The reception notification processing unit 213 executes reception notification processing that controls reception notifications regarding the reception of content (not limited to, but an example of a notification regarding the reception of content) based on the reception of destination information in accordance with the reception notification processing program 2812 stored in the memory unit 28.

<Information Processing>
1-6 is a flowchart showing an example of the flow of processes executed by each device in this embodiment. From the left, the flowchart shows an example of a process executed by the control unit 21 of the terminal 20A, a process executed by the control unit 11 of the server 10, a process executed by the control unit 21 of the terminal 20B, and a process executed by the control unit 21 of the terminal 20C.

Each step in each process is indicated by a combination of an uppercase letter and a number, and the term "step" is omitted in this specification. Furthermore, the flowcharts described below are merely examples of the processes in this embodiment, and in the flowcharts described below, some steps may not be executed, and additional steps may be inserted. The same applies to other flowcharts in this specification.

First, the control unit 21 of the terminal 20A displays on the display unit 24 an input area for inputting content to be sent to other users in response to an input operation by the user A (A1). For example, as shown in FIG. 1-7, the control unit 21 of the terminal 20A displays on the display unit 24 a chat room R including users B and C of the terminals 20B and 20C, respectively, and user A of the terminal 20A. Then, the control unit 21 of the terminal 20A displays on the display unit 24 an input area 31 for inputting content to be sent to other users registered in the chat room R. Here, an icon U indicating the user who owns the terminal 20 is displayed on the display unit 24 of the terminal 20, but this icon U is added to help identify the owner of the terminal 20 and does not need to be displayed.

The chat room R may be configured as a space where users associated with each other on the terminal 20 or the server 10 exchange content. For example, the chat room R may be configured as a space where users registered on the terminal 20A (e.g., friends registered as partners with whom to exchange content, users with specific accounts followed by user A, etc.) exchange content. The chat room R may also be configured as a chat room in which users other than the user registered on the terminal 20A can participate, a so-called open chat. The open chat is configured so that all users can freely participate, and is a chat room R in which users who have a common hobby or topic, for example, participate and exchange content. Here, "free participation" may indicate that not only users associated with the terminal 20, etc. can participate, but also users not associated with the terminal 20, etc., for example, users not registered as friends on the terminal 20A, can participate. For this reason, a large number of users, for example, 100 people, may be registered in the open chat. Here, it is assumed that users A to C are registered in the open chat of soccer team K. In this disclosure, users A to C are shown as representative examples of users registered in chat room R, but as long as multiple users are registered, this is not limiting.

Next, the control unit 21 of the terminal 20A accepts the content and destination information regarding the destination of the content (A2). Generally, the content transmitted from the terminal 20A to the chat room R is transmitted to the terminals 20B and 20C of all users B and C registered in the chat room R. At this time, the control unit 21 of the terminal 20A may be provided with a function to notify the specific user to whom the destination is specified of the reception of the content, while the content is transmitted to the terminals 20B and 20C of all users B and C when the user A specifies a destination (for example, by mentioning, etc.). For example, when a destination is specified, the content is displayed on the terminals 20B and 20C of all users B and C, and the notification of reception may or may not be output only on the terminal 20 of the specific user to whom the destination is specified. In this embodiment, in this notification function, a specific user is not specified as the destination, but a destination condition (for example, a condition such as a specific location or range) is specified, and the terminal 20 of the user who satisfies the condition is notified of the reception of the content. The notification function notifies the user of the terminal 20 of the receipt of content, and includes, for example, a ringtone, a vibration function, highlighting of the content, display of a notification message (for example, displaying "You've been mentioned"), etc.

For example, the control unit 21 of the terminal 20A may display a position designation button 32 in the menu area 31a of the chat room R to accept input of destination information. Here, the destination information may include location information related to the location. That is, the control unit 21 of the terminal 20A may accept the designation of location information as destination information. The control unit 21 of the terminal 20A displays a position designation screen 33 as shown in FIG. 1-8A based on the input of the user A to the position designation button 32. The position designation screen 33 may include a designated position search unit 33a, a search result display unit 33b, a location information display unit 33c, and a position determination button 33d. The designated position search unit 33a searches for location information input by the user A, and may be configured to allow, for example, a search keyword to be input. For example, a specific event (for example, a match of soccer team K), the name of an event venue (for example, stadium Ka), etc. may be input into the designated position search unit 33a.

For example, when the search keyword "stadium Ka" is input to the specified location search unit 33a, the control unit 21 of the terminal 20A searches for location information based on the search keyword and displays the search results on the search result display unit 33b. Then, when a specific search result "stadium Ka" corresponding to the search keyword is selected by user A from the search results displayed on the search result display unit 33b, the control unit 21 of the terminal 20A displays the location information of the stadium Ka on the location information display unit 33c. Here, the location information display unit 33c may display a map image of the area around the stadium Ka. That is, the control unit 21 of the terminal 20A displays a map image including the location information of the stadium Ka on the display unit 24.

Here, the location information may include specific location information 34 indicating a specific location (e.g., the location of stadium Ka). The specific location information 34 may be composed of, for example, information on the latitude and longitude of the specific location, and information indicating the location of the specific location (e.g., an address, etc.).

At this time, the control unit 21 of the terminal 20A may set the specific position information 34 based on an input by the user A to the map image. For example, the control unit 21 of the terminal 20A may change the position of the specific position information 34 on the map image based on an input by the user A to the map image. This allows the position of the specific position information 34 to be adjusted to a position desired by the user A. Then, the control unit 21 of the terminal 20A determines the position of the specific position information 34 in response to an input operation by the user A to the position determination button 33d.

The location information may also include range information indicating a specific range. For example, when the position determination button 33d is operated, the control unit 21 of the terminal 20A may display range information 35 indicating the specific range on the map image as shown in FIG. 1-8B. The range information 35 may be configured, for example, in a circular shape and displayed so as to surround the specific range centered on the specific location information 34.

Here, the control unit 21 of the terminal 20A may set the range information 35 based on the input by the user A to the map image. For example, the control unit 21 of the terminal 20A may change the position, diameter, shape, etc. of the range information 35 in response to the input operation by the user A to the map image. Then, when the range information 35 is set, the control unit 21 of the terminal 20A may display the value of the range information 35, for example, displaying "within 3 km".

In this way, specific location information 34 and range information 35 are set by user A as location information indicating the destination of the content. That is, the location information includes specific location information 34 and range information 35. Note that the location information may be set by setting either specific location information 34 or range information 35, for example, only range information 35. The control unit 21 of terminal 20A may specify location information including specific location information 34 and range information 35 as destination information of the content in response to an input operation by user A on the position specification button 33e.

When the destination information of the content is specified, the control unit 21 of the terminal 20A may display a first display 36 based on the destination information in the input area 31 as shown in FIG. 1-9. For example, the control unit 21 of the terminal 20A may display a name (such as a building name) representing the destination of the content as the first display 36 in the input area 31 based on the destination information. That is, the control unit 21 of the terminal 20A does not need to display the first display 36 so as to include all of the specific location information 34 and range information 35 specified in the destination information, and may display, for example, the first display 36 indicating a part of the destination information in the input area 31. Here, it is assumed that the control unit 21 of the terminal 20A displays the name "Stadium Ka" indicating the specific location information 34 as the first display 36 in the input area 31. Note that the first display 36 may include a specific symbol, such as "@", that specifies a specific destination. In this manner, the destination information of the content is input to the terminal 20A.

The control unit 21 of the terminal 20A also accepts input of the first content 37 to be sent to the chat room R in the input area 31. When the first content 37 is input by the user A in the input area 31, the control unit 21 of the terminal 20A associates the first display 36 based on the destination information with the first content 37 and displays them in the input area 31. For example, the control unit 21 of the terminal 20A may display the first display 36 and the first content 37 side-by-side so that they are consecutive. Then, in response to the input operation of the user A on the send button 38, the control unit 21 of the terminal 20A transmits the first content 37 input by the user A in the input area 31 and the destination information to the server 10 via the communication unit 22 (A3).

Then, when the control unit 11 of the server 10 receives the first content 37 and the destination information from the terminal 20A via the communication unit 14, it transmits the first content 37 and the destination information to the terminals 20A to 20C of all users A to C registered in the chat room R (B1). As a result, the communication units 22 of the terminals 20A to 20C receive the first content 37 and the destination information.

When the control unit 21 of terminal 20A receives the first content 37 and the destination information, as shown in FIG. 1-10, it displays the second display 39 based on the destination information and the first content 37 in the chat room R (A4). Here, the second display 39 may or may not have the same content as the first display 36 entered in the input area 31. This allows user A of terminal 20A to understand that the first content 37 with the specified destination has been sent based on the second display 39.

The control unit 21 of the terminal 20A may also display the location information specified by the user A in the chat room R. For example, when the location information is set by the user A in the map image shown in FIG. 1-8B, the control unit 21 of the terminal 20A may transmit the first content 37 including the map image to the server 10 in step A3. As a result, the control unit 21 of the terminal 20A may display the map image 35a including the range information 35 together with the first content 37 in the chat room R, as shown in FIG. 1-11. The control unit 21 of the terminal 20A may also associate control information for transitioning to the map image 35a in response to an input operation by the user A with the map image 35a or the first content 37.

Furthermore, the communication unit 22 of terminal 20B receives from the server 10 the first content 37 input by user A of terminal 20A of the multiple terminals 20A to 20C, and the destination information input by user A of terminal 20A. Similarly, the communication unit 22 of terminal 20C receives from the server 10 the first content 37 input by user A of terminal 20A of the multiple terminals 20A to 20C, and the destination information input by user A of terminal 20A.

When the control unit 21 of terminal 20B receives the first content 37 and the destination information from the server 10, as shown in FIG. 1-12A, it displays the first content 37 and a second display 39 based on the destination information in a chat room R including users B and C of the multiple terminals 20B and 20C, and user A of terminal 20A (C1). Then, the control unit 21 of terminal 20B controls a notification regarding the reception of the first content based on the reception of the destination information (C2).

For example, the control unit 21 of the terminal 20B may determine whether or not a notification function for notifying a specific user of the reception of content is set in the first content based on the destination information. The control unit 21 of the terminal 20B may determine whether or not the notification function is set based on the presence or absence of a specific symbol "@" included in the first display 36. When the control unit 21 of the terminal 20B determines that the notification function is set, the control unit 21 of the terminal 20B may determine whether or not the destination information includes user B. Specifically, the control unit 21 of the terminal 20B determines whether or not the location information of the destination information includes the location of user B, that is, whether or not the location of the terminal 20B is included. For example, the control unit 21 of the terminal 20B may obtain its own specific location information and determine whether or not the specific location information is included in the specific location information 34 and range information 35 of the destination information. At this time, the control unit 21 of the terminal 20B may obtain its own specific location information using a positioning system such as GPS (Global Positioning System).

Here, it is assumed that the control unit 21 of the terminal 20B has determined that the location information includes the user B of the terminal 20B (user B is located inside the range information 35). When the location information includes the user B of the terminal 20B, the control unit 21 of the terminal 20B controls the notification regarding the reception of the first content 37.

For example, the control unit 21 of the terminal 20B may or may not control the speaker 26 to output the received sound 40a. The control unit 21 of the terminal 20B may or may not activate a vibration function 40b to vibrate the terminal 20B. The control unit 21 of the terminal 20B may or may not control the display unit 24 to highlight 40c (e.g., display in bold) the first content 37 or the second display 39. The control unit 21 of the terminal 20B may or may not use a notification function in the chat room R application to display a notification message notifying the reception of the first content, such as a notification message such as "You've been mentioned."

Similarly, when the control unit 21 of terminal 20C receives the first content 37 and the destination information from the server 10, it displays the first content 37 and a second display 39 based on the destination information in the chat room R, as shown in FIG. 1-12B (D1). Then, the control unit 21 of terminal 20C controls a notification regarding the reception of the first content based on the reception of the destination information (D2). For example, the control unit 21 of terminal 20C may determine whether or not the location information of the destination information includes the location of user C, i.e., whether or not the location of terminal 20C is included.

Here, it is assumed that the control unit 21 of the terminal 20C has determined that the location information does not include the user C (user C is located outside the range information 35). If the location information does not include the user C of the terminal 20C, the control unit 21 of the terminal 20C does not need to notify the reception of the first content 37.

At this time, the control units 21 of the terminals 20B and 20C may pre-configure the notification function of chat room R to notify only if the users B and C are the target of the content notification, based on the input operations of the users B and C.

In this way, the first content with destination information set is transmitted from terminal 20A to terminals 20B and 20C, and the reception of the first content is notified on terminal 20B of user B, which is included in the location information of the destination information.

The control unit 21 of the terminals 20B and 20C may display a map image 35a including range information 35 in the chat room R based on the destination information, similar to the terminal 20A shown in FIG. 1-11. The control unit 21 of the terminals 20B and 20C may also associate control information for transitioning to the map image 35a with the map image 35a or the first content 37.

Effects of the First Embodiment
In the first embodiment, the display unit 24 of the terminal 20A displays an input area 31 for inputting content. Then, the communication unit 22 of the terminal 20A transmits the first content 37 inputted into the input area 31 by the user A of the terminal 20A and destination information regarding the destination of the content.

As an example of the effect of this configuration, user A of terminal 20A can easily set the destination of first content 37. For example, when many users are registered in chat room R, it was difficult to select each user to specify as the destination of the content. Therefore, by having the control unit 21 of terminal 20A accept the setting of the destination information of the content, user A can set the destinations of multiple users at once.

In addition, in the first embodiment, the destination information may include location information related to the location.

As an example of the effect of such a configuration, user A of terminal 20A can easily set a specific user B included in the location information as the destination of the first content 37.

In addition, in the first embodiment, the location information includes specific location information 34 in which the location is identified and range information 35 (not limited to this, but an example of range information).

As an example of the effect of such a configuration, user A of terminal 20A can easily set a specific user B included in the specific location information 34 and range information 35 as the destination of the first content 37.

In the first embodiment, the display unit 24 of the terminal 20A displays a map image. The control unit 21 of the terminal 20A then sets the specific position information 34 and the range information 35 based on the input of the user A of the terminal 20A on the map image.

As an example of the effect of this configuration, user A of terminal 20A can easily adjust the values of specific location information 34 and range information 35.

In addition, in the first embodiment, the control unit 21 of the terminal 20A associates the first display 36 based on the destination information with the first content 37 and displays them in the input area 31.

As an example of the effect of this configuration, user A of terminal 20A can easily understand the destination of first content 37.

In the first embodiment, the display unit 24 of the terminal 20A displays a chat room R including users B and C of the multiple terminals 20B and 20C, and user A of the terminal 20A. The control unit 21 of the terminal 20A then displays a second display 39 based on the transmitted destination information and a first content 37 in the chat room R.

As an example of the effect of such a configuration, user A of terminal 20A can easily indicate the destination of first content 37 in chat room R.

In the first embodiment, the communication unit 22 of the terminal 20B receives the first content 37 input by the user A of the terminal 20A among the multiple terminals 20A and 20C, and the destination information regarding the destination of the content input by the user A of the terminal 20A. Then, the control unit 21 of the terminal 20B controls the notification regarding the reception of the content based on the reception of the destination information.

As an example of the effect of this configuration, the control unit 21 of the terminal 20B can easily determine whether or not it is included in the destinations of the first content.

In addition, in the first embodiment, the control unit 21 of the terminal 20B controls notifications regarding the reception of the first content 37 when the location information includes the user B of the terminal 20B.

As an example of the effect of such a configuration, user B of terminal 20B can reliably understand that the first content 37 addressed to him/her and included in the location information has been received.

In addition, in the first embodiment, the control unit 21 of the terminal 20B displays the first content 37 and the second display 39 based on the destination information in a chat room R including users B and C of the multiple terminals 20B and 20C, respectively, and user A of the terminal 20A.

As an example of the effect of this configuration, user B of terminal 20B can easily understand the destination of the first content 37.

<First Modification (1)>
In the first embodiment, the location information is set by searching in the designated location search section 33a as shown in FIG. 1-8A, but the present invention is not limited to this as long as information related to the location can be set.

The first variant (1) is a variant in which the location information is set based on the location of user A of terminal 20A.

First, similarly to the first embodiment, the control unit 21 of the terminal 20A receives the content to be sent to the chat room R and the destination information regarding the destination of the content (A2). At this time, the control unit 21 of the terminal 20A may display a location designation button 41 in the input area 31 for designating the location information of the user A as the destination information, as shown in FIG. 1-13. For example, the control unit 21 of the terminal 20A may automatically display the location designation button 41 in the input area 31 when the specific symbol "@" is entered in the input area 31 to designate a specific destination to notify of the reception of the content (e.g., a mention).

When user A operates the position designation button 41, the control unit 21 of the terminal 20A displays the position designation screen 33 on the display unit 24 as shown in FIG. 1-14A. At this time, the position information of user A may be displayed in the position information display unit 33c of the position designation screen 33. The position information display unit 33c may display, for example, a map image including the position information of user A. That is, the control unit 21 of the terminal 20A displays, on the display unit 24, a map image including the position information of user A. Here, the position information may include specific position information 34 indicating the position of user A (for example, latitude and longitude information, information indicating a location, etc.). For example, the control unit 21 of the terminal 20A may acquire the specific position information 34 of user A using a positioning system such as GPS.

The control unit 21 of the terminal 20A may also change the specific position information 34 based on an input by the user A to the map image. For example, the control unit 21 of the terminal 20A may change the position of the specific position information 34 on the map image based on an input by the user A to the map image. This allows the user A to adjust the position of the specific position information 34. For example, the user A may change the position of the specific position information 34 to the position of stadium Ka.

