This is a complete guess, but maybe you could do it through scripting, but guess it depends on how the camera is suppose to work.

I looked at the page you linked and have to admit that I know nothing about this technology, but I got a weird feeling straight away, that something seems a bit off. I watch the trailer and it shows nothing, the only thing you see are peoples reaction to something that they see on the screen. Which obviously got me more interested to find out why exactly their main trailer doesn't show anything. So looked further and finally found another video on their site showing what they are talking about and my guess for why they don't show what people is seeing on the camera in the trailer, is most likely because its not really that amazing, Maybe you have to see what it looks like in reality, but to me, it seems more like some people desperately trying to sell a product by saying that its over the top amazingly good and trying to convince people that its the case, when it ain't. :)

This is the video im talking about where he shows all the cool stuff. Try to compare that with those people in the trailers reaction. Something doesn't really add up I think.
