  The display processing unit 212 displays a message on the display body 261. The display body 261 is included in the output device 26. The display processing unit 212 causes the display 261 to display the message acquired (received) from the server device 10 using the communication device 24.

  The notification processing unit 213 notifies the supporter 210 of information. Specifically, the notification processing unit 213 notifies the supporter 210 to move to a predetermined location in response to the movement guidance notification from the server device 10. This notification is performed by, for example, displaying on the display body 261, but other methods such as audio output may be used.

The processor 11 of the server device 10 includes a registration unit 111, a first position specifying unit 112, a second position specifying unit 113, a creation unit 114, a display control unit 115, and a notification unit 116.
The registration unit 111 registers at least a message designating a display position in the message DB 131. In the present embodiment, the registration unit 111 acquires a registrant ID, a group ID, a runner ID, a display position, and a message from the message registration device 40 using the communication device 14 and associates them. Are registered in the message DB 131. The message DB 131 is included in the storage 13.

FIG. 4 is a diagram illustrating an example of the configuration of the message DB 131. As shown in FIG. 4, a message ID, a registrant ID, a group ID, a runner ID, and a display position are associated with each of the plurality of messages. Messages with message IDs “M001”, “M003”, “M005”, and “M006” in the message DB 131 are messages addressed to the runner 310 </ b> A, and different display positions are designated. The runner ID of the runner 310A is “603”. The message with the message ID “M004” is a message addressed to the runner 310B. The runner ID of the runner 310B is “112”. These messages are displayed using any of the display devices 20A, 20B, 20C, and 20D belonging to the group with the group ID “G001”. The display device 20E belongs to the group with the group ID “G002”.
It should be noted that the group of supporters 210 possessed by each display device 20 may be managed by the server device 10 using a separate table or the like.

  The first position specifying unit 112 specifies the position of the display body 261. The first position specifying unit 112 uses the communication device 14 to acquire position information from the display device 20, thereby specifying the position indicated by the position information as the position of the display body 261.

  The second position specifying unit 113 specifies the position of the runner 310. The second position specifying unit 113 specifies the position indicated by the position information as the position of the runner 310 by acquiring the position information from the user device 30 using the communication device 14.

  The creation unit 114 creates a message display schedule (hereinafter referred to as “display schedule”) on each display body 261 based on the message registered by the registration unit 111 and the position of each of the plurality of display bodies 261. To do. In the present embodiment, the creation unit 114 generates a message based on information specified from the message DB 131 (for example, the number of messages, a specified display position, and a group ID) and each position of the plurality of display bodies 261. Is created and stored in the storage 13.

FIG. 5 is a diagram illustrating an example of the configuration of the display schedule 132 at a certain time point. As shown in FIG. 5, a display body ID, the number of divisions, and a display time are associated with each of a plurality of message IDs. The message ID corresponds to the message ID of the message DB 131. The display body ID is an identifier of the display body 261 that displays the message with the message ID. If one display device 20 includes one display body 261, the display body ID can be equated with the identifier of the display device 20. The display body ID of the display schedule 132 corresponds to the codes of the display devices 20A to 20E. The number of divisions indicates the number of screen divisions when one or more messages are displayed on the display body 261. When the “number of divisions” is “1”, one message is displayed without dividing the display area of the display body 261. When the “number of divisions” is “N” (N is a natural number of 2 or more), the display area of the display body 261 is divided into N pieces (N pieces in the vertical direction in this embodiment), and 1 is assigned to each display area. Assume that messages are displayed one by one. The display time indicates the length of time for displaying the message indicated by the message ID on the display body 261.
For example, when two or more runners 310 to which a message is addressed pass through the same section at the same time, if the number of divisions is the same as the number of runners 310, the message displayed on the display body 261 may become too small. For this reason, when the number of divisions exceeds the predetermined number of divisions “Nmax”, the creation unit 114 defines the display time and switches the messages in time without dividing the number of divisions. Thus, all messages may be displayed. In FIG. 5, “-” indicates that the content has not yet been determined.

