In this course we will have two guest lectures and a few guest presentations. Guest lectures are held by Keith Andrews and Jay Bolter. Guest presentations will be given by Eric Ayers, Veerasamy Aravindan, and Andy Wood.
Hyper-G: The Next Generation Web Solution
Keith Andrews, IICM, Graz University of Technology, Austria
GVU Brown Bag Talk, Thurs. 11th April 1996, 12:00
Guest lecture in CS 6364 on Fri, 12th April 1996, 11:15 (?) room 201
Abstract
Interest in information technology on the Internet is currently exploding. Hyper-G is a "second generation" Internet information system being developed jointly by the Institute for Information Processing and Computer Supported New Media (IICM) of Graz University of Technology, Austria and the Institute for HyperMedia Systems (IHM) of JOANNEUM RESEARCH, Graz, Austria.
Hyper-G provides advanced facilities for the structuring, maintenance, and management of large amounts of information: these include bidirectional links, graphical link maps, guaranteed link consistency, hierarchical structuring, rich metadata, fully integrated full text and attribute searches, and user accounts, groups, and access rights. The Hyper-G server services both World Wide Web and Gopher requests. Hyper-G's own authoring tools provide sophisticated navigation and visualisation aids and interactive facilities for information structuring, document and link editing, batch uploading, and communication.
Biography
Keith Andrews works at the Institute for Information Processing and Computer Supported New Media (IICM) at Graz University of Technology, in Austria.
His research interests include network information systems, hypermedia, human-computer interaction, computer graphics, and virtual reality. He holds a B.Sc.(Hons) in Mathematics and Computer Science from the University of York, England and an M.Sc. in Technical Mathematics from Graz University of Technology, where he is currently completing a Ph.D.
Having lead the Harmony project (the Unix/X11 client for Hyper-G) for several years, he is currently project leader for the VRweb VRML viewer and is pursuing research in the emerging field of information visualisation. He teaches graduate-level courses on Multimedia Information Systems and Human-Computer Interaction, and has given numerous Hyper-G talks and courses.
Hypertext, Computer Graphics and the Idea of Information Visualization
Jay D. Bolter, Georgia Institute of Technology, School for Literature, Communication & Culture
Guest lecture in CS 6364 on Wed, April 17, 1996, 4:30
Abstract
This will be a very informal presentation of some thoughts on visualization
and spatialization of information structures. Where does the idea of
information visualization come from? What are some of its deep intellectual
and cultural roots? I will argue that one of the roots is the myth of
transparency: the notion that pure perception is a more effective (because
more immediate) way of understanding the world than symbol
manipulation--that "seeing" is better than "reading." I will demonstrate
Storyspace as an example of an early (1980s) attempt to visualize hypertext
and discuss why it never succeeded as a model for information
visualization. We will go on to discuss why the Internet seems to be
thriving despite the lack of widely available tools for visualizing its
structure.
Biography
Jay D. Bolter is professor at Gatech's LCC. His primary interest is the social and cultural impact of computers and the use of computers as new medium for verbal and visual communication. He co-developed Storyspace, a hypertextual computer program, in collaboration with author and educator Michael Joyce. He is working on the use of MOOs and the Internet as collaborative pedagogical environments. Graduate teaching includes courses in the rhetoric of electronic environments, virtual reality, and the Internet as a medium for hypertextual design.
Guest Presentations
- Eric Ayers: Graphical History Browser (Wed, April 17, 1996, after Jay Bolter's talk)
- Abstract from Eric's paper at WWW4: Using Graphic History in Browsing the World Wide Web
Users of hypertext systems often find themselves eagerly following hypertext links deeper and deeper into a hypertext web, only to find themselves "lost" and unable find their way back to previously visited pages. As navigation aids to help users orient themselves in the Web, browsers often provide a list of the documents a user has visited, a way to move forward and backward along previously traversed links, and a quick way to return to a home document. Still, users often have trouble revisiting a page that was previously viewed in a session, especially after many invocations of the backtracking shortcuts.
MosaicG is derivative work of NCSA Mosaic version 2.5 which enhances the history-keeping facility of the browser by providing a two-dimensional view of the documents a user has visited in a session. It is intended as an easy-to-use aid in navigating a collection of hypertext documents. By presenting titles, URLs, and thumbnail images of the documents a user has visited in a session, the Graphic History View allows a user to easily recognize a previously visited document and provides an easy way for the user to revisit that document and analyze the structure of a set of hypertext documents.
- Veerasamy Aravindan (CoC)
- Samy will describe his query visualization system.
- Andy Wood
- Andy will tell us about the hyperspace system (formally known as Narcissus). The hyperspace visualisation system allows you to build maps of
parts of the web, producing output that looks reminiscent of
the ball and stick models that you find in chemistry departments.
For some more information have a look at the the hyperspace section on the ressources page.
