Embodiment 1
[0025] This embodiment provides a method for unlocking the touch screen, such as figure 1 As shown, the method includes:
[0026] 101. Determine whether there is at least one target track in the touch track.
[0027] Wherein, one endpoint of the at least one target trajectory coincides with the center of a preset closed area, and the other end point is on the edge of the preset closed area, and the preset closed area can be circular or oval , square, etc.
[0028] Specifically, when the preset closed area is a circular area, one end point of the at least one target trajectory coincides with the center of a circular area, and the other end point is on the circle of the one circular area, The vector of the target trajectory uses an endpoint on the circle of the one circular area as a starting point, and an end point coincident with the center of the one circular area as an end point.
[0029] 102. When the at least one target trajectory exists and each target trajectory corre...
Embodiment 2
[0043] This embodiment provides a method for unlocking the touch screen, such as image 3 As shown, the method includes:
[0044] 301. Acquire a touch track.
[0045] 302. Determine whether there is at least one target track in the touch track.
[0046]Wherein, one endpoint of the at least one target trajectory coincides with the center of a preset closed area, and the other end point is on the edge of the preset closed area, and the preset closed area can be circular or oval , square, etc.
[0047] Specifically, when the preset closed area is a preset circular area, one end point of the at least one target trajectory coincides with the center of a preset circular area, and the other end point is at the center of the preset circular area. On the circle of the area, the vector of the target trajectory takes the endpoint on the circle of the one preset circular area as the starting point, and takes the end point coincident with the center of the circle of the one preset circu...

Abstract
The embodiment of the invention discloses a method and a device for unlocking a touch screen. The method comprises the following steps of: firstly, determining whether a touch trajectory has at least one target trajectory, wherein one end point of the at least one target trajectory is coincident with the center of a predetermined closed region, while the other end point of the at least one target trajectory is located at the edge of the predetermined closed region; when the at least one target trajectory exists and each target trajectory corresponds to a predetermined closed region independently, respectively detecting whether the vector of each target trajectory is as the same as the gravity vector in direction according to gravity sensing, wherein the starting point of the vector of the target trajectory is the end point on the edge of the predetermined closed region and the terminal point of the vector of the target trajectory is the end point coincident with the center of the predetermined closed region; and finally, when the vector of each target trajectory is as the same as the gravity vector in direction, performing unlocking. The method and device for unlocking the touch screen are applicable to field of communication systems.
Description
technical field [0001] The invention relates to the field of communication systems, in particular to an unlocking method and device for a touch screen. Background technique [0002] G-sense (gravitation sense) is a sensor in the mobile phone that can sense the current acceleration or direction of gravity of the mobile phone. At present, the G-sense function has become a standard configuration of Android (Android) smart phones. At the same time, it is very common to use the G-sense function to implement various applications in Android smart phones. However, it is still blank to realize the unlocking of the touch screen through the gravity sensing technology. Contents of the invention [0003] Embodiments of the present invention provide a method and device for unlocking a touch screen, which implements the unlocking of the touch screen through gravity sensing technology, and makes up for the gap in the prior art. [0004] The technical scheme that the embodiment of the pr...
