Recently, due to improvement of computer performance and development of information devices, technology of mobile augmented reality is proliferating rapidly. However, because most of contents are passive or limitary, user can not feel interest and immersion. This paper designs interaction user interface system of 2 dimensional drawing based on mobile augmented reality to make bi-directional communication between the real world and the virtual world possible by using the vision based augmented reality and the database system.

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.

가상세계는 현실세계를 반영하여 만든 가상의 공간이다. 이러한 공간간에서 여러 사용자들은 서로의 의견을 교환하며 여러 가지 작업을 한다. 이러한 작업들을 이벤트라고 부르며 기존의 다중 참여자를 지원하는 브라우저들은 객체에 대한 이벤트가 발생했을 대 모든 사용자에게 똑같은 화면을 보여줌으로써 사용자의 소극적인 의사표현만을 제공하였다. 그러나 사용자에 따라 이벤트가 발생했을 때 보고싶은 객체의 위치나 크기 등이 다를 수 있고 때로는 자신의 작업 중에는 이벤트의 발생을 알고 싶지 않은 경우도 있다. 따라서 본 논문에서는 이러한 사용자들의 욕구를 만족시키도록 객체의 이벤트가 발생하였을 때 화면을 표현하는 여러 가지 방법(Presentation Level Sharing, View Level Sharing, Object Level Sharing)을 제시하고 사용자로 하여금 선택하여 볼 수 있도록 제안한다. 또한 이벤트 발생시 표현 방법에 따라 객체를 포함한 영역의 크기도 함께 결정 할 수 있도록 한다.

We can travel every imaginary world and do every impossible thing via 3D character. People interest in 3D character animation for modeling like real world due to the increase of 3D game and imaginary Virtual Reality on the internet. In this paper, new framework for present of 3D character of high quality is applied. I represent 3-dimensional Humanoid modeling and animation technology and show the adequacy via simulation for various and natural representation certificate using VRML as a Web3D information type and XML.

This paper proposes a new metadata schema for effective mobile service of augmented reality technology, which is used in the convergence of media into a frame among the real world image and objects of virtual world. The proposed metadata schema is extended from JPSearch Core Metadata Schema (ISO/IEC 24800-2 International Standard) with analysis of the functionalities under industrial requirements, and enables to provide an effective application in the actual services. In addition, the proposed schema is available to organize the exchange of information between heterogeneous systems. With development of the prototype system, the proposed metadata schema is going to be submitted and verified under ISO/IEC JTC1 SC29 WG1 JPEG AR standard project.

In this paper, we propose mobile Augmented Reality(AR) for smart learning system which is advanced e-learning. AR is technology that seamlessly overlays computer graphics on the real world. AR has become widely available because of mobile AR. Mobile AR is possible to get information from real world anytime, anywhere. Nowadays, there are various areas using AR such as entertainment, marketing, location-based AR. One of the most promising areas is education. AR in education shows lifelike images to users for realism. It's a good way for improving concentration and attention. We utilize only a camera for image-based AR without other sensor.

In this paper, we review relevant technologies of MR (Mixed Reality) and show important components of perspective that can overcome technical limitations of the current MR. An MR technology combines real and virtual objects in a real environment, and runs interactive in real time, and is regarded as an emerging technology in a large part of the future of IT (Information Technology). We've grouped the major obstacles limiting the wider use of MR technologies into three themes: technological limitations (i,e., tracking, rendering, authoring, and registration), user interface limitations(i.e. UI metaphor for MR interaction), and social acceptance Issues.

세상을 담은 책 한권과 개인의 관계는 곧 열린 세계에 대한 열망과 일치한다. 화가는 새로운 세계를 그렇게 인식한다. 그림 안에서 묘사되는 책은 현실에서 책이 담고 있는 것만큼 세상을 담고 있다.

Recently, Augmented Reality(AR) technologies have been emerged, which shows the types of digital contents integrating real and virtual worlds. To maximize the effect of AR technology, tangible user interface, which enables users to interact with the contents in the same way in which they manipulate objects in real world, is applied. In particular, we expect that the technologies are able to enhance learners' interests and degree of immersion, and produce new learning contents in order to maximize the effect of learning. In this paper, we propose a learning system for scientific experiments with multi-touch screen and tangible user interface. The system consists of an experiment table equipped with a large multi-touch screen and a realistic learning device that can detect the user's simple gestures. In real world, some scientific experiments involve high cost, long time or dangerous objects, but this system will overcome such hindrance and provide learners with a variety of experiment experience in realistic ways.

This article sees the core characteristics of the elderly movies, which have become active in the 2000s, as the structure of fantastic dream. And I analyze the aspect and significance of the structure of fantastic dream .of 'reality-dream-reality', which is centered on . The structure of fantastic dream. is a traditional form handed down from the Silla era, and it is well-known in "Gumoshinwha" and "Guunmong". In , the aspect of the structure of fantastic dream is summarized as 1)the duality of person and space, 2)the boundary between reality and unrealism. In this film, heroine is suffering from a disagreement with daughter-in-law, hospitalized in a nursing home. After heroine passed the world of dreams, becomes a new person. expresses the process of solving the conflict of the characters, realizing the hope, and the process of mental rebirth through a structure of fantastic dream. The elderly movies accept the universality of the structure of fantastic dream and the special characteristics of an aging society.
