Navigation through large document spaces, and abstract spaces in general, can be made easier by employing a set of interrelated tools. Based on the assumption that a document space contains both objects and relations, a set of interrelated tools that are currently being tested and refined using the CASCADE testbed. Currently four tools -- Docuverse, Webview, Landmarks, and Preview -- are being used. It appears that each tool will play a role at different times in the navigation process. The tools have been linked such that appropriate actions in one tool invoke the other tools allowing the user to zoom in and out, gather detailed data as needed.
As indicated, this work is still in a formative stage of development. Plans for future work include:
