We developed a prototype system for graphical drawings on Web browsers using Asynchronous JavaScript and XML (AJAX) techniques. The system allows multiple participants to share multiple pointers and to simultaneously add graphical drawings onto a Web page. All the participants can see all telepointers and graphical drawings in real-time. They only need a normal Web browser and installation of special software such as plugins is not required to share the telepointers and graphical drawings. Since the Web browser communicates with a server through conventional HyperText Transfer Protocol (HTTP) connections, telepointers and graphical drawings can be widely shared without communications being prevented by network firewalls. Various methods of optimization are also discussed in the paper.
