Gesture-based input for XNA?

Hey folks. I'm working on a project that requires gesture-based input in order to interact with the game. Honestly, I know pretty much nothing about computer vision at the moment, but it's definitely on my to-do list.

One major issue that I keep running back to in my head, though, is how to monitor and receive this input from the already-made game loop in XNA. No matter how much I think of it, I can't seem to come up with even an idea for a solution for this. Perhaps this has to do with my ignorance in computer vision topics and the fact that I'm still pretty much a fledgling developer, but I would greatly appreciate some ideas or to be pointed in the right direction.

The Kinect SDK Beta can be used with C++ or C# on the PC, which means you could use it with XNA. I suspect the SDK for windows wouldn't load on a 360 though. It's probably the cheapest way to get started.

Yeah, I was planning on using the Kinect and learning that the SDK can be used with C# is a load off my mind. Still, though, getting live input in a game loop doesn't seem like a trivial problem. Perhaps I'll need to research with the SDK.

As for what gestures I'm planning on using, imagine something along the line of spell runes/glyphs. Drawing a big M in the air for the camera to see would invoke a fire spell, for example.
