Where Did Your Mouse Come From?

Many readers will be familiar with Douglas Englebart’s 1968 so-called “Mother of All Demos”, in which he described many of the devices and technologies we would be using two or …. Where Did Your Mouse Come From. Among these was a primitive computer mouse, but while famous it was by no means the earliest pointing device.

At the recent Vintage Computer Festival Berlin, [Dmitriy Kostiuk] delivered a fascinating lecture of the history of the pointing device. It’s a long video that we’ve placed below, and it’s an exhaustive examination of the topic from the earliest examples to the 1990s when mice became commoditized. It’s a surprise to find that the first pointing device was a trackball built for a 1950s Canadian warship, with a surprisingly modern-looking optical encoder.

Englebart’s 1966 wooden block with its pair of wheels and potentiometers had a less-well-known and much more stylish competitor in the same year from Telefunken. We visit the various design iterations as the form of what we’d call a mouse today took shape. It’s unexpected to find that those Sun mice with the spotty mouse pad weren’t from Sun at all, they were from Mouse Systems.
