Problems solved by technology

[0005] Most of the current custom pattern unlocking methods based on trajectory recognition use image recognition to compare the actual input pattern with the preset pattern, while the similarity comparison method based on image recognition has precision and resource consumption. If high precision is required, the existing image recognition methods need to occupy more system resources for this purpose; if less system resources are required, the recognition accuracy will be reduced accordingly.
The amount of system resources occupied will directly affect the user experience, especially when there are a large number of programs running in the background, and when more system resources are occupied for image similarity calculation and recognition, it is actually not suitable for smart mobile terminals. Lightweight application platform, which makes the user experience poor

Abstract

This application discloses a function triggering method, which is different from the existing method of judging whether the actual input trajectory pattern is consistent with the preset standard trajectory pattern based on the principle of image recognition. The direction of the trajectory line segment is compared horizontally to judge the consistency between the two, and the calculation of the similarity of the image is converted into the calculation of the direction value. The latter can be easily calculated directly based on the coordinates of each trajectory point, and does not need to be based on the whole like the former. The image is calculated with the help of complex algorithms, which can significantly reduce the computational complexity, thereby reducing the amount of system resources that need to be occupied. It is more suitable for various lightweight smart mobile terminals, and the user experience is better. The present application also discloses a function triggering system, device and computer-readable storage medium at the same time, which have the above-mentioned beneficial effects.

Description

technical field [0001] The present application relates to the technical field of condition triggering, and in particular to a function triggering method, system, device and computer-readable storage medium. Background technique [0002] The continuous advancement of electronic informatization has brought new prosperity to modern society, which can be glimpsed from the changes in the way functions are triggered on computer terminals. [0003] Initially, the operating system based on the command line realized the triggering of the corresponding function by inputting a fixed function code. At this stage, the function must be realized by professional operators. It is very common that the function cannot be realized due to incorrect input. Later, a graphical operating system appeared. Programmers used different graphics to encapsulate some fixed function codes on the upper layer. At this stage, they could directly use the mouse or keyboard to trigger the corresponding function by...
