Quantification of Tactile Effect of Building Materials.

The object of this paper is to clarify the quantification of the tactile effect of building materials from the physical one.Sensation and perception were interpreted on the basis of psychology and physiology. The concept of psychophysio-dynamics was proposed connecting psychophysics with psychodynamics. It was found that the tactile effect of building materials can be pridicted from the physical values of warmth, hardness and roughness. The applicability was verified.
