What is the graphic tablet?
The first tablets which are similar modern, appeared in 1964. Initially they were called “Grakofony”. And here the first tablets intended for the consumer market, already were called as CoalaPad.
Usually such device is used by designers and people who in general are engaged in creativity. Besides, such tablets can be used to transfer to the computer already ready image.
The graphic tablet represents the device, intended to enter into the computer drawings by hand.
There are tablets specially intended for professionals, and is for fans. So, professional tablets differ higher characteristics, at the expense of which they more expensive. Also engineering tablets, exacting to the accuracy, permission, the speed of data transmission and similar characteristics are allocated.
In the itself tablet is made by a feather and a flat tablet which is sensitive to pressing. Also special mouse can sometimes be applied to it. Work of modern tablets is based on the printing conductors located in the form of a grid. This grid represents feather steps from 3 to 6 millimeters, and a read-out step within hundred on millimeter. Along with the provision of a feather, modern tablets can define an inclination of this feather, pressing and the direction.
Allocate some types of tablets

· electrostatic
· on the basis of an electromagnetic resonance
· on the basis of piezoelectric effect.
On the basis of piezoelectric effect.
Rabochaya Square of graphic tablets is usually equated to paper formats, and, than it is more format, it is more expensive to those. Permission of a tablet, that is step of reading of information, is measured in dpi or dots per inch. Among the greatest values – more than 12 thousand of dpi. This expansion is supported by engineering tablets. To the ordinary user and even if also to the designer, such permission isn't necessary and requirements for part of productivity are met quite by tablets of average price range.
