⭐ Core Definition: Mother of All Demos

"The Mother of All Demos" was a landmark computer demonstration, named retroactively, of developments by Stanford Research Institute's Augmentation Research Center. It was presented at the Association for Computing Machinery / Institute of Electrical and Electronics Engineers (ACM/IEEE)—Computer Society's Fall Joint Computer Conference in San Francisco, by Douglas Engelbart, on December 9, 1968.

The 90-minute live demonstration featured the introduction of a complete computer hardware and software system called the oN-Line System or, more commonly, NLS, which demonstrated for the first time many of the fundamental elements of modern personal computing, including windows, hypertext, graphics, efficient navigation and command input, video conferencing, the computer mouse, word processing, dynamic file linking, revision control, and a collaborative real-time editor.

Mother of All Demos in the context of Computer mouse

A computer mouse (plural mice; also mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer.

The first public demonstration of a mouse controlling a computer system was done by Douglas Engelbart in 1968 as part of the Mother of All Demos. Mice originally used two separate wheels to directly track movement across a surface: one in the x-dimension and one in the Y. Later, the standard design shifted to use a ball rolling on a surface to detect motion, in turn connected to internal rollers. Most modern mice use optical movement detection with no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system.
