When the potential customer selects the answer completion icon 64 on the questionnaire input screen 61, an overall map screen 71 of the VHP 22 is displayed as shown in FIG. The overall map screen 71 corresponds to the first display screen. Since the input of the questionnaire is optional, even if the potential customer selects the rejection icon 53 on the start screen 51 or selects the answer stop icon 65 on the questionnaire input screen 61, the entire map screen 71 of the VHP 22 is similarly displayed. Is displayed. An overview of the VHP 22 will be described below.

A plurality of houses 23 are provided in the VHP 22 . The VHP 22 has a plurality of exhibition zones that collect and exhibit houses according to their respective themes. 76” (hereinafter collectively referred to as “exhibition zones 74 to 76”). The Japanese-style zone 74 collects and exhibits Japanese-style houses such as houses with Japanese gardens. The urban zone 75 collects and exhibits residences such as three-story residences to be constructed in urban areas. The ecology zone 76 is a collection and display of eco-friendly houses equipped with facilities such as solar panels, hydrogen stations, and storage batteries. On the overall map screen 71, each of the exhibition zones 74-76 is displayed in an abstract manner to the extent that the themes of each of the exhibition zones 74-76 can be understood. Therefore, the detailed configuration within the exhibition zones 74 to 76 will be described later.

On the overall map screen 71, block screen display icons 77 are displayed above the respective exhibition zones 74-76. The block screen display icon 77 can be selected by the potential customer on the information terminal 13 and is associated with the exhibition zone under each block screen display icon 77 . When the potential customer selects one of the town block screen display icons 77, a screen displaying the contents of the exhibition zones 74 to 76 associated with the selected town block screen display icon (that is, a "town block screen 81" to be described later). is displayed on the information terminal 13 . That is, the overall map screen 71 has the function of displaying the overall image of the VHP 22 and displaying a list of a plurality of exhibition zones 74 to 76 so that the potential customer can select the exhibition zone 74 to 76 to visit. is doing.

A return icon 78 is displayed on the overall map screen 71 . The potential customer can return to the questionnaire input screen 61 by selecting the return icon 78 on the information terminal 13 .

As a result, potential customers can proceed to tour each of the exhibition zones 74-76 with a greater desire to purchase.

(Exhibition Zones 74-76)
Next, the construction of the exhibition zones 74 to 76 will be described with reference to FIG. 5, taking the urban zone 75 as an example. FIG. 5 is a diagram showing a block screen 81 as a second screen displayed on the information terminal 13 of the potential customer and displaying the contents of the urban zone 75. As shown in FIG. Although not shown, the other exhibition zones 74 and 76 also have their corresponding block screens. These town block maps correspond to the second display screen.

A three-dimensional image of the appearance of the house 23 and a three-dimensional image of the surrounding environment of the house 23 created by CG are displayed on the block screen 81 . As a result, the streetscape in the urban zone 75 is represented on the town block screen 81 . The stereoscopic image of the surrounding environment includes roads along which the potential customer travels. Since the urban zone 75 has the theme of "collecting and exhibiting houses such as three-story houses to be built in urban areas", other than the above roads, for example, a group of buildings can be used as a background. , or structures other than residences, such as convenience stores, are displayed to express the world view of the urban zone 75 .

Considering the original configuration of the VHP 22, it is natural that the part of the VHP 22 other than the urban zone 75 is reflected in the background of the city block screen 81. FIG. However, in the present embodiment, only the contents for expressing the world view of the urban zone 75 are displayed on the street block screen 81, and the parts of the VHP 22 other than the urban zone 75 are not displayed. It's becoming

On the town block screen 81, the potential customer is displayed as if he or she were in the actual townscape, such as Google (registered trademark) Street View (registered trademark). On the block screen 81, an arrow-shaped viewpoint movement icon 93 is displayed. When the potential customer selects the viewpoint movement icon 93 , the viewpoint moves in the arrow direction of the selected viewpoint movement icon 93 . That is, since the potential customer can move the position of the viewpoint by appropriately selecting the viewpoint movement icon 93, the potential customer can observe the appearance of the house 23 as if walking in the actual townscape. The following explanation is based on the premise that the potential customer is in the virtual reality space, assuming that the viewpoint being displayed on the block screen 81 or the like is the viewpoint of the potential customer.

A return icon 82 is displayed on the block screen 81 . The potential customer can return to the overall map screen 71 by selecting the return icon 82 on the information terminal 13 .

A display switching area 84 corresponding to each house 23 is displayed outside the entrance of each house 23 on the block screen 81 . The display switching area 84 is a circular area in a plan view, and a potential customer can enter by walking on the block screen 81 . Then, when the potential customer enters the display switching area 84 on the town block screen 81, the display format on the potential customer's information terminal 13 is changed to the exterior viewing display 85 ( See FIG. 6). In the exterior viewing display 85, the potential customer can operate the information terminal 13 to view stereoscopic images of the exterior of the house from all angles.

Then, when the display form is switched to the appearance viewing display 85, the display form first shows the appearance of the house from the front (see FIG. 6A). In the external view display 85, an internal view display icon 86 is displayed on the target house 23 for the external view display. When the potential customer selects the inside view display icon 86, a screen displaying the inside view of the house under the inside view display icon (that is, an "inside view screen 91" to be described later) is displayed on the information terminal 13. . In other words, the town block screen 81 has a function that enables a potential customer who has visited the exterior of a house 23 in the urban zone 75 to select a house that he/she wishes to see the interior from among the houses 23 in the urban zone 75. is doing.

In addition, in the appearance observation display 85, an arrow-shaped rotation icon 88 is displayed. When the potential customer selects the rotation icon 88 , the stereoscopic image is horizontally rotated in the direction of the arrow of the selected rotation icon 88 . The stereoscopic image of the house can be rotated in any direction by the potential customer performing an operation such as dragging on the screen of the information terminal 13 . Therefore, the potential customer can freely rotate the stereoscopic image by combining operations such as selection and dragging of the rotation icon 88 . As a result, potential customers can check not only how the house is viewed from the ground, but also how the roof of the house looks like, as shown in FIG. 6(b), for example.

A return icon 87 is displayed in the exterior viewing display 85 . When the potential customer selects the return icon 87 on the information terminal 13, the appearance viewing display state is canceled and the block screen 81 returns to the normal display form.

Next, the interior view screen 91, which is displayed on the information terminal 13 of the potential customer and serves as the third screen for displaying the interior view of the house 23, will be described with reference to FIG. Note that the interior view screen 91 corresponds to each house 23, and FIG. 7 is merely an example. The introspection screen 91 corresponds to the third display screen.

