  • We propose a method using a transformation of an object and a scene tree in order to author MPEG-4 contents for mobile devices in this paper. The method transforms media objects in the scene into geometry objects in order to reduce initial loading time of the contents, and reduces an external form of each object in a scene of the content for presenting it efficiently on the small interface of mobile devices. Therefore, the contents for mobile devices are reconstructed by the method. An original object in the scene is presented on a mobile device when a user clicks a related geometry object. The method was applied to a conventional authoring tool, so we could find that the method showed an efficient presentation of MPEG-4 contents on mobile devices.

  • 디지털 방송 기술의 비약적인 발전은 그 수요와 공급을 늘려가며 디지털 컨버전스 시대의 매력적인 산업으로 디지털 방송을 급부상시키고 있다. 이러한 발전 추세를 반영하듯 국내 아날로그 방송 서비스는 2012년을 기점으로 종료해야 하는 운명을 맞아 그 가속화는 더욱 빨라질 것으로 예상된다. 한편, 디지털 방송의 한 분야인 지상파 이동 멀티미디어 방송(Digital Multimedia Broadcasting, DMB) 역시 시류에 발맞추어 디지털 방송과 모바일 환경의 결합이라는 추가적인 이점을 안고, 몇 가지 서비스를 선보이고 있다. 하지만 이와 같은 이점에도 불구하고, DMB 서비스는 교육 혹은 광고 분야 등의 뚜렷한 수요의 증가를 가져오는 콘텐츠에 대한 제작과 배포가 쉽지 않고, 그 방법과 기준이 혼재하는 어려움으로 인하여 DMB가 지닌 무한한 가능성에 비해 크게 이슈화가 되지 못하고 있는 실정이다. 본 연구에서는 이러한 점에 착안하여, 지난 연구들에서 얻은 경험을 밑거름 삼아 기본적인 콘텐츠의 제작 및 배포는 물론 DMB 서비스에서 특화될 수 있는 콘텐츠를 더욱 쉴게 생성할 수 있으며, 기술적으로는 3차원 객체를 지원하는 부분을 보강하며, 편리한 인터페이스 등을 포함하는 저작 도구를 개발한다. 이를 위해 기존 연구들에서 다루어온 MPEG-4 Part 11 : BIFS(Binary Format for Scenes)를 기반으로 국내외에서 연구된 기존의 저작도구들을 비교하며, 새로운 아이디어들을 접목시켜 향후 DMB 서비스에서 효율적으로 쓰여 질 수 있는 저작도구를 개발한다.

  • 무선 인터넷 개발은 기술 표준, 무선 단말기, 무선망이 가지는 다양성(diversity)과 이질성(heterogeneity)으로 인해 쉽게 접근하기 어려운 현실이다. 무선 단말기가 가지는 인터페이스의 제약과 무선망의 대역폭의 제한으로 인해 유선인터넷 수준의 컨텐츠를 기대했던 사용자들에게 실망감을 안겨주는 것도 사실이다.(중략)

  • This paper presents the development of a certain highly efficient authoring tool for constructing realistic 3D virtual space using image-based rendering techniques based on a virtual space map. Unlike conventional techniques such as TIP, for constructing a small 3D virtual space using single image, the authoring tool developed herein produces a wide 3D virtual space using multiple images. This tool is designed for constructing each small 3D virtual space for each input image, and for interconnecting these 3D virtual spaces into a wide 3D virtual space using a virtual space map. The map consists of three elements such as specific room, link point and passageway, and three directions. It contains various information such as the connection structure, the navigation information and so on. Also, the tool contains a user interface that let users construct the wide 3D virtual space easily.

  • According to the increasing interests of medical information services for healthy living, the multimedia authoring tools for medical information service contents are strongly required. In this paper, a new multimedia authoring tool supporting user-friendly interfaces is implemented, which is based on SMIL(Synchronized Multimedia Integration Language) producing Web-based multimedia contents. The implemented authoring tool in this paper not only provides functionalities to play, verify and modify the partial contents immediately but also offers capabilities to insert multimedia objects into contents with ease. The multimedia contents containing disparate healthcare and medical information can be easily designed with this tool. The enhanced usability of this tool can contribute to the realization of diverse medical information services.

  • This paper describes a new visual VR authoring tool called DEVISE (Drawing Environment for VR-based Inquiry-learning Science Education) which is designed to support scientific inquiry learning. DEVISE allows users with no programming expertise to easily build the science inquiry learning VR contents by using 2D drawing interface to place 3D objects and specify properties of the virtual worlds or objects. This paper first describes the related works of VR authoring tools and inquiry learning virtual environments. It also explains SASILE, an integrated virtual environment system for supporting science inquiry learning, and its problems. Then, it describes DEVISE system components and its workflow, and it discusses the observation results of user evaluations of developing science inquiry-learning VR contents.

  • As an IETF standard protocol, WebDAV provides infrastructure for managing and authoring resources and supports asynchronous collaborative authoring on the Web. The CoSlide server is an extension of the Jakarta Slide WebDAV server, providing various workspaces and collaborative services through the WebDAV protocol. The CoSlide server supports workspaces for storing and sharing information of various users, and provides environment for effective collaborative authoring. Actual collaboration activities are performed through a collaboration client software which provides collaboration services along with the CoSlide server. In this paper, we describe the development of the CoSpace client which operates in association with the CoSlide server, presenting effective collaborative environment. The CoSpace client provides user interfaces for accessing and controlling the resources of each workspace on the CoSlide server. In particular, CoSpace provides the facility to launch an authoring application from its workspace view, automatic locking, and downloading the content to be edited, and resource movement using mouse drag & drop.

  • 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.

  • In this paper we proposed EduCODE for educational contents development method and designed the system to support EduCODE. There are four models in EduCODE such as domain model, navigation model, abstract interface model, and asset model. The method includs graphic notations for contents structure. The system to support EduCODE consisted of authoring module and run-time module. The authoring module automatically generates ADL SCORM XML code using specifications produced by EduCODE and the code is serviced to a client by run-time module and web server.
