Next, an exhibition control method among the information processing methods according to this embodiment will be described with reference to FIG. FIG. 3 is a sequence diagram showing an example of the procedure of the exhibition control method according to the present embodiment.

(Step S101) A user who wishes to exhibit an NFT (NFT holder) uses the user device 2a to display digital content corresponding to the NFT of which he or she is a holder in a virtual reality space. An exhibition request is made to the virtual reality space server 1. The user device 2a transmits exhibition request data to the virtual reality space server 1 in response to an exhibition request operation by a user who desires an exhibition.

The exhibition request data includes the user ID of the user who wishes to exhibit (the user ID who wishes to exhibit), the identifier of the NFT (NFT which corresponds to exhibition request) corresponding to the digital content desired to exhibit (NFT_ID which corresponds to exhibition request), the desired selling price of the NFT which corresponds to exhibition request, etc. This is data that includes. The exhibition request data may further include a desired exhibition position and a desired exhibition size on the virtual reality space.

In the virtual reality space server 1, the reception unit 11 accepts an exhibition request from a user who desires an exhibition by receiving exhibition request data transmitted from the user device 2a. The reception unit 11 causes the storage unit 20 to store the exhibition request data received from the user device 2a.

(Step S102) In the virtual reality space server 1, the exhibition control unit 12 transmits the NFT_ID corresponding to the exhibition request to the NFT management system 4 in response to the exhibition request received by the reception unit 11 from the user who wishes to exhibit. Inquire about desired NFT.

(Step S103) The NFT management system 4 searches the blockchain 5 for the NFT corresponding to the NFT_ID corresponding to the exhibition request in response to the inquiry from the virtual reality space server 1 about the NFT corresponding to the exhibition request. As a result of this search, if an NFT (NFT compatible with exhibition requests) corresponding to the NFT_ID corresponding to exhibition requests is found, the NFT management system 4 acquires NFT data (NFT data compatible with exhibition requests) related to the NFT compatible with exhibition requests. , transmits the NFT data corresponding to the exhibition request to the virtual reality space server 1 as a response to the inquiry of the NFT corresponding to the exhibition request. On the other hand, if the NFT corresponding to the NFT_ID corresponding to the exhibition request (NFT corresponding to the exhibition request) is not found, the NFT management system 4 responds to that effect to the virtual reality space server 1.

When the exhibition control unit 12 in the virtual reality space server 1 receives the NFT data corresponding to the exhibition request from the virtual reality space server 1 as a response to the inquiry about the NFT corresponding to the exhibition request, the exhibition control unit 12 stores the NFT data corresponding to the exhibition request in the storage unit 20. let After this, the process proceeds to the next step S104.

On the other hand, when the exhibition control unit 12 receives a response from the virtual reality space server 1 to the effect that no NFT corresponding to the exhibition request has been found as a response to the inquiry for the NFT corresponding to the exhibition request, the exhibition control unit 12 sends the user device 2a of the user wishing to exhibit the send a notification to that effect. After this, the process in FIG. 3 ends.

(Step S104) In the virtual reality space server 1, the exhibition control unit 12 accesses the object URL included in the metadata included in the NFT data corresponding to the exhibition request, and queries the content database 7 for the digital content desired to exhibit.

(Step S105) In response to the inquiry about the digital content desired to be exhibited from the virtual reality space server 1, the content database 7 transfers data of the digital content desired to be exhibited (digital content data desired to be exhibited) located in the object URL to the virtual reality space server 1. Reply to 1. The digital content data desired to be exhibited is data including main data and metadata of the digital content desired to be exhibited. The metadata of the digital content includes information such as the name of the creator of the digital content, the date and time of creation, and the size of the main data.

In the virtual reality space server 1, the exhibition control unit 12 causes the storage unit 20 to store the desired digital content data to be exhibited, which is obtained from the content database 7.

(Step S106) The exhibition control unit 12 in the virtual reality space server 1 inquires of the user device 2a of the user who wishes to exhibit the desired exhibition position and desired exhibition size of the digital content desired to be exhibited. In inquiring about the desired exhibition position and desired exhibition size of the digital content desired to be exhibited, the exhibition control unit 12 cooperates with the virtual reality space processing unit 10 so that the user who wishes to exhibit the desired exhibition position and desired exhibition size in the virtual reality space. Provides an exhibition position size specification menu for specifying. Thereby, a user who desires an exhibition can specify a desired exhibition position and a desired exhibition size in the virtual reality space using the exhibition position size specification menu.
Note that if the exhibition request data received by the reception unit 11 from the user device 2a of the user who wishes to exhibit includes the desired exhibition position and desired exhibition size in the virtual reality space, the exhibition control unit 12 requests the user device 2a to There is no need to inquire about the desired display position and desired display size of the digital content desired to be displayed.