On the interior view screen 91, a stereoscopic image of the interior view of the house 23 is displayed. The three-dimensional image of the inside view of the house 23 is generated based on the photographed data of the actually constructed house 23 . An arrow-shaped viewpoint movement icon 93 is displayed on the introspection screen 91 as well as on the block screen 81 . Therefore, by appropriately selecting the viewpoint movement icon 93, the potential customer can walk through the house 23 in a 360-degree image, like Street View (registered trademark) of Google (registered trademark). As a result, the potential customer can observe the interior of each room while moving through the house 23 while enjoying the feeling of actually living in the house 23. - 特許庁

A return icon 92 is displayed on the introspection screen 91 . When the potential customer selects the return icon 92 on the information terminal 13, the display 85 for viewing the appearance of the house is displayed.

In addition, the VHP 22 can display a "recommendation screen 94" (see FIG. 8) that collectively displays houses that match the preferences of the potential customer, although the details will be described later. On the recommendation screen 94, a list 95 is displayed that summarizes the product name and recommended points of each house 23 for houses that match the preferences of the potential customer. When the potential customer selects the part of the product name of the house in the list 95, the introspection screen of the house is displayed. The recommendation screen 94 also displays a return icon 97 for returning to the block screen 81 and an exit icon 98 for exiting from the VHP 22 .

Then, as shown in FIG. 9, a recommendation display icon 99 is displayed on the block screen when a predetermined condition is satisfied. When the potential customer selects the recommendation display icon 99 on the information terminal 13, a recommendation screen 94 is displayed if a predetermined condition is satisfied. That is, the recommendation display icon 99 has a function of prompting the potential customer to display the recommendation screen 94, and corresponds to a guidance message.

(Housing information database DB1)
The VHP 22 is characterized in that a plurality of houses 23 are classified according to system by exhibition zones 74 to 76 and displayed. The classification of the plurality of houses 23 is performed based on the house information of each house registered in the house information database DB1. Therefore, registration in the housing information database DB1 in this embodiment will be described with reference to FIG.

The information input unit 33 allows the seller to operate the management terminal 14 to access the housing information database DB1 and input housing information.

House information is stored in the house information database DB1 for each house. The housing information can be roughly classified into "manufacturer name", "product name", "main category", "subcategory", "recommended point", and "video data".

First, a "maker name" and a "product name" are registered for each house.

Next, a "main category" is registered for each house. The main category is used to classify each house into exhibition zones. It is designed to be registered (tagged). Some houses can be applied to multiple types, but the seller selects and registers the most preferable type.

Next, a "subcategory" is registered for each house. Subcategories are used when generating the recommendation screen 94 . The seller registers (tags) a subcategory for each house by selecting and ticking off the appropriate one from several features prepared in advance. Examples of such characteristics include "sunlight", "hydrogen station", "storage battery", "fully equipped kitchen", "facing south", "auto lock", "single house", "three stories", and "two households". , "barrier-free", etc., and multiple registrations are made for one house.

Next, a “recommended point” is registered for each house. The “recommended point” is a free one-sentence description of the points that the seller wants to appeal about the house.

Next, "video data" is registered for each house. Although the details will be described later, in this embodiment, the stereoscopic image of the exterior of the house is generated based on CG data, and the stereoscopic image of the interior of the house is generated based on the photographed data. In the housing information database DB1, CG data for generating a three-dimensional image of the exterior of the house (“exterior data”) and photographed data for generating a three-dimensional image of the interior (“interior data”) are stored as “image data”. data"). Therefore, when the seller changes the stereoscopic video of each house, the video data is replaced.

(Processing to generate video)
Next, a description will be given of the process by which the server system 21 generates stereoscopic images of the exhibition zones 74 to 76 based on the registration information in the housing information database DB1.

The group generation unit 34 classifies houses having the same main category (one of "Japanese style", "Urban style", and "Ecology") into the same group among the plurality of houses. As a result, three groups of "Japanese style group", "urban group", and "ecology group" are generated. The condition that the main category to which each house 23 is tagged in the house information database DB1 is "'Japanese style'", "'urban style'" and "'ecology'". correspond to the first condition, and the Japanese style group, the urban group, and the ecological group correspond to the first group.

Next, the space generator 35 generates a stereoscopic image of the exhibition zone based on the three groups generated by the group generator 34 . Here, as described above, the video display unit 36 displays the exhibition zones 74 to 76 in different manners when displaying the overall map screen and when displaying the block screen. For this reason, the space generation unit 35 can display the exhibition zones 74 to 76 in a manner suitable for each of the cases where the purpose is to display them on the overall map screen and when the purpose is to display them on the city block screen. Generate stereoscopic images. Note that the space generation unit 35 corresponds to group generation means.

When the purpose is to display the entire map screen 71, the space generation unit 35 accesses the CG data storage unit 44, and based on the CG data stored in the CG data storage unit 44, displays the entire map screen. 71 stereoscopic video is generated. Then, stereoscopic images of houses and townscapes in each of the exhibition zones 74 to 76 are generated in such an abstract manner that the themes of each of the exhibition zones 74 to 76 can be understood. Further, a stereoscopic image of the portion of the VHP 22 other than the exhibition zones 74 to 76 is generated. As a result, a three-dimensional image for an overall map screen 71 that shows the overall image of the VHP 22 and displays a list of the exhibition zones 74 to 76 is generated.

On the other hand, when the purpose is to display a town block screen, the space generation unit 35 accesses the housing information database DB1, and based on the CG data related to the external appearance information of the housing stored in the housing information database DB1, displays the housing generates a stereoscopic image of the appearance of Furthermore, the CG data storage unit 44 is accessed, and a stereoscopic image of the surrounding environment is generated based on the CG data stored in the CG data storage unit 44 . As a result, a 3D image of the exterior of the house is generated in such a way that the potential customer can experience the feeling of actually being in the townscape, and a 3D image of the surrounding environment suitable for the world view of each of the exhibition zones 74-76. to generate

Further, as described above, the VHP 22 displays the recommendation screen 94 that displays a list of houses that match the preferences of the potential customer by satisfying a predetermined condition. The recommendation screen 94 shows information about each house 23 by character information, and does not include a stereoscopic image. Therefore, the space generation unit 35 is not involved in the generation of the recommendation screen 94, and the image display unit 36 performs the generation processing and then displays it on the information terminal 13 of the potential customer.

(Potential customer information database DB2)
By the way, in generating the recommendation screen 94, the potential customer information of each potential customer registered in the potential customer information database DB2 may be used. First, registration in the potential customer information database DB2 in this embodiment will be described with reference to FIG.

Potential customer information for each potential customer is stored in the potential customer information database DB2. First, the IP address acquisition unit 32 acquires an IP address from the information terminal 13 of the potential customer. Next, the information input unit 33 registers the IP address acquired by the IP address acquiring unit 32 in the potential customer information database DB2. Then, the information input unit 33 stores the potential customer information of the potential customer in the potential customer information database DB2 in association with the registered IP address.

