Sutherland leaves the inspiring idea of complete sensory interaction with anything user can imagine with a computer.ġ966 "Sword of Damocles"head-mounted display was invented by Sutherland at University of Utah.It is called sword of Damocles because it had to be suspended from the ceiling off set most of the weigt from the head of the user. Beyond Reality: "There is no reason why the objects displayed by a computer have to follow ordinary rules of physical reality with which we are familiar" (Ivan Sutherland).Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal." (Ivan Sutherland) Realism: "A chair displayed in such a room would be good enough to sit in.is like a looking glass into a mathematical wonderland" (Ivan Sutherland) Data visualization "A display connected to a digital computer.He introduces a term call kinesthetic display, which allows one to use all their senses to interact with and gain knowledge from a computer. Sutherland discusses the future possibilities with a computer display, that a person can use all their senses to interact with a computer. Knobs, Joysticks useful in adjusting parameters of computation, adjusting the viewing angle of a perspective view is usually being handled by joysticks.Light pen, RAND Tablet stylus(1964) useful in displaying items and in drawing or printing for input to the computer.Typewrite keyboards inexpensive, reliable, and produce easily transmitted signal.Sketchpad pioneered the concepts of graphical computing, the ability to zoom in and out on the display including grabbing objects, moving thm, changing size and using constraints. By using the light pen, user can also manipulated the drawings, duplicated them and stored them. The innovative feature of the sketchpad system was the user can create engineering drawings directly on the screen with a light pen. Has magnetic tape storage, typewrite keyboard, a Xerox printer, a light pen and an 9 inch CRTĬreate engineering drawings directly on the screen with a light pen. The system was his MIT doctorial thesis and Sketchpad system was the pioneering concepts of graphics computing, also the first graphical user interfaceįirst program that allowed the user to create graphical images directly on the computer screen Sketchpad system was invented In 1963, the first significant contribution has made by Ivan Sutherland.
