Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for electronic commerce on the Internet, and more particularly, to a single or a plurality of systems utilizing a CAD-virtual reality system operated on an Internet communication network. Workers make joint design and distributed presentations, and in accordance with the results of the joint design and distributed presentations, proceed with transactions related to architecture, interior, furniture, various materials, construction, sales, etc. in an auction system. The present invention relates to an e-commerce method, an e-commerce method and a system using a CAD-virtual reality system.

[0002]

2. Description of the Related Art Conventionally, in the fields related to architecture, civil engineering, and interior design, designers design objects manually or carry out design using a CAD program of a computer, based on the design drawings. Materials and physical quantities are determined, transactions are made for delivery of the materials and physical quantities, and construction is proceeded by making decisions by the installer.

However, according to such a conventional design and construction method, many stages of work processes are required from design to construction, so that cost and time are required. In addition, since the processing areas of the tasks in each field are sorted and advanced, it was difficult to smoothly cooperate and correct the tasks.

[0004] On the other hand, recently, various architectures, online design services in the fields related to civil engineering or interiors, and delivery services of materials and materials and services of contractors have been becoming commonplace through the Internet communication network. The services provided through the Internet communication network are provided with a vast library of design-related services, and various transaction services are performed quickly. Therefore, there is an advantage that not only the cost is reduced but also the design and construction time is shortened.

Further, in services related to construction, design, civil engineering and construction through the Internet communication network, construction and design requests can be advanced in an auction system through an Internet auction site. In addition, services for construction and delivery of materials can be performed by auction and purchase.

[0006]

By the way, in the conventional services for construction, design, civil engineering, and construction related to the above, the seller arbitrarily applies his / her own standard and requests the construction and design of the product or the construction. And formulate prices for material delivery.
For this reason, it has been impossible for the seller and the buyer to set an appropriate level of price. Also, since only one method of auctioning is possible for one product, fair price formation tends to be hampered.

[0007] In addition, only through one-sided photo image information or text through Internet web services related to the conventional architecture, design, civil engineering, and construction,
Since it was possible to explain the product, the presentation on the product could not be made sufficiently on the Internet. In addition, products that have not been standardized had to be directly manufactured from the user side.

[0008] Further, when attempting to describe such a product in a three-dimensional manner, a user of the service directly pays additional cost and effort to make up a predetermined portion or the entirety required for composing the product. The parts had to be produced and configured as three-dimensional product presentation information.

Furthermore, even if the presentation information of the product is completed using the three-dimensional virtual reality, it is impossible to freely move the item of the building or the civil engineering work and to deform the information of the product. However, even in the case of three-dimensional data created using a CAD program, it was not possible to confirm accurate numerical values for each field of the product. Furthermore, since it can be realized only by one method in virtual reality or CAD, it is not easy to create presentation information required for trading of goods.

On the other hand, in order for a user to create a virtual reality program or a CAD program by operating it on the Internet web, a dedicated browser program or a separate plug-in (pl.
ug-in) The program had to be downloaded and used from the service provider's website.

Even if such a dedicated browser program or a separate plug-in program is used, only one user can operate a virtual reality or CAD program for one project. It took a long time to get the result. In addition, the exchange of business opinions and technical exchanges between the project owners was not smooth.

[0012] Further, in the case of services provided on the Internet web, transactions are performed only in a state where the design of a predetermined building or civil engineering work has been performed and the shape and function of the product have been completely determined. In the case of sellers, expensive design and presentation work had to be performed over a long period of time. Here, since the exchange of opinions between the buyer and the seller is unilaterally conducted until the time when the transaction is concluded, the information exchange is not performed smoothly, It was difficult to form a fair price because the possibility was low.

On the other hand, in order to exchange opinions between the buyer and the seller in order to conclude a transaction, text or image chatting is performed using other chatting services built on the Internet web. It was necessary to exchange opinions through a meeting, or to have the buyer and seller meet face-to-face to confirm the product and exchange opinions.

[0014]

In S6000), for example, a house ordered from a customer and a property presented by a supplier (eg, an apartment, an office tel,
Joint design and virtual reality simulation for the sale service of shopping mall buildings, commercial buildings, etc.)
Automatically determine the appropriate consumer supply price and have multiple installer members auction based on the consumer supply price.
This ensures that transactions are performed at a fair price.

Further, in the joint design and presentation process using the 3D CAD and virtual reality system (step S7000), the 3D CAD and the virtual reality system are connected to a website (WS) of an Internet service server (ISV) through an Internet communication network. Operate the CAD and virtual reality system online on a remote control basis for joint design and distributed presentation.

