Based on the basic concepts and roles of the Science Museum, the research and development of the "Sound Light" interaction exhibition contents and experience exhibition space aimed at providing the exhibition, education and experience of scientific principle directly related to daily life will be implemented in the "Sound Light" exhibition space of the Gwangju National Science Museum. The scope of the research is to define the conditions and elements of the museum's hands-on exhibition by examining the case and status of the existing science museum's experience-type content prior research, and research and development of experience-type exhibition scenarios and contents for children based on them. The results of this research and development content are firstly developed with the theme of light and sound as interactive hologram experience content. Second, by multi-faceted media facade through projection mapping by multiple projectors, visual wide and spectacular screen composition and animation are realized. Third, visitors-oriented exhibitions and experiences that can interact with visitors by moving various colors and sounds together. Finally, interactive content is provided through hologram interfaces through hologram screens to encourage active participation of many visitors in viewing rather than simply delivering exhibition information and to promote revisiting the exhibition. Through a series of studies, it was possible to research and develop contents and experience exhibition spaces with theme park characteristics, which are the trend of science museums.

Since the Industrial Revolution in the 18th century, the production system adopted mechanization and mass production to popularize and standardize overall society. The architectural space removed basic desire of men on the decoration to neglect historical and regional continuity of the architecture and to make uniform designs, so that human sensibility and emotion were excluded. The architectural space had arbitrary and functionalism features in accordance with such a social change to display abstract space having no personality. The limitation expanded value of the space that was not lot possession and residence but for communication with men to express object factors. However, the object factors of the space were expressed in each factor consisting of either material factors or non-material factors. This study investigated interaction of the space by both expressive interaction and potential interaction to find out key words for making frames of the investigation and to examine cases comprehensively. The purpose of the study was to recover relations between the space and men in horizontal way and mutual communication and to present possibility integrating men and space.

In this study, we propose a 3D virtual reality based presentation training system to help implement the virtual presentation environment, such as the real world, to present it confidently in the real world. The proposed system provided a realistic and highly engaging presentation and interview environment by analyzing the speakers' voice and behavior in real time to be reflected in the audience of the virtual space. Using HMD and VR Controller that become 6DOF Tracking, the presenter can change the timing and interaction of the virtual space using Kinect, and the virtual space can be changed to various settings set by the user. The presenter will look at presentation files and scripts displayed in separate views within the virtual space to understand the content and master the presentation.

Rather than a directing method of existing animations, VR animation needs a different method of direction. Existing animations were displayed on a screen in movie theaters. But using an existing direction method for the 360° perspective in a VR animation makes it difficult for the user's gaze to move in a way the directors have intended. I analyzed 3 VR animations with a theoretical background of Rudolf Arnheim's visual perception theory and Bruce Block's visual factors that bring high attention. In the process of perception of space, focus on the gaze, movement of the gaze, the 'movement' factor was used most often to attract the gaze. An interactive VR animation attracts user's gaze by allowing users to participate in important points of the story. With an analysis of the animation, it proposed a gaze attraction through the movement of the character with an interaction directing method for reducing motion sickness. Also, it proposed intuitively attracting gaze movement by using GUI and attracting user's participation by using an interactive event with an interaction directing method of storytelling comprehension. With two types of directing proposal, we expect it to be utilized as a basic research method for attracting users to be immersed in storytelling while reducing cyber motion sickness, which is a problem in VR animation.

가상 현실과 현실 세계가 공존하는 증강 현실은 현재 및 향후 실감미디어 콘텐츠에 중요한 역할을 할 것으로 기대된다. 증강 현실은 게임, 엔터테인먼트, 교육 분야 등에서 응용에 따라 다양한 기술들의 결합이 요구된다. 본 논문에서는 교육적 효과를 주는 버블 포핑 증강 현실 기법을 제안한다. 버블 포핑 시스템은 비디오 입력용 웹캠, 마커 패턴 영상, 그래픽 구 버블 객체, 그래픽 마우스 등으로 구성된다. 일반 마우스의 이동에 따라 그래픽 마우스가 3차원 공간상에서 이동하면서 버블과의 충돌이 발생하게 되면, 충돌시 발생하는 버블의 이벤트로 동적 움직임, 터짐 등의 버블 효과를 구현할 수 있는 방법을 제안한다. 충돌 검출은 카메라와 마커 패턴의 좌표계 및 버블의 3차원 공간위치, 그리고 3차원 모델 데이터를 이용하여 구현한다. 제안 시스템은 ARToolkit을 기반으로 제작되었으며, 시각적인 마커 기반 시스템으로 버블의 움직임과 사용자의 인터랙션을 통해, 버블 포핑의 증강현실을 전달한다. 향후, 현재 개발 중인 포스 피드백 기능이 있는 진동촉각공간 햅틱 마우스와 접목하여 보다 실감적인 증강현실 기술을 개발할 예정이다.

Interactive space became one of the major design paradigms. For elevating the interactive effect in this, we need user-centered design methodology which uses the influential factors on the interactivity. As the second paper of three-linked studies for the interactivity in the interactive space, this research analyzed the interface factors' specific attributes for supporting behavioral participation. 'Interface' is one of three main factors on the interactivity(Intersubject/Interface/Interaction). Its role in the interactive space is to induce or support user's participations which bring the interactive changes into the designs. Qualitative case analysis was the main method and 30 cases were investigated. 'Individual analysis-Transitional description-Generalization' were the progressive steps for case analysis. As final results, 17 attributes for supporting behavioral participation were analyzed.

Our research was performed in order to implement a new pointing device for human-computer interactions in a collaborative environments based on Tiled Display system. We mainly focused on tracking the position of an infrared light source and applying our system to various areas. More than simple functionality of mouse clicking and pointing, we developed a device that could be used to help people communicate better with the computer. The strong point of our system is that it could be implemented in any place where a camera can be installed. Due to the fact that this system processes only infrared light, computational overhead for LED recognition was very low. Furthermore, by analyzing user's movement, various actions are expected to be performed with more convenience. This system was tested for presentation and game control.

Recently, many human-friendly communication methods have been studied for human-machine interface(HMI) without using any physical devices. One of them is the vision-based gesture recognition that this paper deals with. In this paper, we define some gestures for interaction with objects in a predefined virtual world, and propose an efficient method to recognize them. For preprocessing, we detect and track the both hands, and extract their silhouettes from the low-resolution hand images captured by a webcam. We modeled skin color by two Gaussian distributions in RGB color space and use blob-matching method to detect and track the hands. Applying the foodfill algorithm we extracted hand silhouettes and recognize the hand shapes of Thumb-Up, Palm and Cross by detecting and analyzing their modes. Then, with analyzing the context of hand movement, we recognized five predefined one-hand or both-hand gestures. Assuming that one main user shows up for accurate hand detection, the proposed gesture recognition method has been proved its efficiency and accuracy in many real-time demos.

In a ubiquitous computing environment, people more and more become to use multiple displays. When using such ubiquitous displays, it is needed for users to seamlessly interact with the displays for a certain content. In this paper, we propose a seamless interface that allows users to see photos across multiple displays. Many photos can be displayed on a screen at the same time because they are shown in 3D space. And a group of photos is represented using a cube metaphor. A user can manipulate photos directly using a touch screen and also see the photos continuously using PDAs when the user moves to other places. In addition, the user can interact with the photos seamlessly using another display. The developed system was designed to interact according to user's movements and not to draw user's attention too much as a kind of ambient display. Using RFID and ultrasonic sensors it recognizes a user and the user's proximity to the display, and then automatically determines the screen image and the user interface accordingly.
