Steve Jobs did not invent slide-to-lock controller
 

One of the central articles of faith in the Apple reality distortion field has been battered like a Scottish Mars Bar, deep fried and served up to a court by Samsung lawyers.

One of the crucial patents in the court battle between Samsung and Apple is the slide-to-unlock control for the iPhone. Apple insists that it invented the technology.

However a video from a Microsoft researcher could spell curtains for that patent. University of Maryland researcher Catherine Plaisant has a 1991 video, entitled "Touchscreen Toggle Design" which shows off a number of ways to model a touchscreen toggle that users can control.

One of the toggles is an on-off slider that users can control by swiping their finger back and forth, which is exactly the method that Steve Jobs claimed he invented. However at the time, Jobs was the CEO of NeXT and had been disassociated from Apple for a good five years following his mid-80s topple at the hands of CEO John Sculley.
