Kinetic User Interface

[Aceix]

Hello all,
I'm thinking of creating a cool visual gesture app for windows, which will use camera as input device. i need suggestions on how to go about it. A hint on how to start(maybe an already established API) would be cool.

You'll probably want to check out OpenCV. It's the go-to library for computer vision things. It includes code to interface with webcams.
