스마트한 환경에서 증강현실은 사용자와 매체간의 인터랙션을 통해서 다양한 경험의 확장을 제공한다. 위치 정보를 사용하는 방식, 마커를 사용하는 방식, 실시간 인터랙션을 활용한 마커리스 맵핑 방식등 실세계와 가상세계의 실시간으로 중간역할을 자리잡고 있다. 경험 확장의 한 요소이고, 현실세계의 정보를 증강하는 도구로써 활용되어지고 있다. 에듀테인먼트 교육적인 컨텐츠 관점에서 AR카드를 활용하였고, 마커리스방식으로 실시간 이미지 맵을 만들어 도시화 이미지 맵을 제작하였다. 3D환경에서의 입체영상을 활용한 오브젝트 제작과 증강현실을 접목한 인터랙션 교육컨텐츠 방식이다. 수동적인 관점에서 능동적이고 몰입도와 현실감 흥미를 높여주고 텐저블의 방식을 유도한다. AR카드에서 경험요소인 공간(활용), 시각(효과), 촉각(연동)을 활용하고 감각적 몰임감, 감각적 현실감, 인지적 조작성, 사회적 협력성, 인지적 융통성, 인지적 통찰성 등의 다양한 교육적 효과를 성취할수 있다. 스마트한 환경에서의 AR 마크리스 방식을 적용하여 AR카드를 활용한 이미지마크, 3D, AR 관점에서 분석하였다.

An alternative human interface enabling people with severe motor disabilities to control an assistive system is presented. Since this interface relies on the biosignals originating from the contraction of muscles on the face during particular movements, even individuals with a paralyzed limb can use it with ease. For real-world application, a dedicated hardware module employing a general-purpose digital signal processor was implemented and its validity tested on an electrically powered wheelchair. Furthermore, an additional attempt to reduce error rates to a minimum for stable operation was also made based on the entropy information inherent in the signals during the classification phase. In the experiments, most of the five participating subjects could control the target system at their own will, and thus it is found that the proposed interface can be considered a potential alternative for the interaction of the severely disabled with electronic systems.

For human beings, language is the most important means of communication. Bloom and Lahey see successful language development as an interaction between form, content, and use. Language knowledge is a social phenomenon produced in a socio-cultural environment through interaction. Teachers have traditionally concentrated on the structure of their student's writing rather than on the message. If writing is to be seen as an interactive social process between humans, it is the content which is responded to. Language acquisition could be a major problem for hearing-impaired children and their acquisition of written language is characteristically problematic. This study is to search the use of microcomputers in written conversational methods, which enable the hearing-impaired student to hear their conversations in a visual form and which usefully extend their written language learning opportunities.

This study analyzed the effect of the extracurricular activity management system on user satisfaction. For this purpose, the effects of content, navigation, screen frame, design, interaction, and error handling factors on user satisfaction were analyzed. A survey was conducted on 321 students of K University located in Chungcheongbuk-do, and the research results based on the survey contents are as follows. First, content, navigation, screen frame, interactivity, and error handling, which are major elements of the extracurricular activity management system, showed statistically significant results. Second, interactivity and error handling were found to have the greatest influence on the factors affecting user satisfaction of the extracurricular activity management system. In this study, it was found that the interaction of the whole system including contents is important for continuous improvement of the extracurricular activity management system, and that it has a positive effect on user satisfaction when prompt error handling is possible.

This paper proposes the system and method for converting the contents based on DLNA. Digital Media Controller (DMC) compares the media format of content which Digital Media Server (DMS) provides with the media format which Digital Media Renderer (DMR) supports and then, the content is converted dynamically. The interaction between home devices can make a conversion of contents dynamically and it enables people to enjoy the multimedia contents they like to watch whenever/wherever they want.

For the domestic digital contents, a proactive cooperation system or framework between the government, the businesses and research institutions, which would allow for free flow of interaction among these players, can play that role. We have proposed and realized the Dynamic Coordinating Framework(DCF) to bridge these gaps among the major players in the industry. The the Dynamic Coordinating Framework rests on the following major functions. The first major function of the DCF is to decipher any ambiguity that may be embedded in external inputs by stratified role and bias. The second function is to create cooperative groups that will deal with the ambiguities based on its consequent situation. The third is a feedback function that will draw out a new cooperative way by re-feeding the capacities and the conflicts that stem from the existing organizations and strategies into cooperation and adjustment process. Our DCF has compared and evaluated with England and Australia digital content industry models under AHP(Analytic Hierarchy Process) method. DCF has turned out to be well designed and have strong points based on OECD innovation and cooperation criteria.

