As shown in this figure, the user table TBL11 includes user identification information UIDa for uniquely identifying a user, an image identifier GaID indicating the user's avatar image (user image) data Ga, and a password PSW. The mail address Mailadd and the friend's user identification information UIDa are stored in association with each other. In order to receive the service provided by the message display system 100, it is necessary to perform user registration. When the user registration is performed, the CPU 30 writes various information in the user table TBL11. The avatar image is set by the user at the time of user registration.

  FIG. 4 shows the data structure of the external account table TBL12. As shown in this figure, in the external account table TBL12, user identification information UIDa and external account information are stored in association with each other. When the external account information is accessed to the external server devices 3B, 3C, 3D,..., The server device 3A is required to obtain authentication from the external server devices 3B, 3C, 3D,. It consists of a set of information and user identification information in the external server device. As will be described later, external account authentication is performed to allow the message display system 100 to permit on behalf of the user in order to acquire message information of the external server device. The external server device confirms the user identification information and password input by the user, issues an access token, and notifies the server device 3A of the access token. User identification information UIDb to UIDd correspond to external server devices 3B to 3D, respectively. In the present embodiment, the server apparatus 3A performs external account authentication in order to obtain authentication from the external server apparatuses 3B, 3C, 3D... On behalf of the user, but the server apparatus 3A performs external authentication on behalf of the user. Other methods that can obtain authentication from the server devices 3B, 3C, 3D,...

CPU20 functions as a display control part, and displays a user's avatar, when displaying a message (contents of a message) on the display 25. FIG. At this time, with reference to the avatar table TBL21, it is determined whether or not the avatar image data Ga having the image identifier GaID corresponding to the user identification information UIDa is stored. Avatar image data Ga is acquired by transmitting to 3A and stored in the avatar table TBL21. Thereby, the avatar image data Ga required in the terminal device 2 is stored in the avatar table TBL21.

<1-2: Operation of the message display system>
Next, the operation of the message display system 100 will be described. FIG. 8 shows an operation sequence related to external service registration. In this example, it is assumed that the service b provided by the user of the terminal device 2 with the external server device 3B is registered in the message display system 100.

  When a user of the terminal device 2 starts an application such as a web browser and accesses a login page provided by the server device 3A, a login screen is displayed on the display 25 of the terminal device 2. On this login screen, an input box for inputting the user identification information UIDa and the password PSW is displayed. When the user inputs in the input box and presses the send button, the terminal device 2 transmits a login request including the input user identification information UIDa and the password PSW to the server device 3A.

  When the server apparatus 3A receives the login request, the server apparatus 3A executes an authentication process (S1). Specifically, the CPU 30 refers to the user table TBL11 to determine whether or not a set of the user identification information UIDA and the password PSW input by the user is stored, and satisfies the determination condition Login is permitted, and if the determination condition is not satisfied, the login is rejected. Then, the CPU 30 causes the terminal device 2 to transmit a login response indicating the determination result. In the example shown in FIG. 8, it is assumed that login is permitted.

  Thereafter, it is assumed that the user selects a menu and selects an external service registration screen. FIG. 9 shows an example of a registration screen. As shown in this figure, buttons 210 to 212 are displayed on the registration screen to prompt the user to select which external service to select. Here, it is assumed that the user clicks the button 210 and selects the external service b (S2). Then, the CPU 20 transmits an external service registration request indicating registration for the external service b to the server device 3A.

  The server apparatus 3A that has received the registration request transmits to the external server apparatus 3B an authentication request for the server apparatus 3A to access the external service on behalf of the user, and the external server apparatus 3B that has received the authentication request receives the request token Is issued (S3). Then, the server device 3A executes (redirect) transfer processing (S4) for causing the terminal device to access the URL of the authentication screen of the external server device 3B in which the request token is added to the parameter. FIG. 10 shows an example of the authentication screen.

  As shown in this figure, an input box 220 for inputting user identification information, an input box 221 for inputting a password, a login button 222, and a cancel button 223 are displayed on the authentication screen. When the user inputs the user identification information UIDb corresponding to the external service b in the input box 220 and also inputs the password in the input box 221 (S5) and presses the login button 222, the terminal device 2 sends an authentication request to the outside. It transmits to the server apparatus 3B.

