External device identification method and apparatus in a device including a touch spot, and computer-readable recording mediums having recorded thereon programs for executing the external device identification method in a device including a touch spot
An external device identification method in a device including a touch spot, an apparatus, and a recording medium are provided. The external device identification method includes generating a first micro-current signal that is induced when the touch spot is touched by a human being and includes device information about the device including the touch spot, propagating the first micro-current signal to an external device via a human being, receiving a second micro-current signal including device information about the external device from the external device via the human being, detecting the device information about the external device from the second micro-current signal, identifying the external device by using the device information about the external device, and connecting the device including the touch spot to the external device through a communication channel.
