mon GO의 등장은 가상현실이 현실로 다가오게 만드는 계기를 마련하였다. 일반적으로 가상현실은 가상으로 현실을 대체하거나 보완할 수 있는 모든 기술을 의미하지만, 기술의 발달과 함께 Virtual Reality(VR), Augmented Reality(AR), Mixed Reality(MR)과 같은 다양한 하위 분류가 만들어졌다. VR은 일반적으로 인식하는 가상현실을 보여준다. 컴퓨터로 구현한, 현실과 구분되는 가상의 세계를 의미하며 VR을 이용하는 일반적인 방법은 Head mounted display(HMD)를 이용하여 현실의 시야를 완전히 차단하고 가상의 공격을 보여주는 형태로 이용된다. 반면, AR은 현실 속에 가상의 정보를 증강시켜 보여주는 형태를 의미한다. 따라서 현실과 가상의 경계가 명확하고, 모든 가상요소는 현실세계 위에 단순히 덧보여지는 요소에 불과하다. 따라서 대부분의 AR 콘텐츠는 스마트 디바이스의 카메라를 이용하여 현실 요소를 촬영하고 그 위에 소프트웨어로 구현된 콘텐츠를 추가하여 보여주는 방법을 이용한다. 마지막으로 MR은 현실에 가상의 요소를 혼합하여 보여주는 기술이다. 현실에 가상 콘텐츠를 추가하여 보여주는 것은 AR과 비슷한 개념이지만 MR은 현실과 가상 콘텐츠를 구분할 수 없을 정도의 상호작용이 동시에 이루어진다. 따라서 MR을 이용할 경우 현실과 가상의 구분이 어려워지기 때문에 현실세계를 새로운 공간으로 재창조할 수 있다. 이러한 가상현실화 기술은 단순히 현실세계 위에 가상요소를 추가하는 개념이 아닌 현실세계와 가상세계를 동시에 활용하여 인간이 영위할 수 있는 세계를 한 차원 더 높일 수 있는 기술로 볼 수 있다. 이러한 가상현실화 기술은 아직 실생활에서까지 이용하기에는 어려운 단계이지만 현재 꾸준히 연구가 진행되고 있으며, 지속적으로 성장을 이어오고 있다.Virtual reality is a technology that implements an artificial environment or world similar to reality using a computer. This virtual reality technology is commonly recognized as a technology called VR. In the past, virtual reality was treated as a technology to operate the virtual world by inputting the human mind into the virtual world, but in 2016, Pok

The advent of mon GO provided an opportunity for virtual reality to come closer to reality. In general, virtual reality refers to any technology that can replace or supplement reality with virtual reality, but with the development of technology, various subclasses such as Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) have been created. lost. VR shows what we usually perceive as virtual reality. It means a virtual world that is implemented by a computer and is distinguished from reality. A common way to use VR is to completely block the view of reality using a head mounted display (HMD) and show a virtual attack. On the other hand, AR means a form of augmenting and showing virtual information in reality. Therefore, the boundary between reality and virtuality is clear, and all virtual elements are simply elements that are added to the real world. Therefore, most AR contents use a method of photographing reality elements using a camera of a smart device and adding software-implemented contents thereon. Finally, MR is a technology that blends virtual elements into reality. Adding and showing virtual content in reality is a similar concept to AR, but MR interacts at the same time to the extent that real and virtual content are indistinguishable. Therefore, when using MR, it becomes difficult to distinguish between reality and virtual reality, so the real world can be recreated as a new space. This virtualization technology is not a concept of simply adding virtual elements on top of the real world, but can be seen as a technology that can enhance the world that humans can lead by using both the real world and the virtual world at the same time. Although this virtualization technology is still at a difficult stage to be used in real life, research is currently being conducted steadily and continues to grow.

