DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the present disclosure, there was a technology for displaying information indicating air quality, such as that disclosed in Patent Document 1. In Patent Document 1, it is not possible to know at a glance whether a circular image is an image that constitutes part of a layout, and it is difficult to know whether a circular image is an image that indicates an air quality state. Furthermore, since Patent Document 1 shows a plurality of types of air quality states using a single circular image, it is difficult to intuitively grasp each of the plurality of types of air quality, and it is difficult to easily grasp an impression of an overall air quality state that takes into account the plurality of types of air quality states. The inventors discovered this problem, and came to constitute the subject of the present disclosure in order to solve this problem. Therefore, the present disclosure provides a display method, a terminal device, a display system, and a program that enable a user to easily grasp multiple types of air quality conditions and visually recognize the overall air quality condition taking into account the multiple air quality conditions.

[0012] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially the same configurations may be omitted. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0013] (Embodiment 1) [1-1. Configuration] [1-1-1. Display system configuration] FIG. 1 is a diagram showing the configuration of a display system 1000. The display system 1000 is a system that enables a terminal device 1 to display the state of air quality in a target space SP. The target space SP is a space in which an air quality sensor 2 detects air quality, and is an internal space of a building H, i.e., indoors.

[0014] FIG. 2 is a diagram showing a schematic view of the target space SP as viewed from above. The target space SP is divided into six areas ER: a first area ER1, a second area ER2, a third area ER3, a fourth area ER4, a fifth area ER5, and a sixth area ER6.

[0015] Each of the first area ER1 to the sixth area ER6 is provided with an air quality sensor 2 and a wind speed sensor 3. The air quality sensor 2 and the wind speed sensor 3 will be described later. Furthermore, an indoor unit 4 is provided in each of the first area ER1, the second area ER2, the fourth area ER4, and the fifth area ER5. Further, in the second area ER2, the third area ER3, the fifth area ER5, and the sixth area ER6, an outlet IH for releasing the hypochlorous acid generated by the first air purification device 5 is provided.

[0016] 1, the display system 1000 includes an air quality sensor 2. The display system 1000 of the present embodiment includes six air quality sensors 2. The air quality sensor 2 is a sensor that detects air quality and is installed in the target space SP. The air quality sensor 2 of this embodiment detects temperature, humidity, CO2 concentration (hereinafter referred to as "CO2 concentration"), PM2.5 concentration (hereinafter referred to as "PM2.5 concentration"), microorganism (e.g., mold and virus) concentration (hereinafter referred to as "microorganism concentration"), and odor as air quality. Therefore, the air quality sensor 2 includes a temperature sensor, a humidity sensor, a CO2 sensor that detects CO2 concentration, a PM2.5 sensor that detects PM2.5 concentration, a microorganism sensor that detects microorganism concentration, and an odor sensor that detects odor. The CO2 sensor is, for example, a sensor that employs a non-dispersive infrared absorption method. The PM2.5 sensor is, for example, an optical sensor that includes a light emitting unit and a light receiving unit. The microorganism sensor is, for example, a respiration measurement type or an electrode active material measurement type sensor. The odor sensor is, for example, a sensor whose sensor element is made of a semiconductor. PM2.5 and microorganisms are examples of "air pollutants."

[0017] When the air quality sensor 2 detects six types of air quality at a predetermined period (for example, five-minute period), it transmits first detection data D1 to the server device 6 each time a detection is made. The first detection data D1 includes a detection value for each of the six types of air quality. A first sensor ID (Identification) for identifying the air quality sensor 2 is added to the first detection data D1. The air quality sensor 2 may communicate with the server device 6 connected to the network NW via a local network constructed in the building H, or may communicate with the server device 6 without going through the local network. The network NW includes the Internet, a telephone network, and other communication networks.

[0018] The display system 1000 includes a wind speed sensor 3. The display system 1000 of the present embodiment includes six wind speed sensors 3. The wind speed sensor 3 is a sensor that detects wind speed and is installed in the target space SP. The wind speed sensor 3 detects wind speed, for example, by temperature changes of a heated element. The wind speed sensor 3 is installed in the vicinity of the air quality sensor 2. For example, the wind speed sensor 3 is installed at a position less than a predetermined distance (for example, 20 centimeters) from the air quality sensor 2 installed in the same area ER. The wind speed sensor 3 detects wind speed at a predetermined period (for example, 5 minutes), and transmits second detection data D2 to the server device 6 every time it detects wind speed. The second detection data D2 includes the detection value of the wind speed sensor 3. The second detection data D2 transmitted to the server device 6 is added with a second sensor ID that identifies the wind speed sensor 3. The wind speed sensor 3 may communicate with the server device 6 connected to the network NW via a local network constructed in the building H, or may communicate with the server device 6 without going through the local network.

[0019] The display system 1000 includes an indoor unit 4. The display system 1000 of the present embodiment includes four indoor units 4. The indoor unit 4, together with an outdoor unit (not shown), constitutes an air conditioning device and conditions the target space SP. In this embodiment, the indoor unit 4 is exemplified as a ceiling cassette type indoor unit, but the indoor unit 4 may be of other types such as a wall-mounted type or a ceiling-suspended type. The indoor unit 4 communicates with a server device 6.

[0020] The indoor unit 4 is equipped with a second air purification device 7. The second air purifier 7 applies a high voltage to water in the air to generate nano-sized particle ions, and releases the generated particle ions into the target space SP through the outlet of the indoor unit 4. In this way, the second air purifier 7 purifies the air in the target space SP by the oxidizing power of OH radicals contained in the particle ions. The particle ions released by the second air purifier 7 have sterilizing and deodorizing effects.

[0021] The indoor unit 4 transmits first status data D3 to the server device 6 at a predetermined cycle. The first status data D3 is data indicating the state of the indoor unit 4, and records whether the second air purifier 7 is operating, the volume of air supplied by the indoor unit 4, and the wind direction of the indoor unit 4. An indoor unit ID for identifying the indoor unit 4 is added to the first status data D3. The indoor unit 4 may communicate with the server device 6 connected to the network NW via a local network constructed in the building H, or may communicate with the server device 6 without going through the local network.

