1. A touch processing method for a graphical user interface, the method including the steps of: using a processing unit including at least one CPU or GPU to read a sensed data array from a touch panel, wherein said sensed data array is generated in the touch panel without going through a process for calculating touch coordinates; using said processing unit to perform a conversion procedure on a GUI to generate a GUI image, wherein said GUI image has a background area corresponding to a touch plane of said touch panel, and said background area contains a plurality of icons with each of said icons representing an object; and using said processing unit for performing a touch processing procedure, wherein said touch processing procedure uses said sensed data array to get touched position information or uses both said sensed data array and said icons of said GUI image to get touched icon information for locating or indicating at least one of said icons and activate the object function thereof.
