Shared Object Interaction in Virtual World

In this paper, we aim to develop tangible collaboration system in virtual world, of which main features include multi-user shared object manipulation and support multi user-interaction device and multi display system (i.e. CAVE and desktop). First, we review the state-of-the-art of virtual worldpsilas research and present comparisons among them in terms of main functionalities. Second, we describe our previous work concerning shared object manipulation in virtual space instead of virtual world. Then, we address the design and implementation of multi-user share object manipulation in virtual world.
