LAFAYETTE, La. — (BUSINESS WIRE) — July 31, 2009 — Dr. Carolina Cruz-Neira, Professor of Electrical and Computer Engineering and co-inventor of the CAVE™ Virtual Reality Environment, has incorporated three InFocus® DepthQ® HD 3D Projectors into her design of a new VR Immersion Room that she and her team of researchers built at the University of Louisiana for a collaboration with the Human Research and Engineering Directorate of the U.S. Army Research Lab.

The InFocus® DepthQ® Projectors create stereoscopic HD 3D video images on the walls of the three sided VR Immersion Room while an omni-directional treadmill, which serves as the floor, allows research subjects to travel non-stop in any direction through the virtual reality 3D world. The system was built to create software tools to enable studying the cognitive load on the dismounted soldier (on foot) in highly stressful, rapidly changing scenarios. The goal is to determine what kind and how much information ground troops take in, what distracts them and how they choose which pieces to pay attention to in life and death situations. Dr. Cruz-Neira, and her team, developed the software architecture to create the scenarios in which the soldiers are immersed as well as to collect data from the soldiers through bio sensors and motion capture (

Dr. Cruz-Neira said “We were looking for technology that provides acceptable resolution and image quality at literally one tenth the cost of previous designs. After our initial test and evaluation, we were pleasantly surprised by DepthQ’s performance and decided to design the overall system with these projectors. Eventually, we plan to add a fourth wall and additional projector to this system.”

Dr. Carolina Cruz-Neira is the W. Hansen Hall and Mary Officer Hall/BORSF Endowed Super Chair in Telecommunications at the University of Louisiana at Lafayette and the Chief Scientist of the Louisiana Immersive Technologies Enterprise (LITE). A pioneer in the field of Virtual Reality and High Performance Computing, her accomplishments include the design of the CAVE™ Virtual Reality Environment, the CAVE™ Library software specifications and most recently the Open Source VR Juggler API.
