X-Y digitizing tablet:  A peripheral device for manually translating line and point data (like engineering and technical drawings) into some computer format (usually vector or CAD).  The drawing is secured to the tablet, and the operator positions the device’s cursor (which may look like a pen or a computer mouse with a crosshair lens) over lines and other elements, clicking a button or pressing a key to record a coordinate.
