Augmented reality is used in various fields such as culture, education, military, medical. This is a method of recognizing information of an augmented object on the camera. Exhibitions and educational contents for children are already produced in various ways. This research showed the developed contents deliver cultural property information using augmented reality. 'Galgibi AR' and 'Jang Young-sil's Invention AR' allow you to experience cultural assets up close. 'Galgibi AR' is the experience content in the form of 3D blocks. It makes to understand the structure of the zeolite, Galgibi. 'Jang Young-sil's Invention AR' make you to watch out four objects in detail by zooming in, zooming out and rotating. It can also take pictures with the inventions. Both contents implement what we want to deliver accurately through simple content. They increase the enjoyment of cultural heritage through experience contents. This research addressed to help the cultural property information spread to the public by using Augmented Reality.

New Fabrication Facility (FAB) construction is performed with Building Information Modeling (BIM) based design. The BIM design data keep updated during the FAB construction. To improve fast-track construction management, a Fabrication Facility Augmented Reality (FABAR) was developed. This study introduces a FABAR system development process and shows performance evaluation results of the FABAR prototype system. The FABAR is implemented with three major modules: Augmented Reality (AR) visualization unit (Room-box) to transfer big BIM data to AR data, AR registration and tracking unit to match AR with real scape and to keep AR coordination in real, and AR data management unit to enhance usability. The prototype performance results were as follows: visualization of design BIM data via AR within 24 hours, precise AR registration and tracking registration, and appropriate usability to support FAB construction management at site. The results indicate that the FABAR is applicable for FAB construction management. Especially, the BIM data transformation method using Room-box in this study signifies a new construction management approach using fluctuating BIM design data in the fast track construction condition.

In these days, technologies of virtual reality (VR) and of augmented reality (AR) have applied to diverse areas such as medicine, defense, education that are closely related to real-life practice. In contrast to the previous applications of game or sports, the technologies of VR and AR tends to expand the areas of applications according to development of the imaging or video techniques. This paper introduces VR and AR techniques and some examples of applications. In addition, this paper introduces how the differences between VR and AR technologies affect to the applications of broadcasting systems. In the last, this paper introduces the results of interviews about suitability and future feasibility of VR and AR techniques for broadcasting systems from korean broadcasting companies.

The tourism industry and AR act as important factors to diversify the tourism industry by combining them with one another. Currently, the advent of mobile smartphones and AR interactive is expected to play a major role in improving tourists' experiences and promoting tourism. AR's high entertainment characteristics, realism and strong interaction can be actively used as a major advantage in promoting tourism. This paper presents some appropriate examples of how AR interactive design is used in tourism marketing through various use cases where AR interactive design is used in tourism. Furthermore, a detailed analysis of the Magical Gulangyu verifies the descriptions listed in the text and presents the direction of future research.

In this paper, we propose that we can use our mobile devices as an effective interface for HMD-based augmented reality(AR) applications. Recently most People have mobile devices, with which they usually watch movies and connect internet So, people get accustomed to the mobile devices. In addition, the mobile devices can show various markers on their displays so that we can implement various AR applications. So, the mobile devices are quite good interface for AR applications. In the paper, we show how we can use the mobile devices as Interface for AR applications by implementing some AR experiments.

Modern technology offers many ways to enhance teaching and learning that in turn promote the development of tools for educational activities both inside and outside the classroom. Many educational programs using the augmented reality (AR) technology are being widely used to provide supplementary learning materials for students. This paper describes the potential and challenges of using GeoGebra AR in mathematical studies, whereby students can view 3D geometric objects for a better understanding of their structure, and verifies the feasibility of its use based on experimental results. The GeoGebra software can be used to draw geometric objects, and 3D geometric objects can be viewed using AR software or AR applications on mobile phones or computer tablets. These could provide some of the required materials for mathematical education at high schools or universities. The use of the GeoGebra application for education in Laos will be particularly discussed in this paper.

Current two-dimensional (2D) augmented reality (AR) devices present virtual image and information to a fixed focal plane, regardless of the various locations of ambient objects of interest around the observer. This limitation can lead to a visual discomfort caused by misalignments between the view of the ambient object of interest and the visual representation on the AR device due to a failing of the singular fusion. Since the misalignment becomes more severe as the depth difference gets greater, it can hamper visual understanding of the scene, interfering with task performance of the viewer. Thus, we analyzed the range of singular fusion (RSF) of AR images within which viewers can perceive the shape of an object presented on two different depth planes without difficulty due to the failure of singular fusion. It is expected that our analysis can inspire the development of advanced AR systems with low visual discomfort.
