Actually this would help ameliorate the big problem that all 1st person console games seem to have where the default FOV is always something ridiculously low like 60'
"The user places the projector device on their coffee table."
Because all living rooms are built with the same land-use considerations as Seattle, and thus have plenty of room for the FOV cone of the projector/camera system!
There are no dense urban populations that have constrained living quarters. There are no small homes.
Also, what the everloving fuck is the point of watching video where there's a tiny clear window into a huge blurry mess? It's almost as though this concept were designed by engineers with no conceptual knowledge of art.
