[Share target information]
First, the flow of processing when sharing target information will be described. FIG. 5 is a sequence diagram showing a flow of processing relating to sharing of target information according to the first embodiment. Here, as the plurality of user terminals 2, there are user terminals 2A, 2B, and 2C used by a plurality of users belonging to the same group, and the target information updated by the symbol selection operation on the user terminal 2A is An example shared by the user terminals 2A, 2B, and 2C will be described.

It is assumed that the display control program is executed in each of the plurality of user terminals 2 (user terminals 2A, 2B, and 2C) when the target information is shared. The display control unit 241 of each of the plurality of user terminals 2 is supposed to display the target information on the display unit 21. The state of the target information is assumed to be the initial state. In the initial state, all symbols are in the state ST1 shown in FIG.

First, when the symbol selection operation is performed, the target information transmission unit 242 of the user terminal 2A transmits selection information indicating the selected symbol to the relay device 1 as information related to the target information (S10, S20). It is assumed that the selection information includes user identification information corresponding to the user terminal 2A and group identification information that identifies a group to which the user of the user terminal 2A belongs.

The target information receiving unit 121 of the relay device 1 receives the selection information from one or more user terminals 2 as information related to the target information to be displayed on the user terminal 2. In the example illustrated in FIG. 5, the target information receiving unit 121 receives the selection information from the user terminal 2A.

The storage control unit 122 of the relay device 1 updates the target information based on the selection information (S30). Then, the storage control unit 122 stores history information indicating the update history of the target information in the storage unit 11 (S40). The history information includes the group identification information included in the selection information, the user identification information, the time information indicating the time when the target information is updated, and the updated target information.

Then, the target information transmitting unit 123 of the relay device 1 transmits the target information to the user terminal 2 that is the target of the target information transmission based on the selection information received by the target information receiving unit 121 (S50). In the example illustrated in FIG. 5, the target information transmission unit 123 transmits the target information to the user terminals 2A, 2B, and 2C that are the target of the target information transmission.

The target information receiving unit 243 of each of the user terminals 2A, 2B, and 2C receives the target information transmitted from the relay device 1. The display control unit 241 of each of the user terminals 2A, 2B, and 2C causes the display unit 21 to display the target information (S60).

Subsequently, the specifying unit 124 and the generating unit 125 of the relay device 1 execute a summary information generation process for generating summary information (S70). The specifying unit 124 specifies the number of user terminals 2 to which the target information is transmitted, and the generating unit 125 summarizes the time-series change of the target information based on the specified number of user terminals 2. To generate. Details of the summary information generation process will be described later.

6 and 7 are diagrams illustrating an example in which target information is shared among the user terminals 2A, 2B, and 2C. In the example illustrated in FIG. 6, for example, the target information updated by the operation of the symbol b1 by the user terminal 2A at time T0 is shared by the user terminals 2A, 2B, and 2C. It also indicates that the target information updated by the operation of the symbol b2 by the user terminal 2B at time T1 is shared by the user terminals 2A, 2B, and 2C.

In the example shown in FIG. 7, the target information is updated only by the user terminal 2A. FIG. 7 shows an example in which the symbol states are updated to the state ST4 shown in FIG. 2B in the order of symbols a1, b1, c1, c2, c3, b3, a3, a2.

[Generate summary information]
Next, generation of summary information will be described. FIG. 8 is a flowchart showing the flow of processing in the summary information generation processing according to the first embodiment.

First, the identifying unit 124 identifies the number of user terminals 2 to which the target information is transmitted (S710). Specifically, the identifying unit 124 identifies the number of user terminals 2 to which the target information is transmitted from the relay device 1 within a predetermined time (for example, 30 minutes) from the timing of generating the summary information.
Subsequently, the specifying unit 124 specifies the number of user terminals 2 that have transmitted the selection information to the relay device 1 within a predetermined time from the timing of generating the summary information (S720).

Subsequently, the generation unit 125 executes the processes of S730 and S740 to generate summary information based on the number of user terminals 2 identified in S710 and S720. Select one of the above summary methods.

Specifically, the generation unit 125 calculates the operation ratio of each of the plurality of user terminals 2 based on the number of user terminals 2 specified in S710 and the number of user terminals 2 specified in S720. (S730).

