Abstract: A user interface for business applications provides users a navigable top-down view of a hierarchical structure through a rotating hierarchy cone. The cone presents a partial view of a circularly organized hierarchy of parent and child nodes enabling users to view detail information, select tasks to be performed, and modify the structure while having an overall picture of the hierarchy. Users are enabled to rotate the cone to view an unlimited number of segments of the circularly organized hierarchy and to navigate across multiple levels up or down focusing on branches of the structure.
