| Research Abstract |
We examined the difference between perceived object size by vision, that by haptic in oral cavity, and that by haptic of finger using psychophysical technique. The results of experiments suggested that object size which is haptically perceived in oral cavity tend to be overestimated than that visually perceived. In addition, we elucidate whether the magnitude of phase difference in oscillation influences the visual impressions of an object's elasticity which relate to food texture impression. The phase differences in the oscillating motion of inducers were controlled to investigate whether they influenced the visual impression of an illusory object's elasticity. The results demonstrated that the impression of the elasticity of an illusory surface with subjective contours was systematically flipped with the degree of phase difference.
