A specific metaphor for Private Point of View

Participants : Johann Vandromme, Samuel Degrande, Nicolas Martin, Patrica Plénacoste, Luciana Provenzano.

In some collaborative activities, such as the manipulation of complex objects, different users can work on distinct parts of a shared object. This implies that each user has her own viewpoint on the object. Viewpoint awareness is then necessary both to coordinate each other and to understand remote users' activity during the execution of the collaborative task. We propose a combination of several metaphors to provide a remote viewpoint awareness in a 3D collaborative desktop in which multiple shared objects can be independently positioned and manipulated [32] .
