In this study, we developed the Field-Experiential Learning Framework Using the Location Based Mobil-learning System (LBMS) and it is mobile Augmented Reality (AR) for smart learning system which is advanced e-learning. AR is technology that seamlessly overlays computer graphics on the real world. LBMS-AR has become widely available because of mobile AR. Mobile AR is possible to get information from real world anytime, anywhere. Nowadays, there are various areas using AR such as entertainment, marketing, location-based AR. We analysed the result of survey and implemented the functions. Also, for survey about application's effectiveness, we have focus group interview (FGI). Then we demonstrated and explained the application to them. The result of survey about application's effectiveness shows that application have higher utilization in education area. One of the most promising areas is education. AR in education shows lifelike images to users for realism. It's a good way for improving concentration and attention. We utilize only a beacone for image-based AR without other sensor.

Development of AR/VR has expanded computer games from indoor static contents to outdoor dynamic contents. The syndrome of 'Pokemon Go' which is a representative AR game was born, and Nintendo's stock price shot up a massive 120%. Although some people gained profits, new damages are emerging including illegal intrusion or road accidents because it is a type of game to visit real locations. There are reported about 114 thousand road accidents related to the game. This study aims to examine the trends of AR game in 2016 and analyze damages and positive cases to suggest a method for preventing accidents due to the AR game, and a business model.

As AR display virtual technology enters public learning life extensively, the way in which reality and virtual connection are connected is also changing. The purpose of this paper is to study the expression between the 3D connection sensory information visualization experience and virtual reality enhancement through the visual direction sensory information visualization experience of the plane. It is analyzed by examining the basic setting method compared to the current application of AR display and flat visualization cases. The scope of this paper is to enable users to have a better experience through the relationship with sensory visualization, centering on eye tracking technology in the four categories of AR display connection design: gesture connection, eye tracking, voice connection, and sensor. Focusing on eye tracking technology through AR display interaction and current application and comparative analysis of flat visualization cases, the geometric consistency of visual figures, light and color consistency, combination of multi-sensory interaction methods, rational content display, and smart push presented sensory visualization in virtual reality more realistically and conveniently, providing a simple and convenient sensory visualization experience to the audience.

One of critical issues in the housing area is what strategies should be adopted for revitalizing contemporary communities in housing complex. It is expected that those strategies could encourage neighbourship and recover the existing community spaces. Based on the assumption that contemporary communities might have different characteristics from those of the traditional communities and spaces, this research aims to explore the possibility of new communities in a current context. With the development of the information communication technologies (ICT) and hardware systems, the environment would be capable of anticipating people's needs and then provide them with customization options to tailor the environment to their requirements. By incorporating the 'smart' paradigm, this paper introduces the concept of a smart community and space with the potential of mobile Augmented Reality(AR) as alternative strategies for activating the communities. The residents believe that existing common spaces need to be extendable and augmented by combining new technologies. The smart communities and spaces are expected to extend people's interaction to virtual world in aj real context, further combined with social network, it enables sustainable relationships among residents, contributina to a new type of community.

In this paper, we propose a hand gesture interface for the manipulation of augmented objects in 3D space using a camera. Generally a marker is used for the detection of 3D movement in 2D images. However marker based system has obvious defects since markers are always to be included in the image or we need additional equipments for controling objects, which results in reduced immersion. To overcome this problem, we replace marker by planar hand shape by estimating the hand pose. Kalman filter is for robust tracking of the hand shape. The experimental result indicates the feasibility of the proposed algorithm for hand based AR interfaces.

게임 문화는 오프라인에서 온라인으로 중심축이 급격하게 바뀌었다. 급격한 변화는 온라인 게임의 발전 불렀지만 게임 문화의 획일화를 불러 오프라인 게임 문화를 잠식하였다. 그러나 보드게임 활발한 보급은 사람들에게 과거의 추억과 사람사이의 유대감을 다시금 불러일으켰다. 그러나 지식의 부족으로 한정된 보드게임만 즐기게 되고 또한 구매하여 즐기기에는 경제적 부담이 컸기 때문에 인기가 많이 하락하고 있다. 본 논문은 이 문제를 해결하고 오프라인 게임의 장점을 살리기 위해 우리가 개발한 AR-Table System을 제안했다. 이 시스템은 오프라인 게임과 온라인 게임의 장점을 융합하고 단점을 보완하고 증강현실을 사용하여 새로운 게임 개발 환경을 제공한다. 이 시스템은 Main Table System과 Personal Display Device로 구성되어 있고, 물리적 마커를 응용한 디지털 마커를 개발하였다. 이 시스템을 설명하기 위해 보드게임 Geister를 AR Geister로 개발하였다.

The earthquake is a natural disaster causing loss of life or property damage and happens more often in Korea recently. Moreover, considering the increase of massive buildings, it is required to predict and visualize the information of the vibration in a building. In this paper, we developed a prototype framework to visualize the displacement information in the AR environments. In order to avoid the irregular halts of the scene and the unnatural distortion of the object, this framework uses the synchronization method at the scene update time and the interpolation of the sensor data for the displacement of vertices. In addition, we studied displacement estimation methods with the acceleration data to extend this framework to the system with accelerators.

The continuous development of in-vehicle information systems in recent years has dramatically enriched drivers' driving experience while occupying their cognitive resources to varying degrees, causing driving distraction. Under this complex information system, managing the complexity and priority of information and further improvement in driving safety has become a key issue that needs to be urgently solved by the in-vehicle information system. The new interactive methods incorporating the augmented reality (AR) and head-up display (HUD) technologies into in-vehicle information systems are currently receiving widespread attention. This superimposes various onboard information into an actual driving scene, thereby meeting the needs of complex tasks and improving driving safety. Based on the qualitative research methods of surveys and telephone interviews, this study collects the information needs of the target user groups (i.e., beginners and skilled drivers) and constructs a three-mode information database to provide the basis for a customized AR-HUD interface design.

현대인들의 인터넷 사용률이 지속적으로 증가함에 따라 소비자들은 오프라인 매장에서 의류를 구매하기보다 인터넷 쇼핑을 통한 구매를 선호하게 되었다. 그러나 온라인 구매로 인해 정확한 스타일 확인 불가 및 확신할 수 없는 사이즈로 큰 불편함을 겪고 있다. 따라서 최근 가장 떠오르는 기술 중 하나인 AR을 실생활에 적용하여 사용자가 매장에 가지 않고 집에서도 편하게 자신의 스타일링을 확인할 수 있도록 하는 AR 피팅룸을 구현하여 솔루션을 제안하고자 한다. 본 프로젝트에서는 3D 표현을 위해 Kinect Xbox 카메라를 사용하여 사용자의 신체정보를 추출한 후 unity와의 연동을 통해 사용자에게 편리함을 제공할 수 있는 AR-fitting 시스템을 설계하였다. 선택한 옷을 가상으로 입어 볼 수 있는 쇼룸 형태의 서비스를 제공하며 제스처 인식을 통해 보다 편리한 의류 선택 및 사이즈 조절 등을 가능하게 하였다. 또한, 사용자의 입력 정보에 따른 사이즈 측정 결과를 제공함으로써 사용자의 의류 구매를 보다 효과적으로 만들어 줄 수 있을 것이다.
