We have developed a method that enables a user to better understand and enjoy the contents of 3D digital archives, thereby enhancing the user's experience. The system's interactive interface, built using virtual reality technology, enables the user to "walk through" the archives, comparing two or the same content at different points in time. For example, a user can compare the proposed design for a building with the actual building and can compare the states of restoration of a cultural heritage site over time. This ability to perform multilateral comparisons enables the user to clarify the relationship between contents, the influence of one content on another, and the causal relationship between contents. Testing of a prototype system for a 3D digital archive of cultural heritage sites showed that it worked smoothly and that the users could easily operate the navigation system.

국민안전처는 2016년 국민의 생활안전 기반 강화를 위한 정책으로 맞춤형 소방안전교육과 소방안전 문화 확산을 위한 정책을 추진하고 소방안전 교육체제 마련을 위해 소방안전교육 방안을 계획 중이다. 이는 우리사회의 안전에 대한 문제점을 개선하기 위한 방안으로 본 연구가 선행되어진 이유이기도 하다. 현재 안전교육이 시행되고 있으나 실제현장과 같은 상황을 체험할 수 없으며 교육에 대한 이해와 만족도도 기초적인 수준이다. 이에 본 논문에서는 이러한 문제 해결을 위한 효과적인 대안으로 VR(Virtual Reality) 소방체험교육콘텐츠를 개발한다. 이는 화재진압과 대피훈련을 가상공간에서 체험하는 것을 목적으로 1)안전한 소방체험 환경제공 2)흥미를 유발할 수 있는 UI(user interface)제공 3)체험교육으로 소방교육현장에서 활용 4)예산 절감의 경제적 효과를 기대할 수 있다.

The growth of virtual reality(VR), which is regarded as a part of the 4th industrial revolution, is being delayed differently from the prediction. In this study, we briefly analyze these reasons from the point of view of CPND ecosystem. Virtual reality is a technology in which a user wears a device and accesses a platform through a network to use various contents. Therefore, balanced development of C-P-N-D ecosystem fields is important for successful popularization of virtual reality. In Korea, content, platforms, and devices, except for the network, are evaluated as having low competitiveness. While efforts to secure competitiveness in individual fields are important, it is also necessary to nurture network-based platforms that can utilize killer content. It should be kept in mind that simple breeding of killer content alone can not build an entire virtual reality C-P-N-D ecosystem, and the broadcast / media sector also needs to take this approach.

In order to realize foreign language education, various existing educational media have been provided, but there are disadvantages in that the cost of the parish and the media program is high and the real-time responsiveness is poor. In this paper, we propose an artificial intelligence English conversation system based on VR and speech recognition. We used Google CardBoard VR and Google Speech API to build the system and developed artificial intelligence algorithms for providing virtual reality environment and talking. In the proposed speech recognition server system, the sentences spoken by the user can be divided into word units and compared with the data words stored in the database to provide the highest probability. Users can communicate with and respond to people in virtual reality. The function provided by the conversation is independent of the contextual conversations and themes, and the conversations with the AI assistant are implemented in real time so that the user system can be checked in real time. It is expected to contribute to the expansion of virtual education contents service related to the Fourth Industrial Revolution through the system combining the virtual reality and the voice recognition function proposed in this paper.

In this study, the importance of each design element was analyzed by surveying experts in the development of Agro-Healing Virtual Reality Therapy System. It was found that the results of experts content importance were consistent with the results of consumer preferences in previous studies, such as psychological and emotional stability as the main effect the importance of sight and hearing, a relatively short time of 30 minutes or less, a low price of 5,000 won or less, technical factors that can satisfy the five senses, and various contents. When the spatial elements of the Agro-Healing Virtual Reality Therapy System were categorized into three major categories: elements and equipment, lines and paths, and sites and spaces, 'flowers', 'playgrounds', 'paths', 'sidewalks', 'rest areas' and 'gardens' were found to be highly important. Among the components of Agro-Healing Virtual Reality Therapy System, the usability was divided into eight major categories, including searchability, attractiveness, cognition, error handling, control, consistency, convenience, and feedback, and the importance was analyzed for each component. The significance of this study is that it suggests the design direction of virtual healing farm systems and provides effective information that can be used in the development of related systems in the future.

The aim on this thesis is to develop virtual construction designing experience web-site in order to help non-professional to predict the actual construction working result by self-construction design, provided by virtual reality program, sharing knowledge of architectural design and materials on internet to solve certain problems. The way of study is using case of virtual reality technology which is practically using in architecture era recently; in construction design, deducting realizable virtual reality technology of limitation and its solution; analyze case of construction designing program which is currently used by professionals; constitute required essential functions as UI(User Interface) when constructing. Followed by result of study, as a proposal, in service, technical, and UI sectors are the way to construct its objectives for internet based virtual construction experience web-site.

Virtual reality seems to be the center of the next generation platform, which is founded on various engines that can easily make device progress and content. However, the interaction between virtual reality contents and users is thought of as relatively requiring technological advances. In this paper, we propose a technique to improve the interaction technique based on the case of Virtual Figure Model Crafting (VFMC) to analyze the problem of interaction caused by virtual reality contents. We introduced the concept of Head-Up Display (HUD) to present a more natural interaction method. The HUD is the digital visual interface of the aircraft. The advantage of HUD visual interface is to minimizes the user's visual movement by displaying the information of the scattered view to the forward direction of the pilot. In other words, we can reduce unnecessary left and right movements that make it is possible to expect an effect of reducing fatigue and increasing immersion.

We implemented virtual reality training system for city gas virtual training platform using oculus $rift^{TM}$, gear $VR^{TM}$ and dome screen. And we carry out a survey targeting ordinary person using each device. The contents of survey are usability and reality about each training system and the goal of survey is a verification how to bring effectiveness using city gas governor safety training system. The survey method used each VR device for the ordinary person and investigated the difference. Based on the survey it was to find out the direction for the implementation of platform, could find out the possibility of a virtual training system.
