[Figure 9] 3 is a flowchart showing a processing flow in the information processing device 1. DETAILED DESCRIPTION OF THE INVENTION

[0019] [Outline of Information Processing System S] 1 is a diagram illustrating an overview of an information processing system S according to an embodiment. The information processing system S is a system for displaying AR content. The information processing system S includes an information processing device 1, an information terminal 2, and an object 3. The object 3 includes an NFC (Near Field Communication) tag 31 and a marker 32.

[0020] The information processing device 1 is a device for managing and displaying AR content. The information processing device 1 stores the relationship between an object 3 and content to be displayed when a marker 32 attached to the object 3 is recognized.

[0021] The information terminal 2 is an information terminal 2 used by a user. The information terminal 2 is a smartphone, a tablet, or a personal computer. The information terminal 2 captures an image, recognizes a marker 32 that appears in the captured image, and displays AR content corresponding to the recognized marker 32.

[0022] The object 3 is an item to which a marker 32 is attached for displaying AR content on the information terminal 2. It is desirable that the object 3 be a portable item so that the user can have the experience of superimposing the AR content on a background photographed at any location and displaying it on the information terminal 2. One example of the object 3 is a ring, but the object 3 is not limited to this.

[0023] The object 3 is attached with an NFC tag 31. The NFC tag 31 stores item identification information (hereinafter referred to as “item ID” (Identification)). The item ID is an ID for identifying the object 3.

[0024] The processing in the information processing system S will be described. The information terminal 2 acquires an item ID ((1) in FIG. 1). The information processing device 1 acquires user identification information (hereinafter referred to as "user ID") and the item ID from the information terminal 2 that acquired the item ID ((2) in FIG. 1). The user ID is an ID for identifying the user who uses the information terminal 2.

[0025] The information processing device 1 determines whether the owner of the content corresponding to the object 3 indicated by the item ID matches the user indicated by the acquired user ID ((3) in FIG. 1).

[0026] The information processing device 1 may store the content and the content owner in association with each other, or may identify the content owner by referring to a blockchain that records the relationship between the content and the content owner.

[0027] If the owner of the content matches the user indicated by the acquired user ID, marker identification information corresponding to the acquired item ID is transmitted to the information terminal 2 ((4) in FIG. 1). The marker identification information is information for recognizing the marker 32 included in the image data captured by the information terminal 2. As an example, the marker identification information is information indicating the shape of the marker 32. The marker identification information may also include the color of the marker 32. The marker identification information is associated with a marker ID that the information terminal 2 acquires when it recognizes the marker.

[0028] The information terminal 2 captures an image of the marker 32 attached to the object 3 and recognizes the marker 32 included in the captured image data ((5) in FIG. 1). The information terminal 2 displays content corresponding to the recognized marker 32 ((6) in FIG. 1).

[0029] As an example, the information terminal 2 may acquire content corresponding to the recognized marker from the information processing device 1. Furthermore, the content to be displayed may be associated with marker identification information, and the information terminal 2 may display the content associated with the recognized marker in the marker identification information.

[0030] By configuring the information processing system S in this way, it is possible to change the content corresponding to the marker recognized by the information terminal 2 according to the user. In this way, the information processing system S can improve the flexibility in displaying AR content.

[0031] In the above example, an example was described in which the object 3 is provided with an NFC tag 31 that stores an item ID, but for example, a QR (Quick Response) code (registered trademark) with the item ID embedded therein may be provided, and the information terminal 2 may be configured to read the QR code and transmit the acquired item ID to the information processing device 1. In addition, in the above example, an example was described in which content is displayed to a content owner, but for example, the information processing system may be configured to manage a person who has received permission from the content owner to display the content, determine whether the user who sent the item ID matches the person who has received permission from the content owner to display the content, and display the content if they match.

[0032] [Configuration of information processing device 1] 2 is a block diagram showing the configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The control unit 13 has an article information acquisition unit 131, a determination unit 132, a transmission unit 133, a marker information acquisition unit 134, a display control unit 135, and an environmental information acquisition unit 136.

