Description

Technical Field

[0001] The present invention relates to a technology for handling digital art, and particularly to a technology effective for application to a digital art exhibition system that exhibits digital art borrowed from an owner.

Background Art

[0002] The use of NFT (Non-Fungible Token), a technology for realizing unique and irreplaceable data units on a blockchain, has been rapidly expanding. By associating (NFTizing) digital data that can be easily replicated with NFT, the digital data can be made unique and assetized, and can be made the subject of transactions. As digital data that is the subject of transactions, for example, in addition to being used for various contents such as trading cards, in-game characters, and items, it is also widely used for digital art (art works) produced by artists.

[0003] As a technology for applying NFT to digital art, for example, in International Publication No. 2020 / 080537 (Patent Document 1), accurate information regarding the origin and history of art and the like in circulation can be recorded and managed on a blockchain, and in addition to copyright income and ownership sales income related to the art and the like, it is possible to receive a reduction income at the time of secondary sales and a distribution payment when secondary creations are sold. A mechanism is described.

[0004] Further, in Japanese Patent Application Laid-Open No. 2021-189475 (Patent Document 2), objects such as in-content currency obtained by a user using contents such as a game can be converted into cryptocurrency, and the cryptocurrency can be used to trade the usage rights of digital works such as in-game characters and items. By enabling this, it becomes possible to own and monopolize these digital works, and a mechanism is described that enables general users who are not familiar with cryptocurrency and the like to trade the usage rights of digital works as long as they play the contents. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] International Publication No. 2020 / 080537 [Patent Document 2] Japanese Patent Publication No. 2021-189475 [Overview of the project] [Problems that the invention aims to solve]

[0006] For example, according to the technology described in Patent Document 1 above, the owner of digital art can convert it into an NFT and generate revenue by trading it on a marketplace. However, the revenue is from buying and selling, and it is strongly implied that NFT art is treated as an investment target that focuses on its asset value. In order to effectively utilize the value of NFT art as a work of art, it is important to actually exhibit and allow people to see and experience it. On the other hand, managers and organizers of facilities and events where people gather do not necessarily want to own the NFT art themselves, but they have a need to display NFT art that harmonizes with the space they manage in order to increase user satisfaction.

[0007] Furthermore, while the technology described in Patent Document 2 above makes it possible to trade the right to use (ownership) digital copyrighted works, it is intended for users to acquire the right to use (ownership) themselves, and it assumes that users can use the content (for example, by playing a game) in order to obtain the cryptocurrency that serves as consideration for acquiring the right. Therefore, it does not satisfy the need to realize a mechanism for exhibiting NFT art that the user does not own, as described above.

[0008] Therefore, the objective of the present invention is to provide a digital art exhibition system that enables NFT art to be used not only as an investment target through trading on a marketplace, but also as an effective art form to be exhibited and utilized, while also allowing the owner to generate revenue.

[0009] The aforementioned and other objectives and novel features of the present invention will become apparent from the description herein and the accompanying drawings. [Means for solving the problem]

[0010] A brief overview of some of the representative inventions disclosed in this application is as follows:

[0011] A representative embodiment of the present invention is a digital art exhibition system for exhibiting digital art borrowed by an exhibitor from an owner, comprising: a marketplace processing unit that issues an NFT certificate relating to the digital art put up for sale by the owner and processes transactions relating to the digital art; a borrowing processing unit that registers the lending conditions relating to the digital art set by the owner in the NFT certificate, registers the borrowing conditions in the NFT certificate upon receiving a request from the exhibitor to borrow the digital art, and records the exhibition conditions relating to the digital art set by the exhibitor; and an exhibition processing unit that, when it is determined that the user is located in a predetermined exhibition area based on the user's location information, extracts digital art that can be exhibited in the exhibition area from among the digital art borrowed by the borrowing processing unit, and displays the extracted digital art in various ways according to the exhibition conditions relating to the digital art on an image of the exhibition area taken by the user's terminal. [Effects of the Invention]

[0012] The effects obtained by some of the representative inventions disclosed in this application can be briefly explained as follows:

[0013] In other words, according to a typical embodiment of the present invention, NFT art can be used not only as an investment target through trading on a marketplace, but also by being exhibited and utilized in an effective form as an actual work of art, while the owner can also generate revenue. [Brief explanation of the drawing]

