[Sharing 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 related to sharing of target information according to the first embodiment. Here, there exist user terminals 2A, 2B, and 2C used by a plurality of users belonging to the same group as the plurality of user terminals 2, and the target information updated by the symbol selection operation on the user terminal 2A is An example shared between the user terminals 2A, 2B, and 2C will be described.

  In sharing target information, it is assumed that a display control program is executed in each of a plurality of user terminals 2 (user terminals 2A, 2B, and 2C). Each display control unit 241 of the plurality of user terminals 2 is assumed to display target information on the display unit 21. The state of the target information is assumed to be an initial state. Assume that the initial state is a state ST1 shown in FIG.

  First, when a 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). The selection information includes user identification information corresponding to the user terminal 2A and group identification information for identifying a group to which the user of the user terminal 2A belongs.

  The target information receiving unit 121 of the relay device 1 receives selection information as information related to target information that is a target to be displayed on the user terminal 2 from one or more user terminals 2. In the example illustrated in FIG. 5, the target information receiving unit 121 receives 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). And the memory | storage control part 122 memorize | stores the log | history information which shows the update log | history of object information in the memory | storage part 11 (S40). The history information includes group identification information, user identification information, time information indicating the time when the target information is updated, and updated target information.

  Subsequently, the target information transmission unit 123 of the relay device 1 transmits the target information to the user terminal 2 that is the target of transmission of the target information based on the selection information received by the target information reception 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 as transmission targets of the target information.

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

  Subsequently, the specifying unit 124 and the generation 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 that are the transmission targets of the target information, and the generation unit 125 summarizes the time-series change of the target information based on the specified number of user terminals 2. Is generated. 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 between the user terminals 2A, 2B, and 2C. In the example illustrated in FIG. 6, for example, the target information updated by operating the symbol b1 by the user terminal 2A at the time T0 is shared by the user terminals 2A, 2B, and 2C. Further, it shows that the target information updated by operating the symbol b2 by the user terminal 2B at the time T1 is shared by the user terminals 2A, 2B, and 2C.

  In the example illustrated 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, and a2.

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

First, the specifying unit 124 specifies the number of user terminals 2 that are targets of transmission of target information (S710). Specifically, the specifying unit 124 specifies 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 processing according to S730 and S740, thereby generating the summary information based on the number of user terminals 2 specified in S710 and S720, and the second summary method. Select one of the summarization 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 the predetermined value or more.

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

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

  FIG. 9 is a diagram illustrating an example of summary information generated based on the first summary method. The summary information shown in FIG. 9 is summary information generated in response to a change in target information as shown in FIG. The summary information includes time information indicating the time when the target information is updated, information indicating the position of the symbol updated in the target information (operation information), user identification information corresponding to the user terminal 2 that performed the operation, and May be included. The relay device 1 can make the user 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 summarization method, the summary information is displayed based on the last display state at the display position when the display state of the target information at the same display position is continuously updated in the display area where the target information is displayed. It is a method to generate.

  For example, it is assumed that the generation unit 125 selects the second summarization method when the target information changes as illustrated in FIG. In the example shown in FIG. 7, when the display state of the target information at the same display position is continuously updated, the time when the last display state at the display position is changed is T2, T5, T8, T11, T14, T17 and T20. Therefore, the generation unit 125 generates summary information that displays the target information corresponding to the times T2, T5, T8, T11, T14, T17, and T20 illustrated in FIG. 6 in time series based on the second summarization method. 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 illustrating an example of summary information generated based on the second summary method. The summary information shown in FIG. 10 is summary information generated in response to a change in target information as shown in FIG. The relay apparatus 1 can easily grasp the procedure by which the target information is changed until the relay apparatus 1 changes to the latest target information corresponding to the time T23 in FIG. 7 based on the summary information generated by the second method. Can be made.

  In addition, when generating the summary information, the generation unit 125 is based on a plurality of pieces of target information that are traced back from the current time until the reception interval between two pieces of target information reaches a predetermined time or longer (for example, 30 minutes or longer). Thus, summary information may be generated. By doing in this way, the relay apparatus 1 can produce | generate the summary information corresponding to a series of changes of object information.

  Further, when generating the summary information based on the second summarization method, the generation unit 125 goes back from the current time and based on a plurality of pieces of target information until the user terminals 2 that transmitted the information related to the target information are different. Summary information may be generated. By doing in this way, the relay apparatus 1 can produce | generate the summary information which paid its attention to the change of the target information by one user's operation.