The control unit 21 of the terminal 20A may determine the position of the specific position information 34 in response to an input operation of the user A on the position determination button 33d. At this time, the position information may include range information indicating a specific range. For example, when the position determination button 33d is operated, the control unit 21 of the terminal 20A may display range information 35 indicating the specific range on a map image as shown in FIG. 1-14B. The range information 35 may be displayed, for example, so as to surround a specific range centered on the specific position information 34. Note that if the specific position information 34 has been changed to the position of stadium Ka, the control unit 21 of the terminal 20A may display the specific range centered on the position of stadium Ka.

In this way, the specific location information 34 and range information 35 are set by user A as location information indicating the destination of the content. The control unit 21 of the terminal 20A may specify the location information including the specific location information 34 and range information 35 as the destination information of the content in response to an input operation of the user A on the location specification button 41.

When destination information for the content is specified, the control unit 21 of the terminal 20A may display a first display 36 based on the destination information in the input area 31, as shown in FIG. 1-9. At this time, if the specific location information 34 is set to the location of user A, the control unit 21 of the terminal 20A may cause the first display 36, such as "People Nearby," to be displayed in the input area 31. The control unit 21 of the terminal 20A may also cause the name corresponding to the location of user A, such as the name of a district or the names of surrounding buildings, to be displayed as the first display 36 in the input area 31.

Then, in response to user A's input operation on the send button 38, the control unit 21 of the terminal 20A transmits the first content 37 and the destination information input by user A in the input area 31 to the server 10 via the communication unit 22 (A3).

<Effects of the first modified example (1)>
In the first variant (1), the destination information includes location information related to the location of user A of terminal 20A.

As an example of the effect of such a configuration, user A of terminal 20A can easily set the destination of the first content 37 based on his or her own location.

<First Modification (2)>
In the first embodiment, the control unit 21 of the terminal 20A sets the destination information based on the input of the user A to the map image, but the present invention is not limited to this as long as the destination information can be set.

The first variant (2) is a variant in which the destination information is directly input by user A into the input area 31.

First, as in the first embodiment, the control unit 21 of the terminal 20A receives the content to be sent to the chat room R and destination information regarding the destination of the content (A2). At this time, the control unit 21 of the terminal 20A may receive input of a specific symbol and location information in the input area 31, as shown in FIG. 1-15.

For example, when "@Tokyo ****" is entered in the input area 31, the control unit 21 of the terminal 20A may set the portion entered following the specific symbol "@", "Tokyo ****", as the specific location information 34 (e.g., an address). That is, the location information may include information "Tokyo ****" that is entered based on the entry of the specific symbol "@" by user A of the terminal 20A. Here, the specific symbol "@" indicates a command to specify (e.g., mention) a specific destination to notify of the reception of content. When the control unit 21 of the terminal 20A sets the specific location information 34, it may set range information 35 (e.g., a range of 3 km) within a predetermined range from the specific location information 34.

The control unit 21 of the terminal 20A may also set in advance a specific symbol, such as "/", that specifies the destination information of the content. For example, when "@/stadium Ka" is input in the input area 31, the control unit 21 of the terminal 20A may set the part "stadium Ka" input following the specific symbol "/" as the location information. That is, the location information may include information "stadium Ka" that is input based on the input of the specific symbol "/" by the user A of the terminal 20A. When the control unit 21 of the terminal 20A sets the location information, the control unit 21 may acquire the specific location information 34 of the stadium Ka based on the information. For example, the control unit 21 of the terminal 20A may acquire the specific location information 34 of the stadium Ka by previously associating the names of a plurality of places with the specific location information 34 (for example, latitude and longitude) and storing them in the storage unit 28, and referring to the storage unit 28 based on the input "stadium Ka". Furthermore, the control unit 21 of the terminal 20A may access the server 10 that manages map information or another web server, and search for the specific location information 34 of the stadium Ka based on the input "stadium Ka." When the control unit 21 of the terminal 20A acquires the specific location information 34 of the stadium Ka, the control unit 21 may set range information 35 (for example, a range of 3 km) within a predetermined range from the specific location information 34.

The control unit 21 of the terminal 20A may then accept input of the first content 37 to be sent to the chat room R in the input area 31. When the first content 37 is input by user A in the input area 31, the control unit 21 of the terminal 20A associates the first display 36 based on the destination information with the first content 37 and displays them in the input area 31. Then, in response to user A's input operation on the send button 38, the control unit 21 of the terminal 20A transmits the first content 37 and the destination information input by user A in the input area 31 to the server 10 via the communication unit 22 (A3).

In this embodiment, the control unit 21 of the terminal 20A sets the destination information of the content based on a specific symbol (such as "@" or "/") input in the input area 31, but the present invention is not limited to this as long as the destination information of the content can be set. For example, the control unit 21 of the terminal 20A may set the location information of the content based on specific location information 34 such as "Tokyo ****" input in the input area 31. The control unit 21 of the terminal 20A may also set the destination information of the content based on range information 35 such as "within 3 km of Stadium Ka" input in the input area 31.

<Effects of the first modified example (2)>
In the first modified example (2), the location information includes information input based on input of a specific symbol by user A of terminal 20A.

One example of the effect of this configuration is that the control unit 21 of the terminal 20A can easily set location information.

Second Embodiment
In the first embodiment, the control unit 21 of the terminal 20A sent the first content to the user A without indicating to the user A the information of the target person who is the destination of the first content (e.g., the information of the user B), but when sending the first content, the control unit 21 may indicate to the user A the information of the target person who is the destination of the first content (e.g., the information of the user B).

In the second embodiment, the control unit 21 of the terminal 20A acquires target user information regarding the target users who are the destinations of the first content from among the multiple users B and C registered in the chat room R, and displays the target user information on the display unit 24.

The same components as those in the first embodiment are designated by the same reference numerals and will not be described again. The contents described in the second embodiment are applicable to all of the other embodiments.

<Information Processing>
FIG. 2A is a flowchart showing an example of the flow of processes executed by each device in this embodiment.

First, as in the first embodiment, the control unit 21 of the terminal 20A receives the content and the destination information of the content as shown in FIG. 1-7 (A2). Here, when the destination information of the first content 37 is input by the user A, the control unit 21 of the terminal 20A may request the server 10 to transmit target person information regarding the target person of the destination of the first content 37 among the users A to C of each of the multiple terminals 20A to 20C registered in the chat room R (A21). For example, as shown in FIG. 1-8B, when the specific position information 34 and the range information 35 are set as the destination information by the user A, the control unit 21 of the terminal 20A requests the server 10 to transmit the target person information. At this time, the control unit 21 of the terminal 20A may transmit the destination information to the server 10 together with the request to transmit the target person information.

When the control unit 11 of the server 10 receives the request to send the target information, it requests the terminals 20B and 20C of the users B and C registered in the chat room R to send the user information corresponding to the destination information (B21). For example, the control unit 11 of the server 10 may request the terminals 20B and 20C to send the location information (e.g., specific location information) of the terminals 20B and 20C as the user information based on the destination information sent from the terminal 20A.

When the control unit 21 of terminal 20B receives a request to send user information from the server 10, it transmits the user information to the server 10 (C21). For example, the control unit 21 of terminal 20B may obtain location information of user B using a positioning system such as GPS, and transmit the location information to the server 10 as user information. Similarly, when the control unit 21 of terminal 20C receives a request to send user information from the server 10, it obtains location information of user C, and transmits the location information to the server 10 as user information (D21).

When the control unit 11 of the server 10 receives user information from the terminals 20B and 20C of users B and C registered in the chat room R, the control unit 11 of the server 10 generates target person information based on the user information (B22). For example, the control unit 11 of the server 10 may calculate the number of targets included in the destination information of the first content 37 among users B and C of terminals 20B and 20C, and generate target number information related to the number of targets. For example, the control unit 11 of the server 10 calculates the number of targets included in the range information 35 transmitted from terminal 20A based on the received position information of terminals 20B and 20C, and generates target number information related to the number of targets. Note that the target number information may be, for example, the calculated number of people. Here, the control unit 11 of the server 10 calculates the target number information included in the range information 35 to be 200 people (calculating the number of users present inside the range information 35 to be 200 people). When the control unit 11 of the server 10 generates the target person information, it transmits the target person information to terminal 20A (B23).

At this time, the control unit 11 of the server 10 may or may not transmit the generated target person information to the terminal 20A as is. For example, when the control unit 11 of the server 10 generates the target number information, it may transmit an approximate value of the target number information to the terminal 20A. Specifically, when the control unit 11 of the server 10 calculates that the number of targets included in the range information 35 is 225 people, it may transmit the target number information as approximately 200 people to the terminal 20A.

When the control unit 21 of the terminal 20A receives the target person information from the server 10, the control unit 21 causes the display unit 24 to display target person information regarding the target persons of the first content 37 among the users B and C of each of the multiple terminals 20B and 20C (A22). For example, the control unit 21 of the terminal 20A may cause the display unit 24 to display target number information regarding the number of target persons of the first content 37 among the users B and C of each of the multiple terminals 20B and 20C. For example, the control unit 21 of the terminal 20A may display target number information 42 regarding the number of target persons on the position specification screen 33 where the range information 35 is set, as shown in FIG. 2-2. Also, the control unit 21 of the terminal 20A may display the target number information 42 in the input area 31 where the first display 36 based on the destination information is displayed, as shown in FIG. 2-3.

At this time, the control unit 21 of the terminal 20A may or may not display the target person information received from the server 10 as is on the display unit 24. For example, when the control unit 21 of the terminal 20A receives the target number information 42 from the server 10, the control unit 21 of the terminal 20A may display an approximate value of the target number information 42 on the display unit 24. Specifically, when the control unit 21 of the terminal 20A receives the target number information 42 of 225 people from the server 10, the control unit 21 of the terminal 20A may display the target number information 42 of approximately 200 people on the display unit 24.

This allows user A to grasp target person information regarding the target person to whom the first content 37 is addressed. At this time, the control unit 21 of terminal 20A may accept a change to the destination information, for example a change to the range information 35. Then, similar to the first embodiment, in response to user A's input operation on the send button 38, the control unit 21 of terminal 20A transmits the first content 37 and the destination information input by user A in the input area 31 to the server 10 via the communication unit 22 (A3).

In this embodiment, terminals 20B and 20C are requested to transmit user information (B21) in response to a request from terminal 20A to transmit target information (A21), but the present invention is not limited to this as long as the location information of terminals 20B and 20C can be obtained. For example, the control unit 11 of the server 10 may request terminals 20B and 20C to transmit user information at a predetermined timing. This allows the control unit 11 of the server 10 to know in advance the locations of users B and C registered in chat room R. Then, when the control unit 11 of the server 10 is requested by terminal 20A to transmit target information (B21), it generates target information based on the previously obtained location information of terminals 20B and 20C (B22).

In this embodiment, the control unit 11 of the server 10 obtains the location information of the terminals 20B and 20C by requesting the terminals 20B and 20C to transmit user information, but the present invention is not limited to this as long as the location information of the terminals 20B and 20C can be obtained. For example, the control units 21 of the terminals 20B and 20C may automatically transmit their own location information to the server 10 (for example, transmit location information at a predetermined interval). This allows the control unit 11 of the server 10 to constantly grasp the locations of the users B and C registered in the chat room R. Then, when the control unit 11 of the server 10 is requested by the terminal 20A to transmit the target person information (B21), it generates the target person information based on the previously obtained location information of the terminals 20B and 20C (B22).

Effects of the Second Embodiment
In the second embodiment, the display unit 24 of the terminal 20A displays target information (not limited to, but an example of information regarding the target) regarding the target of the first content 37 among users A to C of each of the multiple terminals 20A to 20C.

As an example of the effect of this configuration, user A of terminal 20A can appropriately set destination information for first content 37.

In addition, in the second embodiment, the display unit 24 of the terminal 20A displays target number information 42 regarding the number of target people who are destinations of the first content 37 among the users A to C of each of the multiple terminals 20A to 20C.

As an example of the effect of such a configuration, user A of terminal 20A can set destination information of first content 37 more appropriately by understanding target number information 42 .
For example, user A of terminal 20A can change range information 35 to set target number information 42 to a desired value, and transmit first content 37 with target number information 42 as the notification target.

<Second Modification Example (1)>
In the second embodiment, the control unit 21 of the terminal 20A displayed the target number of people information 42 on the display unit 24 regardless of the value of the target number of people information 42, but the display of the target number of people information 42 may be restricted depending on the value of the target number of people information 42.

In the second modified example (1), the control unit 21 of the terminal 20A displays the target number information 42 on the display unit 24 when the target number information 42 is equal to or greater than a predetermined number of people.

First, similarly to the second embodiment, the control unit 11 of the server 10 generates target number information 42 regarding the number of target persons who are the destinations of the first content 37, and transmits the target number information 42 to the terminal 20A (B23). Next, when the control unit 21 of the terminal 20A receives the target number information 42 from the server 10, the control unit 21 may determine whether or not to restrict the display of the target number information 42 based on the value of the target number information 42.

For example, the control unit 21 of the terminal 20A may preset a predetermined number of people that limits the display of the target number information 42. When the target number information 42 is equal to or greater than the predetermined number of people, the control unit 21 of the terminal 20A may display the target number information 42 on the display unit 24 as shown in FIG. 2-2 (A22).

On the other hand, the control unit 21 of the terminal 20A may restrict the display of the target number information 42 when the target number information 42 is less than the predetermined number or equal to or less than the predetermined number. For example, the control unit 21 of the terminal 20A may not display the target number information 42 as shown in FIG. 1-8B. In addition, the control unit 21 of the terminal 20A may restrict the display of the target number information 42 to display whether or not a target person exists in the range information 35. Here, the predetermined number for restricting the display of the target number information 42 may be set based on the range information 35.

Then, as in the second embodiment, the control unit 21 of the terminal 20A transmits the first content 37 and the destination information input by the user A in the input area 31 in response to the user A's input operation on the send button 38 shown in FIG. 1-9 to the server 10 via the communication unit 22 (A3).

<Effects of the second modified example (1)>
In the second modified example (1), the target number information 42 is displayed on the display unit 24 when the number of people is equal to or greater than the set number.

As an example of the effect of such a configuration, the control unit 21 of the terminal 20A can appropriately display the target number information 42.
For example, the control unit 21 of the terminal 20A can prevent the target person who is the destination of the first content 37 from being identified by restricting the display of the target number information 42 when the target number information 42 is small.

<Second Modification Example (2)>
In the second embodiment, the target number information 42 indicates the number of targets, but it is not limited to this as long as it is information related to the number of targets.

In the second variant (2), the target number information 42 indicates whether or not a target person is present within the range of the range information 35.

First, similarly to the second embodiment, the control unit 11 of the server 10 generates target person information for the destination of the first content 37 based on the user information received from the terminals 20B and 20C of the users B and C registered in the chat room R (B22). At this time, the control unit 11 of the server 10 may generate target number information 42 indicating whether or not a target person exists within the range of the range information 35 transmitted from the terminal 20A based on the position information received from the terminals 20B and 20C.

When the control unit 11 of the server 10 generates the number of target persons information 42, it transmits the number of target persons information 42 to the terminal 20A (B23). Then, when the control unit 21 of the terminal 20A receives the number of target persons information 42 from the server 10, it displays the number of target persons information 42 on the display unit 24 (A22). For example, when the control unit 21 of the terminal 20A receives the number of target persons information 42 indicating that a target person exists, the control unit 21 of the terminal 20A may display the number of target persons information 42 indicating that a target person exists within the range information 35 on the display unit 24, as shown in FIG. 2-4. On the other hand, when the control unit 21 of the terminal 20A receives the number of target persons information 42 indicating that a target person does not exist, the control unit 21 of the terminal 20A may display the number of target persons information 42 indicating that a target person does not exist within the range information 35 on the display unit 24.

Then, as in the second embodiment, the control unit 21 of the terminal 20A transmits the first content 37 and the destination information input by the user A in the input area 31 in response to the user A's input operation on the send button 38 shown in FIG. 1-9 to the server 10 via the communication unit 22 (A3).

<Effects of the second modified example (2)>
In the second modified example (2), the number-of-target information 42 indicates whether or not a target person is present within the range information 35 .

As an example of the effect of such a configuration, the control unit 21 of the terminal 20A can reliably prevent the target person who is the destination of the first content 37 from being identified.

<Second Modification Example (3)>
In the second embodiment, the control unit 21 of the terminal 20A does not restrict the transmission of content that specifies a notification destination, but the transmission of the content and destination information may be restricted based on the number of people information regarding the chat room R.

In the second variant (3), the control unit 21 of the terminal 20A restricts the transmission of content and destination information based on number information related to the chat room R, for example, the number of targets or the number of users registered in the chat room R.

First, similarly to the second embodiment, the control unit 11 of the server 10 generates target number information 42 regarding the number of target persons to whom the first content 37 is addressed, and transmits the target number information 42 to the terminal 20A (B23). Next, when the control unit 21 of the terminal 20A receives the target number information 42 from the server 10, the control unit 21 may determine whether or not to restrict transmission of the content and destination information based on the value of the target number information 42.

For example, the control unit 21 of the terminal 20A may preset a predetermined number of people to which the transmission of content is restricted. When the value of the target number information 42 is equal to or greater than the predetermined number of people, the control unit 21 of the terminal 20A displays the target number information 42 on the display unit 24 as shown in FIG. 2-2 (A22). Then, the control unit 21 of the terminal 20A transmits the first content 37 and destination information to the server 10 in response to an input operation by user A on the send button 38 shown in FIG. 1-9 (A3).

On the other hand, the control unit 21 of the terminal 20A restricts the transmission of the content and the destination information when the target number information 42 is less than the predetermined number or equal to or less than the predetermined number. For example, the control unit 21 of the terminal 20A may control the input area 31, etc. so that the content or destination information cannot be input. The control unit 21 of the terminal 20A may also control the send button 38 so that input is not possible.