[0014] [Figure 1] This figure shows an overview of an example configuration of a digital art exhibition system, which is one embodiment of the present invention. [Figure 2] This figure outlines an example of the processing flow related to a marketplace in one embodiment of the present invention. [Figure 3] This figure outlines an example of another processing flow related to a marketplace in one embodiment of the present invention. [Figure 4] This figure outlines an example of the workflow for borrowing digital art in one embodiment of the present invention. [Figure 5] This figure outlines an example of the display process of digital art using AR display in one embodiment of the present invention. [Modes for carrying out the invention]

[0015] Embodiments of the present invention will be described in detail below with reference to the drawings. In principle, the same parts will be denoted by the same reference numerals in all the drawings used to describe the embodiments, and repeated descriptions will be omitted. On the other hand, a part that is denoted by a reference numeral and described in one drawing may be referred to again in the description of another drawing, although it will not be shown again.

[0016] <Overview> One embodiment of the present invention is a digital art exhibition system that displays NFT art using AR (Augmented Reality) in places that are compatible with art exhibitions and where users may view the exhibited art, such as airport lounges, hotel lobbies, and restaurants, which are only accessible to users who meet certain conditions. The exhibition location is not particularly limited as long as it is a place where art can be exhibited, and may include museums where the exhibition and viewing of art itself is the purpose, as well as restaurants, retail stores, indoor and outdoor event venues, etc. It may be a place that is only accessible to users who meet certain conditions, or it may be a place that anyone can freely enter. In this embodiment described below, an airport lounge will be used as the exhibition location.

[0017] Furthermore, while this embodiment displays NFT art using AR, it is not limited to AR as long as it is a method that can display digital art. For example, it may also be displayed using VR (Virtual Reality), MR (Mixed Reality), SR (Substitutional Reality), XR (Cross Reality / Extended Reality), etc., that is, a display using technology that merges the real world and the virtual world to make people perceive things that do not exist in reality (hereinafter sometimes referred to as "various reality displays").

[0018] In this embodiment, NFT art that matches the atmosphere of the exhibition space, such as an airport lounge, is displayed using AR to merge the physical and virtual spaces. However, these NFT art pieces are assumed to have been borrowed (rented) by the exhibitor, such as the airport lounge, from their respective owners. In other words, the exhibitor, such as the airport lounge, does not display NFT art that they own (this does not exclude the display of NFT art that they own), but rather, on behalf of the NFT art's owner, they borrow it from the owner (obtain permission to use it for display) and then display it.

[0019] And airport lounge users can view the NFT art displayed through AR display and can also purchase the works they like. As a result, the owner of the NFT art can increase income by lending the NFT art and can also obtain income from selling it when it is purchased.

[0020] <System Configuration> FIG. 1 is a diagram schematically showing a configuration example of a digital art display system according to an embodiment of the present invention. The digital art display system 1 includes, for example, a digital art display server 10, a blockchain 5 configured on the Internet via a blockchain service not shown, and a user terminal 41 such as a smartphone held by a user 4 such as an airport lounge.

[0021] The digital art display server 10 is constituted by, for example, a server device, a virtual server constructed on a cloud computing service, a PC, etc., and by a CPU (Central Processing Unit) not shown, an OS (Operating System) and a DBMS (DataBase Management System) deployed from a recording device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) onto a memory, middleware such as a Web server program, and software operating thereon, various functions related to borrowing and displaying NFT art are realized.

[0022] This digital art exhibition server 10 includes various components, such as a marketplace processing unit 11, a borrowing processing unit 12, and an exhibition processing unit 13, which are implemented as software. It also includes data stores, such as a digital art database (DB) 14 and an exhibition conditions DB 15, which are implemented as databases or files. In the example in Figure 1, these components are shown as if they were implemented on a single server system, but this is a logical representation. In reality, some or all of these components may be implemented as separate servers, systems, services, etc., and may be configured to cooperate via a network not shown.

[0023] The marketplace processing unit 11 has marketplace functionality for processing transactions related to NFTs, such as buying and selling NFT art. It may use OpenSea (registered trademark, https: / / opensea.ip / ) or other existing NFT marketplace platforms, or it may implement its own NFT marketplace platform. Digital art owners 2 can list and trade their digital art 21 on the marketplace via the marketplace processing unit 11.

[0024] When Digital Art 21 is listed on the marketplace, the marketplace processing unit 11 issues an NFT certificate on Blockchain 5 to prove its authenticity. This can be done, for example, by registering predetermined artwork information related to Digital Art 21 using the smart contract function of Blockchain 5. Alternatively, the data and artwork information of the listed Digital Art 21 may be registered in Digital Art DB 14. For settlement related to the transaction, for example, cryptocurrency (crypto assets) may be used on Blockchain 5, or other payment methods such as credit cards, miles, or points may be used.

