What Is a Graphic Tablet?
A graphics tablet or digitizer, is an alternative method of inputting data into a computer. It can take the place of a mouse and keyboard or work alongside them. Some of the best uses for graphics tablets are in art programs like Photoshop or CorelDraw. The graphics tablet lets the artist use a stylus like a pen or paintbrush to draw directly into a painting, picture or photograph that is being edited.

Intuitive Use
-
When we learn language skills in school, we are first taught to write with a pencil and then with a pen. Later on in our education, we may have a computer or typing class in which we learn to use the keyboard and a mouse. A graphics tablet is intuitive because it allows us to use a much older set of skills with a stylus in our hand.
How It Works
-
The surface of the graphics tablet has an area that is pressure-sensitive, and allows you to write by hand or draw directly on it. The stylus must be matched to the device, as not just any pressure will do. The stylus also usually includes buttons, like a mouse, and these buttons can be programmed with the same functions.

Layers and Pressure
-
The surface is also sensitive to how much pressure is being applied. With more pressure, the software may make a darker or wider line. This makes it easier for an artist who is accustomed to painting with a brush and using broad strokes on canvas.
Added Peripherals
-
Many graphics tablets come with a mouse that is used on the surface, as if the tablet was a mouse pad. This lets you save valuable desk space by not having two sets of mice. The mouse is a special device like the stylus, paired to the tablet. It will only work on the tablet, so it is important to keep a matched set.
Types and Sizes
-
There are many types and sizes of graphics tablets for every level of user. The leader in manufacturing graphics tablets is Wacom; other manufacturers like Aiptec and Digipro compete on several levels. For the professional Computer Aided Design (CAD) worker, there are large tablets that may cost hundreds or thousands of dollars and take up a whole desktop. For the casual artist and home user, there are smaller versions in the 9-inch-by-12-inch and under sizes. Some of the smaller ones in the 3-inch-by-4-inch range fit the smaller budget and are available for less than $50.
