Description

  The present invention relates to a building sales system using a network.

  In recent years, a sales system using a network has been proposed. In the building sales system, a technology has been proposed in which a virtual model house and a housing exhibition hall are realized in a three-dimensional virtual space, and a business negotiation between a customer and a sales staff is supported via a communication network (Patent Literature). 2 to 4). On the other hand, using the advantages of the network, not only business negotiations between customers and sales staff, but also a system that supports the involvement of third parties who have know-how related to housing construction and supports the realization of customers' home construction has been proposed. (Patent Document 1).

  On the other hand, the acquisition of a house is usually realized through a plurality of stages. Specifically, for example, housing construction and purchase are realized through an information collection stage, a planning / design stage, and a contract stage. The information collection stage is a stage in which a customer collects information about a house through a housing magazine or the Internet. The planning / design stage is a stage for designing a layout of a house. In this stage, the customer may design by himself using the floor plan design software, or may determine the floor plan while consulting with the sales staff of a plurality of housing manufacturers. The contract stage is a stage in which the sales staff performs operations such as arrangement and discounting of housing funds, promise of delivery date and other special provisions. The contract stage has the characteristics that the authority of the contract and the handling of the customer's personal information become problems.

The flowchart which shows the content of the authorization procedure of a house meister. The flowchart which shows an example of the flow of the house building by a customer. The figure which shows the window displayed when starting an exclusive program for external use. The figure which shows the window which shows the information regarding Meister in a program for exclusive use for outside. The schematic diagram which shows the communication environment between a customer and Meister.

  Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

  FIG. 1 is a conceptual diagram showing a home sales system 90 according to an embodiment of the present invention. The home sales system 90 includes a home sales server system 10 for selling homes in a three-dimensional virtual reality space. A database DB1 is connected to the home sales server system 10. The home sales server system 10 is also called a management computer. The database DB1 is also called a storage unit.

  The database DB1 stores a business database DS and a certification level database DL. The business database DS stores housing-related data, customer data, staff data, and the like. The housing-related data includes data such as technical matters and prices (including discountable amounts) for sales staff to use in housing sales. The customer data includes information such as the customer's name and address, and the desired home acquisition location. The staff data includes information such as the sales area and schedule of each sales staff and the operation status (for example, schedule). The contents of the authorization level database DL will be described later.

  The home sales server system 10 is connected to the space generation server system 20 that generates the virtual reality space described above and the Internet 91. The space generation server system 20 is connected to the database DB2. The database DB2 stores image data and vector data such as CG data and live-action data for generating a virtual three-dimensional space.

  The space generation server system 20 can realize a virtual action in Tokyo using an avatar such as meet-me (registered trademark) or Metapolis (registered trademark) that reproduces Tokyo in a three-dimensional space. An avatar is a character that is a part of himself in a virtual reality space, and can perform activities close to reality in terms of walking, visual field, and conversation.

  Terminals such as computers 31, 32, 33 and portable information terminal 34 and computers 51, 52 can be connected to the home sales server system 10 via the Internet 91. The computers 31, 32, 33 and the portable information terminal 34 are terminals operated by an outside person such as an unspecified number of potential customers and certified advisors. The certified advisor means a person who is registered in the certification level database DL as a person who satisfies a preset certification standard. The computers 51 and 52 are computers operated by sales staff.

  Examples of the portable information terminal 34 include tablets and mobile phones such as iPad (registered trademark) and ANDROID (registered trademark). The computers 31, 32, 33 and the portable information terminal 34 operated by the customer are also called customer-side computers.

  A dedicated program PD is installed in the computers 31, 32, 33, 51, 52 and the portable information terminal 34. When the dedicated program PD is installed, it confirms whether the person operating the computer is a customer, an authorized advisor, or a sales staff, and sets usable functions.

  FIG. 2 is a flowchart showing the contents of the installation procedure of the dedicated program PD. In step S11, a third party outside the company downloads an installation program for the dedicated program PD from a predetermined website (not shown). This website may be provided, for example, by the home sales server system 10.