  The display control unit 115 displays a message on the display body 261 of each display device 20 according to the display schedule 132. When the position of the display body 261 and the position of the runner 310 are within a predetermined distance, the display control unit 115 sends a message addressed to the runner 310 in which the display position corresponding to the position of the display body 261 is designated, It is displayed on the display body 261. Here, the display control unit 115 determines the position of the display body 261 and the position of the runner 310 based on the position specified by the first position specifying unit 112 and the position specified by the second position specifying unit 113. It is determined whether or not the distance is within a predetermined distance. Then, for example, the display control unit 115 causes the display body 261 to display a message in which a display position (section) matching the section on the course where the display body 261 exists is specified.

  When the display body 261 does not exist or the number thereof is insufficient at the display position specified in the message registered in the message DB 131, the notification unit 116 determines whether the display body 261 exists at another position. Notification is made to prompt the user to move to the display position.

Next, the operation of this embodiment will be described.
<A: Message registration>
FIG. 6 is a sequence diagram showing processing related to message registration executed in the display system 1.
The message registration device 40 transmits the registrant ID, group ID, runner ID, display position, and message to the server device 10 (step S1). The registrant specifies the runner ID of the runner 310 that he / she wants to support as the runner ID. Further, the registrant uses the display device 20 belonging to which group to specify which place is set as the message display position. The registrant designates the place where the message is to be displayed, for example, from any of the 1st ward, 2nd ward, 3rd ward, and 4th ward, and registers the message. The display position may be specified using a point on the course such as a 5 km point, or may be specified using latitude and longitude.

The registration unit 111 of the server device 10 registers the registrant ID, the group ID, the runner ID, the display position, and the message acquired from the message registration device 40 in the message DB 131 in association with each other (step S2). At this time, the registration unit 111 issues a message ID that does not overlap with that already issued and registers it in the message DB 131.
Message registration may be done either before or during the marathon competition.

<B: Message display>
FIG. 7 is a sequence diagram showing processing related to message display executed in the display system 1. In the display system 1, the processes described below are sequentially executed during the marathon competition.
The information transmission unit 211 of the display device 20 transmits the display body ID, display availability status, and position information of the display device 20 to the server device 10 (step S11). The display permission / prohibition status is data indicating whether or not a message can be displayed on the display device 20. The display availability status indicates that the message cannot be displayed when the supporter 210 is not ready for support (for example, the display device 20 cannot be lifted toward the runner 310). . The display availability status is manually set by the supporter 210, for example. However, the setting is not limited to manual setting, and the display device 20 may make a determination based on information obtained by a sensor or the like. For example, a message cannot be displayed while the display device 20 is moving, and a message can be displayed otherwise.

  When the first position specifying unit 112 of the server device 10 acquires the display body ID, the display availability status, and the position information transmitted by the information transmitting unit 211, the first position specifying unit 112 determines the position of the display body 261 of the display body ID as the position information. Is specified (step S12). On the other hand, the user device 30 transmits the runner ID and position information to the server device 10 (step S13). Next, when the second position specifying unit 113 acquires the runner ID and the position information transmitted by the user device 30, the second position specifying unit 113 specifies the position of the runner 310 of the runner ID as the position indicated by the position information (step S14). ).

  Next, the creation unit 114 creates a display schedule 132 based on the message registered by the registration unit 111 and the positions of the plurality of display bodies 261 (step S15). The creation unit 114 creates a display schedule 132 for the display device 20 whose display availability status indicates that a message can be displayed, excluding the display devices 20 that are not. For example, the creation unit 114 creates the display schedule 132 so that a message to be displayed in a certain section is displayed on the display device 20 existing in the section or nearest to the display position of the message. The creation unit 114 may create the display schedule 132 based on the moving speed and the moving direction of the display device 20 or the runner 310 specified by the temporal change in the position information. For example, the creation unit 114 estimates the time of passing through the position of the display device 20 based on the position and moving speed of the runner 310, and displays a message addressed to the runner 310 at the estimated time. A schedule 132 is created. The creation of the display schedule may be further performed based on the attribute of the message (such as importance) or the attribute of the display body 261 (such as the size of the display area).

