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.

본 논문에서는 결정트리 학습 알고리즘을 활용한 축구 게임 수비 NPC 제어 방법을 제안한다. 제안하는 방법은 실제 게임 사용자들의 이동 방향 패턴과 행동 패턴을 추출하여 결정트리학습 알고리즘에 적용한다. 그리고 학습된 결정트리를 바탕으로 NPC의 이동방향과 행동을 결정한다. 실험결과 제안하는 방법은 결정트리 학습에 시간이 다소 걸리지만, 학습된 결정트리를 바탕으로 이동방향이나 행동을 결정하는 시간은 약 0.001-0.003 ms(밀리초)가 소요되어 실시간으로 NPC를 제어할 수 있었다. 또한, 제안하는 방법은 현재 상태 정보 뿐만 아니라 이를 분석한 관계정보, 이전 상태 정보도 함께 활용하므로, 기존방법인 (Letia98)에 비해 이동방향 결정시 높은 정확도를 나타냈다.

In this paper we propose the methodology for 3D background image construction in computer games. This methodology was developed based on TIP (Tour Into the Picture) using a vanishing line Proposed by Kang et at. The methodology Proposed in this study can simply implement a 3D background for a computer game with a background model which is very complex or based on a real picture. Compared to the graphics technologies generally used, the proposed methodology does not need the process of modeling elaborate 3D information of a background, and hence can display the background even on a low grade personal computer using a small reference image. TIP technology was successfully applied to the implementation of a background model for a computer game and was found to be appropriate especially for real time games.

The social interest for collaborative teaming and educational game has been increased. In this paper, we investigated the educational value of collaborative teaming and game. Based on this investigation, we propose an educational on-line game model for collaborative teaming. Although the proposed model is still conceptual design, it sufficiently shows that on-line RPG game can be a good collaborative teaming method for young children. We will perform a comparison study on the teaming achievement between the two methods: 1) the on-line game proposed in this paper, 2) the conventional educational method performed in normal school.

e-러닝 콘텐츠 및 시스템을 효과적으로 개발할 수 있게 하기 위한 기술 표준안으로서 개발 중인 SCORM은 전세계적으로 가장 많은 e-러닝 관련 업체에서 폭 넓게 수용하고 있는 구현 참조 모델이다. 최근들어 게임을 학습에 활용하고자 하는 노력에 대한 관심이 고조되고 있는 상황에서 SCORM을 개발한 ADL에서는 게임 기반 학습에 대한 기초 연구를 수행하고 있는 실정이다. 그러나 ADL은 SCORM 명세에 대한 연구와 게임 기반 학습에 대한 연구를 분리하여 따로 진행하고 있고 대부분의 SCORM 콘텐츠에 대한 연구는 고전적 훈련 및 교육 방법에 대한 웹 기반 온라인화에 초점을 두고 있으므로, 게임 데이터 요소를 적용한 SCORM 콘텐츠를 개발하기 위하여 SCORM 명세의 구체적인 어떠한 부분을 어떻게 활용할 것인가에 대한 연구는 매우 미흡한 실정이다. 본 연구에서는 게임 데이터 요소를 SCORM 데이터 모델에 적용하는 구체적 방안에 대한 연구를 수행하고 이를 바탕으로 SCORM을 게임 기반 학습 콘텐츠 개발에 적용하는 실제 사례를 제시한다.

구조주의적 스토리텔링 모델인 영웅스토리텔링 모델을 통하여 컴퓨터게임의 스토리를 분석해 보고자 하였다. 주로 전통적 매체를 대상으로 적용되었던 스토리텔링 모델을 게임에 적용하려한 것은, 그 모델이 단순히 이야기의 캐릭터와 사건을 정리한 수준의 것이 아니라 인간의 심리적 본성을 추구하여 만들어진 것이기에 가능하다고 생각하였다. 영웅스토리텔링 모델을 이용하여 고전적 게임인 테트리스를 분석하였는데 7원형과 12여정이 테트리스에서도 유효하게 나타남을 알 수 있었다. 다만, 게임이용자가 직접 주인공이 되는 게임스토리의 특성을 배려할 필요가 있었다.

The payoff game between task publishers and users in the mobile crowdsensing environment is a hot topic of research. A optimal payoff selection model based on stochastic evolutionary game is proposed. Firstly, the process of payoff optimization selection is modeled as a task publisher-user stochastic evolutionary game model. Secondly, the low-quality data is identified by the data quality evaluation algorithm, which improves the fitness of perceptual task matching target users, so that task publishers and users can obtain the optimal payoff at the current moment. Finally, by solving the stability strategy and analyzing the stability of the model, the optimal payoff strategy is obtained under different intensity of random interference and different initial state. The simulation results show that, in the aspect of data quality evaluation, compared with BP detection method and SVM detection method, the accuracy of anomaly data detection of the proposed model is improved by 8.1% and 0.5% respectively, and the accuracy of data classification is improved by 59.2% and 32.2% respectively. In the aspect of the optimal payoff strategy selection, it is verified that the proposed model can reasonably select the payoff strategy.

The purpose of the present study was to scrutinize computer games that can motivate elementary school students through their interactive "edutainment" effects. The types of elements in computer games that students find interesting as learning media and their impact were studied. The current status of Korean computer games, issues related to learning English, and methods to stimulate the motivation and interest in learning by elementary school students were explored. A computer game model for efficiently teaching English to elementary school students through a connection between computer games and education was suggested. In this model, overall games were designed with the focus on the integration of curriculum and content subjects related to learning activities. For games not to be biased toward entertainment and to have systemized learning steps, the games are composed of an introduction, presentation, practice, production and evaluation, in that order. The model suggested by this plan and composition make it possible to approach learning efficiently with entertaining games based on a systematic learning curriculum. As shown above, developing the model of educational computer games can be seen as an opportunity, which can provide amusement and interests and a broad learning experience as an additional learning method.

Smart grid (SG) technology is now elevating the conventional power grid system to one that functions more cooperatively, responsively, and economically. When applied in an SG the demand side management (DSM) technique can improve its reliability by dynamically changing electricity consumption or rescheduling it. In this paper, we propose a new SG scheduling scheme that uses the DSM technique. To achieve effective SG management, we adopt a mixed pricing strategy based on the Rubinstein-Stahl bargaining game and a repeated game model. The proposed game-based pricing strategy provides energy routing for effective energy sharing and allows consumers to make informed decisions regarding their power consumption. Our approach can encourage consumers to schedule their power consumption profiles independently while minimizing their payment and the peak-to-average ratio (PAR). Through a simulation study, it is demonstrated that the proposed scheme can obtain a better performance than other existing schemes in terms of power consumption, price, average payment, etc.

본 연구에서는 인터넷 게임을 통한 학습의 이론적 면모를 살펴보고 인터넷 게임과 관련하여 여러 장르(어드벤처 게임, 시뮬레이션 게임을 중심으로)의 게임의 교육적 특성과 네트워크 요소에 기인한 상호 작용적 특성을 협동학습을 중심으로 살펴보았다. 또한 각종 인터넷 게임을 통한 교육모델을 제시해 보았는데, 이는 게임의 교육적 특징별로 각각의 단계에 맞춰 네트워크 게임을 통한 학습을 실현 할 수 있는 구체적 모델이라 할 수 있다.
