Played around with LeapMotion and this UE4-Plugin one day and I’m sorry but it really sucked. Not even the simplest gestures where detected in a reliable way (about 1 out of 10 hit rate and then quickly fireing dozens of events at one). But that’s not be a problem of the plug-in (which looked well-engineered to me), the sensor just sucks. It’s far to unstable, even under standard office light conditions. I am surprised, that is barely worked in this videos. LeapMotion in it’s current form is basically the Kinect of hand recognition.