[0022] The display system 1000 includes a first air purification device 5. The display system 1000 of the present embodiment includes one first air purification device 5. The first air purifier 5 passes the intake air through a filter permeated with an aqueous hypochlorous acid solution, and releases air containing hypochlorous acid. The air released by the first air purifier 5 has a sterilizing effect, a deodorizing effect, and the like. The first air purifier 5 of this embodiment is a ceiling-embedded type device, and releases hypochlorous acid from the outlet IH through a duct. The type of the first air purifier 5 is not limited to the ceiling-embedded type, and may be another type such as a freestanding type that is placed in the target space SP. Hereinafter, when there is no distinction between the hypochlorous acid released by the first air purifying device 5 and the particulate ions released by the second air purifying device 7, they will be referred to as the "air purifying material."

[0023] The first air purifying device 5 transmits second status data D4 to the server device 6 at a predetermined cycle. The second status data D4 is data indicating the state of the first air purifying device 5, and records whether or not hypochlorous acid is being released and the volume of air supplied by the first air purifying device 5. A device ID for identifying the first air purifying device 5 is added to the second status data D4. The first air purifying device 5 may communicate with the server device 6 connected to the network NW via a local network constructed in the building H, or may communicate with the server device 6 without going through the local network.

[0024] The display system 1000 includes a terminal device 1. In this embodiment, a device equipped with a touch panel 12 is exemplified as the terminal device 1. Examples of the terminal device 1 in this embodiment include a smartphone and a tablet computer. An application program for displaying the air condition of the target space SP is installed in the terminal device 1. In the following description, this application program is referred to as a "display application" and is denoted by the symbol "111". The terminal device 1 communicates with the server device 6 by the function of the display application 111. The display application 111 is an example of a "program."

[0025] The display system 1000 includes a server device 6 . The server device 6 is a device that processes information from the air quality sensor 2, the wind speed sensor 3, the indoor unit 4, the first air purifying device 5, and the terminal device 1 as clients. The server device 6 is connected to the network NW and communicates with these clients. Note that in each drawing, the server device 6 is represented by a single block, but this does not necessarily mean that the server device 6 is composed of a single device.

[0026] Next, the configurations of the terminal device 1 and the server device 6 will be described. FIG. 3 is a diagram showing the configuration of the terminal device 1 and the server device 6. As shown in FIG.

[0027] [1-2. Server device configuration] Next, the configuration of the server device 6 will be described. The server device 6 includes a server control device 60 and a server communication unit 61. The server control device 60 is a control device that controls each part of the server device 6. The server control device 60 includes a server processor 600, which is a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processor Unit), a server memory 610, and an interface circuit for connecting other devices and sensors, and controls each part of the server device 6.

[0028] The server memory 610 is a memory that stores programs and data. The server memory 610 stores a control program 611, a first management DB (database) 612, a second management DB 613, and data to be processed by the server processor 600. The server memory 610 has a non-volatile storage area. The server memory 610 may also have a volatile storage area and constitute a work area of ​​the server processor 600. The server memory 610 is constituted by, for example, a ROM or a RAM.

[0029] FIG. 4 is a diagram showing an example of the first management DB 612 and the second management DB 613. As shown in FIG. The first management DB 612 has a record R1 for each target space SP. Record R1 has a first field, a second field, a third field, and a fourth field. In record R1, a spatial ID is associated with these fields.

[0030] In the first field, a combination of a first sensor ID and first detection data D1 is recorded for each air quality sensor 2 installed in the target space SP. In the second field, a combination of the second sensor ID and the second detection data D2 is recorded for each wind speed sensor 3 installed in the target space SP. In the third field, a combination of the indoor unit ID and the first status data D3 is recorded for each indoor unit 4 that conditions the target space SP. In the fourth field, a combination of the device ID and the second status data D4 is recorded for each first air purifying device 5 that supplies hypochlorous acid to the target space SP.

[0031] The second management DB 613 has a record R2 for each target space SP. Record R2 has a space ID, space image data, area image data, management data, and position data.

[0032] The spatial image data is image data representing the spatial image G1, which will be described later. The area image data is image data representing the area image G2, which will be described later. The first management data is data for managing which indoor unit 4 is installed in which area ER, which air quality sensor 2 is installed in which area ER, and which wind speed sensor 3 is installed in which area ER. More specifically, in the management data, the IDs of the devices installed in the area ER (first sensor ID, second sensor ID, indoor unit ID) are recorded for each area ER. The second management data records, for each air quality sensor 2, a combination of the position of the spatial image G1 corresponding to the position of the air quality sensor 2 in the target space SP, a first sensor ID, and a second sensor ID. Furthermore, the second management data records, for each indoor unit 4, a combination of the position of the spatial image G1 corresponding to the position of the indoor unit 4 in the target space SP, and the indoor unit ID. Furthermore, the second management data records, for each outlet IH, the position of the spatial image G1 corresponding to the position of the outlet IH in the target space SP.

[0033] The server communication unit 61 includes communication hardware such as a communication circuit, and communicates with the air quality sensor 2, the wind speed sensor 3, the indoor unit 4, the first air purifying device 5, and the terminal device 1 under the control of the server control device 60. The communication standard of the server communication unit 61 may be a wireless communication standard or a wired communication standard.

[0034] The server processor 600 reads and executes a control program 611 stored in a server memory 610 , thereby functioning as a server communication control unit 601 and an update unit 602 .

[0035] The server communication control unit 601 communicates with the air quality sensor 2, the indoor unit 4, the first air purification device 5, and the terminal device 1 via the server communication unit 61.

[0036] The update unit 602 updates the contents of record R1. When the server communication control unit 601 receives first detection data D1, the update unit 602 updates the first detection data D1 corresponding to the first sensor ID added to the received first detection data D1 to the received first detection data D1. When the server communication control unit 601 receives second detection data D2, the update unit 602 updates the second detection data D2 corresponding to the second sensor ID added to the received second detection data D2 to the received second detection data D2. When the server communication control unit 601 receives the first status data D3, the update unit 602 updates the first status data D3 corresponding to the indoor unit ID added to the received first status data D3 to the received first status data D3. When the server communication control unit 601 receives second status data D4, the update unit 602 updates the second status data D4 corresponding to the device ID attached to the received second status data D4 to the received second status data D4.