In this embodiment, the control unit 21 of the terminal 20A restricts the transmission of the content and the destination information based on the number of target persons, but the present invention is not limited to this and may restrict the transmission of the content and the destination information based on the number of people information related to the chat room R. The control unit 21 of the terminal 20A may restrict the transmission of the content and the destination information based on, for example, the number of users B and C registered in the chat room R, i.e., the target population. For example, the control unit 21 of the terminal 20A may obtain the number of users B and C registered in the chat room R from the memory unit 28 or the server 10, and restrict the transmission of the content and the destination information if the number is less than a predetermined number or equal to or less than the predetermined number.

Furthermore, when the control unit 11 of the server 10 receives a request to send target information from the terminal 20A, the control unit 11 may refer to the memory unit 15 to obtain the number of users B and C registered in the chat room R. Then, when the number of users B and C registered in the chat room R is less than a predetermined number or equal to or less than the predetermined number, the control unit 11 of the server 10 may send control information to the terminal 20A that restricts the sending of the content and the destination information. This causes the control unit 21 of the terminal 20A to restrict the sending of the content and the destination information based on the control information.

<Effects of the second modified example (3)>
In the second modified example (3), the control unit 21 of the terminal 20A restricts the transmission of the content and the destination information based on the number-of-members information regarding the chat room R.

As an example of the effect of such a configuration, the control unit 21 of the terminal 20A can reliably prevent the target person who is the destination of the first content 37 from being identified.

Third Embodiment
In the second embodiment, the control unit 21 of the terminal 20A displayed the target information in response to input of destination information before transmitting the first content 37, but the target information may also be displayed after transmitting the first content 37.

In the third embodiment, when the control unit 21 of the terminal 20A transmits the first content 37 and the destination information to the server 10, the control unit 21 associates the transmitted first content 37 with target person information regarding the target person of the destination of the first content 37 and displays them in the chat room R.

The same components as those in the first and second embodiments are designated by the same reference numerals and will not be described again. The contents described in the third embodiment are applicable to any of the other embodiments.

First, as in the first embodiment, the control unit 21 of the terminal 20A transmits the first content 37 and destination information input by the user A in the input area 31 to the server 10 via the communication unit 22 in response to the user A's input operation on the send button 38, as shown in FIG. 1-9 (A3). When the control unit 11 of the server 10 receives the first content 37 and the destination information from the terminal 20A, it transmits the first content 37 and the destination information to the terminals 20A-20C of the users A-C registered in the chat room R (B1). Then, when the control units 21 of the terminals 20A-20C receive the first content 37 and the destination information, they may request the server 10 to transmit target person information regarding the target person of the destination of the first content 37.

For example, as shown in the second embodiment, when the control unit 11 of the server 10 generates the target person information (B22) before receiving the first content 37 and the destination information, the control unit 11 of the server 10 may refer to the storage unit 15 to acquire the target person information. When the target person information has not been generated, the control unit 11 of the server 10 may request the terminals 20B and 20C of the users B and C registered in the chat room R to transmit user information (e.g., location information) corresponding to the destination information. When the control unit 11 of the server 10 receives the user information from the terminals 20B and 20C, it generates target information based on the user information. For example, the control unit 11 of the server 10 may calculate the number of targets included in the range information 35 transmitted from the terminal 20A based on the location information of the terminals 20B and 20C, and generate target number information related to the number of targets as target information.

In this way, when the control unit 11 of the server 10 generates the target information, it transmits the target information to the terminals 20A to 20C that requested the transmission of the target information. As a result, the control unit 21 of the terminal 20A causes the second display 39 based on the destination information, the first content 37, and the target information 43 to be displayed in the chat room R (A4), as shown in FIG. 3-1. At this time, the control unit 21 of the terminal 20A may cause the display unit 24 to display the transmitted first content 37 in association with the target information 43 related to the target of the first content 37. For example, the control unit 21 of the terminal 20A may display the target information 43 lined up below the first content 37. At this time, the target information 43 may include target number information related to the number of targets.

Similarly, the control unit 21 of terminal 20B causes the second display 39 based on the destination information, the first content 37, and the destination information to be displayed in chat room R (C1). The control unit 21 of terminal 20C also causes the second display 39 based on the destination information, the first content 37, and target person information 43 to be displayed in chat room R (D1). At this time, the control units 21 of terminals 20B and 20C may cause the display unit 24 to display the transmitted first content 37 in association with target person information 43 related to the target person of the first content 37, in the same manner as terminal 20A.

<Effects of the Third Embodiment>
In the third embodiment, the control unit 21 of the terminal 20A associates the transmitted first content 37 with target person information 43 on the target person who is the destination of the first content 37 and displays them on the display unit 24.

As an example of the effect of this configuration, users A to C registered in chat room R can easily check target user information 43 of first content 37, such as the number of targets.

<Third Modification (1)>
In the third embodiment, the target person information 43 displays target number information regarding the number of targets, but is not limited to this as long as it is information regarding targets who are destinations of the first content 37 .

In the third variant (1), the target information 43 may include view count information regarding the number of users who viewed the first content 37 among the target recipients of the first content 37.

First, similarly to the third embodiment, when the control unit 21 of the terminal 20A receives the target person information 43 from the server 10, it displays the second display 39 based on the destination information, the first content 37, and the target person information 43 in the chat room R (A4). At this time, the target person information 43 may include view count information 44 regarding the number of users (80 people) who viewed the first content 37 out of the number of targets (200 people) who are the destinations of the first content 37, as shown in FIG. 3-2. In addition, the target person information 43 may include total view count information 45 regarding the number of users (350 people) who viewed the first content 37 out of all users registered in the chat room R.

Similarly, the control unit 21 of terminal 20B causes the second display 39 based on the destination information, the first content 37, and the destination information to be displayed in chat room R (C1). The control unit 21 of terminal 20C also causes the second display 39 based on the destination information, the first content 37, and target person information 43 to be displayed in chat room R (D1). At this time, the control units 21 of terminals 20B and 20C may cause the display unit 24 to display target person information 43 including view count information 44 regarding the number of users (80 people) who viewed the first content 37 out of the number of targets (200 people) who are the destinations of the first content 37.

The target information 43 may be displayed on the terminals 20A-C of all users A-C registered in the chat room R, or may be displayed only on the terminal 20A of user A who transmits the first content 37.

<Effects of the third modified example (1)>
In the third variant example (1), target information 43 regarding the target recipients of the first content 37 includes view count information 44 regarding the number of users who viewed the first content 37 among the target recipients of the first content 37 (not limited to this, an example of information regarding the number of users who viewed the first content 37).

As an example of the effect of this configuration, users A to C registered in chat room R can check the target information 43 of the first content 37 in detail.

Fourth Embodiment
In the first to third embodiments, the destination information is composed of location information that specifies the location of the user who is the destination of the content, as shown in, for example, FIG. 1-8A, but is not limited to this as long as it is information regarding the destination of the content.

In the fourth embodiment, the destination information may include attribute information regarding the attributes of the user who is the destination of the content, for example, attribute information set by the user in chat room R.

The same components as those in the first to third embodiments are designated by the same reference numerals and will not be described again. The contents described in the fourth embodiment are applicable to any of the other embodiments.

<Information Processing>
FIG. 4A is a flowchart showing an example of the flow of processes executed by each device in this embodiment.

First, the control unit 21 of the terminal 20A accepts input of attribute information by the user A (A41). Here, the attribute information is information about the attributes of each of the users A to C, such as gender, age, hobbies, date of registration in the chat room R, purchase history, search history, etc.

For example, as shown in FIG. 4-2A, the control unit 21 of the terminal 20A may display profile information 46 of the user A in response to an input operation by the user A, and may provide a setting button 47 for setting attribute information of the user A in the profile information 46. Here, the attribute information may be set as a tag for classifying the user A. When the setting button 47 is input by the user A, the control unit 21 of the terminal 20A may display a setting screen 48 including an input field 49 and a save button 50 as shown in FIG. 4-2B. Then, the control unit 21 of the terminal 20A accepts the input of attribute information by the user A in the input field 49. Here, it is assumed that the attribute information "#Fan of soccer team K", "#Fan for over 10 years", and "#Annual passport member" are input in the input field 49.

Next, the control unit 21 of the terminal 20A transmits the attribute information entered in the input field 49 to the server 10 in response to an input operation by user A on the save button 50 (A42). As a result, the attribute information of user A is set in the server 10. At this time, the attribute information may be set for chat room R, i.e., set for each chat room R. As a result, attribute information specific to the chat room R is set.

Similarly, the control unit 21 of the terminal 20B accepts input of attribute information by the user B (C41) and transmits the attribute information of the user B entered in the input field 49 to the server 10 (C42). The control unit 21 of the terminal 20C also accepts input of attribute information by the user C (D41) and transmits the attribute information of the user C entered in the input field 49 to the server 10 (D42).

The attribute information is not limited to being set after users A to C are registered in chat room R. That is, the attribute information may be set by users A to C before each of users A to C is registered in chat room R including users B and C of terminals 20B and 20C, and user A of terminal 20A. For example, the attribute information may be set by users A to C in the process of registering users A to C in chat room R (joining chat room R). That is, the attribute information may be set at approximately the same time as users A to C are registered in chat room R. Even in this case, the attribute information can be set in the same manner as above, so a description will be omitted.

When the control unit 11 of the server 10 receives the attribute information of users A to C from terminals 20A to 20C, respectively, the control unit 11 stores the attribute information of users A to C in sequence in the storage unit 15 (B41). At this time, the control unit 11 of the server 10 may store the attribute information of each of users A to C as a tag for classifying users A to C. In this way, the attribute information is set by each of users A to C of the multiple terminals 20A to 20C.

Next, as in the first embodiment, the control unit 21 of the terminal 20A causes the display unit 24 to display an input area 31 for inputting content, as shown in FIG. 4-3A, in response to an input operation by the user A (A1). Then, the control unit 21 of the terminal 20A accepts input of the content and destination information regarding the destination of the content (A2).

At this time, the control unit 21 of the terminal 20A may receive attribute information of the users A to C registered in the chat room R as destination information. That is, the destination information may include the attribute information of the users A to C. For example, the control unit 21 of the terminal 20A may receive input of a specific symbol, for example, "#", which displays a list of attribute information of the users A to C registered in the chat room R, set in advance. When the specific symbol "#" is input in the input area 31, the control unit 21 of the terminal 20A requests the server 10 to transmit the attribute information of the users A to C registered in the chat room R (A43). Then, when the control unit 11 of the server 10 receives a request to transmit the attribute information from the terminal 20A, it refers to the storage unit 15 and transmits the attribute information of the users A to C registered in the chat room R to the terminal 20A (B42). For example, the control unit 11 of the server 10 may transmit tag information stored in the storage unit 15 as attribute information to the terminal 20A.

As a result, the control unit 21 of the terminal 20A causes the display unit 24 to display a list 51 of attribute information of the users A to C registered in the chat room R, as shown in FIG. 4-3B. When, for example, "#annual passport member" is selected by the user A in the list 51 of attribute information, the control unit 21 of the terminal 20A may set the attribute information as the destination information of the content.

At this time, the control unit 21 of the terminal 20A may display on the display unit 24 information on the number of subjects who have registered the specific attribute information selected by the user A, as in the second embodiment. For example, the control unit 21 of the terminal 20A may request the server 10 to transmit information on the number of subjects who have registered the specific attribute information. When the control unit 11 of the server 10 receives a request to transmit information on the number of subjects, it calculates the number of users who have registered the specific attribute information and transmits this number to the terminal 20A. As a result, the control unit 21 of the terminal 20A displays information on the number of subjects who have registered the specific attribute information on the display unit 24.

Next, as in the first embodiment, when user A inputs first content 37 into input area 31, control unit 21 of terminal 20A associates first display 36 based on destination information with first content 37 and displays them in input area 31. Then, in response to user A's input operation on send button 38, control unit 21 of terminal 20A transmits first content 37 input into input area 31 by user A and destination information to server 10 (A3).

When the control unit 11 of the server 10 receives the first content 37 and the destination information from terminal 20A, it transmits the first content 37 and the destination information to terminals 20A-20C of all users A-C registered in chat room R (B1). When the control unit 21 of terminal 20B receives the first content 37 and the destination information from the server 10, it displays a second display 39 based on the destination information and the first content 37 in chat room R (C1), as shown in FIG. 4-4A. Then, the control unit 21 of terminal 20B controls notifications regarding the reception of the first content based on the attribute information specified in the destination information (C2).

Here, it is assumed that user B sets "#annual passport member" as the attribute information, and user C does not set any attribute information. If the destination information includes the attribute information "#annual passport member" set by user B, the control unit 21 of terminal 20B controls to output a notification regarding the reception of the first content 37.

Similarly, when the control unit 21 of terminal 20C receives the first content 37 and the destination information from the server 10, it displays the second display 39 based on the destination information and the first content 37 in the chat room R, as shown in FIG. 4-4B (D1). Then, the control unit 21 of terminal 20C controls a notification regarding the reception of the first content 37 based on the reception of the destination information (D2). If the destination information does not include attribute information set by user C, the control unit 21 of terminal 20C does not output a notification regarding the reception of the first content 37.

In this embodiment, the control unit 21 of the terminals 20A to 20C sets attribute information for each chat room R, for example, when registering the users A to C in the chat room R, but this is not limited as long as the attribute information of the users A to C can be set. For example, the control unit 21 of the terminals 20A to 20C may apply the preset attribute information of the users A to C to each chat room R. In other words, the control unit 21 of the terminals 20A to 20C may set the same attribute information to multiple chat rooms R.

Effects of the Fourth Embodiment
In the fourth embodiment, the destination information includes attribute information related to user attributes.

As an example of the effect of such a configuration, user A of terminal 20A can easily set a specific user included in the attribute information as the destination of the first content 37.

In addition, in the fourth embodiment, the attribute information is set by users B and C of each of the multiple terminals 20B and 20C.

As an example of the effect of such a configuration, since attribute information is set for user A of terminal 20A by users B and C, the destination of first content 37 can be appropriately set based on that attribute information.

In addition, in the fourth embodiment, the attribute information is information that is set before registration in chat room R including users B and C of multiple terminals 20B and 20C, and user A of terminal 20A.

One example of the effect of this configuration is that users A to C of terminals 20A to 20C can reliably set attribute information.

In addition, in the fourth embodiment, the attribute information is information that is set for each chat room R.

As an example of the effect of such a configuration, user A of terminal 20A is able to set attribute information specific to chat room R, and can appropriately set the destination of first content 37 based on that attribute information.

In addition, in the fourth embodiment, the control units 21 of the terminals 20B and 20C control notifications regarding the reception of the first content 37 when the destination information includes attribute information set by the users B and C.

As an example of the effect of such a configuration, users B and C of terminals 20B and 20C can easily understand that they have received the first content 37.

Fifth Embodiment
In the first to fourth embodiments, the destination information is composed of location information or attribute information of users B and C, but is not limited to this as long as it is possible to specify a destination to notify of the reception of content.

In the fifth embodiment, the destination information may include period information regarding the period of time the destination belongs to chat room R.

The same components as those in the first to fourth embodiments are designated by the same reference numerals and will not be described again. The contents described in the fifth embodiment are also applicable to any of the other embodiments.

First, as in the first embodiment, the control unit 21 of the terminal 20A displays an input area 31 for inputting content on the display unit 24 in response to an input operation by the user A, as shown in FIG. 5-1 (A1). Then, the control unit 21 of the terminal 20A accepts input of the content and destination information regarding the destination of the content (A2). At this time, the destination information may include period information 52 regarding the period (the period from registration to the present) during which the users B and C of the multiple terminals 20B and 20C belong to the chat room R including the user A of the terminal 20A.

For example, when a specific symbol "@" is entered in the input area 31 to specify a destination to notify of the reception of content (e.g., a mention), the control unit 21 of the terminal 20A may display a list 51 of attribute information including preset period information 52 on the display unit 24. Here, the period information 52 may be information that directly indicates the period of membership in chat room R, such as "a person who has been a member of chat room R for one year or more." Furthermore, the period information 52 may be information that can be used to infer whether or not a user corresponds to the period information 52 based on the period of membership in chat room R, such as "a person who knows when soccer team K won (a specific event)" (for example, if the time of victory is included in the period of membership in chat room R, it is inferred that the user knows when the victory occurred).

When specific period information 52 is selected by user A in the list of attribute information 51, the control unit 21 of the terminal 20A sets the period information 52 as destination information for the content. At this time, the control unit 21 of the terminal 20A may display the target person number information included in the specific period information 52 selected by user A on the display unit 24, as in the second embodiment. For example, the control unit 21 of the terminal 20A may request the server 10 to transmit the target person number information included in the specific period information 52. When the control unit 11 of the server 10 receives a request to transmit the target person number information, it calculates the number of users included in the specific period information 52 and transmits that number to the terminal 20A. As a result, the control unit 21 of the terminal 20A displays the target person number information included in the specific period information 52 on the display unit 24.

Then, in response to user A's input operation on the send button 38, the control unit 21 of the terminal 20A transmits the first content 37 input by user A in the input area 31 and the destination information including the period information 52 to the server 10 (A3).

When the control unit 11 of the server 10 receives the first content 37 and the destination information including the period information 52 from the terminal 20A, it transmits the first content 37 and the destination information to the terminals 20A-20C of the users A-C registered in the chat room R (B1). As a result, the control unit 21 of the terminal 20A displays the second display 39 based on the destination information and the first content 37 in the chat room R (A4).

The control unit 21 of terminal 20B also displays a second display 39 based on the destination information and the first content 37 in chat room R, as shown in FIG. 5-2A for example (C1). Then, the control unit 21 of terminal 20B controls notifications regarding the reception of the first content 37 based on period information 52 indicating the destination information (C2).

