We have proposed and developed a vibratory tactile display system which enables the operator to recognize textures of the surface of a material in a virtual environment with somatosensory consistency. It displays the vibration generated to represent surface texture of a virtual object according to the movement of the operator's fingertip.<br>By focusing on impulses found in the recorded vibration, we propose a method of generating vibration in which frequency and power of the impulses are conserved.<br>We have found that the impulse component in the vibration is a significant factor in displaying tactile information. The proposed method proved to give the tactile sensation with a higher sensation of presence than methods in which neither phase information nor impulses are conserved. The validity of the proposed method was confirmed by psychophysical evaluation experiments.
