  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an overall configuration of a chat system according to an embodiment of the present invention. As shown in the figure, the chat system includes a server 12 and clients 16A and 16B. The server 12 and the clients 16A and 16B are all connected to a data communication network 14 such as the Internet and can communicate data with each other. Hereinafter, when it is not particularly necessary to distinguish the clients 16A and 16B, they are simply referred to as the client 16.

  The server 12 is realized by a well-known server computer mainly composed of a processor, various storage devices, and a data communication device, and manages and relays chats performed by the clients 16A and 16B. On the other hand, the client 16 is realized by various computer systems such as a well-known personal computer or a well-known computer game system mainly composed of input means such as a monitor and a keyboard, a processor, various storage devices, and a data communication device. Yes, each user has a chat (conversation by sending and receiving message character strings).

  FIG. 2 shows an example of a chat screen displayed on the monitor of the client 16A. A similar chat screen is also displayed on the monitor of the client 16B. As shown in the figure, on this chat screen, the principal information display area 20A corresponding to the user of the client 16A (hereinafter referred to as “user A”) and the chat partner, that is, the user of the client 16B (hereinafter referred to as “user A”). Then, a partner information display area 20B corresponding to “User B”), a message character string input field 26 for inputting a message character string, and an emotion type input field 18 are provided. An avatar image 24A representing the user A is displayed in the personal information display area 20A. A balloon image 22A is displayed below the personal information display area 20A, and message character strings input by the user A are sequentially displayed in the balloon image 22A. Similarly, an avatar image 24B representing the user B is displayed in the partner information display area 20B. A balloon image 22B is displayed below the partner information display area 20B, and message character strings input by the user B are sequentially displayed in the balloon image 22B. The message character string input field 26 is a character string editing area used for the user A to input a message character string (a character string that is a message to the other party) using character input means such as a keyboard, and is displayed in the same field. A message character string can be completed by sequentially inputting characters at the cursor position. Then, by performing an input completion operation such as a return key, the message character string displayed in the same column can be transmitted to the user B who is a chat partner. The emotion type input field 18 displays characters “Kiragaku”, “Angry”, “Sorrow”, and an avatar representing the user A by selecting one by a predetermined emotion type switching operation. The emotion type of the image 24A can be set and input. Thereby, the facial expression of the avatar image 24A can be changed.

  As described above, the client 16B used by the chat partner also displays a chat screen similar to that shown in the figure, in which the same image as the avatar image 24A is displayed in the partner information display area. ing. The same image as the avatar image 24B is displayed in the personal information display area. For this reason, when the user A sets and inputs the emotion type of the avatar image 24A in the emotion type input field 18 and changes the expression of the avatar image 24A, the user A is displayed in the partner information display area on the chat screen of the client 16B. Avatar images also show similar facial expression changes. In this way, it is possible to convey emotions to the chat partner, that is, the user B using not only characters but also an avatar image.

  The client 16 can display a chat log on a monitor by performing a specific operation. FIG. 3 shows an example of this chat log. As shown in the figure, the chat log includes a character (“A” or “B” in this case) for identifying users A and B who are chat parties, a message character string which is a statement of the chat party, The images corresponding to the emotion type and the emotion level corresponding to the chat party who input the message character string at the time when the message character string is displayed are displayed in time series in association with each other. In the chat screen already explained, only the latest utterance is displayed in the balloon images 22A and 22B, and the past utterance is not displayed. It can be done.

  The avatar images 24A and 24B are stored in advance in the storage unit of the client 16, and are selectively read out from the storage unit and displayed on the monitor. 4 to 6 show a group of avatar images stored in the storage unit of the client 16. FIG. 4 shows an avatar image group corresponding to the emotion type “Kiraku”. Specifically, FIG. 9A shows a group of avatar images corresponding to the emotion type “joy” and the emotion level “1”. Similarly, FIG. 5B shows a group of avatar images corresponding to the emotion type “Pleasure” and the emotion level “2”, and FIG. 4C shows the emotion type “Pleasure” and the emotion level. An avatar image group corresponding to “3” is shown, and in FIG. 9D, an avatar image group corresponding to the emotion type “joy” and the emotion level “4” is shown. As you can see in the figure, even if the emotion type is the same, as the emotion level increases, the intensity of the emotion increases, and the expression of the avatar image changes accordingly. It has become.

