Using VRML and Collaboration Tools to Enhance Feedback and Analysis of Distributed Interactive Simulation (DIS) Exercises

Overview

Military training exercises using Distributed Interactive Simulation (DIS) are often recorded and played back so trainees can visualize the 3D exercise and receive feedback in the form of an After Action Review (AAR). This paper discusses the capability of converting DIS exercises into virtual worlds accessible over the Internet using the Virtual Reality Modeling Language (VRML). The Internet accessibility of VRML, combined with other network-based collaboration tools supports the implementation of a "Remote expert" where geographically dispersed teams of trainers can provide feedback to trainees in other locations. The VRML exercise file can be annotated with multi-media collaboration input and analytical information.
