Unlocking method of touch screen terminal

Abstract

The invention discloses an unlocking method of a touch screen terminal. The method comprises the following steps of: lightening the screen by a sent screen unlocking triggering signal, displaying a gesture recognition region on a touch screen, and detecting a touch signal input by a user in the gesture recognition region; when the user touches the gesture recognition region, starting an imitative fingerprint scanning unlocking program, displaying a row of light beams in the region, repeatedly moving along the horizontal direction at constant speed to simulate the fingerprint scanning action, and continuing until the touch signal disappears; and calculating and recording the movement path data of the light beams, when the movement path satisfies a preset unlocking condition, executing the screen unlocking instruction. The method provided by the invention is used for touch screen terminals, such as a mobile phone and a flat computer, can bring the use experience of simulating fingerprint recognition to the user, the real fingerprint recognition is replaced by matching the movement paths of the light beams simulating the fingerprint scanning, the interestingness is increased, the science and technology experience is very strong, extremely high technical requirement and hardware cost caused by fingerprint recognition are avoided, and a certain peeping prevention effect is realized.

Description

technical field [0001] The present invention relates to an unlocking technology, in particular to an unlocking method for a touch screen terminal. Background technique [0002] With the development and maturity of the touch screen technology, the touch screen has gradually become a common accessory of mobile terminal devices, such as mobile phones, digital cameras, and tablet computers. In order to prevent misoperations such as accidental opening of the touch screen terminal, the touch screen terminal can be locked by detecting no operation within a certain period of time or using a specific function key to perform a lock operation on the touch screen. When the touch screen terminal is in the locked state, the touch screen terminal can be unlocked by using the input characteristics of the touch screen, such as by using virtual key input. [0003] There are many methods of unlocking through the touch screen, such as a slider unlocking method, a gesture unlocking method, a dr...

AI Technical Summary

Problems solved by technology

The above unlocking methods are generally sliding input in a fixed area. Long-term operation will easily cause the touch screen in this area to wear out and the accuracy of the sensor will decrease.

[0004] In addition, there is unlocking through password verification to improve confidentiality, but it is necessary to enter a string of numbers or letters, which is cumbersome to operate, and in actual daily life, such high security is often not required

However, other existing unlocking methods only pay attention to efficiency and eliminate the possibility of misoperation, the operation mode is relatively single, the operation interface is boring, and the entertainment is very low.
