Electronic device and method for controlling zooming of displayed object
First 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, andwherein the reference line is a bottom edge line of the touch screen.

Abstract
An electronic device and a method for controlling zooming of a displayed object are disclosed. The method includes: receiving a single-point slide operation performed by a user on a displayed object of a touch screen, and generating a slide signal; parsing the slide signal to obtain a slide track and a feature value of the single-point slide operation; determining whether the feature value of at least one point in the single-point slide operation is greater than a preset value; and when the feature value is greater than the preset value, controlling zooming of the displayed object according to the slide track. A slide track and a feature value of a single-point slide operation of a user are identified, and when it is determined that the feature value is greater than a preset value, zooming of a displayed object of the touch screen is controlled.

4. An electronic device, comprising:
-
a touch screen; one or more processors; a memory coupled to the one or more processors; and one or more programs being stored in the memory and configured to be executed by the one or more processors, wherein the one or more programs includes instructions for; receiving a single-point slide operation on an 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 line 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. - View Dependent Claims (5, 6)
