Description

  The present invention relates to a display device, a control method, and a program.

  An application is provided in which a plurality of user terminals transmit and receive a message input in an e-mail, chat, or the like via a network such as the Internet. (For example, see Patent Document 1 as a chat application). When a user terminal having such an application receives a message, for example, the input message is associated with user information such as a user name identifying the user who has input the message, and the transmission date / time or reception date / time is set. Based on the time series, it is displayed so that the user can list it.

Japanese Patent No. 4782822

  In the application as described above, the user name associated with the message is not used as identification information (user ID) for uniquely identifying the user, but can be set to an arbitrary name by the user. For example, there is one in which user names of a plurality of users who send and receive messages to each other can be set to arbitrary names for each user terminal. In this case, for each user terminal, each user name can be set to an arbitrary name by the user who uses the terminal, and thus there is an advantage that the displayed user name is easy for the user to understand.

  However, when user names of a plurality of users who send and receive messages to each other are set to arbitrary names for each user terminal, the user names cannot be matched between the user terminals. Therefore, for example, in a user terminal that has received a message including a user name set in a partner user terminal, a message including an unknown user name that is not set may be displayed, which may impair convenience. There was a problem.

  The present invention has been made in view of such circumstances, and provides a display device, a control method, and a program capable of displaying a message with improved convenience.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
<First Embodiment>
FIG. 1 is a schematic block diagram showing a configuration of a chat system 1 according to the first embodiment of the present invention. The chat system 1 includes a plurality of user terminals 100-N (N is a positive integer. User terminal 100-1, user terminal 100-2, user terminal 100-3,...) And a server device 200. These computer devices are connected via a network 5. Here, since the plurality of user terminals 100-N have the same configuration, the description of “−1”, “−2”, etc. will be omitted and described as the user terminal 100 unless otherwise distinguished. Here, the three user terminals 100 are explicitly described, but the chat system 1 may include two or four or more user terminals 100.

  The user terminal 100 is a computer device used by a user, and is a display device that displays messages transmitted to and received from other user terminals 100 via the server device 200. As the user terminal 100, for example, an apparatus that includes a display device and can be connected to an information communication network, such as a PC (Personal Computer), a tablet PC, a smartphone, and a game machine, can be applied. Here, the user terminal 100 will be described as a smartphone. The network 5 is an information communication network configured by the Internet, a WAN (Wide Area Network), a LAN (Local Area Network), a dedicated line, or a combination thereof.

  The chat system 1 transmits and receives messages between the user terminals 100 of a plurality of users in a group in which a plurality of users are registered for chatting (that is, a group for performing group chat). Support limited communication among users within the company. As the chat system 1, for example, a computer system that transmits and receives messages associated with date and time information among the user terminals 100 of a plurality of users in a group by a chat application and displays them in chronological order based on the date and time information is applied. it can. In the present embodiment, an example in which the user terminal 100 displays a plurality of messages transmitted and received by the chat application will be described. Here, the user ID (Identifier) that identifies the user of the user terminal 100-1 is user A, the user ID that identifies the user of the user terminal 100-2 is user B, and the user of the user terminal 100-3 is identified. The user ID will be described as user C. It is assumed that user A, user B, and user C are registered in the same group for group chat.

  First, an outline of message transmission / reception processing in chat will be described. When chatting between a plurality of users in a group, the user terminal 100 (own device) sends a message sent to another user terminal 100 in response to an operation from the own user (first user) that is the user. And a message transmitted from the user terminal 100 (another device) of another user (second user) who is the other user. The user terminal 100 generates screen information (message screen) in which a plurality of stored messages are arranged in time series based on the date and time when the message is transmitted or received, and displays the screen information so that the user can list it.

  In other words, a self user (first user) who uses the user terminal 100 (own device) and one or more other users (second user) who use the user terminal 100 (other device) are registered in the group. ing. In this group, the user terminal 100 (own device) sends a message (first message) transmitted from the user terminal 100 (own device) in response to the operation of the own user (first user) and another user (second user). A message screen in which a message (second message) transmitted from the user terminal 100 (another device) in response to the operation of the user is arranged in time series is displayed.

FIG. 2 is a flowchart showing an example of a basic operation of message transmission / reception in the chat system 1. In FIG. 2, an example of processing in which the user terminal 100-1 of the user A and the user terminal 100-3 of the user C receive the message M transmitted by the user terminal 100-2 in response to an operation from the user B. Is shown.
First, in the user terminal 100-2, the user B inputs text as a message to be transmitted (step S100). Therefore, the user terminal 100-2 stores the message M input (created) according to the operation from the user B and displays it on the message screen (step S110). Here, the message M is associated with a user ID and a group ID. Here, the group ID is information for uniquely identifying the group, and is information indicating the destination of the message M. Subsequently, the user terminal 100-2 transmits the message M to the server device 200 (step S120).

Next, the server device 200 receives the message M from the user terminal 100-2 via the network 5, and temporarily stores the received message M (step S130). At this time, the server device 200 returns the reception date and time when the message M is received to the user terminal 100-2 together with the reception completion notification, and the date and time information when the message M is transmitted from the user terminal 100-2. (Referred to as transmission date / time information). The user terminal 100-2 that has received the reception completion notification acquires the transmission date and time information included in the reception completion notification and associates it with the message M. Also, the user terminal 100-2 displays the transmission date and time in association with the message M already displayed on the message screen (step S135).
Subsequently, the server device 200 receives and stores the received message M based on the group ID. The user terminal 100 of the user registered in the group (the user terminal 100-1 of the user A and the user terminal 100 of the user C). -3) (step S140). Next, the user terminal 100-1 receives the message M transmitted from the server device 200 via the network 5 (step S150). Further, the user terminal 100-3 receives the message M transmitted from the server device 200 via the network 5 (step S170). Each message M received is associated with transmission date and time information (reception time at the server device), user ID (user B), and group ID.

  Subsequently, the user terminal 100-1 stores the received message M and arranges the messages M in time series on the message screen based on the associated transmission date and time information (step S160). In addition, the user terminal 100-3 stores the received message M, and displays the message M in time series in accordance with the transmission date and time information associated with the message M (step S180). At this time, if the message cannot be displayed on one screen, the user terminal 100 displays a part of the messages arranged in time series and performs scroll control of the message. Here, the user terminal 100-1 and the user terminal 100-3 indicate the user who transmitted the message M based on the user ID associated with the message M when displaying the message M in time series. Information is displayed in association with the message M. In addition, the user terminal 100-1 and the user terminal 100-3 do not display the information indicating the own user who transmitted the message in association with the message transmitted by the own user, but display the message transmitted by another user. Only information indicating another user who has transmitted the message may be displayed in association with each other.

  As described above, in the chat system 1, messages are transmitted and received between the user terminals 100 of a plurality of users in the group, and a message screen in which the transmitted and received messages are arranged in time series is displayed on the user terminal 100. Thereby, in the chat system 1, the chat (group chat) which transmits / receives a message in the group to which a some user (chat partner) belongs can be performed. That is, messages transmitted (posted) by users participating in the group chat are displayed in a message screen arranged in time series based on the transmission time (posting time).

  Here, in order to clarify the problem to be solved by the chat system 1 of the present embodiment, a group chat in a general chat application will be described. In general group chat, users (chat members) in a group can freely send messages at any timing. Therefore, even if an attempt is made to send a response message (response message) to a message sent from a user in the group, if a message is sent from another user in the group before the reply message is sent, It may be difficult to know which user in the group the response message sent to. Therefore, when creating a response message, the reply destination “> Mr. XX” or “To Ms. XX” is included in the message text (for example, at the top) so that it can be understood which user's message is the response. There is a way to add as a text. In addition, when you select the message balloon of the other party you want to reply displayed on the message screen or the user information of the message (for example, select by tapping), it is automatically entered in the input field (text box) for entering the text as the message It may be possible to input the text “> Mr. OO”.

  By the way, in order to use a chat application, it is necessary to register user information (profile information) indicating a user who uses the chat application. The user information includes “user name (name)”, “profile image”, and the like. Here, the “user name” is not used as identification information for uniquely identifying the user, but is used as a so-called screen name (display name) to specify the sender of the displayed message. It is what This “user name” can be changed during use of the chat application.

