    Benefits

    Hypertextual audio/video storytelling has been a long-promised but rarely implemented feature of the Web and other hypertext systems. Recent developments in real-time streaming and database technologies now make it possible for most artists and Web developers to explore the expressive potential of this storytelling technique.

    This half-day course covers how to combine real-time RTSP audio/video streaming with database technologies to create dynamic documentaries and other presentations that assemble themselves based on input from the audience. Participants will learn how to prepare audio and video files for RTSP streaming; how to work with a streaming server; how to set up a database to describe audio and video content; what to consider when developing an interface for dynamic stories; and programming structures for bringing everything together. This course uses examples based on Apple's QuickTime technology and Macromedia Director, but other streaming and authoring platforms could be used to accomplish the same goals.

    Audience

    This tutorial is designed for producers and artists who work with digital media and hypertext. Audience members should have basic skills in Web production and a basic understanding of video production. This course uses examples based on Apple's QuickTime technology and Macromedia Director, but other streaming, authoring and database platforms could be used to accomplish the same goal.

    Format

    This course will be organized as a Half-Day Tutorial. It will be mostly lecture-and-demonstration format, but we may work with video clips collected during the conference, if it is possible to do so, and the attendees will have input on the selection and organization of the video hypertext clips.

    The components of the course are as follows:

    1. Introduction - What Is Streaming Hypertext?
    2. How to prepare audio/visual files for RTSP streaming
    3. How to work with a streaming server
    4. How to set up a database to describe audio and video content
    5. What to consider when developing an interface for dynamic stories
    6. Sample programming structures

    Origins

    This tutorial has not been presented at previous Hypertext conferences. I have presented parts of this tutorial to my classes at Marymount Manhattan College in New York City and the University of the Arts in Philadelphia.

    Instructor

    Susan Jacobson has a long history of working with streaming media and video conferencing technologies. She is currently an Assistant Professor of Digital Media at Marymount Manhattan College, where she directs the Digital Media Program and runs the Digital Media Lab.

    http://wwmm.ch.cam.ac.uk/

    Benefits

    XSLT is a leading technology for adding value to XML documents, and is an essential tool for anyone needing to process marked-up, semistructured information. It can generate any other markup language such as XHTML, Xlink, and Scalable Vector Graphics (SVG).

    The tutorial will show how complex documents (including datatyped material such as numeric quantities) can be processed by XSLT to give a range of hypermedia.

    Audience

    Audience. Anyone interested in content in XML, and adding value to (semi-)structured documents. Examples might be website managers, technical writers, publishers, librarians. Emphasis on getting started.

    Experience with XML syntax will be valuable (or a good knowledge of HTML). Participants will use openSource tools and should have a reasonable sense of adventure. Programming experience is not required.

    Format

    Full-day. At least 50% hands-on software tools

    Origins

    The XSLT tutorial is regularly presented on a commercial basis (2-day) and I have presented at many one-off conferences (SGML/XML/GCA, etc.)

    Instructor

    Peter Murray-Rust is at the new Unilever Centre for Molecular Informatics in Cambridge University. He is interested in informatics in STM fields and has developed systems in healthcare (especially drug regulation) and Chemistry. He was one of the original working group on XML and with Henry Rzepa ran the XML-DEV mailing list where many of the current ideas in XML took shape. He has developed markup languages to support STM and more particularly Chemical Markup Language for chemistry. He has given many lectures, demonstrations and tutorials on XML (including commercial training on- and off-site). In the Unilever Centre he develops 2-day workshops for industrial and academic scientists in molecular informatics including programming languages and XML.

    Usability of e-Learning Websites in Distance Education

    Benefits

    The tutorial will enable you to gain insight into the perspectives of instructors and learners in web-based distance education, including international students. Using the web to its full pedagogical potential requires a high level of self-study ability on the part of students. "Learning-to-learn" can be broken down into component skills, such as becoming more reflective, becoming a better time manager, developing good study habits, finding and applying relevant examples, and self-evaluation. Web-based learning presents specific challenges in each of these skill areas, and support may be needed. Websites can provide development of learning skills, and can give critical course information, study material and assignments in ways that help students become self-reliant. Multimedia and web resources enable students to make their own links and follow their own lines of investigation; however to ensure that they are fully supported, enhanced features or combinations of media are needed.

