This paper proposes methods that can standardize the different content motions that use Leapmotion in order to define and recognize them. A current Gesture interface is built and used to fit the individual contents. This creates confusion among the users because each applied field uses a different motion. Therefore, we defined the motions that were used in the contents in diverse fields into Motion grammar, proposed a method to recognize the defined language through a Motion Tree, and verified its accuracy through experiments.