  In step S <b> 12, a third party outside the company installs the dedicated program PD in the own computer 31, 32, 33 or the portable information terminal 34. The dedicated program PD displays a window (not shown) for setting a new ID and password. When the ID and password are input, the home sales server system 10 confirms that the IDs do not overlap, and then stores the ID as a database key and the IP address and password as field data in the sales DS of the database DB1. To do.

  In step S13, a third party outside the company activates the dedicated program PD. A third party outside the company can act as a customer, an authorized advisor, or just a spectator in a virtual space where the home sales server system 10 can be used. The certified advisor means a person who is certified by the operator of the home sales server system 10 and whose ID is registered in the certification level information DL of the database DB1. Certified advisors are also called residential meisters or simply meisters.

  The dedicated program PD transmits the MAC address and IP address of the installed computer components to the home sales server system 10. In the present embodiment, the IP address means a global IP address, and functions as an address representing the destination of an IP packet in the Internet. The MAC address (Media Access Control Address) is a hardware identification address, and is used for identifying a node (computer or the like) on the network.

  The home sales server system 10 generates a hash value based on the MAC address of the component. Examples of the constituent elements include RAM, HDD, and Ethernet (registered trademark) card. The hash value is generated based on the MAC address of the component. The dedicated program PD stores the hash value in the business database DS of the database DB1. The hash value is used to confirm the computer of the customer or Meister.

  The certified advisor means a person who satisfies a preset standard and is registered in the certified level database DL. The onlooker is an unspecified third party who uses the dedicated program PD. The onlooker can also be grasped as a potential customer, that is, a potential customer.

  In step S14, the home sales server system 10 executes an activation process. The activation process is a process of managing the function of the dedicated program PD according to the input ID. The home sales server system 10 can use the Meister function which is a function as a Meister only when the ID is registered in the authorization level information DL of the database DB1. The Meister function includes, for example, a function in which the uniform of the avatar controlled in the three-dimensional virtual space becomes the uniform for Meister and an access function to the house related data stored in the business database DS.

  On the other hand, when the ID is not registered in the authorization level information DL of the database DB1, the home sales server system 10 restricts the function of the dedicated program PD to the function for customers or visitors. The limitation of the function is realized by the activation technology by specifying the computer by the hash value. The activation technique is an authentication process that is generally performed to confirm that a regular license is held after software is installed. Such a management function of the dedicated program PD by the home sales server system 10 is also called a business negotiation restriction function.

  If it is determined that the customer is a customer or a visitor, the home sales server system 10 calculates the address of the access point from the IP address of the computer and registers it as a desired location for home acquisition in the business database DS. However, when the address is registered by the customer, the home acquisition desired place is changed from the address of the access point to the customer's address. Furthermore, when the home acquisition desired place is registered, the registered content is changed to the address.

  FIG. 3 is a flowchart showing the contents of the house meister certification procedure. In step S <b> 21, the operator of the home sales server system 10 sets an accreditation standard for home meisters. Certification standards include, for example, housing qualifications (first-class architects or second-class architects), results of tests on housing knowledge conducted by operators, operation ability of dedicated program PD, or achievements as non-certified advisors. Can be set.

  In step S22, the operator performs an authorization process. The certification process is performed in response to a request from a third party who desires certification. The request requires third-party personal information (name, address, etc.). The operator sends the ID and provisional password by mail to the address. As a result, the authorization is performed after confirming the actual name and address.

  In step S23, the home sales server system 10 executes a registration process. The registration process is a process of registering the Meister in the authorization level information DL. Registration in the authorization level information DL is registered by the home sales server system 10 in response to access of the dedicated program PD that uses the mailed ID and provisional password.

  The registered contents include an ID as a database key, and a name, an address, a certified content, and a certified level are recorded as field data. The contents of certification include, for example, areas where consultation is possible (for example, structure and thermal environment), good consultation areas, and qualification information such as architects. The accreditation level includes an accreditation level of each area such as a structure and a thermal environment and a comprehensive accreditation level. Each accreditation level can be determined by the operator based on various types of information such as the results of the test, the number of experiences, and the results of contracts.

