Introduction (36 MB) (2:40) Ben Shneiderman
Bringing treasures to the surface: Previews and overviews in a prototype for the Library of Congress National Digital Library (104 MB) (7:30) Catherine Plaisant, Anita Komlodi, Gary Marchionini, Ara Shirinian, David Nation, Steve Karasik, Teresa Cronnell, and Ben Shneiderman
We worked with a team from the Library of Congress (LC) to develop interface design components for LC's American Memory collections of historical multimdeia materials. Our prototype illustrates the benefits of previews (such as samples, collections of thumbnails, and video previews) and overviews (such as timelines and automaticaly generated tables of contents) to facilitate the browsing of search results or entire collections.
Viewing websites using a hierarchical table of contents browser: WebTOC (71 MB) (5:40) David Nation
WebTOC is a new method of visualizing websites. It was first developed to browse large numbers of documents in the Library of Congress American Memory collections. WebTOC automatically generates a hierarchical table of contents of a site by following local links from the home page. The cumulative size, type, and number of items in branches of the hierarchy is shown graphically next to each link. WebTOC can also be used to show conventional file structures. A hierarchical multiple window WWW browser using
Elastic Windows (67 MB) (5:00) Ben Shneiderman and Eser Kandogan
Current WWW browsers are still primitive in that they do not support many of the user's navigational needs. We propose a new browsing interface based on the Elastic Windows approach with hierarchical windows and multiple window operations. It provides a flexible organization where users can quickly organize and restructure the pages on the screen as they reformulate their goals.
Using multimedia learning resources for the Baltimore Learning Community (92 MB) (6:50) Becky Bishop and Josephus Beale
The Baltimore Learning Community (BLC) is a community of middle school teachers who share resources and exchange ideas through the use of Internet technology. We demonstrate how teachers can prepare and present an online learning unit using resources suc h as high-quality videos, still images, and on-line text, accessible via broad-bandwidth networking. A dynamic query search interface is used to select a resources indexed by subject content and by Maryland State Performance and Assessment Program (MSPAP) outcomes.
Visual data mining using Spotfire (83 MB) (6:10) Ben Shneiderman
Human perceptual abilities are remarkable at spotting orderly and unusual patterns, but current tools have not made good use of these abilities. Now, information visualization strategies such as the starfield display (originated at the University of Mary land) are spawning exciting commercial software tools such Spotfire from IVEE Development ( Spotfire enables users to view tens of thousands of data points, with as many as five attributes per data point. It has powerful controls that enab le them to choose among dozens of attributes and then steer through the range of values within seconds. As the data points Educational philosophy for applying technology:
Relate-Create-Donate (67 MB) (4:30) Ben Shneiderman
This talk describes an evolving educational philosophy that can be a guide to applying advanced information and communication technologies. The philosophy is based on having students relate to team members to create something ambitious for some group outs ide the classroom. These authentic service-oriented projects can produce a high level of motivation among students and give them the satisfaction of building something useful for others.
Query previews in networked information systems: The case of EOSDIS (65 MB) (4:30) Catherine Plaisant, Tom Bruns, Ben Shneiderman, Khoa Doan
The Earth Observation System Data and Information System will access very large NASA databases over computer networks. Query previews present an overview of the entire database, where users make rough selections over a small number of attributes. Queries are then refined over all database attributes, elimating zero-hit queries often characteristic of networked databases.
As others see us: HCIL & the Teaching/Learning Theater Extract from "Your ticket to technology: Beyond the horizon" (131 MB)
Prepared by the Fairfax Network of Fairfax County Public Schools, Virginia, 4/23/97 (10:00) An interview with Ben Shneiderman and one of his students about the University of Maryland Theater/Learning Theater, followed by a discussion of user interface design and demonstrations of Elastic Windows, Dynamic Queries, and the Visible Human Explorer.
