*IBM TJ Watson Research Center, Hawthorne, NY USA 10532
+Helsinki Institute for Information Technology, P.O.Box 9800, FIN-02015 HUT, Finland

This two-day workshop will focus on the HCI issues related to interactive communication in personalized user experiences in eCommerce. The workshop will form a community to access the current state of theory, methods, and research in this area and to create a theoretical framework to help identify critical questions and guide future research. The first day will include presentations and discussions on topic clusters in personalized user experiences in eCommerce identified in participant position papers. Participants will discuss the patterns, or lack thereof, in the results, potential components of a personalization framework, gaps in knowledge, and research questions. During Day 2, workshop participants will engage in three consecutive focused discussions on theory, methods, and research questions and hypotheses to determine if a framework of personalized eCommerce user experiences can be created that encompasses the variety of issues and variables identified in Day 1.

We welcome participants from industry, academia, and government. We encourage people who are designing personalization features for eCommerce web sites, those approaching this issue from a more theoretical vantage point, and individuals representing governmental bodies who are enacting policies to protect the privacy of users or customers who provide personal data. Potential attendees need to submit a 2-5 page position statement to the organizers ( by January 17, 2003. The outcome of the workshop will be published as a book or a special issue of a journal. Each attendee will contribute to the publication by authoring or co-authoring a chapter or a paper.

Workshop 02 (Sun./Mon.)

Designing for Learning

Susanne Jul
Chris Quintana
University of Michigan

Learning is essential to life as we know it. The rate of social and technological change has increased to a point where an individual must constantly acquire new skills and knowledge in order to maintain their place in society. It is imperative that the complex technological tools that drive this change also help users acquire new knowledge and skills. This two-day workshop is aimed at developing a conceptual framework for the design of user interfaces that promote learning, focusing on learning as a problem in design rather than a problem in psychology or education. The 16 workshop participants will be selected with a view to creating a diversity of perspectives and backgrounds to ensure that a broad spectrum of learning and design issues are considered. The workshop is organized around a friendly design competition aimed at providing a tangible context for discovering and discussing theoretical as well as applied issues. Design mockups or prototypes resulting from this competition will be presented for review by CHI attendees at the CHI poster sessions.

16 participants will be selected on the basis of a 2500 word position paper. Priority will be given to individuals demonstrating a strong commitment to work in the topic area. Position papers should describe the applicant's understanding of the topic, current work or plans for work in the topic area and include a brief description of the intellectual background of the applicant (e.g., intellectual, cultural or subcultural influences). Position papers must be submitted electronically (preferably as URL's) to by January 17, 2003.

Workshop 03 (Sun./Mon.)

Perspectives on HCI patterns: concepts and tools

Organizers: Sally Fincher (University of Kent), Janet Finlay (Leeds Metropolitan University), Sharon Greene (IBM Research), Lauretta Jones (IBM Research), Paul Matchen (IBM Research), Pedro Molina (CARE Technologies and the Technical University of Valencia), and John Thomas (IBM Research).

This workshop aims to map current understanding and use of HCI Patterns and determine how to make significant advances through two perspectives: 1) a view of the conceptual foundations of patterns and their relationship to other HCI models and approaches 2) a focus on tools and methodologies related to pattern creation and use.

Discussions will consider why/how patterns are identified and when/how they are useful in design and development. Relevant issues here include levels of abstraction and complexity; the nature of invariance; pattern evolution; representations, process and use. Through hands-on experience using pattern tools, and observation of and reflection on such usage, we will build a common understanding of what is needed for useful pattern tools.

We anticipate discussions will enrich and help frame the hands-on tool experiences and, conversely, the tool-use exercises will ground and sharpen discussions.

Participants should send a two to four page position paper that states either: 1) their position on the conceptual issues of importance in HCI patterns or 2) experiences with, requirements for, or designs of tools to support the creation, organization, and use of patterns. Participants will be selected on interest, commitment, and current work; and to provide a balance between the two perspectives.

