 note = {The purpose of this study was to investigate the ability of the human tactile sense to discriminate fine step-heights depending on surface motion. In the previous paper, we reported the development of a device which enabled to present a fine step-height ranging 0-30 μm while moving at a velocity ranging 0-60 mm/s. This device was applied to investigate the human tactile sensation capability for moving fine step-heights. Six human subjects touched various step-heights moving at two velocities of 20 and 40 mm/s, and judged which step-height was higher. As a result of the psychophysical tests, the subjective equalities and the difference thresholds for discriminating the moving step-heights were determined. The experimental results proved that the difference thresholds and the subjective equalities resulting from a step-height velocity of 40 mm/s are larger than those from 20 mm/s. This reveals that the velocity of the step-height affects the discrimination capacity, and that the resolution and the accuracy are decreased with the increasing velocity of the step-height.},
