[0009] Hereinafter, the embodiments will be described in detail with reference to the attached drawings. In the attached drawings, for ease of viewing, only some of the parts having the same attribute may be labeled with reference symbols. Also, the number of each component shown in the drawings is shown as an example, and one component shown in the drawings may be composed of multiple components, or multiple components shown in the drawings may be composed of one component, depending on the attributes of each component.

[0010] (Example of hashtag system configuration) The configuration of the hashtag system 1 in this embodiment will be described.

[0011] Fig. 1a is a block diagram (part 1) showing an example of the configuration of a hashtag system 1 in this embodiment. As shown in Fig. 1a, the hashtag system 1 includes a server device 10 and a terminal device 20, which are communicatively connected to each other via a network 30. Note that, although Fig. 1a illustrates one server device 10 and two terminal devices 20, the hashtag system 1 may include multiple server devices 10 and one or three or more terminal devices 20 as necessary for the specific purpose.

[0012] Fig. 1b is a block diagram (part 2) showing an example of the configuration of the hashtag system 1. As shown in Fig. 1b, a server device 10 includes a communication unit 11, a control unit 12, and a storage unit 13. The communication unit 11 transmits and receives data to and from a terminal device 20, which is an external device, via a network 30. The form of the network 30 is not particularly limited, but when the form is the Internet, the communication unit 11 has a function of connecting to the Internet.

[0013] The control unit 12 executes various information processes and includes a CPU (Central Processing Unit) and a memory. The CPU executes an information processing program stored in the server device 10 using the memory, thereby executing various information processes. The storage unit 13 stores various data stored in the server device 10. Main examples of the various data include user information related to users and hashtag information related to registered hashtags. Note that some of the user information and hashtag information stored in the server device 10 may be manually input by the server administrator. Therefore, the server device 10 may include an input unit and an output unit (display unit) as a user interface for the server administrator to input.

[0014] Here, in this embodiment, the server device 10 is described as a single integrated configuration, but as described above, the server device 10 may be a group of multiple server devices 10 with roles divided according to functions and / or roles. For example, the server device 10 may be configured to include a data server that stores hashtag information and a service server that provides a network service, or may be configured to include a shop server that provides and charges for the products, etc. when a service is provided as part of the network service ("products, etc." means not only products but also services, the same applies below).

[0015] FIG. 1c is a block diagram (part 3) showing an example of the configuration of the hashtag system 1. As shown in FIG. 1c, the terminal device 20 includes a communication unit 21, a control unit 22, a storage unit 23, an input unit 24, and a display unit 25. The communication unit 21 transmits and receives data to and from the server device 10 via a network 30. As described above, the form of the network 30 is not particularly limited, but the communication unit 21 has a function of connecting to the Internet in the same spirit as the communication unit 11 of the server device 10. For example, the communication unit 21 may be a communication module that performs Internet communication via a wireless LAN. Alternatively, the communication unit 21 may perform communication via a mobile communication network.

[0016] The control unit 22 executes various information processes executed in the terminal device 20, and has a CPU and a memory. In the terminal device 20, the CPU executes an information processing program stored in the terminal device 20 using the memory, thereby executing various information processes. In this embodiment, the terminal device 20 stores a system program for displaying a menu image, etc., which will be described later, and a hashtag application, which is an application program for participating in the hashtag system 1 in the metaverse space. In addition to this, the terminal device 20 may store other application programs, such as a map display program and a game program, which will be described later. The CPU of the control unit 22 executes these various programs.

[0017] The storage unit 23 stores various data used in the terminal device 20. In the present embodiment, data of hash tag information received from the server 1, data of location history information to be described later, and the like are stored.

[0018] The input unit 24 receives input from a user and is an arbitrary input device such as a touch panel, a button, a stick, etc. The display unit 25 outputs various types of processed information, and the liquid crystal display may be shared with the input unit 24.

[0019] Although not shown in FIG. 1c, the terminal device 20 may further include a position detection unit that detects position information related to its own position. The form of the position detection unit is not particularly limited, but for example, the position detection unit may detect the position information using a GNSS (Global Navigation Satellite System). In this case, the position detection unit is a so-called GNSS sensor, such as a GPS (Global Positioning System) sensor. In addition, the position detection may be performed using a beacon, based on radio waves from a mobile phone base station or radio waves from a wireless access point, by detecting (calculating) the movement of the terminal device 20 using an acceleration sensor or the like, based on an image captured by a camera, based on surrounding sounds detected by a microphone, based on acquisition of information from another device different from the terminal device 20, or the like.

[0020] Although details will be described later, in the above configuration, the server device 10 stores hashtag information and provides the hashtag information to the terminal device 20. The hashtag information is displayed on a screen related to the metaverse space, and although details of the target of the hashtag will be described later, it includes not only physical objects captured in images taken in the metaverse space, but also tweets and psychological states of the objects. The hashtag information is content including images and / or sounds, and is provided by three-dimensional video, but may be still images or sound-only content depending on the user's preferences, the specifications of the terminal device 20, the situation at the time of use, and the like.

