ADAPTIVE WEB3D VIRTUAL LEARNING ENVIRONMENT USING INTEREST MANAGEMENT

摘要

Virtual Learning Environment (VLE) is a computer-based online learning environment, which provides opportunities for geographically distributed student to learn at the time and location of their choosing. Especially the Web3D VLE can bring us more rich learning experience as well as the information overload and low adaptive for the huge of 3D data. In this paper, we propose prototype of adaptive Web3D VLE with interest management supported, named VLE-IM. VLE-IM provides the interest management methodology with correlation analysis, the description of the correlation interest scheme using digraph. System can filter the update message and network traffic using Web3D Level-of-Detail(LOD) control based on Xj3D and Java programming language. JXTA technology based architecture can accommodate prototype system with centralized/decentralized mode and high scalability. Incorporated with these approach, VLE-IM meets the request of adaptive Web3D VLE. Besides; some development issues are address in this paper.
