Description

  The present invention relates to a technique for solving a problem in transmitting and receiving messages between users at a site such as SNS (Social Networking Service).

  In recent years, services that allow browsing, sharing, and exchange of various messages by sites using the Internet have become widespread (see, for example, Patent Document 1).

JP 2008-242893 A

By the way, in providing such services, there is a social demand for appropriate protection of young people.
The present invention has been made in view of the above-described circumstances, and one of the purposes thereof is a system in which a message is transmitted from a user to only one stranger in a system for transmitting and receiving messages between users. It is to provide a function for avoiding this.

  Means employed by the present invention to achieve the above object will be described. In order to facilitate the understanding of the present invention, reference numerals in the drawings are appended in parentheses for convenience in the following, but the present invention is not intended to be limited to the illustrated forms.

  In order to achieve the above object, a control device (10) according to the present invention is a control device (10) applied to a system that transmits and receives messages between users, and is a candidate for a message destination. A receiving unit (125) for receiving a search condition for user attribute information from a requesting user requesting presentation of the user, and a specifying unit (126 for specifying a candidate user who satisfies the search condition received by the receiving unit. ) And a display control unit (123) that displays the candidate users specified by the specifying unit (126) on the display unit (211) in a selectable manner, the display control unit (123) Before the user other than the specific user indicated by the age information among the candidate users specified in the section (126) is selected, the requesting user selects the specific user. There is displayed as is prohibited, after which the user is selected, and wherein the displaying such that the required use selection of the specific user by the user is permitted.

According to the present invention, selection of the juvenile is prohibited until the requesting user selects a user other than the juvenile when selecting the candidate user. For this reason, it becomes possible not to transmit a message only to one young person from a demanding user.
In addition, the message here refers to information that identifies the sender and the transmission date and time of the message, in addition to text information such as text, audio information, video information, and the like that are made available to the user. Information and incidental information such as information defining the behavior of the avatar representing the sender. In addition, a message using only incidental information may be transmitted and received without main body information.
User attribute information is information related to other than the user's age, such as name (regardless of real name or nickname), residence, and sex. The juvenile is determined based on the age information stored in the storage unit, for example, a person younger than 18 years.
In the display control unit, the display is performed so that selection is prohibited or permitted. The control of the display unit is not only a case of directly controlling the display contents of the display unit, but also a program describing the display control. This includes a case where the screen information in which the information is embedded is transmitted to the terminal device including the display unit, while the display content is indirectly controlled according to the program.

  In the present invention, the specifying unit (108) accesses the storage unit (106) that stores the attribute information and the age information in association with each other for each of a plurality of users, and specifies the age information of the identified candidate users. The structure which acquires is preferable. In this configuration, “store attribute information and age information in association with each other” includes an aspect in which age information is directly associated with attribute information and stored, and age information is indirectly associated with attribute information through an ID or the like. In other words, it may be stored in such a manner that the age information of the user indicated by the attribute information can be acquired.

  The above object can also be achieved by the control device (10) having the following configuration. That is, a control device (10) applied to a system for transmitting / receiving a message between users, from a requesting user who requests presentation of a candidate user who is a candidate for a message transmission destination, user attribute information The receiving unit (125) that receives the search condition and the storage unit (106) that stores the attribute information and the age information in association with each other for each of the plurality of users are accessed and received by the receiving unit (125). And a display control unit (123) for selecting a candidate user specified by the specifying unit and a display control unit (123) for selectively displaying the candidate user specified by the specifying unit on the display unit. The control unit (123) is configured so that the specific user by the requesting user is selected before a user other than the specific user indicated by the age information is selected. By the control device (10), which is displayed so that the selection is prohibited, and after the user is selected, the requesting user is allowed to select the specific user. Can also be achieved. This control device (10) also prohibits the selection of juveniles until the requesting user selects a user other than the juvenile when selecting a candidate user. It becomes possible to make it impossible to send a message only to young people. In this configuration, “store attribute information and age information in association with each other” includes an aspect in which age information is directly associated with attribute information and stored, and age information is indirectly associated with attribute information through an ID or the like. In other words, it may be stored in such a manner that the age information of the user indicated by the attribute information can be acquired.

In the present invention, the storage unit (106) stores member information indicating whether the user is a regular member or an associate member for each of a plurality of users, and the display control unit (123) stores the specific usage. It is preferable that a display is made so that selection of the specific user is permitted or prohibited, including the associate member. In addition, when it is a user whose age information is unknown and it cannot be determined whether or not the user is a young person, the user may be included in the specific user.
According to this configuration, the requesting user can be prevented from specifying whether the specific user whose selection is prohibited is a juvenile or an associate member. Here, the associate member refers to a person whose restrictions are imposed on the type, scope, authority, etc. of the service provided compared with the regular member. In other words, it is only necessary to provide a grading that provides different services to the members. The member with the higher grading is the regular member, and the member with the lower grading is the associate member.

In this invention, the said memory | storage part (106) is linked | related with the identification information which identifies a user uniquely about the friend relationship between users, The said display control part (123) is the said specific user. When the request user is in a friendship relationship, the request user may be displayed so that the specific user can be selected. This is because there is no reason to prohibit the requesting user from sending a message to only one young person when the requesting user and the young person are in a friendship or acquaintance relationship in the real world. An example of an acquaintance relationship between a demanding user and a young person in the real world is parent and child.
In addition, the case where a specific user and a request | requirement user are friend relations is a case where it mutually sets as a friend in the said SNS. Here, being set to each other means that the friendship is recognized with each other. Once a friendship has been established, it is optional whether or not the requesting user is allowed to select a specific user for a user whose friendship has been canceled by setting from one side. . In addition, in the case of an SNS that can establish a one-sided friendship, the requesting user is allowed to select a specific user when the younger side is a one-sided friendship for the requesting user. It is good also as a structure displayed on. Moreover, even if it is not a friend relationship in the SNS, a user in which a predetermined relationship is established in an application such as image sharing or a game provided in the SNS may be included in the friend relationship in the SNS. good.

  In this invention, it is good also as a structure provided with the management part (127) which manages so that a message can be transmitted to the one or some user selected by the said request | requirement user among the said candidate users.

In the present invention, the system (1) transmits and receives messages between two or more users constituting a group, and the reception unit (125) withdraws from the group in which the users are participating. The management unit (127) receives a request, and when the user received by the reception unit (125) is deleted from the group, when the number of users participating in the group becomes one, the group A configuration that makes it impossible to use is preferable. According to this configuration, when one user joins the group due to withdrawal from a certain user, the group is prevented from being left behind.
Making the use of a group impossible means that a new message cannot be transmitted / received in the group, and messages sent and received so far may be kept in a viewable state. Further, the group may be reused by adding a new user. In other words, it means that the user cannot use the service when the user who has joined the group becomes one due to the withdrawal of a certain user.

  In this configuration, when the management unit (127) deletes the user received by the reception unit (125) from the group in which the user is participating, two users participating in the group are included. A mode in which when the user is a specific user and one of them is a specific user, the use of the group is not preferable. According to this aspect, even when the number of people who have joined the group afterwards is two, and one of them is a specific user of a young person (or associate member), the use of the group Therefore, it is possible to prevent a user from sending a message to only one young person. Making the use of a group impossible means that a new message cannot be transmitted in the group, and messages sent and received so far may be viewable. Further, the group may be reused by adding a new user. In other words, when the number of people who have joined the group afterwards is two, one of them is a specific user, meaning that it cannot be used.

  Here, the management unit (127) may cause the user to join the group when the user selected by the requesting user agrees. This prevents a certain user from participating in a certain group without knowing it.