On the other hand, metaverse is a term created by combining Meta, which means transcendence, and Verse, which means the universe and world. Metaverse means the space of the virtual world that transcends the real world, as the etymology suggests, and a specific and standardized definition has not yet been presented. The name of this metaverse has recently been illuminated and widely used. However, the concept of the metaverse is a concept that has already become familiar through various online games, VR, AR, and MR contents based on the existing virtual world. Therefore, the various movements of the metaverse environment that have recently been highlighted can be seen as efforts to lead the connection between the virtual world and the real world, which was previously presented only abstractly, into a more specific and clear concept. The characteristic of this metaverse is that real actions can be performed continuously in the virtual world connected to the real world. Recently, contents such as online meetings, online concerts, and online festivals that use the metaverse are appearing in various fields by utilizing these characteristics. Contents utilizing the metaverse are not affected by the access location, and users interacting on the metaverse have the advantage of not physically affecting each other. Therefore, in recent years, rather than simply using the metaverse for the purpose of providing virtual services, non-face-to-face/online services themselves have been implemented as a metaverse to provide face-to-face activities that are not affected by time and place. It is showing a movement to provide face-to-face service.

Meanwhile, due to the recent global infectious disease pandemic, various types of services are changing to forms that utilize online/non-face-to-face technology. In particular, these non-face-to-face/online technologies were not only used as a way to respond to the pandemic situation of infectious diseases, but provided an opportunity to quickly introduce technologies expected to be applied to future society, such as telecommuting and video lectures. Global non-face-to-face/online has brought about changes in various fields. It has accelerated the introduction of non-face-to-face/online services such as telecommuting and online education, and has dramatically improved the network and computing technologies that are the foundation of non-face-to-face/online technologies. In particular, since most non-face-to-face technologies are procured and operated based on cloud services, the demand for cloud and virtualization technologies has increased rapidly, and at the same time, the demand for high-performance servers has also increased for stable service provision and use. From the user's point of view, smart devices such as PCs, smartphones, and tablets are essential to use non-face-to-face services, so smart devices are rapidly disseminated, and demand for products using high-performance semiconductor technology is increasing for stable service use. increased. In this way, the current earth is undergoing unprecedentedly rapid digitalization, and a new environment utilizing this is gradually required.

The main purpose of early non-face-to-face services was to transmit data in one or both directions. A typical example is a chatting/messenger service that can transmit simple text, voice, and video through a network, or a streaming service that can provide complete video and audio in one direction. However, over time, there was a need for a method that can be used and utilized in a non-face-to-face environment as in a face-to-face environment. To provide such an environment, services such as online video conferencing have emerged, and these services have provided an environment in which participants can interact with each other and share various information. The current non-face-to-face environment is being performed based on such a video conference service. Recently, however, cases in which participants feel a sense of distance while using a video conference service are increasing, which is caused by not being in the same space. This sense of distance causes the feeling that smooth communication is not progressing with each other, which causes a problem that does not provide sufficient effects as face-to-face activities. In order to solve the above problems, metaverse-based non-face-to-face services are attracting attention. Metaverse-based non-face-to-face services can interact in the virtual world and continue the same level of activity as the real world regardless of the location in the real world. Therefore, it is attracting attention as an alternative space that can overcome physical and environmental problems that cannot be performed in the real world and carry out activities in the real world. However, since the current metaverse technology is not even clearly defined, continuous research is needed to use the metaverse as an alternative to the real world in the future.

On the other hand, the matters described as the background art above are only for improving understanding of the background of the present invention, and should not be taken as an admission that they correspond to prior art already known to those skilled in the art. will be.

3 is a basic flow chart for art transaction according to an embodiment of the present invention.

As shown, in the control method of the server 100 for providing a metaverse-based art trading service according to an aspect of the present invention, the server 100 receives art data from the first terminal 200 (S310). ), the received artwork data is stored (S320), and the artwork image for the stored artwork data is output on the metaverse space (S330).

The metaverse space is an image in which an indoor space modeled after an exhibition is embodied, and an art work image is an image displayed in a shape displayed on any one of the wall surface, floor surface, ceiling surface, and empty space forming the indoor space.

Users of terminals connected to the metaverse space can enjoy the artwork images displayed in the metaverse space through their characters.

