Micro resonator for a tactile display

This paper proposes a tactile display for presenting the moving or the strain direction to the skin of the human finger. Of the many types of sense which the human finger has, we consider to stimulate the tactile sense by vibration and to develop a tactile feedback system. The proposed vibro-tactile stimulator employs a number of vibrating pins to provide a ticking sensation to the human operator's skin. We use micro resonators which are driven by electromagnetic force to the vibrating pins. We performed an experiment to present vibro-tactile stimulation using a single micro resonator and confirmed the ability to perform vibro-tactile stimulation. Next we arrayed the micro resonators in a matrix state and constructed the tactile display. We performed the tactile feedback experiment using this display. From these results, we describe a suitable way to present vibro-tactile stimulation.
