This study was using virtual reality technology to build a ”virtual wheel-type vehicle operation training system”, to evaluate the 3D virtual reality in the military education of adaptability. Consider Lombard and Ditton (1997) proposed the concept of ”presence” as a crucial factor to evaluate virtual environment. Stanney (2002, 2003) and Thalmann (1994a, 1994b) both also thought that if virtual reality can induce presence more, the corresponding evaluation is higher. Therefore, this study was to measure the subjective and objective way to understand the ”presence”, as students can adapt to the degree of understanding of virtual reality. In physical measurements, more based on complexity” theory to analyze, to understand their adaptive capacity.
