Computer mouse co-inventor William English dies at 91:
One of the pioneers of the modern computer interface has passed away: the New York Times reports that William "Bill" English died on July 26th from respiratory failure at the age of 91. Alongside Douglas Englebart at the Stanford Research Institute, English helped develop the first computer mouse and put together a 1968 "Mother of All Demos" that outlined many concepts that would come to PCs over the decades, such as graphical user interfaces, online text editing, video calls and hypertext links.

Boomer engineer says: the ball was a convenient way to transfer motion up to two axles that spun encoder wheels. So even mice with a ball, still had "two wheels", just hidden inside. Because of the size ratio (gear ratio) between ball and axles, the encoders spun faster than the ball. In turn this meant that the encoder wheels could have fewer&larger slots so the optical detectors weren't so critical.