(Step S107) Using the user device 2a, the user desiring to exhibit specifies the desired exhibit position and desired exhibit size in the virtual reality space using the exhibit position and size designation menu. The user device 2a responds to the virtual reality space server 1 with designation data of the desired exhibition position and desired exhibition size in response to the operation of designating the desired exhibition position and desired exhibition size by the user who desires the exhibition. The designation data of the desired exhibition position and desired exhibition size is the desired exhibition position (desired exhibition position) of the user who wishes to exhibit when exhibiting the desired digital content in the virtual reality space, and the desired exhibition position (desired exhibition position) when exhibiting the desired digital content. This is data indicating the desired exhibition size (desired exhibition size) of the user who wishes to exhibit.

In the virtual reality space server 1, the exhibition control unit 12 receives designation data of the desired exhibition position and desired exhibition size from the user device 2a of the user who wishes to exhibit.

(Step S108) In the virtual reality space server 1, the exhibition control unit 12 determines whether or not a predetermined exhibition enablement condition is satisfied in response to an exhibition request from a user who desires an exhibition. The display possible conditions are shown in the display possible condition information 203.

Here, the display enabling conditions according to the present embodiment will be described with reference to some examples.

[Example 1 of conditions for display]
Example 1 of the display enabling condition is that the user who wishes to display is the holder of an NFT that supports display requests. More specifically, the digital content desired to be exhibited is digital content associated with an NFT recorded on the blockchain 5, and the user who wishes to exhibit is the holder ID corresponding to the NFT associated with the digital content desired to be exhibited. The user must be identified.

The condition that the digital content desired to be exhibited is digital content associated with an NFT recorded on the blockchain 5 is satisfied when the NFT corresponding to the desired exhibition is discovered from the blockchain 5 by the NFT management system 4. On the other hand, if the NFT corresponding to the exhibition request is not found in the blockchain 5, the condition is not satisfied.

The fact that the user who wishes to exhibit is a user identified by the holder ID corresponding to the NFT associated with the digital content that he wishes to exhibit means that the holder ID that is included in the metadata included in the NFT data that corresponds to his desire to exhibit indicates the user who wishes to exhibit. Being an ID is fulfilling. The holder ID (user ID used in the NFT management system 4) of the user who wishes to exhibit is included in the user information 204. Therefore, if the holder ID of the metadata included in the NFT data corresponding to the exhibition request matches the holder ID of the user who wishes to exhibit, which is included in the user information 204, the user who wishes to display the digital content It is satisfied that the user is the user identified by the holder ID corresponding to the associated NFT. On the other hand, if they do not match, the condition is not satisfied.

Example 2 of the exhibition possible condition is that a specific object does not exist at the desired exhibition position in the virtual reality space. If a specific object already exists at the desired display position in the virtual reality space, the desired digital content cannot be displayed at the desired display position. The fact that the specific object does not exist at the desired exhibition position in the virtual reality space is satisfied by the fact that the specific object is not set at the desired exhibition position in the virtual reality space configuration information 201. On the other hand, this condition is not satisfied if a specific object is set at the desired exhibition position in the virtual reality space configuration information 201.
The specific object may be, for example, another exhibit, an advertisement, or a building. On the other hand, the basic composition of the virtual reality space, such as the background, ground, and sky, is excluded from specific objects.

[Example 3 of conditions for display]
Example 3 of display possible conditions is that even if the desired digital content is displayed in the desired display position at the desired display size in the virtual reality space, the digital content desired to be displayed may not be displayed by other objects existing around the desired display position. should not obstruct the user's view of the image. If other objects already exist around the desired display position in the virtual reality space, it is not preferable that the digital content desired to be displayed interferes with the user's visibility of the other objects. Examples of the other objects include guidance display media and advertising media installed in the virtual reality space.

Information about objects that already exist around the desired exhibition position (object shape, position, installation direction, etc.) is shown in the virtual reality space configuration information 201. The digital content you want to exhibit, which is displayed at the desired exhibition size at the desired exhibition position, does not obstruct the user's view of objects that already exist around the desired exhibition position. etc.) based on a predetermined method.

For example, when the user views the object from a predetermined position or direction in the virtual reality space, the object is hidden by the digital content desired to be exhibited (the digital content desired to be exhibited and the object appear to overlap). In this case, it is determined that the digital content that the user wishes to display obstructs the user's visual recognition. On the other hand, if the object is not hidden by the digital content desired to be exhibited (the digital content desired to be exhibited and the object are not visible because they overlap), it is determined that the digital content desired to be exhibited does not obstruct the user's visual recognition.

In addition, in Example 3 of the exhibition possible conditions, other objects that already exist around the desired exhibition position in the virtual reality space may be added to the digital content that is already displayed in the virtual reality space in response to an exhibition request from the user. May be limited.

