Sutherland invented Sketchpad in 1962 while at MIT. Claude Shannon signed on to supervise Sutherland's computer drawing thesis.[2] Among others on his thesis committee were Marvin Minsky and Steven Coons. Sketchpad was an innovative program that influenced alternative forms of interaction with computers. Sketchpad could accept constraints and specified relationships among segments and arcs, including the diameter of arcs. It could draw both horizontal and vertical lines and combine them into figures and shapes. Figures could be copied, moved, rotated, or resized, retaining their basic properties. Sketchpad also had the first window-drawing program and clipping algorithm, which allowed zooming. Sketchpad ran on the Lincoln TX-2 computer.
From 1965 to 1968, Sutherland was an associate professor of electrical engineering at Harvard University. Work with student Danny Cohen in 1967 led to the development of the Cohen–Sutherland computer graphics line clipping algorithm. In 1968, with his students Bob Sproull, Quintin Foster, Danny Cohen, and others he created the first head-mounted display that rendered images for the viewer's changing pose, as sensed by The Sword of Damocles, thus making the first virtual reality system. A prior system, Sensorama,[15][16] used a head-mounted display to play back static video and other sensory stimuli. The optical see-through head-mounted display used in Sutherland's VR system was a stock item used by U.S. military helicopter pilots to view video from cameras mounted on the helicopter's belly.
From 1974 to 1978 he was the Fletcher Jones Professor of Computer Science at California Institute of Technology, where he was the founding head of that school's computer science department. He then founded a consulting firm, Sutherland, Sproull and Associates, which was purchased in 1990 by Sun Microsystems to form the seed of its research division, Sun Labs.[17][18]
Computer History Museum Fellow "for the Sketchpad computer-aided design system and for lifelong contributions to computer graphics and education", 2005[20]
IEEE Emanuel R. Piore Award – [29] 1986 "For pioneering work in the development of interactive computer graphics systems and contributions to computer science education."
"A display connected to a digital computer gives us a chance to gain familiarity with concepts not realizable in the physical world. It is a looking glass into a mathematical wonderland."[36]
"The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal."[36]
When asked: "How could you possibly have done the first interactive graphics program, the first non-procedural programming language, the first object oriented software system, all in one year?", Sutherland replied: "Well, I didn't know it was hard."[37]
Oral history interview with Ivan Sutherland at Charles Babbage Institute, University of Minnesota, Minneapolis. Sutherland describes his tenure as head of the Information Processing Techniques Office (IPTO) from 1963 to 1965. He discusses the existing programs as established by J. C. R. Licklider and the new initiatives started while he was there: projects in graphics and networking, the ILLIAC IV, and the Macromodule program.
On May 28, 2006, Ivan Sutherland married Marly Roncken.[40] He has two children.[citation needed] His elder brother, Bert Sutherland, was also a computer science researcher.[41]
