In this paper a low cost solution for implementing an indoor localization system is proposed. The Android app is based on a background service able to log data retrieved from the 9-Degree of Freedom IMU embedded in a smartphone and to compute the current user position. In particular, an Android application is developed: it is able to track the position of a user in indoor environment using smartphones...
Automatic real-time localization of people inside buildings is a huge challenge. For demanding applications in building services, different sensors (e.g. WLAN, RFID, UWB, or ultrasound) are currently used for the real-time indoor positioning. Most systems are only suitable for specific applications or are used under certain conditions, e.g. additional infrastructures and/or sensory mechanisms are...
The earth's magnetic field needs no transmitter infrastructure and can be measured everywhere. Therefore its use in fingerprinting technology for indoor-positioning and navigation seems to be useful. In this work the magnetic field is used in combination with Wi-Fi and RFID in the fingerprinting approach. The idea is to first calculate an approximate solution with Wi-Fi and then refine it with the...
