<em>This section is non-normative.</em>

* The specification must provide data that describes the physical orientation in space of the device.
* The specification must provide data that describes the motion in space of the device.
* The specification must allow Web applications to register for changes in the device's orientation.
* The specification must be agnostic to the underlying sources of orientation and motion data.
* The specification must use the existing DOM event framework.
