Notable Moments in Mouse History

 

1963: Bill English constructs first mouse prototype based on Douglas Engelbart’s sketches. This mouse uses two perpendicular wheels attached to analog potentiometers to track movement. The first mouse has only one button, but more are to come.

1968: Douglas Engelbart gives a 90-minute demonstration on December 9 at the Fall Joint Computer Conference in San Francisco. Among other things, it showcases a refined SRI mouse with three buttons.

1972: Jack Hawley and Bill English, inspired by Engelbart’s work, design a digital mouse for Xerox PARC. This new mouse does not require an analog-to-digital converter but instead sends digital positional information directly to the computer. It also contains the first mouse ball, a metal ball bearing pressed against two rollers to track movement. A similar tracking design (albeit with a few drastic modifications), would be used in most mice for the next 27 years.
