N2 - This paper reports creation of virtual surface textures using a MEMS tactile display. The display consists of large-displacement MEMS actuators with hydraulic amplification mechanisms. By controlling the displacement, the vibration frequency, and actuator driving patterns, the display could generate tactile feeling of various surface textures to a fingertip. In order to investigate the produced virtual tactile sensation quantifically, we prepared 18 samples, such as wood, urethane foam, and sandpapers, to compare. The subjects were requested to select one of these samples that had a texture most similar to the one produced by the display. We categorized the samples with respect to roughness, softness, surface energy and warmness, and correlated the control parameters to the selected samples. We also used information amount to analyze the results with respect to shareness among the subjects. We experimentally found that displacement of actuators had strong correlation with the roughness and the display presented hard surfaces except when apparent motion was generated.