The above object can also be achieved by the control device (10) having the following configuration. That is, a control device (10) applied to a system for transmitting / receiving a message between users, from a requesting user who requests presentation of a candidate user who is a candidate for a message transmission destination, user attribute information A receiving unit (125) that receives the search conditions, a specifying unit (126) that specifies candidate users that satisfy the search conditions received by the receiving unit, and a candidate user specified by the specifying unit (126). A display control unit (123) that is displayed on the display unit in a selectable manner, and the display control unit (123) is a young person based on age information among candidate users specified by the specifying unit (126). When a user other than the specific user indicated is selected, an error is output to the display unit (211), and the specific is performed by the requesting user after the user is selected. It can be achieved by the control device (10), characterized in that not an error on the display unit if the use individual is selected.
Moreover, the said objective can be achieved also by the control apparatus (10) of the following structures. That is, a control device (10) applied to a system for transmitting / receiving a message between users, from a requesting user who requests presentation of a candidate user who is a candidate for a message transmission destination, user attribute information The receiving unit (125) that receives the search condition and the storage unit (106) that stores the attribute information and the age information in association with each other for each of the plurality of users are accessed and received by the receiving unit (125). A specifying unit (126) for specifying candidate users that satisfy the search conditions, and a display control unit (123) for displaying the candidate users specified by the specifying unit (126) on the display unit (211) so as to be selectable. The display control unit (123) includes the requesting user before the user other than the specific user indicated by the age information is selected. When the specific user is selected, an error is output to the display unit (211), and the display unit is selected when the specific user is selected by the requesting user after the user is selected. This can also be achieved by the control device (10) characterized in that no error is output in (211).
Such a control device (10) includes a management unit (127) that manages a message to be transmitted to one or a plurality of users selected by the requesting user from among the candidate users. The management unit (127) may make the use of the group impossible when the request user and the specific user constitute a group.

The present invention can be conceptualized not only as a control device (10) as a server, but also as a control method of the control device (10) and a program that causes a computer to function as the server (10). It can also be conceptualized as a program that causes a computer that can communicate with the server (10) to function as a terminal device (20) operated by a user.
Here, the program that causes the computer to function as the server (10) may be recorded on a recording medium. If this recording medium is used, the program can be installed in the computer, for example. Here, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM.
Further, a program that causes a computer to function as the terminal device (20) may also be recorded on a recording medium. The program that causes the computer to function as the terminal device (20) includes an internal or external recording medium that can be accessed from the distribution server in order to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program that can be executed by the terminal device (20). That is, the format stored in the distribution server does not matter as long as it can be downloaded from the distribution server and installed in a form that can be executed by the terminal device (20). The program may be divided into a plurality of parts, downloaded at different timings, and combined in the terminal device (20), or the distribution server that distributes each of the divided programs may be different.

  Embodiments of the present invention will be described below with reference to the drawings.

<Overall configuration>
FIG. 1 is a block diagram illustrating an overall configuration of a system to which a control device according to an embodiment is applied.
As shown in this figure, in the system 1, a plurality of terminal devices 20-1, 20-2, 20-3,... Function as control devices via the mobile communication network Nb, the gateway 15, and the Internet Na. The configuration is connected to the SNS server 10.
In the following, since the terminal devices 20-1, 20-2, 20-3,... Are generally described without specifying the terminal devices, “-(hyphen)” and the following in the reference numerals are simply omitted. “20”.

The SNS server 10 is operated by an SNS operator and provides a social networking service for SNS members (hereinafter simply referred to as “members”) to interact with each other. This service includes providing various games to members, and providing a service for sending and browsing messages among a plurality of users constituting a group.
In order to provide such various services, the SNS server 10 manages information on members, messages transmitted from the members, and the like. In addition, the SNS server 10 stores information necessary for creating a group and browsing a message, which will be described later, in a table.

  FIG. 2 is a block diagram illustrating a hardware configuration of the SNS server 10. As shown in this figure, the SNS server 10 stores a CPU (Central Processing Unit) 101 that controls the entire apparatus, a RAM (Random Access Memory) 102 that functions as a main storage unit of the CPU 101, a boot program, and the like. A ROM (Read Only Memory) 103, an interface (I / F) 105 for communicating via a network, and a storage unit 106 of a storage unit for storing various programs and data are included. The storage unit 106 stores a database 108 and is managed by the CPU 101.

Details of data and tables managed by the database 108 will be described later. In addition, the SNS server 10 is provided with a real-time clock that outputs time information, but the illustration is omitted.
In addition, although the SNS server 10 is constructed as a single unit in FIG. 1, it may be configured so that it is distributed to two or more units and virtually viewed as one unit when viewed from the outside. On the other hand, some functions of the SNS server 10 may be constructed by a server that provides other services. Moreover, you may comprise so that the SNS server 10 may connect with the terminal device 20 via a relay server.

  The terminal device 20 is a mobile phone operated by a user, for example. The terminal device 20 includes a touch panel 212 overlaid on the display unit 211, and allows a user to input necessary information and various instructions by touching the screen of the display unit 211. It has become.

  FIG. 3 is a block diagram illustrating a hardware configuration of the terminal device 20. As shown in this figure, the terminal device 20 includes a CPU 201, a RAM 202, a ROM 203, a communication unit 204, a storage unit 205, an RTC (Real Time Clock) 206, a display unit 211, a touch panel 212, including.

Among these, the CPU 201 controls the entire terminal device 20, the RAM 202 is used as a main storage unit of the CPU 201, and the ROM 203 stores a basic program and the like. The communication unit 204 communicates with the SNS server 10 via the mobile communication network Nb.
The storage unit 205 stores application programs for receiving provision of various services from the SNS server 10, various data, and the like. The application program here is provided by the SNS operator, downloaded from a specific distribution server, and installed in the terminal device 20. The terminal device 20 is installed with a browser for browsing a web page describing display control. The RTC 206 outputs time information of the current time.

The display unit 211 is a display panel such as a liquid crystal display device or an organic EL (Electro Luminescence) device. Although not described in detail, the touch panel 212 detects a touch position (XY coordinate value) on the display screen by the display unit 211 and outputs position information indicating the detected touch position to the CPU 201. Based on the position information from the touch panel 212, the CPU 201 detects the moving direction of the touch position, the moving speed, the type of touch operation, and the like.
Here, the types of touch operations that can be detected include, for example, tap, flick, drag, pinch and the like. Of these, tapping is an operation of tapping the display screen with a finger. Flicking is an operation in which the object displayed on the screen is gently touched with a finger. Dragging is an operation of moving an object displayed on the screen in contact with a finger. Pinch is an operation of expanding or narrowing a display screen with two fingers in contact with each other.

  The terminal device 20 is not limited to the mobile communication network Nb, and may be configured to be connected to a wireless LAN (Local Area Network). When connected to a wireless LAN, the terminal device 20 is connected to the SNS server 10 via a wireless base station (access point) and the Internet Na. The terminal device 20 is not limited to a mobile phone, and may be a tablet computer or a PDA (Personal Digital Assistant).

FIG. 4 is a diagram showing functional blocks constructed in the system 1 when the terminal device 20 receives service provision from the SNS server 10 by a message function (messenger). As shown in this figure, on the SNS server 10 side, a display control unit 123, a reception unit 125, a specifying unit 126, and a management unit 127 are constructed by the CPU 101 executing a program for providing a service.
The database 108 also includes a user registration table TB1 for storing member information, a group registration table TB2 for storing information about groups, a friend relationship storage table TB3 for storing friendships among members, and a post / response. A posting / response history storage unit 118 that stores the history for each group is managed.
Details of the user registration table TB1, the group registration table TB2, the friend relationship storage table TB3, and the posting / response history storage unit 118 will be described later.

On the other hand, on the terminal device 20 side, the browser 221 and the operation detection unit 222 are constructed by the CPU 201 executing the application program.
The operation detection unit 222 outputs the operated position and type based on the position information detected by the touch panel 212.
The browser 221 analyzes the web screen information transmitted from the SNS server 10 and causes the display unit 211 to display the web screen information. Controls such as switching, moving, and giving movement to the display are performed. In addition, the browser 221 outputs information on operations performed on the touch panel 212 superimposed on the display unit 211 to the SNS server 10. This operation information includes the search condition input in the field 220.

On the SNS server 10 side, the reception unit 125 receives information on operations performed on the touch panel 212 from the browser 221 or the operation detection unit 222.
The specifying unit 126 accesses the database 108 in the storage unit 106 in accordance with information received by the receiving unit 125 and instructions of the display control unit 123 and the management unit 127, and reads and transfers necessary information. Or write.
The display control unit 123 creates web screen information in which a program describing display control is embedded, and transmits the web screen information to the terminal device 20. Thereby, in the terminal device 20, since the browser 221 analyzes web screen information and displays a web screen on the display unit 211, the display control unit 123 in the SNS server 10 indirectly displays the display on the display unit 211 in the terminal device 20. Control.
The management unit 127 manages the transmission and reception of messages to the users constituting the group. This management includes disabling the transmission of messages among users of the group.

In the figure, an arrow heading from the display control unit 123 to a device other than the terminal device 20 indicates that information is also output to a terminal device other than the terminal device 20. The heading arrow indicates that information is also input from another terminal device 20.
Next, a table and a storage unit stored in the database 108 will be described.

