[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The embodiments described below are merely examples of embodiments of the present disclosure, and the embodiments of the present disclosure are not limited to the exemplary embodiments described below. Therefore, the technical scope of the present disclosure is not limited to the scope described in the embodiments described below. For example, various modifications or improvements to the contents described in the embodiments are also included in the technical scope of the present disclosure. Note that the various functional units described below are realized through the execution of programs by processors such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), or other processors.

[0010] <Terminology> First, the terminology used in the embodiments will be explained. "Program" is used as a general term for the OS (= Operating System) and application programs. "Message" refers to a character string (text) or image sent and received between users. Images include, for example, still images (so-called photographs) and moving images. Pre-prepared standard messages are called stickers or stamps. Messages are also called "comments" or "chat." "Post" refers to a message to be sent, in addition to a user operating the send button.

[0011] A "messaging app" is an application program specialized for sending and viewing messages. A messaging app runs on a device operated by a user. Messages are displayed on the messaging app screen in the order they are posted. A messaging app has a function that displays messages from the user and others in different positions. For example, messages posted by the user operating the device running the messaging app are displayed on the right side of the screen, and messages posted by the other party are displayed on the left side of the screen.

[0012] "User" refers to a natural person who operates a terminal connected to a network. "Terminal" includes not only the terminal operated by the user, but also servers located on the Internet or other networks. Messages posted from a user terminal are delivered to the destination user terminal via a server. A server that relays messages is also called a "relay server." Messages may be enhanced. This enhancement may be implemented as a function of the messaging app or as a function of the relay server.

[0013] <First Embodiment> <System Configuration> Fig. 1 is a diagram showing an example of the configuration of an information processing system 1 assumed in the first embodiment. The information processing system 1 shown in the first embodiment is composed of a server 10 that relays messages, user terminals 20 (20A, 20B) operated by users, and a network N that connects these so that they can communicate with each other. The user terminals 20 send and receive messages via the server 10 on the network.

[0014] The server 10 is one or more computers. When the server 10 is operated by multiple computers, the multiple computers cooperate with each other via a network N. In reality, message relay involves a server operated by a business that provides a message application and one or more servers operated by a business that developed the user terminal 20. The server 10 in FIG. 1 is assumed to be a server operated by a business that provides a message application. The server 10 in this embodiment is an example of an information processing device.

[0015] The user terminal 20 may be, for example, a smartphone, a tablet computer, a notebook or desktop computer, a wearable device, or smart glasses. Smart glasses are eyeglass-type devices equipped with a small display and a light-guiding component that focuses an image displayed on the display on the retina. In the example shown in FIG. 1, there are two user terminals 20, 20A and 20B, but there may be three or more.

[0016] One user is associated with one user terminal 20. In other words, one user account is associated with one user terminal 20. Therefore, in FIG. 1 , user A is associated with user terminal 20A, and user B is associated with user terminal 20B. The network N is assumed to be, for example, the Internet, a LAN (Local Area Network), or a mobile communication system such as 4G or 5G. The network N may be a wired network or a wireless network, or may be a combination of a wired network and a wireless network. For example, the network N may be 5G or another mobile communication system.

[0017] <Server Hardware Configuration> The server 10 is composed of a processor 11 that controls the overall operation of the terminal, a memory 12, an auxiliary storage device 13, and a communication interface 14. The processor 11 is, for example, a CPU. The memory 12 is composed of a ROM (Read Only Memory) that stores a BIOS (Basic Input Output System) and the like, and a RAM (Random Access Memory) that is used as a work area for the processor 11. The auxiliary storage device 13 is, for example, a hard disk drive or semiconductor storage. A program for exchanging messages is installed in the auxiliary storage device 13. The communication interface 14 is a device that enables communication with external terminals such as the user terminal 20. The communication interface 14 is required to have communication functions that are compatible with the network N used for communication.

[0018] <Hardware Configuration of User Terminal> The user terminal 20 is composed of a processor 21 that controls the overall operation of the terminal, a memory 22, an auxiliary storage device 23, a display 24, and a communication interface 25. The processor 21 is, for example, a CPU. The memory 22 is composed of a ROM that stores the BIOS and the like, and a RAM that is used as a work area for the processor 21.

[0019] The auxiliary storage device 23 is, for example, a hard disk drive or semiconductor storage. The auxiliary storage device 23 stores, for example, a message app and messages sent and received through the message app. The display 24 is, for example, a liquid crystal display or an organic EL (Electro Luminescence) display. The communication interface 25 is a device that enables communication with an external terminal such as the server 10. The communication interface 25 is required to have a communication function compatible with the network N used for communication.

[0020] <Functional Configuration of Server> Fig. 2 is a diagram illustrating an example of the functional configuration of the server 10 in the first embodiment. The functional configuration shown in Fig. 2 is an example of a functional unit realized through the execution of a program. The server 10 has an input accepting unit 101 that accepts input of a character string as a message, a display control unit 102 that controls the display mode of the character string, and a storage unit 110. Note that a message in this embodiment is an example of posted information. The storage unit 110 is realized by the memory 12 (see Fig. 1) and the auxiliary storage device 13 (see Fig. 1).

[0021] <Information Stored in Storage Unit> First, an example of information stored in the storage unit 110 will be described. The storage unit 110 shown in Fig. 2 stores a posted message 111 and a performance effect table 112. Note that the storage unit 110 also stores information not shown.

[0022] <Posted Message 111> The posted message 111 is a message exchanged via a messaging app. Fig. 3 is a diagram illustrating an example of the data structure of the posted message 111. The posted message 111 shown in Fig. 3 includes a sending account 111A, a receiving account 111B, a message body 111C, a posting time 111D, and read status information 111E.

[0023] The sending account 111A is information that identifies the user who sent the message. In other words, the sending account 111A is information that identifies the user who posted the message. The sending account 111A uses information that the server 10 uses to authenticate the user (hereinafter referred to as "authentication information"). The authentication information may include, for example, a user name, address, telephone number, email address, and other registered information. The authentication information is managed using an ID (=identifier) ​​and a password. In Figure 3, the notations "User A" and "User B" are used to make it easier to distinguish between the sender and receiver of a message.

[0024] The receiving account 111B is information that identifies the user who received the message. In other words, the receiving account 111B is information that identifies the user to whom the message is addressed. The user's authentication information is also used for the receiving account 111B. The message body 111C is a string or image that provides the body of the message. The string may be a single character, a word, or a sentence. While FIG. 3 shows the case where the message body is a string, the message body may also be an image file. Needless to say, the words or sentences shown in the message body 111C are merely examples. The posting time 111D is the time when the server 10 (see FIG. 1) accepted the posting of the message. The read information 111E is information regarding whether the message has been received by the receiving account 111B. "Read" indicates that the message has been received by the recipient's user terminal 20 (see FIG. 1), and "Not yet" indicates that the message has not been received by the recipient's user terminal 20.

[0025] <Visual Effect Table 112> The visual effect table 112 (see FIG. 2) is a table that stores the relationship between codes that change the display mode of a posted character string message on the user terminal 20 and the content of the change indicated by the code (hereinafter referred to as "visual effect"). FIG. 4 is a diagram illustrating an example of the data structure of the visual effect table 112. The visual effect table 112 shown in FIG. 4 includes a code 112A and a visual effect 112B. The code 112A here is an example of a specific code included in a character string.

[0026] The code shown in FIG. 4 is defined by a combination of "!" and "alphanumeric characters." In this embodiment, "!" is a special symbol that indicates the start of the code. The special symbol may be "#," "&," "%," "*," or other symbols. Furthermore, the special symbol does not have to be a single character, and may be defined as a combination of multiple symbols that do not appear in natural language, such as "* / " or " / / / ." In this embodiment, the code is defined by one or more alphanumeric characters following "!". The alphanumeric characters of the code are defined as the part sandwiched between the special symbol and a space, comma, or the like.

[0027] The effect table 112 shown in FIG. 4 illustrates two types of codes. Specifically, it illustrates a code that specifies a "style" and a code that specifies a "movement." In the present embodiment, the style is assumed to be a character style, which is a collection of character formatting attributes. The character formatting includes, for example, font type, typeface (i.e., normal, italic, bold), font size, font color, character decoration, and character effects. However, the style may also include paragraph style. The classification of codes is not limited to "style" and "movement." Other classifications include, for example, adding sound effects. Another classification includes changing the brightness of character strings. Another classification includes codes that target the display area (hereinafter also referred to as "card") where character strings are displayed.

[0028] <Processing Executed by Functional Units> The following describes processing functions that the server 10 (see FIG. 2) realizes through the input receiving unit 101 (see FIG. 2) and the display control unit 102 (see FIG. 2). Note that detailed processing functions provided in each functional unit will be described in association with expected processing operation examples.

[0029] The input receiving unit 101 is a functional unit that receives input of a character string by the first user into an input area when an operation to post information to a viewing screen that displays information posted by multiple users including a first user and a second user is received from the first user. The users here correspond to user A and user B in FIG. 1. The first user is a user who inputs a message. The second user is a user to whom the message is addressed. Therefore, the users corresponding to the first user and the second user are determined for each message.

[0030] For example, when user A sends a message to user B, user A becomes the first user and user B becomes the second user. On the other hand, when user B sends a message to user A, user B becomes the first user and user A becomes the second user. Note that the viewing screen that displays information posted by users refers to the operation screen of a message app running on the user terminal 20.

[0031] As described above, the input accepting unit 101 in this embodiment is a function of the server 10 (see FIG. 1 ). Therefore, "accepting an operation to post information on a viewing screen that displays information posted by a user" means accepting a message from the user terminal 20. Note that "accepting input of a character string by a first user into an input area" also means accepting a message from the user terminal 20.

