Virtual reality pioneer Oculus VR doesn't just want to get its products on your head, it wants them in your hands as well. The headset maker has been quietly preparing motion controllers -- devices that let you drive the action and manipulate objects in games with hand and body movements -- to complement its forthcoming goggles, people familiar with the development process say. The result: a more immersive experience in video games and other simulations. But it's the implications of this technology that may have broader impact in the real world. By marketing its own motion controllers, Oculus may upset developers on its platform. More than a half-dozen companies are developing their own motion control devices to compliment Oculus's headset, called the "Rift."
