This project reveals that each smartphone accelerometer responds differently to the same motion stimulus. We explore the idiosyncrasies of the accelerometers to fingerprint the smartphones.

This project shows that the location of screen taps on modern smartphones and tablets can be identified from accelerometer and gyroscope readings. Our findings point to a potential security issue.
We present a phone based sensing system to determine if a user in a moving vehicle is a driver or a passenger. We foresee several useful applications for this technology including tracking the reckless driving behavior.
We envision a system called PhonePoint Pen that uses the in-built accelerometer in mobile phones to recognize human writing. By holding the phone like a pen, a user should be able to write short messages or draw simple diagrams in the air.
