  • In these days the virtual reality technology has been applied to treat such an anxiety disorders. And also a medical doctor can diagnose the patient in distance with the telemedicine system. In this thesis, an telemedicine assistant system for treatment of acrophobia using biomedical signals and virtual reality technique is proposed. I made two virtual reality simulations for treatment of acrophobia and telemedicine system for communication between doctor and patient using personal computer. Multimedia conference service, online questionary, signal transfer system are needed to configure such system. Virtual reality simulation system that composed of position sensor, head mount display, and audio system, is also included in this telemedicine system. I added virtual environment update system to this virtual reality telemedicine system for treatment of acrophobia. With this virtual environment update system, the doctors can change virtual reality simulation stage based on the status of each patient and symptom of phobia. We will apply this system to the acrophobia patient in distance and be able to offer better medical treatment for mental illness in near future.

  • In this paper planed Virtual Reality user interface that recently hot issue using MVLS(Multipurpose Visual Language System). Proposed system is planed for more with ease approach new type environment system. The point of this system is for more few the number of time of act to get want to result. That is easy build for Virtual Reality environment system that user so far, who did not experience. Also too, application to the environment through Multipurpose Visual Language System based, can be required to increase the case of user of existing applications, not only a simple application infrastructure Virtual Reality. This has the advantage of being able to under Virtual Reality condition the environment for the use of a wide range of applications such as view TV, video and other contents. By using the proposed system, the experience in virtual realities that have not felt during the general public to be able to easily and quickly, virtual reality or 3D Expected to can one step closer to the needs of general and industry.

  • A nuclear Power Plant is composed of a number of mechanical components. Maintaining the integrity of these components is one of the most critical issues in nuclear industry. In order to evaluate the integrity of these mechanical components, a lot of data are required including inspection data, geometrical data, material properties, etc. Therefore, an effective database system is essential to manage the integrity of nuclear power plant. For this purpose, an internet based virtual reality environment and web database system was proposed. The developed virtual reality environment provides realistic geometrical configurations of mechanical components using VRML (Virtual Reality Modeling Language). The virtual reality environment was linked with the web database, which can manage the required data for the integrity evaluation. The proposed system is able to share the information regarding the integrity evaluation through internet, and thus, will be suitable for an integrated system for the maintenance of mechanical components.

  • VR (Virtual reality) technologies have given engineers the ability to design, test, and evaluate engineering systems in a virtual environment. The virtual plant is the highlight of the application of the VR technology to plant engineering. Plant design, maintenance, control, management, operation are integrated in the virtual plant. The VR monitoring system including the concept of the virtual plant is developed to replace a current control room that has number of gages and warning lamps in two-dimensional panels which shows the operating status of a plant. The operating status of the plant is displayed in the VR monitoring system through the realistic computer graphics. Sophisticated, realistic and prompt control becomes possible. The VR monitoring system consists of advanced visualization, walk-through simulation and navigation. In the virtual environment, a user can navigate and interact with each component of a plant. In addition, the user can access the information by just clicking interesting component. The VR monitoring system is operated with various modules, such as (1) virtual plant constructed with Graphic Management System (GMS), (2) Touch & Tell System, and (3) Equipment DB System of Part. In order to confirm the usefulness of the VR monitoring system, a pilot gas plant which is currently being used for plant operator training is taken as application. The end of the paper gives an outlook on the future work and a brief conclusion.

  • Three-dimensional(3D) integral imaging system which can be used in a virtual reality system is proposed. The proposed system uses a new image mapping algorithm which can achieve the real time processing, which is indispensable for the virtual reality system. 3D images generated by the advanced graphic software such as OpenGL API can be directly used without complex adaptation. Therefore, the computer-generated integral imaging system using the proposed mapping algorithm can be successfully applied to virtual reality.

  • 현대사회는 정보화 사회로 모든 사람들이 빠르고 정확한 정보를 필요로 하고 있으며 이러한 정보를 신속히 받아들여 생활에 활용하기를 원한다. 또한 현실의 한정된 공간과 시간에 구애받지 않고 보다 자유로이 상상의 세계를 현실과 같이 경험하고자 한다. 디자인은 '무'에서 '유'를 만들어내는 창조적인 행위로써 '가상'(Virtual)적인 의미를 내포하고 있다. 따라서 디자인은 상상 속에 존재하는 형태나 이미지를 실제로 재현하기 위한 '가상의 현실화'(Reality of Virtuality)작업이라 말할 수 있다. 디자인 분야는 과거로부터 현재까지 컴퓨터 응용 방법들이 많이 활용되었다. 컴퓨터의 발전과 함께 디자인 과정 또한 시간적으로나 방법적으로 간편화되었고 또한 효율적으로 발전하였는데 이러한 의미에서 컴퓨터는 디자인에 지대한 영향을 미치는 하드웨어임에는 틀림이 없다. 이번 연구는 환경디자인(Environmental Design)에 적용되고 있는 컴퓨터 활용 방법에 대해 알아보고 단순한 활용에서 적극적이고 체계적인 방법으로의 모색을 통해 현실감(Presence)을 극대화하여 이를 설계에 적극적으로 도입하는 방안에 대하여 연구하고자 한다. 현재 연구가 활발히 진행되고 있는 가상현실 시스템(Virtual Reality System)을 환경디자인(Environmental Design)분야에 폭 넓게 활용하여 수준 높은 설계를 제공하고 모의실험을 통한 현실감의 극대화를 도출하고자 하며 앞으로 가상현실 시스템(Virtual Reality System)과 같은 다양한 컴퓨터 시뮬레이션 기법들이 환경디자인에 적극적으로 도입될 전망이다.

  • In this study, the factors affecting reality aspect of virtual reality system were identified through Quality Function Deployment. The influence of some selected factors was evaluated in simulated performance test. It was shown that the factor of whether user can break through the objects in virtual space is the most sensitive to performance, followed by the factors of rotation angle and movement step. Also, the results implied that as more referents were provided to user, feeling of reality was enhanced.

  • This paper presents an attempt to develop a visual programming language-based 3D virtual reality authoring tool intended to compose virtual interior space. The rapid development of digital technology and the wide spread of the Intenet have expanded the different uses of virtual reality in a number of applications ranging from interior design to building maintenance. In particular, the construction of cyber spaces based on existing interior spaces is becoming increasingly important. Current research, however, remains at the level of converting 3D models into virtual reality models, despite practitioners' needs for structural space models. Moreover, commercial tools to build virtual reality space have the disadvantage of targeting people who have professional knowledge of computer programs and computer graphics. Accordingly, the 3D virtual reality authoring tool developed in this research - called the VESL system - enables virtual and structural space to be easily composed using intuitive and interactive visual interfaces, which are based on visual programming techniques. The VESL system also provides an XML based semantic description of interior space, to be used to describe interior space information. We anticipate that the virtual reality spaces composed by this system will be of considerable use in the fields of architecture and interior design. Further research issues identified at the end of the research include developing a converter/filter for transforming Internet virtual reality standard language, or VRML, and evaluating the application of the system for practical use.

  • Virtual reality can be applied well to product design and evaluation. A virtual design evaluation system for an automobile cabin was implemented on a desk-top virtual environment system. It has two frontal seats, a dashboard, a steering wheel, and various displays/controllers. Users can interact with these components as they do that with real ones. To verify the effectiveness of the virtual design evaluation system, 17 subjects participated in the evaluation procedure. The evaluation result showed that the stereoscopic vision enhanced the subjective reality of the virtual automobile cabin. Graphic details, design, and time lag were also related to the subjective feel for reality.