<User registration table>
FIG. 5 is a diagram illustrating an example of the user registration table TB1.
As shown in this figure, in the user registration table TB1, member ID, user ID, user name information, avatar information, profile image, age information, member type information, and residence information Are stored in association with each member.
Among these, the member ID is information for uniquely identifying the SNS member by, for example, a plurality of alphanumeric characters. The user ID is information that uniquely identifies the user who receives the message transmission / browsing service within the system 1, and a serial number is used in the example of the figure. Here, since it is assumed that some members receive provision of the message transmission / viewing service, the member ID and the user ID are managed separately. The user name information indicates a name used when calling between users in the SNS, and a real name or a nickname is used. The avatar information indicates an avatar image representing the user, and the profile image indicates an image indicating the user, and any of them selected or edited by the user is used. The avatar information and the profile image may be the link destination (reference destination) of the entity, not the entity itself. In any case, it suffices if a means for acquiring the avatar information and the profile image from the user ID or the like is taken.

  The age information indicates the age of the member. The age information is not the age itself, but the member belongs to any age category such as 16 to 18 years old, 18 to 20 years old, 20 to 25 years old, 25 to 30 years old It may be information indicating whether or not. Moreover, the information which shows whether it is a young person may be sufficient.

The member type information indicates whether the member is a regular member or an associate member, for example.
Here, the regular member refers to a member whose restriction is not imposed on the service provided by the SNS. In order to become a regular member, it is generally necessary to register personal information (real name, name used in SNS, gender, age, date of birth, address, telephone number, e-mail address, etc.) in SNS.
The associate member refers to a member who receives a service provided by SNS on a trial basis with a provisionally issued account, and the service provided by SNS is limited compared to a regular member. In addition, the associate member includes, for example, a person who logs in using an account of a service other than the SNS instead of the temporarily issued account. Since the associate member only needs to register a part of personal information (for example, gender and name) in the SNS, the threshold for registration is lowered.

  Here, only regular members and associate members can receive the message transmission / viewing service. In this description, for example, a member under the age of 18 is treated as a young person, and a member over the age of 18 is treated as an elder (non-young). Associate members are treated the same as younger people, regardless of age, in the sense of restricting services.

By the way, in this embodiment, the message transmission / browsing service is executed in units of groups formed by a plurality of users.
Here, when creating a group, if there are only two users who are members of a stranger and at least one of them is a juvenile person, it is in an unfavorable state in terms of crime prevention and morals. I can say that. For this reason, in this embodiment, such a state is not created when creating a group.
Similarly, when a user withdraws from a group, the remaining users who are part of the group due to withdrawal are only two strangers, and at least one of them is a juvenile person. It can be said that it is in a state. For this reason, in the present embodiment, such a state is not created in managing the group, such as withdrawal.

  In the user registration table TB1 shown in FIG. 5, the residence information is information indicating a member's address or residence. As described above, since the registration of age and place of residence is not a requirement for associate members, “−” indicating “not entered” (unregistered) is shown in FIG.

<Group registration table>
As described above, the message transmission / viewing service is executed in units of groups. One group is composed of two or more users, and any user is a member of this SNS. The group registration table TB2 manages such group registration.

  FIG. 6 is a diagram illustrating an example of the group registration table TB2. As shown in this figure, in the group registration table TB2, a group ID for uniquely identifying a group, a name of the group, and five user IDs from A to E as members constituting the group are groups. It is stored in association with each other. The group member <null> indicates an unset empty state.

  Here, in the example of FIG. 6, the group indicated by the arrow has the group ID “xxx1”, the group name “Gamers”, and the user IDs “3”, “5”, “2”. , “8” is composed of four users. Here, for users with user IDs “3”, “5”, “2”, and “8”, necessary information can be acquired by referring to the user registration table shown in FIG. it can.

<Friend relationship storage table>
In the SNS, as described above, various games are provided to members. This game includes a self-contained game that is completed only by an individual and does not require cooperation with others, and a social game that is played while communicating with other members. The friend relationship storage table TB3 stores the relationship between users who have met in such a social game for each game, or stores the relationship between users who are acquainted in the real world.
In addition, although the friend relationship between users is memorize | stored in connection with each other by the information (user ID or member ID) which identifies a user, description is abbreviate | omitted about the specific memory | storage form.

<Post / Response History Storage Unit>
In the system 1, a service that a message transmitted by a member of the group is displayed in order of transmission time is provided to each member constituting the group.
Here, in addition to the text information that is the body of the message, the “message” includes a user ID that uniquely identifies the sender, outgoing date information that indicates the outgoing date of the message, avatar information of the sender's avatar, The motion ID for uniquely identifying the motion information that defines the motion of the avatar is included.

An avatar is a kind of character image that represents a sender (user). For example, the avatar is created / selected in advance before a message is transmitted, and is registered in the SNS server 10, for example. Thereby, an avatar is associated with each user. The avatar is configured to be deformed by blocks corresponding to, for example, the head, torso, both hands, and both feet, and movement is given to these joints according to certain rules.
In the following, attention is paid to a specific terminal device 20 and the operation of the terminal device 20 and the SNS server 10 will be described. Therefore, the user of the focused terminal device 20 can be used by other terminal devices 20. In particular, it may be called “subject” to distinguish it from a person.

Strictly speaking, there are two types of message transmission: “post” and “response”. Among these, “posting” means that the subject or another user sends (transmits) a basic message. Also, “response” means that another user or subject replies with a message to a certain post (or response). Therefore, the “response” always has a basic “post”. Note that another “response” may occur in response to the “response”.
However, in the present embodiment, “posting” and “response” are not distinguished as simply message transmission unless particularly required as follows.

In this embodiment, when a subject or another user “posts” a message, the message uniquely identifies the character information constituting the message, the user ID of the poster, and the “post”. The post ID and the transmission date and time (date and time) are stored in the post / response history storage unit 118 in association with each other. Strictly speaking, there is a case where character information (main body information) is not included in the message as will be described later, and on the other hand, there is a case where motion information (accompanying information) that defines the operation of the avatar is associated. .
When the subject or another user responds to the “post” with a message, the message is added to the post ID of the “post” that is the basis of the “response” and the user ID of the poster. In addition, the post ID is stored in the post / response history storage unit 118 in association with the user ID of the responder, the response ID that uniquely identifies the “response”, and the transmission date and time.
In this way, a post / response history is one in which zero or one or more “responses” are sequentially linked to one “post”. The posting / response history storage unit 118 in the database 108 stores such posting / response history in association with, for example, a group. The specific storage mode of the post / response history is not particularly related to the present invention, and will not be described.

  Next, an operation when message processing for providing a message transmission / browsing service is executed in the system 1 will be described.

FIG. 7 is a flowchart showing the message processing operation, and FIGS. 8 and 9 are flowcharts showing the group management processing operation in the message processing.
First, in the terminal device 20, when a user performs a predetermined operation to execute message processing, for example, when an icon indicating the function is tapped on a main menu screen (not shown), the terminal device 20 The operation detection unit 222 detects the tap and notifies the SNS server 10 that a message processing activation instruction has been issued.
In the SNS server 10, when the receiving unit 125 receives the notification of the activation, the notification is transferred to the specifying unit 126. The specifying unit 126 accesses the group registration table TB2 and determines whether or not there is a group including the user of the terminal device 20 as a member (step Sa11).

If the group does not exist (if the determination result in step Sa11 is “No”), the processing procedure proceeds to step Sa20 described later. On the other hand, if the group exists (if the determination result in step Sa11 is “Yes”), the identifying unit 126 reads all the information of the group that has the user of the terminal device 20 as a member, and based on the information The display control unit 123 is instructed to create a messenger top screen. The display control unit 123 is a screen information based on the read information, creates a messenger top screen with web screen information in which a program describing the control of the screen is embedded, and transmits the messenger top screen to the terminal device 20 that has notified the activation. To do.
In the terminal device 20, the browser 221 analyzes the web screen information and displays the messenger top screen on the display unit 211 (step Sa12).