[0037] [1-3. Terminal device configuration] Next, the configuration of the terminal device 1 will be described. The terminal device 1 includes a terminal control device 10, a terminal communication unit 11, and a touch panel 12. The terminal control device 10 is a control device that controls each part of the terminal device 1. The terminal control device 10 includes a terminal processor 100, which is a processor such as a CPU or an MPU, a terminal memory 110, and an interface circuit for connecting other devices and sensors, and controls each part of the terminal device 1. The terminal processor 100 corresponds to an example of a “processor.” The touch panel 12 corresponds to an example of a “display unit.”

[0038] The terminal memory 110 is a memory that stores programs and data. The terminal memory 110 stores a display application 111 and data to be processed by the terminal processor 100. The terminal memory 110 has a non-volatile storage area. The terminal memory 110 may also have a volatile storage area and constitute a work area for the terminal processor 100. The terminal memory 110 is constituted by, for example, a ROM or a RAM.

[0039] The terminal communication unit 11 includes communication hardware such as a communication circuit, and communicates with the server device 6 connected to the network NW under the control of the terminal control device 10. The communication standard of the terminal communication unit 11 may be a wireless communication standard or a wired communication standard.

[0040] The touch panel 12 includes a display panel and a touch sensor that is provided over the display panel or is integral with the display panel. The display panel displays various information under the control of the terminal control device 10. The touch sensor detects a touch operation and outputs a detection signal to the terminal control device 10. The terminal control device 10 executes a process corresponding to the touch operation based on an input from the touch sensor.

[0041] The terminal processor 100 reads out and executes a display application 111 stored in the terminal memory 110, thereby functioning as a terminal communication control unit 101, an evaluation unit 102, a display control unit 103, and a reception unit 104.

[0042] The terminal communication control unit 101 communicates with the server device 6 via the terminal communication unit 11 .

[0043] The evaluation unit 102 evaluates the state of the air quality detected by the air quality sensor 2 based on the detection value of the air quality sensor 2. The evaluation unit 102 evaluates the degree of goodness or badness of the air quality state for each type of air quality. The evaluation unit 102 evaluates the degree of goodness or badness of the air quality state in multiple stages. For example, the evaluation unit 102 evaluates in five stages, namely, "Very Poor", "Poor", "Fair", "Best", and "Very Best". In this example, the evaluation results of the evaluation unit 102 indicate high evaluation, that is, good air quality state, in the order of "Very Poor", "Poor", "Fair", "Best", and "Very Best". In this example, the evaluation stages of the evaluation unit 102 are not limited to five stages. The evaluation stages of the evaluation unit 102 may be four stages or less, or six stages or more.

[0044] The evaluation index of the evaluation unit 102 differs for each type of air quality. That is, the evaluation unit 102 evaluates the detection value of the air quality sensor 2 for each type of air quality using the evaluation index defined for each type of air quality. Although the unit of the detection value differs depending on the type of air quality, the evaluation unit 102 can perform an appropriate evaluation regardless of the type of air quality by using the evaluation index defined for each type of air quality. The evaluation unit 102 outputs the evaluation result to the display control unit 103.

[0045] The display control unit 103 displays a user interface that displays the state of air quality in the target space SP on the touch panel 12. In the following description, this user interface will be referred to as an "application UI" and will be given the reference number "120."

[0046] The reception unit 104 receives various operations from the user P via the application UI 120 .

[0047] [1-4. App UI configuration] Next, the application UI 120 will be described. FIG. 5 is a diagram showing an example of the application UI 120.

[0048] The application UI 120 has a first area A1, a second area A2, a third area A3, and a fourth area A4. In Fig. 5, the first area A1 and the second area A2 are aligned in the left-right direction, and the third area A3 and the fourth area A4 are aligned in the left-right direction below the first area A1 and the second area A2. Note that the arrangement of the first area A1 to the fourth area A4 is not limited to the arrangement shown in Fig. 5. The first area A1 is an area that displays the state of the air quality of the target space SP. The first area A1 will be described in detail with reference to FIG.

[0049] FIG. 6 is a diagram showing an example of the first area A1. The first area A1 displays a spatial image G1. The spatial image G1 is an image looking down on the target space SP from a specific viewpoint, and shows the target space SP three-dimensionally. The target space SP shown in the spatial image G1 imitates the actual target space SP. Therefore, the layout of the target space SP shown in the spatial image G1 conforms to the actual layout. Furthermore, in the target space SP shown in the spatial image G1, at least the indoor unit 4 and the outlet IH are shown in the same installation positions as the actual installation positions.

[0050] In the first area A1, the position of the viewpoint looking down on the target space SP can be changed. More specifically, in the first area A1, the position of the line of sight looking down on the target space SP can be changed by rotating it within a range of 360° around the axis of the center of the horizontal plane of the target space SP. The reception unit 104 receives a swipe operation or a flick operation in the first area A1. The swipe operation is an operation in which the contact position of the user P's fingers or the like in contact with the touch panel 12 is moved. The flick operation is an operation in which the user P's fingers or the like in contact with the touch panel 12 are removed from the touch panel 12 in a flicking manner. When the reception unit 104 receives a swipe operation or a flick operation in the left-right direction in FIG. 6, a space image G1 in which the position of the viewpoint overlooking the target space SP is changed according to the amount of operation is displayed in the first area A1.

[0051] The first area A1 displays a first object OJ1 superimposed on the spatial image G1. The first object OJ1 is an object and an image showing a plurality of types of air quality conditions. One first object OJ1 is displayed in the spatial image G1 at a position corresponding to the installation position of the air quality sensor 2. In this embodiment, six air quality sensors 2 are installed in the target space SP. Therefore, the spatial image G1 displays the first object OJ1 at each position corresponding to each of the six air quality sensors 2. That is, the spatial image G1 of this embodiment displays six first objects OJ1 at different positions. Note that, in each drawing, the first object OJ1 is not colored for ease of understanding, but the actual first object OJ1 is colored.

[0052] FIG. 7 is a diagram showing an example of the first object OJ1. The first object OJ1 has one or more second objects OJ2. That is, when the first object OJ1 has multiple second objects OJ2, the first object OJ1 becomes an object that is a combination of the multiple second objects OJ2. One second object OJ2 is an object related to one type of air quality and indicates the state of the air quality. The second object OJ2 is an image. When the first object OJ1 has multiple second objects OJ2, the first area A1 displays the multiple second objects OJ2 with at least a portion of the second objects OJ2 overlapping each other.

