Detailed Description

The QAccelerometerReading class reports on linear acceleration along the X, Y and Z axes.

The accelerometer returns acceleration values along 3 axes. The scale of the values is meters per second squared. The axes are arranged as follows.

             +z
              |
              |      +y
              |     /

    |_________!/

A monoblock device sitting at rest, face up on a desk will experience a force of approximately 9.8 on the Z axis (ie. towards the roof). This is the proper acceleration the device experiences relative to freefall.
