The blinders aspect is acceptable as I only am concerned with objects scaling at a distance. So even if its like looking at the world through a window I just want to make sure that the object at X distance appears to be the same scale as an object at X distance. Thank you for your input and I am definately going to be comparing the FOV of the projector to make sure everything works out.
Also any help for ideas of search terms of what I want would be helpful. I'm good with using equations its just been a few years since I've done any physics related to this subject.
