Definition - What does Sketchpad mean?
In 1988 and 2012, Ivan Sutherland received the Turing Award and the Kyoto Prize, respectively, for designing Sketchpad.
Sketchpad is also known as Robot Draftsman.
Techopedia explains Sketchpad
Sketchpad permitted users to sketch on a screen using a light pen. It solved constraints with the help of value inference and presented the "ring" list framework. The drawings done using Sketchpad were stored in this specially engineered ring structure within the computer. This ring structure included instant processing of topological information, which required no searching at all.
Sketchpad operated on the Lincoln TX-2 computer, which was a revolutionary machine developed in 1956. It was an "online" computer designed to check the usage of surface-barrier transistors for digital circuits.
Sketchpad made use of drawing as a computer's unique interaction medium. The system consisted of input, output as well as computation programs that allowed it to decipher information sketched directly on a computer screen. Sketchpad was valuable in drawing scientific, mechanical, mathematical, electrical and animated drawings.
Sketchpad was a unique system and helped especially in understanding processes like the concept of linkages, which could be explained using pictures. With Sketchpad, it was easier to draw highly accurate and highly repetitive drawings. It also featured the option to edit a previously drawn picture.
