The purpose of this study is to clarify the dynamic factors that influence to the recognition of object's hardness by human fingers. In this study, objects ware pushed against the palmer right index finger, and we measured the change of evaluation of hardness by 7 steps and contact force when contact conditions change. Variation of contact conditions are as follows ; Sample's hardness (3 materials), Sample size (5mm, 10mm, 20mm diameter), Pushing depth (1mm, 2mm, 3mm) and Pushing speed( 1mm/s, 10mm/s, 100mm/s). From the results of this experiment, we suggest that when the speed of the depression becomes faster, even the contact force does not change, the mechano-receptor becomes more sensitive and that influenced the evaluation of object's hardness.
