[5. Operation of Information Providing System]
FIG. 3 is a flowchart showing the operation of the information providing system 1000, showing the operation of the information providing server 100 acquiring the operation start time 132. As shown in FIG. The operations of steps SA11 and SA12 are executed by the acquisition unit 122. FIG.

The information providing server 100 waits for the start of operation of the air purifier 10 managed by the information providing server 100 (step SA11). At step SA11, the information providing server 100 determines whether or not there is an input indicating that the operation of the air purification device 10 has been started, and if there is no input (step SA11; NO), it waits.

When the information providing server 100 detects that the operation of the air purification device 10 has started (step SA11; YES), the information providing server 100 acquires the operation start time of the air purification device 10, The operation start time 132 is stored in the memory 130 in association with the target space 1 to be air cleaned by the device 10 (step SA12).

The operation of step SA11 is, for example, to acquire the driving start time input in the tablet PC 4. FIG. In this case, the information providing server 100 detects the start of operation of the air cleaner 10 by accepting the information input by the tablet PC 4 in step SA11. Based on the information input from the tablet PC 4, the information providing server 100 identifies the target space 1 to be air-cleaned by the air purifier 10 that has started operating. The information providing server 100 stores the driving start time acquired from the tablet PC 4 in the memory 130 at step SA12.

Further, the operation of step SA11 may be acquisition of the operating state of the air cleaner 10 via the communication network N, for example. In this case, the information providing server 100 detects the start of operation of the air purification device 10 by accepting the information transmitted by the air purification device 10 in step SA11. The information providing server 100 specifies the target space 1 to be air-cleaned by the air purifying device 10 that has started operating, based on the information transmitted by the air purifying device 10 . The information providing server 100 causes the memory 130 to store the time at which the information is received from the air purifier 10 as the operation start time 132 in step SA12.

FIG. 4 is a sequence diagram showing the operation of the information providing system 1000, and shows the operations of the information providing server 100 and the tablet PC 200 for displaying the information providing screen on the tablet PC 200. FIG. Steps SA21 to SA24 are executed by reception unit 121. FIG. Steps SB11 to SB17 are executed by the acquisition unit 221, and steps SB18 to SB22 are executed by the display control unit 222. FIG.

Tablet PC 200 executes application program 232 in response to a user's operation on touch panel 201, and starts information providing processing (step SB11). The tablet PC 200 requests the information providing server 100 for the operation start time (step SB12).

The information providing server 100 receives the request transmitted by the tablet PC 200 (step SA21), and transmits the requested driving start time 132 to the tablet PC 200 (step SA22). The operation start time 132 transmitted by the information providing server 100 in step SA22 corresponds to the target space 1 in which the tablet PC 200 is installed. Specifically, it is the operation start time 132 stored in the memory 130 in association with the air purification device 10 that cleans the target space 1 in which the tablet PC 200 is installed. The tablet PC 200 of this embodiment is installed in the target space 1A for operation by a user who uses the target space 1A. Therefore, at step SA22, the information providing server 100 transmits the operation start time 132 of the air purification device 10A.

Tablet PC 200 receives and acquires operation start time 132 from information providing server 100 (step SB14). The tablet PC 200 calculates the operation time of the air purifier 10 in units of predetermined time based on the operation start time 132 and the current time (step SB14). The predetermined time unit is 10 minutes, 15 minutes, or other units, and is set in the application program 232 in advance.

Tablet PC 200 determines whether or not the driving time calculated in step SB15 is equal to or greater than the first threshold (step SB15). The first threshold time is set in the application program 232 in advance. The first threshold time is, for example, the time during which a favorable air cleaning effect can be expected by operating the air cleaning device 10A. In other words, if the operating time is equal to or longer than the first threshold time, it can be said that the effect of operating the air purification device 10A is remarkable. The first threshold corresponds to an example of a predetermined threshold.

When determining that the operating time is shorter than the first threshold time (step SB15; NO), tablet PC 200 ends this process. In this case, tablet PC 200 executes the function of application program 232 that is different from the function of displaying the information providing screen.

