A hybrid tactile displaying method of realistic texture is realized by use of ultrasonic vibrator and force display. Various realistic tactile senses are displayed by controlling multiple factors including roughness, softness and friction sense. First, a tactile displaying system was constructed for displaying roughness, softness and friction sense, simultaneously, by compensating the interference among multiple parameters of ultrasonic vibration and force feedback on multiple tactile senses. Second, the proposed method for displaying softness and friction sense were verified by several sensory evaluation experiments. The relationship between each control parameter and the tactile senses were quantified as well. Then, material discrimination experiment was conducted. As a result, percentage of questions answered correctly was more than 87.5 in all materials. Finally, the tactile senses of real materials and hybrid artificial tactile senses were evaluated using adjectives. As a result, it was verified that the correlation coefficients between real materials and hybrid artificial tactile senses were quite large in the evaluation items on roughness, softness and friction sense.
