Description

BACKGROUND OF THE INVENTION

The present invention relates to a chat system for realizing conversation using characters, more specifically relates to a chat system having characteristics in display of attribute information of channels and a procedure for changing the channels, a chat server, a client and a computer memory product.

There exists a chat system as means for exchanging information between clients. An arrangement example of this chat system will be described based on FIG. 1 . The chat system is arranged so that a chat server 1 as a host computer is connected with a plurality of clients 2 through 5 via a network 6 of a public line, and the chat server 1 transmits a message received from one of the clients 2 through 5 immediately to another clients so that conversation using characters between users who operate their clients is realized.

The aforementioned chat system displays the message, namely, a stated content and a name of the stating person correspondingly on the clients 2 through 5 . Therefore, even if a plurality of users make statements simultaneously, mismatch of the stated contents and the people who made the statements is not generated on receiving sides, so it is effective for smooth progress in exchanging opinions. Moreover, since the conversation contents displayed on the clients 2 through 5 can remain as text data directly, a record can be easily created from the text data.

One embodiment of the chat system is such that one chat server is used and a plurality of channels are used. The channel represents an imaginary discourse room, and statements of another users in the discourse room can be received. A state such that the statements can be transmitted to other users is called “participations”. Namely, users can join in the conversation in the channel by permitting the users to participate in the channel.

In the chat server, a statement received in a channel is transmitted only to other users participating in the channel, and thus the statement cannot be received by users participating in other channels, so independence between channels is secured.

In addition, this chat server is arranged so as to generate a new channel according to a user's requirement and to permit users, who access to the new channel after the new channel is generated, to participate in the new channel.

Attribute information such as a number of clients participating in each channel, a set topic and channel mode is given to the users who accessed to the chat server. The channel mode includes a secret mode which conceals existence of the channel from the users who don't participate in the channel, an invite only mode which permits only users who invited by the users participating in the channel to participate in the channel, and a channel key mode which permits only users who input a set password to participate in the channel.

Users select one channel based on the aforementioned information to participate in the channel. In other words, the chat system is constructed assuming that the users concentrate on the conversation in one channel.

With the spread of an Internet and intranet, opportunity to exchange information via clients has been increased, and accordingly it is required to further improve convenience of the aforementioned chat system.

“CLIENT OF A CHAT SYSTEM, CHAT SYSTEM, DISPLAY METHOD AND COMPUTER MEMORY PRODUCT OF A CHAT SYSTEM” (U.S. Ser. No. 08/805,779: hereinafter referred to as senior application), which has been suggested by the applicant of the present invention, is the invention which was devised in order to satisfy such a requirement, and it is an object of the senior application to provide a chat system which can be used for works in an office, for example.

The chat system of the senior application is arranged so that a user who does not participate in a channel can receive statements of users participating in the channel. This state is called “registration”. A difference between “registration” and aforementioned “participation” is that statements of users who are permitted to “register” are not received in an objective channel. Namely, a user who is permitted to “register” at a channel can only view conversation in the channel.

More specifically, the chat system of the senior application displays conversation in a channel to which a user who operates a client pays attention, more specifically in the channel in which the user participates, and conversation in a channel at which the user registers on different areas of a display screen. Moreover, this chat system provides statement means in the channel in which the user participates. Furthermore, when the statement displayed on the display screen in the channel at which the user registers is designated by using a pointing device or the like, this chat system changes the channel in which statement is possible and permits the user to participate in the channel where the statement is made.

Therefore, a user who uses the chat system of the senior application views conversation contents in the registered channel sideways and at the same time can enjoy conversation in the participation channel. Further, in the case where the user finds statements relating to an interesting topic in the registered channel, the user designates the statements using the pointing device so as to change easily the channel in which statement is possible into the channel in which the person who is making the statement participates, and thus the user can join in the conversation.

In addition, the aforementioned chat system is arranged so that every time attribute information of each channel at which the user registers, namely, information such as a number of clients registering in the channel, a set topic and a channel mode is changed, the information is transmitted from the chat server to the client which is operated by the user.

Further, the transmitted information is stored on the client side, and the information can be displayed on a screen according to an operation by the user at any time. The displayed information is often utilized for selecting a channel at the time of changing the channel in which statement is possible.

The attribute information of the each channel, namely, information such as a number of clients registering in the channel, a set topic and a channel mode is changed as the topic changes and also as the time proceeds, but in the chat system of the senior application, predetermined operations should be performed every time the information is displayed, so an improvement in convenience of usage has been desired.

In addition, when characters are used for displaying the attribute information in the each channel, for example, topics, it is necessary to read characters which are displayed for making a distinction between topics, so conversation is interrupted during a period required for the reading.