Example 4 of the exhibition possible condition is that the desired exhibition position of the digital content desired to be exhibited is not included in a predetermined exhibition prohibited area on the virtual reality space. The display prohibited area is indicated in the display possible condition information 203. Therefore, if the desired display position of the digital content desired to be displayed is not included in the display prohibited area indicated by the display possible condition information 203, example 4 of the display possible condition is satisfied. On the other hand, if the desired display position of the digital content desired to be displayed is included in the display prohibited area indicated by the display possible condition information 203, example 4 of the display possible conditions is not satisfied.

[Example 5 of conditions for exhibition]
Example 5 of exhibition possible conditions is when the desired exhibition position of the digital content desired to be exhibited is included in a predetermined exhibition restricted area on the virtual reality space, and the digital content that is already exhibited in the exhibition restricted area (already exhibited content) The number of objects is less than a predetermined upper limit number. The exhibition restriction area and the upper limit number of exhibited contents in the exhibition restriction area (restricted area exhibition upper limit number) are shown in the exhibition possible condition information 203. The already exhibited content that is already exhibited in the exhibition restricted area is the already exhibited content whose exhibition position is included in the exhibition restricted area in the content exhibition information 202. Therefore, in the content exhibition information 202, if the total number of already exhibited contents included in the exhibition restricted area whose exhibition position is shown in the exhibition possible condition information 203 is less than the restricted area exhibition upper limit number shown in the exhibition possible condition information 203, , Example 5 of the display possible condition is satisfied. On the other hand, if the total number of the displayed contents has reached the upper limit for display in the restricted area, example 5 of the display possible condition is not satisfied.

[Example 6 of conditions for display]
Example 6 of the display enablement condition is that the number of digital contents (already exhibited contents) that have already been displayed in the virtual reality space in response to a display request from a user who wishes to exhibit is less than a predetermined upper limit number. The upper limit number of displayed contents for the same user (upper limit number of displayed contents for the same user) is shown in the display possible condition information 203. Existing exhibited content that has already been exhibited in the virtual reality space in response to an exhibition request from a user desiring to exhibit is already exhibited content associated with the ID of the user desiring to exhibit in the content exhibition information 202. Therefore, if the total number of already exhibited contents associated with the exhibition-desiring user ID in the content exhibition information 202 is less than the upper limit number of exhibits for the same user indicated in the exhibition possible condition information 203, example 6 of the exhibition possible condition is satisfied. . On the other hand, if the total number of the displayed content has reached the upper limit number of displayed contents for the same user, example 6 of the display possible condition is not satisfied.

Examples 1 to 6 of the display possible conditions described above may be used alone, or a plurality of them may be used in combination.

When the exhibition control unit 12 determines whether or not a predetermined exhibition possible condition is satisfied in response to an exhibition request from a user who desires an exhibition, the process advances to the next step S109.

The virtual reality space processing unit 10 adds, to the virtual reality space configuration information 201, information regarding the digital content desired to be exhibited, which is displayed at the desired exhibition position and in the desired exhibition size in the virtual reality space. The exhibition control unit 12 sends information regarding the digital content desired to be exhibited displayed at the desired exhibition position in the desired exhibition size in the virtual reality space, the user wishing to exhibit, the NFT data corresponding to the exhibition request, the desired selling price of the NFT corresponding to the exhibition request, etc. It is added to the content exhibition information 202. In the user information 204, the exhibition control unit 12 adds information regarding the digital content desired to be exhibited to the exhibition history of the digital content related to the user desiring to exhibit.

Next, a transaction method among the information processing methods according to this embodiment will be explained with reference to FIG. FIG. 4 is a sequence diagram showing an example of the procedure of the transaction method according to the present embodiment.

(Step S201) A user who wishes to purchase (purchaser) uses the user device 2b to send an NFT purchase request for an NFT (NFT desired to purchase) corresponding to the already exhibited content displayed in the virtual reality space to the virtual reality space. Perform to server 1. The user device 2b transmits NFT purchase request data to the virtual reality space server 1 in response to an NFT purchase request operation by a user who wishes to purchase.

The NFT purchase request data is data including the user ID of the user who wishes to purchase (user ID who wishes to purchase) and the content ID of the exhibited content (existing exhibited content ID) corresponding to the NFT desired to purchase.

In the virtual reality space server 1, the reception unit 11 receives NFT purchase request data from the user device 2b, thereby accepting an NFT purchase request from a user who wishes to purchase.

