The invention of the computer mouse
Originally created in 1964, the computer mouse has evolved through several iterations, from a mechanical device using balls and wheels to optical and laser-guides interfaces, from corded to wireless. But the constantly-changing world of personal devices may one day make these handy tools obsolete.

The trackball became a key component of a mechanical computer mouse.

"It was no great shakes, the invention," Engelbart said. "It was just putting things together that were already known."
Clicking once on the mouse button selected a word on the screen by placing an arrow underneath it; a second click would execute a delete command.
"I don't know why we call it a mouse, sometimes I apologize," Engelbert admitted during the demonstration. "It started that way and we never did change it."
The ball mouse supplied with Alto used light-reading sensors to detect the directional movement of the trackball.
In a review published by the San Francisco Examiner, John Dvorak wrote, "The Macintosh uses an experimental pointing device called a 'mouse'. There is no evidence that people want to use these things."
LEft: Apple CEO Steve Jobs delivers his keynote speech at Macworld on January 9, 2007 in San Francisco, California, during which he introduced the new iPhone. Eschewing a stylus, the iPhone uses a technology Apple calls "multi-touch."
"We're going to use a pointing device that we're all born with," Jobs said.
At least one billion mice (or is it "mouses"?) have been sold worldwide to date. But with changing technology, the future of the mouse is hardly guaranteed.
In January 2013, mouse-maker Logitech announced it was shifting its business to cater more toward the owners of tablets and smartphones.
Engelbart died Tuesday, July 2, 2013, at his California home. He was 88.