[0053] The color of the second object OJ2 corresponds to the evaluation result of the evaluation unit 102. As described above, the evaluation unit 102 evaluates the degree of quality of the air quality state detected by the air quality sensor 2 for each type of air quality. The second object OJ2 is displayed in a color according to a hue ranging from red to blue. The lower the evaluation result of the evaluation unit 102, the closer the color of the second object OJ2 is to red. On the other hand, the higher the evaluation result of the evaluation unit 102, the closer the color of the second object OJ2 is to blue.

[0054] As described above, when a first object OJ1 has multiple second objects OJ2, the first area A1 displays the first object OJ1 in a state in which the second objects OJ2 at least partially overlap each other. In the first object OJ1, the color of an overlapping area TA1 where the second object OJ2 overlaps is different from the color of a non-overlapping area TA2 where the second object OJ2 does not overlap. The color of the overlapping area TA1 is set to a mixture of the colors of the overlapping second objects OJ2. The color of the non-overlapping area TA2 is set to the color of the corresponding second object OJ2.

[0055] 7 illustrates an example in which the first object OJ1 has a second object OJ2-1 and a second object OJ2-2. Therefore, in FIG. 7, the color of the overlapping area TA1 is set to a mixed color of the second objects OJ2-1 and OJ2-2. Also, in FIG. 7, the color of the non-overlapping areas TA2-1, TA2-3, and TA2-5 is set to the color of the second object OJ2-1. Also, in FIG. 7, the color of the non-overlapping areas TA2-2, TA2-4, and TA2-5 is set to the color of the second object OJ2-2.

[0056] The first object OJ1 has second objects OJ2 in a number corresponding to the number of items selected in the selection area SA of the first area A1. The selection area SA is an area for selecting an object to be displayed in the first area A1, and has the following seven items: Item 1: Item that displays objects related to airflow Item 2: Items showing objects related to air purifying substances Item 3: Item that displays objects related to humidity and temperature of the target space SP Item 4: Item that displays an object related to the CO2 concentration in the target space SP Item 5: Item that displays objects related to PM2.5 concentration in the target space SP Item 6: Item that displays an object related to the microbial concentration in the target space SP Item 7: Item that displays odor-related objects in the target space SP

[0057] When none of the items from the third item to the seventh item is selected in the selection area SA, the first object OJ1 is not displayed in the spatial image G1. On the other hand, when one or more items from the third item to the seventh item are selected in the selection area SA, the first object OJ1 having the second object OJ2 corresponding to the selected item is displayed in the spatial image G1. For example, when five items from the third item to the seventh item are selected, the first object OJ1 having five second objects OJ2 corresponding to the five items is displayed in the spatial image G1.

[0058] The first object OJ1 has evaluation information HJ displayed for each second object OJ2 that the first object OJ1 has. The evaluation information HJ is information in which the name of an item and the evaluation result of the evaluation unit 102 are associated with each other.

[0059] In the evaluation information HJ of the second object OJ2 corresponding to the third item, for example, the evaluation result of the temperature and humidity detected by the air quality sensor 2 is associated with the item name "Unconfort Level." In the evaluation information HJ of the second object OJ2 corresponding to the fourth item, for example, an evaluation result regarding the CO2 concentration detected by the air quality sensor 2 is associated with the item name "CO2 Level." In the evaluation information HJ of the second object OJ2 corresponding to the fifth item, for example, the evaluation result of the PM2.5 concentration detected by the air quality sensor 2 is associated in alphabetical order with the item name "Unclean Level." In the evaluation information HJ of the second object OJ2 corresponding to the sixth item, for example, the evaluation result of the microbial concentration detected by the air quality sensor 2 is associated with the item name "Sanitixe Level." In the evaluation information HJ of the second object OJ2 corresponding to the seventh item, for example, an evaluation result regarding the odor detected by the air quality sensor 2 is associated with the item name "Scent Level."

[0060] When the detection value of the air quality sensor 2 for the air quality indicated by the second object OJ2 owned by the first object OJ1 is equal to or greater than a threshold, an alert AR is displayed in association with the first object OJ1. This threshold varies for each type of air quality, and is determined in advance through prior testing and simulation based on the necessity of displaying the alert AR.

[0061] FIG. 8 is a diagram showing an example of the alert AR. In FIG. 8, an exclamation mark is used as the alert AR, but the alert AR may be another symbol, a character, a character string, an image, or the like. FIG. 8 shows that the CO2 concentration is above the threshold value.

[0062] The second object OJ2 will now be described in detail. The second object OJ2 in each of the third and fourth items has a third object OJ3 therein. FIG. 9 is a diagram for explaining the third object OJ3.

[0063] The third object OJ3 is an object and an image representing an air pollutant that pollutes the air of the target space SP. The third object OJ3 included in the second object OJ2 of the third item is an object representing PM2.5. The third object OJ3 included in the second object OJ2 of the fourth item is an object representing a microorganism. At least one of the shape and color of the third object OJ3 varies depending on the type of item. FIG. 9 illustrates a case where the shape of the third object OJ3 varies depending on the type of item. Note that the shape and color of the third object OJ3 may be the same regardless of the type of item.

[0064] In FIG. 9, the second object OJ2 corresponding to the third item is a second object OJ2-3, and the shape of the third object OJ3 included in the second object OJ2-3 is a circle. In FIG. 9, the second object OJ2 corresponding to the fourth item is the second object OJ2-4, and the shape of the third object OJ3 included in the second object OJ2-4 is triangular.

[0065] The number of third objects OJ3 included in the second object OJ2 corresponds to the state of air quality, i.e., the detection value of the air quality sensor 2. That is, the number of third objects OJ3 included in the second object OJ2 of the third item increases as the PM2.5 concentration detected by the air quality sensor 2 increases. Similarly, the number of third objects OJ3 included in the second object OJ2 of the fourth item increases as the microorganism concentration detected by the air quality sensor 2 increases.

[0066] When a first object OJ1 has two second objects OJ2, a third item and a fourth item, the total number of third objects OJ3 owned by the first object OJ1 is the sum of the number of third objects OJ3 owned by the second object OJ2 in the third item and the number of third objects OJ3 owned by the second object OJ2 in the fourth item.

