Changing the shape of the viewscreen would certainly help. (Maybe add the famous scrolling blinky lights to the bottom of it as well?)
Add some directional signage to the wall panels if possible. The TMP peel off graphics book is a good source of these. I think the people making the 2009 movie had a copy. ;)

Change the color of the glowy turbolift tubes too...