When the external server device 3B receives the authentication request, it is determined whether or not the external server device 3B is a valid user based on the combination of the user identification information UIDb and the password PSW included in the authentication request (S6). ). In this example, a valid user is assumed. In this case, the external server device 3B authorizes the request token, and causes the terminal device to access the URL of the registration screen of the server device 3A in which the authorized request token is added to the parameter (redirect).
The server device 3A transmits an access token request having an access right to the external server device 3B. The external server device 3B that has received the access token request issues an access token based on the authentication information such as the user identification information UIDb and the authorized request token (S7), and transmits the issued access token to the server device 3A. To do.

  When the server device 3A receives the access token, the server device 3A acquires the user identification information UIDb in the external server device 3B from the external server device 3B, and sets the combination of the user identification information UIDb and the access token to the user identification of the server device 3A. It is stored in the external account table TBL12 in association with the information UIDa (S8).

Next, FIG. 11 shows an operation sequence for displaying a message. Since the process from login request → authentication process (S1) → login response is similar to the registration of the external service described with reference to FIG. 8, the description thereof is omitted here.
When the user of the terminal device 2 (hereinafter sometimes referred to as “user A” for convenience of explanation) selects a message type such as an article posted on a bulletin board, mail, or chat on the menu screen, the terminal device 2 For the selected type of message, an instruction regarding the display of the thread is received from the user A (S21). Next, the terminal device 2 transmits a browsing request to the server device 3A. When the server device 3A receives the browsing request, the CPU 30 determines whether or not there is an external account registration corresponding to the user identification information UIDa of the user A by searching the external account table TBL12 (S22).

  If the determination result is negative, the CPU 30 executes a service providing process (S26) described later. On the other hand, when the determination result is positive, the CPU 30 acquires external account information of the external service corresponding to the user identification information UIDa in the server device 3A from the external account table TBL12 (S23). This external account information consists of a set of an access token and user A's user identification information UIDb. When a plurality of external account information is registered, all registered account information is acquired. In this example, it is assumed that the external account information of the external server device 3B has been acquired.

  Thereafter, the server device 3A transmits a browsing request including the user identification information UIDb and the access token to the external server device 3B. When the external server device 3B receives the browsing request, the external server device 3B executes an authentication process using the access token. If the user is a valid user, the external server device 3B executes an extraction process (S24).

Specifically, message information related to user identification information UIDb of user A is extracted. Specifically, message information regarding messages included in all threads related to user A is extracted.
The external server device 3B transmits a browsing response including the set of the message information extracted by the extraction process and the user identification information UIDb to the server device 3A.

  Thereafter, the server device 3A executes a UID conversion process (S25). The browsing response includes user identification information UIDb used in the external server device 3B. For users who are users of the message display system 100 and registered in the external service b, user identification information UIDa and user identification information UIDb are stored in the external account table TBL12 in association with each other. . In the UID conversion process, the CPU 30 refers to the external account table TBL12, converts the user identification information UIDb acquired from the external server device 3B into user identification information UIDa used in the server device 3A, and outputs the user identification information UIDa. However, the user identification information UIDb that does not have the corresponding user identification information UIDa is converted into non-existence identification information NID indicating that fact. Thereby, user identification information UIDb is converted into user identification information UIDa or non-existence identification information NID among the set of message information and user identification information UIDb acquired from external server device 3B.

  Next, the server device 3A executes a service providing process (S26). Specifically, the CPU 30 refers to the message database DB and reads the message information stored in association with the user identification information UIDA of the user A of the terminal device 2. Further, the CPU 30 refers to the user table TBL11 and reads out the friend user identification information UIDa stored in association with the user identification information UIDa of the user A of the terminal device 2. Next, the CPU 30 refers to the message database DB and acquires message information stored in association with the user identification information UIDa of the friend. Further, the image identifier GaID associated with the user identification information UIDa is acquired with reference to the user table TBL11. Thus, CPU30 acquires the message information read from message database DB, the message information acquired from the external server apparatus 3B, and the information regarding an avatar image, and transmits the browsing response containing these to the terminal device 2. FIG. Each message information is associated with corresponding user identification information UIDa or non-existence identification information NID, and this identification information is also included in the browsing response.