[0067] The second object OJ2 is displayed such that the outer edge OE of the closed curve changes shape over time. More specifically, the second object OJ2 is displayed such that the outer edge OE wobbles. The outer edge OE being displayed with a wavy appearance means that the outer edge OE is displayed in a wavy manner. In other words, the outer edge OE being displayed with a wavy appearance means that the positions of the concave and convex portions of the outer edge OE change over time. It should be noted that the shape of the second object OJ2 is the same regardless of the type of air quality when the outer edge OE is not fluctuated.

[0068] FIG. 10 is a diagram showing an example of a change in the display mode of the second object OJ2. When the second object OJ2 is displayed, the outer edge OE of the second object OJ2 returns to its original shape at a predetermined cycle. Fig. 9 shows an example in which the outer edge OE of the second object OJ2 returns to the shape J1 via five shapes, J2, J3, J4, J5, and J6. Note that the number of shapes through which the outer edge OE of the second object OJ2 passes is not limited to six, and may be five or less, or may be more.

[0069] The outer edge OE of the second object OJ2 has a different shape depending on the type of item selectable in the selection area SA. This can reduce the frequency of the second objects OJ2 completely overlapping each other when the first object OJ1 has multiple second objects OJ2. Note that the outer edge OE of the second object OJ2 may have the same shape regardless of the type of item selectable in the selection area SA, but in this case, it is preferable to make the timing of returning to the original shape different for each second object OJ2. This can reduce the frequency of the second objects OJ2 completely overlapping each other when the first object OJ1 has multiple second objects OJ2.

[0070] The outer edge OE of the second object OJ2 varies in degree of fluctuation depending on the wind speed detected by the wind speed sensor 3. The different degrees of fluctuation refer to at least one of the following: the predetermined period in which the shape of the outer edge OE returns to its original shape varies; and the size of the uneven portion of the outer edge OE varies. When the predetermined period is varied, the outer edge OE of the second object OJ2 returns to its original shape in a shorter period as the wind speed detected by the wind speed sensor 3 increases. When the size of the uneven portion is varied, the larger the wind speed detected by the wind speed sensor 3, the larger the size of the uneven portion of the outer edge OE of the second object OJ2.

[0071] Returning to the explanation of FIG. 6, a fourth object OJ4 and a fifth object OJ5 are displayed superimposed on the spatial image G1. The fourth object OJ4 is an object representing an air current, and is an image representing the air current with a line. The fifth object OJ5 is an object representing an air purifying substance, and is an image representing the air purifying substance with a dot. In FIG. 6, each of the lines extending from the indoor unit 4 and the outlet IH shown in the spatial image G1 is the fourth object OJ4. Also, in FIG. 6, each of the points existing in the target space SP shown in the spatial image G1 is the fifth object OJ5.

[0072] The fourth object OJ4 is displayed in association with the indoor unit 4 indicated by the spatial image G1. The fourth object OJ4 is displayed to avoid overlapping with the first object OJ1, for example, so that the overlapping area is equal to or smaller than a predetermined value. The length of the fourth object OJ4 extending from the indoor unit 4 is set to a length according to the volume of air supplied from the indoor unit 4 to the target space SP. That is, the length of the fourth object OJ4 extending from the indoor unit 4 is set to be longer as the volume of air supplied by the indoor unit 4 is larger. Also, the direction in which the fourth object OJ4 extends from the indoor unit 4 corresponds to the wind direction of the indoor unit 4. The length of the fourth object OJ4 extending from the release port IH is set to a length according to the volume of air at which the release port IH releases hypochlorous acid. That is, the greater the volume of air at which the release port IH releases hypochlorous acid, the longer the length of the fourth object OJ4 extending from the release port IH is set.

[0073] The fourth object OJ4 is displayed in a manner that extends from the indoor unit 4 or the outlet IH shown in the spatial image G1 over time, and disappears when it extends to a set length. The number of fourth objects OJ4 extending from the indoor unit 4 per unit time may correspond to the volume of air supplied to the target space SP by the indoor unit 4. Also, the number of fourth objects OJ4 extending from the outlet IH shown in the spatial image G1 per unit time may correspond to the volume of air supplied from the outlet IH to the target space SP.

[0074] The fifth object OJ5 is displayed in a manner in which it is emitted from the indoor unit 4 or the outlet IH shown in the spatial image G1. After being emitted from the indoor unit 4 or the outlet IH shown in the spatial image G1, the fifth object OJ5 is displayed in a manner in which it diffuses within the target space SP shown in the spatial image G1 over time. The diffusion manner of the fifth object OJ5 is determined by prior tests and simulations. The number of fourth objects OJ4 discharged per unit time from the indoor unit 4 increases as the volume of air supplied from the indoor unit 4 to the target space SP increases. Also, the number of fourth objects OJ4 discharged per unit time from the outlet IH increases as the volume of air supplied from the outlet IH to the target space SP increases.

[0075] The color of the fifth object OJ5 emitted from the indoor unit 4 is set to a color different from the color of the fifth object OJ5 emitted from the outlet IH. For example, the color of the fifth object OJ5 corresponding to the particulate ions emitted from the indoor unit 4 is set to light blue, and the color of the fifth object OJ5 corresponding to the hypochlorous acid emitted from the outlet IH is set to yellow. This allows the user P to understand the diffusion state of the air purifying substance for each type of air purifying substance.

[0076] As described above, the selection area SA is an area for selecting an object to be displayed in the first area A1, and has seven items, from the first item to the seventh item. When the first item is not selected in the selection area SA, the fourth object OJ4 is not displayed in the spatial image G1. On the other hand, when the first item is selected in the selection area SA, the fourth object OJ4 is displayed in the spatial image G1. Furthermore, when the second item is not selected in the selection area SA, the fifth object OJ5 is not displayed in the spatial image G1. On the other hand, when the second item is selected in the selection area SA, the fifth object OJ5 is displayed in the spatial image G1.

[0077] Returning to the description of FIG. 5, the second area A2 is an area for displaying the area image G2. The area image G2 is a schematic image of the target space SP viewed from above, and is an image showing each of the areas ER provided in the target space SP. The area image G2 has an area-specific image G21 for each area ER. The area image G2 shown in FIG. 5 has six area images G2, namely, area-specific images G21-1, G21-2, G21-3, G21-4, G21-5, and G21-6. The area-specific image G21-1 shows the area ER1, the area-specific image G21-2 shows the area ER2, the area-specific image G21-3 shows the area ER3, the area-specific image G21-4 shows the area ER4, the area-specific image G21-5 shows the area ER5, and the area-specific image G21-6 shows the area ER6.