Specifically, an artist who is a user of the first terminal 200 may display his or her artwork on the metaverse space through the server 100 or trade the displayed artwork.

In addition, the first terminal 200 may store artwork data in the form of an NFT in a blockchain through the server 100 .

The art object data includes metadata, and the art object image is an image of at least one of a flat work (a drawing accommodated in a frame, etc.) and a three-dimensional work (a sculpture, miscellaneous goods, clothing, etc.).

At this time, when a transaction request is obtained from the second terminal 300, the server 100 matches the transaction information of the transaction request to the artwork data and stores it in the block chain (S340).

The transaction information is data including personal information (contact information, place of residence, identification card image, etc.) of the art buyer, who is the user of the second terminal 300, transaction amount, transaction date, and art product delivery schedule.

To this end, in performing step S320 by the server 100, the server 100 may identify metadata including at least one of an identifier (artwork producer), an owner, a name, license information, and a transaction price from the art object data. there is.

On the other hand, in the server 100 performing step S340, the server 100 tracks the location of the original article and the location of the second terminal 300 for the corresponding artwork data, and the location information of the second terminal 300. When the positional information of the genuine article coincides with the second terminal 300, a user interface (UI) for acquiring the art is provided.

In this case, when the server 100 receives a user command for the UI for acquiring the artwork from the second terminal 300, transaction information on the artwork data may be matched with the artwork data and stored in the blockchain.

On the other hand, the transaction request may be any one of a transaction request through inquiry and selection of some artworks for a desired condition (metadata) among all artworks registered in the server 100 and a transaction request for a specific artwork image.

Specifically, if the transaction request is for inquiry and selection of artworks, the server 100 sends a plurality of data (server 100) including artwork data registered by the first terminal 200 to the second terminal 300. While transmitting metadata for each art work data that is registered and tradable), receiving selected information among metadata for each of a plurality of data from the second terminal 300, and requesting a transaction based on the received information. can approve

For example, when the server 100 receives a request for searching for an artwork from the second terminal 300, the server 100 identifies a plurality of pieces of art data that can be traded, and transmits metadata for each of the identified pieces of art data to a plurality of pieces. It may be provided to the second terminal 300 together with the artwork image for each artwork data.

The art buyer may select at least one piece of information to be purchased from among the provided data and input the second terminal 300 through the UI provided by the server 100. In order to retrieve data, the second terminal 300 may perform a search through a UI provided by the server 100 .

When obtaining a transaction request for the selected information, the server 100 performs step S340 to complete the transaction for the selected information (the server 100 obtains payment details through the second terminal 300) there is.

On the other hand, if the transaction request is for an artwork image, the server 100 identifies the offer price included in the transaction request, and if the transaction price in the metadata for the artwork data and the identified offer price match, approves the transaction request; When an approval event of the transaction request occurs, in performing step S340, the owner of the metadata of the artwork data that is the target of the transaction request may be updated.

As an embodiment, in the control method of the server 100 according to the present invention, the server 100 exhibits, from the second terminal 300, artwork data registered as an owner by the user of the second terminal 300. request can be received.

As another embodiment, when the server 100 receives an exhibition request from the first terminal 200, which is the terminal of the identifier of the art object data that has been transacted, the server 100 sends the second terminal 300, which is the terminal of the owner of the art object data that has been transacted, free of charge. A UI for selecting one of exhibitions, paid exhibitions, and non-compliance with exhibitions may be provided.

At this time, the second terminal 300 obtains a user command for selecting one of free exhibition, paid exhibition, and non-compliance with the exhibition through the UI and transmits the command to the server 100, and the server 100 selects the paid exhibition. Upon receiving, the server 100 transmits a fee payment request to the first terminal 200 at a certain rate based on the transaction price of the corresponding artwork data recorded on the block chain, and registers the previously registered amount of the fee payment request. An amount excluding the exhibition cost may be provided as points for the second terminal 300 .