  When the terminal device 2 receives the browsing response, the CPU 20 determines whether or not the avatar image data Ga of the image identifier GaID associated with the user identification information UIDa corresponding to the message information is stored in the avatar table TBL21. If it is stored, the avatar image data Ga is acquired (S27). When there is an image identifier GaID that is not stored in the avatar table TBL21, the terminal device 2 includes the image identifier GaID that is not stored in the avatar image request and transmits it to the server device 3A.

When server device 3A receives the avatar image request, CPU 30 executes an avatar image extraction process (S28). In this case, the CPU 30 reads the avatar image data corresponding to the image identifier GaID with reference to the avatar table TBL13. Then, the CPU 30 returns an avatar image response including a set of the read avatar image data and the image identifier GaID to the terminal device 2.
When the terminal device 2 receives the avatar image response, the CPU 20 stores the set of the avatar image data and the image identifier GaID included in the avatar image response in the avatar table TBL21.

Thereafter, the CPU 20 of the terminal device 2 executes display processing (S29). FIG. 12 shows an example of a screen displayed on the display 25 of the terminal device 2 by display processing. As shown in this figure, a circle C is displayed for each thread on the screen, and avatars of persons who participate in the thread are displayed in the circle C. Each circle C is provided to display an avatar image (user image) belonging to a thread, and corresponds to a thread display area provided separately for each thread. That is, the CPU 20 performs control so that a user image indicating a sender of each message included in a thread to be displayed (a plurality of threads in this example) is displayed in a thread display area provided separately for each thread. Functions as a display control unit.
In addition, the size of each circle C changes according to the number of message information included in the thread (that is, the number of messages). The display order of the plurality of threads is arranged from the top of the screen in the order of latest transmission time of the latest message information in each thread. Also, if the user slides the screen, the screen scrolls so that the status of other threads can be grasped.

FIG. 13 shows the processing contents of the display processing. First, the CPU 20 of the terminal device 2 identifies the newest time information of message information included in each thread, compares the identified time information, and the thread corresponding to the latest time information is positioned at the top. Then, the display order of the threads is determined so as to be arranged in time order (S31).
Next, the CPU 20 counts the number of message information included in each thread (S32), and determines the size of the circle according to the counted value (S33). Note that the CPU 20 may change the area of the circle C according to the number of avatars displayed on the circle C. That is, when the number of message information and avatars increases, the area of the circle C is increased.

  Further, the CPU 20 specifies an avatar image corresponding to the user identification information UIDa (S34). Specifically, the CPU 20 reads the avatar image data Ga of the image identifier GaID corresponding to the user identification information UIDa corresponding to the message information from the avatar table TBL21. In addition, when the absence identification information NID is associated with the message information, avatar image data indicating a predetermined avatar image is read. For example, an avatar Ax indicated by a shadow in FIG. 12 corresponds to a predetermined avatar image.

As described above, in this example, the message information includes information acquired from an external server device. That is, the message information may be managed by the external server devices 3B, 3C, 3D... That are external services outside the message display system 100. In such a case, a message transmitted by a person who is not a user of the message display system 100 may be included in the thread. The user identification information UIDa corresponding to this message includes the corresponding user identification information UIDa. not exist. For this reason, in the above-described UID conversion process, the user identification information UIDb is previously converted into the absence identification information NID by the CPU 30 of the server device 3A.
Therefore, in this embodiment, when the message information is associated with the non-existence identification information NID, that is, when the sender of the message is a non-user of the message display system 100, a predetermined user is used. I try to get an image. That is, when the message information is managed by an external service outside the message display system, the CPU 20 and the CPU 30 display the user image corresponding to the identification information of the sender of the message included in the thread to be displayed. When it cannot be acquired from the storage unit, it functions as a display control unit that controls to display a predetermined user image when a user image corresponding to the identification information of the sender of the message cannot be acquired.

  Next, based on the time information, the CPU 20 arranges the avatar so that the distance from the person who first transmitted the message (if a post is a contributor) is closer to the latest message response. (S35). Here, only the avatar of the person who sent the message first (poster) faces away from the screen, and the other avatars face the direction of the person who sent the message first. It is preferable to display the avatar of the person who sent it so that it can be easily identified. Further, the CPU 20 adds a mark S to the person who first transmitted the message (S36). This makes it possible to distinguish the sender who first sent the message from other people and display it, and if the message type is a posted article on a bulletin board or the like, the poster can be found at a glance.

