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)
