Claim:
1. A method for controlling zooming of an object displayed on a touch screen, comprising: receiving a single-point slide operation on the object when the object receives a touch by a single finger of a user; generating a slide signal in response to the single-point slide operation; parsing the slide signal to obtain a slide track, a starting point of the slide track, an end point of the slide track and a feature value of a touch point in the slide track; and zooming in on the object when a deflection angle is greater than or equal to 0 degrees and the feature value is greater than a preset value, wherein the deflection angle is a difference between a first angle and a second angle, wherein the first angle is an angle between a first line and a reference line, wherein the second angle is an angle between a second line and the reference line, wherein the first line is a connecting line between the end point of the slide track and a reference point, wherein the second line is a connecting between the starting point of the slide track and the reference point, wherein the reference point is an end point of the reference line, and wherein the reference line is a bottom edge line of the touch screen.
