Full Dive Virtual Reality concept
To be able to achieve a Full Dive I feel a system similar to that of the anime Sword Art Online could be possible. The head gear would have to read the signals the brain transmits. I have seen something from Japan that can read the signal which is just cat ears you put on your head and when you think of them moving they move. The head gear would also have to induce a type of paralysis similar to that which the brain induces when you sleep so that you don’t move like you do in your dreams. It would also have to send signals to your brain in order for your brain to think it is seeing, feeling, tasting, etc. everything that is happening in the game. This is a downside though because it could be very dangerous if someone found a way to use this to send what they wanted into people’s brains. The security would have to be very high in order to prevent this.
