  • In the construction, VR(Virtual Reality) is simply used by users to implement and experience 3D modeling in virtual reality, such as safety, practical education, and promotion. The VR related research includes content development and visualization simulation such as disaster safety evacuation simulation and design education contents. Research on developing suitable VR and presenting directionality is insufficient, which is required in practice. Therefore, in this study, prior to the development of VR suitable for the construction, quantitative evaluation, and analysis based on the judgment of experts are performed. However, the research was conducted on the design stages, which are believed to have high needs and application effects of VR during the lifecycle of construction. There are nine tasks that can be applied to VR in the design stage, and these tasks were evaluated and analyzed using IPA(Importance Performance Analysis) by surveying the level of expectations, importance, and performance. As a result, it was evaluated and analyzed that VR and content development was necessary for the review of member interference and collaboration work for decision making among related stakeholders. The results of this study are expected to be used as basic data for the development of VR to be applied in the design stage to the future.

  • This study has derived the patents of the technology that have been filed and registered so far to investigate the trends of virtual reality(VR) experience contents technology, and analyzed them focusing on core patent technologies. The patents of Korea, USA, Japan, Europe and PCT, which were released until June 2020, were targeted, and patent search was conducted using WISDOMAIN search DB. The keywords for patent search were related to experience technology using VR, and a total of 1,013 data were obtained after creating a search formula by combining the derived keywords. Among them, a total of 65 data were extracted from the result of selecting valid patents, and a political analysis was conducted on them. Looking at the overall application trend, most of Korean patent applications accounted for, and noise patents are system-related devices to implement VR technology. The United States and Europe are focused on developing augmented reality(AR) technology, the study found. The technology of VR experience has increased rapidly since 2017, and the technology growth stage is the period from the beginning to the growth stage. As a result of examining the valid patents related to VR experience, technology was searched in various fields such as rural tour, exhibition, education, and performance, and patents for contents writing and general virtual experience related technology were also searched. If we predict the possibility of development of VR industry in the future, it is necessary to respond to preemption of intellectual property rights by proceeding technology development and patent application for more diverse fields.

  • Augmented Reality, virtual reality in recently attracted attention throughout the world. and Mix them mixed reality etc., it has had a significant impact on the overall pop culture beyond the scope of science and technology. The world's leading IT company : Google, Apple, Samsung, Microsoft, Sony, LG is focusing on development of AR, VR technology for the public. The many large and small companies developed VR hardware, VR software, VR content. It does not look that makes a human a human operation in the cognitive experience of certain places or situations or invisible through Specific platforms or program is Encompass a common technique that a realization of the virtual space. In particular, out of the three-dimensional image reveals the limitations of the conventional two-dimensional structure - 180, 360 degree images provided by the subjective and objective symptoms such as vision and sense of time and got participants to select it. VR technology that can significantly induce the commitment and participation is Industry as well as to the general public which leads to the attention of colostrum. It was introduced more than 10 related VR works Year 2015 Sundance Film Festival New Frontier program. The appearance VR content : medical, architecture, shopping, movies, animations. Also, 360 individuals can be produced by the camera / video sharing VR is becoming an interactive tunnel between two possible users. Nevertheless, This confusion of values, moral degeneration and the realization of a virtual space that has been pointed out that the inherent. 4K or HUD, location tracking, motion sensors, processing power, and superior 3D graphics, touch, smell, 4D technology, 3D audio technology - It developed more than ever and possible approaches to reality. Thereafter, This is because the moral degeneration, identity, generational conflict, and escapism concerns. Animation is also seeking costs in this category Reality. Despite the similarities rather it has that image, and may be the reason that the animation is pushed back to the VR content creation. However, it is focused on the game and VR technology and the platform that is entertaining, but also seek new points within the animation staying in the flat Given that eventually consist of visual images is clear that VR sought. Finally, What is the reality created in the virtual space using VR technology could be applied to the animation? So it can be seen that the common interest is research on what methods and means applied.

  • Advances in IT technologies are developing VR content technologies that provide five senses information to users and interact with them. These VR content technologies are widely used by users not only for time and space limitations but also for providing immersion experiences. VR contents are contents that allow users to experience images that are played on the screen through five senses such as augmented reality, virtual reality, and holograms as well as visuals. VR games are also becoming more diverse in interfaces for the interaction of users with VR games. This study recognized the importance of the interface and analyzed the impact of the application characteristics of VR game UI on user experience and satisfaction from the user perspective. Research shows that VR game UI interacts with user experience and satisfaction. This appears to affect user experience based on how well people using VR game UI can understand and utilize the characteristics and functions of UI.

  • VR image content producers are now terrestrial broadcasters, movie studios, game companies, and VR content producers (productions). As the VR market begins to form, investment in VR image content production is also expanding. The terrestrial KBS 'Summter VR' has been produced steadily from 2016 to 2017. 2D and VR images were simultaneously broadcast. If we compare and analyze these two image data, we could get a meaningful presentation. In this paper, 'Summter VR' is analyzed by cutting the image by time. "Summter VR" was using a long take for an average of 30 seconds or more, and at the same time, it was choosing a beautiful place so as not to fall into the boredom of long take directing. Most of the images of 'SummterVR' were long take techniques using the mise en scene VR technique.

  • 360 VR 콘텐츠는 기존의 선형적인 일반 영상에 비해 사용자에게 더 많은 정보와 높은 몰입감을 제공할 수 있어 의학, 군사, 교육, 게임 등 다양한 분야에서 활용되고 있다. 최근에는 모바일 기기의 성능 향상과 통신기술의 발달에 힘입어 모바일 네트워크를 사용한 360 VR 콘텐츠 소비가 증가하는 추세이다. 모바일 네트워크는 대역폭이 한정적이고 가변적인 특성이 있어 이를 통해 용량이 큰 360 VR 콘텐츠 전송 시 초기 접속 지연 및 재생 끊김이 발생하여 사용자의 만족도를 감소시킬 수 있다. 이에 본 논문은 위에 언급한 문제를 해결하기 위해 360 VR 콘텐츠 전송 시 전체 요구대역폭을 감소시키고 사용자 초기 접속 속도를 향상시키는 것을 목표로, 360 VR 콘텐츠의 지오메트리 값과 사용자의 요(i.e. yaw)값을 활용하여 각도 기반으로 사용자의 현재 시점에 해당하는 타일을 확인하고 해당 타일에 높은 비트율을 할당하는 방법 및 웹 기반 전송에 대해 연구 개발하였다. 이를 위하여 웹 기반 3D 렌더링 API 인 WebVR API, HTTP Adaptive Streaming 기술의 표준 MPEG-DASH의 dash.js API를 활용하여 개발하고, 성능 확인 실험을 통해 요구대역폭 감소, 클라이언트 접속 속도 향상을 제시한다.