However, a nickname that makes it difficult to identify the person is often used as the “user name”. When such a nickname is used, it becomes difficult for another user (chat partner) to specify which user the partner of the nickname is. Therefore, in the chat application, instead of the user name registered for each user in the group to use the chat application, a function is provided that allows the user name of the chat partner to be registered independently in the user terminal of the user. There is something that is. With this function, even if the user name registered by the user who is the chat partner is difficult to understand, or even if the user name registered by the user who is the chat partner is changed during the process, the user name that is set independently Is displayed with priority, making it easier to identify the chat partner user. It should be noted that the user name of the chat partner that the user originally registered is unknown to other users. In addition, when the unique user name is not registered, the user name registered by the chat partner user is used as it is.
In the chat application equipped with the function for registering the chat partner user name in this way, the user name of the chat partner registered by the user is preferentially used, so that it is displayed on each user terminal of the chat partner user. In the message screen, even if the message is posted (sent) by the same person, a different user name is displayed between the message screens. In a chat application that does not include this function, the same user name is displayed in messages posted by the same person on the message screen of each chat partner user.

  Therefore, when creating the above-mentioned response message, it is effective to add a user name as a response destination in the text of the message so that it can be understood which response is to which user. However, in the chat application equipped with the function that allows the user name of the chat partner to be uniquely registered, the user name that is uniquely registered is displayed with priority, so a reply is displayed in the message text displayed on the message screen. There is a problem that the user name added as the destination is different from the user name of the chat partner registered originally, and the user name may not be matched.

  Therefore, in order to solve the above problem, in the chat system 1 of the present embodiment, the user terminal 100 is configured as follows. First, the user terminal 100 is equipped with a function capable of independently registering the user name of another user (chat partner), and the user name of the other user (chat partner) registered independently is used as the user of the other user (chat partner). Registration is performed in association with identification information (user ID) that is uniquely identified. Further, when the received message (response message) is associated with the user ID of the response destination user (third user) that is the response destination of the message, the user terminal 100 uniquely corresponds to the user ID. The registered user name is displayed on the message screen as the information indicating the reply destination user. Thereby, the user terminal 100 can match the user name as a reply destination of the message (response message) displayed on the message screen with the user name of the other user (chat partner).

Here, with reference to FIG. 3 to FIG. 5, first, a function capable of uniquely registering the user name of another user (chat partner) will be described.
FIG. 3 is a diagram illustrating an example of a message screen before the user names of other users are independently registered. Reference numeral 110a indicates the entire area where the message screen is displayed. This message screen displays a part of a plurality of transmitted and received messages. The user terminal 100 can display a message that cannot be displayed in one screen by scrolling the message up and down in response to a scroll operation performed at an arbitrary position on the screen that is a touch panel, for example.

  In this FIG. 3, the example of the message screen of the chat (group chat) by the user A, the user B, and the user C which the user terminal 100-1 of the user A displays is shown. The unit of users who chat is called a group. This message screen is a chat message screen of a group to which three people, user A, user B, and user C, belong. User A is user A, and other users (chat partners) are user B and user C. In the area 110b, the name of the group in the group chat is displayed. Here, an example is shown in which “company” is set as the name of the group to which three users A, B, and C belong, and the set group name is displayed.

  In the area 110c, there is a display component so that messages sent from users in the group are displayed in ascending order (new messages below the area 110c) based on the date and time that the message was sent. Be placed. The date on which the message is transmitted is displayed on the date label E1. When there are a plurality of messages with the same date, the date label E1 is displayed above the message associated with the transmission date / time information indicating the oldest date / time among the plurality of messages. That is, the message is displayed by being separated by the date label E1 for each date. The icon E3 is an icon indicating another user. The icon E3 may be, for example, an image (for example, a profile image) registered in advance by another user or an image prepared in advance by the chat system 1. The user name label E4 displays the user name of the user corresponding to the icon E3. Here, the user name registered in the user terminal 100-2 of the user B is “Yamada B man”, and the user name of the user B is displayed.

  In the balloon E5, a message transmitted from another user (here, user B) and a transmission time (transmission time) are displayed. This transmission time is the time when the message displayed in the balloon E5 is transmitted from another user (here, user B), and is the transmission time based on the transmission date information associated with this message. In the example shown in this figure, the message of another user (user B or user C) is displayed in a balloon from the left side of the message screen. The message of the user (user A) is displayed in a balloon from the right side of the message screen, but is omitted in this figure (the message of the user is not on the message screen).

  FIG. 4 is a diagram for explaining a method of uniquely registering the user name of another user (chat partner). Here, the screens displayed on display unit 110 of user terminal 100-1 of user A according to the registration procedure are shown in the order of reference ST1, reference ST2, reference ST3, and reference ST4. The screen indicated by reference sign ST1 is a screen on which user information (profile information) of another user (here, user B) is displayed. In the screen indicated by reference numeral ST1, in the area indicated by reference numeral 110f in the screen area indicated by reference numeral 110a, a name (here, “profile”) indicating that this screen is a screen displaying user information (profile information), A “return” button F1 is displayed. The “return” button F1 switches (returns) to the previously displayed screen in accordance with a user operation. In the area denoted by reference numeral 110g, a display component is arranged so that user information of the user (here, user B) selected in accordance with the user's operation is displayed. The icon F2 is an icon (for example, a profile image) shown by the user B. The user name of user B is displayed on the user name label F3. Here, “Yamada B man”, which is the user name of user B registered in user terminal 100-2 of user B, is displayed. In the following description, the user name registered in the user terminal 100 of the user is also referred to as “basic user name”. When a tap operation is performed on the icon F2 or the user name label F3 on the screen indicated by the symbol ST1, the screen shifts to a screen where the user name indicated by the symbol ST2 can be edited.

  In the screen denoted by reference numeral ST2, in the area denoted by reference numeral 110f, a name (in this case, “edit user name”) indicating that this screen is an editable user name, a “cancel” button F4, and “ The “Finish” button F5 is displayed. The “Cancel” button F4 switches (returns) to the screen indicated by the symbol ST1 without editing the user name in accordance with the user operation. The “complete” button F5 completes the editing of the user name in accordance with the user operation, and switches to the screen indicated by the symbol ST1 (returns). A text box F6 for inputting text as a user name is displayed in the area 110h. In the text box F6, the basic user name of the currently registered user B (“Yamada B man”) is entered. A software keyboard F7 for inputting or correcting text in the text box F6 is displayed in the area denoted by reference numeral 110k. When the text as the user name input in the text box F6 is edited in response to an operation on the software keyboard F7 on the screen indicated by the symbol ST2, the screen indicated by the symbol ST3 is displayed.

  The screen indicated by the symbol ST3 is different from the screen indicated by the symbol ST2 only in the text as the user name input in the text box F6. Here, in the text box F6, the user name (“company boss”) edited according to the operation on the software keyboard F7 is displayed. Here, the user name ("company manager") edited on the screen indicated by reference ST2 is the user name of user B registered uniquely in user terminal 100-1 of user A. In the following description, the user name of another user uniquely registered in the user terminal 100 of the user is also referred to as “unique user name”. When a tap operation is performed on the “complete” button F5 on the screen indicated by the symbol ST3, the editing of the user name is completed, and the screen shifts to the screen indicated by the symbol ST4.

  The screen indicated by symbol ST4 is different from the screen indicated by symbol ST1 only in the user name displayed on the user name label F3. That is, in the screen indicated by the reference ST1, the user name label F3 displays the basic user name of the user B (“Yamada B male”). However, in the screen indicated by the reference ST4 after editing, the user name label F3 is displayed. Displays the unique user name of user B ("boss of the company"). Thus, in the user terminal 100, the user name of the chat partner can be uniquely registered as a unique user name. When this unique user name is registered in the user terminal 100, the unique user name is used instead of the basic user name.

  FIG. 5 is a diagram illustrating an example of a message screen after the user names of other users are registered uniquely. In FIG. 5, parts corresponding to those shown in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. In FIG. 3, the basic user name of user B (“Yamada B male”) is displayed in the user name label E4. In FIG. 5, the user B uniquely registered in the user terminal 100-1 of user A is displayed. The unique user name (“company manager”) is displayed.

