Workshop: 5. Designing User Interfaces for Safety Critical Systems
Phillipe Palanque, University Toulouse 1; Fabio Paterno, CNUCE-CNR; Peter Wright, University of York

When designing user interfaces for safety critical systems designers must satisfy both usability and safety requirements at both the specification and implementation level. These systems have human operators and increasingly their role is mediated by computer technology. Clearly, in this domain, usability issues can have potentially disastrous consequences, yet CHI conferences have not addressed this type of application. We believe that the design of user interfaces in this area requires the use of innovative technologies for supporting user interactions and the support of many kinds of skills and backgrounds to be addressed effectively.

The challenge of the workshop is to bring together researchers from the disciplines of software engineering and human factors to consider issues in safety critical system design which are at the intersection of usability and safety. Areas of concern are requirements analysis, specification, testing and evaluation.

We will focus on specific issues which we feel are relevant in this application area:

Workshop: 6. From Task to Dialogue: Task-Based User Interface Design
Birgit Bomsdorf, University of Paderborn; Gerd Szwillus, University of Paderborn

It is generally accepted that the tasks the user has to fulfill with a system should play an important role in its design. Knowing the user's tasks enables the designer to construct user interfaces reflecting the tasks' properties, including efficient usage patterns, easy-to-use interaction sequences and powerful assistance features. As a consequence, task modeling becomes a central part of the user interface design process. To accomplish this, a systematic transition has to exist from task identification to user interface construction. Hence, a task model of how the user performs her or his tasks with the system has to be defined. This model contains the task structure, the division of labor between user and system as well as information about the objects used within tasks. The result of this design phase is a dialogue model: a constructive abstraction of the finally implemented user interface.

The goal of our workshop is to learn more about the transition from task model to dialogue model. We will bring together people with expertise in this domain in order to collect, structure and interrelate work dealing with this non-trivial transition. We will discuss practical design projects where this problem showed up, research on theoretical, systematic approaches to the problem and development of tools and techniques supporting the transition.

The workshop is directed at people from academia, research departments of companies or software development companies dealing with practical user interface design problems. All participants should be actively interested in task and dialogue modeling and in the transition from one model to the other.

Workshop: 7. Hyped-Media to Hyper-Media: Toward Theoretical Foundations of Design, Use and Evaluation
N. Hari Narayanan, Auburn University

The rate of creation of hypermedia information has far outpaced developments in the theory of how to design hypermedia to best facilitate users' comprehension of, and navigation within, the information being presented. Despite (or perhaps, because of) the commercial success of these systems, their design had largely been guided by common sense and intuitions rather than theory. In this context, the theme of the workshop is emerging theoretical foundations of design, use and evaluation of interactive visualization, multimedia and hypermedia systems.

Topics Include

Two kinds of electronic submissions (HTML files) are solicited:

Invitations to participate will be issued based on a review of submissions. We will be looking for innovative theories, integrative approaches, promising works in progress and the potential to stimulate discussion. We expect to invite no more than 20 participants.

Workshop: 1. Basic Research Symposium
Joseph Konstan, University of Minnesota; Jane Siegel, Carnegie Mellon University

The CHI Basic Research Symposium presents an opportunity for researchers from different disciplines to exchange new developments and insights from their own fields and thereby expand their vision of human-computer interaction. The two-day event is a cross between a mini-conference and a workshop. Participants are selected by a program committee that reviews submitted position papers, bringing together a diverse group of researchers with innovative research underway. The symposium itself includes interactive research presentations, group discussions around common themes and small, group break-out activities.

The mission of the CHI Basic Research Symposium is to provide a venue where researchers conducting ground-breaking, controversial and emerging research can discuss that research with a diverse group of peers. Our vision for this year's Basic Re-search Symposium is for each participant to leave with a better understanding of the re-search methods, goals and frontiers of a wide range of HCI disciplines. Each participant should contribute to the collective under-standing and leave with new ideas for conducting, integrating and applying research.

The Basic Research Symposium welcomes two types of submissions:

(1) Position Papers. Up to ten pages introducing your field and your work. Authors of accepted position papers will be given time to present the work in an interactive discussion format.

