The Nimble Sense camera is a skeletal-tracking camera/laser combination based on PMD Technologies' chip -- it picks up and tracks human skeletal movement, as well as creating a point cloud of the world around you. It's not quite pass through vision (seeing "through" the VR headset into reality), but it enables a blurry version of your own body and the world around you. Enough so that you could, say, drink from a cup.
The device attaches directly to the top of the latest Oculus Rift dev kit (DK2) via a 3D-printed mount. It points down at an angle, intentionally aimed at your hands while you look straight ahead.
If you think this sounds like Leap Motion, that's because it's very similar to Leap Motion. Nimble actually created a video explicitly showing the difference....
Nimble VR's Sense camera is still a prototype, and the only way to reserve one is chipping in $99 on Kickstarter. The group's already surpassed their goal ... June 2015 promised delivery date.