  As described above, in the chat system 1 of the present embodiment, the user terminal 100 uniquely registers the user name (the user name of the other user who transmitted the message) displayed in association with the message. Can be displayed. This unique user name is used in the user terminal 100 of the registered user and is a user name that is not known to other users. Therefore, if a user transmits a message including a unique user name as a user name of a reply destination user (hereinafter also referred to as a reply destination user name), the user terminal 100 of another user who has received the message The response destination user name that is unknown to other users who have received is displayed. Therefore, in the chat system 1 of the present embodiment, the user terminal 100 sends a reply destination user ID (hereinafter also referred to as a reply destination user ID) in association with a message instead of the reply destination user name. In addition, when a response destination user ID is associated with the received message, the user terminal 100 has a unique user name registered in the user terminal 100 that has received the message, and is unique to the response destination user ID. The user name is displayed on the message screen in association with the message. Thereby, the user terminal 100 can match the user name of the other user who transmitted the message and the response destination user name displayed on the message screen.

Hereinafter, the configuration of the chat system 1 according to the present embodiment will be described in detail.
First, the configuration of the user terminal 100 will be described with reference to FIG.

The storage unit 140 includes a user information storage unit 141, a group information storage unit 142, a message information storage unit 143, and a screen information storage unit 144.

  The user information storage unit 141 stores user information related to a user who performs chat. 7 and 8 are diagrams illustrating examples of user information stored in the user information storage unit 141. FIG. The user information includes information in which a user ID is associated with a user name. The user ID is information for identifying the user. The user name is the name of the user. Although not shown in this figure, the user information may further store a user image in association with the user ID and the user name. A user image is a profile image of the user. Specifically, information for identifying user image data is associated with a user ID and a user name, and the user information storage unit 141 stores the associated user information and actual data of the user image. Are stored respectively. As the user image, an image arbitrarily registered by the user can be applied, but a common image set in advance is applied when not registered.

  Here, the user information shown in FIG. 7 is an example of the user information of the own user, and is an example of the user information of the user A stored in the user terminal 100-1 of the user A. Further, the user information shown in FIG. 8 is an example of user information of other users that can be registered as chat partners, and the user information of other users stored in the user terminal 100-1 of user A (user of user B) Information and user information including user information of user C). The user names included in the user information of other users shown in FIG. 8 include a basic user name and a unique user name. The basic user name is registered by the user himself / herself in each user terminal 100-N. The user ID and basic user name of another user stored in the user terminal 100-1 of the user A shown in FIG. 8 are registered as a chat partner when a user relationship that can be registered as a chat partner is established. Acquired from the user terminal 100-N of each other user and stored. In this figure, “Yamada B man” is stored as the basic user name of the user B, and “Takahashi C child” is stored as the basic user name of the user C. On the other hand, the unique user name is a user name of another user (a user name including the user name of user B and the user name of user C) registered by user A in the user terminal 100-1 of user A. In this figure, “company boss” is stored as the unique user name of the user B, and “company subordinate” is stored as the unique user name of the user C.

  The group information storage unit 142 stores information related to a group of users who perform chat. FIG. 9 is a diagram illustrating an example of group information stored in the group information storage unit 142. Two or more users belong to one group. For example, when the user A and the user B chat, group information regarding the group to which the user A and the user B belong is stored in the group information storage unit 142. The group information includes information in which a group ID, a group name, and a user ID are associated with each other. The group ID is information that uniquely identifies a group generated by the server device 200. The group name is a name of the group and is automatically given when the group is formed, and can be set by the user afterwards. The user ID is information for identifying users belonging to the group. Here, for example, the name of the group whose group ID is “G1” is set as “company” by the user. It is shown that the users belonging to this group are three users of “user A”, “user B”, and “user C”. The name of the group whose group ID is “G2” is not set by the user. In a chat (one-to-one chat) in which two people belong like a G2 group, the user information storage unit 141 is referred to, and the user name of the chat partner (here, “Yamada B man”) is automatically used as the group name. Is set. It is indicated that two users, “user A” and “user B”, belong to the G1 group.

  The message information storage unit 143 stores message information related to a message transmitted / received in a group to which the user belongs, or message information related to a message input from the user terminal 100 as a draft message. The message information includes information in which a group ID, a user ID, transmission date / time information, and a message are associated with each other. The group ID is information for identifying a group in which a message is transmitted / received. The user ID is information for identifying the user who has input the message. The transmission date / time information is information indicating the date / time when the message was transmitted. In the present embodiment, messages transmitted from each other between users having different time information indicated by the time counting function of the user terminal 100 or between users in an area having a time difference are transmitted from the user terminal 100 so that they are correctly arranged in time series. The reception time when the message is received by the server device 200 is used as transmission date and time information indicating the date and time when the message is transmitted. Here, the transmission date / time information includes year, month, day, hour, minute, second (YYYY / MM / DD HH: MM: SS) information. The message is a character string (text) indicating a message transmitted / received to / from another user or a draft message input by the user.

Returning to FIG. 6, the screen information storage unit 144 temporarily stores screen information of a message screen that displays a plurality of messages as described above in time series.
The control unit 150 includes an information processing apparatus such as a CPU (Central Processing Unit) that functions as a control center of the user terminal 100, and controls each unit included in the user terminal 100. The control unit 150 includes a message transmission instruction unit 151, a message transmission unit 152, a message reception unit 153, an acquisition unit 155, a registration unit 156, a management unit 157, and a display control unit 158.

  The message transmission instruction unit 151 generates transmission instruction information indicating a message transmission instruction in chat based on an input instruction generated by the operation reception unit 120 in response to a user operation on the operation reception unit 120. Specifically, when a message is input by the user and an operation for transmitting the input message is performed on the message screen, the message transmission instruction unit 151 receives the message in which the message is input. Transmission instruction information including message information in which a group ID that identifies a chat group on the screen and a user ID that identifies a user who has input a message is associated is generated. When the user performs an operation of selecting a reply destination user for the message to be transmitted, the message transmission instruction unit 151 further adds a user ID for identifying the reply destination user to the input message. Transmission instruction information including the associated message information is generated.

  When the message transmission instruction unit 151 generates transmission instruction information in response to an operation on the operation reception unit 120, the message transmission unit 152 reads the group ID of the message screen on which the message is input from the group information storage unit 142. Then, the message transmission unit 152 transmits the message information included in the transmission instruction information generated by the message transmission instruction unit 151 to the server device 200 with the read group ID as a destination. Specifically, the message transmission unit 152 transmits the input message in association with the group ID and the user ID (own user). When a response destination user (third user) is selected, the message transmission unit 152 associates the input message with a group ID and a user ID (own user), and further corresponds with a response destination user ID. Send with attachment. That is, the message transmission unit 152 does not transmit the information indicating the response destination user in the message as text, but transmits the message in association with the response destination user ID. At this time, the message transmission unit 152 stores the group ID, the user ID (own user), and the message or the response destination user ID included in the message information in the message information storage unit 143 as a new record. The transmission date / time information updates the transmission date / time information of the record of the corresponding message using the reception date / time information acquired together with the reception completion notification from the server device 200 as the transmission date / time information.

  The message receiving unit 153 receives message information transmitted from the user terminal 100 of another user. Specifically, the message receiving unit 153 receives, from the server device 200, message information transmitted from another user terminal 100 with the group ID of the group to which the user belongs to the group ID included in the message information. , User ID (other users), transmission date and time information, and message or reply destination user ID are stored in the message information storage unit 143 as a new record.

  The acquisition unit 155 associates a basic user name (second second user information) as information indicating another user, set by each of a plurality of other users (second users), with the user ID of each other user. Acquire it. Here, the acquisition unit 155, for example, from another user terminal 100 of each other user when the other user becomes a user relationship that can be registered in the group as a chat partner or when the other user is registered in the group as a chat partner. The user ID and basic user name of the user are acquired. In addition, the acquisition unit 155 associates the acquired user IDs of other users with the basic user name and stores them in the user information storage unit 141 via the management unit 157. Here, as illustrated in FIG. 8, the acquisition unit 155 obtains “Yamada B male” who is the basic user name of the acquired user B and “Takahashi C child” which is the basic user name of the acquired user C. The information is stored in the user information storage unit 141.

  The registration unit 156 registers a unique user name (first second user information) as information indicating another user (second user) in association with the user ID of the other user. For example, the registration unit 156 registers a unique user name (first second user information) based on information input by the own user (first user). Here, the information input by the own user is information indicating the user name of another user input by the own user in the user terminal 100 of the own user. For example, in response to an operation according to the operation procedure described with reference to FIG. 4, the registration unit 156 registers the unique user name of another user. In addition, the registration unit 156 associates the user ID of the other user to be registered with the unique user name, and stores them in the user information storage unit 141 via the management unit 157. Here, as illustrated in FIG. 8, the registration unit 156 stores the user B's unique user name as “company supervisor” and the user C's unique user name as “company subordinate” in the user information storage unit 141. Let

  The management unit 157 includes the unique user name (first second user information) of the other user registered by the registration unit 156, the basic user name (second second user information) of the other user acquired by the acquisition unit 155, and Are managed in association with user IDs of other users. Specifically, the unique user name of the other user and the basic user name of the other user are associated with the user ID of the other user and stored in the user information storage unit 141 for management.