BRIEF SUMMARY OF THE INVENTION

It is one object of the present invention to provide a chat system, chat server, client and computer memory product with which attribute information, a number of times of statements or amount of statements in a channel at which an user operating a client registers can be displayed on the client without an operation by the user.

It is another object of the present invention to provide a chat system, chat server, client and computer memory product with which attribute information, a number of times of statements or amount of statements in a channel can be displayed as images.

It is still another object of the present invention to provide a client of a chat system, chat system and computer memory product with which when displayed attribute information, number of times of statements or amount of statements is designated by using a pointing device or the like, a channel relating to the designation is changed into a channel in which statements are possible.

In the present invention from the first aspect, a name of channel which is permitted to be registered and its attribute information are displayed on each client. Therefore, since the attribute information of the channel permitted to be registered which is changed as the time proceeds is displayed, a user can know a change in the attribute information of the channel permitted to be registered without performing a special operation. Here, examples of the attribute information are a topic of the channel permitted to be registered, a channel mode of the channel permitted to be registered or a number of clients of the channel permitted to be registered, and the user can know their changes easily.

In the present invention from the second aspect, a name of channel which is permitted to be registered and a number of times or amount of statements in the channel are displayed on each client. Therefore, a user can know a change in information representing animation of conversation in the channel permitted to be registered. Moreover, a discrimination can be made between the channel where the conversation is made actively and the channel where the conversation is not active, so a channel can be selected based on the animation of conversation.

In the present invention from the third aspect, the name of the channel permitted to be registered and its attribute information in the first aspect, or the name of the channel permitted to be registered and the number of times or the amount of statements in the channel in the second aspect are displayed as images. Therefore, users can easily view the attribute information or information about the number of times or amount of statements, so a difference in the attribute information and animation of conversation between the channels can be discriminated easily.

In a chat system of the present invention from the fourth aspect, in the case where designation of the displayed attribute information, number of times of statements or amount of statements in the first or second aspect is received, the channel where statements are possible is changed into the channel relating to the designation. Therefore, the users can easily understand the operation for changing channels, and thus the users feel secure.

The above and further objects and features of the invention will more fully be apparent from the following detailed description with accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

The following will describe the present invention on reference to the drawings showing embodiments.

FIG. 1 is a block diagram showing an example of an arrangement of a chat system according to the present invention. A chat server 1 as a host computer is connected with a plurality of clients of the present invention (for example, personal computers) 2 through 5 via a network 6 of a public line. When receiving a message from one of the clients 2 through 5 , the chat server 1 transmits the message to other clients immediately. This arrangement realizes conversation using characters between users who operate their clients.

Since the chat system displays stated contents and corresponding names of people who made the statements on the clients 2 through 5 , even if a plurality of users make statements simultaneously, mismatch between the stated contents and the people who made the statement does not occur on a receiving side.

FIG. 2 is a block diagram showing an example of an arrangement of the client of the chat system according to the present invention. In FIG. 2 , the client 2 is connected with a memory 7 composed of a hard disk device or the like, and the memory 7 stores a directory table 7 a in which names of plural channels are tabulated. In the directory table 7 a , names of channels are described with a format of “#” (or “&”) +“a name of a channel”. “#” and “&” are symbols which represent channels opened to all the servers connected with IRC networks and channels opened only to specified servers based on the IRC (Internet Relay Chat) standard.

FIG. 3 is a flow chart showing a series of processing procedure in the chat system according to the present invention. When actuation of an application program of the present invention is received, connection with a chat server and participation and registration in a channel are made by an access process, mentioned later (S 1 ). Then, attribute information, a number of times of statements or amount of statements in a channel at which a user operating a client registers is transmitted from the chat server to the client by a display process, mentioned later, so as to be displayed (S 2 ). Moreover, publicly known conversation process for controlling transmission and receiving of statements is performed (S 3 ).

Further, control is made by an event process, mentioned later, according to event given from input means provided to the client or the chat server (S 4 ). A judgment is made from the given event as to whether or not the processing procedure is terminated (S 5 ). When the processing procedure is not terminated, the procedure returns to S 2 and the processes thereafter are repeated. When the judgment is made that the procedure is terminated at S 5 , a series of the processes is terminated.

The chat system is provided with publicly known means for changing a participation channel into another channel in a state that the user participates in a certain channel. Moreover, in the process for changing the participation channel using that means, a form of access to the channel participated before the process can be changed from “participation” into “registration”. Namely, when the user participates successively in a plurality of channels using that means, the user can register at the plural channels. In this case, the channel in which the user participated at last becomes a channel in which statements are possible.

