A lot of research has been done on image recognition technique for planar images and the performance has also been improved. However, it is difficult to recognize objects in spherical panoramic images or images in special form which are given in various environments because of the spherical distortion given in different form from the planar case. In this paper, we show that the neural network recognition approach can be used for object recognition in spherical image and suggest a method of using cubemap transform in order to increase recognition accuracy in spherical image.

교수-학습 현장에서 일반제시형, 전달형의 자료는 컴퓨터 환경에 익숙한 학생들에게 더 이상의 효과를 주기 어렵다. 따라서 학습자 주도적인 학습자료가 필요하다. 이러한 개념에 바탕을 두어 과학 에듀게임을 설계 및 구현하여 제시하고자 한다. 게임의 주인공이 과학의 4영역인 에너지, 물질, 생명, 지구 각각의 영역을 하나의 무대로 사용하여 활동하고 과학수수께끼를 해결하면서 과학의 이론과 개념에 접근하고 미션을 완수하면서 상위개념을 획득하며 피드백을 통해 습득된 이론을 종합하고 경험의 폭을 넓히는 과정으로 설계하였다. 학습자의 흥미와 집중을 유도하기 위해 실시간 전투 RPG의 형식을 도입하였으며 향후 연구에서 스토리 보강과 각 단원의 세부 맵 보강이 요구된다.

본 논문은 지형중심 게임에서 깊이레벨에 기반한 텍스처 분석 테이블(TAT)을 이용하여 높이에 따라 정의된 지형 객체들을 효율적으로 생성 시킬 수 있는 알고리즘을 제안한다. 기존의 방법에서는 맵에디터 상에서 지형의 텍스처와 지형의 사실적 표현을 위해 나무나 바위 등의 지형 객체를 수작업으로 편집하였는데 제안한 알고리즘을 적용하면 깊이 단계별 최소의 지형 텍스처만을 사용하여 매우 다양한 종류의 지형 텍스처를 생성해 낼 수 있으며, TAT로부터 깊이 정보값을 활용하여 자연-객체들(Natural Object)을 자동으로 생성시킬 수 있다. 이로써 게임 지형을 제작하는데 불필요한 작업량을 줄일 수 있으며, 그만큼 인공-객체들(Artificial Obejct)을 생성하는데 많은 시간을 투입할 수 있다.

본 논문은 요양원·요양병원에 입원한 노인들을 위한 실행능력중심 기능성 스마트 게임기기 및 데이터를 관리할 수 있는 시스템을 개발하고자 한다. 시스템은 증강현실 기반의 스마트맵, 동작 감응형 스마트 스틱, 스마트 명령과 연동하는 로봇, 이러한 게임 콘텐츠로 동작되는 모든 기기에서 나오는 데이터를 수집·관리·분석하는 정보 측정 및 분석 시스템으로 동작되는 시스템을 설계하였다. 이 시스템을 통해 한국이나 일본의 노인병원에서 간절히 필요로 하는 요양보호사 없이 노인들끼리 셀프 진행 가능하고 재미있는 기능성 콘텐츠의 수요를 만족시켜 줄 수 있을 것이다. 또한 치매와 같이 완벽한 치료가 불가능한 질병에도 증상악화를 늦추는 효과가 있으리라 예상한다. 향후 시스템을 개발하여 직접 실험을 하면서 다양한 데이터 수집을 통해 빅데이터로 활용하여 보다 전문적이고 효율적인 재활을 진행할 것이다.

Recently in terrain rendeing, most researches introduce mipmap-based out-of-core methods for handling large sized DEM data which does not fit in main memory of general computer. However, mipmap-based LOD(level-of-detail) methods occur geometric errors which appear in data simplifying the higher LOD level. These geometric errors cause geometric popping effects where LOD level changes when viewpoint moves. In this paper, we propose vertex cohesion map for reducing geometric error. In preprocessing step, we generate vertex cohesion map, which is a texture that stores the vectors. By these vectors, each vertex will be cohered into the position in which the difference of gradient value is bigger than others. Therefore in terrain rendering, using vertex cohesion map can dramatically reduce the geometry popping effects rather than using mipmap.

Battles between players and monsters are considered to be the core issues of RPG games, and they are something that effects the players the most when it comes to thinking whether that particular game is fun or not. Even though MMORPGs have enabled RPGs to get out of the repetitiveness into unlimited possibility of expandability and capability of modification of game plays, essential game play process remains still important - the basic battle between the player and the monsters. In this research, we made a simulator to simulate the process of the battles to estimate results of battles by pre-testing the battles with setting up the experience values of players and monsters using formulae needed for the battle systems at the beginning of game development. It can be utilized at a tester to find out a better configuration of monsters in the maps for better optimization of time and efficiency of the battles to satisfy the game planning.

As the social networking service (SNS), Facebook, and Cyworld, is developing, the social network game and social business commerce based on this service is activated. Especially, the Social Network Game (SNG) is getting explosive interests and it becomes popular, because it is small scale and user can enjoy the game among close friends. The market for this game is getting larger every year, but still it has some limitations in developing the game. Especially, the current game engine is aiming for developing online or console game, and there is no exclusive game engine for developing SNG. Therefore, it takes lots of time for developing SNG with this game engine. In this paper, we described a design and development of the game engine optimized for developing SNG, which not only adapts the main characteristics of the previous game engine, but also considers the specific characteristics of the SNG. The engine also supports map for the simulation game that is the most popular game in SNG, and also provides modules and tools for developing character animation easily. The evaluation standard for the performance of the game engine is the output generation speed of image, text and character. And the results showed reasonable output speed for developing the SNG in generation of image, text, and character.

Virtual reality(VR) is known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence and environment to allow for user interaction. Virtual realities artificially create sensory experience including sight, touch, hearing, and smell. Owing to the use of a single device in most VR contents, user have difficulty in manipulating user interface and game object. And also immersion of the game goes down because they can't see the mouse and keyboard in virtual space. In this paper, we design and implement the chess game to easily and accurately control user interface to improve the immersion in game.

NC Soft will continue to dream of an entertainment innovation world where customers are connected through game and contents. NC Soft images an expansion in entertainment industry which open doors to the future of enjoy break through innovative online game and creative AI & IT technologies, focused on new business opportunities that are solely NC's own. This study starts with the implication on why focusing on exploration innovation and exploitation strategy at the same time in NC Soft is so challenging. NC Soft manages to their online & mobile gaming competencies in the long term and achieves their sustainable growth by incremental innovation (e.g. game planning, game programming, and graphic design). Also, for innovative success, pursuing exploration strategy is essential. NC Soft have built a strategic alliance spanning K-POP, digital contents platform, movie, and animation, sharing the connectivity of entertainment domains with major contents corporations. The findings of this study would also beneficial to entertainment and contents corporation executives and could provide some road-map on managing the dual challenges of exploration and exploitation implementations.

Recently, Massively Multiplayer Online Role-Playing Games (MMORPGs) has become increasingly popular, which continue to increase the number of game player. The volume of the game world also has been extended on a large scale. Existing Map-based distributed server architecture divides the game world into the rectangular regions and allocates the registered player in each region to the server responsible for that region. Players tend to concentrate in certain regions of the game world, which makes some special server overloaded. This paper proposes to change the boundary between servers to solve such a unbalanced load problem. Our proposed method first finds the overloaded server and then searches for its neighboring lightest loaded server to share with the overload evenly. Finally we implemented performance evaluation to demonstrate the efficiency of this approach.
