본 논문은 제조 산업 현장에서의 업무 능력 향상을 위한 XR 교육훈련 콘텐츠의 가변적 시나리오를 제안한다. 가변적 시나리오를 적용한 XR 교육훈련 콘텐츠는 교육훈련 관리자가 자유롭게 시나리오를 가감할 수 있어 동일한 콘텐츠 내에서 다양한 시나리오로 콘텐츠를 구성할 수 있는 특징을 가진다. 이는 기존 하나의 시나리오로 반복되는 교육훈련의 한계를 해결할 수 있으며, 현장에서 발생할 수 있는 돌발적 상황 및 변화되는 업무 프로세스를 효과적으로 진행할 수 있을 것이다.

One of the most negative social changes of the last decade is population aging which leads to 19 times more patients with Mild Cognitive Disorder(MCI). It is well established that MCI is the most important state that can prevent dementia with early diagnosis and intervention. However, the social security system for patients with dementia is not working properly due to the coronavirus pandemic and the limited human power. This article proposes design principles for dementia training programs of extended reality devices. and The findings in this study provide a guide for considering the cognitive and physical and social functions of patients.

XR(가상 및 확장현실)에서의 리얼타임 그래픽은 조명이 제 역할을 하지 못하면 인물이 공간감이 느껴지지 않거나 스킨톤이 맞지 않아 이질감을 초래한다. 본 논문에서는 Art-Net 시스템을 활용하여 실제 조명과 가상조명에서의 배경 및 인물의 컬러를 동기화하는 방법을 제안하였다. 제안된 Art-Net 시스템을 통해 인물의 공간감을 향상 시킬 수 있을 뿐만 아니라 보는 이의 몰입감을 높였다.

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.

Extended reality-assisted training offers repeatable learning opportunities at a low cost. This paper proposes a smart glass application for training core nursing skills to nursing students, who often need to memorize and practice training sequences. The proposed smart glass application interactively presents a series of instructions to help students remember and perform two core nursing skills in the correct order. We conducted a usability test on 30 undergraduate nursing students in their third year using the smart glass application. Our initial findings show that many students have positively evaluated the possibility of using smart glasses for training, but have also encountered several challenges with the smart glass application's user interface, which takes time to adapt.

최근에 국내외 실감형 콘텐츠 산업의 가파른 성장에 따른 실감콘텐츠산업에 대한 관심이 높아지고 있은 상황에서 VR, AR, XR 시장은 혁신적인 변화를 주도하고 있다. 실감형 기잔의 기기의 게임들은 기존의 게임과는 다른 방식의 품질보증(QA) 접근 방식을 요구한다. 전통적인 2D 게임과 달리 물리적 상호작용과 환경 인식 기능같은 부분이 다르기 때문이다. 본 논문에서는 가상현실, 증강현실, 확장현실 기반의 게임에 대해서 테스트 시 각 기기마다 고려해야 할 사항들에 대한 내용들을 제시하고 해당 사항들에 대해서 효과적인 방안을 제시해본다.

This paper has suggested the necessity of introducing training contents using XR(Extended reality) technology as a way to lower the high rate of nursing accidents among unskilled technical personnel in domestic shipbuilding industry, focusing on cable pulling using winch. The occurrence rate of nursing accidents in the domestic shipbuilding industry was almost double(197.4%) (2017~2020) when compared with other manufacturing industries. In particular, it is worth noting that more than 31.8% of nursing accidents in the shipbuilding industry occurred among workers whose job experience is no more than 6 months. Most of new workers are seen to have hard time due to several factors such as lack of work information, inexperience, and unfamiliarity with the working environments. This indicates that it is essential to incorporate more effective training method that could help new workers become familiar with technical skills as well as working environments in a short period of time. Currently, education/training at the domestic shipyard is biased toward technical skills such as welding, painting, machine installation, and electrical installation. Contrary, even more important training required to get new workers used to the working environment has remained at a superficial level such as explaining ship building processes using 2D drawings. This may be the reason why it is inevitable to repeat similar training at OJT (On-the-Job Training) even at the leading domestic companies. Domestic shipbuilding industries have been attracting a lot of new workers thanks to recent economic recovery, which is very likely to increase the occurrence of disasters. In this paper, the introduction of training using XR technology was proposed, and as a specific example, the process of pulling cables using winches on ships was implemented as XR-based training content by using Unity. Using the developed content, it demonstrated that new workers can experience the actual work process in advance through simulation in a virtual space, thereby becoming more effective training content that can help new workers become familiar with the work environment.

Prior research on Extended Reality (XR) has been a starting point for the development of the Metaverse. It is also a concern for researchers in the tourism field since it can enhance the tourist experience. Metaverse Tourism provides a virtual experience of the tourism destination for the users. It is potentially developed and predicted to be the future of tourism, enhancing the tourist experience through communication between humans and avatars and providing a new option for tourists to enjoy leisure activities. Recently, discussion on Metaverse tourism is still emerging, with some open talks from researchers in the intersections between information technology and tourism. This study extends prior studies by proposing six Metaverse tourism elements and categorizing them into core and supporting elements. Then, we analyze the consequences of those elements on the Tourism Experience Journey to enhance each stage with different characteristics. This study can contribute to continuing recent dialogues among scholars on how Metaverse can be applied in the tourism sector by proposing six elements that should be considered in developing and creating Metaverse services.

The purpose of this study is to propose a plan to establish a system that can maximize the effectiveness of disaster safety training. A review of previous studies and analysis of current status cases was conducted to examine the current level of data, systems, demand technologies, laws, and systems for related fields. A disaster safety training system linking digital twin and extended reality technology was proposed, and a study on the construction plan was conducted for this. It is hoped that the results of this study can contribute to the advancement of the disaster safety training system and reduce disaster damage.
