Open post Chris Engelbert / noctarius @noctarius2k@mastodon.online · 46mo ago Replying to @ole@chaos.social <p>I recently learned that German company Telefunken arguably invented the computer mouse. They offered a “Rollkugelsteuerung” (“rolling ball control”) for one of their mainframes in 1968, months before Douglas Engelbart’s “mother of all demos”. Telefunken’s mouse was also more advanced than Engelbart’s mouse as it used a ball instead of two wheels.