  The client 16 stores a plurality of avatar images in association with the same emotion type and the same emotion level. These are avatar images indicating different characters. That is, in this chat system, for example, a plurality of characters depicting “male in their 20s”, “female in their teens”, “female in their 40s”, etc. are prepared, and each emotion type and each character are associated with each character. An image (avatar image) corresponding to the emotion level is created in advance. In this embodiment, the user designates a character to be used as his / her avatar image in advance, and in the chat screen shown in FIG. 2, the character image thus designated by the user is used as the user's avatar image. It is displayed.

  As in the case of the emotion type “Kiraku”, FIG. 5 shows a group of avatar images corresponding to the emotion type “anger”. Specifically, FIG. 5A shows an avatar image group corresponding to the emotion type “anger” and the emotion level “1”. Similarly, FIG. 6B shows an avatar image group corresponding to the emotion type “anger” and the emotion level “2”, and FIG. 10C shows the emotion type “anger” and the emotion level. An avatar image group corresponding to “3” is shown, and FIG. 9D shows an avatar image group corresponding to the emotion type “anger” and the emotion level “4”. FIG. 6 shows an avatar image group corresponding to the emotion type “sorrow”. Specifically, FIG. 9A shows an avatar image group corresponding to the emotion type “sorrow” and the emotion level “1”. Similarly, FIG. 7B shows an avatar image group corresponding to the emotion type “sorrow” and the emotion level “2”, and FIG. An avatar image group corresponding to “3” is shown, and FIG. 9D shows an avatar image group corresponding to the emotion type “sorrow” and the emotion level “4”.

  Here, the expression change of the avatar image will be described in more detail. FIG. 7 is a diagram for explaining facial expression changes of avatar images corresponding to user A and user B. FIG. In the first column of the figure, a character (“A” or “B”) that identifies a user who transmitted a message character string or performed an emotion type switching operation is described. In the second column, the content of the transmitted message character string or the fact that the emotion type switching operation has been performed is described. The expression of the avatar image corresponding to the user A is written in the third column, and the expression of the avatar image corresponding to the user B is written in the fourth column. In the third and fourth columns, for example, “laugh” represents the emotion type “Kuraku”, “anger” represents the emotion type “anger”, and a numerical value such as “1” represents the emotion level. Yes. In the figure, for example, from due to user A, "Hello.", Because due to user B input interval of up to "Hello!" Is short, the emotion level is raised, the facial expression of the avatar image corresponding to the user B, "laughs 1" Has changed to "LOL 2". Further, when the user A performs an emotion type switching operation after inputting “By the way, there is an incident at XX ...”, the expression of the avatar image corresponding to the user A is changed to “anger 1”. That is, in this embodiment, when the emotion type switching operation is performed, the emotion level is reset to 1 accordingly.

  Hereinafter, the configuration and operation of this system will be described in more detail.

  FIG. 8 is a diagram illustrating a functional configuration of the server 12. As shown in the figure, the server 12 functionally includes a communication unit 30, an emotion data management unit 32, and an emotion data storage unit. These functional blocks are realized by executing predetermined programs in the server 12. The communication unit 30 includes, for example, a known data communication card, and performs data communication with the client 16 via the data communication network 14, and particularly receives a message character string transmitted from the client 16A. And transfer it to the client 16B. Also, the message character string transmitted from the client 16B is received and transferred to the client 16A. At this time, the time when the message character string is received from each client 16 is notified to the emotion data management unit 32 as the input timing of the message character string in the client 16.

  Further, when the communication unit 30 receives the emotion type data from the client 16A or 16B, it passes it to the emotion data management unit 32. In addition, it receives an emotion data update request representing emotion data update content from the emotion data management unit 32, and transmits it to the client 16A and the client 16B. The emotion data is data including at least one of emotion type data and emotion level.

  The emotion data management unit 32 manages and distributes emotion data stored in the emotion data storage unit 34. That is, the emotion data storage unit 34 includes a storage means such as a hard disk storage device or a RAM, and stores emotion data. FIG. 9 shows an example of emotion data stored in the emotion data storage unit 34. As shown in the figure, emotion data includes information for identifying each user who is chatting, the time when the user previously entered a message string, the emotion type currently set (specified), and the current Corresponding to the emotional level. Here, it is noted that the current emotion type of user A is “Karak”, the emotion level is “2”, and that the previous message string was input at 18:30:25. Yes. In addition, it is described that the current emotion type of the user B is “anger”, the emotion level is “1”, and the immediately preceding message character string was input at 18:30:14. .

