Starting today, audiences can experience the most immersive “neat marketing thingie” Hollywood has to offer. As a tie-in to Christopher Nolan‘s Interstellar, Paramount and IMAX are shuttling an interactive exhibit to four cities across the country. At whichever population center is closest to you — LA, NYC, Houston or, strangely, Chantilly, Virginia — strap on an Oculus Rift headset and experience some simulated virtual gravity from inside the Endurance, the spaceship from Nolan’s film. An “Oculus Rift,” in case you were looking at those words with the same cocked-head confusion as a dog hearing another dog on TV, is this: virtual reality. Or, at least virtual reality for your face; the Oculus Rift is a boxy, black goggle-like eyepiece that lets you see into a digitally-created world, translating all your head and eye movements so you can look around and see digitally anything you want. Digitally. For the most part, the Oculus is confined to video gaming. Its from-the-neck-up limitations are most easily solved with a mouse and keyboard, although laughably dumb-looking inventions like the virtual reality treadmill and the virtual reality bodysuit pop up every now and then.
