Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. Note that the following examples are an example of embodying the present disclosure and do not limit the technical scope of the present disclosure. Also, throughout all the drawings, the same parts are denoted by the same reference numerals and the description thereof is omitted. Further, for the details of each part not directly related to the present disclosure, the description for each drawing is omitted in order to avoid duplication.

[0011] Also, each drawing is a schematic diagram and is not necessarily drawn precisely. Therefore, for example, the scales etc. in each drawing do not necessarily match. Also, in each drawing, substantially the same configurations are denoted by the same reference numerals, and overlapping descriptions are omitted or simplified.

[0012] <First Embodiment> Hereinafter, the first embodiment which is a premise example of the present disclosure will be described in the order of (1) overall configuration, (2) settings for thermal fluid analysis, (3) thermal fluid analysis, (4) conversion of thermal fluid analysis results, and (5) display on the portable information terminal with reference to the drawings.

[0013] (1) Overall configuration FIG. 1 is an overall configuration diagram of a visualization system 1000 according to a first embodiment. The visualization system 1000 performs a thermal fluid analysis calculation of a diffusion substance having a sterilization effect in an analysis space, which is a space to be subjected to thermal fluid analysis, based on analysis condition information, and displays the analysis result. The visualization system 1000 includes an input terminal 100, a processing device 120, a server 200, and a portable information terminal 300. The input terminal 100 includes a setting unit 110, and the setting unit 110 includes an input unit 112 and an output unit 114. The processing device 120 includes an analysis unit 130 and a conversion unit 150. The analysis unit 130 includes an acquisition unit 132, a processing unit 134, a calculation unit 136, a determination unit 138, a storage unit 140, and an analysis result output unit 142, and the conversion unit 150 includes an analysis result acquisition unit 152, a processing unit 154, and an output unit 156. The server 200 includes a database 210. The portable information terminal 300 includes a communication unit 310, a control unit 320, an operation unit 330, a display unit 340, an imaging unit 350, and a storage unit 360.

[0014] The input terminal 100 is a PC (Personal Computer) or a tablet terminal. The input unit 112 is a user interface that receives operations from the user. The user interface is, for example, a touch panel or physical operation buttons. The input unit 112 creates analysis target data based on operations from the user. The analysis target data includes information on the analysis space to be subjected to thermal fluid analysis.

[0015] FIGS. 2(a)-(g) show an overview of the operation of the visualization system 1000. FIG. 2(a) shows an analysis space 10 included in the analysis target data created in the setting unit 110. The analysis space 10 is a virtual space that models an actual space (hereinafter referred to as the "real space") and is a space to be subjected to thermal fluid analysis. The real space is, for example, a living space or an office space in a general house, and the living space or office space may include one or more rooms. Also, devices such as air conditioners and desks are arranged in the analysis space 10 in the same manner as in the real space. The input unit 112 receives information about the devices, such as the model, size, and operating conditions, as device information. The device information is also included in the analysis target data.

[0016] Figure 2(b) shows the marker 20 set in any room of the analysis space 10 shown in Figure 2(a). The input unit 112 places the marker 20 on the analysis space 10 by the user's operation in the analysis target data and specifies the coordinates of the marker 20. The marker 20 will be described later. Figures 2(c)-(g) will be described later, and return to Figure 1. The input unit 112 is communicably connected to the acquisition unit 132 of the analysis unit 130 described later by wireless or wired means.

[0017] The output unit 114 outputs the coordinates of the marker 20 received by the input unit 112 and the device information to the analysis result acquisition unit 152 of the conversion unit 150.

[0018] The processing device 120 is composed of a computer system having a processor and a memory. The analysis unit 130 of the processing device 120 executes a thermal fluid analysis calculation by the processor executing a program stored in the memory based on the analysis target data. The acquisition unit 132 of the analysis unit 130 acquires the analysis target data about the analysis space 10 that is the target of the thermal fluid analysis from the input unit 112. The acquisition unit 132 outputs the analysis target data to the processing unit 134.

[0019] The processing unit 134 causes the calculation unit 136 to execute a thermal fluid analysis calculation in order to simulate the situation where air is blown from the air conditioner arranged in the analysis space 10 based on the analysis target data. The calculation unit 136 performs an analysis based on, for example, computational fluid dynamics (CFD) (hereinafter referred to as CFD analysis). The CFD analysis executes a thermal fluid analysis calculation for the analysis target data by a model such as Reynolds-Averaged Navier-Stokes equations (RANS), Direct Numerical Simulation (DNS), Large Eddy Simulation (LES), or Detached Eddy Simulation (DES).

[0020] For example, based on the type of the diffusing substance, the generation amount of the diffusing substance, the wind direction and wind speed of the airflow, the self-decomposition coefficient of the diffusing substance, the diffusion coefficient of the diffusing substance, the adsorption and desorption coefficient of the diffusing substance, etc., the arithmetic unit 136 executes CFD analysis to calculate the airflow flowing out from the air conditioner at each position in the analysis space 10 and the concentration of the diffusing substance contained in the airflow. Specifically, as shown in FIG. 2(c), the arithmetic unit 136 generates a three-dimensional distribution of the airflow and the diffusing substance concentration at each position in the analysis space 10. Since the self-decomposition coefficient of the diffusing substance, the diffusion coefficient of the diffusing substance, and the adsorption and desorption coefficient of the diffusing substance are known technologies, the description thereof is omitted here.

[0021] The diffusing substance is a substance having a sterilizing action of sterilizing bacteria. Here, sterilization means not only the removal of bacteria or germs but also the removal of viruses and the like. That is, bacteria include not only bacteria but also viruses and the like. Examples of bacteria include, but are not limited to, Staphylococcus aureus, Pseudomonas aeruginosa, or Escherichia coli. An example of the diffusing substance is hypochlorous acid (HClO). Another example of the diffusing substance may be a substance containing OH radicals generated by applying a high voltage to moisture in the air (for example, Nanoe (registered trademark)).

[0022] The determination unit 138 analyzes the thermal fluid analysis result obtained by the arithmetic unit 136 to identify the presence or absence of a distribution region where the result of the analyzed physical property value is outside the reference range (if it is the concentration of the diffusing substance, 4 ppb to 10 ppb). The storage unit 140 stores various types of information. The storage unit 140 stores an algorithm for executing the processing of the processing unit 134 of the present disclosure. The storage unit 140 stores past thermal fluid analysis results and information on each member used in the analysis calculation in the arithmetic unit 136 (model, shape, default conditions, diffusing substance information, etc.). The analysis result output unit 142 outputs the thermal fluid analysis result to the conversion unit 150 in the processing unit 134.

[0023] The analysis result acquisition unit 152 of the conversion unit 150 receives the thermal fluid analysis result from the analysis result output unit 142 and outputs the thermal fluid analysis result to the processing unit 154. Further, the analysis result acquisition unit 152 receives the coordinates of the marker 20 and the device information from the output unit 114 and outputs the coordinates of the marker 20 and the device information to the processing unit 154.

[0024] As shown in FIG. 2(d), the processing unit 154 converts the thermal fluid analysis result 160 into AR data 162. The AR data 162 is data for displaying the thermal fluid analysis result 160 as AR on the portable information terminal 300. Although the data formats of the AR data 162 and the thermal fluid analysis result 160 are different, since the AR data 162 also shows the thermal fluid analysis result, hereinafter, the "AR data 162" may also be referred to as the "thermal fluid analysis result 160". At the time of conversion, the coordinates of the marker 20 and the device information are associated with the AR data 162. That is, in the analysis space 10 (hereinafter, this is also referred to as the "analysis space 10") converted into the AR data 162, the marker 20 is arranged at the same position as before. The output unit 156 can communicate with the server 200 wirelessly or by wire, and transmits the AR data 162 to the server 200.

[0025] The database 210 of the server 200 receives the AR data 162 from the output unit 156. The database 210 stores the AR data 162. The database 210 transmits the AR data 162 to the portable information terminal 300 in response to a request from the portable information terminal 300.

[0026] The portable information terminal 300 is a tablet terminal or a smartphone. Also, the portable information terminal 300 may be in a state of being used as a tablet terminal in a 2-in-1 portable terminal (a terminal that can be used as a notebook computer or a tablet depending on the scene). The portable information terminal 300 may be the same device as the input terminal 100. The communication unit 310 can communicate with the server 200 wirelessly and receives the AR data 162 from the server. The communication unit 310 outputs the AR data 162 to the control unit 320. The control unit 320 executes a program stored in the storage unit 360. Here, a program for visualizing the thermal fluid analysis result 160 by AR is executed. When executing the program, the control unit 320 receives an operation from the user with respect to the operation unit 330. The operation unit 330 is a user interface capable of receiving an operation from the user, and is, for example, a touch panel.

