With the development of virtual reality (VR)-related technology and the advent of the 5G era, VR-based streaming games or content have been developed and transmitted at high speed. Although VR technology is also being applied in education, health care, manufacturing, and production fields, its main application is for entertainment. VR technology has been developed based on hardware and various contents have been developed accordingly; however, the number of VR content with high entertainment value is insufficient, and there are primarily hands-on contents. In this paper, we propose a method for developing an writing tool that can enhance the productivity in the development and editing of VR content and create VR contents based on a timeline by reflecting the storytelling rather than by a simple empirical type to solve the bias in content style. The proposed VR content writing tool is expected to increase the productivity in VR content development and contribute to the creation of various styles of content. Its implementation can enable developers to create specific stories in a timeline and support several animation effects.

Recently, in the Game industries, they are increasing to use of game engines to reduce the development cost of 3D content and software. In particular, Unreal Engine provides a blueprint visual scripting function that enables software production without programming (coding). Although High-end video content can be produced, the problem is that content development is complicated and requires advanced manpower. To solve this problem, we propose an optimized VR game context process. This is because 1) a Blueprint visual script is used, 2) VR games with various interactions can be produced, 3) Non-majors in the software field (or groups) can develop advanced content. In various related industries such as defense, medical care, manufacturing, and construction, we may easily develop any game content without programming with our refined VR rhythm action game development process. We expect to reduce the development cost with the process advantages in the game industries.

Various 3D contents are being developed using Unity 3D game engine. In this paper, the 3D content of horseback riding game, the first VR game in the country, is designed and developed. The existing riding simulator is investigated and compared to the VR riding game developed. We consider various games developed using Unity 3D game engine and serve previously developed tangible games. It is expected that development of VR riding games will prepare a new chapter in VR experience-type games. We propose the content development environment and scenario of VR riding game and present the main algorithms and main modules for real-time synchronization. The developed riding game contents are deployed to the riding system and are operated for commercial use in conjunction with the riding device. Through monitoring VR riding system, problems are derived and improvement measures are proposed. We offer a variety of additional development options to make the game more realistic in the future.

Currently, hardware companies such as Oculus, Samsung, and HTC are producing virtual reality devices, and game software development companies are developing or servicing VR games using these devices. Accordingly, the VR game market is expected to continue to grow in the future. However, in order for the VR game market to become active, various problems raised during game development and service must be resolved. This paper investigates solutions to problems raised during the development and service of VR games, such as cyber sickness, risk of injury due to environmental restrictions during play, and reconnection induction problems. Cybersickness can be alleviated by utilizing multiple GPUs for each display processing to achieve higher frame rates and optimizing play space design. Environmental constraints during play can be mitigated by optimizing space design, and the problem of inducing reconnection can be solved by continuously providing the motivation and purpose used in existing game methods. Through this, we were able to apply it to develop VR content that can be played continuously.

Virtual reality is being increasingly used for healing and therapy for mental health. In this study, we developed VR-based immersive content that enables virtual travel without the limitations of time and physical conditions. We aim to develop and produce VR content for relaxation and meditation using the beautiful natural scenery. To make realistic and immersive content, we took a video of natural sceneries with a small UAV connected to a VR camera. The content was developed through stitching, video editing and post-processing of the initially captured video data, and then the created VR video was inserted into the VR device. The produced content will be helpful for stress and used to heal the mind and body of exhausted modern people by providing the place with great scenery and sound in an immersive way at any time.

이 연구는 원예 기반 VR 콘텐츠를 개발하여 사용자들이 혼란스러운 일상에서 쉼을 찾을 수 있도록 하는 것을 목표로 한다. 텔레포트, 식물도감, 인벤토리, NPC 기능, 그림 그리기 게임 등을 활용하여 사용자의 참여도와 몰입감을 높이고, 감정적 안정감을 제공하며, 창의성과 집중력을 향상시키는 힐링 콘텐츠를 구현하였다. VR 기술을 이용한 정원 관람 콘텐츠는 현실과의 차이를 극복하기 위한 기술적인 연구와 개발이 필요하며, 이를 통해 콘텐츠의 현실성과 체험의 완성도를 높일 수 있다. 높은 해상도의 디스플레이, 고성능의 프로세서, 센서 등을 사용하여 VR 체험의 현실성을 증대시키고, 사용자 피드백을 수집하여 지속적으로 개선할 예정이다. 이를 통해 사용자들이 스트레스를 해소하고 감정적인 안정감을 느끼며, 현실에서 불가능한 경험을 제공함으로써 새로운 방법을 제시한다.

