Outline of Final Research Achievements

This goal may be achieved with a virtual reality view for a region of interest from an arbitrary viewpoint. An endoscopic pseudo-viewpoint alternation system for this purpose was developed and tested.
Rendering error of the needle was problematic, as surgeons perceive needle direction from needle shape. So we developed rendering error on the needles, implementing the current needle and the forceps on the same plane as rubber sheet. And, Suturing performance improved with the new virtual reality endoscopic display system. Viewpoint alternation resulted in an overview that improved depth perception and allowed subjects to better aim the marker. This suggests the proposed method offers users better visualization and control in endoscopic surgery.
