In this paper, we propose a method of constructing AR game spaces through cuboid detection in indoor environment. Conventional spatial recognition methods can detect planes only in limited spaces that can be well observed. They are also vulnerable in density and noise. The proposed method overcomes the limitations of the conventional method by constructing AR game spaces by a method of detecting OBBs from spherical videos. Experimental results showed that the proposed method is faster than the conventional method and it is also robust against environmental constraints such as changes in density and noisy.

This paper presents a design and implementation of U-Seum(Ubiquitous Museum) system based on the LBS(Location Based Service) and mobile augmented reality technique. The mobile services under the smart space of the ubiquitous environments have been expanded in the various fields. In this study, we introduce U-Seum which supports tourists in the museum. U-Seum is developed by use of the position tracking technique based on Wi-Fi and mobile augmented reality. The GPS which is widely used in the position tracking has a difficulty to be utilized in the inside of the building because it requires the Line-of-Sight between a sender and a receiver. Therefore, in this paper, we develop a realtime tour-supported service through experience and evaluate the performance of the system in the world famous UNESCO's Hwa-Seong Museum by measuring the distance from the Wi-Fi signal which is suitable to track the position interior of the museum. U-Seum provides various push services such as mobile augmented reality service for explanation of the artifacts of the museum, game services and the statistics information of the tourist when the tourist approach a specific AP. U-Seum is developed in the Haw-Seong Museum by the support of the Swon Haw-Seong Cultural Foundation. With a field test, we prove that the excellence and expandability of the system.

In recent years, as the importance of history has increased through various social issues, media, and journalists in Korea, it has led to the value of 'right history' and 'teaching history that is right. History of a country is also a core asset in a country 's cultural contents industry, and historical relics are important to prove its value. As the interest in the historical and cultural heritage has increased, researches to develop it as cultural contents by restoring it as information and communication technology such as multimedia and virtual reality are active. In this paper, we propose convergence device and contents that can provide rich experience and various learning opportunities in artifact experience through restoration of artifacts using augmented reality. The study on the application effect of educational game contents which can add fun can be continued.

A mobile phone is becoming no longer a voice communication tool due to smartphones and mobile internet. Also, it now becomes a total entertainment device on which we can play game and get services by variety applications through the Web. As smartphones are getting more popular, their usages are also increased, which makes the interest of advertising industry in mobile advertisement increased but it is bound to be limited by the size of the screen. In this paper, we suggest an augmented reality logo system based on Android platform to maximize the effect of logo advertisement. After developing software and mounting it on a real smartphone, its performances are analyzed in various ways. The results show the possibility of its application to real world but it's not enough to provide real time service because of the low performance of hardware.

경제수준의 향상과 삶의 질의 향상으로 인하여 일반인들의 건강 및 운동에 대한 관심이 증대되었다. 이런 사회적 기대에 부응하여 바쁜 현대인들을 위한 게임 기반 및 스마트폰 기반의 헬스케어 시스템이 등장하고 있다. 최근에는 가상현실을 통한 현실세계와 유산한 운동효과를 추구하는 형태로 발전하고 있다. 따라서 본 연구는 가상세계의 현실과 같은 몰입감에 주목하고, 아이큐브(I-cube)를 활용하여 가상현실을 구축한 다음 가상의 트레이너를 통해서 원하는 운동효과를 제공하는데 목적이 있다. 운동 및 자극 부위, 지도 효율성의 정보 등을 제공하여, 운동효과와 정보를 한눈에 봄과 동시에 운동에 대한 올바른 자세를 가상현실을 이용해 직접적으로 배울 수 있도록 하였다.

To enable effective notification and promotion of the food poisoning prevention, Ministry of Food and Drug Safety (MFDS) developed a mobile augmented reality (AR) game called 'Sik-Jung-Dok-Jop GO', and demonstrated the game at 11 events including Food Safety Day. At the events, we have conducted a field survey of people who have played the game, and evaluated the awareness change of the food poisoning before and after the game. The level of the respondents' awareness about the 3 methods of the food poisoning prevention has been increased by 53 percent after playing the game, the level of awareness about individual food poisoning micro-organism has been improved by 2.1 times. According to the survey, 95% at the respondents answered that the game helped them understand the food poisoning more, and 90% of the respondents said that they enjoyed the game. In conclusion, we believe that 'Sik-Jung-Dok-Jop GO' will be able to create various educative effects on prevention of food poisoning including causative foods, main symptoms, and other related knowledge when the game is widely applied to students in kindergartens, elementary, middle, and high schools.

스마트 폰의 등장과 모바일 인터넷을 제공함에 따라 휴대폰은 음성통신 수단이 아닌 웹을 통하여 서비스를 제공받는 도구 또는 각종 게임 및 응용 어플리케이션을 제공하는 놀이수단으로도 발전하였고, 이로인하여 사용량도 증가하였다. 사용량의 급증으로 인하여 모바일 광고에 대한 업계의 관심도 증가 하였지만, 한정적인 출력화면에 의하여 제한적일 수밖에 없다. 이를 보완하기 위해, 본 논문에서는 기업의 로고 광고의 효과를 극대화 할 수 있는 안드로이드 기반 로고를 인식하는 증강현실 시스템을 제안 하였고, 이를 구현 하여 실 제폰에 탑재한 후 다양한 성능 분석을 하였다. 실험결과, 그 가능성은 확인하였지만 현하드웨어 성능으로는 실시간으로 지원하기에는 역부족임을 알 수 있었다.

With the rapid development of scientific technologies and the appearance of new industrial areas, the 4th industrial revolution is rapidly progressed while new values are created and realized by the conversion between industries. The researcher wrote the main questions through the preceding research on domestic and overseas major new technology convergence products and services. The researcher planned the in-depth interview, which is one of the qualitative research methodologies, and conducted the Kano method questionnaire that can embody multidimensional and strategic judgment rather than grasp fragmentary preference trends. According to the results, In addition to strengthening the technical capabilities of the VR/AR game industry, policy needs to raise professional manpower have been raised. Practical workforce development through close collaboration between industry and educational institutions, and continuous supply of human resources through retraining of existing game contents personnel. It gave direction to the creation of new jobs in the VR/AR game industry.

It has been a year since the $Pok{\acute{e}}monGo$ has been released. Over the past year, the $Pok{\acute{e}}monGo$ have become a social phenomenon. This study analyzes the dual characteristics play of the original $Pok{\acute{e}}mon$ game. The Pocket Monster game, which has both casual and hardcore capabilities, has a broader player base and enjoys popularity for 20 years, satisfying the requirement of easy and convenient access, which is an advantage of casual games. In addition, the rating battle system of $Pok{\acute{e}}mon$ game turns casual play into hardcore play. In this paper, we analyze the dual play characteristics of longevity games such as Pocket Monsters, and propose strategies and directions for game development that can survive long term in the competitive game market.

Mobile based location-based service can normally be classified into four categories according to their dimensions of their screen layout: map-based, bird-eye view based, photo-based, and video-based. Specifically, video-based layout system combining AR technology has a appealing factor to users through the reality-based presence but normally requires sophisticated real-time image matching algorithms to represent the system. This paper provides a new location-based service by introducing mirror world to resolve the problem and implements its prototype. The proposed service does not need such algorithm and will effectively be useful for users to get the reality of the presence for any locations which is regardless of a user's real location.
