Character customization means a series of processes to build a characters. Mobile character customizing system is very scarce than Online RPG system qualitatively or quantitatively. In this paper, I will propose some effective elements about A DIY character system that must be suitable for the mobile environment system. The reasons why Select System is mainly used as the customizing system in RPG are as follows; First, the screen of a mobile device is small; Second, it is due to the space-time characteristics with which mobile games are played. In the middle of playing a game, a customizing system should be adopted in order for players not to feel bored. In addition, avatar's costumes should be continually updated.

In this paper, novel ubiquitous concept of real reality robot game controlled by a mobile server robot is proposed. Real reality robot game means that two real robots controlled by humans/computers through the internet are playing a boxing game. The mobile server robot captures playing images of the boxing game and sends them to GUI on the screen of human operators' PC. The human operator can login to the boxing game from any computer in any place if he/she is permitted. Remote control of a boxing robot by a motion capture system through network is implemented. Successful motion control of a boxing robot remotely controlled by a motion capture system through network can be achieved. In addition, real boxing games between a human and a computer are demonstrated.

In this paper, we developed digital TV interactive game using mobile device. This enables a TV viewer to participate in the game using mobile devices. Recently, advanced interface is adopted in the mobile devices, especially touchpad type interface is favorable. Such type interface has the advantage of more familiar interface for users, and the user can input various type of action. Using a mobile phone enables many users can participate in the TV game, and provides a private screen. In this paper, we describe contributions of the program in detail, and we present the architecture and a demonstration of the proposed program in a similar broadcasting environment.

Recently the unprecedented progress of Android platform and Google Play has brought more opportunities for individual mobile game developers. When playing an Android 3D game, users can accidentally hit HOME Key or BACK Key or receive an incoming message. Subsequently, another screen will appear on top and make the game application lose focus, or the operating system pause that game. These interruption events may also lead to the loss of game information or the game runs out of user control if that game cannot catch interruption events itself and resume at the exact time. As same as other mobile platforms, Android platform also provides Activity Lifecycle methods to help the game application control interruption problems. However, these methods are not adequate to solve all the interruption events. By implementing ANDCube game, we examine most of the possible interruption cases and propose some solutions to help Android game developers avoid some common interruption cases. Concurrently, we show the ways how a game application can catch all unavoidable interruption events and effectively resume from interruption to obtain a high quality game.

Since the advent of digital games, game of the core platform has been changed from the arcade to the mobile device. I consider that I try to seek the direction of the use of game which works for PC and mobile in comparison to analyze the changes in the game graphics. Effects of three types of game platforms on the game graphics, change depends on the game of the genre and game graphics. By reduction of the screen size, a new interface was appeared. However, as directly applying the PC version of the interface, it has brought about a user's inconvenience. I have found that mobile hardware development have not been affecting the game graphics. The common point of PC and mobile, they both have the limit of the platform which they own. There is a need to take into account the differences of graphically elements to use the player language interface.

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.

In this paper, we propose a new framework to control VR(Virtual reality) contents in real time using user's mouth-wind and acceleration sensor of mobile device. In VR, user interaction technology is important, but various user interface methods is still lacking. Most of the interaction technologies are hand touch screen touch or motion recognition. We propose a new interface technology that can interact with VR contents in real time using user's mouth-wind method with acceleration sensor. The direction of the mouth-wind is determined using the angle and position between the user and the mobile device, and the control position is adjusted using the acceleration sensor of the mobile device. Noise included in the size of the mouth wind is refined using a simple average filter. In order to demonstrate the superiority of the proposed technology, we show the result of interacting with contents in game and simulation in real time by applying control position and mouth-wind external force to the game.

A smart phone has an error if we design games on it because smart phone should be able to have input and output simultaneously through the screen. Using the existing layout of the game as a base for research, the layout was divided to four categories that are information area, informational appearance area, operation area and inutility area. Given the research results, we developed an authoring tool to design games for smart phones. Moreover, we applied the authoring tool to develop games and effectively reduce the developing time.

Mobile phone has become one of the most essential thing in modern life. In the past, it was only means of cummunication among people. But now, the function of mobile phone is getting diversified. People listen to music, take pictures and play games with their mobile phone. According to the Research in Jan. 2005, members of Korean 3 mobile cummunication companies were 36 million. And the Research in Jan. 2006 shows that number of 2 million and 16 thousand of members are incresed in a year. (36million to 38million 16 thousands) Mobile game is the most popular fuction among teenagers. People like mobile game becase they can enjoy the mobile game anywhere with easy and simple way. So some companies are even launching dedicated phone for mobile game. And with the unification of platform, people can enjoy various kinds of mobile game now. Most of the mobile character bobies are divided into 2 parts such as 'Head parts' and 'Body parts'. If the body is divided into more than 4 parts, it is difficult to express emotions and actions of the character becase of the small screen of mobile phone. That is why most of the characters have 2 parts - divided body. I stadied how the Design Factor of Mobile Characters such as materials of characters, shape of characters and Frame of accessory's movement are used in the mobile game.

The next generation of 3D mobile games market is becoming increasingly active, more as a result of improvement in the CPU speed of hardware phone, embarkation of 3D engines and high memory capacity, In response to this trend, popular 3D games of PS2 (PlayStation2) and popular online games are being launched as mobile games. However, mobile units have different hardware characteristics compared to those of other platforms such as the PC or the game console. Therefore, mobile game versions of the popular PC games face many limitations in many aspects such as in battery capacity, size of display, capacity of the game, and other user interface issues. Among these many limitations, study for allowing low capacity storage of the game is becoming important. In addition, realistic animation of the 3D character on the small screen of the mobile unit is more important than any other matter. The purpose of this study is to find a solution to providing realistic 3D character animation, and for decreasing the storage capacity of character animation for application in 3D mobile games.
