Abstract
Patterns displayed on a touch screen are swapped in response to occurrence or movements of touch points on the touch screen. Therefore, when a user of the multi-touch device including the touch screen intends to swap patterns displayed on the touch screen, he or she is merely required to give a few simultaneous touches corresponding to the patterns on the touch screen or to simply move the patterns on the touch screen using simultaneous touches.
