We present a new visualization approach for metadata combining different visualizations into a so-called SuperTable accompanied by a Scatterplot. The goal is to improve user experience during the information seeking process. Our new visualizations are based on our experiences developing a visual information retrieval system called INSYDER to supply small and medium size enterprises with business information front the Internet. Based on extensive user tests the original visualizations have been redesigned in two different design variants. Instead of offering multiple visualizations to choose front the SuperTable + Scatterplot combines them in a new way. Therefore, the user has the feeling that he is working with one single visualization in different states. Further the SuperTable solves a problem which seemed to be immanent to visualization's in document retrieval: the change of modalities.

The literature on information visualization establishes the usability of interfaces with an overview
of the information space, but for zoomable user interfaces, results are mixed.We compare zoomable
user interfaces with and without an overview to understand the navigation patterns and usability
of these interfaces. Thirty-two subjects solved navigation and browsing tasks on two maps. We
found no difference between interfaces in subjects? ability to solve tasks correctly. Eighty percent
of the subjects preferred the interface with an overview, stating that it supported navigation and
helped keep track of their position on the map. However, subjects were faster with the interface
without an overview when using one of the two maps. We conjecture that this difference was due
to the organization of that map in multiple levels, which rendered the overview unnecessary by
providing richer navigation cues through semantic zooming. The combination of that map and the
interface without an overview also improved subjects? recall of objects on the map. Subjects who
switched between the overview and the detail windows used more time, suggesting that integration
of overview and detail windows adds complexity and requires additional mental and motor effort.