[0027] The imaging unit 350 is a LiDAR (Light Detection and Ranging) camera or a LiDAR sensor. It captures images and determines the distance to the objects included in the captured images. The imaging unit 350 outputs the captured images to the control unit 320. The images include information on the determined distances. The control unit 320 causes the display unit 340 to display the images captured by the imaging unit 350.

[0028] FIG. 2(e) shows the image displayed on the display unit 340. A marker 420 is arranged in the real space corresponding to the analysis space 10. Here, the relative positions of the marker 20 arranged in the analysis space 10 and the marker 420 arranged in the real space 410 are the same. The marker 420 is captured by the imaging unit 350.

[0029] FIG. 2(f) shows the processing in the control unit 320. The control unit 320 specifies the position of the marker 420 in the real space 410 based on the image captured by the imaging unit 350. Also, the control unit 320 specifies the position of the marker 20 in the analysis space 10 based on the AR data 162. The control unit 320 associates the real space 410 coordinates with the analysis space 10 coordinates by associating the marker 420 with the marker 20. That is, the alignment between the real space 410 and the analysis space 10 is performed.

[0030] Thereby, the control unit 320 three-dimensionally displays the real space 410 on the display unit 340 as shown in FIG. 2(g), and also displays the thermal fluid analysis result 160 obtained by the analysis unit 130 by superimposing it on the three-dimensionally displayed real space 410 on the display unit 340.

[0031] (2) Settings for Thermal Fluid Analysis When the user operates the input unit 112 to start work, the input terminal 100 displays the first display screen F1 of FIG. 3 on a display unit (not shown). FIG. 3 illustrates the first display screen F1. On the first display screen F1, the vertex coordinates of the analysis space 10 are input by the user. By specifying the vertex coordinates on the first display screen F1 by the user's operation (e.g., click, etc.), the shape of the analysis space 10 is defined. Here, on the first display screen F1, when the user performs a click C1, the vertex coordinates of the vertex T1 of the analysis space 10 are determined. Subsequently, when the user performs a click C2, the vertex coordinates of the vertex T2 of the analysis space 10 are determined, and a wall W1 connecting the vertex T1 and the vertex T2 is displayed. Thereafter, when the user performs clicks C3 to C6, the vertex coordinates of the vertices T3 to T6 of the analysis space 10 are determined, and walls W2 to W5 connecting the vertex T2 and the vertex T3, the vertex T3 and the vertex T4, the vertex T4 and the vertex T5, and the vertex T5 and the vertex T6 are displayed. Finally, when the user performs a click C7 on the same location as the click C1, i.e., the vertex T1, a wall W6 connecting the vertex T1 and the vertex T6 is displayed, and the shape of the analysis space 10 is defined.

[0032] When the shape of the analysis space 10 is defined, the second display screen F2 shown in FIG. 4 is displayed. FIG. 4 illustrates the second display screen F2. On the second display screen F2, the reference dimension of the analysis space 10 is input by the user. The vertex coordinates can be based on any position on the first display screen F1. When the user performs clicks C11 and C12 on any two locations (e.g., locations where the dimension is known) on the second display screen F2, a reference line L connecting the two locations of the clicks C11 and C12 is displayed. Thereafter, by inputting the value of the reference dimension into the reference dimension input field 31, the dimension of the reference line L is determined, so that the scale between the vertex coordinates determined on the first display screen F1 can be adjusted to the actual dimension. Also, on the second display screen F2, the ceiling height of the analysis space 10 is determined by inputting the ceiling height of the analysis space 10 into the ceiling height input field 32.

[0033] When the input of the reference dimension and the ceiling height is completed, the third display screen F3 shown in Fig. 5(a) is displayed. Figs. 5(a)-(b) illustrate the third display screen F3 and the fourth display screen F4. On the third display screen F3, the user inputs the arrangement of the members to be installed in the analysis space 10. By performing clicks C21 to C24 on the locations where the user wants to arrange the members on the third display screen F3, the locations for arranging the members in the analysis space are specified. Also, after clicking on the third display screen F3, the user can perform a slide operation S1 to arrange a wall in the area specified by the slide operation S1.

[0034] When the arrangement operation on the third display screen F3 is completed, the fourth display screen F4 in Fig. 5(b) is displayed. The details of the equipment or structures arranged on the third display screen F3 are input by the user on the fourth display screen F4. The fourth display screen F4 displays the members to be arranged at the positions of each click C21 to C24 and the slide operation S1 in a list format. For example, in the items of each click C21 to C24, details such as equipment, wind direction, air volume, and concentration (concentration of diffused substances) can be input. For example, when the user clicks on the column of the member of click C24 on the fourth display screen F4, the types of members "Model A", "Model B", "Model C", "door", etc. registered in the storage unit 140 in advance are displayed in a list. The user can input the required equipment in the column of the member of click C24 by selecting any one from these listed member types. Similarly, the details of the wind direction, air volume, and concentration are registered in the storage unit 140 in advance for each type of member. When any of the input fields for the wind direction, air volume, and concentration is clicked, the details registered in advance are displayed in a list by accessing the storage unit 140 from the input unit 112, and the user can select them. The position X in the X direction (the left-right direction in Fig. 5(a)) and the position Y in the Y direction (the up-down direction in Fig. 5(a)) are detected from the coordinates of the location where the user clicks or performs a slide operation, and the position is automatically reflected in each input field. Return to Fig. 1. The information of the analysis space 10 created in this way is included in the above-mentioned analysis target data.

[0035] (3) Thermal fluid analysis The calculation unit 136 performs a thermal fluid analysis calculation in the analysis space 10 based on the data to be analyzed. At this time, the information of each member (model, shape, default conditions, diffused substance information, etc.) stored in the storage unit 140 is used for the thermal fluid analysis calculation. Through the thermal fluid analysis calculation, the calculation unit 136 simulates the airflow flowing out from the air conditioner (air outlet) installed on the analysis space 10 into the analysis space 10, and also simulates the diffused substance with a predetermined concentration contained in the airflow and diffused in the analysis space 10.

[0036] Here, as simulations of the airflow, simulations of the airflow blown out from the air conditioner (air outlet) and simulations of the airflow containing the diffused substance (hypochlorous acid) are performed. The airflow containing the diffused substance (hypochlorous acid) is blown out from, for example, equipment other than the air conditioner (air outlet). Also, in the simulation, the airflow is represented by, for example, a set of vectors representing position, direction, and air volume. On the other hand, in the simulation of the diffused substance, the diffused substance concentration at each position in the analysis space 10 is shown. In these simulations, the thermal fluid analysis results are shown by the coordinates of the analysis space 10.

[0037] In the simulation of the airflow containing the diffused substance (hypochlorous acid), a plurality of simulations may be performed while changing the addition amount of hypochlorous acid. Also, simulations of the airflow containing the diffused substance (nanoe) may be performed. Further, in the simulation of the airflow containing the diffused substance (nanoe), a plurality of simulations may be performed while changing the addition amount of nanoe.

[0038] The calculation unit 136 may perform a thermal fluid analysis calculation for each of different data to be analyzed for the same analysis space 10. Different data to be analyzed are created, for example, by changing the air conditioner (air outlet) or the number of air conditioners (air outlets). The calculation unit 136 associates the thermal fluid analysis results for different data to be analyzed.

[0039] FIG. 6 illustrates the fifth display screen F5. The fifth display screen F5 is displayed on the display unit (not shown) of the input terminal 100 or the display unit (not shown) of the processing device 120. On the fifth display screen F5, the progress of the thermal fluid analysis calculation is shown as the convergence status of the calculated physical property values when the calculation cycle is advanced. Specifically, the convergence status of the thermal fluid calculation for turbulent kinetic energy, turbulent dissipation rate, concentrations of various diffusive substances, flow velocity, etc. is shown.

[0040] FIG. 7 illustrates the sixth display screen F6. The sixth display screen F6 is displayed on the display unit (not shown) of the input terminal 100 or the display unit (not shown) of the processing device 120. On the sixth display screen F6, as a result of the thermal fluid analysis, in particular, the concentration distribution of the diffusive substance is three-dimensionally displayed in the analysis space 10.

