Recently, mobile commerce is widely spread around the world according to fast growth of the mobile communication market. The existing digital document is not well fit in mobile commerce because of weakness of the hardware of mobile devices, low bandwidth of wireless communication, and the constraints of the size and resolution of the display. In this paper, we analyzed the elements of the digital document proper for mobile commerce based on wireless communication, designed the XML form for the digital document, and implemented the X-Auth which is an authoring tool for the XML digital document. X-Auth does not require that the author or user know XML. And also it makes it possible to create the digital document fit for the size of the mobile device display and therefore remove inconvenience due to the scrolls.

The design and implementation of the interaction for tangible user interfaces require in-depth knowledge in many different disciplines, such as device control, sensing and calibrating devices, interaction design, low-level programming, and performance tuning. Many trial and error iterations are needed to determine the proper combination of the interaction techniques while using available interaction devices and considering the characteristics of contents. As a result, it takes too much effort and time to achieve maximum usability. This paper introduces a tangible user-interface platform, which is fabricated using various hardware devices and an XML-based authoring tool, which is developed in order to relieve content creators of the burden of the above difficulties. Finally, we demonstrate our work by illustrating some example contents.

현재는 HTML(Hypertext MarkUp Language) 기반의 웹 페이지가 가장 널리 사용되고 있다. 그러나 사용자의 요구는 갈수록 높아져 2차원의 HTML로서는 표현하지 못하는 3차원 세계의 구현을 갈구하고 있다. 그래서 탄생한 것이 VRML(Virtual Reality Modeling Language)이며 현재 ISO 표준안으로 지정되어 있다. 사용자는 VRML로서 3차원 세계를 구현할 수 있지만, 가상세계의 규모가 커지고 복잡해지면서 문서편집기만으로 구축하기는 거의 불가능하다. 이런 이유로, 기존의 저작도구가 출현하게 되었고, 사용자에게 많은 편이를 제공하였다. 하지만, 이것 역시 몇 가지 문제점 (객체 설계 능력, VRML에 관한 지식 숙지, 일반 사용자에게 부담되는 비용) 때문에 VRML의 대중화를 방해되는 요소로 작용하고 있다. 그러므로 앞에서 제시한 문제점을 개선하기 위해, 사용자가 복잡한 가상객체를 디자인하는 것이 아니라 웹에서 이미 디자인된 객체와 개인자료를 합성하게 함으로써 일반 사용자에게 부담을 크게 줄일 수 있는 새로운 방법으로 개발했다. 그러므로, 본 논문은 인터넷 사용자라면 누구나 쉽게 가상공간을 제작할 수 있는 웹 기반의 저작도구인 WVRAT(Web based Virtual Reality Authoring Tool)의 설계 및 구현에 대해 기술한다.

As, the web technology and the computer hardware have been rapidly evolving, the convenient interface and reality are more important than the transmission time and the execution time. For satisfying these requirements, VRML is the most suitable language to implement virtual reality on the Web. However, it is too difficult for non-expert to use. It is also complicated to reconstruct VRML whenever it changes. In order to resolve these problems, this paper implements VRML Authoring Tool based on the web. Also, this paper analyzes the problem of the existing the cooperating VRML and database system, implements the extended VRML supporting system, and evaluates it with the existing system.

본 논문은 가상현실 어플리케이션을 제작하기 위한 가상세계 저작도구인 VRAT(Virtual Reality Authoring Tool)의 설계 및 구현에 대해 기술한다. VRAT는 3D desktop, immersive, reflexive metaphor를 지원하며 실시간 3D 센서 시스템과 폴리곤 렌더링 시스템을 기반으로 객체 지향적인 가상현실 운영시스템, 가상세계 데이터베이스, GUI를 통한 저작시스템으로 구성된다. 이들 하부 시스템은 완전히 결합되어 있어서 VRAT시스템을 사용한 응용프로그램의 수행중에 기존의 3D CAD 시스템등에서 제작한 모델을 가상세계내에 배치하고 이들에 행위양식을 부여하는 태스크를 지정하거나 입력장치인 센서를 모델이나 시점에 연결하여 조종하는 것이 가능하다. 제안된 시스템은 범용성과 이식성을 고려하여 UNIX와 X-Window 시스템을 기반으로 X11, GL, PIXRECT, VGA 그래픽 하부 시스템과 SGI, SUN, HP 등의 워크스테이션과 PC 상에서 구현되었다.

SMIL is a declarative markup language based on XML, which enables users to make effective multimedia presentations on the web by synchronizing media objects. In this paper, we design and implement a SMIL authoring tool which support Intuitive creation of web multimedia documents and diverse practical use of created information. Besides, creation, management and authoring module of SMIL document, it offers template interface depending on network bandwidth selection for general users to create multimedia presentation a convenient way. In addition, we implement SMIL document management facility for a large number of users, by connecting SMIL contents database sever.

Currently, the package tools and software development kits of Microsoft's Windows Media Technology provides users an environment to write, distribute and play multimedia contents. However, it is very difficult for common users to create a media streaming content using the Windows Media technology, because of its technical hardship. Therefore, we developed an easy-to-use authoring tool for multimedia streaming content which can be used in the Windows Media Technology environment. Our authoring tool is based on the web page templates by which HTML codes can be generated automatically. Using the existing streaming media authoring tool provided by the Microsoft, users have to code the temporal markers and the event script commands directly to the ASF(Advanced Systems Format) files or ASX (ASF Stream Redirector) format files. We developed an easy-to-use interface for insetting temporal markers and the event script commands to the ASF files by simple mouse clicking and dragging to minimize the effort of users for creating multimedia streaming content. In addition, we implemented an ASX file creation wizard that allows users to create ASX format file without coding ASX tags. We also implemented various web page templates where the ASF files and the ASX files can be embedded by just clicking the corresponding templates. The target web pages can be automatically generated from those templates and previewed directly on the web browser at the time of creation.

With the development of information communication and network technologies, ubiquitous era that supports various services regardless of places and time has been advancing. The development of such technologies have a great influence on educational environments. As a result, e-learning concepts that learners use learning contents in anywhere and anytime have been proposed. The various learning contents authoring systems that consider the e-learning environments have also been developed. However, since most of the existing authoring systems support only PC environments, they is not suitable for various ubiquitous mobile devices. In this paper, we design and implement a contents authoring system based on learning activities for u-learning environments. Our authoring system significantly improves the efficiency for authoring contents and supports various ubiquitous devices as well as PCs.

The Musical Slide Show MAF, which currently being standardized by MPEG, conveys the concept of combining several established standard technologies in a single file format. It defines the format of packing up MP3 audio data, along with MPEG-7 Simple Metadata Profile and MPEG-21 Digital Item Declaration metadata; with JPEC images and optional text, and synchronizes them all together to create a slideshow of JPEC image data associated to MP3 audio data during the audio playback. The implementation of Musical Slide Show MAF can be a music karaoke file where users can sing along while listening to the music, view the JPEG slideshow and reading the lyrics; or a story-telling file where users can listen to the narrated story by looking at the related illustration slideshow of the story In this paper we present the tool to producing the Musical Slide Show MAF contents. Regardless the knowledge of user on the MAF file format, the authoring tool simplify the manner of packaging several multimedia contents into single file.
