A washing machine and a method for controlling the same are provided. A haptic feedback interface device is in communication with a host computer and includes a sensor device that detects the manipulation of the interface device by the user and an electroactive polymer actuator responsive to input signals and operative to output a force to the user caused by motion of the actuator. Since the auxiliary capacitor can be formed by using a thin insulating film, it can have a large capacitance. Use of an extra fabrication mask for thick oxide transistors is avoided by using only thin oxide transistors.