When the tablet PC 200 determines that the driving time is equal to or longer than the first threshold time (step SB15; YES), the tablet PC 200 requests the information providing server 100 for the reference data 133 (step SB16).

Information providing server 100 accepts the request transmitted by tablet PC 200 (step SA23), and transmits the requested reference data 133 to tablet PC 200 (step SA24). The reference data 133 transmitted by the information providing server 100 in step SA24 corresponds to the target space 1 in which the tablet PC 200 is installed. That is, it is the reference data 133 stored in the memory 130 in association with the air purification device 10 that cleans the target space 1 in which the tablet PC 200 is installed.

Tablet PC 200 receives and acquires reference data 133 transmitted by information providing server 100 (step SB17). Tablet PC 200 selects the display mode of the information provision screen based on the driving time calculated in step SB14 (step SB18).

Tablet PC 200 generates a first display object and a second display object to be arranged on the information providing screen based on the driving time calculated in step SB14 and reference data 133 (step SB19).
Tablet PC 200 generates an animation of the third display object in accordance with the driving time calculated in step SB14 (step SB20).

Tablet PC 200 generates an information providing screen including animation of the first display object, second display object, and third display object (step SB21), and displays the information providing screen on touch panel 201 (step SB22).

[6. Information provision screen configuration]
FIG. 5 is a diagram showing an example of a screen displayed prior to the information provision screen. 6, 7, 8, and 9 are diagrams showing examples of display states on the information providing screen 410. FIG. The initial screen 401 and the information providing screen 410 are displayed on the touch panel 201 in step SB22 of FIG.

An initial screen 401 shown in FIG. 5 is a screen for displaying an information providing screen 410 . Initial screen 401 includes initial message 402 and button 403 . The initial message 402 is a character string that notifies the user that the air purifier 10 is in operation in the target space 1 and prompts the user to check the air condition in the target space 1 .

Here, when the user operates the button 403, the display control unit 222 causes the display of the touch panel 201 to transition to the information providing screen 410 shown in FIG.

Information provision screen 410 includes an animation display. 6 to 9 show the process of changing the information providing screen 410. FIG.
The information providing screen 410 includes a graph display portion 411 . In the graph display section 411, the vertical axis indicates the number of airborne bacteria in the target space 1, and the horizontal axis indicates the passage of time. In the examples of FIGS. 6 to 11, the unit of the vertical axis is CFU (Colony Forming Unit)/100L (100L is 0.1 m ³ ), and the unit of the horizontal axis is minute. The information provision screen 410 corresponds to an example in which the operating time of the air purification device 10 is calculated in units of 10 minutes. The time point 0, which is the starting point of the horizontal axis of the graph display portion 411, is the operation start time of the air purifier 10. FIG.

The graph display section 411 displays a first graph 412 and a second graph 413 as data series. A first graph 412 shows how the number of airborne bacteria changes over time due to natural decrease. A first graph 412 corresponds to an example of a first display object showing a change over time in the survival state of pathogens due to the natural reduction of pathogens floating in the air in space.
A second graph 413 shows how the number of airborne bacteria decreases due to the operation of the air cleaner 10 . A second graph 413 corresponds to an example of a second display object showing the change over time of the residual state of pathogens when the air purifier 10 is operated in space.

The first graph 412 and the second graph 413 are not actual measurements of the number of airborne bacteria in the target space 1 in which the air purifying device 10 is installed, but in the test environment, as a general method for evaluating the degree of airborne microbial contamination. , are the results measured using a bacterial floating amount measuring means. Although the airborne microbial contamination level is generally evaluated by the number of falling bacteria or the number of airborne bacteria, it is difficult to measure the airborne microbial contamination immediately and highly accurately in the space actually used by the user. On the other hand, by using a method of reproducing and verifying the space used by the user in a test environment, highly accurate measurements can be performed, and the state of the actual space can be estimated with high reproducibility.

