Abstract

A selectable three dimensional virtual pointer (501) that can be selected by a collaborator and displayed within a virtual collaboration environment (200) as being sourced by an avatar (202) that corresponds to the collaborator who selected the pointer. This pointer can be used, for example, to point towards a given object (205) within the virtual collaboration environment. So configured, in a preferred approach this orientation with respect to source and target persists regardless of which collaborator views the pointer (and hence the perspective view of the pointer varies with respect to the viewer in order to ensure this orientation).

Claims

1. A method for use with a virtual collaboration environment having a plurality of participating avatars representing participants at a plurality of locations with each avatar displayed in its respective environmental perspective and each participant viewing the virtual collaboration environment from a unique perspective of its avatar and at least one object, the method comprising the steps of:

providing a selectable three dimensional virtual pointer;

detecting selection of the selectable three dimensional virtual pointer by a first collaborator;

displaying the selectable three dimensional virtual pointer as being sourced by a given one of the plurality of participating avatars as corresponds to the first collaborator and which points to an object.

2. The method of claim 1 wherein providing a selectable three dimensional virtual pointer comprises providing a plurality of selectable three dimensional virtual pointers.

3. The method of claim 2 wherein the plurality of selectable three dimensional virtual pointers are visually distinct from one another.

4. The method of claim 3 wherein the plurality of selectable three dimensional virtual pointers are visually distinct from one another with respect to color.

5. The method of claim 2 wherein providing a plurality of selectable three dimensional virtual pointers comprises providing at least one selectable three dimensional virtual pointer for each of the plurality of participating avatars.

6. The method of claim 1 wherein the selectable three dimensional virtual pointer has an arrow-shaped form factor.

7. The method of claim 1 wherein detecting selection of the selectable three dimensional virtual pointer by a first collaborator further comprises detecting selection of the object as a pointing target.

8. The method of claim 7 wherein detecting selection of the object as a pointing target further comprises:

detecting collaborator manipulation of a user input device;

adjusting the pointing target as a function, at least in part, of the collaborator manipulation of the user input device.

9. The method of claim 8 wherein adjusting the pointing target comprises adjusting a position of the pointing target within the virtual collaboration environment.

10. The method of claim 7 wherein detecting selection of the object as a pointing target further comprises automatically snapping to the object.

11. The method of claim 10 wherein snapping to the object further comprises following a surface of the object by continuously snapping to the object as the three dimensional virtual pointer is moved across the object.

12. The method of claim 7 wherein detecting selection of the object as a pointing target further comprises locking the pointing target such that when a source of the three dimensional virtual pointer is moved, the pointing target remains unchanged.

13. The method of claim 1 wherein displaying the selectable three dimensional virtual pointer as being sourced by a given one of the plurality of participating avatars as corresponds to the first collaborator and which points to the object further comprises displaying the selectable three dimensional virtual pointer as terminating in close proximity to the object.

14. The method of claim 1 wherein detecting selection of the selectable three dimensional virtual pointer by a first collaborator further comprises detecting selection of a three dimensional virtual pointer source location and wherein displaying the selectable three dimensional virtual pointer as being sourced by a given one of the plurality of participating avatars further comprises displaying the selectable three dimensional virtual pointer as being sourced from the three dimensional virtual pointer source location.

15. The method of claim 1 further comprising:

detecting modification of the selectable three dimensional virtual pointer into a virtual object grabber;

moving the object as a function, at least in part, of manipulation of the virtual object grabber.

16. An apparatus comprising:

a display that provides a display of a virtual collaboration environment having a plurality of participating avatars representing participants at a plurality of locations with each avatar being displayed in its respective environmental perspective and each participant viewing the virtual collaboration environment from a unique perspective of its avatar and at least one object;

a collaborator-selectable three dimensional virtual pointer;

a collaborator interface operably coupled to the display and the collaborator-selectable three dimensional virtual pointer and being configured and arranged to respond to selection of the collaborator-selectable three dimensional virtual pointer by a first collaborator by facilitating the display of the collaborator-selectable three dimensional virtual pointer as being sourced by a given one of the plurality of participating avatars as corresponds to the first collaborator and which points to a given object which the first collaborator has identified to be pointed towards.

17. The apparatus of claim 16 wherein the collaborator-selectable three dimensional virtual pointer comprises a plurality of collaborator-selectable three dimensional virtual pointers.

18. The apparatus of claim 16 wherein the collaborator interface comprises means for detecting selection of the given object as a pointing target.

19. The apparatus of claim 18 wherein the means for detecting selection of the given object as a pointing target further comprises at least one of:

means for adjusting the pointing target as a function, at least in part, of

collaborator manipulation of a user input device; and

means for automatically snapping to the given object.

20. The apparatus of claim 16 further comprising:

means for detecting modification of the selectable three dimensional virtual pointer into a virtual object grabber and for moving the given object as a function, at least in part, of manipulation of the virtual object grabber.
