Documents are children of POIs, but are treated similarly to POIs. All voice commands which are available for documents are detailed above.
If a POI has document children, the user may view the expanded list (carousel) of document previews by using "Show Documents". The carousel can be navigated using "Next" and "Previous", or by tapping on the individual previews. The documents can then be placed anywhere in the world by tapping the centered preview, and tapping again to release the document (while it loads).
==== Scaling documents ====
The user can scale flat (images and pdfs) and 3D objects once they are placed. For flat documents, the handle in the top right corner must be tapped, while holding down the tap gesture. Then, simply move your hand in any direction to start scaling the document up or down. Release the handle to stop scaling.
3D documents can be scaled similarly. The only difference is that there is no handle. The user can simply tap and drag anywhere on the visible mesh to scale the object.