[0025] The borrowing processing unit 12 has the function of borrowing (obtaining permission for exhibition) digital art 21 that is listed on the marketplace and registered in the digital art DB 14, and for which the digital art owner 2 has registered in an NFT certificate or similar document that it is available for loan, and which is a candidate for exhibition in an exhibition area 31 such as an airport lounge. The borrowed digital art 21 is registered in the exhibition conditions DB 15 along with information such as the borrowing period and the exhibition area 31 to which it will be exhibited, and is also registered in the NFT certificate. If a rental fee is incurred when borrowing, payment may be made in the same way as settlement of transactions on the marketplace, for example, by sending cryptocurrency (crypto asset) to the digital art owner 2 on the blockchain 5, or by using other payment methods such as a credit card.

[0026] Exhibitor 3 will select and borrow digital art 21 that matches the atmosphere of the exhibition area 31, such as an airport lounge. This can be done manually, or the borrowing processing unit 12 can automatically select digital art 21 that meets the specified conditions after the desired conditions have been specified. For example, AI could be used to extract suitable digital art 21 based on image data of the exhibition area 31. Furthermore, the lending conditions (period, rent, etc.) that the digital art owner 2 has set in advance and registered in the exhibition conditions DB 15 or the NFT certificate of blockchain 5 could be matched with the borrowing conditions (period, rent, etc.) desired by Exhibitor 3.

[0027] Regarding the lending and borrowing of digital art 21, for example, the borrower, exhibitor 3, will receive permission from the lender, the digital art owner 2, to use the digital art 21 for exhibition based on its copyright. However, similar to the lending and borrowing of physical artworks, only one exhibitor 3 may borrow any digital art 21 at any given time, and only that exhibitor 3 may have exclusive use for exhibition, or multiple exhibitors 3 or third parties may borrow it simultaneously. Furthermore, even if only exhibitor 3 has exclusive use of the digital art 21, it may be possible to exhibit it simultaneously in multiple exhibition areas 31 managed by exhibitor 3.

[0028] The exhibition processing unit 13 extracts digital art 21 from the borrowing processing unit 12 that matches the location, exhibition period, and other exhibition conditions of the exhibition area 31, and has the function of displaying the digital art 21 in an appropriate location according to the exhibition conditions using AR display when a user 4 using the exhibition area 31, such as an airport lounge, takes a photograph of the exhibition area 31 using the camera function via an application (not shown) installed on the user terminal 41.

[0029] For example, the AR display on the user terminal 41 can be configured such that the display processing unit 13 sends the data necessary for AR display to the user terminal 41, and the user terminal 41 receives the data, processes it for AR, and displays it. Alternatively, the display processing unit 13 can perform the necessary processing for AR display, and the user terminal 41 can simply display the content sent from the display processing unit 13 as is, or a combination of these configurations may be used.

[0030] The exhibition area 31 where the digital art 21 is displayed is not fixed to a specific location. For example, in the case of an airport lounge, it may be exhibited in multiple airport lounges nationwide at regular intervals, or, if possible depending on the loan / borrowing conditions of the digital art 21, it may be exhibited simultaneously in multiple airport lounges. Furthermore, even in the same airport lounge, different digital art 21 may be exhibited depending on the attributes of each user 4, and for the same user 4 who visits multiple times, different digital art 21 may be exhibited each time.

[0031] Furthermore, as a method for obtaining attribute information for each user 4, for example, each user 4 can inquire about attribute information by installing and using a member application (including an application used exclusively for facilities such as airport lounges) provided by or available at the facilities and equipment of transportation companies such as airlines, railway companies, bus companies, and taxi companies (for example, facilities and equipment with fixed geographical locations such as airport lounges, railway lounges, bus stops, and taxi waiting areas as described in this embodiment). The application may also be configured to include and provide various functions of the user terminal 41 as described in this embodiment. Moreover, if user 4 has obtained a marketplace account, as described later, through linked authentication with the above member information, it is also possible to configure the system so that users can log in to the application and the marketplace simultaneously by launching the application and logging in.

[0032] Whether or not the target user 4 is located within an exhibition area 31 such as an airport lounge can be determined, for example, by checking whether the latitude and longitude information acquired by the GPS (Global Positioning System) function of the user terminal 41 is within a predetermined latitude and longitude range. Not limited to GPS, other known and conventional technologies can be used as appropriate, such as the user terminal 41 detecting predetermined beacon signals or WiFi signals transmitted within the exhibition area 31 and determining which exhibition area 31 the user is located within based on the identification information of these signals. Through these methods, location-based AR that displays digital art 21 according to the location of user 4 can be realized.

