TACTILE FEEDBACK CONTROLLER, METHOD OF CONTROLLING THE FEEDBACK CONTROLLER, AND METHOD OF TRANSMITTING MESSAGE USING TACTILE FEEDBACK CONTROLLER

摘要

A tactile feedback controller (100) controlling controlled devices, comprising a base (110), a cap (120), a piezoelectric motor (130), a rotation control device, and a rotating state detection device. Since the tactile feedback controller (100) uses the piezoelectric motor (130) capable of providing a large torque even in a low speed rotation, a sufficiently large tactile feedback can be provided to the cap (120) even when the cap (120) is rotating at a low speed. Also, since the base (110) and the cap (120) are fixed to the stator (140) and the rotor (150) of the piezoelectric motor (130), respectively, a backlash can be eliminated. As a result, since the expressive power on the tactile feedback is not lowered, the tactile feedback controller having a variety of expressive power on the tactile feedback can be provided.
