generating, according to the contact parameter and the contact position, a corresponding operation instruction; and
executing, according to the operation instruction, a corresponding operation;
wherein the step of generating, according to the contact parameter and the contact position, a corresponding operation instruction comprises:
determining an input control from a plurality of input controls according to coordinates of the contact position, wherein each input control corresponds to two or more input characters;
acquiring a preset pressure threshold and a preset contact area threshold corresponding to the determined input control; and
generating, according to the contact parameter and the preset pressure threshold as well as the preset contact area threshold, an operation instruction instructing the input control to display the corresponding characters;
wherein the step of generating, according to the contact parameter and the preset pressure threshold as well as the preset contact area threshold, an operation instruction instructing the input control to display the corresponding input characters comprises:
generating, when the pressure value exerted on the touch screen by the object is smaller than a pressure threshold and the contact area is smaller than a contact area threshold, a first instruction, the first instruction being used to instruct the input control to display a first input character;
generating, when the pressure value exerted on the touch screen by the object is smaller than a pressure threshold and the contact area is greater than or equal to a contact area threshold, a second instruction, the second instruction being used to instruct the input control to display a second input character;
