Description

【Technical Field】 【0001】 The present disclosure relates to a hashtag system, a hashtag assignment method, and a hashtag assignment program. 【Background Art】 【0002】 Regarding virtual travel in a virtual space, an object is to provide a virtual travel providing method, a virtual travel providing apparatus, a virtual travel providing program, and a virtual travel providing system that enable a user to virtually experience travel without actually going to the destination. Technologies for providing a VR space reproduction apparatus, a VR space reproduction method, a guide terminal, a guide method, an interpreter terminal, an interpretation method, and a program that can be used in such a virtual travel providing method and the like are known (for example, see Patent Document 1). 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent No. 6954716 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 However, in the above prior art, when a user (avatar) takes actions to visit various travel destinations in a virtual space, it is insufficient to ensure a free expansion regarding various things experienced at the travel destination and the correspondence with other users, and it is difficult to enhance the enjoyment of virtual travel. 【0005】 Therefore, an object of the present invention is to provide a hashtag system, a hashtag assignment method, and a hashtag assignment program that can ensure a free expansion regarding various things experienced at a travel destination and the correspondence with other users when a user conducts a virtual travel (virtual trip) in a virtual space (metaverse space). 【Means for Solving the Problems】 【0006】 One aspect of the present invention is a hashtag system in a metaverse space, comprising: a shooting unit that photographs a user and background in the metaverse space; a hashtag assignment unit that automatically assigns hashtags to objects depicted in the images captured by the shooting unit; and a hashtag display unit that displays the hashtags on a screen in association with the objects. In addition to or instead of automatically assigned hashtags, the hashtag assignment unit also assigns user-created hashtags manually at the user's discretion. [Effects of the Invention] 【0007】 According to the present invention, it is possible to provide a hashtag system, a hashtag assignment method, and a hashtag assignment program that allow for a free expansion of the correspondence between various things seen and heard at a travel destination and other users when a user takes a virtual trip in a virtual space (metaverse space).

[Figure 13] This is a schematic block diagram showing the functions of the server device in Figure 1b. [Modes for carrying out the invention] 【0009】 The embodiments will be described in detail below with reference to the attached drawings. Note that, for ease of viewing, only some of the parts with the same attribute that exist in multiple locations may be assigned reference numerals in the attached drawings. Furthermore, the number of each component shown is illustrative; depending on the attributes of each component, one component shown may be composed of multiple such components, or multiple components shown may be composed of one such component. 【0010】 (Example of a hashtag system configuration) The configuration of the hashtag system 1 in this embodiment will now be described. 【0011】 FIG. 1a is a block diagram (part 1) showing an example of the configuration of the hash tag system 1 in the present embodiment. As shown in FIG. 1a, the hash tag system 1 includes a server device 10 and a terminal device 20, and the server device 10 and the terminal device 20 are communicably connected to each other via a network 30. In FIG. 1a, one server device 10 and two terminal devices 20 are illustrated respectively, but the hash tag system 1 may include a plurality of server devices 10 and one or three or more terminal devices 20 as necessary depending on its specific use. 【0012】 FIG. 1b is a block diagram (part 2) showing an example of the configuration of the hash tag system 1. As shown in FIG. 1b, the 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 the terminal device 20 which is an external device via the network 30. The mode of the network 30 is not particularly limited, but when the mode 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 has a CPU (Central Processing Unit) and a memory. By the CPU using the memory to execute an information processing program stored in the server device 10, various information processes are executed. The storage unit 13 stores various data saved in the server device 10. Main examples of the various data include user information regarding users, hash tag information regarding registered hash tags, and the like. Note that part of the user information, hash tag information, etc. 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 perform input. 【0014】 Here, in the present embodiment, the server device 10 is described as a single integrated configuration. However, as described above, the server device 10 may be a plurality of groups of server devices 10 with divided roles according to functions and / or roles. For example, the server device 10 may have a configuration that separately includes a data server that stores hash tag information and a service server that provides network services. Alternatively, when performing a service that provides products, etc. (the term "products, etc." includes services in addition to products. The same applies hereinafter) as part of network services, the server device 10 may have a configuration that separately includes a shop server that provides products, etc. and performs billing. 【0015】 FIG. 1c is a block diagram (part 3) showing an example of the configuration of the hash tag 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 the network 30. As described, the mode of the network 30 is not particularly limited. Similar to the communication unit 11 of the server device 10, the communication unit 21 has a function of connecting to the Internet. For example, the communication unit 21 may be a communication module that performs Internet communication via a wireless LAN. In addition, the communication unit 21 may communicate 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 uses the memory to execute an information processing program stored in the terminal device 20, thereby executing various information processes. In the present embodiment, the terminal device 20 stores a system program for displaying a menu image, etc. to be described later, and a hash tag application that is an application program for participating in the hash tag system 1 in the metaverse space. In addition, other application programs such as a map display program and a game program to be described later may be stored in the terminal device 20. The CPU of the control unit 22 executes these various programs. 