Device identification method and apparatus, device information provision method and apparatus, and computer-readable recording mediums having recorded thereon programs for executing the device identification method and the device information provision method
First Claim
1. A device identification method for a touch screen device, the device identification method comprising:
- propagating a signal through a user body to an external device which is in contact with the user body, the signal being induced by the user body touching a touch screen surface of the touch screen device;
receiving, at the touch screen device, information related to the signal which is detected by the external device and an identification (ID) of the external device through a communication channel other than through the body of the user; and
identifying, at the touch screen device, the external device based on the received information related to the detected signal and the received ID of the external device;
wherein the signal is a micro-current signal including a scan frequency component.

Abstract
Provided are a touch-screen based device identification and information provision method and apparatus, and computer-readable recording mediums having recorded thereon programs for executing the touch-screen based device identification method and the information provision method. The device identification method for a touch screen device includes propagating a signal induced by touching a touch screen surface to an external device via the person, receiving information about the signal detected by the external device and an identification (ID) of the external device through a communication channel, and identifying the external device by using the received information about the detected signal and the received ID of the external device. Thus, the touch screen device and the external device can be connected to each other in real time by a simple and physical touch.