Thus, the first graph 412 is a graph showing airborne bacteria count measurements in a test space in which the air purification device 10 or similar device is not in operation. A second graph 413 is a graph showing measured values of the number of airborne bacteria in the test space when the air purifier 10 or similar device is operated in the test space. The first graph 412 and the second graph 413 are, for example, graphs obtained by plotting a plurality of measured values in the plot area of the graph display section 411 and connecting them. By displaying the first graph 412 and the second graph 413 corresponding to the common vertical axis and horizontal axis on the graph display unit 411, the user can intuitively understand the effect of operating the air purification device 10. It can be shown clearly.

The measured values and graph data forming the first graph 412 and the second graph 413 are included in the reference data 133 transmitted by the information providing server 100 . That is, the reference data 133 includes measured values of the number of airborne bacteria corresponding to the elapsed time.

A change in the number of airborne bacteria when the air purifying device 10 is operated in a certain space varies depending on the volume of the space, the specifications of the air purifying device 10, the performance of the air purifying device 10, and the like. Therefore, the information providing server 100 stores reference data 133 corresponding to the volume, floor area, specifications of the air purifier 10, etc. of the target space 1 in which the information providing screen 410 is to be displayed. The information providing server 100 transmits the reference data 133 corresponding to the target space 1 in which the device displaying the information providing screen 410 is installed to the television 15, the tablet PC 200, or the smartphone 300.

The operating time is displayed on the horizontal axis of the graph display portion 411 . This display displays the time in units of 60 minutes, for example, so that the user can easily understand it intuitively. This display may be made in units of one hour.

In the graph display portion 411, attribute displays 414a and 414b are displayed at positions corresponding to the first graph 412 and the second graph 413, respectively. Attribute displays 414a and 414b indicate to the user that the first graph 412 indicates changes in the number of airborne bacteria due to natural decrease, and that the second graph 413 indicates changes in the number of airborne bacteria due to operation of the air purification device 10. to notify.

A start time notifying section 418 is also displayed on the information providing screen 410 . The start time notification unit 418 notifies the user of the operation start time of the air purification device 10 .

An animation 415 is displayed in the graph display portion 411 . The animation 415 is an image showing the passage of time from the start of operation of the air purification device 10 to the display of the information provision screen 410 . The initial size of animation 415 may be the size shown in FIG. 6 or may be smaller. In this embodiment, the animation 415 is an arrow, which changes to extend to the right from 0 minutes on the graph display section 411 so as to indicate the passage of time. That is, the animation 415 is an image that changes from a predetermined size to a size corresponding to the length of the operation time of the air purification device 10, and corresponds to an example of a third display object in the present disclosure.

7 and 8 show one process of changing the animation 415. FIG. In FIG. 7, the animation 415 stretches along the horizontal axis from the state of FIG. 6 to indicate to the user that time has elapsed. In FIG. 8, the animation 415 has stretched further along the horizontal axis from the state of FIG. 7, indicating to the user that time has elapsed.

FIG. 9 shows a state in which the animation 415 stops changing. A time display bar 416 indicating the end point of the animation 415 is displayed in the graph display portion 411 . The time display bar 416 is displayed on the horizontal axis of the graph display portion 411 at a position corresponding to the end point of the operating time of the air purification device 10 . That is, the time display bar 416 indicates the display time of the information provision screen 410 in comparison with the operation start time of the air purification device 10 . As a result, the user can be notified of the time when the air cleaning device 10 cleaned the air as the position on the graph display section 411 .

A current time display portion 417 is displayed on the information providing screen 410 at a position corresponding to the time display bar 416 . A current time display unit 417 notifies the user of the current time. The current time is the time when the information provision screen 410 is displayed.

As the animation 415 finishes changing, the information providing screen 410 displays a guide display portion 419 . The guide display part 419 is a character string indicating a message, for example. The content of the message on the guide display unit 419 notifies that the air cleaning has been performed by the air cleaning device 10 in the target space 1 and the effect of the air cleaning. Here, the effect notified by the guidance display unit 419 is the result of verification performed in the test environment, as with the first graph 412 and the second graph 413 . The guidance display portion 419 explicitly indicates that the result of the verification performed in the test environment is communicated.

