“First, YouTube now supports VR video—a brand new kind of video that makes you feel like you’re actually there. Using the same tricks that we humans use to see the world, VR video gives you a sense of depth as you look around in every direction. Near things look near, far things look far. So if you were excited about 360° videos, this is pretty freakin’ cool.
To give it a try just find a VR video on YouTube—like the Hunger Games Experience or TOMS Shoes Giving Trip—tap the new Cardboard icon, drop your phone into your Cardboard viewer, and you’re off! If you’re a creator, you can also check out technologies like Jump to capture and share your own VR videos.”
“And that’s the fact that you can now watch any video using Google Cardboard, and experience a kind of virtual movie theater. Just select the new “Cardboard” option from the watch page menu, drop your phone into your viewer, and you’re done. You’ll now have the largest VR content library right at your fingertips.”
