VR is a natural outgrowth of several enabling technologies: workstations, computer graphics, visualization, displays, interactive devices, and software. The user can then directly manipulate simulated objects and leave behind the limitations of the physical world. The goal of this project was to examine VR for potential application in command, control, battle management, and situation awareness. Work focused on establishing and developing an optimized hardware and software architecture for a variety of applications. The purpose of this report is to provide a technical summary of MITRE's findings. The report begins with a user-interface device description and evaluation and a description of the software requirements for integrating these devices in a VR platform and the implications on the software architecture. The report then describes the Virtual Environment Architecture (VEA), the software architecture used to develop a real-time stand-alone interactive VR platform, including rationale, tradeoffs, performance issues, and use of a knowledge-base. Finally, the report describes a scenario developed for demonstrating the utility of the VR platform in a battle management prototype application.
