Virtual reality is being increasingly used for healing and therapy for mental health. In this study, we developed VR-based immersive content that enables virtual travel without the limitations of time and physical conditions. We aim to develop and produce VR content for relaxation and meditation using the beautiful natural scenery. To make realistic and immersive content, we took a video of natural sceneries with a small UAV connected to a VR camera. The content was developed through stitching, video editing and post-processing of the initially captured video data, and then the created VR video was inserted into the VR device. The produced content will be helpful for stress and used to heal the mind and body of exhausted modern people by providing the place with great scenery and sound in an immersive way at any time.

The aim of this study was to examine the trends (e.g., the distribution of the studies by year, country, research methods, and participants' education level) and fundamental findings [e.g., interaction in Virtual Reality (VR) environments, educational content through VR and Augmented Reality (AR) technologies, learning environment in AR, etc.] regarding immersive learning technologies such as VR and AR in English Language Teaching (ELT) between 2010 and 2019. Employing a systematic review research methodology, data was gathered from 59 academic articles published in the following databases: EBSCOhost, ERIC, Web of Science, and Taylor & Francis. The studies were analyzed using a content analysis approach, and findings demonstrated that immersive learning technologies in ELT came to prominence in 2017. Mixed methods research was the most widely employed research method. The most studied language skill was vocabulary for AR and speaking for VR. The results also revealed advantages and challenges with regards to the use of immersive learning technologies in ELT. Further analysis illustrated the findings related to characteristics of immersive learning technologies in ELT. Based on this review, research and design implications for researchers and practitioners are presented.

본 논문은 가상세계를 다루는 AR/VR 콘텐츠의 현실감 향상을 위한 몰입 요소를 연구한다. 이를 위해 선행적으로 몰입감 가상세계와 가상현실의 차이와 특징을 정리하였으며, 현재까지 개발된 가상세계의 현실감을 만들기 위한 몰입 요소에 대한 분석을 진행하였다. 몰입 요소를 감각 기관 중심으로 분류하여 크게 시각, 지각, 촉각, 청각 등의 감각적 몰입 요소와 기술적 몰입 요소를 나누어 연구하였으며, 이 요소 간의 상관관계를 살펴 몰입감 향상을 위한 콘텐츠 설계의 기준을 제한한다.

Recent improvements in technology have increased the consumption of virtual reality (VR) contents on immersive displays. The VR experience depends on the type of displays as well as the quality of VR contents. However, research on the impacts of VR content quality on VR experience and comparisons among different types of immersive display devices are lacking. In this study, VR contents created with our VR framework, are provided to participants on conventional two-dimensional (2D) immersive displays and VR headset. The geometric alignment of VR contents is improved with the addition of two calibration modes (i.e. preprocessing and straightening). The subjective feelings of presence and cybersickness experienced by participants while consuming VR contents created by our framework and commercial solutions are recorded in the form of questionnaires. The results of this study indicate that the improvements in VR quality lead to a better presence and less cybersickness in both conventional 2D displays and VR headset. Furthermore, the level of presence and cybersickness increases in VR headsets as compared to conventional 2D displays. Finally, the VR content quality improvements lead to a better VR experience for our VR framework as compared to commercial solutions.

본 논문은 멀티플레이어 VR 게임에 나타난 플레이어 참여방식의 비균질성에 주목하여, 그 함의를 규명하는 데에 목적을 둔다. 비균질성이란 멀티플레이어에게 몰입형 VR과 비몰입형 VR을 혼재하여 제공하는 방식을 지칭하는 개념이다. 최근 HMD와 같은 몰입형 VR 장치의 상용화에 따라, <더 플레이룸 VR>처럼 비균질 멀티플레이 방식을 채택한 게임이 점차 대두되기 시작했다. 이에 따라, 본고는 비균질 멀티플레이에 맞춰 수정 및 개선한 MDA 프레임워크를 통해 <더 플레이룸 VR>을 분석하였다. 그 결과, 비균질 멀티플레이는 인터페이스에서의 분리에서 그치지 않고, 플레이 양상과 경험 자체까지 상이하게 만듦을 확인할 수 있었다.