[0033] Furthermore, the exhibition area 31 where the digital art 21 is displayed is not limited to facilities with a fixed geographical location, such as airport lounges, railway lounges, bus stops, and taxi waiting areas, as described in this embodiment. For example, it may be possible to determine whether a user is using (riding on) non-fixed equipment such as an airplane or vehicle using beacon signals or Wi-Fi, and to display the digital art 21 in AR only when such equipment is in use.

[0034] When displaying digital art 21 in an exhibition area 31 such as an airport lounge using AR, for example, a commonly used marker-type AR display is used to display the art according to markers pre-set in the exhibition conditions DB 15, in accordance with the interior design, furniture, fixtures, etc., of the exhibition area 31. In the example shown in Figure 1, the digital art 21 is displayed in AR on the screen of the user terminal 41, on top of a table installed in the exhibition area 31.

[0035] User 4 can also purchase the digital art 21 displayed in AR on the user terminal 41 if they wish. For example, by pressing the "Purchase" button (not shown) displayed on the screen along with the AR-displayed digital art 21, User 4 executes the purchase process (buy and sell transaction with the digital art owner 2) in the marketplace processing unit 11. This allows User 4 to purchase the digital art 21 and become its new owner. If User 4 does not have an account in the marketplace at this time, they will register for a new account before making the purchase.

[0036] If user 4 purchases digital art 21, user 4 will become the new owner 2 of the digital art 21, and the loan / borrowing agreement between the original digital art owner 2 and exhibitor 3 may be considered terminated. In this case, unless the new digital art owner 2 relists the digital art on the marketplace and exhibitor 3 takes over the loan process, the digital art will not be viewable by third parties on the marketplace, and AR display will not be performed in the exhibition area 31.

[0037] Alternatively, in order to ensure that the digital art 21 is exhibited in the exhibition area 31 for a predetermined period, the purchase process by the user 4 may be treated as a purchase reservation, and transaction processing such as settlement and transfer of ownership may be carried out in the marketplace processing unit 11 after the predetermined exhibition period has ended. Or, after the transaction processing has been carried out, AR display in the exhibition area 31 may be continuously made possible during the exhibition period (the status of the lessor is transferred to the new digital art owner 2, and the state in which the exhibitor 3 is renting it is maintained).

[0038] Furthermore, if user 4 likes the digital art 21 displayed in AR on user terminal 41, they may, for example, give a "tip" or press a "like" button to rate and vote. Miles or points may be used for "tipping". Also, for example, user 4 may enter comments on the AR-displayed digital art 21 from a specific viewpoint, and may also be able to view comments, including those from other users 4.

[0039] Digital art pieces 21 that are judged to have a certain level of evaluation or popularity based on the number of "tips" and "likes," the content of comments, etc., may be given priority for exhibition in exhibition area 31. Conversely, works that have lost popularity or are old may be removed from exhibition. When determining popularity, in addition to indicators such as the number of "likes," for example, the length of time the AR display is taken from log information may be used, and works with longer AR display times may be treated as having a higher evaluation and popularity.

[0040] <Processing flow> Figure 2 is a diagram illustrating an example of the processing flow related to a marketplace in one embodiment of the present invention. Here, an example of the processing flow is shown when a digital art owner 2 newly lists their own digital art 21 on the marketplace.

[0041] Digital art owner 2 first accesses the digital art exhibition server 10 using a web browser or marketplace application installed on a terminal such as a smartphone or PC (not shown) and logs in to the marketplace (S01). The marketplace processing unit 11 performs the login process (S02). If digital art owner 2 does not have a marketplace account, a new account is created and then they log in.

[0042] Subsequently, the digital art owner 2 enters information relating to the digital art 21 to be exhibited (S03), and then uploads the data of the digital art 21 to the marketplace (or digital art exhibition server 10) via the marketplace processing unit 11 (S04). The information relating to the digital art 21 to be exhibited includes, for example, the title of the work, the creator, the date of creation, and the selling price.