  As described above, a plurality of levels of certification may be included in the certification level of each area and the overall certification level. The determination of matters that can be negotiated may include not only the certification level but also other factors such as loss (for example, a trust relationship with the sales staff). Information that can be used to determine such matters that can be negotiated is called negotiation level information.

  FIG. 4 is a flowchart showing an example of the flow of residential construction by a customer. In step S31, the customer executes a browsing process. The browsing process is a process in which the customer activates the installed dedicated program PD and looks around the contents of the negotiations and the layout of other houses under negotiation by the house sales server system 10. Thereby, the customer can acquire the preliminary knowledge regarding a residential building casually.

  The dedicated program PD displays the entrance to the virtual exhibition hall formed in the three-dimensional space. The business meeting room is provided as a plurality of types of business meeting rooms inside the virtual exhibition hall. The plurality of types of negotiation rooms include a contract negotiation room where only customers and sales staff can enter, and an advice negotiation room where Meister can also enter. In the contract negotiation room, contract templates, specifications, and estimates can be used, and discounts can also be entered. On the other hand, in the consultation business room, a specification sheet and an integrated document are prepared, and as will be described later, entry into the discount amount column is restricted by the program.

  FIG. 5 is an explanatory diagram showing three windows P1, P2, and P3 displayed when the dedicated program PD is activated. In the three windows P1, P2, and P3, icons indicating the preset housing plans at each stage are displayed. In the window P1, an icon 71 indicating the plan at the planning stage is displayed. In the window P2, an icon 72 is displayed that indicates a plan being negotiated with the house Meister. In the window P3, an icon 73 indicating a built plan is displayed.

  The plan at the planning stage is the first plan by the customer. The customer creates a draft plan using the floor plan creation function and appearance creation function provided in the dedicated program PD. The draft plan can be uploaded to the work area of the home sales server system 10 along with customer comments (for example, requests and intentions). The plan uploaded in this way is displayed on the window P1 as an icon. Other customers and Meisters can view the contents of the plan at the planning stage by clicking the icon.

  Other customers, Meisters, and onlookers can leave comments and revision plans for the plan at the planning stage. Comments and revision plans are stored as part of the plan and can be viewed by other third parties as well as plan creators.

  Icons are displayed at the top according to the frequency of access, and those that have not been accessed for a certain period of time are automatically deleted together with related data. However, when the dedicated program PD detects that it has been automatically deleted when accessing the home sales server system 10, it uploads the finally uploaded plan again. Thereby, an unnecessary plan can be efficiently deleted from the home sales server system 10 without impairing customer satisfaction.

  The plan during the negotiation with the housing Meister is a plan during which the Meister and the Meister are negotiating. Other customers, Meisters, and onlookers can see customers and residential Meister deals in real time, so they can anticipate future developments in their deals and use them as a reference. You can also modify your plan. In addition, the plan under negotiation with the house Meister can be made private by the customer's selection as will be described later.

  An already built plan is a plan that has been officially signed and the building is completed. The built plan is published as walk-through content using photographs of the actually constructed building. The walk-through content is content that can be walked in a 360-degree image in an actually constructed building, such as Street View (registered trademark) of Google (registered trademark). As a result, the customer can check the actually constructed building, while the meister and sales staff can also use it for advice to the customer.

  In step S32, the customer starts a business talk with at least one Meister based on the draft of his plan. A business negotiation can be started, for example, as a question from a customer for a revised proposal or comment on the draft of his plan. Customers can know each Meister's past performance and areas of expertise before asking questions. The customer can also select a Meister by performing a design competition (competition). That is, the customer can open the building conditions and requests, solicit multiple proposals, and select an excellent proposal from them.

  After selecting the Meister, the customer can make his plan private, disclose the plan only to the selected Meister, and restrict access to other third parties or specific persons. However, sales staff have access to all plans and are always monitorable. However, access by the sales staff may be limited to plans in the sales area in charge.

