Height Difference Determination Using Smartphones Based Accelerometers

Indoor navigation based on Pedestrian Dead Reckoning (PDR) is a highly researched topic in recent years. PDR is a two-dimensional dead reckoning technique that employs inertial sensors, such as those available in smartphones, to provide the user’s position. If the vertical position component is also required, it can be obtained from the smartphones’ barometer. However, unlike accelerometers, appro...