  In addition, the target information receiving unit 121 receives initialization instruction information for instructing initialization of target information from the user terminal 2, and the plurality of targets updated after the generation unit 125 last received the initialization instruction information. Summary information may be generated based on the information.

  For example, the display control unit 241 of the user terminal 2 displays target information on the display unit 21 and also displays an initialization button for accepting initialization of the target information on the display unit 21. The target information transmission unit 242 of the user terminal 2 transmits initialization instruction information for instructing initialization of the target information to the relay device 1 in response to 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 deletes 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. Thereby, the generation unit 125 generates summary information based on a plurality of pieces of target information updated after the initialization instruction information is last received. By doing in this way, the relay apparatus 1 can generate the summary information related to the target information updated after being initialized.

  When generating the summary information, the generation unit 125 associates the generated summary information with the group identification information and causes the storage unit 11 to store the summary information (S770).

  In this flowchart, the generation unit 125 is based on the number of user terminals 2 that are specified by the specifying unit 124 and that are transmission targets of the target information, and the number of user terminals 2 that have transmitted the selection information to the relay device 1. However, this is not a limitation.

  For example, the specifying unit 124 may specify the number of user terminals 2 belonging to a group that is a transmission target of the target information. Then, the generation unit 125 may select a 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 to be transmitted and the number of user terminals 2 that have transmitted the selection information to the relay device 1. The operation ratio may be calculated.

  Further, the specifying unit 124 may specify 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. And the production | generation part 125 calculates each operation ratio of the several user terminal 2 based on the sum total of the update frequency, and the update frequency of each target information of the several user terminal 2, and based on the said operation ratio. You may select the summarization method.

  The specifying unit 124 may specify the number of user terminals 2 that are in a predetermined state within a predetermined time from the timing of generating summary information among the user terminals 2 that are transmission targets of the target information. Then, the generation unit 125 may select a summarization method based on the number of the user terminals 2.

  Here, the predetermined state is 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. For example, the target information transmission unit 242 periodically monitors the display state of the user terminal 2 and determines whether or not it is in an active state. When determining that the target information transmission unit 242 is in the active state, the target information transmission unit 242 indicates that it is in the active state, and transmits state information including 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. Based on the state information, the specifying unit 124 specifies the number of user terminals 2 that are in an active state within a predetermined time from the timing of generating summary information. The generation unit 125 transmits the selection information to the relay device 1 within the predetermined time from the timing of generating the summary information and the number of user terminals 2 that are active within the predetermined time from the timing of generating the summary information. Based on the number of terminals 2, the operation ratio of each of the plurality of user terminals 2 is calculated, and the summarization method is selected based on the operation ratio.

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

  The request reception unit 126 of the relay device 1 receives the request information from the user terminal 2 and thereby receives the summary information acquisition request. When 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 reception unit 126 receives a summary information acquisition request, the summary information transmission unit 127 of the relay device 1 converts the summary information generated by the generation unit 125 and stored in the storage unit 11 into the user who transmitted 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 displays the received summary information on the display unit 21 (S140). For example, the display control unit 241 sequentially displays a plurality of pieces of target information constituting 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 a summary information acquisition request. However, the present invention is not limited to this. For example, the summary information transmission unit 127 transmits the summary information to the user terminal 2 that is the transmission target of the target information according to the elapse of a predetermined time from the time when the target information was in the initial state, or every predetermined time. The summary information may be transmitted to the user terminal 2.

[Effect in the first embodiment]
As described above, in the information sharing system S according to the first embodiment, the relay device 1 specifies the number of user terminals 2 that are transmission targets of the target information, 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 that is the transmission target of the summary information. By doing in this way, 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 watch the target information displayed on the display unit 21. Therefore, the relay apparatus 1 can reduce the burden given to the user.

[Share target information by peer-to-peer]
Next, the second embodiment will be described. In the first embodiment, target information is shared among a plurality of user terminals 2 via the relay device 1.

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 transmission unit 242 of the user terminal 2A transmits the updated target information to the user terminals 2B and 2C (S240).

Subsequently, the storage control unit 246 of the user terminal 2A stores the updated target information in the storage unit 23 as history information (S250).
Subsequently, the specifying unit 247 and the generation unit 248 of the user terminal 2A execute a 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. The display control unit 241 of the user terminals 2B and 2C causes the display unit 21 to display the received target information (S270). Thereby, object information is shared between user terminal 2A, 2B, 2C.