  FIG. 6 is an explanatory diagram showing three windows M1, M2, and M3 showing information related to Meister in the dedicated program PD. The window M1 is a window showing a Meister icon 81, which is good at consultation on the housing structure and suitable for floor plan consultation. The window M2 is a window showing a Meister icon 82, which is good at consultation as an interior coordinator and suitable for interior and lighting consultation. The window M3 is a window showing a Meister icon 83, which is good at consultation about the thermal environment and is suitable for consultation of equipment such as air conditioning equipment, bathroom, and kitchen equipment.

  In step S33, the customer selects at least one Meister. Meisters are selected by the customer using the dedicated program PD. When the Meister is selected, the Meister is registered as field data of the customer record (data) in the sales database DS, and the selected Meister is also notified from the home sales server system 10. As a result, the Meister starts a business negotiation with the customer to create a contract plan. On the other hand, customer information is registered in the authorization level database DL as field data of Meister records (data).

  In step S34, the Meister consults with the customer on the housing plan and specifications such as the floor plan, appearance, and facilities together with the customer, and starts a business talk for preliminary housing plan determination. However, since Meister is in a position to give technical advice using knowledge related to residential construction, it is not possible to make contracts such as discounts or to set special contract items, even though it can be added up according to the setting of specifications. Since contracts such as discounts and special contracts cannot be determined by Meister as to whether or not they can be fulfilled, restrictions are made in advance so that customers do not suffer unexpected damage.

  The restriction of negotiations is supported by restricting the function of the dedicated program PD. Since the dedicated program PD has an accumulation function related to the house specification, the price is automatically accumulated according to the floor plan or the determination of the house equipment. The accumulation function also has a discount column. However, in negotiations with Meister, the discount column displays that only the sales staff can promise the discount amount, and the function of the dedicated program PD is restricted so that input to the discount column is not possible. Thereby, the unexpected loss of the customer resulting from involvement of Meister who is an unauthorized person can be suppressed effectively.

  Meisters are also restricted from negotiating with land as merchandise. This is because land negotiations are contracts that use information representing land prices and addresses, so information on addresses corresponding to the customer's personal information is required and price negotiation is also required. The dedicated program PD has a land explanation function for explaining the land as a product by using information representing the price and address of the land.

  The land explanation function of the dedicated program PD displays the confirmation that the sales staff is in charge of dealings with the land for the land inquiry from the customer, and the inquiry from the customer is sent to the home sales server. Send to system 10. The home sales server system 10 notifies the sales staff who has jurisdiction over the area where the customer is looking for land of the inquiry content from the customer. Thereby, the information regarding the address of the new house corresponding to the customer's personal information can be protected.

  The land explanation function of the dedicated program PD has a land technique explanation function which is a technical explanation regarding matters such as land improvement and piles. The land technology explanation function is restricted for Meister, but the sales staff can release the restriction for Meister. Specifically, the sales staff can release the restriction on the land technology explanation function by transmitting the technical information about the land to a specific Meister. As a result, the Meister can give advice on technical matters regarding the land to the customer.

  FIG. 7 is a schematic diagram illustrating a communication environment between a customer and a Meister. The dedicated program PD is configured to be connected to the home sales server system 10 via the Internet 91 using the TCP / IP protocol. In communication using the TCP / IP protocol, its own IP address is always transmitted to the communication partner.

  However, since the IP address is information that can be said to be personal information of the customer, in this embodiment, the customer's IP address is protected (hidden) by being configured to communicate with the customer via the home sales server system 10. ing. Furthermore, in this embodiment, since communication is performed via the home sales server system 10, the home sales server system 10 can automatically generate a communication log between the customer and the Meister.

  Specifically, as can be seen from FIG. 7, the customer computer 31 operated by the customer establishes communication with the home sales server system 10 using the TCP / IP protocol, while the business negotiation operated by the home meister. The computer 32 establishes communication with the home sales server system 10 using the TCP / IP protocol. As a result, the dedicated program PD for the customer and the home meister communicates with the home sales server system 10 as a partner, so that the communication is performed without knowing the mutual IP address. As a result, for example, it is possible to prevent collection of IP addresses due to visitor impersonation.

