최근 많은 이용자들이 음성채팅을 이용하여 게임을 즐긴다. 하지만 많은 사람들이 게임 내에서 지원하는 음성 채팅을 사용하지 않고 별도의 음성 프로그램을 사용하고 있다. 현재 게임 내 음성채팅과 외부 음성채팅 모두 편의 기능이 많이 부족하며, 가장 큰 문제점으로는 사용자 본인이 직접 음성 채팅에 참여하는 유저를 구해야 한다는 것이다. 본 논문에서는 이러한 불편한 상황을 없애기 위하여 자동으로 음성 채팅이 가능한 사람을 모집하여 좀 더 편안한 게임 환경을 제공할 수 있는 음성 채팅 웹 서비스를 개발 하였다. 웹 크롤링 기술을 이용하여 외부 커뮤니티등의 구인 글을 크롤링 하여 설정한 조건과 구인 조건이 일치하면 사이트 사용자 뿐 만 아니라 미사용자 간의 매칭도 빠르게 지원 하도록 개발하였다.

ICT 기술발전으로 웨어러블 디바이스(wearable device)와 증강현실(augmented reality: AR) 및 가상현실(virtual reality: VR)등은 차세대 게임 산업에 새로운 재미와 가치를 부여할 기술로 주목받고 있다. 특히 가상현실 기술은 컴퓨터 시뮬레이션으로 창출된 3차원 가상공간으로 사용자가 현실 세계에서는 직접 경험하지 못하는 상황을 간접 체험할 수 있어 실재감과 몰입감을 경험하게 한다. 게임에서의 몰입과 실재감은 게임이용과 만족도에 큰 영향을 미치는 것으로 연구되고 있다. 따라서 본 논문에서는 가상현실을 이용하여 유저와 상호작용하고, 사용자에게 현실과 유사한 긴장감을 줄 수 있는 극한 도망 게임을 개발하였다.

While a game market has been growing consistently world widely, a market of arcade or video game has been detained. In this stagnation, the latest one in 2015, "Super Mario Maker" of Mario series that's been running in good for 30 years, the notable sale and growth of which are extraordinary. As for a study in customizing, a literature of game customizing and studies that are foregone were mostly handling contents about a game character. In the survey that's done in this thesis about knowledge and needs in customizinge game users have, it was shown they want to customize sides of a rule and a character. I analyzed what the main factors are in this game which uses a main concept of customizing and the reason for high profits and popularity. As a result of the analysis, four features, possibility to customize a game rule, share data among users, collaboration in marketing with NFC figure characters, offering updates with sustained and new customizing features were found out. I am certain a game customizing will be helping to meet users and be used for various industries without limit of existing character.

The most important service of the online game is the stability. However, in online games, the increase in the number of users burdens the server as thousands of users connect to the server at the same time. While various techniques to reduce the load on the server are studied, the study is limited only to the server part like an improvement of server algorithms. In this paper, a program to handle the largest load of the server, the message synchronization of both the server and client, is designed and implemented.

Online game has been made of total products which user was given the experimental properties of a variety such as fun and the total of hardware and software products. Through this processes, The company earned a profitable benefits, in addition to the user was given satisfactory service. In this sense the parts of the game production process, the service earlier in the game testing a variety of ways needs to the user through the game as a condition for providing the content can be. Contact a professional game testing job is done systematically through the game's completion of a game developed by companies to see that service to complement previous significant. In this study, search for independent testing cases and the systematical cases as experts needs a range of the testing services.

A game engine should have the architecture that can manage various interactions between entities in a game for offering users various game experience. For this purpose, the game engine architecture based on message system is used. But only by this message based system, it is difficult to change game world continuously according to some storylines. The reason of this is event-driven system like message based system is appropriate for processing individual message but is not appropriate for processing more bigger logical work unit. For this purpose this paper proposes the storyline entity. The storyline entity has logical flows for a storyline and is called by engine continuously. By this proposed game engine architecture he or she can maintain free game experience by message based system and can add some progressing of storylines.

Cheating detection models in the online games can be divided into two parts. The one is on client based model, which is designed to detect malicious programs not to be run while playing the games. The other one is server based model, which distinguishes the difference between benign users and cheaters by the server log analysis. The client based model provides various features to prevent games from cheating, For instance, Anti-reversing, memory manipulation and so on. However, being deployed and operated on the client side is a huge weak point as cheaters can analyze and bypass the detection features. That Is why the server based model is an emerging way to detect cheating users in online games. But the simple log data such as FPS's one can be hard to find validate difference between two of them. In this paper, In order to compensate for the disadvantages of the two detection model above, We use the existing game security solution log as well as the server one to bring high performance as well as detection ratio compared to the existing detection models in the market.

Because development of high speed network, spread of internet, and high quality of computer performance, request and internet about massive multiplayer playing the game, is increasing. In order to experience realistic game play which is one of the most importance factor in massive multiplayer on-line, synchronization is importance matter. We propose synchronized and optimized scheme that combined FSM (Finite State Machine) and event holding method for efficient state synchronization for massive multiplayer on-line, and we show the effectiveness and reliability of our proposed scheme through the implementing and testing of the game server applying on our proposed scheme.

In this paper, we consider a beamforming game between the transmitters in a two-user multiple-input single-output interference channel using limited feedback and investigate how each transmitter is able to find a modified strategy from the quantized channel state information (CSI). In the beamforming game, each of the transmitters (i.e., a player) tries to maximize the achievable rate (i.e., a payoff function) via a proper beamforming strategy. In our case, each transmitter's beamforming strategy is represented by a linear combining factor between the maximum ratio transmission (MRT) and the zero forcing (ZF) beamforming vectors, which is the Pareto optimal achieving strategy. With the quantized CSI, the transmitters' strategies may not be valid because of the quantization errors. We propose a modified solution, which takes into account the effects of the quantization errors.

MMORPG Quest plays a strong role of motivation through compensation related with Avatar such as items and experience points rather than a role of story transfer. This situation finally made MMORPG become a difficult game that players should study the compensation of Quest for growth of a character, so it causes fixation of the user class. As a solving method of the fixation of the users, the possibility of Quest capable of strengthening play motive of various users through clarification of motivation structure of the Quest play and pluralistic understanding about players was investigated. This is a direct response to the user within the game system or how to use the player log information. The pluralistic understanding method of players will have values as a tool that can guarantee the objectivity and actual production of the data collected utilizing.
