Abstract
A mobile device () carried by a user has sensors providing acceleration and orientation information. These are processed to provide trajectory for the device. The processing includes improved methods using different modules () for classifying the motion () and detecting a user's steps (), tracking the orientation () and acceleration () of the device (), estimating the length of the user's steps () and estimating the heading () of the user. The trajectories are compared to a map and corrected by the constraints provided by the map. Parameters of the methods of producing the trajectories are optimised on the basis of maximising probability of the trajectory found by the map matching given the indicated trajectory.
