A Perceptual Evaluation of the Ground Inclination with a Simple VR Walking Platform

Abstract

We evaluate how highly realistic the inclination of the ground can be perceived with our simple VR walking platform. Firstly we prepared seven maps with different ground inclinations of -30 to 30 degrees and every 10 degrees. Then we conducted a perception experiment of the inclination feeling with each of the treadmill and our proposed platform, and questionnaire evaluation about the presence, the fatigue, and the exhilaration. As a result, it was clarified that even if our proposed platform is used, not only the feeling of presence equivalent to that of the treadmill can be felt, but also the inclination of the ground up and down can be perceived.
