DETAILED DESCRIPTION OF THE INVENTION

[0011] Embodiment 1 Hereinafter, a first embodiment will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an information processing device 1 according to the present disclosure. The information processing device 1 may be a computer device that operates when a processor executes a program stored in a memory. The information processing device 1 may be, for example, a server device. The information processing device 1 may also be composed of multiple computer devices. In this case, the components or functions that make up the information processing device 1 may be distributed and arranged among the multiple computer devices. The multiple computers may be connected via a network or directly via a cable or the like.

[0012] The information processing device 1 includes an analysis unit 11 and a presentation unit 12. The analysis unit 11 and the presentation unit 12 may be software or modules that are executed by a processor executing a program stored in a memory, or may be hardware such as a circuit or a chip.

[0013] The analysis unit 11 analyzes the credibility of a seller of an item that has been converted into an NFT (Non-Fungible Token) and is being used by a first user in the metaverse space, based on the buying and selling history of the NFT put up for sale by the seller.

[0014] The presenting unit 12 presents the seller's credibility and a link to the seller to the second user.

[0015] 2 is a flowchart showing the flow of the presentation method according to the present disclosure. First, the analysis unit 11 of the information processing device 1 analyzes the credibility of a seller of an NFTized item used by a first user in the metaverse space based on the buying and selling history of the NFTs put up for sale by the seller (step S11). Next, the presentation unit 12 of the information processing device 1 presents the credibility of the seller and a link to the seller to a second user (step S12).

[0016] The information processing device and presentation method according to the first embodiment can encourage users to purchase item data from legitimate sellers in the metaverse.

[0017] Embodiment 2 3 is a block diagram showing an example of the configuration of an information processing device 1000 according to the present disclosure. The information processing device 1000 is a specific example of the above-mentioned information processing device 1. Alternatively, it is also possible to interpret an item sales support server 500, which will be described later, as a specific example of the information processing device 1.

[0018] The information processing device 1000 includes user terminals 100A to 100C, a metaverse operation server 200, an item management server 300, a blockchain network 400, and an item sales support server 500. The user terminals 100A to 100C, the metaverse operation server 200, the item management server 300, the blockchain network 400, and the item sales support server 500 are connected to each other via a network N so that they can communicate with each other. The network N may be, for example, a communication network such as the Internet, an intranet, a mobile phone network, or a LAN (Local Area Network). The network N may be wired or wireless.

[0019] The user terminals 100A to 100C are used by users UA to UC, respectively. When the user terminals 100A to 100C are not distinguished from one another, they may be simply referred to as user terminals 100. When the users UA to UC are not distinguished from one another, they may be simply referred to as user U. The user terminal 100 is, for example, a head mounted display (HMD), a personal computer (PC), a smartphone, a tablet terminal, etc.

[0020] The user terminal 100 includes an interface (referred to as an input interface) through which the user U inputs information. Examples of the input interface include a controller in a head-mounted display, a touch panel in a smartphone, and a keyboard or mouse in a personal computer. The controller may include built-in operation buttons and various sensors that detect the orientation and movement (acceleration, rotation, etc.) of the controller. By inputting information into the user terminal 100 via the input interface, the user U can move an avatar in the metaverse, switch its viewpoint, and make it speak. Furthermore, the user U can select link information displayed in the metaverse or a window by inputting information into the user terminal 100.

[0021] The user terminal 100 has an interface (referred to as a display interface) that displays various information from the user terminal 100 to the user U. The display interface may be configured, for example, as a liquid crystal display. If the user terminal 100 is a head-mounted display, the display interface is worn on the head of the user U and covers the field of view of both of the user's eyes. The user U wearing the head-mounted display can view images displayed on the display interface. The display interface displays various information such as objects in the metaverse and web pages.

[0022] The user terminal 100 may further include a camera that captures the eyes of the user U. The captured image by the camera may be used to analyze the gaze direction of the user U, or analyze pupil information of the user U. For example, it is known that the pupils of the user U dilate when the user U is interested in or concerned with an object.

[0023] The user terminal 100 is a computer device equipped with a processor, memory, etc. The processor in the user terminal 100 executes a predetermined program, causing the user terminal 100 to perform various processes.

[0024] The metaverse operation server 200 is a server that realizes the virtual space of the metaverse. The metaverse operation server 200 may be a server that operates a metaverse game. The metaverse operation server 200 is a computer device equipped with a processor, memory, etc. The processor in the metaverse operation server 200 executes a program, causing the metaverse operation server 200 to perform various processes.

