Researches on inertial navigation systems (INS) have formulated complex step detection algorithms and stride length estimations. But for current systems to work, INSs have to correctly identify negative pedestrian locomotion. Negative pedestrian locomotion are movements that a user can naturally make without any real position displacement, but has sensor(More)
GPS as a localization system performs poorly indoors. Other methods were developed for indoor navigation, many of which required external infrastructure making them location and environment dependent. One approach that does not require external infrastructure is dead reckoning. Given users with smartphones, dead reckoning helps users find their way by(More)
