Description

A kind of unlocking method of touch screen mobile terminal

technical field

  The invention relates to an unlocking method, in particular to an unlocking method applied to mobile terminals such as touch-screen mobile phones and tablet computers.

Background technique

With the rapid development of electronic technology, more and more touch-screen mobile terminals have entered people's daily life. Such as mobile terminals such as mobile phones and tablet computers, current touch-screen mobile terminals generally support the functions of locking and unlocking the screen. When a mobile terminal such as a mobile phone does not work for a period of time or the user uses a specific function key to lock the mobile phone, the mobile phone is in a locked state, thereby achieving the purpose of saving power and preventing misoperation when not in use. When the mobile phone is in a locked state, the user can unlock the mobile phone according to a preset unlocking method.

At present, there are many ways to unlock mobile phones. The most commonly used one is sliding unlocking, as well as button unlocking, gesture unlocking, fingerprint unlocking and Jiugong unlocking. Gesture unlocking includes single-point or multi-point touch. Unlocking gestures are preset in the mobile phone. When unlocking the mobile phone, the same gesture can be input on the input interface to unlock smoothly. However, the existing unlocking methods are relatively simple, and can be easily unlocked, and the security is low. Unlocking in the form of inputting a password has poor user experience, and the unlocking lacks entertainment and interest.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for unlocking a mobile terminal with a touch screen, which uses mathematical calculation formulas to unlock, reduces misoperations, and increases interest.

In order to solve the above technical problems, the present invention takes the following technical solutions:

A method for unlocking a mobile terminal with a touch screen, comprising the following steps:

(1) Wake up the mobile terminal, and the touch screen interface displays mathematical calculation formulas;

(2) Input the answer of the calculation formula on the touch screen interface;

(3) Determine whether the answer is correct;

(4) If yes, the unlock is successful; if not, the unlock fails.

The method also includes the steps of,

(5) After waking up the mobile terminal, whether the user can clearly see the mathematical calculation formula;

(6) If you can see it clearly, go to step (2) for subsequent processing; if you can’t see it clearly, change to another set of mathematical calculation formulas and go to step (5).

The mathematical operation formula is an arithmetic formula for addition, subtraction, multiplication and division of two numbers.

Both of the two numbers are single digits, and both numbers between 0 and 9 are randomly generated.

The present invention unlocks through mathematical calculation formulas, and needs to input correct calculation answers to successfully unlock, effectively reducing the probability of unlocking caused by misoperation, increasing the fun of operation, and bringing users a different operating experience.

    Accompanying drawing 1 is a schematic flow chart of the principle of the present invention.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

The invention discloses a method for unlocking a mobile terminal with a touch screen. The method uses mathematical calculation formulas to unlock the terminal. The user performs calculations according to the formula displayed on the screen and inputs the answer. Only when the correct answer is input can the unlocking be successful, which reduces errors. operate.

As shown in accompanying drawing 1, a kind of unlocking method of touch screen mobile terminal comprises the following steps:

(1) Wake up the mobile terminal, and the touch screen interface displays mathematical calculation formulas. Current mobile terminals such as mobile phones and tablet PCs usually lock the screen when not in use, so that it is in a locked state, and then wake up the screen by pressing a power button or other methods. After waking up, the touch screen will display a set of mathematical calculations. The operation formula is an operation formula for addition, subtraction, multiplication and division of two numbers, both of which are single digits, and are randomly generated from numbers between 0 and 9. For example, the calculation formula is 3+6, or 6-2, or 4*3, or 9/3, etc. Of course, it can also be other. The above list is not limited, and it can be any combination of two numbers. enumerate.

(2) Input the answer of the calculation formula on the touch screen interface. According to the displayed calculation formula, after the user calculates the answer, he inputs the answer on the touch screen.

(3) Determine whether the answer is correct.

(4) If the answer currently entered is correct, the unlocking is successful, and the mobile terminal is unlocked; if the answer is incorrect, the unlocking fails, and no input or other operations can be performed on the touch screen.

The method further includes the step of (5) after waking up the mobile terminal, whether the user sees the mathematical calculation formula clearly.

(6) If you can see the calculation formula clearly, go to step (2) to input the answer, and proceed with the next steps in sequence; if you can’t see clearly, the background program will automatically exchange another set of mathematical calculation formulas for the user to view, and you can click on the corresponding button to realize the exchange calculation formula, if setting a button that cannot be seen clearly, go to step (5). The user confirms again whether he has seen clearly, if he still cannot clearly see what the calculation formula shows, then the two dots cannot see the button again, and change a group of calculation formulas again until he can see clearly. Step (5) and step (6) are performed after step (1) and before step (2), to ensure that the user can clearly view the calculation formula.

It should be noted that the above description is not a limitation to the technical solution of the present invention, and any obvious replacements are within the protection scope of the present invention without departing from the inventive concept of the present invention.
