<p>A magnetic touch system is provided to implement a sensitive touch function with only the minimum current without physical contact by implementing a conductor with a touch sensor and detecting touch change according to distortion of a magnetic field formed around the conductor. A PSU(Power Supply Unit)(100) generates certain current by being turned on simultaneously together with initialization of a touch system. A magnetic touch sensor(102) is formed on a substrate and forms magnetic field by receiving the current from the PSU. A controller(104) determines the touch by detecting a magnetic field change of the magnetic touch sensor if an object approaches the magnetic touch sensor, and transmits execution data by detecting coordinates of the substrate when the touch is inputted. An execution interface(108) interfaces an execution operation of the touch system by the execution data received from the controller. A coordinate database(106) stores x-y coordinate data on the substrate and is selectively read by the controller.</p> |
