I have seen this a few times now so I know it is not a one off, but it seems that the sleeves of my shirt seem to throw off the Leap Motion sensor and it detects it as another hand - and ends up showing three hands.
I thought it was my watch which might be causing some issue, but that was not it. It goes away when I am wearing a t-shirt, but the tracking is quite off when wearing a full sleeve shirt.
I have been meaning to record a video, but not had a chance to do it yet. I was wondering, has anyone else also seen something similar?
