Acceleration Sensor Useage -> A simple, uncalibrated estimation of the devices acceleration.
Linear Acceleration Sensor Useage -> A simple estimation of the devices linear acceleration provided by Android.
Low Pass Linear Acceleration Sensor Useage -> A simple estimation of the devices linear acceleration based on a low-pass filter.
Complementary Linear Acceleratoin Sensor Useage -> A calibrated, sensor fusion backed estimation of the devices orientation. Uses a complementary filter in conjunction with the acceleration, magnetic and gyroscope sensors.
Kalman Linear Acceleration Sensor Useage -> A calibrated, sensor fusion backed estimation of the devices orientation. Uses a Kalman filter in conjunction with the acceleration, magnetic and gyroscope sensors.