The potential customer information stored in the potential customer information database DB2 is broadly classified into information registered by the potential customer operating the information terminal 13 and information automatically registered by the server system 21 .

The information registered by the potential customer operating the information terminal 13 includes items such as the potential customer's "nickname", "planned place of residence", "planned number of people to reside", and "things of interest". Examples of “interesting things” include “good sunlight”, “strength against disasters”, “safety and security”, “raising children”, “consideration for the environment”, and “barrier-free”. Among the elements that are required for housing, typical ones are listed. Although the details will be described later, these pieces of information are registered when the potential customer inputs answers to the questionnaire input screen 61 when entering the VHP 22 . In other words, if a potential customer does not answer the questionnaire upon entering VHP 22, they are unregistered.

Information automatically registered by the server system 21 includes visit time information in which the visit time of the potential customer visiting the VHP 22 is registered in minutes. Visiting time information includes visiting hours for each zone, visiting hours for the exterior of each house (hereinafter referred to as "visiting hours for each house (outside)"), and visiting hours for the interior of each house (hereinafter referred to as "visiting times for each house ( and the sum of the visit time for each house (exterior view) and the visit time for each house (interior view) (hereinafter referred to as "visit time for each house (total)"). ing. The tour time information is acquired by the behavior pattern information acquisition unit 38 and sequentially registered in the potential customer information database DB2 by the information input unit 33 .

(Processing Executed by Server System 21)
Next, the flow of processing executed by the server system 21 to generate the recommendation screen 94 will be described with reference to FIGS. 12 to 15. FIG. Note that the control processing shown in FIGS. 12 to 15 is repeatedly executed at a predetermined time cycle.

In step S 11 , it is determined whether or not the information terminal 13 of the potential customer has accessed the VHP 22 via the Internet 11 . If the determination is YES, the process proceeds to step S12, and if the determination is NO, the process ends.

In step S12, the IP address acquisition unit 32 acquires IP address information from the information terminal 13 of the potential customer. The information input unit 33 accesses the potential customer information database DB2 and registers the obtained IP address information. Then, the process proceeds to step S13.

In step S13, the video display unit 36 displays the start screen 51 shown in FIG. The start screen 51 displays an agreement icon 52 and a refusal icon 53 for the potential customer to express his/her intention regarding questionnaire input, and an end icon 54 for the potential customer to leave the VHP 22 . It should be noted that answering the questionnaire is optional, and it is possible to enter the VHP 22 without answering the questionnaire. Then, it progresses to step S14.

In step S14, it is determined whether the potential customer has selected the end icon 54 or not. A YES determination advances to step S99. If the determination is NO, the process proceeds to step S15.

In step S99, the display of the VHP 22 of the information terminal 13 is ended. After that, this process is terminated.

In step S15, it is determined whether or not the potential customer has agreed to answer the questionnaire. If the potential customer selects the consent icon 52 on the start screen 51, the determination is YES and the process proceeds to step S16. On the other hand, if the refusal icon 53 is selected, the process proceeds to step S21.

In step S16, the video display unit 36 displays the questionnaire input screen 61 shown in FIG. On the questionnaire input screen 61, there are input fields 62 for inputting information such as "nickname", "planned place of residence", "number of households", and "things of interest" such as "good sunlight" and "safety and security". A check box 63 is displayed for selecting the appropriate one from among a plurality of candidates. Further, an answer completion icon 64 and an answer stop icon 65 are displayed on the questionnaire input screen 61 . The potential customer can complete their response to the questionnaire by selecting the completed response icon 64 . Also, by selecting the answer stop icon 65, the user can stop answering the questionnaire and enter the VHP 22 without answering the questionnaire. Then, it progresses to step S17.

In step S17, it is determined whether or not the potential customer has selected the reply stop icon 65. FIG. If the determination is YES, the process proceeds to step S21. If the determination is NO, the process proceeds to step S18.

In step S18, it is determined whether or not the potential customer has completed answering the questionnaire. In this embodiment, it is not necessary for the potential customer to fill in all the items of the questionnaire, and even if there are unanswered items, the answer to the questionnaire is completed when the potential customer selects the answer completion icon 64. . If the potential customer selects the answer completion icon 64, the determination is YES and the process proceeds to step S19. If the potential customer has not selected the answer completion icon 64, NO is determined, and the process returns to step S17 to repeat the process. That is, the questionnaire input screen 61 continues to be displayed until the potential customer selects the reply stop icon 65 or the reply completion icon 64 .

In step S19, the information input unit 33 registers the contents of the potential customer's answers on the questionnaire input screen 61 as potential customer information in the potential customer information database DB2. As described above, the potential customer information is registered in the potential customer information database DB2 shown in FIG. 11 while being associated with the IP address of the potential customer registered in step S12. Then, the process proceeds to step S21.

In step S21, the video display unit 36 displays the overall map screen 71 shown in FIG. 4 on the potential customer's information terminal. At this time, the space generation unit 35 generates a stereoscopic image of the entire map of the VHP 22 based on the CG data stored in the CG data storage unit. Then, the video display unit 36 displays the stereoscopic video of each of the exhibition zones 74 to 76, the block screen display icon 77 corresponding to each of the exhibition zones 74 to 76, and the potential customer returns to the start screen 51 on the overall map screen 71. and an exit icon 79 for the potential customer to exit the VHP 22. Subsequently, the process proceeds to step S22.

At step S22, it is determined whether the potential customer has selected the return icon 78 or not. If the determination is YES, the process returns to step S13 and each process is repeated. If the determination is NO, the process proceeds to step S23.

At step S23, it is determined whether the potential customer has selected the end icon 79 or not. In the case of YES determination, the process proceeds to step S99, the display of the VHP 22 of the information terminal 13 is terminated, and this processing is terminated. If the determination is NO, the process proceeds to step S23.

In step S24, it is determined whether or not the potential customer has selected any of the block screen display icons 77. FIG. If the determination is YES, the process proceeds to step S31. In the case of NO determination, the process returns to step S22 and each process is repeated. That is, the display of the entire map screen 71 continues until the potential customer selects the return icon 78 or the end icon 79 .

In step S31, the video display unit 36 displays the town block screen of the exhibition zone associated with the selected town block display icon 77 (for example, the block screen 81 of the urban zone 75 shown in FIG. 5). At this time, the space generation unit 35 generates a stereoscopic image of the exterior of the house 23 based on the CG data (appearance data) registered for each house in the house information database DB1, and the stereoscopic image is stored in the CG data storage unit. A three-dimensional image of the surrounding environment of the house 23 is generated based on the CG data received. As described above, the image display unit 36 displays the three-dimensional image of the exterior of the house 23, the three-dimensional image of the surrounding environment of the house 23, the display switching area associated with each house, and the entire area on the block screen 81. A return icon 82 for returning to the map screen 71 and an end icon 83 for ending the VHP 22 are displayed. Then, the process proceeds to step S25.