Subsequently, the generation unit 125 determines whether or not the maximum operation ratio among the calculated operation ratios of the plurality of user terminals 2 is less than a predetermined value (S740). The generation unit 125 moves the process to S750 when the maximum operation ratio is less than the predetermined value, and moves the process to S760 when the maximum operation ratio is equal to or higher than the predetermined value.

In S750, the generation unit 125 selects the first summarization method as the summarization method and generates the summarization information based on the first summarization method. The first summarization method is a method of generating summarization information based on the target information received immediately before the user terminal 2 that has transmitted the target information switches.

For example, it is assumed that the generation unit 125 selects the first summarization method when the target information changes as shown in FIG. In the example shown in FIG. 6, the times corresponding to immediately before the user terminal 2 that transmitted the target information is switched are T0, T2, T3, and T6. Therefore, based on the first summarization method, the generation unit 125 generates the summarization information that displays the target information corresponding to the times T0, T2, T3, and T6 shown in FIG. 6 in time series. Here, the generation unit 125 may include the target state indicating the latest state in the summary information. In the example illustrated in FIG. 6, the generation unit 125 includes the target information corresponding to the time T8 in the summary information.

FIG. 9 is a diagram showing an example of summary information generated based on the first summary method. The summary information shown in FIG. 9 is the summary information generated in response to the change of the target information as shown in FIG. The summary information includes time information indicating the time when the target information was updated, information indicating the position of the symbol updated in the target information (operation information), and user identification information corresponding to the user terminal 2 that performed the operation. May be included. The relay device 1 can allow the user to easily understand how the target information has been updated by a plurality of users based on the summary information generated by the first method.

In S760, the generation unit 125 selects the second summary method as the summary method and generates summary information based on the second summary method. In the second summary method, when the display state of the target information at the same display position in the display area where the target information is displayed is continuously updated, the summary information is displayed based on the last display state at the display position. This is the method of generation.

For example, it is assumed that the generation unit 125 selects the second summary method when the target information changes as illustrated in FIG. 7. In the example illustrated in FIG. 7, when the display state of the target information at the same display position is continuously updated, the time when the display state of the target information is changed to the last display state at the display position is T2, T5, T8, T11, T14, It becomes T17 and T20. Therefore, the generation unit 125 generates the summary information that displays the target information corresponding to the times T2, T5, T8, T11, T14, T17, and T20 shown in FIG. Here, the generation unit 125 may include the target state indicating the latest state in the summary information. In the example illustrated in FIG. 7, the generation unit 125 includes target information corresponding to time T23 in the summary information.

FIG. 10 is a diagram showing an example of summary information generated based on the second summary method. The summary information shown in FIG. 10 is the summary information generated corresponding to the change of the target information as shown in FIG. Based on the summary information generated by the second method, the relay device 1 makes it easy for the user to know how the target information is changed until the latest target information corresponding to the time T23 in FIG. 7 is changed. Can be made.

In addition, when generating the summary information, the generation unit 125 is based on a plurality of pieces of target information until the reception interval of two consecutive pieces of target information reaches a predetermined time or more (for example, 30 minutes or more) from the current time. You may make it generate|occur|produce summary information. By doing so, the relay device 1 can generate summary information corresponding to a series of changes in the target information.

Further, when generating the summary information based on the second summary method, the generation unit 125 traces back from the current time and based on the plurality of target information until the user terminal 2 that has transmitted the information related to the target information is different. You may make it produce|generate summary information. By doing so, the relay device 1 can generate the summary information focusing on the change of the target information due to the operation of one user.

Further, the target information receiving unit 121 receives the initialization instruction information for instructing the initialization of the target information from the user terminal 2, and the generating unit 125 updates the plurality of targets after the initialization instruction information is finally received. The summary information may be generated based on the information.

For example, the display control unit 241 of the user terminal 2 causes the display unit 21 to display the target information and also causes the display unit 21 to display an initialization button that accepts initialization of the target information. The target information transmission unit 242 of the user terminal 2 transmits the initialization instruction information for instructing the initialization of the target information to the relay device 1 in response to the selection of the initialization button. Here, it is assumed that the initialization instruction information includes group identification information corresponding to the user terminal 2 that transmits the initialization instruction information.

When the target information receiving unit 121 of the relay device 1 receives the initialization instruction information from the user terminal 2, the storage control unit 122 erases the history information related to the group identification information included in the initialization instruction information. , The state of the target information is changed to the initial state. As a result, the generation unit 125 generates the summary information based on the plurality of pieces of target information updated after the initialization instruction information was last received. By doing so, the relay device 1 can generate the summary information related to the target information updated after being initialized.

