Description

[Technical field]

[0001] The present invention relates to a technique for managing information relating to the creation history of an avatar prototype consisting of an avatar including an owner's facial image and a plurality of decorative items that decorate the avatar, and information relating to the exchange process of decorative items, etc. [Background technology]

[0002] In recent years, with the improvement of the processing power of electronic computers such as computers, many 2D and 3D computer graphics are used in IT services such as games and SNS (Social Networking Services). In these services, not only icons and avatars that imitate fictional characters are used, but also avatars that realistically represent real people such as users, and avatars that abstractly represent people's characteristics are increasingly used. As a result, for example, in a game, the effect of improving the user's immersion in the game world is generated by having the main character, who is an avatar that represents the user's characteristics, fight against an enemy character, and by using an avatar that abstractly represents the user as an icon representing the user in an SNS, it is expected that the effect of promoting interaction between users in a virtual space in a similar way to the real world is generated.

[0003] Patent documents 1 and 2 each disclose a technology that uses an avatar that resembles the actual appearance of the player or a co-player in a computer game that uses a head-mounted display to present a virtual space. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2019-012509 A [Patent Document 2] JP 2019-139673 A Summary of the Invention [Problem to be solved by the invention]

[0005] As an example of such avatar usage, avatar promides, which display avatars on a so-called promide, are known. In avatar promides, instead of a general photo, an avatar that resembles the user is displayed on a rectangular card-shaped image, and decorative items such as the user's favorite text, illustrations, glasses to be worn by the avatar, jewelry and other accessories, clothing, and even the avatar's movements such as dancing are added. Since avatar promides allow not only the avatar but also the decorative items attached to the avatar to be appropriately customized according to the user's taste, they are expected to be particularly popular among the younger generation. For example, users can use avatar promides as business cards when interacting with each other on SNS, etc., and can also compete with each other on the taste of decorative items and exchange decorative items.

[0006] However, there are concerns about problems with this type of use. For example, just as in-game items have financial value and are the subject of trade, it is expected that the decorative items that make up avatar promo images will have financial value. In this case, there are concerns that decorative items of high financial value will be defrauded from underage users who do not have sufficient judgmental ability, that extremely unfair item exchanges will occur based on superiority and inferiority in human relationships (for example, between a bully and a bullied person), or that minors who want decorative items of high financial value will exchange them in exchange for illegal activities such as prostitution. On the other hand, it is expected that such decorative items will be created by the users themselves, or distributed free of charge as commemorative goods for games or animation works, making it difficult to grasp their exact financial value, and it is extremely difficult to determine what kind of item exchanges should be restricted.

[0007] The present invention has been made in consideration of the above problems, and aims to provide a technique that enables item exchange between users of avatar prototypes to be carried out within an appropriate range. [Means for solving the problem]

[0016] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. In the following embodiments, examples considered to be the most appropriate embodiments of the present invention will be described, and it goes without saying that the contents of the present invention should not be interpreted as being limited to the specific examples shown in the present embodiments. Of course, any configuration that achieves the same action and effect, even if it is a specific configuration other than that shown in the embodiments, is included in the technical scope of the present invention.

[0017] (Embodiment 1) First, an avatar promo management system according to the first embodiment will be described. As shown in Fig. 1, the avatar promo management system according to the first embodiment includes a promo information input unit 1 for inputting promo information, which is information about an avatar promo to be managed, a promo token generation unit 2 for generating a promo token, which is a non-fungible token corresponding to the avatar promo to be managed, an avatar change information generation unit 3 for generating change information of an avatar constituting the avatar promo based on the input promo information, an item exchange information generation unit 4 for generating exchange information of a decorative item constituting the avatar promo based on the input promo information, a transaction generation unit 5 for generating a transaction to be stored in a block in a distributed ledger corresponding to the promo token based on the avatar change information and the item exchange information, an electronic signature generation unit 6 for generating an electronic signature, which is data proving that the creation and output of information included in the transaction are in accordance with the intention of the holder of the promo token, and an output instruction unit 7 for instructing to output the transaction and the electronic signature to a distributed network associated with the promo token.

