Abstract
A method for analyzing a two-dimensional track to generate at least one non-linear index and a touch control module using the same are provided. The method includes: extracting a two-dimensional track; generating a plurality of displacement units in sequence according to the two-dimensional track, in which each displacement unit includes a displacement amount and a displacement direction of the two-dimensional track moving in a preset time interval; comparing the displacement amount of each displacement unit with a reference value in sequence; calculating an included angle formed between the displacement direction of the displacement unit and a displacement direction of a previous displacement unit, when the displacement amount of the displacement unit is greater than the reference value; accumulating the included angles in sequence to obtain an accumulated angle, in which the accumulated angle includes an accumulated value and a positive or negative sign; and converting the accumulated angle to at least one non-linear index.
