A touch control method for a terminal and a terminal

Abstract

The invention relates to the field of electronic technology, and discloses a touch control method of a terminal and a terminal. The terminal includes a fingerprint recognition key, and the terminal can be controlled to complete a predefined task according to the distance and direction of a user's finger moving on the fingerprint recognition key. The touch method of the terminal includes: periodically receiving the fingerprint information of the user's finger on the fingerprint identification key, and collecting the fingerprint features in the fingerprint information each time the fingerprint information of the user's finger is received; According to the location information of the fingerprint feature, calculate the displacement of the fingerprint feature within the preset time, the preset time is longer than the receiving cycle of the fingerprint information; according to the size and direction of the fingerprint feature displacement indication, the control terminal completes Pre-defined tasks. The touch method of the terminal and the terminal are used to use fingerprint recognition keys to complete predefined tasks, such as moving a cursor or picture in various directions, scrolling, turning pages, turning on and off a machine, and the like.

Description

Technical field [0001] The present invention relates to the field of electronic technology, and in particular to a touch method of a terminal and a terminal. Background technique [0002] The home button was first proposed by Apple and produced and used on the terminal. 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, double-click the home button, and a background program will appear. [0003] Fingerprint readers are currently used in many fields, such as laptop computers, which can be used to uniquely identify the holder of the terminal through the sensor in the fingerprint reader, that is, the fingerprint reader can only recognize the fingerprint of the owner of the laptop. The owner’s fingerprint unlocks and decrypts the laptop, and the fingerprint reader of anyone except the owner is unrecognizable, so no one except the owner can un...

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
