Abstract
A partially collapsing hierarchical display system aids information navigation by providing a dynamic mechanism for labeling items with one or more states. In one embodiment, states comprise “hidden”, “visible” and “unmarked”. An expanded list of items displays all items. A partially expanded list of items displays all visible and unmarked items, removing hidden items from the display. A further collapsed list of items displays all visible items. A completely collapsed list of items hides all items. Users customize the amount of detail displayed in a sub-tree, reducing the display size of the sub-tree. Expansion of a hierarchical structure is combined with filtering, allowing users to partially collapse or partially expand a sub-tree structure. Partially collapsed lists comprise one or more focus points, allowing users to view several relevant sections of a hierarchical structure concurrently. Displayed sizes or other visual characteristics of items within the hierarchical structure are automatically adjusted to reflect the states designated by the user.
