ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a method of improving a expression of a chat in the form of text, which is one of communication technologies using a network, such as the Internet.
FIG. 1
shows a general configuration of a chat system. The chat system includes a server computer
100
and client computers
110
-
1
n
0
, n in number. A chat server unit
101
is operated on the server computer and chat clients
111
-
1
n
1
are each operated on the corresponding client computer
110
-

.
The chat client
111
includes a message producing unit
112
and a message displaying unit
113
. The server computer
100
includes the chat server unit
101
. The chat client

includes a message producing unit

and a message displaying unit

.
Sending and receiving operations of a message are performed in the chat system as follows.
The chat client
111
makes up a message at the message producing unit
112
, and sends the message to the chat server unit
101
and the message displaying unit
113
. The chat server unit
101
collects messages from the chat clients connected the chat server unit, and distributes the collected messages to the chat client
1
n
1
. In this event, the messages are distributed only to the chat clients connected to chat rooms managed by the chat client. The message displaying unit
113
in the chat client
111
and the message displaying unit
1
n
3
in the chat client
1
n
1
display the sent messages on the respective screens.
FIG. 2
shows an example of a conventional chat screen of each of the chat clients. As shown in
FIG. 2
, in the typical system, messages supplied to the chat clients are displayed on a screen of white background color successively from the upper part to the lower part in a chat or conversation order. Messages displayed on the chat screen include only nicknames (such as “reiji” and “Urashiman” shown in
FIG. 2
) and their statements.
FIG. 3
shows an operation flow of the message producing unit in the chat client. In step A
1
in
FIG. 3
, statements are supplied to the message producing unit. Next, the message producing unit of the chat client generates a message on the basis of the statement in step A
2
and appends, to the statement, a nickname which corresponds to people who state in step A
3
. Finally, the message to which the nickname is appended is sent in step A
4
.
FIG. 4
shows a processing flow of the message displaying unit in the chat client. In step B
1
in
FIG. 4
, the message displaying unit in the chat client receives a message from the server and divides the message into a statement and a nickname in step B
2
. In step B
3
, the message displaying unit calculates each display position of the statement and the nickname on a screen. Next, in step B
4
, the message displaying unit determines whether or not the calculated value of the position exceeds a size of the screen. If the value exceeds the size of the screen, that is, the screen becomes full of messages, processing of the message displaying unit proceeds to step B
5
. Otherwise, processing is followed by step B
7
. In step B
5
, the message displaying unit scrolls the screen and secures an area on which the new message are displayed. Next, in step B
6
, a new display position of the message is calculated again, and in step B
7
, the nickname and the statement are displayed. If there is no need to scroll, they are displayed at the position obtained in step B
4
.
FIG. 5
shows a relationship between a message and contents displayed on a screen. When the chat client receives the message
210
shown in
FIG. 5
, the message is divided into a nickname
211
and a statement
212
which are displayed on a client screen
410
as shown in FIG.
5
.
The conventional chat system has following problems.
A first problem is to lack ability of expression about a chat screen. This is because the background color of the screen is monotonous and, in addition, messages are simply displayed from the left most of the screen, and the messages are constantly displayed from the upper part on the screen to the lower part.
A second problem is that a sender of a message can not convey his/her feelings. This is because representation on display of the statement is standardized, as shown in FIG.
5
.
A third problem is that a sender of a message can not easily be distinguished from each other. This is because each sender can not be intuitively recognized who sends the previous statement. Since identification of a sender is displayed on the left most of a screen by using his/her nickname, the nickname must be read again to know a sender of the previous statements.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a text base chat system which improves ability in expression related to feelings and intention of a sender so that smooth communication may be performed via a network (the Internet).
According to the invention, there is provided a chat screen displaying system including a server and a plurality of clients connected to the server via a network, each of the clients including a message producing unit which transfers a message from a sender to the server, and a message displaying unit which displays the transferred message from the server, wherein the message producing unit appends shape information representing a balloon form specified by the sender and sender information representing the sender to statement data representing the statement from the sender to produce the message and to transfer the message to the server and the message displaying unit, and wherein the message displaying unit divides the received message into the statement data and shape information and displays at least the statement data on a screen with the statement surrounded by the balloon form specified by the shape information.
It is also desirable that the message producing unit further appends a user ID of the sender to the message and transfers the message, and wherein the message displaying unit retrieves a color table which resides in the message displaying unit based on the user ID, and displays the statement data using the retrieved color as a background color in the balloon form related to the statement data.
Further, it is desirable that the message displaying unit sets a new color as a background color which corresponds to the user ID and stores the new color and the corresponding user ID in the color table, when a color which corresponds to the user ID is not present in the color table.
Further, it is desirable that the message displaying unit displays the balloon form at random on the screen.
According to the above invention, when a statement is displayed on a screen, it allows to display a balloon-formed frame which surrounds the statement and the shape of the frame can be easily selected by a user. Further, it allows to display an image on a background of the screen used to display chat message, and display a statement in random position in lateral direction. Further, in displaying the statement, it allows to display the statement with color which corresponds to its sender.
