We have developed a set of analytic tools to identify and develop virtual environment (VE) simulation training applications. Task selection criteria help identify tasks that might benefit from VE training; VE requirements matrices are used to derive VE training system requirements; and cost-effectiveness factors are used to judge the relative merits of VE(More)
