<p>Gyroscope sensor</p>
<p>The gyroscope returns the current rate of rotation in radians per second. The rotation is positive in the counter-clockwise direction. That is, an observer looking from a positive location on one of the axes would see positive rotation on that axis when it appeared to be rotating counter-clockwise.</p>
<p>values[0]: Angular speed around the x axis values[1]: Angular speed around the y axis values[2]: Angular speed around the z axis</p>
<p>For phones held in portrait mode, the axes are defined as follows: -X ... +X : left ... right -Y ... +Y : bottom ... top -Z ... +Z : farther ... closer</p>
<p>The axis data is not changed when the phone is rotated.</p>
