One of the most unique experiences I had was focused all around not only a virtual reality headset, but a ring that fit on my finger. This ring was not only very stylish, but was a controller with all the functions of a handheld gaming console control. 
The ring fits over your index finger and you tap on it to fire and your thumb is used to move backwards or forwards and with a quick wrist flick the left or right you can cycle your weapons. The way you go depends solely on which way you’re looking. If you want to go left look left and press the ring, want to back up use your thumb to press button at the top to back up. Everything is there for you to use and only takes a 3 fingers. The level that was being demo’d reminded me of the movie Akira, because a lot of stuffed animals were coming to life and instead of psychic powers you shot them down with a number of guns. I cycled through the handgun, the machine gun and I ended up sticking to the minigun, because it was so satisfying mowing down enemies. If the ring is comfortable to you, then they also have the new backspin available
The new backspin control offers a more familiar feel to the controllers out now, but while still keeping with their unique design.
