Oculus is buying a company that brings hands into virtual reality
Right now, the term "virtual reality" still means "headset" for most people. What we should really think when we read "virtual reality" is first-person immersion. The headset -- like Oculus VR's Rift, Sony's Project Morpheus, and Samsung's Gear VR -- is simply the first tool for creating that sense of immersion or "presence." But once you're in a headset, the first things you do are the undoable: reach out with your physical hands into virtual reality. It's not exactly surprising, then, that Oculus VR would acquire Nimble VR -- the company behind Nimble Sense, a camera and software combo that brings the world around you into virtual reality. Think of it likeKinect: cameras that are able to track your skeletal movement and create a point cloud around you, which then translate that data into a virtual representation on-the-fly.
Still confused? We've got a video hands-on of Nimble VR's Sense camera from early November below the break, used in-tandem with Oculus VR's second Rift development kit (pictured above).