[0025] The metaverse operation server 200 includes a storage unit 210. The storage unit 210 is a storage device accessible by the processor of the metaverse operation server 200. The storage unit 210 includes user information 211 and item information 212. The user information 211 is account information for users UA, UB, and UC who use the virtual space of the metaverse. The user information 211 may further store information on points that each user U can use in the virtual space. The user information 211 may further include information on the location of the user U's avatar, login time, etc.

[0026] The item information 212 is information about items used by each user U. The items may be avatars or items used by avatars (e.g., cars, clothes). The item information 212 includes information about NFTed items. The item information 212 may be information indicating whether or not each user U possesses an item. Alternatively, the item information 212 may include information about a 3D model.

[0027] The metaverse operation server 200 moves the avatar of each user U within the metaverse space in accordance with information input to the user terminal 100. Then, the metaverse operation server 200 or the user terminal 100 generates a screen to be displayed on the user terminal 100 in accordance with the position of the avatar, and displays the generated screen on the display interface of the user terminal 100. The metaverse operation server 200 may transmit information about the position of the avatar or information about the generated screen to the user terminal 100.

[0028] The item management server 300 stores the data of the NFTed item in a specified URL (Uniform Resource Locator). The URL may be included in the NFT as metadata for the item data. The item management server 300 or the user terminal 100 may request the blockchain network 400 to record an agreement to buy or sell the item.

[0029] The blockchain network 400 is composed of multiple nodes and records the buying and selling history of items on a blockchain. Here, a blockchain refers to a combination of multiple blocks representing the buying and selling history of items. The blockchain network 400 may be a public chain or a private chain. In response to a request from the item management server 300 or the user terminal 100, the blockchain network 400 generates a block representing that an item has been transferred to user U, and links the newly generated block to the already generated blockchain. Items may be transferred between users U.

[0030] The item sales support server 500 may be a computer device that operates when a processor executes a program stored in a memory. The item sales support server 500 includes an analysis unit 510, a presentation unit 520, a determination unit 530, and an assignment unit 540. Each of the components that make up the item sales support server 500 may be software or a module that performs processing when a processor executes a program stored in a memory. Alternatively, each of the components that make up the item sales support server 500 may be hardware such as a circuit or a chip.

[0031] The analysis unit 510 is a specific example of the above-mentioned analysis unit 11. The analysis unit 510 analyzes the credibility of the seller of an NFTed item used by a first user (e.g., user UA). The following mainly describes the case of analyzing the credibility of the seller of item IA used by user UA. Note that the analysis unit 510 may analyze the credibility of item IA in advance, or may start analyzing the credibility when user UB or user UC visually recognizes item IA.

[0032] The analysis unit 510 refers to the blockchain maintained by the blockchain network 400 and identifies the seller (e.g., creator) of the NFTized item IA used by the user UA. The analysis unit 510 then extracts from the blockchain the buying and selling history of the NFTs put up for sale by the seller of that NFT, and analyzes the seller's credibility based on the buying and selling history.

[0033] The analysis unit 510 calculates the credibility of a legitimate seller of an NFT so that the credibility is high. The analysis unit 510 may analyze the credibility using AI (Artificial Intelligence) that has learned the trading history of NFTs. The AI ​​may be trained to input data representing the trading history and output the credibility of the seller corresponding to that trading history.

[0034] For example, the analysis unit 510 may calculate a higher credibility for a seller, the more users U who have purchased NFTs from that seller. If many users U have purchased NFTs from a seller, the seller's credibility is considered to be high. Furthermore, the analysis unit 510 may calculate a higher credibility for a seller, the more active the users who have purchased NFTs from that seller are. Activity represents, for example, the number of NFT or FT transactions linked to that user's wallet (address). If a user U who regularly buys and sells NFTs purchases NFTs from a seller, the seller's credibility is considered to be high. Using activity may prevent sellers from fraudulently increasing their credibility.

[0035] The presentation unit 520 is a specific example of the presentation unit 12 described above. The presentation unit 520 presents the seller's credibility and a link to the seller to other users (e.g., users UB and UC). The following mainly describes the case where credibility, etc. is presented to user UB. The link is, for example, a link to a website where the seller sells items. By selecting this link, user UB can purchase the NFTed item from that site. The link may be embedded in the item.

