Scene Synchronization for Distributed Collaborative Augmented Reality Environment in the Access Grid

摘要

The Access Grid (AG) is one of the most widely used technologies for building advanced collaborative environment, and a distributed collaborative Augmented Reality (AR) environment has been established with AG and AR technologies. In such distributed shared environment, one of the most difficult tasks is maintaining a consistent view of the shared AR scene among all participants. This paper presents a scene synchronization method to support the management of composite scene elements and the synchronization of the view in the shared scene and heterogeneous users' manipulations cooperating within a shared context After presenting this method, this paper describes its use in a prototype application, and results show that this method can properly synchronize the dynamic shared scene, providing the users with a unified view of their activities in multiple collaboration spheres.
