As a software component for computer game, the physics engine simulates objects' movement according to the laws of physics. This paper introduces a design and implementation of mobile game on the Android platform, where we used JBox2D physics engine library and Android graphics APIs. We borrowed the key idea of this game from Crayon Physics which is known as a famous PC game. This game starts with no way from user character to destination character. The game user has to make a way to destination character from user character by creating polygon objects between them. The user wins when user character meets destination character. However, the game user has to decide the time to create objects and their shapes well because all objects in this game are governed by the laws of physics. As an important thing of this paper, we introduced into this game new input methods of LCD touch and sensors embedded in mobile devices but not in PCs. Game users can create objects by drawing polygons with LCD touch and move objects or characters according to sensor values from accelerator sensors by tilting the mobile device.

Casual games are easy in terms of control and mode, and thus everyone can enjoy them in their free time. Character games, in particular, feature a variety of cute and attractive characters. Such character games are now available for smartphones, which are used by a large number of users, as well as for PCs. This paper is aimed at demonstrating the design of 2D side-scrolling casual shooting games utilizing Unity 3D Engine, which can be manipulated on smartphones. Unity 3D engine was used because it supports multi-platform with low costs, and it makes it possibile for games to be operated on various platforms using a single program source code. This approach is unique because the design of the games uses cute characters, attractive concepts and easy control, targeting users in their 10s or 20s, unlike existing shooting games that are serious.

In the image processing, foreground image extraction is mainly applied to recognize a moving object or an object. In the game, the objects included in the foreground image can be mainly characters, non player characters, items, and the like. These objects can be the player's primary concern with objects that are the target of players' movement, attack, defense, and collection. In this background, this research is a study to extract players' interest areas. To this end, first, the foreground image is extracted. Second, the extracted foreground image is accumulated for a certain period of time, and the image is displayed as a result image. The accumulated foreground image according to the play time helps to know the location and frequency of screen appearance of game objects. This study can help players design their interest areas and design an efficient UX/UI.

Semiotics studies the structures and systems of all signs related to human life, thus being capable of analyzing games. "Playing games" can be deemed as an act of reading or interpreting games semiotically, which makes game producers "senders," games "texts," gamers "receivers," and gamers playing games "contexts." Since most games are in the multi-variable narrative format, however, it is not a frequent case that gamers interpret games in the ways intended by producers. This study thus set out to analyze and interpret the console game (2001) remembered as the same evaluation by many gamers in the way intended by the producer. For analysis, the study defined its story program by analyzing the plot and sequence. For semantic analysis, the study applied the Actor Model and the Semiotic Square Model to interpret . The process identified such codes as confrontation, assistance, collaboration, and control and confirmed that Ico and Yorda, non-subject characters, were transforming into subject ones. That is, tells a story of the main characters that used to lead a non-subject life earning lives of their own.

When simulating large crowds, it is inevitable that the models and motions of many characters will be cloned. McDonnell et al. analyzed user's perception to find cloned characters. They established that clones of appearance are far easier to detect than motion clones. In this paper, we expand McDonnell's research[1], with the focus on multiple clones and the appearance variety in real-time game environment. Introducing the perceptual organization, we show the appearance variety of crowd clones by using game items and texture modulation. Other factors that influence the ability to detect clones were examined, such as the moving direction and distance between character clones. Our results provide novel insights and useful thresholds that will assist in creating more realistic crowds of game environments.

The objective of this study is to find out how reality game shows, the relatively new television genre, produce a sense of reality and what differences we can find from the reality they produce in compared to that of traditional reality television shows. The researchers anaylized , aired in 2013and 2014 by tvN, with focus on the show's studio setting and characters in the show. During this process, the 'game elements' and 'reality factor' were considered to be the key words. Finally, the reality produces was examined from two aspects: the production and reception. As a result, we found that the reality it produces is more than just a imitation of the real world. It shuttles between the game world and real world, and encourages audiences to recognize the plural realities in our postmodern society. We hope this study stimulates further researches on reality game show genre, which had rarely gained academic attention.

"White Day", a horror adventure game that has gone down in the history of the Korean gaming industry, is not a cruel horror game with hideous monsters and spooky mood, but a Korean-style horror game with auditory effects of ghastly sound. This paper aims at identifying the positive story-telling structure through the components of the game. This study found that the game is based on a well-organized scenario by the background, events and characters. In addition, its design and story-telling structure turned out to reinforce the positive effects of the game, by not imitating the western-style splatter games. As it provides players with playful components that bear mimicry and ilinx to maximize interactive fun, White Day is a prime example of positive games that are strongly needed in this era.

From several commercialized games the technique of changing facial expressions is imported, and a design method of a game character for the player's empathy is expected to be diversified in the future. In this paper, as a design method of a game character for the player's empathy, this makes walking motion for the game character applied with 'human-emotion' factors as statistics variation of a game character in RPG genre. After this paper implements analyzed emotions of human facial expression and walking motions applied with emotion in examples of character animation theory, this paper divides walking motion applied with human-emotion factors into 8 types through relationship to statistics factors in RPG genre. And then these are applied to a knight character, which has the most similarity with human's physical feature of the game characters in RPG genre, and makes walking motion as variable statistics. As a game player controls the game character applied with 'human-emotion' factors, the effect of the player's empathy about the game character becomes higher, and the level of immersion in game play is also expected to increase.

The game market has been converted into PC such as Microsoft X-box, SONY Playstation, and Nintendo, which have been called traditional game consoles. Recently, the mobile game market has been growing as the performance of mobile devices has been reduced. The expansion of the game market is a worldwide trend, and the discovery of game contents are causing many concerns for game companies. Known as the birthplace of animation and games, Japan uses traditional cultural contents to create many characters and game stories. China, which is a latecomer, is also working to find materials for making game contents using Chinese traditional culture. is one of the most successful games in China's online marketplace. The game is designed to allow game users to experience traditional culture by reproducing the images of the time period shown in the wall painting into a virtual space. In this study, I would like to analyze the story of the Buddhist scripture in the mural of Donhwang mural, a Chinese cultural heritage.

Game industry, especially MMORPG (Massively Multiplayer Online Role Playing Game) has rapidly been expanding in these days. In this background, lots of online game security incidents have been increasing and getting more diversity. One of the most critical security incidents is 'Bots', mimics human player's playing behaviors. Bots performs the task without any manual works, it is considered unfair with other players. So most game companies try to block Bots by analyzing the packets between clients and servers. However this method can be easily attacked, because the packets are changeable when it is send to server. In this paper, we propose a Bots detection method by observing the playing patterns of game characters with data on server. In this method, Bots developers cannot handle the data, because it is working on server. Therefore Bots cannot avoid it and we can find Bots users more completely.
