In this paper, we have proposed a new geometric solution of inverse kinematics of high instinct, while traditional solutions of inverse kinematics requires high level of mathematical knowledge. It was possible to use the inverse kinematics without mathematical knowledge because 3D vectors of directions of folded bones could be calculated by our method in the inverse kinematic model of two bones. The proposed method can be utilized easily by graphic designers who have little knowledge of mathematics of inverse kinematics

The next generation Web 2.0 users are requiring a screen that satisfies visual and emotional factors regarding UI and the possibility of constant recognition about various information. To actively deal with these kinds of user demands, dual cooperation between the developer and designer is becoming more urgently needed. For this, Microsoft released Silverlight, a tool for when making a web presentation that enables persons to create a visually stunning webpage using diverse platforms and function. We applied clarity and animation to existing windows concepts, using Silverlight with which designers and developers can work together and is accessable to many development tools, and provided 3D effects to implement a Warehouse Management System.

While many games have been published that are used with input-devices such as a mouse and keyboard, the number of games that can recognize the behavior of a human utilizing devices such as Kinect and Wii has increased. In this paper, we present the development of a baseball game that utilizes a Leap Motion Controller. A Leap Motion Controller recognizes accurately the movement of a user's fingers. Our implemented game consists of characters, a background and animation. It is a moving animated game in which the users play a game in point of view of a third person. The major feature of our game is that the game players can enjoy the game using a Leap Motion Controller.

Hologram can be categorized into analog and digital hologram but there's a clear limitation in expensive equipment and content realization for ordinary people to realize. In addition, it's required to conduct study on hologram contents with interaction added, escaping out of exiting stable format like endlessly repetitive contents or passive view through specific video. Therefore, this article aims to suggest fusion image system, especially focusing on floating hologram among similar holograms. Eight elements of hologram interaction are as follows: height of camera in a three-dimensional space, interval between 3D model, overlapped model, scale, animation, position, color and 3D model change. For the floating hologram, the audience can control by themselves in real time, the popular, active hologram contents-making methodology is suggested by making the best use of fusion image system and making floating hologram easily without using expensive hologram equipment. The image system developed in actual exhibition and feedback should be complemented to develop better hologram image system.

모션 캡쳐 결과 데이터와 연속 이미지로부터 구현하고자 하는 가장 큰 목적은 바로 이미 적용된 데이터가 있다면 그 데이터를 다른 모든 신체 동작에 적용하는 것이다. 본 연구는 신체 동작을 응용하여 추적된 자료를 토대로 인간의 자연스러운 움직임을 구현할 수 있도록 인체 동작의 움직임에 대한 데이터 제어 방법과 영상분석을 통하여 그에 대응하는 다른 동작을 생성할 수 있는 재사용 방법과 시스템을 개발하는 것이 목적이다. 이와 같은 시스템을 달성하기 위해 신체 동작의 제어를 위해서는 외국의 선행 연구를 도입하여, 신체 동작의 움직임에 대한 제스춰 성분 요소와 그것의 조합을 표상할 수 있는 제스춰를 연결하는 모형들에 근거하여 입력 영사에서 얻은 제스춰를 다른 d사한 동작에 사용하기 위한 합성하는 기술의 개발이 필요하다. 향후의 이러한 연구를 통해 획득한 인체 동작에 관한 것을 데이터베이스화하여 이것을 활용하고 또한 동작제어기술과 합성을 통하여 가상공간에서 사람의 동작행위를 대신할 수 있는 수준으로 확장할 수 있다.

To create a more realistic soccer game derived from TV images, we are developing an image synthesis system that generates 3D image sequence from TV images. We propose the method for the team and the pose recognition of players in TV images. The representation includes camera calibration method, team recognition method and pose recognition method. To find the location of a player on the field, a field model is constructed and a player's field position is transformed by 4-feature points. To recognize the team information of players, we compute RGB mean values and standard deviations of a player in TV images. Finally, to recognize pose of a player, this system computes the velocity and the ratio of player(height/width). Experimental results are included to evaluate the performance of the team and the pose recognition.

In early stages of film or animation production, storyboard is used to visually describe the outline of a story. Drawings or photographs, as well as the texts, are employed for character / item placements and camera pose. However, commercially available storyboard tools are mainly drawing and editing tools, not providing functionality for item placement and camera control. In this paper, an Augmented Reality based storyboard tool is presented, which provides an intuitive and easy-to-use interface for storyboard development. Using the presented tool, non-expert users may compose 30 scenes in his or her real environments through tangible building blocks which are used to fetch corresponding 3D models and their pose.

Ubiquitous computing is a vision of our future computing lifestyle in which computer systems seamlessly integrate into our everyday lives, providing services and information in anywhere and anytime fashion. Augmented reality (AR) can naturally complement ubiquitous computing by providing an intuitive and collaborative visualization and simulation interface to a three-dimensional information space embedded within physical reality. This paper presents a service framework and its applications for providing context-aware u-car maintenance services using augmented reality, which can support a rich set of ubiquitous services and collaboration. It realizes bi-augmentation between physical and virtual spaces using augmented reality. It also offers a context processing module to acquire, interpret and disseminate context information. In particular, the context processing module considers user's preferences and security profile for providing private and customer-oriented services. The prototype system has been implemented to support 3D animation, TTS (Text-to-Speech), augmented manual, annotation, and pre- and post-augmentation services in ubiquitous car service environments.

애니메이션은 세계 어느 나라이든지 해외 판매를 인식하고 있으므로 국제적 소재와 내용이 중요하다. 이러한 애니메이션 필요성에 따라서 국내에서도 이와 관련된 학과들이 수없이 말이 생겨나고 있으나 애니메이션 제작에 대한 디지털 컨텐츠가 매우 부족해서 수작업이나 과거 만화 애니메이션 형태에 국한하고 있는 곳이 대부분이다. 본 논문은 이러한 점에 착안해서 애니메이션 제작과 실습 모델을 개발했으며, 그 내용은 다음과 같다. "세계의 애니메이션 동향", "애니메이션 제작 방식", "카메라웍크", "세계의 애니메이션 작품소개", "애니메이션 제작 및 실습"의 주 메뉴와 7가지의 보조버튼 "한국의 3D 애니메이션", "북한 애니메이션 실상", "특집 포켓 몬스터", "애니메이션을 위한 포토샵", "애니메이션을 위한 플래쉬", "애니메이션을 위한 라이브 모션", "애니메이션과 디자인" 등이다.

Flooding is an inevitable problem for many cities. The study has depended on a combined approach of physically based modeling and GIS. The stream network is structured by MIKE11 for basis of a network and extended by MIKE21 to make like 2D analysis. This method is called alternative 2D analysis. In this study, one of area in Korea is used to analyze overflow of stream. Flood risk of the area looks like not so big because an elevation of this area is very high and slope is steep, but it is very dangerous area due to the typhoons. The tools to make flood risk map are MIKE11 and MIKE21 include GIS program. And map is expressed 3-D animation with MIKE Animator. As a result of this work, the flood risk map is made. And everyone who is not an expert can check dangerous area for flooding. At present, the method which is viable and easily confirmable must be promote because one of matters of common interest, which is of the general public, is the flood disaster.