  In addition, a number of avatars (user images) corresponding to the number of users who transmitted message information are displayed in a circle C (thread display area) provided separately for each thread. For this reason, a thread in which a large number of users send messages is crowded because a large number of user images are displayed, and a thread with few messages has a small number of user images and is quiet. That is, it is possible to visually display how many users have transmitted messages, and the user can easily grasp the spread of communication visually. Circle C displays how many users have sent messages using different user images for each user. For this reason, compared with the case where a single user image is used, the spread of communication can be grasped visually more easily. In the present embodiment, even a non-user of the message display system 100 acquires and displays a predetermined user image, so that the spread of communication including the non-user can be easily understood visually. It becomes possible. At a glance, the user can know how much a non-user is sending a message.

  Furthermore, the area of the circle C changes according to the number of users who transmitted the message. For this reason, the circle C (thread display area) is expanded in threads where communication is active, so that the spread of communication can be easily understood visually.

Next, a case where the message type is a posted article on a bulletin board or the like will be described. On the screen shown in FIG. 12, when the circle C of “service a bulletin board” is tapped, the bulletin board screen shown in FIG. 14 is displayed. The bulletin board screen is provided with a message display area B at the upper part of the circle C (thread display area), where posts and responses to the bulletin board are displayed. That is, it is convenient because the user image and the message are displayed on the same screen in units of threads.
In this example, a message M6, a message M5, and a message M4 are displayed. The avatars corresponding to each of the messages M6 to M4 are A6 to A4. The avatars A6, A5, and A4 are arranged in the order of the avatars A0 of the poster to which the mark S is added. The messages M6 and M5 , M4 in order of new responses. Thereby, since a message and an avatar (user image) can be linked | related, the convenience improves. The arrangement of the avatars A0 to A6 in the circle C is the same as the method described with reference to FIG.

  Also, as shown in FIG. 20, an image may be displayed in the image display area X based on image data attached to the message by the poster (image data attached to the message). When image data is attached to the response to the posting, the image attached to the image data may be displayed. In this case, the image attached by the responder may be displayed around the circle C (thread display area) or may be displayed beside the messages M6, M5, and M4 displayed in time series.

  Next, when the user touches the message display area B and moves his / her finger up and down, the messages displayed in the message display area B scroll in time series. In this case, when the message displayed in the message display area B is changed, the CPU 20 includes message information included in the thread at the time when the message displayed in the lowermost stage (predetermined position) of the message display area B is transmitted. Depending on, the avatar is displayed. As described above, since the message is displayed so as to be changeable in time series, it is not necessary to expand the message display area B even when there are many messages. Therefore, a sufficient area of the circle C (thread display region) can be secured.

Further, the area of the circle C (thread display area) is changed according to the number of messages at that time. That is, when the number of messages is large, the area of the circle C is enlarged, and conversely, when the number of messages is small, the area of the circle C is reduced. The area of the circle C (thread display area) may be changed according to the number of one-click responses included in the thread. That is, when the number of one-click responses is large, the area of the circle C is expanded. As a result, the area of the thread display area is determined according to the number of communications that do not rely on character input (for example, “Like!”), So the spread of communication that incorporates simple communications that do not rely on character input can be visualized. Can be easily understood. Also in this case, since the area of the thread display area is changed along the time series, it is possible to know the spread of thread communication in association with the passage of time.
Further, an image attached to a message displayed in the message display area B may be displayed in the image display area.

  For example, as shown in FIG. 15, if the user changes the message displayed in the message display area B until the latest message becomes the message M1, the area of the circle C is the thread at the time when the message M1 is transmitted. This corresponds to the number of messages included in “2”. By changing the area of the circle C according to the change of the message displayed in this way, it is possible to visually grasp the change in the degree of communication in the thread with the passage of time. That is, thread communication can be known in association with the passage of time.

  14 and 15, when a user writes text in the input box 310 and presses the send button 314, a message is transmitted from the terminal device 2 to the external server device 3B.

