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 o f sense which the human finger has, we consider to stimulate the tacti le sense by vibration and to develop a tactile feedback system. The pr oposed vibrotactile stimulator employs a number of vibrating pins to p rovide 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 vi bro-tactile stimulation. Next we arrayed the micro resonators in a mat rix state and constructed the tactile display. We performed the tactil e feedback experiment using this display. From these results, we descr ibe a suitable way to present vibro-tactile stimulation.