[0021] The terminal device 20 is an information processing device owned by a user who participates in the network service. In this embodiment, the terminal device 20 may be any terminal device capable of using the network service, and may be, for example, an information processing terminal such as a mobile phone, a smartphone, a tablet terminal, a PC (personal computer), a VR (virtual reality) device, a game console, or the like. The terminal device 20 is a so-called multi-function terminal, and has some of the various functions (input function, output (display) function, information processing function, network communication function, call function, camera function, etc.) that a general multi-function device has. By utilizing these functions, the terminal device 20 receives hash tag information from the server device 10 and reproduces the received hash tag information.

[0022] (Metaverse space) The hash tag system 1 is constructed in a metaverse space MV formed by the server device 10 and the terminal device 20, and an example of the metaverse space MV will be described.

[0023] The metaverse space refers to a three-dimensional virtual space and its services constructed in a computer or computer network, but in this embodiment, the metaverse space MV is formed as follows. That is, the formation of the metaverse space has progressed mainly in the field of games, but the metaverse space MV according to this embodiment is a metaverse space formed in the world of this game, with the game rules removed. Then, the remaining cyberspace is utilized as the metaverse space MV. Specifically, the main elements of the metaverse space MV as the remaining cyberspace are the character (avatar), the world (environment), and the multiplayer online function.

[0024] The metaverse space MV thus formed has spatial performance, for example, several million people connected to the space, and the number of simultaneous displays is about 50 to 100 people on a smartphone, and about 100 or more people on a PC (personal computer). However, these scales depend on the processing of the client.

[0025] As described above, the terminal device 20 for a user to participate in the metaverse space MV may be a mobile phone, a smartphone, a tablet terminal, a PC (personal computer), a VR (virtual reality) device, a game console, or the like.

[0026] The application for users to participate in the metaverse space MV may be a download version, a cloud streaming version, UE (Unreal Engine), etc.

[0027] The hashtag system 1 according to the present embodiment may be constructed as a single entity in such a metaverse space MV, or may be constructed as one system in a comprehensive metaverse system in combination with other related systems. In addition, the metaverse system may be combined with various external services as necessary. These other related systems and external services will be described later in separate sections.

[0028] (Example of applying the hashtag system) An application example of the hashtag system 1 according to the present embodiment will be described with reference to Fig. 2 to Fig. 5. Fig. 2 is a diagram for explaining an example of a photo and hashtags displayed on a screen in the metaverse space, showing the relationship between photography and hashtags, Fig. 3 similarly shows a chain hashtag that is given in a chain from multiple hashtags, Fig. 4 similarly shows a metalens that can capture things that do not exist in reality, and Fig. 5 similarly shows a rare hashtag that has a rarity in appearance.

[0029] A variety of content may be prepared in the metaverse space MV, but the hashtag system 1 can enhance searches in the metaverse space MV beyond the boundaries of such content. The hashtag system 1 is characterized by building a correspondence between photography and hashtags in a virtual trip conducted on the metaverse space MV, and the manner in which this is done is described below. The virtual trip may cover travel destinations around the world, including Japan. Note that the black silhouette of a person depicted in the figure is an image of the user corresponding to the avatar, depicted for the purposes of explaining this disclosure, and is not represented as an element depicted on the metaverse space MV. The speech bubble also represents the remarks or mental state of the user, also for the purposes of explaining this disclosure. Silhouettes of people other than the black silhouette will be explained each time.

[0030] In the hashtag system 1, a discovery is made every time a photo is taken in the metaverse space MV. That is, in the hashtag system 1, as shown in FIG. 2, when a photo is taken in the metaverse space MV, a hashtag corresponding to what is captured in the photo is automatically assigned (in this disclosure, the automatically assigned hashtag is also referred to as an "automatic tag"). Although only the automatic tag is illustrated in FIG. 2, the hashtag system 1 is not limited to the automatic tag, and in addition to or instead of the automatic tag, a hashtag that is created by the user himself and assigned manually may be provided (in this disclosure, the hashtag assigned by the user is also referred to as a "self-made tag"). When both the automatic tag and the self-made tag are provided, the hashtags are displayed so as to be distinguishable, for example, as "automatic tag: *" and "self-made tag: #".

[0031] In FIG. 2, as an example, an avatar visits the Sannai-Maruyama ruins in Aomori Prefecture as a normal virtual trip in the metaverse space MV (the meaning of "normal" will be described later). When the avatar takes a selfie with the Sannai-Maruyama ruins in the background, as shown in the upper left figure, various hashtags are displayed as shown in the upper right figure. Here, all are examples of automatic tags, and the following are displayed: "* Virtual Trip "Sannai-Maruyama Ruins"" indicating the destination of the virtual trip, "* Blue Sky" indicating the natural environment (weather), "* Solo Travel" (nature of the virtual trip), "* One-piece" (type of outfit), "* New Spring 2022" (features of outfit), "* Smartphone SP" (accessories), "* Six-pillar building" and "* Large pit dwelling" indicating the ruins visited. Note that these hashtags are merely examples and are not limited to these items and notations.

[0032] Here, a supplementary explanation will be given regarding the types of virtual trips. Although virtual trips may be classified into various types, in the present disclosure, a case where a virtual trip is classified into two types, a normal virtual trip and a premium virtual trip, is described. The normal virtual trip is assumed to be "free and easy travel around the world!" and is positioned as a mini-trip that can be easily experienced little by little every day, and may have the role of saving up funds for a premium virtual trip by visiting various places. The premium virtual trip is assumed to be "premium experience with large content!" and is positioned as a grand trip that allows you to experience famous city-sized tourist spots in their entirety for a fee, and may have the role of obtaining various extras. In the present disclosure, when there is no distinction between normal and premium, it will simply be described as a virtual trip.