[0036] The determination unit 530 determines whether to present the credibility and link (also referred to as credibility, etc.) based on the behavior of the user UB. For example, when the user UB views the item IA, the determination unit 530 may indicate that the item IA has been converted into an NFT using an NFT mark, etc., and may decide to present the credibility, etc., when a second user performs a selection operation (e.g., an operation to select the NFT mark).

[0037] The determination unit 530 can determine whether the user UB has viewed an item IA (e.g., an avatar) by analyzing the line of sight of the user UB. The determination unit 530 determines whether the item IA has been viewed by the user UB, for example, by analyzing whether the item IA is included in the range of the user UB's field of view or whether the line of sight of the user UB is aligned with the item IA. The determination unit 530 may also determine whether the item IA has been viewed by taking into account the results of an analysis of the user UB's pupils. The determination unit 530 determines that the item IA has been viewed when the line of sight of the user UB is aligned with the item IA and the pupils are dilated.

[0038] When user UB views item IA, the determination unit 530 displays an NFT mark around item IA or highlights the NFT mark. Alternatively, the determination unit 530 may suggest that item IA has been converted into an NFT by changing the display mode of item IA. For example, the determination unit 530 may slightly increase the size of item IA, lightly color item IA in a predetermined color, or highlight the outline of item IA. When user UB selects an NFT mark or item IA, the determination unit 530 determines to display the credibility, etc.

[0039] When user UB purchases an item, the granting unit 540 grants an incentive to user UA. This encourages each user U to use items from legitimate sellers. The granting unit 540 may display the incentive on the user terminal 100A. The incentive may be money or points that can be used in the metaverse.

[0040] FIG. 4 is a flowchart showing an example of the operation of the information processing device 1000. First, the analysis unit 510 of the item sales support server 500 analyzes the trustworthiness of the item IA (step S21). Next, the determination unit 530 of the item sales support server 500 determines whether or not to display the trustworthiness, etc., based on the behavior of the user UB (step S22). If it is determined not to display the trustworthiness, etc. (NO in step S22), the item sales support server 500 terminates the processing. If it is determined to display the trustworthiness, etc. (YES in step S22), the presentation unit 520 of the item sales support server 500 presents the trustworthiness and a link to the user UB (step S23). Next, the item sales support server 500 determines whether or not the user UB has purchased the item IA (step S24). If the user UB has purchased the item IA, the item management server 300 may notify the item sales support server 500. Alternatively, the item sales support server 500 may refer to the sales history recorded in the blockchain. If the user UB did not purchase the item IA (NO in step S24), the item sales support server 500 ends the process. If the user UB purchased the item IA (YES in step S24), the granting unit 540 of the item sales support server 500 grants an incentive to the user UA (step S25).

[0041] When the information processing device 1000 is used, the user UB can be presented with a credit rating and encouraged to purchase items from legitimate sellers. Furthermore, the user UA will use the items purchased from legitimate sellers in order to receive incentives.

[0042] FIG. 5 is a block diagram showing an example of the hardware configuration of an information processing device 1 and an item sales support server 500 (hereinafter referred to as the information processing device 1, etc.). Referring to FIG. 5, the information processing device 1, etc. includes a network interface 1001, a processor 1002, and a memory 1003.

For example, the network interface 1001 may be used for wireless LAN communication defined in the IEEE 802.11 series or mobile communication defined in 3GPP (registered trademark) (3rd Generation Partnership Project). Alternatively, the network interface 1001 may include, for example, a network interface card (NIC) conforming to the IEEE 802.3 series.

[0043] The processor 1002 reads and executes software (computer programs) from the memory 1003 to perform the processes of steps S11 to S12 in Fig. 2 and steps S21 to S25 in Fig. 4. The processor 1002 may be, for example, a microprocessor, an MPU, or a CPU. The processor 1002 may include multiple processors.

[0044] The memory 1003 is configured by a combination of volatile memory and non-volatile memory. The memory 1003 may include storage located remotely from the processor 1002. In this case, the processor 1002 may access the memory 1003 via an I / O (Input / Output) interface (not shown).

[0045] 5, the memory 1003 is used to store a group of software modules. The processor 1002 can perform the processes of steps S11 to S12 and steps S21 to S25 by reading and executing the group of software modules from the memory 1003.