In step S32, the timer 49 is set in order to acquire the tour time information for each zone of the potential customer. Then, the process proceeds to step S33.

In step S33, update of the numerical value of the visit time for each zone registered in association with the IP address of the potential customer is started in the potential customer information database DB2. In this embodiment, since the tour time information is registered in minutes, the zone-by-zone tour time is incremented every time one minute elapses. The information input unit 33 executes the process of adding a numerical value to the potential customer information database DB2. Then, the process proceeds to step S34.

In step S34, it is determined whether or not the potential customer has selected the return icon. If the determination is YES, the process proceeds to step S35. If the determination is NO, the process proceeds to step S36.

In step S35, the process of updating the value of the tour time for each zone registered in the potential customer information database DB2 in association with the IP address of the potential customer is stopped. Subsequently, the process returns to step S21 and each process is repeated. It should be noted that the value of the tour time for each zone is not reset even if the update is stopped, and the tour time is added to the previous value when the updating process is restarted.

In step S36, it is determined whether the potential customer has selected the end icon 79 or not. If the determination is YES, the process proceeds to step S37. If the determination is NO, the process proceeds to step S38.

In step S37, similarly to step S34, the process of updating the value of the visit time for each zone registered in the potential customer information database DB2 in association with the IP address of the potential customer is stopped. Subsequently, the process proceeds to step S99, the display of the VHP 22 of the information terminal 13 is terminated, and the present processing is terminated.

In step S 38 , it is determined whether or not the potential customer has entered any of the display switching areas 84 on the city block screen 81 . If the determination is YES, the process proceeds to step S41, and the display form is switched to the display 85 for exterior viewing of the house corresponding to the display switching area 84. FIG. If the determination is NO, the process returns to step S34 and each process is repeated.

In step S41, a house-by-house tour time totaling process for totaling the house-by-house tour time of the potential customer is executed. Detailed processing in step S41 will be described later.

In the subsequent step S42, it is determined whether there is any of the exhibition zones 74 to 76 for which the zone-by-zone tour time for the potential customer, which is sequentially updated on the potential customer information database DB2, reaches 60 minutes or longer. judge. If there is an exhibition zone that the potential customer has been observing for 60 minutes or longer, a YES determination is made and the process proceeds to step S43. In the case of NO determination, the process returns to step S34 and each process is repeated.

In step S43, a recommendation screen 94 is displayed based on the potential customer's visit time for each house aggregated by the house tour time aggregation process in step S41 and the potential customer information registered in the potential customer information database DB2 in step S18. A process of generating a "recommended group" that is a set of houses to be built (hereinafter referred to as "recommended group generation process") is executed. The recommended group generation process is executed by the group generation unit 34 . Detailed processing in step S43 will be described later.

In subsequent step S44, it is determined whether or not a recommended group has been generated by the recommended group generation process of step S43. If the determination is YES, the process proceeds to step S45. In the case of NO determination, the process returns to step S34 and each process is repeated.

In step S45, the image display unit 36 generates a recommendation display icon (for example, the recommendation display icon 99 shown in FIG. 9) as a guidance message to the recommendation screen 94 on the block screen 81. FIG. After that, the process proceeds to step S46.

In step S46, it is determined whether the potential customer has selected the recommendation display icon 99 or not. If the determination is YES, the process proceeds to step S47. In the case of NO determination, the process returns to step S34 and each process is repeated.

In step S47, similarly to steps S35 and S37, the process of updating the value of the tour time for each zone registered in the potential customer information database DB2 in association with the IP address of the potential customer is stopped. Subsequently, the process proceeds to step S51.

In step S51, the video display unit 36 generates and displays a recommendation screen 94 shown in FIG. 8 based on the recommendation group generated in step S43. The recommendation screen 94 displays a list 95 of houses belonging to the recommendation group, a return icon 97 for returning to the block screen, and an end icon 98 for ending the VHP 22 . In the list, product names and recommended points are listed for each house.

In addition, although the details will be described later, the contents of the recommended group are updated over time. Therefore, the video display unit 36 displays the recommendation screen based on the content of the recommendation group at the time when the potential customer selects the recommendation display icon. Then, the process proceeds to step S52.

In step S52, it is determined whether or not the potential customer has selected the return icon displayed on the block screen. If the determination is YES, the process proceeds to step S53. In the case of NO determination, the process returns to step S31 and each process is repeated.

In step S<b>53 , it is determined whether or not the potential customer has selected the end icon 98 displayed on the recommendation screen 94 . In the case of YES determination, the process proceeds to step S99, the display of the VHP 22 of the information terminal 13 is terminated, and this processing is terminated. If the determination is NO, the process proceeds to step S54.

In step S<b>54 , it is determined whether or not the potential customer has selected any of the product names of the houses listed in the list on the recommendation screen 94 . In the case of a YES determination, the process proceeds to step S41, which will be described later, in order to display the selected house in the exterior view display. In the case of NO determination, the process returns to step S52 and each process is repeated.

(Tour time total processing)
Next, the tour time tallying process executed in step S41 will be described. FIG. 14 is a subroutine showing tour time counting processing.

In step S101, the image display unit 36 changes the display form on the information terminal 13 of the potential customer to the appearance tour display 85 (see FIG. 6) of the house 23 corresponding to the display switching area 84 into which the potential customer has entered. switch. Further, when the potential customer selects one of the product names of the houses 23 listed in the list on the recommendation screen 94, the video display unit 36 displays the selected house 23 for exterior viewing. Indicated by 85. Then, the process proceeds to step S102.

In step S102, the timer 49 is set in order to obtain information on the visit time (appearance) for each house of the potential customer. Then, the process proceeds to step S104.

In step S104, the information input unit 33 accesses the potential customer information database DB2, and inputs the numerical value of the viewing time (appearance) for each house registered in the potential customer information database DB2 in association with the IP address of the potential customer. Update. In this embodiment, since the tour time information is registered in minutes, the numerical value of the tour time for each zone is updated every time one minute elapses. Then, the process proceeds to step S105.

In step S105, it is determined whether or not the potential customer has selected the interior view display icon 86 displayed on the house in the exterior viewing display 85 state. If the determination is YES, the process proceeds to step S107. If the determination is NO, the process proceeds to step S106.

In step S106, it is determined whether the potential customer has selected the return icon 87 or not. If the determination is YES, this subroutine process ends. In the case of NO determination, the process returns to step S104 and each process is repeated.

