There are two position variables, which don't provide the data (position_3d_accuracy and position_vertical_speed).
I am not sure if the vertical speed provides some info when user is moving. I tested it only when sitting on the chair.
Also this variables don't work since I started tested it in May. I thought I just don't understand how it should work.
