Pedestrian Dead Reckoning With Wearable Sensors: A Systematic Review [PDF]
IEEE Sensors Journal, 2021 Pedestrian Dead Reckoning (PDR) is the process of calculating one's current location by using the previously known position, and advancing that position over time using established or estimated speeds and trajectories (or alternatively stride lengths and directions). PDR plays an important role in modern life, including tracking locations of people and
