This study is analyzed by comparing the evaluation of usability and study achievement for simulation learning based on Web 3D and VR and it is aimed to verify the characteristics of the virtual reality through a difference in studying effect between each learning method. Therefore, this study is analyzed by comparing the evaluation of usability and study achievement for the CSI Forensics Lab simulation content that has been developed in two learning methods for scientific experiments of DNA analysis with the 75 university students of Life Science as a population(Web 3D=37, VR=38). The results of the study, in usability of user task action, exploratory and navigation, Web 3D simulation learning was positive in a significant difference, but in usability of satisfaction, VR simulation learning was positive in a significant difference. In study achievement, Web 3D simulation learning was slightly higher but did not confirm the significant differences between both of learning.

To propose the construction of architectural interior design and communication using graphic, web3D, it was studied the kind and character of various representation methods that can be embodied in an architectural interior design on the web, and looks into whether these ways can be adapted to an architectural interior design process. Especially, the use of the current techniques on graphic and CAD data give the most suitable effect by using the integrated data such as vector animation, an interaction of object VR(Virtual Reality), a high quality of panorama VR, and data treatment and its interaction of drawing of cad data. As a result, the single data format shows not only one image representation but also a stream of continuous operation through a change into another format. But this desired study expects that another next studies will go on interaction and integration of digital format with increase of transmission speed expected in the future, and a digital model and its practical methods.

In this paper, we implemented a web-based 3D virtual pottery gallery Using VR authoring tools. With this system, we expect to cause learning motives and Provide more realistic and interactive learning space. Out system was implemented by making panorama images and 3D object modules using Photo Vista. Object Modeler and Reality Studio. Users can connect to this web site(http://artstory.x-y.net), rotate a pottery panoramically, and zoom it in or out. We designed this virtual gallery can have beneficial influence on students' aesthetic aspects through realistic work appreciations in their art education processes.

Recently, the Virtual Reality(VR) became one of the most powerful tools in making media files. In the field of engineering, while it is increasing to use 3D CAD model in the process of design to manufacturing, the VR is not popular in comparison with media business. XVL(eXtensible Virtual Reality Markup Language) is one of XML(eXtensible Markup Language) which is a standard web media language. XVL provides the connection between 3D CAD data and virtual reality, and it can be easily published through internet for the engineering purpose. In this study, a web based VR model for major components in a nuclear power plant has been developed by using XVL and corresponding 3D CAD data. The proposed model is expected to be used in the engineering field to cooperate among experts, and also, it will provide more plausible explanation to ordinary people.

The Internet is encountering a new turning point owing to the raising Web 2.0. A user Just receives the information and service provided by a service provider in the existing web 2.0, but a user can create a new service for himself using an application program and data provided in web 2.0. The digital content market is producing a new service according to Web 2.0. The specific service among them is User Created Contents(UCC) and it is leading to the participation and interesting of user SecondLife also which is the type as Social Network Service(SNS) and VR, is placing as a new service type. This paper defines Web 2.0 environment and classifies as UCC, SNS and Virtual Reality(VR) and defines a variety services shown in new environment. It also analyzes shortcomings and then prospect a new type of service which will be shown in the future.

This study aims to propose the exhibition contents by utilizing the technique for 3D VR using the presidential archives that are provided on the web-site. Especially, this study proposed requirements and a method to develop exhibition contents based on 3D VR technique. To accomplish it, this study analyzed literature review and cases of the online exhibition in presidential archives and then classified contents to find out how to apply 3D VR for exhibition contents effectively. With the results of the analysis, this study selected the type of records and proposed the effective 3D VR model as displaying contents. Then, this study developed an implementation case.

This purpose of this study was to investigate learning effects of Web-based 3-dimensional VR(Virtual Reality) program and a 2-dimensional HTML program, and to find out interaction effects between the types of web-based instruction program(3-dimensional VR program and 2-dimensional HTML program) and the levels of spatial perception of the learners on learning achievement and satisfaction in an educational aspect. In conclusion, there was a significant difference in learning achievement and general satisfaction of the learners between the group providing 3-dimensional VR program and the group 2-dimensional HTML program(F=4.85, p<.05). The 3-dimensional VR program was found to be more effective. And, there was a significant interaction effect in learning achievement effects between the types of web-based instruction program and the level of spatial perception of the learners(F=32.48, p<.05).

기존 가상현실(Virtual reality) 콘텐츠는 제작인 완료된 상태로 제공되기 때문에 법 개정 및 교육 커리큘럼 변화에 능동적으로 대응하지 못한다. 따라서 VR 콘텐츠 제작시 편집이 가능한 툴과 편집된 VR 콘텐츠가 바로 실행되는 편집 도구를 구현한다면 훈련 내역의 변경이 지속적으로 발생되는 VR 콘텐츠에 대안책이 될 것이다. 따라서 이를 해결하기 위해 VR 콘텐츠의 주요 생성 및 생성된 시나리오의 세부 씬(Scene) 구성을 사용자가 직접 생성하는 편집 도구를 구현하고 VR 장치가 없는 운용 환경에서도 실행이 가능 하도록 Web 기반의 편집 도구를 개발하여 VR 콘텐츠의 편집 및 실행 시 동시처리가 가능하도록 편집 도구를 개발하였다.

학술대회에 발표된 논문은 이동형 저장장치 혹은 학회 홈페이지를 통해 배포된다. 이용자가 저자의 설명 없이 배포된 논문만으로는 내용을 이해하는 데에 한계가 있다. 이러한 한계를 해결하고 더 나아가 언제 어디서든 설명을 들을 수 있는 환경을 제공하기 위해 웹 기반으로 MPEG-DASH 기반의 학술대회 중계용 가상 포스터세션 서비스를 제안한다. 제안하는 서비스는 포스터 발표자의 영상을 가상공간에 배치하고 이를 MPEG-DASH 기반으로 전송한다. 가상공간은 구글의 WebVR API을 응용해 구현하여 별도의 프로그램 설치 없이 웹 기반으로 이용할 수 있으며 MPEG-DASH 기반의 전송을 통해 효율적인 대역폭 활용이 가능하다. 본 서비스를 통해 논문의 내용을 효과적으로 전달할 수 있을 것이며 새로운 학술대회의 패러다임 제시가 가능할 것으로 예상한다.