[0032] Furthermore, the display control unit 102 may add a sub-function that, when a posted character string includes a specific code (hereinafter referred to as the "specific code"), displays the portion of the posted character string excluding the specific code on the viewing screen in a display format corresponding to the specific code. FIG. 5 is a diagram illustrating an example of the structure of a posted character string. In the case of FIG. 5, the character string is "hello !b". The specific code is the "!b" portion, and the portion of the character string excluding the specific code is "hello".

[0033] In the case of FIG. 5, there is a space between the character string portion and the specific code. The portion separated by the space is recognized as a word portion or a code portion. Note that the space is an example of a separator. A comma, a period, a line break, a semicolon, or a colon may be used to separate the character string portion, for example. In this embodiment, one character string contains only one specific code, but it is also possible to include multiple specific codes, as in the embodiment described below.

[0034] The specific code "!b" shown in FIG. 5 means that the effect of displaying the "hello" part in bold is given. In this embodiment, the specific code "!b" can only be confirmed in the input area of ​​the first user. In other words, only the "hello" part is displayed on the viewing screen of the first user and the viewing screen of the second user. In the case of FIG. 5, the specific code is written at the end of the character string. However, in this embodiment, the display mode of the character string parts other than the specific code changes depending on whether the specific code is included in the character string, so the specific code may be written in a position other than the end. For example, the specific code may be written at the beginning of the sentence. In this case, it becomes "!b hello".

[0035] In this embodiment, the specific code is specified from a first code group including one or more codes that specify the style of the characters and a second code group including one or more codes that specify the movement of the characters. The first code group here corresponds to the codes in the right curly brackets labeled "style" in the performance effect table 112 (see FIG. 4). On the other hand, the second code group corresponds to the codes in the right curly brackets labeled "movement" in the performance effect table 112. Therefore, in this embodiment, it is assumed that the style or movement of a character string portion is specified by a specific code.

[0036] <Processing Operation> Fig. 6 is a diagram illustrating an example of the processing operation of the server 10 (see Fig. 1) in the first embodiment. The symbol S in the diagram indicates a step. The processing operation shown in Fig. 6 is initiated when the server 10 accepts a message posting from the user terminal 20 (see Fig. 1). First, the server 10 determines whether the message is a character string (step 101). If the message is an image, a negative result is obtained in step 101. In this case, the server 10 displays the posted image on the viewing screens of the sending and receiving users (step 102).

[0037] If the message is a character string, a positive result is obtained in step 101. In this case, the server 10 further determines whether the character string includes a specific code (step 103). The server 10 determines whether the character string includes a specific code by comparing the character string with the effect table 112 (see FIG. 2). The server 10 determines, for example, whether the character string includes a code 112A (see FIG. 4) registered in the effect table 112. If the character string does not include a specific code, a negative result is obtained in step 103. In this case, the server 10 displays the posted character string on the viewing screens of the sending and receiving users (step 104).

[0038] If the character string includes the specific code, a positive result is obtained in step 103. In this case, the server 10 displays the character string portion of the posted character string excluding the specific code on the viewing screens of the sending and receiving users, and applies a visual effect corresponding to the specific code (step 105). FIG. 7 is a diagram illustrating visual effects in the first embodiment. The left side of FIG. 7 shows message application screens 240A1 and 240A2 of a user terminal 20A operated by user A, who is the sender of the message. Meanwhile, the right side of FIG. 7 shows message application screens 240B1 and 240B2 of a user terminal 20B operated by user B, who is the recipient of the message. In the case of FIG. 7, user A is the first user, and user B is the second user.

[0039] 7 show the screens before user A posts a message, and message app screens 240A2 and 240B2 shown in the lower part show the screens after user A posts a message. On message app screens 240A1 and 240A2 displayed on user terminal 20A, the fact that the recipient of the message is user B is indicated by "<User B" in the upper left corner of the viewing screen 241A. On the other hand, on message app screens 240B1 and 240B2 displayed on user terminal 20B, the fact that the recipient of the message is user A is indicated by "<User A" in the upper left corner of the viewing screen 241B.

[0040] In the case of FIG. 7 , there are no messages exchanged between user A and user B. Therefore, both message application screens 240A1 and 240B1 shown in the upper part of FIG. 7 are blank. However, "hello! b" has been entered in the input field 242A of the message application screen 240A1 shown in the upper part of FIG. 7 . In addition, a "Post" button 243A is displayed to the right of the input field 242A of the message application screen 240A1. The "Post" button 243A is displayed when the message application detects a message input into the input field 242A. When user A operates the "Post" button 243A, the content of the message is confirmed. The message with the confirmed content is sent from the user terminal 20A to the server 10, addressed to user B. Incidentally, the "Post" button is not displayed on the message application screen 240B1 of user B, who is the message recipient, because the message application has not detected an input into the input field 242B.

[0041] Message application screens 240A2 and 240B2 shown in the lower part of Fig. 7 are displayed after the "Post" button 243A is operated. In the case of Fig. 7, the character string entered in input field 242A is "hello!b", so "hello" is displayed in bold in message field M of user A's viewing screen 240A2 and user B's viewing screen 240B2. Note that a message containing "hello" is displayed on the right side of user A's viewing screen 241A. This is because this message is a message posted by user A. On the other hand, a message containing "hello" is displayed on the left side of user B's viewing screen 241B. In the case of Fig. 7, an icon IC indicating that the message is from user A is displayed on the left side of message field M.

[0042] FIG. 8 is a diagram illustrating another effect according to the first embodiment. In FIG. 8, the parts corresponding to those in FIG. 7 are denoted by the same reference numerals. In the case of FIG. 8, "hello !s" is entered in input field 242A of message application screen 240A1. Here, "!s" is a code that instructs the character string portion to sway left and right. Therefore, on user A's viewing screen 240A2 and user B's viewing screen 240B2, "hello" in message field M is displayed in a manner that sways left and right. Note that the font of "hello" remains standard.

[0043] Summary: Information processing system 1 (see FIG. 1 ) according to the present embodiment employs a mechanism for, when a specific code is included in a posted message of a character string, displaying the character string portion on the viewing screen of a message application in a display mode corresponding to the specific code. Thus, by adding a desired specific code to the message of a character string, a user can freely change the display mode of the character string portion displayed on the viewing screen of the message application.

[0044] Specifically, the style and movement of the character string displayed on the viewing screen 241A (see FIG. 7) can be specified. In this embodiment, the specific code is a minimum of two characters that combines a special symbol and an alphanumeric character. This minimizes the impact on message posting. In addition, by changing the alphanumeric character combination, the display mode that can be specified can be changed.

[0045] Second Embodiment In the present embodiment, a description will be given of one form of the information processing system 1 (see FIG. 1) described in the first embodiment. Therefore, the present embodiment also assumes the system configuration and processing operation described in the first embodiment.

[0046] In this embodiment, one of the codes included in the first code group, which is a group of codes specifying the style of a character string portion, is referred to as the first code, and one of the codes included in the second code group, which is a group of codes specifying the movement of a character string portion, is referred to as the second code. In this case, the display control unit 102 (see FIG. 2 ) is provided with a sub-function that displays the character string portion in a display mode that combines the first display mode and the second display mode when the specific code includes the first code and the second code. That is, in this embodiment, an example of a processing function is described for a case where a posted character string includes both a specific code that specifies the style of the character string portion and a specific code that specifies the movement of the character string portion. The first display mode is the display mode specified by the first code. The second display mode is the display mode specified by the second code.

[0047] FIG. 9 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the second embodiment. In FIG. 9, parts corresponding to those in FIG. 6 are assigned reference numerals. Note that the example of processing operations shown in FIG. 9 assumes a case where a character string contains one or two specific codes. Furthermore, the two specific codes contained in the character string are limited to a combination of a specific code that indicates the style of a character string portion and a specific code that indicates the movement of the character string portion. In other words, this embodiment does not assume a case where two specific codes that indicate the style of a character string portion or two specific codes that indicate the movement of a character string portion are included.

[0048] In the example of processing operation shown in FIG. 9, after a positive result is obtained in step 103, the server 10 (see FIG. 1) determines whether or not the text contains both a specific code (style) and a specific code (movement) (step 111). Here, "specific code (style)" refers to a specific code that specifies the style of a character string portion. This "specific code (style)" is an example of a first code. Also, "specific code (movement)" refers to a specific code that specifies the movement of a character string portion. This "specific code (movement)" is an example of a second code.

[0049] If the specific code contained in the character string is only "specific code (style)" or only "specific code (movement)", a negative result is obtained in step 111. In this case, the server 10 executes step 105, as in the first embodiment. On the other hand, if the character string contains multiple specific codes, and these are a combination of specific codes that specify the style of the character string portion and specific codes that specify the movement of the character string portion, a positive result is obtained in step 111. In this case, the server 10 displays the character string portion of the posted character string excluding the specific code on the viewing screens of the sending and receiving users, and applies a dramatic effect that combines the two specific codes (step 112).

[0050] FIG. 10 is a diagram illustrating the effect of the second embodiment. In FIG. 10, the parts corresponding to those in FIG. 7 are denoted by the same reference numerals. In the case of FIG. 10, "hello!b!s" is entered in input field 242A of message application screen 240A1. Here, "!b" is a code instructing the display of the character string portion in bold, and "!s" is a code instructing the character string portion to oscillate left and right. Therefore, on user A's viewing screen 240A2 and user B's viewing screen 240B2, "hello" displayed in bold in message field M is displayed in a manner that oscillates left and right. In the case of FIG. 10, the bold display is a first display mode, and the oscillating display is a second display mode.