  The management unit 157 may be configured as the user information storage unit 141. In that case, the user information storage unit 141 may manage the unique user name of the other user and the basic user name of the other user in association with the user ID of the other user as the management unit 157. The user information storage unit 141 may be provided in an external storage device (for example, a chat server or a cloud server) connected to the user terminal 100 via the network 5. In that case, the management unit 157 causes the user information storage unit 141 included in the external storage device to store the unique user name of the other user and the basic user name of the other user in association with the user ID of the other user. May be managed.

  The display control unit 158 performs a message (first message) transmitted from the user terminal 100 (own device) in response to an operation of the own user (first user) and an operation of one or more other users (second user). In response, messages (second messages) transmitted from other user terminals 100 (other devices) are displayed in time series on the display unit 110. Further, the display control unit 158 displays information indicating another user who has transmitted the message in association with a message transmitted from another user terminal 100 (another device) (see FIG. 5). Specifically, the display control unit 158 reads a plurality of message information stored in the message information storage unit 143, and converts the messages included in each of the read plurality of message information into date and time information associated with each of them. Based on this, screen information of message screens arranged in time series is generated and stored in the screen information storage unit 144. Then, the display control unit 158 causes the display unit 110 to display a part of the generated screen information.

  Further, the display control unit 158, for a message included in message information transmitted from another user terminal 100 (another device), based on a user ID (another user) associated with the message, The unique user name (for example, refer to the user name label E4 in FIG. 5) and the profile image of the other user associated with the user ID stored in the information storage unit 141 and the profile image are displayed in association with each other.

  Here, it is assumed that the message transmitted by the message transmission unit 152 is associated with the user ID of the reply destination user (third user) selected as the reply partner. In this case, the display control unit 158 displays the unique user name (first second user information) corresponding to the user ID on the display unit 110 as information indicating the reply destination user in association with the message to be transmitted. Let Also, a message received by the message receiving unit 153 (a message transmitted from another user terminal 100 (another device)) is selected as a reply partner from a plurality of other users (second users) registered in the group. It is assumed that the user ID of the response destination user (third user) is associated. In this case, the display control unit 158 displays the unique user name (first second user information) corresponding to the user ID on the display unit 110 in association with the received message as information indicating the reply destination user. Let A display example in which such a unique user name is displayed on the message screen as information indicating the reply destination user will be described later with reference to FIGS.

  The display control unit 158 displays the unique user name on the display unit 110 in association with a message as information indicating the reply destination user, and then displays the unique user name using the registration unit 156 according to the operation of the own user (first user). When the user name is changed, the information indicating the response destination user to be displayed is replaced with the changed unique user name.

  Here, the display control unit 158 causes the display unit 110 to display a part of the generated screen information. For example, the display control unit 158 causes the display unit 110 to display a part including the message specified by the operation from the user in the screen information. Part of the screen information to be displayed on the display unit 110 in the initial stage may be, for example, a location including a message (latest message) associated with the latest transmission date and time information among a plurality of read messages. it can.

Note that the plurality of message information described above may include message information associated with the same transmission date and time information (that is, message information with the same transmission date and time). In this case, the display control unit 158 may display the message information associated with the same transmission date and time information on the message screen in time series according to the order stored in the message information storage unit 143, for example. Good. When the message receiving unit 153 receives message information associated with the same transmission date / time information, the transmission date / time information different from each other is counted by counting up the time (for example, the number of seconds) of one transmission date / time information. May be stored.
In the plurality of message information described above, the plurality of message information described above may be configured not to include message information associated with the same transmission date and time information. In this case, the server apparatus 200 may prohibit associating message information with the same transmission date / time information, and may associate different transmission date / time information with each message information. Specifically, when the server apparatus 200 receives message information that has the same transmission date and time information, the server apparatus 200 may count up the time (for example, the number of seconds) of one transmission date and time information.

Next, the configuration of the server device 200 will be described with reference to FIG. FIG. 10 is a schematic block diagram showing the configuration of the server device 200 according to the present embodiment.

In addition, the user information storage unit 141 and the group information storage unit 142 included in the user terminal 100 include information related to the user himself (user's own user information and other users who can be registered in the same group as the user himself / herself). Only user information) is stored. On the other hand, the user information storage unit 241 and the group information storage unit 242 included in the server device 200 store information about all users and groups that transmit and receive messages via the server device 200. Note that the user information storage unit 241 included in the server device 200 does not store information such as a user name or a user image that identifies the user, but stores a user ID that can simply identify the user. It is good.

  The server storage unit 240 includes a message information temporary storage unit 243. The message information temporary storage unit 243 temporarily stores message information received from each user terminal 100. For example, the message information temporary storage unit 243 temporarily stores the received message information until the received message information is transmitted to the user terminal 100 of the destination (transmission destination) user.

The server control unit 250 includes a message transfer unit 251.
When the message transfer unit 251 receives the message information transmitted from the user terminal 100 with the group ID as the destination, the message transfer unit 251 temporarily stores the received message information in the message information temporary storage unit 243. Then, the message transfer unit 251 specifies the user ID associated with the group ID that is the destination of the received message information, and stores the stored message information in the message of the user terminal 100 indicated by the specified user ID. Is transmitted to the user terminal 100 other than the user terminal 100 indicated by the user ID of the user who transmitted the message. Note that the message transfer unit 251 may transmit this message information to a user terminal 100 other than the user terminal 100 indicated by the user ID of the user who sent the message among the user terminals 100 indicated by the specified user ID. . That is, the message transfer unit 251 transfers a message transmitted by a user in the group to another user in the group.

  When the message transfer unit 251 receives the message information transmitted from the user terminal 100 with the group ID as the destination, the message transfer unit 251 transmits the reception date and time when received to the user terminal 100 together with the reception completion notification.

Next, with reference to the drawings, in the user terminal 100 of the present embodiment, a process of selecting a response destination user and transmitting a message and information (user name) indicating the response destination user are displayed in association with the message. The processing will be described in detail.

Also, below the balloon E17, a balloon E18 (a balloon from the right side) displaying the message transmitted by the user C who is the user and the transmission date and time is displayed.

Further, below the balloon E18, a message transmitted from the user terminal 100-1 (user A) with the user B as the reply destination user is displayed. Here, since this message is a message transmitted by another user (user A), it is displayed in a balloon E22 from the left side. In the balloon E22, the message transmitted with the user B as the reply destination user and the transmission time are displayed. In addition, a response destination user name label E21, a user name label E20, and an icon E19 are displayed in association with the balloon E22. In the reply destination user name label E21, information indicating a reply (here, “RE:”) and a reply destination user name (here, user B's unique user name “Mr. Yamada”) are displayed. The user name label E20 displays the unique user name of user A (here, “Mr. Tanaka”). The icon E19 is an icon (for example, a profile image of the user A) indicating the user A who has transmitted this message.
In addition, it is good also as a structure by which the icon (for example, user B's profile image) which shows a reply destination user is displayed corresponding to the speech balloon E22.

  In this way, in the user terminal 100-3 of the user (here, user C) who has received the message sent by another user (here, user A) selecting the reply destination user from the user terminal 100-1, the reply destination user Is displayed on the display unit 110 in association with information indicating the reply destination user. Therefore, since the user receives a unique user name as a response destination user name in response to a message received from another user, the user can easily determine which user the message to be transmitted is a reply to. Can be determined.

Next, an operation example of the chat system 1 according to the present embodiment will be described with reference to the drawings.
(Description of display processing operation)
First, with reference to FIG. 15, an operation of processing for displaying information indicating a response destination user in association with a message according to whether or not a response destination user ID is associated with the received message will be described. FIG. 15 is a flowchart illustrating an example of display processing for displaying a message received by the user terminal 100.

  The message reception unit 153 receives message information transmitted from the user terminal 100 of another user from the server device 200 via the network 5. Then, the message reception unit 153 stores the message information received from the server device 200 in the message information storage unit 143 as a new record (step S210).

