On this day in 1968, Douglas Engelbart and William English, of the Stanford Research Institute in Menlo Park (CA, US) introduced a computer pointing device that they dubbed a “mouse” during a press conference held in San Francisco’s Brooks Hall. Mr. Engelbart had earlier (1964) prototypes of the device, and later (17 November 1970) he obtained a patent (# 3,541,541) for an “X-Y Position Indicator for a Display System Computer Mouse.”
The mouse changed things. As noted elsewhere (9 July 2008, 1 February 2008, 4 January 2008, 12 September 2007, 12 March 2007), I suspect that multi-touch screens will change things yet again. I wonder if it will take ~30 years (about as long as it took for the mouse to penetrate into the mainstream via Windows 95 [AKA Mac 88]) for multi-touch to become commonplace.