【0017】 The memory unit 23 stores various types of data used in the terminal device 20. In this embodiment, it stores hash tag information data received from the server 1, and location history information data, which will be described later. 【0018】 The input unit 24 accepts input from the user and can be any input device such as a touch panel, buttons, or a joystick. The display unit 25 outputs various processed information, and the liquid crystal display may be shared with the input unit 24. 【0019】 Although not shown in Figure 1c, the terminal device 20 may also include a position detection unit for detecting positional information relating to its own location. The configuration of the position detection unit is not particularly limited, but for example, the position detection unit may detect positional information using 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. Other possible methods include position detection using beacons, position detection based on radio waves from mobile phone base stations or wireless access points, position detection (calculation) by detecting the movement of the terminal device 20 using an acceleration sensor, position detection based on images captured by a camera, position detection based on ambient sound detected by a microphone, and position detection based on information obtained from other devices different from the terminal device 20. 【0020】 As will be explained in more detail later, in the above configuration, the server device 10 stores hashtag information and provides it to the terminal device 20. The hashtag information is displayed on the screen related to the metaverse space, and although the details of the hashtag targets will be described later, it includes not only physical objects captured in images taken in the metaverse space, but also the tweets and psychological states of the objects captured. The hashtag information is content including images and / or sound, and is provided as a 3D video, but it may also be a still image or sound-only content depending on the user's preferences, the specifications of the terminal device 20, and the circumstances of use. 【0021】 Terminal device 20 is an information processing device owned by a user participating in the network service. In this embodiment, terminal device 20 can be any terminal device capable of using the network service, such as a mobile phone, smartphone, tablet, PC (personal computer), VR (virtual reality) device, or game console. Furthermore, terminal device 20 is a so-called multifunction terminal and possesses several of the various functions (input function, output (display) function, information processing function, network communication function, call function, camera function, etc.) that a typical multifunction device has. Utilizing these functions, terminal device 20 receives hashtag information from server device 10 and plays back the received hashtag information. 【0022】 (Metaverse space) The hashtag system 1 is constructed within a metaverse space MV formed by the server device 10 and terminal devices 20. An example of the metaverse space MV will be explained below. 【0023】 The metaverse space refers to a three-dimensional virtual space and its services built within a computer or computer network. In this embodiment, the metaverse space MV is formed as follows. That is, while the formation of the metaverse space has mainly progressed in the field of games, the metaverse space MV according to this embodiment is created by removing the rules of the game from the metaverse space formed in the world of a game. The remaining cyberspace is then utilized as the metaverse space MV. Specifically, the main elements of this remaining cyberspace metaverse space MV are characters (avatars), the world (environment), and multiplayer online functionality. 【0024】 The metaverse space (MV) formed in this way has spatial performance capabilities such as handling several million connected users and simultaneously displaying content for 50-100 people on smartphones and over 100 people on PCs (personal computers). However, these scales depend on the client's processing power. 【0025】 As mentioned above, the terminal device 20 for a user to participate in the metaverse space MV may be a mobile phone, smartphone, tablet device, PC (personal computer), VR (virtual reality) device, game console, etc. 【0026】 Applications that allow users to participate in the metaverse space (MV) may use downloadable versions, cloud streaming versions, or Unreal Engine (UE), etc. 【0027】 The hashtag system 1 according to this embodiment may be constructed as a standalone entity within such a metaverse space MV, or it may be constructed as one system within a comprehensive metaverse system in combination with other related systems. Furthermore, the metaverse system may be combined with various external services as needed. These other related systems and external services will be described in a separate section later. 【0028】 (Examples of hashtag system applications) Referencing Figures 2 to 5, an example of the application of the hashtag system 1 according to this embodiment will be described. Figure 2 is a diagram illustrating an example of a photograph and hashtags displayed on a screen in the metaverse space, showing the relationship between photography and hashtags; Figure 3 similarly shows chain hashtags that are sequentially added from multiple hashtags; Figure 4 similarly shows a metalens that can photograph things that do not exist in reality; and Figure 5 similarly shows rare hashtags that have rarity in appearance. 【0029】 While various types of content may be available in the metaverse space MV, hashtag system 1 can enhance exploration within the metaverse space MV by transcending the boundaries of that content. Hashtag system 1 is characterized by establishing a correspondence between photographs and hashtags during virtual trips conducted in the metaverse space MV, and its manifestation is described below. Virtual trips may cover travel destinations around the world, including within Japan. Note that the black silhouettes of people depicted in the figures are images of users corresponding to avatars, drawn for the purpose of explaining this disclosure, and do not represent elements drawn on the metaverse space MV. The speech bubbles also represent the user's statements or psychological state, also for the purpose of explaining this disclosure. Other silhouettes of people will be explained as needed. 