On the other hand, if the process proceeds to step S107, the process of updating the numerical value of the viewing time (appearance) for each house registered in association with the IP address of the potential customer in the potential customer information database DB2 is stopped. Then, the process proceeds to step S111. Note that the visit time (exterior) value for each house will not be reset even if the update is canceled. there is

In step S111, the video display unit 36 displays the interior view screen 91 regarding the house corresponding to the interior view display icon 86 selected by the potential customer (see FIG. 7). At this time, the space generation unit 35 generates a stereoscopic image of the interior of the house 23 based on the photographed data (interior view data) registered for each house in the house information database DB1. Then, the video display unit 36 displays a three-dimensional video of the interior of the house 23 and a return icon 92 for returning the display of the information terminal 13 to the exterior viewing display 85 on the interior view screen 91 . Then, the process proceeds to step S112.

In step S112, the timer 49 is set in order to acquire information about the viewing time (introspection) for each house of the potential customer. Then, the process proceeds to step S113.

In step S113, the information input unit 33 accesses the potential customer information database DB2, and inputs the numerical value of the viewing time (introspection) for each house registered in the potential customer information database DB2 in association with the IP address of the potential customer. Update. In the present embodiment, since tour time information is registered in minutes, the value of the tour time for each zone is added every time one minute elapses. Then, the process proceeds to step S114.

In step S114, it is determined whether the potential customer has selected the return icon 92 or not. In the case of YES determination, the process returns to step S101 and each process is repeated. In the case of NO determination, the process proceeds to step S115.

In step S115, the process of updating the numerical value of the viewing time (introspection) for each house registered in association with the IP address of the potential customer in the potential customer information database DB2 is stopped. Subsequently, the process returns to step S101 and each process is repeated. In addition, the number of visit hours (introspection) for each house will not be reset even if the update is canceled. there is

In addition, although not shown, in this embodiment, the visit time (exterior view) for each house and the visit time (interior view) for each house are sequentially added up, and the visit time (calculated) for each house in the potential customer information database DB2 is calculated. ).

(Recommended group generation processing)
Next, the recommended group generation process executed by the group generation unit 34 in step S43 will be described. FIG. 15 is a subroutine showing recommended group generation processing.

The group generation unit 34 can generate groups based on the potential customer's housing preference information. Housing preference information can then be obtained based on the viewing time information on the VHP 22 of the potential customer. For example, by specifying that the potential customer has stayed in the same place for a certain period of time or more, it is possible to specify the target that the potential customer is interested in.

Therefore, first, in step S211, it is determined whether or not there is one exhibition zone for which the visit time for each zone is 60 minutes or longer. If the determination is YES, it is presumed that the potential customer is interested in the house 23 displayed in the one exhibition zone, and the process proceeds to step S212. On the other hand, if the determination is NO, the process proceeds to step S213.

In step S212, the house to be extracted to the recommended group is set to the house displayed in one exhibition zone for which the visit time for each zone is 60 minutes or longer. Then, the process proceeds to step S221.

In step S213, it is determined whether or not there are two exhibition zones for which the visit time for each zone is 60 minutes or longer. If the determination is YES, it is presumed that the potential customer is interested in the houses 23 displayed in the two exhibition zones, and the process proceeds to step S214. On the other hand, if the determination is NO, it is presumed that the potential customer is interested in the houses 23 exhibited in all exhibition zones, and the process proceeds to step S215.

In step S214, the houses 23 to be extracted into the recommended group are set to the houses displayed in the two exhibition zones for which the visit time for each zone is 60 minutes or longer. Then, the process proceeds to step S221.

In step S215, the houses 23 to be extracted to the recommended group are set to the houses 23 exhibited in all the exhibition zones (that is, all the houses 23 present in the VHP 22). Then, the process proceeds to step S221.

That is, in steps S211 to S215, an exhibition zone that matches the interest of the potential customer is estimated based on the length of stay, and the houses 23 to be aggregated into the recommended group are placed in the estimated exhibition zone. It means that the process of limiting to belonging is executed.

Also, in each house 23, it can be estimated that the longer the potential customer stayed, the stronger the potential customer's interest. Therefore, in step S221, among the houses 23 set as extraction targets in steps S212, S214, or S215, the house 23 with the longest house-by-house visit time (total) (that is, the house 23 ranked first) is specified. Then, the process proceeds to step S222.

In step S222, it is determined whether or not there is a house 23 that has been visited by the potential customer in addition to the house 23 specified in step S221 among the houses 23 set as extraction targets in steps S212, S214, or S215. . If the determination is YES, the process proceeds to step S223. If the determination is NO, the process proceeds to step S224.

In step S223, the house 23 to be analyzed is set in the process executed in subsequent step S241. In this step S223, the house with the highest house-by-house visit time (total) specified in step S221 is set as an analysis target. Then, the process proceeds to step S241.

In step S224, among the houses 23 set as extraction targets in steps S212, S214, or S215, the house 23 having the second longest visit time (total) for each house (that is, the second-ranked house 23) is specified. do. Then, the process proceeds to step S222.

In step S225, among the houses 23 set as extraction targets in steps S212, S214, or S215, houses visited by potential customers other than the houses 23 specified in steps S221 and 23 specified in steps S225 23 is determined. If the determination is YES, the process proceeds to step S231. If the determination is NO, the process proceeds to step S226.

In step S226, it is determined whether or not the house visit time (total) of the house 23 ranked first is three times or more as long as the house visit time (total) of the house 23 ranked second. In the case of a YES determination, the process proceeds to step S223, and only the first-ranked house 23 is set as an analysis target. In the case of NO determination, the process proceeds to step S227. In other words, if it is considered that there is a large difference in the visit time (total) for each house between the first-ranked house 23 and the second-ranked house 23, the second-ranked house 23 is excluded from the analysis targets. ing.

In step S227, the house 23 to be analyzed is set in the process executed in subsequent step S241. In this step S227, the house 23 ranked first and the house 23 ranked second in terms of house-by-house visit time (total) are set as objects to be analyzed. Then, the process proceeds to step S241.

Further, in step S231, among the houses 23 set as extraction targets in steps S212, S214, or S215, the house 23 having the third longest house visit time (total) (that is, the house 23 ranked third) is specified. do. Then, the process proceeds to step S232.

In step S232, it is determined whether or not the house visit time (total) of the house 23 ranked second is three times or longer than the house visit time (total) of the house 23 ranked third. If the determination is YES, the process proceeds to step S226. In the case of NO determination, the process proceeds to step S233. In other words, when it is considered that there is a large difference in the visit time (total) for each house between the 2nd ranked house 23 and the 3rd ranked house 23, the 3rd ranked house 23 is excluded from the analysis targets. ing.

In step S227, the house 23 to be analyzed is set in the process executed in subsequent step S241. In this step S227, the house ranked 1st, 2nd, and 3rd in visit time by house (total) are set as analysis targets. Then, the process proceeds to step S241. That is, in this embodiment, a maximum of three houses 23 are set as analysis targets. When the number of residences 23 visited by potential customers is less than three, or when there are residences 23 considered unsuitable for analysis, the number of residences 23 set as analysis targets is less than three. Sometimes.