Here, when the control unit 21 of the terminal 20B receives the period information 52 of "a person who has been in chat room R for one year or more", the control unit 21 may obtain the period of user B's membership in chat room R from the storage unit 28 or the server 10 and determine whether user B corresponds to the period information 52 (whether the period of membership is one year or more). When the control unit 21 of the terminal 20B receives the period information 52 of a specific event of "a person who knows when soccer team K won the championship", the control unit 21 of the terminal 20B may infer whether user B corresponds to the period information 52 based on the period of user B's membership in chat room R. Specifically, the control unit 21 of the terminal 20B may determine whether the period of user B's membership in chat room R includes the date of the specific event "when soccer team K won the championship" (whether the registration date of chat room R is before "when soccer team K won the championship"), and when it is determined that the period of membership includes the date of the specific event, it may infer that user B corresponds to the period information 52 of "a person who knows when soccer team K won the championship". Then, when the control unit 21 of the terminal 20B determines that the user B corresponds to the period information 52, the control unit 21 may notify the user of the reception of the first content 37. Note that the date "when soccer team K wins the championship" may be obtained, for example, from the server 10, or may be searched for using an external web server.

Similarly, as shown in FIG. 5-2B, the control unit 21 of terminal 20C displays a second display 39 based on the destination information and the first content 37 in chat room R (D1). Then, the control unit 21 of terminal 20C controls the notification regarding the reception of the first content 37 based on the period information 52 indicating the destination information (D2). At this time, if the control unit 21 of terminal 20C determines that user C does not fall under the period information 52 indicating the destination information, it does not notify the reception of the first content 37.

In this embodiment, the control unit 21 of the terminals 20B and 20C determines whether or not users B and C correspond to the period information 52, but the present invention is not limited to this as long as the determination result can be obtained. For example, when the control unit 21 of the terminals 20B and 20C receives the first content 37 and the destination information from the server 10, the control unit 21 may request the server 10 to determine whether or not users B and C correspond to the period information 52 indicating the destination information. When the control unit 11 of the server 10 receives the determination request from the terminals 20B and 20C, the control unit 11 determines whether or not users B and C correspond to the period information 52 based on the membership period of users B and C in the chat room R stored in the storage unit 15. When the control unit 21 of the terminals 20B and 20C obtains the determination result from the server 10, the control unit 21 may control a notification regarding the reception of the first content 37 based on the determination result.

<Effects of the Fifth Embodiment>
In the fifth embodiment, the destination information includes period information 52 (not limited to, but an example of information relating to a period) regarding the period during which a user belongs to a chat room R including users B and C of terminals 20B and 20C, and user A of terminal 20A.

As an example of the effect of such a configuration, user A of terminal 20A can easily set a user corresponding to period information 52 as the destination to be notified of the reception of first content 37.

<Fifth Modification (1)>
In the fifth embodiment, the destination information includes the period information 52 belonging to the chat room R, but is not limited to this as long as it is possible to specify a destination to notify of the reception of the content.

In the fifth variant (1), the destination information includes information about a specific content specified by user A of terminal 20A in chat room R, such as a URL (Uniform Resource Locator), a photo, or a message.

First, as in the fifth embodiment, the control unit 21 of the terminal 20A causes the display unit 24 to display an input area 31 for inputting content in response to an input operation by the user A, as shown in FIG. 5-3A (A1). Then, the control unit 21 of the terminal 20A accepts input of the content and destination information relating to the destination of the content (A2). At this time, the destination information may include URL information relating to a specific URL 53 designated by the user A of the terminal 20A.

For example, when a specific symbol "@" is entered into input area 31 to specify (e.g., mention) a destination to notify of the receipt of content, and then URL 53 is specified (e.g., specified by an input operation) by user A, control unit 21 of terminal 20A sets the URL information of URL 53 as destination information for the content. Note that the URL information may include information for identifying URL 53, such as text information of URL 53, position information of URL 53 in chat room R, and identification information of URL 53 in chat room R.

At this time, the control unit 21 of the terminal 20A may display the target number information included in the specific URL information selected by the user A on the display unit 24, similar to the second embodiment. For example, the control unit 21 of the terminal 20A may request the server 10 to transmit the target number information included in the specific URL information. The control unit 11 of the server 10 calculates the number of users included in the specific URL information and transmits this number to the terminal 20A. As a result, the control unit 21 of the terminal 20A causes the display unit 24 to display the target number information included in the specific URL information.

Then, in response to user A's input operation on the send button 38, the control unit 21 of the terminal 20A transmits the first content 37 input by user A in the input area 31 and the destination information including the URL information to the server 10 (A3).

When the control unit 11 of the server 10 receives the first content 37 and the destination information including URL information from the terminal 20A, it transmits the first content 37 and the destination information to the terminals 20A-20C of the users A-C registered in the chat room R (B1). As a result, the control unit 21 of the terminal 20A displays the second display 39 based on the destination information and the first content 37 in the chat room R (A4), as shown in FIG. 5-3B. At this time, the second display 39 may display content indicating the destination information, such as "People who read https://www.************."

The control unit 21 of terminal 20B also displays a second display 39 based on the destination information and the first content 37 in the chat room R (C1). Then, the control unit 21 of terminal 20B controls a notification regarding the reception of the first content 37 based on the URL information indicating the destination information (C2).

At this time, the control unit 21 of the terminal 20B may acquire the selection history of user B for URL 53 in the chat room R from the storage unit 28 or the server 10 based on the URL information indicating the destination information. Then, the control unit 21 of the terminal 20B may determine whether or not user B corresponds to the person who read URL 53, that is, whether or not user B read the site indicated by URL 53, based on the acquired selection history for URL 53. Note that if there is a URL identical to URL 53 in the chat room R (if there are multiple URLs 53), it may be determined that user B corresponds to the person who read URL 53 if user B selected any one of the URLs 53. In this way, when the control unit 21 of the terminal 20B determines that user B corresponds to the person who read URL 53, it may notify the reception of the first content 37.

Similarly, the control unit 21 of terminal 20C causes a second display 39 based on the destination information and the first content 37 to be displayed in chat room R (D1). Then, the control unit 21 of terminal 20C controls a notification regarding the receipt of the first content 37 based on the URL information indicating the destination information (D2). At this time, if the control unit 21 of terminal 20C determines that user C does not correspond to the person who read URL 53, it does not notify the receipt of the first content 37.

<Effects of the Fifth Modification (1)>
In the fifth modified example (1), the destination information includes URL information about URL 53 specified by user A of terminal 20A in chat room R (not limited to this, but an example of information about URL 53).

As an example of the effect of this configuration, user A of terminal 20A can easily set the user who reads URL 53 as the destination to be notified of the receipt of first content 37.

<Fifth Modification (2)>
In the fifth modified example (1), the destination information includes URL information related to URL 53 specified by user A of terminal 20A in chat room R, but is not limited to this as long as it includes information related to specific content.

In the fifth variant (2), the destination information includes image information regarding a specific image specified by user A of terminal 20A in chat room R.

First, as in the fifth modified example (1), the control unit 21 of the terminal 20A causes the display unit 24 to display an input area 31 for inputting content in response to an input operation by the user A, as shown in FIG. 5-4A (A1). Then, the control unit 21 of the terminal 20A accepts input of the content and destination information regarding the destination of the content (A2). At this time, the destination information may include image information regarding a specific image 55 designated by the user A of the terminal 20A.

For example, when a specific symbol "@" is entered in input area 31 to specify a destination to notify of the receipt of content (e.g., a mention), and then a specific image 55 is specified by user A (e.g., by inputting the transfer button), control unit 21 of terminal 20A sets the image information of that image as destination information for the content. Note that the image information may include information for identifying image 55, such as location information of image 55 in chat room R, and identification information of image 55 in chat room R.

At this time, the control unit 21 of the terminal 20A may display information on the number of subjects who viewed the specific image 55 selected by the user A on the display unit 24, as in the second embodiment. For example, the control unit 21 of the terminal 20A may request the server 10 to transmit information on the number of subjects who viewed the specific image 55. The control unit 11 of the server 10 calculates the number of users who viewed the specific image 55, and transmits this number to the terminal 20A. As a result, the control unit 21 of the terminal 20A displays information on the number of subjects who have registered specific attribute information on the display unit 24.

Then, in response to user A's input operation on the send button 38, the control unit 21 of the terminal 20A transmits the first content 37 input by user A in the input area 31 and the destination information including the image information to the server 10 (A3).

When the control unit 11 of the server 10 receives the first content 37 and the destination information including the image information from the terminal 20A, it transmits the first content 37 and the destination information to the terminals 20A to 20C of the users A to C registered in the chat room R (B1). As a result, the control unit 21 of the terminal 20A displays the second display 39 based on the destination information and the first content 37 in the chat room R (A4), as shown in FIG. 5-4B. At this time, the second display 39 may display content indicating the destination information, such as "People who viewed image 55." In addition, the second display 39 may have the image 55 attached to it.

The control unit 21 of the terminal 20B also displays the second display 39 based on the destination information and the first content 37 in the chat room R (C1). The control unit 21 of the terminal 20B then controls a notification regarding the reception of the first content 37 based on the image information indicating the destination information (C2).

At this time, the control unit 21 of terminal 20B may acquire a selection history for image 55 of user B in chat room R from the storage unit 28 or server 10 based on image information indicating destination information. Then, based on the acquired selection history for image 55, the control unit 21 of terminal 20B may determine whether or not user B corresponds to "a person who viewed image 55," i.e., whether or not user B enlarged image 55 and viewed it. If the control unit 21 of terminal 20B determines that user B corresponds to a person who viewed image 55, it may notify the reception of first content 37.

Similarly, the control unit 21 of terminal 20C causes a second display 39 based on the destination information and the first content 37 to be displayed in chat room R (D1). Then, the control unit 21 of terminal 20C controls a notification regarding the reception of the first content 37 based on image information indicating the destination information (D2). At this time, if the control unit 21 of terminal 20C determines that user C is not one of the people who viewed image 55, it does not notify the reception of the first content 37.

<Effects of the Fifth Modification (2)>
In the fifth modified example (2), the destination information includes image information about an image 55 specified by a user A of terminal 20A in chat room R (not limited to this, but is an example of information about image 55).

As an example of the effect of this configuration, user A of terminal 20A can easily set the user who viewed image 55 as the destination to be notified of the receipt of first content 37.

<Fifth Modification (3)>
In the fifth modified examples (1) and (2), the destination information includes URL information or image information, but is not limited to this.

In the fifth variant (2), the destination information includes message information regarding a specific message specified by user A of terminal 20A in chat room R.

First, as in the fifth modified example (1), the control unit 21 of the terminal 20A causes the display unit 24 to display an input area 31 for inputting content in response to an input operation by the user A, as shown in FIG. 5-5A (A1). Then, the control unit 21 of the terminal 20A accepts input of the content and destination information regarding the destination of the content (A2). At this time, the destination information may include message information regarding a specific message 57 designated by the user A of the terminal 20A.

For example, when a specific symbol "@" is entered in the input area 31 to specify a destination to notify of the receipt of content (e.g., a mention), and then a specific message 57 is specified (e.g., specified by an input operation) by user A, the control unit 21 of terminal 20A sets the message information of the specific message 57 as destination information for the content. Note that the message information may include information for identifying the message 57, such as text information of the message 57, position information of the message 57 in chat room R, and identification information of the message 57 in chat room R.

At this time, the control unit 21 of the terminal 20A may display information on the number of targets who read the specific message 57 selected by the user A on the display unit 24, as in the second embodiment. For example, the control unit 21 of the terminal 20A may request the server 10 to transmit information on the number of targets who read the specific message 57. The control unit 11 of the server 10 calculates the number of users who read the specific message 57 and transmits this number to the terminal 20A. As a result, the control unit 21 of the terminal 20A causes the display unit 24 to display information on the number of targets who read the specific message 57.

Then, in response to user A's input operation on the send button 38, the control unit 21 of the terminal 20A transmits the first content 37 input by user A in the input area 31 and the destination information including the message information to the server 10 (A3).

When the control unit 11 of the server 10 receives the first content 37 and the destination information including the message information from the terminal 20A, it transmits the first content 37 and the destination information to the terminals 20A to 20C of the users A to C registered in the chat room R (B1). As a result, the control unit 21 of the terminal 20A displays the second display 39 based on the destination information and the first content 37 in the chat room R (A4), as shown in FIG. 5-5B. At this time, the second display 39 may display content indicating the destination information, such as "People who read message 57." Furthermore, the entire content of the message 57 may be displayed, or only a portion of the content may be displayed.

The control unit 21 of the terminal 20B also displays the second display 39 based on the destination information and the first content 37 in the chat room R (C1). The control unit 21 of the terminal 20B then controls a notification regarding the reception of the first content 37 based on the message information specified in the destination information (C2).

At this time, the control unit 21 of the terminal 20B may acquire the selection history for the message 57 of the user B in the chat room R from the storage unit 28 or the server 10 based on the message information indicating the destination information. Then, the control unit 21 of the terminal 20B may determine whether or not the user B corresponds to the person who read the message 57, that is, whether or not the user B actually displayed the message 57, based on the acquired selection history for the message 57. At this time, the control unit 21 of the terminal 20B may make a determination based on the impression information of the specific message 57. For example, the impression information may or may not be information indicating whether or not an input operation (e.g., a click) has been performed on the specific message 57. Also, the impression information may be generated as one impression when at least a part of the specific message 57 is displayed on the display unit 24, and may be determined based on the degree of the impression. Also, the impression information may or may not be information indicating whether or not the entire specific message 57 has been displayed on the display unit 24. In this way, if the control unit 21 of the terminal 20B determines that the person who read the message 57 is user B, the control unit 21 may notify the user of the receipt of the first content 37.

Similarly, the control unit 21 of terminal 20C causes a second display 39 based on the destination information and the first content 37 to be displayed in chat room R (D1). Then, the control unit 21 of terminal 20C controls a notification regarding the receipt of the first content 37 based on the message information indicating the destination information (D2). At this time, if the control unit 21 of terminal 20C determines that user C does not correspond to the person who read the message 57, it does not notify the receipt of the first content 37.

<Effects of the Fifth Modification (3)>
In the fifth modified example (3), the destination information includes message information about a message 57 specified in chat room R by user A of terminal 20A (not limited to this, an example of information about message 57).

As an example of the effect of such a configuration, user A of terminal 20A can easily set the user who actually read message 57 as the destination to be notified of the receipt of first content 37.

Sixth Embodiment
In the first to fifth embodiments, the control unit 21 of the terminal 20A transmitted one-way first content 37 to the terminals 20B and 20C of the users B and C registered in the chat room R, but may also transmit content to which a response can be made.

In the sixth embodiment, the control unit 21 of the terminal 20A transmits the second content to which the user can respond and the destination information to the terminals 20B and 20C of the users B and C who are registered in the chat room R. When the control unit 21 of the terminals 20B and 20C receives the second content and the destination information via the communication unit 22, it causes the display unit 24 to display the second content to which only the target user of the destination information can respond, based on the destination information.

The same components as those in the first to fifth embodiments are designated by the same reference numerals and will not be described again. The contents described in the sixth embodiment are applicable to any of the other embodiments.

First, as in the first embodiment, the control unit 21 of the terminal 20A receives content and destination information related to the destination of the content (A2), as shown in FIG. 1-7. At this time, the control unit 21 of the terminal 20A may receive input of second content to which only the user who is the target of the destination information can respond. For example, as shown in FIG. 6-1, the second content 58 may include a questionnaire to which the user who is the target of the destination information is asked to respond. The second content 58 may be provided with an answer column 59 in which the user who is the target of the destination information answers. Here, the second content 58 is assumed to be composed of a questionnaire to which people in the vicinity of the stadium Ka are asked to vote. The answer column 59 may also be configured to allow the user to input whether or not they will vote.

The control unit 21 of the terminal 20A may also accept input of location information including specific location information 34 and range information 35 as destination information, for example as shown in FIG. 1-8B. For example, the specific location information 34 may be set to the location of "Stadium Ka." Furthermore, the range information 35 may be set to a specific range centered on the location of "Stadium Ka."

When the second content 58 and the destination information including the location information are input, the control unit 21 of the terminal 20A transmits the second content 58 and the destination information to the server 10 in response to the input operation of the user A on the send button 38 (A3). Then, when the control unit 11 of the server 10 receives the second content 58 and the destination information from the terminal 20A, it transmits the second content 58 and the destination information to the terminals 20A-20C of all the users A-C registered in the chat room R (B1). As a result, the communication units 22 of the terminals 20A-20C receive the second content 58 input by the user A of the terminal 20A among the multiple terminals 20A-20C, and the destination information regarding the destination of the content input by the user A of the terminal 20A.

When the control unit 21 of the terminal 20B receives the second content 58 and the destination information from the server 10, the control unit 21 displays the second content 58, which can only be responded to by the target user of the destination information, on the display unit 24 based on the destination information (C1). For example, as shown in FIG. 6-2A, the control unit 21 of the terminal 20B may display the second display 39 based on the destination information and the second content 58 in the chat room R. Then, as shown in FIG. 6-2B, the control unit 21 of the terminal 20B may enlarge and display the second content 58 on the display unit 24 in response to an input operation by user B on the second content 58. At this time, if the position information indicating the destination information includes user B of the terminal 20B (user B is located inside the range information 35), the control unit 21 of the terminal 20B displays the second content 58 in a responsive manner. As a result, the control unit 21 of the terminal 20B accepts a vote from user B in the answer column 59. When user B enters a response in the response field 59, the control unit 21 of terminal 20B transmits the response result to the server 10.

Similarly, when the control unit 21 of the terminal 20C receives the second content 58 and the destination information from the server 10, the control unit 21 causes the display unit 24 to display the second content 58, to which only the user targeted by the destination information can respond, based on the destination information (D1). Here, if the location information indicating the destination information does not include user C of the terminal 20C (user C is located outside the range information 35), the control unit 21 of the terminal 20C causes the second content 58 to be displayed in response addition.

When the control unit 11 of the server 10 receives a response result from the terminal 20 of a user who is the target of the destination information, including user B, the control unit 11 of the server 10 may perform a calculation process on the response result and transmit it to the terminal 20A.