[0033] When the user arrives at the destination with the avatar corresponding to himself, he takes a selfie with the thought, "I've come to the Sannai-Maruyama ruins in the normal virtual trip, so I'll take a photo to commemorate it" (see the black silhouette in the upper left of the figure). When he then looks at the photograph, he feels a kind of surprise, thinking, "There are so many hashtags!" (see the black silhouette in the upper right of the figure). This stimulates the user's interest in the next action, such as "Maybe I'll try taking a photo in other clothes," or "I wonder what kind of hashtags will be attached if I take a photo in a different place" (see the black silhouette in the lower part of the figure). In this way, the user feels that "I discovered it myself!", which stimulates his interest in "What will be in the next photo?", making exploration more fun.

[0034] In FIG. 2, an example of hashtags that are assigned individually has been described, but in addition to or instead of this, as shown in FIG. 3, in the hashtag system 1, when there is a predetermined similarity between multiple related individual hashtags, a chained hashtag that encompasses multiple individual hashtags may be assigned. In this disclosure, hashtags that are assigned in a chained manner in this manner are referred to as "series hashtags." In other words, a chained hashtag is a new hashtag that is assigned by combining an individual hashtag with another individual hashtag. The number of individual hashtags to be combined is not particularly limited as long as it is two or more.

[0035] In Fig. 3, as an example, a virtual trip in the metaverse space MV is depicted in which three avatars visit Danba in Sichuan Province in China as a group. The hashtag "*Trip of three" is displayed to indicate that it is a group of three avatars, and when multiple (here, three) hashtags are added to the costumes of each avatar according to similarities from a historical or traditional perspective, such as "*Avatar costume: Ono no Komachi," "*Avatar costume: Yang Guifei," and "*Avatar costume: Cleopatra," by combining these, an additional chain hashtag, "*Three Great Beauties in the World," is added.

[0036] The three users who see this chain hashtag (see the black silhouette of the person in the bottom right of the figure) become interested in the next action, thinking, "I wonder what will come out if I take a photo with someone wearing a monkey, a pig, and a kappa headgear on the virtual trip "Silk Road" with the three of us?" For example, in this case, they become interested in what kind of chain hashtags will be added, such as "*Son Goku / Zhu Bajie / Sha Wujing," "*Journey to the West," and "*Tanzo Hoshi." In this way, users become particular about the location of the photo and what appears in the photo, and "want to look for chain hashtags!", which makes the search more fun.

[0037] The hashtag system 1 may include a virtual lens (in this disclosure, this virtual lens is also referred to as a "metalens") that displays objects that are not visible to the naked eye and objects that do not exist in the present world (including objects that existed in the past but do not exist now) in a photo on the metaverse space MV. An example of a photo with a metalens (i.e., a photo taken through a virtual lens) is shown in FIG. 4. When an avatar takes a selfie with the Sannai-Maruyama ruins in the background, as shown in the upper left figure, if a metalens is provided, a "Jomon person making a bonfire" is displayed in the position surrounded by a dashed line (behind the avatar and under the six-pillar building) in addition to the objects in the upper right figure of FIG. 2, as shown in the upper right figure. Then, "*Jomon person" and "*bonfire" are added as hashtags and displayed. Without the virtual lens, the "Jomon people making a bonfire" would not be visible to the naked eye, but with the virtual lens, it is possible to capture objects hidden in the metaverse space MV in the photograph.

[0038] A user who owns this metalens (see the black silhouette of the person in the top left of the figure) takes a selfie as a memento of his or her acquisition of the metalens, and when they look at the photo they see a sense of surprise, saying, "...Jomon people?! A bonfire?! It wasn't in the picture last time!" (see the black silhouette of the person in the top right of the figure). This gives the user the experience of "a super scoop-level shot that could never be taken in real life!", and sparks interest in the idea that something is hiding somewhere in other scenes as well.

[0039] Here, the hidden object projected through the virtual lens may not only be a physical object, but also something like a message from the object, such as a voice from the heart. For example, as shown in the lower diagram of FIG. 4, when a photo is taken with the virtual lens attached in "Virtual Kyoto Kitano Tenmangu Shrine" as a virtual trip, the object is projected as seen with the naked eye, and the hashtag "*Komainu" is displayed, along with the hashtag "*Komainu's tweet", and the message of the Komainu with the hashtag "I want to take a photo with '*Cat Lover'" is displayed as a tweet (voice from the heart). Such a message can be applied to a means of obtaining information on how to complete a hidden mission in a game in the metaverse space MV.

[0040] The metalens may be set to be always operational, but may be limited to cases where the user (avatar) meets certain conditions in order to further enhance the interest of the hashtag system 1. For example, the metalens may be available when the user becomes accustomed to the metaverse space MV (for example, when the user's travel rank reaches a certain level or higher in the user's title system, which will be described later). By obtaining the metalens, the user can have a shooting experience that transcends reality, which is unique to the metaverse space MV, making exploration even more fun. The timing at which the metalens can be obtained may be set according to the number of days since the start of the game, the number of logins, the number of hashtags acquired, etc.

