Proceedings, ACM CHI Conference, 1995. As for querying, further problems come from the need to deal with imprecise and vague queries. Based on Hyperbolic Geometry for Visualizing Large Hierarchies . Human Factors in Computing Systems, pages 401-407, 1995. This theory is reinforced by our experiment, described below.
Users can drag the display in any direction to bring nodes from the edge towards the center.
Individual nodes can be single clicked to show their titles, or double clicked to bring that document up in the Web browser. This representation was chosen because it deals well with the highly nonplanar and highly disconnected graphs produced by our interaction histories. Lamping et al. Koike s work was also used directly on viewing source code. John Lamping, Ramana Rao, and Peter Pirolli.