[0041] (4) Conversion of Thermal Fluid Analysis Results FIGS. 8(a)-(b) illustrate the operation screen for the conversion unit 150. The operation screen is displayed on the display unit (not shown) of the input terminal 100 or the display unit (not shown) of the processing device 120. As shown in FIG. 8(a), a data reference button 400, a conversion data input field 402, and a conversion button 404 are shown. By clicking the data reference button 400, a list of the thermal fluid analysis results 160 output from the analysis result output unit 142 is displayed. When one of the plurality of thermal fluid analysis results 160 included in the list is selected, as shown in FIG. 8(b), the data name of the thermal fluid analysis result 160 to be converted is shown in the conversion data input field 402. In this state, when the conversion button 404 is clicked, as described above, the processing unit 154 of the conversion unit 150 converts the thermal fluid analysis result 160 into AR data 162.

[0042] (5) Display on the Portable Information Terminal Figs. 9(a)-(b) show the appearance of the portable information terminal 300. The portable information terminal 300 is a tablet terminal including a rectangular flat housing 302 with a side grip portion. Fig. 9(a) shows one side 304 of the housing 302, and Fig. 9(b) shows the back side 306 of the housing 302. The one side 304 and the back side 306 are opposite surfaces, both having a rectangular shape. As shown in Fig. 9(a), a rectangular display unit 340 is provided on one side 304 of the housing 302. The display unit 340 also has the function of a touch panel. As shown in Fig. 9(b), a shooting port 352 of the imaging unit 350 is provided on the back side 306 of the housing 302.

[0043] Figs. 10(a)-(e) show the operation overview of the portable information terminal 300. Figs. 10(a)-(e) show the screen of the display unit 340. In Fig. 10(a), a plurality of icons 430 are shown. By touching the icon 430 of the AR application, the control unit 320 activates the AR application stored in the storage unit 360. Fig. 10(b) shows the initial screen of the activated AR application. A message "Please project the marker with the camera" is displayed in the center. The user who has confirmed this message moves the marker 420 placed in the real space 410 to a position where it can be imaged by the imaging unit 350.

[0044] Subsequently, in Fig. 10(c), the marker 420 placed in the real space 410 is displayed on the display unit 340. In Fig. 10(d), the marker 420 is imaged by the imaging unit 350 in the state of Fig. 10(c). Thereby, as described above, the alignment between the real space 410 and the analysis space 10 is made by the control unit 320. In Fig. 10(e), the wall W, devices, and furniture in the analysis space 10 are displayed in AR.

[0045] Figs. 11(a)-(c) show the screens displayed on the display unit 340. Fig. 11(a) shows the screen layout of the display unit 340 when the AR application is launched on the portable information terminal 300. Here, it shows a situation where while facing the display unit 340 of the portable information terminal 300 towards the user, the left side of the portable information terminal 300 is held with the left hand and the right side is held with the right hand. Also, the portable information terminal 300 is held in a horizontally long orientation. The lower left end portion 500 of the display unit 340 is a position operable by the thumb or any finger of the user's left hand, and the lower right end portion 502 is a position operable by the thumb or any finger of the user's right hand. The portable information terminal 300 may be held with one hand of the user.

[0046] Fig. 11(b) shows the screen of the display unit 340 when the AR application is being executed. The AR application generates an image (hereinafter referred to as a "synthetic image") in which the image of the real space 410 captured by the imaging unit 350 and the thermal fluid analysis result 160 with the real space 410 set as the analysis space 10 are overlaid as AR. At that time, the AR application aligns the coordinates of the image of the real space 410 and the coordinates of the analysis space 10 by aligning the marker 420 and the marker 20. The display unit 340 displays the synthetic image generated by the AR application.

[0047] The display unit 340 superimposes and displays a density ON / OFF switch button 510, an air flow display mode switch button 512, a Before / After switch button 514, a density playback / stop operation control button 520, a reset operation control button 522, an elapsed time 524, and an indicator 530 on the synthetic image. The density ON / OFF switch button 510, the air flow display mode switch button 512, the Before / After switch button 514, the density playback / stop operation control button 520, the reset operation control button 522, and the elapsed time 524 are included in the operation unit 330 in Fig. 1 and receive operations (touch operations) from the user. The operation unit 330 is used to operate the image displayed on the display unit 340, particularly the thermal fluid analysis result 160.

[0048] The concentration ON / OFF switch button 510, the airflow display mode switch button 512, and the Before / After switch button 514 are switch buttons for switching the information to be displayed on the display unit 340. These switch buttons are arranged at the lower left end 500. The concentration playback / stop operation control button 520, the reset operation control button 522, and the elapsed time 524 are operation control buttons for controlling the operation of the thermal fluid analysis result 160 to be displayed on the display unit 340. These operation control buttons are arranged at the lower right end 502. That is, the switch buttons and the operation control buttons that require operation on the premise of holding the portable information terminal 300 with both hands while displaying the composite image as widely as possible are arranged at a minimum near the movable range of the fingers. Also, the switch buttons may be arranged at the lower right end 502 in FIG. 11, and the operation control buttons may be arranged at the lower left end 500.

[0049] The indicator 530 includes a diffusing substance type indicator 532 indicating the type of diffusing substance and an airflow state indicator 534 representing the state of the airflow, and is arranged on the upper right side of the display unit 340. The indicator 530 may be arranged on the upper left side of the display unit 340. The indicator is always displayed while the AR application is being executed. On the other hand, the operation control button can detect the presence or absence of contact of a finger with the display unit 340 within a predetermined time and can switch between display and non-display within the display unit 340. That is, when the operation unit 330 does not detect contact of a finger with the operation control button for a predetermined time, the control unit 320 does not display the operation control button on the display unit 340. On the other hand, when the operation unit 330 detects contact of a finger with the operation control button, the control unit 320 displays the operation control button on the display unit 340. The switching operations by operating each switch button and each operation control button and the notification by the indicator 530 will be described later.

[0050] FIG. 11(c) shows another screen of the display unit 340 when the AR application is being executed. Instead of the density ON / OFF toggle button 510, the airflow display mode toggle button 512, and the Before / After toggle button 514 in FIG. 11(b), the airflow display mode toggle button 512, the dia addition amount display mode toggle button 516, and the nanoe addition amount display mode toggle button 518 are arranged at the lower left end portion 500. The airflow display mode toggle button 512, the dia addition amount display mode toggle button 516, and the nanoe addition amount display mode toggle button 518 are also toggle buttons. "Dia" is a simplified notation for operation and indicates air containing hypochlorous acid as a diffusing substance.

[0051] FIGS. 12(a)-(d) show the screens displayed on the display unit 340 when the gripping direction of the portable information terminal 300 is changed. FIGS. 12(a)-(b) show the situation where the portable information terminal 300 is gripped in a landscape orientation as before. As described above, the density ON / OFF toggle button 510, the airflow display mode toggle button 512, and the Before / After toggle button 514 are arranged at the lower left end portion 500. Also, the density playback / stop operation control button 520, the reset operation control button 522, and the elapsed time 524 are arranged at the lower right end portion 502.

[0052] FIG. 12(c)-(d) shows a situation where the portable information terminal 300 is held in a vertically long orientation, which is different from the previous cases. The portable information terminal 300 is provided with an acceleration sensor (not shown) and a geomagnetic sensor (not shown), and the control unit 320 identifies the orientation of the portable information terminal 300 by combining the detection results of these sensors. When the control unit 320 identifies the vertically long orientation of the portable information terminal 300, it moves the left lower end portion 500 and the right lower end portion 502 to the positions shown in FIG. 12(d). Further, the control unit 320 arranges the switching button and the operation control button at the left lower end portion 500 and the right lower end portion 502 in the same manner as before. As a result, the concentration ON / OFF switching button 510, the airflow display mode switching button 512, and the Before / After switching button 514 are arranged at the left lower end portion 500. Also, the concentration play / stop operation control button 520, the reset operation control button 522, and the elapsed time 524 are arranged at the right lower end portion 502.

[0053] That is, the display unit 340 detects the gripping portion of the housing 302 held by hand, and switches and displays the position where the operation unit 330 is superimposed on the composite image so as to be at the same position with respect to the user's thumb. In this way, the display positions of the control buttons and the operation control buttons change to optimal positions when the portable information terminal 300 is held horizontally and when it is held vertically.