[0018] The featured image information input unit 1 is for inputting information about the featured avatar to be managed, and corresponds to the information input means in the claims. Avatar featured images are visual information including images of a computer-generated avatar that resembles a target person, and decorative items that are attached to or placed around the avatar.

[0019] The avatar, which is a component of avatar promide, is composed of a human image that imitates a target person, and includes at least the target person's facial image. There is no limitation on the data format of the image, and it may be, for example, simple image data, or computer graphics consisting of skeletal information (bones), surface information (skin), and weight information that defines the relationship between the two. In addition, the avatar may be either a two-dimensional image or a three-dimensional image, and may be not only a still image but also computer graphics that perform a predetermined movement according to movement information. Although it is a human image that imitates the target person, it is not limited to a human body, and it may be an animal or an imaginary creature, and although it is preferable that it has the characteristics of the target person, it is not necessarily limited to this.

[0020] Moreover, the decorative items, which are components of the avatar promide, are information related to the visual aspects and the like that are expressed on the avatar promide. Specific examples of decorative items include visual information as components of the avatar promide (character strings, images, videos, etc. displayed separately from the avatar), visual information as an accessory to the avatar (accessories such as glasses, earrings, and jewelry, and clothing such as clothes, hats, and shoes), audio information associated with these, and even information on the movement of the avatar (for example, information on the positional change of the skeletal information of the avatar formed by computer graphics, which specifies the movement of the avatar, such as the dance style). More comprehensively, the "decorative items" in the present embodiment 1 refer to all parts of the components of the avatar promide that can be specified and exchanged with others, excluding parts that cannot be exchanged with others, such as the avatar itself. The avatar promide is the totality of information that combines the avatar and the decorative items, and specific examples thereof may be electronic data itself that can be expressed as a video, or a physical structure expressed on a tangible object such as paper. Also, in keeping with the image of a so-called "promide," avatar promides are primarily composed of tangible objects or video data in the shape of a rectangular card, but they may be in a shape other than a rectangular card, and may be composed of three-dimensional rather than two-dimensional video data as a whole.

[0021] The photo information input unit 1 is used to input information about an avatar photo composed of such an avatar and decorative items, and specifically has the function of inputting information about the overall configuration of the avatar at the time the photo is created, information about the decorative items to be installed, information about proposed changes to the shape of the avatar, etc. after the photo is created, and information about a proposal to exchange a specified decorative item already installed for another decorative item owned by another person (corresponding to item exchange information in the claims).

[0022] The featured token generating unit 2 is for generating featured tokens (corresponding to the "non-fungible token" in the claims) which are non-fungible tokens in one-to-one correspondence with featured avatars. The "non-fungible token" refers to a so-called NFT (Non-Fungible Token), that is, a token that has unique data and is therefore non-fungible with other tokens, and is issued, for example, based on ERC721, which is the standard for Ethereum (registered trademark). The featured token in the present embodiment 1 is issued based on ERC721 or other predetermined standards, and is configured such that information such as change information for the avatar part of the corresponding featured avatar and exchange information for decorative items is stored on the blockchain.

[0023] "Blockchain" is a technology that uses encryption technology to synchronize data between multiple computers that make up a distributed network. Specifically, each block is made up of a collection of information about Promade Tokens, such as agreed-upon transaction records, and information for connecting to other blocks (information from the previous block), and a blockchain is made up of multiple blocks that are linked together. Even if data is tampered with on some of the multiple computers, the correct data is selected by majority vote among the other computers, making it extremely difficult to destroy or tamper with data.

[0024] The correspondence between the photograph token and the avatar photograph is a one-to-one link between the photograph token identifier and the identification information of the avatar photograph (identification information may be attached to each avatar photograph, or identification information (such as name) relating to the person to whom the avatar photograph is directed may be used). More directly, the photograph token identifier and the identification information of the avatar photograph may be the same, or a correspondence may be established between them composed of different character strings or the like. Alternatively, the link may be made with URL information on the Internet where the data constituting the avatar photograph is saved.

