Mobile Information Systems Excercise III

Group:

Max Weber (110068)
Muhammad Raisul Islam (113993)

Upper View:

plots the measured accelerometer data graph
red = X
green = Y
blue = Z
white = magnitude

Lower View:

yellow = the FFT of the magnitude

Upper SeekBar:

modify the sample rate (0 - 100.000)

Lower SeekBar:

modify the FFT window size (2dp to 102dp)

Movement Classification

3 States: Chilling, walking, running (was tested in real live so i get the thresholds ;)
printing of the average and the maximum frequency of the FFT result
to classify the state i used only the average frequency (chilling < 25, 25 < walking < 31, runnung > 31)

Problems

i was not able to show an icon of a little running man on the left side of the notification ;)

Test Environment

HTC One M8
the android emulator (but sensor stuff was simulated)