On the other hand, a process of joint design, presentation, and transaction in the interior field according to the step S3000 will be described in detail with reference to flowcharts of FIGS.

First, a single personal computer terminal (COM1) or a plurality of computer terminals operated by a plurality of personal members are used to execute a three-dimensional CAD and virtual reality engine (ENG) online through an Internet communication network. When the operation is started (Step S3010), the interior database management system 44 of the Internet service server (ISV) uses the computer terminal for the individual member to execute the 3D CAD and virtual reality engine (EN).
It is determined whether a new input using G) is performed (step S3020).

As a result of the above determination, when it is determined that a new input is to be performed, the interior database management system 44 of the Internet service server (ISV) performs a single user mode with a single individual member or a plurality of individual members. One of the multi-user modes that can be co-designed in real time by using a computer terminal of this type, so that a new CAD drawing in the interior or exterior field can be entered, and a three-dimensional virtual reality design can be performed. (Step S3030).

Next, the interior database management system 44 modifies the three-dimensional CAD and the CAD drawing created by operating the virtual reality engine (ENG) according to the single-user mode or the multi-user mode, An operation of changing the virtual reality design data is performed, and a presentation is performed on the CAD diagram and the virtual reality design data in real time (step S3040).

By the way, in the step S3020,
If the interior database management system 44 determines that the input is not a new entry, the interior database management system 44
Accessing data stored in the diagram / model storage area 38 of the information database (DB2) through S), searching for CAD drawings and virtual reality design data created by individual members, or building, designing member companies, The construction member, such as an interior member company, searches for CAD drawings and virtual reality design data created for the individual member as a service provider (step S3050).

The Internet Business Server (ISV)
The interior database management system 44 searches the data stored in the information database (DB2) to determine whether the CAD and the virtual reality design data desired by the individual member exist (step S306).
0), if it is determined that the desired data does not exist,
Proceeding to S3030, input of a new CAD diagram and virtual reality design can be performed.

If it is determined that the data desired by the individual member exists, the interior database management system 44 proceeds to step S3040 and stores the data in the figure / model storage area 38 of the information database (DB2). After arbitrarily correcting the CAD data and the virtual reality design data, the virtual reality design can be changed or a presentation can be made in real time.

Next, the interior database management system 44 converts the newly created CAD drawing and virtual reality design data or the CAD drawing and virtual reality design data obtained by arbitrarily modifying and changing already created data into an information database ( It is determined whether it should be stored in DB2) (step S3070).

As a result of the above judgment, the work data is stored in the information database (D) by the personal member computer terminal (COM1).
If it is determined that the operation for storing in B2) is performed, the corresponding CAD drawing and the virtual reality design data are stored (step S3080).

If it is determined that the operation for storing the work data in the information database (DB2) has not been performed, it is determined whether the corresponding CAD drawing and the virtual reality design data should be deleted (step S3090).

As a result of the above determination, if it is determined that the operation for deleting the CAD drawing and the virtual reality design data is performed on the personal member computer terminal (COM1), the interior database management system 44
The operation data is deleted from the Internet, and the process returns to step 3020.

On the other hand, after the step S3080, the interior database management system 44 operates an automatic estimation and indexing system (EV) to automatically execute the CAD drawing and the virtual reality design data presented in real time.

At this time, the interior database management system 44 determines whether the estimated price or the price presented by the individual member is a reasonable amount (step S3110).

As a result of the above determination, if it is determined that the estimated price indexed through the automatic estimation indexing system or the price presented by the individual member is not a reasonable amount, the interior database management system 44 proceeds to the step S3.
Proceeding to 040 again, the CAD drawing is modified in accordance with the estimated price or the price presented by the individual member to change the virtual reality design data, and then a real-time presentation is performed.

If it is determined in the step S3110 that the estimated price or the price presented by the individual member is a reasonable amount, the estimated price or the price information presented by the individual member is compared with the CAD information and the virtual information. The actual presentation information is displayed on the bulletin board of the auction content (step S3120), and the deadline time and price limit line of the auction are presented (step S3130).

Next, the interior database management system 44 allows a plurality of installer members to connect to a website (WS) through a computer terminal, and competes for a construction estimate by referring to the estimated price displayed on the auction bulletin board. Match (step S3140).

In the interior database management system 44, the result of the bidding estimate involving a plurality of installer members determines whether or not the individual member requesting the interior or exterior product transaction has achieved the desired construction estimate. Is determined (step 3150).

As a result of the above determination, when the interior database management system 44 determines that the construction estimate desired by the individual member has not been formed, the interior database management system 44 determines whether to extend the deadline for auction or modify the price limit line. An inquiry is made to the individual member (step S3160).

