Performance measures for training spatial knowledge in virtual environments using Division Inc. and VEGA Marine geometric models

Spatial knowledge, often used in military operations, is a significant component of military skills. It includes knowledge of the relationships of one object to others, the movement of objects relative to others, and the relationship of the human to each of the objects, and this involves perception and awareness of the human's position within the situation. Key ingredients include both time and distance perceptions by the humans. Recently, the military have been exploring the use of virtual environment technology; the focus for training systems has been on simulation of the environment and on the behavior of the objects from a mathematical modeling perspective. This paper examines two of the major factors involved in performance metrics for use within virtual environments. The focus of this research is on the performance measurement of the training environment using US Naval case studies implementing geometric modeling.
