Question 2: Douglas Engelbart's first computer mouse prototype in 1964 had one button
From the Doug Englebart Insitute:
Doug Engelbart invented the computer mouse in the early 1960s in his research lab at Stanford Research Institute (now SRI International). The first prototype – a one-button mouse in a wooden shell on wheels – was built in 1964 to test the concept.
Based on results of his landmark study on 'Augmenting the Human Intellect,' Engelbart had received modest funding to evaluate the speed and efficiency of various devices for pointing on a display screen, like the joy stick, including a few his team rigged up and threw into the mix, like the one they called a "mouse." Which pointing device scored the highest? How was it built and tested? What inspired all this anyway? Read on! And don't miss Check it Out below for original footage, photos, timelines, documents, fun facts, and more.
A patent application for the mouse was filed in 1967, and US Patent 3,541,541 was awarded in 1970 under the descriptive title "X-Y position indicator for a display system."
Although many impressive innovations for interacting with computers have followed in the last 50 years since its invention, the mouse remains to this day the most efficient hands on pointing device available for speed and accuracy.
So why does it now have 3 buttons