If it is determined that the individual member desires to extend the auction closing time or modify the price limit line, the process returns to step S3130 to reset the deadline time limit and the price limit line again. Adjust and present.

On the other hand, if it is determined in step S3150 that the construction estimate desired by the individual member has been formed, the interior database management system 44
In order to agree on the mutual requirements between the computer terminal for the contractor member and the computer terminal for the individual member who have won the construction quotation according to the auction through the chatting service of the corresponding website (WS) or voice. Then, a meeting by chatting is advanced (step S3170).

Thereafter, the interior database management system 44 pays the price for the utility or product between the individual member and the installer member in the interior or exterior field and the price for providing various services. Thereafter (step S3180), the user can return to the member content area of the website (WS) (step S1040).

Next, referring to the flow charts of FIG. 8 and FIG. 9, the joint design, presentation, and transaction process in the field of building materials according to the present invention will be described in detail.

If it is determined that the operation for storing in 2) has not been performed, the building material database management system 46 determines whether or not the corresponding CAD drawing and virtual reality design data should be deleted (step S4090). If it is determined that the operation for deleting the CAD drawing and the virtual reality design data is performed on the personal member computer terminal (COM1), the corresponding work data is deleted on the Internet, and the process proceeds to step 4020 again.

On the other hand, after the step S4080, the building material database management system 46 operates the automatic estimation indexing system (EV) to automatically perform the CAD drawing and the virtual reality design data presented in real time. Then, an estimated price is calculated, and the individual member is required to input a price not to be presented (step S4100).

At this time, the building material database management system 46 determines whether the estimated price or the price presented by the individual member is a reasonable amount (step).
S4110).

As a result of the above determination, if it is determined that the estimated price determined through the automatic estimation indexing system or the price presented by the individual member is not a reasonable amount, the building material database management system 46 proceeds to the step S40.
Proceeding to 40 again, the CAD drawing is modified according to the estimated price or the price presented by the individual member, and the virtual reality design data is changed, so that the real-time presentation is performed.

By the way, if it is judged in the step S4110 that the estimated price or the price presented by the individual member is a reasonable amount, the combination of various building materials and furniture and the estimated price of custom-made furniture and custom-made materials are considered. Alternatively, the price information presented by the individual member, the CAD drawing and the virtual reality presentation information are displayed on the bulletin board of the auction content (step S4120), and the deadline time and the price limit line for the auction method are presented (step S4).

Next, the virtual model house database management system 50 converts the newly created CAD drawing and virtual reality design data, or the CAD drawing and virtual reality design data obtained by arbitrarily modifying and changing already created data. It is determined whether to store the information in the information database (DB2) (step S6070).

As a result of the above determination, the work data is stored in the information database (D) by the personal member computer terminal (COM1).
If it is determined that the operation for storing the data in B2) is performed, the corresponding CAD drawing and the virtual reality design data are stored in the information database (DB2) (step S6080).

On the other hand, if it is determined that the operation for storing the work data in the information database (DB2) is not performed on the personal member computer terminal, the virtual model house database management system 50 proceeds to the corresponding CAD diagram. Then, it is determined whether the virtual reality design data should be deleted (step S6090).

As a result of the above determination, when it is determined that the operation for deleting the CAD drawing and the virtual reality design data is performed on the personal member computer terminal (COM1), the virtual model house database management system 5
0 deletes the relevant work data from the Internet,
The process proceeds to step S6020 again.

On the other hand, after performing the process of step S6080, the virtual model house database management system 50 operates the automatic estimation indexing system (EV) to execute the virtual model having the presentation in real time. An estimate of the consumer supply price of the house is automatically determined (step S6100), and it is determined whether the estimated price is an appropriate amount (step S6110).

As a result of the above determination, if it is determined that the estimated price as the consumer supply price determined through the automatic estimation and determination system is not an appropriate amount, the virtual model house database management system 50 proceeds to the step. S
Proceeding to 6040 again, the CAD drawing relating to the virtual model house is modified according to the estimated price so that the virtual reality design data can be changed, and then the presentation is made in real time.

When the estimated price is found to be an amount appropriate for the supply price of the model house to the consumer according to the result of the determination in step S6110, the virtual model house database management system 50 sets the Estimated prices of virtual model houses, such as custom-built dwellings, shopping malls, and commercial buildings, whose mechanism and materials can be changed as required, and CAD diagrams created to sell the virtual model houses Then, the virtual reality presentation information is posted on the bulletin board of the sale content (step S6120).

