In Mobile Emergency Pro, the in/out detector takes a decision on the basis of the: GPS accuracy, previous position (if any), and in the case of uncertainty ask to the user to get the point acquiring a QR code. Once the position is identified, the corresponding map is shown to the user (taking from the cache or downloaded) and the user may navigate in the context. The distance between the last GPS position (that should be just out of the door) and the QR coded position should be coherent. In any case, the QR coded position is taken as a reference, but a confirmation may be requested to the user in some cases. If the building is correct, and floor has to be changed the system provides direction to the closest stairs showing them on the map. Once reached the correct floor, the navigator displays a map showing the current position of the user and the location of the target position. In both cases, the indoor path manager helps the user to easily get closer and reach the destination.
