The aim of this research is to develop a new approach and methodology for assessment of situation awareness (SA) in virtual environments (VEs). This paper presents an experiment to examine presence, task/user performance and SA with three different types of virtual environment (VE) display technology and gender. The interrelationship among SA, presence, performance, and sickness is also investigated. The results indicated there was no significant main effect of display type on SA or presence questionnaire, however, there was a significant main effect of display type on simulator sickness questionnaire under total scores (F = 3.72, df= 2(30), ρ< 0.035). There was also a significant correlation between VRSARM and performance (r = 0.39, ρ< 0.05), and sickness and recall (r = -0.377, ρ< 0.05). There were no significant correlation between presence and SA, sickness and performance, sickness and presence, as well as presence and performance. It was therefore concluded that presence does not lead to enhance SA and performance. Nevertheless, this experiment is used to generate design implications for future directions for SA in VE research in which associations between variables might be found.