[0033] The communication unit 11 is a communication interface for transmitting and receiving data to and from other devices via a network. The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), a hard disk drive, etc. The storage unit 12 stores in advance a program to be executed by the control unit 13.

[0034] The storage unit 12 stores content information that associates a content ID (also referred to as "content identification information") for identifying content with an item ID that identifies an item to which a marker for displaying the content is attached. The content information may further be associated with a marker ID that identifies the marker attached to the item. FIG. 3 is a diagram showing an example of the data structure of content information stored in the storage unit 12. In the content information shown in FIG. 3(a), an "item ID", a "content ID", and a "marker ID" are associated with each other. As shown in FIG. 3(b), the content information may have different associations between the "item ID", "content ID", and "marker ID" for each user ID of the content owner.

[0035] The control unit 13 is a processor such as a CPU (Central Processing Unit), etc. The control unit 13 executes the programs stored in the storage unit 12, thereby functioning as an article information acquisition unit 131, a determination unit 132, a transmission unit 133, a marker information acquisition unit 134, a display control unit 135, and an environmental information acquisition unit 136.

[0036] The product information acquisition unit 131 acquires a user ID and a product ID from the information terminal 2 that has read the NFC tag 31.

[0037] The determination unit 132 determines whether the owner of the content corresponding to the item indicated by the item ID acquired by the item information acquisition unit 131 matches the user indicated by the user ID acquired by the item information acquisition unit 131. The determination unit 132 specifies a content ID in the content information that corresponds to the item information acquired by the item information acquisition unit 131. The determination unit 132 specifies, for example, an owner associated with the content ID acquired by the item information acquisition unit 131 in the content information.

[0038] If the determination unit 132 determines that there is a match, the transmission unit 133 transmits marker identification information for identifying the marker attached to the item to the information terminal 2. The marker identification information is associated in the content information, for example.

[0039] By configuring the information processing device 1 to transmit a marker that should be recognized in order to display content to a specific user, it becomes possible to display content targeted at the specific user.

[0040] As an example, the owner of the content may be recorded in a blockchain. Specifically, the determination unit 132 refers to a blockchain that stores content and its owner in association with each other, and determines whether the owner of the content corresponding to the item indicated by the item ID matches the user indicated by the user ID acquired by the item information acquisition unit 131. FIG. 4 is a diagram showing an example of content owner information recorded in a blockchain. The content owner information includes a content ID and an owner ID. The owner ID is a user ID indicating the owner of the content. The determination unit 132 identifies the owner of the content indicated by the identified content ID by referring to the blockchain. The determination unit 132 determines whether the identified content owner matches the user ID acquired by the item information acquisition unit 131.

[0041] By configuring the information processing device 1 to refer to the content owner information recorded in the blockchain and determine whether the owner matches, it becomes more difficult to tamper with the owner information, and it is expected that the reliability of determining whether the information matches the original owner of the content will be improved.

[0042] When the information terminal 2 recognizes the marker indicated by the marker identification information, the information processing device 1 causes the information terminal 2 to display content corresponding to the marker. Specifically, the marker information acquisition unit 134 acquires a marker ID from the information terminal 2. When the information terminal 2 recognizes a marker, it specifies the marker ID corresponding to the recognized marker and transmits it to the information processing device 1.

[0043] The display control unit 135 displays content corresponding to the marker ID on the information terminal 2. The display control unit 135 identifies content that corresponds in the content information to the marker ID acquired by the marker information acquisition unit 134, and displays the identified content on the information terminal 2. FIG. 5 is a diagram showing an example of a screen displayed by the display control unit 135. One example of the content displayed by the display control unit 135 is AR content. As one example, the display control unit 135 controls the identified content to be displayed superimposed on an image captured by the information terminal 2.

[0044] The information processing device 1 may be configured to determine whether the content owner matches when the marker is read by the information terminal 2.

[0045] The information terminal 2 captures an image of the marker 32 and recognizes the marker 32 based on the generated image data, and then transmits the marker ID and the user ID of the user using the information terminal 2 in association with each other to the information processing device 1. The marker information acquisition unit 134 acquires the marker ID and the user ID of the user using the information terminal 2 that read the marker ID in association with each other.

