A rapid-prototyping platform for PDR-based indoor positioning system on smart phones

Pedestrian Dead Reckoning (PDR) is a popular indoor positioning mechanism that requires minimal infrastructure. Meanwhile, smart phone is becoming popular in recent years, making it an ideal sensor platform for indoor positioning. Nevertheless, realizing PDR on a smart phone is still challenging as the developer has to go through several construct/ evaluate cycles before finding appropriate algorithms and parameters. In this paper, we propose a flexible platform for rapid-prototyping PDR indoor positioning engine on smart phones. Based on the platform, the developer is able to tailor the engine by the composition of components so that the construct/evaluate cycle time can be greatly reduced. A case study and experiments are also presented to explain how the proposed platform assists developers to improve accuracy overtime.
