Mobile shooting games are a representative example of PC games being transferred as they are. In the most mobile shooting games, joystick-like UI used in PC games have been moved to touch buttons, but the display is small, so the user's fingers cover the game screen, which is inconvenient. In mobile shooting games, in order to overcome the limitations of the small display and increase the immersion of the game, this paper introduces a user interface that integrates character movement and aiming, and intuitive UIs such as display rotation, shaking, and vibration. In addition, by analyzing the match process for each round, the character's insufficient abilities are identified and synergies to supplement the abilities are recommended in order to add fun to the game. This paper proved that the proposed goals are achieved by actually designing and implementing a mobile shooting game with the proposed functions on an Android smartphone.

This paper is to review from a developer's perspective about the relationship between game development and the convergence of several disciplines during the game development. As the popularity of smart phones is accelerating mobile gaming it is becoming an area where various types of games that appeal to all ages of users. In this study, the production of a new genre of mobile games that can be enjoyed by all ages apart an existing generalized game and will be described an experience for them. The games built on the game plan, the planning information through the process of creating the actual game. At the same time, it studies on the relationship between each process by several studies.

Mobile game apps, which are popular in various mobile devices, tend to be power-hungry and rapidly drain the device's battery. Since a long battery lifetime is a key design requirement of mobile devices, reducing the power consumption of mobile game apps has become an important research topic. In this paper, we investigate the power consumption characteristics of popular mobile games with multiple threads, focusing on the inter-thread. From our power measurement study of popular mobile game apps, we observed that some of these apps have abnormally high-load threads that barely affect the user's gaming experience, despite the high energy consumption. In order to reduce the wasted power from these abnormal threads, we propose a novel technique that detects such abnormal threads during run time and reduces their power consumption without degrading user experience. Our experimental results on an Android smartphone show that the proposed technique can reduce the energy consumption of mobile game apps by up to 58% without any negative impact on the user's gaming experience.

The mobile internet has grown ubiquitous across the globe with the widespread use of smart devices. However, the designs of modern mobile operating systems and their applications limit content retrieval with mobile applications. The mobile internet is not as accessible as the traditional web, having more man-made restrictions and lacking a unified approach for crawling and content retrieval. In this study, we propose an automatic and scalable mobile application content crawler, which can recognize the interaction paths of mobile applications, representing them as interaction graphs and automatically collecting content according to the graphs in a parallel manner. The crawler was verified by retrieving content from 50 non-game applications from the Google Play Store using the Android platform. The experiment showed the efficiency and scalability potential of our crawler for large-scale mobile internet content retrieval.

A smartphone is a mobile device that has smiler to the computing power of the PC. People who use smartphone applications are increasing and there are a lot of applications for smartphones. Applications for educational games and hence of Korean traditional culture are still insufficient. To do this, we develop Gonu which is a traditional game.

Hardware technology will be widen the area of involvement. If the smart phone capabilities by the pc, PC-free areas will have much higher utilization of smartphones. even subway or bus. and You also enjoy the game and information that you want to connect to the Internet. Because of the advantages of these smartphones, the world market has become more spread by the phone. In the recently, You need to boot your PC or notebook. In this project, using the GPS feature, and Android hiker safety and convenience applications for the purpose. Consumer-friendly via search for the mobile devices around the mountain and near by mountain. and we may be able to help the trail more easily research and develope that were using.

Many people are now enjoying mobile games using various smartphone platforms. However, we have to develop games separately for each smart device platforms so far. Cocos2d-x, a game development framework is released to solve this problem. As a multiplatform version of the existing Cocos2d, Cocos2d-x can make one source code run on various platforms. It is an open software that is able to be used by everyone, and when using it, mobile games can be developed easily based on C++ and OpenGL. In this paper, we implemented a PC laboratory decorating game application, named ILove501, using Cocos2d-x. The 501 is a room number of our PC lab. ILove501 includes an educational feature of solving quizzes in order to highlight positive effects of game. For implementation of a multiplatform game, ILove501 was developed in Windows and iOS environment at the same time, and we verified the results of the execution by porting on a variety of devices such as Android, iPhone, iPad and Galaxy Tab.

Embedded System includes touch, GPS, motion, and acceleration sensor, and can communicate with neighbor devices using wireless communication. Because Arduino with embedded system provides good environment for development and application, developers, engineers, designers, as well as artists, students have a great interest. They utilize Arduino in the robot, home appliances, fashion, culture and so on. In this paper, we design and implement a game using Arduino with embedded system which recognizes the human movement by moving away from one-dimensional game of the existing touch method. Implemented embedded system game measures gyro-sensor to recognize human movement and detects the attack success of the opponent by using touch sensor. Moreover, health of the game player is updated in the real time through the android phone-based database. In this paper, implemented embedded system-based game provides GUI screen of android phone. It is possible to select watching mode and competition mode. Also, it has low energy consumption and easy to expand because it send and receive data packet through recent Bluetooth communication.

In the mobile gaming market, it is desirable for a specific content to be served on various platforms. Recently, it is a very important issue in the market for mobile games. This problem incurs extra cost, because we need to redevelop existing contents to be executed on another platforms. Moreover, the release of a new platform has spent much more effort and cost developing many contents in short period of time. Therefore, we need to research about translation techniques that enable the existing contents to run on a different platform. In this paper, we propose translation techniques for mobile games. The techniques can be applied on converting mobile contents to runnable contents on a new platform. To realize it, we design and implement a source-level contents translator which is targeting Android platform using the suggested techniques. Our source-level contents translator is implemented systematically by applying compiler theory. Also, we solve partially translation problems between different programming languages. The translator has been implemented separately divided into three tasks such as kernel porting, library mapping as well as language translation. We expect these techniques to increase utilization of existing mobile games and contribute to vitalizations of mobile contents industry.
