In this paper, we report a method for evaluating the roughness of floors from a viewpoint of the graze caused by an accidental touch with the floor and the pain caused by contact with the floor. The outline of this study is as follows. First, we made a psychological scale from a viewpoint to cause the graze and pain by contact with the floor, using the sensory test. Next, we investigated how to measure the physical quantity of the roughness of floors corresponding to the psychological scale and obtained the physical quantity corresponding to the psychological scale. As the result, we presented the evaluating index determined from the relation between psychological scale and physical quantity, as a method for evaluating the roughness of floors from a viewpoint of the graze and pain caused by contact with the floor.