(2) Position Statements. Up to two pages introducing you and your interests. Authors of accepted position statements will be invited to participate in the symposium.

Sample submissions and further information is available at http://www.cs.umn.edu/~konstan/BRS98/.

Workshop: 2. Innovation and Evaluation in Information Exploration Interfaces
Gene Golovchinsky, FX Palo Alto Laboratory; Nick Belkin, Rutgers University

Traditional Information Retrieval (IR) is concerned with improving effectiveness of indexing and retrieval mechanisms, and with supporting one information seeking behavior: specified searching through query formulation. This supports one kind of user population, with one kind of information need. The networked information environment has resulted in a shift in the user population of IR systems. This has introduced new classes of users, in the sense of levels of expertise, and has also made clear that there are different kinds of information needs and different kinds of information seeking behaviors than those supported by traditional IR systems and techniques. This workshop focuses on developing an understanding of one such information seeking behavior, Information Exploration, on interface design for supporting this behavior and on evaluation methods for assessing such interfaces. Information Exploration addresses the goal of refining a vague concept into a more thorough understanding of the problem that led to the information interaction.

Problems to be addressed include:

Twenty participants will be selected on the basis of a one-page abstract of a position paper on one of the three themes of the workshop. These abstracts must include a specification of the Information Exploration task which is being addressed and an explicit statement of the relationship of the proposal/position to that task.

Workshop: 3. Incorporating Work, Process and Task Analysis into Industrial Object-Oriented Systems Design
John Artim, OOCL; Mark van Harmelen, Cutting Edge

Discussion at last year's workshop, "Object-Oriented Models in User Interface Design," examined the role of object modeling in user interface design. Workshop participants collaborated on a framework describing user interface design in the software development life cycle. This framework is described in the October 1997 issue of SIGCHI Bulletin. We take as a starting point this framework. The goal of this workshop is to produce a method and notation framework to support the use of task, process and work analysis and modeling as a source of objects for system design and a determinant for suitable end user support by the system.

Potential participants should submit a position paper of approximately 2000 words that describes experience or theory relating to:

Papers should, where appropriate, build upon last year's workshop discussion as expressed in the SIGCHI Bulletin article.

Workshop: 4. Innovative Interface Metaphors for Visual Media
Arnd Steinmetz, GMD-IPSI; Frank Nack, GMD-IPSI; Nahum Gershon, MITRE

The fundamental problem associated with video and images is that they are already visual data. Thus, many interesting classes of visual information have no natural and obvious alternative presentation despite their original appearance. The arising problem is, therefore, to visualize a more metaphorical view onto that information which does not automatically map onto the physical world.

In spite of this need, current visualization research (e.g., Videostreamer (Davenport) or Video Micons and Video Space Icon (Tonomura/Abe)) has not been active enough in discovering new visual metaphors for representing/presenting pictorial information.

The purpose of the workshop is to explore new ideas for representations of visual media and to clarify the nature, scope, limits and dangers of new interface metaphors for visual media.

Applicants should send position papers (3-5 pages in .pdf format), articulating their interests, ideas and experiences in information visualization and visual media. Videos and application demonstrations are strongly encouraged. We welcome papers from people with a variety of insights and perspectives (e.g., HCI, data mining, imaging, graphics, entertainment, education, etc.). Selection, based on the position papers, will seek to balance perspective and interests of the participants.

Participants will be expected to read the position papers of other participants prior to the workshop, and to prepare a brief presentation of their own views. Participants will be asked to assist in the preparation of the workshop report. The workshop is limited to 15 participants.

Workshop: 12. Beyond Internet Business-as-Usual
Markus Stolze, IBM Zurich; Patrick Steiger, IBM Zurich; Michael Good, SAP Technology

The increasing success and popularity of Internet commerce makes it important to step beyond current limitations to overcome the problems shop designers are struggling with today, to better exploit the opportunities of electronic media and to prepare for new types of products and services. The goal of the workshop is to better understand the current state of Internet commerce and to generate a road map and research agenda for moving beyond Internet business-as-usual. Towards this end we want designers to report their practical experiences with setting up, running, maintaining and improving electronic shops. We want researchers to present prototypes, technologies and frameworks that show ways to transcend the current state of the art in Internet commerce and to accommodate growing user needs. Moreover, we want research and experience reports on how Internet commerce is changing the social fabric of business as well as the nature of individual transactions.