[0043] In the Marketplace Processing Unit 11, the uploaded digital art 21 data is registered in the Digital Art DB 14 (or Blockchain 5) (S05), an NFT certificate for the digital art 21 is issued (minted) on Blockchain 5 (S06), and listing processing is performed such as making the digital art 21 publicly available for trading on the Marketplace (S07). The NFT certificate, using the smart contract function of Blockchain 5, records information such as the artwork information of the digital art 21, as well as the owner's history (owner, date of ownership transfer, etc.) and the loan history (borrower, loan period, etc.). The addresses (wallets) of the creator, owner, and borrower on Blockchain 5 are also associated with the certificate.

[0044] Meanwhile, the digital art owner 2 inputs information regarding whether or not to allow the lending of the submitted digital art 21 for exhibition, and if so, the lending conditions (period, rent, exhibition method, etc.) (S08). The borrowing processing unit 12 registers this information in the exhibition conditions DB 15 and also registers it in the NFT certificate using the smart contract function of blockchain 5 (S09). This allows the digital art owner 2 to list the digital art 21 on the marketplace and lend it to the exhibitor 3 for display in the exhibition area 31.

[0045] Figure 3 is a diagram illustrating an example of another processing flow related to a marketplace in one embodiment of the present invention. Here, an example of the processing flow when a user purchases a new digital art 21 on the marketplace and becomes the digital art owner 2 is shown. In addition to the case where a general user purchases a new digital art 21 on the marketplace, it also includes the case where a user 4 in the exhibition area 31 purchases a digital art 21 that is being displayed in AR, as will be described later.

[0046] Similar to the example in Figure 2 above, first, the user (later the new digital art owner 2) accesses the digital art exhibition server 10 using a device such as a smartphone and logs into the marketplace (S11), and the marketplace processing unit 11 performs the login process (S12).

[0047] Subsequently, the user uses an application for the marketplace to view the digital art listed on the marketplace (S13) and makes a purchase request for the desired item (S14). The marketplace processing unit 11 processes the payment for the purchase using cryptocurrency, credit card, miles, points, etc. (S15). Once payment is made, the smart contract function of blockchain 5 registers and updates the NFT certificate for the target digital art 21, designating the purchasing user as the new owner (new digital art owner 2) (S16).

[0048] On the other hand, similar to the example in Figure 2 above, the new digital art owner 2 inputs information regarding whether or not to permit lending out the purchased digital art 21 for exhibition, and if so, the lending conditions (period, rent, exhibition method, etc.) (S17). The borrowing processing unit 12 registers (or updates) this information in the exhibition conditions DB 15 and also registers (or updates) it in the NFT certificate related to the digital art 21 using the smart contract function of the blockchain 5 (S18). This makes it possible for the new digital art owner 2 to lend out the digital art 21 to the exhibitor 3 and have it exhibited in the exhibition area 31.

[0049] As mentioned above, if the digital art 21 to be purchased is currently on display (on loan) in the exhibition area 31, it may be treated as a purchase reservation with the sale suspended until the end of the exhibition period, or the status of the previous digital art owner 2 as lender may be transferred to the new digital art owner 2, and the exhibition may continue.

[0050] Figure 4 is a diagram illustrating an example of the process for borrowing digital art 21 in one embodiment of the present invention. Here, an example of the process for exhibitor 3 to borrow digital art 21 that is listed on the marketplace as a candidate for exhibition is shown.

[0051] An exhibitor 3 who wishes to exhibit digital art 21 in an exhibition area 31 such as an airport lounge accesses the digital art exhibition server 10 using a web browser or exhibition application installed on a terminal such as a smartphone or PC (not shown) to display a list of digital art 21 that can be exhibited (S21). At this time, the borrowing processing unit 12 of the digital art exhibition server 10 extracts and obtains a list of digital art 21 that are registered in the digital art DB 14 (or located on the blockchain 5) and whose lending conditions and exhibition conditions set by the digital art owner 2 (for example, lending period, rent, lending area or location, restrictions on the method of exhibition, etc., including the fact that it has not been lent to anyone else in the case of an exclusive lending) match the desired conditions specified by the exhibitor 3 (S22).

[0052] Subsequently, exhibitor 3 selects from the list of available digital art pieces 21 to actually borrow and exhibit (S23), enters the borrowing conditions (for example, the borrowing period and information about the exhibition area 31 to be exhibited) (S24), and submits an application for borrowing (S25). As mentioned above, when selecting the digital art piece 21, exhibitor 3 may manually select one that matches the atmosphere of the exhibition area 31, such as an airport lounge, or they may specify their desired conditions in advance, and the borrowing processing unit 12 may automatically select one that meets those conditions. Alternatively, AI may be used to select a suitable piece based on image data of the exhibition area 31.

