Precise perception of virtual object position in real world
Precise perception of virtual object position in real world
摘要
Abstract
There is a deviation between actual and theoretical perceived positions of virtual object in stereoscopic display. Therefore, methods for precise position perception in real world are proposed in this paper. The causes for the deviation are analyzed on the basis of geometrical optics. Then deviation corrections are performed by error compensation with mathematic method and by remodeling virtual viewpoint dynamically with the movement of physical viewpoint. Experimental results show that these methods can reduce the position deviation to less than 10 millimeter, meeting the requirements for direct manipulation in multi-sensory virtual environment.关键词
