We managed to get our hands on a Leap Motion Developer Kit. If you have never heard about Leap Motion then I recommend you watch the video on their homepage.
This is how they describe it themselves:
The Leap is a small iPod sized USB peripheral that creates a 3D interaction space of 8 cubic feet to precisely interact with and control software on your laptop or desktop computer. It’s like being able to reach into the computer and pull out information as easily as reaching into a cookie jar.
The Leap senses your individual hand and finger movements independently, as well as items like a pen. In fact, it’s 200x more sensitive than existing touch-free products and technologies. It’s the difference between sensing an arm swiping through the air and being able to create a precise digital signature with a fingertip or pen.
These are some big promises and I was very happy to experience that they can live up to it. I am amazed by how accurate it is.
To familiarise myself with the Leap Motion and to check out its accuracy I created a demo using Ogre3D, PhysX and the Leap C++ API.
