virtual environment to share knowledge

Many developments were introduced for presenting§information using digital visualisation techniques,§including 3D interactive visualisations and virtual§environments. Additionally, the way a group of people§shares information about the meanings of concepts can§be considered as an important issue for knowledge§sharing. However, visualisation potential for§representing and exploring knowledge has not yet been§totally explored.§This work proposes a general structure for knowledge§sharing to represent knowledge that allows a group of§users to share concept meanings and their relations,§and to organise information about a specific§knowledge context.§The development and evaluation of a prototype is§presented. An empirical study conducted suggests that§users were able to specify structures for knowledge§sharing, using the prototype to explore and enhance§the structure. The prototype can also be used as tool§for collaborative learning.§The work offers a structured approach to how 3D§visual representations, as virtual environment§setting, can be used to support collaboration. It§also present how to evaluate them and reports the§algorithms used to the prototype visual rendering§process.