  Next, the display control unit 158 determines whether or not the response destination user ID is included in the message information stored in the message information storage unit 143. For example, when the display control unit 158 displays the message information stored in the message information storage unit 143 in chronological order on the display unit 110, the response destination user ID is included in each message information read from the message information storage unit 143. It is determined whether it is included (step S220).

  If it is determined in step S220 that the response destination user ID is included (step S220: YES), the display control unit 158 displays the unique user associated with the response destination user ID included in the message information. The name is read from the user information storage unit 141, and the read unique user name is displayed on the display unit 110 as a response destination user name. Here, the display control unit 158 displays the reply destination user name at a predetermined position associated with the position where the message included in the message information is displayed on the message screen (step S230). On the other hand, when it is determined in step S220 that the reply destination user ID is not included (step S220: NO), the display control unit 158 advances the process to step S240 without performing the process of step S230.

  Subsequently, the display control unit 158 arranges the messages included in each message information read from the message information storage unit 143 in step S210 in time series on the display unit 110 based on the transmission date information included in each message information. It is displayed (step S240).

  In addition, although the process which displays the information which shows a reply destination user in association with the received message was demonstrated using FIG. 15, the process which displays the information which shows a reply destination user in association with the message to transmit is also the same. Done. For example, the display control unit 158 determines whether or not the response destination user ID is included in the message information of the message to be transmitted, and the message including the response destination user ID is unique to the response destination user ID. The user name is displayed in association with the display unit 110.

(Explanation of transmission processing operation)
Next, with reference to FIG. 16, an operation of processing for transmitting a message in association with a response destination user ID according to whether or not a response destination user has been selected will be described. FIG. 16 is a flowchart illustrating an example of a transmission process in which the user terminal 100 transmits a message.

  First, the user inputs text as a message to be transmitted by an operation on a message screen displayed on the display unit 110 (step S310). The operation reception unit 120 receives an instruction to input a message in response to an operation from the user. At this time, it is assumed that the user performs an operation of selecting a reply destination user and inputting a message. In that case, for example, the operation receiving unit 120 receives an instruction to select a reply destination user and an instruction to input a message to be transmitted in response to the operation on the message screen shown in FIG. In addition, the operation reception unit 120 generates an input instruction according to the received instruction content.

  Next, the message transmission instruction unit 151 generates transmission instruction information indicating a message transmission instruction in chat based on an input instruction generated by the operation reception unit 120 in response to a user operation on the operation reception unit 120. Here, the message transmission instruction unit 151 determines whether or not the input message is a message for which a reply destination user has been selected based on the input instruction generated by the operation reception unit 120 (step S320). . When it is determined in step S320 that the reply destination user is the selected message (step S320: YES), the message transmission instruction unit 151 associates the selected reply destination user ID with the input message. Transmission instruction information including the information is generated (step S330). On the other hand, when it is determined in step S320 that the message is a response destination user not selected (step S320: NO), the message transmission instruction unit 151 does not include the response destination user ID (set as invalid data). Transmission instruction information including information is generated.

  Subsequently, when the message transmission instruction unit 151 generates transmission instruction information in response to an operation on the operation reception unit 120, the message transmission unit 152 reads the group ID of the message screen on which the message is input from the group information storage unit 142. . Then, the message transmission unit 152 transmits the message information included in the transmission instruction information generated by the message transmission instruction unit 151 to the server device 200 with the read group ID as a destination. At this time, the message transmission unit 152 causes the message information storage unit 143 to store the group ID, the user ID (own user), and the message or the response destination user ID included in the message information as a new record (step S340). .

  As described above, the user terminal 100 according to the present embodiment includes the own user (first user) who uses the user terminal 100 (own device) and a plurality of other users who use other user terminals 100 (other devices). The message transmitted in the group in which the user (second user) is registered is displayed on the display unit 110 in time series, and the message is transmitted to a message transmitted from another user terminal 100 (another device). A display control unit 158 that displays the transmitted information indicating other users in association with each other is provided. Also, the user terminal 100 registers a unique user name (first second user information) as information indicating another user in association with identification information (user ID of the other user) that uniquely identifies the other user. A registration unit 156 and a message reception unit 153 that receives a message transmitted from another user terminal 100 (another device) are provided. In the message received by the message receiving unit 153, identification information (response destination) that uniquely identifies a response destination user (third user) selected as a response partner among a plurality of other users registered in the group. Assume that (user ID) is associated. In this case, the display control unit 158 uses the unique user name corresponding to the identification information (response destination user ID) among the unique user names registered by the registration unit 156 as information indicating the response destination user in the received message. The information is displayed on the display unit 110 in association with each other.

  That is, when the message received by the message receiving unit 153 is associated with the reply destination user ID selected as the reply partner, the display control unit 158 displays the received messages on the display unit 110 in time series. Let Also, the display control unit 158 causes the display unit 110 to display the unique user name corresponding to the response destination user ID as information indicating the response destination user in association with the received message.

  Thereby, the user terminal 100 can display information indicating the reply destination user selected as the reply partner in the received message using the unique user name uniquely registered in the user terminal 100 that has received the message. it can. Moreover, in order to display the information which shows the other user who transmitted the said message with respect to the received message using the unique user name uniquely registered in the user terminal 100 which received the said message, Both the information indicating the user (another user) who transmitted the received message and the information indicating the message reply destination user can be displayed using the unique user name. In this way, the user terminal 100 can match the user name as the reply destination of the message (response message) displayed on the message screen with the user name of the other user (chat partner). Therefore, the user can easily determine to which user in the group the message displayed on the message screen has been replied. That is, according to the user terminal 100 of the present embodiment, it is possible to display a message with improved convenience.

  In addition, the user terminal 100 can input a message to be transmitted from the user terminal 100 (own device) so that a response destination user (third user) can be selected from a plurality of other users (second user). (Input unit). Further, when a response destination user is selected in the operation reception unit 120, the user terminal 100 identifies the response destination user by identifying the message input to the operation reception unit 120 (response destination user ID). And a message transmission unit 152 that transmits the data in association with each other.

  Thereby, the user terminal 100 can select a reply destination user for the message to be transmitted. In addition, the user terminal 100 can transmit the message for which the response destination user is selected in association with the response destination user ID. Therefore, the user terminal 100 receives the user name registered in the received user terminal 100 (another device) in the user terminal 100 (another device) that has received the message for which the reply destination user has been selected (for example, the other device). The message can be transmitted in association with the user ID of the selected reply destination user so that the registered unique user name can be displayed.

  In the user terminal 100, identification information (response destination user ID) uniquely identifying the response destination user (third user) selected by the operation reception unit 120 (input unit) in the message transmitted by the message transmission unit 152. Assume that they are associated. In this case, the display control unit 158 displays the unique user name (first second user information) corresponding to the identification information (response destination user ID) among the unique user names registered by the registration unit 156 as the response destination user. Information to be displayed is displayed on the display unit 110 in association with the message to be transmitted.

  That is, when the reply destination user ID selected as the reply partner is associated with the message to be transmitted, the display control unit 158 displays the message to be transmitted in time series on the display unit 110 and displays the reply destination user ID. Is displayed on the display unit 110 in association with the message to be transmitted as information indicating the reply destination user.

  As a result, the user terminal 100 can display information indicating the reply destination user selected as a reply partner in the message to be transmitted using the unique user name uniquely registered in the user terminal 100. Moreover, since the user terminal 100 displays the information indicating the other user who transmitted the message using the unique user name uniquely registered in the user terminal 100, the received message is displayed. Both the information indicating the transmitted user (other users) and the information indicating the reply destination user of the message to be transmitted can be displayed using the unique user name. Therefore, the user terminal 100 can match the user name as a reply destination of the message (response message) displayed on the message screen with the user name of another user (chat partner).

In the user terminal 100, the registration unit 156 registers a unique user name (first second user information) based on information input by the own user (first user).
Thereby, the user terminal 100 can display the user name of another user using the unique user name input in response to an operation from the own user. That is, the user can display the user name of the chat partner with an arbitrary name on the user terminal 100.

  Thus, according to the present embodiment, it is possible to display a message with improved convenience.

  In the above embodiment, the process in which the user terminal 100 displays the unique user name uniquely registered as the user name of the other user as the information indicating the reply destination user has been described. This is based on the assumption that the response destination user is another user, but the response destination user may be the user itself. In this case, the response destination user ID associated with the message received by the user terminal 100 is the user ID of the own user, and the user terminal 100 uses the user name of the own user as information indicating the response destination user ( For example, in the user information of the own user shown in FIG. 7, the user name associated with the user ID of the own user may be displayed.

