Abstract
The form to feel the softness was considered that there are features called " rounded ", " feel the force of gravity ." As a result of experiment with white samples with each feature, rounded form is felt higher softness, but it became clear that spherical object is not the case. In addition, the form that is too collapsed looked like a rather hard look or liquid. In the experiments with transparent samples and semi-transparent samples, there is not big difference to feel the softness. However, it is suggested that even with the same shape, type of softness is different.