[0054] Hereinafter, the switching button, the operation control button, and the indicator 530 shown in FIGS. 11(b)-(c) will be described in detail. The concentration ON / OFF switching button 510 in FIG. 11(b) is a button for switching whether to display the concentration of the diffused substance (hypochlorous acid) in the thermal fluid analysis result 160. Each time the user touches the concentration ON / OFF switching button 510, the control unit 320 alternately switches the display of the concentration ON / OFF switching button 510 between "Concentration ON" and "Concentration OFF". "Concentration ON" corresponds to displaying the concentration of the diffused substance (hypochlorous acid), and "Concentration OFF" corresponds to not displaying the concentration of the diffused substance (hypochlorous acid).

[0055] The airflow display mode switching button 512 is a button for switching whether to display the airflow in the thermal fluid analysis result 160 and for switching the type of airflow when displaying the airflow. Each time the user touches the airflow display mode switching button 512, the control unit 320 switches the display of the airflow display mode switching button 512 in the order of "Airflow OFF", "Airflow Air", "Airflow Dia", and "Airflow Both".

[0056] "Airflow OFF" corresponds to not displaying the airflow, "Airflow Air" corresponds to displaying the airflow blown out from the air conditioner (air outlet), and "Airflow Dia" corresponds to displaying the airflow containing the diffusing substance (hypochlorous acid). Here, "Airflow Dia" may be blown out from devices other than the air conditioner (air outlet). Also, "Airflow Both" corresponds to displaying the airflow blown out from the air conditioner (air outlet) and the airflow containing the diffusing substance (hypochlorous acid).

[0057] Figs. 13(a)-(h) show the screens displayed on the display unit 340. Fig. 13(a) shows the screen when "Concentration OFF" is set by the concentration ON / OFF switching button 510 and "Airflow OFF" is set by the airflow display mode switching button 512. In this case, the control unit 320 generates a composite image without using the thermal fluid analysis result 160 using only the image of the real space 410 photographed by the imaging unit 350 by the AR application. The display unit 340 displays the image of the real space 410 photographed by the imaging unit 350 as the composite image.

[0058] Fig. 13(b) shows the screen when "Concentration OFF" is set by the concentration ON / OFF switching button 510 and "Airflow Air" is set by the airflow display mode switching button 512. In this case, the control unit 320 generates a composite image by superimposing, as AR, the image of the real space 410 photographed by the imaging unit 350 and the thermal fluid analysis result 160 for the airflow blown out from the air conditioner (air outlet). The display unit 340 displays, as the composite image, the image of the real space 410 photographed by the imaging unit 350 and the air conditioner streamline 550 indicating the airflow blown out from the air conditioner (air outlet).

[0059] FIG. 13(c) shows a screen when "concentration OFF" is set by the concentration ON / OFF switch button 510 and "airflow dia" is set by the airflow display mode switch button 512. In this case, the control unit 320 generates a composite image by superimposing, as AR, an image of the real space 410 captured by the imaging unit 350 and the thermal fluid analysis result 160 for the airflow containing the diffusing substance (hypochlorous acid) using an AR application. The display unit 340 displays, as the composite image, an image of the real space 410 captured by the imaging unit 350 and a diffusing substance streamline 552 indicating the airflow containing the diffusing substance (hypochlorous acid).

[0060] FIG. 13(d) shows a screen when "concentration OFF" is set by the concentration ON / OFF switch button 510 and "both airflows" is set by the airflow display mode switch button 512. In this case, the control unit 320 generates a composite image by superimposing, as AR, an image of the real space 410 captured by the imaging unit 350, the thermal fluid analysis result 160 for the airflow blown out from the air conditioner (air outlet), and the thermal fluid analysis result 160 for the airflow containing the diffusing substance (hypochlorous acid) using an AR application. The display unit 340 displays, as the composite image, an image of the real space 410 captured by the imaging unit 350, an air conditioner streamline 550 indicating the airflow blown out from the air conditioner (air outlet), and a diffusing substance streamline 552 indicating the airflow containing the diffusing substance (hypochlorous acid).

[0061] FIG. 13(e) shows a screen when "concentration ON" is set by the concentration ON / OFF switch button 510 and "airflow OFF" is set by the airflow display mode switch button 512. In this case, the control unit 320 generates a composite image by superimposing, as AR, an image of the real space 410 captured by the imaging unit 350 and the thermal fluid analysis result 160 for the diffusing substance concentration using an AR application. The display unit 340 displays, as the composite image, an image of the real space 410 captured by the imaging unit 350 and a diffusing substance concentration 560 indicating the diffusing substance concentration.

[0062] Here, when generating the composite image, the control unit 320 colors the diffusing substance in the analysis space 10 with a predetermined color on the image of the projected real space 410. Further, the control unit 320 changes the transparency of the color colored according to the concentration of the diffusing substance. At that time, the color may be changed according to the concentration of the diffusing substance. The display unit 340 displays the diffusing substance concentration 560 colored in this way.

[0063] FIG. 13(f) shows a screen when "concentration ON" is set by the concentration ON / OFF switch button 510 and "airflow air" is set by the airflow display mode switch button 512. In this case, the control unit 320 generates a composite image by superimposing, as AR, the image of the real space 410 captured by the imaging unit 350, the thermal fluid analysis result 160 regarding the diffusing substance concentration, and the thermal fluid analysis result 160 regarding the airflow blown out from the air conditioner (air outlet). The display unit 340 displays, as the composite image, the image of the real space 410 captured by the imaging unit 350, the diffusing substance concentration 560 indicating the diffusing substance concentration, and the air conditioner streamline 550 indicating the airflow blown out from the air conditioner (air outlet).

[0064] FIG. 13(g) shows a screen when "concentration ON" is set by the concentration ON / OFF switch button 510 and "airflow dia" is set by the airflow display mode switch button 512. In this case, the control unit 320 generates a composite image by superimposing, as AR, the image of the real space 410 captured by the imaging unit 350, the thermal fluid analysis result 160 regarding the diffusing substance concentration, and the thermal fluid analysis result 160 regarding the airflow containing the diffusing substance (hypochlorous acid). The display unit 340 displays, as the composite image, the image of the real space 410 captured by the imaging unit 350, the diffusing substance concentration 560 indicating the diffusing substance concentration, and the diffusing substance streamline 552 indicating the airflow containing the diffusing substance (hypochlorous acid).

[0065] Figure 13(h) shows the screen when "Concentration ON" is set by the concentration ON / OFF switch button 510 and "Both Airflows" is set by the airflow display mode switch button 512. In this case, the control unit 320 generates a composite image by superimposing, as AR, the image of the real space 410 captured by the imaging unit 350, the thermal fluid analysis result 160 regarding the concentration of the diffusing substance, the thermal fluid analysis result 160 regarding the airflow blown out from the air conditioner (air outlet), and the thermal fluid analysis result 160 regarding the airflow containing the diffusing substance (hypochlorous acid). The display unit 340 displays, as the composite image, the image of the real space 410 captured by the imaging unit 350, the diffusing substance concentration 560 indicating the concentration of the diffusing substance, the air conditioner streamline 550 indicating the airflow blown out from the air conditioner (air outlet), and the diffusing substance streamline 552 indicating the airflow containing the diffusing substance (hypochlorous acid).

[0066] In FIGS. 13(b)-(d) and FIGS. 13(f)-(h), the control unit 320 displays, on the display unit 340, a line segment along the flow direction of the airflow at a constant wind speed or higher starting from the air conditioner (air outlet) so that it can be understood from where and how the airflow, for example, the air conditioner streamline 550 and the diffusing substance streamline 552, flows. Further, the control unit 320 represents the airflow by a line or moving particles (dashed lines) with a high density so that the movement of the airflow can be sensuously conveyed. At this time, the particles are displayed so as to move according to the flow velocity of the airflow. However, the movement of the particles to be moved is set at a speed that can be followed by the eye, not at the actual speed (which is too fast at several m / s). Furthermore, the control unit 320 colors the airflow with a color corresponding to the type of the diffusing substance. For example, the airflow containing the diffusing substance (hypochlorous acid) is shown in green, and the airflow blown out from the air conditioner (air outlet) is shown in white.

