Improving information access by visualizing visited hypertext pages
My diploma thesis. The original title is “Unterstützung des Zugriffs auf Informationen mittels Visualisierung besuchter Hypertextseiten”
Information visualization and interaction
A term paper on information visualization and interaction
A primer on Information Visualization.
Amongst others, topics covered in this paper include the visualization process (filtering, mapping, rendering, and usage of data), the distinction between data and information, as well as graph and network theory.
The later chapters focus on interaction and interface techniques and introduce the concepts of zoom + pan, focus + context, and other, more innovative visualization methods (e.g. TreeMap, fisheye and hyperbolic views).
Finally, the paper evaluates some products and projects, such as Cone Tree, Perspective Wall, and the well-known Map of the Market.
NetMapper
Cartography tool to visualize internet structures
NetMapper visualizes the intrinsic structures of the net as composition of objects in spatial space. The links between resources are examined and stored with further informations such as link depth or resource names. Finally NetMapper creates a VRML-view through which the user can navigate. Thus the user learns the structure by analyzing this view.