FIG. 4 is a flow chart showing the access procedure (S 1 in FIG. 3 ) in the client of the chat system according to the present invention. The client accesses to the chat server by means of publicly known access means (S 6 ) so as to participate in a channel which is described in a top record of the directory table 7 a (S 7 ). Then, a judgment is made as to whether or not one or more channels in which the client does not participate remain in the directory table 7 a (S 8 ). When the channel remains, the client participates in a next channel via the aforementioned channel changing means, and the form of access to the channel in which the client participated before is brought into registered state (S 9 ). The procedure returns to S 8 , and the processes thereafter are repeated. When the judgment is made at S 8 that the channel in which the client does not participate does not remain, the access process is terminated, and the procedure returns to the source of access.

FIG. 5 is a flow chart showing a procedure for transmitting the attribute information (S 2 in FIG. 3 ). When the participation in and registration at the channel of the client based on the aforementioned access procedure is completed, the chat server acquires the attribute information of the channels at which the respective clients register and transmits the attribute information to corresponding clients (S 11 ).

Next, a judgment is made as to whether or not the access state of each client to the chat server is continued (S 12 ). When the judgment is made that the access state is continued, a judgment is made as to whether or not an event (for example, setting of topics, changing of a channel mode, new participation, etc.) relating to the change in the attribute information by means of operation by users participating in the channel is received (S 13 ). When the event is received, the attribute information of the channel is acquired to be transmitted (S 14 ). When the judgment is made at S 12 that the access is not continued, the processing procedure is terminated. When the judgment is made at S 13 that the event is not received, the procedure returns to S 12 , the processes thereafter are repeated.

FIG. 6 is an explanatory drawing showing one example of a display screen of the client. An area in the lower right portion in the drawing is a window W 1 on which names and attribute information of channels are displayed. The window W 1 is provided with, in order from left, an icon area W 1 a on which icons representing channel modes are displayed, a channel name area W 1 b on which names of channels are displayed, a number of users area W 1 c on which a number of clients registering at a channel is displayed, a topic area W 1 d on which topics are displayed, and a mode area W 1 e on which channel modes are displayed.

In the icons displayed on the icon area W 1 a , a design of a coffee cup represents that a channel mode is not set. Moreover, a design of an exclamation mark “!” represents that a secret mode is set. Further, on the mode area W 1 e “+s” represents a secret mode. Further, “+i” represents an invite only mode, and “+k” represents a channel key mode.

FIG. 7 is a flow chart showing a procedure (S 2 in FIG. 3 ) for transmitting a number of times and amount of statements (more specifically, a number of characters used for statements) in the chat server. A command for generating a channel is received from a client, and the channel is generated (S 21 ).

Next, a judgment is made as to whether or not a channel presents (S 22 ), and when a channel presents, a judgment is made as to whether or not a statement is received from a client of user who participates in the channel (S 23 ). When the statement is received, a number of times and amount of statements including statements on that day are counted (S 24 ), and the counted result or a predetermined image corresponding to the counted result or information which designates the image (for example, a name of an image file) is transmitted to the clients of all the users who register at the channel (S 25 ). When the judgment is made at S 22 that a channel does not present, the processing procedure is terminated. When the judgment is made at S 23 that the statement is not received, and the process at S 25 is terminated, the procedure is returned to S 22 , and the processes thereafter are repeated.

FIG. 8 is an explanatory drawing showing one example of the display screen of the client. An area on the lower right portion in the drawing is a window W 2 on which names of channels, and a number of times and amount of statements are displayed. The window W 2 is provided with, in order from the left, an icon area W 2 a on which icons representing number of times of statements are displayed, a channel name area W 2 b on which names of channels are displayed, a member of users area W 2 c on which a number of clients registering at a channel is displayed, a number of times of statements area W 2 d on which a number of times of statements is displayed, and a statement amount area W 2 e on which an amount of statements is displayed.

In the icons displayed on the icon area W 2 a , a design of a coffee cup represents that a number of times of statements in a channel is small. Moreover, a balloon-shaped design represents that a number of times of statements in a channel is large. Here, a predetermined threshold value is used for discriminating the number of times of statements.

FIG. 9 is a flow chart showing a procedure (S 4 in FIG. 3 ) for changing a channel. When an event is received, a judgment is made as to whether or not the event is an event for designating a registered channel displayed on the display screen (S 31 ). When the judgment is made that the received event is such an event, a request to change the channel is transmitted to the chat server so that the channel is replaced with a channel where statements are possible (S 32 ). Then, the process for changing the channel is terminated and the procedure is returned to the source of the access, When the judgment is made at S 31 that the received event is not the event for designating another channel, another event process, for example, a judgment is made as to whether or not the received event is an event for commanding to terminate the processing procedure of the chat system (S 33 ), and the procedure is returned to the source of access.
