<p>A method and a device for unlocking a touch screen. The method comprises: determining whether at least one target trajectory exists in a touch 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, detecting whether the vector of each target trajectory is 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 when the vector of each target trajectory is the same as the gravity vector in direction, performing unlocking. The method and device for unlocking a touch screen are applicable to the field of communication systems.</p> |
