Augmented reality (AR) or virtual reality is suitable to apply the contents of a textbook so as to be directly observable by learners. This study aimed to examine the applicability and technology acceptance of anatomy learning using AR in nursing students. This study was conducted in May 2019 with 17 nursing students who studied an anatomy textbook using AR and answered a questionnaire about technology acceptance and the usability of AR in combination with the anatomy textbook. Perceived usefulness was identified as an influencing factor on technology acceptance with 51.2% acceptance rate and thus should be taken into consideration in the development of learning strategies using new technological learning methods.

This study defines the pipeline for digital fashion contents production using CLO 3D, a 3D fashion design software that supports virtual clothing visualization as a cutting-edge simulation technology for fashion, and vuforia, a mobile platform augmented reality (AR) development kit for creating AR applications. The proposed production pipeline is organized in a method to produce a virtual clothing model through CLO 3D software through works of patterns, sewing lines, textures, etc., and AR contents based on computer vision techniques using the functions and properties of vuforia development kits in the Unity engine development environment. In addition, we present application method that can be practically utilized from the perspective of practical users, such as fashion designers and directors, by creating a new type of AR digital fashion contents directly as a flow of the defined production pipeline.

This paper is a study on the production of mixedeality contents by realizing AR coloring technology, virtual environment, and VR devices by realizing the interaction in virtual environment. In this study, we designed and produced the content from a fairy tale called 'Cinderella' to produce and demonstrate real mixed reality contents. 'Cinderella' shows 3D modeling in the virtual space using the Oculus Rift, and the modeled shoes can be lifted using Leap-Motion. It is a virtual augmented interaction content for exhibition and experience that can move a specific range from the foot on the treadmill. In this paper, we try to share the experience of creating new mixed reality game contents, which is a mixture of augmented reality and virtual reality technology, and continuation of universal use of this field.

Recently, due to improvement of computer performance and development of information devices, technology of mobile augmented reality is proliferating rapidly. However, because most of contents are passive or limitary, user can not feel interest and immersion. This paper designs interaction user interface system of 2 dimensional drawing based on mobile augmented reality to make bi-directional communication between the real world and the virtual world possible by using the vision based augmented reality and the database system.

This paper presented an augmented reality based mobile application of maintenance and management for concrete bridges. For the development of augmented reality system, it was necessary to establish the concrete bridges detail information and history of maintenance that build the database of those. Also, the augmented reality based system required that concrete bridge information presented by the mobile smart phone. Therefore, this study developed an augmented reality based concrete bridge information mobile application-All about Bridge based on android smart phone and smart pad. The proposed All about Bridge application supports a various bridge informations simultaneously using smart phone and augmented reality technology.

메타버스 서비스란 '가상', '초월' 등을 뜻하는 영어 단어 '메타(Meta)'와 우주를 뜻하는 '유니버스(Universe)'의 합성어다. 현실세계와 같은 사회.경제.문화 활동이 이루어지는 3차원의 가상세계를 의미한다. 코로나 상황 속에서 비대면 소통의 수단 중 하나로 주목받으며 업무, 친목, 각종 행사 등 다양한 분야에서 활용되고 있다. 2022년 신년 사업 계획에서 메타버스 단어가 들어가지 않은 곳이 없다고 한다. 그만큼 핵심 키워드로 떠오르고 있다. 즉, 메타버스는 현실을 초월한 가상의 세계로 스마트폰, 컴퓨터 등 디지털 미디어에 담긴 세계를 뜻한다. 세상은 점차 바뀌어 가고 있다. 글로벌 통계 전문 업체 스태티스타는 2021년 307억 달러(약 35조 3265억 원) 규모이던 메타버스 시장 규모가 2025년에는 약 2969억 달러(약 341조 6428억 원)까지 커질 것으로 예측하였다. 현재 시장에서 통용되고 있는 메타버스에 대한 정의는, '현실세계의 사회·경제·문화적 활동이 유사하게 실현되거나, 현실에서 제공하지 못하는 경험을 제공하는 3차원 디지털 가상공간'으로 요약된다. 2021년의 메타버스는 더 이상 상상의 영역이 아니며, 현실세계 영역으로 침투하고 있는 것이다. 현실세계와 연결되는 가상세계, 실재감을 느낄 수 있는 가상공간이 점점 현실이 되어가고 있다. 1990년대 처음으로 등장한 메타버스 개념이 2020년대에 재부상 하였는데, 과거의 메타버스보다 몰입감과 실재감 있는 경험을 제공할 수 있는 XR 기술의 결합에 대한 기대감 때문이다. 지나온 30여 년간 메타버스가 뜨거운 주목을 받게 된 이유는 기술의 발전에 있다. 초고속인터넷 5G 상용화와 더불어 6G 출현, 가상현실, 증강현실이 일상에 스며들었기 때문이다. 이러한 기술 발달은 현실세계의 물리적 객체와 가상의 객체가 상호 작용할 수 있는 혼합현실까지 발전시키는 촉매제가 되었다. 여기에 지난 2년 동안 전 세계를 강타한 코로나19로 인해 비대면, 온라인 서비스가 확산되면서 메타버스는 개념이 아닌, 우리 일상의 한 부분으로 인정받게 되었다. 현재 우리 사회는 과거에는 불가능하다고 생각했던 사회적 거리두기, 재택근무, 온라인 수업 등을 진행하면서 이렇게도 사회가 돌아갈 수 있다는 것을 점차 느껴가고 있다. 더불어 현재 코로나로 인해 멀게만 느껴졌던 메타버스 세계를 반강제적으로 경험하고 있기도 하다. 이처럼 본 고에서는 최근에 나타난 메타버스를 이해하고 방송미디어(계)와 접목된 유형과 기술적, 서비스 사례를 파악하고, 주요 기업들의 추진 방향, 주요 시사점 및 결론으로 도출해보았다.

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

In this paper, we apply the learning of the mobile robot insect augmented reality Digilog Book. In the era of electronic, book written in paper space just have moved to virtual reality space. The virtual reality, constraints spatial and physical, in the real world, it is a technique that enables to experience indirectly situation not experienced directly as user immersive experience type interface. Applied to the learning robot Digilog Book that allows the fusion of paper analog and digital content, using the augmented reality technology, to experience various interactions. Apply critical elements moving, three-dimensional images and animation to enrich the learning, for easier block assembly, designed to grasp more easily rank order between the blocks. Anywhere at any time, is capable of learning of the robot in Digilog Book to be executed by the mobile phone in particular.

This paper is a study on map contents to be embedded in a new type of mobile device that combines 2D information and 3D information by combining 2D information with augmented reality technology. We also describe the planning and production of a 3D map application called 'NSU AR Map' using Unity3D engine to help understand this paper. 'NSU AR Map' is a map application that enables accurate identification of user's location and real-world view through 360 View. Based on the experience gained during the process of 3D map application, this paper will present how 3D technologies and augmented reality technologies are applied to new map applications and how they can be developed in the future.
