You can't see more, you actually see less (Score 1)

A projector doesn't project pixels that would be offscreen on a normal monitor. Therefore all you are doing is stretching the pixels near the edges around you and moving them even further outside your peripheral vision. Hence, you see less. Good concept, stupid implementation. The concept however requires the 3d world to render the portions outside the normal view and maybe have a few projectors to project it around you to get a true 180 FOV.
