Abstract
In this paper, we describe a prototype of an adaptive indoor navigation system
which is based on mobile devices and navigates visually impaired people through
an unknown building. The system determines the users position inside the building on
the basis of a map of the building with the help of Bluetooth-beacons. Since an exact
navigation is necessary for navigating visually impaired people, we show how the
system uses landmarks for gaining a higher precision for the navigation instructions
for the users. We show how the system is able to determine the maximal achievable
accuracy in localizing users in the given infrastructure and how the system adapts the
navigation to the accuracy.
