A method and system for quickly drawing a circular trajectory

Abstract

The invention discloses a method and system for quickly drawing a circular trajectory. The method includes the following steps: Step 1. When the mobile terminal is in a standby state, detect in real time whether a touch circular trajectory is generated on the touch screen; It is determined that the mobile terminal has a lighted touch screen operation when the trajectory is shaped; step 2. collects the coordinates of the touch circular trajectory; step 3. obtains the clock direction sequence of the circular trajectory according to the coordinates of the circular trajectory, and the clock direction sequence includes Clockwise and counterclockwise; step 4. Calculate the four coordinate points of the tangent line along the edge of the circular trajectory, draw a circular trajectory that coincides with the generated touch circular trajectory according to the order of the clock direction, and light up the screen. In the standby mode of the present invention, the user operates a circular gesture to light up the screen, and only needs to obtain the four coordinate points and the order of the clock direction for drawing the edge tangent of the circular trajectory, to quickly draw a circular rule, quickly light up the screen, and improve user experience.

Description

technical field [0001] The invention relates to black screen gesture technology, in particular to a method and system for quickly drawing a circular trajectory. Background technique [0002] At present, what people usually refer to as the standby state refers to the state in which electronic devices such as mobile phones or computers are turned on but do not perform any substantive work (and do not perform various operations on files and programs). [0003] The standby state of the mobile phone refers to the power-on state without any operation. The network signal is strong and stable, and the longest standby time test can be performed when the SIM card is not inserted (this is also the longest standby time indicated in the mobile phone manual). ——Detecting the standby state What we usually get when we use it (that is, when the SIM card is inserted) is the normal standby state or the use standby state. Indicates that the mobile phone is turned on and waiting for calls to be...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the power button is pressed every time the screen of the mobile phone is turned on. After a long time, the power button should be the first broken button, and it is troublesome to press the power button every time the screen is turned on.

In addition, in the standby mode, when the user operates a black screen gesture, the touch points are collected one by one on a modern smartphone and drawn one by one, which takes a long time to draw, and the time for the phone to turn on the screen is long, and the user experience is very poor.
