While we’ve pretty much got to the point where we take GPS-enabled navigation systems for granted, there’s one rather prominent place where they can’t access the necessary satellites – indoors. A number of projects have taken on the challenge of indoor navigation, incorporating things like accelerometers, “invisible” landmarks, rapidly flickering lights, and magnetic fields. The experimental new NAVVIS system, however, utilizes a database of photographs.
