Presenting a Sense of Self-motion by Transforming the Rendering Area Based on the Movement of the User’s Viewpoint

Abstract

Computer graphics is a core technology that can produce realistic images. However, it is difficult to provide sense of movement and immersion using only visual images. In this study, we propose to enhance the sense of self-motion by deforming the rendering area according to the vection illusion which induces a sense of immersion only with images. In general, the body is slouched backward while accelerating forward, and the field of view becomes relatively wide. Therefore, enlarging the drawing area should have a similar effect when the user’s viewpoint in the VR accelerates forward. If the user moves backward, the drawing area should be reduced.

We constructed a driving simulation environment to demonstrate the proposed method. The deformation of the drawing area caused VR motion sickness because the expected and the actual deformation differed. It was also confirmed that the transfer of the rendering area enhances the sense of immersion.
