Pedestrian Dead Reckoning for Multiple Walking Styles Using Classifier-Based Step Detection
IEEE Journal of Indoor and Seamless Positioning and Navigation, 2023 Traditional pedestrian dead reckoning (PDR) systems have been designed for scenarios where users walk straight ahead. However, user behavior observation at the museum revealed that users often stop or walk sideways to look at the exhibits.

Floor Number Detection for Smartphone-based Pedestrian Dead Reckoning Applications
2021 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2021 We present a new floor number detection algorithm for use in smartphone-based indoor localisation systems. It is designed to complement any pedestrian dead reckoning (PDR) algorithm able to detect steps and estimate a 2D trajectory from data of the smartphone’s inertial measurement unit.Our proposed method is based on the Viterbi algorithm, fusing data

Probabilistic Context-Aware Step Length Estimation for Pedestrian Dead Reckoning [PDF]
IEEE Sensors Journal, 2018 This paper introduces a weighted context-based step length estimation algorithm for pedestrian dead reckoning. Six pedestrian contexts are considered: stationary, walking, walking sideways, climbing and descending stairs, and running. Instead of computing the step length based on a single context, the step lengths computed for different contexts are ...

Pedestrian Dead Reckoning with Particle Filter for handheld smartphone
2016 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2016 Commonly used Global Navigation Satellite Systems (GNSS) are inappropriate as Location Based Services (LBS) in indoor environment. Therefore research teams are developing different systems, which can be used as a suitable alternative. One of options is to use Inertial Navigation System (INS) which consists of inertial sensors and mathematic procedures.
