ZeroTouch: Air Gesture Control

I already did the tutorial but it doesn't track my hand,I'll edit to 5 star after it got fixed. edit:decent update, but There's no improved setting such like u load a image for Cursor (after loading image will Have to drag image first otherwise wrong Point Click like for an example u load a Computer cursor image and then click as a pinch and then It only clicks at the middle of image and u can't edit point click)+where's the swipe or Hold (as a drag) tutorial?