[0041] In the hashtag system 1, some or, depending on conditions, all of the hashtags may be highly rare hashtags (in this disclosure, such highly rare hashtags are also referred to as "rare hashtags"). As described above, rare hashtags may be assigned to objects captured by a metalens, such as objects that cannot be seen with the naked eye and objects that do not exist in the present world (including objects that existed in the past but no longer exist). Rare hashtags are something that users are "happy to find and happy to have," and any special benefit may be associated with them.

[0042] As shown in the top left and top center of Figure 5, rare hashtags may be set so that encounters may or may not occur at the same location depending on the timing. In this case, when the user in the top left (see the black silhouette) tells the user in the top center (see the black silhouette) "I went on a virtual trip to the Sannai-Maruyama ruins yesterday," the user in the top center will respond with "When I went, a clay figurine fell out!" The user in the top left will become interested in revisiting the Sannai-Maruyama ruins at a different time.

[0043] Also, as shown in the upper right diagram of Fig. 5, the rare hashtag may be assigned to "*Jomon-jin" when a photo is taken through the metalens (virtual lens) described above. When the user in the upper right diagram (see the black silhouette of the person) finds the rare hashtag "*Jomon-jin" in a photo he or she has taken, they rejoice, saying "Rare character, Jomon-jin!" and can boast to the two users on the left, "I took a photo with the metalens and a Jomon-jin was having a bonfire!"

[0044] In addition, as shown in the lower left diagram of Figure 5, rare hashtags may be attached to NFTs (Non-Fungible Tokens) issued or traded on the metaverse space MV. For example, when an avatar who visited Easter Island as a virtual trip took a photo, in addition to the usual hashtags of "*Moai statue" and "*Stone statue", the "Seated Maitreya Bodhisattva" set in the NFT was captured. The user (see black silhouette of person) will be delighted, saying "I bought the NFT "Seated Maitreya Bodhisattva"!" In the real world, the seated Maitreya Bodhisattva at Jionji Temple in Yamagata Prefecture is famous, but its public viewing is irregular, and in recent years it is rarely open to the public, being open to the public every 20 to 22 years. In a virtual trip, for example, when such a rare object is captured, a rare hashtag "* Seated Maitreya Bodhisattva" is added, and the only user who can possess this rare hashtag in the metaverse space MV is the owner of the NFT in question.

[0045] Rare hashtags may be added not only to NFTs corresponding to existing objects, but also to NFTs of UGC (User Generated Contents). As shown in the lower right figure of Figure 5, a user (see the black silhouette of a person) posts a message saying, "I drew this somewhere in the metaverse space MV. I will transfer the NFT rights of this art to the first person who finds it. *Banks, #savetherats." Here, the hashtags listed are "*Banks" is an example of an automatic tag, and "#savetherats" is an example of a self-made tag. In addition, the automatic tag "*umbrella rat" is added to the drawn image. In this case, the user may add a condition such as "Graffiti without an owner will be deleted after three days."

[0046] An application example of the hashtag system 1 according to this embodiment will be further described with reference to Fig. 6 to Fig. 9. Fig. 6 is a diagram for explaining communication between users in the metaverse space using hashtags, Fig. 7 is a diagram for explaining a case where advertisements are targeted by hashtags, Fig. 8 is a diagram for explaining a case where collection items are targeted by hashtags, and Fig. 9 is a diagram for explaining a case where ghost NPCs are selected / searched by automatic pop-up.

[0047] First, referring to FIG. 6, we will explain how to stimulate communication between users on the metaverse space MV using the assigned hashtag. Through communication, the value of the hashtag and, if applicable, the NFT is further increased. Here, communication between users is a concept that includes transactions between users. In addition, the hashtags that are the subject of transactions are not limited, but the following describes the case where rare hashtags with high rarity are the subject of transactions.

[0048] First, as an example, the system operator (a white silhouette of a person at a table counter) may present a mission to the user. For example, as shown in the left diagram of FIG. 6, the system operator presents a mission such as "It seems that "*Jomon people" exist in the metaverse space MV. Where is it?" to the user as a Daily Mission! The timing of presenting the mission is arbitrary, but here, an example is shown in which the mission is presented on a daily basis. Upon receiving this mission, a user (a black silhouette of a person) performs an action of "Give me a photo posted by a ghost NPC (Non-Player Character)!" and "I'll give you a "Like" as a thank you!" while showing a heart mark, and receives "*Jomon people" from the ghost NPC and completes the mission. The ghost NPC is, for example, an avatar depicted in the upper right diagram of FIG. 4. By completing this mission, the user can obtain virtual currency and virtual points.

[0049] Next, as another example, a certain user may present a mission. For example, as shown on the left side of the right diagram of FIG. 6, a certain user (black silhouette of a monk) presents a mission such as "I want to see '* Maitreya Bodhisattva Seated Statue' at least once" to other users as Mission (1)!. The other user (black silhouette) corresponding to this mission wants to clear the mission, but since there is only one person who owns the rare hashtag in the metaverse space MV, he will search in a psychological state of "Can I clear this mission?" and "Where do I go to get it?" Then, as a result of searching using a metalens or the like, the user (white silhouette) who has located the location of "* Maitreya Bodhisattva Seated Statue" responds to the certain user who presented the mission, "You can download a photo with the hashtag '* Maitreya Bodhisattva Seated Statue' from the ghost NPC ahead!" Here, the ghost NPC with the rare hashtag also becomes a rare character.