FIG. 10 is a diagram illustrating an example of a messenger top screen.
As shown in this figure, in the display unit 211 of the terminal device 20, the group in which the user of the terminal device 20 is registered as a member is the name, the profile image of the member, and the last comment date and time by the member of the group. For example, the list is displayed in the order of the latest posting / response.
The button 231 is a software button for instructing creation of a new group.
In the area 232, “Notification” related to the user of the terminal device 20 is notified. For example, when the display portion of this area 232 is tapped, another screen is opened and details about “Notification” are displayed.
The mark 233 indicates that there is a message that the user of the terminal device 20 has not yet browsed in the group to which the mark 233 is attached.
Each of the buttons 234, 235, and 236 is a software button displayed corresponding to each group. Of these buttons, the button 234 is used to instruct movement of the corresponding group to view the message, and the button 235 is used to instruct to edit the group. The button 236 is used from the group. Instructs withdrawal.
The button Fin instructs the end of this message processing.

In each group, the thick frame surrounding the profile image of the member at the left end indicates the manager (creator) of the group.
Even when there are many groups and the display unit 211 cannot display them all at once, for example, if an operation such as flicking or moving the slide bar 237 is performed, the display is scrolled up and down. In addition, the display order of each group is not limited to the order in which the latest posting / response was received, but may be the order of group creation (newest order, oldest order), the order of most group members, or the order of fewness.

On such a messenger top screen, the browser 221 determines from the detection result of the operation detection unit 222 whether or not an appropriate operation has been performed on the touch panel 212 (step Sa13). Here, the appropriate operation refers to an operation on a button display portion or region where a tap or flick is assumed. If there is no operation, or if the operation is an invalid operation that is not expected even if there is an operation (if the determination result in step Sa13 is “No”), the processing procedure returns to step Sa12. For this reason, the display of the messenger top screen is continued until some appropriate operation is performed.
When an appropriate operation is detected by the operation detection unit 222 (when the determination result in step Sa13 is “Yes”), the browser 221 indicates that the operation is to be ended, that is, an operation on the display portion of the button Fin. It is determined whether or not there has been (step Sa14).

If it is an instruction to end (if the determination result in step Sa14 is “Yes”), this message processing ends and the screen returns to the main menu screen (not shown).
On the other hand, if the instruction is not an end instruction (if the determination result in step Sa14 is “No”), the browser 221 goes to a group selection instruction, that is, the display portion of the button 234 corresponding to any group. It is determined whether or not the operation has been performed (step Sa15).
If the operation is selection of a group (if the determination result in step Sa15 is “Yes”), the processing procedure proceeds to step Sa16. If the operation is not a group selection (if the determination result in step Sa15 is “No”), the processing procedure proceeds to step Sa20.

In step Sa20, the group management process shown in FIGS. 8 and 9 is executed.
First, in the group management process, the browser 221 determines whether or not the operation performed on the messenger top screen is an instruction to create a new group, that is, an operation on the display portion of the button 231 (step Sb11).
If it is not an instruction to create a new group (if the determination result in step Sb11 is “No”), the processing procedure proceeds to step Sb51 described later. On the other hand, if it is an instruction to create a new group (if the determination result in step Sb11 is “Yes”), the browser 221 notifies the SNS server 10 that the instruction has been made. In the SNS server 10, when the receiving unit 125 receives the instruction, the instruction is transferred to the specifying unit 126. The specifying unit 126 accesses the friend relationship storage table TB3, reads out information on a user who has a friend relationship with the user of the terminal device 20, and displays that a friend top screen should be created based on the information. The controller 123 is instructed. The display control unit 123 is a screen information based on the read information, creates a friend top screen with web screen information in which a program describing the control of the screen is embedded, and notifies the terminal device 20 that has notified the instruction. Send.
In the terminal device 20, the browser 221 analyzes the web screen information and displays the friend top screen on the display unit 211 (step Sb12).

Before explaining the friend top screen, when creating a new group, it is necessary to know candidates (candidate users) who can be members of the group. In this embodiment, it is assumed that the member candidates are selected from three types of SNS friends, game friends, and persons obtained from search results.
Here, the SNS friend is a member of the SNS and a member who is acquainted in the real world. A game friend is a member of the SNS who communicates in a social game provided by the SNS. The search result is a result obtained by searching the entire user from attribute information such as the user's name and residence. The search result is assumed to be used when it cannot be found by an SNS friend or a game friend.

FIG. 11 is a diagram illustrating an example of the friend top screen.
As shown in this figure, buttons 241, 243 and 245 are displayed on the display unit 211. In a region 242 between the display portions of the buttons 241 and 243, a list of games in which the user of the terminal device 20 participates as a stage before selecting candidates who can be members of the group from the game friends. Is displayed. Here, if there are many participating games that cannot be displayed at once, for example, if the slide bar 244 is moved or the list display portion is flicked, the display is scrolled up and down.
The button 241 is a software button for instructing a transition to a list screen for selecting a candidate who can be a member of the group from the SNS friend by the operation. The button 243 is a software button for instructing a transition to a search screen for searching for candidates who can become members of the group by the operation. The button 245 is a software button for instructing to return to the messenger top screen by the operation.

In such a friend top screen, the browser 221 determines whether or not an appropriate operation has been performed on the touch panel 212 (step Sb13). If there is no operation or if it is an invalid operation even if there is an operation (if the determination result in step Sb13 is “No”), the processing procedure returns to step Sb12. Until the friend top screen is displayed.
When an appropriate operation is performed (when the determination result of step Sb13 is “Yes”), the browser 221 determines whether the operation is an operation on the display portion of the button 241 or the region 242. (Step Sb14).
If the operation is not an operation on the display portion of the button 241 but an operation on the area 242 (if the determination result in Step Sb14 is “No”), the operation is performed on the display portion of the button 243 or the button 245. Operation. For this reason, a process sequence transfers to step Sb31 mentioned later.

  On the other hand, if the operation is an operation on the display portion of the button 241 or an operation on the area 242 (if the determination result in step Sb13 is “Yes”), the operated display portion is as follows. A friend list screen corresponding to is displayed (step Sb15).

  Specifically, if the operation is on the display portion of the button 241, the browser 221 notifies the SNS server 10 of the notification of the operation. On the SNS server 10, when the receiving unit 125 receives the notification, the browser 221 notifies the notification. Transfer to the identification unit 126. The specifying unit 126 specifies a user (user ID) that is in a SNS friend relationship with the user (user ID) of the terminal device 20 by accessing the friend relationship storage table TB3 and specifies the specified use. The user's name and profile image are acquired by accessing the user registration table TB1. The specifying unit 126 instructs the display control unit 123 to create an SNS friend list screen based on these pieces of information. The display control unit 123 is the web screen information based on these pieces of information, and creates the SNS friend list screen with the web screen information in which the program describing the control of the screen is embedded. Send to. In the terminal device 20, the browser 221 analyzes the web screen information and causes the display unit 211 to display the SNS friend list screen.

If the operation is to the area 242, the browser 221 notifies the SNS server 10 of information indicating which game display part has been operated among the displayed games. On the other hand, in the SNS server 10, when the receiving unit 125 receives the information, the information is transferred to the specifying unit 126. The specifying unit 126 specifies a user who is in a game friend relationship with the user of the terminal device 20 by accessing the friend relationship storage table TB3, and specifies the name of the specified user and A profile image is acquired by accessing the user registration table TB1. The specifying unit 126 instructs the display control unit 123 to create a game friend list screen based on these pieces of information, and the display control unit 123 uses the web screen information to display the game friend list screen based on these pieces of information. Thus, the browser 221 causes the display unit 211 to display the game friend list screen.
In FIG. 8, steps Sb15 and Sb16 and further steps Sb17 and Sb18 should be described separately for the SNS friend list screen and the game friend list screen, but the processing contents are similar. It explains in common.

FIG. 12 is a diagram illustrating an example of the SNS friend list screen, and FIG. 13 is a diagram illustrating an example of the game friend list screen.
Note that the game friend list screen shown in FIG. 13 is a game communicated in the game when the display portion of the game “dragon collection” in the area 242 is operated in the friend top screen shown in FIG. It is an example of a friend list display.

Further, hereinafter, when the SNS friend list screen and the game friend list screen are not distinguished, they may be simply referred to as a friend list screen. In the friend list screen shown in FIG. 12 or 13, candidates that can be members of the group are displayed in a list, and a check box 250 for selection is displayed for each candidate.
On the friend list screen, buttons 251, 252, and 253 are displayed. Of these, the button 251 is a software button for instructing clear all of candidates checked in the check box 250. The button 252 is a software button for confirming the check on the check box 250 and instructing that a group is created by the checked candidate. The button 253 is a software button for instructing to close the friend list screen and return to the friend top screen.
Even when there are a large number of candidates and the display unit 211 cannot display them all at once, for example, if an operation such as flicking or moving the slide bar 254 is performed, the display is scrolled up and down.
In addition, the candidates may be limited to a part, such as 30 people who are not close to the SNS friends, and 30 people who are close to the residence, or 30 people who have recently communicated.