[0053] The borrowing processing unit 12 of the digital art exhibition server 10, upon receiving the borrowing application, updates the NFT certificate by registering the information of the borrower, exhibitor 3, the loan / borrowing period, and other information included in the application information into the NFT certificate using the smart contract function of blockchain 5 (S26). As a result, exhibitor 3 is deemed to have borrowed the digital art 21.

[0054] Exhibitor 3 sets the exhibition conditions for the borrowed digital art 21 so that it is displayed in the appropriate location and in the appropriate form in AR within the exhibition area 31 (S27). The borrowing processing unit 12 (or exhibition processing unit 13) of the digital art exhibition server 10 registers the information of the set exhibition conditions in the exhibition condition DB 15 (S28). The exhibition condition information may include, for example, latitude and longitude range information that identifies the exhibition area 31, beacon signal identification information, marker information that identifies the exhibition location within the exhibition area 31, and information on the size, orientation, and other display settings of the digital art 21 when it is displayed.

[0055] Figure 5 is a diagram illustrating an example of the display process of digital art 21 using AR display in one embodiment of the present invention. Here, an example of the process flow for displaying matching digital art 21 using AR when a user 4 is located within an exhibition area 31 such as an airport lounge is shown.

[0056] The user terminal 41 held by user 4 acquires location information such as latitude and longitude using the GPS function at regular intervals, for example, by using a dedicated application for realizing AR display (for example, an airline application that can be used by airport lounge users) (S31). The user then queries the digital art display server 10 to find out whether or not there is a digital art piece 21 that can be displayed at that location, that is, whether or not user 4 is in any of the exhibition areas 31 and whether or not there is a digital art piece 21 that can be displayed in that exhibition area 31 (S32).

[0057] The exhibition processing unit 13 of the digital art exhibition server 10 refers to the exhibition conditions DB 15 (or blockchain 5) to obtain a list of digital art 21 that exhibitors 3 have currently borrowed and are available (S33). This list may be obtained each time an inquiry is received from the user terminal 41, as shown in Figure 5, or it may be reused from a list that has been obtained separately at a frequency of about once a day.

[0058] Then, the exhibition processing unit 13 determines whether the user 4 is located within any of the exhibition areas 31 based on the location information of each exhibition area 31 registered in the exhibition conditions DB 15 and the location information sent from the user terminal 41. If the user is located within any of the exhibition areas 31, it extracts items from the list of digital art 21 obtained in step S33 that can be exhibited in that exhibition area 31 based on their respective exhibition conditions (S34). All items that match the exhibition conditions, such as exhibition period and exhibition location, may be made available for exhibition, or a predetermined number of popular or new items may be made available for exhibition.

[0059] When determining whether user 4 is located within any of the exhibition areas 31, as described above, for example, latitude and longitude information from GPS may be used, or identification information from a beacon signal received by the user terminal 41 may be used. If user 4 is not located in any of the exhibition areas 31, or if there are no digital art pieces 21 available for display in the exhibition area 31 in which user 4 is located, the process will be terminated.

[0060] In step S34, after obtaining information on the digital art 21 that can be exhibited, the system retrieves the exhibition conditions for each digital art 21 (information on markers that identify the exhibition location, information on the size, orientation, and other display settings when displayed, etc.) from the exhibition conditions DB 15 and responds to the user terminal 41 with this information (S35).

[0061] On the user terminal 41, a dedicated application for AR display is used to display digital art 21 in AR at locations identified by markers specified in the exhibition conditions, based on images of the exhibition area 31 taken by the user terminal 41, according to the display settings specified in the exhibition conditions (S36). This allows the user 4 to view and appreciate the digital art 21 displayed in AR in a way that matches the situation of the exhibition area 31 being photographed by the user terminal 41. If desired, the user can also purchase it from the marketplace. Regarding which digital art 21 to display in AR at locations identified by markers in the exhibition area 31, for example, the exhibitor 3 may pre-set it in the exhibition conditions DB 15, or the exhibition processing unit 13 may dynamically determine it using AI or the like based on the time of day, season, weather, and user 4's attributes, including destination.

[0062] As described above, according to the digital art exhibition system 1, which is one embodiment of the present invention, the owner of the digital art 21 can generate revenue by lending out the digital art 21, and can also make it available for viewing by users 4 through AR display in the exhibition area 31, and can further generate revenue from sales when users 4 purchase it. In other words, the digital art owner 2 can generate revenue by utilizing the digital art 21 they own, not only as an investment target through trading on the marketplace, but also by exhibiting it in an effective form as a work of art.