[0025] In addition, in the first embodiment, the blocks constituting the distributed ledger corresponding to the generated featured tokens are assumed to record transaction records related to transfers of ownership of featured tokens, as well as information related to the avatar change history and the exchange history of each decorative item. Information related to the avatar change history and the exchange history of each decorative item is generated by an avatar change information generator 3 and an item exchange information generator 4, which will be described later, and this information is converted into transactions, which are information output to the distributed network, by a transaction generator 5.

[0026] The generation of the bromine token may be performed by the bromine token generating unit 2 itself, or may be performed by an external system that is directly or indirectly connected to the bromine token generating unit 2 by issuing a predetermined command to the external system. The specific format of the bromine token is not limited to one that complies with ERC721, the standard of Ethereum (registered trademark), and may be any format as long as it is non-fungible and the transaction history is stored on the blockchain.

[0027] The avatar modification information generating unit 3 is for generating modification information for the avatar, which is a component of the avatar promide. Specifically, when the owner of the avatar promide creates a proposed modification for a part of the avatar (both eyes, face outline, hairstyle, leg length, etc.), it has a function of generating data on the area to be modified and difference data on the area before and after the modification as modification information. When the avatar is made of simple image data, the difference data can be a collection of information on the pixels to be modified and the amount of change in color information of the pixels, or when the avatar is made of computer graphics, it may be a collection of information on the vertices that are related to the modification from among the vertices that make up the surface shape and the movement direction and amount of the vertices. The avatar modification information generated by the avatar modification information generating unit 3 is output to the transaction generating unit 5.

[0028] The item exchange information generating unit 4 is for generating exchange information regarding decorative items that are components of an avatar original. The item exchange information generating unit 4 has a function of judging whether or not an exchange proposal for a decorative item inputted via the original photo information input unit 1 is appropriate according to a certain criterion, and generating only those judged to be appropriate as exchange information. Specifically, the item exchange information generating unit 4 includes an interest calculation unit 8 that calculates the degree of interest in the decorative items involved in the exchange, i.e., the decorative item before the exchange and the decorative item after the exchange, and an exchange judgment unit 9 that compares the degree of interest in the decorative item before the exchange and the decorative item after the exchange calculated by the interest calculation unit 8, and judges the exchange proposal to be inappropriate if the difference between the degrees of interest is equal to or greater than a predetermined threshold, and does not generate item exchange information, and generates item exchange information only if the difference is less than the threshold.

[0029] The interest level calculation unit 8 is for calculating the interest level of multiple users (all users in the present embodiment 1) of avatar promides having attributes common to the owner of the managed avatar promides in the decorative items to be exchanged in the item exchange information. Specifically, the interest level calculation unit 8 has a function of calculating the interest level of each decorative item among all users having the common attributes, based on the number of times each user has created and / or viewed content including the decorative items in question, and the viewing frequency and viewing duration in Internet services such as SNS and online games used by the users of the avatar promides. Note that the "content" used by the interest level calculation unit 8 is not limited to videos, music, and still images, but may also be text information such as blogs and messages. In the case of videos and still images, the interest level is calculated if visual information corresponding to an icon is included, and in the case of text information such as music, blogs, and messages, the interest level is calculated if language information or text information indicating the icon, such as the name of the icon or an identification code, is included.

[0030] The attribute information includes the user's age, sex, nationality, educational background, and work history, and the interest level calculation unit 8 has a function of measuring the interest level of each decorative item that is the subject of exchange for users who have attribute information in common with the attributes of the owner of the avatar promo that is the subject of management. For example, the interest level calculation unit 8 calculates the interest level of users who have at least the same age group (e.g., 7 to 9 years old, 10 to 12 years old, 13 to 19 years old, 20 years old or older, etc.) and sex as the user.

