This study analyzes the attitudes of users who use the automatic-play function of mobile-games. It also observes changes in different emotions to enjoyment. For the analysis, the Q methodology appropriate for the subjectivity study was used, and it classified two types of attitudes based on the analysis. After the classification, it defined the characteristic of each type based on Lazzaro's theory on classification of fun. Types with high rate of convenience feature dependency utilize automatic-play feature to play games for collecting and growth, and they prefer managing the game outdoors. Another type enjoyed the experience of problem solving through games. They want the process to be a good skill to possess in game-play. There was also a tendency to perceive oneself as the game's character. Both types were responded positively to using automatic-play to play mobile-games. This is expected to be used as important data for game production, leading to usability evaluation for analyzing the emotional sensitivity of mobile game users.

모델 체킹에서 모델의 크기가 커질수록 검사해야 할 상태 공간이 지수적으로 증가하는 것을 상태폭발문제라고 부르며, 이 문제를 해결하기 위해 추상화 기법이 사용된다. 본 논문에서는 네모라이즈 게임을 대상으로 추상화 기법을 적용하여 게임 모델의 상태 공간을 줄설 기존 방법으로 풀지 못했던 게임을 풀었다. 이 게임은 한붓그리기처럼 출발지부터 이동가능한 모든 지점을 한번만 거쳐, 목적지까지 가는 경로를 찾아내는 도달성 게임이다. 이 게임은 Esterel 언어로 모델링 되었다. Esterel은 동기적 언어로써 게임을 유한상태모델로 모델링하고 관련 모델 체커인 Xeve를 사용하여 모델을 검사한다. Xeve는 모델 체킹 후 특정 출력신호를 방출하기 위한 입력신호들의 시퀀스를 생성해준다. 이 시퀀스가 게임의 해답인 경로가 되는데 Xes라는 시뮬레이터를 통해 실제 정확한 해답인지를 확인한다.

The purpose of this study was to evaluate the usability of a hybrid mobile reading game among 14 parents of children with reading disabilities. The reading game consisted of six steps according to the process of reading (familiarizing with consonants and vowels, acquiring whole words, combining consonants and vowels, reading words, phonological rules, reading fluency). In this study, parents experienced steps one through three of the reading-game app and evaluated the general design features and Universal Design for Learning on a five-point scale. Regarding the general design features, parents rated usability (18 items in total) as high in the following order: interactive design, instructional design, and interface design. Regarding the Universal Design for Learning (9 items in total), parents evaluated usability as high in the following order: providing multiple means of representation, providing multiple means of action and expression, and providing multiple means of engagement. Lastly, suggestions for the improvement of the app, practical implications, and suggestions for future research are discussed.

Digital interactives in museums are expanding and user experience is becoming the focus of exhibition design. The purpose of this study was to suggest guidelines for serious games as a part of museum exhibits. To achieve this, studies on museum education, public space HCI, serious games, and universal design were analyzed by using content analysis methods. Results included 16 quality standards from cognitive, physical, and personal/social models. The findings from this study could benefit the design of future museum gaming interactives.

Recently, mobile games are developed as the various genre and form with the hardware performance improvement and communication network speed increase of the mobile phone. But it shows the limit of the game material to be developed, because the mobile game has to play by using only the keypad handing of the mobile phone. In this research, 'Flip On / Off interface' and 'Microphone interface' were developed in order to utilize the physical device of the mobile phone as the game interface. 'Flip On / Off interface' and 'Microphone interface' have the advantage that there is no need to purchase a device as an additional interface with utilizing the hardware of the mobile phone itself and the progressing of a game is smooth in comparison with the keypad method of the pre-existence mobile game because the interface waiting time for a call response is short. Moreover, by applying to a commercializing game, the developed interface tests, we confirmed an availability at the commercialization inspection standards on mobile phone without the heap memory deficiency phenomenon to be smooth of an operation. Furthermore, in the result of usability evaluation accessability, reliability, and aesthetics were rated as 'high'. The results of this research reveal that the interface environment of the mobile game limited to a keypad will be able to be made with diversification.

As the popularity of casual games, they are increasing the needs to satisfy personal dispositions and the gameplay requirements of the various users in the game development process. These require analysis of action patterns of gameplay of various users in the testing phase of the game development. In this paper, we propose a method to analyze action patterns of gameplay through Petri net model simulation with gameplay metrics data. The proposed method has practical simulation environments because of using gameplay metrics data, and it can analyze diversely like reachability, coverbility, and liveness given by Petri net model analysis. An application example of the proposed method using a Petri net modeling tool GPenSIM v4.0 is given to analyze the patterns of gameplay in game Pacman. The results of simulations is presented. The presented results show that the proposed method can analysis patterns of gameplay diversely.

This research is about development and usability test of 'Paldokangsan4' which is a serious game for the elderly to improve their physical and mental health. This game is the next version of last 'Paldokangsan3' developed in 2013. Its motion capture interface 'Kinect' has been stopped for production that we have to develop the next version with 'Kinect2'. We added a personal ID system to accumulate palyers' game histories, and let the player know the the current score comparing to the personal average score every time. Also we added real mart background to the traditional old market background of the game as well as a tutorial level to learn how to play the game personally. In 2016 Play Expo, we have installed and demonstrated it and gathered opinions of 40 volunteers in questionnaire. The result of their analysis showed that we could find the possibility of beneficial effects for the elderly following the last version.

본 논문은 실버세대의 치매예방을 위한 제스처 인식 기반 3D기능성 게임을 제안한다. 제안된 기능성 게임은 전신 제스처 인식을 이용함으로써 사용자의 두뇌 사용능력과 신체활동성을 증가시켜 치매예방 효과를 향상시킬 수 있도록 구성하였다. 기존에 개발된 제스처 인식 기술에 사용된 카메라들은 인식률과 가동영역이 한계적이다. 보다 안정적인 전신 제스처 인식을 위해 3D depth 카메라로부터 사용자를 인식하고 사용자의 관절 정보를 획득하였으며 관절의 움직임을 분석하여 전신 제스처를 인식하였다. 게임 콘텐츠로는 치매의 대표적인 원인인 뇌세포의 퇴화에 초점을 맞춰 기억력, 논리력, 산술능력, 공간인지능력 등을 훈련할 수 있도록 구성하였다.

클라이언트-서버 구조의 온라인 게임에서 서버의 역할은 매우 중요하다. 그러나 서버에 너무 많은 사용자가 동시에 접속할 경우에는 과도한 부하로 인하여 안정적인 서비스를 제공하지 못하는 경우가 발생할 수 있다. 이러한 문제를 해결하기 위하여 여러 대의 분산 서버를 활용한 방법이 사용되고 있다 분산 서버 구조에서는 부하가 특정 서버로 집중되는 것을 막는 것이 전체 시스템의 성능 향상을 위하여 필요하다. 이를 위하여 부하 평형 기법을 사용하고 있으며 관련 연구도 활발히 진행 중이다. 본 논문에서는 분산 서버를 이용한 온라인 게임 서버의 구조를 설계하고, 대량 사용자의 제약을 극복하기 위한 하나의 방안으로 다중 서버 시스템에서 실행되는 게임 서버 프로세스들에 대한 부하 평형 기법을 제시한다. 제안된 기법에서는 전체 게임을 소규모의 여러 게임 세상(Game World)으로 나누고 서비스가 진행되는 상황에서 게임 세상을 게임 서버들 사이에서 이동시킨다.
