Comparison Results of Virtual 3-d Devices for Product Design Reviews

The purpose of this study was to provide insights into how virtual 3-D visual display systems contributed to cross-functional team collaboration in a product conceptual design review environment. During this empirical testing, three commercially available 3-D display systems [Helmet Mounted Display (HMD), Binocular Ommi-Orientation Monitor (BOOM), and stereoscopic shutter glasses with monitor] were compared to a traditional monoscopic (2-D) monitor system. The design task was to evaluate a new concept for armored vehicle refueling. Test results and analysis indicated that some virtual environment (VE) technologies provided significant advantages during certain phases of the review process, but no single device fully satisfied all individual and team needs. The primary conclusion reached was that while VE technologies have a potential to reduce product development time and life cycle costs, a phased approach using VE devices supported by face-to-face team member interaction is recommended.
