Embodiment Construction

[0034] The basic idea of ​​the present invention is: the user operates on the touch screen, and when the touch track forms a closed curve, calculates the area of ​​the closed curve and determines that the area of ​​the closed curve meets the preset unlocking determination conditions to unlock.

[0035] Touch screen unlocking method of the present invention, as figure 1 As shown, it mainly includes the following steps:

[0036] Step 101: Obtain and record the touch track formed by the user's unlocking operation on the touch screen in real time;

[0037] Step 102: When detecting that the touch track forms a closed curve, calculate the area of ​​the closed curve;

[0038] Step 103: Unlocking when it is determined that the area of ​​the closed curve meets the preset unlocking determination condition.

[0039] Here, the unlocking determination condition may specifically be: not less than a preset unlocking area threshold; wherein, the unlocking area threshold may be a default set...

Abstract

The invention discloses a touch screen unlocking method. The touch screen unlocking method comprises the following steps: a touch track formed by unlocking operation of a user on a touch screen is acquired and recorded in real time; the area of a closed curve is calculated when forming of the closed curve by the touch track is detected, wherein for detecting forming of the closed curve by the touch track, whether the touch track passes through the same touch point repeatedly is detected, and if yes, the touch track forms the closed curve; unlocking is performed when the area of the closed curve meets a preset unlocking judging condition. Correspondingly, the invention discloses a touch screen unlocking device. The touch screen unlocking method and device can prevent mistaken unlocking effectively, increase the unlocking efficiency and improve the user experience and are particularly suitable for middle-aged and elderly users.
