The Leap: Gesture control like Kinect, but cheaper and much higher resolution

Before you read any further, watch the video below. It’s really rather awesome — and apparently the video is footage of a real The Leap unit, rather than a computer rendering (you know a device is serious when the The is part of the product name). You will also notice that it doesn’t only detect hand movements and gestures — you can use objects, such as a pen or chopsticks, or, assuming software support, your favorite pet.
Now, having watched the video, you probably have a few questions. First of all, no, we don’t know what hardware is hidden within the The Leap. Leap Motion (the company behind The Leap) has said absolutely nothing about the tech, other than it’s “unlike anything that currently exists on the market or in academia.” Realistically, the device probably uses some kind of infrared LIDAR (radar, but with light) — or perhaps it’s like a high-definition version of Kinect (which only uses a 640×480 camera, meaning it can’t come close to Leap’s 0.01mm accuracy). On the software side, there’s undoubtedly some magic at work, but again we don’t have any details beyond the fact that it uses “a patented mathematical approach.”
While the video is entirely desktop-oriented, perhaps a more compelling use for Leap could be in the mobile space. With 0.01mm accuracy, it would be easy enough to develop a virtual, gesture-based keyboard. On the other hand, for $70 (cheaper than Kinect!), maybe it’s worth having The Leap on your desk just in case you want to do some lean-back surfing, or other things that don’t require you to be hunched over your mouse and keyboard — or the Leap tech could just be built into the keyboard itself. Anyway, holding your arm out for eight hours might be tiring at first, but it would get easier over time. I can just see it now: The humans of the future will all have massive biceps and pecs.