[0050] The mission presented by this user may be the same as that presented by multiple users. For example, as shown on the right side of the right diagram in FIG. 6, multiple users (silhouettes of black-colored Kokeshi dolls) present a mission to other users as Mission (2)!, asking a question such as "Users on the street are talking about it. What kind of rat is this "*Umbrella Rat"?". When the other users corresponding to this mission locate the location of "*Umbrella Rat" as a result of a search using a metalens, as in Mission (1)!, they respond to the multiple users who presented the mission with the following response: "You can download photos with the hashtag "*Umbrella Rat" from the ghost NPC ahead!"

[0051] FIG. 6 shows a case where the target of the mission is an automatic tag and a rare hashtag, but the target of the mission is not limited to this, and any combination of automatic tags and self-made tags, individual hashtags and chained hashtags, and normal hashtags and rare hashtags may be selected. Furthermore, the target of the mission may include NFTs. By combining hashtags and missions, and further by combining NFTs, communication between users on the metaverse space MV using hashtags can be stimulated, and the value of each element can be raised. As a result, value is created in the user's actions by exploring the metaverse space MV and taking photos in the metaverse space MV.

[0052] Next, referring to FIG. 7, a case where an advertisement is adopted as a target to which a hashtag is assigned will be described. For example, as shown in FIG. 7, the system operator (a white silhouette of a person at a table counter) presents a mission to a user, such as "Show me a photo with the hashtag "*Koizumigawa" as a Mission!." A consumer user (a black silhouette of a person) corresponding to this mission searches while taking photos in the metaverse space MV, wondering "Is Koizumigawa in the metaverse space MV?". When the consumer user finds the target as a result of the search, he / she responds to the system operator or the user as an advertiser, for example, "I'm here from the 5th second of the advertisement here!" Please note that FIG. 7 is drawn as an example of an advertisement for Kappan Co., a fictitious company. In the advertisement, the hashtag "*KAPPAN" indicating the advertiser, the hashtag "*Koizumigawa" indicating the person appearing in the advertisement, and the like are displayed.

[0053] This benefits advertisers because consuming users will look at the ad intently, thinking, "There might be an interesting hashtag embedded in it." Meanwhile, consuming users (black silhouettes) can earn virtual currency and virtual points by completing missions. They can also receive rewards, such as going on premium virtual trips (the meaning of "premium" will be explained later) and buying avatar costumes. As a result, advertisements that were previously only vaguely played are given value, and it is possible to provide new types of advertisements that are unique to the metaverse space MV, which make users want to see and search for them, unlike anything seen before.

[0054] Next, with reference to Fig. 8, a case where a collection item is adopted as a target to which a hashtag is assigned will be described. As shown in the upper part of Fig. 8, the collection item may be, for example, a mobility ride commemorative stamp in the metaverse space MV. Here, a case where "virtual park", "virtual mall", and "virtual Kyoto" are provided as the metaverse space MV is illustrated, and the hashtags assigned to the mobility (vehicle) stamps in each are "*virtual park: steam locomotive", "*virtual park: ferry", "*virtual park: ropeway", "*virtual mall: rooftop panda", and "*virtual Kyoto: rickshaw".

[0055] As shown in the lower left diagram of FIG. 8, when the user (black silhouette) rides a mobility in a virtual park, for example, he / she takes a photo with the collection item he / she received. Then, the hashtags "*Virtual Park" and "*Virtual Park: SL" are displayed on the photo. The collection items may be made wearable. In this way, when each collection item is collected, as shown in the lower right diagram of FIG. 8, the user (black silhouette) takes a selfie photo as if to say, "I've collected all the "Metaverse Space Mobility Ride Commemorative Stamps", so I'll take a photo to commemorate it," and the photo is given the hashtag "*Virtual Kyoto "Kitano Tenmangu Shrine"" of the location where the last collection item was added, and the hashtags given to the stamps of the five mobility vehicles (vehicles) mentioned above, as well as the hashtag "*Metaverse Space Mobility Ride Commemorative Stamp Complete" as a hashtag to confirm that the collection items have been completed. In this way, a hashtag is added to each collection item, and when a series of multiple individual collection items is collected, a complete tag is added in addition to the individual complete tags.

[0056] In this way, a hashtag is assigned to each collection item, and when all collection items are collected and a photo is taken, a "complete tag" is assigned to the collection item in addition to the hashtag for each collection item. This not only allows the user (black silhouette of a person) to rejoice that "I got the complete tag!", but also allows the user to obtain the aforementioned benefits (premium virtual trip, avatar costume, etc.) upon completing the collection.

[0057] Next, a case where a ghost NPC is selected / searched by automatic pop-up will be described with reference to Fig. 9. This is a system in which the hashtag system 1 allows the user to surf from "known" (known) information to "unknown" (unknown) information, and makes it easier to find the next "interesting" information by using hashtags.

