Douglas Engelbart, the visionary electrical engineer who invented the computer mouse first.............

World's First Mouse

On December 9, 1968, Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute in Menlo Park, CA, presented a 90-minute live public demonstration of the online system, NLS, they had been working on since 1962. The public presentation was a session of the Fall Joint Computer Conference held at the Convention Center in San Francisco, and it was attended by about 1,000 computer professionals. This was the public debut of the computer mouse. But the mouse was only one of many innovations demonstrated that day, including hypertext, object addressing and dynamic file linking, as well as shared-screen collaboration involving two persons at different sites communicating over a network with audio and video interface.
In the patent application, the device was described in technical terms: “An X-Y position indicator control for movement by the hand over any surface to move a cursor over the display on a cathode ray tube, the indicator control generating signals indicating its position to cause a cursor to be displayed on the tube at the corresponding position.”
He had devised the palm-sized, wheel-based instrument in 1963 as a way to move a computer-screen cursor by means other than arrows on a keyboard. Other alternatives being weighed at the time were a light-pen pointed at the screen, a tracking ball and a joystick.
