In this research, we propose a producing method of softness sensation using a pinching type tactile device. The producing method of softness sensation which is significant information during the pinching motion by a human is proposed. The basically idea is apply a vibration to fingertip by the pinching type tactile device to increase receptor activity. A white noise and database which is made from experimental result in this paper, are used to generate the vibration. First, we conduct a basic experiment to decide the appropriate waveform of vibration. Finally, we conduct the evaluation experiment of softness perception. The subjective experimental result indicates that the proposed method can be used to produce softness sensation.
