Error correcting method for touch screen

Abstract

The invention provides an error-correcting method for a touch panel, which comprises the following steps: recording effective clicking coordinate points, moving coordinate points and lifting coordinate points respectively, comparing the coordinate points and determining whether the moving coordinate points and the lifting coordinate points are in a preset effective sensing zone, thereby accurately determining the effectiveness of clicking and moving events. The method can effectively avoid the misoperation and enhance the operation sensibility.

Description

technical field [0001] The invention relates to the technical field of touch screen input, in particular to an error correction method for the touch screen. Background technique [0002] The mouse is a very important computer input device, which is composed of left button, middle button, right button, scroll wheel, etc. The functional operations on the screen can be completed through mouse movement and mouse buttons. The original intention of the mouse design is to make the operation of the computer easier. , Anyone who has used a computer knows the importance of the mouse. A very important feature of the mouse is that when the mouse moves on the computer screen, it moves pixel by pixel, so its coordinate positioning on the screen is very precise, and it can be achieved that every pixel is not bad. When the mouse moves to a certain point on the screen, press the left or right button of the mouse, and then release the button, a mouse event will be responded, which can achiev...

Problems solved by technology

[0004] When fingers are used on the touch screen, there are two problems: one is that human fingers vary in thickness, which can easily cause pixel errors, and if the finger is tilted on the screen at a relatively large angle, multi-point positioning may occur. There will be click errors. Use your fingers to complete the click operation on the screen. The best click angle is 70-110°, otherwise there may be inaccurate clicks, erratic clicks or no response; the second is that everyone’s fingers are in a suspended state There may be shaking phenomenon. When the finger shakes, the click target will shift, or the click becomes a double click, or the click becomes a movement. For example, when the finger is pressed on an object, the coordinates are ( 10, 10), but after pressing it down, the finger shakes again at the same time. During the shaking process, it moves about two pixels and becomes (12, 12), so the system will think that this operation is a 2 pixel movement without responding to the original click

When we do some operations on the touch screen, if we encounter objects in one, three, or four ways, there is basically no major problem in operation, such as buttons with events, the range of finger clicks is on the entire object, that is, as long as the finger's Clicking on its object regardless of whether the finger has moved or not, as long as the finger is still in the object area when it leaves the screen area, it will accurately respond to the click and move events. These methods use fingers to operate, basically nothing too big problem, but the tilt angle should not be too large when clicking, otherwise there may be pixel errors

For the second method above, if you use your fingers to operate, unexpected results will often appear. When you click a file with your fingers, if you shake your fingers at this time, you will find that it has become a moving file, like This phenomenon of object movement caused by finger shaking has not yet been specifically targeted in the Windows operating system.