[0051] <Summary> In the information processing system 1 (see FIG. 1) according to this embodiment, when a posted message of a character string includes both a specific code that indicates the style of the character string portion and a specific code that indicates the movement of the character string portion, the character string portion can be displayed in a display mode corresponding to each of the specific codes.

[0052] Third Embodiment In this embodiment, a description will be given of one form of the information processing system 1 (see FIG. 1) described in the first embodiment. Therefore, this embodiment also assumes the system configuration and processing operation described in the first embodiment.

[0053] In this embodiment, one of the codes included in the second code group, which is a collection of codes specifying the movement of a character string portion, is referred to as the second code, and the other code is referred to as the third code. The second code and the third code both specify the movement of a character string portion, but the instructions are different. In this case, the display control unit 102 (see FIG. 2 ) is added with a sub-function that, when the specific code includes the second code and the third code, displays the character string portion in a display mode that sequentially switches between the second display mode and the third display mode. That is, in this embodiment, an example of a processing function when a posted character string includes two specific codes specifying the movement of a character string portion will be described. The second display mode is the display mode specified by the second code. The third display mode is the display mode specified by the third code.

[0054] FIG. 11 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the third embodiment. In FIG. 11, parts corresponding to those in FIG. 6 are assigned the same reference numerals. Note that the example of processing operations shown in FIG. 11 assumes that a character string contains one or two specific codes. Furthermore, the two specific codes contained in the character string are limited to combinations of two specific codes that instruct the movement of a portion of the character string. In other words, the combinations of specific codes described in the second embodiment are not assumed in this embodiment.

[0055] In the processing operation example shown in FIG. 11, after a positive result is obtained in step 103, the server 10 (see FIG. 1) determines whether or not both a specific code (movement 1) and a specific code (movement 2) are included (step 121). Here, "specific code (movement 1)" refers to the first specific code that specifies the movement of the character string portion. This "specific code (movement 1)" is an example of the second code mentioned above. "specific code (movement 2)" refers to the second specific code that specifies the movement of the character string portion. This "specific code (movement 2)" is an example of the third code mentioned above.

[0056] If the specific code contained in the character string is only "specific code (style)" or only "specific code (movement)", a negative result is obtained in step 121. In this case, the server 10 executes step 105, as in embodiment 1. On the other hand, if the character string contains two specific codes that specify the movement of the character string portion, a positive result is obtained in step 121. In this case, the server 10 displays the character string portion of the posted character string excluding the specific codes on the viewing screens of the sending and receiving users, and applies the dramatic effects corresponding to each specific code in turn (step 122).

[0057] FIG. 12 is a diagram illustrating a dramatic effect in the third embodiment. In FIG. 12, parts corresponding to those in FIG. 7 are denoted by the same reference numerals. In the case of FIG. 12, a message application screen 240A1 of a user terminal 20A operated by a user A and a message application screen 240B1 of a user terminal 20B operated by a user B are displayed in three rows: an upper row, a middle row, and a lower row. Time progresses from the upper row to the lower row. In the case of FIG. 12, "hello!s!h" is entered in the input field 242A of the message application screen 240A1. Here, "!s" is a code that instructs the character string portion to sway left and right, and "!h" is a code that instructs the character string portion to sway up and down.

[0058] In this embodiment, the two specific codes included in the character string are executed in the order in which they are written. That is, as shown in the middle of FIG. 12, on user A's viewing screen 240A2 and user B's viewing screen 240B2, "hello" in message field M is displayed in a manner that oscillates from side to side. In the case of FIG. 12, the display that oscillates from side to side is the second display mode. Next, as shown in the bottom of FIG. 12, on user A's viewing screen 240A2 and user B's viewing screen 240B2, "hello" in message field M is displayed in a manner that oscillates up and down. In the case of FIG. 12, the display that oscillates up and down is the third display mode.

[0059] In this embodiment, the switch from the second display mode to the third display mode is executed after a time determined by the system has elapsed since the start of display in the second display mode. For example, if the display in the second display mode continues for three seconds, the display in the second display mode is switched to the display in the third display mode. This display mode in which "hello" oscillates up and down also continues for the time determined by the system. After the time determined by the system has elapsed, the display mode is switched to the same as that of a character string without a specific code. In other words, "hello" is displayed without oscillating.

[0060] In the information processing system 1 according to the present embodiment (see FIG. 1 ), when a posted message of a character string includes multiple specific codes that instruct the movement of the character string portion, the character string portion can be displayed in a display mode in which the movements corresponding to the specific codes are switched in sequence. Note that while FIGS. 11 and 12 are based on the case where the character string includes two specific codes that instruct the movement of the character string portion, when the character string includes three or more specific codes that instruct the movement of the character string portion, it is sufficient to switch the display modes corresponding to the specific codes in sequence.

[0061] <Embodiment 4> In this embodiment, a configuration of the information processing system 1 (see FIG. 1) described in embodiment 3 will be described. Therefore, this embodiment also assumes the system configuration and processing operation described in embodiment 3. In this embodiment, a sub-function is added to the display control unit 102 (see FIG. 2) that controls switching between the second display mode and the third display mode based on the display time of the second code and the display time of the third code when the specific code includes information specifying the display time of the second code and the display time of the third code.

[0062] FIG. 13 is a flowchart illustrating an example of processing operations including processing corresponding to the subfunctions described in the fourth embodiment. In FIG. 13, the same reference numerals are used to denote the corresponding parts in FIG. 11 . In the example of processing operations shown in FIG. 13, after a positive result is obtained in step 121, the server 10 (see FIG. 1) determines whether the specific code specifies a display time (step 123). In this embodiment, a rule is adopted in which the specific code is followed by the length of time for which the display mode is desired to continue. Examples of such a rule include a method in which the specific code is followed by the display time in parentheses, a method in which the specific code is followed by an underscore and the display time, or a method in which a half-width space is inserted after the specific code and then the display time is written.

[0063] If no notation specifying the display time appears following the specific code included in the character string, a negative result is obtained in step 123. In this case, the server 10 executes step 122, as in the third embodiment. That is, after the time set by the system has elapsed, the second display mode is switched to the third display mode. On the other hand, if a notation specifying the display time appears following the specific code included in the character string, a positive result is obtained in step 123. In this case, the server 10 displays the part of the posted character string excluding the specific code on the viewing screens of the sending and receiving users, and switches the visual effect corresponding to each specific code at the specified time (step 124).

[0064] FIG. 14 is a diagram illustrating the effect of the fourth embodiment. In FIG. 14, the parts corresponding to those in FIG. 12 are denoted by the same reference numerals. In the case of FIG. 14, similar to FIG. 12, a message application screen 240A1 of the user terminal 20A operated by user A and a message application screen 240B1 of the user terminal 20B operated by user B are displayed in three rows: an upper row, a middle row, and a lower row. In the case of FIG. 14, "hello! s (1 s)! h (0.5 s)" is entered in the input field 242A of the message application screen 240A1. Here, "(1 s)" means output for 1 second in the corresponding display mode, and "0.5 s" means output for 0.5 seconds in the corresponding display mode. Note that in the method of specifying the time length, only numerical notation may be permitted. For example, notation such as "(1)" or "0.5" may be permitted.

[0065] In the present embodiment, viewing screens 240A2 and 240B2 shown in the middle of FIG. 12 display "hello" in message field M for one second in a display mode that oscillates from side to side. This display time is the time specified by user A who posted the message. Next, viewing screens 240A2 and 240B2 shown in the bottom of FIG. 12 display "hello" in message field M for 0.5 seconds in a display mode that oscillates up and down. This display time is also the time specified by user A who posted the message. Note that when the display mode in which "hello" oscillates up and down continues for 0.5 seconds, "hello" switches to a display mode in which it does not oscillate.

[0066] <Summary> In the information processing system 1 (see FIG. 1 ) according to the present embodiment, when a posted message of character strings includes a specific code that indicates the movement of the character string portion and that is accompanied by display time information, the display time can be controlled for each movement specified by the specific code. As a result, the display mode on the viewing screens 241A and 241B of the message app can be controlled as intended by the user posting the message. In the present embodiment as well, when a message includes three or more specific codes that indicate the movement of the character string portion, the display mode can be switched in sequence for each time period specified for each specific code.

[0067] In this embodiment, the case where the display time is specified for all of the multiple specific codes included in the character string has been described, but the character string may include specific codes for which no display time is specified. For example, if the character string is "hello! s! h (0.5 s)", "hello" will be oscillated left and right for the time set by the system, and then will switch to oscillating up and down for 0.5 seconds.

[0068] Fifth Embodiment This embodiment also describes one form of the information processing system 1 (see FIG. 1) described in the third embodiment. Therefore, this embodiment also assumes the system configuration and processing operation described in the third embodiment.

[0069] In this embodiment, the display control unit 102 (see FIG. 2) is provided with a sub-function that executes display in the second display mode after display in the third display mode when the second code is written first and the third code is written last in the specific code, and executes display in the third display mode after display in the second display mode when the third code is written first and the second code is written last in the specific code. That is, in this embodiment, a case will be described in which the display mode is switched in accordance with the order in which the specific codes are written in the character string.

[0070] 15 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the fifth embodiment. In FIG. 15, the parts corresponding to those in FIG. 11 are denoted by the same reference numerals. In the example of processing operations shown in FIG. 15, after a positive result is obtained in step 121, the server 10 (see FIG. 1) determines whether the specific code (movement 1) is written before the specific code (movement 2) (step 125). That is, the server 10 checks the order in which the two specific codes defining the movements are written.

