Abstract
This paper briefly describes several first- and second-generation virtual environment (VE) systems, and the results of US Army empirical testing of one second-generation system - the CAVE Automatic Virtual Environment (CAVE). Compared in the test with the CAVE was the Army's traditional and proven method of reviewing advanced vehicle concepts - a PowerPoint™ briefing. Test results indicated several advantages for the VE that should be of interest to any organisation facing the need to shrink development life cycles, reduce costs, and improve product and system utility. A conclusion reached is that additional research and testing are needed to provide additional insights into the use of VE technologies to improve and support collaborative product and system development, design, and acquisition.