  The home sales server system 10 may use another relay server 11 for the purpose of reducing the load, for example. Specifically, the home sales server system 10 can be executed simply by changing the address of the communication destination for the dedicated program PD. The relay server 11 may be configured to automatically generate a communication log. When the communication log is generated, for example, the communication log is periodically transmitted to the home sales server system 10 at predetermined time intervals. You may comprise as follows.

  In step S35, the sales staff can monitor the business negotiation between the customer and the Meister in the area in which he / she has jurisdiction. That is, the home sales server system 10 permits access to a computer for negotiation having attribute information of sales staff including the desired building acquisition location given by the customer side computer in the sales area. Thereby, the sales staff can consult with the Meister about the contract application in consideration of the operation level of the home maker and the load on the sales staff. On the other hand, if a problem is found in the business negotiation by Meister, the sales staff can point out the problem to Meister.

  In step S36, the Meister makes a contract application with the home maker after obtaining the consent of the customer. However, Meister consults in advance before obtaining customer consent. As a result, if a problem is found in the business negotiation by Meister, the sales staff can take over the correction in a state where it has been resolved before the contract application.

  The final stage plan thus completed becomes the final stage plan in the contract application to the home maker who is the operator. Since the final plan is completed with the cooperation of Meister, sales staff to home makers can proceed with the contract smoothly. Thereby, the home sales system 90 can perform a business with high customer satisfaction while remarkably reducing the burden of contract work by the sales staff.

  In this way, pre-certified Meisters can support initial business negotiations for home construction, so sales staff will provide customers with detailed business negotiations at the contract work stage. be able to. Furthermore, since the business negotiation between the customer and the Meister is performed in a state in which the personal information of the customer is kept secret, it can be disclosed on the Internet and widely used as a reference example for a third party.

  Furthermore, in the present embodiment, when a business negotiation is batten from the Meister to the sales staff, it is possible to contact each other in a state in which information is shared between the two. As a result, it is possible to change the business negotiation in a state and timing appropriate for both the sales staff and the Meister. The business negotiation between the customer and the Meister is also called a business negotiation at the first business negotiation level. The negotiation between the customer and the sales staff is also referred to as a negotiation at the second negotiation level.

  In this embodiment, since a customer can formulate a plan with the cooperation of a home building expert in an anonymous state, the customer's personal information can be disclosed to each other while being protected. Thereby, the customer can proceed with the business negotiation with reference to the business negotiations of other customers. Furthermore, the collected communication logs can be edited and published together with a built plan (FIG. 5) if the customer's permission is obtained, and can be used for business negotiations of other customers. In addition, sales staff can acquire know-how from housing meisters.

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

(1) In the home sales system 90 of the above embodiment, the Meister can perform advice and preliminary business negotiations regarding home construction. However, the role of the Meister is not limited to these matters, and may be configured to perform the following activities, for example.
(A) Meister may give advice to a person who has performed a simulation of wallpaper or cloth in a virtual house exhibition hall. The Meister is preferably the opposite sex with know-how as an interior coordinator or color coordinator.
(B) Meister can cause an earthquake (for example, shake the background) at an appropriate timing in the virtual space. In an earthquake, old buildings and monuments collapse, making it easy to talk about the earthquake resistance of houses.
(C) Meister can cause anomalies such as power outages, fires, and the passage of tornadoes at appropriate timing in the virtual space. During a power outage, many buildings are dark, but only some are bright. Some buildings are specific houses that are supplied with electricity from household storage batteries or garage hybrid vehicles. In the case of a fire, some buildings (the buildings where fire resistance measures were taken for certain houses) remain unburned while the surroundings are completely burned out. In passing the tornado, the tiles of the building on the route are blown off, while some buildings (the specific houses are tiled buildings with strong wind countermeasures) remain intact.
