Fingerprint navigation method and fingerprint navigation signal generation device

Abstract

One embodiment of the invention relates to the computer field and discloses a fingerprint navigation method and a fingerprint navigation signal generation device. The fingerprint navigation method comprises following steps: when finger pressing is detected, entering in navigation detection and obtaining a group of fingerprint images; performing accumulative calculation on current sliding displacement of the finger according to preset navigation parameters and the group of fingerprint images; determining whether the sliding displacement meets a preset condition and generating fingerprint navigation signals if the sliding displacement meets the preset condition; detecting whether or not the finger is taken off and entering navigation detection again if it is detected that the finger is not taken off. The embodiment of the invention also provides a fingerprint navigation signal generation device. Compared with the prior art, the implementation method of the invention realizes constant navigation through fingerprint identification, which facilitates the navigation operation for users, enriches application scenarios of navigation function based on fingerprint identification modules and further improves the touch control experience of navigation function based on fingerprint identification modules.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a fingerprint navigation method and a fingerprint navigation signal generation device. Background technique [0002] With the increasingly fierce competition in the mobile phone industry, major mobile phone manufacturers have made some innovations for the user experience of mobile phones. For example: Apple has combined the fingerprint identification module with the home button, integrating multiple functions of the home button. Press the home button once, and the phone will turn on the screen or return to the main interface; double-click the home button, and the multitasking interface will appear; touch the home button with your finger, and fingerprint recognition will be performed when needed, such as unlocking the phone, fingerprint payment, etc. [0003] Huawei, vivo and other mobile phone manufacturers have followed suit, implanting fingerpri...

[0004] However, the current omnidirectional navigation function based on the fingerprint recognition module is not perfect enough. If the user wants to use this omnidirectional navigation function to operate the mobile phone to continuously turn pages, he needs to lift his finger after one swipe, and then press the button again. And slide, this operation is very inconvenient, especially when the fingerprint recognition module is installed on the back of the phone

In addition, in the application scenario of operating the mobile phone to adjust the volume, if the omnidirectional navigation function in the prior art is used, multiple operations are required, which affects the user experience
