Android Question orientation of the phone imu style for head tracking

[Victor jung]

Hello,
As developing a google cardboard app, i am trying to track the head position in the space, head pan tilt.
I tried with the TYPE_ORIENTATION sensor, but all the axis, moves when moving only one angle... any ideas what TYPE_ORIENTATION sensor actually measures?
Also how should I code that?
I read this: http://developer.android.com/reference/android/hardware/SensorManager.html#getOrientation(float[], float[])

But still I am not sure what it does measure, and, how to use this function... not in phone sensor library I guess...

This simple example is useful to understand how the values change when you move the phone. You should probably use the accelerometer instead.

thanks for your reply, this is already the example I used.
The accelerometer is good fo static position measuring, but during the moves, values are wrong because of head aceleration. Normally I should use, a combination of accelerometer gyroscope and magnetometer, but I think orientation sensor does this already, just dont understand wich values it gives...
