The purpose of this study is to explore the educational potential of digital story telling in Second Life with three-dimensional virtual reality. Virtual reality such a Second Life can provide to learner chance with the rich learning environment through fidelity. In this study, we have been measured the fun and comprehension among three groups on digital storytelling types. Through the result of experimental, comprehension was no significant but fun was different among three groups on storytelling. we have the result that experiential activity in virtual reality that provide to get the identification as a main character, good environment is influenced the fun to learner via engagement facilitation.

In this paper, we propose an intelligent vocabulary recommendation agent that automatically provides vocabulary corresponding to game-based learners' needs and requirements in the mobile education augmented reality game environment. The proposed agent reflects the characteristics of mobile technology and augmented reality technology as much as possible. In addition, this agent includes a vocabulary reasoning module, a single game vocabulary recommendation module, a battle game vocabulary recommendation module, a learning vocabulary list Module, and a thesaurus module. As a result, game-based learners' are generally satisfied. The precision of context vocabulary reasoning and thesaurus is 4.01 and 4.11, respectively, which shows that vocabulary related to situation of game-based learner is extracted. However, In the case of satisfaction, battle game vocabulary(3.86) is relatively low compared to single game vocabulary(3.94) because it recommends vocabulary that can be used jointly among recommendation vocabulary of individual learners.

We In this study, We tested for artificial intelligence-based virtual space story books were planned. The proposed virtual space concept, a story book with the characteristics of Augmented Virtuality, was implemented Several steps are needed to proceed with the virtual space storybook's story. First, a user brings a real object in to virtual space and recognizes the real object with an artificial intelligence-based object-recognition software. Second, when object recognition progresses, the virtual 3D model is augmented in the virtual space, which is then inserted into the virtual space and rendered. Finally, software projected a virtual space storybook on the desk in which users can touch and select real-objects. This virtual space storybook was implemented using the new story-making technology by applying the virtual space concept. the Augmented Virtuality concept is to augment real objects based on virtual space. To confirm this we tested a user test using the virtual space storybook. the user seemed as if can the distinction between real objects and virtual images. Also very well and that understood the process of putting the real objects in virtual space.

Prior studies have reported equivocal patterns of the results about the relationships between family involvement and firm performance, particularly financial performance. In line with this research trend, this study focuses on non-financial performance that agency costs may marginally influence. tries to identify the relationship between nepotism and the three types of innovation performance, namely corporate entrepreneurship, radical innovation performance, and incremental innovation performance. The results has shown that family involvement is positively correlated with the three types of innovation performance.

엔지니어링 분석을 위한 가상현실 응용 분야에서는 대규모 또는 복잡한 공학적 데이터를 효율적으로 분석하고 의미 있는 정보를 추출하기 위해 대형 스크린 등의 몰입형 가시화 인터페이스가 주로 사용된다. 이와 더불어 가시화 결과에 대한 사용자의 분석 조작을 구현할 수 있는 휴먼 인터페이스 기술이 필요한데, 기존의 휴먼 인터페이스 기술은 조이스틱과 같은 단독 활용형 디바이스를 통해 주로 운영자 위주의 단방향 검토가 가능하지만, 최근 착용형 및 비착용형 모션인식 기술의 발전으로 인해 가상현실 참여자간의 양방향 상호작용 인터페이스 개발이 가능할 거승로 기대된다. 본 연구에서는 신체의 자연스러운 움직임으로 가상현실을 조작할 수 있는 휴먼 이터페이스 기술에 대한 분석과 기초 연구를 소개한다.

