观察和操作的间接方法损害了腹腔镜外科医生的手眼协调。手眼协调受到两种影响：相机图像的错误定位和仪器运动的错误方向。错位是由于外科医生期待监视器而不是放在他/她的手上。方向错误是由内窥镜的视线和外科医生直视腹部时的自然视线之间的差异引起的。因此，显示器上的仪器移动方向与预期方向不同。这些影响非常令人困惑，需要长时间的密集训练才能克服。本文概述了实验和辅助手段，以减少错位和定向误差的影响。Storz的ViewSite是目前最简单的解决方案;它将屏幕重新定位在外科医生的手上方。在德尔夫特理工大学，正在进行关于补偿错误取向的研究。该研究的成果是摄像机旋转方法和新型可操纵内窥镜Endo-Periscope。
The indirect method of observing and manipulating impairs the eye-hand coordination of a laparoscopic surgeon. Eye-hand coordination is impaired by two effects: a mislocation of the camera picture and a misorientation of the instrument movements. The mislocation is due to the fact that the surgeon is looking forward to a monitor and not down on his/her hands. The misorientation is caused by a difference between the endoscope's line-of-sight and the surgeon's natural line-of-sight when looking directly into the abdomen. As a result, the instruments on the monitor move in a different direction from that expected. The effects are very confusing, and require a long and intensive training period to overcome. This paper gives an overview of experiments and supporting aids to reduce the effects of mislocation and misorientation. Storz' ViewSite is currently the most simple solution; it relocates the screen above the surgeon's hands. At the Delft University of Technology, research is being carried out on compensation for misorientations. Outcomes of the research are a camera rotation method and a new type of steerable endoscope, the Endo-Periscope.
