Gesture recognition (basic swipe detection) for desktop application

Hi
I want to use Openframeworks for gesture detection using video feed from a simple webcam. Primarilly interested in basic swipe detection. There are so many options when it comes to OpenCV, and since I am a C++ novice, want to make things ‘plug and play’ as much as possible. My plan is to feed the data out via OSC to a Unity 3d front end.

Can any OFX-OpenCV experts chime in with their recommendations? I cam across this project which may be overkill for my needs