After generating the summary information, the generation unit 125 stores the generated summary information in the storage unit 11 in association with the group identification information (S770).

In the flowchart, the generation unit 125 is based on the number of user terminals 2 that are the target of transmission of the target information and the number of user terminals 2 that have transmitted the selection information to the relay device 1 and are specified by the specifying unit 124. The summary method was selected, but it is not limited to this.

For example, the identifying unit 124 may identify the number of user terminals 2 belonging to the group to which the target information is transmitted. Then, the generation unit 125 may select the summarization method based on the number of the user terminals 2. For example, the generation unit 125 determines each of the plurality of user terminals 2 based on the number of user terminals 2 belonging to the group to which the target information is transmitted and the number of user terminals 2 that transmitted the selection information to the relay device 1. The operation ratio of may be calculated.

Further, the identifying unit 124 may identify the total number of updates of the target information by the plurality of user terminals 2 and the number of updates of the target information of each of the plurality of user terminals 2. Then, the generation unit 125 calculates the operation ratio of each of the plurality of user terminals 2 based on the total number of updates and the number of updates of the target information of each of the plurality of user terminals 2, and based on the operation ratio. You may choose the summary method.

Further, the specifying unit 124 may specify the number of user terminals 2 to which the target information is transmitted that are in a predetermined state within a predetermined time from the timing of generating the summary information. Then, the generation unit 125 may select the summarization method based on the number of the user terminals 2.

Here, the predetermined state is, for example, a state (active state) in which the target information is displayed on the display unit 21 of the user terminal 2 and the user can browse and update the target information. For example, the target information transmission unit 242 periodically monitors the display state of the user terminal 2 and determines whether it is in the active state. When determining that the target information transmission unit 242 is in the active state, the target information transmission unit 242 indicates the active state and transmits the state information including the user identification information to the relay device 1.

The storage control unit 122 of the relay device 1 stores the state information and the time when the state information is received in association with each other. The identifying unit 124 identifies the number of user terminals 2 that are in the active state within a predetermined time from the timing of generating the summary information, based on the state information. The generation unit 125 determines the number of user terminals 2 that are in the active state within a predetermined time from the timing of generating the summary information, and the user who has transmitted the selection information to the relay device 1 within the predetermined time from the timing of generating the summary information. The operation ratio of each of the plurality of user terminals 2 is calculated based on the number of terminals 2, and the digest method is selected based on the operation ratio.

[Send summary information]
Next, the transmission of summary information will be described. FIG. 11 is a sequence diagram showing a flow of processing relating to transmission of summary information according to the first embodiment.

First, the summary information requesting unit 244 of the user terminal 2 transmits request information requesting acquisition of summary information to the relay device 1 (S110). For example, the display control unit 241 causes the display unit 21 to display the target information, and also causes the display unit 21 to display the summary acquisition button for requesting the acquisition of the summary information. The summary information requesting unit 244 transmits the request information to the relay device 1 in response to the selection of the summary acquisition button. Here, the request information includes group identification information corresponding to the source user terminal 2.

The request receiving unit 126 of the relay device 1 receives the request information from the user terminal 2 to receive the request for obtaining the summary information. Upon receiving the request information, the request receiving unit 126 acquires the summary information stored in the storage unit 11 in association with the group identification information included in the request information (S120).

When the request accepting unit 126 accepts the request for obtaining the summary information, the summary information transmitting unit 127 of the relay device 1 sends the summary information generated by the generating unit 125 and stored in the storage unit 11 to the user who is the sender of the request information. It transmits to the terminal 2 (S130).

The summary information receiving unit 245 of the user terminal 2 receives the summary information. The display control unit 241 causes the display unit 21 to display the received summary information (S140). The display control unit 241 sequentially displays, for example, a plurality of pieces of target information forming the summary information in order from the oldest time corresponding to the target information.

In the present embodiment, the summary information transmission unit 127 transmits the request information to the user terminal 2 in response to the request reception unit 126 receiving the acquisition request for the summary information, but the present invention is not limited to this. For example, the summary information transmitting unit 127 may transmit the summary information to the user terminal 2 that is the target of the transmission of the target information in response to the lapse of a predetermined time from the time when the target information is in the initial state, or every predetermined time. The summary information may be transmitted to the user terminal 2 concerned.

