LORNAV: A Demo of a Virtual Reality Tool for Navigation and Authoring of Learning Object Repositories

Navigation in 3D world has reached its pinnacle with the advent of several technologies like JAVA, XML, WEB SERVICES, VRML, X3D etc. A lot of efforts have been given to visualize and navigate in virtual mall, cities, digital libraries etc. Most of them visualize only static objects. We designed a Virtual Reality (VR) Tool, called Learning Object Repository Navigation and Authoring in Virtual environment (LORNAV) that extracts Learning Object Metadata (LOM) dynamically from repositories and creates 3D representation of these objects. The proposed tool provides several facilities such as personalized navigation allowing a user to view content that is of interest to him. It also helps users to create new aggregated Learning Objects (LOs) from existing ones in a 3D Environment to be presented in SMIL format.
