Then, from the property information providing server 3, the property information posting page including the property information as the search result is transmitted to the general consumer terminal 1 that transmitted the search request via the network NW. At this time, the terminal identification data transmitted together with the search request is used as a clue. Then, the system control unit 13 of the general consumer terminal 1 that has received the property information posting page displays the property information posting page on the display of the display operation unit 14 . The creation and display of the floor plan using the above-described floor plan creation/display page by the property information providing server 3 will be described in detail later.

The information providing server 3 is a server that constitutes a property information site. The information providing server 3 includes a communication section 31 , a storage section 32 , a system control section 33 and the like, and these components are electrically connected via a bus 34 . The information providing server 3 may be composed of one server computer, or may be composed of a plurality of server computers. Here, the communication section 31 is an example of the "acquisition means" in the present invention. The storage unit 32 is an example of "storage means" in the present invention.

Under the control of the system control unit 33, the communication unit 31 communicates with each general consumer terminal 1 via the network NW. The storage unit 32 is configured by, for example, a hard disk drive, etc., and stores an OS, applications, and the like. In the storage unit 32, a property information database (DB) 321, a reference data database (DB) 322 of the present embodiment, and the like are constructed. FIG. 2 is a diagram showing an example of information registered in the property information database 321, and FIG. 3 is a diagram showing an example of information registered in the reference data database 322. As shown in FIG. Note that the property information database 321 and the reference data database 322 may each be provided in another server different from the information providing server 3 .

As illustrated in FIG. 2, the property information database 321 registers (stores) property information on a property, the broker ID of the broker who provided the property information, and the property ID of the property in association with each other. A broker is a business that introduces or mediates real estate properties to the general consumers. The broker acquires property information indicating the details of the real estate property from the management company that owns/manages the real estate property itself, and introduces the real estate property to general consumers based on this information. This broker is a real estate agent that you often see in town. With such property information database 321, a large amount of property information can be managed separately for each broker. Here, the intermediary agent ID is identification information uniquely assigned to each intermediary agent. The property ID is identification information uniquely given to each broker and to each property. In other words, the same property may be handled by a plurality of different brokers, and even if the same property is handled by different brokers, the property ID will be different. The property information includes, for example, property type, property name, location, traffic, building age, number of floors, exclusive area, exterior image, floor plan information, transaction information, and the like (see FIG. 6). The property type is classified into individual housing (detached house), collective housing (condominium or apartment), and land. The floor plan information when the property type is an apartment complex includes the floor where each unit (each room) is located, the room number, the floor plan, and images of rooms, facilities, and the like. The transaction information includes, for example, transaction type and transaction conditions. Transaction types are classified into rental property, new property, and second-hand property. Transaction conditions for rental properties include rent, security deposit, key money, and contract period. Transaction conditions for new properties and second-hand properties include sales prices, management fees, reserve funds for repairs, and the like. Designation of property information by a broker is essential in principle.

The reference data database 322 registers (stores) reference data used for creating the floor plan of the present embodiment. The reference data of the present embodiment constitutes a floor plan showing a two-dimensional floor plan of a real estate property based on the trajectory of lines input by the freehand input operation on the display operation unit 14 of each general consumer terminal 1. This is the data used to generate the image of the structure that The two-dimensional floor plan in this case is, for example, a general two-dimensional floor plan FP showing the floor plan of a real estate property, as illustrated in FIG. 3(A). Further, the components constituting the floor plan FP are, for example, one room, one window, one door, one toilet, etc., which constitute the floor plan. The reference data of the present embodiment is based on how each of the plurality of types of components (the rooms, etc.) constituting the two-dimensional floor plan FP is drawn by the freehand input operation. , and shape criteria (ie, how to draw including the stroke order and typical examples of the shape). By comparing the trajectory of the line actually input by the freehand input operation on the display operation unit 14 with this reference data, the composition indicated by the reference data in the drawing style and shape that is closest to the trajectory. is determined. Then, the trajectory of the line actually input by the freehand input operation is converted into a drawing of the determined structure.