If you are interested in the workshop, submit a one-page statement of your background and pertinent interests, together with one recent paper (or description of an implemented system, including URL and/or other screen shots) related to the workshop topic.

Workshop: 13. Learner-Centered Design: Addressing, Finally, the Unique Needs of Learners
Sherry Hsi, UC Berkeley; Elliot Soloway, University of Michigan

Ease of use, valuable as it certainly is, is too limited a vision. We need to raise our expectations for what computationally-based interfaces can support and address the challenge of nurturing the intellectual growth of children and adults. Simply put, we need to move from focusing just on the needs of users to focusing on the needs of learners (i.e., growth, diversity, motivation).

A new generation of researchers cross-trained in education, engineering, design, cognitive science and computer science, are taking the design process into schools, homes and workplaces. This new generation's design practices combine academic research, technology design, and assessment in authentic classroom context to formulate emerging practices, new design methods and principles. The goal of these folks is to design software that "make people more effective learners" while also designing interfaces that make them want to learn and know how to learn beyond the computer task at hand. We wish to take the opportunity of CHI 98, with its theme of education, to hold the first formal meeting of those interested in Learner-Centered Design (LCD).

If you are interested in participating, please send a one-page description of your current efforts in addressing the needs of learners, plus a one-paragraph statement about what you hope to get out of such a one-day workshop. The program committee will then review all submissions and select 20 participants. Send statements to Elliot Soloway, soloway@umich.edu and Sherry Hsi, hsi@socrates.berkeley.edu.

Workshop: 14. Trust and Accountability: Preserving Human Values in Interactional Experience
Batya Friedman, Colby College; Jonathan Grudin, UC Irvine

The common good of our information infrastructure depends on designs through which users can establish and maintain trust and accountability. Consider, for example, current questions in the design of Internet commerce. Should we provide simple statements of security? Should we provide technical descriptions of security technology (e.g., encryption algorithms)? Or, following the UL approval seal for electric light bulbs and appliances, should we evolve a set of standards and conventional notations for establishing levels of trust and channels for accountability? Or all of the above and more?

In this workshop we are concerned with understanding how to design computer-based interactional experiences that preserve trust and accountability. We draw on the organizers' background and participants' research and design experiences to: (1) identify positive designs and abuses of trust and accountability in computer systems and (2) generate design principles for preserving trust and accountability in the design of future systems. Presumably successful designs will require multi-faceted innovations that include new technical mechanisms, interface metaphors and, on a societal level, the development of social conventions and standards.

Who should attend? Participants with diverse backgrounds and design experiences are desired, including designers, educators, practitioners and researchers. Interested individuals should submit a letter describing his or her (1) interest in the topic, (2) background and (3) three cases in which he or she has encountered issues of trust and/or accountability in a computer system, either as a designer or as a user. Each case should discuss the context of use, the design and the issue that arose.

Workshop: 15. User Interfaces for Computer-Based Patient Records
Tom Brinck, Diamond Bullet Design; Gary York, ComFrame Software

The patient record is a central artifact used throughout the health care setting, not only by physicians and nurses, but by numerous hospital staff from clinicians to housekeeping. In 1991, the Institute of Medicine produced a report called The Computer-Based Patient Record (CPR) that set down a vision for computerizing the wide variety of activities in documenting, reviewing and storing the patient record. Variations of CPR systems have been known by many names, including "electronic medical records" and "clinical information systems." CPRs offer the potential for substantially reduced healthcare costs and improved patient care, but many would attribute their slow adoption to the difficulty of designing user interfaces appropriate to the incredibly complex domain of health care.

The goals for the workshop are:

We invite participation from a wide range of professionals involved with the design, development, deployment and evaluation of the CPR to discuss user interface issues, identify roadblocks in designing effective user interfaces and set an agenda for the future of user interface issues in the design of CPRs.

Up to date information on the workshop will be available at http://www.diamondbullet.com/cpr/.
