Micro resonator using electromagnetic actuator for tactile display

Abstract

This paper proposes a tactile display for presenting the moving or the shearing direction to the skin of a human finger. We consider stimulating tactile sense by vibration and the development of 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 used micro resonators driven by electromagnetic force to 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 made a tactile feedback experiment using this display. From the experimental results, it was made clear that the tactile display had the ability to present much information to a human finger.
