I'm sorry if I'm being confusing-I'll try to be more clear.
What I am trying to do is create a different type of computer, a type of computer that is not yet in game. Yes, this Aera computer is an upgrade computer (for capships). However, since (in this case) you are flying a capship, it would also handle trade (and possibly other not-yet thought of things). My intention was that we could create a computer that would NOT change the room you are in, but project (in this case) a semi-transparent "hologram" in front of you, with you staying in the SAME ROOM.
Personally, it makes no sense to me that you would conduct trade in a big ship the same as you would in a small ship. A decent example would be if you went to a store to buy food in a small car, vs going in an 18-whealer. You wouldn't park the same, you wouldn't talk to the same people, etc. I think that the destination between a capship and a regular ship should be greater. This computer is just a visual distinction between the capships and the regular ships.
The illustration attached to the first post is of the BACKGROUND, that the hologram is projected over. (The background is things like walls, windows, landscapes, etc. Basically, the room the holo projector is in.) The hologram effect can be a shimmery, semitransparent field with text and icons in it. If you click a button, the hologram changes-perhaps it wipes clear, and then brings up the new text/images.
One thing I would like to have these new computers do is to have a more aesthetically pleasing GUI. The pictures should be larger (and better quality), the text is nicer, the SFX are better (or at least present, as there are no SFX right now).
Does it make more sense now? The picture is of the ROOM that the GUI of the computer is in. The computer's GUI is a hologram projected into the room by greebles in the room (the computer is somewhere else, so, for all intents and purposes, the computer's GUI is the computer). You don't have to change rooms every time you buy something, you simply click on the "computer."
