>What's inside out tracking?

Because the Quest is a completely standalone device, the headset itself tracks your controllers rather than external sensors mounted in your room. There's no camera on the back of your head so there's a blind spot behind you - See pic related right hand side. It also means you can't play in the dark, because the headset needs to be able to see the walls floor etc of your room.

Oculus' inside out tracking is the best in the industry so unless you're a poopsocker trying to get world records in Beat Saber I wouldn't worry about it.
