\subsection{Barometer}
used if available
relative positioning (z)
relative to the first few measurements
also used to determine uncertainty

\subsection{Transition}
a graph based on the building's floorplan
uses prior knowledge (floorplan + desired destination [if known])
uses random-walks to perform the transition
uses imo (acc,gyro) for the random-walk (distance/direction)
calculated offline

\subsection{Step- and Turn-Detection}
used for the transition step
uses the smartphone's imu (acc, gyro)
simple step detection using magnitudes
simple turn detection by integrating over the gyro
feeds the transition

\subsection{\docWIFI}
absolute positioning using wifi (x,y,z)
no fingerprinting
uses signal-strength prediction model
position of access points must be known beforehand
only 2 parameters for all APs
only vague position estimation
\subsection{\docIBeacon{}s}
optional
same as wifi
but only one param: as txp is broadcasted