6 to 9 show examples in which the animation 415 changes over time, while the first graph 412 and the second graph 413 are fixed in display state. This is an example, and the display of the first graph 412 and the second graph 413 may not be fixed.

That is, as a first display example, the information providing system 1000 fixes the first graph 412 and the second graph 413 to the graph display section 411 on the information providing screen 410 as shown in FIGS. and display animation 415 as an animation that changes over time. The timing at which the first graph 412 and the second graph 413 are displayed may be when the information providing screen 410 starts to be displayed, or may be at a predetermined timing while the animation 415 is changing.

As a second display example, the information providing system 1000 may display either or both of the first graph 412 and the second graph 413 as an animation that changes over time. Specifically, at least one of the first graph 412 and the second graph 413 is displayed so as to expand in size along the time axis, starting at 0 minutes on the time axis of the graph display section 411. be. The animation display of the first graph 412 and the second graph 413 may change stepwise or may change smoothly.

In the second display example, the animation display timing of the first graph 412 and the second graph 413 may coincide with the animation display timing of the animation 415 . For example, at least one of the first graph 412 and the second graph 413 and the animation 415 may start changing display at the same time when the information providing screen 410 starts to be displayed. Also, the timing of displaying the animation of the first graph 412 and the second graph 413 may be different from the timing of displaying the animation 415 . For example, after the display of the information provision screen 410 is started, at least one of the first graph 412 and the second graph 413 is first displayed as an animation, and after the display is finished or at a predetermined timing during the display, the animation 415 is displayed. May initiate display changes. Of course, display in the reverse order is also possible.

The information provision screen 410 shown in FIGS. 6 to 9 is a first display mode of the information provision screen 410. FIG. The first display mode is selected when the operation time of the air purifying device 10 is equal to or greater than the above-described first threshold value and is equal to or less than 480 minutes. In the first display mode, the horizontal axis of the graph display portion 411 indicates time from 0 minutes to 480 minutes.

FIG. 10 is a diagram showing another example of the information providing screen 410, showing a second display mode of the information providing screen 410. As shown in FIG. In the second display mode, the horizontal axis of the graph display portion 411 indicates time from 0 minutes to 540 minutes. The second display mode is selected when the operation time of the air purification device 10 exceeds 480 minutes and is 540 minutes or less.

In the example of FIG. 10, the operating time of the air purification device 10 is 540 minutes. The graph display portion 411 displays a first graph 412 and a second graph 413 for 540 minutes after the start of operation. The guidance display portion 419 is a character string indicating the effect of the operation of the air purification device 10 for 9 hours. Further, when the second display mode is selected in step SB18, the graph display unit 411 sets the maximum value to 540 minutes while the size of the animation 415 changes, that is, in the process shown in FIGS. displayed on a scale that The first graph 412 and the second graph 413 are displayed up to the position of the time display bar 416 .

FIG. 11 is a diagram showing still another example of the information providing screen 410, showing a third display mode of the information providing screen 410. As shown in FIG. In the third display mode, the horizontal axis of the graph display portion 411 indicates time from 0 minutes to 540 minutes, as in the second display mode. The third display mode is selected when the operating time of the air cleaner 10 exceeds 540 minutes. When the third display mode is selected in step SB18, the graph display portion 411 is displayed on a scale with a maximum value of 540 minutes while the size of the animation 415 changes.

As shown in FIGS. 6 to 11, it has been confirmed in a test environment that the air cleaner 10 of this embodiment reduces the number of airborne bacteria by 99.9% after 9 hours of operation. Therefore, it is preferable to display the second graph 413 with 9 hours as the upper limit from the viewpoint of display effect and user convenience.

In the example of FIG. 11, the time display bar 416 is displayed at the position of 540 minutes, which is the upper limit of the display. In this example, the operating time of the air purification device 10 exceeds the display upper limit, so the current time and the display of the graph display section 411 do not match. Therefore, the display of the current time display section 417 is omitted. Further, the guidance display portion 419 is a character string indicating the effect when the air purification device 10 is operated for 9 hours or longer.

