Douglas Engelbart: The Demo

Ok, so for a little history on computers design. This time about GUI development, and the Demo by Dougals Engelbart on Human Interfaces for computers, back in 1968... this is the first time ever someone uses what later was dubbed as THE MOUSE. Very interesting video to watch. It's over 1hr long, so be patient.



Douglas Englebart completed his degree in electrical engineering in 1948 and settled down in a nice job at the NACA Institute (the forerunner of NASA). However, one day while driving to work he had an epiphany: he realized that his real calling as an engineer was not to work on small projects that might only benefit a few people. Instead, he wanted to work on something that would benefit all of humanity. He recalled Bush's essay and started thinking about ways in which a machine could be built that would augment human intellect. During the war he had worked as a radar operator, so he was able to envision a display system built around cathode ray tubes where the user could build models of information graphically and jump around dynamically to whatever interested them.

Finding someone to fund his wild ideas proved to be a long and difficult task. He received his PhD in 1955, and got a job at the Stanford Research Institute, where he received many patents for miniaturizing computer components. By 1959 he had earned enough recognition to receive funding from the United States Air Force to work on his ideas. In 1962, Douglas published his ideas in a seminal essay entitled "Augmenting Human Intellect." In this paper, Douglas argued that digital computers could provide the quickest method to "increase the capability of a man to approach a complex problem situation, to gain comprehension to suit his particular needs, and to derive solutions to problems." He envisioned the computer not as a replacement for human intellect, but a tool for enhancing it. One of the first hypothetical examples he described for this technology was of an architect designing a building using something similar to modern graphical CAD software.