  Further, the buttons 311 to 312 are buttons (icons) for communication that does not depend on character input. When the button 311 is pressed, information indicating that the “like!” Button has been pressed is transmitted. When the button 312 is pressed, information indicating that the “Why?” Button has been pressed is transmitted. When the button 312 is pressed, information indicating that the “Bad” button has been pressed is transmitted. That is, a message (third message) that does not depend on character input is transmitted according to the icon selected by the user. The communication message that does not depend on the character input transmitted in this way may be counted in the same manner as a normal message to vary the area of the circle C.

  Since such a fixed message is displayed with a button, the user can easily participate in communication by simply pressing this button without the need for character input (text input). In addition, without participating as a party in the bulletin board conversation, it is possible to participate from the standpoint of a third party, such as simply showing approval or disapproval of the message, evaluation of good or bad. It can be said that the larger the number of messages (third messages) that do not depend on the character input, the more the attention is received from other than the participants of the bulletin board, and the bulletin board is active as a whole. Therefore, according to this aspect, since the area of the thread display area is determined including the number of times of communication not depending on character input, it is easy to visually understand the spread of communication incorporating simple communication that does not depend on character input. It becomes possible to know.

  14 and 15 show examples of fixed message such as “Like!”, “Why?”, And “Bad”. However, the message is not limited to the fixed message, and may be a message expressed by a pictograph or a symbol. There may be. For example, a picture of applause may be used instead of “Like!”, A “?” Mark instead of “Why?”, And a hand picture with a thumb pointing down instead of “Bad”. Note that a message in which a fixed phrase is displayed as a button and a message represented by a pictograph or a symbol are both included in a message (third message) that does not depend on character input.

  When the user clicks the button 330 shown in FIG. 14, the CPU 20 detects this and displays the operation selection screen shown in FIG. 16 on the display 25, for example. The action selection screen is a screen for selecting an action to be given to the avatar. The annular dial section 400 is divided into a plurality of areas, and operation information to be given to the avatar is assigned to each area. The annular dial portion 400 is rotated by touching with a finger and sliding. In the center area 410, an avatar action based on the action information assigned to the area indicated by the instruction unit 420 is displayed. That is, an operation assigned to the area indicated by the instruction unit 420 is selected.

Operation information is assigned to each operation to be selected. When the operation is selected, the CPU 20 transmits the posting or response message information including the operation information. The server device 3A that has received the message stores the message information in association with the user identification information UIDa.
Moreover, when the terminal device 2 receives the browsing response including the operation information as the browsing response, the CPU 20 controls the avatar to operate based on the operation information included in each message information.
Thereby, in the bulletin board screen shown in FIG. 14, it is possible to give actions to each of the avatars A0 to A6 displayed in the circle C, and participants to the thread can look at the thread display without reading the message. You can see at a glance what emotions each person has.

  The movements are not limited to those related to emotions.For example, the movement of the rhythm by shaking the body, the action of bending the knees of bending and stretching movements, the action of looking over Kyokoro to look for something, etc. May be executed. Responses to posts may be made multiple times by the same user. Therefore, when the same user specifies “anger” in the operation information added to certain message information and specifies “joy” in the operation information added to other message information, the CPU 20 determines the latest message. Information may be specified, and the avatar may be operated based on the operation information added to the specified message information. Or CPU20 may acquire the ratio of the operation | movement designated with the operation information of the same user based on the operation information added to each message information, and you may make it switch the operation | movement of an avatar according to the acquired ratio. For example, if the ratio of “anger” and “joy” is 1: 3, the avatar may perform “anger” once, and “joy” three times. The operation process of the avatar is the same in chat and e-mail described later.

  Next, a case where the message type is chat will be described. When a circle C of “external service b chat” is tapped on the screen shown in FIG. 12, a chat screen shown in FIG. 17 is displayed. The chat screen is provided with a message display area B at the top thereof, and the contents of the chat are displayed in chronological order there. In this example, a message M0, a message M1, and a message M3 are displayed. Further, the avatars corresponding to the messages M0 and M1 are A0 and A1, respectively, and the avatar A0 to which the mark S is added is the contributor who first transmitted (posted) the message. The arrangement of the avatars A0, A1, and Ax in the circle C is the same as the method described with reference to FIG.

