Experimental case study demonstrates improved assembly completion time and reduced mental fatigue during precision equipment co-assembly, suggesting enhanced micro-operation workflows.
Recent research indicates that inappropriate visual coding exacerbates the side effects of cognitive load imbalance in the recognition of graphical symbols on VR/MR interfaces, leading to severe issues in individuals' understanding of task processes. In response to this situation, a VR/MR interface strategy supporting precision equipment collaborative assembly is proposed. This strategy revolves around interactive cues such as virtual-real scene registration tracking, spatiotemporal data synchronization, eye gaze, and motion capture, aiming to construct a visual coding design mechanism for VR/MR interfaces. The goal is to enhance the quality of assembly intent expression and slow down the accumulation rate of individual mental fatigue. This study designs an experimental VR/MR interface coding prototype system. Through case study experiments, direct evidence is found that the proposed MR interface coding strategy has advantages in assembly completion time, decision-making ability, visual perception experience, and operational interaction experience. The experimental results of this study will be beneficial for guiding the assessment of VR/MR manual micro-operation quality processes, especially in the field of precision assembly.
