Deceleration-based friction assessment tool for smart phones.
This software
records accelerometer and magnetometer data from commercial off the shelf
smartphones and reports peak deceleration in units of %g, where g is the
acceleration of gravity. The ERDC DECEL app may ask for permission to
access the device's internal memory. This access is used to save
acceleration and rotation data to the device at the conclusion of a
deceleration test.
