摘要

Research shows that virtual reality (VR) is beneficial for training purposes and fidelity is positively correlated with increased performance across a number of tasks, however, much of this research focuses on system fidelity. Some studies, which also incorporate visual complexity, show complexity reduction leads to better task performance. Psychology research suggests altering fidelity could play a role in more efficient representations to facilitate encoding, yet this has not been empirically proven for virtual training.;The goal of this thesis is to provide a greater understanding of visual elements and how their presentation influences task performance. We outline a comprehensive deconstruction of visual complexity for training through the use of fidelity-altered context techniques called FACTs, which rely on fidelity contrasts to focus the user's attention and to improve training transfer. We include a study to discover the effectiveness of these techniques through an error identification task using the LEGO brick system. Although we found no significant main effects, subjective results show a preference for FACTs over traditional VR techniques. Variances in the data imply that the current protocol allows for too many degrees of freedom leading us to reject conclusions drawn from our current approach. Therefore, we consider ways to further refine the study protocol and FACTs in order to find conclusive results for future research.