[0058] As shown in the upper part of Fig. 9, if the location where the user (white silhouette) is currently in the metaverse space MV is "*Virtual Kyoto "Kitano Tenmangu Shrine"," a ghost NPC related to the current location is likely to appear in an automatic pop-up selection manner. Fig. 9 illustrates an example in which two photos related to a ghost NPC appear starting from the current location, Kitano Tenmangu Shrine, and the upper center of Fig. 9 shows a photo of the ghost NPC taken with Kitano Tenmangu Shrine and its lion-dog statues in the background, and the upper right side of Fig. 9 shows a photo of the ghost NPC taken with a collection of items with Kitano Tenmangu Shrine in the background. The former photo is displayed with the hashtags "*Komainu" and "*Komainu tweet" along with the message "Cat lovers, try taking a photo with this Komainu!", while the latter photo is displayed with the hashtags "*Virtual park: Ropeway," "*Virtual mall: Rooftop panda," "*Virtual park" steam locomotive," "*Virtual park: Ferry," "*Virtual Kyoto: Rickshaw," and "*Complete stamps to commemorate riding the Metaverse spatial mobility," along with the message "I've completed my collection, so take a commemorative photo!"

[0059] Here, when the user searches for "*Virtual Park:SL" as an interesting hashtag for the latter photo, the photos displaying the "*Virtual Park:SL" hashtag (the three in the bottom row of FIG. 9) are selected and displayed. Here, three types of photos are shown as examples, and in addition to the common "*Virtual Park:SL", each of them displays a different hashtag. Then, if the user finds the next "interesting" hashtag among the three photos, he or she can search for it and surf. By searching for interesting hashtags one after another through this hashtag search, the ghost NPC that is popped up changes. In this way, the user can find one "interesting" thing after another.

[0060] (Example of the title system) A title system, which will be described below, may be added to the hashtag system 1 according to the present disclosure, either inside or outside the system. Application examples of the title system according to this embodiment will be further described with reference to Fig. 10 to Fig. 12. Fig. 10 shows an overview of the title system, Fig. 11 shows a case where titles are hashtagged in the title system, and Fig. 12 shows a modified example of the title system where ghost NPCs are selected / searched by automatic pop-up.

[0061] First, an example of the assignment of titles will be described with reference to FIG. 10. For example, titles may be classified into the following eight titles as shown in FIG. 10. The following explanation will supplement the description in FIG. 10. Note that the quantities and targets shown below are merely examples and may be set arbitrarily, and may be categorized or subdivided within a certain range or type. - "Newbie Traveler": A title given to novice users who are taking part in a virtual trip for the first time. - "Wandering Traveler": A title given to users who have reached 30 "Tabibit Trunks," which indicate the number of times they have participated in virtual trips. - "Legendary Traveler": A title given to users who have reached 100 "Tabibit Trunks," which indicate the number of times they have participated in virtual trips. "Virtual Trip Expert": a title given to a user who has visited 50 locations as virtual trips. Alternatively, a user who has visited 50 premium virtual trips may be given the title "Premium Virtual Trip Expert." "Kyoto Maniac": A title given to a user who answers all questions correctly about Kyoto. As a variation, the title "(name of specific destination) Maniac" may be given to a user who is interested in a specific destination, not just Kyoto. "Cat lover": A title given to a user who has taken a photo with, for example, 10 different kinds of cats. As a variation, the title "(specific animal name) lover" may be given to a specific animal, not limited to cats. "Made 100 friends": A title given to users who have made 100 friends through the hashtag system1. - "Oshare-san": A title given to users who own 50 avatar costumes through the hashtag system 1.

[0062] By achieving each of the above conditions, users will acquire the corresponding title. The acquired title will be recorded in the user's profile. This will become one way for users to express their individuality in the metaverse space MV. For example, by combining multiple titles, users can be personalized, such as "regular," "patron," "received 1 million likes," "YamaQ fan," "at the forefront of trends," "loves to chat," and so on. And, for example, a user who has "received 1 million likes" can become the object of admiration and a goal for other users.

[0063] Next, a case where an acquired title is made into a hashtag will be described with reference to Fig. 11. For example, if a user who has answered all questions correctly in a Kyoto quiz and has acquired the title of "Kyoto Mania" takes a selfie with "Kyoto Mania" set in his / her profile, the title set in the profile will be displayed in the photo as a hashtag "*Kyoto Mania" with a title mark, as shown in Fig. 11. In this way, by making the title the subject of a hashtag, the use of the title can be diversified and the value of the title can be increased.

[0064] Next, a modified example of the selection / search by automatic pop-up of a ghost NPC will be described with reference to Fig. 12. The selection / search by automatic pop-up of a ghost NPC was described above with reference to Fig. 9, but when a title system is added, the following modification can be made. That is, when a title system is added, instead of or in addition to using the location where the user is currently located on the metaverse space MV as the starting point, a ghost NPC based on the user's attributes can be made to appear more easily by automatic pop-up.

[0065] For example, FIG. 12 shows a case where a photo of a ghost NPC with the same "title mark * novice traveler" as the user appears, starting from a hashtag indicating the user's own attribute "title mark * novice traveler". In addition to the hashtags related to the title, this photo also displays the hashtags "* Virtual Kyoto", "* Yamagami Taro", and "* Want to connect with Yama Q fans", along with the message "I wanted to meet Yama Q, so I started a metaverse space!" When a user sees this photo and finds that "* Yamagami Taro" has something in common with their interests, they can search for "* Yamagami Taro" as an interesting hashtag, and the user can find more and more "interesting" things.

[0066] (Processing in the hashtag system) Next, functional processing of the server device 10 related to the above-mentioned hash tag system 1 will be described with reference to Fig. 13. Fig. 13 is a schematic block diagram showing functions of the server device 10 related to the above-mentioned hash tag system 1.

