ELECTRONIC DEVICE CAPABLE OF CONTROLLING AN OPERATION USING A NON-CONTACT SENSOR AND A CONTROL METHOD THEREOF, CAPABLE OF CONVENIENTLY CONTROLLING VARIOUS OPERATIONS BY THE NON-CONTACT SENSOR

摘要

PURPOSE: An electronic device capable of controlling an operation using a non-contact sensor and a control method thereof are provided to display an operation control menu and a pointer on a screen without touching a screen, thereby executing a desired operation.;CONSTITUTION: A controller displays an image on a display unit(S200). If an adjacent object is sensed by a sensing signal of a sensor, the controller displays an operation control menu and a pointer on one area of the display unit(S205,S210). The sensor senses the adjacent object by an ultrasonic reflected wave. If movement of the adjacent object is sensed by a change of the sensing signal, the controller moves a display location of the pointer corresponding to movement of the adjacent object(S215,S220).;COPYRIGHT KIPO 2011
