What is a graphic tablet and what’s its functionality?

A graphics tablet (also known as a digitizer, digital graphic tablet, pen tablet, drawing tablet, or digital art board) is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. 
In a very long period of time, it’s being recognized as a high-end device only for professional designer or artist because of the exorbitant cost.
The principle behind the core technique that allows graphic tablet to detects the movement of your pen is actually pretty simple, the panel inside the pen tablet will create an electromagnetic field on the surface of the tablet, when you are using the uniquely designed passive electromagnetic resonance pen (EMR stylus) on the working area, the circuit inside this little pen will cut the magnetic field line which will lead to the change of electric current. The tablet detects the changing current and then calculates the position of the pen.