[0067] As shown in FIG. 13, the server device 10 includes, as memory sections, an item information memory section 140, a hashtag information memory section 142, a user information memory section 144, and an avatar information memory section 146, and, as processing sections, includes a photographing section 151 (which executes the photographing step in the hashtag assignment method and the photographing function in the hashtag assignment program), a hashtag assignment section 152 (which executes the hashtag assignment step in the hashtag assignment method and the hashtag assignment function in the hashtag assignment program), and a hashtag display section 153 (which executes the hashtag display step in the hashtag assignment method and the hashtag display function in the hashtag assignment program).

[0068] Each of the storage sections, the item information storage section 140, the hashtag information storage section 142, and the avatar information storage section 146, can be realized by the storage section 13 of the server device 10 shown in Fig. 1b. Note that the settings of each of the storage sections, from the item information storage section 140 to the avatar information storage section 146, are classified by function for convenience of explanation, and as long as the same function is performed, part or all of the data stored in one storage section may be stored in another storage section.

[0069] Each of the processing sections, the photographing section 151, the hashtag assigning section 152, and the hashtag display section 153, can be realized by the control section 12 of the server device 10 shown in FIG. 1b, which appropriately cooperates with the storage section 13 and the communication section 11 and executes one or more programs in the storage section 13. As with each storage section, the settings of each processing section from the photographing section 151 to the hashtag display section 153 are classified by function for convenience of explanation, and as long as the same function is performed, some or all of the functions of one processing section may be realized by another processing section. Note that the hashtag display section 153 may be realized by the display section 25 of the terminal device 20.

[0070] Each storage section will be described. The item information storage section 140 stores item information on avatar items related to the targets of all hashtags existing in the metaverse space MV. The item information may include an item type ID and history information for each item ID. The item ID is a unique identifier given to each avatar item, and the item type ID is a unique identifier that indicates the type of avatar item. For example, if the avatar is a human incarnation, the types may be gender, age (generation), glasses, shoes, clothes, hairstyle, and accessories. The history information relates to a change history for reflecting changes in the avatar item when there is a change in the target of the hashtag due to buying and selling, model change, etc.

[0071] The hashtag information storage unit 142 stores hashtag target information for things related to destinations (visiting destinations) registered in the hashtag system 1 as hashtag targets and registered as targets of virtual trips. The hashtag target information may include a destination ID, an administrator's user ID, and hashtag target item information for each hashtag target ID. The destination ID is an identifier given to each destination in case there are multiple destinations in the hashtag system 1. The destination ID may be associated with location information of the destination in the metaverse space MV, etc. The hashtag target item information may include an item ID of the avatar item that is the hashtag target, an item type ID, etc.

[0072] The user information storage unit 144 stores user information on each consumer user who is a target of "Tabibito." The user information may include, for each user ID, a user name, a user avatar ID, information on owned items, the number of points, and user parameters, and may further include user profile information that represents the user's profile (hobbies, preferences, activities, etc.). In the hashtag system 1, the user information may be reflected in the attributes of the avatar as the consumption tendency of the user who visited the travel destination.

[0073] Details of the user information are as follows: the user ID is an ID automatically generated at the time of user registration, the user name is a name registered by each user in the hashtag system 1, and the user avatar ID is an ID representing the user avatar used by the user. The user avatar ID may be associated with avatar drawing information for drawing the user avatar. The possessed item information is various information related to avatar items associated with the user, and may include an item type ID, an item value, an item attribute, and interest information for each avatar item ID.

[0074] The item value of a possessed item is the value of an avatar item possessed by a user avatar, and may be a value correlated with the price at which it is sold in the hashtag system 1. The item attributes may represent the individuality of a product or the like that can be associated with an avatar item (e.g., color, design, functionality, decorativeness, the presence or absence of accessories, etc.). The interest information is information regarding the interest of other users in the corresponding avatar item.

[0075] The number of points indicates the number of predetermined points (an example of electronic media) that can be used to buy and sell avatar items. The predetermined points may be in the form of currency that can be used in the metaverse space MV, or in the form of cryptocurrency. The predetermined points may also be exchangeable for real currency (e.g., yen, dollars, etc.), and in this case, the exchange rate may fluctuate as appropriate. In this embodiment, in the hashtag system 1, avatar items (e.g., collection items) that are the subject of the hashtag may be bought and sold, and the number of predetermined points owned by the user avatar, i.e., information such as money owned and a planned budget, is reflected in the hashtag system 1.

[0076] The user parameters are any parameters that can be associated with a user, and may include user attributes, activity information, award history, and number of followers. The user parameters are not limited to these items and their contents, and may broadly include items that indicate the user's situation as parameters for measuring the user's popularity (recognition in the hashtag system 1 or the metaverse space MV). For example, the user avatar may experience an adventure event with a ghost NPC and may include experience points gained from the experience (for example, a quantification of knowledge gained about items and their specifications necessary or desirable for camping during the adventure).

[0077] User attributes are attributes of users in the metaverse space MV, and in addition to normal attributes, for example, special attributes may be provided that are specially given to users who are already friends with a certain ghost NPC or other users, users who have a history of purchasing an item that is the subject of a hashtag using the hashtag system 1, users with high popularity (recognition) or influence (i.e., so-called influencers), users with high status, etc. Note that popularity, influence, etc. may be correlated with the popularity, etc. of users in reality.

