After the declaration of the Covid-19 pandemic impacted most of the industries resulting economic fallout. Firms sought for solutions of governments regulations to prevent spread of infectious diseases. This led to demand rise of digital layer and spectrums of virtual reality. Replacing the reality in to virtual and interactions with the digital contents by augmented reality, the consequences were decrement of human-to-human contact. Concerns of Covid-19 and public interests of digital solutions has led to significant amounts of research and developments of Virtual/Augment Reality resulted to driven up new terms of extended reality. However, the uses in industries and the characteristics of the extended reality are currently not defined. In this paper the goal is to define and classify the uses and characteristics of extended reality based on previous researches suggested by research institute. By developing a new classification models of extended realities core technology, uses of industries and utility to analyze trends of extended reality. Two separate classification models of uses of industries and utility will be used as a tool by creating a linkage matrix. The x-axis is divided by utiliy classification model of extended reality. The y-axis are divided into classification model of uses in industries. This matrix will be used as a tool to present a guideline for industry-utility development where extended reality can be served as a service

최근 코로나 19의 확산으로 인하여 코로나 감염으로 인한 외부 방송 촬영에 제약이 생기면서, 제작환경은 실외에서 실내의 가상 환경 제작 수요가 크게 증가하고 있다. 이에 확장현실 제작 기술이 방송 제작에 적극 활용되고 있다. 확장현실은 외부의 제작 환경을 몰입형 LED월 시스템 기반으로 가상의 그래픽으로 내부 스튜디오 제작환경에서 제작 할 수 있어 방송에서는 확장현실 관련 시스템 및 그래픽 콘텐츠, 운영기술 개발이 요구되고 있다. 이에 본 논문은 확장현실 콘텐츠를 제작 할 수 있는 '몰입형 혼합현실 시스템'을 제안한다. 특히, 확장현실 환경에서 원격으로 AR과 VR 콘텐츠의 동기를 맞추어 운영할 수 있도록 개발된 '원격제어 타임라인 디렉터'를 통해 AR/VR 콘텐츠를 재생 및 입출력을 제어할 수 있다. 본 시스템을 통하여 그래픽 기반의 AR/VR 시험 그래픽 콘텐츠 및 실사 기반의 360 콘텐츠 기반 확장현실 시험 콘텐츠를 개발하였으며, 상용카메라 추적시스템과 연개하어 자연스러운 추적 및 합성 그리고 타임라인 디렉터의 사용자 인터페이스를 이용하여 확장현실 콘텐츠를 제작 및 운영 할 수 있음을 확인하였다.

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.

Extended Reality (XR), such as virtual and augmented reality, has huge potential for immersive data visualization and analysis. In XR, users can interact with data and other users realistically by navigating the shared virtual space, allowing for more intuitive data analysis. However, creating a visualization in XR also poses a challenge because complicated, low-level programming is required, which hinders broad adaptation in visual analytics. This paper proposes an interactive visualization authoring tool based on hand gesture for immersive data visualization-Gadget Arms. The proposed system provides a novel user interaction to create and place visualization in the 3D virtual world. This simple, but intuitive, user interaction enables user designs the entire visualization space in the XR without using a host computer and low-level programming. Our user study also confirmed that the proposed user interaction significantly improves the usability of the visualization authoring tool.

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.

In an era where non-face-to-face meetings become common, eXtended Reality(XR) is rapidly developing and filling areas that are not satisfied in online meetings based on existing photos/video method. In particular, general users are also able to easily access and use HMD-type mixed reality devices. However, the basic operations applied in HMD-type in Mixed Reality(MR) with hands as the main input tool do not have a standardized system, and each manufacturer operates in a separate response to each other's hand movements. Therefore, this study considered that a systematic hand motion matching system considering the usability and efficiency of operations performed in mixed reality was necessary, and conducted a study to clarify this. First, the basic operation performed in the MR environment and its attributes were investigated, and at the same time, the structure of the hand and the attributes of the possible hand movements were identified. Based on the identified properties, it is intended to present a system that can intuitively and efficiently match basic operation properties in the MR environment with subtle operation properties according to the structure/context of the hand.

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.