【0030】 In hashtag system 1, a discovery is made each time a photograph is taken in the metaverse space MV. That is, in hashtag system 1, as shown in Figure 2, when a photograph is taken in the metaverse space MV, hashtags corresponding to what is captured in the photograph are automatically added (in this disclosure, automatically added hashtags are also referred to as "automatic tags"). Although only automatic tags are illustrated in Figure 2, hashtag system 1 is not limited to automatic tags, and in addition to or instead of automatic tags, users may also provide hashtags that they create themselves and add manually (in this disclosure, user-created hashtags are also referred to as "user-created tags"). If both automatic tags and user-created tags are provided, the hashtags are displayed in a way that allows them to be distinguished, for example, "automatic tag:*" and "user-created tag:#". 【0031】 Figure 2 illustrates, as an example, a normal virtual trip within the metaverse space MV (the meaning of "normal" will be explained later), where an avatar visits the Sannai-Maruyama Ruins in Aomori Prefecture. When the avatar takes a selfie with the Sannai-Maruyama Ruins as 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 automatically generated tags, including "*Virtual Trip "Sannai-Maruyama Ruins"" indicating the destination of the virtual trip, "*Blue Sky" indicating the natural environment (weather), "*Solo Trip" (nature of the virtual trip), "*One Piece" (type of outfit), "*New Spring 2022" (characteristics of the outfit), "*Smartphone SP" (accessory), and "*Six-Pillar Building" and "*Large Pit Dwelling" indicating the visited ruins. Note that these hashtags are merely examples and are not limited to these items and their content. 【0032】 Here, we will provide some additional information regarding the types of virtual trips. While virtual trips can be categorized into various types, this disclosure explains the distinction between normal virtual trips and premium virtual trips. Normal virtual trips are envisioned as "free and easy world travel!" and are positioned as short, easy-to-experience mini-trips that can be enjoyed a little bit each day. They may also serve the purpose of accumulating funds for premium virtual trips by visiting various places. Premium virtual trips are envisioned as "premium experiences with large-scale content!" and are positioned as grand trips that allow users to experience entire famous tourist destinations on a city scale for a fee. They may also serve the purpose of providing various bonuses. In this disclosure, when the distinction between normal and premium is not made, they are simply referred to as virtual trips. 【0033】 When a user arrives at a destination with their corresponding avatar, they take a selfie, as if to say, "I've arrived at the Sannai-Maruyama Ruins on a normal virtual trip, so let's take a commemorative photo" (see the black silhouette of a person in the upper left of the diagram). Upon seeing the photo, they are surprised to see that "lots of hashtags have been added!" (see the black silhouette of a person in the upper right of the diagram). This sparks interest in taking the next step, such as "Maybe I should try taking a photo in other clothes," or "What kind of hashtags will I get if I take a photo in a different location?" (see the black silhouette of a person in the lower of the diagram). In this way, the feeling of "I discovered it myself!" sparks curiosity about "What will be in the next photo?", making exploration more enjoyable. 【0034】 Figure 2 illustrates examples of individually assigned hashtags. However, in addition to or instead of this, hashtag system 1 may assign a chained hashtag encompassing multiple individual hashtags when there is a predetermined similarity between them, as shown in Figure 3. In this disclosure, hashtags assigned in this chained manner are referred to as "chained hashtags." In other words, a chained hashtag is a hashtag newly assigned by combining one individual hashtag with another individual hashtag. The number of individual hashtags to be combined is not particularly limited, as long as there are two or more. 【0035】 Figure 3 illustrates, as an example, a virtual trip within the metaverse space MV, where three avatars visit Danba, Sichuan Province, China, as a group. The hashtag "*Three-Person Trip" is displayed to indicate that it is a group of three avatars, and if multiple (in this case, three) hashtags are added to each avatar's costume based on historical or traditional similarities, such as "*Avatar Costume: Ono no Komachi", "*Avatar Costume: Yang Guifei", and "*Avatar Costume: Cleopatra", then combining these hashtags results in the chain hashtag "*World's Three Great Beauties". 【0036】 Three users who see this chain of hashtags (see the black silhouette of the person in the lower right of the diagram) are intrigued by the idea of ​​taking the next step, such as, "What would happen if I took a photo with two other people, each wearing a monkey, a pig, and a kappa mask, on a virtual trip to the 'Silk Road'?" For example, in this case, they become interested in what kind of chain hashtags would be added, such as "*Sun Wukong / Zhu Bajie / Sha Wujing", "*Journey to the West", and "*Tripitaka". In this way, users become interested in the location of the photo and what appears in the photo, and the search becomes fun because they "want to find chain hashtags!" 【0037】 Hashtag System 1 may include a virtual lens (in this disclosure, this virtual lens is also referred to as a "meta-lens") that projects subjects that are not visible to the naked eye, and subjects that do not exist in the present world (including those that existed in the past but no longer exist) onto photographs in the metaverse space MV. An example of a photograph with a meta-lens (i.e., a photograph taken through a virtual lens) is shown in Figure 4. When an avatar takes a selfie with the Sannai-Maruyama site as the background, as shown in the upper left figure, if a meta-lens is included, as shown in the upper right figure, in addition to the subject in the upper right figure of Figure 2, a "Jomon person making a bonfire" will be projected at the location enclosed by the dashed line (behind the avatar and below the six-pillar building). The hashtags "*Jomon person" and "*bonfire" will then be added and displayed. Without a virtual lens, the "Jomon people making a bonfire" cannot be seen with the naked eye, but by equipping a virtual lens, it becomes possible to capture objects hidden in the metaverse space (MV) in a photograph. 【0038】 A user who possesses this MetaLens (see the black silhouette of a person in the upper left of the diagram) takes a selfie, thinking, "I've got a MetaLens, so I'll take a commemorative photo." Upon seeing the photo, they are surprised, thinking, "...A Jomon person!? A bonfire!? They didn't show up last time!" (see the black silhouette of a person in the upper right of the diagram). This gives the user the experience of having captured a "super scoop-worthy photo that could never be taken in reality!" and sparks their interest in other scenes as well, wondering if something is hidden somewhere. 