Techniques that are already known and proven are combined in a way that emphasizes the advantages and eclipses the drawbacks of individual features. For this purpose Multiple Coordinated Views and a Granularity Concept based on the idea of a semantic zoom were unified. The approach is not restricted to a specific domain and the visualizations used can be easily adapted. The concept is implemented within the VisMeB framework, a Java-based "Visual Metadata Browser" that is available in diverse versions.<br />Two main disciplines guide this thesis - Information Visualization and Usability Engineering. Thus, the presented work adheres to this division. The first part of the thesis deals with Information Visualization in general and gives an overview of the interaction techniques used and applications that provided inspiration. This progresses to a detailed description of the multiple coordinated views implemented and the granularity concept.<br />Because the use of multiple coordinated views offers advantages as well as drawbacks, it is necessary to clarify a) whether to use them at all, b) if yes, which visualizations to choose, and c) how the layout and the interaction are defined, which leads to the three-phase model introduced and described in this work the first time. Furthermore, three differently-implemented granularity versions are introduced - the TableZoom, the RowZoom, and the CellZoom, which have a strong influence on the display and user interaction. A detailed description of interaction techniques between the multiple coordinated views subject to the granularity concept closes the first part of the thesis.<br />The second part deals with Usability Engineering or, more precisely, the User-Centered Design Process. The development of VisMeB follows the user-centered design process, which results in early user tests that are responsible for important design decisions. This leads to an enormous advantage compared to systems that did not involve users during the development. After an introduction into the field of usability engineering, the different development steps of VisMeB are considered. Prototyping played an important role and, in combination with user tests, the design process was guided by the results of these investigations.<br />An outlook and a conclusion brings this thesis to a close. deposit-license Müller, Frank application/pdf
