Home Entertainment system is recently being offered by Home Theater & Smart TV with contents service. Also, console game is being played in the media like in TV. The usage of 4D as the main technology in entertainment industry has mostly been limited in Theme Park, Amuse Park, Theater, and contents for Movie and Animation. Some simulation systems for game has been developed but they were made mostly by using electric or hydraulic motion system which cause high power consumption and have a restriction of place for install. The paper is attempted to build Home Entertainment system which makes users feel realistic contents by developing 4D systems for Home Entertainment rather than before. 4D control S/W in which user can insert and edit 4D effects on contents of all areas such as game, movie, and broadcasting is developed. Also, built-in pneumatic cylinder in 4D system which can be easily controlled and managed in home is developed.

As the complexity of a 3D game is increased by various factors of the game scenario, it has a problem for controlling the interrelation of the game objects. Therefore, a game system has a necessity of the coordination of the responses of the game objects. Also, it is necessary to control the behaviors of animations of the game objects in terms of the game scenario. To produce realistic game simulations, a system has to include a structure for designing the interactions among the game objects. This paper presents a method that designs the dynamic control mechanism for the interaction of the game objects in the game scenario. For the method, we suggest a game agent system as a framework that is based on intelligent agents who can make decisions using specific rules. Game agent systems are used in order to manage environment data, to simulate the game objects, to control interactions among game objects, and to support visual authoring interface that ran define a various interrelations of the game objects. These techniques can process the autonomy level of the game objects and the associated collision avoidance method, etc. Also, it is possible to make the coherent decision-making ability of the game objects about a change of the scene. In this paper, the rule-based behavior control was designed to guide the simulation of the game objects. The rules are pre-defined by the user using visual interface for designing their interaction. The Agent State Decision Network, which is composed of the visual elements, is able to pass the information and infers the current state of the game objects. All of such methods can monitor and check a variation of motion state between game objects in real time. Finally, we present a validation of the control method together with a simple case-study example. In this paper, we design and implement the supervised classification systems for high resolution satellite images. The systems support various interfaces and statistical data of training samples so that we can select the most effective training data. In addition, the efficient extension of new classification algorithms and satellite image formats are applied easily through the modularized systems. The classifiers are considered the characteristics of spectral bands from the selected training data. They provide various supervised classification algorithms which include Parallelepiped, Minimum distance, Mahalanobis distance, Maximum likelihood and Fuzzy theory. We used IKONOS images for the input and verified the systems for the classification of high resolution satellite images.

We propose an object recognition system and experiential game contents using Kinect to maximize object recognition rate by utilizing underwater robots. we implement an ice hockey game based on object-aware interactive contents to validate the excellence of the proposed system. The object recognition system, which is a preprocessor module, is composed based on Kinect and OpenCV. Network sockets are utilized for object recognition communications between C/S. The problem of existing research, degradation of object recognition at long distance, is solved by combining the system development method suggested in the study. As a result of the performance evaluation, the underwater robot object recognized all target objects (90.49%) with 80% of accuracy from a 2m distance, revealing 42.46% of F-Measure. From a 2.5m distance, it recognized 82.87% of the target objects with 60.5% of accuracy, showing 34.96% of F-Measure. Finally, it recognized 98.50% of target objects with 59.4% of accuracy from a 3m distance, showing 37.04% of F-measure.

본 논문에서는 복잡한 랜덤 배경 하에서 위치하고 있는 게임 플레이어의 얼굴 영상을 스테레오 매칭을 이용하여 배경과 분리하여 추출할 수 있는 방법에 대하여 기술한다. 사람과의 상호 작용이 필요한 게임일수록 사람의 동작이나 각 부위에 대한 인식이 필요하다. 이 방법은 게임 이외에도 보안 시스템, 의류 시뮬레이션, 3D 모델링 그리고 로보틱스와 같은 분야에 적용될 수 있다. 스테레오 매칭에 관해서는 많은 연구가 있어왔으며, 기본적으로 영역기반 방법과 특징기반 방법으로 분류될 수 있다. 본 논문의 제안 방법 에서는 영역기반 방법으로 처리를 시작하고, 다단계 크기의 윈도우를 적용하여 물체의 경계선을 찾는 작업을 진행한다. 각 윈도우 크기에 대하여 유사성 커브가 생성되며, 이 값은 물체의 경계선을 판별하는 특징으로 사용된다. 전단계에서 생성된 코어스(coarse) 영역은 유사성 커브 방식에 의하여 머지 작업을 거치며, 최종적으로 대상 물체의 영상을 추출하게 된다.