Now, in the friend list screen shown in FIG. 12 or FIG. 13, the browser 221 determines whether or not an appropriate operation has been performed (step Sb16). When the operation is not performed, or when the operation is invalid even when the operation is performed (when the determination result of step Sb16 is “No”), the processing procedure returns to step Sb15. For this reason, the display of the friend list screen continues until any appropriate operation is performed.
On the other hand, when an appropriate operation is performed (when the determination result of step Sb16 is “Yes”), the browser 221 causes the operation performed on the friend list screen to tap the display portion of the candidate. It is determined whether or not the selection operation has been performed (step Sb17).
If the operation is not a selection operation (if the determination result in step Sb17 is “No”), the processing procedure proceeds to step Sb19 described later.

On the other hand, when the operation is a selection operation (when the determination result of step Sb17 is “Yes”), the browser 221 is a candidate for the operation if the operation is a check operation. On the other hand, if the selected operation is a check state in which the check mark is placed in the check box 250 of the candidate for the operation, (Step Sb18).
Thereafter, the processing procedure returns to step Sb15, whereby a friend list screen with a check or uncheck is displayed.

If the operation on the friend list screen is not a selection operation, the browser 221 determines whether or not the operation is an operation on the display portion of the button 251 (step Sb19). If the operation is an operation on the display portion of the button 251 (if the determination result in step Sb19 is “Yes”), the browser 221 displays a check mark in the check box 250 in the friend list displayed on the screen. All the display states are removed, and among the candidates registered in the check list, the candidates registered on the friend list screen are deleted (step Sb20). The check list will be described later.
Thereafter, the processing procedure returns to the display of the friend top screen in step Sb12. The return destination of the processing procedure may not be the friend top screen, but the friend list screen with all check marks removed.

On the other hand, if the operation on the friend list screen is an operation on the display portion of the button 251 (if the determination result in step Sb19 is “No”), the operation is an operation on the display portion of the button 252 or the button 253. is there. Therefore, the browser 221 determines whether or not the operation is an operation on the display portion of the button 252 (step Sb21).
If the operation is not an operation on the display portion of the button 252 (if the determination result in step Sb21 is “No”), it means that the operation is on the display portion of the button 253. Return to the display of the friend top screen in Sb12.

If the operation is an operation on the display portion of the button 252 (if the determination result in step Sb21 is “Yes”), the browser 221 is a candidate selected on the friend list screen at the time of the determination. Is registered in the check list (step Sb22).
Here, the check list is a list indicating candidates selected when the confirmation button 252 is operated after the terminal device 20 is checked. This check list includes a list of candidates checked on the friend list screen shown in FIGS. 12 and 13 and the friend search result screen shown in FIG. 15 to be described later. Note that since the members of the group are composed of candidates who are finally registered in the check list and the selected user (subject), the subject is not registered in the check list.
Thereafter, the browser 221 displays a confirmation screen as to whether or not to create a group whose members are candidates registered in the check list, although illustration of the screen is omitted (step Sb23). When instructed (when the determination result of step Sb23 is “Yes”), the group name input on the separate screen and the registered content of the checklist are transmitted to the SNS server 10. If the number of people registered in the check list is zero at that time, the browser 221 displays a warning to that effect on the display unit 211. On the other hand, in the SNS server 10, when the receiving unit 125 receives the registration content and the like, the registration content is transferred to the specifying unit 126. The specifying unit 126 includes the user of the terminal device 20 that transmitted the registration content and the candidate and the candidate indicated by the registration content as members, and adds the input name group to the group registration table TB2. As a result, a group including the user of the terminal device 20 and the user registered in the checklist is created (step Sb24).
Thereafter, the processing procedure returns to step Sa11 in FIG.

  When it is instructed not to create a group on the confirmation screen (when the determination result of step Sb23 is “No”), the browser 221 displays a processing procedure with a button 252 as indicated by * in the figure. Return to the friend list screen where is operated. Specifically, if the button 252 on the SNS friend list screen (see FIG. 12) or the game friend list screen (see FIG. 13) is operated, the processing procedure returns to step Sb15, and the friend search result screen (FIG. 15 or If the button 252 in FIG. 16 is operated, the processing procedure returns to step Sb32.

  In addition, after step Sb24, since the group which makes the subject person of the said terminal device 20 a member is produced, the determination result of step Sa11 becomes "Yes" after that. In the messenger top screen in the next step Sa12, the created group is added to the list and displayed.

The SNS friend communicates with the user of the terminal device 20 in the real world and the game friend in the virtual society. Therefore, these friends are not in a relationship that does not know at all about the user of the terminal device 20.
For this reason, even if it is a young person about a SNS friend and a game friend, the structure of the group by only two persons with the user (subject) of the said terminal device 20 is accept | permitted. However, as will be described later, the candidate obtained by the search may not know the user of the terminal device 20. For this reason, if the candidate obtained by the search is a young person, the group configuration by only two people with the user of the terminal device 20 is prohibited.

  In this embodiment, for convenience of explanation, when a user other than the terminal device 20 in which the button 252 is operated is registered in the group, the consent by the user is not asked, but the consent by the user may be used as a condition. . Although details will be described later, when adding a group to the group registration table TB2, the management unit 127 sends an email to the user to confirm the registration to the group, and permits the registration to the group. A configuration may be adopted in which only users who have received a reply to the effect are registered in the group.

By the way, when the operation on the friend top screen is not an operation on the display portion of the button 241 and is not an operation on the area 242, the browser 221 determines whether or not the operation is an operation on the display portion of the button 243. (Step Sb31). If the operation is not an operation on the display portion of the button 243 (if the determination result in step Sb31 is “No”), the operation is an operation on the display portion of the button 245. For this reason, the processing procedure returns to step Sa11 in FIG.
On the other hand, if the operation is an operation on the display portion of the button 243 (if the determination result of step Sb31 is “Yes”), the browser 221 displays the number of candidates currently registered in the checklist. Whether or not is zero is determined (step Sb32).

When the number of candidates registered in the checklist is 0, the browser 221 is set to prohibit selection of candidates who are juveniles or associate members on a screen for displaying a later search result ( Step Sb33). In addition, the object of selection prohibition is a young person or an associate member to the last, and an elder person (non-young person) is excluded from an object.
On the other hand, when the number of candidates registered in the checklist is one or more, the browser 221 is configured to cancel the selection prohibition of candidates who are juveniles or associate members on a screen for displaying a later search result. (Step Sb34).
After the settings in Steps Sb33 and Sb34, the browser 221 displays a search screen on the display unit 211 (Step Sb35).

FIG. 14 is a diagram illustrating an example of a search screen.
As shown in this figure, a field 220 and buttons 253 and 261 are displayed on the search screen. Among these, the field 220 is an area for inputting a search condition. When this field 220 is tapped, a software keyboard is separately displayed (not shown), thereby enabling input of search conditions. The button 261 is a software button for instructing a search with the search condition input in the field 220. Here, as a search condition, a part or all of a candidate's name, a residence, etc. are mentioned. Further, if an item such as a member's hobby is added to the user registration table TB1, this item may be used as a search condition.
The area 260 is an area where search results are displayed.

In this search screen, the browser 221 determines whether or not an appropriate operation has been performed on the touch panel 212 (step Sb36). When the operation is not performed, or when the operation is invalid even when the operation is performed (when the determination result of step Sb36 is “No”), the processing procedure returns to step Sb35. For this reason, the display of the search screen continues until any appropriate operation is performed.
On the other hand, when any appropriate operation is performed (when the determination result of step Sb36 is “Yes”), the browser 221 performs an operation performed on the search screen in a state where the search condition is input in the field 220. It is determined whether or not the operation is on the display portion of the button 261 (step Sb37).

If the operation performed on the search screen is not an operation on the display portion of the button 261 or the like (if the determination result in step Sb37 is “No”), the processing procedure proceeds to step Sb39 described later.
If the operation performed on the search screen is an operation on the display portion of the button 261 or the like (if the determination result in step Sb37 is “Yes”), the browser 221 uses the search condition input in the field 220. Is transmitted to the SNS server 10. On the other hand, in the SNS server 10, when the receiving unit 125 receives the search condition, the search condition is transferred to the specifying unit 126. The specifying unit 126 accesses the user registration table TB1, reads information on regular members and associate members that satisfy the search conditions, and instructs the display control unit 123 to create a friend list screen of these search results. At this time, the read member information includes a user name, a user profile image, age information, and member type information.
The display control unit 123 is screen information based on the read information, and creates a friend list screen with web screen information in which a program describing the control of the screen is embedded, and transmits the search condition to the terminal device 20 Reply to
In the terminal device 20, the browser 221 analyzes the web screen information and displays the friend list screen in the area 260 in the display unit 211 (step Sb38).

