현대 사회의 무선 서비스 매체로 스마트 폰이 부상되고 있는 가운데 다양한 서비스들이 융복합된 모바일 서비스들이 소개되고 있다. 특히 모바일 SNS (Social Network Service)는 위치 기반으로 실세계 내의 인적 네트워크를 극대화 가능한 서비스로 주목받고 있다. 본 논문에서는 트위터의 Twitter4j OpenAPI를 이용하여 안드로이드 기반의 모바일 SNS와 증강현실 응용 연동 시 효율적 인터페이스를 위하여 CameraPreview기반의 SNS 인터페이스를 구현하였다. 일반적인 브라우저 기반의 SNS와는 달리 구현된 시스템의 인터페이스는 사용자에게 SNS 이용 중 현실 세계에 대한 뷰를 제공함으로 차후 현실세계의 데이터 파싱과 입력 및 실시간적 증강 현실 응용 연동의 가능성을 보여준다.

In this paper, an implementation method of augmented reality (AR) technology using Web 3.0 information services in the field of disaster response is proposed. The structure and characteristics of semantic web-based Web 3.0 are realized and a AR based mobile visual search (MVS) applied in the disaster sites is described. Based on Web 3.0 and AR MVS, a semantic web ontology oriented configuration scheme for disaster-related information and the communication scheme of information provided by AR technology are proposed. For the purpose of providing disaster-related and customized information to the disaster response site quickly and accurately, a method of leveraging Web 3.0 information services in AR technology is presented.

최근 증강현실의 관심이 높아짐에 따라 다양한 분야에 증강현실을 접목시키려는 시도가 일어나고 있다. 따라서 본 논문에서는 모바일 증강현실을 이용하여 이용자에게 차량 부품에 대한 정보와 간단한 정비 방법을 제공하는 시스템을 제안한다. 구현에 있어서 Unity 3D와 증강현실 라이브러리 Vuforia를 사용한다. 본 논문에서는 알고리즘의 복잡도가 낮고 안정적이며 구현이 간편한 마커를 사용하여 3D 좌표를 추출한다. 사전에 차량 각 부품에 맞게 마커를 제작하여 등록한 뒤 부착된 마커를 모바일 카메라로 인식하여 지정된 3D 좌표에 텍스트, 이미지 및 동영상을 띄워 제공한다. 이렇게 제작된 시스템은 어플리케이션 사용자에게 보다 직관적으로 자동차에 대한 정보와 간단한 정비 방법 등을 제공할 수 있으며 나아가 차량 정비 교육 등에도 충분히 활용 가능할 것으로 예상된다.

With the increased market demand for advanced specifications in smart phones, smart phones that have functions with wireless communications with high speed, cameras with high pixel and with high graphic processing ability have appeared. Furthermore, as traditional Augmented Reality technology has been practicable in mobile devices, many application's use AR technology, so AR's portability has been increased. But application with AR technology, which was implemented in smart phones has created capacity issues as applications are taking up a large portion of the memory capacity of phones. This research designed and implemented optimized AR technology by Mixare, AR open source, to solve such problems. As a result, I assured that there has been a decrease in application's memory used on the basis of mobiles.

This paper presented an augmented reality based mobile application of maintenance and management for concrete bridges. For the development of augmented reality system, it was necessary to establish the concrete bridges detail information and history of maintenance that build the database of those. Also, the augmented reality based system required that concrete bridge information presented by the mobile smart phone. Therefore, this study developed an augmented reality based concrete bridge information mobile application-All about Bridge based on android smart phone and smart pad. The proposed All about Bridge application supports a various bridge informations simultaneously using smart phone and augmented reality technology.

In this paper, we propose a deep learning based on-device augmented reality (AR) system in which multiple input images are used to implement the correct occlusion in a real environment. The proposed system is composed of three technical steps; camera pose estimation, depth estimation, and object augmentation. Each step employs various mobile frameworks to optimize the processing on the on-device environment. Firstly, in the camera pose estimation stage, the massive computation involved in feature extraction is parallelized using OpenCL which is the GPU parallelization framework. Next, in depth estimation, monocular and multiple image-based depth image inference is accelerated using the mobile deep learning framework, i.e. TensorFlow Lite. Finally, object augmentation and occlusion handling are performed on the OpenGL ES mobile graphics framework. The proposed augmented reality system is implemented as an application in the Android environment. We evaluate the performance of the proposed system in terms of augmentation accuracy and the processing time in the mobile as well as PC environments.

Recently, local game companies have been increasingly producing PC-based game that were popular with users among the existing commercialized games into mobile games through remakes. In this paper, we studied how console-based game influenced mobile augmented reality game . Through this process, we extracted five characteristics of mobile augmented reality, then interpreted and classified the meaning of this. Based on released in 2016, the scope of research is limited to console and mobile games previously released. According to the analysis, showed 50 characteristics and borrowed 78% from its existing Pokemon, 22% from its new production, and contained 24% reality. We also found that the Pokemon game series , and the exotic series had much influence on production. Based on this research data, we hope that augmented reality games for mobile will be made more active using existing game contents. It is also hope that such activities will lead to the growth of the home and abroad game industry.

As the augmented reality market has rapidly grown in recent years, various platform interfaces have emerged. In addition, it provides recommended travel information for each user based on a smartphone. Based on the recommended travel information, it provides the information of a tour path. Even though it is implemented in mobile devices and does not have continuous communication with servers, it needs new technologies that can provide additional entertainment services such as cultural and historical sites in corresponding regions while still providing guides depending on user movements
