agreed, however I hear they shut down the future warrior project (or land warrior). Was interesting but the system over all was pretty broken from what I read and saw. But never got to play with it.
I guess to how broadly would you define AR? As fighter pilots could have been using HUDs projected onto glass for years. I would kinda say thats super alpha stage and that multi-million dollar helmet for the joint strike fight was more of an AR setup in the context that I am taking about.
however I used VR for "training". I thought it was dumb, I liked the projected method more, it was like a arcade shooter but still more believable that the VR set up we used