[0031] As a specific method for measuring the level of interest, for example, it is desirable to calculate the level of interest D using the following formula, where M is the number of times the content is created, N is the number of times the content is viewed, T(k) (where T(0)=0) is the time when the content was viewed the kth time (k: an integer satisfying 1≦k≦N) (defined as the time when viewing began in this embodiment), V(k) is the duration of viewing the content the kth time, and α, β, and γ are real number coefficients. D = αM + β TIFF2025034480000002.tif730

[0032] When calculating the level of interest D using this formula, by appropriately setting the values ​​of the coefficients α, β, and γ, if a user creates content related to the target decorative item by himself, the more times the content is created, the higher the level of interest will be, and if a user views content created by others more times, the shorter the viewing interval, and the longer the viewing duration, the higher the level of interest will be. Since creating content is generally considered to result in a higher level of interest in the target decorative item than viewing content, it is preferable to set α>β. Furthermore, since the viewing interval tends to be longer when measuring the level of interest based on the behavior of viewing content over a long period of time, it is preferable to set the value of the coefficient γ to a number less than 1 for adjustment purposes.

[0033] The interest level calculation unit 8 may calculate the interest level by a method other than the above formula. Even when calculating by a method other than the above formula, it is preferable to adopt a calculation method in which the more the number of times the content is created, the higher the interest level, the more the number of times the content is viewed and the duration of viewing, and the more frequently the content is viewed (=the shorter the content viewing interval), the higher the interest level. Also, instead of calculating the interest level using all of the number of times the content is created, the number of times the content is viewed, the frequency of viewing the content, and the duration of viewing the content, it is also possible to calculate the interest level using some of these pieces of information. It is also preferable to use the above formula or other calculation method, and round the calculated value to a whole number, or further to use a value ranked in descending order of the calculated value, such as 5, 4, 3, 2, and 1, as the interest level. The interest level calculated by the interest level calculation unit 8 is output to the exchange determination unit 9.

[0034] The exchange determination unit 9 compares the interest level of each decorative item to be exchanged, i.e., the exchanged item that was previously attached to the avatar prototype and is scheduled to be deleted as an exchange target in the item exchange information, with the interest level of an exchange item that is scheduled to be newly attached to the avatar prototype in the item exchange information, to determine whether or not to perform an item exchange. Specifically, the exchange determination unit 9 determines that the exchange is not permitted when the difference between the interest level of the exchange item and the interest level of the exchanged item is equal to or greater than a predetermined threshold, and determines that the exchange is permitted when the difference is less than the threshold, generates item exchange information including information for identifying the avatar prototype and the exchanged item to be managed, and outputs the item exchange information to the transaction generation unit 5.

[0035] The transaction generation unit 5 has a function of generating transactions to be stored in blocks in the distributed ledger, and corresponds to an example of an information generation means in the claims. Specifically, the transaction generation unit 5 generates, as the contents of the transaction, information regarding the change of the name of the promoted token holder, as well as information regarding the avatar change information generated by the avatar change information generation unit 3 and the item exchange information permitted by the exchange determination unit 9.

[0036] The electronic signature generating unit 6 has a function of generating an electronic signature, which is data that proves that the creation and output of information included in the transaction is in accordance with the intention of the owner of the promoted token. Specifically, the electronic signature generating unit 6 has a function of generating a hash value of the transaction generated by the transaction generating unit 5, and generating an electronic signature by encrypting the hash value with a private key held by the owner of the promoted token. The "hash value" is a fixed-length value obtained by performing a certain calculation procedure on the original data. Since the calculation procedure is irreversible, it is considered impossible to restore the original data from the hash value. The "private key" is a sequence of numbers used in the encryption process, and is configured to be decryptable by a corresponding "public key." In the first embodiment, the transaction generating unit 5 and the electronic signature generating unit 6 are configured to generate the transaction and electronic signature, which are one aspect of the ownership change information, but this is not necessary, and the transaction generating unit 5 and the electronic signature generating unit 6 may only have a function of instructing an external device to generate the transaction and electronic signature.

