Abstract:

Virtual Reality (VR) has emerged as a promising training tool across various domains due to its immersive and cost-effective nature. However, its effectiveness is influenced by factors such as technical limitations, adverse side effects, and individual differences. This study explores the effectiveness of VR-based parachute descent training, focusing on the impact of Field of Regard (FOR) on task performance, drop-seat accuracy, course correction, and trainee confidence. Thirty-five participants engaged in VR parachute descent training sessions using an HTC Vive Pro headset. The analysis employed Bayesian methods to evaluate the effects of FOR variations on the key performance indicators. Results from Bayesian analyses suggest that FOR variations did not significantly affect task performance, drop-seat accuracy, course correction, confidence levels, time to first fixation, dwell time, total number of fixations, or time spent searching. Specifically, the posterior distributions for differences between groups with varying FORs showed a high probability of being close to zero for all measured variables, indicating no substantial impact of FOR on these aspects of VR training performance. These findings challenge the assumption that larger FOR enhances VR training effectiveness. It suggests that other factors, such as content quality, instructional design, and individual differences, may play more critical roles in determining the success of VR-based training programs. Overall, these findings provide valuable insights into the optimal design of VR training environments, suggesting that larger FOR may not always result in improved training outcomes. Additionally, considerations for training implications and cost-effectiveness are discussed, emphasizing the importance of evaluating technology before adoption to ensure desired training outcomes are maintained while minimizing unnecessary expenses. This research contributes to the understanding of VR training effectiveness and informs future developments in VR-based training methodologies.
