operator's concentration level in various operations.

  The determination unit 12 receives the work content from the terminal device 21 operated by the worker, and as the information related to the concentration level of the worker, the range including the display content of the screen of the terminal device 21 and the eyeball of the worker. You may receive the reflected image of the eyeball surface contained in the image | video of the camera to image | photograph. In this case, the determination unit 12 obtains the evaluation value of the degree of concentration using the time when the reflected image overlaps the display content of the screen of the terminal device 21.

  In this configuration, the frequency (time per unit time) of the reflected image of the eyeball surface and the display content of the screen of the terminal device 21 is high. This is because the frequency of the operator watching the screen of the terminal device 21 is high. Judgment can be made. Therefore, it is possible to evaluate that the degree of concentration is high when the reflection image and the display content of the screen of the terminal device 21 are frequently overlapped.

  In the present embodiment, the determination unit 12 obtains the work content and the evaluation value of the concentration level using information related to the work content performed by the worker in the work space and the concentration level of the worker. When the evaluation value of the degree of concentration obtained by the determination unit 12 decreases, for the device 30 that affects the environment of the work space, the work content received from the determination unit 12 as the predetermined device 30 and the operating state of the device 30 Is determined by the determination unit 13. The device 30 and the operating state of the device 30 are determined so as to improve the evaluation value of the degree of concentration with respect to the work content. Furthermore, the operation state is instructed from the device control unit 15 to the device 30 determined by the determination unit 13.

  According to this method, when the concentration level of the worker is lowered, an instruction is given to the device 30 so as to maintain or improve the concentration level of the worker. Therefore, the worker can maintain or improve the degree of concentration and can continue the work without reducing the efficiency.

(Embodiment 2)
As shown in FIG. 3, the environment control apparatus 10 of the present embodiment is different from the first embodiment in that a reference environment storage unit 16 in which an appropriate environment range is set for each work content is added. The reference environment storage unit 16 stores an appropriate range for each work content regarding environmental elements such as temperature, humidity, wind speed, illuminance, and carbon dioxide concentration. The appropriate range of environmental elements according to the work content is set using various data because various data have been published. For example, the illuminance corresponding to the work content is shown in Japanese Industrial Standards.

  In the present embodiment, the determination unit 13 compares the work content and the evaluation value of the concentration degree with the control information storage unit 14 and the reference environment storage unit 16. Then, the determination unit 13 extracts the type and operation state of the device 30 from the control information storage unit 14 and extracts an appropriate range of environmental elements according to the work content from the reference environment storage unit 16. Here, when the evaluation value of the degree of concentration decreases (for example, when it decreases from “high” to “medium” or “low”), the type and operating state of the device 30 are read from the control information storage unit 14. The device control unit 15 instructs the required device 30 to operate based on information read from the control information storage unit 14 by the determination unit 13.

  By the way, the data stored in the control information storage unit 14 is the type and operating state of the device 30 corresponding to the work content and the evaluation value of the degree of concentration, and forms an environment according to the work content. The device 30 cannot be instructed to operate. In short, the data in the control information storage unit 14 is set so as to temporarily shift the device 30 to an operation state different from normal in order to improve the degree of concentration of workers.

  On the other hand, the work space must normally be maintained in an environment suitable for the work content. Therefore, the reference environment storage unit 16 stores an appropriate range of environmental elements according to the work content. When the evaluation value of the degree of concentration by the determination unit 12 is high (for example, “high”), the determination unit 13 maintains an appropriate range of environmental elements read from the reference environment storage unit 16 according to the work content. As described above, the command is transmitted to the device 30 through the device control unit 15. By this operation, an environment of a work space suitable for the work content is realized, and the worker can work in an appropriate environment.

  For example, when the work content is learning, appropriate ranges of temperature, humidity, and illuminance corresponding to the type of learning are set in the reference environment storage unit 16. The device control unit 15 uses the data read from the reference environment storage unit 16 so that the environment of the temperature, humidity, and illuminance of the work space is controlled to an appropriate range according to the type of learning. Give instructions to. Accordingly, it is possible to improve the learning efficiency of the worker.

  In the reference environment storage unit 16, an appropriate range for each environmental element according to the work content may be set by being divided into appropriate periods. In the reference environment storage unit 16, an appropriate range for each environmental element corresponding to the work content may be set for each worker. Of course, the appropriate range may be classified by a combination of a period and an operator. Moreover, you may classify according to the attribute thru | or characteristic (hot, cold, etc.) with respect to an operator's environment instead of an individual worker.

  The period is selected from the period specified by the season and date, day of the week, time zone, and the like. That is, it is desirable to determine an appropriate range of environmental elements for each period so as to match changes in the characteristics of the worker according to the period, such as worker motivation, circadian rhythm, and acclimatization to the thermal environment. When the appropriate range of the environmental element is classified according to the period, the determination unit 13 determines whether or not the date and time measured by the internal clock (not shown) is the period stored in the reference environment storage unit 16. to decide. If the period is suitable, the determination unit 13 transmits a command to the device 30 through the device control unit 15 so that the environmental element in the work space falls within an appropriate range stored in the reference environment storage unit 16.

