Outline of Final Research Achievements

The purpose in this study was to identify factors for the material perception from motion and to illustrate the perceptual law of material perception. The kinetic subjective contour was used that the vertical boundaries oscillated around the center of the inducers. It was examined whether amplitude and frequency changes in an inducer’s oscillation influence the visual impressions of an illusory surface’s hardness and viscosity. The results indicated that hardness and viscosity impressions varied in accordance with the amplitude and frequency change in inducers’ pendular motion. These facts provide evidence of the partial relationship between material impressions such as hardness and viscosity related to amplitude and frequency changes in pendular motion. These findings indicate the possibility that material perception derived from motion is explicable in relation to physical motion based on the physical property of a material and force related to motion.
