A Web-Based Virtual Collaboration System in Multiple Conferences

We are proposing the web-based virtual collaboration system where multiple users are collaborated dispersed in locally and timely by the Internet. The proposed system categorizes users by the interested conference and each user is restricted to access the system resources by the access control. Any users can crate new topics or join the existing topics by validating user's access right freely in a conference they belong. Users can participate in more than one topic simultaneously, so they can inquire and get a valuable knowledge on-line in one topic and participate in the other topic more informed and intelligently. They can also save time by attending multiple topics at the same time. Conferences are performed by using power point slides and associated spatial data elements from the participants. Associated spatial data elements can be symbols such as arrows or polygons along with text. The content of each conference spatial data elements from the participants with respect to certain topic can be recorded into an XML file and archived for future reference.
