Leap Motion gesture definition and recognition

I need a tool for leap motion that will be abble to learn and recognize gestures taken from sign language. Such gesture can look like [login to view URL] here on videos. I want to abble to train leap motion by making infornt of it gestures (or better way) and put a text when a specific gesture is recognized as output. If there is any solution that you can use it is no problem for me. The solution just must be adapted for training and outputing as easy as possible for non programmer. I found somethink like [login to view URL] but in this solution there are few problems: - finger are dissapearing in many cases - when I put leap motion in front of me or on my chest it is also unable to properly recognize. Probably it must be adjusted. If you can write your own solution for this or use any and adjust it for my needs it is project for you.