[0037] The output instruction unit 7 is for instructing to output the transaction generated by the transaction generation unit 5 and the electronic signature generated by the electronic signature generation unit 6 to the distributed network associated with the provided token. In the first embodiment, the output instruction unit 7 is also provided with an output function itself, and specifically, the output instruction unit 7 is directly or indirectly connected to the distributed network and is configured in a manner capable of outputting predetermined data to the distributed network. The distributed network generates a hash value of the output transaction and compares it with data obtained by decrypting the electronic signature with a public key (= hash value of the transaction). If the two values ​​are different, it is determined that the transaction is not made by the owner of the tangible object in question and rejects the registration, and if the two values ​​match, it is determined that the transaction is made by the owner, and stores the information constituted by the transaction in a block constituting the distributed ledger. The transaction output by the output instruction unit 7 includes information regarding the change of the ownership name, and by outputting the transaction to the distributed network, this information is stored in a block constituting the distributed ledger provided on the distributed network.

[0038] Next, a determination process regarding the decorative item exchange in the avatar featured image management system according to the first embodiment will be described. As shown in FIG. 2, item exchange information is input via featured image information input unit 1 (step S101). Then, the number of times of creation, the number of times of viewing, the viewing interval, and the viewing duration of the content related to the exchanged item listed in the item exchange information are calculated (step S102), and the interest level calculation unit 8 calculates the interest level of the exchanged item based on these values ​​(step S103). Similarly, the number of times of creation, the number of times of viewing, the viewing interval, and the viewing duration of the content related to the exchange item listed in the item exchange information are calculated (step S104), and the interest level calculation unit 8 calculates the interest level of the exchange item based on these values ​​(step S105). Then, the exchange determination unit 9 subtracts the interest level of the exchange item from the interest level of the exchanged item, and determines whether the difference value is equal to or greater than a predetermined threshold value or is less than the threshold value (step S106). If it is equal to or greater than the threshold (step S106, Yes), the exchange determination unit 9 determines that the item exchange is not permitted (step S107), and the process ends. If it is less than the threshold (step S106, No), the exchange determination unit 9 permits the item exchange (step S108), and the transaction generation unit 5 generates a transaction including the item exchange information (step S109), which is output to the distributed network together with the electronic signature.

[0039] Next, advantages of the avatar promide management system according to the first embodiment will be described. First, the avatar promide management system according to the first embodiment employs a configuration in which a promide token, which is a non-fungible token corresponding to an avatar promide, is generated, and information on changes to the avatar and exchange information on decorative items, which are components of the promide token, are recorded in a block in a distributed ledger provided in a distributed network corresponding to the promide. This configuration has the advantage of being able to accurately record the changes that the components of the avatar promide to be managed have undergone (specifically, how the avatar has been changed and how the decorative items have been exchanged). This allows the holder of the avatar promide to easily grasp information such as what decorative items have been used in the past for his or her avatar promide, and allows the holder to take measures such as returning to the original decorative items as necessary. In addition, since the first embodiment uses block chain technology, it is impossible for a third party to tamper with the records, and there is also the advantage that extremely high reliability can be ensured for the recorded contents.

[0040] In addition, the avatar profile management system according to the first embodiment employs a configuration in which the interest level calculation unit 8 calculates the interest levels of the exchanged item and the exchange item included in the item exchange information, and if the difference between the interest levels of the two is equal to or greater than a predetermined threshold value, the exchange between the decorative items is not permitted by the exchange determination unit 9, and the exchange is permitted only if it is less than the threshold value. In a situation in which differences in value between decorative items may occur, problems often arise when an item exchange is attempted between decorative items with significantly different values. For example, problems may be considered in which an adult user uses fraudulent tactics to try to defraud a minor who does not have sufficient judgment ability of a high-value decorative item, or there is a significant difference in the superiority / inferiority between users (for example, a bully and a bullied person) and one user is forced to exchange items that he or she does not want, or further, a user such as a minor who does not have sufficient judgment ability may provide inappropriate money or engage in prostitution as a condition for an item exchange in order to obtain a high-value decorative item. In the avatar prototype management system of this embodiment 1, the interest level corresponding to the value information of a decorative item is calculated, and if the difference in interest level exceeds a certain threshold, item exchange is not permitted across the board, thereby providing the advantage that avatar prototypes can be used under a sound system that does not cause the problems described above.