At the same time, the virtual model house database management system 50 provides, for example, an estimated price for a virtual model house unilaterally presented by a supplier such as a general house, an apartment, a shopping street, a commercial building, and the like. The CAD drawing and the virtual reality presentation information relating to the virtual model house are posted on the bulletin board of the content for sale (step S6125), and the deadline for the distribution of the customer-ordered virtual model house and the virtual model house for presenting the supplier are set. Present the price limit line (stage
S6130).

In such a state, the virtual model house database management system 50 performs distributed presentations through CAD drawing data and virtual reality design data created by a plurality of installer members for the corresponding virtual model house, Competition for sale is carried out in such a manner that the request from the member and the opinion about the features of the installer are posted on the bulletin board (step S6140).

On the other hand, the virtual model house database management system 50 determines whether or not the proper sale situation desired by the individual member who sells the virtual model house is satisfied, as a result of competition for sale by a plurality of construction members. Is determined (step S6150).

As a result of the above determination, if it is determined that the proper sale situation desired by the individual member has not been established, the virtual model house database management system 50 determines whether the individual member can extend the deadline time for the sale service, Inquires whether the user wants to modify the price limit line (step S6)
160).

As a result of the above determination, if it is determined that the individual member wants to extend the deadline time or modify the price limit line for the sale service, the virtual model house database management system 50 returns to step S6130 again. Go ahead and extend the deadline or modify the price line to present it.

On the other hand, if it is determined in step S6150 that the proper distribution situation desired by the individual member has been established, the virtual model house database management system 50 is established on the corresponding website (WS). Using the character or voice chatting service, the individual member and the installer member are required to hold a chatting meeting regarding the mutual requirements (step S6170), and the contract is awarded according to the virtual model house sales service. The price is paid (step S618).
0).

Next, the virtual model house database management system 50 of the Internet service server (ISV) enables the individual member computer terminal to return to the member content menu again (step).
S1040).

Next, the joint design and presentation process using the three-dimensional CAD and virtual reality system according to the present invention will be described in detail with reference to the flowcharts of FIGS.

First, the Internet business server (IS
V) is a single user mode in which a single individual member designs a three-dimensional CAD diagram and virtual reality online through a computer terminal, or a plurality of individual members operate each computer terminal to co-design and distribute. It is determined whether or not the user is in a multi-user mode for performing a presentation operation (step S7000).

As a result of the above determination, if it is determined that the operation mode is the single user mode, the Internet service server (ISV) executes the three-dimensional CAD and the virtual reality engine (ENG).
Is operated (step S7100), and it is determined whether the single personal member computer terminal inputs a new CAD diagram and performs virtual reality design (step S7110).

As a result of the above determination, if it is determined that the input of a new CAD diagram and the design of a virtual reality are to be performed by the single personal member computer terminal, the Internet service server (ISV) executes the processing of the three-dimensional CAD virtual reality engine. (ENG) to enable CAD drawing input and virtual reality design in various fields such as architecture, civil engineering, interior, machinery, and heavy industry construction (step S712).
0).

Next, the Internet service server (ISV) modifies the newly created CAD drawing and changes the design relating to the virtual reality data, and gives a real-time presentation using the CAD drawing and the virtual reality design data ( Step S7130).

On the other hand, if it is determined in step S7110 that no new entry is made, the CAD / virtual and virtual maps created by the single individual member are stored in the diagram / model storage area 38 of the information database (DB2). Retrieve the real design data or other CAD drawings and virtual reality design data created for the installer member (step S714)
0).

At this time, the Internet service server (ISV) determines whether there is a CAD drawing and virtual reality design data desired by the individual member (step S).
7150). If it is determined that there is no desired existing work data, the process proceeds to step S7120 to design a new CAD drawing and virtual reality. If it is determined that existing work data desired by the individual member exists, the step S7130 is performed.
Then, the CAD drawing and the virtual reality design data stored in the drawing / model storage area 38 of the information database (DB2) can be corrected and the design can be changed.

After the step S7130, the Internet service server (ISV) determines whether to store the worked CAD drawing and virtual reality design data in the information database (DB2) by using a single personal computer terminal. (Step S7160).

As a result, if the individual member computer terminal determines that it does not want to store work data in the information database (DB2), the Internet service server (ISV) should delete the work data. Inquiry is made (step S7170), and a deletion process is performed.

[0189] On the other hand, if it is determined that the single individual member desires to store work data in the information database (DB2), the Internet service server (ISV) sets the corresponding CAD drawing and virtual reality design. Store the data in the information database (DB2) (Step S7)
180).

Next, the Internet service server (ISV) is a multi-purpose system for co-designing CAD diagrams and virtual reality designs with other individual member computer terminals separately from the single individual member computer terminal. Determine if user mode is in progress (step
S7190).