FIG. 15 is an example of a search result in which a list screen is displayed in the area 260, and candidates that satisfy the search condition are listed together with the check box 250.
When any operation is performed on the search result screen or the search screen illustrated in FIG. 14, when the operation is not an operation on the display portion of the button 261, the browser 221 determines that the operation performed is a candidate. It is determined whether or not the selection operation is such that the display portion of the person is tapped (step Sb39).
If the operation is not a selection operation (if the determination result in step Sb39 is “No”), the operation is an operation on one of the display portions of the buttons 251, 252, and 253. The process proceeds to step Sb19 described above.

On the other hand, when the operation is a selection operation (when the determination result of step Sb39 is “Yes”), the browser 221 is a candidate for the operation if the operation is a check operation. On the other hand, if the operation is an unchecked operation, the check box in the candidate's checkbox related to the operation is removed (unselected state). Step Sb40). Thereafter, the processing procedure returns to Step Sb32.
In addition, regarding the registration of the selected candidate in the check list or the deletion of the non-selected candidate from the check list, the operation to the button 252, that is, the processing procedure is performed from step Sb 39 to Sb 19. → Sb21 → Sb22 is executed by proceeding.

  Here, the example of the friend search result screen shown in FIG. 15 is a case where an operation is performed on the display portion of the button 261 after “Yes” is input in the field 220 as a search condition. In the state where no one is registered, that is, when there are 0 registered candidates, an example is shown in which there are 5 users who include “Yes” in part or all of their names. Yes.

Until this friend search result screen is set, the selection of the candidate who is a junior or associate member in step Sb33 described above is prohibited, so as shown in FIG. A mark 255 indicating that it is not possible to select a juvenile or associate member is displayed instead of a check box.
On the other hand, check boxes 250 are displayed for the regular members of the elders as in the SNS friend list screen and the game list screen. Here, when the selection operation for checking the check box 250 of any one of the elder members among the five members is performed, the processing procedure is step Sb35 → Sb36 → Sb37 → Sb39 → Sb40 → Sb32 → Sb33 → Proceed in the order of Sb35. When the button 253 is operated in this state, the processing procedure proceeds in the order of steps Sb36 → Sb37 → Sb39 → Sb19 → Sb21 → Sb22 → Sb23 → Sb32. For this reason, since there is one candidate registered in the check list, the determination result in step Sb32 is “No”. Accordingly, in step Sb34, the selection prohibition of the candidate who is a juvenile or an associate member is set to be canceled, so that the next friend search result screen is for the juvenile or associate member as shown in FIG. Is switched from the mark 255 to the display of the check box 250. For this reason, after that, it becomes possible to select a junior or associate member as a member of the group.
In addition, when an operation for removing the check box 250 is performed in the example of the screen shown in FIG. 16, the number of candidates registered in the check list is 0, so that selection for candidates who are juveniles or associate members is possible. It is prohibited (step Sb33). For this reason, as shown in FIG. 15 again, the screen is switched to a screen in which a young person or associate member cannot be selected.

Thus, in this embodiment, when users who satisfy the search condition are displayed on the friend search result screen, the number of candidates registered in the checklist is zero (the determination result in step Sb32 is “Yes”). ”), The selection of candidates who are juveniles or associate members is prohibited (step Sb33). After that, when one or more senior members of the senior member are registered in the check list (if the determination result in Step Sb32 is “No”), the selection prohibition of the candidate who is a junior or associate member is lifted ( Step Sb34).
Therefore, in this embodiment, even if the user of the terminal device 20 tries to create a group with himself and one of the young people or associate members obtained by the search, the young people or the like are candidates for the group. Can not be selected as. For this reason, it becomes possible to prevent message exchanges such as one-on-one with young people.
On the other hand, if at least one regular member of the elder is registered in the checklist, the change is made so that the juvenile or the like can be selected as a candidate. For this reason, the message exchange in the group of three or more persons including the user of the terminal device 20 and other users as well as other users is allowed.
Moreover, in this embodiment, the target person who blocks the message exchange which becomes one-on-one with the user of the terminal device 20 includes not only young people but also associate members. For this reason, as shown in FIG. 15, even if a candidate with the mark 255 is displayed, whether the candidate is a young person or an associate member including an elderly person is used in the terminal device 20. Since a person cannot identify at a glance, it can be said that it is a preferable configuration from the viewpoint of training young people and crime prevention.

The registered contents of the checklist are cleared by operating the button 252 after the operation of removing the check in the check box 250 or after the operation of the button 251. Otherwise, the registered contents are not cleared. .
For this reason, for example, after selecting a candidate on the SNS friend list screen and operating the button 252 to register the selected candidate in the check list, the screen is switched to the game friend list screen and another candidate is selected. When the button 252 is operated, the other candidate is added to the check list and registered. Furthermore, when the display part of the button 253 is operated on the game friend list screen to move to the friend search screen via the friend top screen, when a candidate is selected from the search result and the button 252 is operated, the candidate Those who are registered are added to the checklist and registered. In this way, when multiple candidates are selected across multiple screens, the candidates selected on other screens are added to the checklist for the checklist obtained by selecting candidates on one screen. It is a configuration to be added.
Therefore, when one or more candidates are registered in the checklist on the SNS friend list screen or the game friend list screen, when the search result is obtained by moving to the friend search screen, Instead of the mark 255 indicating that selection is not possible, a check box 250 indicating that selection is possible is displayed.

By the way, if the operation performed on the messenger top screen is not an operation for instructing the creation of a new group (if the determination result in step Sb11 is “No”), the browser 221 instructs the editing of the group. It is determined whether or not the operation has been performed (step Sb51). The operation for instructing group editing is, for example, when the button 235 corresponding to the group desired to be edited is operated.
If the operation is an operation for instructing editing of a group (if the determination result in step Sb51 is “Yes”), the browser 221 displays a group editing screen on the display unit 211 (step Sb52).
Note that the group editing screen is not important for understanding the present invention, and will be briefly described. The browser 221 transmits the contents edited on the group editing screen to the SNS server 10, while the SNS server 10 When the receiving unit 125 receives the editing content, the editing content is transferred to the specifying unit 126. The identifying unit 126 reflects the edited contents on the group registration table TB2 (step Sb53).

On the other hand, when the operation performed on the messenger top screen is not an operation for instructing the creation of a new group and an operation for instructing the editing of the group (when the determination result in step Sb51 is “No”), the browser 221 Then, it is determined whether or not the operation is an instruction to withdraw from the group (step Sb54). The operation for instructing the withdrawal of the group is, for example, when the button 236 corresponding to the group desired to be withdrawn is operated.
If the operation is an operation to instruct the withdrawal of the group (if the determination result of step Sb54 is “Yes”), the browser 221 transmits the information of the group for which the withdrawal is desired to the SNS server 10, while the SNS In the server 10, the receiving unit 125 transfers the information on the group and the information on the user of the terminal device 20 that transmitted the information to the specifying unit 126. The specifying unit 126 accesses the group registration table TB2, acquires information about the group, and transfers the information to the management unit 127 (step Sb55).

When the user of the terminal device 20 withdraws from the group, the management unit 127 determines whether the remaining number of members is three or more (step Sb56). If the remaining number of members is three or more (if the determination result in step Sb56 is “Yes”), the management unit 127 reflects the withdrawal of the user (step Sb57). Specifically, the management unit 127 instructs the specifying unit 126 to withdraw, and upon receiving this instruction, the specifying unit 126 accesses the group registration table TB2 and deletes the user from the group. .
In the present embodiment, even if a certain user withdraws from a group that has been a member, the user's message is not deleted from the posting / response history of the group but remains as it is.