[0041] Furthermore, in general, decorative items of avatar prototypes are not expected to be traded for a fee, and no public trading price is established. Therefore, in the first embodiment, the degree of interest in the decorative item is adopted as an alternative index of value information, but how to calculate the degree of interest is a problem. In this regard, in the first embodiment, the interest degree calculation unit 8 uses one or more pieces of information among the number of times content is created, the number of times viewed, the viewing interval, and the viewing duration related to the decorative item to be calculated, when calculating the degree of interest, thereby making it possible to calculate an objective degree of interest. Of course, no one will go out of their way to create or view content related to a decorative item that they are not interested in, and those who create or view content usually have a certain level of interest in the decorative item. In the first embodiment, focusing on this point, in addition to the number of times content is created and the number of times viewed, the degree of viewing, i.e., the viewing frequency (viewing interval) and the viewing duration are also used as calculation elements, making it possible to calculate an objective degree of interest.

[0042] (Embodiment 2) Next, a description will be given of an avatar profile management system according to embodiment 2. In embodiment 2, components having the same names and reference numerals as those in embodiment 1 will have the same functions as those in embodiment 1 unless otherwise specified.

[0043] Fig. 3 is a schematic diagram showing the configuration of an avatar prototype management system according to embodiment 2. As shown in Fig. 3, the avatar prototype management system according to embodiment 2 newly includes, in addition to the same components as those of the avatar prototype management system according to embodiment 1, a prototype information input unit 10 for inputting information about a plurality of avatar prototypes, an item exchange information storage unit 12 for storing item exchange information among information inputted in an item exchange information generation unit 11, an interest degree calculation unit 13 for calculating an interest degree in an item according to the number of items specified as exchange items and / or exchanged items in the item exchange information about each stored avatar prototype, and an exchange determination unit 14 for comparing the interest degrees calculated by the interest degree calculation unit 13 and permitting item exchange when the difference value is less than a predetermined threshold value.

[0044] The interest level calculation unit 13 has a function of calculating the degree of interest in the exchange item and the exchanged item, similarly to the interest level calculation unit 8 in the embodiment 1. However, as a specific calculation mechanism, the interest level calculation unit 13 has a function of calculating the degree of interest based on the number of times that the exchange item and / or the exchanged item in the target item exchange information is listed as the exchange item and / or the exchanged item in other item exchange information, rather than the number of times that the related content is viewed as in the embodiment 1.

[0045] In the second embodiment, the photograph information input unit 10 is configured to input information on avatar photographs other than the single avatar photograph to be managed, and by adopting such a configuration, item exchange information on other avatar photographs is also input. The interest level calculation unit 13 searches the stored item exchange information for cases in which the decorative item that is the subject of interest level calculation is listed as an exchange item and / or as an exchanged item, and calculates the number of such cases as the interest level.

[0046] In the process of the interest level calculation unit 13, only cases in which the decorative item to be calculated as the interest level is listed as an exchange item or only cases in which the decorative item is listed as an exchangeable item may be searched for, and the number of such cases may be calculated as the interest level. Alternatively, for example, the number of cases listed as exchangeable items may be multiplied by a coefficient greater than 1, and the sum of the cases listed as exchangeable items and the cases listed as exchangeable items may be derived as the interest level. As in the first embodiment, the calculated value may be rounded off, or the calculated value may be ranked in descending order, such as 5, 4, 3, 2, and 1, depending on the magnitude of the calculated value, and the resulting value may be treated as the interest level.

[0047] The exchange determination unit 14 compares the degree of interest in the exchanged item and the exchange item related to the avatar prototype to be managed, calculated by the interest degree calculation unit 13, and allows the item exchange if the difference between the degree of interest in the exchanged item and the exchange item is less than a predetermined threshold, generates item exchange information including information for identifying the avatar prototype to be managed, the exchanged item, and the exchange item, and outputs it to the transaction generation unit 5. In view of the fact that the method of calculating the degree of interest is different from that of embodiment 1, it is preferable that the threshold value used by the exchange determination unit 14 in the determination process is a value different from that of embodiment 1.

