Myanmar, also known as Burma, has a rich cultural heritage, and its historical tourist attractions well known around the world. Therefore, we designed and developed an interactive spatial augmented reality (iSAR) book on the cultural heritage of Myanmar. This iSAR book has total of 18 pages with rich media content including videos, animations, audio, and images featuring the cultural heritage of Myanmar in a digital format. In addition to virtual content, navigational features such as virtual buttons and touch-based hand gestures were implemented using Leap Motion and VVVV. Therefore, the developed iSAR book allows virtual content and navigational features to merge seamlessly into a physical book. Five participants were recruited to evaluate the prototype iSAR book, and interviews were conducted to gather their feedback based on its immersive qualities. Thus, the developed iSAR book on Myanmar effectively shares the cultural heritage of Myanmar, and ultimately allows users to explore and gain more insight into the country.

The system performance of Engineered Safety Features is of utmost importance in a nuclear power plant. The human performance is identified as most critical to assurance of the optimal operability of safety systems during an emergency. The aim of this study is to determine how the performance of safety system could be evaluated using Augmented Reality technology. The paper presents a description of how a systems engineered approach could be used to develop the necessary operating conditions needed to conduct this measurement. Augmented Virtual Reality (AVR) interface technology is achieving ease of availability and widespread use in many applications today as illustrated by the launch of several AR and VR devices aimed at media consumption. As such, environments that incorporate such AVR hardware have become invaluable tools in designing human interface systems because of the high fidelity and intuitive response to natural human interaction that can be achieved [2]. The outcome of the measurement undertaken is to determine whether 1.) Operator(s) performance can be enhanced by introducing an improved cognitive method of monitoring plant information during an Emergency Operating Procedures (EOP) and 2.) In correlation, inform the performance of the diverse safety systems on the basis of human factors.

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.

Purpose To develop an educational program using virtual reality (VR) and augmented reality (AR) in oriental medicine education, this study investigated the status of programs currently being used mainly in the fields of medicine, nursing, and dentistry, and was the basis for developing an oriental medicine education program. We plan to use this for future research purposes. Methods To investigate medical simulation education using VR and AR technologies, 72 studies were searched using the ProQuest Central Database (period 1.1.2000 to 10.10.2023.) Of these, 22 were selected for analysis. Results Among the selected studies, the educational fields of the program were 59% (13 studies) in medicine, 32% (7 studies) in nursing, 9% (2 studies) in dentistry, 73% (16 studies) were VR in terms of applied technology, and 27% (6 studies) in AR. Conclusions Recently, research on VRand AR has increased in the medical field. As patient rights and medical environments change, clinical practice education programs using new technologies are needed, in addition to traditional face-to-face practice. Related research is expected to be active in the field of Oriental medicine in the future.

Virtual reality (VR) and augmented reality (AR) technologies can interact intuitively using virtual 3D images. Information signs on buildings that are frequently used by the public play a very important role in conveying information. However, the current information sign has different understanding and interpretation, and it is difficult to communicate quickly and intuitively for interaction. The purpose of this study is to increase the efficiency of information signing through information provision using mobile augmented reality. The InfoAR app not only guides you to the destination of the building, but also acts as a marker for the logo image. The logo image created based on the feature points recognizes the information of the destination. It is converted to AR through a mobile app, allowing users to easily find their destination by obtaining specific information. In addition, it presents interactions that can enlarge, reduce, move, and rotate information about virtual objects augmented through a function called AR. In the future, if user convenience and usability of the interface are added, research is conducted, and the level of completion is improved, such as using VR contents and promotions and business cards, it is expected that highly useful contents will be produced.

최근 홈 쇼핑 이용자의 수가 급증하면서 각 매장에서는 소비자의 눈높이에 맞는 서비스를 제공하기 위한 많은 노력들이 있어왔다. 특히 의류 관련 매장에서는 온 오프라인에서 소비자들의 취향에 맞는 의상들을 실시간으로 체험해볼 수 있는 증강현실 기술 기반의 가상 피팅룸에 대한 연구가 진행되어왔으며 일부에서는 이미 서비스를 진행하고 있다. 이를 위해서는 일반적으로 OpenCV, 증강현실용 API 및 Kinect 등과 같은 시스템을 사용하여 사용자 인터페이스를 구축한다. 그러나 장비가 고가라는 단점을 가지고 있다. 그러므로 본 논문에서는 일반 가정에서도 특별한 장비 없이 쉽게 시뮬레이션해볼 수 있는 OpenCV 및 libsigc$^{++}$을 사용한 증강현실 기술 기반의 3D 가상 피팅룸 시뮬레이터를 개발한다. 본 시뮬레이터는 홈 쇼핑뿐만 아니라 온 오프라인 매장에서 매우 효율적으로 사용할 수 있을 것으로 판단된다.

최근 증강현실 기술을 이용하여 시공 전의 건축물이나 복원 중인 문화재를 확인하기 위한 연구들이 진행되어 왔다. 기존의 연구들은 특수 장비를 사용하거나 실외의 장거리에서 사용이 어려운 마커를 사용하였으며, 매번 서버에서 가상 객체의 변환을 계산하므로 서버 부하가 우려되기도 한다. 본 논문에서 제안하는 모바일 증강현실 시스템은 휴대폰의 GPS와 가속도 센서를 이용하여 마커 없이도 사용자의 위치 및 방향을 판단하며, 최대한 서버의 부하가 적도록 설계하였다. 서버는 클라이언트로부터 얻은 GPS의 위치정보와 카메라의 영상정보를 미리 정의되어 있는 3D 객체와 비교를 하여 위치와 방향을 판단한다. 그리고 계산된 위치와 방향의 가상 건축물 정보와 정합정보를 클라이언트로 전송하면 이를 받아 카메라 영상 위에 정합한다. 이후에는 서버와 추가적인 접속 없이 클라이언트 내에서 가속도 센서로 감지한 사용자의 움직임에 따라 가상 건축물의 변환을 수행할 수 있다.

Nowadays personal users create a variety of multi-media contents and share them with others through various devices over the Internet since the concept of user created content (UCC) has been widely accepted as a new paradigm in today's multi-media market, which has broken the boundary of contents providers and consumers. This paradigm shift has also introduced a new business model that makes it possible for them to create their own multi-media contents for commercial purpose. This paper proposes a tangible virtual studio using augmented reality to author multi-media contents easily and intuitively for personal broadcasting and personal content generation. It provides a set of tangible interfaces and devices such as visual markers, cameras, movable and rotatable arms carrying cameras, and miniaturized set. They can offer an easy-to-use interface in an immersive environment and an easy switching mechanism between tangible environment and virtual environment. This paper also discusses how to remove inconsistency between real objects and virtual objects during the AR-enabled visualization with a context-adaptable tracking method. The context-adaptable tracking method not only adjusts the locations of invisible markers by interpolating the locations of existing reference markers, but also removes a jumping effect of movable virtual objects when their references are changed from one marker to another.
