Oculus’ new wireless prototype could be VR’s next great leap

“Inside-out tracking” is an almost magical phrase in VR. It refers to virtual reality that doesn’t require external cameras or towers in order to let you move through digital space — which, more than simple processing power or image quality, is the real difference between a mobile headset like the Gear VR and a top-of-the-line Rift or Vive. But that’s what Oculus says it’s cracked with a new prototype, known as Santa Cruz.
