Navigation and interaction in structured information spaces

摘要

A method and system for generating an interactive, multi-resolution presentation space of information structures within a computer enabling a user to navigate and interact with the information. The presentation space is hierarchically structured into a tree of nested visualization elements. A visual display is generated for the user which has a plurality of iconic representations and visual features corresponding to the visualization elements and the parameters defined for each visualization element. The user is allowed to interact in the presentation space through a point of view or avatar. The viewing resolution of the avatar is varied depending on the position of the avatar relative to a visualization element. Culling and pruning of the presentation space is performed depending on the size of a visualization element and its distance from the avatar. <IMAGE>
