The earliest optical mouse came out in 1980. One of the earliest prototypes was invented by Steve Kirsch at MIT. Another optical pointing device was invented by Richard Lyon. These early devices would play a role in changing the history of the computer mouse.
Invented by Douglas Engelbart in 1963, the mouse is a pointing device that recognizes two-dimensional motion. It is found on just about any computer that has a keyboard and commonly used to navigate graphical interfaces. The mouse did not become popular until 1984 when Apple integrated it into its famous Macintosh computer. Peripherals