[0078] The second area A2 displays each of the area-specific images G21 in a selectable manner. That is, the area image G2 displayed in the second area A2 displays the area ER in a selectable manner. When one area ER is selected in the second area A2, the third area A3 displays the detection values ​​of the air quality sensor 2 installed in the selected area ER for each type of air quality.

[0079] Fig. 11 is a diagram showing an example of the application UI 120. Fig. 11 shows the application UI 120 when the area-specific image G21-3 is selected. As described above, the third area A3 displays the detection values ​​of the air quality sensor 2 installed in the area ER selected in the second area A2 for each type of air quality. Fig. 11 shows a case where the area-specific image G21-3 is selected. Therefore, the third area A3 in Fig. 10 displays the detection values ​​of the air quality sensor 2 installed in the area ER3 for each type of air quality.

[0080] Returning to the explanation of Fig. 5, the fourth area A4 is an indicator IC that indicates the evaluation of the color of the second object OJ2, which allows the user P to more clearly understand the state of the air quality indicated by the second object OJ2.

[0081] [1-2. Operation] Next, the operation of each unit of the display system 1000 will be described. First, the operation of the display system 1000 related to the start of displaying the application UI 120 will be described. FIG. 12 is a flowchart showing the operation of the display system 1000. In FIG. 12, a flowchart FA shows the operation of the terminal device 1, and a flowchart FB shows the operation of the server device 6.

[0082] As shown in a flowchart FA, the terminal communication control unit 101 transmits start request information to the server device 6 (step SA1). The process of step SA1 is performed when an instruction to start displaying the application UI 120 is received from the user P, for example, when the display application 111 is launched.

[0083] The start request information is information that requests various data related to the display of the application UI 120. The request information includes the space ID of the target space S. The space ID is input to the terminal device 1 at a predetermined timing.

[0084] As shown in the flow chart FB, the server communication control unit 601 receives start request information (step SB1).

[0085] Next, the server communication control unit 601 collects various data to be transmitted to the terminal device 1 (step SB2).

[0086] Step SB2 will now be described in detail. In step SB2, the server communication control unit 601 identifies, from the first management DB 612, a record R1 of the space ID included in the start request information, and collects the identified record R1 as various data to be transmitted to the terminal device 1. Furthermore, in step SAB2, the server communication control unit 601 identifies, from the second management DB 613, record R2 of the space ID included in the start request information, and collects the identified record R2 as various data to be transmitted to the terminal device 1.

[0087] Next, the server communication control unit 601 transmits the various data collected in step SB2 to the terminal device 1 (step SB3).

[0088] As shown in the flow chart FA, terminal communication control unit 101 receives the various data collected in step SB2 from server device 6 (step SA2).

[0089] Next, the evaluation unit 102 evaluates the state of air quality detected by each air quality sensor 2 (step SA3). Step SA3 is an example of an "evaluation step."

[0090] In step SA3, the evaluation unit 102 performs the following process for each air quality sensor 2, i.e., for each first detection data D1 of the record R1 received in step SA2. That is, the evaluation unit 102 evaluates the detection value of the air quality indicated by the first detection data D1 for each type of air quality.

[0091] Next, the display control unit 103 displays the application UI 120 on the touch panel 12 (step SA4). Step SA4 is an example of a "display step."

[0092] The process of step SA4 will now be described in detail. In step SA4, the display control unit 103 acquires the evaluation result of step SA3 from the evaluation unit 102. More specifically, the display control unit 103 acquires the evaluation result for each type of air quality for each piece of first detection data D1 of record R1 received in step SA2.

[0093] In step SA4, the display control unit 103 displays, in the first area A1, a spatial image G1 indicated by the spatial image data of the record R1 received in step SA2.

[0094] Furthermore, in step SA4, the display control unit 103 displays the first object OJ1 in the space image G1 displayed in the first area A1. Here, the display of the first object OJ1 will be described.

[0095] When displaying the first object OJ1, the display control unit 103 generates a second object OJ2 and also determines the degree of fluctuation of the outer edge OE.

[0096] The display control unit 103 generates a second object OJ2 for each type of air quality for each air quality sensor 2, that is, for each piece of first detection data D1 received in step SA2, based on the acquired evaluation results. In generating the second object OJ2, the display control unit 103 generates the second object OJ2 with a color according to the evaluation result of the evaluation unit 102. In generating the second object OJ2 of the third item, the display control unit 103 generates the second object OJ2 having the number of third objects OJ3 according to the detection value of the PM2.5 concentration indicated by the first detection data D1. In generating the second object OJ2 of the fourth item, the display control unit 103 generates the second object OJ2 having the number of third objects OJ3 according to the detection value of the microbial concentration indicated by the first detection data D1.

[0097] The display control unit 103 determines the degree of fluctuation of the outer edge OE for each air quality sensor 2, that is, for each piece of first detection data D1 received in step SA2. The display control unit 103 refers to the second management data received in step SA2 and identifies, for each of the first detection data D1, the second detection data D2 corresponding to the first detection data D1. Then, for each of the first detection data D1, the display control unit 103 determines the degree of fluctuation of the outer edge OE of the second object OJ2 to a degree according to the wind speed indicated by the identified second detection data D2.

[0098] The display control unit 103 determines the generation of the second object OJ2 and the degree of fluctuation of the outer edge OE for each air quality sensor 2, i.e., for each first detection data D1 received in step SA2, and then displays the first object OJ1 by superimposing it on the spatial image G1. The display control unit 103 refers to the second management data and the record R1 received in step SA2 and recognizes which positions in the spatial image G1 correspond to each of the first detection data D1 received in step SA2. Then, the display control unit 103 displays the first object OJ1 for each air quality sensor 2, i.e., for each first detection data D1 received in step SA2, so as to achieve the recognized correspondence. In displaying the first object OJ1, the display control unit 103 fluctuates the generated second object OJ2 with the determined degree of fluctuation of the outer edge OE, and changes the colors of the overlapping area TA1 and the non-overlapping area TA2.

