In this paper, we developed an interactive animation authoring tool and developed the Android based interactive edutainment contents. The authoring tool for creating interactive animations developed in this paper is based on a graphical user interface, so users can easily create interactive animations. Interactive animation contents created by this authoring tool can be created as images and xml files so that they can be used directly on mobile devices. In order to increase learning efficiency for children, Android-based interactive edutainment electronic storybooks, which is implemented using this authoring tool, provided a recording function to listen to the parents' voice as well as an interactive action in which the characters move in accordance with the story line. We also provided a STEAM game that combines creativity and imagination with creative science and technology. Therefore, by creating the edutainment contents through the proposed authoring tool for interactive animation, various interactive animation contents could be produced more easily than the code implementation method. Through this study, I hope that it will be helpful for the development of various interactive edutainment contents to provide educational contents considering the quantity and quality to infants.

디지털방송의 애플리케이션(Xlet)은 시청자와 방송프로그램간의 상호작용에 중요한 역할을 담당한다. 현재 이러한 애플리케이션 UI는 평면이미지로 구성하는 것이 대부분이며 화면상 영역은 2차원으로 제한된다. 본 논문은 이러한 2차원의 평면적인 느낌을 극복하고 3차원이 가진 다양한 이점을 살리기 위한 3차원 UI구현방법을 제시한다. 이를 위해, 본 논문은 가상의 3D System, Virtual Timeline, Animation Model 등을 구성하였다. 3D System이란 UI가 3차원 좌표계를 가지기 위한 환경을 말하며, Timeline과 Animation Model은 제한적인 성능의STB에서 보다 진보된 애니메이션을 UI에 적용하기 위한 기법이다. 이들은 다양한 애플리케이션 제작, 서비스 개발 등에 응용이 가능하다. 디지털방송은 매우 빠른 속도로 발전하고 있으며 새로운 형태의 서비스가 속속 등장하고 있다. 이러한 흐름에 발맞춰 3D UI는 기존의 TV 화면에서 보다 진보된 형태의 사용자 인터페이스의 모습을 보여줄 것이다.

Recently popular media, book, has problems to satisfy a child who wants to be a character in a story, because it just transmits fixed story. Therefore, many people are interested in interactive contents that are changed variously by user's acting in multimedia division. This paper introduces an interactive pop-up book system that can control a story of book by interesting interactivity. This system suggests a special story graph that transforms a linear architecture story to a interactive story by traversing diverse node We focus to make a special pop-up book interface and wind blowing interface for physical environments to have interesting and familiar user interaction, and to conclude by user studies. We also investigated user preference for various interactive story paths, so we can excluded unnecessary stories and surveyed to compare before the excluding and after. Finally, story paths that user prefers are introduced in the Interactive Popup Book System.

We are developing a simple low-cost wind velocity sensor based on small microphones. The sensor system consists of 4 microphones covered with specially shaped wind screens, 4 pre-amplifiers that respond to low frequency, and a commercial sound interface with multi channel inputs. In this paper, we first present the principle of the sensor, i.e., technique to successfully suppress the influence of external noise existing in the environment in order to determine the wind velocity and the wind direction from the output from a microphone. Then, we present an application for generating realistic motions of a virtual tree swaying in real wind. Although the current sensor outputs significant leaps in a measured sequence of directions, the interactive animations demonstrate that it is usable for such applications, if we could reduce the leaps to some degree.

This study suggests a model of experimental visual artworks with interactive art forms in which 2-D paintings are transformed to interactive 3-D animation works. Multimedia programming was employed to evolve objective still paintings to the animation of computer 3-D images with respect to visual ideas derived from visual components in the still painting and to response to the reactions users. The format and technique of the art works are based upon the contents developed by the author and the research materials are selected from the surrealistic paintings of tile world-famous Belgian painter, Rene Magritte. In the present paper, following topics are discussed in detail: a study of various visual cases occurring in transforming still paintings to animation works containing interactive components; a study of 3-D imaging and image processing techniques to transform 2-D paintings to 3-D images; animation techniques for interaction and overall structuring techniques; multimedia programming and user interface.

As obtaining information via the Internet has increased recently, the importance of web-based user interface more than ever is being emphasized. The purpose of this study is to improve the sliding structures of submenu in pull-down menu for improving web user interface. Animation techniques applied to the submenu of the pull-down menus that are being used at many web sites have very monotonous sliding structures. In order to solve these problems, a new sliding algorithm based on enlarging/reducing and moving animation techniques with direction control in pull-down menu is proposed. As a result, the proposed method can not only improve visual effects significantly but be also easily applied to the implementation of the web-based user interface in comparison with the previous pull-down menus. Finally, experiments on application of the proposed sliding algorithm to responsive image slider show that the proposed method can achieve good results. Further studies taking into account performance are needed to implement web-based interactive contents using the proposed method.

In this paper, we propose user-centric immersible and interactive electronic book based on the interface of tabletop display. Electronic book is usually used for users that want to read the text book with multimedia contents like video, audio, animation and etc. It is based on tabletop display platform then the conventional input device like keyboard and mouse is not essentially needed. Users can interact with the contents based on the gestures defined for the interface of tabletop display using hand finger touches then it gives superior and effective interface for users to use the electronic book interestingly. This interface supports multiple users then it gives more diverse effects on the conventional electronic contents just made for one user. In this paper our method gives new way for the conventional electronics book and it can define the user-centric gestures and help users to interact with the book easily. We expect our method can be utilized for many edutainment contents.

Simulation tools are widely used for performance evaluation of newly proposed systems. However, many industrial simulation projects fail to attain the original goals ,especially when very complicated decision logics of the experienced operatorsare needed to be modeled. We propose a technique to overcome the oabstacles. In the proposed technique, complicated decision logics are not directly modeled but an interface for interactive input is provided in the model. While running the simulation model in concurrent animation mode, whenever operator's decisions are needed an interfce screen is displayed for operator's decisions. The operator then makes decisions using the information which is provided by the animation proces itself. This technique was successfully applied to an industrial simulation projects in which alternatives were evaluated for increasingthe color lot size of car print shop.

As increasing emphasis is being placed on user experience design, the RIA technology is widely deployed for user interface and software operation on embedded devices including cell phones and TVs. In particular, RIA-based IPTV enables creation of various interactive contents via sophisticated animation and various input devices. This paper proposes a service framework for emotional contents on broadcast and communication-converged IPTV systems. We design a programming interface extension for IPTV-based flash contents and develop a prototype of flash runtime with the extended programming support. Since the proposed runtime was carefully designed to fully utilize the built-in graphic acceleration hardware in media processor, it supports high resolution graphic animation in resource-constrained IPTV environments.
