A method of operating a touch control electronic device includes the steps of: (a) activating a program; (b) detecting a touch signal forming a curve, which includes a first sensing point and a second sensing point; and (c) calculating a distance variation between the first sensing point and the second sensing point with a reference point so as to change an attribute value of the program, wherein the reference point is set according to the curve.
