Assume that you can take a "virtual camera"
You seem to be looking for a way to get a real-world position and orientation, which can be used to position/orient a virtual camera within your virtual world. Is that the idea? It seems reasonable possible. Usually this would be done with software using sliders and so on within an application, but I'm sure it would be possible to create a six degree of freedom input device if you really wanted to. I don't imagine it would be easy to get it to work well enough to be useful in practice, but it would certainly be possible.