[0071] If the specific code (movement 2) is written before the specific code (movement 1), a negative result is obtained in step 125. In this case, the server 10 displays the portion of the posted character string excluding the specific code on the viewing screens of the users on the sending and receiving sides, and applies the effect of the specific code (movement 1) after the effect of the specific code (movement 2) (step 126). On the other hand, if the specific code (movement 1) is written before the specific code (movement 2), a positive result is obtained in step 125. In this case, the server 10 displays the portion of the posted character string excluding the specific code on the viewing screens of the users on the sending and receiving sides, and applies the effect of the specific code (movement 2) after the effect of the specific code (movement 1) (step 127).

[0072] FIG. 16 is a diagram illustrating the effect of the fifth embodiment. In FIG. 16, the parts corresponding to those in FIG. 12 are denoted by the corresponding reference numerals. In FIG. 16, in order to illustrate the difference in the order in which the display modes appear due to the difference in the order in which specific codes are written in the character string, both the screen transition examples in the left column and the screen transition examples in the right column of FIG. 16 correspond to the user terminal 20A. The screen transitions of the user terminal 20B are the same as those in FIG. 16 except for the upper row. In FIG. 16, "hello! s! h" is entered in the input field 242A of the message application screen 240A1 shown in the left column. Meanwhile, "hello! h! s" is entered in the input field 242A of the message application screen 240A1 shown in the right column.

[0073] For this reason, in viewing screen 240A2 shown in the middle left column, "hello" in message field M is displayed in a display mode that sways left and right, whereas in viewing screen 240A2 shown in the middle right column, "hello" in message field M is displayed in a display mode that sways up and down. Note that in viewing screen 240A2 shown in the bottom left column, "hello" in message field M is displayed in a display mode that sways up and down, whereas in viewing screen 240A2 shown in the bottom right column, "hello" in message field M is displayed in a display mode that sways left and right. In this way, in this embodiment, the display mode of the character string portion displayed on viewing screen 241A transitions in the order of the specific codes in the character string.

[0074] <Summary> In the information processing system 1 (see FIG. 1 ) according to the present embodiment, when a posted message of character strings contains multiple specific codes that instruct the movement of portions of the character string, the order in which the display modes appear can be controlled by the order in which the specific codes are written in the character string. As a result, the display modes on the viewing screens 214A and 214B of the message app can be controlled as intended by the user who posts the message. In the present embodiment as well, when a message contains three or more specific codes that instruct the movement of portions of the character string, the display modes can be switched in the order in which the three or more specific codes are written.

[0075] Sixth Embodiment In this embodiment, a form of the information processing system 1 (see FIG. 1) described in Embodiment 1 will be described. Therefore, this embodiment also assumes the system configuration and processing operation described in Embodiment 1. In this embodiment, the input receiving unit 101 (see FIG. 2) is added with a sub-function that warns of an invalid code before posting if the combination of a special symbol and an alphanumeric character is not included in the performance effect table 112 (see FIG. 2).

[0076] 17 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the sixth embodiment. The processing operations shown in FIG. 17 are also initiated when the server 10 receives a message posting from the user terminal 20 (see FIG. 1). First, the server 10 determines whether the message being input is a character string (step 131). If the message is an image, a negative result is obtained in step 131. In this case, the server 10 permits notification of the message to the destination (step 132). In this case, the server 10 initiates the processing operations described in the first to fifth embodiments, for example.

[0077] On the other hand, if the message is a character string, a positive result is obtained in step 131. In this case, the server 10 determines whether the character string includes a combination of special symbols and alphanumeric characters (step 133). In this embodiment, a combination of special symbols and alphanumeric characters is considered to be a description that may be a specific code. If a combination of special symbols and alphanumeric characters is not included, a negative result is obtained in step 133. In this case, the server 10 proceeds to step 132. That is, the server 10 allows notification of the message to the destination. If the message includes a combination of special symbols and alphanumeric characters, a positive result is obtained in step 133. In this case, the server 10 further determines whether the combination of special symbols and alphanumeric characters is included in the effect table 112 (see FIG. 2) (step 134).

[0078] If the combination of the special symbol and alphanumeric characters is in the effect effect table 112, i.e., if it is a specific code, a positive result is obtained in step 134. In this case, the server 10 proceeds to step 132. That is, the server 10 allows notification of the message to the destination. On the other hand, if the combination of the special symbol and alphanumeric characters is in the effect effect table 112, i.e., if it is similar to a specific code but is not a specific code, a negative result is obtained in step 134. In this case, the server 10 notifies the user that the specific code is incorrect (step 135).

[0079] FIG. 18 is a diagram illustrating an example of an error message output in the sixth embodiment. In FIG. 18, the parts corresponding to those in FIG. 7 are assigned the same reference numerals. FIG. 18 shows only the message application screen of the user terminal 20A operated by user A. The message application screen 240A1 shown in the upper row is an example of the screen before the "Post" button 243A is operated. In other words, it is an example of the screen while a message character string is being entered. The message application screen 240A3 shown in the lower row is an example of the screen after the "Post" button 243A is operated.

[0080] "hello !z" is entered in the input field 242A of the message application screen 240A1 shown in the upper part of FIG. 18. In the case of FIG. 18, "!z" does not exist in the effect table 112 (see FIG. 2). In this case, the server 10 can notify user B of "hello !z" as a message that does not include a specific code. However, "!z" satisfies the description rules for specific codes. Therefore, the server 10 assumes that user A intends to instruct some kind of display mode and issues a warning. Specifically, an error message 244 is displayed as a pop-up on the message application screen 240A3 shown in the lower part of FIG. 18.

[0081] In the case of Fig. 18, the error message 244 displays "Error", "!z is an invalid code", and "Please re-enter the correct code". Of course, these displays are merely examples. Note that the error message 244 shown in Fig. 18 may also display one or more correct codes.

[0082] <Summary> In information processing system 1 according to the present embodiment (see FIG. 1), it is possible to prompt the user to confirm the input character string before a message that is likely intended to instruct a display mode is notified to the user as the destination. Note that without the function of the present embodiment, a message that is different from the intended display mode, such as "hello!z," would be displayed as is on viewing screens 241A and 241B.

[0083] Seventh Embodiment In this embodiment, a description will be given of one form of the information processing system 1 (see FIG. 1) described in Embodiment 1. Therefore, this embodiment also assumes the system configuration and processing operation described in Embodiment 1. The input receiving unit 101 (see FIG. 2) in this embodiment adds a sub-function that, if a specific code includes a first code and a fourth code that is prohibited from being combined with the first code, warns the user before posting that the combination is invalid.

[0084] FIG. 19 is a diagram illustrating an example of the functional configuration of the server 10 in the seventh embodiment. In FIG. 19, parts corresponding to those in FIG. 2 are denoted by the same reference numerals. In the case of FIG. 19, a prohibition table 113 is added to the storage unit 110. The prohibition table 113 is a table listing invalid combinations of specific codes. An example of an invalid combination is a combination in which instructions are contradictory.

[0085] Fig. 20 is a diagram illustrating an example of the data structure of the prohibition table 113. The prohibition table 113 shown in Fig. 20 includes a combination 113A and an explanation 113B. The prohibition table 113 shown in Fig. 20 illustrates examples of combinations of two styles and two movements. For example, the example illustrates a case where two styles are combined to simultaneously display a character string portion in 8-point font and a character string portion in 11-point font.

[0086] For example, a combination of two movements is illustrated in which a fade-in display and a fade-out display of a character string are simultaneously specified. The prohibition table 113 shown in Figure 20 is based on the premise that when a character string contains multiple specific codes, the display modes corresponding to all the specific codes are applied simultaneously. Note that, unlike this embodiment, the above-mentioned third and fifth embodiments are based on the premise that when a character string contains multiple specific codes, the corresponding display modes are switched in sequence.

[0087] FIG. 21 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the seventh embodiment. In FIG. 21, parts corresponding to those in FIG. 17 are assigned reference numerals. The processing operations illustrated in FIG. 21 are also initiated when the server 10 (see FIG. 1) accepts a message posting from the user terminal 20 (see FIG. 1). In the example of processing operations illustrated in FIG. 21, after a positive result is obtained in step 131, the server 10 determines whether the character string contains a specific code (step 141). If the character string does not contain the specific code, a negative result is obtained in step 141. In this case, the server 10 proceeds to step 132 and permits notification of the message to the destination.

[0088] On the other hand, if the character string includes a specific code, the server 10 further determines whether the character string includes multiple specific codes (step 142). If the character string includes one specific code, a negative result is obtained in step 142. In this case, the server 10 proceeds to step 132. On the other hand, if the character string includes multiple specific codes, a positive result is obtained in step 142. In this case, the server 10 further determines whether the combination of specific codes is prohibited (step 143). If the combination of specific codes is not prohibited, a negative result is obtained in step 143. In this case, the server 10 proceeds to step 132. On the other hand, if the combination of specific codes is prohibited, a positive result is obtained in step 143. In this case, the server 10 notifies the user that the combination of specific codes is incorrect (step 144).

