Chatting Module Design in Online Virtual Campus System

In this paper, we present a new method to design and realize chatting module in online virtual campus system. Our virtual campus system is based VRML (Virtual Reality Modeling Language) and JavaScript, and has two parts, including server and client. We divide the system into several different modules, including user interface, models database, information database, navigation graph, chatting module and server module. In order to meet all the demands of students and professors, we offer three chatting modes, including public chatting, regional chatting, and private chatting. In this way, the students and professors can use different modes to achieve different functions. Certainly, we also design the chat panel for students and professors. We have implemented our method and our system is running smoothly.