[Effects of First Embodiment]
As described above, in the information sharing system S according to the first embodiment, the relay device 1 identifies the number of user terminals 2 to which the target information is transmitted, and summarizes the target information based on the number of the user terminals 2. The generated summary information is generated, and the generated summary information is transmitted to the user terminal 2 to which the summary information is transmitted. By doing so, the user of the user terminal 2 can confirm how the target information has changed by confirming the summary information. Thereby, the user of the user terminal 2 does not have to pay attention to the target information displayed on the display unit 21. Therefore, the relay device 1 can reduce the burden on the user.

<Second Embodiment>

An example shared between 2C will be described.

First, when the symbol selection operation is performed, the display control unit 241 of the user terminal 2A updates the target information and causes the display unit 21 to display the updated target information (S210 to S230).
Subsequently, the target information transmitting unit 242 of the user terminal 2A transmits the updated target information to the user terminals 2B and 2C (S240).

Then, the storage control unit 246 of the user terminal 2A stores the updated target information in the storage unit 23 as history information (S250).
Then, the specification unit 247 and the generation unit 248 of the user terminal 2A execute the summary information generation process (S260). Details of the summary information generation processing according to the second embodiment will be described later.

The target information receiving unit 243 of the user terminals 2B and 2C receives the target information from the user terminal 2A.

Subsequently, the identification unit 247 and the generation unit 248 of the user terminals 2B and 2C execute the summary information generation process (S290). The summary information generation process executed in S290 is the same as the summary information generation process executed in S260.

[Generate summary information]
Next, generation of summary information will be described. FIG. 14 is a flowchart showing the flow of processing in the summary information generation processing according to the second embodiment.

First, the identifying unit 247 identifies the number of user terminals 2 sharing the target information (S810). For example, the identifying unit 247 can communicate with the own terminal within a predetermined time from the timing of generating the summary information, and based on the number of the user terminals 2 that can transmit the target information, the identifying unit 247 can share the target information. Identify the number. Here, the specified user terminal 2 includes its own terminal.

Subsequently, the identifying unit 247 identifies the number of user terminals 2 that have transmitted the target information to other user terminals 2 within a predetermined time from the timing of generating the summary information (S820).
Subsequently, the generation unit 248 executes the processes related to S830 and S840 to generate the summary information based on the number of user terminals 2 specified in S810 and S820. Select one of the above summary methods. The first summarization method and the second summarization method are the same as the first summarization method and the second summarization method according to the first embodiment, and thus the description thereof will be omitted.

Specifically, the generation unit 248 calculates the operation ratio of each of the plurality of user terminals 2 based on the number of user terminals 2 specified in S810 and the number of user terminals 2 specified in S820. (S830).

Subsequently, the generation unit 248 determines whether the maximum operation ratio is less than a predetermined value among the operation ratios of the plurality of user terminals 2 calculated in S830, as in the first embodiment (S840). ). The generation unit 248 moves the process to S850 when the maximum operation ratio is less than the predetermined value, and moves the process to S860 when the maximum operation ratio is not less than the predetermined value.

In S850, the generation unit 248 selects the first summarization method as the summarization method and generates the summarization information based on the first summarization method.
In S860, the generation unit 248 selects the second summary method as the summary method and generates summary information based on the second summary method.

In addition, when generating the summary information, the generation unit 248 traces back from the current time and outputs a plurality of pieces of data until the interval between the display start times of the two pieces of continuous target information becomes a predetermined time or more (for example, 30 minutes or more). The summary information may be generated based on the target information of. In this case, when the display control unit 241 displays the target information, the storage control unit 246 stores the display time of the target information in the storage unit 23 as the display start time. The generation unit 248 identifies a plurality of pieces of target information until the interval between the display start times of two consecutive pieces of target information becomes equal to or more than a predetermined time, based on the display start time stored in the storage unit 23. Then, the generation unit 248 generates summary information based on the specified plurality of target information.

Further, when generating the summary information based on the second summarization method, the generation unit 248 traces back from the current time and based on a plurality of target information until the user terminal 2 that transmitted the information related to the target information is different. You may make it produce|generate summary information.

