Until recently, virtual reality has been the stuff of science fiction. But last year, Facebook placed a large bet on the future of the medium when it bought Oculus Rift, the leading virtual reality technology company. Oculus VR will start selling its affordable, state-of-the-art setup early next year. Samsung has just released a $99 version of its Gear VR headset. And Google has even made a low-end cardboard device that wraps around your smartphone to turn it into a virtual reality viewer — and, if you subscribe to The New York Times, you recently got one in your Sunday paper. Kurt Andersen visited Stanford University's Virtual Human Interaction Lab, a pioneer in virtual reality research and development, to test drive an experience that’s more realistic than any movie or video game. Now that virtual reality is within months of becoming a consumer product that costs less than a smartphone or video game console, what will that mean for the future of storytelling? Obviously there will be markets for gaming — and pornography — at the start. But, for some directors, the medium has more idealistic applications.