[0099] Returning to the explanation of the display in the first area A1, in step SA4, the display control section 103 displays the evaluation information HJ. Here, the display of the evaluation information HJ will be described. The display control unit 103 generates evaluation information HJ for each type of air quality for each air quality sensor 2, i.e., for each piece of first detection data D1 received in step SA2, based on the evaluation results obtained from the evaluation unit 102. Next, the display control unit 103 recognizes which position in the spatial image G1 each piece of first detection data D1 received in step SA2 corresponds to, in the same manner as in displaying the first object OJ1. Then, the display control unit 103 displays the generated evaluation information HJ in the spatial image G1 for each piece of first detection data D1 received in step SA2 so as to match the recognized correspondence.

[0100] Returning to the explanation of the display of the first area A1, in step SA4, the display control unit 103 displays the fourth object OJ4 and the fifth object OJ5 so as to be superimposed on the spatial image G1.

[0101] The display control unit 103 refers to the second management data and record R1 received in step SA2 and recognizes which position in the spatial image G1 each piece of first status data D3 corresponds to. Then, the display control unit 103 displays the fourth object OJ4 according to the air volume and air direction of the indoor unit 4 indicated by the first status data D3 for each piece of first status data D3 so as to achieve the recognized correspondence. Here, the display position of the first object OJ1 is determined so as not to overlap with the fourth object OJ4. The display control unit 103 refers to the second management data and the record R1 received in step SA2, and displays the fifth object OJ5 from the outlet IH indicated in the spatial image G1 according to the air volume indicated by the second status data D4. Then, the display control unit 103 diffuses the fifth object OJ5 in the spatial image G1 with the passage of time.

[0102] In step SA4, the display control unit 103 displays, in the second area A2, the area image G2 indicated by the area image data received in step SA2.

[0103] In addition, in step SA4, the display control unit 103 displays the indicator IC in the fourth area A4. Note that image data of the indicator IC may be recorded in the display memory 110 when the display application 111 is installed, or may be received from the server device 6 together with various data in step SA2.

[0104] By the process of step SA4, the display control unit 103 can display the application UI 120 as shown in FIG.

[0105] Next, the operation of the display system 1000 related to updating the display content of the application UI 120 will be described. FIG. 13 is a flowchart showing the operation of the display system 1000. In FIG. 13, a flowchart FC shows the operation of the terminal device 1, and a flowchart FD shows the operation of the server device 6.

[0106] As shown in the flowchart FC, the terminal communication control unit 101 transmits update request information to the server device 6 (step SC1). The process of step SC1 is performed when a predetermined period of time has elapsed since the display of the application UI 120 started, or when a predetermined period of time has elapsed since the display contents of the application UI 120 were last updated.

[0107] The update request information is information that requests an update of the display content of the application UI 120. The update request information includes the space ID of the target space SP.

[0108] As shown in the flow chart FD, the server communication control unit 601 receives update request information (step SD1).

[0109] Next, the server communication control unit 601 collects various data to be transmitted to the terminal device 1 (step SD2).

[0110] Step SD2 will now be described in detail. In step SD2, the server communication control unit 601 identifies, from the first management DB 612, a record R1 of the space ID included in the update request information, and collects the identified record R1 as various data to be transmitted to the terminal device 1. Furthermore, in step SD2, the server communication control unit 601 identifies, from the second management DB 613, record R2 of the space ID included in the start request information, and collects the identified record R2 as various data to be transmitted to the terminal device 1.

[0111] Next, the server communication control unit 601 transmits the various data collected in step SD2 to the terminal device 1 (step SD3).

[0112] As shown in the flow chart FC, the terminal communication control unit 101 receives the various data collected in step SD2 from the server device 6 (step SC2).

[0113] Next, the evaluation unit 102 evaluates the state of the air quality detected by each air quality sensor 2 (step SC3). In step SC3, the evaluation unit 102 performs the same evaluation as in step SA3. Step SC3 is an example of an "evaluation step."

[0114] Next, the display control unit 103 displays the application UI 120 on the touch panel 12 (step SC4). In step SC4, the display control unit 103 generates each object and evaluation information HJ, similar to step SA4, and displays them in the first area A1. Step SC4 is an example of a "display step."

[0115] Next, the operation of the terminal device 1 while the application UI 120 is being displayed will be described. First, the operation of the terminal device 1 related to the selection of an item in the selection area SA will be described. Fig. 14 is a flowchart FE showing the operation of the terminal device 1. The process of Fig. 14 is repeatedly performed while the application UI 120 is displayed.

[0116] The display control unit 103 determines whether or not an item is selected in the selection area SA (step SE1). That is, in step SE1, the display control unit 103 determines whether or not the receiving unit 104 has received the selection of an item.

[0117] When it is determined that an item is selected in the selection area SA (step SE1: YES), the display control unit 103 displays an object corresponding to the item selected in the selection area SA (step SE2).

[0118] In step SE2, when at least one of the third to seventh items is selected in the selection area SA, the display control section 103 displays the evaluation information HJ corresponding to the selected item.

[0119] Returning to the explanation of step SE1, if the display control unit 103 determines that no item is selected in the selection area SA (step SE1: NO), it determines whether the receiving unit 104 has received the selection of an item in the selection area SA (step SE3).

[0120] When display control unit 103 determines that acceptance unit 104 has not accepted the selection of an item (step SE3: NO), display control unit 103 returns the process to step SA1 and performs the processes from step SA1 onwards again.

[0121] On the other hand, if it is determined that the selection of an item has been accepted by the accepting unit 104 (step SE3: YES), the display control unit 103 displays an object corresponding to the selected item (step SE4).

[0122] In step SE4, when at least one of the third to seventh items is selected in the selection area SA, the display control section 103 displays the evaluation information HJ corresponding to the selected item.

[0123] Next, the operation of the terminal device 1 related to the selection of the area ER will be described. 15 is a flowchart FF showing the operation of the terminal device 1. The process of FIG. 15 is repeatedly performed independently of FIG.

[0124] The display control unit 103 determines whether or not the area-specific image G21 is selected (step SF1). That is, in step SF1, the display control unit 103 determines whether or not the reception unit 104 has received a selection of the area ER in the area image G2.

[0125] When the display control unit 103 determines that the area-specific image G21 has been selected (step SF1: YES), it displays the detection value of the air quality sensor 2 installed in the area ER corresponding to the selected area-specific image G21 in the third area A3 (step SF2).

[0126] Returning to the explanation of step SF1, if the display control unit 103 determines that the area-specific image G21 has not been selected (step SF1: NO), it determines whether or not the area-specific image G21 has been selected (step SF3). That is, in step SF1, the display control unit 103 determines whether or not the reception unit 104 has received the selection of the area ER in the area image G2.