E-books have been popular and common in everyday life during past a decade, and the market is expected to grow much more because of the popularity of tablet computing devices such as iPad. With the helps from the devices, people want to read or experience more interactive, fun, and informative e-book contents. In order to meet those needs, we introduce requirements of an e-book viewer system that supports user interaction, 3D modeling view, and augmented reality. We also introduce some design issues of the system and its concept proof prototype system. We determine to adopt HTML5 for e-book content format because it already supports content rendering, multimedia, and user interaction. Furthermore, it is easy to implement e-book viewer because there is already Webkit component for HTML5. We also discuss design issues for integrating an Augmented Reality viewer with Webkit-based e-book viewer. This paper will give e-book viewer developers and contents developers some guidelines for new e-book systems.

This thesis is a study of content development utilizing media outlets to date through digital humans. The trend of global content is that the video content industry, including the character business, is growing. Lil Michela, who was selected as one of the 25 most influential people on the Internet by Time magazine in 2018, Nasua, who appeared in a SK Telecom commercial, and Rosie, who appeared in a Shinhan Bank commercial, are representative. Digital humans, which are driving new content, are computer-generated human characters with various characteristics and are referred to as virtual humans, metahumans, and cyber humans. With the rise of the metaverse after COVID-19, digital humans are being utilized in various forms such as media and marketing as an element of visual content. In the form of media, we can see that the boundaries between the offline and digital worlds are converging, and in the form of marketing, we can see that digital humans connect consumers and products more naturally. In the form of interaction, it is possible to achieve two-way communication through various methods of operation, and through these factors, it is possible to go beyond behavioral communication in the form of memorialization to emotional communication through AI technology. What can be seen through these processes is that through the currently developing digital human production methods and AI functions, not only experts but also non-experts can create quality contents, and new directions of contents will appear, and contents that can provide immediate feedback by bringing consumers and creators closer together have been studied.

증강현실을 활용한 디지로그 북은 애플리케이션을 다운받은 후 모바일에 내장된 카메라를 Image Marker로 등록된 페이지에 비추면 증강현실이 구현되는 형태로서 콘텐츠 구현 방법에는 단편적 한계점을 나타내고 있다. 이에 본 연구에서는 증강현실 기술을 활용한 디지로그 북에 양방향 인터랙션이 가능한 팝업(Pop-up) 형태의 Multi-Tracking 방식을 제안하였다. 이를 통해 기존 책자형의 디지로그 북과 이번 연구에서 제안한 팝업(Pop-up)형태의 디지로그 북의 두 가지 프로토타입에 대한 증강현실 콘텐츠 구현에 따른 기술적 차별성에 대한 실험을 공인기관에 의뢰하여 검증하였고 시험성적서를 발급받았다. 연구에서 제안한 팝업(Pop-up)형태의 디지로그 북은 가상 이미지를 사용자의 행위(움직임)에 따른 인터랙션 콘텐츠 구현이 가능하여 책의 물리적인 변화자체가 가상콘텐츠에도 전달되는 양방향 인터랙티브 콘텐츠의 장점을 갖고 있으며, 이는 가상 이미지와 인쇄 그림책 간의 상호작용을 유도하고 학습자에게 흥미 유발 및 몰입감을 줄 수 있어 차별화된 디지로그 북의 인터랙션의 표현이 가능할 것으로 보여진다.

본 연구는 브랜드 웹툰의 디지털 스토리텔링 구성 요인(관련성, 진실성, 명확성)이 수용자와의 준사회적 상호작용과 브랜드 웹툰 콘텐츠에 대한 태도를 매개 변인으로 하여 구전 의도에 미치는 영향을 살펴보고자 수행되었다. 연구 결과, 브랜드 웹툰의 스토리와 브랜드 간의 관련성이 높고, 스토리가 진실하다고 지각할수록, 그리고 스토리의 명확성이 높을수록 수용자의 준사회적 상호작용 형성에 유의한 영향을 미치는 것으로 나타났다. 또한, 수용자와 브랜드 웹툰 스토리텔링 요인 간의 준사회적 상호작용은 브랜드 웹툰에 대한 태도에 의해 매개되어 구전 의도에 긍정적인 영향을 주는 것으로 확인되었다. 본 연구의 결과는 스토리텔링 측면에서 브랜드 웹툰이 강화해야만 하는 구성 요인을 규명함과 동시에, 수용자와의 준사회적 상호작용을 증가시킴으로써 브랜드 웹툰의 구전 의도를 높일 수 있다는 실무적 시사점을 제공하고 있다.
