[D89] R-V Dynamics Illusion in mixed reality space

When users sense the weight of real objects, their perception is known to be influenced by both of haptic and visual information. In a mixed reality (MR) environment, the appearance of touchable objects can be changed by superimposing a computer-generated image (CGI) onto them (We named this “MR visual stimulation”). In this demonstration, we show the psychophysical influence on the sense of weight by using a real object. Through the experiment, the subjects were required to swing the real object which contains a CGI of liquid. The inertial force which the subjects sensed was influenced by the viscosity, and they sensed the weight heavier in the case of high viscosity. When the movement states of a real object (R) and virtual object (V) differed, the dynamics of the virtual object influences on the sense of the weight of the real object, we named this psychophysical influence “R-V Dynamics Illusion.”
