가상현실 기술은 다양한 유형으로 발전하고 있다. 해양경찰은 함정 조함 교육을 위해 두 가지 가상현실 환경에서 실습이 진행 중이다. 이 연구는 두 가지 가상 현실 환경에서 조함 교육효과가 어떻게 나타나는지 알기 위해 항해 위험성을 평가하고 분석하였다. 실물형은 데스크톱형보다 최근접거리가 더 길고, 대각도 타 사용 시간과 비상인지 시간이 더 길게 나타났다. 향후 해양경찰 함정 교육을 위한 최적의 가상현실 환경을 구축하고 확장하는데 기초자료로 활용할 예정이다.

Recently, with the rapid development of eXtended Reality(XR) technology, the development and use of education and training systems using XR technology is increasing significantly. In particular, in areas that involve great risks and high costs such as military training and counter-terrorism training, the use of XR based simulators is preferred because they can improve training performance, reduce training costs, and minimize the risk of safety issues that may occur in actual training, by creating a training environment similar to actual training. In this paper, we propose a plan to build and evaluate an XR based hyper-realistic counter-terrorism education, training, and evaluation system to improve the ROK police's ability to respond to terrorist situations using the 5G and AR based Integrated Command and Control Platform previously developed by the Korea Military Academy. The proposed system is designed to improve counter-terrorism capabilities with virtual training for individual and team units based on hyper-realistic content and training scenarios. Futhermore, it can also be used as a on-site command and control post in connection with a simulation training site and an actual operation site.

Objectives: Extended reality technology offers an innovative opportunity to enhance self-directed learning through interactive processes in healthcare education. This study aims to analyze research trends in the application of extended reality technology-based educational content in the field of healthcare. Methods: Through literature search, selection, and exclusion processes based on predefined criteria, we conducted an analysis of domestic healthcare studies employing extended reality technology, ultimately selecting and examining 39 relevant publications. Results: The analysis reveals diverse applications of extended reality across various fields such as medicine, dentistry, and nursing. Positive effects, including increased academic satisfaction, immersion, and interest, are observed, alongside challenges like media usage difficulties and cybersickness. Conclusions: Future research should focus on the development and application of extended reality-based educational content in diverse healthcare curricula, emphasizing both educational approaches and continuous technological advancements.

Recently, the importance of CPR training for the layperson has been emphasized to improve the survival rate of out-of-hospital cardiac arrest patients. An accurate and realistic training strategy is required for the CPR training effect for laypersons. In this study, we develop an extended reality (XR) based CPR training system and evaluate its usability. The XR based CPR training system consisted of three applications. First, a 3D heart anatomy image registered to the manikin is transmitted to the smart glasses to guide the chest compression point. The second application provides visual and auditory information about the CPR process through smart glasses. At the same time, the smartwatch sends a vibration notification to guide the compression rate. The 'Add-on-kit' is a device that detects the depth and speed of chest compression via sensors installed on the manikin and sends immediate feedback to the smartphone. One hundred laypersons who participated in this study agreed that the XR based CPR training system has realism and effectiveness. XR based registration technology will contribute to improving the efficiency of CPR training by enhancing realism, immersion, and self-directed learning.

The purpose of this study was to design a training program for pre-service elementary teachers, incorporating the concepts of extended reality technologies. This program contained the basic skills necessary for them to utilize in their future classrooms. To accomplish this, 12 undergraduate students of various majors enrolled in one of Korea's national universities of education were selected as research subjects. For a total of 6 times over 6 weeks, they participated in a training program learning the basic concepts of virtual, augmented, and mixed reality, as well as creating their own education software to use in simulated classes. To improve the quality of future research efforts, this study found it would be beneficial to: 1) expand the relevant support equipment, 2) provide students with preliminary, background knowledge of text-based programming, 3) introduce short-term, more intensive training, and 4) improve the survey methods for this research.

Despite the growing educational demand for the extended reality (XR) convergence content creation for non-IT students, fewer studies have attempted to education material development. In this paper, non-IT students' requirement to create XR convergence contents was analyzed and designed framework system specification. The object-oriented application framework (OOAF) was developed for non-IT students to create XR convergence contents through simple interaction methods such as drag and drop in-game engines. To evaluate the developed framework XR contents development course was operated with 26 industrial design majors sophomore in university. More than 90% of students succeeded in working on prototype XR contents in Oculus Rift. This result will be expected to improve the quality of XR contents creation education for non-IT students and contribute to the growth of the future convergence contents industry.

This study explores the usability of extended reality (XR) content tailored for production process training, with a focus on user experience. Participants engaged with extended reality training modules, and qualitative data was subsequently collected through interviews. These interviews evaluated the hardware, user interface, and overall user satisfaction. The analysis utilized python packages for keyword extraction and word cloud visualization, offering insights into user perceptions. The findings revealed that although the hardware was deemed comfortable, concerns were raised regarding its weight and heat emission. The interactive interface, which relies on hand tracking, encountered issues with recognition rates, leading to suggestions for alternative input methods. Users acknowledged extended reality's potential impact on industries like healthcare and education, sharing both positive and negative views on the technology. This research enhances our understanding of user responses and guides the future enhancement of extended reality content for industrial applications, aiming to improve its quality and practical usability

2003년 미국 IT기업인 린덴랩에서 개발한 3D 가상현실 사이트인 세컨드라이프가 최근 인터넷 서비스 시장에서 큰 주목을 받고 있다. 그 까닭으로는 세컨드라이프가 3D 기반 인터넷 기술과 사용자의 서비스 경향을 충실히 담고 있다는 점과 현실과 밀접히 연결되는 부분을 많이 가지고 있어 현실 세계에 미치는 영향력이 점점 증가세에 있다는 것을 들 수 있다. 최근의 우리나라 교육 현장에서는 다양한 ICT활용 교육을 통하여 학교에서 이루어지는 교과 지도와 생활 지도를 온라인으로 확장하고 있으며, 또한 기술의 발달에 힘입어 모바일 교육과 U-Learning과 같은 새로운 교육 방법과 함께 온라인에서 주목받는 우수한 소프트웨어를 학교현장에 도입하려는 노력을 시도하고 있다. 본 연구에서는 Second Life가 머지않아 교실수업과 인터넷수업을 잇는 매개체로 사용될 것이라 보고 세컨드라이프의 국내외 적용사례를 살펴보고 초등교육에서 활용하기 다양한 방안을 제시하고 장단점을 분석한다.