Please send position papers both to and by January 17th, 2003.

Workshop 04 (Sun.)

Scenarios in Practice

John Carroll (Virginia Tech),
Mary Beth Rosson (Virginia Tech),
Paul McInerney (IBM)

This one-day workshop examines using scenarios effectively and efficiently in industrial projects. This includes lessons learned and remaining challenges. The scope includes the following overlapping topics: (1) Deployment, i.e., how to manage a large-scale scenario-based effort in an industrial project. (2) Method integration, i.e., when and how to use scenarios in conjunction with other methods such as hierarchical task analysis, use cases; integrating scenarios with other project activities such as setting ease-of-use objectives and writing documentation. (3) Craft and quality, i.e., tips for scenario writing, analyzing scenarios, and formatting scenarios. (4) Project contexts, i.e., writing scenarios for innovative new projects vs. the follow-on release of a mature product; writing scenarios for various types of products.

Participants will be selected based on their experience (1) writing scenarios and (2) deploying a scenario-based approach in industrial contexts.

People interested in participating are invited to submit a 2-3 page position paper that includes the following sections.

  1. Background: State the number of scenarios you've written and provide some background on the projects in which they were written. Describe how scenarios are related to your current project responsibilities or research interests. Identify related publications or other professional activities, if any.

  2. Position(s): Describe your position (i.e., experience, views) on at least one of the topics listed above. Optionally, also discuss topics related to scenarios not directly mentioned above.

Workshop 05 (Sun.)

End User Development

Henry Lieberman, MIT MediaLab, Cambridge, USA
Fabio Paterno, ISTI-C.N.R., Italy
Alexander Repenning, University of Colorado, USA
Volker Wulf, University of Siegen and Fraunhofer FIT

The wide-spread penetration of interactive software systems has raised an increasing need for better environments for building applications. The interactive richness of new devices has created the potential to overcome the traditional separation between end users and software developers. New environments able to seamlessly move between using and programming (or customizing) can be designed. Advanced techniques for developing applications can be used by individuals as well as by groups or social communities or organizations. There are studies that indicate that the end-user programming population will be growing at more than 10 percent per year worldwide.

The goal of the workshop is to bring about a coherent research agenda in the field of end user development. We seek contributors concerned with: adaptability, adaptivity, tailoring of system functionality and user interfaces, the use of annotations for individuals and user groups, and use of effective visual and multimedia representations.

Topics of interests include:

  • end user development architectures
  • innovative scripting languages
  • web-programming
  • adaptive and situation aware applications
  • interfaces for end user programming
  • collaborative programming/tailoring activities
  • design principles for end user environment
  • psychology of end user programming
  • heuristic evaluations of end user programming environments
  • ethnographical studies on end user programming


Send position papers (up to 4 pages, deadline January 17, 2003) and questions to Fabio Paterno

Workshop 06 (Sun.)

Humor Modeling in the Interface

Anton Nijholt (University of Twente, The Netherlands)
Oliviero Stock (ITC-IRST, Italy), Alan Dix (Lancaster
University, United Kingdom), John Morkes, (Trilogy, USA )

In future human- machine interaction, humans will demand a naturalness and effectiveness that also requires the incorporation of models of possibly all human cognitive capabilities, including the handling of humor. In daily-life interactions humor does not only play an entertaining role. It helps in regulating conversations (social and business conversations), building trust between partners, facilitating self-disclosure and it is an important factor in social attraction. Teachers know how to smooth tension by using humor and negotiators employ humor in the different phases of a negotiation. Computers can be considered as social actors and they can take the role of one of the partners in human-human communication and from experiments it can be expected that they can effectively employ humor in their interaction with human partners.

