USER INTERFACE STRATEGIES '94 A Live Satellite TV Broadcast December 14, 1993, Tuesday 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, science, entertainment, 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 and on the National Technological University (NTU) Network. Contact your organization's training office to ask if they can arrange a satellite downlink.

Next Generation Graphical User Interfaces Ben Shneiderman, University of Maryland The wildly popular graphical user interfaces (GUIs) are an improvement over command languages, but the next generation of user interfaces is already on the way. The aging GUIs with clumsy one-window-at-a-time housekeeping will give way to rapid, coordinated multiple windows. The future will be dynamic, spatial, 3-dimensional, virtual, ubiquitous, gestural, colorful, often auditory, and sometimes immersive. The demand for high resolution multimedia and full-motion video will push the hardware requirements, absorb network capacity, and challenge the algorithm designers. How can we balance the desire for innovation with the need for stability? Ben Shneiderman is Head of the Human-Computer Interaction Laboratory, Professor of Computer Science, and Member of the Institute for Systems Research all at the University of Maryland, College Park. He is the author of Designing the User Interface, 2nd Edition and Software Psychology, and the co-author of the hyperbook/disk Hypertext Hands-On!. Dr. Shneiderman is the editor of Sparks of Innovation in Human-Computer Interaction, on the editorial board of 6 journals, the author of 150 technical papers, and the creator of the Hyperties hypertext system. His consultancies have included Apple, AT&T, GE, IBM, Intel, Library of Congress, NASA, and NEC. Usability Engineering Jakob Nielsen, Bellcore Usability engineering is the systematic approach to improving user interfaces by applying a set of established methods throughout the system development lifecycle. There is a large number of methods to choose from, but this presentation will focus on a small number of highly cost-effective methods that can be used by all development projects. Methods to be covered include heuristic evaluation for "quick-and-dirty" finding of usability problems at minimal cost, thinking aloud and user testing for empirical verification of usability. Across a number of projects, iterative design to remove usability problems has been found to improve measured usability by 38% per iteration as the median value. Jakob Nielsen is a member of the Computer Sciences Department in Bellcore's applied research area. Dr. Nielsen's earlier affiliations include the IBM User Interface Institute in Yorktown Heights, NY and the Technical University of Denmark. Nielsen coined the term "discount usability engineering" and was the co- inventor of the heuristic evaluation method. He is the author of the books Usability Engineering and Hypertext and Hypermedia, and on the editorial boards of five journals in the user interface and hypertext fields. Nielsen also was the papers co-chair for the joint ACM and IFIP INTERCHI'93 international conference on computer-human interaction. Groupware: Supporting Group Work with Technology Judy Olson, University of Michigan Most of the work we do in organizations is done as members of groups or teams. A set of software applications is emerging that is specifically built to support work groups. These include email, conferencing systems that support structured discussions among people working at different times and places, meeting rooms with linked computers and decision support software, video conferencing in meeting rooms, desktop video connections for both informal and intense encounters, and remotely linked computers for distant, real-time work. To capitalize on the benefits of this new groupware technology and avoid the pitfalls, we have to understand more about how it changes the quality of work, social interactions, and organizational processes. Judith Olson is Professor and Chair of the Computer and Information Systems Department at the Michigan Business School. She is a senior researcher in the Cognitive Science and Machine Intelligence Laboratory, where she conducts research on the behavior of groups in both face-to-face meetings with technology support, and in remote offices connected with computers and video. She has done research on user interface design and was a Technical Supervisor of human factors in systems engineering at Bell Laboratories. Prof. Olson is on the General Council of the ACM, active in the CHI conferences, on a number of editorial boards, and a consultant at major companies in the US (e.g., IBM, GM, EDS, Unisys) and Europe (e.g., Netherlands PTT, Rank/Xerox). Virtual Reality: Where Users Become Participants Myron Krueger, Artificial Reality Corp. Virtual reality is the most widely touted technology in memory. At the same time, there is reason to doubt that many people are going to be willing to wear scuba gear in the office. However, the idea of virtual reality works, even if the current technology does not. It changes how we think about the human interface and suggests new application domains as well as novel approaches to familiar problems. This talk will describe an unencumbering technology that can be used in the near term and a novel head- mounted display that will be acceptable for everyday use. Dr. Krueger pioneered the development of unencumbered full-body participation in computer-generated experiences. His VIDEOPLACE and VIDEODESK systems redefined telecommunication by placing remote participants in a shared graphic world in which they could interact naturally. His books Artificial Reality and Artificial Reality II (Addison-Wesley 1983 and 1991) were the first on virtual reality. He has received awards in both art and science, has given well over a hundred invited talks, and has been widely covered in the media.