The majority of construction site incidents occur due to a lack of hazard awareness among workers on job sites. This lack of awareness is despite mandatory construction safety training, typically in the form of written content (safety manuals) or of images depicting hazards. To reduce job-site injuries and fatalities, general contractors have started adopting Virtual Reality (VR) to impart safety training to job site personnel. VR safety training can take the form of an immersive simulation comprising potential safety hazards intentionally embedded into a virtual job site; users are required to identify these hazards within a specified time frame with the expectation that they will be more adept at recognizing hazards on an actual job-site, resulting in fewer accidents. This research study seeks to identify the actual impacts of VR on construction safety awareness among participants. The research addresses the following question: Does VR improve hazard recognition awareness? The primary objective is to evaluate participants' performance of past construction safety awareness against present construction safety awareness after receiving VR training. Participants were asked to complete a multiple-choice Qualtrics™ questionnaire. The results of the study showed a statistically significant knowledge gain advantage with respect to hazard recognition and construction safety awareness with the use of interactive, immersive VR over a more conventional and passive safety training method.

This study intends to propose an evaluation tool for analyzing the sense of immersion of realistic VR game contents in the metabus game industry, which is rapidly increasing recently. This paper presents an analysis tool to measure the degree of immersion after selecting three types VR games for research, and analyzing the immersion way method of the game. The research method analyzes how the user and the sense of immersion formed in the storytelling in the game can have an effect. Based on the results, we present an sense of immersion analysis and measurement method for evaluating the usability of VR game contents, which is a key element in the metaverse era. Furthermore, it expands the immersion element that appears in storytelling to the game industry and seeks a new direction of development through connection with the VR game industry.

본 연구는 VR 콘텐츠를 사용해 본 이용자의 VR 사용현황과 함께 도서관에서 VR 콘텐츠 서비스를 제공하는 것에 대한 이용자 요구를 규명하는 것을 주요 목적으로 수행되었다. 온라인 설문조사를 수행한 결과 총 229명의 VR 콘텐츠 사용 경험자가 응답하였으며, 기술수용모델 분석 결과 VR 콘텐츠에 대한 이용자 유용성 및 이용용이성 인식과 VR 콘텐츠에 대한 이용자 만족 및 재사용 의도 간의 관계에 대해 모형 적합도가 양호한 결과를 보여서 도서관에서 VR 콘텐츠 서비스 만족도를 높이기 위해서는 이용자에게 VR 콘텐츠 사용편의성을 개선하고, 몰입감을 높일 수 있는 환경을 조성하여야 함을 보여주었다. 또한 응답자들은 VR 콘텐츠 서비스가 도서관 이용자 만족도와 도서관 재방문 의도를 높일 것으로 응답하였으며, 선호하는 VR 콘텐츠 주제로 게임(액션, 전략 등), 여행, 우주/해양의 순서로 답변하였다. 도서관에서 VR 콘텐츠 서비스를 제공하는 것에 대체로 긍정과 기대에 대한 의견이 많았지만, 효용성이 그리 크지 않을 것 같고 기기관리가 제대로 되지 않을 것이라는 부정적 의견 또한 제시되었다.

Purpose: This study started with the question of how to use Virtual Reality (VR) contents as a part of the non-face-to-face education tool that has recently attracted attention. Methods: In this paper, the use of VR contents as an educational tool is explained as a process of 'new media access dimension'. The question was explored on why Virtual Reality (or Augmented Reality) contents are not used as educational tools in the educational field. Results: As a result, the lack of 'material access' such as devices and infrastructure affects 'motivational access' approach stage, which is the previous stage. Again, it has a negative effect on literacy, which is 'skill access' approach stage. As it was found that it was not circulating to the level of "motive-material-skill-usage", it was discussed that it was taking a different step from the past adoption process of ICT and smart media. Conclusion: Based on this, it is believed that immersive content will contribute to arousing interest that can be applied and spread in the educational field, and it is also thought that it will be possible to derive academic interest in the educational effect according to the characteristics of immersive content such as VR.

실감형 콘텐츠는 사용자의 오감을 극대화하여 실제와 유사한 경험을 제공하는 콘텐츠로 가상현실, 증강현실, 혼합현실 등이 이에 속한다. 실감형 콘텐츠에서 사용자에게 실재감을 제공하기 위해서는 실제와 같은 시각적 이미지와 청각, 촉감 등을 제공해야 한다. 그러나 실감형 콘텐츠를 개발하기 위한 급격한 환경 변화로 인해 인력 양성 교육 전문가는 교육 과정 설계에 어려움을 겪고 있다. 본 연구에서는 실감형 콘텐츠 인재 양성 전문가에게 도움을 주기 위해 드론을 활용하여 실세계 측정 데이터를 취득·가공하고, 도출된 데이터를 VR/AR/MR에 적용하는 일련의 교육 과정을 제안한다. 설계 과정은 기업과 학생, 지역 사회에 대한 수요조사와 분석을 통해 교과과정을 구성한다. 본 연구는 실감형 콘텐츠 인력 양성을 시도하려는 교육 전문가에게 유익한 자료가 될 수 있다.