6 to 11, for example, when the user enters the target space 1 and causes the information providing screen 410 to be displayed on the television 15, the touch panel 201, or the touch panel 301, the air purification device 10 is in operation. displayed if The mode of operation of the air purification device 10 is not limited to such an example. For example, as a first operation mode of the air purifier 10, there is a mode in which the air purifier 10 performs an operation for purifying the air in the target space 1 for a preset time and then automatically stops. Further, as a second operation mode of the air purifying device 10, after the air purifying device 10 executes the operation for purifying the air in the target space 1, an operation to stop the air purifying device 10 by a person in charge of performing maintenance or the like is performed. The mode performed is mentioned. In these aspects, there is a possibility that the operation of the air purification device 10 has stopped at the timing when the information providing screen 410 is displayed on the television 15, the touch panel 201, or the touch panel 301.

If the air purification device 10 has stopped operating when the information provision screen 410 is displayed, the information provision screen 410 may display that the air in the target space 1 has already been purified by the air purification device 10. good. For example, assume an example in which the air purifier 10 runs for 9 hours from 10:00 to 19:00 and then stops, and the information provision screen 410 is displayed at 20:00. In this case, on the information providing screen 410, for example, it is conceivable to display a character string such as "19:00 sterilization completed" indicating that sterilization is completed at 19:00. This character string is displayed in place of, for example, the current time display section 417 in FIGS.

Further, after the air purification device 10 has been operated in the first operation mode or the second operation mode, the information providing server 100 operates the remote controller 11 to operate the remote controller 11 while the air purification device 10 is stopped. It may be detected that the purification device 10 has started operation. In this case, the information providing server 100 may detect that the air purifier 10 has started operating and display the information providing screen 410 on the television 15 or the touch panel 201 . The information providing server 100 may also send a push notification to the smartphone 300 to display the information providing screen 410 on the touch panel 301 . The operation of the information providing server 100 detecting the start of operation of the air purifier 10 may be the same as step SA11, for example.
The information providing screen 410 displayed in this case may include a character string or the like indicating that the air in the target space 1 has already been purified by the air purification device 10 as described above.
Here, the timing at which the information provision screen 410 is displayed may be rephrased as, for example, the timing at which the display object of the information provision screen 410 is generated.

Thus, in the information providing system 1000, the information providing screen 410 notifies the air condition in the target space 1 in which the air purification device 10 is installed. The display mode of the information providing screen 410 is selected from first, second and third display modes according to the operation time of the air purification device 10 . In the first, second, and third display modes, the range of the length of driving time to be applied is determined, and the third display mode corresponding to the range of the longest driving time is displayed in the graph display section 411. A maximum driving time is established. The upper limit of the operating time is the time at which the effect of operating the air purifying device 10 can be considered to be substantially constant at the maximum value based on the verification results in the test environment. At step SB18 (FIG. 4), one of the first, second and third display modes is selected based on the operating time of the air cleaner 10. FIG.

6 to 11 are only examples of the configuration of the information providing screen 410, and the information displayed on the information providing screen 410 can be changed as appropriate. For example, the scale of the horizontal axis of the graph display section 411 may be determined according to the volume or floor area of the target space 1 and the capacity of the air purifying device 10, and the operating time of the air purifying device 10 is indicated in units of one minute, The maximum value on the horizontal axis may be 20 minutes. In addition, for example, the guide display section 419 may include information explaining the method by which the air purifying device 10 cleans the air and the product name of the air purifying device 10 .

The initial screen 401 shown in FIG. 5 and the information providing screen 410 shown in FIGS. These operations will be described below.

[7. Operation of other display devices]
FIG. 12 is a flowchart showing the operation of the information providing system 1000, and shows the operation of the information providing server 100 when the television 15 displays the initial screen 401 and the information providing screen 410. FIG.

The display control unit 123 detects that the power of the television 15 has been switched on (step SA31). The display control unit 123 acquires from the memory 130 the operation start time 132 of the air purification device 10 that cleans the air in the target space 1 in which the television 15 is installed (step SA32).

