Computer Mouse

A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface and is used to control graphical user interfaces. Douglas Engelbart of the Stanford Research Institute first recorded the concept on November 14, 1963, and Bill English helped build a working prototype in 1964; the device was first mentioned in print in a 1965 report and publicly demonstrated on December 9, 1968, at what became known as The Mother of All Demos. The mouse remained a niche tool until the 1984 Apple Macintosh and the 1985 Amiga and Atari ST brought it into mainstream personal computing, and it has since evolved from a mechanical ball design to optical and laser variants and from wired to wireless connections.
