The visual-auditory interaction feedback can significantly influence the interactive experience of learners, highlighting the importance of using appropriate visual-auditory interaction techniques to improve the quality of virtual reality training. To investigate the effect of visual-auditory interaction feedback on learners in VR safety training, this study proposes a visual-auditory feedback interaction design method tailored for VR power safety training and validates its effectiveness through behavioral experiments. The method involves selecting representative power safety training scenarios and inviting suitable volunteers to test the feedback effects of different visual-auditory interaction approaches. The study focuses on assessing the impact of learning difficulty, learning satisfaction, and cognitive load in the training, aiming to identify the optimal visual-auditory interaction feedback combination. The results indicate that all four visual-auditory interaction feedback methods used in the experiment have significant effects (p<0.05). Notably, the combination of text and speech significantly enhances learners’ satisfaction, while simultaneously reducing learning difficulty and cognitive load to the lowest levels. This research offers valuable insights and guidance for the development of interactive feedback mechanisms in virtual reality safety training. Moreover, the findings have direct implications for enhancing interactive design applications in virtual reality safety training environments.
