Verification ofeffectiveness on skill learning usingone-to-manytactile transfer in surgical simulation

点击翻译按钮获取中文摘要

In this research, a laparoscopic surgery training system in which one trainer can teach plural trainees was constructed, and the effectiveness of skill learning was verified. The system is constructed from plural surgical VR simulators interconnected over a network. On this system, one teaching surgeon can show a model performance simultaneously toplural student’s simulators. Not only a visual performance, but also motion force of hands can be shown on a student’s simulator. So a student can trace the handling of the teacher’s forceps. An evaluation of effectiveness of this force guidance method on a surgical simulator was done.
