Abstract:
This paper presents a system for collaborative design applications
based on distributed augmented reality. Augmented reality interfaces
are a natural method for presenting computer-based design by merging
graphics with a view of the real world. Distribution enables users at
remote sites to collaborate on design tasks. The users interactively
control their local view, try out design options, and communicate
design proposals. They share virtual graphical objects that substitute
for real objects which are not yet physically created or are not yet
placed into the real design environment.
We describe the underlying augmented reality system and how it has been extended in order to support multi-user collaboration. The construction of distributed augmented reality applications is made easier by a separation of interface, interaction and distribution issues. An interior design application is used as an example to demonstrate the advantages of our approach.
