A Live Satellite TV Broadcast 

December 9, 1992, Wednesday 11am-5pm EST 
University of Maryland Instructional Television
Organized by Ben Shneiderman
Audience: User interface designers, programmers, software 
engineers, interface evaluators, managers in the computing and 
communications fields, technical writers, human factors 
specialists, trainers, marketing personnel.
Overview: Four leaders in the field present their perspectives on 
why the user interface is a central focus for expanding 
applications of computers in business, education, the home, etc.  
They offer their visions and suggest exciting opportunities for 
the next decade's developments.  Demonstrations, new software 
tools, guiding principles, emerging theories, and future scenarios 
will be presented.
Enrollment:  This symposium will be broadcast live by satellite 
from the University of Maryland Instructional Television System 
via C Band.  In order to view the broadcast, access to a satellite 
dish is necessary.  Contact your organization's training office to 
ask if they can arrange a satellite downlink.  If your 
organization does not have a satellite dish, contact your local 
college or university teleconference office to ask them to help 
set up a downlink.
Cost to view this symposium is $160 per person for 1 - 9 people, 
or $1,600 site license for groups of 10 or more.  Send check, 
money order,  or purchase order (made out to the University of 
Maryland) to:

This program will also be broadcast on the National Technological 
University (NTU) satellite network.
Special Videotape Offer:  Your organization may videotape this 
symposium at no extra cost.  If you cannot watch the broadcast 
live or make a videotape, ITV will make a videotape for you at the 
cost of $1800.  All videotape purchases are restricted for 
internal use by your organization only.

     Information Visualization: Sight for Sore Eyes
The widespread use of graphic user interfaces has altered the 
cognitive balance, shifting attention to more visual approaches to 
many tasks.  Dynamic queries which employ direct manipulation 
widgets such as sliders to set value ranges, are enabling users to 
find information rapidly and to develop intuitions, recognize 
trends, and spot exceptions.  Treemaps, a space-filling mosaic 
approach to representing hierarchies, give users x-ray vision for 
computer directories, stock portfolios, and sales charts.  Visual 
approaches to enduser programming by demonstration are maturing.  
Demonstrations, empirical results, and guidelines for designers 
are offered.

    Computer Supported Collaborative Work
Computer-supported cooperative work represents the next stage in 
our understanding of the computer tool; it supports the intense 
communication exchanges and collaboration activities that we carry 
out with others.  New directions range from providing a dynamic 
shared memory for documenting and running face-to-face meetings to 
simulating the presence of distant co-workers through miniature 
video and audio technology.  These directions represent 
fundamental changes to work practice (for example, telecommuting), 
to consensus forming and team building (for example, group 
decision support systems), to work products (for example, shared 
design environments), and particularly to user interface design.   
Demos and videos illustrate novel interface solutions and reveal 
criteria for successful products.
Marilyn Mantei is Associate Professor of Computer Science and of 
Library and Information Science at the University of Toronto.  
While a faculty member at the University of Michigan, she started 
the Human-Computer Interaction Laboratory, served as Director of 
Research and Development for a microcomputer software company and 
as Senior Scientist at the EDS Center for Applied Research.  At 
EDS, she developed and conducted research on the Capture Lab, a
computer-supported meeting room.  At Toronto, she heads the 
CAVECAT project, a video desktop conferencing research initiative. 
Dr. Mantei has been a SIGCHI officer, has chaired the CHI'86 
Conference on Human Factors in Computing, and is co-chairing the

     Virtual Worlds: Why? and When?
In the next few years virtual interfaces will revolutionize the 
way that humans think with computers.  Rather than requiring 
humans to become 'computer-like' to operate and program these 
machines, virtual interfaces allow the computer to become 'human-
like', by providing an immersion of the senses into a three-
dimensional visual, acoustic, and tactile medium.  The high 
bandwidth to the brain produced by these interfaces will extend 
human intellect and provide new applications in business, 
medicine, education, communication, and entertainment.  This 
presentation traces the history of virtual interfaces, discusses 
current research and upcoming applications, include the 
'virtuphone -- a telephone that you wear'.
Thomas A. Furness is a Professor of Industrial Engineering at the 
University of Washington in Seattle and founding director of the 
Human Interface Technology Laboratory at the Washington Technology 
Center.  He was Chief of the Visual Display Systems Branch, Human 
Engineering Division of the Armstrng Aerospace Medical Research 
Laboratory (USAF), Wright-Patterson AFB, Ohio.  Beginning in 1966, 
Dr. Furness developed and evaluated visually-coupled systems and 
virtual interface concepts to improve the communication of 
information and control functions between the pilot and advanced

  James Martin, Author/Consultant
     Enterprise Visualization and Object-Oriented Modeling
It is becoming increasingly important to redesign corporations and 
business processes.  We need to represent the activities of 
corporations in ways which are meaningful to the businesspeople.  
The stream of processes can be thought of in terms of objects and 
activities which change those objects.  With an object-oriented 
model we can visualize the value streams in ways which enable us 
to redesign them.  We need to explore the best forms of enterprise

addition to receiving a Pulitzer Prize nomination for 'The Wired 
Society,' and penning the 1984 top-selling book on computers, 'An 
Information Systems Manifesto,'  Dr. Martin's works are 
authoritative sources on application development, data base, 
teleprocessing, telecommunications, interactive systems, and the
