본 논문에서는 차세대 게임 인터페이스를 활용한 기능성 런닝게임을 제시한다. 게임은 2인용 대결방식으로 개발하였으며, 방식은 다음과 같이 나뉜다. 첫째, 뇌파측정기를 이용하여 사용자1의 감정 변화, 집중력의 강도, 안면의 움직임을 측정한다. 둘째, 모션 캡쳐 장치인 키넥트를 이용하여 사용자2의 달리기, 좌우 방향전환, 점프 등의 모션을 측정한다. 본 게임의 핵심은 사용자의 뇌파 그래프가 실시간으로 게임내의 맵의 형태로 표현되는 것이다. 사용자는 자신의 뇌파가 게임 내의 맵으로 시각화되는 것을 보며 뇌파를 스스로 조절하는 학습능력을 배울 수 있다. 따라서 사용자1은 이러한 기능성 게임을 플레이하면서 뇌의 활성화를 통한 집중력 향상을 꾀할 수 있고, 사용자2는 실제로 달리고 점프하는 동작을 통한 운동능력을 증진하는 효과를 얻을 수 있다.

잠입 액션 게임은 크게 적을 공격해 잠입하거나 적의 시야를 회피하는 두 가지 방식으로 진행된다. 최근의 잠입 액션 게임은 높은 액션의 비중으로 전면대결의 빈도가 높아져 다른 액션게임 장르와의 경계가 흐려졌다. 본 논문에서는 플레이어를 약자의 위치에 두어 액션을 이용한 잠입이 아닌 회피를 이용한 잠입을 주된 특징으로 하는 게임을 제작하고 그 제작과정을 기술한다. 회피를 위한 주요 요소로 빛을 선택해 적의 시야를 차단하여 회피하는 것을 주된 플레이 방법으로 삼았고 액션 요소를 추가하기 위해 다양한 프로토타입을 제작하여 테스터들에게 플레이하도록 하는 플레이 테스트를 거쳤고, 그 결과 제한된 상황에서의 액션이 선택되었으며, 잠입에 영향을 주는 사용자 인테페이스 중 미니맵, 입력 장치가 추가, 수정되었다. 잠입을 이용한 게임 제작 시 결정된 여러 사항들을 살펴보고 그 결정과정의 경험을 기술한다.

This paper studies the distributed energy efficient resource management in the Internet of Things (IoT). Wireless communication networks support the IoT without limitation of distance and location, which significantly impels its development. We study the communication channel and energy management in the wireless communication network supported IoT to improve the ability of connection, communication, share and collaboration, by using the game theory and distributed learning algorithm. First, we formulate an energy efficient neighbor collaborative game model and prove that the proposed game is an exact potential game. Second, we design a distributed energy efficient channel selection learning algorithm to obtain the global optimum in a distributed manner. We prove that the proposed algorithm will asymptotically converge to the global optimum with geometric speed. Finally, we make the simulations to verify the theoretic analysis and the performance of proposed algorithm.

Purpose - This paper explains how free trade agreements (FTAs) work as a building block to achieve global free trade and be better than other trade regimes. Design/methodology - This paper utilizes a trade liberalization game setup. Three countries choose a trade agreement strategy based on a given trade regime. Trade agreement is made only when all member countries agree. The paper evaluates each trade regime concerning FTAs and customs union (CU) by area size of global free trade equilibrium on the technology or demand gap between countries. Findings - FTAs make global free trade easier. In this game, there are two main reasons for failure to reach global free trade. First, a trade regime with FTAs makes non-member face difficulties in refusing trade agreements in the existence of a technology gap than a trade regime without FTAs. Also, a trade regime with FTAs causes it harder to exclude non-members in the existence of a demand gap than a trade regime with only CUs. Therefore, a trade regime with FTAs can work better in reaching global free trade. Originality/value - The concept of "implicit coordination" was used, which assumes that FTA members keep external tariffs for non-members the same as before an FTA. Without this consideration, FTA members lower their tariffs to non-members, and it makes non-member refuse free trade easier. FTA can prevent it sufficiently only with implicit coordination. This makes the trade regime with FTAs more effective to reach global free trade.

In this paper, we investigate the problem of achieving global optimization for distributed carrier aggregation (CA) in small cell networks, using a game theoretic solution. To cope with the local interference and the distinct cost of intra-band and inter-band CA, we propose a non-cooperation game which is proved as an exact potential game. Furthermore, we propose a spatial adaptive play learning algorithm with heterogeneous learning parameters to converge towards NE of the game. In this algorithm, heterogeneous learning parameters are introduced to accelerate the convergence speed. It is shown that with the proposed game-theoretic approach, global optimization is achieved with local information exchange. Simulation results validate the effectivity of the proposed game-theoretic CA approach.

This study analyzes on localization plans to successfully enter ASEAN market more rapidly growing than over-saturated the Asian or North American mobile game markets based on the Vietnamese market. Vietnamese smartphone market is the fastest growing in ASEAN based on its young aged population of average 28.2 year-old and low 3G service charges. Considering one of the most common activities through smartphones is the mobile game, the smartphone demand increase can be forecasted to be based on the growth of Vietnamese game market. Global strategies for exporting products to the global market can be classified into 'standardization' and 'localization'. From among these, Korean game companies are making profits by localization plan. But the Vietnamese mobile game market still has entry barriers. Therefore, this study is to contribute to Korean mobile game companies' localization plans for the Vietnamese market by finding and supplementing limits of the Vietnamese mobile game market based on literatures and statistics materials.

Recently, global environmental problems have become serious due to human economic activities. Therefore, in order to build a sustainable society in which human economic activities coexist with nature, it is important to promote and enhance environmental education. As a preceding study, a board and computer game of "Ecopoly," which is the game for education on global environmental problems, were developed. This study further aims to develop algorithms which make decisions in Ecopoly, to automate decision-makings of opponents using the algorithms, and to develop the environmental educational game "Ecopoly V" which enables self-learning. In order to develop the algorithms, the board game of Ecopoly was played, and each player's decision-makings at the all points at which players make a decision were observed and analyzed. From the analyses, it became clear that the decision-makings were distinguished by 3 characteristics; Ecology type, Economy type, and Balance type. Based on the characteristics, the factors and standard values of each decision-making were made clear. Algorithms were developed based on the factors and standard values. Ecopoly V was developed by incorporating the algorithms into the computer game of Ecopoly. Experimental testing of the game was conducted and the validity of the game was verified.

Tangram game consists of seven pieces of polygons such as triangle, square, and parallelogram. Typical methods of image processing for object recognition may suffer from the existence of side thickness and shadow of the puzzle pieces that are dependent on the pose of 3D-shaped puzzle pieces and the direction of light sources. In this paper, we propose an image processing method that recognizes simple convex polygon-shaped objects irrespective of thickness and pose of puzzle objects. Our key algorithm to remove the thick side of piece of puzzle objects is based on morphological operations followed by logical operations with edge image and background image. By using the proposed object recognition method, we are able to implement a stable tangram game applications designed for tablet computers with front camera. As the experimental results, recognition rate is about 86 percent and recognition time is about 1ms on average. It shows the proposed algorithm is fast and accurate to recognize tangram blocks.
