Subject: Re: DESIGN: VR Interaction Mechanisms
Organization: Collaborative Information Technology Research Institute

We have built an application called VR Designer which is used for
architectural design. The application is built on top of a framework
specifically designed to support intuitive simple interaction. The
framework is called PHIVE, (PHysically-based Interaction in Virtual
Environments), it supports real-time collision detection of concave
polygonal objects, rigid body motion, sound, protocols for
multi-person operation etc.

PHIVE is described in the paper:

Gigante, M., Webb, R.
"Distributed, Multi-Person, Physically-Based Interaction in Virtual
Environments"
Proceedings of Computer Graphics International '93 
(Ed: Daniel Thalmann, Publisher: Springer Verlag, Tokyo)
Lausanne, Switzerland

The main premise is that behavioural realism is a key to natural,
interaction that has low cognitive overheads.
