I've seen these helmets used in SAO a lot and other animes are adopting the same concept. Technology companies are also absorbing every detail of this idea. Sony has even started to make their own virtual reality helmets where users are teleported into the video game. One Shark Tank inventor has already come up with an invention where you can exactly go into a video game and walk through a beautiful scenery. The technology currently costs 30,000 dollars each. Investors have declined to invest in this product because the product wasn't meant to be made for home use. Otherwise is it possible that technology will leap us as far as to having nerve gears in our own homes.