[0089] FIG. 22 is a diagram illustrating an example of an error message output in the seventh embodiment. In FIG. 22, the parts corresponding to those in FIG. 7 are denoted by the same reference numerals. In the case of FIG. 22, only the message application screen of the user terminal 20A operated by user A is illustrated. The message application screen 240A1 shown in the upper part is an example of the screen before the "Post" button 243A is operated. That is, it is an example of the screen while a character string message is being input. The message application screen 240A4 shown in the lower part is an example of the screen after the "Post" button 243A is operated. "hello!c:red!c:blue" has been input in the input field 242A of the message application screen 240A1 shown in the upper part of FIG. 22. In the case of FIG. 22, "!c:red!c:blue" is registered in the prohibition table 113 (see FIG. 20). Therefore, the server 10 notifies that user A has specified a combination that falls under the prohibition rule. Specifically, an error message 245 is displayed as a pop-up on a message application screen 240A1 shown in the lower part of FIG.

[0090] In the example of Fig. 22, the error message 245 displays "Error," "hello!c:red!c:blue is an invalid combination," and "Please check your code combination." Of course, these displays are merely examples. The error message 245 shown in Fig. 22 may also display one or more examples of correct code combinations.

[0091] <Summary> In the information processing system 1 (see FIG. 1) according to this embodiment, it is possible to prompt the user to confirm the character strings they have entered before a message containing an invalid combination is notified to the user as a destination. In other words, it is possible to prevent the posting of a message containing a specific code of an invalid combination. Note that without the function of this embodiment, a message that differs from the intended display format, for example, "hello! c:red! c:blue," would be displayed as is on the viewing screens 241A and 241B.

[0092] Eighth Embodiment In this embodiment, one form of the information processing system 1 (see FIG. 1) described in the first embodiment will be described. Therefore, this embodiment also assumes the system configuration and processing operation described in the first embodiment. In this embodiment, the input acceptance unit 101 (see FIG. 2) is added with a sub-function that, when a first code is input, presents other codes that can be combined with the first code as specific codes. Note that the input acceptance unit 101 may further be added with a sub-function that shows examples of display modes for each of the other codes when combined with the first code.

[0093] FIG. 23 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the eighth embodiment. In FIG. 23, the same reference numerals are used to denote parts corresponding to those in FIG. 21 . The processing operations shown in FIG. 23 are also initiated when the server 10 accepts a message posting from the user terminal 20 (see FIG. 1 ). In the example of processing operations shown in FIG. 23 , after a positive result is obtained in step 141, the server 10 (see FIG. 1 ) determines whether there are other specific codes that can be combined (step 151). If there are no other specific codes that can be combined, a negative result is obtained in step 151. In this case, the server 10 proceeds to step 132 and permits notification of the message to the destination.

[0094] On the other hand, if there are other specific codes that can be combined, a positive result is obtained in step 151. In this case, the server 10 presents candidates for other specific codes that can be combined with examples of display modes (step 152). That is, the server 10 displays a preview of the display mode when other specific codes are combined for each candidate. Next, the server 10 determines whether any of the candidates has been selected (step 153).

[0095] If none of the candidates is selected, a negative result is obtained in step 153. For example, if the user instructs to post a message using the current character string, a negative result is obtained in step 153. In this case, the server 10 moves to step 132. On the other hand, if any of the candidates is selected, a positive result is obtained in step 153. In this case, the server 10 updates the character string (step 154) and moves to step 132.

[0096] FIG. 24 is a diagram illustrating an example of a presentation of specific codes that can be combined in embodiment 8. In FIG. 24, the parts corresponding to those in FIG. 7 are assigned the same reference numerals. In the case of FIG. 24, only the message application screen of the user terminal 20A operated by user A is shown. The message application screen 240A1 shown in the upper row is an example of the screen before the "Post" button 243A is operated. In other words, it is an example of the screen while a message character string is being entered. The message application screen 240A5 shown in the lower row is an example of the screen after the "Post" button 243A is operated.

[0097] "hello!b" has been entered in input field 242A of message application screen 240A1 shown in the upper part of Fig. 24. The specific code here indicates that the character string portion should be displayed in bold. In message application screen 240A5 shown in the lower part of Fig. 24, a speech bubble 246 is displayed following the specific code (i.e., "!b") that has already been entered. In speech bubble 246 shown in Fig. 24, an explanatory text 246A reads, "The following codes can be combined."

[0098] In the example shown in Fig. 24, a candidate column 246B is displayed below the explanatory text 246A. The candidate column 246B shown in Fig. 24 displays three candidates for other specific codes that can be combined. Specifically, "!s", "!h", and "!r" are displayed as candidates for other specific codes that can be combined. To the right of each candidate, a preview of how the specific code entered by the user will appear when combined with each candidate is displayed.

[0099] For example, to the right of "!s" is a preview of a bold "hello" that sways from side to side. Similarly, to the right of "!h" is a preview of a bold "hello" that sways up and down. Similarly, to the right of "!r" is a preview of a bold "hello" that rotates clockwise.

[0100] Additionally, a "Select" button 246C is displayed to the right of the candidate column 246B, corresponding to each candidate. When any of the "Select" buttons 246C is operated, the message is updated to include the corresponding specific code. For example, when the "Select" button 246C corresponding to "!s" is operated, the server 10 (see FIG. 1) updates user A's message to "hello !b!s." As a result, "hello" appears in bold, oscillating from side to side, on the message application screen 240A2 and the message application screen 240B2 (see FIG. 7). A skip button 246D, provided for cases in which no other specific code candidate is selected, is displayed near the bottom of the speech bubble 246 shown in FIG. 24. In FIG. 24, the skip button 246D is labeled "Post with current content." When the skip button 246D is operated, the server 10 displays "hello" in bold on the message application screen 240A2, the message application screen 240B2 (see FIG. 7), and the like.

[0101] Summary: The information processing system 1 (see FIG. 1 ) according to this embodiment employs a mechanism for presenting candidates for other specific codes that can be combined with a specific code included in a message. This allows the user to specifically know the other specific codes that can be combined with the specific code that the user has specified. As a result, the system can assist the user in inputting a message. Furthermore, in the case of the information processing system 1 described in this embodiment, a preview of the display state when the other specific codes are combined is displayed, making it easy to visualize whether or not to add the other specific code. However, it is also possible to present only candidates for other specific codes that can be combined without displaying a preview. Furthermore, in the example screen shown in FIG. 24 , the message is updated by operating the selection button 246C, but the addition of another specific code may also be accepted through a user input in the input field 242A.

[0102] Ninth Embodiment In this embodiment, a configuration of the information processing system 1 (see FIG. 1) described in the first embodiment will be described. Therefore, this embodiment also assumes the system configuration and processing operation described in the first embodiment. A sub-function of presenting candidates for a specific chord selected based on a character string portion is added to the input receiving unit 101 (see FIG. 2) in this embodiment.

[0103] FIG. 25 is a diagram illustrating an example of the functional configuration of the server 10 in the ninth embodiment. In FIG. 25, the parts corresponding to those in FIG. 2 are denoted by the same reference numerals. In the case of FIG. 25, a recommended code table 114 is added to the storage unit 110. The recommended code table 114 is a table that associates specific character expressions with specific codes. The specific character expressions include, for example, expressions related to emotions or feelings, expressions related to greetings, expressions pre-registered by a messaging app, and expressions registered by the user. The specific expression may be a specific single character, a specific word, an exclamation, or a phrase combining specific symbols such as an exclamation mark or a question mark.

[0104] Fig. 26 is a diagram illustrating an example of the data structure of the recommended code table 114. The recommended code table 114 shown in Fig. 26 includes an expression 114A and a recommended candidate 114B. In the recommended code table 114 shown in Fig. 26, multiple specific code candidates are registered for each expression consisting of one or multiple words. However, the recommended code table 114 may also register one specific code candidate for each expression.

[0105] FIG. 27 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the ninth embodiment. In FIG. 27, the same reference numerals are used to denote parts corresponding to those in FIG. 17. The processing operations shown in FIG. 27 are also initiated when the server 10 (see FIG. 1) accepts a message post from the user terminal 20 (see FIG. 1). In the example of processing operations shown in FIG. 27, after a positive result is obtained in step 131, the server 10 determines whether there are any candidates for specific codes that can be combined with the character string being input (step 161). Specifically, the server 10 determines whether the target character string includes an expression 114A registered in the recommended code table 114.

[0106] If there is no specific code that can be combined, a negative result is obtained in step 161. In this case, the server 10 proceeds to step 132 and allows notification of the message to the destination. On the other hand, if there is a specific code that can be combined, the server 10 presents candidates for specific codes that can be combined (step 162). Next, the server 10 determines whether any of the candidates has been selected (step 163).

[0107] If none of the candidates is selected, a negative result is obtained in step 163. For example, if the user instructs to post a message using the current character string, a negative result is obtained in step 163. In this case, the server 10 moves to step 132. On the other hand, if any of the candidates is selected, a positive result is obtained in step 163. In this case, the server 10 updates the character string (step 164) and moves to step 132.

[0108] FIG. 28 is a diagram illustrating an example of a presentation of a specific code recommended for a character string including a specific expression in the ninth embodiment. In FIG. 28, the parts corresponding to those in FIG. 7 are assigned the same reference numerals. In the case of FIG. 28, only the message application screen of the user terminal 20A operated by user A is shown. The message application screen 240A1 shown in the upper part is an example of the screen before the "Post" button 243A is operated. In other words, it is an example of the screen while a message character string is being entered. The message application screen 240A6 shown in the lower part is an example of the screen after the "Post" button 243A is operated.

[0109] "Hello" has been entered in input field 242A of message application screen 240A1 shown in the upper part of Fig. 28. Incidentally, "hello" is an expression registered in recommended chord table 114. In message application screen 240A6 shown in the lower part of Fig. 28, a speech bubble 247 is displayed following the character string that is the target of recommendation (i.e., "hello"). In speech bubble 247 shown in Fig. 28, "The following chords can be combined" is displayed as explanatory text 247A.

