Abstract

Virtual environment has become one of the major factors in the training area. Flight simulation used by the military (US Naval Education and Training Command) has been known as beneficially helps to train the student pilots in much safer condition and lower expenses. The skills gained from this training should be transferable effectively into the real world tasks that the simulator simulates. It is believed that realistic simulation will contribute more to the learning process. However, it is unclear on what does the effect of realistic environments has on human perception, as there.is little evidence to support this assumption. Based on this reason, more researches have been carried out to determine how human environment perception functions with regard to memory and information retention in the virtual environment. Mania(2001) and Wooldridge(2003) suggested a simulation fidelity metrics, which is based on human judgements of memory awareness states. The metric focused on how a task is achieved rather than what is achieved by requiring the participants to report on how they recalled the information after VE exposure through selecting one of the four awareness states. The other learning factor that had been given an attention is the existence of schema usage in virtual reality. The work ofRobinson(2002), which is based on the experiment done by Brewer and Treyens(l981) suggested that schema or pre-existing knowledge did apply in the virtual reality as in real world. Based on the previous studies, this dissertation is set out to explore the effects of rendering quality on human cognitive strategies in VE focusing on both factors; the memory awareness states and the schema activation. The study is done by using two different scenes, flat shaded rendered as the low quality and radiosity rendered as the high quality scenes. Meanwhile, the experiment is carried out using a different way of reporting techniques, which was done by participants. The participants need to do an arrangement task in the real room instead of answering questionnaire. The study revealed ititeresting distribution of participant's responses in memory awareness states and the level of schema application, which suggested that the quality of the scene did play a role in different part of human memory.