  Similarly to the bulletin board screen described above, when the user touches the message display area B and moves his / her finger up and down, the message displayed in the message display area B scrolls in time series. Yes. In this case, when the message displayed in the message display area B is changed, the CPU 20 changes the message included in the thread at the time when the message displayed in the lowermost stage (predetermined position) of the message display area B is transmitted. In response, an avatar is displayed. In addition, the area of the circle C (thread display area) is changed according to the number of message information (that is, the number of messages) at that time. Note that the area of the circle C may be changed according to the number of avatars displayed on the circle C at the time. That is, when the number of messages and avatars increases, the area of the circle C is increased. Conversely, when the number of messages and the number of avatars decrease, the area of the circle C is reduced.

  Next, a case where the message type is mail will be described. When the circle “Service a mail” is tapped on the screen shown in FIG. 12, the mail screen shown in FIG. 18 is displayed. The mail screen is provided with a message display area B at the top thereof, where the contents of the mail are displayed in chronological order. In this example, a message M0, a message M1, and a message M2 are displayed. The avatar corresponding to the messages M0 and M2 is A0, and the mark S is the avatar A0 of the person who first transmitted the mail. Regarding the mail display, the area of the circle C may be variable according to the number of message information (number of messages) belonging to the thread.

<2. Modification>
The present invention is not limited to the above-described embodiments, and the following modifications are possible. Moreover, each modification can be combined suitably.
(1) In the above-described embodiment, an avatar is used as an example of an image associated with a user. However, the present invention is not limited to this, and corresponds to a user image serving as a clue to distinguish users. As long as it is attached, it may be anything. For example, other methods that can visually represent a poster or responder, such as “picture” or “graphic”, may be used.

(2) In the above-described embodiment, when someone responds to a message (such as writing a comment), the responder's avatar is displayed around the avatar of the person who first sent the message (for example, the poster). The responder's avatar is arranged in order from the position close to the person who first sent the message, but the present invention is not limited to this, for example, the responder's avatar that responds more frequently You may arrange | position an avatar in arbitrary positions, such as arrange | positioning near a person's avatar.

(3) Alternatively, the avatar may be expressed by a combination of a mascot Ob1 and an identification mark Ob2, as shown in FIG. The mascot Ob1 is a three-dimensional display object (object) simulating a human outline, and the identification mark Ob2 corresponds to an identification image GA for identifying a user (corresponding to the sender of the first message or the second message). The image is a planar display object surrounded by a substantially rectangular frame GB. The identification mark Ob2 is arranged near (above) the mascot Ob1. Here, as the identification image GA, for example, a profile image (such as a portrait or a photograph) registered for the user to display himself / herself on the SNS may be used. In this case, the mascot Ob1 is an image that adopts a general-purpose shape (general-purpose body shape image). Therefore, when adding an operation, operation data for each operation pattern such as “anger” and “joy” can be unified, and the processing load on the terminal device 2 can be reduced. Moreover, since the mascot Ob1 is expressed in three dimensions, there is an advantage that a complicated motion can be added. Further, the user is identified by the profile image, and the body of the avatar is shared by a plurality of users by using a general-purpose image. For this reason, compared with the case where a different avatar image is used for every user, the data amount can be compressed as a whole.

(4) In the above-described embodiment, the avatar is operated to express the emotion. However, the present invention is not limited to this, and the screen for displaying the avatar is changed according to the emotion to be expressed. Anything can be used. For example, a balloon shape may be given to an avatar, and the color or shape may be changed based on emotion. Moreover, you may change the color of avatar itself based on an emotion. For example, if you display a user image in red when you have an angry emotion, and if you display a user image in blue when you have a calm emotion, you don't have to read each message about the topic in the thread. , You can grasp the overall trend instantly. Furthermore, emotions may be expressed by displaying a heart on a signboard. Here, the emotion may be specified on the operation selection screen shown in FIG. 16, and the above-described operation information may be handled as information specifying the emotion.