우리나라는 2000년에 고령화 사회에 공식적으로 진입하였으며 고령화는 더욱 가속화될 전망이다. 노인의 경우 신체적, 인지 및 심리적, 사회적 기능이 저하되어 올바른 사회활동을 하기가 어려울 뿐만 아니라 특성상 새로운 활동을 기피하고 쉽게 지루해 하며 소극적인 성격으로 인해 운동참여 유도가 어렵다. 노인의 건강 증진을 위해 운동 실천률을 높이는 것이 필요하며 쉽게 접근할 수 있고 상해의 위험성이 적은 환경이 제공되어야 한다. 가상현실을 기반으로 한 스포메디 융복합 기술은 스포츠를 가상현실로 구현하여 의료적 효과를 극대화 할 수 있는 기술로써 사용자의 흥미를 유발하고 운동 및 치료의 효과를 동시에 가능하게 하는 기술이다. 본 논문에서는 노인의 특징을 분석하여 가상현실 스포메디 융복합 기술이 갖춰야할 특성에 대해 제시하고, 관련 개발 기술의 연구 및 개발 동향과 스포메디 관련 시장 동향 및 정부 정책 방향에 대해서 분석하였다.

스마트폰의 폭 넓은 보급으로 인해 스마트폰 시장은 급격한 성장을 이루었고, 모바일 환경의 발전은 다양한 형태의 애플리케이션의 개발과 모바일 게임 시장의 성장으로 이어졌다. 모바일 게임에서 사용자간 상호작용은 중요한 요소가 되었다. 하지만 대부분의 모바일 게임들은 소셜네트워크상의 초대와 아이템의 제공, 스코어 비교 등에 그치는 등 제한된 영역에서의 상호작용에 그치는 경향이 있다. 이에 본 논문에서는 메시지 서버를 활용하여 다수의 모바일 디바이스를 유기적으로 연계, 모바일 디바이스의 화면이나 기능을 확장하고 게임세계와 현실세계의 접목을 통한 새로운 형태의 게임 가능성에 대해 연구하였다.

Smartphones provide users with environment for communication and sharing information and at the same time play an important role of mobile technology and mobile art development. Smartphone technology-related researches are being accelerated especially with the advent of mobile Augmented Reality(AR) age, but the studies on user participation that is essential for AR content industry were insufficient. In that regard, the assistance from mobile art area that has already developed these characteristics is essential. Thus, this article is to classify mobile art that has not been studied a lot domestically into feature phone usage and smartphone usage and to analyze each example case with the three most used methods. The usage of feature phones which use the sound and images of mobile devices can be divided into three: installation and performing methods, single channel video art method and five senses communication method. On the other hand, the usage of smartphones that use sensors, cameras, GPS and AR can be divided into location-based AR, marker-based AR and markerless AR. Also, as a result of examining mobile AR content utilization technology by industries, combined methods are utilized; tourism and game-related industries use location-based AR, education and medicine-related industries use marker-based AR, and shopping-related industries use markerless AR. The development of AR content industry is expected to be accelerated with mobile art that makes use of combined technology method and constant communication method through active participation of users. The future development direction of mobile AR industry is predicted to have minimized HMD, integration of hologram technology and artificial intelligence and make the most of big data and social network so that we could overcome the technological limitation of AR.

In this study, we compared discourse by environments for using tools in terms of participation types, discourse types, and knowledge building processes. 24 first-year high school students were divided into six groups. They were assigned to the sharing tools environment, which used one marker and one smart device, or the individual tools environment, which used markers and smart devices individually. Students participated in small group learning using AR application based on the concept of chemical bonding. All classes were video- and audio-taped. Semi-structured interviews were conducted with six students who voluntarily agreed. The results of the study revealed that the sharing tools environment had a high proportion of one-student dominating type, while the individual tools environment had a high proportion of partly participating type and most students participating type. In the individual tools environment, the ratio of knowledge sharing and knowledge construction discourse was similar compared to the tool sharing environment, and the sub-discourse types were also diverse. In the sharing tools environment, only some students had a meaningful knowledge building process. On the other hand, in the individual tools environment, most of the group members constructed knowledge about the target concept, and had a meaningful knowledge building process. In addition, the misconceptions that appeared to some group members were corrected through small group discussions.

This paper summarizes the characters of virtual reality contents and its design problems, and suggests user centered approach in design methodology of VR contents. Based on case study of former VR contents design project, I developed a new VR contents design process in experience design perspective. This design process was applied on Tangible Space Initiative project of KIST, which showed positive roles of this design process as a dear communication media between project players, and an active generator of user-centered interaction design.
