Door Transition Detection for Long-Term Stability in Pedestrian Indoor Positioning

Jackermeier, Robert ; Ludwig, Bernd



Abstract

Many smartphone-based indoor positioning systems rely on pedestrian dead reckoning for fine-grained position tracking. In this paper, we show how one of its major shortcomings - the accumulation of errors over time - can be effectively overcome in a navigation setting by detecting door transitions along the route. Using only the sensors included in a handheld smartphone and different on-device ...
