It happens every time I strap on the Oculus Rift. Whether the amazing head-tracking wonder that is the DK2 unit or even the earlier model, I’m completely sucked into a new virtual world. Then I look down and my hands and…nothing.

Creating a game controller for VR is a mystery that Oculus has long been trying to solve.
