Embodiment Construction

[0036] The present invention provides a method and system for unlocking the touch screen of a mobile terminal. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] Such as figure 1 A specific embodiment of a method for unlocking a touch screen of a mobile terminal is shown, wherein the method includes the following steps:

[0038] S100. Receive a user instruction to light up the screen and display a lock screen interface, detect that the user touches the touch screen, and acquire a sliding track of the user on the touch screen.

[0039] Before unlocking, a coordinate system is established with the top left corner of the touch screen as the origin, the top edge of the screen as the X axis, and the left...

Abstract

The invention discloses a touch screen unlocking method and system for a mobile terminal. The method includes the steps that (A) a user instruction is received, a screen lights, a screen locking interface is displayed, it is detected that a user touches a touch screen, and a sliding track of the user on the touch screen is obtained; (B) touch points which the sliding track covers are analyzed, and the area of each triangle composed of any three touch points is calculated by means of the analyzed touching points; (C) the largest area of the triangle is obtained to be compared with a preset threshold, and when the obtained area of the triangle is larger than the threshold, the touch screen is unlocked. The unlocking method is achieved by judging the area of the touching points, so that an unlocking interface is in full use, and the problem that precision of a sensor is lowered in the existing unlocking process due to the fact that an unlocking area is fixed is solved. Meanwhile, the user can automatically choose the sliding track in each sliding unlocking process of the mobile terminal, and operation is easy, convenient and quick to achieve.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a method and system for unlocking a touch screen of a mobile terminal. Background technique [0002] The more popular unlocking schemes for existing smartphones are basically slider unlocking or Jiugongge unlocking. Since the unlocking actions of the above unlocking schemes are the same every time, the user will lose interest in unlocking and reduce the user's product experience; and the existing Most of the unlocking schemes are basically operated in a fixed area of ​​the touch screen. After a long time, the touch screen in the unlocked area will be worn out, the accuracy of the sensor will be reduced, and eventually the service life of the entire touch screen will be shortened. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the object of the pr...
