+Driver Technology</title><shortdesc>Describes how screen coordinates work with the Digitizer Driver.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The digitizer hardware provides coordinate values that are digitized raw
+voltage values. These values are not the same as screen coordinates, which
+are based on pixel positions. The digitizer converts the raw values into screen
+coordinates and vice-versa. </p>
+<p>Screen coordinates always have their origin at the top left hand corner
+of the screen, but the digitizer has no such constraint - its origin, orientation
+and scaling are generally different from the screen coordinate system. This
+means that the digitizer needs to be calibrated so that digitizer coordinates
+can be translated to screen coordinates. </p>
