It may be distributed in this state and read from the recording medium into the server device, or may be superimposed on the carrier via the communication network and supplied to the server device.

As shown in FIG. 6, the user management server 20 includes an acquisition unit 610, a specific unit 620, a search unit 630, a generation unit 640, and a presentation unit 650.
Of these, the acquisition unit 610 and the presentation unit 650 are respectively configured to include a control processing device 510 and a communication control device 560. The specific unit 620, the search unit 630, and the generation unit 640 are each configured to include the control processing device 510.

In this embodiment, it is assumed that the exchange request is acquired from the user terminal 10a. The exchange request includes data necessary for generating application information (FIG. 3 (c)).

The other user B designated by the user A is notified that the application has been made. If User B accepts one of the applications when the application is not invalid, a direct exchange is established.
In this embodiment, indirect exchange with a third party is proposed for the purpose of increasing the possibility of exchange without relaxing the geographical conditions. Specifically, the application information will be expanded.

The identification unit 620 identifies the geographical conditions that the user participating in the indirect exchange must meet.
In this embodiment, the condition that the user A's current position and the user B's current position are within a predetermined distance range is specified. It should be noted that the condition that the spot exists within a predetermined distance range from the current position of the user A or the position of the spot existing around the current position of the user B may be specified.

The search unit 630 searches for a user C who satisfies the geographical conditions specified by the specific unit 620 and can be indirectly exchanged between the three parties together with the user A and the user B.
In this embodiment, the same scenario ID as the "demand scenario ID" included in the application information related to user B is specified as the "supply scenario ID" in the own application information, and the application information related to user A is specified. Search for user C who satisfies the condition that the same scenario ID as the included "supply scenario ID" is specified as the "demand scenario ID" in his / her application information.

In this embodiment, information on the application by the direct exchange partner (user A) and the application by the indirect exchange partner (composite user of user A and real user C, synthetic user of user A and virtual user C) is required. The item is presented to user B.
The system of this embodiment does not implement the function of exchanging atypical messages with the exchange partner. Therefore, in this embodiment, it is not necessary for the exchange partner to actually exist, and it is not necessary to show the user B a specific candidate for the exchange partner. Therefore, the presentation unit 650 presents the synthetic user associated with the supply matching the demand of the user B and the demand matching the supply of the user B to the user B as candidates for the exchange partner.

[2-5. Replacement procedure]
FIG. 7 shows a replacement procedure.
The user management server 20 realizes the exchange by the following procedure.
[Procedure 1] Obtain a replacement request from the user terminal 10a (S710). The exchange request includes data necessary for generating application information (FIG. 3 (c)). Application information is generated based on the acquired exchange request, and is stored in the storage device 31 via the data management server 30.

[Procedure 2] Identify the geographical conditions that the user participating in the indirect exchange must meet (S720). Here, the condition that the current position of the user A and the current position of the user B are within a predetermined distance range is specified.
[Procedure 3] A user C that satisfies the geographical conditions specified by the specific unit 620 and is capable of indirect exchange between the three parties together with the user A and the user B is searched for (S730). Here, the same scenario ID as the "demand scenario ID" included in the application information related to user B is specified as the "supply scenario ID" in the own application information, and is included in the application information related to user A. Search for user C who satisfies the condition that the same scenario ID as the "supply scenario ID" is specified as the "demand scenario ID" in his / her application information.

[Procedure 4] When a real user corresponding to user C is not found in [procedure 3], a virtual user C corresponding to user C is generated. (S740). Here, the virtual user C is generated only when a real user corresponding to the user C is expected to appear in the future.
[Procedure 5] The user terminal 10a is replied that the exchange request has been accepted (S750).
[Procedure 6] Notify the user terminal 10b of information notifying the user B that an application for exchange has been made (S760).