3D 입체영상의 후반작업에서 색보정은 전체의 화질에 영향을 미치는 중요한 과정이다. 기존의 색보정 방법들은 좌, 우영상 중에서 히스토그램을 바탕으로하여 어느 한쪽을 기준으로 일치성을 강화하는 처리를 한다. 히스토그램을 기반으로 색보정을 하는 경우, 충분한 색온도 변환이 이루어 지지 않는 단점이 있으며, 본 논문에서는 히스토그램을 사용하지 않고 색온도 변환을 중심으로 색보정하는 방법을 제안한다.

With the consistent development of the 3D application technique, visuals are available at more realistic quality and are utilized in many applications like game. In particular, interacting with 3D objects in virtual environments, 3D graphics have led to a substantial development in the augmented reality. This study proposes a 3D user interface to control objects in 3D space through virtual two-view method using only one camera. To do so, homography matrix including transformation information between arbitrary two positions of camera is calculated and 3D coordinates are reconstructed by employing the 2D hand coordinates derived from the single camera, homography matrix and projection matrix of camera. This method will result in more accurate and quick 3D information. This approach may be advantageous with respect to the reduced amount of calculation needed for using one camera rather than two and may be effective at the same time for real-time processes while it is economically efficient.

Recently, many researches about making more comfortable input device based on gaze detection technology have been done in human computer interface. However, the system cost becomes high due to the complicated hardware and there is difficulty to use the gaze detection system due to the complicated user calibration procedure. In this paper, we propose a new gaze detection method based on the 2D analysis and a simple user calibration. Our method used a small USB (Universal Serial Bus) camera attached on a HMD (Head-Mounted Display), hot-mirror and IR (Infra-Red) light illuminator. Because the HMD is moved according to user's facial movement, we can implement the gaze detection system of which performance is not affected by facial movement. In addition, we apply our gaze detection system to 3D first person shooting game. From that, the gaze direction of game character is controlled by our gaze detection method and it can target the enemy character and shoot, which can increase the immersion and interest of game. Experimental results showed that the game and gaze detection system could be operated at real-time speed in one desktop computer and we could obtain the gaze detection accuracy of 0.88 degrees. In addition, we could know our gaze detection technology could replace the conventional mouse in the 3D first person shooting game.

1992년 id Software가 최초의 3차원 게임인 Wolfenstein 3D(그림 1)를 선보인 이래, 3차원 게임은 게임 시장에서 주류의 자리를 차지하게 되었다. 저사양의 하드웨어에서 구동되는 모바일 게임을 제외하고는 현재 대부분의 게임이 3차원으로 제작된다고 보아도 무방할 것이다. 이 같은 시장 수요에 부응하여 다수의 3차원 렌더링 엔진이 개발되었는데, 대표적인 것으로는 id Software의 Doom Ⅲ, Criterion의 Renderware, Epic Games의 Unreal Ⅱ 및 Ⅲ, Intrinsic의 Alchemy, NDL의 GameBryo 등이 있다.

It was hypothesized that mobile 3D provide the sense of presence in different quantity and quality aspects in virtual reality. And it was supposed that the construction of presence involves various levels and dimensions. The factors of mobile 3D game are divided into 4 super-factors; condition factor, interface factor, attention factor, feedback factor that resulted into 20 sub-factors resulted from the factor analysis. Our primary goal is the development of valid Mobile 3D presence scale, and to find out the factor structure of the scale.