Here, the reference data of the present embodiment will be specifically described with reference to FIG. 3(B). In the "trajectory" column of FIG. 3B, "● (black circle)" indicates the starting point of the freehand input operation, and the tip of the arrow indicates the end point of the input operation. Specifically, as the reference data of the present embodiment, when a closed-shaped trajectory indicated by a solid line is input in the 'trajectory' column as exemplified as 'Room 1' in FIG. The trajectory is converted into a rectangular drawing having the width and depth of the entire trajectory as a drawing of one room constituting the floor plan FP. Also, as illustrated in FIG. 3(B) as "Room 2", in a state in which the wall as the component indicated by the dashed line is displayed in the "trajectory" column, a closed shape that is in contact with the dashed line is displayed. When a trajectory is entered as indicated by a solid line, the trajectory is converted to a rectangular drawing of a room with the width and depth of the entire trajectory (indicated by a dashed line) as a drawing of one room in contact with the walls of the room. rectangular drawing on the wall). Also, as illustrated as "window" in FIG. 3(B), in a state in which the wall illustrated by the dashed line is displayed in the "trajectory" column, a part of the wall is distinguished from other parts. When two trajectories are input as indicated by the solid lines, the portion of the wall that is sandwiched between the trajectories and distinguished by the trajectories is a sliding door-type window made in the wall. It is converted into a drawing of a sliding door type window that serves as the frontage. Also, as shown in FIG. 3B as an example of a "door", in a state in which the above-mentioned wall indicated by a broken line is displayed in the "trajectory" column, a part of the wall is set as a starting point and substantially perpendicular to the wall. If a trajectory is input as indicated by a solid line that once leaves in a direction and then draws a substantially circular shape and returns to the original wall, the trajectory will have the wall between the start and end points of the trajectory as the frontage. Converted to a drawing of a single door. Also, as illustrated in FIG. 3(B) as "Toilet", in a state where the above-mentioned wall illustrated by a dashed line is displayed in the "Locus" column, a part of the wall is used as a starting point and protrudes from the wall. If a trajectory that draws a substantially elliptical shape and returns to the original wall is input as indicated by the solid line, the trajectory is converted to a drawing of the toilet provided between the start point and the end point of the trajectory. . Also, as exemplified in FIG. 3(B) as "washroom", in a state where the above-mentioned wall exemplified by a broken line is displayed in the "trajectory" column, a substantially elliptical trajectory that touches the wall is entered as indicated by the solid line, the locus is transformed into a drawing of the washbasin with the width of the entire locus. In addition, as illustrated in FIG. 3B as "kitchen", in a state where the above-mentioned wall exemplified by a broken line is displayed in the "trajectory" column, a substantially elliptical trajectory is drawn so as to be in contact with the wall. , a substantially rectangular trajectory, and a linear trajectory connecting them are input as indicated by solid lines, these trajectories are converted into a drawing of a kitchen having the width of the entire trajectory. Also, as illustrated in FIG. 3(B) as "bathroom", when substantially elliptical trajectories are input in the "trajectory" column so as to be doubled as indicated by solid lines, those trajectories are , is transformed into a drawing of the bathtub with the width and depth of its entire trajectory (outer trajectory). Finally, as illustrated as a "bay window" in FIG. Furthermore, when a single trajectory returning to another part of the wall is input as indicated by the solid line, that trajectory is the bay window whose frontage is the length of the part of the wall that is sandwiched by the trajectory. converted to drawings. Note that the floor plan FP of a house, condominium, etc. as a real estate property includes drawings of various components other than the components illustrated in FIG. A reference data database 322 is registered with reference data that can be distinguished from other components by the trajectory they represent.

The property list display area R2 is an area for displaying a list of properties searched according to designated search conditions. In the property list display region R2, a property display region R2a, a property display region R2b, a property display region R2c, . When the general consumer terminal 1 receives the property information listing page, as shown in FIG. 6, the property display region R2a, the property display region R2b, and the property display region R2c whose display order is set higher are displayed on the screen. be done. Then, by scrolling the property information page by the scrolling operation of the general consumer, the property display region R2d and the subsequent property display regions R2c whose display order is set lower than the property display region R2c are displayed on the screen. In each property display area, part of the property information in the property information (e.g., property name, property type, rent, location, transportation, exclusive area, floor plan, etc.), link characters and buttons to detailed pages, etc. displayed (inquiry button may be displayed). For example, the property name 101 and "see details" 102 displayed in the property display area R2a are characters that link to a detailed page, and when this link is clicked or tapped, the detailed page is provided by the page providing unit 331. will be Although not shown, the detail page displays almost all of the property information in the property information, broker information, and an inquiry button (in some cases, a material request button is also displayed). Furthermore, although not shown, the detail page displays a panoramic image, staff comments, etc. as an advertisement for the property. The advertisement display area R3 is an area for displaying an advertisement of a property (for example, a banner advertisement with a link to a detail page) according to selection. Such an advertisement display area R3 may also be provided on a page (for example, a blog page, etc.) provided by a specific site (not limited to a property information site) other than the property information posting page.

