Sketchpad
The earliest graphical manipulation program was called Sketchpad. Created in 1963 by Ivan Sutherland, a grad student at MIT, Sketchpad allowed the user to manipulate objects on a CRT (cathode ray tube).Sketchpad eventually led to the creation of the Rand Tablet for work on the GRAIL project in 1968, and the very first tablet was created. Other early tablets, or digitizers, like the ID (intelligent digitizer) and the BitPad were commercially successful and used in CAD (Computer Aided Design) programs. Modern day tablets are the tools of choice by digital painters. WACOM is the industry leader in tablets which can range in size from 4” x 6” all the way to 12” x 19” and are less than an inch thick.
Tablets
The idea of using a tablet to communicate directions to a computer has been an idea since 1968 when the RAND (Research and Development) company out of Santa Monica, developed a tablet that was used to program.[6] Digitizers were popularized in the mid 1970s and early 1980s by the commercial success of the ID (Intelligent Digitizer) and BitPad manufactured by the Summagraphics Corp. These digitizers were used as the input device for many high-end CAD (Computer Aided Design) systems as well as bundled with PC's and PC based CAD software like AutoCAD.