At this time, the points are used as tokens to pay for the use of the art trading service and the use of the art education service.

As another embodiment, when the server 100 receives a sale request for artwork data in which the user of the second terminal 300 is registered as an owner, from the second terminal 300, the server 100 responds to the sale request. By implementing and displaying the artwork data according to the image in the metaverse space, users of other terminals can view the corresponding artwork image through the metaverse space. In addition, when a request for inquiry and selection of an art object is received from another terminal, metadata for the corresponding art object data may be provided to suggest that it is in a state of being available for sale.

When the server 100 performs step S320, the server 100 may analyze the artwork image to determine the category of the artwork image, and search the transaction history of the identifier for the determined category.

At this time, the server 100 identifies the number of transaction requests received for each image and the transaction price per image according to the searched transaction history, and based on the identified number of transaction requests and the identified sales price, the artwork image Calculate the expected transaction price for

When the difference between the transaction price included in the metadata of the artwork data and the calculated expected transaction price exceeds a threshold value, the server 100 may transmit a transaction price adjustment request to the first terminal 200 when the transaction price is less than the expected transaction price.

At this time, when the server 100 determines the category of the artwork image, the server 100 may identify production information by performing image analysis on the artwork image.

The production information is data on line thickness, color, object, composition, contrast, three-dimensionality, coloring material, and coloring tool.

The server 100 determines the style of the work and the theme of the work based on the identified production information, and searches for data of a plurality of works sharing the same style and theme as the determined style and subject of the work.

The server 100 may determine a category having a ratio equal to or higher than a threshold among categories for each of a plurality of pieces of searched work data as a category of an artwork image.

For example, the server 100 searches for a plurality of work data in which the first painting style of the first artwork image and the same work style and work theme as the first subject are matched, and identifies a category for each of the plurality of work data. As a result, Among the plurality of pieces of data identified by the server 100, the first category is 30%, the second category is 50%, the third category is 13%, and other (category unclassified) can be analyzed as taking up the remaining ratio. there is.

At this time, when the threshold is 17%, the server 100 determines that the first category and the second category are categories for the first work image, and for the first work data of the first work image, the first category and the second category The second category may be stored as metadata.

Accordingly, when the second terminal 300 transmits a category search request for at least one of the first category and the second category to the server 100, the server 100 sends the first art work in response to the search request. Images may be provided to the second terminal 300 .

4 is a basic flowchart for art education according to an embodiment of the present invention.

As shown, in the control method of the server 100 for providing a metaverse-based art education service according to an aspect of the present invention, the server 100 sends the first terminal 200 from the first terminal 200. When expert information on the expert of is acquired (S410), the expert information is stored (S420).

The expert information is data on the artist's career (degree, awards, submitted works, etc.), tuition fee, available class hours, available class categories (painting style, subject), and art works on sale, who are users of the first terminal 200.

When the server 100 obtains a training request for expert information from the third terminal 400 (S430), the server 100 collects art activity information through the third terminal 400 and transfers the collected art activity information to the metaverse space. It can be shared with the first terminal 200 in real time through (S440). For example, the server 100 may collect art action information by providing a UI including a tool (painting module) for drawing to the third terminal 400 and acquiring a user command for the tool through the UI. there is.

The training request includes data on at least one of a training time, the number of works to be made, a category for which training is desired, a payable tuition fee, an artist to be instructed in education, and an artwork image to be made.

Specifically, when the server 100 performs step S440, the server 100 provides a UI for collecting a user input for an art activity to the third terminal 400, and provides a UI according to the art activity on the metaverse space. While outputting the first image (an artwork image created by the user of the third terminal 400), the first image is updated in real time by continuously reflecting user input through the UI, and corrections and deletions are performed from the third terminal 400. Upon obtaining the request, updating of the first image may be terminated.

Thereafter, the server 100 acquires the correction information generated for the art action information from the first terminal 200 in real time (S450), and collaborates on the metaverse space based on the obtained correction information and art action information. The simulation may be output (S460). For example, the server 100 may collect correction information by providing a UI including a drawing tool to the first terminal 200 and obtaining a user command for the tool through the UI.