Moreover, in many situations, not only in specially designed entertainment environments, we may assume that human-computer interaction will be less goal-directed than it has been in the past. Information and communication technology is moving to the living room and all sorts of social environments where we have human-(embodied) agent interaction and computer-mediated interaction where computers can become (semi-autonomous) partners in the human-humans interaction. As more researchers get involved in these topics it becomes clear that our current understanding of user concerns is too much derived from the world of work and efficiency and it should be complemented with understanding of social partner concerns, including the different roles of humor.

This workshop aims to:

  • To provide a forum to discuss the role of humor in human-computer interaction;
  • To discuss a research agenda, including the identification of relevant (computational) humor theories and relevant applications;
  • To identify recommendations as to how companies and research funders can combine and use the several disciplinary specialties needed to design interfaces that employ humor

We encourage participation from a wide range of disciplines including Human-Computer Interaction, Computer Science, Computational Linguistics, Artificial Intelligence, Psychology and Social Science.

We plan to cover the following general topics: humor in human-human communication, humor in human-computer interaction, (computational) humor theory, conversation violation, user modeling and senses of humor, and applications ranging from electronic commerce and educational environments to entertainment and smart home environments.

The workshop format will include a presentation by each participant and discussion. In addition each participant will lead a discussion on the issues raised by another participant's paper.

The workshop will be limited to 16 participants. Please submit a 2-4-page position paper outlining your interest in this topic to Position papers must be received by 17 January 2003. Participants will be notified of selection by 7 February 2003.

Workshop 08 (Sun.)

Best Practices and Future Visions for Search User Interfaces: A Workshop

Misha W. Vaughan (Oracle Corporation),
Helmut Degen (SiemensAG Germany),
Marc Resnick (Florida International University),
Peter Gremett (AOL Time Warner)

Search activities (e.g., searching for information about a topic, documents, or a location) are among the most important activities on the computer and the Internet. At the same time, we have yet to arrive at usable design solutions for search user interfaces. Sophisticated users often have difficulty navigating through the complexity of search engine interfaces and the typical Web user is severely challenged. Because of new application areas (e.g. ebusiness, mbusiness) and increasing use of additional devices for search (e.g. desktop, laptop, mobile devices) new questions are arising concerning the design of user interfaces for searching.

This one-day workshop will create a roadmap of current best practices and future needs for search user interface design. It will provide an interactive forum for participants to actively discuss submitted papers, industry trends, and gaps in our knowledge. Participants will come away with new research findings, key contacts, and identified opportunities for research. Participants from industry and academy are invited to participate. By including both groups, we intend to balance the discussion between theory and application.

This search workshop covers the following topics:

  • User psychology and behavior
  • Usability engineering methods for search
  • Input, output, and iterative search
  • Application areas: ebusiness, ecommerce, intranets, web content
  • Search devices: desktop search, mobile search, cross-platform search, web-based search
  • Search scenarios of use
  • Intercultural search: Search in Asia, Europe, Americas, Africa, Australia

The results of this workshop will be published in the SIGCHI Bulletin. Follow up workshops will be considered to work through specific topics in more detail.

Potential participants are invited to submit a 2-page extended abstract to Misha Vaughan ( by January 17, 2003, related to one of the topics listed above. Along with the extended abstract we would like participants to attach a short biography indicating their experience and expertise, particularly as it relates to search user interfaces.

Workshop 09 (Sun.)

Workshop: Supporting Intercultural Computer-Mediated Discourse: Methods, Models, and Architectures

Fahri Yetim (New Jersey Institute of Technology),
Elaine Raybourn (Sandia National Laboratories)

We use the phrase intercultural instead of cultural to emphasis the dialogical relationship of at least two participants from different cultures in computer-mediated communication and cooperation contexts. Supporting intercultural computer-mediated communication (I-CMC) requires, on the one hand, the understanding of both enabling and constraining aspects (barriers) of such a dialogical situations, and calls, on the other hand, for new ideas for tools, architectures, etc., which may support, promote or enable computer-mediated intercultural communication and cooperation.

