Digital Koguryo is a virtual reality reconstruction of the Koguryo mural tumulus, Anak No. 3, designed for an interactive educational gaming and learning environment. Digital Koguryo aims at not only developing a digital reconstruction of cultural heritage but also helping young students learn the living style and the custom of Koguryo Kingdom while playing the game environment. This paper describes the digital restoration process of Koguryo mural paintings and 3D structure, as well as the construction of educational virtual environment designed to get more user's interests. It then discusses a few design issues learned from the development and the public demonstration. Finally, it will present the future research directions to improve the users' immersion.

Development and implementation of virtual training contents has been increasing along with the emphasis on the experience and practice in engineering education. Virtual training makes repeatable sessions possible within safe learning environment which is very similar with real work place. This feature is very helpful to learners when they manipulate real machines back at work after studying with the virtual training content. The purpose of this study is to develop "Total Station and GPSS surveying" virtual training content focusing on both theory and surveying practice within various circumstances and to explore learners experience. Results show high interest, immersion, perceived learning effectiveness, and satisfaction to the content.

As the computer is popularized in individual and society, it is using in a many of area. In particular, there are many materials to learn a science knowledge using multimedia through computer. Many of them are web-based learning materials, which are developed by Java or Flash. Since the technology of the representation, storage, com-putation and communication in computer make progress, the environment of education is also developed. Especially, the internet and VR technology will cause the education to change. A key feature of VR is real-time interactivity, in that the computer is able to detect student input and instantaneously modify the virtual world. It is reported that using the VR simulation in chemistry education can increase student engagement in class, promote understanding of basic chem-ical principles, and augment laboratory experience. In this study, application way of the virtual reality technology in chemistry education is examined.

본 논문에서는 유·아동의 독서활동을 돕고자 기존에 있는 동화책과 가상현실 기술을 결합한 몰입형 동화 콘텐츠를 제안한다. VR 환경은 3D 입체 환경을 통한 중다감각적 상호작용을 가능하게 하여 학습자로부터 동기를 유발시킨다. 프로그램이 시작되면 컨트롤러가 활성화되며 동화보기, 미니게임 등 동화에 직접적으로 참여하여 즐길 수 있는 콘텐츠로, 향후 유·아동의 교육적인 면에서도 더욱 효과적일 것으로 기대된다.

HMD makes big issues about virtual reality in these days. Experience of virtual reality may cause different effects with experience of real world, so this is the reason why comparison studies are needed. There are many works about usefulness of virtual reality education but most of studies were considered as special training. This study was started for the long term memory effect of virtual reality education game. Difference study of memory between real world education game and virtual reality education game shows virtual reality system has smaller diminution of memory than real world. And environment existence was defined as a main effect of long term memory through the test.

This study is to examine the effects of gesture based interface and display methods to make an effective virtual learning environment. The gesture based interface can provide interactive interface to make objects in the virtual learning environment by generating natural movement of users' gesture. This natural functionality leads users to apply natural movements as they do in real actions. Because of the natural user interface, the gesture based interface is expected to maximize learning outcomes. This study examined how the gesture based interface can be used when a head mounted display is applied for a virtual reality learning environment. For this study 44 colleagues students were participated. Two display methods (head mounted display vs. monitor) and two interface (gesture based interface vs. joystick) were tested to identify which might be more effective. The study was applied to different learning tasks which require different levels of spatial perception. The dependent variables are three constructs of virtual presence (spatial perception, immersiveness, and realness) and task completion time and recall tests. This study discussed potential disadvantages of gesture based interface while it showed positive usages of gesture based interface.

Recently, research and development on immersive virtual reality(VR) technology to provide a realistic experience is being widely conducted. To provide realistic experience in immersive virtual reality for VR participants, virtual environments should consist of high-realistic environments using 3D reconstruction. In this paper, to acquire 3D information in real space using multiple cameras in the reconstruction process, we propose a novel method of optimal camera placement for accurate reconstruction to minimize distortion of 3D information. Through our approach in this paper, real 3D information can obtain with minimized errors during environment reconstruction, and it is possible to provide a more immersive experience with the created virtual environment.