Further, the generation unit 248 may receive an initialization instruction for instructing initialization of the target information via the input unit 22, or may receive an initialization instruction from another user terminal 2. In this case, the display control unit 241 causes the display unit 21 to display the target information, and also causes the display unit 21 to display an initialization button that accepts initialization of the target information. The generation unit 248 receives the initialization instruction in response to the selection of the initialization button. The target information transmitting unit 242 transmits the initialization instruction information to another user terminal 2 in response to the generation unit 248 receiving the initialization instruction. The generation unit 248 receives the initialization instruction by receiving the initialization instruction information from another user terminal 2.

The generation unit 248 may generate the summary information based on the plurality of pieces of target information updated after receiving the initialization instruction. When the generation unit 248 receives the initialization instruction information from the user terminal 2, the storage control unit 246 deletes the history information stored in the storage unit 23 and changes the state of the target information to the initial state. As a result, the generation unit 248 generates the summary information based on the plurality of pieces of target information that have been updated since the initialization instruction information was last received. By doing so, the user terminal 2 can generate summary information related to the target information updated after being initialized.

After generating the summary information, the generation unit 248 stores the generated summary information in the storage unit 23 (S870).

In the present flowchart, the generation unit 248 is based on the number of user terminals 2 that share the target information and the number of user terminals 2 that have transmitted the target information to other user terminals 2 that are identified by the identifying unit 247. The summary method was selected, but it is not limited to this.

For example, the specifying unit 247 may specify the number of user terminals 2 belonging to the group to which the target information is transmitted. In this case, before the sharing of the target information is started, the group identification information for identifying the group and the user identification information corresponding to the user terminal 2 belonging to the group are associated with each other according to the user's operation, and the storage unit 23 is associated. Memorized in. Here, it is assumed that the storage unit 23 stores a plurality of group identification information and the user identification information corresponding to the user terminals 2 belonging to the group in association with each other. The target information transmission unit 242 shares the target information by accepting the selection of the group to share the target information and transmitting the target information to the user terminals 2 belonging to the selected group according to the user's operation.

The identifying unit 247 identifies the number of user terminals 2 belonging to the group selected as the target for transmitting the target information. The generation unit 248 selects the summary method based on the number of the specified user terminals 2. For example, the generation unit 248 determines the plurality of user terminals 2 based on the number of user terminals 2 belonging to the group to which the target information is transmitted and the number of user terminals 2 that transmitted the target information to other user terminals 2. The respective operation ratios of are calculated.

Further, the identifying unit 247 may identify the number of updates of the target information by the plurality of user terminals 2 and the number of updates of the target information of each of the plurality of user terminals 2. Then, the generation unit 248 may calculate the operation ratio of each of the plurality of user terminals 2 based on the number of updates, and select the summarization method based on the operation ratio.

Further, the specifying unit 247 may specify the number of the user terminals 2 to which the target information is transmitted, which are in a predetermined state within a predetermined time from the timing of generating the summary information. Then, the generation unit 248 may select the summarization method based on the number of the user terminals 2.

Here, it is assumed that the predetermined state is the active state as in the first embodiment. For example, the target information transmitting unit 242 periodically monitors the display state of the user terminal 2 and, when determining that the display state is the active state, indicates that the target terminal is in the active state, and displays the state information including the user identification information in another user terminal. Send to 2.

Upon receiving the state information, the storage control unit 246 stores the state information and the time when the state information is received in association with each other. The identifying unit 247 identifies the number of user terminals 2 that are in the active state within a predetermined time from the timing of generating the summary information based on the state information. The generation unit 248 transmits the number of active user terminals 2 within a predetermined time from the timing of generating the summary information, and the target information to other user terminals 2 within the predetermined time from the timing of generating the summary information. The operation ratio of each of the plurality of user terminals 2 is calculated based on the number of the user terminals 2 that have been operated, and the digest method is selected based on the operation ratio.

[Display summary information]
The summary information receiving unit 249 receives a display request for the summary information from the user. When the display request of the summary information is received, the display control unit 241 causes the display unit 21 to display the summary information stored in the storage unit 23. Note that the summary information receiving unit 249 may transmit the summary information display request to another user terminal 2 when receiving the summary information display request from the user. Then, the display control unit 241 of the other user terminal 2 causes the display unit 21 to display the summary information stored in the storage unit 23 in response to the summary information receiving unit 249 receiving the summary information display request. May be. In addition, when the summary information receiving unit 249 receives a summary information display request from the user, the summary information receiving unit 249 may transmit the summary information to the other user terminal 2 and display the summary information on the other user terminal 2. By doing so, the plurality of user terminals 2 can display the summary information at the same timing.
