Gangwon-do is a representative leisure resort. However, the provision of tourism information has not escaped the existing image- and text-oriented simplicity. Therefore, a linkage strategy for the content business is needed to revitalize tourist attractions. In this paper, first, we provide a 360-degree rotating VR content authoring function. Second, we propose a dynamic platform including a function that allows users to easily author tour scheduling after registering VR content on a map. Finally, the proposal system provides pre-tourism customers with an opportunity to increase satisfaction by providing online pre-experience.

최근 ICT 산업게는 가상현실에 주목하고 있다. 시공간의 제약을 극복하고 실제 체험하는것과 비슷한 효과를 제공하는 VR 콘텐츠는 향후 유통 분야에도 폭넓은 활용이 예상된다. 대부분의 O2O 서비스에서 사용하고 있는 VR 기술은 단순히 360도 파노라마 형식의 사진을 보여주거나 VR 카메라로 중계 방송을 하는 콘텐츠가 대부분이었다. 따라서 본 논문에서는 3차원 VR 영상 스트리밍 서비스를 이용한 콘텐츠를 O2O 부동산 중개 서비스에 접목하여 360VR 컨텐츠 확장 가능성을 제시하고자 한다.

There exist a variety of VR(Virtual Reality) contents that have been developed by the use of the latest VR technologies. Unlike the rapid advances in the recent VR devices however, the development of VR based game contents that fully utilize such cutting-edge devices has been lackluster. Using more accessible form of smartphone-based HMDs(Head-Mounted Displays), we compare two popular VR presentation methods(a realistic 3D VR karaoke room and a 360 degree video karaoke room) and analyze their users' immersion and realistic perception. We expect that our study can be utilized as a supporting guideline for future smartphone-based VR content developments.

This paper is related to a new technology allowing a user to have a 360 degree viewpoint of the virtual wearing object, and to an object VR(Virtual Reality)-based 2D virtual textile wearing system using viewpoint vector estimation and textile texture mapping. The proposed system is characterized as capable of virtually wearing a new textile pattern selected by the user to the clothing shape section segmented from multiview 2D images of clothes model for object VR, and three-dimensionally viewing its virtual wearing appearance at a 360 degree viewpoint of the object. Regardless of color or intensity of model clothes, the proposed system is possible to virtually change the textile pattern with holding the illumination and shading properties of the selected clothing shape section, and also to quickly and easily simulate, compare, and select multiple textile pattern combinations for individual styles or entire outfits. The proposed system can provide higher practicality and easy-to-use interface, as it makes real-time processing possible in various digital environment, and creates comparatively natural and realistic virtual wearing styles, and also makes semi -automatic processing possible to reduce the manual works to a minimum. According to the proposed system, it can motivate the creative activity of the designers with simulation results on the effect of textile pattern design on the appearance of clothes without manufacturing physical clothes and, as it can help the purchasers for decision-making with them, promote B2B or B2C e-commerce.

야외에서 촬영 된 VR(Virtual Reality) 비디오는 의도하지 않은 흔들림을 동반한다. 흔들림을 포함한 VR 비디오는 사용자에게 시각적 피로감을 주고 몰입도를 저하시키기 때문에 VR 비디오의 흔들림을 제거하는 기술은 중요하다. 본 논문에서는 촬영 과정에서 흔들림이 발생한 VR 비디오 신호를 스티칭 단계 이전에 흔들림 보정하여 안정된 $360^{\circ}$ 비디오를 얻을 수 있는 알고리즘을 제안한다.

최근 영화, 스포츠 중계, 게임 등 다양한 종류의 콘텐츠가 VR 형태로 서비스되고 있는데, 이러한 360도 영상 서비스 환경에서 영상과 오디오를 더욱 실감나게 제공하는 기술에 대한 연구도 많이 이루어지고 있다. 오디오의 경우 스테레오, 5.1 채널 오디오 등과 같은 채널 기반 오디오가 방송, 영화 등에서 주로 사용되었는데, 최근에는 객체 기반 오디오, 장면 기반 오디오 기술의 적용이 시도되고 있다. VR 서비스에서도 더욱 실감 있는 오디오를 제공하기 위하여 이러한 최신 오디오 기술의 적용이 시도되고 있다. 본 고에서는 증강 현실 및 가상 현실에 활용될 수 있는 최신 오디오 기술에 대해 간략하게 살펴보고, 최신 오디오 기술이 어떻게 VR 서비스에 적용이 되고 있는지에 대해 살펴본다. 그리고, VR 서비스를 위한 규격 제정 측면에서 오디오 기술은 어떻게 진행이 되고 있는지에 대하여 간략하게 살펴본다.

VR (Virtual Reality) is one of the important research topics in the field of multimedia application system. The quality of the visual data composed from multiple pictures depends on the performance of stitching technique. The stitching module consists of feature extraction, mapping of those, warping, seam finding, and blending. In this paper, we proposed a preprocessing scheme to provide the efficient mask for seam finder. Incorporating of the proposed mask removes the distortion, such as ghost and blurring, in the stitched image. The simulation results show that the proposed algorithm outperforms other conventional techniques in the respect of the subjective quality and the computational complexity.

This paper presents a novel 360-degree video streaming system for large-scale immersive displays and its ongoing implementation. Recent VR systems aim to provide a service for a single viewer on HMD. However, the proposed 360-degree video streaming system enables multiple viewers to explore immersive contents on a large-scale immersive display. The proposed 360-degree video streaming system is being developed in 3 research phases, with the final goal of providing 6DoF. Currently, the phase 1: implementation of the 3DoF 360-degree video streaming system prototype is finished. The implemented prototype employs subpicture-based viewport-dependent streaming technique, and it achieved bit-rate saving of about 80% and decoding speed up of 543% compared to the conventional viewport-independent streaming technique. Additionally, this paper demonstrated the implemented prototype on UCSB AlloSphere, the large-scale instrument for immersive media art exhibition.

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.
