Pac-Man Game using Hand Movement without Keyboard and Mouse

Abstract

The game “Pac-Man” is a widely famous and well-loved game in video arcades all over the world. In this paper, we propose a function to substitute central points of hand coordinates for direction keys of the game. With this function, we can play the game with several simple hand movements and without a keyboard or a mouse. The movements of a monster in the game could be performed by those of a hand since it can get video images in MFC(Microsoft Foundation Class) dial log by extracting pointers of the hand. To extract skin color, a binary RGB (Red, Green, and Blue) is transformed into a binary YCbCr video image without brightness. Several operations of product, hybrid median filtering, and AND are performed, in order to get a better video image quality. The central point of a hand can be found by use of the mean of two central points after the central point of a minimum boundary rectangle and a hand is found.
