Abstract
The proliferation of powerful mobile devices, along with the increasing demand of location information, has driven the researches to develop positioning applications with higher accuracy. In this paper, we build an Android application which achieved the aim of seamless positioning between the inside and the outside. The system contains four parts: outdoor positioning, which uses GPS and Baidu Map, indoor positioning, which adopts Wi-Fi fingerprint positioning, contextual detection, including indoor and outdoor detection and floor detection, which takes advantage of multiple sensors integrated on Android, functional configuration, whose work is to establish and manage Wi-Fi fingerprint database. We developed an Android APP that runs on the smartphones and experiments have been carried out in real environment with good accuracy of output. Experimental results indicate a remarkable performance improvement by using the proposed method about HMM.
