APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA USING EARPHONE

摘要

According to an embodiment of the present specification, a method for controlling a portable device connected to an earphone having a coil comprises the steps of: detecting whether one of left and right units of the earphone is spaced apart from the ears of a user; generating an electromagnetic pattern corresponding to an ID of the portable device at the spaced unit by using a controller; and receiving data transmitted from an external device in correspondence with the ID of the portable device by using a communication unit. Furthermore, according to an embodiment of the present specification, a method for controlling a display device comprises the steps of: displaying a graphic user interface by using a display unit; sensing an earphone approaching the display unit by using a sensor unit; sensing an electromagnetic pattern of the earphone approaching the display unit by using an electromagnetic pattern sensing unit; acquiring an ID of an external device connected to the earphone from the sensed electromagnetic pattern by using a controller; and transmitting data to the external device identified by the acquired ID of the external device by using a communication unit.