(5) In the above-described embodiment, the area of the circle C is changed according to the number of messages included in the thread and the number of one-click responses. However, the present invention is not limited to this, and may be blue to red. It may be expressed by a change in color, a change in shading, a change in shape, or the like.
(6) In the above-described embodiment, the mark S is given to the person who first transmitted the message included in the thread. However, the present invention is not limited to this, and the mark S may not be added. Alternatively, a profile image may be used instead of the mark.

(7) In the above-described embodiment, postings and responses are displayed in time series in the message display area B, but the position of the image displayed in the message display area B is, for example, right for the contributor and left for the responder. It may be changed as follows. In this case, it is possible to visually distinguish the poster and the responder.
(8) In the embodiment described above, a mark such as an arrow may be attached to the avatar corresponding to the message displayed in the message display area B. In this case, the contents of the message and the avatar can be grasped in association with each other.

(9) In the above-described embodiment, the server device 3A includes the message database DB and provides a message exchange service between users of the message display system 100. However, the present invention is not limited to this. The message display system 100 may not transmit / receive a message by itself. In this case, the message display system 100 functions as a portal site that integrates and provides services provided by the external server devices 3B, 3C, 3D.

(10) In the above-described embodiment, the motion is expressed on the avatar by selecting the motion on the motion selection screen. However, the present invention is not limited to this, and based on the content of the message. Alternatively, an action for expressing an emotion may be given. In this case, the CPU 20 of the terminal device 2 may analyze the content of the message and determine an operation to be given to the avatar according to the analysis result. More specifically, a table in which keywords are classified for each emotion such as anger and joy is stored in the storage device 23, the emotion estimated from the content of the message is identified with reference to this table, and the identified emotion You may give the operation | movement according to to an avatar. Thereby, even if the user does not select an operation, the user image is automatically operated, so that the burden on the user can be reduced.
Also, when sending a message, various send buttons corresponding to emotions such as joy and anger may be prepared, emotions may be specified according to which transmission button is sent, and an action corresponding to the specified emotions may be given to the avatar. . As a result, when the message is transmitted, the user himself / herself selects the operation, so that the intention of the user is faithfully reflected in the operation of the user image.

(11) In the embodiment described above, the screen to be displayed on the terminal device 2 is generated by the CPU 20 based on the message information. However, the present invention is not limited to this, and the display screen is generated in the server device 3A. Then, this may be transmitted to the terminal device 2.
In the above-described embodiment, the avatar image data Ga is stored in the avatar table TBL21 of the terminal device 2 and the avatar image corresponding to the user is extracted based on the image identifier GaID. However, the present invention is not limited. For example, the server apparatus 3A may transmit the avatar image data Ga to the terminal apparatus 2 in response to a request from the terminal apparatus 2, and the avatar image data Ga is transmitted from the server apparatus 3A to the terminal accompanying the message information. You may transmit to the apparatus 2.

(12) In the embodiment described above, in the avatar tables TBL13 and TBL21, the image identifier GaID and the avatar image (user image) data Ga are stored in association with each other, but the present invention is not limited to this. The user identification information UIDa may be stored instead of the image identifier GaID. In short, identification information for identifying a user and avatar image (user image) data Ga may be stored in association with each other.

(13) In the embodiment described above, in response to the user's browsing request, the message database DB of the server device 3A is referred to read out the message information stored in association with the user and the friend, and the read message A browsing response including information is transmitted to the terminal device 2. The present invention is not limited to this, and the terminal device 2 is provided with a message database DB synchronized with the message database DB of the server device 3A, and the terminal device 2 has a message display instruction in accordance with a thread display instruction from the user. You may make it refer to message database DB. In this case, the message database DB of the terminal device 2 is stored in association with the user identification information UIDa of the user and the user identification information UIDa of the friend with reference to the message database DB of the server device 3A. Of the message information, new message information that is not stored on the terminal device 2 side is acquired at a predetermined timing and synchronized.
If the message information transmitted from the user terminal device 2 is stored in the message database DB of the terminal device 2 as it is, only the message information associated with the friend user identification information UIDa is synchronized. You may make it take.
In such a message display system, the user image indicating the sender of each message information can be divided for each thread based on the message information stored in the message database DB of the terminal device 2 without being connected to the server device 3A. Can be displayed in the thread display area. Further, the message information acquired from the external server devices 3B, 3C, 3D... May be stored in the message database DB of the terminal device 2.
