In one embodiment, if it is in the locked screen state, then compare and verify the current fingerprint with the predetermined unlocking fingerprint; if it is in the unlocked state, perform corresponding functional processing according to the operation mode of the finger;

If the coincidence degree of the current fingerprint and the predetermined unlocking fingerprint is equal to or greater than the preset threshold, unlock; if the coincidence degree of the current fingerprint and the predetermined unlocking fingerprint is less than the preset threshold, the screen lock state is maintained.

Or in another embodiment, if it is in the locked screen state, then keep the current locked screen state, and the fingerprint touch recognition area does not respond to any finger operation; if it is in the unlocked state, perform corresponding functional processing according to the finger operation mode.

The present invention also provides a system for a mobile terminal to realize the navigation key function based on fingerprint identification, including a fingerprint sensor integrated on the back of the mobile terminal, and

The setting unit is used to set the fingerprint touch recognition area on the back of the mobile terminal;

The fingerprint detection unit is used to detect whether there is a fingerprint touch operation in the fingerprint touch recognition area;

A judging unit for judging whether the finger operation on the fingerprint touch recognition area is a sliding operation or a clicking operation, and judging whether the current screen is in a locked screen state or an unlocked state;

The execution unit is configured to execute corresponding functional processing according to the operation mode of the finger.

The system further includes: a comparison and verification unit, configured to compare and verify the degree of coincidence between the current fingerprint and the predetermined unlocking fingerprint.

The present invention sets a fingerprint touch recognition area on the back of mobile terminals such as mobile phones, which is convenient for users to control the mobile phone with one hand, especially suitable for large-screen mobile phones, and solves the problem that the existing large-screen mobile phones are difficult to control with one hand. At the same time, slide or click on the back of the mobile terminal with your finger to unlock, or switch between the upper and lower pages of the web page, or realize the pause and play of video or sound, etc.

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 present invention discloses a method for a mobile terminal to realize a navigation key function based on fingerprint identification, as shown in Figure 1, the method includes the following steps:

A fingerprint touch identification area is set on the back of the mobile terminal. The fingerprint touch recognition area is a fixed area. The central area of the touch is the part of the index finger when holding the phone with one hand. The upper and lower widths are two fingers wide, and the length can be extended close to the edge of the screen. Of course, the width and length can be appropriately and flexibly adjusted in design, and it is not limited to remain unchanged.

When a fingerprint touch operation is detected in the fingerprint touch recognition area, it is judged whether it is a sliding operation or a click operation. The user can perform a sliding operation or a clicking operation on the fingerprint touch recognition area, and the sliding operation can be sliding left and right, or sliding up and down.

Execute corresponding functional processing according to the operation mode. If it is a sliding operation, according to the predetermined operation method, if you are currently browsing the webpage, you can swipe left and right to switch the webpage, swipe up and down to scroll the list, or swipe to switch between the upper and lower pages of the e-book, etc. The specific operation effect is the same as that in the The front of the screen is consistent, so I won't go into details here.

In addition, the method further includes the step of further judging whether the current screen is in a locked screen state when the fingerprint touch recognition area receives a sliding operation or a clicking operation with a finger. There are two preferred implementations.

Embodiment 1, as shown in FIG. 2 , if the screen is locked, the current fingerprint is compared with the predetermined unlocking fingerprint for verification. If the coincidence degree of the current fingerprint and the predetermined unlocking fingerprint is equal to or greater than the preset threshold, unlock; if the coincidence degree of the current fingerprint and the predetermined unlocking fingerprint is less than the preset threshold, the screen lock state is maintained. By setting a fingerprint verification to prevent others from using the mobile phone, it plays a certain protective role. According to this embodiment, the unlocking operation can be performed in the fingerprint touch recognition area, which does not conflict with the unlocking operation from the front of the screen. If it is in the unlocked state, perform corresponding functional processing according to the finger operation mode. However, if the current screen is in an unlocked state when finger operations are performed on the fingerprint touch recognition area on the back of the mobile terminal, corresponding functional processing is performed according to the specific operation mode.

Or another implementation mode, Example 2, as shown in FIG. 3, if the screen is locked when finger operation is performed in the fingerprint touch recognition area, the current lock screen state is maintained, and the fingerprint touch recognition area does not respond to any finger operation. If it is in the unlocked state, perform corresponding functional processing according to the finger operation mode. Under the second embodiment, the unlocking operation cannot be performed in the fingerprint touch identification area, and only by unlocking from the front of the screen, can the fingerprint touch identification area be used normally.

It should be noted that the fingerprint touch recognition area on the back of the mobile terminal does not conflict with the operation of the touch area on the front of the screen, but they operate independently. The operation is more flexible, and for a large-screen mobile phone, it can be operated while holding it with one hand.

In addition, the present invention also provides a system for a mobile terminal to realize navigation key functions based on fingerprint identification, including a fingerprint sensor integrated on the back of the mobile terminal, a setting unit, a fingerprint detection unit, a judgment unit and an execution unit. in,

The setting unit is used for setting the fingerprint touch identification area on the back of the mobile terminal.

The fingerprint detection unit is used to detect whether there is a fingerprint touch operation in the fingerprint touch recognition area.

The judging unit is used for judging whether the finger operation on the fingerprint touch recognition area is a sliding operation or a clicking operation, and judging whether the current screen is in a locked state or an unlocked state.

The execution unit is used to perform corresponding functional processing according to the operation mode of the finger. For example, when browsing the webpage, swiping left and right is to switch webpages, and swiping up and down is to scroll the list, etc., which is consistent with the operation mode on the front of the screen.

The system also includes a comparison verification unit, which is used to compare and verify the matching degree of the current fingerprint and the predetermined unlocking fingerprint, obtain the matching degree of the current fingerprint and the predetermined unlocking fingerprint, and check that the matching degree is related to the size of the predetermined threshold, So as to achieve the purpose of unlocking or maintaining the lock screen state.
