Hand gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Also, gesture is good interaction way when using computer for kids or disabled. Especially, gesture is good educational way for kids. We can see many kinds of serious game using gesture. In this paper, we developed serious game for kids using 'Leap Motion' based on honey bee dance. There are many gesture recognition ways as Kinect 1 , Leap Motion 2 or Wii Remote 3 . These devices are easy interaction device also game controller. Our research is focused on hand gesture, so we used Leap Motion. Development of Leap Motion is affordable and convenient structure. After investigation of honey bee dance, we applied it into serious game. The dances are performed by worker bees that have returned to the honeycomb. It essentially is a language that tells the other workers where the food is. In our developed game, kids can learn these honey bee dance using their hands via Leap Motion. Leap Motion is a computer hardware sensor device that supports hand and finger motions as input, analogous to a mouse, but requiring no hand contact or touching. The movement of the hand is good for kid's brain development. It has already been proven through many materials. Kids can learn the language of bees through developed game and it is a natural form of play. Our system can propose the new development direction of serious game, also potential of Leap Motion as serious game device.