[0078] Activity information is a parameter (information) related to a user's activity (activity) in the metaverse space MV. The user's activity may include, for example, content distribution activity, content viewing activity, live distribution activity, and live viewing activity by the user, as well as events such as games and parties in which multiple users participate, conversations between users, and movement in the metaverse space MV, as well as events, events, and the like, which are not limited to events, events, and events, but may also include various occurrences and events. The activity information may include an adventure event in the metaverse space MV described above, as well as an experience event (such as a trial campaign) targeted by a hashtag. Specifically, the activity information may include the duration of stay, login time, and number of times in the metaverse space MV for each activity.

[0079] The prize acquisition history is historical information of the user's prize acquisition in the metaverse space MV when the event is in the form of a contest or adventure. For example, the prize acquisition history may include the prize acquisition history (number of times won, number of times won, etc.) in various contests and adventures that may be executed in the metaverse space MV. As with the above-mentioned activity information, the prize acquisition history may be collected for all users including users with normal attributes, but may be collected and managed only for users with special attributes when there is a request to reduce the processing load of the server device 10.

[0080] The number of followers indicates the number of followers for the user, and may be calculable, for example, when the user is a user who distributes various contents (for example, contents related to hashtag targets handled by the hashtag system 1), or may be calculable for all users including users who do not distribute. When users with a large number of followers visit the hashtag system 1, the hashtag system 1 itself has an advertising effect.

[0081] The avatar information storage unit 146 stores avatar drawing information for drawing user avatars and ghost NPCs. In the avatar drawing information, for each avatar ID, a face part ID, a hairstyle part ID, a costume part ID (avatar costume), etc. are associated with the avatar ID if the avatar is a human incarnation. The part information related to appearance, such as the face part ID, hairstyle part ID, and costume part ID, is a parameter that characterizes the avatar, and for the ghost NPC, it may be selected by the operator or the user who is the advertiser. For example, a plurality of types of information related to appearance, such as the face part ID, hairstyle part ID, and costume part ID, related to the ghost NPC are prepared according to gender, age (generation), the business type of the advertiser, the role of the ghost NPC, etc. In addition, when the ghost NPC is incarnated into an appearance different from a human, that is, into a real animal, an imaginary animal, various logos, a deformed costume, etc., these IDs may be adjusted according to the appearance of the ghost NPC.

[0082] The photographing unit 151 photographs the user's user avatar and the background at the travel destination (visited destination) of the virtual trip by the user by selfie. The background captured during the photographing includes buildings, scenery, and mobility (vehicles) at the travel destination. Furthermore, the photographing unit 151 can be equipped with a virtual lens (metalens), and when equipped with a virtual lens, the photographing unit 151 can capture an object that is not visible to the naked eye in the image.

[0083] The hashtag assigning unit 152 assigns a corresponding hashtag to the object captured by the photographing unit 151. As described above, when assigning a hashtag, consideration is given to whether it is an automatic tag or a self-created tag, whether it is an individual hashtag or a chained hashtag, and whether it is a normal hashtag or a rare hashtag. Furthermore, when all collection items are collected, a complete tag is assigned. Furthermore, when an NFT, advertisement, or title is applicable as a hashtag target, a hashtag is assigned to each of them.

[0084] In addition, the hashtag assigning unit 152 may function as the control unit 12 of the server device 10 to perform a mission for communicating between users in the metaverse space using hashtags, or a mission for searching for advertisements using hashtags. In addition, when selecting / searching for a ghost NPC by automatic pop-up, the hashtag assigning unit 152 may perform a function for surfing from "known" (known) information to "unknown" (unknown) information by using hashtags.

[0085] The hashtag display unit 153 associates a hashtag with the object captured by the photographing unit 151, and displays it, for example, on the display unit 25 of the terminal device 20. As described above, the hashtag is displayed with "*" for an automatic tag and with "♯" for a self-created tag. In addition, if a title system is provided, a hashtag related to a title is given a hashtag with a title mark.

[0086] Although not shown in FIG. 13, the processing department may further include a research department. The research department researches whether user satisfaction is obtained for each avatar item to be researched based on the values ​​of user parameters related to past and / or current users who own the avatar item. For example, after using the hashtag system 1, a consumer user who purchases an avatar item may be researched to see whether satisfaction is obtained with respect to the usage situation after purchase. The results of the research contribute to the analysis of whether there is an element that increases the item value of the avatar item and whether there is an element that improves the item attributes of the avatar item, as described above. The analysis results can be reflected in the contents of the hashtag, thereby contributing to the development of the hashtag system 1.

[0087] (Example of extending the hashtag system) The hashtag system 1 may be expanded as a comprehensive metaverse system by combining it with other related systems in the metaverse space. The related systems may be, for example, a role-playing game (RPG) tour system for surfing the "whole world" using an avatar costume as a trigger. The RPG tour may allow a user to experience the background story of the avatar costume by purchasing and possessing the avatar costume with the tour. For example, if a user purchases an avatar costume for a Marie Antoinette RPG tour, the user will be able to encounter historical episodes about Marie Antoinette during the virtual trip.

[0088] As described above, by constructing a comprehensive metaverse system including the hashtag system 1, it is possible to provide a variety of services related to virtual trips utilizing the metaverse space, and users can freely move around the metaverse space and obtain various benefits.