  In the above embodiment, the process of displaying the unique user name corresponding to the response destination user ID associated with the message as information indicating the response destination user has been described. Information other than the unique user name may be displayed as information indicating a response destination user. For example, when the unique user name is not registered, the user terminal 100 may display the basic user name of the response destination user as information indicating the response destination user. As described above, the process of displaying the unique user name or the basic user name depending on whether or not the unique user name is registered will be described in detail in a second embodiment to be described later.

  Further, when both the basic user name and the unique user name are not registered, the user terminal 100 may display the user ID or mail address of the response destination user as information indicating the response destination user. Good. In addition, the user terminal 100 can register a user image (for example, a profile image) corresponding to another user, and can display a unique user image uniquely registered in the user terminal 100 as information indicating a reply destination user. Good. Further, the user terminal 100 may display either one or both of a user name (unique user name or basic user name) and a user image as information indicating a response destination user.

(Modification)
In the above-described embodiment, the user terminal 100 may be configured to include at least the display control unit 158, the registration unit 156, and the message reception unit 153. For example, the user terminal 100 may be configured not to have a function of selecting a response destination user and transmitting a message. Note that the user terminal 100 may have a function of transmitting a message without selecting a response destination user, and adding a function of selecting a response destination user and transmitting a message as an optional function (for example, downloading an additional program) It may be possible to add a configuration that can be added.
Here, the display control unit 158 includes a local user (first user) who uses the user terminal 100 (own device), and a plurality of other users (second users) who use the other user terminal 100 (other device). Is displayed on the display unit 110 in chronological order on the messages transmitted in the group in which is registered, and for messages transmitted from other user terminals 100 (other devices), information indicating other users who transmitted the messages Are displayed in association with each other. The registration unit 156 registers a unique user name (first second user information) as information indicating another user in association with identification information (user ID of the other user) that uniquely identifies the other user. The message receiving unit 153 receives a message transmitted from another user terminal 100 (another device). In the message received by the message receiving unit 153, identification information (response destination) that uniquely identifies a response destination user (third user) selected as a response partner among a plurality of other users registered in the group. Assume that (user ID) is associated. In this case, the display control unit 158 uses the unique user name corresponding to the identification information (response destination user ID) among the unique user names registered by the registration unit 156 as information indicating the response destination user in the received message. The information is displayed on the display unit 110 in association with each other.
With this configuration, the user terminal 100 displays information indicating a reply destination user selected as a reply partner in the received message using a unique user name uniquely registered in the user terminal 100 that has received the message. Can do. Moreover, in order to display the information which shows the other user who transmitted the said message with respect to the received message using the unique user name uniquely registered in the user terminal 100 which received the said message, Both the information indicating the user (another user) who transmitted the received message and the information indicating the message reply destination user can be displayed using the unique user name. In this way, the user terminal 100 can match the user name as the reply destination of the message (response message) displayed on the message screen with the user name of the other user (chat partner). Therefore, the user can easily determine to which user in the group the message displayed on the message screen has been replied. That is, according to the user terminal 100 of the present embodiment, it is possible to display a message with improved convenience.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. Since the configuration of the chat system 1 of the present embodiment is the same as that of the first embodiment, a characteristic process in the present embodiment will be described. In the present embodiment, the user terminal 100 will be described with reference to a process of selecting a user name to be displayed as information indicating a response destination user depending on whether or not a unique user name is registered.

  As described above, the unique user name is a user name that is uniquely registered by each user terminal 100 using the user terminal 100. Assume that this unique user name is not registered in the user terminal 100. In this case, the user terminal 100 displays the user name of another user using the basic user name. Specifically, the display control unit 158 associates the message included in the received message information with the basic user name corresponding to the user ID (other user, message sender) included in the message information, and displays the display unit. 110 is displayed. Further, when the response destination user ID is associated with the received message, the display control unit 158 causes the display unit 110 to display the basic user name corresponding to the response destination user ID in association with each other.

  With reference to FIG. 17, an operation of processing for controlling information indicating a response destination user displayed in association with a received message according to whether or not a unique user name is registered will be described. FIG. 17 is a flowchart illustrating an example of display processing for displaying a message received by the user terminal 100 according to the present embodiment. In FIG. 17, processes corresponding to those in FIG. 15 are denoted by the same reference numerals, and description thereof is omitted as appropriate.

  First, similar to the processing described with reference to FIG. 15, the message receiving unit 153 receives message information transmitted from the user terminal 100 of another user (step S210), and the display control unit 158 receives the received message. It is determined whether or not the response destination user ID is included in the information (step S220).

  If it is determined in step S220 that the reply destination user ID is included (step S220: YES), the display control unit 158 determines whether or not the unique user name is registered by the registration unit 156 (step S220). S225). On the other hand, when it is determined in step S220 that the reply destination user ID is not included (step S220: NO), the display control unit 158 performs the process in step S240 without performing the processes in steps S225, S232, and S234. To proceed.

  When it is determined in step S225 that the unique user name is registered (step S225: YES), the display control unit 158 displays the unique user name associated with the reply destination user ID included in the message information. Is read from the user information storage unit 141 and the read unique user name is displayed on the display unit 110 as a response destination user name. Here, the display control unit 158 displays the response destination user name at a predetermined position associated with the position where the message included in the message information is displayed on the message screen (step S232). That is, in this case, the display control unit 158 performs processing similar to the processing in step S230 in FIG.

  On the other hand, if it is determined in step S225 that the unique user name is not registered (step S225: NO), the display control unit 158 displays the basic associated with the reply destination user ID included in the message information. The user name is read from the user information storage unit 141, and the read basic user name is displayed on the display unit 110 as a response destination user name. Here, the display control unit 158 displays the response destination user name at a predetermined position associated with the position where the message included in the message information is displayed on the message screen (step S234).

  The subsequent processing in step S240 is the same as the processing in step S240 in FIG. 5, and the received messages are displayed in time series on the display unit 110 based on the transmission date and time information.

  Instead of the received message described above, a message to be transmitted may be used. For example, the display control unit 158 determines whether or not the reply destination user ID is included in the message information of the message to be transmitted, and determines whether or not the unique user name is registered by the registration unit 156. Good. If the unique user name is registered, the display control unit 158 displays the unique user name in association with the message to be transmitted. If the unique user name is not registered, the display control unit 158 displays the basic user in the message to be transmitted. The names may be displayed in association with each other.

As described above, the user terminal 100 according to the present embodiment uses the basic user name (second second user information) as information indicating another user set by each of a plurality of other users (second users). , An acquisition unit 155 that acquires the identification information (user ID) uniquely identifying each other user is provided. Further, the user terminal 100 identifies the unique user name registered by the registration unit 156 (the first second user information) and the basic user name acquired by the acquisition unit 155 to uniquely identify other users ( And a management unit 157 for managing in association with the user ID.
The message received by the message receiving unit 153 is associated with identification information (response destination user ID) that uniquely identifies the response destination user (third user), and the identification information (response destination user) It is assumed that a unique user name corresponding to (ID) is registered by the registration unit 156. At this time, the display control unit 158 uses the unique user name corresponding to the identification information (response destination user ID) among the unique user names registered by the registration unit 156 as information indicating the response destination user in the received message. The information is displayed on the display unit 110 in association with each other.
On the other hand, the identification information (response destination user ID) uniquely identifying the response destination user (third user) is associated with the message received by the message receiving unit 153, and the identification information (response destination user) It is assumed that the unique user name corresponding to (ID) is not registered by the registration unit 156. At this time, the display control unit 158 displays the basic user name corresponding to the identification information (response destination user ID) among the basic user name (second second user information) acquired by the acquisition unit 155 as the response destination user. Information to be displayed is displayed on the display unit 110 in association with the received message.

  That is, the display control unit 158 displays the unique user name when the unique user name is registered as information indicating the reply destination user to be displayed in association with the received message, and the unique user name is registered. If not, display basic user name.

  Thereby, when the unique user name is registered, the user terminal 100 sets the unique user name to the user name as the reply destination of the message (response message) and the user name of the other user (chat partner). And can be displayed on the display unit 110. On the other hand, when the unique user name is not registered, the user terminal 100 uses the basic user name for the user name as the reply destination of the message (response message) and the user name of the other user (chat partner). Can be displayed on the display unit 110. Therefore, the user terminal 100 can match the user name as a reply destination of the message (response message) displayed on the message screen with the user name of another user (chat partner).

