    Abstract: A method for pattern file formation for driving and controlling the sensing element of an electric/electronic device and an apparatus for driving and controlling the sensing element of an electric/electronic device using the same, wherein an audio signal is called without playback to display, as a graph, a waveform of a visualized pattern file that has been generated without correction of the audio signal, so that a user can readily generate and correct the pattern file on a window screen; menus for preparing various pattern files are displayed; and it is made possible to apply a generated pattern file to the sensing element of an electric/electronic device using a variable voltage source, so that the light-emitting diode, vibration motor, actuator, and other sensing elements are driven and controlled either simultaneously or selectively, allowing the maximum sense of reality to be delivered to the user of the application program.
