在龙门起重机操作员的支持下，他们在船舶和拖车之间装卸集装箱，我们可视化了初学者和经验丰富的操作员之间的视线差距。目的是探索技能转移的培训方法。通过对眼动数据的分析，发现50 m以上的工作环境对初学者心理上具有压迫性，初学者对物体重要部位的注视不平衡。另一方面，经验丰富的操作员通过扩大视线范围来努力收集信息。在训练时，在紧张的环境中，过多的输入反而会导致初学者的恐慌。逐步扩大投入的范围变得重要。此外，初学者还需要认真模仿有经验的操作人员对物体的聚焦，这样才能真正掌握技巧。
With the support of gantry crane operators who load and unload containers between vessels and trailers, we visualized the gap in the line of sight between beginners and experienced operators. The aim was to explore training methods for skills transfer. Through an analysis of eye-movement data, we found that the working environment at 50 m above ground level was psychologically oppressive, so the beginners had an imbalanced gaze to the vital parts of the object. On the other hand, experienced operators made efforts to collect information by widening their gaze range.When it comes to training, in a stressful environment, too much input may instead lead to panic for beginners. Gradually expanding the scope of the inputs becomes important. In addition, beginners also need to carefully imitate the experienced operators in focusing on objects, so that they may truly grasp the skills.