On the other hand, if the remaining number of members is not three or more (if the determination result in step Sb56 is “No”), the management unit 127 determines whether or not the number of members is one (step Sb58). . If the number is not one (if the determination result in step Sb58 is “No”), it indicates that the remaining number of members is two. At this time, the management unit 127 determines whether or not at least one of the remaining two persons is a juvenile or an associate member (step Sb59). If one of the two is a juvenile or associate member (if the determination result in step Sb59 is “Yes”), there is an inconvenience that messages are exchanged one-on-one with the juvenile or associate member. Since it means that it occurs, it is ex post facto, but it is not preferable from the viewpoint of training young people and crimes and crime prevention. Therefore, in this embodiment, the group is forcibly dissolved (deleted). Specifically, the management unit 127 instructs the specifying unit 126 to delete the group, and upon receiving this instruction, the specifying unit 126 accesses the group registration table TB2 and deletes the group ( Step Sb60). Therefore, the management unit 127 cannot use the group thereafter.
In addition, the management unit 127 transmits an email to the effect that the group has been dissolved to the users who have constituted the group until immediately before withdrawal. Note that the terminal device 20 that has received this mail is notified as “notification” in the area 232 of the display unit 211.

In addition, if at least one of the remaining two members is not a juvenile member or an associate member, that is, if both of them are regular members and senior members (if the determination result in step Sb59 is “No”), the above Since it is not necessary to consider inconvenience, the processing procedure shifts to step Sb57 described above, and the withdrawal of the user is reflected.
On the other hand, when the remaining number of persons is one (when the determination result of step Sb58 is “Yes”), the group is no longer part of the group. For this reason, the processing procedure shifts to step Sb60 described above, and the dissolution processing of the group is executed.

Note that the operation performed on the messenger top screen shown in FIG. 10 is not an operation for instructing creation of a new group, an operation for instructing editing of a group, or an operation for instructing withdrawal of a group (step If the determination result of Sb54 is “No”, the browser 221 executes a process according to the content of the operation (step Sb61). As an example of such a process, there is a process of scrolling and displaying a display part of a list of groups when the display part is flicked.
After the processing of steps Sb53, Sb57, Sb60, and Sb61, the processing procedure returns to step Sa11 in FIG.

  Now, when the display portion of the button 234 corresponding to a certain group is tapped on the messenger top screen, processing for displaying the message content transmitted by the member of the group is executed (step Sa16).

The details are as follows.
That is, first, the browser 221 transmits information specifying the group corresponding to the tapped button 234 to the SNS server 10. Secondly, in the SNS server 10, when the receiving unit 125 receives the information, the information is transferred to the specifying unit 126. The identifying unit 126 identifies the member of the group by accessing the group registration table TB2. Thirdly, the specifying unit 126 reads the posting / response history related to the member from the posting / response history storage unit 118 and transfers it to the display control unit 123, and instructs creation of a message display screen. 4thly, the display control part 123 produces a message display screen with the web screen information based on these information, and replies to the terminal device 20 which transmitted the information which identifies a group. The display control unit 123 reads information necessary for creating the message display screen (for example, an avatar, profile image, motion information, etc. described later) from the user registration table TB1 via the specifying unit 126, and controls the screen. For example, a program describing a motion to be given to an avatar is embedded in the web screen information. Fifth, in the terminal device 20, the browser 221 analyzes the received web screen information and causes the display unit 211 to display a message display screen.

The message display screen will be specifically described. The message includes character information, a user ID, transmission date information, and an operation ID as described above. From these pieces of information, the display control unit 123 causes the message display screen based on the posting / response history to alternate left and right in the order of the transmission date and time, as shown in FIG. Are created so that messages are arranged and displayed as units. Specifically, as shown in the figure, the display control unit 123 is the second one when the display (1) of the message transmitted first in a group is arranged at the upper right end point in the figure. The sent message display (2) is placed at a position diagonally to the left of the display (1), and the third sent message display (3) is placed to the right of the display (2). The message display is alternately arranged so as to be arranged at a diagonally lower point and so on.
In addition, it may be arranged so that the older transmission date and time is directed to the lower part of the screen, but here, for convenience, an example in which the newer one is arranged to be directed to the lower part of the screen as shown in the figure I will explain it.

In the present embodiment, it is assumed that the message includes character information and an action ID in one of three combinations of types (A), (B), and (C) for convenience in FIG.
That is, type (A) includes only character information, type (B) includes both character information and an operation ID, and type (C) includes only an operation ID.

The message display is as shown in the right column of the figure for the three combinations. Specifically, in type (A), a text based on character information is displayed in a balloon, and a profile image based on a user ID and time information transmitted based on transmission date information are each a balloon. It is displayed separately.
In the present embodiment, the case in which the operation ID is not included in the message is the type (A), but the case in which information indicating no operation ID is included in the message in advance and the information without the operation ID is included is included in the message. It is good also as a type (A).
In type (B), an avatar with motion is displayed together with a balloon, profile image, and time information similar to those of type (A). This avatar is defined by avatar information corresponding to the user ID, and this motion follows the motion information corresponding to the operation ID.
In type (C), since character information is not included, a balloon is not displayed, but an avatar with motion is displayed together with the profile image and time information, as in type (B).

Note that the size of the balloon and the arrangement of characters with respect to the balloon are appropriately controlled by the number of characters, line feeds, and the like.
Moreover, the right column of FIG. 17 is an example when the display of a message is arrange | positioned in the right spot on a screen. When the display of the message is arranged at the left point on the screen, the example of FIG. Moreover, when it is the message which self transmitted, about the profile image, it hides in the meaning which distinguishes from other members. Further, the color or shape of the balloon of a message transmitted by the user may be different from those of other balloons so as to be distinguished from other members.

  The operation ID is not an entity (motion information) but only information for identification, but the SNS server 10 corresponds to the operation ID for another table in the database 108 or for another server. By requesting motion information, actual motion information can be acquired.

When an avatar is displayed in types (B) and (C), in principle, the avatar is displayed so that the line-of-sight direction of the avatar is directed to the next remark. In other words, in a left-and-right alternating arrangement that goes to the bottom of the screen as the date and time of transmission are newer, in principle, the line of sight of the avatar arranged on the left side is diagonally downward to the right, while the line of sight of the avatar arranged on the right side is diagonally below the left Direction. However, the line-of-sight direction may be displayed so as to go to the previous statement.
As described above, in step Sa16, a message display screen showing the contents of messages transmitted by the members of the selected group in time series is displayed.

  FIG. 19 is a diagram showing an example of such a message display screen. In this figure, display (1-1) is an example of type (A), and each of displays (1-2) and (1-3) is an example of type (B). In this example, the avatars of display (1-2) and (1-3) correspond to the user who sent the message, respectively, and the user ID that sent the message in the posting / response history of the group. A corresponding avatar or an avatar corresponding to the user ID registered in the group registration table TB2 for the group is used.

By the way, in this embodiment, as mentioned above, a certain user may withdraw from the group. Here, on the screen shown in FIG. 19, for example, when the user who transmitted the message that is the source of the display (1-2) withdraws, there is a problem of what to do with the user's avatar.
When a user withdraws from a group, if the user's message is deleted from the posting / response history of the group, the contents will not be connected when the message display is arranged in chronological order. End up. On the other hand, even if the message of the user who has withdrawn is left without being deleted, there is a possibility that the remaining user may forget to leave (or not know) and respond to the message.
Therefore, in the present embodiment, for the message of the user who has withdrawn, the avatar and the profile image are displayed in a predetermined pattern, and other users have confirmed that the user who sent the message has withdrawn. The structure is obvious at first glance.
Here, the avatar and the profile image of the user who has withdrawn are configured to be painted black.

FIG. 20 is a diagram illustrating an example of a message display screen when there is a user who has withdrawn.
In this example, the user's avatar and profile image are painted black, but at least one of the avatar and the profile image may have a pattern and color different from those of other users.

By the way, as shown in FIGS. 19 and 20, in the message display screen, a field 270 and buttons 271 to 274 are displayed in addition to the message contents.
Among these, the field 270 is an area for inputting character information which is a message body. The button 271 is a software button for instructing to return to the previous messenger top screen. The button 272 is a software button for designating an action given to the avatar. The button 273 is a software button when a message transmitted in the past is used again. The button 274 is a software button for confirming the content of the message and instructing transmission. A button 275 is a software button for instructing message editing / information browsing.

  On the message display screen, the browser 221 determines whether or not there is any operation on the touch panel 212 (step Sa17 in FIG. 7). If there is no operation (if the determination result in step Sa17 is “No”), the processing procedure returns to step Sa16. For this reason, the process of steps Sa16 and Sa17 loops until some operation is performed, and the message display screen continues.

