As with most computers of that era, programs were written in macro-assembler, punched onto paper tape and fed into the computer’s paper tape reader. It was, at the time, one of the biggest machines in the world, with kilobytes of core memory. The program allowed users to visualize and control program functions and became a foundation for computer graphicscomputer operating system interfaces, and software applications that are used in many facets of modern technology.

The Regents of the University of California. If the user changed the master drawing, all the instances would change as well. Sutherland received the Turing Award from the Association for Computing Machinery in for the invention of Sketchpad. With the constraint system, it was possible to loosely sketch a shape, then add geometric and topological relationships to modify it into the exact shape you needed.

How objects in Sketchpad could be visualized and modeled on a screen became the foundation for modern graphical computing used in advertising, business, entertainment, architecture, and Web design. A Sketchpad user sketches sketchpas on a computer display with a “light pen. Keep Exploring Britannica Computer science. This facility was used to create alphanumeric character glyphs, and electrical schematic symbols.

Sketchpad encountered a critical challenge that remains central to human-computer interaction. Browse by Decades s s s s s s s s s s s. Sketchpad proved beyond doubt that computers could automate repetitive design and drafting tasks with a reliability and accuracy not possible by manual methods. Do You Need a Lobotomy? It is a tribute to Sketchpad’s uniqueness that it defined a GUI Graphical User Interface more than 20 years before the term was first used.

About the same time, Lawrence G. What was happening with interactive media at that time?

Thank you for your feedback. In most computers ran jobs in batch job mode only, using punched cards or magnetic tape reels submitted by professional programmers or engineering students.

Sketchpad allowed users to communicate the higher-level principles that defined their design, so that they could easily make changes and the system would automatically adjust the rest of the design, or other frames of an animation. Computer science, the study of computers, including their design architecture and their uses for computations,….

He co-founded Evans and Sutherland, where he did pioneering work in the field of real-time hardware, accelerated 3D graphics, and printer languages.

The system contains input, output, and computation programs which enable it to interpret information drawn directly on a computer display.

Sketchpad – Wikipedia

A set of push buttons controls the changes to be made such as “erase”, “move”, etc. Since the conditions can involve anything computable, Sketchpad can be used for a very wide range of problems. The user indicates conditions with the light pen and push buttons. Sketchpad itself is able to move parts of the drawing around to meet new conditions which suhterland user may apply to them. 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.
