Interconnected media for human-centered understanding

Today, there are many systems with large amounts of complex data sets. Visualizing these systems in a way that enlightens the user and provides a profound understanding ofthe respective information space is one of the big information visualization research challenges. Keim states that it is no longer possible to display an overview of these systems as proposed in Shneiderman's information seeking mantra. To overcome this incapacity and to provide a solution to the dilemma of time multiplexing- vs. space multiplexing techniques, we propose the context-sensitive use of a collection of animated 3D metaphors. These metaphors are integrated in a flexible framework called HANNAH. This provides the possibility to interconnect media of various types in order to bridge the semantic gab as required for human-centered applications according to Elgammal.