[0048] Next, advantages of the avatar featured image management system according to the second embodiment will be described. In the second embodiment, the interest level is calculated based on the number of times an item is listed as an exchangeable item or an exchange item for other avatar featured images. The fact that an item is listed as an exchange item means that a desire has arisen to include that decorative item in one's own avatar featured image. Therefore, by the interest level calculation unit 13 calculating the interest level based on the number of times an item is listed as an exchange item, it has the advantage of being able to objectively clarify the exchange value of the decorative item.

[0049] In addition, in the second embodiment, the number of times an item is listed as an exchangeable item in other cases is also used as a basis for calculating the interest level. An exchangeable item is a decorative item that is deleted from one's own avatar promo, but on the other hand, it is provided to the other party as a payment for an exchange item that the owner of the avatar promo wishes to acquire, and therefore is a decorative item that has the same value as the exchange item that the owner of the avatar promo wishes to acquire. In other words, the fact that the item is listed as an exchangeable item indicates the fact that the item is judged to have a high exchange value, so that the interest level calculation unit 13 calculates the interest level based on the number of times the item is listed as an exchangeable item, which has the advantage of objectively clarifying the high or low exchange value of the decorative item.

[0050] (Modification) Next, an avatar fabricated management system according to a modification of the first and second embodiments will be described. The avatar fabricated management system according to the modification includes an interest level calculation unit 16 that calculates an interest level according to the number of transactions of a target decorative item as shown in Fig. 4, a warning call unit 17 that warns a user who is about to exchange a decorative item with a high interest level, an exchange determination unit 18 that, based on the interest level, determines whether or not to permit an exchange without conditions similar to those of the first and second embodiments, and in addition, grants conditional exchange permission that allows the exchange itself but generates warning information, and an avatar appearance change unit 19 that changes the appearance of the avatar in the avatar fabricated that exchanges decorative items when the exchange determination unit 18 grants conditional exchange permission.

[0051] Unlike interest level calculation units 8 and 13 in the first and second embodiments, interest level calculation unit 16 is configured to calculate the level of interest in a decorative item according to the number of times the decorative item is traded. Specifically, interest level calculation unit 16 has a function of calculating the level of interest according to the number of times the decorative item is exchanged in a certain period (one week, one month, etc.), and may calculate the level of interest directly based on the number of times the decorative item is exchanged, or may set several predetermined ranges for the number of times the decorative item is exchanged and calculate a numerical value (e.g., an integer value from 1 to 5) assigned to each range as the level of interest.

[0052] Furthermore, interest level calculation unit 16 may calculate the interest level according to the amount of change in the number of exchanges, rather than calculating the interest level from the number of exchanges itself. For example, a certain period (one week, one month, etc.) may be set as a unit interval, and the interest level may be calculated based on the ratio of the number of exchanges of the decorative item in the current unit interval to the number of exchanges of the decorative item in the previous unit interval. In this case, too, the ratio of the number of exchanges itself may be calculated as the interest level, or several predetermined ranges may be set for the ratio of the number of exchanges and a numerical value assigned to each range may be calculated as the interest level.

[0053] The attention calling unit 17 is for calling the attention of the user who is about to exchange the decorative item when the interest level calculated by the interest level calculation unit 16 is greater than a predetermined threshold value. Specifically, when the interest level is greater than the threshold value, that is, when the decorative item has a high exchange value, the attention calling unit 17 has a function of displaying a warning to the user so that the user does not easily exchange and give up the decorative item. Specific examples of the warning display include a warning using text data, a warning made by an avatar in an avatar promo owned by the user, or a warning made by changing the shape (expression, etc.) of the face of the avatar. The warning by the attention calling unit 17 makes it possible to prevent the user from unnecessarily exchanging a high-value decorative item with a high interest level for another item. The attention calling unit 17 may be configured to issue a warning recommending item exchange when the interest level calculated by the interest level calculation unit 16 is less than a predetermined threshold value.

