摘要：The development of Internet technologies and computer devices make it possible to move communication space from the real world to virtual worlds. Thus, there is an increasing need for virtual communication or virtual collaboration tools which enable users to communicate or work with others in virtual space wherever and whenever. In this paper, we propose an Internet-based virtual collaboration system supporting multimedia presentation. The proposed system provides two main functions. One is a content authoring function for creating multimedia presentation and the other is a virtual collaboration function for offering conferences that helps users exchange their opinions. The authoring function uses Synchronous Multimedia Integration Language (SMIL) that integrates and synchronizes media objects such as text, images, and video. While making a multimedia content, text or drawing can be used as annotations over images in layered architecture. In virtual collaboration, users can use digital images and spatial data elements which are used to represent users' opinions and areas of interest in images. From conferences, users' opinions along with coordinate information can be stored into XML database using Unstructured Information Management Architecture (UIMA).
