## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a National Phase Patent Application and claims the priority of International Application Number PCT/JP2013/075047, filed on Sep. 17, 2013, which claims priority to Japanese Application No. JP 2012-206705, filed Sep. 20, 2012. The disclosures of which are hereby incorporated by reference.
TECHNICAL FIELD
This application relates to a server, a method for controlling the server, and a control program for the server.
BACKGROUND
With the widespread use of the Internet throughout the general public, there has been a rapid increase not only in passive users who browse the Web and search for information or purchase commodities online, but also in active users who publish quasi-diaries (hereinafter referred to as a “blog”) on the Web or form user communities that share common interests. The spread of blogs throughout the general public represents an emergence and rapid growth of societies on the networks (hereinafter referred to as a “network community”), which are different from the real world and were unimaginable when people were browsing the Web on terminal devices having the capability to connect to the networks.
Under these circumstances, more and more users are using avatars that represent themselves on networks. An avatar, which means “alter ego”, is specifically a so-called character expressed by image data, video data, audio data, or the like; it is acquiring its significance of existence as a pseudo-acting entity in various activities where a user expresses himself/herself, talks, sympathizes or discusses with other users, or builds friendship with people having a common interest in network communities that exist apart from the real world.
Coordinating an avatar's items including hair styles, clothes, accessories, goods, and backgrounds is now one of important activities for a user to draw attention to his/her own senses and preferences in a network community. Users are thus getting or buying these items or giving them to their friends as gifts, which means coordinating avatar items is now one target of economic activity (Patent Literature 1, for example).

SUMMARY
Technical Problem
A variety of items are made available on provider sites including free or paid items. Generally, paid items are of better design, rarer, and more eye-catching, and thus very useful in coordinating items for an avatar. However, free items are often sufficient for the coordinates, and thus only a limited number of users are willing to buy paid items and further give them to their friends as gifts.
Under these circumstances, one conventional way to encourage a user to buy or give as gifts the items is to provide the user with a predetermined incentive. For example, one incentive may be giving one special item to the user who has bought two items as gifts. However, its effect has some definite limit.
It is an object of this application to provide a server, a method for controlling the server, and a control program for the server that can further encourage users to purchase items or give them as gifts, so as to solve these conventional problems.

According to an aspect of the method, there is provided a method for controlling a server including a first storage module for storing possessed objects of a first user and a second user, and a second storage module for storing an object transfer relationship between the first user and the second user in response to a request for transfer of an object from the first user to the second user. The method including receiving, by the server, the request for transfer from a device of the first user, and granting, by the server, a predetermined benefit to the second user if a condition for granting a benefit in relation to an object transfer relationship of the second user with other users is satisfied when an object is transferred in response to the request for transfer.
According to an aspect of the computer program, there is provided a control program for a server including a first storage module for storing possessed objects of a first user and a second user, and a second storage module for storing an object transfer relationship between the first user and the second user in response to a request for transfer of an object from the first user to the second user. The control program causes the server to execute a process. The process including receiving the request for transfer from a device of the first user, and granting a predetermined benefit to the second user if a condition for granting a benefit in relation to an object transfer relationship of the second user with other users is satisfied when an object is transferred in response to the request for transfer.
Advantageous Effects of Invention
In general, a human being feels like returning the favor when given a present. The feelings get much stronger for a more expensive, rarer, or larger amount of present. Therefore, a server, a method for controlling the server, and a control program for the server according to the embodiment enhance such feelings of a transferee user, when an item is transferred to the transferee in response to a request for transfer, by determining whether a benefit granting condition in relation to item transfer relationships between the transferee and other users is satisfied or not, and by granting a predetermined benefit to the transferee user if the condition is satisfied. It is expected that the transferee user, who is granted a benefit as well as given a present, returns the favor by purchasing an item. Additionally, it is expected that the presenter user aggressively purchases and gives items as gifts in expectation of the returned favor and benefits. In this way, users can be further encouraged to purchase items or give them as gifts.

It should be noted that the technical scope of the present invention is not limited to embodiments of the invention but covers the invention described in the claims and its equivalent.
First Embodiment
The first embodiment is applied to a social networking service (hereinafter referred to as “SNS”). SNS, a community-type Web site to help connect users, is a service that provides ways to promote smooth communications among users or to build new human relations. For example, information about a user (e.g., his/her user name, avatar, recent events, messages, and diaries) is sent to the user and other users who are in a friend relationship with the user, and such other users may give comments or evaluations about the information (e.g., “like”) so that users can communicate with one another.
In such SNS, a portable device sends to a server a request for transfer of an item to another user, in response to an instruction from a user. Upon receipt of the request from the portable device, the server transfers an item to the other user. In addition, if a predetermined condition for granting an item is satisfied with regard to the other user owing to the item transfer, the server grants the predetermined item to the other user.