[0067] Hereinafter, the display of the air flow, for example, the streamline 550 of the air conditioner and the streamline 552 of the diffused substance will be described in more detail. When the control unit 320 superimposes and displays the image of the real space 410 and the thermal fluid analysis result 160, based on the vectors included in the thermal fluid analysis result 160, the air flow flowing out from the air conditioner (air outlet) is generated as line segments along the flow direction, and this is displayed on the display unit 340. At that time, the control unit 320 specifies the distance between the line segment of the air flow and the portable information terminal 300 based on the distance between the object in the image acquired by the imaging unit 350 and the portable information terminal 300. Further, the control unit 320 changes the length and thickness of the line segment according to the specified distance, that is, the perspective position in the displayed analysis space 10.

[0068] FIG. 14 shows the screen displayed on the display unit 340. Here, the air conditioner streamline 550 and the diffused substance streamline 552 are classified into a near streamline 554 with a relatively short distance from the portable information terminal 300 and a remote streamline 556 with a relatively long distance from the portable information terminal 300. The near streamline 554 corresponds to the air flow close to the viewpoint, and the remote streamline 556 corresponds to the air flow far from the viewpoint. The near streamline 554 is indicated by a thick and long line segment, and the remote streamline 556 is indicated by a thin and short line segment.

[0069] The di - addition amount display mode switching button 516 in FIG. 11(c) is a button for switching the addition amount of the diffused substance (hypochlorous acid) to the air flow. Each time the user touches the di - addition amount display mode switching button 516, the control unit 320 sequentially switches the display of the di - addition amount display mode switching button 516 to "Di OFF", "Di 20", "Di 32", "Di 39". Further, the control unit 320 generates a composite image including the thermal fluid analysis result 160 for the air flow with the changed addition amount of hypochlorous acid by the AR application, and displays the composite image on the display unit 340.

[0070] The nanoe addition amount display mode switching button 518 in Fig. 11(c) is a button for switching the addition amount of the diffusion substance (nanoe) to the air flow. Each time the user touches the nanoe addition amount display mode switching button 518, the control unit 320 switches the display of the nanoe addition amount display mode switching button 518 in the order of "nanoe OFF", "nanoe 10", "nanoe 20", and "nanoe 100". Further, the control unit 320 generates a composite image including the thermal fluid analysis result 160 of the air flow with the changed nanoe addition amount by the AR application, and causes the display unit 340 to display the composite image.

[0071] As described above, the indicator 530 in Fig. 11(b) includes the diffusion substance type indicator 532 and the air flow state indicator 534. "Nanoe" and "Dia" included in the diffusion substance type indicator 532 indicate the types of diffusion substances when the thermal fluid analysis result 160 regarding the diffusion substance concentration is displayed. For example, when the control unit 320 causes the thermal fluid analysis result 160 regarding the concentration of hypochlorous acid to be displayed, the "Dia" part of the diffusion substance type indicator 532 is lit, and the "nanoe" part is turned off.

[0072] "Air", "nanoe", and "Dia" included in the air flow state indicator 534 indicate the types of diffusion substances when the thermal fluid analysis result 160 regarding the air flow is displayed. For example, when the control unit 320 causes the thermal fluid analysis result 160 of the air flow not containing the diffusion substance to be displayed, the "Air" part of the air flow state indicator 534 is lit. When the control unit 320 causes the thermal fluid analysis result 160 of the air flow containing the diffusion substance (nanoe) to be displayed, the "nanoe" part of the air flow state indicator 534 is lit. When the control unit 320 causes the thermal fluid analysis result 160 of the air flow containing the diffusion substance (hypochlorous acid) to be displayed, the "Dia" part of the air flow state indicator 534 is lit.

[0073] Hereinafter, the Before / After switching button 514 shown in FIGS. 11(b)-(c) will be described in detail. The Before / After switching button 514 is a button for switching the thermal fluid analysis results 160 for each of different analysis target data. Each time the user touches the Before / After switching button 514, the control unit 320 alternately switches between "Before" and "After" as the display of the Before / After switching button 514.

[0074] FIGS. 15(a)-(b) show the screens displayed on the display unit 340. FIG. 15(a) shows the screen when "Before" is set by the Before / After switching button 514. FIG. 15(a) is shown in the same manner as before. FIG. 15(b) shows the screen when "After" is set by the Before / After switching button 514. The control unit 320 generates a composite image using the thermal fluid analysis result 160 different from the thermal fluid analysis result 160 for the analysis target data used in FIG. 15(a). Here, a virtual air conditioner 570 is added, and air flow is blown out from the virtual air conditioner 570.

[0075] Hereinafter, the concentration reproduction / stop operation control button 520, reset operation control button 522, and elapsed time 524 shown in FIGS. 11(b)-(c) will be described in detail. Although omitted in the previous description, the thermal fluid analysis result 160 in the arithmetic unit 136 or the composite image in the control unit 320 is not generated for one timing, but is continuously generated at regular intervals over a predetermined time from the start timing. The start timing is defined as the timing when the airflow starts to blow out from the air conditioner (air outlet) or the timing when the attachment of the diffusing substance to the airflow starts. The regular interval is, for example, 1 second interval, 10 second interval, 1 minute interval. Also, the predetermined time is the time until the concentration of the diffusing substance in the analysis space 10 converges. This can also be said to be the time until the variation values of the diffusing substances (diffusing substance 1 to diffusing substance 3) shown in FIG. 6 converge. Convergence is determined by the difference between the average value of the concentration of the diffusing substance in the analysis space 10 at a predetermined timing and the average value of the concentration of the diffusing substance in the analysis space 10 at the timing one after the predetermined timing being within a certain range.

[0076] The concentration reproduction / stop operation control button 520 is a button for instructing whether to display the composite images continuously generated at regular intervals in time series or to stop the display. When the control unit 320 receives a display instruction from the concentration reproduction / stop operation control button 520, it reproduces the composite images in time series and displays them on the display unit 340. At that time, the elapsed time 524 indicates the elapsed time from the start timing.

[0077] Figs. 16(a) - (c) show the screens displayed on the display unit 340. Here, as an example, "Concentration ON" is set by the concentration ON / OFF switching button 510, and "Airflow OFF" is set by the airflow display mode switching button 512. Fig. 16(a) shows the composite image at the start timing. Since it is the start timing, the concentration of the diffusing substance is low. Therefore, the diffusing substance concentration 560 is shown with high transparency. Fig. 16(b) shows the composite image at the timing 5 minutes after the start timing. Since the diffusing substance has been added to the airflow for 5 minutes, the concentration of the diffusing substance has increased. Therefore, the diffusing substance concentration 560 is shown with lower transparency compared to the case of Fig. 16(a). Fig. 16(c) shows the composite image at the timing 10 minutes after the start timing. Since the diffusing substance has been added to the airflow for 10 minutes, the concentration of the diffusing substance has further increased. Therefore, the diffusing substance concentration 560 is shown with lower transparency compared to the case of Fig. 16(b). The same change is shown even when the airflow is included in the composite image.

[0078] In this way, when the display unit 340 superimposes and displays, as AR, the image of the real space 410 captured by the imaging unit 350 and the thermal fluid analysis result 160 with the space set as the analysis space 10, the display unit 340 dynamically displays the state in which the thermal fluid analysis result 160 changes in time series. In particular, the display unit 340 displays, in time series, the results from the start of adding the diffusing substance to the airflow until a predetermined time has elapsed as the thermal fluid analysis result 160.

[0079] The reset operation control button 522 is a button for instructing to return the time when the composite image is being played back to the start timing. It can also be said that this is a button for resetting the elapsed time since the start of adding the diffusing substance to the airflow. When the control unit 320 receives a reset instruction by the reset operation control button 522, the control unit 320 returns the timing for playing back the composite image to the start timing.

[0080] The subject of the device, system, or method in the present disclosure includes a computer. By executing a program on this computer, the functions of the subject of the device, system, or method in the present disclosure are realized. The computer mainly comprises a processor that operates according to the program as its hardware configuration. The type of the processor is not limited as long as it can realize functions by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integration (LSI). The plurality of electronic circuits may be integrated on one chip or provided on a plurality of chips. The plurality of chips may be aggregated in one device or provided in a plurality of devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM, an optical disk, or a hard disk drive. The program may be pre-stored in the recording medium or supplied to the recording medium via a wide-area communication network including the Internet or the like.