As a result of the above determination, when it is determined that the multi-user mode is not advanced, the Internet service server (ISV) performs the input of the CAD drawing and the virtual reality design function through the three-dimensional CAD virtual reality engine (ENG). It is determined whether a single personal member computer terminal has been terminated.

If it is determined in step S7195 that the input of the CAD drawing and the virtual reality design function have been completed, the single personal member computer terminal returns to the member content menu of the website (WS). (Step S1040).

On the other hand, in the step S 7050 or the step S 7190, it is assumed that the multi-user mode in which a plurality of personal member computer terminals participate in the CAD drawing input and the virtual reality design of the same project jointly is applied. If it is determined, the Internet service server (ISV) enables the three-dimensional CAD virtual reality engine (ENG) to be simultaneously performed on a plurality of personal member computer terminals according to the multi-user mode (step S7200).

The Internet service server (ISV) enables each individual member to search for a mutual member user number (ID) on a website (WS) in order to enable collaborative work (steps). S7200),
A predetermined individual member searches a plurality of work rooms set up in the web site (WS) to find a work room of another individual member to be jointly designed (S7220). . In addition, an arbitrary work room in which a predetermined individual member operates a computer terminal and works with a plurality of individual members can be set up on the website (WS) (step S7230).

In step S7210, the user number (ID) of another individual member working together with the predetermined individual member is found, or in step S7220 the other individual member working together with the predetermined individual member is determined. Upon finding the work room established by the individual member, the Internet service server (ISV) allows the computer terminal for the individual member participating in the joint work to operate the three-dimensional CAD virtual reality engine (ENG) (step S7240). .

Then, the Internet service server (ISV) operates a three-dimensional CAD virtual reality engine (ENG) according to the multi-user mode to enable a new CAD drawing and a virtual reality design through a joint operation (step S7250). ), Modify the design and change the design of the newly created CAD drawing and virtual reality design data, and give a presentation in real time based on the work data (step S7260).

At this time, that is, while the plurality of individual members are working together on the CAD drawing and the virtual reality design, the character or voice chatting system constructed on the website (WS) is used. Can exchange ideas with each other, and work can be carried out quickly and smoothly.

On the other hand, in step S7230, when a predetermined individual member establishes a working room on the website (WS) for collaborating with other individual members, the Internet service server (ISV) An individual member or another individual member who opened the work room is provided with an information database (DB2) through a database server (DBS).
The work data stored in the private data storage space or the common storage space constructed in the diagram / model storage area 38 of FIG.

Then, the Internet service server (ISV) determines whether there is a CAD drawing and virtual reality design data required for the individual member to work together (step S7280).

If it is determined that the work data desired by the individual member does not exist, the Internet service server (ISV) defines a new input process (step S7290), and proceeds to step S7250. Then, input of a new CAD diagram and virtual reality design according to the multi-user mode are performed.

On the other hand, if it is determined that the work data desired by the individual member exists, the Internet service server (ISV) proceeds to the process of step S7260, where the CAD diagram and the virtual data extracted from the information database (DB2) are displayed. A plurality of personal member computer terminals are used to modify the figures and change the design of the real design data so that a real-time presentation based on the CAD drawing and the virtual reality design data can be performed.

After the step S7260, the Internet service server (ISV) determines whether to store the CAD drawing and the virtual reality design data by the multi-user mode joint work in the information database (DB2) (step S7310). .

As a result of the above determination, if the plurality of individual members determine that they do not want to store the CAD drawing and the virtual reality design data, the Internet service server (ISV) determines whether the corresponding work data should be deleted. Then, if it is determined that it should be deleted (step S7320), the process proceeds to the new input process of step S7290.

On the other hand, if it is determined in step S7310 that the CAD drawing and the virtual reality design data by the joint work should be stored in the information database (DB2), the Internet service server (ISV)
Stores the corresponding work data in the information database (DB2) (step S7330).

Next, the Internet service server (ISV) determines whether the plurality of individual members have completed the joint design process in the multi-user mode (step S7340). When it is determined that the multi-user mode is to be ended, the Internet business server (IS
V) enables each individual member computer terminal to return to the member content menu of the website (WS) (step S1040).

As described above, according to the above-described embodiment, one or a plurality of members can make one or a plurality of CAD diagrams and a virtual reality design and make a presentation using character chatting or voice chatting. The exchange enables smooth collaboration. In addition, since an unspecified number of members can view the work status in real time, based on this, a product embodied through a CAD diagram and virtual reality design can be traded with a plurality of members by auction and purchase method. , Can be sold.