As described above, this embodiment makes it possible to further encourage users to purchase items or give them as gifts, by determining whether a predetermined condition for granting an item is satisfied with respect to the transferee user when an item is transferred to the transferee in response to a request for transfer, and by granting a predetermined item to the transferee user if the predetermined condition for granting an item is satisfied.
It should be noted that this application is not limited to this embodiment. For example, while this embodiment allows a user to transfer an item to another user, the user may additionally send a message or the like when transferring an item.
Moreover, while this embodiment assumes that the condition for granting an item is that a predetermined number of users have transferred items to the transferee user, other conditions for granting items may be used. For example, the condition for granting items may involve the number and attributes of the transferor users, the number and types of transferred items, a point of time or a period, and combinations thereof.
Furthermore, while this embodiment uses one condition for granting an item, a plurality of conditions may be used. In addition, the user and/or any other user may be notified to what extent each condition for granting an item of the user has been satisfied, and which item would be granted to the user if the condition has been fully satisfied. Moreover, when an item is actually granted to a user, the transferor user who transferred an item to the user may be notified that the item is granted to the user, or the granted user may be recommended to send a message or item to the transferor user.
In this embodiment, the example in which the items are transferred has been described. However, the items may be exchanged.
Second Embodiment
In the first embodiment, the condition for granting an item is associated with a first-order transfer relationship between users (i.e., transfer from one user to another user). However, the condition for granting an item may be associated with a second-order transfer relationship between users (e.g., transfer to one user from another user to whom the one user transferred an item in the past). FIG. 8 illustrates an example schematic configuration of a server 3′ in such communication system 1′. The configurations of the communication system 1′ and portable device 2 are identical to those illustrated in FIGS. 1 and 2, and thus their descriptions are omitted below.
The server 3′ includes a server communication module 31, a server storage module 32, and a server processing module 33′. The server communication module 31 and server storage module 32 in these configurations are identical to those illustrated in FIG. 3, and thus their descriptions are omitted below.
The server processing module 33′ includes an item purchase module 331, an item transfer module 332′, an item granting module 333, and a message posting module 334. The item purchase module 331, item granting module 333, and message posting module 334 in these configurations are identical to those illustrated in FIG. 3, and thus their descriptions are omitted below.
Upon receipt of a request for transfer of an item with the parameters: an item ID, transferee user ID, and the like, from the portable device 2 through the server communication module 31, the server processing module 33′ instructs the item transfer module 332′ to carry out an item transfer process with the parameters: the received item ID and transferee user ID as well as the previously received user ID. The operations of deleting and storing an item ID and storing text data in the item transfer process are identical to those illustrated in FIG. 7B, and thus their descriptions are omitted below.
The item transfer module 332′ references the item transfer table stored in the server storage 32 and records transfer of an item (stores “1”, for example), using the given user ID and transferee user ID as keys. In addition, when a predetermined condition for granting an item is satisfied with respect to the transferee user, the item transfer module 332′ instructs the item granting module 333 to carry out an item granting process with the parameter: the transferee user ID. It is assumed that the condition for granting an item is that items have been transferred to the transferee user from a predetermined number of users to whom the transferee user had transferred items. Specifically, it is assumed that the condition for granting an item is that the item transfer table stored in the server storage module 32 is referenced with the transferee user ID as a key to identify any user to whom the transferee user once transferred an item, and the item transfer table stored in the server storage module 32 is referenced with the identified user ID and the transferee user ID as keys to count item transfer records, and the resulting count is equal to or greater than a predetermined value.
The item transfer module 332′ exits the item transfer process.
The server processing module 33′ creates data for creating a home screen. The server processing module 33′ sends the created display data for the home screen to the portable device 2 through the server communication module 31.
The operational sequence for the communication system 1′ and the operational flows for the item purchase module 331, item transfer module 332′, item granting module 333, and message posting module 334 are identical to those illustrated in FIGS. 6 and 7, and thus their descriptions are omitted below.
As described above, limiting the condition for granting an item causes users to have a greater zest, making it possible to further encourage users to purchase items or give them as gifts.
It should be noted that this application is not limited to this embodiment. For example, while the condition for granting an item is associated with a second-order transfer relationship between users in this embodiment, the transfer relationship between users may be extended to a third or higher order relationship. For example, the condition for granting an item may be associated with transfer from still another user to one user in the cases where the one user transferred an item to another user, who in turn transferred an item to the still another user.
This application may be applied not only to the communication system and/or item transfers according to this embodiment but also to other services and/or objects that have similar arrangements.
A computer program for implementing the respective functions included in the server processing modules 33 or 33′ on a computer may be provided in the form of a record on a semiconductor record medium, a magnetic record medium, an optical record medium, or any other computer-readable record medium, and may be installed into the server storage module 32 from the record medium through the use of a publicly known setup program or the like.
It should be understood that those skilled in the art can make various changes, substitutions, and modifications to the embodiments without departing from the spirit and scope of this application.
