Hi @annamarymondol
We've been working on this in our project recently - and are trying to develop a layered system so our gesture can be used for multiple purposes. This is under active development, but there are a few examples of defined gestures. (Rereading this I want to make clear that we are a lab developing a project that uses leapmotion but we are not leap motion)