  Next, the display control unit 115 determines whether any of the runners 310 and the display body 261 have come within a predetermined distance (step S16). If “NO” is determined in the step S16, the process of the server device 10 is returned to the step S11. If it is determined “YES” in step S16, the display control unit 115 transmits a message associated with the runner ID of the runner 310 in the message DB 131 to the display device 20 having the display body 261 (step S17). . The display processing unit 212 of the display device 20 displays the received message on the display body 261 (step S18).

Here, a display example of the message when the message DB 131 has the configuration shown in FIG. 5 will be described.
FIG. 8 is a display example of a message in the first ward. When the runner 310A approaches the display device 20A within a predetermined distance, the display device 20A is a message addressed to the runner 310A and a message in which the first section is designated as the display position (specifically, “Mr. A, pace "Please pay attention to the distribution and do your best!"

FIG. 9 is a display example of messages in the second ward. In this example, it is assumed that the runners 310A and 310B belonging to the group with the group ID “G001” are approaching the display device 20B at substantially the same timing. Further, it is assumed that there are no other supporters 210 belonging to the group with the group ID “G001” in the second ward.
In this case, the display device 20B displays messages for the two runners 310 at the same time. That is, the display processing unit 212 of the display device 20B divides the display body 261 into display areas T1 and T2. Then, the display processing unit 212 displays a message addressed to the runner 310A in the display area T1 (specifically, a message “Mr. A, do not forget to rehydrate!”) And a message addressed to the runner 310B in the display area T2 ( Specifically, the message “I support you, Mr. B from home” is displayed.

<C: Notification to encourage the supporter 210 to move>
When the display body 261 does not exist at the display position specified in the message, or when the number of display bodies 261 present at the display position is insufficient with respect to the number of messages for which a certain display position is specified, The message for the runner 310 may not be displayed satisfactorily. Therefore, the server device 10 has a function of notifying the supporter 210 to move.

FIG. 10 is a sequence diagram illustrating processing related to a notification that prompts the supporter 210 to move, which is executed in the display system 1.
The notification unit 116 of the server device 10 identifies the display position specified by the message registered in the message DB 131 and the position of each display body 261 (step S21). For example, the notification unit 116 specifies the position of the display body 261 based on the position specified by the first position specifying unit 112. Next, the notification unit 116 determines whether or not the number of display bodies 261 equal to or greater than a predetermined threshold exists at the display position specified in the message (step S22). The threshold value is 1 or 2 or more. If “YES” is determined in the step S22, the process of the server device 10 is returned to the step S21.
In addition, the notification part 116 may perform the process of step S21, S22, when the distance of the present position of the runner 310 and the said display position becomes less than a threshold value.

  If it is determined “NO” in step S22, the notification unit 116 transmits to the display device 20 using the communication device 14 a movement guidance notification that notifies the supporter 210 that the movement is urged (step S23). The notification processing unit 213 of the display device 20 notifies the supporter 210 to move based on the movement guide notification (step S24).

  FIG. 11 is a diagram illustrating an example of notification in step S24 performed by the display device 20. FIG. 11 shows a notification example when the display body 261 does not exist in the third ward. In this case, the message “There is a support message for the third ward. Please move to the third ward.” Is displayed on the display device 20B closest to the third ward. The notification may be displayed by a display body on the display device 20 different from the display body 261, for example, a display body dedicated to the notification.

