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.

This study examines the digital era's fashion system and defines fashion leaders in the system. The study was based on a theoretical review and a research survey to verify the theoretical findings. The results are follows. The critical changes in the fashion system are expansion, cyclical direction and closer distance between producer and consumer. By inflow of media to a new channel, a layer of consumers was extended and the range of celebrities participating in the fashion industry has expanded dramatically. Simultaneously with the change from vertical communication to cyclical and interactive, the direction of communication was re-routed through diverse media. Crowd sourcing activated through two-way communication service has increased consumer opportunities to participate in production and consumption. Fashion leaders have changed significantly under this new system. The range of celebrities participating in the fashion system has increased and different fashion leaders have appeared. An interactive and cyclical fashion system has been established through media innovation; consequently, the influential power of celebrities and individuals for direct participation in the fashion system directly has increased significantly.

The MPEG-4 standard is aimed to define an object based audiovisual coding standard to address the emerging needs from interactive broadcasting. Since a broadcasting program is created on the basis of its objects, it is considered that MPEG-4 is most suitable for interactive broadcasting contents production and it can be retrieved in terms of its properties. But, there is no system that protects the copyright of digital contents and manages copyright and possibility that contents producer and author's copyright receives infringement at process that exchange contents mutually rose very. Therefore, we need to control and distribute contents according to user's permission rights. In this paper, we present the authoring system based on MPEG-4 IPMP for copyright and protection of MPEG-4 contents. The main features of the proposed approach is to provide an MPEG-4 compliant IPMP authoring system in a plug-in type along with standardized interfaces, which is to be able to incorporated into an existing MPEG-4 content authoring system. In this way, it is capable of authoring content to the MP4 file format while accommodating protection and management of content in a unified way. Furthermore, it also allows a user to edit and/or author IPMP information in a more efficient way by offering form based user interfaces.

Objective: This paper describes the process and results related to the development of gesture recognition-based natural user interface(NUI) for vehicle maintenance e-Training system. Background: E-Training refers to education training that acquires and improves the necessary capabilities to perform tasks by using information and communication technology(simulation, 3D virtual reality, and augmented reality), device(PC, tablet, smartphone, and HMD), and environment(wired/wireless internet and cloud computing). Method: Palm movement from depth camera is used as a pointing device, where finger movement is extracted by using OpenCV library as a selection protocol. Results: The proposed NUI allows trainees to control objects, such as cars and engines, on a large screen through gesture recognition. In addition, it includes the learning environment to understand the procedure of either assemble or disassemble certain parts. Conclusion: Future works are related to the implementation of gesture recognition technology for a multiple number of trainees. Application: The results of this interface can be applied not only in e-Training system, but also in other systems, such as digital signage, tangible game, controlling 3D contents, etc.

Nowadays, many computer games based on NPR(Non-photorealistic Rendering) techniques have been developed due to their distinctive visual properties. However, only limited methods of NPR techniques have been exploited in producing computer games and amongst them cartoon-style rendering techniques especially has had the special interest. In the paper, we suggest an effective rendering method of comic-book style that will be applicable to computer game. In order to do, we first characterize the properties of comic-book from comparing two visuals: celluloid animation and comic-book. We then suggest a real-time rendering method of comic-book style represented by outline sketch, tone, and hatching. We finally examine its effectiveness by observing the game developed using the method.

BCI (Brain-Computer Interface) is a way to control computer by using the human brain waves. As the hardware using brain wave technologies has developed, former expensive and big sized brain wave measuring devices have recently become much smaller and cheaper in their prices, making it possible for the individuals to buy them. This predicts them to be applied in various fields of multimedia industry. This thesis is to give an insight into whether the BCI device can be used as a new gaming device approaching it in a game designing point of view. At first, we proposed game play elements that can effectively utilizing the BCI devices, systematize, and produced a game prototype adopting the BCI device based on such game play elements. Next, we verified it with statistical data analysis to show that the prototype adopting the BCI device gives more clear and efficient controls in its game play than a game of only adopting keyboard & mouse devices and analysis verified that BCI-based game play elements provide users with a more intuitive and interesting experience than traditional non-BcI-based game play elements. The results will give a guideline for effective game design methodology for making BCI based games.

This study has a main purpose on discussing the issue how the construction of film narrative will be changed by audience's desire to intervene into film narrative through the active participation, out of watching a film passively in movie theater. Compared with the collective theatergoing experience in big screen was defined as the past cinematic identity, the absolute value of movie theater fragmented increasingly in the era of media diversification facing with digital media convergence. As this situation can be compared with "the author's death" Roland Barthes predicted on the mono-media of the book, thus, we are to take the time to discuss the new emerging 'movies'. The most important thing in this discussion is the aspect of the transformation of narrative in the future screening. Especially, while 3 act structure and configuration evoking a catharsis in film narrative are elements defining aspect of the past narrative, then, the future narrative in film will change to the structure interacting with audience actively. This paper had a discussion how could be possible the aucience interaction in only movie valuing the passive experientiality uniquely in screening over the other media through investigating the attempts of interactive cinema so far and the possibility of future.

This paper describes the development of the media art environment concept, in which the user's interaction becomes visual arts in both digital and analogue media. It describes AD-Trace, an experimental media art component that investigates the aesthetic and technological possibilities through the development of interactive media artworks that utilizes that the traces of the user's interaction. The AD-Trace consists of three design components: Analogue Trace, Digital Trace, and Interaction Metaphor to guide user interactions with user's understanding. Three artworks are proposed to demonstrate the real world applications of the concept: AD-PD(analogue digital picture diary), AD-Star (analogue digital star), and AD-Map (analogue digital map).

In this paper, we propose a Real-time Interactive Shadow Avatar(RISA) which can express facial emotions changing as response of user's gestures. The avatar's shape is a virtual Shadow constructed from the real-time sampled picture of user's shape. Several predefined facial animations overlap on the face area of the virtual Shadow, according to the types of hand gestures. We use the background subtraction method to separate the virtual Shadow, and a simplified region-based tracking method is adopted for tracking hand positions and detecting hand gestures. In order to express smooth change of emotions, we use a refined morphing method which uses many more frames in contrast with traditional dynamic emoticons. RISA can be directly applied to the area of interface media arts and we expect the detecting scheme of RISA would be utilized as an alternative media interface for DMB and camera phones which need simple input devices, in the near future.
