The present invention relates to building or remodeling a building, and more particularly to a building specification determining method for determining a building specification between a customer and a contractor.

In recent years, with the development of CAD technology and simulation technology, a system is known in which a contractor creates a 3D image of a building and a customer confirms it on a display. Regarding this, in order for the customer to visually confirm the building, at the time of the meeting with the contractor, the contractor must confirm the image presented at the office etc. on the display, and to determine the specifications of the building. It took time and effort, and sometimes it became a trouble due to the difference in the appearance of the image from the actual building.

In this regard, a schematic design drawing, etc. can be obtained by searching the external appearance design and internal layout of the house desired by the user based on desired conditions or from the options presented by the server via the Internet or the like, Steps 1 to 8 of presenting the service contents, flow, cost, etc. for a fee in case of a fee, and presenting a concrete design drawing etc. for a fee from the options presented by the server based on the desired conditions to the desired user , A method of building a house on the Internet or the like, which includes steps 9 to 14 of ordering, instructing construction, and supporting building is known (see Patent Document 1).

However, with this technology, the user can see the schematic design drawing, etc. via the Internet, but the risk of troubles increases due to the difference between the actual building and the image that the user can see. It was thought to do.

In addition, the computer 1 on the builder side and the computer 2 on the client side can be bidirectionally communicated via the Internet line 3, and both computers can use common software for floor plan design of buildings and common data such as fittings, interior equipment, and fixtures. The floor plan design software section A, its data section AD, the floor plan design software J, and its data section JD are retained, and the builder side computer 1 is made to generate a three-dimensional visual image of the appearance/inside view. A technique is known in which a presentation material preparation section B, a mortgage trial calculation software section C, a specification preparation software section D, and an estimate preparation software section E are retained (see Patent Document 2).

However, in this technique, the computer 1 on the builder side and the computer 2 on the client side must have common software, which may increase the cost of the system and the work required for preparation. Moreover, in such a case, it is necessary to provide the software to the owner, which may cause a problem of software security.

A movable image providing step in which the contractor provides the customer with the movable image created in the movable image creating step;
A specification confirmation information receiving step of receiving specification confirmation information including the request for correction of the building specification from the customer or the approval information on the contractor side,
The method for determining a building specification is characterized by having:

That is, in the present invention, on the contractor side such as a building company or an architect office, model data is created in a form that reflects predetermined building specifications. Then, a movable image is further created based on this model data. This movable image is an image that can be moved by applying a predetermined operation. Here, moving the image may be, for example, control for changing the image as if moving inside the building. Then, in the present invention, this movable image is provided to the customer so that the customer can confirm the building specifications. Thereby, the customer can operate the provided movable image to move the image so as to move to each place of the building and confirm the specifications at each place with a sense of a game, for example.

The customer then requests or approves the specifications displayed on the provided movable image. Then, when the customer requests a modification of the specifications, the contractor executes the model data creation process, the movable image creation process, and the movable image provision process again to generate a new possible image with the modified building specifications. Provide to customers. Then, these steps are repeatedly executed until the customer approves the building specification displayed on the movable image.

This allows the customer to check the building specifications at any time and place he/she enjoys until he is satisfied. As a result, it is possible to improve efficiency in terms of time and man-hours until the determination of building specifications and reduce costs. Moreover, since the customer can confirm the building specifications in a state closer to actual use, it is possible to suppress the occurrence of troubles due to the difference in recognition of the building specifications between the customer side and the contractor side.

Further, in the present invention, in the moving image creating step, the moving image is created by applying the model data created in the model data creating step to a moving image creating means that is a game engine program. You can Here, by using a so-called game engine program as the moving image creating means, it is possible to create a clearer and higher quality moving image more easily. Further, the moving image can be moved in a more advanced manner.

Further, in the present invention, the predetermined building specification may be a customer desired specification including a specification desired by the customer provided in advance by the customer. According to this, first, it is possible to convey the desired specifications from the customer to the contractor, and to provide the customer with a movable image that reflects the desired specifications from the beginning.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the following embodiment is one mode of the present invention and does not limit the technical scope of the present invention.

<Example 1>
FIG. 1 shows a flow of a method for determining building specifications in this embodiment. In this flow, first, in step S1, for example, a customer who is the owner of a building makes a design request to a contractor such as a construction company or a building office. In this embodiment, this design request can be made via the WEB site or SNS (it is also possible to request the design by telephone or e-mail, of course). The contractor accepts the request in step S3. Next, the contractor lends the mobile terminal to the customer if necessary in the process of step S5. The mobile terminal may be a so-called tablet terminal or a smartphone. The process of step S5 corresponds to the terminal providing process in this embodiment. Further, in step S7, the customer notifies the desired specifications of the building. This desired specification may be notified using the mobile terminal rented out in step S5. Further, it may be performed at the same time when the design request is made in step S1. This desired specification corresponds to the customer desired specification in this embodiment.

