Abstract

The object deformation is an essential information in the human recognition of the object softness. A system has been developed to control the fingertip contact area dynamically based on the detected contact force. The relative softness cognitive rate of four levels softness was 97 percent in the experiment with five adult volunteers. The absolute softness cognitive rate, the rate of correct answer while the displayed softness was compared to the real objects, was 78 percent. That was demonstrated experimentally the display of the object softness is possible by the dynamic control of the contact area at fingertip.
