Psychophysical Influence on Sense of Weight by Visual Superimposition of Moving Objects(<Special Issue>Mixed Reality)

Abstract

When humans sense the weight of real objects, their perception is known to be influenced by not only tactile information but also 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 (MR visual stimulation). In this paper, we studied the psychophysical influence on the sense of weight by using a real object that has a CGI superimposed on it. In the experiments, we show CGI representing the inertial force caused by the objects placed inside, while the subject swings the real object. The results of the experiments show that the subjects sensed weight differently when being shown the CGI animation.