In this embodiment, the control unit 21 of the terminals 20B and 20C determines whether the second content 58 and the destination information are the target of the destination information at the timing when they receive the second content 58 and the destination information from the server 10, but the control unit 21 may continuously determine whether the destination information is the target. For example, after determining that the location information indicating the destination information does not include user C of the terminal 20C (user C is located outside the range information 35), the control unit 21 of the terminal 20C may continue to acquire its own location information until a predetermined time (for example, the time when the event ends). Then, when the control unit 21 of the terminal 20C determines that user C is included in the location information indicating the destination information, the control unit 21 may display the second content 58 in a responsive manner.

Effects of the Sixth Embodiment
In the sixth embodiment, the communication unit 22 of the terminal 20B receives second content 58 input by a user A of the terminal 20A among the multiple terminals 20A to 20C, and destination information regarding the destination of the content input by the user A of the terminal 20A. Then, the control unit 21 of the terminal 20B causes the display unit 24 to display second content 58 to which only the user who is the target of the destination information can respond, based on the destination information.

As an example of the effect of this configuration, user B, who is the target of the destination information, can easily respond to the second content 58.

Seventh Embodiment
In the first to sixth embodiments, the control unit 21 of the terminals 20B and 20C notifies all users targeted by the destination information of the reception of the content, but the notification may be restricted for certain users.

In the seventh embodiment, the control units 21 of the terminals 20B and 20C control notifications regarding content reception based on the reception of destination information and notification settings by the users B and C. For example, if the users B and C have set the function of notifications regarding content reception to OFF, the control units 21 of the terminals 20B and 20C may not notify the reception of the first content 37 even if they are determined to be the target of the destination information.

The same components as those in the first to sixth embodiments are designated by the same reference numerals and will not be described again. The contents described in the seventh embodiment are also applicable to any of the other embodiments.

<Information Processing>
FIG. 7A is a flowchart showing an example of the flow of processes executed by each device in this embodiment.

First, as in the first embodiment, when the control unit 11 of the server 10 receives the first content 37 and the destination information from the terminal 20A, it transmits the first content 37 and the destination information to the terminals 20A to 20C of all users A to C registered in the chat room R (B1). Then, when the control unit 21 of the terminal 20B receives the first content 37 and the destination information from the server 10, it displays the first content 37 in the chat room R (C1). Note that the processing of the terminal 20C is the same as that of the terminal 20B, so the processing of the terminal 20B will be described below.

At this time, the control unit 21 of terminal 20B determines whether or not a destination has been specified to notify the reception of the first content 37 based on the destination information (C71). If the control unit 21 of terminal 20B determines that a destination has been specified, it notifies the reception of the first content 37 (C76). On the other hand, if the control unit 21 of terminal 20B determines that a destination has been specified, it causes the display unit 24 to display a second display 39 based on the destination information, as shown in FIG. 1-10 (C72).

The control unit 21 of terminal 20B then determines whether or not user B is included in the destination information, for example, whether or not user B is included in the location information of the destination information (C73). If user B is not included in the destination information, the control unit 21 of terminal 20B disables the notification of the reception of the first content 37 (C74). On the other hand, if user B is included in the destination information, the control unit 21 of terminal 20B determines whether or not the notification setting regarding the reception of content is ON (C75).

In general, notification settings 60 regarding content reception are provided so that user B can select ON or OFF, as shown in FIG. 7-2. These notification settings 60 are used to set whether or not to notify user B of the receipt of content when content is received with a specified destination (e.g., a mention) and the destination includes user B.

If the control unit 21 of terminal 20B determines that the notification setting 60 is OFF, the process proceeds to step C74, where the control unit 21 disables the notification of the reception of the first content 37. For example, even if the location information indicating the destination information includes user B of terminal 20B (user B is located inside the range information 35), if the control unit 21 of terminal 20B determines that the notification setting 60 is OFF, the control unit 21 of terminal 20B will not notify the reception of the first content 37. On the other hand, if the control unit 21 of terminal 20B determines that the notification setting 60 is ON, the control unit 21 notifies the reception of the first content 37 (C76), as shown in FIG. 1-12A.

Effects of the Seventh Embodiment
In the seventh embodiment, the control unit 21 of the terminal 20B controls notifications regarding the reception of content, based on the reception of destination information and the notification settings 60 by the user B of the terminal 20B.

As an example of the effect of such a configuration, user B of terminal 20B can easily select whether or not to notify the reception of content for which destination information has been specified.
For example, if user B does not need notifications of mentions, he or she can easily turn them off in his or her notification settings 60.

Eighth Embodiment
In the first to seventh embodiments, the control units 21 of the terminals 20B and 20C determined whether or not users B and C were the targets of the destination information, but this is not limited to the above as long as the users who are the targets of the destination information can be notified of the reception of content.

In the eighth embodiment, the control unit 11 of the server 10 transmits control information for controlling notification of content to the terminal 20B of the user B that is the subject of the destination information, among the multiple terminals 20B and 20C, based on the destination information. As a result, the control unit 21 of the terminal 20B may notify the reception of the first content 37 based on the control information.

The same components as those in the first to seventh embodiments are designated by the same reference numerals and will not be described again. The contents described in the eighth embodiment are applicable to any of the other embodiments.

<Functional configuration>
8A is a diagram showing an example of functions realized by the communication unit 14 of the server 10 in this embodiment. The communication unit 14 includes, by way of example and not limitation, a communication main processing unit 141, a reception processing unit 142, and a transmission processing unit 143.

The communication main processing unit 141 has a function of executing communication main processing, which is processing for sending and receiving information between the terminals 20A to 20C under the control of the control unit 11.

The reception processing unit 142 has a function of executing a reception process under the control of the control unit 11, which is a process of receiving the first content input by user A of terminal 20A included in the multiple terminals 20A to 20C and destination information regarding the destination of the content.

The transmission processing unit 143 has a function to execute a transmission process, which is a process of transmitting control information for controlling notification of content to a terminal 20 of a user who is the target destination among multiple terminals 20A to 20C, based on the destination information, under the control of the control unit 11.

Figure 8-2 is a diagram showing an example of information stored in the memory unit 15 of the server 10 in this embodiment. By way of example and not limitation, the memory unit 15 stores a server main processing program 151 that is read by the control unit 11 and executed as server main processing.

In addition, the server main processing program 151 includes, as a subroutine program, a reception processing program 1511, which is read by the control unit 11 and executed as reception processing, but is not limited to this example.

The server main processing program 151 also includes, as a subroutine program, a transmission processing program 1512, which is read by the control unit 11 and executed as a transmission process, but is not limited to this example.

Figure 8-3 is a diagram showing an example of the functions realized by the control unit 11 of the server 10 in this embodiment. The control unit 11 has, by way of example and not limitation, a server main processing unit 111, a receiving processing unit 112, and a transmitting processing unit 113.

The server main processing unit 111 has the function of executing server main processing, which is processing for comprehensively controlling the server 10, in accordance with the server main processing program 151 stored in the memory unit 15.

The reception processing unit 112 executes a reception process to receive the first content input by user A of terminal 20A included in the multiple terminals 20A to 20C and destination information regarding the destination of the content, according to the reception processing program 1511 stored in the memory unit 15.

The transmission processing unit 113 executes a reception process in accordance with the transmission processing program 1512 stored in the memory unit 15, which receives control information for controlling the notification of content from the communication unit 14 and transmits it to the terminal 20 of the user who is the destination among the multiple terminals 20A to 20C, based on the destination information.

<Information Processing>
FIG. 8D is a flowchart showing an example of the flow of processing executed by each device in this embodiment.

First, as in the first embodiment, the control unit 21 of the terminal 20A transmits the first content 37 and destination information input by the user A in the input area 31 to the server 10 in response to the user A's input operation on the send button 38, as shown in FIG. 1-9 (A3). As a result, the communication unit 14 of the server 10 receives the first content 37 input by the user A of the terminal 20A included in the multiple terminals 20A to 20C, and the destination information regarding the destination of the content.

When the control unit 11 of the server 10 receives the first content 37 and the destination information from the terminal 20A, it requests user information corresponding to the destination information from the terminals 20B and 20C registered in the chat room R (B81). For example, as shown in FIG. 1-8B, when location information is specified as the destination information, the control unit 11 of the server 10 may request the location information of users B and C from the terminals 20B and 20C.

When the control unit 21 of terminal 20B receives a request for user B's location information from the server 10, it acquires its own location information and transmits the location information to the server 10 as user information (C81). The control unit 21 of terminal 20B may acquire its own specific location information, for example, using a positioning system such as GPS. Similarly, when the control unit 21 of terminal 20C receives a request for user C's location information from the server 10, it acquires its own location information and transmits the location information to the server 10 as user information (D81).

Next, when the control unit 11 of the server 10 receives location information from terminals 20B and 20C as user information corresponding to the destination information, the control unit 11 determines the users who are the targets of the destination information based on the location information of users B and C (B82). For example, the control unit 11 of the server 10 may determine the users who are the targets of the destination information based on whether the location information of users B and C is included in the location information specified in the destination information. Here, it is assumed that the control unit 11 of the server 10 has determined that user B is the target of the destination information.

The control unit 11 of the server 10 transmits the first content 37, the destination information, and control information for controlling the notification of the content to the terminal 20B based on the determination result (B83). In this way, the control unit 11 of the server 10 transmits the control information for controlling the notification of the content to the terminal 20B of the target destination user B among the multiple terminals 20A to 20C based on the destination information by the communication unit 14. Meanwhile, the control unit 11 of the server 10 transmits the first content 37 and the destination information to the terminals 20A and 20C based on the determination result (B84). Note that the control information may be generated in advance in the terminal 20 to notify the reception of the content, or may be generated according to the determination result.

At this time, the order of the process (B83) of transmitting the first content 37, destination information, and control information to the terminal 20B of user B, who is the target of the destination information, and the process (B84) of transmitting the first content 37 and destination information to the terminals 20A and 20C of users A and C, who are not the target of the destination information, is not particularly limited. For example, the control unit 11 of the server 10 may transmit the first content 37, destination information, and control information to the terminal 20B, and then transmit the first content 37 and destination information to the terminals 20A and 20C. In addition, the control unit 11 of the server 10 may transmit the first content 37 and destination information to the terminals 20A and 20C, and then transmit the first content 37, destination information, and control information to the terminal 20B. In addition, the control unit 11 of the server 10 may simultaneously transmit the first content 37, destination information, and control information to the terminal 20B and the first content 37 and destination information to the terminals 20A and 20C.

When the control unit 21 of terminal 20B receives the first content 37, the destination information, and the control information from the server 10, it displays the first content 37 and a second display 39 based on the destination information in the chat room R, as shown in FIG. 1-12A (C1). Then, the control unit 21 of terminal 20B controls a notification regarding the reception of the first content 37 based on the control information (C2).

For example, the control unit 21 of the terminal 20B may or may not control the speaker 26 to output the received sound 40a. The control unit 21 of the terminal 20B may or may not activate a vibration function 40b to vibrate the terminal 20B. The control unit 21 of the terminal 20B may or may not control the display unit 24 to highlight 40c (e.g., display in bold) the first content 37 or the second display 39. The control unit 21 of the terminal 20B may or may not use a notification function in the chat room R application to display a notification message notifying the reception of the first content, such as a notification message such as "You've been mentioned."

On the other hand, when the control unit 21 of terminal 20C receives the first content 37 and the destination information from the server 10, it displays the first content 37 and a second display 39 based on the destination information in chat room R, as shown in FIG. 1-12B (D1). At this time, the control unit 21 of terminal 20C does not notify the reception of the first content 37 because it has not received the control information.

In this embodiment, the control unit 11 of the server 10 sent the control information only to terminal 20B, but if multiple users B and C are determined to be the targets of the destination information, the control information may be sent to multiple terminals 20B and 20C. As a result, the control unit 11 of the server 10 sends the control information to terminal 20B of user B, who is the target destination, and terminal 20C of user C, among the multiple terminals 20A to 20C, based on the destination information. When the control units 21 of terminals 20B and 20C receive the control information, they each control the notification regarding the reception of the first content 37 based on the control information.

In this embodiment, in response to receiving the first content 37 and the destination information transmitted from terminal 20A, terminals 20B and 20C are requested to transmit user information (B81), but this is not limiting as long as the user information of terminals 20B and 20C can be obtained. For example, the control unit 11 of the server 10 may request terminals 20B and 20C to transmit user information at a predetermined timing. This allows the control unit 11 of the server 10 to know in advance the user information of users B and C registered in chat room R. Then, when the control unit 11 of the server 10 receives the first content 37 and the destination information from terminal 20A, it determines the user who is the target of the destination information based on the previously obtained user information of terminals 20B and 20C (B82).

In addition, in this embodiment, the control unit 11 of the server 10 obtains the user information of the terminals 20B and 20C by requesting the terminals 20B and 20C to transmit the user information, but this is not limited as long as the user information of the terminals 20B and 20C can be obtained. For example, the control units 21 of the terminals 20B and 20C may automatically transmit their own user information to the server 10 (for example, transmit the user information at a predetermined interval). This allows the control unit 11 of the server 10 to always be aware of the user information of the users B and C registered in the chat room R. Then, when the control unit 11 of the server 10 receives the first content 37 and the destination information from the terminal 20A, it determines the user that is the target of the destination information based on the user information of the terminals 20B and 20C that was previously obtained (B82).

In addition, in this embodiment, the control unit 11 of the server 10 transmits the first content 37 and the destination information to terminal 20B and terminals 20A and 20C separately, but this is not limited to this. For example, the control unit 11 of the server 10 may transmit the first content 37 and the destination information to terminals 20A to 20C of all users A to C registered in chat room R, and transmit the control information to terminal 20B of user B who is the subject of the destination information. The order of the process of transmitting the first content 37 and the destination information to terminals 20A to 20C and the process of transmitting the control information to terminal 20B is not particularly limited.

Effects of the Eighth Embodiment
In the eighth embodiment, the communication unit 14 of the server 10 receives the first content 37 input by the user A of the terminal 20A included in the multiple terminals 20A to 20C and destination information regarding the destination of the content. Then, the control unit 11 of the server 10 transmits, based on the destination information, control information for controlling notification of the content to the terminal 20B of the user who is the destination among the multiple terminals 20A to 20C, by the communication unit 14.

As an example of the effect of this configuration, the control unit 21 of the terminal 20B can easily notify the reception of the first content 37.

In the eighth embodiment, the control unit 11 of the server 10 transmits control information to the terminal 20B of user B and the terminal 20C of user C, which are the destinations, among the multiple terminals 20A to 20C, based on the destination information.

One example of the effect of this configuration is that multiple terminals 20B and 20C can easily notify each other of the reception of the first content 37.

Ninth embodiment
In the ninth embodiment, the control unit 11 of the server 10 controls, based on call conditions preset by the user A of the terminal 20A, the user B among the users A to C of the terminals 20A to 20C included in the chat room who satisfies the call conditions to be able to participate in the call. For example, the control unit 11 of the server 10 may control the terminal 20B of the user B to be able to participate in the call by transmitting participation information for participating in the call. Then, based on the control to enable the user B to participate in the call, the control unit 11 processes at least some of the terminals 20A to 20C, for example, the call between the user A and the user B.

The same components as those in the first to eighth embodiments are designated by the same reference numerals and will not be described again. The contents described in the ninth embodiment are also applicable to any of the other embodiments.

<Functional configuration>
(1) Functional configuration of the server Fig. 9-1 is a diagram showing an example of information stored in the storage unit 15 of the server 10 in this embodiment. The storage unit 15 stores, by way of example and not limitation, a server main processing program 151 that is read out by the control unit 11 and executed as a server main processing program.

The server main processing program 151 also includes, as a subroutine program, a participating user control processing program 1513, which is read by the control unit 11 and executed as participating user control processing, but is not limited to this example.

The server main processing program 151 also includes, as a subroutine program, a call processing program 1514, which is read by the control unit 11 and executed as call processing, but is not limited to this example.

Figure 9-2 is a diagram showing an example of the functions realized by the control unit 11 of the server 10 in this embodiment. The control unit 11 has, by way of example and not limitation, a server main processing unit 111, a participating user control processing unit 114, and a call processing unit 115.

The server main processing unit 111 has the function of executing server main processing, which is processing for comprehensively controlling the server 10, in accordance with the server main processing program 151 stored in the memory unit 15.

The participating user control processing unit 114 controls which users can participate in a call among users A to C of each of the multiple terminals 20A to 20C included in the chat room, based on the set call conditions, in accordance with the participating user control processing program 1513 stored in the memory unit 15.

Here, the call conditions are conditions for extracting a call destination from among multiple users A to C registered in chat room R, and may be composed of, for example, the specification of a specific user, location information, attribute information, etc.

The call processing unit 115 processes calls made by at least some of the multiple terminals 20A to 20C under the control of users who can participate in the calls, in accordance with the call processing program 1514 stored in the memory unit 15.

Here, the call can be any call between multiple users, such as a voice call (e.g., a telephone call) or a video call.

<Information Processing>
FIG. 9C is a flowchart showing an example of the flow of processing executed by each device in this embodiment.

First, the control unit 21 of terminal 20A, in response to an input operation by user A, causes the display unit 24 to display a chat room R in which multiple users, including users A to C, are registered (A91). Similarly, the control unit 21 of terminal 20B, in response to an input operation by user B, causes the display unit 24 to display a chat room R (C91). Furthermore, the control unit 21 of terminal 20C, in response to an input operation by user C, causes the display unit 24 to display a chat room R (D91). In this chat room R, content M such as messages transmitted and received between multiple terminals 20A to 20C is displayed, as shown in FIG. 9-4A.

