Previously, ON/OFF switching control has been used to drive an active type surface acoustic wave tactile display. Friction between a slider and a stator transducer is varied to higher or lower value, binarized values, according to the switching. The control, however, produced tactile sensation has few varieties due to the binarization. In this study, amplitude modulation is proposed to control the friction to be set at any value. Such control can produce many kinds of the tactile sensation. A controller is fabricated to realize the modulation driving. Additionally, a 3-dimentional surface profile scanner is built up to reproduce tactile sensation during rubbing a remote solid surface. The scanned profile is translated to control signals to be downloaded to the controller. The newly developed system is experienced by some subjects.
