Towards Visual User Interfaces Supporting Collaborative Multimedia Content Management.

Exploring and searching multimedia content over multiple distributed databases poses specific new challenges for the design of cognitively efficient and at the same time task effective user interfaces. To overcome these problems, advanced 3D graphical presentation techniques can support interactive exploration and analysis functionality for multimedia material. Therefore, techniques enabling the dynamic generation of 3D information visualizations of queries on multimedia data collections, as well as 3D information visualizations of the corresponding results sets for these queries have to be developed. This has to be achieved in a cognitively efficient way, meaning that elements of such result sets can be easily presented, explored, and analyzed, e.g., with respect to their relation to the query or even in the context of users\' tasks, as well as information and knowledge profiles. Furthermore, the exploration of multimedia collections can benefit from, e.g., the possibility of presenting multimedia content in abstract information landscapes, where multimedia objects are collocated in such a way that their spatial relations are indicative of their relations with respect to their content or other properties of the multimedia objects. In addition, the application of visually-direct-manipulative relevance feedback mechanisms to support search and browsing activities can improve the information dialogue.
