Outline of Final Research Achievements

We present the concept of a novel haptic display device that could generate lateral localized displacement on a human fingertip, thus enhancing human perception of partial slip phenomenon. The proposed device is characterized by a bundle of pins whose ends gently make contact with a human fingertip. These pins are arranged on a supporting base that can displace endings of the pins to a different extent simultaneously with a single actuation, thus successfully generating localized slippage on a human fingertip. There are no relative movements between pins and the finger pad, resulting different skin stretch instead of moving across the skin surface. We proposed a dynamic model of interaction between haptic pins and finger for investigation of mechanical response of stress or strain on human fingertip under operation of the proposed haptic device. The results presented in this paper may help assess human slip perception for the development of haptic display devices.
