Acceleration Explorer

Acceleration Explorer is an open source Android application with two different purposes. The first purpose is to provide examples to developers of how to implement the Android acceleration sensor and apply various smoothing and linear acceleration filters. The second purpose is a functioning application allowing teachers, students and hobbyists (who may not be interested in the code) to visualize the acceleration sensor's outputs and how different filters effect the outputs. The source code is available on GitHub, here: https://github.com/KEOpenSource/AccelerationExplorer

Acceleration Explorer has five main Activities. A logger view, a vector view, a tilt view, a noise view and a diagnostic view. Each Activity provides a different visualization of some aspect of the acceleration sensor.

Acceleration Explorer Features:

* Plots the output of all of the sensors axes in real-time
* Log the output of all of the sensors axes to a .CSV file
* Visualize the magnitude and direction of the acceleration as a vector
* Smoothing filters include low-pass, mean and median filters
* Easily compare the performance of smoothing filters
* Linear acceleration filters include low-pass as well as sensor fusion complimentary (orientation, rotation matrix and quaternion) and Kalman (quaternion) filters
* Visualize the tilt of the device
* Measure the acceleration sensors frequency, offset and noise
* Compare the performance of multiple devices
