Sketch Pad

SketchPad was the first interactive drawing program, written in 1963 by IvanSutherland as the basis of his tour-de-force thesis. It included visual constraints, character recognition, freehand drawing with smoothing, and animation.

AlanBlackwell of the University of Cambridge is working with IvanSutherland to make a new electronic edition of the thesis available online, in late 2003. In the meantime, the original can be viewed at

It is now available as a PDF at

AlanKay insists that all of user interface design for the last 30 years was done in SketchPad first (and then some). He has the videos to prove it. -- He also credits it as the first ObjectOriented system and an important influence on SmalltalkLanguage.
