Over the weekend I came across NextMind. It's a new peripheral that takes your brain waves to send commands to things in the world. They are encouraging it to be used for AR/VR/MR.
My only experience with something like this was at the Museum of Science and Industry in Chicago a few years ago. There was an exhibit where they had a band you put on your head to roll a ball. it measured your beta waves and the stronger they were the more the ball moved to your opponent. It really enjoyed it, but it's interesting to see how that technology is applied now in this new peripheral.
I want to know; do you think this will stick around or fade away? How do you see this being applied in the future? How would you apply it to your game?
