|1. (WO2015045060) ELECTRONIC DEVICE AND VERIFICATION METHOD FOR ELECTRONIC DEVICE|
|Title:||ELECTRONIC DEVICE AND VERIFICATION METHOD FOR ELECTRONIC DEVICE|
The purpose of the present invention is to provide an electronic device and a verification method for an electronic device, which provide a user with a distinct tactile sensation and thereby allow the user to easily enter necessary information. An electronic device according to the present invention comprises: a touch panel; a vibration device which causes vibration of the operating surface of the touch panel, said operating surface receiving manipulation input; a drive control unit which drives the vibration device by means of a drive signal to cause the operating surface to naturally vibrate at an ultrasonic frequency, wherein the drive control unit drives the vibration device in such a way that the natural vibration is switched between high and low levels in accordance with the distance traveled along the operating surface by the manipulating point of the manipulator; a first memory which stores first data representing a first password number that corresponds to switching the natural vibration between high and low levels a predetermined number of times; and a first verification unit which, when the operating surface has received manipulation input, verifies, against the first password number represented by the first data, the number of times the natural vibration has been switched between high and low levels by the drive control unit.