Then, in step S9, the contractor creates an application (hereinafter, also simply referred to as an application) incorporating the desired specifications contacted by the customer in step S7. This application is an application created using so-called game engine software, and as functions, (a) the structure of the building, the design of the wall surface/floor surface, and the equipment are reproduced. (B) It is possible to move by walking through the outside and inside of the building, or by selecting a destination. (C) In each place (each room) of the building, it is possible to visually confirm by changing the design of the wall surface/floor surface and the equipment. In addition, (d) a building may have a simple game function as a stage. The process of step S9 corresponds to the model data creating process and the movable image creating process in this embodiment.

The application created in step S9 is sent to the customer. This application may be sent by attaching it to an e-mail, or by uploading it to an online data storage and sending the URL and password by e-mail. Depending on the terminal of the customer, a method of mailing an optical disk or the like storing the application may be used. This step corresponds to the movable image providing step in this embodiment. Next, in step S11, the customer downloads and executes the application, and the specifications of the building in the application are confirmed.

If the customer wishes to change the specifications of the building in the application, the customer requests the contractor to correct the specifications. In practice, the application whose specifications have been changed during execution of the application may be saved and returned, or only the changed portion may be notified using communication means such as email or line. This step corresponds to the specification confirmation information receiving step in this embodiment. Then, when the customer requests a specification correction, the contractor corrects the application data in step S13, the corrected application is sent to the customer again, and the application is downloaded and downloaded again by the customer in step S11. It is executed and the specification of the building in the application is confirmed. Here, the process of step S11 and the process of step S13 are repeatedly performed until the customer approves the specification displayed in the application in step S11.

Then, when the customer approves the building specification in the application confirmation in step S11, the contractor is notified of that fact, and in step S15, the contractor confirms the content of the building specification in the approved application. Next, in step S17, an estimate is created based on the approved building specifications, and the customer is notified.

As described above, in the flow of determining the building specifications in the present embodiment, the customer does not need to meet directly with the contractor to have a meeting, and basically it is possible to determine the building specifications only by exchanging data. is there. Therefore, it is possible to reduce the time and cost costs for determining the building specifications. Further, the customer can sufficiently reflect the contents that are difficult to convey to the contractor in the specification. Furthermore, in the present embodiment, the building specifications are confirmed by the customer downloading and executing the application created using the game engine program. Therefore, the customer can move inside the simulated building exactly like a game and confirm the specifications of the wall surface, the floor surface, the door, and the equipment in addition to the floor plan. As a result, the contractor does not need a facility such as an exhibition hall (model house), and it is possible to save the labor and cost of the preview. Further, in this embodiment, the contractor rents the mobile terminal to the customer as necessary, so that even a customer who does not have an internet environment can easily check the specifications by the application.

FIG. 3 is a diagram for explaining the processing of the information related to the building specifications of the present embodiment in more detail. As shown in the figure, in this embodiment, first, in step S100, the contractor creates model data of a building that reflects the building specifications at that time. This model data is created using, for example, 3D graphics software (represented by, for example, a blender). Further, the data such as the pattern of the wall or floor may be further created by using image processing software (PHOTOSHOP (registered trademark), illustrator (registered trademark) or the like may be used). The process of step S100 corresponds to the model data creating process in this embodiment.

Next, in step S101, the contractor develops an application capable of displaying and operating a 3D image of a building by using the game engine software as described above. This game engine software may be stored in the server 5 described above, but may be stored in another computer. Game engine software (for example, UNREAL ENGINE (registered trademark), U
It is also possible to use "nyty", CryENGINE (registered trademark), or the like. ) Creates an application program that allows a customer to move a 3D image of a building like a game. The process of step S101 corresponds to the movable image creating process in this embodiment. Further, in FIG. 3, the application creating tool 10 refers to a tool combining 3D graphics software, image processing software, and game engine software, and the game engine software corresponds to a movable image creating means. Further, it can be said that step S9 in FIG. 1 corresponds to a combined step of step S100 and step S101 in FIG.

Then, as shown in FIG. 3, the created application is uploaded to the online data storage 20 in step S103. The file format at that time may be, for example, an APK file. The online data storage 20 may be, for example, Google Drive or Dropbox (registered trademark). Then, in step S105, the application data is stored and managed in the online data storage 20. Then, in step S107, the shared URL and the password for accessing the online data storage 20 are transmitted from the online data storage 20 to the tablet terminal 30 owned by the customer or lent to the customer by e-mail. .. In FIG. 3, steps S103, S105, and S107 correspond to the movable image providing step in this embodiment.

In the tablet terminal 30, the customer receives the mail in step S109, accesses the online data storage 20, and installs the application. Further, in step S113, the customer activates and operates the application to confirm the content of the building specifications. When the customer confirms the building specifications and determines that the specifications need to be corrected, in step S115 information such as corrections/requests is transmitted to the contractor. The step S115 corresponds to the specification confirmation information receiving step in this embodiment. On the contractor side, in step S117, the data related to the building specification is corrected.

After that, returning to step S100, the model data is created again, and in step S101, the application is created again using the game engine software. Then, in step S121, the updated application file is uploaded to the online data storage 20, and in step S123, the shared URL and password for accessing the online data storage 20 are transmitted again by e-mail. Then, in step S113, when the customer activates the application and confirms the content of the building specification, the flow of the flow is continued until the building specification need not be corrected and the customer approves the building specification.
