We discovered the “R-V Dynamics Illusion,” a psychophysical phenomenon caused by the difference between the dynamics of real object (R) and virtual object (V) in mixed reality (MR) space. Previously, we confirmed that the real object is lightly perceived by a MR visual stimulation with a movable portion. In this paper, as a next step, we experiment to measure how much lighter the real mass will be perceived by the MR visual stimulation. In addition, further experiments will be conducted to change the mass of the real object as well as changing the liquid capacity of the CG to see the change in weight perception caused by R-V Dynamics Illusion.
