Zuckerberg showed off a very brief teaser video of the prototype device, but warned that the project was still in it's early stages. Still the headset looks familiar -- aping the comfortable frame of the full Oculus Rift, but lacking its collection of wires. Instead it, it has a (presumably lightweight) computer system mounted into the back of the headset's rigging, and does "inside-out tracking" using cameras to judge the headsets position instead of external sensors. Within seconds, the teaser was over. Oculus doesn't even have a name for the project yet, but it's success could create a new, third category for virtual reality -- a cheap, portable, accessible and high quality experience. Sounds good to us.
