[Cyborg] indoor positioning system using magnetometer

It's hard for me to believe that the magnetic field at each location
would be globally unique - at least at that resolution. Seems more
likely that you have to give the app a rough location (e.g. this
building, or here's a nearby wifi/cell tower location...) and from there
it can pin-point you.
Also, anyone else notice the curious total fixity of the cell phone
angle and location with respect to the camera & floor? They must have
had some kind of fancy rig to hold them that rigidly. Maybe some smoke
& mirrors? It also makes me wonder how well the indoor positioning app
works if the phone tilts, or shakes...
Still, really cool technology. I imagine it would be super useful for
things like google glass :-)
