The increasing development and proliferation of mobile devices as smartphones and tablets opens up the demand of a range of services related to the geographic position of the user. Location-based services may affect several aspects in everyday life: from entertainment to health, from marketing to emergency in public buildings. One application of interest to a wide range of audience is represented by indoor navigation systems: museums, shopping malls, hospitals, university campus and other places are potential parties to develop navigation systems to support the use of their services. However, GPS signal is not always available in indoor locations and that makes the research for alternative systems working in the absence of signal important.
Roodin is an indoor pedestrian navigation system that works without GPS signal using normal smartphone equipment: accelerometer, compass, camera and an Internet connection. The system exploits movement sensors available in common smartphones to individuate a user position in an indoor environment.

no need for expensive additional infrastructure.
Any commercial activity or public space as shopping malls, museums, schools, campus, hospitals that want to supply their users an indoor navigation system (linked to points of interest). Furthermore, the service has a clear potential for what concerns the security provisions, ensuring a functional system even in case of emergency.
