Recently as AR(Augmented Reality) is focus of attention, AR is applied to various fields and is expected its valuable use. In this paper, we suggested the method to combine existing e_Book with augmented reality technology based on mobile equipment. We ascertained that augmented reality contents implemented on PC work well in pITX embedded lines (CPU Intel ATOM Z530) and we implemented augmented reality using marker in e_ Book in pITX embedded lines through these experiments. As the result of it, we could show the contents at the same time which had difficulty to be expressed on e_Book before. Also the existing augmented reality contents could be used as it is. Finally we expected that the user could interact with virtual contents or services directly and intuitively in the real world.

Recently augmented reality technology has been researched to view the virtual shape of buildings before construction or cultural heritages under recovery. Those researches used special devices or markers that are not applicable in long distanced outdoor environment. Also the server had to compute a lot of transformations for the location changes of virtual objects. This paper proposed a mobile augmented reality system that uses GPS and accelerometer sensors in order to compute the virtual object's locations without using markers. The server determines the position and orientation by comparing the GPS data obtained from the client with the predefined 3D object informations in the server. If the server sends the virtual object informations such as the position, orientation and matching information, then the client matches the virtual object on the screen of mobile camera phone. In addition, the client computes the transformations of location change detected by the accelerometer derived from the user's movement without additional connection to the server.

The popularity of smart devices and Location Based Services (LBSes) is increasing in part due to users demand for personalized information associated with their location. These services provide intuitive and realistic information by adopting Augmented Reality (AR) technology. This technology utilizes various sensors embedded in the mobile devices. However, these services have inherent problems due to the devices small screen size and the complexity of the real world environment; overlapping content on a small screen and placing icons without considering the user's possible movement. In order to solve these problems, this paper proposes a Mobile Augmented Reality Model with the application of Street Data. The model consists of two layers: "Real Space" and "Information Space". In the model, a user creates a query by scanning the nearby street with a camera in real space and searches accessible content along the street through the use of the information space. Furthermore, the results are placed on both sides of the street to solve the issue of Overlapping. Also, the proposed model is implemented for region "Aenigol", and the efficiency and usefulness of the model are verified.

In this paper, we developed an augmented reality learning tool suitable for chemical bond learning and proposed a process-oriented guided inquiry learning using mobile augmented reality (POGIL-MAR) to find out how it affects science achievement, science learning motivation and learning flow. Participants were 139 10^th-grade students from a coeducational high school in Gyeonggi-do, and they were randomly assigned to the control group (TL), the treatment group 1 (POGIL), and the treatment group 2 (POGIL-MAR). They learned the concept of the chemical bond from the Integrated Science subject for four class periods. Results of two-way ANCOVA revealed that the POGIL-MAR group scored significantly higher than the other groups in a science achievement test, science learning motivation test, and learning flow test, regardless of their prior science achievement. In addition, in the case of the low-level group, the POGIL-MAR group showed a statistically significant improvement in achievement compared to the TL and POGIL groups. The MANCOVA analysis for sub-factors of science learning motivation show that the POGIL-MAR group had significantly higher scores in intrinsic motivation, career motivation, self-determination, self-efficacy, and grade motivation. In particular, the interaction effect between the teaching and learning method and the level of prior achievement was significant in the intrinsic motivation. Meanwhile, the MANCOVA analysis for sub-factors of learning flow show that the POGIL-MAR group had significantly higher scores in clear goals, unambiguous feedback, action-awareness merging, sense of control, and autotelic experience. Based on the results, educational implications for effective teaching and learning strategy using mobile augmented reality are discussed.

모바일에서의 증강현실(Augmented Reality :AR) 어플리케이션은 디바이스의 구조상 많은 제약사항이 있기 때문에 데스크탑 환경에 비교하여 접근성이 낮다. 이러한 문제점을 해결하기 위해 다양한 방법의 연구가 진행되고 있다. 본 논문에서는 모바일 기기의 처리량을 줄이기 위해 프로그래밍 가능한 GPU(Graphic Processing Unit)를 이용, 영상처리 알고리즘을 병렬로 처리하고 고속화하여 모바일 AR 어플리케이션의 접근성을 높이는 비마커(Markerless)기반 객체 인식 시스템을 구현한다.

This research discusses user's context based design methodology for location-based AR contents design. A media contents regarding mobile service should be designed considering user's context in dynamic environment. In this regard, I would like to suggest user's context centered design method for augmented reality contents. There are two different research methods in conventional context-based design method. This research tries to totalize two methods. In this sense, this research investigated previous researches which make a new design method. And then, context-based design methods are compared and the pros of them are integrated so as to create a new context-based design method. This new methodology aims to be an effective design method of creating AR contents in the future.

Recently, as AR(Augmented Reality) technology develops, it is used in field of diverse industry and specially affects structures and human interaction in field of architecture. This paper proposes 3D visualization application for realistic experience of structures by using outdoor AR technology. Proposed application visualizes structures such as high buildings, bridges, ships, and so on to be constructed in future, considering ambient environment by using outdoor AR technology, provides precisely user structures after completing construction and offers more realistic information and immersion as compared with previous methods.

Recently, various methods have been studied and developed to develop the local cultural contents industry. This research has produced a mobile AR augmented reality game that anyone can easily access by developing contents that can be enjoyed with new tourists. It aims to spread 10 million tourists to surrounding tourist attractions by developing a new storytelling-based AR game using the symbol of Jeonju, which is the birthplace of the Joseon Dynasty, and promote economic value-added activities in nearby stores. GPS technology and AR marker-based action augmented reality games will be newly established as cultural contents based on new regional scenarios. Augmented reality games that combine visual resources are increasing values of local brands by playing games at Jeonju tourist attractions.
