背景：这项研究用一种模拟内窥镜手术情景的设备来测试知觉-运动协调。方法：受试者接受了一种设备的训练，然后测试了另一种设备，其中改变了摄像机、外科医生或手术视野中的物体的位置。结果：结果表明，摄像机位置或外科医生位置的变化都会扰乱操作。然而，当摄像机和外科医生的位置一起改变时，熟练的操作能力保持不变。结论：这表明技能取决于虚拟手和眼睛之间的一致映射，而不是特定的视觉或运动方向。结果表明，手术过程中摄像机的移动可能会扰乱协调动作。此外，在训练模拟器的设计中，摄像机和仪器之间的映射可能比显示器的静态外观或运动的拓扑更重要。
Background: This study examined perceptual-motor coordination with an apparatus that simulated a situation representative of endoscopic surgery.Methods: Participants were trained with one arrangement of the apparatus, then tested with an alternative arrangement in which either the positions of the camera, the surgeon, or the objects in the surgical field were altered.Results: Results showed that changes of either the camera's position or the surgeon's position disrupted performance. However, when the camera and surgeon positions were changed together, skilled performance was maintained.Conclusions: This suggests that skill depends on a consistent mapping between the virtual hands and eyes, but not on the particular visual or motor orientations. The results suggest that movements of the camera during surgery can disrupt coordinated action. Also, in the design of training simulators, the mapping between camera and instruments may be more important than the static appearance of the displays or the topology of the movements.
