       * <p><u>Definition of the coordinate system used below.</u><p>
       * <p>The X axis refers to the screen's horizontal axis
       * (the small edge in portrait mode, the long edge in landscape mode) and
       * points to the right.
       * <p>The Y axis refers to the screen's vertical axis and points towards
       * the top of the screen (the origin is in the lower-left corner).
       * <p>The Z axis points toward the sky when the device is lying on its back
       * on a table.
       * <p> <b>IMPORTANT NOTE:</b> The axis <b><u>are swapped</u></b> when the
       * device's screen orientation changes. To access the unswapped values,
       * use indices 3, 4 and 5 in values[].
       *
       * <p>{@link android.hardware.SensorManager#SENSOR_ORIENTATION SENSOR_ORIENTATION},
       * {@link android.hardware.SensorManager#SENSOR_ORIENTATION_RAW SENSOR_ORIENTATION_RAW}:<p>
       *  All values are angles in degrees.
       *
       * <p>values[0]: Azimuth, rotation around the Z axis (0<=azimuth<360).
       * 0 = North, 90 = East, 180 = South, 270 = West
       *
       * <p>values[1]: Pitch, rotation around X axis (-180<=pitch<=180), with positive
       * values when the z-axis moves toward the y-axis.
       *
       * <p>values[2]: Roll, rotation around Y axis (-90<=roll<=90), with positive values
       * when the z-axis moves toward the x-axis.
       *
       * <p>Note that this definition of yaw, pitch and roll is different from the
       * traditional definition used in aviation where the X axis is along the long
       * side of the plane (tail to nose).
       *
       * <p>{@link android.hardware.SensorManager#SENSOR_ACCELEROMETER SENSOR_ACCELEROMETER}:<p>
       *  All values are in SI units (m/s^2) and measure contact forces.
       *
       *  <p>values[0]: force applied by the device on the x-axis
       *  <p>values[1]: force applied by the device on the y-axis
       *  <p>values[2]: force applied by the device on the z-axis
       *
       *  <p><u>Examples</u>:
       *    <li>When the device is pushed on its left side toward the right, the
       *    x acceleration value is negative (the device applies a reaction force
       *    to the push toward the left)</li>
       *
       *    <li>When the device lies flat on a table, the acceleration value is
       *    {@link android.hardware.SensorManager#STANDARD_GRAVITY -STANDARD_GRAVITY},
       *    which correspond to the force the device applies on the table in reaction
       *    to gravity.</li>
       *
       * <p>{@link android.hardware.SensorManager#SENSOR_MAGNETIC_FIELD SENSOR_MAGNETIC_FIELD}:<p>
       *  All values are in micro-Tesla (uT) and measure the ambient magnetic
       *  field in the X, Y and -Z axis.
       *  <p><b><u>Note:</u></b> the magnetic field's Z axis is inverted.
       *