Next, the search unit 332 of the system control unit 33 retrieves the trajectory data included in the floor plan image data request transmitted from the general consumer terminal 1 using the floor plan creation/display page (see FIG. 5). etc., the reference data database 322 is searched, and the reference data (see FIG. 3) of the structure corresponding to the trajectory data or the like is specified. More specifically, for example, when trajectory data or the like indicating the trajectory indicated as "room 1" in FIG. 322 to identify the reference data of the "room 1". As a result, the floor plan image data generation unit 333 reads out the specified reference data from the reference data database 322 based on the reference data specifying information from the search unit 332, and creates a floor plan corresponding to the reference data. Generate floor plan image data. For example, when reading the reference data indicated as "Room 1" in FIG. Floor plan image data corresponding to a rectangular drawing having an overall width and depth is generated. Note that when the locus data and the like corresponding to the operation of the correction button 201 are newly transmitted from the general consumer terminal 1, the search unit 332 performs the reference based on the locus data and the like newly transmitted. The data database 322 is searched to identify the corresponding reference data, and the floor plan image data generation unit 333 reads the identified reference data from the reference data database 322 and generates a floor plan image corresponding to the corresponding floor plan. Generate new data.

Here, based on the request corresponding to the operation of the three-dimensional button 202 from the general consumer terminal 1, the floor plan image data generation unit 333 corresponds to the two-dimensional floor plan image data corresponding to the reference data (that is, the relevant 3D floor plan image data representing a 3D model is generated by converting a 2D floor plan image into 3D. The generation of the three-dimensional floor plan image data will be described in detail later with reference to FIGS. 7 and 8. FIG. After that, the display control unit 334 transmits the floor plan image data generated by the floor plan image data generation unit 333 to the general consumer terminal 1 that has transmitted the floor plan image data request based on the terminal identification data. As a result, the general consumer terminal 1 to which the floor plan image data has been transmitted displays the floor plan image corresponding to the floor plan image data (that is, the two-dimensional floor plan image or the three-dimensional floor plan image) on the floor plan creation/display page. It is displayed using the image display area R20. When a search request corresponding to the operation of the property search button 203 is transmitted from the general consumer terminal 1 on which the floor plan image is displayed, the property information acquisition unit 335 acquires the search conditions included in the search request. The property information database 321 is searched using, and property information corresponding to the search result is output to the page providing unit 331 . As a result, the page providing unit 331 transmits the property information providing page (see FIG. 6) including the output property information to the general consumer terminal 1 that has transmitted the search request based on the terminal identification data. do. Then, the general consumer terminal 1 to which the property information providing page is transmitted displays it on the display of the display operation section 14 .

Next, generation of three-dimensional floor plan image data by the floor plan image data generation unit 333 will be specifically described with reference to FIGS. 7 and 8. FIG. 7 and 8 are diagrams illustrating the process of creating three-dimensional floor plan image data according to the present embodiment.

