I have read here:
http://stackoverflow.com/questions/...ccelerometer-readings-in-android-3-axis-accel
http://developer.android.com/reference/android/hardware/SensorEvent.html
Both links to use low pass filter by taking alpha = 0.1 or 0.2
1. But that does not make any sense to me. How it would remove gravity component?
2. Is it right method?
3. How to select it is 0.1 or 0.2?
