대기질 악화로 인해 실내운동에 대한 중요성이 증가하고 있다. 하지만 실내에서 사용가능한 가상체험 장비는 비싼 가격으로 일반 가정에서 쉽게 접할 수 없는 현실이다. 본 연구에서는 저비용으로 활용가능한 로잉머신과 개인 스마트폰을 이용한 실내 운동 솔루션을 제안한다.

가상현실은 시·공간을 초월하는 경험이 가능하며 아이들의 몰입감과 학습효과를 높일 수 있어 교육 도구로서의 가치를 인정받고 있다. 정부는 VR 기기를 전국의 초등학교에 보급하고 있지만, 양질의 교육용 실감형 콘텐츠는 부족한 상황이다. 따라서, 본 논문에서는 가상현실 기술을 활용한 국악기 연주 체험 프로그램을 제안하였다. Unity의 물리 엔진과 Oculus의 햅틱 기능을 이용하여 전통 국악기 중 편경을 실감 나게 연주할 수 있도록 가상환경을 구현하였다. 리듬 게임 형식을 적용하여 아이들의 흥미 또한 유발하였다. 이 프로그램을 통해 국악기를 직접 연주하며 해당 국악기에 대한 지식을 자연스럽게 습득할 수 있을 것이라 기대한다.

본 논문에서는 가상 악기 시스템의 제작에 대하여 기술한다. 가상 악기 시스템은 (이하 VMS라 칭한다.) 가상의 악기를 연주하는 것을 컴퓨터를 이용하여 체험해 볼 수 있게 한다. 또한 멀티 터치가 가능한 지능형 인터페이스 플랫폼인 Touch-Face를 기반으로 동시의 여러 사용자가 악기를 연주 할 수 있도록 한다. Touch-Face에서의 터치를 인식하여 맨손의 손동작에 의해 상호작용을 구현한다. 이 시스템은 특히 별도의 디바이스나 콘솔을 필요로 하지 않고 시스템 내에 가이드창이 있어 사용자로 하여금 쉽게 따라 할 수 있게 하고, 어린이들을 대상으로 하여 실감나는 연주 체험을 할 수 있으며, 악기를 다루는데 보다 경제적이고 효율적으로 학습하는데 활용될 수 있다.

가상현실 기술을 활용한 역사 교육 콘텐츠 개발은 미래 교육 환경에 적응하고 학습 경험을 혁신하기 위한 중요한 도전이다. 이를 통해 시각적·체험적 학습을 강화하여 학생들의 흥미와 참여도를 높일 수 있으며, 다양한 교육 자료를 가상 현실에서 체험하면서 깊은 이해를 도모할 수 있다. 메타버스 기술은 역사적 사건들을 현실과 가상의 경계를 넘어 재현할 수 있는 독특한 기회를 제공하며, 이를 통해 학생들은 적극적으로 학습에 참여하며 창의성과 문제 해결 능력을 키울 수 있다. 따라서 이 콘텐츠의 개발은 교육의 미래를 모색하고, 새로운 학습 환경에서의 효과적인 교육 방법을 개발하는 데에 중요한 역할을 할 것으로 기대된다.

The Ministry of Public Safety and Security plans to expand fire safety education infrastructure to provide customized fire safety education, spread fire safety culture and develop a tailored fire safety education system as a part of the 2016 Citizens' Safety Improvement Policy. This study has also been designed to improve safety problems in the Republic of Korea. Even though safety education has been given, citizens aren't still able to experience a close-to-real situation. In addition, their understanding and satisfaction with the curriculum are very low. Therefore, this study offers VR fire-extinguishing experience education contents as an effective alternative. With a goal of having the participants experience fire extinguishing and evacuation drill in a virtual space, this program has the following advantages: i) safe fire-extinguishing experience; ii) UI to create fun ; iii) useful in fire-extinguishing education; iv) budget saving. we configure the VR fire experience system structure and hardware by applying UX design methodology. We also develop for VR-specific motion recognition plug-in and controller that can be feeling in HMD environment.

Social study for province textbook is very difficulty for experience and learning in classroom because the contents of social study for province text book is consist of contents about very far away places. And there are less contents than normal subject. Especially, children need experiences and enough contents for learning in social study for province textbook. The purpose of this paper are as follows: 1) design and implementation of PVR contents 2) applying 4th grade social study for province textbook 3) inspecting for satisfaction degree and result of students about the efficiency of PVR contents.

The purpose of this study is to derive the characteristics of interaction design for each stage of content composition so that it can be referred to in the planning and production of virtual reality safety education contents. It was confirmed that each of the following interaction design features was found in the three configuration steps: acquisition of situation response procedure knowledge, accident situation experiential learning, and content confirmation and evaluation. First, it was revealed that the quality of experience was controlled by increasing the fidelity of behaviors and reducing general and repetitive behaviors in order to emphasize the educational content-related experiences in the learner experience stage. Second, in order for learners to easily recognize main interaction objects in order to acquire information on safe behavior procedures in unfamiliar environments, use of spatial UI or signifiers using arrows or symbols, posts that specifically instruct actions, and multisensory signals Therefore, it was found to be important to emphasize essential actions in a way that lowers the degree of freedom of user experience, and the proportion of non-realistic interactions for cognitive interactions was found to increase. Lastly, in the confirmation and evaluation stage of the experience, it is important to use the meta UI to alleviate negative experiences such as physical damage after experiencing a safety accident situation,

Projector-based visual systems are widely used for VR and experience display applications. But the illumination irregularity on the screen surface due to the screen material and its light reflection properties sometimes deteriorates the user experience. This phenomenon is particularly troublesome when the participants of the head tracking VR system such as CAVE or the motion generation experience system continually move around the system. One of reason to illumination irregularity is projector-screen specular reflection component to participant's eye's position and it's analysis needs high computation complexity. Similar to calculate specular lighting term using GPU's programmable shader, Our research adjusts every pixel's brightness in runtime with given 3D screen space model to reduce illumination irregularity. For doing that, Angle-based brightness compensate function are considered for specific screen installation and modified it for GPU-friendly compute and access. Two aspects are implemented, One is function access transformation from angular form to product and the other is piecewise linear interpolate approximation.

In this study, we designed and developed the virtual reality Exergame using the smart mat and the camera sensor for exercises in indoor environments. For detecting the gestures of a upper body of users, the KINECT camera based the gesture recognition algorithm used angles between user's joint information system was adopted, and the smart mat system including a LED equipment and Bluetooth communication module was developed for user's stepping data during the exercises that requires the gestures and stepping of users. Finally, the integrated virtual reality Exergame system was implement along with the Unity 3D engine and different kinds of user' virtual avatar characters with entertainment game contents such as displaying gesture guideline and a scoring function. Therefore, the designed system will useful for elders who need to improve cognitive ability and sense of balance or general users want to improve exercise ability and the indoor circumstances such home or wellness centers.

The purpose of the study was to provide an educational environment for designing and producing virtual reality practice contents that can be used in semiconductor production lines and clean rooms. Through this process, the user can acquire practical knowledge through experiences close to reality, such as experiencing the main semiconductor solar cell manufacturing facilities as well as procedural knowledge before and after entering the clean room.. In particular, it provides users with an immersion experience close to reality by creating an environment for experiential content necessary for semiconductor and solar cell manufacturing processes and clean room entrance procedure experiential content, which is expected to improve education immersion, realism, cost, efficiency, and education satisfaction. Depending on the characteristics of Dangerous, Impossible, Counter-productive etc, immersive content makes learners immersed in the learning content, induces proactive/active learning, and embodies the learning content, resulting in positive results in the field of improving educational effectiveness.
