Spawning particles according to hand gestures

Is there a way to spawn particles according to the movement of the hand?
I’m trying to create a system where particles are created in line with the hand movements through leap motion.
So far I’m able to spawn them when the hands are on the sensors, but cannot control the direction.

It would be of big help! thank you!

Particle movement can be impacted by a force SOP - so you can use things like turbulence and the like to create interesting movement. Worth knowing about particles is that their direction is driven by their normal. You should be able to use a feedback and object CHOP to derive a bearing which you could then use for driving the direction of your particles.
