Touch the display coordinate system

- Feb 01, 2019-

Touch the coordinate system of the display screen, the touch screen is an absolute coordinate system, you can directly click where you want to choose, which is essentially different from the relative positioning system such as the mouse is the intuitiveness in place.Absolute coordinate system, is the feature of every position coordinates has nothing to do with the last position coordinates, touch screen in physics is a set of independent coordinate positioning system, every touch data through calibration into screen coordinates, so that this requires a touch screen coordinates, no matter under what circumstances, the output data of the same point is stable, if not stable, so the touch screen can't guarantee the absolute coordinates positioning.
