Directionality of human tactile sensation capability in discriminating fine step-heights

In this paper, the authors conducted psychophysical tests to investigate the effect of the directionality of human tactile sensation capability in discriminating fine step-heights. We evaluated the capability of human finger to discriminate the step-heights of 0 to 20 µm moving at the angle of 0°, 45° and 90°. The results suggest that the different directions of touching motion affect the human tactile sensation for recognizing step-heights.