【0039】 Here, the hidden subject captured through the virtual lens may not only be a physical object, but also something like a voice of the heart, a message from the subject. For example, as shown in the lower part of Figure 4, in the virtual trip "Virtual Kyoto 'Kitano Tenmangu Shrine'", when a photograph is taken with the virtual lens equipped, the guardian lion-dogs are captured as they appear to the naked eye, the hashtag "*guardian lion-dogs" is displayed, along with the hashtag "*guardian lion-dog's tweet", and the message from the guardian lion-dog with the hashtag "I want to take a picture with a "*cat lover"" is displayed as a tweet (voice of the heart). Such messages can be applied to a game in the metaverse space MV, for example, to obtain information on how to complete a hidden mission. 【0040】 Metalenses may be set up permanently and available for use at any time, but to further enhance the appeal of hashtag system 1, they may be limited to users (avatars) who meet certain conditions. For example, Metalenses may be obtainable when a user becomes familiar with the metaverse space MV (for example, when their Tabibito rank in the user title system described later reaches a certain level). Obtaining Metalenses allows for a unique, transcendent photography experience only possible in the metaverse space MV, making exploration more enjoyable. The timing for obtaining Metalenses may be set based on factors such as the number of days since the start of the game, the number of logins, and the number of hashtags acquired. 【0041】 In hashtag system 1, some or all of the hashtags may be designated as rare hashtags (in this disclosure, these rare hashtags are also referred to as "rare hashtags"). As mentioned above, rare hashtags may be assigned to subjects that appear as if they were captured by a metalens, for example, subjects that are not visible to the naked eye, or subjects that do not exist in the present world (including those that existed in the past but no longer exist). Rare hashtags are something that users will be happy to find and happy to possess, and may be associated with optional rewards. 【0042】 Rare hashtags can be set up so that encounters may or may not occur depending on the timing, even in the same location, as shown in the upper left and upper center diagrams of Figure 5. In this case, if the user in the upper left diagram (see silhouette of blacked-out person) tells the user in the upper center diagram (see silhouette of blacked-out person) "I took a virtual trip to the Sannai-Maruyama site yesterday," the user in the upper center diagram might respond with "When I was there, a clay figurine was lying around!" This would make the user in the upper left diagram interested in revisiting the Sannai-Maruyama site at a different time. 【0043】 Furthermore, as shown in the upper right diagram of Figure 5, the rare hashtag may also be applied to "*Jomon people" when photographed through the aforementioned metalens (virtual lens). When the user in the upper right diagram (see the black silhouette of the person) discovers the rare hashtag "*Jomon people" in a photograph they have taken, they rejoice, saying "Rare character, Jomon people!" and can boast to the two users on the left, "I took a picture with the metalens and there were Jomon people making a bonfire!" 【0044】 In addition, as shown in the lower left diagram of Figure 5, rare hashtags may also be attached to NFTs (Non-Fungible Tokens) issued or traded on the metaverse space MV. For example, suppose an avatar visiting Easter Island as a virtual trip takes a photo, and in addition to the usual hashtags "*Moai statue" and "*Stone statue," the NFT "Maitreya Bodhisattva seated statue" is also captured in the image. The user (see silhouette of a person in black) would rejoice, "I bought the NFT 'Maitreya Bodhisattva seated statue'!" In the real world, the Maitreya Bodhisattva seated statue at Jionji Temple in Yamagata Prefecture is famous, but its public viewing is infrequent, and in recent years it has only been displayed every 20 to 22 years, making it quite difficult to see. In a virtual trip, for example, when a highly rare subject like this is captured, a rare hashtag such as "*Maitreya Bodhisattva seated statue" is added, and only the owner of the NFT in question can possess this rare hashtag in the metaverse space MV. 【0045】 Rare hashtags can be attached not only to NFTs corresponding to existing subjects, but also to NFTs of UGC (User Generated Content). As shown in the lower right of Figure 5, a user (see silhouette of a person in black) posts the message, "I drew this somewhere in the metaverse space MV. I will transfer the NFT rights to this art to the first person who finds it. *Banks, #SaveTheRats." Here, the hashtags listed, "*Banks" and "#SaveTheRats," are examples of automatically generated tags and user-created tags, respectively. The image itself is automatically tagged with "*UmbrellaRat." In this case, the user may also add conditions such as, "I will delete ownerless graffiti after 3 days." 【0046】 Referencing Figures 6 to 9, examples of how the hashtag system 1 according to this embodiment can be applied will be further explained. Figure 6 illustrates communication between users in a metaverse space using hashtags, Figure 7 illustrates the case where advertisements are the target of hashtags, Figure 8 illustrates the case where collection items are the target of hashtags, and Figure 9 illustrates the case where ghost NPCs are automatically selected / searched. 【0047】 First, referring to Figure 6, we will explain how the assigned hashtags stimulate communication between users in the metaverse space (MV). Through this communication, the value of the hashtags, and in the case of NFTs, is further enhanced. Here, communication between users includes transactions between users. While there are no limitations on the hashtags that can be traded, the following explanation will focus on the case where rare hashtags with high scarcity are the target of trading. 【0048】 First, as an example, the system operator (a white silhouette of a person at the table counter) could present missions to users. For example, as shown in the left diagram of Figure 6, the system operator could present a mission to the user as a Daily Mission! such as, "It seems there's a '*Jomon person' in the metaverse space MV. I wonder where they are?" The timing of presenting the mission is arbitrary, but here we show an example of presenting the mission on a daily basis. Upon receiving this mission, a user (a black silhouette of a person) would perform the actions of, "Please give me the photo posted on the Ghost NPC (Non-Player Character)!" and, while showing a heart symbol, "I'll give you a 'like' as a thank you!", thereby receiving the "*Jomon person" from the Ghost NPC and completing the mission. The Ghost NPC is, for example, the avatar depicted in the upper right diagram of Figure 4. By completing this mission, the user can obtain virtual currency or virtual points. 