Purpose Research purpose is extraction of the factors affecting game flow and satisfaction in mobile game. Design/methodology/approach In mobile game, the factors affecting game flow were classified into three parts: mobile game platform characteristics, user cognition characteristics, and user individual characteristics through previous studies for existing online game and mobile game. In the research we extracted the factors as follows: the connectivity, usability, network speed, pleasure, service quality, relatedness, proficiency, self-fulfillment, early adopter tendency, and competitive spirit. Using the factors, we established research model and tested hypotheses empirically. This survey was conducted five months targeting from teenagers to fifties with mobile game experience. The questionnaire items were reconstructed according to the questionnaires of the present study or those newly developed by the game experts and total 56 items in the literature of Internet game, smartphone game, and mobile game based on the existing literature study respectively. Findings According to the analysis result, this study showed that ease of use, enjoyment, self - fulfillment and competitive spirit had a significant influence on user flow and also that service quality, proficiency and competitive spirit had a significant influence on user satisfaction in mobile games.

Currently the mobile augmented reality does not require supplemental hardware, such as markers like specific images or depth cameras, in order to acquire 3D environment information. This allows for increased accessibility and usability for the general user, and also broadened scope of development. The market research enterprise Counterpoint Research predicted that the growth of the augmented reality market will reach 70 trillion Korean Won by 2021. Application developments are also progressing. Wargaming, the developer of the global game World of Tanks, has launched an application that uses AR core at the GDC 2018. Thus, we must prepare for the impending augmented reality market and acquire top class augmented reality technology using 3D environment. This paper outlines the development of a game using AR CORE SDK to acquire 3D environment and Unity 3D game engine to combine camera images and 3D graphics, which all comes together to construct a natural augmented reality.

Many countries and international organizations have carried out rover missions to explore planetary surfaces. Accordingly, the demand for mechatronics education, which is closely related to building exploratory robots, is also steadily increasing. However, due to the complexity in understanding the background information needed for mechatronics, it is hard for pre-college students to study such process. In this study, we suggest an educational platform for mechatronics using a combined robot kit with a spherical robot and a smartphone application. To provide a visual understanding, the dynamic model of the robot is constructed while analyzing the error between actual driving and a simulation, and the educational algorithm of the game and a feedback method are proposed to improve the learning efficacy by considering the user's level of knowledge of mechatronics. We use this educational spherical robot to develop a curling game platform that can impart engineering education even when students lack significant knowledge.

Net neutrality, which has not been a problem, has recently become a problem for ISPs (Internet Service Providers), and their complaints have been paid by domestic platform companies, but overseas global IT companies such as Google and YouTube, generate huge revenues from domestic markets. In this situation, domestic IT companies claim that it is natural to impose more expensive charges or restrict speed on users who generate huge traffic. On the other side, however, the telecommunication network has become an essential public good that is essential to our everyday life, and because it has been given a monopoly position by a private company to efficiently respond to the explosive demand for telecommunication services, It is necessary to provide equal and universal service and fulfill public duty. In this paper, we deal with the network neutrality problem, focusing on the price elasticity between the CP (Contents Provider) and the ISP, rather than the user who is one side of the two-sided market for the already saturated satellites communication market. We present a game model that determines the optimal price for each platform by Nash equilibrium and analyze how the net neutrality affects CP according to the change of exogenous variables through the proposed game model.

As hardware performance rises, game users demand higher computer graphic, more convenient UI(User Interface), faster network, and smarter AI(Artificial Intelligence). At this time, however, AI development is accomplished by a co-development team or only one developer. For that reason, it's hard to verify that AI performance and basic game AI technology is lacking for developing high-level AI. Searching the merits and demerits of existing game AI platforms, we investigate main points to consider when designing game AI platforms in this paper. From this we suggest Darwin, a game platform, based on agent that developers embody AI easily and capable of proposing AI test with module that makes them find strategic position. And then evaluate achievement results through making agent used strategic module that Darwin offers.

Among recent technologies that are applied to game development, virtual reality part is getting much attention for its technological effectiveness in transmitting game processing circumstances in variety that are happening in game world very realistically. In this study we analyze interface for game that is based on a action realization technology and force-feedback technology among technologies for developing virtual reality, in other words, technical analogy on game controller and the positive and negative sides of game controller for each platform. Based on that, more ordinary and effective way to deliver the functions to users in PC game field where application of force-feedback technology is least satisfied. And, Force-Feedback seat has been developed to satisfy the users' needs by using vibration.

In this paper, we suggest a network game system that can support video game based on multi-platform for multi-user video game, Latency occurring from the load fluctuation in realtime network game is overcomed by using an initial delay buffering scheme on client, when a real-fire game is played, and shows that stable play for a game is achieved as the result of the scheme. Also, We suggest a retransmission algorithm based on the history of game commands, and this Algorithm supplement shortcomings for packet loss and pocket error on UDP communication.

This article is a analysis & diagnosis on the shifting of regulation paradigm for arcade game in Korea. Arcade market is decreasing market size after 2006. Arcade platform is characterized by the individuality & PC-based ability. This rapidly changes of the environment are facilitating the gambling in arcade game market. For the protecting the gambling in arcade game market, regulation paradigm needs the shift. To game center & speculative behavior, from game & gambling criteria. The regulation on arcade game in China is a meaningful case, when we make the new paradigm.

This paper introduces a program structure that minimizes the client's business logic by reducing the client's specifications as a way of minimizing the limitations of online game platforms. The objective of this thesis is to design an online game that is based on a 3-tier client/server structure, and thus using this 3-tier structure to ultimately create an online Sutda game that anyone can enjoy. The progression of newly released games is highly based on the mobile market and the number of online games being launched is decreasing. As the mobile game market grows, more and more multi-platform games are being developed and target platforms within online games are greatly diversifying. Through these situations, this thesis minimizes the client's business logic through a 3-tier structure of application-middleware-database, and also proposes an online game client/server that allows three or more users to participate simultaneously through the server.
