Todays, with the spread of Mobile devices, game industry has experienced the change of supply chain structure and paradigm. Breaking the traditional supply chain of game industry, mobile games of App. markets provide alternatives or threats against traditional game industry. With the mobility as a strongpoint, mobile games have their own characteristics such as convenience, easy of use and simplicity comparing PC games or other games. In this point, this study is to find success factors of mobiles games through the analysis on the highly ranked favorite games according to the types of mobile games.

This paper proposed a tour game using LBS based on smart phone. This game is based on the historical background of Silla and spatial background of GyoengJu. A Event of tour game uses a smartphone-based LBS. Game events has occurred by comparing pre-measured GPS values and smart phone A-GPS values. This paper has looked at game planning and run screen. In addition, the future direction of the game were discussed.

Virtual Reality (VR) is becoming a new standard in the game industry. PokeMon GO is a representative example of VR technology. The day after the launch of PokeMon Go in the U.S, It has achieved the highest number of iOS App Store downloads. This is an example of the power of VR. VR comprises gyroscopes, acceleration, tactile sensors, and so on. This allow users could be immersed in the game. As new technologies emerge, new and different threats are created. So we need to research the security of VR technology and game system. In this paper, we conduct a threat analysis for information assurance of VR device (Oculus Rift) and game system (Quake). We systematically analyze the threats (STRIDE, attack library, and attack tree). We propose security measures through DREAD. In addition, we use Visual Code Grepper (VCG) tool to find out logic errors and vulnerable functions in source code, and propose a method to solve them.

In many countries, recently computer programming eduction has become mandatory for K-12 students. Generally since programming is difficult for K-12 students to learn, a lot of previous works have been published in which the study motivation and class satisfaction increased when game programming was applied to programming classes. We investigated a research in which we used game programming in the programming classes for middle-school students, and analyzed educational effects. In this paper, we described the specification of the games and our class model that were applied in the research. Also, we analyzed changes made to computation thinking abilities, creative thinking abilities, and perceived support for programming after the programming classes. As a result, it was found that those abilities and the perceived support were increased. Additionally, we applied Havruta learning, a kind of paired learning, in the programming class, and have known that it increased the educational outcome with respect to the traditional method.

Despite the increasing adoption of gamification and its huge potential in tourism, research in gamification is still limited. As preliminary findings show that the effectiveness of gamification depends on the context of its application and the players' use of the gamified app, this paper fills in these gaps: by exploring and analysing the application of gamification in a specific e-commerce tourism context; and assessing the gamification's effectiveness by measuring the players' gamification usage and the latter's behavioural and psychological outcomes. The gamified TripAdvisor website and its Facebook enabled gamification app are used as the specific context of the study. Findings from a survey conducted on TripAdvisor users provide useful practical and theoretical implications to gamification designers and researchers alike on how game mechanics can be designed for enhancing the users' motivation, flow, task involvement and engagement with the 'play' tasks, and so, increasing the gamification's effectiveness.

카카오톡, 페이스북 등의 소셜 네트워크 서비스(Social Network Service: SNS)가 발전함에 따라 이를 기반으로 하는 소셜 네트워크 게임(Social Network Game: SNG)이 지인과 함께 가볍게 즐길 수 있다는 장점을 내세워 유저들로부터 많은 호응을 얻고 있다. 특히 SNG가 갖는 장점은 언제 어디서나 즐길 수 있는 스마트폰 앱에 접목되면서 그 효과가 극대화되고 있다. 이에 많은 개발사들이 앞다투어 SNG 개발에 참여를 하고 있는 상황이지만 다양한 SNS 서비스 플랫폼에 비해 SNG 개발을 위한 공개 엔진은 없는 상황이다. 본 논문에서는 다양한 SNS 플랫폼을 통해 공통으로 사용할 수 있는 통합 관리 소셜 네트워크 엔진을 개발하는 과정과 구현된 엔진을 사용하여 디바이스를 통한 그래픽 출력 성능을 실험하였으며, 실험 결과 기존의 SNG와의 속도차이가 없음을 보여 주어 게임 구현하기에 충분함을 입증하였다.

This study makes a proposal about Flash mobile game applications using Adobe AIR. In developing a mobile game, the developer programs in Flash ActionScript, and distributes and publishes the program using Adobe AIR so that the game can be played on an Android mobile device. In order to run the game, the player downloads and installs Android Adobe AIR onto the mobile device and sets up the published app. This study designed and implemented a mobile game application and showed that a mobile game is executed on a smart phone. This outcome may be applicable to various genres of apps. Moreover, this study analyzed the trends of mobile games, focusing on their genres and characteristics, and according to the results, most of them were mobile games using Kakao Talk. The analysis results also showed that the popularity ranking of games varied little among sites.

With the recent increase of the number of mobile game users, the side effects such as the manipulation of game points, levels and game speed and payment fraud are emerging. Especially, the emulators which make it possible for mobile applications to run on PC is a great threat to mobile game security since debugging specific game application or automating the game playing can be done easier with them. Therefore, we research the efficient ways to detect widely used Android Emulators such as BlueStacks, GenyMotion, Andy, YouWave and ARC Welder from the perspective of client(app), game server and network to reduce threat to mobile game security.

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.

In this paper, in order to encourage the user's exercise, we presented an exercise goal that considers the user's weight and exercise state, and dealt with a study on an app that gives a goal using GPS information. Unlike the vague numbers and times suggested in the existing app, it is presented specifically with the surrounding buildings or structures using GPS information. In addition, to use competitive psychology to exercise encouragement, it shows the movement information of people connected to the app and allows users to use the competitive psychology to get the effect of exercising many people. The app creates coordinates of major buildings and sets markings using the Naver Map SDK location information to present specific targets. It is easy for users to get bored if they give a goal every time, and the boredom that the user feels decreases the interest in the exercise. In order to not to lose interest in athletic interest. the app switches to game mode and give a light goal that doesn't matter user's weight or exercise status, and rewards user for achieving the suggested goals. Game mode is added to app that connects a person's will to practice. It adds fun elements to create interest, and uses competitiveness to help you live a healthy life with a steady workout. Technically, to improve the accuracy of smart-phone map display using GPS and the tilt processing was to be able to display the exact location.
