@Geoffrey, stereo vision has nowhere near the accuracy they mention, and requires a lot of computational power. You need a state of the art graphics card GPU, just to get decent results in real-time from 30fps HD videos. And the solution will easily break apart if the conditions aren't ideal.

@John- Good point. Though with some on chip focal plane processing, smart allocation of cpu cycles, and a few application specific assumptions I can see a stereo implementation in a package that size (thought not that price point).

Saw a posting somewhere suggesting the device is actually two cameras, an IR filter, and an IR source, probably projecting a structured random dot pattern like the Kinect. Implementable in a package that size, with the right techniques, but I think in this case the work is being done on the host computer.

it's been stated here that it's not a TOF camera.

Leap Motion’s Eliotte weighs in on the tech “the camera is not a time-of-flight camera. The device is actually using camera sensors that are basic off-the-shelf hardware found in smartphones and webcams today. The 3D magic comes in the software –the mathematical analysis of the light bouncing off images.”

It doesn't work with women or anyone over 25.
