The drift, if you are moving a mouse on a desk its a very localized, temporary movement difference you have to track - the moment you try to scale this up you'll amplify inaccuracies a lot. Also if you pick up a mouse and place it at a different spot on a surface, the mouse won't be able to register what happened. Whereas this research project actually accomplishes that, you place your camera anywhere on a previously scanned/mapped surface, the software will instantaneously tell where you are. So the difference: a mouse only tracks movement by relative changes. This project maps a texture onto a globally known map and calculates an absolute location.
