You can resize the window and place it wherever you like in the AR hud, personally I would size it down and put it on the far left or right of the visual area. Any area you want to use constantly you will want to black out so it works perfect in day or night. the phone is a pretty good example as you can see your texts, call, music and navigation all in one place.