As described above, in steps S221 to S223 and S231 to S233, the top three houses 23 that are presumed to be of interest to the potential customer are identified based on the length of stay. Become.

Then, it can be estimated that the characteristics of the house 23 in which the potential customer stayed for a particularly long time are the points (corresponding to the house preference information) that the potential customer attaches importance to when selecting a house. In addition, if there are multiple houses 23 where the potential customer has stayed for a long time, it is possible that the features shared by those multiple houses 23 are the points that the potential customer attaches importance to when selecting a house. considered to be high.

Therefore, in step S241, the analysis processing regarding the subcategory items of the housing information database DB1 is executed for the house 23 set as the analysis target in step S223, S241 or S233. More specifically, when the house 23 to be analyzed is set in step S214, that is, when only the house 23 ranked first in visit time (total) by house is to be analyzed, among the items of the subcategories, the Identify what is tagged to the first ranked house 23 . Further, when the house 23 to be analyzed is set in step S241 or S233, that is, when a plurality of houses 23 are to be analyzed, a tag is common to the plurality of houses 23 among the items of the subcategories. Identify what is attached. The item of the subcategory specified in this step S241 corresponds to the potential customer's housing preference information.

In addition, in the analysis processing in step S241, for some subcategory items, if the numerical balance between the visit time for each house (exterior) and the visit time for each house (interior) does not satisfy a predetermined condition. is not identified as an item in the subcategory that the house is tagged with.

Specifically, for example, the items in the subcategory of "fully equipped kitchen" are considered to be related only to the interior and not to the exterior. Therefore, even if a potential customer visits a house for a long period of time, if he/she only observes the exterior of the house 23 instead of the interior, he or she may not be interested in the kitchen area and may be interested in other things. It is presumed that he was visiting the house 23 at that time. For this reason, if the visit time for each house (interior view) for a certain house 23 is less than 1/10 of the visit time for each house (outside view), even if the house 23 is tagged with "fully equipped kitchen". Even if it is, "fully equipped kitchen" is not specified as an item of the subcategory tagged to the house 23 . This makes it possible to obtain more accurate housing preference information. Subsequently, the process proceeds to step S242.

In step S242, it is determined whether or not the subcategory item has been specified in the analysis processing of step S241. In the analysis process of step S241, when a plurality of houses 23 are analyzed, there may be no subcategory items tagged in common to the plurality of houses 23. FIG. In that case, the subcategory item cannot be specified in step S241. Therefore, if the item of the subcategory can be specified, the determination is YES, and the process proceeds to step S243. On the other hand, if the item of the subcategory could not be specified, NO determination is made, and this subroutine processing ends. It should be noted that the control process by the server system 21 is continued even if the determination in step S242 is NO. Therefore, if the potential customer continues to tour the VHP 22 and the value of the visit time (total) for each house changes, there is a possibility that the item of the subcategory will eventually be specified.

As described above, in step S241, based on the characteristics (common) of the (plural) houses 23 in which the potential customer has stayed for a particularly long time, the points that the potential customer attaches importance to when selecting a house are determined. It is estimated.

As for the houses 23 that the potential customer has not yet visited, those having the "points that the potential customer attaches importance to when selecting a house" estimated in step S241 are selected among the houses 23 that have been visited. It is thought that there is a possibility that potential customers will show interest in the same way as those with long stays.

Therefore, in step S243, from among the houses 23 set as extraction targets in steps S212, S214, or S215, "At least one of the subcategory items identified in step S241 is tagged with an item of the same subcategory. Houses 23 that satisfy the condition "there is a house" are extracted. Then, the process proceeds to step S244. Note that the condition "at least one of the subcategory items identified in step S241 is tagged with an item of the same subcategory" is the house 23 set in step S212 (that is, in the same exhibition zone). When a house 23) located in is to be extracted, it corresponds to the second condition. When the houses 23 set in step S214 or S215 (that is, houses 23 in two or more different exhibition zones) are to be extracted, this corresponds to the third condition.

In step S244, it is determined whether or not the number of houses 23 extracted in step S241 is five or less. If the determination is YES, the process proceeds to step S245. In the case of NO determination, the process proceeds to step S243.

In the control processing up to this point, by identifying that the potential customer has stayed in the same place for a certain period of time or longer, the object of interest to the potential customer has been identified. That is, based on stay time information as action pattern information, housing preference information is acquired. However, there are other possible methods for identifying targets that potential customers are interested in. For example, based on information obtained from interviews with potential customers including questionnaires (i.e., information equivalent to potential customer information) can also be used to identify subjects of interest to potential customers.

Therefore, in this embodiment, when the number of houses aggregated into the recommended group exceeds a predetermined number, the potential customer information (that is, the potential customer information registered in the potential customer information database DB2 based on the entrance questionnaire) Based on this information), the houses included in the recommended group are further limited.

In step S245, based on the items registered in the potential customer information database DB2 in step S18 and selected by the potential customer as "things of interest" in the questionnaire, out of the houses 23 extracted in step S241, a house 23 is further extracted.

Specifically, each item of "things of interest" is pre-associated with relevant subcategory items of the housing information database DB1. For example, the item ``good sunlight'' in ``things of interest'' is associated with the item ``facing south'' in the subcategory of the housing information database DB1. ' is associated with the subcategory items 'sunlight', 'hydrogen station' and 'storage battery' in the housing information database DB1.

Then, the condition that "at least one of the subcategory items of the housing information database DB1 associated with the items registered as 'interesting things' of the potential customer is tagged" is satisfied. The house 23 where the user is located is extracted from the houses 23 extracted in step S243. After that, the process proceeds to step S246. The items of the subcategories of the house information database DB1 used for the process of extracting the house 23 in step S243 correspond to the potential customer's house preference information.

In step S246, it is determined whether or not the number of houses 23 extracted in step S245 is five or less. If the determination is YES, the process proceeds to step S247. If the determination is NO, this subroutine process ends. In other words, the number of extracted houses 23 cannot be narrowed down to five or less even after the two-step extraction process based on the potential customer's visit time information and the extraction process based on the potential customer's questionnaire results. , no recommendation group is generated at that time.

In step S247, a recommended group is generated from the houses 23 extracted in the steps up to this point. Specifically, if the determination in step S244 is YES, a recommended group is generated from the houses 23 extracted in step S243. If the determination in step S244 is NO and the determination in step S246 is YES, a recommended group is generated from the houses 23 extracted through the two-step extraction process of steps S243 and S245. After that, the subroutine processing is terminated.

Note that the recommended group generated in this subroutine process is generated by extracting the houses 23 from among the houses 23 displayed in one exhibition zone when the determination in step S211 is YES. case, it corresponds to the second group. In this case, in step S245, "At least one of the subcategory items of the housing information database DB1 associated with the items registered as 'interesting things' of the potential customer is tagged." corresponds to the second condition.