[0081] According to the present embodiment, when the image of the real space 410 and the thermal fluid analysis result 160 are overlaid and displayed as AR, the state in which the thermal fluid analysis result 160 changes in time series is dynamically displayed, so that the time-series change of the environment can be notified. Further, when generating the synthetic image, the diffused substance is colored in a predetermined color on the projected image of the real space 410, and the transparency of the color colored according to the concentration of the diffused substance is changed, so that the spatial concentration distribution of the diffused substance can be visualized. Further, since the airflow is colored and displayed in a predetermined color and a predetermined density according to the concentration of the diffused substance, the state of the airflow can be visualized. Further, since the results until a predetermined time elapses after starting the addition of the diffused substance to the airflow are displayed in time series, the understanding degree of the time change of the spatial concentration distribution can be improved. Further, since the predetermined time is the time until the concentration of the diffused substance converges, the time change of the concentration of the diffused substance can be notified.

[0082] In addition, since the diffusing substance contains any one of hypochlorous acid and a substance containing OH radicals generated by applying a high voltage to moisture in the air, the sterilization effect can be easily understood. Also, a line segment along the flow direction is used to display the airflow, and the length of the line segment is such that the airflow closer to the viewpoint is displayed longer and the airflow farther from the viewpoint is displayed shorter, so the state of the airflow can be visualized. Further, since the line segment is moved and displayed according to the flow velocity of the airflow, the state of the airflow can be visualized.

[0083] Also, the operation unit 330 is superimposed and displayed on a synthetic image in which the image of the real space 410 and the thermal fluid analysis result 160 are superimposed as AR. Since the operation unit 330 is arranged at a position where it can be operated by the thumb or any finger when held by both hands or one hand of the user, the operability of the user for displaying the thermal fluid analysis result 160 can be improved. Also, since the operation unit 330 to be superimposed on the synthetic image is arranged at either the left lower end portion 500 or the right lower end portion 502 of the display unit 340, the operability of the user can be improved. Also, since a switching button is arranged at the left lower end portion 500 of the display unit 340 and an operation control button is arranged at the right lower end portion 502 of the display unit 340, the operability of the user can be improved. Also, since a switching button is arranged at the right lower end portion 502 of the display unit 340 and an operation control button is arranged at the left lower end portion 500 of the display unit 340, the operability of the user can be improved.

[0084] Also, by detecting the presence or absence of finger contact with the display unit 340 within a predetermined time and switching the display and non-display of the operation control button, and constantly displaying the indicator 530, it is possible to achieve both an enlargement of the display area of the synthetic image and an improvement in the visibility of the notification. Also, since the indicator 530 is displayed at at least one of the upper right end or the upper left end of the display unit 340, the indicator 530 can be displayed at a position different from the operation unit 330.

[0085] In addition, since the operation control button has an operation button for operating at least one of switching the presence or absence of stopping the dynamic display and resetting the elapsed time since starting the addition of the diffusion substance to the air flow, the operability of the user can be improved. Further, since the switching button has an operation button for operating at least one of switching the presence or absence of adding the diffusion substance to the air flow and switching the addition amount of the diffusion substance to the air flow, the operability of the user can be improved. Further, the position where the operation unit 330 is superimposed on the composite image is switched and displayed so as to be in the same position with respect to the user's thumb by detecting the gripping portion where the housing 302 is gripped by hand, so that the operability of the user can be improved.

[0086] <Second Embodiment> The second embodiment of the present disclosure will be described centering on the differences from the first embodiment which is a premise example. Among the components of the second embodiment, the same or equivalent components as those in the first embodiment are denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0087] FIG. 17 is an overall configuration diagram of the visualization system according to the second embodiment. In the visualization system 1000 of the second embodiment, a plurality of display areas are provided in the display unit 340 of the portable information terminal 300, and a plurality of thermal fluid analysis results (for example, air flow analysis results) are AR-displayed in parallel in those plurality of display areas. Thereby, the variation points between the plurality of thermal fluid analysis results can be presented to the user in an easy-to-understand manner. The AR display of the thermal fluid analysis result in each display area can apply the AR display in the first embodiment. In the second embodiment, two thermal fluid analysis results (first thermal fluid analysis result and second thermal fluid analysis result) are AR-displayed in parallel, but of course, three or more thermal fluid analysis results may be AR-displayed in parallel.

[0088] The input terminal 100 inputs, in response to the operation of the user, first analysis target data (including analysis conditions) and second analysis target data (including analysis conditions) different from the first analysis target data into the analysis unit 130. The analysis unit 130 executes a first thermal fluid analysis based on the first analysis target data input from the input terminal 100, and executes a second thermal fluid analysis based on the second analysis target data input from the input terminal 100. The analysis unit 130 outputs the first thermal fluid analysis result and the second thermal fluid analysis result to the conversion unit 150.

[0089] The first thermal fluid analysis and the second thermal fluid analysis in the second embodiment are thermal fluid analyses performed under different conditions with the space imaged by the imaging unit 350 as the analysis space 10, and the first thermal fluid analysis result and the second thermal fluid analysis result are the results of thermal fluid analyses performed under different conditions. The analysis conditions may include information on the equipment arranged in the analysis space 10 (for example, model, size, operating conditions). Further, the analysis conditions may include information on the operating mode of the equipment described in relation to FIG. 5(b), and may include, for example, equipment, wind direction, air volume, concentration (concentration of diffusing substance), etc.

[0090] The first thermal fluid analysis result in the second embodiment includes the result of simulating the airflow flowing out from the air outlet installed on the analysis space 10 into the analysis space 10 and the diffusing substance of the first concentration contained in the airflow and diffused in the analysis space 10. Further, the second thermal fluid analysis result includes the result of simulating the airflow flowing out from the air outlet installed on the analysis space 10 into the analysis space 10 and the diffusing substance of the second concentration contained in the airflow and diffused in the analysis space 10. Typically, the first concentration and the second concentration are different concentrations.

[0091] The conversion unit 150 converts the first thermal fluid analysis result into the first AR data. Although the data formats of the first AR data and the first thermal fluid analysis result are different, since the first AR data also shows the first thermal fluid analysis result, hereinafter, the first AR data will also be referred to as the first thermal fluid analysis result. Also, the conversion unit 150 converts the second thermal fluid analysis result into the second AR data. Although the data formats of the second AR data and the second thermal fluid analysis result are different, since the second AR data also shows the second thermal fluid analysis result, hereinafter, the second AR data will also be referred to as the second thermal fluid analysis result. The conversion unit 150 outputs the first thermal fluid analysis result (the first AR data) and the second thermal fluid analysis result (the second AR data) to the server 200.

[0092] The server 200 stores a plurality of thermal fluid analysis results (AR data) to be displayed in parallel input from the conversion unit 150. In the second embodiment, the server 200 stores the first thermal fluid analysis result (the first AR data) and the second thermal fluid analysis result (the second AR data). The server 200 transmits the first thermal fluid analysis result (the first AR data) and the second thermal fluid analysis result (the second AR data) to the portable information terminal 300 in response to a request from the portable information terminal 300.

[0093] The display unit 340 of the portable information terminal 300 has at least a first display area and a second display area. The display unit 340 superimposes, as AR, an image of the space photographed by the imaging unit 350 and the first thermal fluid analysis result (the first AR data) with the space set as the analysis space 10 and displays it in the first display area. When displaying the first thermal fluid analysis result, the display unit 340 dynamically displays the state in which the first thermal fluid analysis result changes over time.

[0094] In parallel with the display of the first thermal fluid analysis result, the display unit 340 superimposes, as AR, an image of the space photographed by the imaging unit 350 and the second thermal fluid analysis result (the second AR data) with the space set as the analysis space 10 and displays it in the second display area. When displaying the second thermal fluid analysis result, the display unit 340 dynamically displays the state in which the second thermal fluid analysis result changes over time.

[0095] The control unit 320 of the mobile information terminal 300 further includes a density difference detection unit 322 and a synchronous display control unit 324. The synchronous display control unit 324 controls the display of a plurality of thermal fluid analysis results (AR data) in a plurality of display areas of the display unit 340. The fact that the display unit 340 displays the thermal fluid analysis results can also be said that the control unit 320 (synchronous display control unit 324) causes the display unit 340 to display the thermal fluid analysis results. The density difference detection unit 322 will be described later.

[0096] FIG. 18 shows a screen displayed on the display unit 340 of the mobile information terminal 300. FIG. 18 corresponds to FIG. 11(b) and shows the screen of the display unit 340 when the AR application is being executed on the mobile information terminal 300. In the second embodiment, the display unit 340 further displays a plurality of screen display switching buttons 515 superimposed on the composite image. The plurality of screen display switching buttons 515 are button objects for turning on and off the display of a plurality of thermal fluid analysis results in a plurality of display areas.

