Currently, there are many augmented reality content, but little has been commercialized that two or more terminals communicate in real time and use at the same time. In this paper, we are going to study the possibility of network augmented reality contents using Bluetooth communication. Through this research, network augmented reality development and contents will be expanded further.

4차 산업혁명 시대의 핵심 기술 분야라고 불리는 가상현실(Virtual Realityl VR)/증강현실(Augmented Reality; AR) 기술은 그 동안 IT 시장을 주도해 온 스마트폰 시장이 포화상태에 도달함에 따라 주요 IT기업들의 차세대 비즈니스로 떠오르고 있으며, 미디어 플랫폼인 VR에 대한 연구 또한 계속해서 진행되고 있다. 또한 최근 들어 디스플레이 해상도가 높아지고 PC의 성능이 좋아지면서 많은 회사에서 VR 콘텐츠에 대응하여 VR기기를 출시하고 있다. 하지만 아직까지 VR에 대한 호환성 테스팅 방법은 제대로 제시되지 않고 있는 실정이다. 따라서 본 논문에서는 연구를 통해서 효과적이고 효율적인 호환성 테스트 방법을 제시한다.

Entering the digital cinema era, movies and games are remediating each other. The shots of digital movies are being transformed into realistic content through digital Moving long-take shots that transcend time and space and move smoothly. At this time, the digital Moving long take shot that continuously captures the space in all directions without an external screen induces a game experience. In addition, the camera that constantly accompanies the person enhances the sense of immersion in the game in a way similar to the point of view of the game. While various immersive device contents represented by VR, AR and XR are emerging, the advent of <1917> suggests significant implications for post-cinema in that it creates a game experience while maintaining the traditional screen environment and cinematic paradigm.

게임의 평가모델은 게임의 성공적 개발을 위하여 다양한 방향으로 연구되어 왔다. 특히 게임의 사전 평가는 게임의 성공을 견인하는 중요 요소로 인식되어 왔다. 다양한 장르의 게임을 평가하는 연구가 있어왔으나 4차 산업을 대두로 기술적 발달에 근거한 가상현실 게임과 증강 현실 게임 평가 항목은 연구 결과가 많지 않았다. 특히 증강 현실 게임에 중점하여 평가 항목을 연구한 결과는 전무한 상태이며 온라인 게임 등 다른 장르의 게임 평가항목을 이용하여 왔다. 특히 게임의 재미 요소를 근간으로 하는 평가 항목을 적용하기에는 어려움이 따르며 장르 및 플렛폼에 따라 평가 항목이 다양하여 증강 현실에 적합한 평가 항목을 개발하여 이를 적용하여 유용성을 확인한다.

Interest in Augmented Reality (AR) game $Pok{\acute{e}}mon$ GO is getting heightened. However, based on its characteristic, various direct and indirect problems are highlighted, thus increasing concerns. Although the game is not formally released domestically, there are limits in national game classification to apply on such outdoor Augmented Reality game. This paper will examine the problematic cases regarding Pokemon GO and analyze internal and external game classification system to discuss safe gaming measures for domestic users. In result of examining cases, need for adding 'physical danger' in current game classification system for user's safety was shown. As the government's game regulation is being eased, appearance of a variety of games using Augmented Reality technology in near future is predicable. Therefore it is important to prepare improvement of game classification system as a pre-safety measure, and it is expected to bring positive effect on game usage and industrial growth through safe game usage.

This study is intended to study the usage of augmented reality(AR) in the marketing field by classifying them into display and content types and analyzing the typical cases and characteristics. The market for AR has been on the increase and has been a big influence in the marketing field, resulting in the generalization of the term "AR marketing." By analyzing the marketing cases which use AR technology and organizing the frequency of use and characteristics, it is expected to contribute as a basic material for future studies on AR marketing. In this study, AR marketing cases are classified into different categories including display and contents. First, AR display category includes personal computers, mobile, public display, and projection display. AR contents category includes informative content, game contents, virtual experience, and visual effect. While investigating, it was found that the most used type of AR display was mobile, which has the advantage of not being limited by time and place and is also capable of one-on-one marketing with customers. The most used type of AR content was visual effect type, which evokes curiosity and is easily shared among people.

Recently it has been increasing interest of serious game which make broadened to wide area in game field. Among these, educatioonal serious game is not only satisfied with the purpose of fun and education but also has been looking ar new ways of teaching with distribution of digital textbook. It can lead to change the way we understand things using the revitalization on the basis of serious game competitions. The purpose of this study was to analysis of educational game and game competition and to develop the efficient management stragies.

In case of massive water leakage, it's crucial for field manager to quickly positioning the problematic valve and related ones. However, it's not easy for the system to find the corresponding valve and even if it's found, it can not respond quickly because it can't know the relevant information immediately. In this paper, we implement the system for identifying sluice valve positions using GPS and AR techniques. The proposed system is composed of hand held android device, remote database server and data acquisition device for DB creation. We utilize the android device's sensors including GPS, gyro, accelerometer, magnetic sensor. The system identifies the valve with matching between the position data from the remote database server, and current GPS locations of device. We use AR techniques to overlay the graphics pattern of valve positions and some additional informations on captured real scene. With this system, it will be fast and accurate for maintenance of sluice valve of municipal water system.

As augmented reality technology becomes more common and prevelant, marker-based AR contents are applied in various ways. However AR contents are still hardly utilized due to the low recognition rate of marker images. In order to increase the recognition rate of AR marker images, this paper experiment and analyzed how much the recognition rate of markers could be improved when image correction and design changes was applied. The experimental result shows that the image correction task could significantly improve the number of image characteristics and the recognition grade if the image was modified in a way its saturation value is increased. Moreover, the recognition rate was improved even more when regular pattern design was added to the original marker image. In conclusion, it was possible to make the marker well recognized through proper correction of the image and additional process of pattern design in the process of producing the marker image.

The needs for reusable 3D visualization tool has been being raised in various industries. Especially in the defense modeling and simulation (M&S) domain, there are abundant researches about reusable and interoperable visualization system, since it has a critical role to the efficient decision making by offering diverse validation and analyzing processes. To facilitate the effectiveness, states-of-the-arts M&S systems are applying VR (Virtual Reality) or AR (Augmented Reality) technologies. To reduce the work burden authors design a collaborative visualization environment based on a commercial game engine Unity3D. We define the requirements of the warfare simulation by analyzing pros and cons of existing tools and engines such as SIMDIS or Vega, and apply functionalities of the commercial game engine to satisfy the requirements. A prototype has been implemented as the collaborative visualization environment of iCAVE at KAIST, which is a facility for immersive virtual environment. The facility is intraoperative with smart devices.
