The present invention relates to techniques for supporting organizational, labeling and retrieval tasks on an electronic tabletop, wall or large display. In various embodiments of the invention, a dynamic visualization is used to show a current working set of documents. In an embodiment of the invention, the rest of the collection is represented in the background as small dots. In an embodiment of the invention, when a user moves objects into groups or creates a label, relevant objects in the background are automatically retrieved and moved into the foreground. In an embodiment of the invention, retrieved objects along with relevant objects in the current set are highlighted and decorated with arrows pointing to their relevant groups. In an embodiment of the invention, the movement is animated to provide user feedback when objects must travel long distances on a large display.