In the user terminal 100, identification information (response destination user ID) uniquely identifying the response destination user (third user) selected by the operation reception unit 120 (input unit) in the message transmitted by the message transmission unit 152. Assume that the registration unit 156 registers a unique user name (first second user information) corresponding to the identification information (response destination user ID). At this time, the display control unit 158
Of the unique user names registered by the registration unit 156, the unique user name corresponding to the identification information (response destination user ID) is displayed on the display unit 110 as information indicating the response destination user in association with the message to be transmitted. .
On the other hand, identification information (response destination user ID) that uniquely identifies the response destination user (third user) selected by the operation reception unit 120 (input unit) is associated with the message transmitted by the message transmission unit 152. It is assumed that the unique user name corresponding to the identification information (response destination user ID) is not registered by the registration unit 156. At this time, the display control unit 158 displays the basic user name corresponding to the identification information (response destination user ID) among the basic user name (second second user information) acquired by the acquisition unit 155 as the response destination user. Information to be displayed is displayed on the display unit 110 in association with the message to be transmitted.

  That is, the display control unit 158 displays the unique user name when the unique user name is registered as information indicating the reply destination user to be displayed in association with the message to be transmitted, and the unique user name is registered. If not, display basic user name.

  Thereby, when the unique user name is registered, the user terminal 100 sets the unique user name to the user name as the reply destination of the message (response message) and the user name of the other user (chat partner). And can be displayed on the display unit 110. On the other hand, when the unique user name is not registered, the user terminal 100 uses the basic user name for the user name as the reply destination of the message (response message) and the user name of the other user (chat partner). Can be displayed on the display unit 110. Therefore, the user terminal 100 can match the user name as a reply destination of the message (response message) displayed on the message screen with the user name of another user (chat partner).

  As described above, according to the user terminal 100 of the present embodiment, it is possible to display a message with improved convenience.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. Since the configuration of the chat system 1 of the present embodiment is the same as that of the first embodiment, a characteristic process in the present embodiment will be described. The display control unit 158 according to the present embodiment displays information indicating a reply destination user in a balloon displaying a message. For example, the display control unit 158 adds information (text) indicating the reply destination user to the head of the message and causes the display unit 110 to display the information.

  18 and 19 are diagrams illustrating examples of message screens according to the present embodiment. With reference to FIGS. 18 and 19, an example in which information (text) indicating a reply destination user is added to the head of a message and displayed on the display unit 110 will be described.

  FIG. 18 is a diagram illustrating an example of a message screen displayed on the display unit 110 of the user terminal 100 of the user (user A). The message screen shown in FIG. 18 differs from the message screen shown in FIG. 12 in that information indicating a reply destination user is displayed in a balloon. Here, the user information shown in FIG. 8 is stored in the user terminal 100-1 of the user A. That is, in the user terminal 100-1 of the user A, the unique user name of the user B is registered as “company boss”. In FIG. 18, a message that user A (own user) transmits user B as a reply destination user is displayed in a balloon E9. Further, in the balloon E9, information indicating a reply (here, “>”) and a reply destination user name (here, the unique user name of the user B “company manager”) are included at the head of the message. It is displayed as information indicating the reply destination user.

  On the other hand, FIG. 19 is a diagram illustrating an example of a message screen displayed on the display unit 110 of the user terminal 100 of another user (user C). The message screen shown in FIG. 19 is different from the message screen shown in FIG. 14 in that information indicating a reply destination user is displayed in a balloon. Here, it is assumed that user information shown in FIG. 13 is stored in the user terminal 100-3 of the user C. That is, the unique user name of the user B is registered as “Mr. Yamada” in the user terminal 100-3 of the user C. In FIG. 18, a message that user A (another user) has transmitted user B as a reply destination user is displayed in a balloon E22. Further, in the balloon E22, information indicating a reply (here, “>”) and a reply destination user name (here, user B's unique user name “Mr. Yamada”) are replied to the head of the message. It is displayed as information indicating the previous user.

  As described above, the user terminal 100 according to the present embodiment displays information indicating the response destination user at the head of the message displayed in the balloon based on the response destination user ID associated with the message. Accordingly, the user terminal 100 can display the response destination user name on the display unit 110 as if it was input as a part of the message. Therefore, the user can easily determine to which user in the group the message displayed on the message screen has been replied. That is, according to the user terminal 100 of the present embodiment, it is possible to display a message with improved convenience.

  Note that the information indicating the reply destination user displayed in a part of the message (at the beginning of the message) in the balloon is not limited to the unique user name, as described in the first and second embodiments. , At least one of a basic user name, a user image, a user ID, an e-mail address, and the like.

<Fourth Embodiment>
Next, a fourth embodiment of the present invention will be described. Since the configuration of the chat system 1 of the present embodiment is the same as that of the first embodiment, a characteristic process in the present embodiment will be described. The registration unit 156 according to the present embodiment registers a unique user name (first second user information) based on user information registered in another function.

  Here, the other function is a function different from the chat function by the chat application described above, for example, a telephone function installed in the user terminal 100. For example, the registration unit 156 registers the name included in the user information in the telephone book (address book) as a unique user name based on the user information in the telephone book (address book) registered in the telephone function. .

  Note that the registration unit 156 assigns either one of the user names of the other users uniquely input by the user in the chat function and the user names included in the user information registered in the other functions to the unique user. It is good also as a structure registered as a name, and it is good also as a structure which registers each user name as two types of unique user names. Here, in the case of a configuration in which two types of unique user names are registered, one of the unique user names may be given priority.

  For example, the registration unit 156 registers the user name of the other user uniquely input by the own user in the chat function as the unique user name (here, the unique user name N1). Also, the registration unit 156 registers the name included in the user information in the telephone book (address book) as a unique user name (here, a unique user name N2). Here, the unique user name N2 is registered, for example, by executing a telephone directory (address book) linkage function that the chat function has. Specifically, by executing this interlocking function, information (user ID, e-mail address, etc.) that can identify the user in the telephone book (address book) and the user included in the user information in the chat function are displayed. Matchable information (user ID, e-mail address, etc.) is collated. For the user whose matching result matches, the name included in the user information in the phone book (address book) is registered as the unique user name N2.

  20 and 21 are diagrams illustrating examples of user information stored in the user information storage unit 141 according to the present embodiment. In this figure, the user information stored in the user information storage unit 141 includes two types of unique user names, a unique user name N1 and a unique user name N2.

  FIG. 20 is a diagram illustrating an example of user information after the registration unit 156 executes the process of registering the unique user name N2 in the user terminal 100-1 of the user A. Here, for user B, a unique user name N2 (here “Yamada Senpai”) is registered based on the name included in the user information in the telephone directory (address book). For user C, it is assumed that there is no user information corresponding to user C in the user information in the telephone directory (address book), and the unique user name N2 is not registered.

  For example, when the display control unit 158 refers to the user information stored in the user information storage unit 141 and displays the user name as information indicating the user B, the display control unit 158 includes the unique user name N2 (here) Then “Yamada Senpai”) is displayed. Further, when displaying the user name as information indicating the user C, the display control unit 158 displays a basic user name (here, “Takahashi C child”) corresponding to the user C.

  FIG. 21 is a diagram illustrating an example of user information in which the user A uniquely registers the unique user name after the registration unit 156 executes the process of registering the unique user name N2 in the user terminal 100-1 of the user A. is there. Here, the unique user name N2 is registered for the user B as in FIG. In addition, as the unique user name N1, the unique user name N1 (here, “company boss”) input by the user A for the user B is registered. For user C, a unique user name N1 (here, “company subordinate”) that user A originally entered is registered.

  For example, when the display control unit 158 refers to the user information stored in the user information storage unit 141 and displays the user name as information indicating the user B, the unique control user name N1 (here) Then, “Company boss”) is displayed. Further, when displaying the user name as information indicating the user C, the display control unit 158 displays the unique user name N1 (here, “company subordinate”) corresponding to the user C. That is, the display control unit 158 displays the unique user name with priority over the basic user name, and displays the unique user name N1 with priority over the unique user name N2.

  That is, in any case of the user information shown in FIG. 20 and FIG. 21, the display control unit 158 is the same when the user name and the reply destination user name of the user who sent the message are the same user. Displays the user name of. Further, the display control unit 158 gives priority to the unique user name over the basic user name, and displays the unique user name N1 with priority over the unique user name N2 among the unique user names.

  As described above, in the user terminal 100 according to the present embodiment, the registration unit 156 registers a unique user name (first second user information) based on user information registered in another function.