Then, the control unit 21 of the terminal 20A sets call conditions for extracting a call destination from among the multiple users A to C registered in the chat room R based on the input operation of the user A (A92). Here, the call conditions may be set by, for example, designating a specific user as the call destination from among the multiple users A to C registered in the chat room R. For example, when the call button 71a for voice calls is selected by the user A, the control unit 21 of the terminal 20A may display a selection screen 72 on the display unit 24 as shown in FIG. 9-4B. This selection screen 72 is provided with selection buttons 73 that can directly select each of the multiple users B and C registered in the chat room R, and a specific user is selected as the call destination according to the input of the user A to the selection button 73. Here, it is assumed that the user A has selected the user B as the call destination. As a result, the control unit 21 of the terminal 20A sets the call conditions for designating the user B as the call destination.

When user A operates the call request button 74 on the selection screen 72, the control unit 21 of the terminal 20A transmits a call request to the server 10 requesting that the call be processed based on the set call conditions (A93). As a result, the control unit 11 of the server 10 receives a call request including the call conditions from the terminal 20A. In this way, the call conditions may include conditions related to user B specified by user A of the terminal 20A who initiated the call.

When the control unit 11 of the server 10 receives a call request from the terminal 20A, it controls user B, who satisfies the call conditions and can participate in the call, from among the multiple terminals 20A to 20C included in the chat room R, based on the call conditions set in the terminal 20A (B91). Specifically, the control unit 11 of the server 10 extracts user B, who satisfies the set call conditions, from among the users A to C included in the chat room R. Then, the control unit 11 of the server 10 may control the terminal 20B so that user B, who satisfies the call conditions, can make a call. For example, the control unit 11 of the server 10 may transmit participation information for participating in the call to the terminal 20B of user B, who is able to participate in the call, from among the users A to C of each of the multiple terminals 20A to 20C, by the communication unit 14.

As shown in FIG. 9-5A, when the control unit 21 of terminal 20B receives participation information 75 from the server 10, the control unit 21 displays the participation information 75 in chat room R (C92). Here, the participation information 75 may be provided with a function for controlling terminal 20B to allow user B to participate in a call with user A, for example a join button 76 that allows user B to participate in a call with user A. When user B operates the join button 76, the control unit 21 of terminal 20B transmits a join request to the server 10 requesting that user B join the call with user A (C93).

On the other hand, the control unit 11 of the server 10 does not send participation information 75 to terminal 20C of user C, who does not meet the call conditions and is therefore unable to participate in the call. As a result, as shown in FIG. 9-5B, participation information 75 is not displayed in chat room R displayed on terminal 20C. In other words, user C of terminal 20C cannot request the server 10 to participate in the call with user A.

In this way, when the control unit 11 of the server 10 receives a participation request from terminal 20B based on control that allows user B to participate in the call, the control unit 11 processes the voice call between at least some of the multiple terminals 20A to 20C, i.e., the voice call between terminals 20A and 20B, based on the participation request (B92). As shown in FIG. 9-6, the control unit 21 of terminal 20B may display a call screen 77 on the display unit 24 in response to the call processing of the server 10. The call screen 77 may display, for example, icons 78 indicating users A and B who will participate in the call.

As a result, the control unit 11 of the server 10 establishes a call connection between the terminal 20A and the terminal 20B, and user A becomes able to make a voice call with user B who satisfies the call conditions. At this time, user C who does not satisfy the call conditions cannot participate in the call, so user A becomes able to selectively make a call with user B who satisfies the call conditions.

In this embodiment, when a call connection is established between terminal 20A and terminal 20B, the control unit 11 of the server 10 may notify terminal 20C of user C, who does not satisfy the call conditions, that a call has started between user A and user B. For example, as shown in FIG. 9-7, the control unit 11 of the server 10 may send a start notification 79 to terminal 20C indicating that a call has started between user A and user B. The control unit 11 of the server 10 may also send the start notification 79 to terminals 20A to C of all users A to C registered in chat room R. In this way, the control unit 11 of the server 10 can notify user C, who does not satisfy the call conditions, that a call has started between specific users.

In addition, in this embodiment, the control unit 11 of the server 10 transmits the participation information 75 only to the terminal 20B of user B, which satisfies the call conditions, but the present invention is not limited to this as long as the terminal 20C of user C can be made unavailable for calls. For example, the control unit 11 of the server 10 may transmit display information 75a indicating the display content of the participation information 75 to the terminal 20C, as shown in FIG. 9-8. This display information 75a does not have a function for participating in a call with user A, and no participation request is sent even if the position 76a corresponding to the join button 76 is operated. In this way, the control unit 11 of the server 10 can notify all users A to C registered in the chat room R that a call has started between specific users, while maintaining the terminal 20C of user C, which does not satisfy the call conditions, unavailable for calls.

In addition, in this embodiment, the control unit 11 of the server 10 processes a voice call between user A and user B, but is not limited to this as long as it can process a call between user A and user B. For example, when user A selects the call button 71b for a video call shown in FIG. 9-4A, the control unit 11 of the server 10 may process a video call between user A and user B who can join the call.

Effects of the ninth embodiment
In the ninth embodiment, the control unit 11 of the server 10 controls a user B who can participate in a call among users A to C of each of the multiple terminals 20A to 20C included in the chat room R, based on the set call conditions (not limited to, but an example of the set conditions). Then, the control unit 11 of the server 10 processes calls made by at least some of the multiple terminals 20A to 20C, based on the control of user B who can participate in the call.

As an example of the effect of such a configuration, user A of terminal 20A can talk to a specific user B among users B and C registered in chat room R.

In addition, in the ninth embodiment, the set call conditions include conditions regarding user B specified by user A of terminal 20A who initiated the call.

As an example of the effect of such a configuration, user A of terminal 20A can directly specify user B with whom he or she wishes to make a call.

In addition, in the ninth embodiment, the communication unit 14 of the server 10 transmits participation information 75 (not limited to, but an example of information for participating in a call) for participating in the call to the terminal 20B of user B, who is able to participate in the call, among users A to C of each of the multiple terminals 20A to 20C.

As an example of the effect of such a configuration, the control unit 21 of the terminal 20A can easily enable the terminal 20B of user B to join the call.

<Ninth Modification (1)>
In the ninth embodiment, the control unit 11 of the server 10 performed control so that user C, who does not satisfy the call conditions, cannot participate in the call, but it may also be performed so that user C can participate in at least a part of the call between users A and B.

In the ninth variant (1), for example, when a specific user who will participate in the call has consented in advance to the participation of user C, the control unit 11 of the server 10 transmits listening information for listening to the call to the terminal 20C of user C who cannot participate in the call.

First, as in the ninth embodiment, the control unit 11 of the server 10 processes a voice call between terminals 20A and 20B based on a participation request from terminal 20B, as shown in FIG. 9-6 (B92). Here, the control unit 11 of the server 10 may transmit listening information for listening to the call to terminal 20C of user C, who is not allowed to participate in the call, among users A to C of the multiple terminals 20A to 20C, via the communication unit 14.

For example, the start of a call between users A and B is made known to user C by a start notification 79 shown in FIG. 9-8. At this time, the control unit 21 of terminal 20C may send a join request to join the call to the server 10 based on an input operation by user C. When the control unit 11 of the server 10 receives the join request from terminal 20C, it determines whether or not a specific user joining the call, for example user A who started the call, has previously approved the participation of user C.

Here, in addition to the call destination settings (call condition settings) shown in FIG. 9-4B, it is assumed that user C is pre-registered in the server 10 as a user who can participate in all calls started by user A. When the control unit 11 of the server 10 determines that user C's participation has been approved in advance, it may transmit listening information 80 for listening to the call to the terminal 20C of user C who cannot participate in the call, as shown in FIG. 9-9. Here, the listening information 80 may be provided with a join button 81 that allows users A and B to listen to the calls. In response to an input operation on the join button 81, the control unit 21 of the terminal 20C transmits a join request to the server 10 requesting to listen to the call.

When the control unit 11 of the server 10 receives the participation request from the terminal 20C, it transmits the audio of the conversation between users A and B to the terminal 20C. This allows user C of the terminal 20C to hear the conversation between users A and B.

In this embodiment, the control unit 11 of the server 10 transmits listening information 80 for listening to the call to the terminal 20C, but may transmit viewing information for viewing the call to the terminal 20C. For example, when processing a video call between terminals 20A and 20B in step B92, the control unit 11 of the server 10 may transmit viewing information for viewing the call to the terminal 20C. Then, when the control unit 11 of the server 10 receives a participation request from the terminal 20C, it transmits the audio and video of the video call between users A and B to the terminal 20C. This allows user C of the terminal 20C to watch the video call between users A and B.

In addition, in this embodiment, the control unit 11 of the server 10 controls the call between users A and B so that user C can only listen or watch, but it may also control the call so that user C can participate in the call with users A and B. This allows user C of the terminal 20C to talk to users A and B.

<Effects of the ninth modified example (1)>
In the ninth variant example (1), the communication unit 14 of the server 10 transmits listening information 80 (not limited to this, but an example of information for listening to a call) for listening to the call, or viewing information (not limited to this, but an example of information for viewing a call) for watching the call to the terminal 20C of user C, who is unable to participate in the call, among users A to C of the multiple terminals 20A to 20C.

As an example of the effect of this configuration, user C, who cannot participate in a call, can easily join a call between user A and user B.

<Ninth Modification (2)>
In the ninth embodiment, the control unit 11 of the server 10 transmits participation information 75 as shown in FIG. 9-5A, for example, to control the user B to be able to participate in the call, but may transmit notification information regarding the call to the terminal 20B.

In the ninth variant (1), the communication unit 14 of the server 10 transmits notification information to the terminal 20B of user B who is available to join the call, indicating that the user B is available to join the call.

First, as in the ninth embodiment, the control unit 11 of the server 10 controls the terminal 20B to allow user B to participate in the call by transmitting participation information 75 based on the call conditions set by user A to the terminal 20B (B91). At this time, the control unit 11 of the server 10 may transmit notification information regarding a notification indicating the call to the terminal 20B of user B who is able to participate in the call, among users A to C of each of the multiple terminals 20A to 20C, by the communication unit 14.

For example, the control unit 11 of the server 10 may transmit notification information to terminal 20B notifying the reception of the participation information 75, i.e., notifying that it is possible to join the call. When the control unit 21 of terminal 20B receives the participation information 75 and the notification information from the server 10, it displays the participation information 75 in the chat room R (C92), as shown in FIG. 9-10. Then, the control unit 21 of terminal 20B notifies the reception of the participation information 75 based on the notification information.

For example, the control unit 21 of terminal 20B may or may not control the speaker 26 to output the receiving sound 82a based on the notification information. Also, the control unit 21 of terminal 20B may or may not activate the vibration function 82b to vibrate terminal 20B. Also, the control unit 21 of terminal 20B may or may not display a notification message notifying the reception of participation information 75, such as a notification message such as "User A has started a group call," using a notification function in the chat room R application.

Then, in response to user B's input operation on the join button 76, the control unit 21 of terminal 20B sends a join request to the server 10 requesting that the user join the call with user A (C93).

<Effects of the ninth modified example (2)>
In the ninth variant example (2), the communication unit 14 of the server 10 transmits notification information (not limited to this, but an example of information relating to the notification) regarding a notification indicating a call to the terminal 20B of a user B, who is able to participate in the call, among the users A to C of each of the multiple terminals 20A to 20C.

As an example of the effect of such a configuration, user B of terminal 20B can easily understand that he or she can join a call with user A.

Tenth Embodiment
In the ninth embodiment, the call conditions are set by user A of terminal 20A, which initiated the call, directly specifying a specific user, as shown in FIG. 9-4B, but the present invention is not limited to this as long as the user to be the destination of the call can be specified.

In the tenth embodiment, the call conditions may include information about the user to be called, such as location information and attribute information of the terminal 20.

The same components as those in the first to ninth embodiments are designated by the same reference numerals and will not be described again. The contents described in the tenth embodiment are also applicable to any of the other embodiments.

<Information Processing>
FIG. 10A is a flowchart showing an example of the flow of processes executed by each device in this embodiment.

First, similarly to the ninth embodiment, the control unit 21 of the terminal 20A sets call conditions for extracting call destinations from among multiple users A to C registered in the chat room R (A92). Here, the call conditions may include location information related to the location.

For example, the control unit 21 of the terminal 20A may display a location setting button 83 for setting location information as a call condition on the selection screen 72 as shown in FIG. 10-2. Then, the control unit 21 of the terminal 20A may display a location specification screen 33 as shown in FIG. 10-3A in response to an input operation by the user A on the location setting button 83. The location specification screen 33 may include a specified location search section 33a, a search result display section 33b, a location information display section 33c, and a position determination button 33d. The specified location search section 33a searches for location information specified by the user A, and may be configured to allow, for example, a search keyword to be input. For example, a specific event (such as a match of soccer team K) or the name of the event venue (such as stadium Ka) may be input into the specified location search section 33a.

For example, when the search keyword "stadium Ka" is input to the specified location search unit 33a, the control unit 21 of the terminal 20A searches for location information based on the search keyword and displays the search results on the search result display unit 33b. Then, when a specific search result "stadium Ka" corresponding to the search keyword is selected by user A from among the search results displayed on the search result display unit 33b, the control unit 21 of the terminal 20A displays the location information of the stadium Ka on the location information display unit 33c. Here, the location information display unit 33c may display a map image of the area around the stadium Ka. That is, the control unit 21 of the terminal 20A displays a map image including the location information of the stadium Ka on the display unit 24.

Here, the location information may include specific location information 34 indicating a specific location (e.g., the location of stadium Ka). The specific location information 34 may be composed of, for example, information on the latitude and longitude of the specific location, and information indicating the location of the specific location (e.g., an address, etc.).

At this time, the control unit 21 of the terminal 20A may set the specific position information 34 based on an input by the user A to the map image. For example, the control unit 21 of the terminal 20A may change the position of the specific position information 34 on the map image based on an input by the user A to the map image. This adjusts the position of the specific position information 34 to a position desired by the user A. Then, the control unit 21 of the terminal 20A determines the position of the specific position information 34 in response to the input operation of the user A on the position determination button 33d.

The location information may also include range information indicating a specific range. For example, when the position determination button 33d is operated, the control unit 21 of the terminal 20A may display range information 35 indicating the specific range on the map image as shown in FIG. 10-3B. The range information 35 may be configured, for example, in a circular shape and displayed so as to surround the specific range centered on the specific location information 34.

Here, the control unit 21 of the terminal 20A may set the range information 35 based on the input by the user A to the map image. For example, the control unit 21 of the terminal 20A may change the position, diameter, or shape of the range information 35 in response to the input operation by the user A to the map image. Then, when the range information 35 is set, the control unit 21 of the terminal 20A may display the value of the range information 35, for example, displaying "within 3 km". In addition, the control unit 21 of the terminal may obtain the target number information 42 (the number of users present inside the range information 35) included in the range information 35 from the server 10, and display the target number information 42 on the display unit 24.

In this way, specific location information 34 and range information 35 are set by user A as location information of the target person of the call condition. That is, the location information includes specific location information 34 and range information 35. Note that the location information may be set by either specific location information 34 or range information 35, for example, only range information 35. The control unit 21 of terminal 20A may set the location information including specific location information 34 and range information 35 as the call condition for extracting the target person of the call destination in response to an input operation of user A on the position designation button 33e.

Then, the control unit 21 of the terminal 20A transmits a call request to the server 10 in response to the input operation of the user A, requesting that the call be processed based on the set call conditions (A93). In this manner, the call conditions may include conditions under which a specific user included in a location (e.g., specific location information 34, range information 35, etc.) designated by the user A of the terminal 20A can participate in the call.

When the control unit 11 of the server 10 receives the call request, it requests the terminals 20B and 20C of users B and C registered in chat room R to transmit user information corresponding to the call conditions (B101). For example, the control unit 11 of the server 10 may request the terminals 20B and 20C to transmit the location information of the terminals 20B and 20C as user information based on the call conditions transmitted from the terminal 20A.

When the control unit 21 of terminal 20B receives a request to send user information, it transmits the user information to the server 10 (C21). For example, the control unit 21 of terminal 20B may obtain its own location information using a positioning system such as GPS, and transmit the location information to the server 10 as user information. Similarly, when the control unit 21 of terminal 20C receives a request to send user information, it transmits the user information to the server 10 (D21).

When the control unit 11 of the server 10 receives user information from the terminals 20B and 20C of users B and C registered in the chat room R, the control unit 11 controls specific users among the multiple terminals 20A to 20C included in the chat room R who satisfy the call conditions and can participate in the call based on the user information (B91). Specifically, the control unit 11 of the server 10 extracts specific users whose user information satisfies the call conditions set in the terminal 20A, that is, specific users who exist within the range information 35, from among the users A to C included in the chat room R. Here, the control unit 11 of the server 10 extracts user B as a specific user who exists within the range information 35. In other words, user B exists within the range information 35, and user C exists outside the range information 35. When the control unit 11 of the server 10 extracts user B who satisfies the call conditions, the control unit 11 of the server 10 may control the terminal 20B so that the user B can participate in the call. For example, as shown in FIG. 9-5A, the control unit 11 of the server 10 may send participation information 75 for joining the call to the terminal 20B of user B who is available to join the call, among users A to C of the multiple terminals 20A to 20C. As a result, the control unit 21 of the terminal 20B sends a participation request to the server 10 requesting that the user B join the call with user A in response to the input operation of the join button 76 by user B (C93).

In this embodiment, terminals 20B and 20C are requested (B101) to transmit user information in response to a call request (A92) from terminal 20A, but the present invention is not limited to this as long as the user information of terminals 20B and 20C can be obtained. For example, the control unit 11 of the server 10 may request terminals 20B and 20C to transmit user information at a predetermined timing. This allows the control unit 11 of the server 10 to know in advance the user information of users B and C registered in chat room R. Then, when a call is requested from terminal 20A (B93), the control unit 11 of the server 10 controls specific users who can participate in the call by satisfying the call conditions among the multiple terminals 20A to 20C included in chat room R, based on the user information of terminals 20B and 20C obtained in advance (B91).

