Magnetic Field Feature Analysis of Smartphone Application Activities Using Android MI Sensors [Report]

NESL Technical Report #: 2013-3-1


Abstract: In this project, the magnetic field data of three axes are read by the magnetometer in an Android Smartphone and are recorded by an application then processed through MATLAB. Various denoising techniques and frequency domain analysis is implemented and two sets of experiment are designed by varying the direction, the phone activity, and the distance. The first experiment is done in order to analyze the magnetic field feature generated by another smartphone, whereas the second experiment is to monitor the change of the magnetic field due to different activities running on the same phone. WiFi transmitting and music-playing activities are chosen for the test, and different characteristics of magnetic field features are discovered respectively.
