Seamless interconnection of distributed virtual worlds
Ioannis Kotziampasis, Alan G. Chalmers · 2007
Multi-user virtual environments implemented across the web allow many users to interact with the virtual world and each other in. The current standard for embedding virtual worlds in the Internet, VRML 2.0, provides links between these worlds, but it does not allow the user to see across these links before physically entering them. This paper describes the use of portals to connect the distributed virtual environments in a way that the interconnected virtual environment will be visible from different machines. A psychophysical study is presented which investigates user navigation in consistent and inconsistent virtual environments using portals compared to traditional VRML Anchor based hyperlinks.