Further, if the determination in step S211 is NO, that is, if a recommended group is generated by extracting houses from among the houses 23 exhibited in two or more exhibition zones, the recommended group is: It corresponds to the third group. In this case, the extraction condition in step S245 corresponds to the third condition. It is also conceivable that the houses 23 that make up the recommended group are only those displayed in the same exhibition zone (that is, belonging to the same first group). The recommended group corresponds to the third group.

As shown in FIGS. 6 and 7, the video display unit 36 displays the interested icon 96 on the individual display screens of each house 23 (that is, the exterior viewing display 85 and the interior viewing screen 91). there is When the potential customer selects the interested icon 96 on the information terminal 13, the video display unit 36 displays a guidance screen (not shown). The guidance screen displays three desired icons, ie, "request for materials", "request for field visit", and "request for individual consultation", from which the potential customer can select a desired item. When the potential customer selects one of the three desired icons, the video display unit 36 displays a contact input screen (not shown). On the contact information input screen, potential customers enter contact information such as names, addresses, telephone numbers, and e-mail addresses. The contact information input on the contact input screen is stored in the potential customer information database DB2 by the information input unit 33 as the house 23 that the potential customer is viewing (that is, the house 23 for which the potential customer has selected the interested icon). Link and register. These registration information are notified to the management terminal 14 via the Internet 11 . As a result, the seller can view the contact information registered in the potential customer information database DB2 through the management terminal 14. FIG. Therefore, the seller can contact the potential customer based on the registered contact information and proceed with specific business negotiations.

(Effect)
According to the configuration of the present embodiment described in detail above, the following excellent effects are obtained.

(1) Of the plurality of houses 23 owned by the VHP 22, those that satisfy the same first condition are aggregated into the same first group. Exhibit zones 74 to 76 are generated for each first group to exhibit their respective contents. That is, among the plurality of houses 23, those that satisfy the same first condition are aggregated and exhibited in the same exhibition zone. For this reason, a wide variety of houses 23 are exhibited in the VHP 22, and potential customers can efficiently find the houses 23 by viewing those that meet their desired conditions from among the exhibition zones 74-76. can be visited.

(2) The entire VHP 22 is displayed on the overall map screen 71, and a list of a plurality of exhibition zones 74 to 76 provided within the VHP 22 is displayed. The block screen of each of the exhibition zones 74 to 76 displays the contents of each exhibition zone in more detail than the VHP 22. FIG. Therefore, the potential customer can select an exhibition zone to visit by first looking at the overall map screen 71 . By looking at the block screen of each exhibition zone 74-76, the contents of each exhibition zone 74-76 can be seen in more detail. That is, since the potential customer can narrow down the object to be visited in stages, the potential customer can tour the house 23 more efficiently.

(3) On the street block screen, a three-dimensional image of the surrounding environment is displayed together with the appearance of the house 23 . As a result, the potential customer can enjoy not only the house 23 itself provided in the exhibition zone, but also the townscape around the house in an expanded image. As a result, the potential customer is motivated to tour the house.

(4) For example, the Japanese-style zone 74 and the like are not displayed on the block screen 81 of the urban zone 75 . That is, other exhibition zones and the like are not displayed on the block screen of a certain exhibition zone. Therefore, it is possible to prevent the atmosphere of the exhibition zone from being spoiled by the reflection of other exhibition zones.

(5) A display switching area 84 corresponding to each house 23 is displayed on the block screen 81 . When the potential customer enters the display switching area 84 , the display form on the information terminal 13 of the potential customer is switched to the exterior viewing display 85 for viewing the exterior of the corresponding house 23 . In the exterior viewing display 85, the potential customer can operate the information terminal 13 to view stereoscopic images of the exterior of the house 23 from all angles. This allows potential customers to get a better idea of what your home will look like.

(6) As described above, the VHP 22 classifies a plurality of houses 23 into a plurality of exhibition zones 74-76 according to the first condition. However, the classification according to the first condition is not necessarily a convenient classification for all potential customers. For example, for a certain potential customer, the classification by the exhibition zones 74 to 76 is a rough one, and it is assumed that it is preferable to have more detailed classification (zoning) within the same exhibition zone. . For this reason, a second condition different from the first condition is set, and among the houses classified into the same exhibition zone, those that satisfy the second condition are aggregated to generate a second group (that is, a recommended group). It's like That is, since the exhibition zones 74 to 76 generated according to the first condition can be further divided into layers (zones), it is possible to improve the ease of searching for houses.

(7) A recommendation group as a second group is generated based on housing preference information regarding the potential customer's preferences regarding housing. Then, the houses 23 included in the recommended group are displayed as a list 95 on the recommended screen 94 . Therefore, the potential customers can more efficiently tour the houses that suit their tastes in one exhibition group.

(8) It is conceivable that, depending on the potential customer, classification based on another viewpoint is preferable to classification based on the exhibition zones 74 to 76 generated according to the first condition. For this reason, a third condition different from the first condition is set, and those of the plurality of houses 23 that meet the third condition are aggregated from the plurality of exhibition zones 74 to 76 into a third group (that is, a recommended group). ) is generated. By presenting the houses aggregated to the third group to potential customers, it is possible to improve the ease of searching for houses.

(9) A recommended group as a third group is generated based on housing preference information regarding potential customers' preferences regarding housing. Then, the houses 23 included in the recommended group are displayed as a list 95 on the recommended screen 94 . Therefore, when a potential customer wants to visit a plurality of exhibition zones 74 to 76 to see a house that matches his or her taste, the potential customer can repeatedly visit the plurality of exhibition zones 74 to 76 by viewing the recommendation screen 94. It is efficient because you can visit a house that suits your taste without switching.

(10) Potential customer's housing preference information is acquired based on visit time information as potential customer behavior pattern information in VHP 22 and potential customer information registered in potential customer information database DB2. . For this reason, the seller can propose a house that suits each potential customer's taste without communicating with the potential customer.

(11) When executing the process of extracting the house 23, it is acquired based on the house preference information acquired based on the potential customer's visit time information in the VHP 22 and the potential customer information registered in the potential customer information database DB2. and housing preference information are appropriately used together. Thereby, it is possible to adjust so that the number of houses 23 included in the recommended group does not become too large. Then, the house 23 that does not suit the potential customer's taste can be excluded from the recommendation group with higher accuracy.

(12) A recommended group as a second group or a third group is generated based on the housing preference information. Also, when the block screen 81 is displayed, a recommendation display icon 99 is displayed on the block screen 81 as a guidance message. Furthermore, when the potential customer selects the recommendation display icon 99 on the information terminal 13, a list 95 listing the names of the houses 23 belonging to the third group is displayed on the information terminal 13. FIG. Thereby, the potential customer can be urged to see the third group. Then, it is possible to form a flow that guides the potential customer to a house that matches the potential customer's taste. In this case, the recommended group is highly likely to match the potential customer's housing preference, so a high sales promotion effect can be expected.