【0049】 Next, as another example, a user could present a mission. For example, as shown on the left side of the right-hand diagram in Figure 6, a user (a black silhouette of a monk) presents a mission to other users as Mission (1)!, such as, "I want to see the *Maitreya Bodhisattva statue at least once." The other user (a black silhouette) responding to this mission wants to complete it, but since the owner of the rare hashtag is only one person in the metaverse space MV, they will explore with the psychological state of "Can I complete this mission?" and "Where can I get it?". As a result of their search using MetaLens and other tools, the user (a white silhouette) who locates the *Maitreya Bodhisattva statue will respond to the user who presented the mission by saying, "You can download a photo with the *Maitreya Bodhisattva statue hashtag from a ghost NPC up 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 mission presented by multiple users. For example, as shown on the right side of the right diagram in Figure 6, multiple users (silhouettes of black kokeshi dolls) present a mission to other users as Mission (2)!, posing a question such as, "Users passing by are talking about it. What kind of rat is this '*Umbrella Rat'?" Other users responding to this mission, similar to Mission (1)!, will use their search skills, such as Metalens, to locate the "*Umbrella Rat" and then inform the multiple users who presented the mission, "You can download a photo with the hashtag '*Umbrella Rat' from the ghost NPC up ahead!" 【0051】 Figure 6 shows a case where the mission targets both automated tags and rare hashtags, but the mission targets are not limited to this. Users may choose any combination of automated tags and user-created tags, individual hashtags and chained hashtags, and regular hashtags and rare hashtags. Furthermore, NFTs may also be included as targets of the mission. By combining hashtags and missions, and even more so by combining them with NFTs, it is possible to stimulate communication between users on the metaverse space MV using hashtags and enhance the value of each element. As a result, value is created in user actions such as exploring the metaverse space MV and taking photos on the metaverse space MV. 【0052】 Next, referring to Figure 7, we will explain the case where advertisements are used as the target for hashtagging. For example, as shown in Figure 7, the system operator (white silhouette of a person on the table counter) presents a mission to the user, such as "Show me a photo with the hashtag "*Koizumigawa". The consumer user (black silhouette of a person) responding to this mission searches the metaverse space MV, taking photos, while wondering, "Was Koizumigawa in the metaverse space MV?" If the consumer user finds the target as a result of their search, they respond to the system operator or the advertiser user, for example, "He's in this ad from 5 seconds in!". Note that Figure 7 is an example illustration of an advertisement for a fictional company, Kappan Inc. The advertisement displays hashtags such as "*KAPPAN" indicating the advertiser and "*Koizumigawa" indicating the person appearing in the advertisement. 【0053】 This allows advertisers to benefit from the fact that consumers will eagerly scrutinize their ads, thinking, "There might be an interesting hashtag embedded in this." Meanwhile, consumers (black silhouettes of people) can earn virtual currency and virtual points by completing missions. They can then earn perks such as going on premium virtual trips (the meaning of "premium" will be explained later) or purchasing avatar costumes. As a result, ads that were previously just played passively are given value, allowing for the creation of new and unique advertisements that are appealing and desirable, characteristic of the metaverse space MV. 【0054】 Next, referring to Figure 8, we will explain the case where collection items are used as the target for hashtags. As shown in the upper part of Figure 8, collection items may be, for example, stamps commemorating rides on mobility in the metaverse space MV. Here, we illustrate the case where "Virtual Park," "Virtual Mall," and "Virtual Kyoto" are provided as metaverse spaces MV, and the hashtags attached to the mobility (vehicle) stamps in each are "*Virtual Park:SL," "*Virtual Park:Ferry," "*Virtual Park:Cableway," "*Virtual Mall:Rooftop Panda," and "*Virtual Kyoto:Rickshaw." 【0055】 As shown in the lower left of Figure 8, the user (black silhouette) can take a photo with the collected items they received when, for example, riding a mobility device in the virtual park. The hashtags "*Virtual Park" and "*Virtual Park:SL" will then appear on the photo. The collected items may also be wearable. When all the collected items are collected, as shown in the lower right of Figure 8, the user (black silhouette) can take a selfie as if to say, "I've collected all the 'Metaverse Space Mobility Ride Commemorative Stamps,' so here's a commemorative photo." The photo will then be tagged with the hashtag of the location where the last collected item was attached, "*Virtual Kyoto 'Kitano Tenmangu Shrine'," along with the hashtags attached to the five mobility (vehicle) stamps mentioned above, and the hashtag "*Metaverse Space Mobility Ride Commemorative Stamp Complete" to confirm that the collection items have been completed. In this way, hashtags are attached to individual collection items, and when a series of multiple individual collection items are collected, a complete tag is attached in addition to the individual complete tags. 【0056】 In this way, each collection item is assigned a hashtag, and when all collection items are gathered and a photo is taken, in addition to the hashtags for each collection item, a special hashtag called the "Complete Tag" is added. This allows the user (black silhouette) to rejoice with "I got the Complete Tag!", and upon completion, they may receive the aforementioned rewards (such as a premium virtual trip or avatar costume). 【0057】 Next, referring to Figure 9, we will explain how to automatically select / search for ghost NPCs. In hashtag system 1, this allows users to surf to unknown information starting from information they "know," and makes it easier to encounter the next thing that "interests" them using hashtags. 