[0097] The synchronous display control unit 324 of the mobile information terminal 300 detects contact of a finger with the plurality of screen display switching buttons 515 displayed on the display unit 340, and switches between displaying and not displaying a plurality of thermal fluid analysis results in a plurality of display areas. The non-display of a plurality of thermal fluid analysis results includes causing the display unit 340 to display a single thermal fluid analysis result. By inputting a predetermined operation including pressing the plurality of screen display switching buttons 515, the user causes a plurality of thermal fluid analysis results to be displayed in a plurality of display areas on the display unit 340, and also switches the display mode of the plurality of thermal fluid analysis results.

[0098] FIG. 19 shows a screen displayed on the display unit 340 of the mobile information terminal 300. In response to the operation of the user, the synchronous display control unit 324 displays the first display area 600a and the second display area 600b side by side horizontally when the user holds the gripping portions on the left and right sides of the mobile information terminal 300 with both hands or one hand. In other words, the synchronous display control unit 324 displays the first display area 600a and the second display area 600b side by side in the horizontal direction.

[0099] In the example of FIG. 19, the synchronous display control unit 324 causes a part of the image captured by the imaging unit 350 of the real space (hereinafter also referred to as the "real space image 610") to be displayed in the first display area 600a, and causes another part of the real space image 610 to be displayed in the second display area 600b. In other words, each area obtained by dividing the real space image 610 into two parts is displayed in the first display area 600a and the second display area 600b, respectively. Further, when the first display area 600a and the second display area 600b are collectively referred to as the "display area 600", the synchronous display control unit 324 causes the real space image 610 to be displayed on the entire surface of the display area 600. In the example of FIG. 19, the monitor device installed in the space of the imaging target mainly appears in the real space image 610 of the first display area 600a, and the implant installed in the same space mainly appears in the real space image 610 of the second display area 600b.

[0100] FIG. 20 also shows a screen displayed on the display unit 340 of the portable information terminal 300. In the example of FIG. 20, the synchronous display control unit 324 causes the same real space image 610 to be displayed in both the first display area 600a and the second display area 600b, in other words, causes the same content to be displayed. In the example of FIG. 20, the monitor device installed in the space of the imaging target mainly appears in both the real space image 610 of the first display area 600a and the real space image 610 of the second display area 600b. The synchronous display control unit 324 switches between the display mode of the real space image 610 shown in FIG. 19 and the display mode of the real space image 610 shown in FIG. 20 according to the operation of the user.

[0101] In both examples of FIGS. 19 and 20, the synchronous display control unit 324 causes the first thermal fluid analysis result 612a (first AR data) to be displayed superimposed on the real space image 610 of the first display area 600a. In parallel with this, the synchronous display control unit 324 causes the second thermal fluid analysis result 612b (second AR data) to be displayed superimposed on the real space image 610 of the second display area 600b. Note that, as in the first embodiment, also in the second embodiment, the real space and the analysis space 10 are aligned by associating the real space marker 420 with the marker 20 in the analysis space 10.

[0102] Similar to the first embodiment, when the synchronous display control unit 324 overlays and displays the real-space image 610 and the first thermal fluid analysis result 612a in the first display area 600a, it colors the diffusing substance in the analysis space 10 on the projected real-space image 610 with a predetermined color, and expresses it by changing the transparency of the color colored according to the concentration of the diffusing substance. Also, when the synchronous display control unit 324 overlays and displays the real-space image 610 and the second thermal fluid analysis result 612b in the second display area 600b, it colors the diffusing substance in the analysis space 10 on the projected real-space image 610 with a predetermined color, and expresses it by changing the transparency of the color colored according to the concentration of the diffusing substance.

[0103] Next, a configuration for synchronously displaying the time of the first thermal fluid analysis result 612a (first AR data) and the second thermal fluid analysis result 612b (second AR data) will be described. Both the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b have time-series data starting from the point in time when the outflow of the air current into the analysis space 10 started from the air outlet installed in the analysis space 10. In other words, both the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b have data along the time axis starting from the point in time when the outflow of the air current into the analysis space 10 started. Specifically, both the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b have the wind direction, air volume, and concentration (diffusing substance concentration) at each position in the analysis space 10 for each elapsed time from the point in time when the outflow of the air current into the analysis space 10 started.

[0104] Figs. 21(a)-(c) show the screens displayed on the display unit 340 of the portable information terminal 300. In Figs. 21(a)-(c), the same real-space image 610 is displayed in the first display area 600a and the second display area 600b. The synchronous display control unit 324 synchronizes the time (in other words, the time axis) of the state in which the first thermal fluid analysis result 612a displayed in the first display area 600a changes in time series and the state in which the second thermal fluid analysis result 612b displayed in the second display area 600b changes in time series, and displays them. In other words, the synchronous display control unit 324 synchronizes the elapsed time from the point in time when the air current outflow started, and displays the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b in parallel.

[0105] Specifically, the synchronous display control unit 324 refers to the time (elapsed time from the start point of air flow outflow) associated with the data of the second thermal fluid analysis result 612b to be displayed in the second display area 600b, and causes the data of the first thermal fluid analysis result 612a associated with the same elapsed time to be displayed in the first display area 600a. In FIGS. 21(a)-(c), the time-series changes of the first thermal fluid analysis result 612a and the time-series changes of the second thermal fluid analysis result 612b are displayed with the time synchronized over the elapsed times t0, t1, t2 (where t0 < t1 < t2) from the start point of air flow outflow.

[0106] FIGS. 22(a)-(c) also show the screen displayed on the display unit 340 of the portable information terminal 300. In FIGS. 22(a)-(c), a part of the real-space image 610 is displayed in the first display area 600a, and another part of the real-space image 610 is displayed in the second display area 600b. Similar to FIGS. 21(a)-(c), in FIGS. 22(a)-(c) as well, the time-series changes of the first thermal fluid analysis result 612a and the time-series changes of the second thermal fluid analysis result 612b are displayed with the time synchronized over the elapsed times t0, t1, t2 from the start point of air flow outflow.

[0107] Next, the configuration of the highlighting display according to the difference between the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b will be described. FIGS. 23(a)-(b) show the screen displayed on the display unit 340 of the portable information terminal 300. The concentration difference detection unit 322 compares the concentration of the diffused substance (e.g., hypochlorous acid) associated with a certain elapsed time indicated by the first thermal fluid analysis result 612a with the concentration of the diffused substance associated with the same elapsed time indicated by the second thermal fluid analysis result 612b for each position in the analysis space 10 (it may also be for each grid having a certain range). The concentration difference detection unit 322 detects the difference between the concentration of the diffused substance indicated by the first thermal fluid analysis result 612a and the concentration of the diffused substance indicated by the second thermal fluid analysis result 612b for each position in the analysis space 10.

[0108] The concentration difference detection unit 322 detects, as a specific region 620, a region where the difference between the concentration of the diffusing substance indicated by the first thermal fluid analysis result 612a and the concentration of the diffusing substance indicated by the second thermal fluid analysis result 612b is equal to or greater than a predetermined value (which can also be said to be a set of positions where the concentration difference is equal to or greater than the predetermined value). The threshold value of the concentration difference for detecting the specific region 620 may be determined based on the developer's knowledge and experiments using the visualization system 1000. For example, the threshold value of the concentration difference in the case of di(hypochlorous acid) may be 4 ppb to 10 ppb.

[0109] The synchronous display control unit 324 causes the specific region 620 detected by the concentration difference detection unit 322 to be displayed in an emphasized manner. For example, the synchronous display control unit 324 may cause the specific region 620 to be displayed in a more prominent manner than the regions other than the specific region 620. Note that as time elapses from the start time of the airflow outflow, the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b change, and the position and shape of the specific region 620 also change.

[0110] In the second embodiment, the synchronous display control unit 324 identifies, as the specific region 620, the region with the relatively higher concentration among the regions of the first thermal fluid analysis result 612a and the region of the second thermal fluid analysis result 612b that have a concentration difference equal to or greater than a predetermined threshold value. As shown in FIG. 23(a), the synchronous display control unit 324 may highlight the specific region 620 by surrounding the specific region 620 with a line, in other words, by connecting the outer edges of the specific region 620 with a line. Further, as shown in FIG. 23(b), the synchronous display control unit 324 may highlight the specific region 620 by coloring the specific region 620 with a color different from that of the outside of the specific region 620 (typically a more prominent color).

