The Sketchpad uses drawing as a novel communication medium for a computer. Sketchpad was able to do just this, creating highly precise drawings, and also introduced important innovations such as memory structures to store objects and the ability to zoom in and out. He imagined that one should be able to draw on the computer. TX-2 included a nine inch CRT and a light pen which first gave Sutherland his idea. Sketchpad ran on the Lincoln TX-2 computer, an innovative machine designed in 1956 (it had a large amount of memory for its time: a vacuum-tube-driven core of 64K words, a faster, transistor-driven core of 4K words, a paper-tape reader and could also use magnetic tape as auxiliary storage.) TX-2 was an “on-line” computer (at that time most computers would run “batches” of jobs and were not interactive), used to investigate the use of Surface Barrier transistors for digital circuits. Sketchpad, in turn, influenced Douglas Engelbart’s NLS (oN-Line System). Sketchpad was influenced by the conceptual Memex of Vannevar Bush, as it was envisioned in his fundamental paper “As We May Think”. For his Ph.D., Sutherland went to MIT (Massachusetts Institute of Technology) were he studied under Claude Shannon and Marvin Minsky and developed his revolutionary thesis, Sketchpad, A Man-Machine Graphical Communication System, the first Graphical User Interface. also in Electrical Engineering from the Caltech (California Institute of Technology). Sutherland went on the study at Carnegie Mellon University, where he earned a Bachelor’s degree in Electrical Engineering and then went on to earn a M.S. Ivan and his brother Bert even met Berkeley and were inspired to envision new avenues for programming. This program was a great accomplishment, it was the longest program ever written for Simon, a total of eight pages of paper tape. To make division possible, he added a conditional stop to Simon’s instruction set. Ivan’s first big computer program was to make Simon divide. His first computer experience was with the famous computer Simon of Edmund Berkeley. He introduced concepts such as 3-D computer modeling, visual simulations, computer aided design (CAD), virtual reality, etc. thesis, named Sketchpad, which is one of the most influential computer programs ever written by an individual, Sutherland has contributed numerous ideas to the study of Computer Graphics and Computer Interaction. Sketchpad, for example, was used to develop cutting-edge object-oriented programming and the graphical user interface (GUI).įor creating Sketchpad, Ivan Sutherland got the Turing Award in 1988 and the Kyoto Prize in 2012.Ivan Sutherland is considered by many to be the creator of Computer Graphics and an Internet pioneer. It is also recognized as an important step forward in the development of computer graphics. Sketchpad is regarded as the origin of today's computer-aided design (CAD) software. Sketchpad was a pioneer in the field of human-computer interaction (HCI). Ivan Sutherland created Sketchpad, a groundbreaking computer software. It also had the ability to alter an image that had already been drawn. ![]() It was simpler to design very accurate and repetitive drawings using Sketchpad. Sketchpad was a one-of-a-kind technology that aided in the understanding of processes such as the concept of links, which could be conveyed visually. Drawing scientific, mechanical, mathematical, electrical, and animated designs was a breeze using Sketchpad. ![]() The system had input, output, and computation routines that enabled it to decode data drawn directly on a computer screen. It was a "live" computer that was used to test the use of surface-barrier transistors in digital circuits.ĭrawing was used as the computer's unique interaction medium in Sketchpad. Sketchpad was based on the revolutionary Lincoln TX-2 computer, which was released in 1956. This ring structure provided immediate topological information processing, which eliminated the need for any searching. The drawings created using Sketchpad were saved in the computer's custom constructed ring structure. It offered the "ring" list structure and used value inference to solve constraints. ![]() Sketchpad allowed users to draw on a computer screen with a light pen. Sketchpad also has certain CAD functions, such as the ability to calculate loads on beams. It could handle restrictions for example, drawing a restricted ellipse resulted in a circle. Ivan Sutherland released Sketchpad on December 7, 1963, demonstrating that computer graphics can be used for both technical and aesthetic applications in addition to being a revolutionary technique of Human Computer Interaction.