【0058】 As shown in the upper part of Figure 9, if the user (white silhouette) is currently located in the metaverse space MV as "*Virtual Kyoto "Kitano Tenmangu Shrine", then ghost NPCs related to the current location are more likely to appear in the automatic pop selection mode. Figure 9 illustrates the case where two photos related to ghost NPCs appear, starting from Kitano Tenmangu Shrine, the current location. In the upper center of Figure 9, a photo of the ghost NPC taken with Kitano Tenmangu Shrine and its guardian lion-dogs in the background is shown, and in the upper right of Figure 9, a photo of the ghost NPC taken with Kitano Tenmangu Shrine in the background along with the collected items is shown. The former photo displays the hashtags "*Komainu" and "*Komainu's Tweets" along with the message, "If you're a cat lover, try taking a photo with this Komainu!" The latter photo displays the hashtags "*Virtual Park: Ropeway", "*Virtual Mall: Rooftop Panda", "*Virtual Park: Steam Locomotive", "*Virtual Park: Ferry", "*Virtual Kyoto: Rickshaw", and "*Metaverse Space Mobility Ride Commemorative Stamp Complete" along with the message, "I've collected them all, so here's a commemorative photo!" 【0059】 Here, if a user searches for the hashtag "*Virtual Park:SL" on the latter photo, the photos displaying the hashtag "*Virtual Park:SL" (the three photos in the lower row of Figure 9) will be selected and displayed. Three types of photos are shown as examples here, and in addition to the common hashtag "*Virtual Park:SL", each of them displays different hashtags. The user can then search for and surf through the three photos to find the next hashtag that interests them. As the user searches for interesting hashtags one after another, the ghost NPCs that pop up will change. In this way, the user can find one interesting thing after another. 【0060】 (Example of application of the title system) The hashtag system 1 relating to this disclosure may have a title system, as described below, added to it either inside or outside the system. An example of the application of the title system according to this embodiment will be further described with reference to Figures 10 to 12. Figure 10 shows an overview of the title system, Figure 11 shows a case where titles are hashtagged in the title system, and Figure 12 shows a modified example where titles are selected / searched using automatic pop-ups of ghost NPCs in the title system. 【0061】 First, an example of assigning titles will be explained with reference to Figure 10. For example, titles may be divided into eight categories as shown in Figure 10. The following explanation will supplement the description in Figure 10. Note that the quantities and subjects shown below are merely examples and can be set arbitrarily, and categorization and subdivision may be carried out within a certain range or type. • "Rookie Traveler": A title given to users who are participating in a virtual trip for the first time, essentially beginner users. • "Wandering Traveler": A title awarded to users who reach 30 "Traveler Ranks," which indicate the number of times they have participated in virtual trips. • "Legendary Traveler": A title awarded to users who reach 100 "Traveler Ranks," which indicate the number of times they have participated in virtual trips. • "Virtual Trip Master": A title awarded to users who have visited 50 locations as virtual trips. As an alternative, users who have visited 50 premium virtual trips may be awarded the title "Premium Virtual Trip Master." • "Kyoto Mania": A title awarded to users who correctly answer all questions in a Kyoto quiz. As a variation, the title could be given to a specific travel destination, such as "(Name of a specific travel destination) Mania," rather than Kyoto. • "Cat Lover": A title given to a user who has taken photos with, for example, 10 different types of cats. As an alternative, the title could be given to a specific animal, such as "(Name of a specific animal) Lover," rather than just cats. • "Made 100 Friends": A title awarded to users who have become friends with 100 people through the hashtag system 1. • "Stylish Person": A title awarded to users who possess 50 avatar outfits through the hashtag system 1. 【0062】 Users earn corresponding titles by fulfilling each of the conditions described above. The earned titles are recorded in the user's profile. This becomes one way for users to express their individuality in the metaverse space MV. For example, by combining multiple titles, users can be characterized as "regulars," "patrons," "have received 1 million likes," "YamaQ fans," "trendsetting," "talkative," etc. And, for example, a user who has received "1 million likes" can become an object of admiration and a goal for other users. 【0063】 Next, referring to Figure 11, we will explain how to turn acquired titles into hashtags. For example, if a user who has answered all questions correctly in a Kyoto quiz and earned the title of "Kyoto Mania" takes a selfie with "Kyoto Mania" set in their profile, the title set in their profile will appear in the photo as a hashtag "*Kyoto Mania" with the title mark, as shown in Figure 11. In this way, by making titles eligible for hashtags, the uses of titles can be diversified and their value can be increased. 【0064】 Next, referring to Figure 12, we will explain a modified version of the automatic selection / search for ghost NPCs. Earlier, referring to Figure 9, we explained the automatic selection / search for ghost NPCs, but when a title system is added, it can be modified as follows. That is, when a title system is added, instead of using the user's current location in the metaverse space MV as the starting point, or in addition to that, it is possible to make it easier for ghost NPCs to appear automatically based on the user's attributes. 【0065】 For example, Figure 12 shows a case where a user's hashtag, "Beginner Traveler with Title Mark," is used as a starting point to find a photo of a ghost NPC that has the same "Beginner Traveler with Title Mark" attribute as the user. In addition to the hashtag related to the title, this photo displays the hashtags "*Virtual Kyoto," "*Taro Yamagami," and "*Want to connect with other YamaQ fans," along with the message, "I started a metaverse space because I wanted to meet YamaQ!" When a user sees this photo and finds that "*Taro Yamagami" is something they are interested in, they can search for "*Taro Yamagami" as a hashtag of interest, and in doing so, the user can find one thing after another that interests them. 【0066】 (Processing in hashtag systems) Next, with reference to Figure 13, the functional processing of the server device 10 related to the hashtag system 1 described above will be explained. Figure 13 is a schematic block diagram showing the functions of the server device 10 related to the hashtag system 1 described above. 【0067】 As shown in Figure 13, the server device 10 includes, as a storage unit, an item information storage unit 140, a hashtag information storage unit 142, a user information storage unit 144, and an avatar information storage unit 146, and as a processing unit, a shooting unit 151 (which performs the shooting step in the hashtag assignment method and the shooting function in the hashtag assignment program), a hashtag assignment unit 152 (which performs the hashtag assignment step in the hashtag assignment method and the hashtag assignment function in the hashtag assignment program), and a hashtag display unit 153 (which performs the hashtag display step in the hashtag assignment method and the hashtag display function in the hashtag assignment program). 