Distributed Interactive Simulation for Group-distance Exercises on the Web

In distributed-interactive simulation (DIS), simulators act as elements of a bigger distributed simulation. A groupdistance exercise (GDE) based on the DIS approach can therefore enable group training for group members participating from different locations. Our GDE approach, unlike full-scale DIS systems, uses affordable simulators designed for standard hardware available in homes and offices. ERCIS (group distance exERCISe) is a prototype GDE system that we have implemented. It takes advantage of Internet and Java to provide distributed simulation at a fraction of the cost of full-scale DIS systems. ERCIS illustrates that distributed simulation can bring advanced training to office and home computers in the form of GDE systems. The focus of this paper is to discuss the possibilities and the problems of GDE and of web-based distributed simulation as a means to provide GDE.