This workshop explores the challenges in the intercultural computer-mediated communication and cooperation environments and will provide a platform for discussing empirical insights into the intercultural communication barriers and practical and theoretical works for new designs, tools and architectures that aim at overcoming them and enabling computer-mediated intercultural communication and cooperation.

Participants will be selected based on their position papers. We also aim to balance the workshop in terms of position on the analysis-design spectrum.

Workshop 10 (Sun.)

HCI and Security Systems

Andrew Patrick (National Research Council of Canada),
A Chris Long (Carnegie Mellon University),
Scott Flinn (National Research Council of Canada)

The human factor is often described as the weakest part of a security system and users are often described as the weakest link in the security chain. This workshop will seek to understand the roles and demands placed on users of security systems, and explore design solutions that can assist in making security systems usable and effective. In addition to examining end-users, this workshop will also examine the issues faced by security system developers and operators. The primary motivation for the workshop is that previous research on HCI and Security (HCISEC) has been scattered in different conferences and journals, and information sharing has been difficult. The goal of the workshop is to build a network of interested people, share research activities and results, discuss high priority areas for research and development, and explore opportunities for collaboration.

Security is a large topic so there are many areas where HCI is important. Three obvious areas of interest are authentication (passwords, biometrics, etc.), security operations (intrusion detection, vigilance, policies and practices, etc.), and developing secure systems (developing for security, understanding users, installation and operation support, etc.). We are interested in receiving submissions on these topics, and suggestions of other possible topic areas are also welcome.

Contributions should be in the CHI 2003 Extended Abstracts style, 2 to 4 pages long. Participants will be selected based on the contribution to the goals of the workshop, the shared interests of the other participants, and likelihood to promote discussion and collaboration.

Please send inquiries and submissions to Andrew Patrick,

Workshop 11 (Mon.)

Principles for Multimodal User Interface Design

Jim A. Larson, Intel Corporation,
Sharon Oviatt, Oregon Graduate School, Oregon Health and Sciences University

Multimodal user interface design principles are rules that may apply to some subset or all multimodal interfaces residing on a variety of devices, ranging from cell phones with speech and keypad or stylus input, to PCs with keyboard, speech, stylus or other input modes, or to virtual-world devices with speech, haptic/manual, and other means of input. While guidelines often serve as a checklist of what to do and what not to do in a user interface, guiding principles that motivate and encourage good dialogue designs are based on predictive user data and models and they explain "why" as well as than "what" and "how to" about interface design practices. For example, the principle of dialogue symmetry suggests that users' respond to a multimedia response with multimodal input that is similar in mode, style, linguistic features and phrasing as those used in the prompt.

The goal of this workshop is to identify and publish ten major principles for promoting the good design of multimodal user interfaces.

Individuals interested in participating in this one-day workshop should e-mail a 2-3 page position paper to by Jan. 17, 2003. The position paper should contain:

  • Your name, affiliation, and contact information
  • Short bio with description of research or design experience relevant to workshop
  • Initial description of five principles for designing multimodal user interfaces

Participants will be selected based on their workshop position paper and the relevance of their background. (We want diverse backgrounds so that the principles apply to various types of multimodal user interface.) The organizers will integrate guidelines from selected position papers, distribute them to attendees prior to the workshop, and then summarize them as a post-workshop publication.

Workshop 12 (Mon.)

Comparative Expert Reviews

Rolf Molich (DialogDesign, Denmark),
Robin Jeffries (Sun Microsystems)

Are you a usability professional who is doing expert evaluations, heuristic inspections or usability testing? Have you ever humbly considered whether you are applying these methods in accordance with the state-of-the-art in the area? Do you want to compare yourself to some of the experts in the area and learn from them? Do you want to contribute to the further development of these methods?

If you answered yes to two or more of the above questions, chances are that you will find this workshop interesting.

