This paper studied tangible interaction design of VR platform and its applications that are economic In development process and cost, flexible by contents and installation conditions, and that has business potential for consumer market. The design solution uses video based virtual world and tangible interaction by motion tracking. Our platform enables a user to monitor their action and to collaborate with other users of remote place within attractive interaction feedback. We developed two design applications, Glass Xylophone 2003 and VR Class, in our platform. Glass Xylophone 2003 provides interactive music performance and helps self practice of glass xylophone. VR Class gives more serious distance learning experience with tutoring and group collaboration. They are presented in public exhibitions and tested by exhibition visitors. They showed application potential of this design solution in interactive game, distance learning, and entertainment field.

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.

Recently VR environment is used in many areas including mobile learning, smart factory. However HMD(head-mounted display) is required to a dedicated and expensive system with high-end specification. When designing a VR system, it is needed to handle performance, mobility and usability. Many VR applications need to handle diverse sensors and user inputs continuously in a streaming manner. In this paper we design a VR mobile platform and implement a low-cost mobile VR HMD running on the platform. The VR HMD supports 3D contents delivery in a mobile manner. It is used to detect the motion detection based on angle value of a VR player from accelerator and gyro sensor. The MPU-6050, 6-axis sensor, is used to get a sensory value and the sensory value is taken as an input to a VR rendering server on a Unity game engine that is generated 3D images.

The purpose of this study is to explore the narrative of VR disaster and safety Education introduced by disaster film narrative. VR(Virtual Reality) is be suitable technology for disaster and safety Education due to media characteristics as 'immersion', 'presence', 'interactivity', 'pleasure'. Disaster film narrative is able to be worth VR disaster and safety education as a variety of stories and educational effect. For this study, examine a theoretical study and a visiting research of 'Busan 119 Safety & Experience Center'. This study concludes that Firstly need to introduce catharsis effect, Secondly, build 'interactive narratives' that ensure active participation of users, Thirdly, introduce an 'adventure game' narrative element, Fourthly, introduce a hero-shaped narrative in which the user becomes a one-man hero, And lastly, need education as use user's multiple access and group experience learning. Therefore, This thesis is of academic value in that it suggest a desirable new direction of narrative in VR disaster and safety education.

Currently, virtual reality technology is actively applied in the entertainment and game fields, and development of professional programs is gradually increasing due to the rapid development of Internet and web technologies. As the current paradigm for healthcare changes from treatment to prevention, it is more important to take good care of it in advance so it doesn't get sick. This paper allows users to monitor the amount of exercise directly after using VR sports games. By using this system, users can exercise more interestingly and manage their own fitness by receiving an analyzed amount of exercise.

With the advancement of technology, there are almost no constraints on expression in virtual reality (VR) art; however, it still has some limitations. VR artists can be largely classified into two groups in terms of style. The first group is artists who create their works as a live performance. In this case, a major limitation is that the artist cannot see how the audience reacts to the work because he/she wears a VR device while performing, and the audience cannot fully experience the work, since they view it only on-screen without any VR devices. This problem can be solved if all members of the audience wear VR devices; however, that requires astronomical costs and brings about another problem related to device management. If the price of VR devices decreases as technology develops, it may help solve this problem. The second group is exhibition artists who regularly display their works online. In this case, the limitation is that their work using VR remains only in the virtual digital space. In this case, a solution may be creating space in exhibition halls, and providing VR devices to audience members in existing art exhibitions.

VR(Virtual Reality), which has drawn attention as a major area in ICT, is currently being used in various fields, including medical care, movies and architecture. Although VR technology is used in various fields, contents are mainly developed by creators where needs of users are easily left out of consideration leading to failure in forming a consensus between UI(User Interface) and UX(user experience). To identify the consumer preference and attribute level of VR game content, which is responsible for the largest proportion of VR contents, this study was designed to examine the consumers' preference properties of VR game contents through a Conjoint Analysis and derive the relative importance and weightings of each group. The study collected 166 questionnaires over a total of three months from May to July 2019, 150 of which were completed (90.4%). Statistic analysis was conducted using SPSS Ver. 25.0. The results of the study showed that the genre of the game (42.6%), number of players (24.0%), price for payment (20.3%) and game planning (13.1%) were important attributes in choosing VR games. The optimal mix of attributes was derived with new games, RPGs, multi-play and medium price (22,000 KRW). Before mentioning technology in the expectations of users who use VR game content, which is the most preferred among VR contents, this study recognized the need to have a fun and new experience through VR game content. Therefore, it is expected that this will serve as a reference for consumer behavior of VR game contents and research on VR game contents development.
