The Circlesegmentview: a User Centered, Meta-data Driven Approach for Visual Query and Filtering Dr. Peter Klein

Some of the main challenges of the Web are problems related to the user and his interaction with an information-retrieval system. People with different educational, social, cultural and economic backgrounds use the Internet to gather information or to search for knowledge. Information-seeking systems like Web Search Engines should help the users with this task. The information-seeking process is covered in computer science by various fields of research like Usability Engineering, Information Visualization or Information Retrieval. The development of a visualization called 'CircleSegmentView' (CSV) will demonstrate the user centered design process of such an information seeking system. The purpose of this visualization is to serve as a dynamic query interface for a system called VisMeB (Visual Meta-data Browser), which is engineered at the Human-Computer Interaction workgroup at the University of Konstanz (Germany).
