컴퓨터에서 생성된 시뮬레이션의 결과는 일련의 가시화(VIsualization)라는 과정을 거치면서 컴퓨터 그래픽스 기술이 적용됨으로써 인간이 해석하기 쉬운 형태로 변형되게 된다. 연구자가 직관적으로 이해하기 어려운 수치의 나열로 구성돼 있던 시뮬레이션 데이터가 보다 쉽게 이해하고 분석할 수 있게 되는 것이다. 그런데, 최근에는 고성능 컴퓨터(HPC)의 발달로 인해 시뮬레이션 데이터의 크기가 점점 더 증가하는 추세에 있으며, 데이터의 크기가 기가바이트를 넘어 테라바이트에 이르는 경우도 흔해지고 있다. 기존의 가시화 시스템에서 복잡해진 가시화 데이터를 면밀하게 해석하기에는 많은 제약이 따르며, 그로 인해 고해상도 디스플레이 장치나 몰입형 가상현실 장치의 도입은 필연적일 수밖에 없다. 특히 현 시점에서 클러스터 시스템을 이용한 고해상도의 디스플레이 장치에서 사용자와 상호작용할 수 있는 인터페이스를 제공하는 방법은 가상현실 환경을 적절히 활용하는 것이 거의 유일하다 할 수 있겠다. 본 논문에서는 시뮬레이션 데이터, 특히 로터 동역학 분야의 시뮬레이션 데이터를 가상현실 환경에서 가시화하고 제어하는데 필요한 프레임워크와 인터페이스를 소개할 것이다. 이 프레임워크는 가상현실 환경에서 로터 동역학 분야의 시뮬레이션 데이터와의 실시간 상호작용을 통한 해석을 수행하는데 필요한 기반환경을 제공할 것이다.

분산 가상 환경은 고속 통신망과 컴퓨팅 환경의 고급화로 응용 분야를 넓혀 가고 있으며, 보다 현실감 있는 상호작용으로 인해 만남과 대화, 협력 작업, 상거래, 오락 등의 인간의 사회적 활동을 지원하는 새로운 수단으로 자리잡고 있다. 가상 도시와 같은 대규모의 가상 환경에는 공원이나 거리, 건물의 로비 등과 같은 개방적인 공간과 사무실과 같은 업무 공간, 그리고 쇼핑몰과 같은 상거래 공간들이 공존하게 되므로 접근 제어와 보안이 보다 중요한 문제로 대두된다. 따라서, 이 논문에서는 분산 가상 환경내의 모든 사물들을 객체로 인식하고, 객체에 대한 역할을 기반으로 하는 접근 제어 모델을 제안하고, 제안한 모델을 기반으로 접근 제어 관리자를 설계하였다. 설계된 접근 제어 관리자는 가상 환경내 공간의 객체 뿐만 아니라 공간 자체도 하나의 객체로 인식하여 접근 제어를 하였다. 또한, 대규모 공간에서의 중요한 특징인 관리의 용이성과 동적인 변경을 가능하게 하기 위해, 역할을 기반으로 참여자와 객체를 연결하고, 객체가 갖고 있는 행위까지를 제어할 수 있었다.

Due to the advent of virtual reality, the past communication method using images and video through the expansion into three-dimensional space has been provided more realistic and seamless interaction environment. Unlike reality, virtual reality is under a full human control and due to this benefit can be used as a substitute for reality therefore medicine and healthcare area has attracted attention in the prevention and treatment of dementia utilizing virtual reality. The research provided in this paper is aimed to design a virtual reality-based mild cognitive impairment prevention training system, focusing on the Symptoms of Alzheimer's precursor, mild cognitive impairment.

Humanism connotes dignity and esteem with the essential idea of human and more human. This paper has conducted a inquiry of the understanding about human and humanism represented by visual image of film. Especially, this study investigated the way to adhere to reflective attitude about human and society. It is based on theoretical discussion of formalism and auteurism and analyzed the way of constructing time-space structure of (by Lars von Trier) which is known the typical formalism film. According to the findings, appeared to appropriate the ocularcentrism aesthetic to film form and give the self-regulation to definite the idea of film art through picturesque imagination of dramatic stage. Such a result means that it converts the filmic time-space to the virtual things and practicalize the classification of the ethical doctrine of innate goodness and innate sin of human and the definition of humanism. Also it means formalism film overturns the existing institutional mode of representation.

The objectives of this study is to develop an adaptable digital wall model whose color can be changed dynamically according to the identified emotional state of a user. This study addresses how to capture a specific user's emotion through the web and use it for modifying VR model mainly for color adaptation. This adaptation process of a VR model consists of three phases: 1) identification of the user's emotional state projected onto the list of emotional keywords 2) translation of those captured emotional keywords into a pertinent set of color coordinations, and finally, 3) automated color adaptation process for the given model. This process derives an on-line viewer's emotional state, which can be utilized to find a new color scheme reflecting the identified emotion.

Recently there are lots of concerning on robot agent system working for itself with the trends of the research of bio-mimetic system and intelligent Therefore it is necessary to develop more humanized interface system from communicating with the robot agent. In this paper a virtual 3D interface system is proposed based on Internet for remote controlling and monitoring of robot agent. The proposed system is constructed as manager-agent model and a man can order a job at the 3D virtual interface environment of the manager located remotely Then the robot agent detects a 3D profile data from a range finder automatically and the robot moves the object to the new position in real space. The proposed system supports a advanced interface displaying virtual 3D graphics and real moving images and which makes it possible one to manage the robot agent more conveniently.

The future of human life is expected to be innovative by increasing social, economic, political and personal, including all areas of life across the multi-disciplinary skills. Particularly, in the field of robotics and next-generation games with robots, by multidisciplinary contributions and interaction, convergence between technology is expected to accelerate more and more. The purpose of this study is that by new interface model beyond the technical limitations of the "human-robot interface technology," until now and time and spatial constraints and through fusion of various modalities which existing human-robot interface technologies can't have, the research of more reliable and easy free "human-robot interface technology". This is the research of robot game system which develop and utilizing real time synchronization engine linking between biped humanoid robot and the behavior of the position value of mobile device screen's 3D content (contents), robot (virtual robots), the wireless protocol for sending and receiving (Protocol) mutual information and development of a teaching program of "Direct Teaching & Play" by the study for effective teaching.

The purpose of this research is to develop a virtual reality system which enables to actually experience the virtual reality through the visual sense of human. TSS was applied in tracing the movement of moving picture in this research. By applying TSS, it was possible to calculate multiple motion vectors from moving picture, and then camera's motion parameters were obtained by utilizing the relationship between the motion vectors. For the purpose of experiencing the virtual reality by synchronizing the camera's accelerated velocity and the simulator's movements, the relationship between the value of camera's accelerated velocity and the simulator's movements was analyzed and its result was applied to the neutral network training. It has been proved that the proposed virtual reality immersion system in this dissertation can dynamically control the movements of moving picture and can also operate the simulator quite similarly to the real movements of moving picture.
