This problem could be avoided by designing the machines to be as visually <i>simple</i> as possible. Remove all unnecessary features and homogenize what remains. This would have the incidental perk of making them look much better.<p>If this isn't enough, a photo of the machine could be shown on the screen and the user asked to verify that the real thing looks identical.

Hmmm. I didn't wait for it to load. <-- See that? That's my initial comment, then I thought better of it, came back and waited for the thing to load; and I'm glad I did. It was a very informative and fast read. It should be made into a web site. PDFs drive me nuts.