[0046] The determination unit 132 determines whether or not the owner of the content corresponding to the marker ID matches the user indicated by the user ID acquired by the marker information acquisition unit 134. The determination unit 132 refers to the content information and identifies the content corresponding to the marker ID acquired by the marker information acquisition unit 134. As an example, the determination unit 132 refers to a blockchain and identifies the owner of the identified content. The determination unit 132 determines whether or not the owner of the identified content matches the user indicated by the user ID acquired by the marker information acquisition unit 134.

[0047] If the content information is associated with a content owner, the determination unit 132 may refer to the content information to identify the content owner.

[0048] If the determination unit 132 determines that there is a match, the display control unit 135 causes the information terminal 2 to display the content corresponding to the marker ID. If the determination unit 132 determines that there is no match, the display control unit 135 does not cause the information terminal 2 to display the content corresponding to the marker ID. If the determination unit 132 determines that there is no match, the display control unit 135 may display a message indicating that the content is not held, or may cause the information terminal 2 to display a screen indicating a method for acquiring the content corresponding to the marker.

[0049] By configuring the information processing device 1 in this way, it becomes possible to display AR content when the content owner reads the marker.

[0050] A plurality of contents may be associated with the same marker. In this case, the information processing device 1 may be configured to display, from among the plurality of contents associated with the same marker, a content corresponding to the user who uses the information terminal 2 that read the marker.

[0051] Fig. 6 is a diagram showing an example of content information in this case. In the content information shown in Fig. 6, multiple content IDs are associated as content corresponding to the marker ID. That is, multiple contents ("C001," "C002," and "C003") are associated with one marker (for example, "M001").

[0052] When there is a plurality of contents corresponding to the marker ID, the display control unit 135 causes the information terminal 2 to display, among the contents corresponding to the marker ID, the contents owned by the user indicated by the user ID acquired by the marker information acquisition unit 134. When there is a plurality of contents corresponding in the content information to the marker ID acquired by the marker information acquisition unit 134, the determination unit 132 determines whether the owners of each of the plurality of contents match the users indicated by the user ID acquired by the marker information acquisition unit 134. The display control unit 135 causes the information terminal 2 to display, among the plurality of contents corresponding to the marker ID acquired by the marker information acquisition unit 134, the contents owned by the user corresponding to the user ID acquired by the marker information acquisition unit 134.

[0053] By configuring the information processing device 1 in this way, it becomes possible to control the markers attached to the same item so that different content is displayed depending on the user.

[0054] It is conceivable to provide a service in which a single user collects multiple pieces of content and displays the collected content. In this case, multiple pieces of content may be associated with the same marker, and the information processing device 1 may be configured to display the content when the same user owns all of the content associated with the marker.

[0055] The determination unit 132 identifies multiple content IDs corresponding to the marker IDs acquired by the marker information acquisition unit 134. The determination unit 132 identifies the owners of each of the identified multiple content IDs as described above. The determination unit 132 determines whether the owners of each of the multiple contents corresponding to the marker IDs match the users indicated by the user IDs acquired by the marker information acquisition unit 134.

[0056] The display control unit 135 displays the plurality of contents when the determination unit 132 determines that the owners of all of the plurality of contents match the user indicated by the user ID acquired by the marker information acquisition unit 134. The display control unit 135 does not display each of the plurality of contents when the determination unit 132 determines that the owner of any of the plurality of contents does not match the user indicated by the user ID acquired by the marker information acquisition unit 134. When the owner of any of the plurality of contents does not match the user indicated by the user ID, the display control unit 135 may display on the information terminal 2 a screen indicating a method for acquiring the content whose owner does not match the user indicated by the user ID acquired by the marker information acquisition unit 134.

[0057] By configuring the information processing device 1 in this way, it is possible to encourage the user to acquire content that the user does not own among a plurality of pieces of content, and as a result, it is possible to allow the user to have the experience of enjoying the process of collecting content.

