On attitude estimation with smartphones [PDF]

open access: yes2017 IEEE International Conference on Pervasive Computing and Communications (PerCom), 2017
We investigate the precision of attitude estimation algorithms in the particular context of pedestrian navigation with commodity smartphones and their inertial/magnetic sensors. We report on an extensive comparison and experimental analysis of existing algorithms. We focus on typical motions of smartphones when carried by pedestrians.