[Procedure 7] Information indicating acceptance of any of the applications is received from the user terminal 10b (S770).
[Procedure 8] The exchange process is executed (S780). Here, the scenario that each user wants to provide is deleted from the possession list of the user, and the scenario that each user wants to acquire is added to the possession list of the user.
[Procedure 9] Notify the user terminal 10a and the user terminal 10b that the exchange process is completed (S790). If it is an indirect exchange involving an existing user C, the user terminal 10c is also notified that the exchange process has been completed.

[2-6. Replacement confirmation screen display example]
FIG. 8 shows a display example of the replacement confirmation screen. The exchange confirmation screen 800 is displayed on the user terminal 10 of the user designated as the exchange partner in the exchange application (here, the user terminal 10b of the user B).
As illustrated in FIG. 8, the exchange confirmation screen 800 includes a confirmation wording 810 and an area 820 indicating the exchange content (parties and targets of the exchange).
In region 820, "you" is the nickname of user B, "other party" is the nickname of the exchange partner (for example, the nickname of user A, the nickname of the synthetic user), and "X" and "Y" are the nicknames of the game scenarios to be exchanged. It is a thumbnail.

[3. Modification example]
[3-1. (Modification example 1) Indirect exchange by four or more parties]
In the above embodiment, indirect exchange by three parties, user A associated with supply Sa and demand Da, user B associated with supply Sb and demand Db, and user C associated with supply Sc and demand Dc, respectively. Is proposed (Fig. 9 (a)).
On the other hand, if the concept of indirect exchange is expanded, it is possible to realize indirect exchange by four or more parties.

[3-2. (Modification 2) One aspect of indirect exchange between four parties]
User A associated with supply Sa and demand Da, user B associated with supply Sb and demand Db, respectively, user D associated with supply Sd and demand Dd, and associated with supply Se and demand De, respectively. Indirect exchange by the four parties may be proposed with the user E (FIG. 9 (b)).

For example, on the assumption that the supply Sb matches the demand Da and the supply Sd matches the demand De, and if the supply Sa matches the demand Dd and the supply Se matches the demand Db, the user C needs to actually exist. No.
Therefore, when the real user corresponding to the user C is not found by the search unit 630, the generation unit 640 generates the virtual user C corresponding to the user C even when the above-mentioned pair of the user D and the user E exists. It may be generated.
In this way, by interposing the virtual user C that temporarily associates the objects to be exchanged, indirect exchange can be realized even when four users do not exist in close positions at the same time. It will be possible.

[3-3. (Modification 3) Matching based on demand list information]
In the above embodiment, the user management server 20 (search unit 630) uses the supply list information (FIG. 3 (b)) registered in advance by each user and the application information (FIG. 3 (FIG. 3)) indicating the application history of each user. c)) and are being searched for user C who can be added to the indirect exchange.
On the other hand, assuming that each user has registered the supply list information (FIG. 3 (b)) and the demand list information (FIG. 10) in advance, the user management server 20 (search unit 630) supplies the supply. It is possible to search for user C by using the list information and the demand list information.

Specifically, the search unit 630 searches for a user C who satisfies the geographical conditions specified by the specific unit 620 and can be indirectly exchanged between the three parties together with the user A and the user B.
In the third modification, the same scenario ID as the “demand scenario ID” related to the exchange request is specified in the own supply list information (FIG. 3 (b)), and the “supply scenario ID” related to the exchange request is specified. It is preferable to search for the user C who satisfies the condition that the same scenario ID as the above is specified in the demand list information (FIG. 10).

In addition, [Procedure 3] of the replacement procedure may be modified as follows.
[Procedure 3] A user C that satisfies the geographical conditions specified by the specific unit 620 and is capable of indirect exchange between the three parties together with the user A and the user B is searched for (S730). In the third modification, the same scenario ID as the “demand scenario ID” related to the exchange request is specified in the own supply list information (FIG. 3 (b)), and the “supply scenario ID” related to the exchange request is specified. Search for user C who satisfies the condition that the same scenario ID as is specified in the demand list information (FIG. 10).