[0110] In the case of FIG. 28 , a candidate column 247B is displayed below the explanation 247A. The candidate column 247B shown in FIG. 28 displays five candidates for specific codes that can be combined. Specifically, "!b", "!B", "!i", "!c:*", and "!FS:*p" are displayed as candidates for specific codes that can be combined. The meaning of the specific code is displayed to the right of each candidate. For example, "bold" is displayed to the right of "!b", and "bold capital letters" is displayed to the right of "!B". Note that instead of the meaning of the specific code, a preview of the display mode that will be achieved by combining the specific code with the specific code may be displayed to the right of each candidate.

[0111] Additionally, "Select" buttons 247C are displayed to the right of the candidate column 247B in association with each candidate. When any of the "Select" buttons 247C is operated, the message is updated to include the corresponding specific code. For example, when the "Select" button 247C corresponding to "!b" is operated, the server 10 (see FIG. 1) updates the user A's message to "hello !b." As a result, "hello" is displayed in bold on the message application screen 240A2 and the message application screen 240B2 (see FIG. 7), etc.

[0112] 28, a skip button 247D is displayed near the bottom of the speech bubble 247 in case the presented specific code is not selected. In the case of FIG. 28, the skip button 247D is labeled "Post with current content." When this skip button 247D is operated, the server 10 displays "hello" in standard typeface on the message application screen 240A2 and the message application screen 240B2 (see FIG. 7), etc.

[0113] <Summary> The information processing system 1 (see FIG. 1) according to this embodiment employs a mechanism for presenting candidate specific codes that can be combined when a specific expression is included in a message. This allows the user to specifically know candidate specific codes that are effective in enhancing the character string portion that the user has entered. As a result, it is possible to assist the user in inputting a message. In the example screen shown in FIG. 28, the message is updated by operating the selection button 247C, but the addition of a specific code may also be accepted through a user input in the input field 242A.

[0114] In this embodiment, a recommended chord table 114 (see FIG. 25) is stored in the storage unit 110 (see FIG. 25) and specific chord candidates that have been registered in advance for specific expressions are presented, but a trained model may be stored instead of the recommended chord table 114. FIG. 29 is a diagram illustrating another example of the functional configuration of the server 10 in embodiment 9. In FIG. 29, parts corresponding to those in FIG. 2 are assigned the same reference numerals. In the case of FIG. 29, a recommended chord trained model 115 is added to the storage unit 110.

[0115] The recommended code learned model 115 includes a model that has been machine-learned to learn the relationship between, for example, a character string as input and a recommended specific code as output. When this type of learned model is used, even before the "Post" button 243A (see FIG. 28) of the message is pressed, the character string being input can be input into the learned model, making it possible to recommend a specific code suitable for the character string being input.

[0116] Another example of the recommended code learned model 115 is a model that has been machine-learned to learn the relationship between, for example, a character string as input and a character string with a recommended specific code inserted as output. When this type of learned model is used, by inputting the character string being input into the learned model, it becomes possible to present to the user candidate character strings with specific codes inserted that are suitable for the character string being input.

[0117] Tenth Embodiment In this embodiment, a form of the information processing system 1 (see FIG. 1) described in the first embodiment will be described. Therefore, this embodiment also assumes the system configuration and processing operation described in the first embodiment. In this embodiment, a sub-function is added to the display control unit 102 (see FIG. 2) to apply, when a specific code in a character string corresponding to a new post is information that identifies the post on the viewing screen, the display mode of the post identified by the information to the display of the new post.

[0118] First, information for identifying a post on the viewing screen will be described. In this embodiment, the position of a new post is used as a reference position, and other posted messages are identified as the one before, the one before, etc. Fig. 30 is a diagram for explaining the identification of a position without distinguishing between the user and others. In Fig. 30, parts corresponding to those in Fig. 8 are assigned the same reference numerals. In Fig. 30, only the message app screen of the user terminal 20A operated by user A is shown.

[0119] Incidentally, the message immediately before contains a specific code that causes the text to swing left and right. The message two messages before contains a specific code that causes the text to swing up and down. The message four messages before contains a specific code that causes the text to be displayed in bold.

[0120] 31 is a diagram illustrating the identification of positions for distinguishing between oneself and others. In FIG. 31, the parts corresponding to those in FIG. 30 are denoted by the same reference numerals. For example, the two messages located on the left side of viewing screen 241A are identified as the previous message and the message two messages before that from user B. On the other hand, the three messages located on the right side of viewing screen 241A are identified as the previous message, the message two messages before, and the message three messages before that from user A.

[0121] FIG. 32 is a diagram illustrating an example of a description of a specific code including information for identifying a post on the viewing screen. In FIG. 32, the corresponding parts to those in FIG. 4 are assigned the same reference numerals. The content portion of the effect table 112 shown in FIG. 32 is, for example, an additional portion of the effect table 112 shown in FIG. 4. "!-1", "!-2", "!-3", etc. are application codes for effect corresponding to the location identification method described in FIG. 30. "!-1@user*", "!-2@user*", "!-3@user*", etc. are application codes for effect corresponding to the location identification method described in FIG. 31. Information for identifying user A or user B is entered in the "user*" portion. For example, the user's account name is entered.

[0122] FIG. 33 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in the tenth embodiment. In FIG. 33, parts corresponding to those in FIG. 6 are denoted by the same reference numerals. The processing operations illustrated in FIG. 33 are also initiated when the server 10 (see FIG. 1) accepts a message post from the user terminal 20 (see FIG. 1). In the example of processing operations illustrated in FIG. 33, after a positive result is obtained in step 103, the server 10 further determines whether the specific code indicates the application of a special effect for the specific message (step 171). If the specific code does not indicate the application of a special effect for the specific message, a negative result is obtained in step 171. In this case, the server 10 proceeds to step 105. On the other hand, if the specific code indicates the application of a special effect for the specific message, a positive result is obtained in step 171. In this case, the server 10 reads out the specific code described in the identified message and replaces the current code with the specific code (step 172).

[0123] FIG. 34 is a diagram illustrating an example of a message input in the tenth embodiment and the display state of the message after posting. In FIG. 34, the same reference numerals are used to denote parts corresponding to those in FIG. 30. In the case of FIG. 34, only the message application screen of the user terminal 20A operated by user A is shown. In the case of FIG. 34, "That's good!-2" is entered in the input field 242A of the upper viewing screen 241A. The character string portion of this message is "That's good" and the specific code is "!-2".

[0124] As explained in the effect table 112 of FIG. 32 , the specific code "!-2" is information that specifies the message two messages ago. The message two messages ago, "How have you been?", is displayed in a manner that oscillates up and down. In other words, the message two messages ago contains the specific code "!h." Therefore, after the "Post" button 243A is operated, the lower viewing screen 241A displays "That's good" as User A's message in a manner that oscillates up and down.

[0125] FIG. 35 is a diagram illustrating an example of a message input in embodiment 10 and another example of the display mode of the message after posting. In FIG. 35, the same reference numerals are used to denote parts corresponding to those in FIG. 30. In the case of FIG. 35, only the message application screen of user terminal 20A operated by user A is shown. In the case of FIG. 35, "That's good!-3@userA" is entered in input field 242A of viewing screen 241A in the upper row. The character string portion of this message is "That's good," and the specific code is "!-3@userA."

[0126] As explained in the effect table 112 of FIG. 32, the specific code "!-3@userA" is information that identifies the message three messages ago from user A. The message three messages ago from user A is "Hello," which is displayed in bold. In other words, the message three messages ago from user A contains the specific code "!b." Therefore, after operating the "Post" button 243A, "That's good" is displayed in bold as user A's message on the lower viewing screen 241A.

[0127] In the information processing system 1 according to the present embodiment (see FIG. 1), the desired display style for a new post can be specified by identifying other posts. When this function is employed, even a user with little knowledge of the specific code can display their own message in the same display style by simply identifying a message with the display style they want to imitate.

[0128] Eleventh Embodiment In this embodiment, a form of the information processing system 1 (see FIG. 1) described in Embodiment 1 will be described. Therefore, this embodiment also assumes the system configuration and processing operation described in Embodiment 1. A sub-function that changes the presentation of the display mode depending on the positional relationship between a character string portion and a specific code within a character string is added to the display control unit 102 (see FIG. 2) in this embodiment.

[0129] The changes in the effect here include, for example, a change in the size of the effect and a change in the target of the effect. The target of the effect may be, for example, a character string portion located immediately before or after a specific code. An example of this is a display mode in which, for example, if the message is "I'm fine! b", only "fine" is displayed in bold. Another example of the effect may be a display mode in which, for example, if the message is "I'm fine! b", the entire display area (i.e., the card) for "I'm fine" is displayed in bold.

[0130] Furthermore, the display control unit 102 may be provided with a sub-function that, when the specific code is in the first arrangement, displays the display area including the character string portion in a display mode corresponding to the specific code, and, when the specific code is in the second arrangement, displays the character string portion in a display mode corresponding to the specific code. For example, the first arrangement is, as in the input example described above, an arrangement in which the character string portion is "in front" and the specific code is "in back." In this case, the visual effect is applied, for example, to the character string portion. For example, the second arrangement is an arrangement in which the character string portion is "in back" and the specific code is "in front." In this case, the visual effect is applied, for example, to the entire area displaying the character string. The area here is called, for example, a card or a speech bubble.

