The Holo Tile Floor

Very recently in the news was an invention called the Holo Tile Floor created by Disney's National Inventors Hall of Fame member Lanny Smoot. This creation allows the user to "walk" in any direction without moving anywhere! The floor shifts to compensate for the user's leg action so that the user doesn't actually move anywhere - something like a multidirectional running machine. Not only that but it can do this for multiple users on the same Holo Tile floor simultaneously, each moving in their own direction! What really captivated my interest was I had tried to design such a device myself a few years back. I was inspired by the VR action modules e.g. running, climbing etc. Needless to say I could not figure out how such a device could be designed. Now that I read about it I am very intrigued by the technicalities of the design. Now presumably one could go look at the patent for the technical details. I was wondering however if any of you know of a more "user friendly" but still technical description of how this floor works? Please let me know.