The display control unit 123 calculates the operation time of the air purification device 10 in units of a predetermined time based on the operation start time 132 and the current time (step SA33). The predetermined time unit is 10 minutes, 15 minutes, or other units, and is set in the control program 131 in advance.

The display control unit 123 determines whether or not the operating time calculated in step SA33 is equal to or greater than the first threshold (step SA34).

When the display control unit 123 determines that the operating time is equal to or longer than the first threshold time (step SA34; YES), the display control unit 123 acquires the reference data 133 from the memory 130 (step SA35). The display control unit 123 selects the display mode of the information providing screen based on the driving time calculated in step SA33 (step SA36).

The display control unit 123 generates a first display object and a second display object to be arranged on the information providing screen based on the driving time calculated in step SA33 and the reference data 133 (step SA37). The display control unit 123 generates animation of the third display object according to the driving time calculated in step SA33 (step SA38).

The display control unit 123 generates an information providing screen including animations of the first display object, the second display object, and the third display object (step SA39). Display control unit 123 transmits display data including an information providing screen to television 15 (step SA40), and causes display screen 16 to display the information providing screen (step SA41).

When the display control unit 123 determines that the driving time is shorter than the first threshold time (step SA34; NO), the display control unit 123 generates display data that does not include the information providing screen and transmits the display data to the television 15 (step SA42). The process proceeds to step SA41. The display data generated in step SA42 is, for example, data for displaying a screen for notifying the user who uses the target space 1B of hotel information and the like.

FIG. 13 is a sequence diagram showing operations of the information providing server 100, and shows operations of the information providing server 100, the reservation management server 3, and the smartphone 300. As shown in FIG. The operation in FIG. 13 is an operation in which the user who has reserved the guest room operates the smartphone 300 to check in when the information providing server 100 manages the target space 1, which is a hotel guest room. The information providing system 1000 causes the smartphone 300 to display an information providing screen when the user enters the target space 1 after checking into the hotel.

In FIG. 13, steps SA51-SA55 are executed by the reception unit 121 of the information providing server 100, and steps SC11-SC14 are executed by the reservation management server 3. FIG. Steps SD11 to SD14 are executed by the reservation processing unit 321 of the smartphone 300, and step SD15 is executed by the acquisition unit 322 and the display control unit 323.

The process of FIG. 13 is executed after the user operating smartphone 300 has made a hotel reservation. Smartphone 300 transmits a check-in request to reservation management server 3 in response to an operation on touch panel 301 (step SD11).

The reservation management server 3 receives the check-in request from the smartphone 300 (step SC11), and executes check-in processing based on the request (step SC12). In step SC12, the reservation management server 3 confirms the reservation of the user operating the smartphone 300, determines the room to be used by the user, and the like. The reservation management server 3 transmits the result of the check-in process to the smart phone 300 (step SC13). In step SC13, the reservation management server 3, for example, notifies the smartphone 300 of the room number used by the user.

Smartphone 300 receives the processing result from reservation management server 3 (step SD12), and displays the received processing result on touch panel 301 (step SD13). As a result, the user is notified of the room number and the like.

The reservation management server 3 transmits check-in information indicating that the check-in process for the user using the smartphone 300 has been performed to the information providing server 100 (step SC14). The check-in information includes information such as the room number used by the user and information for executing communication with the smartphone 300 used by the user who has checked in.

The information providing server 100 receives the check-in information from the reservation management server 3 (step SA51), and identifies the target space 1 where the check-in has been performed (step SA52).

The information providing server 100 monitors the detection state of the door sensor 12 of the target space 1 where check-in has been performed, and detects that the door is open (step SA53). After detecting that the door of target space 1 has been opened, information providing server 100 notifies smartphone 300 of the start of information providing processing (step SA54). In response, smartphone 300 receives the notification transmitted by information providing server 100 (step SD14).

Thereafter, information providing server 100 executes information providing processing (step SA54), and smart phone 300 executes information providing processing according to the operation of information providing server 100 (step SD15).

