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.

One of the most important technologies today is augmented reality technology, it allows users to experience the real world using virtual objects that are combined with the real world. This technology is interesting and has become applied in many sectors such as the shopping and medicine, also it has been included in the sector of education. In the field of education, AR technology has become widely used due to its effectiveness. It has many benefits, such as arousing students' interest in learning imaginative concepts that are difficult to understand. On the other hand, studies have proven that collaborative between students increases learning opportunities by exchanging information, and this is known as Collaborative Learning. The use of multimodal creates a distinctive and interesting experience, especially for students, as it increases the interaction of users with the technologies. The research aims at developing collaborative framework for developing achievement of 6th graders through designing a framework that integrated a collaborative framework with a multimodal input "hand-gesture and touch", considering the development of an effective, fun and easy to use framework with a multimodal interaction in AR technology that was applied to reformulate the genetics and traits lesson from the science textbook for the 6th grade, the first semester, the second lesson, in an interactive manner by creating a video based on the science teachers' consultations and a puzzle game in which the game images were inserted. As well, the framework adopted the cooperative between students to solve the questions. The finding showed a significant difference between post-test and pre-test of the experimental group on the mean scores of the science course at the level of remembering, understanding, and applying. Which indicates the success of the framework, in addition to the fact that 43 students preferred to use the framework over traditional education.

The purpose of this study was to investigate the existing augmented reality (AR) contents in education and to develop digital AR contents to promote the learning outcomes in nursing skills education. AR contents has been widely used in education such as children's books, coloring, or exhibition experiences, but rarely developed in nursing education. We wanted to develop AR contents on nursing skills which required memorization of complex contents. In order to improve nursing students' memorization skills, we developed AR techniques holding and executing cameras along with game elements of time and points. In order to give the effect of placing objects in front of the user's eyes, an augmented reality camera was applied, and a total of 40 levels were created to produce the sequence of nursing techniques. This study showed that learning contents in the medical field requiring expertise could be implemented as AR contents. The content developed in this study will be used as a learning aid for nursing students.

TV에서 OTT로 시청 수단이 변화하면서 스포츠 중계를 보는 젊은 층 시청자들이 줄어들고 있다. 또한 경기장으로 스포츠를 보러 오는 팬들도 점점 감소하는 추세이다. 이에 따라 스포츠 관계자들은 고정 팬 층의 흥미 증진과 신규 팬 층의 유입을 위해 스포츠 관전에 AR(증강 현실) 기술을 도입하고 있다. 모바일 활용과 직관에도 적용 가능한 AR에 대한 업계의 반응은 상대적으로 긍정적이다. 본 논문에서는 AR 스포츠 관전의 사례를 스포츠 중계와 경기장 관전으로 분류해 조사하고 향후 전망에 대해 알아본다. 그리고 AR 스포츠 관전의 활성화에 대한 방안을 제시한다.

Motion capture system that is used in movies and games today requires large equipments and expensive that it is still not common as a reasonable family game. Therefore, this research project focused on solving these problems mentioned above and move on to develop a new type of approach and by using reasonable family use USB camera and augmented reality to develop a bodily sensation motion capture system which can be used in making a video game. In order to develop this, I used a pair of Marker which can be placed on both hands and one USB camera and the image that was extracted in real time goes through the AR toolkit and ed the 3D coordinates of data and developed a motion capture system.

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.

With the aid of the increasing interests of Context-aware Augmented Reality Agent (AR Agent), various researches of AR Agent have been performed to explore the possibility of the agent as novel interface and the entity responding autonomously by user's input. However, in previous works, AR Agents are lack of specific method for using various contextual information. To revolve around those problems, we propose the Behavior Generation System for Context-aware AR Agent using layered architecture. Based on Belief-Desire-Intention (BDI) model and Hierarchical Task Network (HTN) searching, the sequence of agent behavior has been selected in behavior planning layer. Then, the agent evaluates appropriateness of behaviors using previous behavior and the type of input before activation. This behavior generation system can be applied for edutainment, game, and assistant agent, which need intuitive and effective behaviors to convey information. Through this research, we expect that the Context-aware AR Agent could support for not only information delivery, but also the capability of effective communication for user.

This paper is a study on the production of mixedeality contents by realizing AR coloring technology, virtual environment, and VR devices by realizing the interaction in virtual environment. In this study, we designed and produced the content from a fairy tale called 'Cinderella' to produce and demonstrate real mixed reality contents. 'Cinderella' shows 3D modeling in the virtual space using the Oculus Rift, and the modeled shoes can be lifted using Leap-Motion. It is a virtual augmented interaction content for exhibition and experience that can move a specific range from the foot on the treadmill. In this paper, we try to share the experience of creating new mixed reality game contents, which is a mixture of augmented reality and virtual reality technology, and continuation of universal use of this field.
