The quaternion read-only property of the OrientationSensor interface returns a four element Array whose elements contain the components of the unit quaternion representing the device's orientation.

If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See Feature-Policy for implementation instructions.


var quaternion = orientationInstance.quaternion