(Step S202) The transaction processing unit 13 in the virtual reality space server 1 performs purchase price settlement processing with the user device 2b of the user who wishes to purchase. In the purchase price settlement process, the transaction processing unit 13 acquires the desired selling price of the NFT associated with the displayed content ID included in the NFT purchase request data from the content display information 202. The transaction processing unit 13 requests the user device 2b of the user wishing to purchase to pay the purchase price at the desired sale price to a predetermined purchase price payee. As a result, the purchase price at the desired sale price is paid from the user who wishes to purchase the product to the purchase price payee. When the payment of the purchase price is completed, the process advances to the next step S203. On the other hand, if the payment of the purchase price is not completed, the process of FIG. 4 ends.

(Step S203) In the virtual reality space server 1, the transaction processing unit 13 acquires NFT data associated with the exhibited content ID included in the NFT purchase request data from the content exhibition information 202, and metadata included in the acquired NFT data. The ID of the NFT desired to purchase (NFT_ID desired to purchase) is obtained from the data. The transaction processing unit 13 requests the NFT management system 4 to change the holder of the desired NFT (desired purchase NFT_ID) to the desired purchase user (desired purchase user ID) (NFT holder change request). Note that if the user ID of the user who wishes to purchase in the virtual reality space service (user ID who wishes to purchase) is different from the user ID in the NFT management system 4, the transaction processing unit 13 sends the following information to the NFT management system 4. The user ID of the user who wishes to purchase the NFT in the NFT management system 4, which is included in the user information 204, is notified. Here, for convenience of explanation, the following explanation will be given assuming that the user ID of the user who wishes to purchase in the virtual reality space service (user ID who wishes to purchase) and the user ID used in the NFT management system 4 are the same.

(Step S204) In response to the NFT holder change request from the virtual reality space server 1, the NFT management system 4 transfers the holder of the NFT desired to purchase (desired purchase NFT_ID) to the user desired to purchase (desired purchase NFT_ID) to the blockchain 5. (user ID). As a result, the holder of the NFT desired to purchase (NFT_ID desired to purchase) recorded on the blockchain 5 is changed to the user desired to purchase (user ID desired to purchase). After changing the holder, the metadata on the blockchain 5 related to the NFT desired to purchase (NFT desired NFT_ID) records the ID of the user desired to purchase as the holder ID.

(Step S205) The NFT management system 4 sends the virtual reality space server 1 NFT data (purchase holder (changed NFT data) (NFT holder change response). In the virtual reality space server 1 , the transaction processing unit 13 causes the storage unit 20 to store the changed NFT data of the desired purchase holder received from the NFT management system 4 .

(Step S206) In the virtual reality space server 1, the transaction processing unit 13 transmits the changed NFT data to the user device 2b of the user who wishes to purchase, and reports the NFT purchase. Users who wish to purchase can recognize that they are recorded as the holder of the NFT they wish to purchase based on the NFT data in which the holder they wish to purchase has been changed, or access the object URL to purchase the digital content corresponding to the NFT they wish to purchase. You can check it.

(Step S207) In the virtual reality space server 1, the transaction processing unit 13 reports the NFT sale to the user device 2a of the user who requested the display of the already displayed content corresponding to the NFT desired to purchase. This NFT sale report is information indicating that the sale of the NFT corresponding to the exhibited content that was exhibited in the virtual reality space in response to the exhibition request by the exhibition requesting user has been completed. Thereby, the exhibition requesting user can recognize that the sale of the NFT corresponding to the already exhibited content that he/she requested to display has been completed.

(Step S208) In the virtual reality space server 1, the transaction processing unit 13 performs a sale proceeds settlement process with the user device 2a of the user who requested the display of the already exhibited content corresponding to the NFT desired to purchase. In the sale proceeds settlement process, the transaction processing unit 13 acquires the desired sale price of the NFT associated with the displayed content ID of the displayed content corresponding to the NFT desired to be purchased from the content exhibition information 202. The transaction processing unit 13 performs a settlement process to pay the sale proceeds at the desired sale price to a predetermined recipient of the sale proceeds of the exhibition requesting user. As a result, the desired sale price is paid to the predetermined recipient of the sale proceeds of the exhibition requesting user.

(Step S209) The virtual reality space processing unit 10 finishes displaying the exhibited content in the virtual reality space corresponding to the NFT desired to purchase that has been sold through the transaction processing of the transaction processing unit 13.

(Step S210) Various recordings are performed in the virtual reality space server 1. The virtual reality space processing unit 10 deletes information regarding already exhibited content whose exhibition has ended in the virtual reality space from the virtual reality space configuration information 201. The exhibition control unit 12 deletes, from the content exhibition information 202, information regarding already exhibited content whose exhibition has ended in the virtual reality space. In the user information 204, the exhibition control unit 12 adds information regarding the end of exhibition of the already exhibited content to the digital content exhibition history related to the user who requested the display of the already exhibited content whose exhibition has ended in the virtual reality space. The transaction processing unit 13 adds, in the user information 204, the transaction history of buying and selling the NFT desired to purchase for the user desiring to purchase and the user making the display request.