[0127] When it is determined that the area-specific image G21 has not been selected (step SF3: NO), the display control unit 103 returns the process to step SF1 and performs the processes from step SF1 onwards again.

[0128] On the other hand, if the display control unit 103 determines that the area-specific image G21 has been selected (step SF3: YES), it displays the detection value of the air quality sensor 2 corresponding to the selected area-specific image G21 (step SF4). In step SF4, the display control unit 103 refers to the received first management data and recognizes the first sensor ID of the air quality sensor 2 installed in the selected area ER. Then, the display control unit 103 identifies the first detection data D1 corresponding to the recognized first sensor ID from the received record R1, and displays the detection value of the air quality sensor 2 indicated by the identified first detection data D1 in the third area A3.

[0129] [1-3. Effects, etc.] As described above, the display method by the display system 1000 includes an evaluation step of evaluating the state of air quality for each type of air quality based on the detection value of the air quality sensor 2 that detects the state of air quality in the target space SP. The display method also includes a display step in which the terminal device 1 displays a first object OJ1 indicating the state of air quality in a spatial image G1 showing the target space SP based on the evaluation result of the evaluation step. The first object OJ1 is a combination of a plurality of second objects OJ2 indicating the state of air quality for each type of air quality. The display step displays the second object OJ2 in a color corresponding to the evaluation result of the evaluation step for each second object OJ2, and displays the second object OJ2 in a different display mode for each second object OJ2.

[0130] According to this, by displaying the second objects OJ2 in colors corresponding to the evaluation results, the impression of the overall air quality state considering the multiple types of air quality states can be easily grasped. Furthermore, by displaying the second objects OJ2 while changing the display mode, it is possible to clearly indicate that the first object OJ1 is not part of the target space SP indicated by the spatial image G1. Therefore, it is possible to easily grasp that the first object OJ1 is an object indicating the air quality state. Therefore, it is possible to easily grasp the multiple types of air quality states, and to allow the user P to visually recognize the overall air quality state considering the multiple air quality states.

[0131] The display step displays the second objects OJ2 such that at least a portion of the second objects OJ2 overlap with another second object OJ2.

[0132] This allows multiple types of air quality conditions to be displayed in a narrower range than when the second object OJ2 is not superimposed, making it easier for the user to grasp multiple types of air quality conditions than when the second object OJ2 is not superimposed.

[0133] The display step displays the second object OJ2 by ​​flickering the outer edge OE of the second object OJ2.

[0134] According to this, since the first object OJ1 can be displayed as an object imitating air, it is possible to easily understand that the first object OJ1 indicates the state of air quality. Therefore, it is possible to more easily understand the state of multiple types of air quality. Furthermore, since the overlapping points of the second objects OJ2 can be changed over time, it is easy to visually recognize the evaluation results of each of the air quality states. Therefore, it is possible for the user to easily visually recognize the overall state of air quality that takes into account the state of multiple types of air quality.

[0135] The degree of fluctuation of the outer edge OE of the second object OJ2 depends on the wind speed in the vicinity where the air quality sensor 2 is provided.

[0136] This allows the user to grasp the state of the air quality, as well as the wind speed around the first object OJ1.

[0137] The display step displays an alert AR in association with the first object OJ1 when the detection value of the air quality sensor 2 includes a detection value equal to or greater than a threshold value.

[0138] This allows the user to understand that they should pay attention to the state of air quality.

[0139] The air quality sensor 2 detects the concentration of air pollutants that pollute the air in the target space SP. The display step displays a third object OJ3 representing the air pollutant in the second object OJ2 for a number of objects corresponding to the concentration of the air pollutant detected by the air quality sensor 2.

[0140] This makes it possible to easily grasp the concentration of air pollutants that pollute the air in the target space SP.

[0141] The air quality sensor 2 is provided in each of a plurality of areas ER in the target space SP. The display step displays a first object OJ1 in each of the plurality of areas ER in the target space SP shown by the spatial image G1.

[0142] This allows the user P to easily grasp multiple types of air quality conditions for each area ER, and also allows the user P to visually recognize the overall air quality condition for each area ER taking into account the multiple air quality conditions.

[0143] The display step displays an area image G2 showing a plurality of areas ER. When any one of the plurality of areas ER is selected in the area image G2, the display step displays the detection value of the air quality sensor 2 installed in the selected area ER for each type of air quality.

[0144] According to this, the detection values ​​of the air quality sensor 2 are displayed for each type of air quality, so that the detection values ​​of the air quality sensor 2 installed in the selected area ER can be specifically understood for each type of air quality.

[0145] The terminal device 1 includes a display control unit 103 that displays a first object OJ1 indicating the state of air quality on the spatial image G1 showing the target space SP using the touch panel 12, based on the detection value of an air quality sensor 2 that detects the state of air quality in the target space SP and on the evaluation result of an evaluation unit 102 that evaluates the state of air quality for each type of air quality. The first object OJ1 is a combination of a plurality of second objects OJ2 indicating the state of air quality for each type of air quality. The display control unit 103 displays the second object OJ2 in a color corresponding to the evaluation result of the evaluation unit 102 for each second object OJ2, and changes the display mode for each second object OJ2.

[0146] This provides the same effects as the above-mentioned display method.

[0147] The display system 1000 includes a touch panel 12, an evaluation unit 102 that evaluates the state of air quality for each type of air quality based on the detection value of an air quality sensor 2 that detects the state of air quality in the target space SP, and a display control unit 103 that displays a first object OJ1 indicating the state of air quality on a space image G1 showing the target space SP based on the evaluation result of the evaluation unit 102, using the touch panel 12.

The display control unit 103 displays the second object OJ2 in a color corresponding to the evaluation result of the evaluation unit 102 for each second object OJ2, and changes the display mode for each second object OJ2.

[0148] This provides the same effects as the above-mentioned display method.

[0149] The display application 111 causes the terminal processor 100 of the terminal device 1 to function as a display control unit 103 that displays, on the touch panel 12, a first object OJ1 indicating the state of air quality in a spatial image G1 showing the target space SP based on the detection value of an air quality sensor 2 that detects the state of air quality in the target space SP and on the evaluation result of an evaluation unit 102 that evaluates the state of air quality for each type of air quality.