  When the information transmission unit 211 determines that the supporter 210 has moved to the designated location in response to the notification in step S24, the information transmission unit 211 transmits a movement completion notification to the server device 10 (step S25). The creation unit 114 recreates the display schedule 132 in response to the movement completion notification (step S26). The reason for this re-creation is that the arrangement of the display body 261 has changed. When the supporter 210B moves to the third ward, the creation unit 114 recreates the display schedule 132 so that a message addressed to the runner 310A in which the third ward is designated as the display position is displayed on the display device 20B. Thereby, the message addressed to the runner 310A is displayed on the display device 20B moved to the third ward. Note that the server device 10 determines that the display device 20 has moved by notifying an explicit movement completion notification from the display device 20 but notifying the display body ID and position information from the display device 20, and further The display schedule 132 may be recreated.

  In step S <b> 23, the notification unit 116 may transmit a movement guide notification to the display body 261 existing at the position where the runner 310 has already passed. The display body 261 is a display body 261 that displays a message at least once. Thereby, the display body 261 which has already played the role of displaying the message can be used again for displaying the message.

<D: Joint message display>
For example, at the end of the marathon competition, there is a possibility that the number of display bodies 261 that can be used for displaying a message can be afforded. This is because a large number of supporters 210 may gather near the goal point. Therefore, the display system 1 has a function of causing a plurality of display devices in close proximity to display one message together.

  FIG. 12 is a sequence diagram illustrating processing related to the joint display of messages executed in the display system 1. Here, it is assumed that the display devices 20A, 20C, and 20D are close to each other. In this case, the display devices 20A, 20C, and 20D are paired (step S31). In this case, any one of the display devices 20A, 20C, and 20D (for example, the display device 20A) provides the server device 10 with display body IDs indicating the plurality of display devices 20 that are close to each other. Notification is made (step S32). This notification further includes the positional relationship between the display devices 20A, 20C, and 20D. The creation unit 114 of the server device 10 creates the display schedule 132 in response to this notification (step S33). Specifically, the creation unit 114 associates the same message ID with the display body IDs of the plurality of display devices 20 that are close to each other. Here, as shown in FIG. 13, the message “M006” is associated with the display body IDs “20A”, “20C”, and “20D”.

  Next, in accordance with the display schedule 132, the display control unit 115 transmits a message in which 4 wards are designated as the display position addressed to the runner 310A to each of the display devices 20A, 20C, and 20D (steps S34, S35, and S36). . At this time, the display control unit 115 determines which part of the message is to be displayed on the display body 261 of each display device 20 based on the positional relationship between the display devices 20A, 20C, and 20D.

  Next, the display processing unit 212 of the display device 20 displays the received message on the display body 261 (steps S37, S38, and S39). At this time, in the display devices 20A, 20C, and 20D, the portion of the message that is handled by the device itself is displayed on the display body 261. Here, as shown in FIG. 14, one message “Self-recording update is possible !!” is displayed using the display devices 20A, 20C, and 20D arranged side by side. In other words, different parts of the message are displayed on the display devices 20A, 20C, and 20D.

  In the message display in steps S37, S38, and S39, the character size is increased as compared with the case where the entire message is displayed using only one display body 261. Thereby, the display body 261 can be effectively used so that the message can be easily seen from the runner 310. Moreover, since which part of a message is displayed on each display body 261 is determined according to the positional relationship between the display devices 20A, 20C, and 20D, a large burden is not imposed on the supporter 210.

  Note that. The notification in step S32 may not include the positional relationship between the display devices 20A, 20C, and 20D. In this case, the display control unit 115 may determine which part of the message is to be displayed on the display body 261 of each display device 20 by any method. If the supporters 210A, 210C, and 210D (display devices 20A, 20C, and 20D) adjust each other's positional relationship so that the message can be visually recognized from the runner 310 after the message is displayed on the display body 261 of the display device 20. Because it is good.

  According to the display system 1 of the embodiment described above, the message in which the position to be visually recognized by the runner 310 is specified can be displayed when the runner 310 approaches the display body 261 and can visually recognize the display. it can.
