Knee Pointing Device May 6, 2006Posted by reto wettach in innovative interfaces, physical interaction design.
Douglas Engelbart, the "Father of the Mouse", was – before inventing the mouse – also lookinhg at alternative methods for controlling a pointing device. Amongst others, he was looking at the knee. In an interview, Doug says about this idea:
"That device was based on my observation that the human foot was a pretty sensitive controller of the gas pedal in cars. With a little work, we discovered that the knee offered even better control at slight movements in all directions. In tests, it outperformed the mouse by a small margin."