    An e-learning website can have many desirable features but it is still necessary to question whether it is usable. Notions of "usability" and "pedagogical usability" will be examined. Usability tests can reveal more than just the strengths and weaknesses of websites - they can shed light on assumptions and conceptions of users. A set of "challenges" is proposed that can be applied to a website during its development, to probe its pedagogical features. Subsequent evaluation can include consideration of the design of learning activities, and checking whether learning objectives have been met.

    Audience

    Designers and developers of educational websites and web-based learning materials; website editors and evaluators. The tutorial does not assume any knowledge of distance learning. It will be relevant to those who are new to developing web-based distance education, and anyone who has not had sufficient opportunity to reflect on pedagogical features.

    Format

    Half day. There will be a mix of presentation (perspectives of instructors and learners, learning to learn, website examples), discussion (usability test results), and a hands-on group exercise (applying "challenges" to a selected website).

    Origins

    The tutorial draws on extensive experience of design and evaluation of e-learning at the UK Open University. The website "challenges" are the outcome of a project that sought to bring together top recommendations from the research literature and the expertise of usability practitioners across the university campus.

    Instructor

    Dr Agnes Kukulska-Hulme is a Senior Lecturer in the UK Open University's Institute of Educational Technology. She chairs the web-delivered global Masters course, "Applications of Information Technology in Open and Distance Education", and co- directs the university's course website usability project (2001-3). She has presented numerous tutorials and workshops, e.g. at the WinWriters Annual Conference in Santa Clara and the European Online Help Conference in Copenhagen.

    Benefits

    The course will examine literary uses of non-linear structures by exploring electronic works. These works employ hypertext linking, narrative, game theory, and other techniques discussed in hypertext conferences and forums to form expressions and communicate in new ways.

    Participants will:

    • Gain an understanding in the techniques used to create web-based narratives
    • Explore the implications of hypertext and hypermedia for artistic endeavors
    • Explore the implications of current works for new avenues of research in hypertext and hypermedia
    • Broaden the understanding of new media as an artistic/literary genre

    Audience

    This course is designed for creators of artistic and literary hypermedia as well as hypertext and hypermedia researchers and programmers, and those who wish to read and enjoy new media.

    Format

    A half-day day course, in a computer lab with full internet access.

    • Explore several hypertext works (e.g, the Alt-X/trace and Electronic Literature Organisation prizewinners, web warp & weft) for reader, writer, critical, and researcher strategies and questions.
    • Discuss implications of these works for navigation and programming.
    • Look at a variety of forms that literary texts can take.
    • Study the conjunction of word, image, narrative structure, programming, and media tools as a means of storytelling.
    • Discuss the implications for analysing, archiving, and creating with various hypertext/hypermedia tools.

    Origins

    The writers workshops have been an integral part of the HT conferences since 1996. Many conferences have had joint discussions with new media artists and writers and hypertext/hypermedia programmers and researchers, which provide fruitful avenues for further inquiries. This tutorial extends the discussion and opportunities to look at literary hypermedia.

    Instructor

    The instructor will be from the trace Online Writing Centre: to be advised.

    The Hyperlink Interface - Design of Link Markers in Web and Hypertext Systems

    Benefits

    Participants will gain an understanding of the importance of hyperlink marker design and learn about the consequences of implicit design decisions of technology in use today -- primarily in the World Wide Web.

    A historical tour of hypermedia systems will introduce Hyperlink markers as the primary interface of hypermedia systems and show a variety of different visualization and interaction styles. Result of empirical studies on reading behavior will accompany the qualitative experiences with hypermedia systems.

    Differences between hypermedia systems research and Web practice will be studied and implications be drawn for both. Participants will learn how link taxonomies help categorize links; it will be discussed whether link types are useful for the hypermedia reader or author.

    Then, the focus is put on navigational questions assuming a user's perspective. Currently existing implicit link types in the Web will be demonstrated using a research prototype [2]. Different visualizations and interaction forms (links-on-demand) can be experienced by the participants.

    A discussion ends the tutorial and design implications will be rounded up.

    After a short technical introduction to HTML linking standards and Cascading style sheets, there will be room for the application of what was learned in a design session.

    Audience

    (a) Web authors (b) Hypermedia system authors

    Format
