This is a pretty damn smart idea that will probably spawn a number of new technologies to improve HCI. The general idea that you can get more information from a data stream by filtering out some of the data is not a new one to those familiar with information theory (in the Shannon sense), but to apply it to something like the movements of a mouse is a new idea to me. And, ya know, if it’s new to me, then… OK, that doesn’t really mean it’s new to anyone else.
