Oculus Rift went on sale to the public this week. It's a virtual reality headset that has motion tracking in it along with a camera that can track your body's movements. It also has headphones with very good quality sound. For video, it means that you'll be able to look around and see things all around you. Instead of a camera man or director determining what you'll be seeing, you can look at anything you choose. Gaming is another big use case for these headsets. HTC has made a VR headset called the Vive in conjunction with Steam, a distributor of games for PC.
