Abstract

A system for visualizing information in multi-display environments (“MDEs”) using spatial and perspective-aware visualization techniques. In one implementation, the position of each display in a three-dimensional MDE is determined relative to the other displays. Graphical decoration objects and link paths are then used to help visualize relatedness and continuity between graphical data objects and graphical node-link objects on different displays. Three-dimensional decoration objects and link paths are also constructed to visualize interrelationships between data objects on displays that are not on the same plane. The visualization techniques can also be integrated with mobile displays using location sensing technology to dynamically adjust the decoration objects. Additionally, user tracking systems will dynamically adjust the decoration objects based on user perspective. The visualization techniques are applicable to physical, virtual or mixed physical-virtual environments.

Claims

1. A system for visualizing information in a multi-display environment, the system comprising:

a multi-display environment (“

MDE”

) comprising a plurality of displays arranged in different planes within a three dimensional (“

3D”

) space, the plurality of displays operable to display a plurality of graphical data objects arranged on the MDE;

a coordinate determination module operable to determine a position of each of the plurality of displays and to use the determined position of each of the plurality of displays to calculate a position of each of the plurality of graphical data objects; and

a placement module for placing a plurality of graphical decoration objects with direction-indicating properties on the plurality of graphical data objects, the plurality of graphical decoration objects illustrating interrelationships of the graphical data objects in the plurality of displays.

2. The system of claim 1, wherein the MDE is a physical environment.

3. The system of claim 1, wherein the MDE is a virtual environment.

4. The system of claim 1, wherein the MDE is a mixed physical-virtual environment.

5. The system of claim 1, wherein the graphical decoration objects comprise 3D shapes.

6. The system of claim 5, wherein the 3D shapes comprise arrows.

7. The system of claim 1, wherein at least one of the plurality of displays is a mobile display.

8. The system of claim 7, further comprising a tracking module operable to track a location of the at least one mobile display.

9. The system of claim 1, further comprising a positioning module operable to position the graphical decoration objects in relation to a perspective of a user viewing the MDE.

10. The system of claim 9, further comprising a user tracking module operable to track the position of the user relative to the MDE.

11. The system of claim 1, wherein the interrelationships of the graphical data objects are determined based on the similarity of text, metadata or image features of the graphical data objects.

12. The system of claim 1, wherein a graphical data object is interrelated with a cluster of graphical data objects and wherein the cluster is detected by a clustering algorithm.

13. A system for visualizing information in a multi-display environment, the system comprising:

a multi-display environment (“

MDE”

) comprising a plurality of displays arranged in different planes within a three dimensional (“

3D”

) space, the plurality of displays operable to display a plurality of graphical node-link objects arranged on the MDE;

a coordinate determination module operable to determine a position of each of the plurality of displays and to use the determined position of each of the plurality of displays to calculate a position of each of the plurality of graphical data objects; and

a placement module for placing a plurality of graphical connector objects with direction-indicating properties on the plurality of graphical node-link objects at a point where a link object extends beyond an edge of one of the plurality of displays, the plurality of graphical connector objects illustrating interrelationships of the graphical data objects in the plurality of displays.

14. The system of claim 13, wherein a pair of graphical connector objects comprise distinctive visual matching properties.

15. The system of claim 13, wherein the graphical decoration objects comprise 3D shapes.

16. A method for visualizing information in a multi-display environment, the method comprising:

displaying a plurality of graphical data objects on a plurality of displays in a multi-display environment (“

MDE”

), wherein the plurality of displays are arranged in different planes within a three dimensional (“

3D”

) space;

determining a position of each of the plurality of displays and a position of each of the plurality of graphical data objects in the MDE in relation to the arrangement of the plurality of displays; and

placing at least one graphical decoration object on at least one of the plurality of graphical data objects, the graphical decoration objects each having a direction-indicating property operable to illustrate interrelationships of the plurality of graphical data objects on the plurality of displays.

17. The method of claim 16, further comprising selecting 3D shapes as the graphical decoration objects.

18. A method for visualizing information in a multi-display environment, the method comprising:

displaying a plurality of graphical node-link objects on a plurality of displays in a multi-display environment (“

MDE”

), wherein the plurality of displays are arranged in different planes within a three dimensional (“

3D”

) space;

determining a position of each of the plurality of displays and a position of each of the plurality of graphical node-link objects in the MDE in relation to the arrangement of the plurality of displays; and

placing at least one graphical connector object on at least one of the plurality of graphical data objects at a point where a link object extends beyond an edge of one of the plurality of displays, the graphical connector objects each having a direction-indicating property operable to illustrate the interrelationships of the plurality of graphical node-link objects on the plurality of displays.

19. The method of claim 18, further comprising providing distinctive visual matching properties on the graphical connector objects.

20. The method of claim 18, further comprising selecting 3D shapes as the graphical decoration objects.