【0068】 The item information storage unit 140, the hashtag information storage unit 142, and the avatar information storage unit 146 can be realized by the storage unit 13 of the server device 10 shown in Figure 1b. The settings for each storage unit from the item information storage unit 140 to the avatar information storage unit 146 are classified by function for the sake of explanation, and some or all of the data stored in one storage unit may be stored in another storage unit as long as similar functions are operating. 【0069】 Each processing unit, the shooting unit 151, the hashtag assignment unit 152, and the hashtag display unit 153, can be implemented by the control unit 12 of the server device 10 shown in Figure 1b, which, as appropriate, cooperates with the storage unit 13 and the communication unit 11 to execute one or more programs in the storage unit 13. Similar to the storage units, the settings for each processing unit from the shooting unit 151 to the hashtag display unit 153 are classified by function for the sake of explanation, and if similar functions are performed, some or all of the functions of one processing unit may be implemented by other processing units. In addition, the hashtag display unit 153 may be implemented by the display unit 25 of the terminal device 20. 【0070】 Let's explain each memory section. The item information memory unit 140 stores item information for all avatar items related to hashtags that exist 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 assigned to each avatar item, and the item type ID is a unique identifier representing the type of avatar item. For example, if the avatar is a human being, the type may be gender, age (generation), glasses, shoes, clothing, hairstyle, accessories, etc. The history information concerns the change history for reflecting changes in the avatar item when there are changes to the target of the hashtag due to buying and selling, model changes, etc. 【0071】 The hashtag information storage unit 142 stores hashtag target information for things related to travel destinations (places to visit) that are registered as targets for hashtags in the hashtag system 1 and as targets for virtual trips. The hashtag target information may include a travel destination ID, the administrator's user ID, and hashtag target item information for each hashtag target ID. The travel destination ID is an identifier assigned to each travel destination in the hashtag system 1 to accommodate cases where there are multiple travel destinations. The travel destination ID may be associated with location information of the travel destination in the metaverse space MV. The hashtag target item information may include the item ID of the avatar item that is the target of the hashtag, the item type ID, etc. 【0072】 The user information storage unit 144 stores user information for each consumer user targeted by "Tabibito". User information may include, for each user ID, the username, user avatar ID, owned item information, number of points, and user parameters, and may also include user profile information representing the user's profile (hobbies, preferences, activities, etc.). In the hashtag system 1, user information can be reflected in the avatar attributes as the consumption tendencies of users who have visited a travel destination. 【0073】 The details of user information are as follows: User ID is an ID automatically generated at the time of user registration, username is the name that each user registers with hashtag system 1, and user avatar ID is an ID that represents the user avatar used by the user. Avatar rendering information for rendering the user avatar may be associated with the user avatar ID. Possessed item information is various information about the avatar items associated with the user, and for each avatar item ID, it may include item type ID, item value, item attributes, and interest information. 【0074】 The item value related to possessed items is the value of the avatar items possessed by the user avatar, and may be a value correlated with the price at which they are sold using hashtag system 1. Item attributes may represent the individuality of products, etc., that can be associated with avatar items (e.g., color, design, functionality, ornamentation, presence or absence of accessories, etc.). Interest information is information about other users' interest in the corresponding avatar item. 【0075】 The number of points represents the number of predetermined points (an example of an electronic medium) that can be used to buy and sell avatar items. The predetermined points may be in the form of currency usable within the metaverse space MV, or in the form of cryptocurrency. Furthermore, the predetermined points may be exchangeable for real-world currency (e.g., yen or dollars), and the exchange rate in this case may fluctuate as appropriate. In this embodiment, avatar items targeted by hashtags (e.g., collection items) may be bought and sold in the hashtag system 1, and the number of predetermined points held by the user avatar, i.e., information such as the amount of money held or the budget being considered, is reflected in the hashtag system 1. 【0076】 User parameters are any parameters that can be associated with a user and may include user attributes, activity information, award history, and follower count. User parameters are not limited to these items and their contents, and may broadly include items that indicate the user's situation as parameters that measure the user's popularity (recognition within the hashtag system 1 or the metaverse space MV). For example, it may include experience points gained when a user avatar experiences an adventure event with a ghost NPC (for example, a numerical representation of the knowledge gained about necessary or desirable items and their specifications for camping with the ghost NPC during the adventure). 【0077】 User attributes are the attributes of a user within the metaverse space MV. For example, in addition to normal attributes, special attributes may be provided for users who are already friends with a particular ghost NPC or other users, users who have purchased items that are the subject of hashtags using hashtag system 1, users with high popularity (recognition) or influence (i.e., so-called influencers), and users with high status. Popularity and influence may correlate with the popularity of users in the real world. 