Facebook's Quest uses cameras in the headset to figure out where everything is. It's theoretically cheaper than having external sensors or lighthouses, and it makes the system more portable - you don't have to set up the area where you'll be using it. But it's also much less precise and, as seen here, you can't actually see your legs to track them.

Honestly the coolest innovation so far with VR has been the valve index in how it created semi realistic hand representation and tracking.
