Some industrial cabinets use an external (trackpad/pointing device) connected via USB or PS/2. These require a different approach, as they do not have a physical screen.
The goal of calibration is to find a transformation matrix that converts Physical Coordinates $(X_p, Y_p)$ into Logical Coordinates $(X_l, Y_l)$. mcgs hmi touch calibration
