Recently, virtual reality (VR) and augmented reality (AR) have received increasing attention, with the development of VR/AR devices such as head-mounted displays, haptic devices, and AR glasses. Medicine is considered to be one of the most effective applications of VR/AR. In this article, we describe a systematic literature review conducted to investigate the state-of-the-art VR/AR technology relevant to plastic surgery. The 35 studies that were ultimately selected were categorized into 3 representative topics: VR/AR-based preoperative planning, navigation, and training. In addition, future trends of VR/AR technology associated with plastic surgery and related fields are discussed.

최근 수년 동안 벤츠, BMW등 많은 글로벌 제조업체는 증강현실 활용범위를 조립공정, AS, 전시장, 소비자 매뉴얼등 다양한 분야로 확산시키고 있다. 본 연구에서는 산업용 증강현실을 활용한 제조업의 혁신 프로세스 적용 현황을 파악하고, 이를 바탕으로 기존 ERP와 산업용 증강현실의 접목 가능성을 분석하였다. 또한, 산업용 증강현실 콘텐츠 개발에 있어서 전용 콘텐츠 개발 엔진의 선택이 개발 생산성에 가장 중요한 요인임을 실증적으로 분석하였다. 유니티3D로 개발한 동일 콘텐츠를 뷰포리아 스튜디오로 재개발하여 비교 분석한 결과, 개발 납기를 8배 빠르게 줄여주었다. 본 연구는 산업용 증강현실 콘텐츠를 2가지 엔진으로 실제 개발하여 직접적으로 생산성을 입증하는, 실제 구현하기 어려운 차별성을 가진 연구로써 유사 적용 산업분야의 많은 개발자에게 효율적인 개발도구 선택의 가이드가 될 것이다.

Currently the mobile augmented reality does not require supplemental hardware, such as markers like specific images or depth cameras, in order to acquire 3D environment information. This allows for increased accessibility and usability for the general user, and also broadened scope of development. The market research enterprise Counterpoint Research predicted that the growth of the augmented reality market will reach 70 trillion Korean Won by 2021. Application developments are also progressing. Wargaming, the developer of the global game World of Tanks, has launched an application that uses AR core at the GDC 2018. Thus, we must prepare for the impending augmented reality market and acquire top class augmented reality technology using 3D environment. This paper outlines the development of a game using AR CORE SDK to acquire 3D environment and Unity 3D game engine to combine camera images and 3D graphics, which all comes together to construct a natural augmented reality.

This study employs an experimental design to investigate the conditions under which the use of AR may be particularly effective or rather ineffective in advertising contexts. We first discuss the inconsistent results regarding the effectiveness of AR on advertising message comprehension and argue that these inconsistencies can be at least partly explained by the moderating effect of an individual's resistance to innovation (i.e., AR technologies). We then provide statistically significant interaction effects between ad types (AR-based, traditional 2D) and innovation resistance. Finally, we suggest that the effect of AR on certain variables is constrained or unconstrained by an individual's level of receptivity or resistance to a new technology-based advertising platform, and that flow experience is equivalent regardless of these levels.

In this paper, we explain the purpose of building a mobile app called "ARnetView" that can use the AR(augmented Reality)based calling function and AR based content creation function, and as well as an AR based data center that can share AR based video streaming and AR based contents on smartphones and tablet devices. For the AR(Augmented Reality) based data center implement, we have developed a mobile application and implemented a service system including an AR(augmented Reality) based calling function and AR based content production and AR based video streaming functions for real-time communication to connect a field technician and an expert so that the expert can see and discuss the situation in the field and technician and experts, they can draw digital annotation on mobile screen that accurately stick to 3D physical objects, allowing the expert to guide the technician step by step. In result, it provides a remote technical collaboration environment between field technician and expert. In addition, AR(Augmented Reality) collaboration service Platform was designed and implemented to increase work speed, efficiency, and utilization of advanced technicians, improve continuous productivity of equipment and facilities, maximize equipment and facility utilization, and strengthen industrial competitiveness. Therefore, through this, the AR collaboration service Platform can be applied to the industrial field, the medical field, and the entertainment/education field.

Augmented reality (AR) is considered to be an excellent user interface to a 3D information space embedded within physical reality. For this reason, it has been applied to various applications such as design, medical service, interaction, and collaboration. However, there is no formal way of analyzing the research trend and evolution of augmented reality. This paper identifies the research trend and change in augmented reality (AR) via co-citation analysis. The co-citation analysis provides how the AR research has evolved, who are main contributors, and which papers suggest essential and influencing impact. To systematically analyze the cocitation, we have retrieved 1,145 papers from the Web of Science and applied a scientomertric analysis using CiteSpace. Based on the co-citation analysis of authors and documents, it is possible to analyze the evolution of augmented reality, key authors and papers, and breakthroughs. We have also compared the proposed approach with survey papers written by experts so that the result of the co-citation analysis can compromise the qualitative result done by experts, and thus it can provide a different view and insight for visualizing the research on augmented reality.

Augmented reality is a technique for combining virtual images into real life by showing information of virtual 3D objects on top of a real-world environment (Azuma et al., 2001). This study is an augmented reality-based educational content delivery device that receives user input that selects either a preset object or a photographed object for augmented reality-based training; It includes a three-dimensional design generation unit that generates a stereoscopic model of the augmented reality environment from an object, a three-dimensional view of the scene, a disassembly process of the developing road from a three-dimensional model, and a content control unit provided by the user terminal by generating educational content including a three-dimensional model, a scene chart, a scene, a decomposition process, and a coupling process to build a coupling process from the scene to the three-dimensional model in an augmented reality environment. The next study provides a variety of educational content so that children can use AR technology as well as shapes to improve learning effectiveness. We also believe that studies are needed to quantitatively measure the efficacy of which educational content is more effective when utilizing AR technology.
