HAPTIC FEEDBACK DEVICE AND METHOD FOR CONTROLLING THEREOF

摘要

PURPOSE: A haptic feedback device is provided to successively change driving voltage about an actuator by a control unit. CONSTITUTION: A haptic feedback device(100) includes a haptic device(110), an actuator(120), and a control unit. A contact pressure is applied to the haptic device. According to a contact signal, the actuator generates the vibration. To successively change a driving voltage abut the actuator, control unit applies the driving voltage.
