In Mixed-Realty (MR) space, the visual appearance (shape, texture, etc.) of a real object can be changed by superimposing a virtual object on it. Therefore, by creating systematic differences between visual and haptic perceptions using MR technology, we can analyze their influence on temperature perception. In our research group, we defined the changes in the visual information of a real object in MR space as “MR visual stimulation” and examine the influence of the haptic sense using MR visual stimulation. For our research, we focused on the temperature perception of the skin. In the first step, we verified the influence presenting MR visual stimulation has on the perceived position of the temperature perception. In the experiment, we presented MR visual stimulation and temperature stimulation in different positions. We confirmed the influence this difference has on the temperature perceived position. Our results demonstrate that temperature perception is strongly affected by visual stimulation.

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.