The floor plan image data generation unit 333 first generates two-dimensional floor plan image data based on the locus data and the like transmitted from the general consumer terminal 1 and the reference data, and sends it to the general consumer terminal 1. Send and display the corresponding two-dimensional floor plan image. Here, it is assumed that the floor plan of the displayed two-dimensional floor plan image is the floor plan FP shown in FIG. 7A, for example. The floor plan FP illustrated in FIG. 7A is a floor plan of the lower left room RM1 (that is, the left room facing the veranda) in the floor plan FP illustrated in FIG. 3A. In the floor plan FP shown in FIG. 7A, one room RM1 is composed of walls W1 to W4, wall W1 has a sliding door SD1, wall W2 has a sliding door SD2, and wall 3 has a sliding door SD2. There is a window WD. When the three-dimensional request is transmitted from the general consumer terminal 1 displaying the floor plan image of the floor plan FP illustrated in FIG. A three-dimensional model is generated by converting the drawing image into three dimensions, and based on this, three-dimensional floor plan image data corresponding to the three-dimensional floor plan image illustrated in FIG. 7B is generated. More specifically, based on the positions and lengths of walls W1 to W4 shown in FIG. By determining the ceiling height from the floor surface and generating a three-dimensional model having the ceiling height, that is, a three-dimensional model consisting of the floor surface, the ceiling surface, and the wall surface, the three-dimensional model illustrated in FIG. Three-dimensional floor plan image data corresponding to the floor plan image is generated. In addition, the floor plan image data generation unit 333 determines that the horizontal positions and frontages of the three-dimensional floor plan image of the sliding door SD1, the sliding door SD2, and the window WD correspond to the floor plan FP illustrated in FIG. 7A. We assume position and frontage that we did. Furthermore, the floor plan image data generation unit 333 generates the vertical positions and heights of the sliding door SD1, the sliding door SD2, and the window WD in the three-dimensional floor plan image according to the standard for each of the sliding door SD1, the sliding door SD2, and the window WD. position and height. After that, the display control unit 334 transmits the three-dimensional floor plan image data generated by the floor plan image data generation unit 333 to the general consumer terminal 1 that has transmitted the three-dimensional conversion request, based on the terminal identification data. The image is transmitted via the network NW, and the corresponding three-dimensional floor plan image (see FIG. 7(B)) is displayed.

Then, in response to the operation of the correction button 201, the trajectory of correction to the effect that, for example, the window WD is a window from the floor from the three-dimensional floor plan corresponding to the three-dimensional floor plan image illustrated in FIG. 7B. When the data and the like are transmitted, the floor plan image data generation unit 333 corrects the window WD in the three-dimensional floor plan image illustrated in FIG. Floor-plan image data corresponding to a three-dimensional floor-plan image of the room RM1' having the window WDD is generated. Thereafter, the display control unit 334 transmits the corrected floor plan image data via the network NW to the general consumer terminal 1 that has transmitted the corrected trajectory data and the like, and corresponds to the corrected floor plan image data. A three-dimensional floor plan image (see FIG. 7C) is displayed.

On the other hand, in response to the operation of the correction button 201, the trajectory data for correction such as widening the width of the window WD, for example, is generated from the three-dimensional floor plan corresponding to the three-dimensional floor plan image illustrated in FIG. When it is transmitted, the floor plan image data generation unit 333 generates the window WD in the three-dimensional floor plan image illustrated in FIG. 8A (the floor plan image is the same as the floor plan image illustrated in FIG. 7B). Correction is performed to widen the width to the width indicated by the locus data or the like, and floor plan image data corresponding to the three-dimensional floor plan image of the room RM1″ illustrated in FIG. 8B is generated. After that, the display control unit 334 , the corrected floor plan image data is transmitted via the network NW to the general consumer terminal 1 that has transmitted the corrected trajectory data, etc., and a three-dimensional floor plan image corresponding to the corrected floor plan image data ( In addition, the floor plan image data generation unit 333 displays the two-dimensional floor plan FP (see FIG. 3A or FIG. 7A) of the original room RM1. The window WD is also corrected to widen its width like the window WDW of the floor plan FP illustrated in FIG. 8(C).

[2. Operation of information providing system S]
Next, the operation of the information providing system S of this embodiment will be described with reference to FIG. FIG. 9 is a sequence diagram showing an operation example of the information providing system of this embodiment.

As shown in FIG. 9, in providing the floor plan image data and the property information in this embodiment, for example, after accessing the property information site according to the user's operation on the general consumer terminal 1 and completing the login, the floor plan A request to transmit a creation/display page is transmitted from the general consumer terminal 1 to the information providing server 3 via the network NW (step S1). In response to the request, the page providing unit 331 of the information providing server 3 provides the floor plan creation/display page illustrated in FIG. 5 to the general consumer terminal 1 via the network NW (step S2). Next, the system control unit 13 of the general consumer terminal 1 to which the floor plan creation/display page has been transmitted displays the received floor plan creation/display page on the display of the display operation unit 14 (step S3).

