Game level design is one of the important parts in the commercial game development. Because of its complexity in combining game components, game design work could be classified into a non-linear problem. In this paper, we propose a new automated game level design system by using genetic algorithms. With our system, a game designer easily generates an optimized game level by designating the key parameters m the initial stage of game design. Our system can be useful in reducing the trial-errors in the initial game level design process.

Generally, the internet online game systems are divided into two parts, clients and servers. The clients provide a connection with game server to each user and communicate between them. And, the server controls all clients by the game rules fairly and manages database systems to maintain the user information. In this paper, we propose a configuration method for internet online game servers using distributed scheme. To apply this method, we divide game server into three sub-level parts again. First part of game server is login server to establish the connection between communication server and clients. Second part is communication server to connect between clients and main game server during playing the game. And last part is DBMS that performs database independently. Our proposed scheme suggests that the game server operates very stable because of decreasing of processing load by distributed scheme. So, our proposed server configuration applies to similar online game easily.

Breaks in presence (BIP) are those moments during virtual environment (VE) exposure in which participants become aware of their real world setting and their sense of presence in the VE becomes disrupted. In this study, we investigate participants' experience when they encounter technical anomalies during game play. We induced four technical anomalies and compared the BIP responses of a navigation mode game to that of a combat mode game. In our analysis, we applied a linear mixed model (LMM) and compared the results with those of a conventional regression model. Results indicate that participants felt varied levels of impact and recovery when experiencing the various technical anomalies. The impact of BIPs was clearly affected by the game mode, whereas recovery appears to be independent of game mode. The results obtained using the LMM did not differ significantly from those obtained using the general regression model; however, it was shown that treatment effects could be improved by consideration of random effects in the regression model.

Currently the mobile augmented reality does not require supplemental hardware, such as markers like specific images or depth cameras, in order to acquire 3D environment information. This allows for increased accessibility and usability for the general user, and also broadened scope of development. The market research enterprise Counterpoint Research predicted that the growth of the augmented reality market will reach 70 trillion Korean Won by 2021. Application developments are also progressing. Wargaming, the developer of the global game World of Tanks, has launched an application that uses AR core at the GDC 2018. Thus, we must prepare for the impending augmented reality market and acquire top class augmented reality technology using 3D environment. This paper outlines the development of a game using AR CORE SDK to acquire 3D environment and Unity 3D game engine to combine camera images and 3D graphics, which all comes together to construct a natural augmented reality.

In this paper, we propose a game server using public network library ACE, which has been developed in various fields for a long time. ACE network library has been considered not only in the area of high efficient real-time communication library but also in the area of application development, and it provides various facilities. We logically reorganized the part, which is necessary to develop games, among various functions of ACE and optimized it, and developed real battlenet server using verify the reorganized library. As the method of experiment, the battlenet server and test client were set and interface request test and data electrical transmission test were conducted. As the result of the experiment, the conclusion that it is possible to develop games by using ACE, which is verified network library, has been obtained.

One of the most important reasons for using online game is intrinsic motivation which relates the drive to perform a behavior for perceptions of pleasure and satisfaction from the behavior itself. Therefore, most studies for using online game have been based on theories for intrinsic motivation such as flow. However, such theories have some limitations for explaining social aspects of online games such as Massively Multiplayer Online Role Game (MMORPG), which provides a society for game players by using a virtual space for playing games so called 'persistent world'. Adaptive structuration theory (AST) is one of trying to capture the change of using IT due to social interactions between users and system. In order to explain online game players' behavior considering social interaction, we suggest a research model based on AST. Our model aims to investigate the relationship between appropriation which is determined by faithfulness of appropriation (FOA) and consensus on appropriation (COA) and performance which is represented by the relationship among perceived winning, flow, and intention of reuse. An empirical test of our model for 125 MMORPG users which is analyzed by Partial Least Square method shows very satisfactory and interesting results. While hypotheses suggested in our model are supported, the influence of COA on game performance is shown to be stronger than that of FOA.

This research is the qualitative research on signals that mobile game users use to solve asymmetric information of game quality. Based on signal theory, we gathered data using Netnography. The findings are four types of signals for mobile games: platform-based signals with high/low participation rate of consumers, game developing company-based signals with high/low participation rate of consumers. The features that mobile gamers make decisions using signals are the following. First, ranking and the number of download have initial standard. Second, game marketing platform can be one of signals. Finally, the preference of signals is different with the goals and using pattern of games.

With the rise of the game industry, the importance of the game's storytelling is also increasing. Delivering a specific world view of a game has a tremendous effect on the immersion of the game, so the method of delivering a story needs to be studied continuously. In this study, the character was implemented using 3D modelling tool, and the initial story of the game was delivered through a dialogue window using a game engine. Through the research, we were able to establish a workflow for telling stories using a character and understand each process in depth, which we expect to be the basis for more sophisticated game character development and smooth storytelling in the future.

Game Designs & Developers that system designs improve, the product and the change of tasks to all developers are essential in achieving On-Line Game project. Existent Or-line Game project management designs supper the definition and the change of project activities, and configuration management designs support version check, workspace management, build management, etc. In this paper. the proposed Design defines Game component based development process model, and achieves recording of process progression, processing the request of change, reporting the progression of each task, product registering and change, version recording, artifact or form search, etc. using UML. Furthermore, study on the stake holders get the systematic management and standardization by sharing information that are necessary in Game design & development and configuration management in distributed environment using the system integrated management design.

There have been many trials for development of games using augmented reality. This paper presents a 2D puzzle game system using HSV color space to detect hand posture from an input image by smart device's cameras in real time. The developed game in this paper brings smart devices and the computer vision closer. Also this game can be a new interactive technology utilizing both the mobility of smart devices and the tangible interactivity of virtual reality in education and entertainment environments.
