A program that allowed users to draw on a screen with a {light pen}. It supported constraints (e.g. drawing a constrained ellipse produced a circle). It also had some {computer aided design} features (e.g. computing loads on beams). Sketchpad was the subject of Ivan E. Sutherland's 1963 MIT PhD thesis, which opened the field of computer graphics. It was the progenitor of computer drawing packages like MacDraw or Adobe Illustrator. There is a film of Sketchpad in action. It solved constraints using value inference and introduced the "ring" list structure. ["Sketchpad: A Man-Machine Graphical Communication System", I.e. Sutherland, MIT Lincoln Lab, TR 296 (Jan 1963)].

Sketchpad

Sketchpad (a.k.a. Robot Draftsman) is a computer program written by Ivan Sutherland in 1963 in the course of his PhD thesis, for which he received the Turing Award in 1988, and the Kyoto Prize in 2012. It pioneered human–computer interaction (HCI), and is considered the ancestor of modern computer-aided design (CAD) programs as well as a major breakthrough in the development of computer graphics in general. For example, the graphical user interface (GUI) was derived from Sketchpad as well as modern object-oriented programming. Using the program, Ivan Sutherland showed that computer graphics could be used for both artistic and technical purposes in addition to demonstrating a novel method of human–computer interaction.
