ERDC DECEL Mobile App

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.
