Abstract:
This paper introduces an information visualization
component that appears as an additional window in an
online collaborative e-learning environment, and can
be used for viewing, browsing, editing and
manipulating knowledge-based learning information
through the LiveNet [9] - a knowledge management
and enterprise collaboration tool. This visual
component employs a new visualization technique,
called ENCCON [7], which uses a connection +
enclosure layout method and a semi-transparency
navigation mechanism to handle large scale of
hierarchical learning information and it aims to
provide a better assistance to the users of LiveNet for
visual manipulation and navigation of knowledge-based
data objects. The use of visualization techniques
in LiveNet provides users with not only a 2D graphical
visual interface for direct data manipulation, but also
a set of clear views, the focus+context views, of the
interrelations among the data objects which enhances
the understanding of relational information that the
users want to see. Although the proposed visualization
technique ENCCON can be applied in many domains,
we only concern its application in the domain of
collaborative e-learning through the LiveNet.
