Abstract

The present invention is a system that manages a volumetric display using volume windows. The volume windows have the typical functions, such as minimize, resize, etc., which operate in a volume. When initiated by an application a volume window is assigned to the application in a volume window data structure. Application data produced by the application is assigned to the windows responsive to which applications are assigned to which windows in the volume window data structure. Input events are assigned to the windows responsive to whether they are spatial or non-spatial. Spatial events are assigned to the window surrounding the event or cursor where a policy resolves situations where more than one window surrounds the cursor. Non-spatial events are assigned to the active or working window.

Claims

1. A method of managing a volumetric display having three physical dimensions, comprising:

creating one or more volume windows each having three physical dimensions in the volumetric display; and

providing application data to the windows corresponding to one or more applications assigned to each of the windows.

2. A method as recited in claim 1, wherein the windows are delimited by visible boundaries.

3. A method as recited in claim 1, wherein the volume windows have a shape comprising one of cubic, cylindrical, pie wedges, irregular or spherical.

4. A method as recited in claim 1, wherein input events are assigned to one of the windows responsive to input focus.

5. A method as recited in claim 4, wherein input focus comprises the window enclosing the cursor for spatial input events and the active window for non spatial input events.

6. A method as recited in claim 1, wherein the windows have window functions comprising one of open, close, resize, maximize, minimize, move, or hide.

7. A method as recited in claim 6, wherein the open function allocates three-dimensional region within the display for an application having an origin and highlights a three-dimensional boundary of the region the further comprising display outputs of the application in the region, and sending all the cursor events to the application when a cursor is within the region.

8. A method as recited in claim 6, wherein the minimize function substitutes a three-dimensional icon for a designated volume window and places icon at a designated position within the display.

9. A method as recited in claim 6, wherein the maximize function expands a designated volume window until the window contacts a boundary of the display and scales contents of the volume window in proportion to the change in volume.

10. A method as recited in claim 6, wherein the move function moves a three-dimensional volume window in accordance with a three-dimensional motion vector.

11. A method as recited in claim 6, wherein the resize function determines whether an active window encounters an inactive window in three dimensions.

12. A method as recited in claim 1, wherein application requests are mapped to corresponding windows responsive to the window assigned to the application.

13. A method as recited in claim 1, wherein an active window having a size can have the size changed and the method comprising resizing a window that abuts the active window responsive to the change in size of the active window.

14. A method as recited in claim 1, wherein the user can designate volumes or sub-volumes using gestures.

15. A method of managing a volumetric display having three physical dimensions, comprising:

creating volume windows each having three physical dimensions within a volumetric display; and

associating a process with each of the volume windows.

16. A computer readable storage controlling a computer by creating one or more volume windows having three physical dimensions in a volumetric display having three physical dimensions, and providing application data to the windows corresponding to one or more applications assigned to each of the windows.

17. An apparatus, comprising:

a volumetric display apparatus having a volumetric display having three physical dimensions;

an input system producing input events; and

a computer creating volume windows having three physical dimensions within the display, assigning application data to the windows responsive to applications assigned to the windows, and assigning input events to the windows responsive to input focus.

18. A display, comprising:

a volumetric display space having three physical dimensions; and

a volume window positioned in the display space and having a physical three-dimensional boundary.

19. A display as recited in claim 18, wherein the volume window has a title bar indicating a window orientation and a front of the volume window.

20. A method of managing a volumetric display having three physical dimensions, comprising:

creating a volume window having three physical dimensions in the volumetric display; and

displaying information in the volume window.

21. A display, comprising:

a volumetric display space having three physical dimensions; and

a volume window having three physical dimensions positioned in the display space and displaying data.

22. A display, comprising:

a volumetric display space having three physical dimensions; and

a volume menu bar having three physical dimensions positioned in the display space and displaying menu items.

23. A display, comprising:

a volumetric display space having three physical dimensions; and

a volume icon having three physical dimensions positioned in the display space and initiating a function when activated.
