Because the lessons of 'our body' are based on indirect experiences and simple experiments, various methods are needed to improve the learning effect. In this study, seventeen AR contents were created to be used in five subjects in the 5th grade elementary school. The learning contents implementation were made using QCAR (QualComm's Augmented Reality) and Unity 3D (Unity 3D) program, which are augmented reality software development kits (SDKs). In order to find out the applicability, we applied the developed contents to one grade 5 classroom equipped with internet environment. Participants were asked about their perception of the program and interviewed. As a result, the developed AR learning contents appeared to be available. It was expected to help improve learning and was pointed out that improvement of internet condition and development, also, was needed expansion of various contents should be complemented.

Augmented Reality (AR) is an emerging technology and a vibrant field, it has become common in application development, especially in smartphone applications (mobile phones). The AR technology has grown increasingly during the past decade in many fields. Therefore, it is necessary to determine the optimal approach to building the final product by evaluating the performance of each of them separately at a specific task. In this work we evaluated overall CPU and RAM performance for several types of Markerless Augmented Reality applications by using a multiple-objects in mobile development. The results obtained are show that the objects with fewer number of vertices performs steady and not oscillating. Object was superior to the rest of the others is sphere, which is performs better values when processed, its values closer to the minimum CPU and RAM usage.

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.

Makkah Al-Mukarramah is the capital of Islamic world. It receives special attention from the Saudi government's rulers to transform it into a smart city for the benefit of millions of pilgrims. One of the 2030 vision objectives is to transform specific cities to smart ones with advanced technological facilitation, Makkah is one of these cities. The history of Makkah is not well known for some Muslims. As a result, we built the concepts of our application "Ain Makkah" to enable visitors of Makkah to know the history of Makkah by using technology. In particular "Ain Makkah" uses Augmented Reality to view the history of Al-Kaaba. A 3D model will overlay Al-Kaaba to show it in the last years. Our project will use Augmented Reality to build a 3D model to overlay Al-Kaaba. Future work will expand the number of historical landmarks of Makkah.

Visualized information platforms through building information modeling (BIM) such as virtual reality (VR) and augmented reality (AR) improves the efficiency of architectural information exchange. Despite that, less effort has been directed to evaluate the effectiveness of different BIM visualization platforms for architectural design review. This study fills these gaps and compares three BIM visualization tools for reviewing diverse architectural review factors and technology acceptance degree. Three main BIM visualization tools, which are desktop-based, virtual reality-based and augmented reality-based, were employed and different architectural review factors and user's technology acceptance degree was measured. As a result, VR and AR environment showed better visual presentation than desktop environment during design review. In terms of the technology acceptance level, VR and AR environments have received higher ratings compared to desktop environments. The detailed findings provide guidelines for participants and researchers involved in design review process to selectively adopt VR and AR system to various architectural design review components.

There are a variety of apps that are finding their way. And in car navigation, we launched a product that reflects Augmented Reality technology this year. However, existing apps have problems. It is implemented in 2D or 3D, has a large error range because it has been modified in most vehicles, is not updated in real time, and car augmented reality navigation is a vehicle, and a separate device is required, etc. In this study, we implemented a smartphone app for walking directions using augmented reality, and made it possible to intuitively use a route service from a user 's location to a destination. The Dijkstra algorithm is applied to calculate the shortest path to solve the problem of finding the route with the least cost. By using this application, it is possible to use the route search service even in a data-free environment, to solve the inconvenience of the language barrier, and to update in real time, so that the latest information can be always maintained. In the future, we want to develop an app that can be commercialized by using a character in the path to promote it.

Along with a variety of coding education, physical computing education for controlling various sensors is being actively conducted for elementary, middle, and high school students in line with the era of the fourth industrial revolution. A problem with physical computing education using Arduino is pin connection errors between Arduino and various sensors. Most of the students who come into contact with the Arduino for the first time often do not know the purpose of the Arduino pin and the connection position of the pin. Also, hardware built with incorrect pin connections to the Arduino board often does not work properly. If this case continues, students will lose interest in coding education. Therefore, in this paper, we implemented an augmented reality application that informs the connection process of the Arduino board and the sensor during physical computing coding education using Arduino, and designed and implemented educational content for the Arduino pin position and connection process. First, we explain the role of the Arduino board and the sensor and the location of the pins. After that, the students run the educational augmented reality educational content using their smartphones and check the correct pin connection process between the Arduino and the sensor. In the physical computing education, augmented reality content is used to increase the understanding and immersion of the class. It is expected that the educational effect will also increase by inducing fun and interest in physical computing coding education.
