Leap Motion is unveiling its Leap 3D motion control system, Technology Review Hello World reports.

Leap Motion appears to outrank Kinect in terms of its capability. The technology, reports CNET, can detect motion with up to a hundredth of a millimeter accuracy; it’s nuanced enough to detect fingers, for instance, enabling the possibility of touch-free pinch-to-zoom.

When the device is available for commercial release, it’s expected to retail for around $70. The device itself is fairly simple — a small USB input device (plus an advanced software platform).

There’s a range of possibilities for the technology: consumers might use it to browse the web; engineers could mold virtual clay; designers could draw precisely in 2-D or 3-D; and new gaming possibilities could evolve.

Leap Motion is looking for a “few hundred” developers to get involved with their tech, and soon intend to send out as many as 20,000 free developer kits when it’s officially released — in 2013, according to reports.
