Aiming at the problem in the related art that when unlocking a portable electronic terminal, it is necessary to go to a specific position of the touch screen to perform a specific unlocking operation, which causes inconvenience to the user. Embodiments of the present invention provide a portable electronic terminal, and an unlocking method and device for the portable electronic terminal. When unlocking the portable electronic terminal, the portable electronic terminal can be unlocked when the moving speed of the contact with the touch screen is greater than the preset value, and the unlock operation can be performed at any position on the touch screen, thereby facilitating the user to unlock the operation and improving the user experience, especially Suitable for portable electronic terminals with larger screen sizes.

According to an embodiment of the present invention, a method for unlocking a portable electronic terminal is provided. As shown in FIG. 1, the method may include the following steps (step S102-step S106):

Step S102, detecting contact with the touch screen of the portable electronic terminal.

Portable electronic terminals such as mobile phones, tablet computers, and personal digital assistants (PDAs) increasingly use touch screens as displays and user input devices. Users can interact with terminals by touching the touch screen positions corresponding to user interface objects , greatly improving the user experience. However, portable electronic terminals using touch screens have the problem of inadvertently activating or deactivating some functions due to accidental touches on the screen, so it is usually necessary to set a lock screen for protection. When users need to interact with the terminal, through specific method to unlock. When the touch screen is in the lock screen state, a lock screen prompt can be displayed on the touch screen, and the touch screen is in the detection state, which can detect contact with the touch screen.

In the embodiment of the present invention, in order to enable the user to perform the unlocking operation conveniently, the user can perform the unlocking operation anywhere on the touch screen of the portable electronic terminal. For example, when the user uses a portable electronic terminal with a large screen size, it is not necessary to loosen Open one hand, go to the designated position to perform the unlocking operation, and perform the unlocking operation on the edge of the touch screen. For this purpose, it is possible to detect contact with the touch screen at any position. Moreover, a visual prompt may be displayed on the touch screen to prompt the user to perform an unlocking operation, for example, an image and/or text is used to prompt the user to unlock.

Step S104, obtaining the moving speed of the above-mentioned contact while maintaining the continuous contact with the touch screen.

After the contact with the touch screen is detected, it is judged whether to maintain continuous contact with the touch screen and move on the touch screen. The speed at which the above contact moves while in contact. In a preferred implementation of the embodiment of the present invention, the movement distance of the above-mentioned contact can be obtained while maintaining continuous contact with the touch screen within a preset time interval, and the movement distance of the above-mentioned contact can be calculated according to the preset time interval and the obtained movement distance speed.

After obtaining the movement speed of the above-mentioned contact while maintaining the continuous contact with the touch screen, compare the obtained movement speed with the preset movement speed value, and judge whether to unlock the portable electronic terminal according to the comparison result.

Step S106, unlocking the portable electronic terminal if the moving speed of the contact reaches a preset threshold.

If the acquired moving speed of the contact reaches a preset threshold, the portable electronic terminal is unlocked, and the portable electronic terminal enters an unlocked state, and the user can interact with the terminal through the touch screen. In practical applications, the moving speed required for unlocking the portable electronic terminal can be set, so as to respond to the user's unlocking operation according to different user requirements.

Through the embodiment of the present invention, the portable electronic terminal is unlocked according to the moving speed of the touch screen while keeping in contact with it. When the moving speed reaches the preset threshold, the portable electronic terminal can be unlocked, which is convenient for the user to perform the unlocking operation and improves the user experience.

Step S304, the touch screen is in a contact detection state.

Step S306, the user touches the screen.

In step S308, an unlock prompt is displayed on the screen.

Step S310 , detecting whether the user maintains contact with the screen, if not, the unlock prompt disappears, and the screen lock prompt is displayed again; otherwise, the unlock prompt remains displayed.

Step S312, the user's finger slides on the screen.

In step S314, it is judged according to predetermined rules whether the sliding speed reaches the preset value, and if not, return to step S310; if the sliding speed reaches the preset value, the unlocking action is executed. Wherein, the predetermined rule is to continuously obtain the moving distance on the screen according to the preset time period, and calculate the moving speed accordingly.

Step S316, the unlocking is successful, the unlocking prompt disappears, and the user interface is entered.
