Mixed Reality Training of Military Tasks: Comparison of Two Approaches Through Reactions from Subject Matter Experts

This paper discusses a training-based comparison of two mixed reality military trainers utilizing simulation elements that are categorized on different areas of the virtuality continuum. The comparison encompassed exposing subject matter experts (SMEs) to the training systems. Independent groups of SMEs interacted with each system through conducting expert system evaluations. Independent groups of military officers experienced each system for call for fire/close air support training. Following these exposures, participants were queried on the constructs of simulator sickness, training utility, simulator fidelity, usability, and immersion. The results are contrasted and discussed. The outcomes of this comparison serve to promote discussion among the scientific community concerning the training tradeoffs affected by the virtuality continuum.