Next, using the trajectory input area 100 of the displayed floor plan creation/display page, lines indicating the components that make up the real estate property for which the floor plan is desired to be created are input freehand for one component. Then (step S4), the trajectory data corresponding to the trajectory of the line and the like are sent to the information providing server 3 together with the terminal identification data of the general consumer terminal 1 via the network NW (step S5). Next, the search unit 332 of the information providing server 3 searches the reference data database 322 based on the received trajectory data and the like to identify the corresponding reference data (step S6). Next, the floor plan image data generator 333 reads out the specified reference data from the reference data database 322 and generates two-dimensional floor plan image data corresponding to the corresponding floor plan (step S7). Next, the display control unit 334 sends the generated two-dimensional floor plan image data to the general consumer terminal 1 identified by the terminal identification data based on the terminal identification data transmitted together with the trajectory data and the like in step S5. Send (step S8). Next, the system control unit 13 of the general consumer terminal 1, to which the two-dimensional floor plan image data has been transmitted, generates a two-dimensional floor plan FP for one component corresponding to the received two-dimensional floor plan image data. (See FIG. 3A or FIG. 7A) is displayed in the display area 200 of the floor plan creation/display page displayed on the display of the display operation unit 14 (step S9). Next, the system control unit 13 monitors whether or not the correction button 201 on the floor plan creation/display page has been operated, for example, for a preset period of time (step S10). If the correction button 201 is operated in the determination of step S10 (step S10: YES), the system control unit 13 returns to step S4 to correct the two-dimensional floor plan displayed in the display area 200. , waits for the input of the correction line or the like. When a correction line or the like is input, the above step S4 and subsequent steps are repeated for the trajectory data of the trajectory corresponding to the correction line or the like.

On the other hand, if the correction button 201 has not been operated in step S10 (step S10: NO), then the system control unit 13 determines whether or not the three-dimensional conversion button 202 of the floor plan creation/display page has been operated. For example, monitoring is performed only for a preset time (step S11). If the three-dimensionalization button 202 is not operated in step S11 (step S11: NO), the system control unit 13 proceeds to step S16, which will be described later. On the other hand, when the three-dimensional conversion button 202 is operated in the determination in step S11 (step S11: YES), the system control unit 13 converts the two-dimensional floor plan FP displayed in the display area 200 into three dimensions. The three-dimensional rendering request is transmitted to the information providing server 3 together with the terminal identification data via the network NW (step S12). Next, the floor plan image data generating unit 333 of the information providing server 3 that has received the three-dimensional rendering request generates the image based on the floor plan image data of the two-dimensional floor plan FP displayed in the display area 200 using, for example, FIG. By the method described above, three-dimensional floor plan image data corresponding to a three-dimensional model obtained by transforming the two-dimensional floor plan image into three dimensions is generated (step S13). Next, the display control unit 334 converts the generated three-dimensional floor plan image data to the general consumer terminal 1 identified by the terminal identification data based on the terminal identification data transmitted together with the three-dimensional conversion request in step S12. (step S14). Next, the system control unit 13 of the general consumer terminal 1 to which the three-dimensional floor plan image data has been transmitted receives the three-dimensional floor plan image corresponding to the received three-dimensional floor plan image data (FIG. 7B or 8A) is displayed in the display area 200 of the floor plan creation/display page (step S15). Next, the system control unit 13 monitors whether or not the property search button 203 on the floor plan creation/display page has been operated, for example, for a preset period of time (step S16). If the property search button 203 is not operated in the determination of step S16 (step S16: NO), the system control unit 13 returns to step S4 to generate a two-dimensional floor plan for the next structure. Waits for input such as a line indicating a new composition. When a new line or the like is input, the steps after step S4 are repeated for the trajectory data of the trajectory corresponding to the new line or the like.

On the other hand, in the determination of step S16, if the property search button 203 has been operated (step S16: YES), then the system control unit 13 sends the search request including the search conditions to the information providing server via the network NW. 3 (step S17). Next, the property information acquisition unit 335 of the information providing server 3 that has received the search request searches the property information database 321 using the search conditions included in the search request, and obtains property information corresponding to the search result. is output to the page providing unit 331 (step S18). Next, the page providing unit 331 transmits the property information providing page (see FIG. 6) including the output property information to the general consumer terminal 1 that has transmitted the search request, based on the terminal identification data. (Step S19). Next, the system control unit 13 of the general consumer terminal 1 to which the property information providing page has been transmitted displays the property information posting page on the display of the display operation unit 14 (step S20).

As described above, according to the information providing system S of the present embodiment, the trajectory data indicating the trajectory of the line of the structure input freehand is converted into two-dimensional floor plan image data based on the reference data.

