To provide a collaboration system and its chat system wherein a chat can be conducted by designating clearly and simply a position of an object to be noticed in a working image. [Constitution] A plurality of terminal devicesand a chat serversupporting a chat are provided. By managing a display position, on a display screen, of a chat window for performing a chat in the terminal devicesand the chat server, display positions of chat windows are synchronized between the terminal devicesthat conduct a chat. The chat window is displayed correspondingly to a given element displayed on the display screen.

Collaborative chat system

The present invention provides a collaboration system that reduces communication traffic, is platform- and OS-independent, and has high versatility. There are provided a collaboration server connected with a plurality of terminal apparatuses through a network for obtaining, retaining, and distributing a Web page as a work screen used in collaborative work among the terminal apparatuses, and a chat server for managing chat sessions. The collaboration server participates as a chat client in a chat session managed by the chat server and distributes an operation instruction concerning the work screen as a chat message to each terminal apparatus. The work screen is reloaded into each terminal apparatus according to the operation instruction to allow the collaborative work to progress.

An information terminal connected to one of a plurality of servers which are allocated by a dispatcher is connected to another information terminal via its allocated server. When a Web Browser is connected to a Web Server via a Dispatcher , a content including a button for requesting the agent side for connection is displayed in the web screen. When the customer clicks this button, a customer ID and an IP address of the server are stored in a table . After a CTI Server allocated an agent, an Agent proxy obtains an IP address corresponding to the customer to be connected and accesses to the server

System for coordinating communication between a terminal requesting connection with another terminal while both terminals accessing one of a plurality of servers under the management of a dispatcher
