How to track hands ?

Hi there,

I’ve looked all over the internet for this, but i wasn’t able to find anything suitable. I want to track hands, and especially the “wave” gesture. Someone is in front of a camera and when (s)he’s waving his hand some feedback must occur. Has anyone some good ideas to track hands? It doesn’t have to be this accurate.

Greetz,
Ruben
