Mobile game is a killer content among the various mobile contents provided by Telecommunication companies. Recently, Location Based Service (LBS) market is growing rapidly and LBS will be a killer content in the near future. As a consequence, mobile game combined with LBS will be a dominant trend of mobile content. However, there exist some limitations on the revitalization of the mobile service market. In this paper, analysis of the restrictions on the mobile service market is performed and then methods for the revitalization of the mobile service market are proposed various billing system is required to reduce network fee for users, a new policy to protect privacy has to be offered, and the infrastructure for high network performance should be developed. The result of this research will provide key role to find a new and more innovative approach to enhance the interaction design of the future Location Based Mobile Games.

An on-line game is growing of very fast through characters of the interactive Computing and internet environment. In addition, an edu-game combing the advantages of the game and the education increase gradually. The paper proposes an edu-game system for providing knowledge through the hierarchical structure. The system differs from existing ones that combine a game and an on-line education. There are three different goals as follows. First, the paper proposes three-level of knowledge hierarchies. The method enables users to understand more easy and systematic and interesting education. Second, the graphic interface of a puzzle type is able to contact more conveniently and it provides beauties and functionalities. Third, Among them, specifically the knowledge hierarchy is not forced to users and the method also can study in detail and users can enjoy systematically e-education by using the general type of a puzzle game.

The need of high quality VR contents has been steadily raised in recent years. Therefore, this study investigated the user's interest factors of VR game which is receiving the most attention among VR contents. We used STEAM review data and applied Text mining and Network analysis to perform this research. As a result, it was possible to confirm 4 word clusters related VR game users. Each cluster is named by 'presence', 'first person view game', 'auditory factor' and 'interaction'. This study has its meaning. First, user related research would be very helpful to develop high quality VR game. Second, it confirms that review data of VR game users can be structured, analyzed and used.

최근 온라인 게임은 많은 호황을 누리고 있다. 현재는 PC 기반의 온라인 게임이 주류를 이루고 있지만 무선 단말기를 통하여 온라인 게임을 즐기는 사람들이 급증하는 추세이다. 기존의 온라인 게임서버의 구조를 살펴보면 각각의 게임의 환경에 맞게 서버를 설계하여 많은 시간과 자원의 낭비를 초래하게 된다. 유사한 Network Game을 지원하기 위해 헤더 영역과 Data영역을 분리 시켜 보다 유사한 게임들은 동일한 게임서버를 통하여 지원을 가능하게 하여 효율적인 게임서버를 운영할 수 있을 것 이다. 따라서 본 논문에서는 유선과 무선상에서의 Network delay를 고려한 유뮤선 네트워크를 동시에 지원하는 Game Server및 미들웨어를 구현하고 구현된 Game Server의 성능분석을 통해 본 논문에서 제안한 게임서버의 분산처리 성능을 평가하였다.

오늘날 국내외에 인터넷 보급의 대중화가 점차 확대되고 네트워크을 이용하는 게임의 증가에 따라 게임에 관련된 웹 문서에 대한 사용자의 요구가 증가되고 있다. 기존의 수작업에 의한 색인 방식은 많은 전문인력, 시간, 경비등을 필요로 하기 때문에, 기하급수적으로 증가하는 웹 상의 정보를 처리하기에는 이미 그 한계에 이른 실정이다. 이러한 문제점의 해결을 위해 컴퓨터를 이용한 자동색인 시스템의 개발은 매우 중요하고 시급하다. 더구나 게임 분야에서 있어 신조어는 너무나 급속히 생성되고 있다. 따라서 이러한 신조어 처리는 효과적인 자동색인을 위한 중요한 요소이다. 이 논문에서는 사용자들에게 보다 적합하고 안정적인 게임 정보를 제공하기 위해 게임 용어 사전을 이용한 자동색인과 신조어 처리 시스템을 설계, 구현한다. 자동색인 및 신조어 처리를 위해 게임용어사전, TF-IDF, n-gram 추출법을 이용한다.

본 논문에서는 서로 다른 곳에 구축되어 있는 이기종 가상환경을 네트워크로 연동하고 이러한 환경에서 3D 게임을 지원하기 위한 시스템 설계 및 구현 결과를 제시한다. 각각의 가상환경은 수평-수직-정방형 디스플레이 장비 및 마그네틱-하이브리드 방식의 트랙킹 장비를 이용하여 구축되었다. 제안 시스템에서는 서로 다른 형태의 디스플레이, 트래킹 및 인터랙션 도구로 이루어진 개별 가상환경을 연동함으로써 발생하는 데이터 간의 이질성을 해결하기 위한 뷰 동기화, 인터랙션 동기화 기법 및 사용자 인식 모듈을 제공한다. 또한 별도의 컨트롤 서버를 구축하여 개별 노드간의 동기화를 제공하고 공유 데이터를 효과적으로 관리할 수 있도록 하였다. 개발된 환경 및 시스템에서 "Alice in Virtual World" 라는 1 인칭 슈팅 게임을 수행하여 그 활용 가능성을 입증하였다.

Recently, the social network game (SNG) industry is expanding at a fast pace by the increase in the charged item sales. The objective of the present study is to explore factors influencing user intention to purchase charged items. Based on the literature review, flow has been introduced as an influential factor of the intention to purchase and individual influence, social relationship, and social influence as factors of flow. Enjoyment and self-competence are assumed to be measurement constructs for individual influence, social interaction and self-presentation for social relationship, social norm and perceived critical mass for social influence. Empirical analysis show that enjoyment and self-presentation has significant influence on users' flow while self-competence and social interaction has not. Also social norms and perceived critical mass directly influence intention to purchase items. Theoretical and practical implications are discussed by this results.

Distance learning systems that teacher and learner(s) are located at remote have been in progress in a way that directly transfer the video and audio. To get the interest of learners and effectiveness of education or to overcome the poor network environment, various methods utilizing computer graphics in the distance learning system have been attempted. This paper describes a design and implementation of a distance learning system using 3D animation control technology based on Kinect and network game technology. Distance learning system designed and implemented in this paper is a good example of combining education and game technology. And I expect to be used at various educational contents in the future.

The network performance of MOGs(Multiplayer Online Games) can be measured by the amount of network loads and the response times on user inputs. This paper introduces a frame locking algorithm and a game turn algorithm that have been used for game synchronization in the area of RTS(Real-time Strategy Simulation) Games, a kind of MOG; the results of performance evaluation of these two algorithms are also given. In addition, a server architecture for MOG servers in which replacing synchronization algorithms can be done easily for pursuing efficient performance evaluation, is also introduced.