[0058] The information processing device 1 may be configured to display content in a display mode that matches the external environment of the information terminal 2. In this case, the storage unit 12 stores content information that is associated with a display mode that matches the external environment of the information terminal 2. Fig. 7 is a diagram showing an example of the data structure of the content information in this case. In the content information shown in Fig. 7, the display mode of the content that matches the external environment indicated by the environmental information is associated.

[0059] The environmental information acquisition unit 136 acquires environmental information indicating the environment around the information terminal 2. The environmental information indicates, for example, the weather, temperature, humidity, or the like around the location of the information processing device 1. As an example, the environmental information acquisition unit 136 acquires location information indicating the location of the information terminal 2. The environmental information acquisition unit 136 transmits the location information of the information terminal 2 to an external server (not shown) and acquires environmental information corresponding to the location of the information terminal 2.

[0060] The display control unit 135 causes the information terminal 2 to display the content corresponding to the marker ID in a display mode based on the surrounding environment indicated by the environmental information. The display control unit 135 causes the information terminal 2 to display the content in a display mode that corresponds in the content information to the marker ID acquired by the marker information acquisition unit 134 and the environmental information acquired by the environmental information acquisition unit 136.

[0061] The environmental information may be a date or a time. In this case, the content information stores a display mode of the content corresponding to the date or time indicated by the environmental information. The information processing device 1 may also be configured to display the content in a special mode in the case of a specific location. That is, the environmental information may be the location information itself. In this case, the content information stores the location indicated by the location information and the display mode of the content in association with each other.

[0062] By configuring the information processing device 1 to display content in a display mode that corresponds to the external environment, it becomes possible to motivate the user to carry the object 3 with them when traveling.

[0063] The content may be a character, and the information processing device 1 may be configured so that the user can train the character and the content is displayed in a display mode according to the character's training status.

[0064] In this case, the content information may further be associated with a display mode according to the state of the content. One example of the state of the content is a level indicating the degree of growth of the content. For example, the state of the content changes depending on the distance or number of steps traveled by the user since acquiring the content, or the time elapsed since the user acquired the content. The state of the content may be determined depending on the degree of growth of a character represented by the content in a game using the character. The information processing device 1 may periodically acquire the state of the content from an external device.

[0065] Fig. 8 is a diagram showing an example of the data structure of the content information in this case. In the content information shown in Fig. 8, a display mode according to the state of the content is further associated.

[0066] The display control unit 135 identifies the state of the content corresponding to the marker information. As an example, the state of the content is acquired from an external server that manages the state of the content. The display control unit 135 identifies a display mode in the content information that corresponds to the marker information and the state of the content. The display control unit 135 displays the content corresponding to the marker ID in a display mode based on the state of the content indicated by the content state information.

[0067] By configuring the information processing device 1 in this way, it becomes possible for the user to enjoy the content for a long period of time, and it becomes possible to prevent the user from becoming bored with the service.

[0068] [Processing flow in information processing device 1] 9 is a flowchart showing the flow of processing in the information processing device 1. The item information acquisition unit 131 acquires an item ID and a user ID (S01). The determination unit 132 refers to content information and identifies content corresponding to the item ID (S02). The determination unit 132 identifies the owner of the identified content (S03). The determination unit 132 determines whether the owner of the content corresponding to object 3 indicated by the item ID matches the user indicated by the acquired user ID (S04).

[0069] If the owner of the content matches the user indicated by the acquired user ID (YES in S04), the transmission unit 133 transmits the marker information to the information terminal 2 (S05), and the information processing device 1 ends the process.

[0070] If the owner of the content does not match the user indicated by the acquired user ID (NO in S04), the display control unit 135 causes the information terminal 2 to display a message indicating that the acquired user ID does not match the user indicated by the acquired user ID (S06). The information processing device 1 ends the process.

[0071] [Effects of information processing device 1] The information processing device 1 is configured to transmit marker information to the information terminal 2 when the owner of the content corresponding to the item ID read from the NFC tag matches the user who read it, allowing the content to be displayed on the information terminal 2, thereby making it possible to display content targeted at a specific user.

[0072] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is "Build resilient infrastructure, promote inclusive and sustainable industrialization, and promote innovation and resilience."
