The Fascinating History of the First Computer Mouse

The computer mouse was invented by Douglas Engelbart, a researcher at the Stanford Research Institute (SRI, now SRI International) in Menlo Park, California.

Engelbart began developing the idea in the early 1960s as part of a larger project he started in 1962 aimed at using computers to 'augment human intellect.'

The first mouse prototype was a hand-carved wooden shell with a single button and two perpendicular metal wheels inside that tracked movement along the X and Y axes.

Engelbart's formal name for the device was the 'X-Y Position Indicator for a Display System.'

The device was nicknamed the 'mouse' because its cord trailed out the back like a tail, and the name stuck.

Bill English, an engineer at SRI, built the first working mouse prototype from Engelbart's design.

Engelbart publicly unveiled the mouse on December 9, 1968, during a 90-minute presentation at the Fall Joint Computer Conference in San Francisco, an event later nicknamed 'The Mother of All Demos.'

That same 1968 demo also introduced hypertext, video conferencing, and collaborative real-time editing, ideas that were decades ahead of their time.

Engelbart and SRI were granted U.S. Patent No. 3,541,541 for the 'X-Y Position Indicator for a Display System' on November 17, 1970.

The patent application had actually been filed years earlier, in 1967, before the public demo took place.

Engelbart never earned significant royalties from the mouse patent; SRI licensed the technology to Apple in the 1980s for a flat fee.

One of the first commercial computers designed to work with a mouse was the Xerox Alto, developed at Xerox PARC in 1973.

Apple popularized the mouse for home users with the Apple Lisa in 1983 and the Macintosh in 1984, both of which used a single-button design inspired by earlier research.

Early mice used mechanical wheels or a rolling ball to track movement; modern mice typically use an optical or laser sensor instead.

Wireless mice, which use radio or Bluetooth signals instead of a cord, became widely available in the late 1990s and 2000s.

Today's mice come in many specialized forms, including ergonomic mice designed to reduce wrist strain and gaming mice with programmable buttons and high-precision sensors.

The original wooden prototype mouse still exists and has been preserved and exhibited by institutions including the Smithsonian.

Engelbart received the National Medal of Technology in 2000 and was inducted into the National Inventors Hall of Fame for his work on human-computer interaction.
