1. A computer controlled display system for displaying document objects in a three-dimensional document workspace on a display, said computer controlled display system comprising:

document retrieval means for retrieving document objects;

a pointer device for pointing a cursor at document objects, said pointer device having a switch with a first up position and a second down position;

positioning means for receiving user input for positioning document objects within said three-dimensional document workspace, said positioning means further comprising;

means for detecting that said cursor is pointing at a selected document object and said switch associated with said pointer device is in said second down position;

circuitry for detecting that said cursor is moved and drawing a line corresponding to the movement of said cursor;

circuitry for detecting that said cursor is pointing at a destination document object and said switch associated with said cursor is in said second up position;

circuitry for performing a context sensitive operation based on said destination document object;

workspace display circuitry for generating display information for displaying said three-dimensional document workspace and said document objects, said workspace display circuitry comprising;

circuitry for displaying a focus space, said focus space for detail display of a document object;

circuitry for displaying an immediate space, said immediate space for ephemeral positioning of document objects that are in use but not in focus; and

circuitry for displaying a tertiary space, said tertiary space for positioning document objects that are not in use.

Abstract

A three dimensional document workspace for interacting with large numbers of document objects. A document object may be a document or a document collection. The document workspace is divided hierarchically in terms of interaction rates. A focus space is where direct interaction with a document or document collection occurs. An immediate memory space is for placing pages or books that are in use, but not currently being interacted with. A tertiary space is where many books and pages that are not in use, but which it is desirable to have ready access to. Moving document objects in the document workspace is facilitated by touch-drop and flick gestures. The touch-drop gesture addresses the problem of obscuring distant (hence smaller) document objects by presenting a visual line indicating a destination for a moved document object. Flick gestures are used to quickly move document objects within the document workspace. A user may change their view of the document workspace in order to view different portions of the workspace in more detail.

- - 2. The computer controlled display system as recited in claim 1 wherein said positioning means is further comprised of flick gesture interpretation means for detecting that a flick gesture has been performed on a document object and re-positioning said document object at a position corresponding to said flick gesture.
  - 3. The computer controlled display system as recited in claim 2 wherein said flick gesture is in an up direction and said re-positioning of said document object is into said immediate space.
  - 4. The computer controlled display system as recited in claim 2 wherein said flick gesture is in a down direction and said re-positioning of said document object is into said focus space.
  - 5. The computer controlled display system as recited in claim 2 wherein said flick gesture is towards a document object representing said tertiary space and said re-positioning of said document objects is into said tertiary space.

6. A method for moving document objects on a computer controlled display system for displaying document objects on a three-dimensional document workspace, said computer controlled display system having a pointer device for controlling a cursor, said pointer device having a switch capable of being in a first up position and a second down position, said method comprising the steps of:
- a) loading said document workspace with documents objects;
  
  b) detecting that a user has selected a first document object using said pointer device and that said switch associated with said pointer device is in said second down position;
  
  c) detecting that said cursor has been moved;
  
  d) visibly tracing the movement of said cursor;
  
  e) detecting that said cursor points to a second document object and that said switch associated with said pointer device is in said second up position; and
  
  f) causing a context dependent operation to be performed based on said second document object.
