インパルス成分を有する振動刺激によるインタラクティブ触覚ディスプレイ Method of Tactile Presentation Using Impulse Component in the Vibration
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.