Immersion is a features of VR technology, and the most important condition for evaluating VR experience. With the improvement of VR technology, including the presentation accuracy of VR content, the degree of interaction is diversified, the user's immersion in VR equipment should not only be improved technically, but researched from the user's perception level. The paper defines two important factors, immersion and presence, in a participant's experience with a VR device. Although the current technology can already simulate the real environment information visually and audibly, the content of the VR environment is not enough for us to achieve a completely real experience. Based on the Flow theory of Csikszentmihalyi and the sensory immersion achieved by current technology, this paper proposes the key factors of how to achieve conscious immersion for users in VR media. We prove that immersion is an indicator of the true degree of sensory simulation of VR equipment and is the basis for the realization of flow experience. What really makes the participant feel a perfect experience is the content provided by the VR environment and gave participants a sense of presence, it is not limited to video or games. On the premise of the Multi-Sensory, Immersion, Interactivity and Imagination experience achieved by using virtual reality technology, combined with the content creation of flow theory, the interactive immersion achieved by users is an important method to realize the awareness immersion of VR equipment.

본 연구의 목적은 새로 등장한 4차 산업혁명과 융합신산업의 핵심인 VR 콘텐츠 산업의 문제점과 이를 해결하기 위한 대안을 모색하고자 한다. 전문가 심층면담을 통해 VR 콘텐츠 산업 발전을 가로막는 요소를 수집하였다. 그 결과 VR 시뮬레이터의 콘텐츠 변경 시 심의 간소화, 게임산업법 내에 'VR 시뮬레이터' 규제 법령을 신설, 투입금액 다양화 등이었다. 심의 간소화는 신규 플랫폼 사업을 위한 기초를 제공한다. 신규법령 신설은 VR 콘텐츠의 특성을 적절히 반영하고 기존 법규에 의한 불필요한 규제를 피하기 위해서이다. 다양한 투입방식의 도입은 신규산업에 대한 적극적인 시장 확대를 위한 것이다. 본 연구는 기존 법제도가 신규산업의 발전에 방해를 주는 요소를 살펴보고 그에 대한 대안을 제시함으로 써 신규 산업을 안전한 생태계에서 발전할 토양을 마련하는데 큰 도움을 줄 것으로 기대된다.

인간의 외부 인지 감각을 인공적인 기술로 자극하여 실제와 유사한 체험을 제공하는 가상현실(VR, Virtual Reality) 기술은 실 환경에서 제한되는 훈련 환경을 제공하는 대안으로 산업 분야 안전사고 예방 또는 조치에 대한 훈련시스템 구현 핵심 기술로 응용이 시도되고 있다. 하지만 3D 모델링과 소프트웨어 코딩으로 구현되는 시각체험 VR 환경 즉, 훈련용 콘텐츠는 개발에 많은 자원이 요구되어 훈련시스템 구축에 어려움을 주고 있다. 본 연구에서는 VR 기반 훈련용 콘텐츠 구현에 있어 동적 가시화 컴포넌트(VRDC, VR based Dynamic visualization Component)를 활용하는 방안을 제시하며 플랜트 안전훈련 시스템에 이를 적용함으로써 실용성을 검증하였다.

Practice through virtual reality can increase the educational effect regardless of time and place, and it is an educational method that is being pursued even in the situation of COVID-19. On the other hand, for VR-based education, related technology development and content development must be made, and experiential methods (flipped learning, blended learning, hybrid learning) must be provided in the educational process. The development scenario was developed with the contents of drone qualification test (ultra-light unmanned multicopter) and drone practice and the possibility of non-face-to-face self-directed learning (flipped learning, blended learning, hybrid learning). It is expected that the quality of vocational education related to drones and the effect of high education will be improved through the contents, and it is thought that it will be possible to suggest a direction for the development of various vocational education contents in non-face-to-face education.