In addition, since the reference data is the reference data indicating the reference of the shape and the way of drawing when the components of the floor plan are drawn freehand (see FIG. 3B), the two-dimensional floor plan image can be more accurately displayed. can be displayed.

Furthermore, the reference data is the reference data for each type of structure (see FIG. 3B), and based on the reference data for each type, the trajectory data and the like are converted into two-dimensional floor plan image data for each type. Therefore, it is possible to accurately and easily display a two-dimensional floor plan image for each type of component that constitutes the two-dimensional floor plan of the room.

Furthermore, when the stroke order data is included as locus data or the like, the locus data can be converted into more accurate two-dimensional floor plan image data.

Further, since the locus data is converted into the two-dimensional floor plan image data based on the detailed data indicating the input start timing of each line by freehand and the reference data, the locus data can be converted to a more accurate two-dimensional floor plan. It can be converted into image data.

In addition, based on the reference data, the trajectory data for correction, etc. is converted into two-dimensional floor plan image data of the room, and based on the two-dimensional floor plan data of the room, the room corresponding to the trajectory data for correction, etc. Since the two-dimensional floor plan image is corrected and displayed (see step S10 in FIG. 9: YES), the two-dimensional floor plan image of the room can be easily corrected according to the user's preference.

Furthermore, each time one locus data is obtained in parallel with the input of one line, the one locus data is converted into one two-dimensional floor plan image data, and the one locus data is converted into one two-dimensional floor plan image data. Each time it is converted into floor plan image data, a two-dimensional floor plan image of the room is displayed based on the one two-dimensional floor plan image data (see steps S1 to S9 in FIG. 9). In parallel with the input, a two-dimensional floor plan image of the room corresponding to the line can be displayed in real time.

Furthermore, three-dimensional model data is generated based on the two-dimensional floor plan image data, and a three-dimensional floor plan image of the room is displayed based on the three-dimensional model data (steps S13 and S15 in FIG. 9, 7(B) and 8(A)), it is possible to easily display a three-dimensional floor plan image of a room based on lines input by freehand.

Also, in the display of the three-dimensional floor plan image, each time one locus data is acquired, it is converted into one two-dimensional floor plan image data and corresponding one three-dimensional model data is generated, Each time the one piece of 3D model data is generated, a 3D floor plan image of the room is displayed (see FIGS. 7B and 8A). , a three-dimensional floor plan image of the room corresponding to the line can be displayed in real time.

Furthermore, since the types of constituents of the real estate property to which the reference data correspond are walls, windows, doors, etc., it is possible to easily display a floor plan image of a room constituted by such walls.

Furthermore, since the real estate property is searched based on the property information indicating the real estate property including the room whose floor plan is indicated (see steps S18 and S19 in FIG. 9 and FIG. 6), the real estate property that matches the user's preference can be searched. can be searched while imagining a specific floor plan.

In the information providing system S of the present embodiment described above, a two-dimensional or three-dimensional floor plan image is displayed in the image display area R20 of the floor plan creation/display page. Of the real estate properties including the floor plan (room) corresponding to the image, for example, property information indicating nearby real estate properties or popular real estate properties may be displayed together. In this case, the two-dimensional floor plan image is displayed together with the property information indicating the real estate property including the corresponding room, so that the state of the room can be recognized more specifically.

In addition to the operation of the information providing system S of the present embodiment described above, after displaying the three-dimensional floor plan image, the three-dimensional When the operation of the correction button 201 for correcting the floor plan image is accepted after step S15 in FIG. 9, for example (see FIGS. 7C, 8B, and 8C), the Then, the trajectory data for correcting the 3D floor plan image is converted into 3D floor plan image data of the room, and based on the 3D floor plan data of the room, the room corresponding to the 3D corrected trajectory data is calculated. By configuring the 3D floor plan image to be corrected and displayed, the 3D floor plan image of the room can be easily corrected according to the user's preference.

Furthermore, in the operation of the information providing system S of the present embodiment described above, after the two-dimensional floor plan image is once displayed (see step S9 in FIG. 9), the corresponding three-dimensional floor plan image is displayed (step S15 in FIG. 9). In addition to this configuration, the configuration may be such that the three-dimensional floor plan image is displayed from the beginning without displaying the two-dimensional floor plan image.