[0131] Fig. 36 is a flowchart illustrating an example of processing operations including processing corresponding to the sub-functions described in embodiment 11. In Fig. 36, parts corresponding to those in Fig. 6 are assigned reference numerals corresponding to the parts in Fig. 6. The processing operations shown in Fig. 36 are also started when the server 10 (see Fig. 1) accepts a message posting from the user terminal 20 (see Fig. 1). In the example of processing operations shown in Fig. 36, after a positive result is obtained in step 103, the server 10 further determines whether the position of the specific code is at the beginning (step 181).

[0132] If the specific code is located at the beginning, a positive result is obtained in step 181. In this case, the server 10 designates the character string portion as the target of the effect (step 182). On the other hand, if the specific code is located at the end, a negative result is obtained in step 181. In this case, the server 10 designates the entire display area (i.e., the card) in which the character string portion is displayed as the target of the effect (step 183).

[0133] FIG. 37 is a diagram illustrating the effect of the eleventh embodiment. In FIG. 37, the parts corresponding to those in FIG. 16 are denoted by the same reference numerals. In the case of FIG. 37, in order to illustrate the difference in display mode due to the difference in the positional relationship between the character string portion and the specific code within the character string, both the screen transition examples in the left column and the screen transition examples in the right column of FIG. 37 correspond to the user terminal 20A. Note that the screen transitions of the user terminal 20B are the same as those in FIG. 16 except for the upper row.

[0134] In the case of FIG. 37 , "hello !s" has been entered in input field 242A of message application screen 240A1 shown in the left column. That is, the specific code is placed at the end of the character string. On the other hand, "!s hello" has been entered in input field 242A of message application screen 240A1 shown in the right column. That is, the specific code is placed at the beginning of the character string. Therefore, on viewing screen 240A2 in the lower left column, the character string portion "hello" is swung left and right, whereas on viewing screen 240A2 in the lower right column, the entire card including "hello" is swung left and right.

[0135] In the information processing system 1 (see FIG. 1) according to the present embodiment, by changing the positional relationship between the character string portion and the specific code, it is possible to switch between multiple display modes using one specific code. For example, by changing the position of the specific code, it is possible to switch the target to which the display mode is applied and the magnitude of the change.

[0136] Other Embodiments The invention is not limited to the above-described embodiments. For example, it is possible to combine elements of the respective embodiments as appropriate. The combinations here include the deletion of elements of the respective embodiments.

[0137] (1) For example, the processing operations described in the above-described embodiment may be implemented as a function of a message application running on the user terminal 20. That is, if a sent or received message contains a specific code, the message application may display the corresponding text portion of the message in a display format specified by the specific code. Furthermore, the server 10 and the user terminal 20 may cooperate to reflect movement or other effects in the text. The cooperation may be performed by the server 10 or the user terminal 20. For example, the server 10 may be the main controller and gradually control the progress of the effect. For example, the server 10 may transmit effect parameters (e.g., time, order) to the user terminal 20 each time a message is received, and the user terminal 20 may execute the effect according to the received effect parameters. This allows the processing load to be distributed between the server 10 and the user terminal 20. Furthermore, the amount of control data for effect transmission from the server 10 to the user terminal 20 may be reduced.

[0138] (2) For example, the visual effects described in the above embodiment may be viewable only on the user terminal 20 to which the message is addressed. In this case, the character string entered in the input field 242A (see FIG. 7) or the like is displayed as is in the message app of the user who posted the message. That is, the character string including the specific code is displayed as is on the viewing screen 240A2 (see FIG. 7) or the like.

[0139] (3) For example, in the first embodiment, if a posted character string contains multiple specific codes that specify the style of the character string, only the first specific code may be treated as the valid specific code. The same applies to cases where a posted character string contains multiple specific codes that specify the movement of the character string.

[0140] (4) For example, in the above-described embodiment, an example of a description was explained in which multiple specific codes corresponding to individual effects were combined when instructing multiple effects. For example, an example of a description such as "!b!s" was explained. However, the special symbol "!" from the second onwards may be omitted. For example, in the above-described "!b!s", a description such as "!bs" may be permitted.

[0141] (5) For example, the message app may be provided with a function for displaying the character string portion of a message in a display format specified by a specific code, as described in the above embodiment. That is, the server 10 (see FIG. 1) may be specialized for message forwarding services. In this embodiment, the user terminal 20 (see FIG. 1) on which the message app runs is an example of an information processing device. By having the message app execute functions related to the output of movements and other effects independently, the time from message reception to the reflection of the effects on the display is shortened. That is, the real-time performance of the effects is improved. Furthermore, the impact of communication delays is reduced compared to when communication between the server 10 and the user terminal 20 is required to reflect the effects on the display. Meanwhile, the server 10 does not need to generate a message reflecting the effects (i.e., re-rendering) or communicate sequentially with the user terminal 20. As a result, the processing load on the server 10, which handles a large number of communications, is reduced. Furthermore, the number of rounds of communication between the server 10 and the user terminal 20 is reduced, enabling more efficient use of communication bandwidth. In this case, the user terminal 20 on which the message app runs may notify the server 10 of only minimal information (e.g., information about the specific code). This notification is accumulated as a performance log in the user terminal 20, for example.

[0142] (6) For example, the above-described embodiment assumes the exchange of messages in a social networking service or the like, but may also be applied to a service in which emails are exchanged using email addresses. In this case, the message application is an email application, and the server 10 is a so-called email server.

[0143] (7) In the above embodiment, it is assumed that the sender of the message is a user, but the sender of the message may be the server 10 or another message system.

[0144] (8) In the above-described embodiment, when no display time is specified for multiple specific codes (i.e., a negative result in step 123), the effect corresponding to the multiple specific codes is applied sequentially (step 122). In this case, the display time of each effect is determined by the server 10 (i.e., the system side). However, when multiple effect types (e.g., movement 1 and movement 2) are output consecutively, the effect may be switched by the message app alone. For example, the message app may monitor the output time of the effect and switch to the second effect after a certain time has elapsed since the start of the first effect. In this case, communication from the user terminal 20 to the server 10 to inquire about effect switching can be reduced. Furthermore, by completing the effect switching within the message app, it is possible to eliminate non-execution of effect switching or timing discrepancies due to response delays or communication delays in the server 10. This improves the user experience.

[0145] (9) When applying a dramatic effect as a function of a message app, only the portion of the text to which the dramatic effect is applied may be re-rendered instead of re-rendering the entire screen. Employing this mechanism reduces the processing load on the server 10 and the user terminal 20. In particular, employing this mechanism in the user terminal 20 reduces power consumption and extends the time that power can be supplied from the battery.

[0146] (10) In the sixth embodiment described above, the server 10 is provided with a function for checking for invalid specific codes or combinations of conflicting specific codes. However, a similar function may be provided in the user terminal 20 (e.g., a messaging app) to which a message is input. In this case, it is possible to provide feedback on the input of invalid specific codes or conflicting specific codes as errors before the message is sent to the server 10. This reduces input errors by the user. Furthermore, it is possible to eliminate or reduce the error processing performed by the server 10, thereby reducing the processing load on the server 10. Furthermore, it is possible to distribute the processing load related to error processing between the server 10 and the user terminal 20.

[0147] (11) In addition to the function for checking for invalid or conflicting combinations of specific codes, a function for assisting in the input of correct specific codes may be provided. For example, when an invalid or conflicting specific code is entered, a function for correcting the incorrectly entered code or specific code to the correct specific code or for completing the input to correct the character string may be provided. These functions may be provided in either the server 10 or the user terminal 20. By employing these functions, the frequency with which messages containing incorrect specific codes (e.g., codes that cause performance problems) are sent to the server 10 can be reduced. As a result, the server 10 can reduce the number of processes and communications that require the user to resend a message with correctly entered specific codes, for example. Furthermore, the user terminal 20 can prevent a situation in which a message containing an incorrect code or specific code is sent to the server 10. This reduces the number of times the server 10 detects errors in messages (i.e., the error rate).

[0148] (12) When the process of reflecting a visual effect specified by a specific code in a character string is repeated, the user terminal 20 may autonomously re-execute (i.e., reflect) the visual effect. In other words, a mechanism may be adopted in which the user terminal 20 does not inquire of the server 10 about re-executing the visual effect each time the visual effect is re-executed. However, rather than completely eliminating inquiries about re-executing the visual effect, the user terminal 20 may inquire of the server 10 about re-executing the visual effect, for example, once every several times. This mechanism can reduce the number of communications between the server 10 and the user terminal 20. As a result, the processing load on the server 10 is reduced, and the communication load is also reduced. In addition, delays in displaying visual effects due to processing delays, communication delays, etc. are also reduced. This improves the user experience.

[0149] (13) When the user terminal 20 receives a message containing an incorrect specific code (e.g., a code that causes a malfunction in the presentation), the incorrect specific code may be corrected to a recommended specific code or a combinable specific code, and the message may be displayed. This reduces the display of meaningless character strings that do not provide a presentation effect. It also prevents communication with the server 10 regarding inquiries about the incorrect specific code. Furthermore, by simply resolving the presentation effect error on the user terminal 20, it is possible to simplify synchronization control of the display between the sender and receiver via the server 10.

[0150] (14) In the above-described eighth and ninth embodiments, a mechanism is adopted in which candidates for specific codes that can be combined are presented on the assumption that the user has input a character string. However, candidates for messages that include specific codes may be presented to the user based on the content of exchanges on the timeline or the content of the most recent message from the other party.

