Visual Processing of Rock, Scissors, Paper Game for Human Robot Interaction

There are so many interaction methods between human and robots using visual sensor as camera. In this paper, we try to make rock, scissors, paper game using robot camera. The main problem is occurred by robot height, as more preciously camera height, because hand shapes are dependent on camera angle. If robot's camera height is smaller than human, it is difficult to compare with rock and scissors shape, when human stretch out his hand to the robot camera. To solve this problem, we propose that human stretch out his hand to his shoulder. In this circumstance, we can use skin model to separate human hands using face detector that is base on ada-boosting algorithm including OpenCV library. If we detect a human face, and we made a skin models from detected face region, we can get the robust skin information according to the illumination variance