  Thereby, the user terminal 100 can register a name included in the user information as a unique user name based on user information registered in another function (for example, a telephone function). Therefore, the user terminal 100 registers the name included in the user information registered in the other function as the unique user name even if the own user does not perform an operation of registering the unique user name of the other user in the chat function. Can do.

  The user terminal 100 also includes a unique user name N2 based on a name included in user information registered in another function and a unique user name N1 based on the user name of the other user that the user himself / herself has input in the chat function. Can be registered. Thereby, for example, when the unique user name N1 is not registered, the user terminal 100 displays the unique user name N2, and then when the unique user name N1 is registered, the user terminal 100 uses the unique user name N2. Also, the unique user name N1 can be displayed with priority.

  The priority order of the unique user name N1 and the unique user name N2 described above is an example, and the unique user name N2 may be prioritized over the unique user name N1. The other functions described above are not limited to the telephone function installed in the user terminal 100, but are a mail function, an SNS (Social Networking Service) function, and a mini blog (microblog, tweet blog) function. May be. That is, it may be a function provided by an external service. Specifically, an account name in the SNS function can be exemplified as the unique user name N2.

<Fifth Embodiment>
Next, a fifth embodiment of the present invention will be described. Since the configuration of the chat system 1 of the present embodiment is the same as that of the first embodiment, a characteristic process in the present embodiment will be described. If the reply destination user included in the received message information is not the own user (the user who received the message) (that is, not the message addressed to himself / herself), the display control unit 158 according to the present embodiment receives the received message. Is not displayed on the message screen (not displayed).

  FIG. 22 is a flowchart illustrating an example of a message display process according to the present embodiment. With reference to FIG. 22, the operation of the message display process according to the present embodiment will be described. In FIG. 22, processes corresponding to those in FIG. 15 are denoted by the same reference numerals, and description thereof is omitted as appropriate.

    First, similar to the processing described with reference to FIG. 15, the message receiving unit 153 receives message information transmitted from the user terminal 100 of another user (step S210), and the display control unit 158 receives the received message. It is determined whether or not the response destination user ID is included in the information (step S220).

  When it is determined in step S220 that the reply destination user ID is not included (step S220: NO), the display control unit 158 arranges the display units in time series based on the transmission date and time information included in each message information. 110 is displayed (step S240).

  On the other hand, when it is determined in step S220 that the reply destination user ID is included (step S220: YES), the display control unit 158 indicates that the reply destination user ID is the user of the own user (the user who received the message). It is determined whether or not it matches the ID (step S222).

  When it is determined in step S222 that the reply destination user ID does not match the user ID of the user (step S222: NO), the display control unit 158 displays the message included in the received message information on the display unit 110. Not (not displayed) (step S250).

  On the other hand, if it is determined in step S222 that the response destination user ID matches the user ID of the user (step S222: YES), the display control unit 158 displays the received message information without displaying the response destination user name. Are displayed on the display unit 110 in time series (step S260).

  As described above, in the user terminal 100 according to the present embodiment, the display control unit 158 identifies the identification information (response destination user ID) that uniquely identifies the response destination user (third user) in the message received by the message reception unit 153. ) And the identification information (response user ID) does not match the identification information (user ID) that uniquely identifies the user (first user). The message is not displayed on the display unit 110.

  Accordingly, when the user terminal 100 receives a message in which the response destination user is selected, the user terminal 100 can display only the message of the own user (that is, the message addressed to the user). That is, in the chat system 1, the message for which the reply destination user is selected is displayed on the message screen only on the two user terminals 100, that is, the user who transmitted the message and the reply destination user of the message. It can be prevented from being displayed on the user terminal 100 of other users. That is, in the chat system 1, a secret chat between two parties (a chat in which the content of a message is not displayed by anyone other than the two parties) can be performed.

  In the user terminal 100, the display control unit 158 associates identification information (response destination user ID) uniquely identifying the response destination user (third user) with the message received by the message reception unit 153. If the identification information (response destination user ID) matches the identification information (user ID) that uniquely identifies the user (first user), the information indicating the response destination user is not associated. The received message may be displayed on the display unit 110.

  For example, in the chat system 1, when a secret chat between two parties is performed, the message reply destination user is clear, and thus the user terminal 100 does not display information indicating the reply destination user. Thereby, since the user terminal 100 does not display unnecessary information on the message screen, the information (message or the like) displayed on the message screen can be easily viewed.

  Note that in the case of secret chat, the user terminal 100 sets the display mode (character color, font, balloon shape and color, etc.) of the message or balloon displayed on the message screen to be normal chat other than secret chat. You may make it differ. Thereby, the user terminal 100 can display whether or not the message is a secret chat message so that the user can easily determine the message.

  Note that the user terminal 100 can continue the secret chat by transmitting a message that responds to the message by the secret chat (for example, selecting a message by the secret chat and transmitting the message).

  In the above embodiment, the user terminal 100 receives a response when the response destination user included in the received message information is not the own user (the user who received the message) (that is, the message is not addressed to the user). Explained the process of not displaying the message on the message screen. On the other hand, in the chat system 1, when the server device 200 associates a response destination user ID with a message transmitted from each of the user terminals 100 of each user in the group, the response destination user ID indicates The message may be transmitted only to the user terminal 100 of the user. As a result, since a message indicating that the response destination user is another user is not transmitted from the server device 200, a message indicating that the response destination user is another user is not displayed on each message screen of the user terminal 100 of each user. In other words, the server device 200 transmits the message only to the user terminal 100 of the user indicated by the response destination user ID associated with the message transmitted from each of the user terminals 100 of each user in the group. In the chat system 1, the secret chat between the two parties as described above can be performed.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above-described embodiment, and includes a design and the like within a scope not departing from the gist of the present invention. For example, the functions described in the first to fourth embodiments can be arbitrarily combined.

  In the above-described embodiment, when the date and time information associated with the message included in the message information is a message transmitted from another user, the date and time when the message was transmitted (actually, the message is transmitted to the server device). In this example, when the message is a message transmitted by the user, the server apparatus 200 receives the message as information indicating the date and time when the server apparatus 200 has received the message. However, in the case of a message transmitted from another user, information indicating the date and time when the message was actually transmitted in the user terminal 100 of the other user may be received together with the message and used as the date and time information. The date and time transmitted from the apparatus 200 can be received together with the message and used as date and time information.

  Moreover, although the operation reception part 120 and the display part 110 were comprised integrally and demonstrated the example which applied the touchscreen which receives the operation input from a user in the above-mentioned embodiment, the operation reception part 120 and the display part 110 were demonstrated. Alternatively, a keyboard or a button may be applied as the operation receiving unit 120. Further, the operation receiving unit 120 may be configured as an operation input unit capable of performing an operation input by voice recognition. In the above-described embodiment, the example in which the display unit 110 is integrally configured in the user terminal 100 has been described. However, the configuration is not limited thereto, and the configuration is such that the external display unit (display device) is connected by wire or wirelessly. Also good.

  Moreover, although the example of the control in the chat application has been described in the above-described embodiment, as described above, an e-mail, an electronic bulletin board, a timeline, a miniblog ( The above-described embodiment can be applied to control in a micro blog, a tweet blog, or the like. Here, the e-mail may be an e-mail transmitted and received by a short message service using a mobile phone or the like. That is, instead of the chat system 1 shown in the above-described embodiment, the above-described embodiment can be applied to a mail transmission / reception system other than the above-described chat. Note that the control in the chat application is more suitable from the viewpoint of immediacy of the display of messages transmitted and received between users.

Further, the embodiment of the present invention is not limited to the above-described example, and can take various forms within the scope of the present invention. For example, the components included in the chat system 1 described above can be distributed or aggregated and arranged in any computer device. For example, the server device 200 is distributed or aggregated to any computer device according to the cloud environment, the network environment, the size of the number of users, the number of hardware prepared to configure the chat system 1, specifications, and the like. Can be arranged.
Further, for example, the server device 200 stores all messages transmitted and received between the plurality of user terminals 100, transmits the message in response to an arbitrary request from the user terminal 100, and causes the user terminal 100 to display the message. It may be.
In the above-described embodiment, an example in which a plurality of user terminals 100 transmit and receive messages via the server device 200 has been described. However, a plurality of user terminals 100 directly transmit and receive messages without using the server device 200. May be.

  The program for realizing the functions of the control unit 150 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by the computer system and executed, thereby executing the control unit. 150 processes may be performed.