[0151] (15) In the above-described eighth and ninth embodiments, a mechanism is employed in which, if a specific code exists that can be combined with a character string entered by a user, candidate specific codes are presented. Incidentally, the proposed candidate specific codes are targeted at the most recent character string. However, one or more character strings for which a specific code effect is recommended may be presented to the user after the user has finished entering a character string, or after a specific operation is received while the user is entering a character string. This makes it possible to make the user aware of new effect possibilities. It also improves the user experience.

[0152] (16) In the eighth embodiment described above, a function was described that illustrates the display mode when an input character string is combined with a specific code candidate. This example only applies to character strings that combine specific codes. Therefore, a preview button may be provided in addition to the "Post" button 243A, allowing the user to check the overall effect of the message to be posted. By employing this mechanism, the user can check in advance the impression of the overall effect of the message and the combination of multiple effect combinations.

[0153] (17) In the above-described embodiment, any pre-prepared specific code can be combined with an unlimited number of character strings. However, the specific codes that can be combined may be controlled based on a policy applied to the sender (e.g., user policy, group policy) or the recipient (e.g., user policy, group policy). The policy may be determined based on, for example, the user's age, gender, religion, country or region, the organization (e.g., company, organization, school, class, group, team), or business partner. This allows for different use of special effects using specific codes. Furthermore, the policy to be applied may be switched based on the content of the exchange on the timeline or the most recent message from the other party. For example, if a special effect that evokes special meaning when combined with other special effects (including when used with specific character strings) is present on the timeline, a policy may be applied that restricts posting of the special effect.

[0171] <Twelfth Embodiment> Next, a twelfth embodiment of the present disclosure will be described based on the example screens of Figures 38 to 47. In the twelfth embodiment, a special UI is used to specify the display mode of the character string to be posted, without including a specific code in the character string to be posted. The following UI display is displayed on the display 24 by the processor 21 of the user terminal 20 performing processing based on a program stored in the memory 22.

[0172] 38 shows an example of a viewing screen 300 for viewing messages posted by multiple users including user A and user B. The viewing screen 300 is displayed on the display 24 of the user terminal 20 operated by user A or user B, for example. Data (display data) for displaying the viewing screen 300 may be generated by the server 10 based on data received from the user terminal 20. The server 10 then transmits the display data to the user terminal 20, and the processor 21 of the user terminal 20 processes the display data, thereby displaying the viewing screen 300 on the display 24. In this embodiment, the viewing screen 300 will be described as being displayed on the user terminal 20 operated by user B.

[0173] As shown in FIG. 38 , the viewing screen 300 includes a timeline display area 310, a message creation button 320, a message search field 330, and a menu display area 340. The viewing screen 300 is displayed on the display 24 of the user terminal 20 of each of the message sender and recipient. The timeline display area 310 displays messages posted by multiple users in chronological order. In the example of FIG. 38 , a first message display area 311, a second message display area 312, and a third message display area 313 are displayed, but the number and content of the displayed messages are merely examples and are not limited thereto. The first message display area 311 displays information identifying the user who posted the message, information regarding the time the message was posted, and the message. The first message display area 311 has a rectangular card shape and can be displayed separately from the second message display area 312 and the third message display area 313. The same information and shape apply to the second message display area 312 and the third message display area 313. In this embodiment, the posts are displayed in order from the most recent to the most recent posting time from top to bottom.

[0174] Message search conditions can be input in the message search field 330, and messages that match the search conditions input in the message search field 330 can be extracted from posted messages. Menu display area 340 has menus such as "Home," "Search," "Community," "Notification," and "Message."

[0175] When the message creation button 320 is pressed (an example of a first operation), an input screen 400 for creating a message to post is displayed. An example of the input screen 400 will be described with reference to FIG.

[0176] As shown in FIG. 39, an input screen 400 displays a message creation area 410, a specific mode display area 420, a keyboard display area 430, a cancel button 440, and a post button 445.

[0177] The message creation area 410 includes a sender icon 411, a destination selection area 412, and an input area 413. The sender icon 411 is information that identifies the sender of the message to be posted. For example, if user B presses the message creation button 320, user B becomes the sender.

[0178] The destination selection area 412 is an input field for specifying the destination to which the message is to be sent, and it is possible to specify a group or an individual user. Information about the message to be posted (an example of a first character string) is input into the input area 413. The message can be input using, for example, a keyboard displayed in the keyboard display area 430.

[0179] The specific mode display area 420 displays a specific mode icon 421 for accepting an operation to set a special display mode for the message to be input in the input area 413. When the specific mode icon 421 is selected (an example of a second operation), a mode selection area 450 shown in FIG.

[0180] As shown in FIG. 40, the mode selection area 450 includes a first designation area 451 , a second designation area 452 , a third designation area 453 , and a close button 454 .

[0181] The first designation area 451 is an area for setting a movement for a message input in the input area 413. For example, in the first designation area 451, it may be possible to set one movement to be applied from among a plurality of types of movements (M1 to M3). In this embodiment, it is assumed that a maximum of one movement can be set in the first designation area 451, but it may also be possible to set two or more movements. The movements that can be set for a message are not limited to the examples shown in this embodiment.

[0182] The second designation area 452 is an area for setting the style of the message to be input in the input area 413. For example, in the second designation area 452, it may be possible to set one style to be applied from among a plurality of styles (S1, S2). In this embodiment, a maximum of one style can be set in the second designation area 452, but two or more styles may also be set. The styles that can be set for a message are not limited to the examples shown in this embodiment.

[0183] The third designation area 453 is an area for setting an effect to be applied to the display area on the viewing screen 300 where the message input in the input area 413 is displayed. That is, the effect set in the third designation area 453 is applied, for example, to the unit of the message display area on the viewing screen 300. For example, the third designation area 453 may be configured to set one effect to be applied from among a plurality of types of effects (E1, E2). In this embodiment, a maximum of one effect can be set in the third designation area 453, but two or more effects may also be set. The effects that can be set for the message display area are not limited to the example shown in this embodiment.

[0184] As shown in Fig. 41 , for example, when a movement, style, or effect to be applied is selected in the first to third designation areas 451 to 453 of the mode selection area 450, the selected mode is displayed in an identifiable manner. The example of Fig. 41 indicates that M2 is selected as the movement, S1 as the style, and E1 as the effect. Note that the first to third designation areas 451 to 453 may include one or more movements, styles, and effects that do not specify a mode to be applied. The respective modes of the movement, style, and effect selected in the mode selection area 450 are displayed in the mode display area 414 of the message creation area 410.

[0185] When the close button 454 of the mode selection area 450 is selected, the display of the mode selection area 450 can be hidden. Note that even when the mode selection area 450 is closed, the display of the mode display area 414 is maintained, so that the user can recognize the selected mode.

[0186] When the post button 445 on the input screen 400 is selected (an example of a third operation), a process is executed in which the character string (an example of a first character string) entered in the input area 413 is posted to the posting destination specified in the destination selection area 412 based on the mode specified in the mode display area 414. Specifically, in response to the selection of the post button 445, the display 24 of the user terminal 20 transmits posting data including information on the destination, the message, and the set mode to the server 10. The server 10 generates a viewing screen 300 based on the posting data and displays it on the display 24 of the user terminal 20.

[0187] 42 shows a fourth message display area 314 that displays a message posted on the viewing screen 300 based on the mode specified in FIG. 41. As shown in the fourth message display area 314, the fourth message display area 314 includes a message 314A and a performance image 314B. The message 314A is displayed with a motion "E1" and a style "S1" applied. For example, the motion "E1" may be a manner in which a character string is moved left and right, and the style "S1" may be a manner in which the character size is increased to a first size.

[0188] Furthermore, a performance image 314B is displayed superimposed on the fourth message display area 314. The performance image 314B is not displayed in the third message display area 313 or the second message display area 312, but is selectively displayed in the fourth message display area 314 in which the performance image 314B is specified. The performance image 314B may be displayed superimposed on at least a portion of the fourth message display area 314 other than the area in which the message 314A is displayed. For example, the performance image 314B may be displayed superimposed on an area in the fourth message display area 314 that does not overlap with the message 314A, without being superimposed on the area in the fourth message display area 314 in which the message 314A is displayed. Also, for example, the performance image 314B may be displayed superimposed on the entire fourth message display area 314. The area in which the performance image 314B is displayed may be predetermined for each type of performance image 314B (i.e., each performance mode).

[0189] 43 and 44 show other examples of the display mode applied to fourth message display area 314. As shown in Fig. 43, when the application of style "S2" and effect "E1" to the message to be posted is selected and then post button 445 is selected, as shown in Fig. 44, a message 314C to which style "S2" has been applied and a performance image 314D corresponding to effect "E1" are displayed in fourth message display area 314. In this way, it is possible to easily set the display mode to be applied for each message to be posted and each message display area.

[0190] In the examples described so far, after entering a message to be posted in the input area 413 on the input screen 400, a mode is selected in the mode selection area 450. However, this is not limited to this. For example, as shown in FIG. 45 , it is also possible to select a specific mode icon 421 without entering any text in the input area 413, and then set a mode to be applied to the text to be entered in the input area 413 in the mode selection area 450 of FIG. 46 . Even in this case, as shown in FIG. 47 , the display mode to be applied to the text entered in the input area 413 is displayed in the mode display area 414, allowing the user to easily recognize which display mode is being set. It may be possible to change the text entered in the input area 413 and the mode set in the mode display area 414 before pressing the post button 445.

[0191] According to the twelfth embodiment described above, it is possible for the poster to change the display mode of posted information viewed by recipients through simple specification, without embedding a specific code in a character string. Furthermore, it is possible to provide a UI that allows the poster to easily recognize the effects to be applied to a message before posting the message. Note that the above-described embodiments can be combined as appropriate.
