The virtual surgery is one of technically difficult applications. With the expansion of the increasingly fine and complicated ear microsurgery, new methods are required to train the doctors. It is necessary and of practical significance to apply VR to the ear micro-operation, which is a functional operation with high precision and great difficulties. In this article, medical VR applications were reviewed. The application of VR to the ear microsurgery was discussed and the virtual ear microsurgery system was designed.展开更多

But, in the reality world, we can see some kind force of an existence does not come from outside. For instance, when a person takes the action such as speaking, movement of arms, we cannot see any force loaded from outside of this person. Then, here is the question： Where does this kind of force come from？ This paper is to demonstrate to prove that there is the second source of force, which comes from internal of a kind of object.展开更多
