R-V Dynamics Illusion: Psychophysical Influence on Sense of Weight by Difference Between Dynamics of Real Object and Virtual Object

Abstract

In Mixed-Reality space, it appeared that the sense of weight can be affected by a MR visual stimulation with a movable portion. We named this psychophysical influence caused by the difference between dynamics of the real object (R) and the virtual object (V) movement, the “R-V Dynamics Illusion”. There are many combinations of experiments that can be conducted. Previously, we conducted experiments of the case where the real object is rigid and the virtual object is dynamically changeable. In this paper, we conducted experiments of the case where the real object is liquid and both the real and the virtual objects are dynamically changeable. The results of the experiments showed that the subjects sensed weight differently when virtual object with a movable portion is superimposed onto a real liquid object.
