This paper proposes a robot motion authoring using finger-robot interaction. The proposed method is a user friendly method that easily authors (creates and controls) robot motion according to the number of fingers. The effectiveness of the proposed motion authoring method was verified based on motion authoring simulation of an industrial robot.

This paper proposes a multi-modal complex motion authoring tool for creating robot contents. The proposed tool is user-friendly and allows general users without much knowledge about robots, including children, women and the elderly, to easily edit and modify robot contents. Furthermore, the tool uses multi-modal data including graphic motion, voice and music to simulate user-created robot contents in the 3D virtual environment. This allows the user to not only view the authoring process in real time but also transmit the final authored contents to control the robot. The validity of the proposed tool was examined based on simulations using the authored multi-modal complex motion robot contents as well as experiments of actual robot motions.

The work of creating character motion needs the higher professional technology and sense and the creating work of realistic and natural motion possess the most part of production term. In this paper we introduce the easy and convenient 3D animation authoring tool which makes the motion based on whole-body inverse kinematics and motion editing function. The proposed 3D animation authoring tool uses the forward kinematics using quaternion and whole-body inverse kinematics to determine the rotation and displacement of skeleton. Also, it provides the motion editing function using multi-level B-spline with quasi-interpolant. By using the proposed tool, we can make 3D animation easily and conveniently.

Interactive media is a method of communication in which the output from the media comes from the input of the users. The interactive media lets the user go back with the media. Interactive media works with the user's participation. The media still has the same purpose but the user's input adds the interaction and brings interesting features to the system for a better enjoyment. We need a digital content using a dynamic motion and gesture of the mobile device. We made an authoring tool for content producers to easily create interactive content. We have tried to take advantage of the interaction by using a touch screen and a gravity sensor of the mobile device. This interaction may lead to allow the user to participate in the content, it can be used as a key device to assist in engagement. Furthermore, our authoring tool can be applied to various fields of publishing content.

Elderly people living alone need smart care for independent living. Recent advances in artificial intelligence have allowed for easier interaction by a computer-controlled virtual human. This technology can realize services such as medicine intake guide for the elderly living alone. In this paper, we suggest an intelligent virtual human and present our virtual human toolkit for controlling virtual humans for a senior citizen living alone. To make the virtual human motion, we suggest our authoring toolkit to map gestures, emotions, voices of virtual humans. The toolkit configured to create virtual human interactions allows the response of a suitable virtual human with facial expressions, gestures, and voice.

In this paper we analyze whether we can use the mobile phone having been highly distributed into young generation as a device for the u-learning in Korean public education. For this purpose we deal with the technical maturity in three axes. Firstly, we examine the authoring nature of mobile internet-based contents such as both text and motion picture for the contents developers in the public education. As a research result the authoring of text has almost no difficulty, but that of the motion picture shows some problems. Secondly, we deal with whether u-learners can easily get and use u-contents on both mobile phone and PC respectively. After analysing this factor, we found that the downloading of motion picture contents into mobile phone is very limited. Therfore we talk about the usability and problem of various PC Sync tools and propose their standardization. Finally, the needs of the introduction of the ubiquitous SCORM which could enable to reuse u-contents among different Korean telco’s mobile phones are discussed. Here we describe some functionality of both ubiquitous SCORM and u-LMS. Our study looks like almost the first work examining the technological maturity for the introduction of u-learning with mobile phone in Korean public education and it could be used as a reference for the study of any other wireless telecommunication-based u-learning other than mobile telecommunication.

증강현실에서 움직이는 가상 모델을 증강물로 활용하려면 대개 별도의 모델링이나 애니메이션 도구 사용이 필요하며 이는 매우 전문적이고 복잡한 작업이다. 본 논문에서는 그러한 과정 없이 동적 가상 객체를 증강 환경에 삽입할 수 있는 방법으로 비디오 객체 기반 저작 방법을 제시한다. 그랩컷과 그로컷을 통합 적용하여 대상물의 초기 영역을 분리한 후, 스냅컷을 이용해 프레임간 경계선 변화를 자동 추적하여 동작이 담긴 연속 프레임을 실사 비디오에 증강하는 방식이다. 실험결과로, 몇 단계의 메뉴 선택과 경계선 오류 정정 스케치만으로 특정 비디오 객체 컷아웃 및 증강 객체 저작이 가능함을 보였다.

최근 애니메이션이 대중에게 널리 보급되면서 애니메이션을 제작 편집 하는 분야가 크게 각광 받고 있다. 그럼에도 불구하고 리눅스 환경에서 애니메이션분야의 편집은 윈도우 환경에 비해 미비한 실정이다. 본 논문에서는 보다 편하고 쉽게 Clay animation과 같은 stop motion animation을 리눅스 환경에서도 원활하게 제작 할 수 있는 Motion Space Prime을 제안한다. Motion Space Prime을 이용하여 디지털 캠코더의 영상을 실시간으로 캡쳐하고 사용자가 인터렉티브하게 편집하여 애니메이션을 쉽게 제작 할 수 있다.

In the previous research, we proposed a Kinetic typography font engine that can easily add motion to text with function call only. However, since it is aimed at constructing movements for a sentence, there is still inconvenience in the production of various kinetic typography motions in word or letter unit. We propose Kinetic Typical Extended Motion API(Application Programming Interface) that extends Kinetic Motion API. The extended Kinetic Typographic Font Engine aims to simplify the process of making kinetic typography in words and letters, including the kinetic typographic motion library provided as a function. In addition, various applications that can apply Kinetic typography A kinetic typography authoring interface is provided for facilitating the construction of a motion library for the robot.

영상매체를 이용한 영어 교육은 단순히 청각만을 이용한 방법보다 피교육생에게 사실적인 발음표현과 콘텐츠 몰입감 증대등의 측면에서 중요성이 높아지고 있다. 영어교육 콘텐츠에 등장하는 캐릭터들은 음성에 영어 발음에 맞추어진 사실적인 입모양을 표현키 위하여 많은 노력을 들이 있다. 이 논문에서는 교사가 손쉽게 영상 콘텐츠를 제작할 수 있도록 도와줄, 대화구문기반 교육용 콘텐츠 저작시스템을 이용하는 사용자에게 사실적인 lip-sync 애니메이션을 제작할 수 있도록 하여 교육의 능률을 높일 수 있도록 3D 캐릭터를 사례로 제작하였다. 폼 노아 마우스 차트를 활용한 입모양과 발음의 연관구조를 분석하고, 캐릭터의 컨셉 디자인에서 모델링, 맵핑, 애니메이팅 과정을 거쳐 익스포트로 최적화된 캐릭터데이터를 추출해 보았다. 입모양과 연계되는 손동작, 몸동작도 추후 연구에서 다루어질 때 보다 효율적인 교육용콘텐츠를 위한 3D캐릭터 제작이 될 것으로 사료된다.
