digitizer tablet - Computer Definition
A graphics drawing tablet used for sketching new images or tracing old ones. Also called a "graphics tablet," the user contacts the surface of the device with a wired or wireless pen or puck. Often mistakenly called a mouse, the puck is officially the "tablet cursor." For sketching, either the pen or puck is used. For tracing, the puck is preferred because its crosshairs, visible through a clear glass lens, lets you precisely pinpoint ends and corners of detailed drawings. Most tablets allow parts of the tablet surface to be customized into buttons that can be tapped to select menus and functions in the application. Digitizer Mode and Mouse Mode Tablets typically support two modes of operation. "Digitizer mode" creates a one-for-one correspondence between tablet and screen. Wherever the tablet is touched, the screen is drawn in the exact same location. In contrast, "mouse mode" moves the screen pointer relative to any starting position on the tablet surface, just like an ordinary computer mouse. The Output Is X-Y Coordinates When drawing or tracing on the tablet, a series of x-y coordinates (vector graphics) are created, either as a continuous stream of coordinates, or as end points.
