touch tablet
or drawing tablet; a large flat surface that a user can touch with a hand or a pen (or a puck) to control the position of the pointer on the screen. Touch tablets typically work in absolute coordinates, meaning that each point on the tablet maps to a specific point on the screen, rather than relative coordinates, which is common for a mouse and many other input devices. Absolute coordinates are important for applications requiring precision drawing or the copying of drawings, which can be accomplished by laying a drawing over the tablet and tracing it with a pen or puck.
