Acceleration from device's coordinate system into absolute coordinate system

http://stackoverflow.com/questions/11578636/acceleration-from-devices-coordinate-system-into-absolute-coordinate-system

sensors values as parameters use android.opengl.Matrix.invertM on the rotation matrix to invert it not transpose use Sensor.TYPE_LINEAR_ACCELERATION sensor to get linear acceleration vector in device's coord. sys. use android.opengl.Matrix.multiplyMV to multiply the rotation..

Android Accelerometer Profiling

http://stackoverflow.com/questions/16392142/android-accelerometer-profiling

I'd make the following observations In addition to Sensor.TYPE_ACCELEROMETER Android also has Sensor.TYPE_GRAVITY and Sensor.TYPE_LINEAR_ACCELERATION . If you log the values of all three then you notice that the values of TYPE_ACCELEROMETER are always equal to the sum of..

how to calculate phone's movement in the vertical direction from rest?

http://stackoverflow.com/questions/6291110/how-to-calculate-phones-movement-in-the-vertical-direction-from-rest

and that is a different story. The linear acceleration is available after sensor fusion as described in the video. See Sensor.TYPE_LINEAR_ACCELERATION at SensorEvent . I would first try a high pass filter to detect sudden increase in the linear acceleration along the vertical..

Android TYPE_LINEAR_ACCELERATION sensor - what does it show?

http://stackoverflow.com/questions/7858759/android-type-linear-acceleration-sensor-what-does-it-show

n I bind listener with following parameters mSensorManager.registerListener linAcc mSensorManager.getDefaultSensor Sensor.TYPE_LINEAR_ACCELERATION SensorManager.SENSOR_DELAY_GAME It works OK but when i analyze data dump calculating speed like V V0 AT where V0 0 at first.. and using same formula to calculate speed i get good results much close to reality. So the question is what Sensor.TYPE_LINEAR_ACCELERATION really shows Where am I wrong or something is wrong with Sensor.TYPE_LINEAR_ACCELERATION realization I use Samsung Nexus.. So the question is what Sensor.TYPE_LINEAR_ACCELERATION really shows Where am I wrong or something is wrong with Sensor.TYPE_LINEAR_ACCELERATION realization I use Samsung Nexus S phone android accelerometer sensor share improve this question Very interesting question..
