Navigation in a 3D world has reached its pinnacle with the advent of several technologies like Java, XML, Web services, VRML, X3D, etc. Much effort has been given to visualizing and navigating in virtual mall, cities, digital libraries etc. We designed a virtual reality (VR) tool, called Learning Object Repository Navigator (LORNAV) that extracts learning object metadata (LOM) dynamically from distributed repositories, creates 3D representation of these objects and displays them in a 3D environment using several visualization metaphors. The proposed tool allows the user to navigate through the 3D environment, view the associated metadata of the 3D objects, read/play the content, and select the objects of interest to create a personal space within the 3D environment. The creation of personal space provides users with a familiar navigation space consisting of learning objects of their choice.