Subsequently, the storage control unit 246 of the user terminals 2B and 2C stores the received target information as history information in the storage unit 23 (S280).
Subsequently, the specifying unit 247 and the generation unit 248 of the user terminals 2B and 2C execute a 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]
Subsequently, generation of summary information will be described. FIG. 14 is a flowchart showing a process flow in the summary information generation process according to the second embodiment.

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

Subsequently, the specifying unit 247 specifies 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 according to S830 and S840, thereby generating summary information based on the number of user terminals 2 specified in S810 and S820, One of the summarization methods is selected. Since 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, description thereof is 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, as in the first embodiment, the generation unit 248 determines whether or not the maximum operation ratio among the operation ratios of the plurality of user terminals 2 calculated in S830 is less than a predetermined value (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 it is equal to or larger than the predetermined value.

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

  Note that when generating the summary information, the generation unit 248 includes a plurality of items until the display start time interval of each of the two consecutive pieces of target information reaches a predetermined time or more (for example, 30 minutes or more) retroactively from the current time. The summary information may be generated based on the target information. 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. Based on the display start time stored in the storage unit 23, the generation unit 248 specifies a plurality of pieces of target information until the interval between the display start times of the two pieces of continuous target information reaches a predetermined time or more. And the production | generation part 248 produces | generates summary information based on the specified some target information.

  In addition, when generating the summary information based on the second summarization method, the generation unit 248 traces back from the current time based on a plurality of pieces of target information until the user terminals 2 that transmitted the information related to the target information are different. Summary information may be generated.

  The generation unit 248 may receive an initialization instruction that instructs initialization of 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 displays the target information on the display unit 21 and causes the display unit 21 to display an initialization button for accepting initialization of the target information. The generation unit 248 receives an initialization instruction in response to selection of the initialization button. The target information transmission unit 242 transmits 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 the other user terminal 2.

  The generation unit 248 may generate summary information based on a plurality of pieces of target information updated after receiving an 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. Thereby, the generation unit 248 generates summary information based on a plurality of pieces of target information updated after the initialization instruction information is last received. By doing in this way, the user terminal 2 can produce | generate the summary information which concerns on the target information updated after being initialized.

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

  In this 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 transmitted the target information to other user terminals 2 specified by the specifying unit 247. However, this is not a limitation.

  For example, the specifying unit 247 may specify the number of user terminals 2 that belong to a group that is a transmission target of the target information. In this case, before starting the sharing of the target information, the storage unit 23 associates the group identification information for identifying the group and the user identification information corresponding to the user terminal 2 belonging to the group in accordance with a user operation. Is remembered. Here, the storage unit 23 stores a plurality of group identification information and user identification information corresponding to the user terminals 2 belonging to the group in association with each other. The target information transmission unit 242 accepts selection of a group that shares the target information in accordance with a user operation, and shares the target information by transmitting the target information to the user terminals 2 belonging to the selected group.

  The specifying unit 247 specifies the number of user terminals 2 belonging to the group selected as the transmission target of the target information. The generation unit 248 selects a summarization method based on the identified number of user terminals 2. For example, the generation unit 248 may include a plurality of user terminals 2 based on the number of user terminals 2 belonging to a group that is a target of transmission of target information and the number of user terminals 2 that have transmitted the target information to other user terminals 2. The operation ratio of each is calculated.

  The specifying unit 247 may specify the number of updates of target information by a plurality of user terminals 2 and the number of updates of target information of each of a plurality of user terminals 2. And the production | generation part 248 may calculate each operation ratio of the some user terminal 2 based on these update frequency, and may select a summary system based on the said operation ratio.

  Moreover, the specifying unit 247 may specify the number of user terminals 2 that are in a predetermined state within a predetermined time from the timing of generating summary information among the user terminals 2 that are transmission targets of the target 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 an active state as in the first embodiment. For example, when the target information transmission unit 242 periodically monitors the display state of the user terminal 2 and determines that it is in the active state, the target information transmission unit 242 indicates that it is in the active state, and transmits the state information including the user identification information to other user terminals. 2 to send.

  When the storage control unit 246 receives the state information, the storage control unit 246 stores the state information in association with the time when the state information is received. Based on the state information, the specifying unit 247 specifies the number of user terminals 2 that are in an active state within a predetermined time from the timing of generating summary information. The generation unit 248 transmits the target information to the other user terminals 2 within a predetermined time from the generation time of the summary information and the number of user terminals 2 that are in an active state 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 user terminals 2 that have been selected, and the summarization method is selected based on the operation ratio.

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