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.