【0078】 Activity information consists of parameters (information) related to a user's activities within the metaverse space MV. User activities may include not only content distribution and viewing activities by users, live streaming and viewing activities, but also games and parties involving multiple users, conversations between users, movement within the metaverse space MV, and other broad activities such as events and occurrences. Activity information may also include the aforementioned adventure events within the metaverse space MV, as well as hashtag-based experience events (such as trial campaigns). Specifically, for each activity, activity information may include the time spent in the metaverse space MV, login time, and number of logins. 【0079】 The award history is information about a user's award history within the metaverse space MV when the event takes the form of a contest or adventure. For example, the award history may include award history (number of times placed, number of wins, etc.) in various contests and adventures that can be carried out within the metaverse space MV. Similar to the activity information described above, the award history may be collected for all users, including users with normal attributes, but if there is a request to reduce the processing load on the server device 10, it may be collected and managed only for users with special attributes. 【0080】 The number of followers represents the number of followers a given user has. For example, it may be calculated for users who distribute various types of content (e.g., content related to hashtags handled by hashtag system 1), or it may be calculated for all users, including those who do not distribute content. When users with a large number of followers visit hashtag system 1, it has a promotional effect on hashtag system 1 itself. 【0081】 The avatar information storage unit 146 stores avatar rendering information for rendering user avatars and ghost NPCs. For each avatar ID, if it is a human representation, the avatar rendering information associates it with a face part ID, hairstyle part ID, clothing part ID (avatar costume), etc. Appearance-related part information such as face part ID, hairstyle part ID, and clothing part ID is a parameter that characterizes the avatar, and for ghost NPCs, it may be selected by the operator or the advertiser (user). For example, multiple types of appearance-related information such as face part ID, hairstyle part ID, and clothing part ID for ghost NPCs are prepared according to gender, age (generation), advertiser's industry, and ghost NPC role. Furthermore, if the ghost NPC has an appearance different from a human, i.e., if it is a real animal, an imaginary animal, various logos, or a stylized costume, these IDs may be adjusted according to that appearance. 【0082】 The camera unit 151 takes a selfie of the user's avatar and background at the virtual travel destination (place to visit). The background captured during the shoot includes buildings, scenery, and mobility (vehicles) of the travel destination. Furthermore, the camera unit 151 can be equipped with a virtual lens (meta-lens), and when equipped with a virtual lens, the camera unit 151 can capture objects that are not visible to the naked eye in the image. 【0083】 The hashtag assignment unit 152 assigns the corresponding hashtag to the subject captured by the photography unit 151. As mentioned above, when assigning hashtags, considerations are taken into account regarding whether they are automatic tags or user-created tags, whether they are individual hashtags or chained hashtags, and whether they are regular hashtags or rare hashtags. Furthermore, when a collection of items is complete, a complete tag is assigned. In addition, if NFTs, advertisements, or titles are applicable as hashtag targets, hashtags are assigned to each accordingly. 【0084】 In addition to the above, the hashtag assignment unit 152 may also function as the control unit 12 of the server device 10, carrying out missions to facilitate communication between users in the metaverse space using hashtags, and missions to search for advertisements using hashtags. Furthermore, when automatically selecting / searching for ghost NPCs, it may also function to use hashtags to allow users to surf to "unknown" information starting from information they "know". 【0085】 The hashtag display unit 153 associates hashtags with the subject captured by the shooting unit 151 and displays them, for example, on the display unit 25 of the terminal device 20. As mentioned above, hashtags are displayed with an asterisk (*) for automatically generated tags and a sharp (#) for user-created tags. Furthermore, if a title system is provided, hashtags related to titles will be given a title mark. 【0086】 Although not shown in Figure 13, the processing department may also include a research department. The research department investigates whether user satisfaction has been achieved for each avatar item under investigation, based on the values ​​of user parameters relating to past and / or current users who own the avatar item. For example, after using the hashtag system 1, consumer users who purchased a certain avatar item may be investigated to see if they are satisfied with its usage after purchase. The results of the investigation will contribute to the analysis of whether there are elements that increase the item value of the avatar item, or elements that improve the item attributes of the avatar item, as mentioned above. By reflecting the results of this analysis in the content of the hashtags, it is possible to contribute to the development of the hashtag system 1. 【0087】 (Example of hashtag system extension) Hashtag System 1 may be expanded into a comprehensive metaverse system by combining it with other related systems within the metaverse space. Related systems could include, for example, an RPG (Role Playing Game) tour system for surfing the "world" using avatar costumes as a starting point. The RPG tour could, for example, allow users to experience the background story associated with an avatar costume by purchasing and possessing the avatar costume that comes with the tour. For instance, purchasing a Marie Antoinette avatar costume with an RPG tour would allow users to encounter historical episodes about Marie Antoinette during their virtual trip. 【0088】 As described above, by constructing a comprehensive metaverse system including hashtag system 1, it becomes possible to provide various services related to virtual trips utilizing the metaverse space, and users can freely move around the metaverse space and obtain various benefits. 【0089】 Although each embodiment has been described in detail above, the invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope described in the claims. Furthermore, it is possible to combine all or more of the components of the embodiments described above. 【0090】 The invention described in the original claims of the present application is listed below.