On the other hand, when any operation is performed (when the determination result in step Sa17 is “Yes”), the browser 221 inputs the operation to the field 270 or displays the buttons 272, 273, and 274 on the display portion. It is determined whether or not the tap has been made (step Sa18).
If the operation is an input to the field 270 or a tap on the display part of the buttons 272, 273, 274 (if the determination result in step Sa18 is “Yes”), the browser 221 responds to the operation. Processing is executed (step Sb19).
For example, in the case of input to the field 270, the browser 221 separately displays a software keyboard (not shown), and allows the user to input characters. If the button 272 is tapped, the browser 221 displays a menu screen (not shown) illustrating a plurality of operations such as “punch”, “kick”, “applause”, “banzai”, and the like, and displays the avatar. To specify the action to be given. If it is a tap on the button 273, the browser 221 displays a plurality of messages combining the text and operation ID transmitted in the past, and selects a message to be reused.

If it is a tap on the button 274, the content of the message is confirmed and transmission is instructed. Specifically, the browser 221 transmits a message in which the message body and the operation ID at the time of the instruction are combined to the SNS server 10. In the SNS server 10, when the receiving unit 125 receives the message, the message is transferred to the specifying unit 126. The identifying unit 126 records the message in the posting / response history storage unit 118 in association with the group. As a result, the message is added to the end of the posting / response history of the group.
After step Sa19, the processing procedure returns to step Sa16, and the message display screen (see FIG. 19) is displayed again. At this time, if a message is transmitted in step Sa19, the display of the message is added as the latest in time series.

  On the other hand, when an operation is performed on the message display screen and the operation is a tap on the buttons 271 and 275 (when the determination result in Step Sa18 is “No”), the browser 221 performs the operation. It is determined whether or not it is a tap on the display portion of the button 275 (step Sa21).

If the operation is not a tap on the display portion of the button 275 (if the determination result in step Sa21 is “No”), the operation is an operation on the display portion of the button 271.
Therefore, the processing procedure shifts to step Sa12 and returns to the display of the messenger top screen.
On the other hand, if the tap is on the button 275 (if the determination result in step Sa21 is “Yes”), the browser 221 displays a message editing / information browsing screen (step Sa22). If a predetermined operation is performed on the message editing / information browsing screen, the editing, browsing, and editing contents are reflected. Thereafter, the processing procedure returns to Step Sa16. Note that the message editing / information browsing screen is not important for understanding the present invention, and a description thereof will be omitted.

<Application and modification>
The present invention is not limited to the above-described embodiments, and various applications and modifications as described below are possible, for example. Note that one or a plurality of arbitrarily selected aspects of application / deformation described below can be appropriately combined.

<Attribute information / age information>
In the embodiment, the attribute information of the user such as the name and residence and the age information of the user are directly associated and stored in the user registration table as shown in FIG. Not limited to this configuration, in one table, user attribute information is stored in association with an ID that uniquely identifies the user, such as a user ID, while the user age information is stored in a separate table. A configuration may be used in which the ID information is stored in association with the ID, and one of the attribute information and the age information is indirectly specified via the ID. When the terminal device 20 is a mobile phone, the terminal device 20 is configured to check whether the mobile phone is a junior by inquiring of a management device that manages personal information at the time of a telephone contract in the telephone company. Also good.

<Error output>
In the embodiment, when selecting a group candidate, if the number of people registered in the checklist is 0, the selection of a young person (or associate member) is prohibited (step Sb33), When the number of people registered in the checklist becomes one or more, the setting for canceling the selection prohibition of younger members (semi-members) is set (step Sb34). Is possible.
That is, even if the number of people registered in the checklist is zero, it is possible to select a juvenile (associate member), but when a juvenile (or associate member) is selected, an error is shown in FIG. A message as shown in area 262 is output. Of course, no error is output when an active member is selected. For this reason, there is a possibility that a group of two users, ie, a user of the terminal device 20 and a young person (or an associate member), may be formed, but even if such a group is created, Use is prohibited by the management unit 127, that is, a configuration in which a message between users of the group cannot be transmitted / viewed.
And even if it is the said group, when the number of persons who comprise the said group will become three or more by the supplement of a member, it should just be set as the structure which permits the management part 127 to use the said group.

<Mail recipient>
In the above-described embodiment, the present invention is applied to a system in which a transmitted message is browsed between users of a group, but the present invention is not limited to this. In short, in a system that sends a message in a group consisting of a plurality of people, the number of users who make up the group is three or more, or even a system that does not include young people even if there are two people. Applicable. For this reason, for example, the present invention can be applied to a configuration in which mail is sent to a plurality of people who make up a group using a mailing list, or a configuration in which a mail is sent to a plurality of people by individually specifying a destination.

<Concept of youth>
In the above explanation, younger than 18 years old is a juvenile, but the concept of juveniles differs depending on the country, region, policy of the company that operates the SNS, etc. preferable.

<Consent to Group Registration>
When registering a user in a group, consent from the user may be a condition. That is, it may be conditional on receiving a notification from the user's terminal device 20 that he / she agrees to join the group. Here, when consent is used as a condition for registration with the group, consideration must be given to cases where consent for participation cannot be obtained afterwards. In particular, this is the case, for example, after the confirmation email for joining the group is sent to three people other than the self, and the two people do not agree. When the remaining one agrees and one of them is a juvenile, a group is composed of the self and the juvenile afterwards. This is because the message exchange becomes one.
In order to avoid this, when the number of users who have obtained consent is one or less than one of the young or associate members, for example, it is not possible to create a group, and when two or more users have obtained consent Thus, a configuration that enables creation of a group may be used.

<Message type>
In the above embodiment, three types of messages (A), (B), and (C) are used, but it goes without saying that other combinations may be used. For example, a photograph or video captured by a camera built in the terminal device 20, a photo or video stored in the terminal device 20, or position information may be included as a message.
Conversely, the message may be limited to those with an operation ID such as types (B) and (C). When limiting to those with action IDs, when no action ID is specified when sending a message, one of a plurality of action IDs prepared in advance is selected according to a predetermined rule (for example, random) The selected operation ID may be forcibly included in the message and transmitted. Further, a configuration may be adopted in which the user is warned that the operation ID is not designated and one of the operation IDs is included in the message to be transmitted.

<Native type>
In the embodiment, the display control unit 123 on the SNS server 10 side creates web screen information describing the display control and transmits it to the terminal device 20, while the browser 221 on the terminal device 20 side displays the web screen. At the same time, the process according to the operation on the web screen (touch panel) is executed. However, the present invention is not limited to this structure.
For example, a so-called native configuration in which the display screen of the display unit 211 is controlled by executing an application program installed in the terminal device 20 may be employed.

FIG. 22 is a functional block diagram showing a configuration of the system 1 according to the application example (part 1) of the native type, and shows functional blocks constructed when a message function (messenger) is executed.
As shown in this figure, on the terminal device 20 side, a display control unit 223, a reception unit 225, a specification unit 226, and a management unit 227 are constructed by executing an application program. The display control unit 223, the reception unit 225, the specification unit 226, and the management unit 227 are connected to the terminal device 20 with the display control unit 123, the reception unit 125, the specification unit 126, and the management unit 127 in the SNS server 10 in FIG. It has been moved.
In the configuration shown in FIG. 4, the display control unit 123 creates web screen information based on various information acquired from the touch operation or the database 108, transmits the web screen information to the terminal device 20, and displays the display unit via the browser 221. In the configuration shown in FIG. 22, the display control unit 223 directly displays the screen on the display unit 211 based on various types of information.
In the embodiment, when a large number of terminal devices 20 access the SNS server 10, the display control unit 123 needs to transmit a web screen to the large number of terminal devices 20. In the native configuration, the screen creation / control is distributed to each terminal device 20, so that the load can be reduced in that sense.

<Server / Client type>
As described above, regarding the display control unit, the reception unit, the specifying unit, and the management unit, it is arbitrary whether the display control unit, the specifying unit, and the management unit are built on the SNS server 10 side or the terminal device 20 side. The server 10 and the terminal device 20 may be separated.
FIG. 23 is a functional block diagram illustrating a configuration of the system 1 according to the server / client type application example (part 2). The reception unit 125, the identification unit 126, and the management unit 127 are configured in the SNS server 10, and display control is performed. An example in which the unit 223 is configured in the terminal device 20 is shown.
Eventually, either the terminal device 20 or the SNS server 10 may be provided for the display control unit, the reception unit, the specifying unit, and the management unit. The storage unit 106 may be managed by a configuration managed by a server other than the SNS server 10, that is, by cloud computing.
