A touch sensor for detecting three-dimensional features of an object includes a rubber skin and a plurality of pins provided on one surface of the rubber skin. The rubber skin and pins are formed of materials having different colors to facilitate image processing. An image acquisition device is provided facing the one surface with the pins. When an object presses against the outer surface of the rubber skin, the rubber skin is depressed in a way that corresponds to the shape of the object. This spreads the pins, forming a pattern of a different brightness that is detected by the image acquisition device to thereby enable three-dimensional features of the object to be identified.
