Pacman is known as the terminator of the loved classic game in the world. In this paper, classic pacman game without using a keyboard or a mouse we should be able to play the game with simple hand gestures. In other words, It use motion game to be a substitute for the hand direction key using the center coordinates. Also, movements of the monster is to be replaced depending on your hand movements by extracting a pointer of hand taking pictures in the MFC dialog using Cam. In this paper, YCbCbr image is convert to RGB images to extract skin color, and multiplication operations and hybrid median filtering was used in order to obtain better images. And it is used to obtain movement of the hand area based on obtain the center of gravity of the hand region.

Classic game Pac-Man (Pacman) is playing a game using a somple hand gasture without using a keyboard or a mouse. In other words, it is a joystick game by motion to replace the arrow keys using the center coordinates of the hand. In addition, the pointer of hand is extracted by accepting images to MFC dialog using cam. Thus, movements of the monsters is to be replaced by hand movements. In this paper, smoothing, expansion, and erosion operation for the skin color extraction, and RGB images are converted to YCbCbr images.

Pacman is one of the world-famous and have been chosen game in the game room at the arcade. In this paper, pacman game gives you the ability to perform by simple hand movement alone. First, we obtain binary RGB image to extract skin color, and convert into binary image YCbCr by minus the luminance in this image. Next, we extract the hand region by the product of an binary RGB image and binary YCbCr image. Finally, the hand region, we obtain the center of gravity by the minimum bounding rectangle and the center of the hand pixel area, and we used to obtain the center of the hand area with an average of two center of gravity. In other words, we presented the game of motion that can take the place of arrow key by using the center coordinates of hand. In addition, these experiments showed the average movement and error rate, and cause of the error type was also investigated.

Genetic algorithms find the optimal solution by mimicking the evolution of natural organisms. In this study, the genetic algorithm was used to enable Pac-Man's reinforcement learning, and a simulator to observe the evolutionary process was implemented. The purpose of this paper is to reinforce the learning of the Pacman AI of the simulator, and utilize genetic algorithm and artificial neural network as the method. In particular, by building a low-power artificial neural network and applying it to a genetic algorithm, it was intended to increase the possibility of implementation in a low-power embedded system.

As the popularity of casual games, they are increasing the needs to satisfy personal dispositions and the gameplay requirements of the various users in the game development process. These require analysis of action patterns of gameplay of various users in the testing phase of the game development. In this paper, we propose a method to analyze action patterns of gameplay through Petri net model simulation with gameplay metrics data. The proposed method has practical simulation environments because of using gameplay metrics data, and it can analyze diversely like reachability, coverbility, and liveness given by Petri net model analysis. An application example of the proposed method using a Petri net modeling tool GPenSIM v4.0 is given to analyze the patterns of gameplay in game Pacman. The results of simulations is presented. The presented results show that the proposed method can analysis patterns of gameplay diversely.

전자 오락실에서 고전 게임 팩맨을 접하지 않은 사람이 없을 정도이다. 본 논문에서는 키보드나 마우스를 이용하여 게임을 수행하지 않고 간단한 손동작만으로 게임을 진행 할 수 있도록 한다. 손 좌표의 중심점을 활용하여 상하좌우 방향키를 대신할 수 있도록 한 모션을 이용한 조이스틱 게임인 것이다. 그리고 웹 카메라를 이용하여 MFC 다이얼로그에 영상을 받아 손에 대한 포인터를 추출하여 손의 움직임에 따라 몬스터의 움직임도 바뀌도록 한다. 손의 피부색상을 추출하기 위해 스무딩, 팽창, 그리고 침식 연산을 수행하도록 하며 손의 RGB 영상을 YCbCbr영상으로 변환하여 전체 게임을 진행한다.

Mucolipidoses II and III alpha/beta (ML II and ML III) are lysosomal disorders in which the essential mannose-6-phosphate recognition marker is not synthesized onto lysosomal hydrolases and other glycoproteins. The disorders are caused by mutations in GNPTAB, which encodes two of three subunits of the heterohexameric enzyme, N-acetylglucosamine-1-phosphotransferase ML II, recognizable at birth, often causes intrauterine growth impairment and sometimes the prenatal "Pacman" dysplasia. The main postnatal manifestations of ML II include gradual coarsening of neonatally evident craniofacial features, early cessation of statural growth and neuromotor development, dysostosis multiplex and major morbidity by hardening of soft connective tissue about the joints and in the cardiac valves. Fatal outcome occurs often before or in early childhood. ML III with clinical onset rarely detectable before three years of age, progresses slowly with gradual coarsening of the facial features, growth deficiency, dysostosis multiplex, restriction of movement in all joints before or from adolescence, painful gait impairment by prominent hip disease. Cognitive handicap remains minor or absent even in the adult, often wheelchair-bound patient with variable though significantly reduced life expectancy. As yet, there is no cure for individuals affected by these diseases. So, clinical manifestations and conservative treatment is important. This review aimed to highlight the extra-skeletal clinical problems in ML II and III.