In this embodiment, the control unit 11 of the server 10 acquires the user information of the terminals 20B and 20C by requesting the terminals 20B and 20C to transmit the user information, but the present invention is not limited to this as long as the user information of the terminals 20B and 20C can be acquired. For example, the control unit 21 of the terminals 20B and 20C may automatically transmit their own user information to the server 10 (for example, transmit the user information at a predetermined interval). This allows the control unit 11 of the server 10 to always know the user information of the users B and C registered in the chat room R. Then, when the control unit 11 of the server 10 receives a call request from the terminal 20A (B93), the control unit 11 of the server 10 controls a specific user who satisfies the call conditions and can participate in the call from among the multiple terminals 20A to 20C included in the chat room R based on the user information of the terminals 20B and 20C acquired in advance (B91).

Effects of the Tenth Embodiment
In the tenth embodiment, the set call conditions include information related to the location.

As an example of the effect of such a configuration, user A of terminal 20A can easily set a specific user B as the call destination based on the location information.

In addition, in the tenth embodiment, the set call conditions include a condition that allows user B, who is located at a position specified by the user of terminal 20A, to participate in the call.

As an example of the effect of such a configuration, user A of terminal 20A can easily set a specific user B included in the location information as the call destination.

<Tenth Modification (1)>
In the tenth embodiment, the location information is searched and set by the designated location search unit 33a as shown in FIG. 1-8A, but the present invention is not limited to this as long as information related to the location can be set.

The tenth variant (1) is a variant in which the location information is set based on the location of user A of terminal 20A.

First, similarly to the tenth embodiment, the control unit 21 of the terminal 20A sets call conditions for extracting call destinations from among multiple users A to C registered in the chat room R (A92). Here, the call conditions may include location information that is set based on the location of user A.

The control unit 21 of the terminal 20A displays a location specification screen 33 on the display unit 24 as shown in FIG. 1-14A based on an input operation specifying user A's location information. At this time, the location information of user A is displayed on the location information display unit 33c of the location specification screen 33. The location information display unit 33c may display, for example, a map image including user A's location information. That is, the control unit 21 of the terminal 20A displays, on the display unit 24, a map image including user A's location information. Here, the location information may include specific location information 34 indicating the location of user A (for example, latitude and longitude information, information indicating a location, etc.). For example, the control unit 21 of the terminal 20A may obtain its own specific location information 34 using a positioning system such as GPS.

The control unit 21 of the terminal 20A may also set the specific position information 34 based on an input by the user A to the map image. For example, the control unit 21 of the terminal 20A may change the position of the specific position information 34 on the map image based on an input by the user A to the map image. This allows the user A to adjust the position of the specific position information 34. For example, the user A may change the position of the specific position information 34 to the position of stadium Ka.

The control unit 21 of the terminal 20A determines the location of the specific location information 34 in response to an input operation by the user A on the location determination button 33d. The location information may also include range information indicating a specific range. For example, when the location determination button 33d is operated, the control unit 21 of the terminal 20A may display range information 35 indicating a specific range on a map image, as shown in FIG. 1-14B.

In this way, the specific location information 34 and range information 35 are set by user A as location information of the target person of the call condition. In response to user A's input operation on the location designation button 33e, the control unit 21 of the terminal 20A may set the location information including the specific location information 34 and range information 35 as the call condition for extracting the target person to call. Then, when the call condition is set, the control unit 21 of the terminal 20A transmits a call request to the server 10 requesting that the call be processed based on the set call condition (A93).

<Effects of the Tenth Modification (1)>
In the tenth modified example (1), the call conditions include location information that is set based on the location of user A of terminal 20A.

As an example of the effect of this configuration, user A of terminal 20A can easily set call conditions based on his or her own location.

Eleventh Embodiment
In the tenth embodiment, the call conditions are composed of location information that specifies the location of the call destination, as shown in FIG. 1-8A, for example, but are not limited to this as long as they are conditions for extracting the call destination.

In the eleventh embodiment, the call conditions may include attribute information regarding the attributes of the user to be called, for example, attribute information set by the user in chat room R.

The same components as those in the first to tenth embodiments are designated by the same reference numerals and will not be described again. The contents described in the eleventh embodiment are also applicable to all of the other embodiments.

<Information Processing>
FIG. 11A is a flowchart showing an example of the flow of processes executed by each device in this embodiment.

First, as in the ninth embodiment, in response to an input operation by user A, a chat room R in which multiple users including user A to user C are registered is displayed on the display unit 24 (A91). Then, the control unit 21 of the terminal 20A accepts input of attribute information by user A (A111). Here, the attribute information is information on the attributes of each of users A to C, such as gender, age, hobbies, the date of registration of the chat room R, purchase history, search history, etc.

For example, as shown in FIG. 4-2A, the control unit 21 of the terminal 20A may display profile information 46 of the user A in response to an input operation by the user A, and may provide a setting button 47 for setting attribute information of the user A in the profile information 46. Here, the attribute information may be set as a tag for classifying the user A. When the setting button 47 is input by the user A, the control unit 21 of the terminal 20A may display a setting screen 48 including an input field 49 and a save button 50 as shown in FIG. 4-2B. Then, the control unit 21 of the terminal 20A accepts the input of attribute information by the user A in the input field 49. Here, it is assumed that the attribute information "#Fan of soccer team K", "#Fan for over 10 years", and "#Annual passport member" are input in the input field 49.

Next, the control unit 21 of the terminal 20A transmits the attribute information entered in the input field 49 to the server 10 in response to an input operation by user A on the save button 50 (A112). As a result, the attribute information of user A is set in the server 10. At this time, the attribute information may be set for chat room R, that is, set for each chat room R. As a result, attribute information specific to the chat room R is set.

Similarly, the control unit 21 of terminal 20B accepts input of attribute information by user B (C111) and transmits the attribute information of user B entered in input field 49 to the server 10 (C112). The control unit 21 of terminal 20C also accepts input of attribute information by user C (D111) and transmits the attribute information of user C entered in input field 49 to the server 10 (D112).

The attribute information is not limited to being set after users A to C are registered in chat room R. In other words, the attribute information may be set by users A to C before each of users A to C is registered in chat room R, which includes users B and C of multiple terminals 20B and 20C, and user A of terminal 20A. For example, the attribute information may be set by users A to C in the process of registering users A to C in chat room R (joining chat room R). Even in this case, the attribute information can be set in the same way as above, so a description will be omitted.

When the control unit 11 of the server 10 receives the attribute information of users A to C from terminals 20A to 20C, respectively, the control unit 11 stores the attribute information of users A to C in sequence in the storage unit 15 (B111). At this time, the control unit 11 of the server 10 may store the attribute information of each of users A to C as a tag for classifying users A to C. In this way, the attribute information is set by users A to C of each of the multiple terminals 20A to 20C.

Then, the control unit 21 of the terminal 20A sets call conditions for extracting call destinations from among the multiple users A to C registered in the chat room R based on the input operation of the user A (A92). Here, the call conditions may include attribute information of the users A to C. For example, the control unit 21 of the terminal 20A may display an attribute setting button 84 for setting attribute information as a call condition on the selection screen 72, as shown in FIG. 10-2.

For example, the control unit 21 of the terminal 20A requests the server 10 to transmit attribute information of users A to C registered in the chat room R in response to an input operation of the attribute setting button 84 by user A. Then, when the control unit 11 of the server 10 receives the request to transmit the attribute information from the terminal 20A, it refers to the storage unit 15 and transmits the attribute information of users A to C registered in the chat room R to the terminal 20A. For example, the control unit 11 of the server 10 may transmit tag information stored in the storage unit 15 as attribute information to the terminal 20A. Then, when the control unit 21 of the terminal 20A receives the attribute information from the server 10, it may display a list 51 of the attribute information on the display unit 24 as shown in FIG. 11-2. As a result, the control unit 21 of the terminal 20A accepts the selection of attribute information from user A in the list 51 of attribute information as shown in FIG. 11-3A.

Here, it is assumed that user A of terminal 20A has selected attribute information "#Annual Passport Member", for example. User A may or may not select multiple pieces of attribute information. When specific attribute information is selected, the control unit 21 of terminal 20A may display a call request button 74 in the attribute information list 51, as shown in FIG. 11-3B. Then, in response to user A's input operation on the call request button 74, the control unit 21 of terminal 20A sets the selected attribute information as a call condition, and transmits a call request to the server 10 requesting that the call be processed based on the call condition (A93).

When the control unit 11 of the server 10 receives a call request from the terminal 20A, it controls user B, who satisfies the call conditions and can participate in the call, among the multiple terminals 20A to 20C included in the chat room R based on the call conditions (B91). Specifically, the control unit 11 of the server 10 refers to the storage unit 15 and extracts specific users who satisfy the set call conditions, that is, specific users who register the attribute information "#annual pass member", from among the users A to C included in the chat room R. Here, the control unit 11 of the server 10 extracts user B as a specific user who registers the attribute information "#annual pass member". Then, when the control unit 11 of the server 10 extracts user B who satisfies the call conditions, it may transmit participation information 75 for participating in the call to the terminal 20B of user B who can participate in the call, among the users A to C of each of the multiple terminals 20A to 20C, as shown in FIG. 9-5A.

In this embodiment, the control unit 21 of the terminals 20A to 20C sets attribute information for each chat room R, for example, when registering the users A to C in the chat room R, but this is not limited as long as the attribute information of the users A to C can be set. For example, the control unit 21 of the terminals 20A to 20C may apply the preset attribute information of the users A to C to each chat room R. In other words, the control unit 21 of the terminals 20A to 20C may set the same attribute information to multiple chat rooms R.

Effects of the Eleventh Embodiment
In the eleventh embodiment, the set call conditions include attribute information related to user attributes.

As an example of the effect of such a configuration, user A of terminal 20A can easily set a specific user included in the attribute information as the call destination.

In the 11th embodiment, the attribute information is set by users B and C of the multiple terminals 20B and 20C, respectively.

As an example of the effect of such a configuration, user A of terminal 20A can appropriately set the call destination based on attribute information set by users B and C.

In the 11th embodiment, the attribute information is information that is set before registration in chat room R, which includes users B and C of terminals 20B and 20C, and user A of terminal 20A.

One example of the effect of this configuration is that users A to C of terminals 20A to 20C can reliably set attribute information.

In the 11th embodiment, the attribute information is information that is set for each chat room R.

As an example of the effect of this configuration, user A of terminal 20A is set with attribute information specific to chat room R, and can appropriately set the call destination based on that attribute information.

<Eleventh Modification (1)>
In the eleventh embodiment, the attribute information is set based on an input to the attribute setting button 84 as shown in FIG. 10B, but the present invention is not limited to this as long as the attribute information can be set.

In the eleventh variant (1), the attribute information is set based on the input of specific text information into the input area 31.

First, similarly to the eleventh embodiment, the control unit 21 of the terminal 20A sets call conditions for extracting call destinations from among the multiple users A to C registered in the chat room R, based on the input operation of the user A (A92). At this time, the control unit 21 of the terminal 20A may display on the display unit 24 a list 51 of attribute information of the users A to C registered in the chat room R, in response to the input of specific text information in the input area 31.

For example, as shown in FIG. 11-2, when a specific symbol, such as "#", which displays a list of attribute information 51, is entered in input area 31, control unit 21 of terminal 20A requests server 10 to transmit attribute information of users A to C registered in chat room R. Then, when control unit 11 of server 10 receives a request to transmit attribute information from terminal 20A, it refers to memory unit 15 and transmits the attribute information of users A to C registered in chat room R to terminal 20A.

As a result, the control unit 21 of the terminal 20A causes the display unit 24 to display a list 51 of attribute information of users A to C registered in the chat room R. When, for example, attribute information "#annual passport member" is selected by user A in the list 51 of attribute information, the control unit 21 of the terminal 20A may display a call request button 74 in the list 51 of attribute information as shown in FIG. 11-3B. Then, in response to user A's input operation on the call request button 74, the control unit 21 of the terminal 20A sets the selected attribute information as a call condition, and transmits a call request to the server 10 requesting that the call be processed based on the call condition (A93).

<Effects of the eleventh modified example (1)>
In the eleventh modified example (1), the attribute information is selected from a list 51 of attribute information of users A to C registered in the chat room R.

As an example of the effect of this configuration, user A of terminal 20A can easily set attribute information.

<Eleventh Modification (2)>
In the eleventh embodiment, the attribute information is set based on an input to the attribute setting button 84 as shown in FIG. 10B, but the present invention is not limited to this as long as the attribute information can be set.

In the eleventh variant example (2), the attribute information is selected from the profile information of users A to C included in chat room R.

First, similarly to the eleventh embodiment, the control unit 21 of the terminal 20A sets call conditions for extracting call destinations from among a plurality of users A to C registered in the chat room R, based on the input operation of the user A (A92). At this time, the control unit 21 of the terminal 20A may display profile information of the users A to C included in the chat room R on the display unit 24 in response to the input operation of the user A.

For example, as shown in FIG. 11-4, the control unit 21 of the terminal 20A may display profile information 46 including attribute information 85 of user A on the display unit 24. Next, when specific attribute information 85, for example "#annual passport member", is selected by user A from the displayed profile information 46 of user A, the control unit 21 of the terminal 20A may set the attribute information 85 as a call condition. Then, in response to an input operation by user A, the control unit 21 of the terminal 20A transmits a call request to the server 10 requesting that the call be processed based on the set call condition (A93).

<Effects of the eleventh modified example (2)>
In the eleventh modified example (2), the attribute information is selected from the profile information 46 of the users A to C included in the chat room R.

As an example of the effect of this configuration, user A of terminal 20A can easily set attribute information from profile information 46.

<Twelfth embodiment>
In the ninth to eleventh embodiments, the control unit 11 of the server 10 processes the call between the terminal 20A and the terminal 20B as shown in FIG. 9-6, but the users who can participate in the call may be changed during the call.

In the twelfth embodiment, the control unit 11 of the server 10 changes the users who can join the call based on input by user A of the terminal 20A during the call.

The same components as those in the first to eleventh embodiments are given the same reference numerals and will not be described again. The contents described in the twelfth embodiment can be applied to any of the other embodiments.

<Information Processing>
FIG. 12A is a flowchart showing an example of the flow of processes executed by each device in this embodiment.

First, as in the ninth embodiment, the control unit 11 of the server 10 processes a call between terminals 20A and 20B based on a participation request sent from terminal 20B, as shown in FIG. 9-6 (B92). Here, while the call is in progress, the control unit 11 of the server 10 may add users who can join the call based on input from a user registered in chat room R (e.g., a user with whom the call has been established). For example, the control unit 11 of the server 10 may add users who can join the call based on input from user A who has started the call.

For example, when user A of terminal 20A sets call conditions based on the location information shown in FIG. 1-8B in step B91 of the 10th embodiment, he/she may want to add a specific user who was not included in the location information to the call destination. Also, when user A of terminal 20A sets call conditions based on the attribute information shown in FIG. 11-2 in step B91 of the 11th embodiment, he/she may want to add a specific user who was not included in the attribute information to the call destination. Therefore, based on an input by user A, the control unit 21 of terminal 20A transmits a change request to the server 10 for the call conditions that change the users who can participate in the call (A121).

For example, when user A selects a specific user from among multiple users B and C registered in chat room R on the selection screen 72 shown in FIG. 9-4B, the control unit 21 of the terminal 20A may transmit to the server 10 a request to change the call conditions for adding the specific user to the call destination.

For example, when user A performs an input operation on the position specification screen 33 shown in FIG. 1-8B to expand the range information 35 of the location information, the control unit 21 of the terminal 20A may transmit to the server 10 a change request for the call conditions that change the range information 35 to the expanded range. For example, when user A performs an input operation on the selection screen 72 shown in FIG. 10-2 to add attribute information, the control unit 21 of the terminal 20A may transmit to the server 10 a change request for the call conditions that add the attribute information.

When the control unit 11 of the server 10 receives a call destination change request from the terminal 20A, it controls to add users who can participate in the call based on the call conditions changed by the user A of the terminal 20A (B121). That is, the control unit 11 of the server 10 controls to change the users who can participate in the call based on the input by the user A of the terminal 20A while the call is in progress. At this time, the control unit 11 of the server 10 may change the users who can participate in the call based on the input by the user A of the terminal 20A that changes the location information or attribute information as described above.

Specifically, the control unit 11 of the server 10 extracts the specific user that has been added under the changed call conditions. Here, it is assumed that the control unit 11 of the server 10 extracts user C as the specific user that has been added. When the control unit 11 of the server 10 extracts the specific user C that has been added, the control unit 11 of the server 10 may control the terminal 20C so that the user C can participate in the call. For example, the control unit 11 of the server 10 transmits participation information 75 for participating in the call to the terminal 20C of user C who has been added as a user who can participate in the call.

As a result, the control unit 21 of the terminal 20C displays the participation information 75 shown in FIG. 9-5A in the chat room R (D121). Then, when the user C inputs the join button 76, the control unit 21 of the terminal 20C sends a join request to the server 10 requesting that the user C join the call with users A and B (C122).

When the control unit 11 of the server 10 receives the participation request from the terminal 20C, it adds the terminal 20C to the call processing of the terminals 20A and 20B based on the participation request, and processes the call by the terminals 20A to 20C (B122). As a result, the control unit 11 of the server 10 establishes a call connection between the terminals 20A to 20C, and the user A can make a call with the users B and C who satisfy the call conditions.

Effects of the twelfth embodiment
In the twelfth embodiment, the control unit 11 of the server 10 changes users who can participate in a call based on an input by the user A of the terminal 20A while the call is in progress.

As an example of the effect of such a configuration, user A of terminal 20A can easily change users who can participate in a call.
For example, if a specific user is not included among the users who can participate in a call extracted based on location information or attribute information, user A of terminal 20A can easily add the specific user as a user who can participate in the call.

In addition, in the 12th embodiment, the control unit 11 of the server 10 changes the users who can participate in the call based on the input of location information or attribute information by user A of the terminal 20A.

As an example of the effect of such a configuration, user A of terminal 20A can change users who can join a call at once based on location information or attribute information.