  When emotion data management unit 32 first receives emotion type data from client 16, emotion data management unit 32 changes the emotion type stored in emotion data storage unit 34 in association with the user of client 16 to that indicated by the emotion type data. To do. At this time, the emotion level stored in the emotion data storage unit 34 in association with the user is initialized to 1.

  When the message character string is received from the client 16 and the input timing of the message character string is notified from the communication unit 30, the emotion data is stored in association with the time and the chat partner of the user who transmitted the message character string. The difference from the previous input time stored in the unit 34 is calculated. Then, the difference is divided by the character amount of the message character string received from the client 16, and the time difference per unit character amount is calculated. If the time difference per unit character amount is less than the first predetermined value, the emotion level stored in the emotion data storage unit 34 is increased by 1 in association with the user who transmitted the message character string. If the emotion level is already the maximum value, the same level increasing process is not performed. On the other hand, if the time difference per unit character amount is equal to or larger than a second predetermined value different from the first predetermined value, it is stored in the emotion data storage unit 34 in association with the user who transmitted the message character string. Decrease the emotion level by 1. If the emotion level is already the lowest value, the level lowering process is not performed. In this way, when a message character string corresponding to a message character string input from a chat partner is promptly input, the user's emotion level can be increased. When the response is dull, the emotion level of the user can be lowered.

  Thereafter, the time notified by the communication unit is stored in the emotion data storage unit 34 in association with the user who is the sender of the message character string, thereby updating the previous input time. Then, the update contents of the emotion data stored in the emotion data storage unit 34, that is, the emotion data update request representing at least one of the emotion type data and the emotion level is transmitted to both the client 16A and the client 16B.

  When the message character string is received from the client 16 and the input timing of the message character string is notified from the communication unit 30, the time is associated with the user who transmitted the message character string in the emotion data storage unit 34. You may calculate the difference with the last input time memorize | stored. Then, the difference is divided by the character amount of the message character string received from the client 16, and the time difference per unit character amount is calculated. If this time difference is less than the first predetermined value, the emotion level stored in the emotion data storage unit 34 is increased by 1 in association with the user who transmitted the message character string, and the first predetermined value If it is equal to or greater than a different second predetermined value, the emotion level stored in the emotion data storage unit 34 may be lowered by 1 in association with the user who transmitted the message character string. In this way, for users who send message strings one after another, the emotion level is raised, and conversely, when the interval for sending message strings is long, or when the message string input work itself is slow, The user's emotion level can be lowered.

  FIG. 10 is a diagram illustrating a functional configuration of the client 16. As shown in the figure, the client 16 functionally includes a communication unit 40, a message input unit 42, a display unit 44, an avatar image storage unit 46, an emotion data storage unit 50, and an emotion type input unit 48. ing. These functions are realized by executing a predetermined program in the client 16.

  First, the communication unit 40 receives a message character string received from the server 12 and supplies it to the display unit 44. Further, when emotion data is received from the server 12, the content is reflected in the content stored in the emotion data storage unit 50. When a message character string is input by the message input unit 42, the message character string is transmitted to the server 12. In addition, emotion type data is input to the communication unit 40 from the emotion type input unit 48, and when this emotion type data is received, it is transmitted to the server 12.

  The message input unit 42 includes character input means such as a keyboard in particular, and causes a message character string to be input to the message character string input field 26 on the chat screen. The input message character string is combined with the balloon image 22 on the chat screen on the display unit 44 and displayed on the monitor.

  The avatar image storage unit 46 includes, for example, a hard disk storage device, and stores various avatar images described in FIGS. 4 to 6. The emotion data storage unit 50 stores an emotion type and an emotion level in association with each user who is a chat party. Of these, the emotion type corresponding to the user of the client 16 can be set and input by the emotion type input unit 48. In this case, by selecting a character indicating each emotion type in the emotion type input field 18, the emotion type corresponding to the character can be stored in the emotion data storage unit 50 in association with the user of the client 16. It is like that. Moreover, when the communication part 40 receives the emotion data update request from the server 12, the emotion data storage part 50 is updated according to the content.

