First experiments with Leap Motion and Cinder

After months of everyone sharing the Leap Motion demo video, the first Developer Kits are making their way into the hands of those that signed up early. Dofl Yun was one of the few to receive it last week, Leap Motion Dev Board (v.04) and with some help from Robert Hodgin and Andrew Bell with the setup, he has shared the early progress.

For those that do not know, Leap Motion is a 3d depth camera much like Microsoft Kinect except provides much better precession. It aims to represent an entirely new way of interacting with your computers. It’s more accurate than a mouse, as reliable as a keyboard and more sensitive than a touchscreen. For the first time, you can control a computer in three dimensions with your natural hand and finger movements.

Experiment I: Spaceship Racer Prototype
This prototype shows that controlling position of camera in 3d space by tracking two hands.

Experiment II: Mesh Builder
This prototype shows that how to add points by tracking fingertips and generate triangle meshes in 3d space by connecting points.

The company is estimating that the leap will ship in early 2013. Below experiments were built with C++ and Cinder.

    i thought it detects gestures by infrared optics and cameras instead of depth o.O
