Abstract

Immersive Virtual Reality (IVR) simulator training is an interactive form of computer-based training that can positively promote the transfer of skills from training to trainees. Even at a lower physical fidelity IVR simulators may more effectively train individuals on the operation of virtual heavy equipment compared to written, demonstrative, and oral computer-based training. IVR simulator training may also be beneficial for implementation of heavy equipment operation training as a means to promote familiarization of controls and foster self-efficacy and confidence in trainees. A multi-stage IVR simulator was created for this study that both trained participants on wheel loader operations and measured participant’s performance in filling a dump truck. The IVR simulator was built to incorporate video game industry best practices and was optimized for simulator performance and reduced simulator sickness. Participants were assigned to control or treatment groups and matched based on their age, the number of hours they played video games, and the hours of experience they had with operating heavy equipment. Results showed a significant reduction in collisions in the operation of virtual heavy equipment by 40% among users that received IVR training. Although not statistically significant, analyses also showed an average 21% reduction in wasted material and 13% reduction in operation time needed between control and treatment groups. Furthermore, the IVR training method had an average 27% reduction in bucket fills needed and 20% less time needed to complete the operation, which was a 9% and 5% greater improvement that the control group’s training method. These findings show merit for using IVR simulators as a rapid training tool for creating confident operators under safe and cost-effective training settings. Additional research into increased physical fidelity research is warranted to validate and investigate the results found in this study.