  The display unit 44 reads the emotion type and emotion level of each user from the emotion data storage unit 50 and reads the corresponding avatar image from the avatar image storage unit 46. At this time, the display unit 44 acquires the character designation of each user in advance, and reads the avatar image corresponding to the designated character. The read avatar image is displayed on the principal information display area 20A and the partner information display area 20B by the display unit 44, respectively.

  Here, the processing of the server 12 will be further described. FIG. 11 is a flowchart showing emotion data management processing by the server 12. As shown in the figure, the server 12 monitors whether or not a message character string is received from any one of the clients 16 (S101). The current time is acquired (S102). Further, the previous input time corresponding to the chat partner user is read from the emotion data storage unit 34, and the elapsed time t1 from there to the current time is calculated (S103). If the elapsed time t1 is less than the first predetermined value TA, the emotion level stored in the emotion data storage unit 34 is increased by 1 in association with the user who is the sender of the message character string. Update (S105). At this time, if the emotion level has already reached the maximum value, the process in S105 is not performed. On the other hand, if the elapsed time t1 is greater than or equal to the first predetermined value TA, the process of S105 is skipped. Further, it is determined whether or not the elapsed time t1 is greater than a second predetermined value TB (TB> TA) (S106). If so, the emotion level stored in the emotion data storage unit 34 is updated so as to be lowered by 1 in association with the user who is the sender of the message character string (S107). At this time, if the emotion level has already reached the minimum value, the process in S107 is not performed. On the other hand, if the elapsed time t1 is equal to or shorter than the second predetermined value TB, the process of S107 is skipped.

  Thereafter, the emotion level updated as described above is transmitted to each client 16 as an emotion data update request (S108). Further, the current time acquired in S102 is stored in the emotion data storage unit 34 in association with the user who is the sender of the message character string. Thus, the previous input time is updated.

  According to the chat system described above, the expression of the avatar image automatically changes according to the input timing of the message character string. Therefore, no special input for changing the expression of the avatar image is required, and user convenience Can greatly improve performance.

  The present invention is not limited to the above embodiment.

  For example, in the above description, the avatar image is changed according to the input timing of the message character string. However, the client 16 outputs a sound, and this sound is changed according to the input timing of the message character string. May be. The sound in this case is music or a voice that reads out a message character string, for example. Even in this way, the emotion of the chat partner can be determined from the change in sound.

  In the above description, the reception timing in the server 12 is treated as the input timing of the message character string in the client 16, but when the message character string is input in the client 16, the current time is acquired and If the server 12 is made to transmit, the timing closer to the timing when the message character string is input can be handled as the input timing of the message character string in the client 16.

  Also, here, the emotion level is raised or lowered according to the elapsed time from the input timing of the immediately preceding message character string to the input timing of the current message character string, but the same elapsed time or it is divided by the amount of characters. The emotion level may be associated with the range of values. In this way, the emotion level can be changed rapidly. Further, other statistics such as an elapsed time or an average of values obtained by dividing the elapsed time by the amount of characters may be calculated, and the emotion level may be determined accordingly.

  Furthermore, although the server 12 manages emotion data here, it may be performed by each client 16. FIG. 12 is a diagram showing a functional configuration of the client 16 according to this modification. As shown in the figure, this example is characterized in that an emotion data management unit 52 is provided in the client 16. Other configurations are the same as those in FIG. 10, and the same reference numerals are given here, and detailed description thereof is omitted.

  The emotion data management unit 52 receives a message character string from the message input unit 42 and further receives a message character string received from the other client 16 from the communication unit 40. When a message character string is input from the message input unit 42, the current time is acquired by a time measuring unit (not shown), and the previous input time corresponding to the chat partner stored in the emotion data storage unit 50 is read. The elapsed time from there to the current time is read out. Then, similarly to the case of FIG. 11, the emotion level is changed according to this elapsed time. Further, when a message character string is input from the communication unit 40, the current time is acquired by a timing unit (not shown), and the previous input time corresponding to the user of the client 16 stored in the emotion data storage unit 50 is obtained. Read and read the elapsed time from there to the current time. Then, similarly to the case of FIG. 11, the emotion level is changed according to this elapsed time. In this case, the timing at which the client 16 receives the message character string is handled as the input timing of the message character string.