(Other embodiments)
The present invention is not limited to the above embodiments, and may be implemented as follows, for example.

(a) In the above embodiment, the themes of the exhibition zones 74 to 76 (that is, the first group) are "Japanese style", "Urban type" and "Ecology", but are not limited to these. In addition to this, you can freely set themes such as "luxury housing", "villa", and "for family households". Also, the number of exhibition zones is not limited.

(b) In the above embodiment, when a potential customer enters a predetermined exhibition zone 74-76, other exhibition zones 74-76 are not displayed. Instead of this, image processing may be performed by the control unit 31 so that the other exhibition zones and the like are displayed in a lighter color so as to make them difficult to see.

(c) In the above embodiment, the housing preference information is acquired by the server system 21 . Then, the case where it is acquired based on the tour time information as the behavior pattern information of the potential customer in the VHP 22, and the tour time information as the behavior pattern information of the potential customer in the VHP 22 and the potential customer information registered in the potential customer information database DB2. There are cases where it is obtained based on However, the method of acquiring housing preference information is not limited to this. For example, the housing preference information may be obtained based only on the potential customer information registered in the potential customer information database DB2.

(d) In the above embodiment, the recommended screen 94 is generated in a table format that does not include stereoscopic video based on the recommended groups as the second group and the third group, but the present invention is not limited to this. Since the image display unit 36 can also generate a stereoscopic image based on the second group and the third group, it may display a recommendation screen including the stereoscopic image. For example, a stereoscopic image of the exterior of the house 23 may be displayed in the list. Also, like a town block screen, a stereoscopic image of the exterior of a house and a stereoscopic image of the surrounding environment may be generated to express a townscape (that is, to generate a virtual exhibition zone).

(e) In the above embodiment, when generating a recommended group as the second group or the third group, determination is made based on the potential customer's housing preference information. Adding to the criteria is not mandatory. Grouping may be performed based only on the intention of the seller, or recommended groups may be generated based on predetermined conditions freely set by the seller in advance.

For example, the seller can predetermine the second condition as ``the solar panel subcategory must be checked''. In this case, a second group, which is a set of "houses with solar panels", can be generated within each first group. Furthermore, based on the second group, it is also possible to create an area of houses with solar panels in each of the exhibition zones 74-76. That is, the houses displayed in the same exhibition zone are displayed after being further classified according to the second condition that "the solar panel subcategory is checked". This allows the seller to effectively appeal to potential customers by highlighting homes with solar panels. A potential customer desiring a house with solar panels can tour the house efficiently.

Further, the condition that "the subcategory of solar panel is checked" may be set in advance as the third condition. In this case, a third group can be generated by aggregating "houses with solar panels" from a plurality of first groups. Furthermore, based on the third group, a three-dimensional image of each house is generated, and a virtual exhibition zone in which houses with solar panels are gathered is displayed, different from the exhibition zones 74 to 76 generated based on the first group. It can also be generated separately. In this case, a potential customer who desires a house with solar panels can view all the houses with solar panels displayed on the VHP 22 in the virtual exhibition zone, which is convenient.

(f) In the above embodiment, the number of houses 23 displayed on the recommendation screen 94 was limited to five or less so as not to have too many choices. can be set.

(g) Although there is one recommendation group in the above embodiment, the present invention is not limited to this. For example, another condition may be applied to classify the recommended groups generated in step S247 to generate a plurality of recommended groups. In other words, a fourth condition different from the first to third conditions is set, and out of the houses included in the groups generated based on the second or third conditions, those that satisfy the fourth condition are aggregated. A plurality of groups may be generated. In this case, it is possible to generate a plurality of recommended screens based on the plurality of recommended groups. In addition, it is preferable to display a plurality of guidance messages for prompting the display of recommended screens on the city block screen, corresponding to each recommended screen.

(h) The configuration of each of the exhibition zones 74-76 can be changed by the seller to suit his/her taste at appropriate timing. For this reason, it is possible to adjust the contents of the exhibition by looking at the exhibition status of each housing maker on the VHP 22, and to appeal the type of housing that the seller particularly wants to sell by, for example, creating a special area. Also, the theme may be changed depending on the time of year, for example, "Disaster prevention is the theme for September."

(i) In the above-described embodiment, the information about the staying time in each house 23 is used as the potential customer's behavior pattern information, but the information is not limited to this. For example, it is also possible to use information about the number of times the house 23 has been visited. For example, a method of storing the number of times the corresponding display switching area 84 has been entered for each house 23 is conceivable. Further, even when the information about the staying time in each house 23 is used, detailed analysis may be made to "what part of the interior of each house 23 was viewed". In this case, for example, for a certain potential customer, it is possible to obtain information on the visit time, such as "I spent a long time confirming the kitchen". Then, it is possible to obtain housing preference information by inferring that "the potential customer desires a house with a full kitchen".

(j) In the above embodiment, in the favorite group generation process (specifically, steps S243 and S245), the extraction condition that "at least one of the specified subcategory items is tagged" However, it is also possible to set an extraction condition that "all the items in the specified subcategory are tagged". That is, the search method in the extraction process may be so-called "OR search" or "AND search".

(k) In the above embodiment, the items of "interesting things" registered in the potential customer information database DB2 are registered based on a questionnaire at the time of entry, but the present invention is not limited to this. For example, the seller may communicate with the potential customer by telephone, online chat, or other means, and register the potential customer information obtained therefrom. In this case, the seller operates the management terminal 14, accesses the potential customer information database DB2, and inputs the potential customer information into the information input unit 33. FIG.

(l) In the above embodiment, the VHP 22 is toured in a format similar to Google's Street View (registered trademark). ) to tour the inside of the VHP 22 .

(m) In the above embodiment, the interested icon 96 is displayed while the potential customer is visiting the individual house (that is, while the exterior viewing display 85 and the interior viewing screen 91 are being displayed). The screen displaying the presence icon 96 is not limited to this. For example, the list 95 of the recommendation screen 94 may be displayed for each house 23 .

Further, the screen displaying a list of houses 23 may be other than the recommendation screen 94 of the above-described embodiment. For example, the potential customer information database DB2 stores tour history information about houses that the potential customer has already toured. Then, based on the tour history information, a screen displaying a list of houses that have been toured may be displayed. In addition, a favorite icon (not shown) is displayed on the individual display screen of each house (that is, the exterior viewing display 85 and the interior view screen 91), and the potential customer selects the favorite icon for the house 23. History information is stored in the potential customer information database DB2. In addition, based on the selection history information, only the houses 23 for which the potential customer has selected the favorite icon may be displayed in a list. Then, on the list display screen of these other examples, the interested icon 96 may be displayed for each house so that the house that the user wishes to proceed to the business negotiation with can be selected.