  On the other hand, when the appropriate range of the environmental element is classified for each worker (or for each characteristic of the worker), the determination unit 13 extracts the appropriate range of the environmental element corresponding to the worker from the reference environment storage unit 16. To do. Here, in order to specify the worker, if the worker's face is photographed by the camera, the face authentication may be performed based on the image photographed by the camera. In addition, more simply, when the worker starts work, a configuration may be used in which an input device (not shown) is used for reporting. In the case of work using the terminal device 21, an operator is assigned to each terminal device 21 in advance, and the worker is specified by the terminal device 21, or the worker is notified through the terminal device 21. Good.

  In addition to the environment control device 10 described in the first embodiment, the environment control device 10 according to the present embodiment further includes a reference environment storage unit 16 in which an appropriate range according to the type of work content is set for the environmental elements of the work space. Prepare. In this configuration, the determination unit 13 collates the work content received from the determination unit 12 with the reference environment storage unit 16 and extracts an appropriate range of environmental elements according to the work content. The device control unit 15 transmits a command to the device 30 so that the appropriate range of the environmental elements extracted by the determination unit 13 is maintained.

  According to this configuration, an optimal space environment based on an environmental element corresponding to the time is realized, so that the worker can perform work more efficiently and effectively.

  In the reference environment storage unit 16, it is desirable that the appropriate range of environmental elements is set by classification for each period in addition to the type of work content. In this configuration, the determination unit 13 preferably collates the work content received from the determination unit 12 with the reference environment storage unit 16 and extracts an appropriate range of environmental elements according to the work content in the period to which the collation time belongs. .

  According to this configuration, by setting an appropriate range of the environment of the work space for each period such as a time zone, day of the week, and season, an appropriate environment that follows changes in the characteristics of the worker for each period Can be formed.

  In the reference environment storage unit 16, it is desirable that the appropriate range of the environmental elements is set for each worker in addition to the type of work content. In this configuration, it is preferable that the determination unit 13 collates the work content received from the determination unit 12 with the reference environment storage unit 16 and extracts an appropriate range of environmental elements according to the work content for the worker.

According to this configuration, since an appropriate range is set for the environment of the work space according to the attribute or characteristic of each worker, an environment in which the operator can easily increase the degree of concentration is formed. Other configurations and operations in the present embodiment are the same as those in the first embodiment.
(Embodiment 3)
The configuration example described above assumes a case where the space that forms the environment by the device 30 and the work space substantially coincide. That is, it is assumed that the environment of the entire space is collectively controlled by the device 30. On the other hand, in a relatively large space such as an office space, a work space may be formed in a part of the space, and the device 30 may be arranged so as to form an environment locally for each work space. In this case, the environment is controlled for each work space by the device 30 arranged for each work space.

  In the present embodiment, a configuration in which one environment control device 10 controls the environment of a plurality of work spaces will be described. The work space is not limited to being formed as a part of a wide space, and independent rooms may be used as the work spaces.

  As described above, since the environment control device 10 forms an environment for each work space when there are a plurality of work spaces, the work space where the worker is working is recognized as shown in FIG. In order to do this, a work space determination unit 17 is added. The work space determination unit 17 determines whether or not a person is working in each work space.

  If a person is working in the work space, the determination unit 12 gives the work content and the evaluation value of the degree of concentration to the determination unit 13. Therefore, the work space determination unit 17 needs to specify the work space in which the worker exists and specify the worker.

  In order to specify the work space where the worker exists, for example, a human sensor having the work space as a monitoring area may be used. Further, as described in the first embodiment, a technique selected from a report by the worker, face authentication based on an image photographed by a camera, or the like is used for specifying the worker. When the camera is used, the work space determination unit 17 can specify not only the worker but also the work space based on the image captured by the camera.

  When the work space determination unit 17 passes the information on the work space and the information on the worker to the determination unit 13, the determination unit 13 receives the work content and the evaluation value of the degree of concentration from the determination unit 12 and stores them in the control information storage unit 14. The operating state of the device 30 is determined using the obtained data. When the reference environment storage unit 16 is provided as in the second embodiment, the determination unit 13 extracts an appropriate range of environmental elements from the reference environment storage unit 16.

  When the type of the device 30 and the operating state of the device 30 are determined for the work space being worked, the determination unit 13 gives an instruction to the device 30 through the device control unit 15 so as to control the environment of the corresponding work space. By performing such an operation, the environment control apparatus 10 sets the environment so as to maintain or improve the operator's concentration degree in the environment of the work space where the worker is working among the plurality of work spaces. It becomes possible to control.

  In addition to the configuration of the first or second embodiment, the environment control apparatus 10 of the present embodiment has a work space in which an operator is working when there are a plurality of work spaces in which the devices 30 are arranged. Is further included. In this configuration, the determination unit 13 hands over the operating state of the device 30 arranged in the working space recognized by the work space determination unit 17 to the device control unit 15.

  According to this configuration, even when there are a plurality of work spaces, an appropriate environment according to the work content and the evaluation value of the degree of concentration is realized in the work space where the worker is present. Other configurations and operations in the present embodiment are the same as those in the first or second embodiment.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it can be changed.
