A graphical user interface in which object thumbnails are rendered on a simulated three-dimensional surface which (i) exploits spatial memory and (ii) allows more objects to be rendered on a given screen. The objects may be moved, continuously, on the surface with a two-dimensional input device.

The present invention provides a three-dimensional user interface for a computer system that allows a user to combine and store a group of windows as a task. The image of each task can be positioned within a three-dimensional environment such that the user may utilize spatial memory in order remember where a particular task is located. In further embodiments of the invention, the three-dimensional environment includes a stage, which is used to display the task with the current focus. When a user selects a new task in the gallery, the task is moved to the stage and given focus. If a previous task was on the stage, an image of the previous task is captured. This image is then moved into the task gallery away from the stage. This process allows users to switch between multiple window configurations with a simple action.

A “Spatial Navigator” provides a document navigation environment that leverages user spatial memory. Graphical thumbnail-type representations (“thumbnails”) provide scaled versions of entire documents. Changes to documents are immediately reflected in corresponding thumbnails. Similarly, document search results are highlighted in corresponding thumbnails. One or more dynamic document selection windows present arrangements of a plurality of these thumbnails for user selection and interaction. Each dynamic document selection window provides real-time inter-file navigation by allowing user selection and opening of documents, or any location or portion of a document, through user interaction with the corresponding thumbnail. Once a document is opened, intra-file navigation is enhanced by providing another scaled version of the entire document in a dynamic scrollbar adjacent to a primary document editing/viewing window. Selection of any point within this scrollbar-based thumbnail causes an immediate jump to the corresponding document location in the primary document editing/viewing window.

Techniques are presented for determining a first set of display elements, each display element associated with a first display characteristic. An interesting element in the first set of display elements is determined. A second set of elements related to the interesting element is determined. A third set of elements based on the first and second set of elements is determined using intersection, union, subtraction addition and other logical operations. A third set of elements not yet added to the element collection is determined. The elements in the third set are associated with a second or ghosted display characteristic. The elements in the third set are inserted within the sorted context of the visualization based on spatial distortion rules which help to preserve spatial memory cues in the visualization of the element collection. The elements may be documents in an information repository, linked contact information, linked information records in a database or other types of information.