The information providing process is the same as the operation described with reference to FIG.
At step SA54, the reception unit 121 of the information providing server 100 executes the operations of steps SA21 to SA24 of FIG. In step SD15, the acquisition unit 322 of the smartphone 300 performs the operations of steps SB11 to SB17 in FIG. 4, and the display control unit 323 performs the operations of steps SB18 to SB22. As a result, the information providing screen 410 shown in FIGS. 5 to 9, the information providing screen 410 shown in FIG. 10, or the information providing screen 410 shown in FIG.

[8. effects, etc.]
As described above, in this embodiment, the information providing system 1000 includes a display device. The information providing system 1000 includes a first display object that shows the change over time in the remaining state of pathogens due to the natural decrease of pathogens floating in the air in the space, and the change over time in the remaining state of pathogens when the air purifier 10 is operated in the space. An information provision screen 410 including a second display object indicating the change and a third display object indicating the operating time of the air purification device 10 is displayed by the display device. The display devices are the television 15, the tablet PC 200, and the smart phone 300, for example.
Thereby, it is possible to provide the user who uses the target space 1 with visual information regarding the reduction of pathogens in the target space 1 . Accordingly, it is possible to more intuitively convey to the user information regarding the state of the space in which the air is to be cleaned.

The information providing method using the information providing server 100, the tablet PC 200, or the smartphone 300 of the present embodiment includes a first display object showing the change over time in the remaining state of pathogens due to the natural decrease of pathogens floating in the air in the space, and An information providing screen 410 including a second display object indicating a change over time in the residual state of pathogens when the air purifying device 10 is operated and a third display object indicating the operation time of the air purifying device 10 is displayed by a display device. indicate.
According to this information providing method, it is possible to provide users using the target space 1 with visual information regarding the reduction of pathogens in the target space 1 . Accordingly, it is possible to more intuitively convey to the user information regarding the state of the space in which the air is to be cleaned.
This information providing method specifically corresponds to the method of causing the information providing server 100 to display the information providing screen 410 on the television 15 in this embodiment. It also corresponds to a method by which the control unit 210 causes the touch panel 201 to display the information provision screen 410 and a method by which the control unit 310 causes the touch panel 301 to display the information provision screen 410 .

The control program 131 and the application programs 232 and 332 of this embodiment are programs that can be executed by a computer. These programs are executed by a computer to display a first display object showing a change over time in the residual state of pathogens due to the natural reduction of pathogens floating in the air in the air, and a residual state of pathogens when the air purifier 10 is operated in the space. An information provision screen 410 including a second display object indicating the change over time of the air purifier 10 and a third display object indicating the operation time of the air purifier 10 is displayed on the display screen.
By executing this program on a computer, a user using the target space 1 can be provided with visual information regarding the reduction of pathogens in the target space 1 by means of a display device. Accordingly, it is possible to more intuitively convey to the user information regarding the state of the space in which the air is to be cleaned. Specifically, this configuration corresponds to the operation of displaying the information providing screen 410 on the television 15 by the processor 120 executing the control program 131 in this embodiment. The processor 220 executes the application program 232 to display the information providing screen 410 on the touch panel 201, and the processor 320 executes the application program 332 to display the information providing screen 410 on the touch panel 301. It corresponds to the above configuration.

As in this embodiment, the information providing system 1000 does not display the information providing screen 410 when the driving time is shorter than the first threshold. For example, the information providing system 1000 does not display the information providing screen 410 on the television 15, the touch panel 201, the touch panel 301, and the like. Further, the initial screen 401 may not be displayed when the operating time is shorter than the first threshold. As a result, information that makes it difficult for the user to recognize the effects of the air purifying device 10 is not provided, so that convenience for the user is not impaired.

As in the present embodiment, the information providing system 1000 includes an acquisition unit 122 that acquires the operation start time of the air purifier 10, the operation time is calculated based on the operation start time, and the first display object corresponding to the operation time and and a display control unit 123 that generates a second display object and causes the television 15 to display the information providing screen 410 .
