  • 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.

  • 최근 3D 그래픽스 기술과 관련된 기기들의 비약적 발전을 통해 가상, 증강, 확장 현실이라는 기존의 현실 세계에 새로운 정보를 더하는 연구가 활발하게 진행되고 있다. 우선 앱 기반의 가상, 증강, 확장 현실을 구현하는 과정에서 기기별 또는 브라 우저별, OS별로 개발 환경이 다름으로 인한 개발비용이 상승하는 등의 애로사항들이 있었고, 이로 인해 Web 환경에서의 가상, 증강, 확장 현실을 구현하기 위한 표준형 통합 플랫폼의 필요성이 대두하였다. OpenXR, WebXR이 가상 증강현실에서의 새로운 표준을 제시하고 기술을 공개하여, 하드웨어와 소프트웨어 산업 모두에서 좋은 호응을 얻기 시작하였다. 따라서 본 고에서는 가상 증강현실에서의 OpenXR과 WebXR 표준에 대한 정의 및 기술에 대하여 살펴보고, 가상 증강 환경에서의 기술 동향과 발전방향에 대하여 살펴보고자 한다.

  • 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.

  • Introduction of motion video including live video into network virtual reality systems makes virtual spaces more attractive. To handle live video in networked virtual reality s)'stems based on VRML, the scalability of networked virtual reality systems becomes very important on the internet where the performance of the network and the end systems varies dynamically. In this paper, a new quality control algorithm suitable for scalable networked virtual reality systems with live video capability is proposed. Our approach is to introduce the notion of the importance of presence (IoP) which represents the importance of objects in virtual spaces. According to IoPs, the degree of the deterioration of each object presentation will be determined in case of the starvation of system resources.

  • 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.

  • IT convergence technology is gradually becoming anthropocentric and evolving based on the low-carbon green growth. Augmented reality technique is a contents convergence technology that can mix virtual objects while maintaining a sense of the real world. For that reason, interaction between user and system is possible, can make various applications, and has a high possibility for expandability. To expand the scope of existing interaction, this paper suggests contextual UX-based augmented reality system. It is a system which creates virtual objects that respond to the changes in the real world environment, and users can directly apply their personal preferences to virtual objects. Also, several virtual objects can be registered all at once, and even shows animations corresponding to either day and night according to the brightness of illumination. As said, it improves user's satisfaction through a system of mixed usability, and leads to a continuous use of augmented reality contents.

  • 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.