[0111] FIG. 24 shows a screen displayed on the display unit 340 of the portable information terminal 300. The synchronous display control unit 324 causes the first display region 600a and the second display region 600b to be displayed vertically side by side in a state where the user holds the gripping portions on the left and right sides of the portable information terminal 300 with both hands or one hand in response to the user's operation. In other words, the synchronous display control unit 324 causes the first display region 600a and the second display region 600b to be displayed side by side in the vertical direction (perpendicular direction) in response to the user's operation.

[0112] According to the visualization system 1000 of the second embodiment, while displaying the changes in the time series of the first thermal fluid analysis result 612a superimposed on the real space image 610, the changes in the time series of the second thermal fluid analysis result 612b are also displayed superimposed on the real space image 610. Thereby, the difference points between the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b can be presented to the user in an easily understandable manner.

[0113] Also, according to the visualization system 1000 of the second embodiment, the difference points of a plurality of airflow analysis results carried out under different conditions can be presented to the user in an easily understandable manner. For example, the difference points between the diffusion situation simulation result of the diffusion substance of the first concentration shown by the first thermal fluid analysis result 612a and the diffusion situation simulation result of the diffusion substance of the second concentration shown by the second thermal fluid analysis result 612b can be presented to the user in an easily understandable manner.

[0114] Furthermore, according to the visualization system 1000 of the second embodiment, when generating the composite image of the real space image 610 and the first thermal fluid analysis result 612a, and when generating the composite image of the real space image 610 and the second thermal fluid analysis result 612b, the diffusion substance is colored in a predetermined color on the projected real space image 610, and the transparency of the color colored according to the concentration of the diffusion substance is changed. Thereby, the spatial concentration distribution of the diffusion substance as the first thermal fluid analysis result 612a and the spatial concentration distribution of the diffusion substance as the second thermal fluid analysis result 612b can be visualized, and the difference points between the two can be presented to the user in an easily understandable manner.

[0115] Furthermore, according to the visualization system 1000 of the second embodiment, since the region where the difference between the concentration of the diffusion substance shown by the first thermal fluid analysis result 612a and the concentration of the diffusion substance shown by the second thermal fluid analysis result 612b is equal to or greater than a predetermined value is highlighted, the region where the diffusion substance concentration differs significantly between the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b can be presented to the user in an easily understandable manner.

[0116] Furthermore, according to the visualization system 1000 of the second embodiment, in response to a user operation, the same image capturing the same real space can be displayed in the background of the thermal fluid analysis results in both the first display area 600a and the second display area 600b. Therefore, the differences between the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b can be presented to the user in an easily understandable manner. Furthermore, according to the visualization system 1000 of the second embodiment, in response to a user operation, a part of the real space image 610 can be displayed in the first display area 600a, and another part of the real space image 610 can be displayed in the second display area 600b. Therefore, a composite image adapted to the real space can be presented to the user.

[0117] Furthermore, according to the visualization system 1000 of the second embodiment, in response to a user operation, the first display area 600a (the first thermal fluid analysis result 612a) and the second display area 600b (the second thermal fluid analysis result 612b) can be arranged side by side horizontally, and can also be arranged one above the other vertically. Thereby, the user can compare the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b in a desired display mode.

[0118] Furthermore, according to the visualization system 1000 of the second embodiment, the state in which the first thermal fluid analysis result 612a changes in time series and the state in which the second thermal fluid analysis result 612b changes in time series can be displayed with time synchronized. Thereby, the differences between the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b on the same time axis can be presented to the user in an easily understandable manner.

[0119] The present disclosure has been described based on the first embodiment and the second embodiment. It is understood by those skilled in the art that the embodiments are illustrative, and various modifications are possible for each component or combination of each processing process of the embodiments, and such modifications are also within the scope of the present disclosure.

[0120] A first modification regarding the second embodiment will be described. The synchronization display control unit 324 may, in response to a user operation, arrange and display a plurality of display areas vertically and horizontally in a state where the user holds the gripping portions on the left and right sides of the portable information terminal 300 with both hands or one hand.

[0121] Figures 25 and 26 show the screens displayed on the display unit 340 of the portable information terminal 300. In Figures 25 and 26, four display areas (first display area 600a, second display area 600b, third display area 600c, fourth display area 600d) are arranged side by side vertically and horizontally. In the example of Figure 25, the synchronous display control unit 324 displays the same real-space image 610 in any of the first display area 600a, second display area 600b, third display area 600c, and fourth display area 600d. In the example of Figure 26, the synchronous display control unit 324 displays each area obtained by dividing the real-space image 610 into four in each of the first display area 600a, second display area 600b, third display area 600c, and fourth display area 600d.

[0122] In either example of Figure 25 or Figure 26, the synchronous display control unit 324 causes the first thermal-fluid analysis result 612a to be displayed in the first display area 600a, the second thermal-fluid analysis result 612b to be displayed in the second display area 600b, the third thermal-fluid analysis result 612c to be displayed in the third display area 600c, and the fourth thermal-fluid analysis result 612d to be displayed in the fourth display area 600d. The first thermal-fluid analysis result 612a, the second thermal-fluid analysis result 612b, the third thermal-fluid analysis result 612c, and the fourth thermal-fluid analysis result 612d are, for example, the results of thermal-fluid analyses performed under different conditions with the real space imaged by the imaging unit 350 as the analysis space 10.

[0123] A second modification of the second embodiment will be described. Figures 27(a)-(d) show the screens displayed on the display unit 340 of the portable information terminal 300. The display modes of the plurality of thermal-fluid analysis results shown in the above-described second embodiment and the modifications are also applicable to a vertical screen. A vertical screen is a screen whose vertical direction is longer than the horizontal direction.

[0124] Figure 27(a) shows the first display area 600a and the second display area 600b arranged side by side horizontally on the vertical screen. In Figure 27(a), the same real-space image 610 is displayed in both the first display area 600a and the second display area 600b. Figures 27(b) and 27(c) show the first display area 600a and the second display area 600b arranged vertically on the vertical screen. In Figure 27(b), the same real-space image 610 is displayed in both the first display area 600a and the second display area 600b. In Figure 27(c), each region obtained by dividing the real-space image 610 into two is displayed in the first display area 600a and the second display area 600b respectively. Figure 27(d) shows the first display area 600a, the second display area 600b, the third display area 600c, and the fourth display area 600d arranged vertically and horizontally side by side.

[0125] A third modification example related to the second embodiment will be described. In the second embodiment, the first thermal fluid analysis result 612a displayed in the first display area 600a and the second thermal fluid analysis result 612b displayed in the second display area 600b are the results of thermal fluid analyses performed under different conditions. As a modification example, the first thermal fluid analysis result 612a displayed in the first display area 600a and the second thermal fluid analysis result 612b displayed in the second display area 600b may be the results of thermal fluid analyses performed under the same conditions, or may be data showing the same results. In this case, the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b displayed simultaneously may have different elapsed times from the start time of the airflow outflow.

[0126] In the visualization system 1000 of the second embodiment, a region where the difference between the concentration of the diffused substance indicated by the first thermal fluid analysis result 612a and the concentration of the diffused substance indicated by the second thermal fluid analysis result 612b is equal to or greater than a predetermined value is detected as a specific region 620, and the detected specific region 620 is highlighted. However, when the user further taps the highlighted specific region 620 with a fingertip, the concentration of the diffused substance at the position where the fingertip taps may be numerically displayed in the vicinity of the tapped position (a position not hidden by the user's fingertip). In this case, it is preferable to also numerically display the concentration of the diffused substance at the position to be compared with the tapped position (if the specific region 620 is the second display region 600b, the corresponding position in the first display region 600a). Thereby, the variation points on the same time axis between the first thermal fluid analysis result 612a and the second thermal fluid analysis result 612b can be presented to the user in an easily understandable manner. Note that when tapping with a fingertip to numerically display the concentration of the diffused substance, the displayed numerical value may be changed together with the elapsed time, or the elapsed time may be stopped simultaneously when tapping with a fingertip. Here, the control operation of numerically displaying the concentration of the diffused substance at the position where the fingertip taps in the vicinity of the tapped position may be applied when, like the visualization system 1000 of the first embodiment, an image of the real space 410 captured by the imaging unit 350 and a single thermal fluid analysis result 160 in which the space is set as the analysis space 10 are superimposed and displayed on the display unit 340 as AR.
