Under what title was Douglas Engelbart's computer mouse design patented?
Show answer
X-Y Position Indicator for a Display System
Douglas Engelbart's 1970 patent described a wooden shell with two perpendicular wheels used to track movement on a flat surface. It earned the nickname 'mouse' because the connecting cord resembled a tail, a term that eventually became more famous than its formal technical title. Despite its massive impact, Engelbart never received royalties for the invention because the patent expired just before the personal computer revolution began.
