An Evaluation Method of Depth Perception on Stereoscopic Display

We proposed an improved evaluation method of depth accuracy in the virtual world, and discuss a result of this evaluation. In this evaluation, we focused the disorder of the convergence and the accommodation, and used a subjective assessment method applying moving stimulus images and quantitatively observed effects involving the disorder of the convergence and the accommodation. This method was based on the evaluation method of the depth accuracy of real space. In this method, we used three objects in the virtual world, and compared these position relationships. The main index of the evaluation was the distance between static objects and the dynamic object. A result of the evaluation suggests that the size of appearance was most important factor. However, it seemed also that this disorder lead to an inaccurate perception of depth.
