In this paper, an implementation of a virtual chat room system for multimedia communications is presented. In addition to the conventional ability of chat room applications to transmit talk messages between users, the system provides a 3-D virtual environment and adopts 3-D facial models for character representation. Each participant can communicate with the others with keyboard, mouse, and his facial expressions. Essential implementation issues including the facial expression analysis process are detailed in this article.