<Twelfth Modification (1)>
In the twelfth embodiment, the control unit 11 of the server 10 adds the user C who can participate in the call between the users A and B, but the present invention is not limited to this as long as it is possible to change the users who can participate in the call.

In the twelfth variant example (1), the control unit 11 of the server 10 may reduce the number of users who can participate in the call based on input by user A of the terminal 20A.

First, as in the twelfth embodiment, the control unit 11 of the server 10 processes a call between the terminal 20A and another terminal 20 (B92). Note that the control unit 11 of the server 10 processes calls between the terminals 20A to 20C based on participation requests sent from the terminals 20B and 20C, as shown in FIG. 12-2.

Here, while the call is in progress, the control unit 11 of the server 10 may reduce the number of users who can join the call based on an input by the user with whom the call has been established. For example, the control unit 11 of the server 10 may reduce the number of users who can join the call based on an input by user A who has started the call.

For example, when user A of terminal 20A sets call conditions based on the location information shown in FIG. 1-8B in step B91 of the tenth embodiment, he/she may want to remove a specific user from the call destinations that satisfy the location information. Also, when user A of terminal 20A sets call conditions based on the attribute information shown in FIG. 11-2 in step B91 of the eleventh embodiment, he/she may want to remove a specific user from the call destinations that satisfy the attribute information. Therefore, the control unit 21 of terminal 20A transmits a change request to the server 10 based on the call conditions that have changed the users who can participate in the call in response to input by user A (A121).

For example, the control unit 21 of the terminal 20A may transmit a change request to the server 10 based on the call conditions that remove a specific user from the call destinations when the specific user is selected by the user A from among the multiple users B and C selected as call destinations on the selection screen 72 shown in FIG. 9-4B.

For example, when user A inputs an operation to reduce the range information 35 of the location information on the position specification screen 33 shown in FIG. 1-8B, the control unit 21 of the terminal 20A may transmit a change request to the server 10 based on the call conditions in which the range information 35 has been changed to the reduced range. For example, when user A inputs an operation to reduce attribute information on the selection screen 72 shown in FIG. 10-2, the control unit 21 of the terminal 20A may transmit a change request to the server 10 based on the call conditions in which the attribute information has been reduced.

When the control unit 11 of the server 10 receives a call destination change request from the terminal 20A, the control unit 11 controls to reduce the number of users who can participate in the call based on the call conditions changed by the user A of the terminal 20A (B121). That is, the control unit 11 of the server 10 controls to change the users who can participate in the call based on the input by the user A of the terminal 20A while the call is in progress. At this time, the control unit 11 of the server 10 may change the users who can participate in the call based on the input by the user A of the terminal 20A that changes the location information or attribute information as described above.

Specifically, the control unit 11 of the server 10 extracts the specific users that have been removed under the changed call conditions. Here, it is assumed that the control unit 11 of the server 10 extracts user C as a specific user that has been removed. When the control unit 11 of the server 10 extracts the specific user C that has been removed, the control unit 11 of the server 10 may control the terminal 20C so that the user C cannot participate in the call. For example, the control unit 11 of the server 10 may disconnect the call connection of the terminal 20C in the call processing of the terminals 20A to 20C. As a result, the control unit 11 of the server 10 processes the call between the terminals 20A and 20B, as shown in FIG. 9-6, and the call is switched to the call between the users A and B.

<Effects of the twelfth modified example (1)>
In the twelfth modified example (1), the control unit 11 of the server 10 reduces the number of users who can participate in the call based on an input by the user A of the terminal 20A while the call is in progress.

As an example of the effect of this configuration, user A of terminal 20A can easily adjust the users who can join the call.

Thirteenth Embodiment
In the ninth to twelfth embodiments, the participation information 75 shown in FIG. 9-5A controls the terminal 20B to be able to participate in the call with the user A, but may include other information.

In the thirteenth embodiment, the participation information 75 includes user information about user B, who is able to participate in the call, among users A to C included in chat room R.

The same components as those in the first to twelfth embodiments are designated by the same reference numerals and will not be described again. The contents described in the thirteenth embodiment are also applicable to any of the other embodiments.

First, as in the eleventh embodiment, the control unit 11 of the server 10 transmits participation information 75 to the terminal 20B based on the call conditions set by the user A, and controls so that the user B can participate in the call (B91). Here, it is assumed that the users A to D are registered in the chat room R, and the control unit 11 of the server 10 extracts the users B and D as specific users who can participate in the call based on the call conditions. The control unit 11 of the server 10 may transmit participation information 75 including user information on the users B and D who can participate in the call, among the users A to D included in the chat room R, to the terminals 20B and 20D. Examples of the user information include attribute information.

As shown in FIG. 13-1, when the control unit 21 of the terminal 20B receives the participation information 75 including the attribute information 86, it displays the participation information 75 in the chat room R (C92). The participation information 75 may display the attribute information 86 of all users B and D who can participate in the call. Here, it is assumed that the attribute information 86 displayed is "#Fan of soccer team K", "#Fan for over 10 years", and "#Annual passport member".

The control unit 21 of terminal 20B may then set the specific attribute information 86 as a tag for user B based on an input operation by user B to user D's attribute information 86 indicating, for example, "#Fan of soccer team K." For example, the control unit 21 of terminal 20B transmits the specific attribute information 86 to the server 10 so as to set it as user B's tag. When the control unit 11 of the server 10 receives the specific attribute information 86 from terminal 20B, it stores the specific attribute information 86 in the storage unit 15 as user B's tag. As a result, the attribute information 86 of user D is set as the attribute information 86 of user B.

Furthermore, similar to the 11th embodiment, the control unit 21 of the terminal 20B transmits a join request to the server 10 requesting that the user B join the call with the user A in response to an input operation of the join button 76 by the user B (C93).

In addition, the control unit 11 of the server 10 may transmit display information 75a indicating the display contents of the participation information 75 to the terminal 20C of user C, who is unable to participate in the call, among users A to D included in chat room R, as in the eleventh embodiment. In this case, the display information 75a may include user information of users B and D who are able to participate in the call, among users A to D included in chat room R. For example, as shown in FIG. 13-2, the display information 75a may display attribute information 86 of all users B and D who are able to participate in the call.

When specific attribute information 86 indicating, for example, "#Fan of soccer team K" is input by user C, the control unit 21 of terminal 20C may set the specific attribute information 86 as a tag for user C. For example, the control unit 21 of terminal 20C transmits the specific attribute information 86 to the server 10 so as to set it as a tag for user C. When the control unit 11 of the server 10 receives the specific attribute information 86 from terminal 20C, it stores the specific attribute information 86 in the storage unit 15 as a tag for user C. As a result, the attribute information 86 of user D who can participate in the call is set as the attribute information 86 of user C who cannot participate in the call. Then, when the attribute information 86 of user D who can participate in the call is set as the attribute information of user C who cannot participate in the call, the control unit 11 of the server 10 allows user C to participate in the call and processes the call of terminals 20A to 20D. That is, the control unit 11 of the server 10 establishes a call connection between terminals 20A, 20B, and 20D and terminal 20C, and user A can talk to users B to D who can join the call.

Effects of the Thirteenth Embodiment
In the thirteenth embodiment, participation information 75 includes user information (not limited to this, but an example of information about users) about users B and D who are able to participate in the call, among users A to D included in chat room R.

As an example of the effect of such a configuration, the control unit 21 of the terminal 20B can easily set the attribute information of another user D as the user information, for example, attribute information, of the user B.

In addition, in the 13th embodiment, the control unit 11 of the server 10 transmits display information 75a including user information of users B and D who can participate in the call to the terminal 20C of user C, who is unable to participate in the call, among users A to D included in the chat room R.

As an example of the effect of such a configuration, user C of terminal 20C can easily set attribute information of users B and D who can participate in the call as his/her own attribute information.
Furthermore, user C of terminal 20C can easily participate in a call between users A, B, and D by setting attribute information of users B and D who can participate in the call as his/her own attribute information.

<Fourteenth embodiment>
In the ninth to thirteenth embodiments, the call conditions are set, for example, by selecting a specific user on the selection screen 72 shown in FIG. 9-4B, but the present invention is not limited to this as long as a specific user who can participate in the call can be selected.

In the fourteenth embodiment, the call conditions include input information regarding user A's input to the first content displayed in chat room R.

First, the control unit 21 of the terminal 20A displays a chat room R on the display unit 24 as shown in FIG. 9-4A, and sets call conditions for extracting call destinations from among the multiple users A to C registered in the chat room R based on an input operation by the user A (A92). Here, when a first content M is selected by the user A from the multiple contents displayed in the chat room R, for example the first content M sent by the user B, the control unit 21 of the terminal 20A may set input information related to the input to the first content M as the call conditions. That is, the call conditions include input conditions related to the input to the first content M included in the chat room R. Here, examples of the input conditions include information associated with the first content M.

For example, the call conditions may be set based on sender information (e.g., identification information, etc.) related to the sender included in the first content M. Specifically, when the first content M1 is selected by the user A, the control unit 21 of the terminal 20A acquires sender information stored in association with the first content M1 from the storage unit 28 or the server 10. Then, the control unit 21 of the terminal 20B may set call conditions that specify the user B who is the sender of the first content M based on the acquired sender information. Note that, when multiple first contents M are selected by the user A, the control unit 21 of the terminal 20A may set call conditions that specify multiple users who sent the multiple first contents M. When the call conditions are set, the control unit 21 of the terminal 20A transmits a call request to the server 10 requesting that the call be processed based on the call conditions (A93).

As a result, as shown in FIG. 9-5A, the control unit 11 of the server 10 controls the terminals 20A-20C included in the chat room R based on the call conditions set on the terminal 20A so that user B who satisfies the call conditions can participate in the call, for example by sending participation information for participating in the call to terminal 20B (B91).

Effects of the Fourteenth Embodiment
In the fourteenth embodiment, the set call conditions include an input condition regarding an input to the first content M included in the chat room R (this is not a limitation, but is an example of a condition regarding an input).

As an example of the effect of this configuration, user A of terminal 20A can easily set call conditions by simply selecting the first content M.

In addition, in the 14th embodiment, the set call conditions are based on sender information about the sender included in the first content M (not limited to this, but an example of information about the sender).

As an example of the effect of this configuration, user A of terminal 20A can easily specify the sender of first content M as the intended call recipient.

<Fourteenth Modification (1)>
In the fourteenth embodiment, the control unit 21 of the terminal 20A sets call conditions that specify only user B in response to user A's input operation for the first content M, but this is not limited to the above as long as the call conditions can be set.

In the 14th variant (1), when multiple users are associated with the first content M, the control unit 21 of the terminal 20A may set a call condition that specifies a specific user from among the multiple users based on an input operation of the user A for the first content M.

First, as in the fourteenth embodiment, the control unit 21 of the terminal 20A sets call conditions for extracting call destinations from among the multiple users A to C registered in the chat room R based on the input operation of the user A (A92). Here, as shown in FIG. 14-1, when the first content M includes the second content Ma and the third content Mb, the control unit 21 of the terminal 20A may set call conditions for specifying a specific user from among the multiple users associated with the first content M based on the input operation of the user A for the first content M. Here, the first content M includes the second content Ma transmitted from the user B and the third content Mb transmitted from the user D. This first content M may be formed, for example, by the user D using the reply function to reply to the second content Ma after the second content Ma is transmitted from the user B.

The reply function may refer to a function of replying to a specific second content Ma. For example, user D of terminal 20D selects a specific second content Ma sent from user B's terminal 20B, and replies to the second content Ma with a third content Mb using the reply function. In such a case, the third content Mb may be displayed in association with the second content Ma, for example, displayed integrally with the second content Ma. As a result, the first content M is displayed on the display unit 24 of terminal 20B so as to include the second content Ma and the third content Mb.

Here, the control unit 21 of the terminal 20A may set a call condition that specifies user B associated with the second content Ma when user A inputs a portion of the first content M that corresponds to the second content Ma. Also, the control unit 21 of the terminal 20A may set a call condition that specifies user D associated with the third content Mb when user A inputs a portion of the first content M that corresponds to the third content Mb. Also, the control unit 21 of the terminal 20A may set a call condition that specifies all users B and D associated with the first content M, i.e., user B associated with the second content Ma and user D associated with the third content Mb, in response to user A's input operation on the first content M.

When the call conditions are set, the control unit 21 of terminal 20A sends a call request to the server 10 requesting that the call be processed based on the call conditions (A93). As a result, as shown in FIG. 9-5A, the control unit 11 of the server 10 controls the call so that, based on the call conditions set in terminal 20A, among the multiple terminals 20A-20D included in chat room R, users B or D who satisfy the call conditions can participate in the call, for example by sending participation information for participating in the call to terminal 20B or 20D (B91).

<Effects of the fourteenth modified example (1)>
In the 14th variant example (1), when multiple users are associated with a first content M, the control unit 21 of the terminal 20A sets call conditions to specify a specific user from multiple users B and D based on an input operation of user A for the first content M.

As an example of the effect of such a configuration, user A of terminal 20A can easily select a specific user from among multiple users B and D associated with the first content M.

<Fifteenth embodiment>
In the ninth to fourteenth embodiments, the control unit 11 of the server 10 controls the specific user to be able to participate in the call based on the call conditions (B91), but this is not limited to the above as long as the specific user can be allowed to participate in the call.

In the fifteenth embodiment, the control units 21 of the terminals 20B and 20C determine whether or not users B and C satisfy the call conditions based on the call conditions set in the terminal 20A.

The same components as those in the first to fourteenth embodiments are designated by the same reference numerals and will not be described again. The contents described in the fifteenth embodiment are also applicable to any of the other embodiments.

<Functional configuration>
15A is a diagram showing an example of information stored in the storage unit 28 of the terminal 20 in this embodiment. The storage unit 28 stores, by way of example and not limitation, a terminal main processing program 281 that is read out by the control unit 21 and executed as the terminal main processing.

The terminal main processing program 281 also includes, as a subroutine program, a joining user control processing program 2811, which is read by the control unit 21 and executed as joining user control processing, but is not limited to this example.

The terminal main processing program 281 also includes, as a subroutine program, a participation request processing program 2812, which is read by the control unit 21 and executed as a participation request process, but is not limited to this example.

FIG. 15-2 is a diagram showing an example of functions realized by the control unit 21 of the terminal 20 in this embodiment. The control unit 21 has, by way of example and not limitation, a terminal main processing unit 211, a joining user control processing unit 212, and a joining request processing unit 213.

The terminal main processing unit 211 has the function of executing terminal main processing, which is processing for comprehensively controlling the terminal 20, in accordance with the terminal main processing program 281 stored in the memory unit 28.

The participating user control processing unit 212 controls whether users can join a call based on the set call conditions in accordance with the participating user control processing program 2811 stored in the memory unit 28.

The participation request processing unit 213 transmits a participation request to the server 10 to request participation in a call with user A based on control that enables participation in the call in accordance with the participation request processing program 2812 stored in the memory unit 28.

<Information Processing>
FIG. 15C is a flowchart showing an example of the flow of processing executed by each device in this embodiment.

First, as in the ninth embodiment, when the control unit 21 of the terminal 20A sets the call conditions, it transmits a call request to the server 10 requesting that the call be processed based on the set call conditions in response to an input operation by user A (A93). When the control unit 11 of the server 10 receives the call request from the terminal 20A, it transmits the call conditions included in the call request to the terminals 20B and 20C of users B and C registered in the chat room R (B151). Here, it is assumed that user B satisfies the call conditions, and user C does not satisfy the call conditions.

When the control unit 21 of the terminal 20B receives the call conditions from the server 10, the control unit 21 determines whether or not the user B satisfies the call conditions (C151). For example, if the user B is selected as the call destination on the selection screen 72 shown in FIG. 9-4B, the control unit 21 of the terminal 20B determines that the user B satisfies the call conditions.

Also, as shown in the tenth embodiment, when the call conditions include location information, the control unit 21 of the terminal 20B may acquire its own location information using a positioning system such as GPS, and determine whether its own location information satisfies the location information of the call conditions. For example, the control unit 21 of the terminal 20B may determine that the user B satisfies the call conditions when its own location information is included within the range of the range information 35 shown in FIG. 1-8B.

When the control unit 21 of the terminal 20B determines that the user B satisfies the call conditions, the control unit 21 controls each unit of the terminal 20B so that the user B can participate in the call with the user A (C152). For example, the control unit 21 of the terminal 20B displays participation information 75 for participating in the call in the chat room R, as shown in FIG. 9-5A.

Similarly, when the control unit 21 of terminal 20C receives the call conditions from the server 10, it determines whether or not user C satisfies the call conditions (D151). For example, the control unit 21 of terminal 20C determines that user C satisfies the call conditions when user C is not selected as the call destination on the selection screen 72 shown in FIG. 9-4B. Furthermore, the control unit 21 of terminal 20C may determine that user C does not satisfy the call conditions when the user's own location information is not included within the range information 35 shown in FIG. 1-8B. Then, when the control unit 21 of terminal 20C determines that user C does not satisfy the call conditions, it does not display participation information 75 for joining the call in chat room R, as shown in FIG. 9-5B.

Then, the control unit 21 of terminal 20B sends a participation request to the server 10 requesting participation in the call with user A based on user B's input operation on the participation information 75 displayed in chat room R (C93). As a result, the control unit 11 of the server 10 processes the call between terminal 20A and terminal 20B (B92), as shown in FIG. 9-6.

<Effects of the fifteenth embodiment>
In the fifteenth embodiment, the control units 21 of the terminals 20B and 20C determine whether or not the users B and C satisfy the call conditions based on the set call conditions. Then, when the control units 21 of the terminals 20B and 20C determine that the users B and C satisfy the call conditions, they control the terminals 20B and 20C to allow the users B and C to participate in the call with the user A.

As an example of the effect of such a configuration, user A of terminal 20A can talk to a specific user B among users B and C registered in chat room R.