Accordingly, the server 100 stores the image change image according to the art action information and the image change image according to the correction information as a collaborative work simulation, outputs the stored collaborative work simulation on the metaverse space, and the third terminal 400 ) can provide a service so that the user can receive education on images according to art activity information.

On the other hand, in the server 100 performing step S460, the server 100 stores the collaborative work simulation in the form of NFT in the blockchain and shares it with a plurality of electronic devices constituting the blockchain network, thereby NFT for the collaborative work simulation. transaction can be supported.

If obtained, step S440 may be performed.

That is, a student receiving art education, a user of the third terminal 400, may agree or reject a profit ratio suggested by a user of the first terminal 200, an artist selected by the student.

Meanwhile, when the server 100 transmits a consent request to the third terminal 400, the server 100 redistributes the profit ratio from the third terminal 400 when the server 100 obtains a rejection from the third terminal 400. You may receive a request for either a suggestion for and a selection of other artists.

At this time, when the server 100 receives the proposal for redistribution of the revenue ratio, the server 100 transmits the proposal for the redistribution of the revenue ratio to the first terminal 200, and the first terminal 200 accepts the proposal. is received, step S440 is performed, but if a rejection is received from the first terminal 200, a request for selecting another artist may be transmitted to the third terminal 400.

In one embodiment, when a non-public time range is identified from the sales request in the playback time range of the collaborative simulation, the server 100 stores correction information for the non-public time range in off-chain, and correction and correction information for the public time range You can only sell collaborative simulations that contain information only.

At this time, if the sale of the collaborative work simulation containing only the correction information for the published time range is successful, the server 100 allocates a first value obtained by adding a predetermined penalty to the first ratio of the selling price to the first terminal 200 , the remaining amount may be allocated to the third terminal 400, and the artist may be held responsible for a decrease in sales due to hiding some editing techniques.

As an embodiment, the server 100 obtains educational information, which is a work method for art data registered for the user of the first terminal 200, and registers the user of the first terminal 200 as a class available time. Art education for the user of the third terminal 400 may be executed even at other times.

For example, when the server 100 performs step S430, if the education request is for any one artwork image registered for the user of the first terminal 200, the server 100 sends the first terminal 200 When educational information including sketch information, color combination information, and step-by-step work information is obtained based on at least one artwork data pre-registered by, and the server 100 performs step S440, the server 100 On the metaverse space, based on the acquired educational information, a work simulation of an art object image for art object data may be generated and provided to the third terminal 400 .

The work simulation is an image of a process of creating an image of an art work, in which work steps are divided in order by educational information.

Thereafter, the server 100 transmits a second image for job simulation from the third terminal 400 (an image drawn by the user of the third terminal 400 imitating an artwork registered for the user of the first terminal 200) is obtained, and in performing step S450 by the server 100, the server 100 analyzes the art activity information for the second image based on the education information, and selects a step requiring correction among the work steps of the art activity information. It is possible to identify and provide the identified time range to the first terminal 200 .

For example, the server 100 compares the second image with a job simulation for each job step, determines whether a pixel difference exceeds a threshold value, and determines whether a pixel difference exceeding a threshold value occurs is a step requiring correction. can be identified by

According to another example, the server 100 obtains a first tool usage order according to the education information from the first terminal 200 . The task in which the difference occurs by identifying the order of using the second tool for the second image of the third terminal 400 based on the art action information on the second image and comparing the order of using the first tool and the order of using the second tool. Steps can be identified as those requiring correction.

Accordingly, the server 100 may provide a step requiring correction identified to the first terminal 200 and obtain correction information only for this.

As an embodiment, as shown in FIG. 8 , when the server 100 includes a memory 110 and a communication unit 120 and the server 100 obtains additional correction information from the first terminal 200 Through the processor 130, the work step in which the additional correction information is generated and the additional correction information are obtained as training data, and the learned model is re-learned to identify the step requiring correction.