[0054] The exchange determination unit 18 performs a determination process based on the difference between the interest level of the exchanged item and the interest level of the exchange item, similar to the exchange determination units 9 and 14 in the first and second embodiments, but has a function of determining "conditional permission" in addition to unconditional permission or denial of item exchange as the determination content. Specifically, the exchange determination unit 18 has a function of conditionally permitting item exchange when it is appropriate to permit item exchange, but there is some doubt about the exchange between decorative items, such as a certain degree of difference in interest level. The "condition" in this modification means that the appearance of the avatar in the avatar prototype that has obtained a decorative item with a high interest level by the appearance modification unit 17 is changed to a certain degree.

[0055] The exchange determination unit 18 preset the first threshold value K1 and the second threshold value K2 (assuming K1>K2) as the threshold values of the difference value of the degree of interest. When D<K2 for the degree of interest D, it is unconditionally determined that the item exchange is permitted. When K1≦D, it is unconditionally determined that the item exchange is not permitted. When K2≦D<K1, it is determined that the item exchange is conditionally permitted. The values of K1 and K2 can be arbitrarily set, and they may be different values for each decorative item, or different values may be set for each user. For example, when a user who has been determined not to permit item exchange in the past or has been determined not to permit it a certain number of times or more is a party to the item exchange, the threshold value K2 is set to a small value. Even if it is a difference value that is unconditionally determined to permit exchange for others, for a user who has been determined not to permit it in the past, it may be determined to be conditionally permitted.

[0056] After performing the determination process, the exchange determination unit 18 generates item exchange information in the same manner as in Embodiments 1 and 2, and when it is determined that the exchange is conditionally permitted, the determination result is further output to the avatar appearance change unit 19.

[0057] The avatar appearance change unit 19 is for changing the appearance of the avatar in the avatar promise of the user who holds the decorative item with a lower degree of interest in the exchange item and the item to be exchanged when receiving information that the conditional exchange permission has been made by the exchange determination unit 18. The part and degree of changing the appearance can be arbitrarily set. More preferably, the avatar appearance change unit 19 has a function of performing appearance change processing on the part forming the face of the avatar so that the favorability decreases, for example, so that the appearance becomes more villainous. Also, as a function of the avatar appearance change unit 19, for a user who has been determined to be conditionally permitted to exchange a plurality of times, the degree of appearance change of the avatar in the avatar promise may be increased.

[0058] By carrying out such processing in the avatar appearance changing unit 19, a user who wishes to exchange items can check the avatar profile of the exchange partner and understand that the exchange partner has previously exchanged items with a certain degree of difference in interest level (≒ an item exchange suspected to be unfairly advantageous to the exchange partner), and can carefully decide whether or not to exchange items. Even if the user is a minor or the like and finds it difficult to make a rational decision about an item exchange, it is expected that the user will be cautious about the item exchange if the exchange partner's avatar appearance has a low level of favorability, which has the effect of preventing the occurrence of unfair avatar exchanges.

[0059] Although the contents of the present invention have been described above in the first and second embodiments, the technical scope of the present invention should not be interpreted as being limited to the specific configurations described in the embodiments. As long as the functions of the present invention can be realized, various modified examples and application examples of the above-mentioned embodiments are also included in the technical scope of the present invention. For example, the attention calling unit 17, the exchange determination unit 18, and the avatar appearance changing unit 19 in the modified examples may be incorporated into the avatar promo management system according to the first or second embodiment. In addition, the criteria for the determination process, such as the threshold value in the exchange determination unit, may be changed according to the relationship between users who exchange items. For example, when users who exchange items are in a parent-child relationship, it is expected that the parent will exchange items with a certain degree of consideration, so it is also desirable to perform the determination process with a looser criterion than usual (increasing the values ​​of the threshold values ​​(both K1 and K2 in the modified example)). [Industrial Applicability]

[0060] INDUSTRIAL APPLICABILITY The present invention can be used as a technique for managing the creation history of avatar promo images consisting of an avatar including an owner's facial image and a number of decorative items that decorate the avatar, as well as the exchange process of decorative items.
