Finally, the mystery is solved. Whenever in your youth you saw a cartoon animal running without moving, this is what they were standing on.
On a more serious note, the tech looks interesting, but unfortunately the article doesn’t explain at all how it works. I think the discs are rotating so as to make you slide back onto the original position?
Imagine a disc spinning clockwise, the top edge is moving to the right, the bottom is moving to the left, and the right edge is moving down and the left edge is moving up.
By mounting that disc at an angle and changing which edge makes contact with whatever rests on it (your foot in this case), you can change the direction the disc's rotation moves it.

Found the patent. Will have a read later.
