Terminal and touch method thereof

Abstract

The invention relates to the technical field of electronics and discloses a terminal and a touch method thereof. The terminal comprises a fingerprint recognition key; the fingerprint recognition key is capable of operating the terminal to finish predefined tasks according to a distance at which a user's finger moves on the fingerprint recognition key. The touch method includes: periodically receiving fingerprint information of the user's finger on the fingerprint recognition key, and acquiring fingerprint features in the fingerprint information each time the fingerprint information of the user's finger is received; according to positional information of the fingerprint features acquired in the preset period, calculating displacements of the fingerprint features during the preset period which is longer than a receiving period of the fingerprint information; according to magnitudes and directions indicated by the displacements of the fingerprint features, controlling the terminal to finish the predefined tasks. The terminal and the touch method thereof are applied to finishing the predefined tasks via the fingerprint recognition key, such as functions of moving a cursor or an image in various directions, scrolling a screen, turning pages and turning on or off the terminal.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a terminal touch method and the terminal. Background technique [0002] The home button was first proposed by Apple and used in terminals. The home button is the main function key of the terminal. The functions of the home button include, for example: press the home button once to return to the main interface or light up the screen, and double-click the home button to display a background running program. [0003] Fingerprint readers are currently used in many fields, such as notebook computers, which can be used to uniquely identify the owner of the terminal through the sensor in the fingerprint reader, that is, the fingerprint reader can only identify the fingerprint of the owner of the notebook computer. The owner's fingerprint unlocks and decrypts the laptop, and the fingerprint reader of anyone other than the owner cannot recognize the fingerprint, so that anyon...

AI Technical Summary

Problems solved by technology

[0004] Apple took the lead in combining the fingerprint reader with the home button to realize the identification of the Apple terminal and increase its security. However, the usual functions similar to the mouse, such as turning pages, scrolling, enlarging or reducing pictures, etc., are all through the terminal. It is realized by touch screen, and the home button cannot realize functions similar to a mouse, such as turning pages, scrolling, zooming in or zooming out pictures, etc.

Therefore, the function of the home button is relatively single and not powerful enough