In this workshop we will try to obtain a better understanding of the strengths and weaknesses of the expert review and heuristic inspection methods. We will do this by comparing results of independent expert reviews, heuristic inspections and usability tests of the same state-of-the-art website carried out by the participating expert usability professionals. You must carry out an evaluation of a website ahead of the workshop. The evaluation can either be an expert review, a heuristic inspection or a usability test with at least five users. The website will be selected by the organizers.

Workshop 14 (Mon.)

Designing Culturally Situated Technologies For The Home

Genevieve Bell (Intel),
Mark Blythe (York University),
Bill Gaver (RCA),
Phoebe Sengers (Cornell University),
Peter Wright (York University)

Through the ownership and use of particular technologies and artifacts we make statements about our selves, our values and our culture. Nowhere is this clearer than in the home, which is widely recognized as a complex and diverse design environment. Critical readings of the social context of use and the codification of meaning can generate innovative approaches to design problems. This workshop will consider how designers do, can, or should integrate cultural analysis in their technologies

Issues of interest include:

  • Design techniques that use cultural and social analysis to inform the design of new home based digital products.
  • Analytical techniques for studying the cultural and political assumptions that are embodied in current domestic technology.
  • Methods and techniques for designing across cultural boundaries.

We plan to cover the following general topics: theory, drawn from various disciplines; field studies and experiments; practice, through case studies of products and experimental designs; technique, and the design process. The workshop format will include a presentation by each participant. In addition each participant will lead a discussion of the issues raised by another participant's paper. We encourage participation from a wide range of disciplines including Computer Science, Product Design, Psychology, Social Sciences, Literary and Cultural Studies.

Please submit a one- or two-page position paper (as a Word or PDF file) outlining your interest in this topic to Position papers must be received by 17th January 2003. Participants will be notified of selection by 7th February 2003.

Workshop 15 (Mon.)

Subtle Expressivity for Characters and Robots

Noriko Suzuki (ATR, Japan),
Christoph Bartneck (Technical University of Eindhoven, The Netherlands)

Humans, both consciously and unconsciously, use subtle expressions to communicate their emotions and intentions through variations of the gaze direction, pitch of speech and gesture speed. They form their own class of communication acts. Embodied characters, including robots, need to use subtle expressions to become believable communication partners.

The design and evaluation of subtle expressivity are challenges for designers and researchers of embodied characters. How do the subtle variations in expression influence the interaction? What types of subtle expressions are most important for the design of interactive media? How can the effect of the expressions be reliably measured?

The workshop aims to:

  • Provide a forum to discuss emerging issues in the design and evaluation of subtle expressivities and its applications.
  • Discuss the role of cognitive science and psychology in the use of subtle expressions in the design of interactive media.

We plan to cover the following topics:

  • Concepts, theories or guidelines for design of subtle expressions
  • Implementation methods for of subtle expressions
  • Measuring methods for the effects of subtle expressions.


The workshop will consist of a daylong highly interactive format that will encourage open dialogue and sharing wisdom. We will aim to achieve a balance of viewpoints and backgrounds in the selection of participants.

Workshop 16 (Mon.)

Providing Elegant Peripheral Awareness

JJ Cadiz (Microsoft Research),
Mary Czerwinski (Microsoft Research),
Scott McCrickard (Virginia Tech),
John Stasko, (Georgia Inst. of Technology)

This one-day workshop will strive to build community among the researchers in the emerging area of peripheral awareness interfaces. The workshop will begin with demonstrations of systems designed by the participants. Activities will then switch to small groups discussions on a variety of issues, including the common challenges facing peripheral awareness interfaces and aspects of a peripheral awareness research taxonomy. Workshop participants will also spend time creating a research framework for approaching peripheral awareness. This framework will be developed by exploring key features of peripheral awareness interfaces, key design themes within the peripheral awareness design space, and evaluation procedures that can be used to measure the usability and utility of these types of interfaces.

Participants from a wide variety of fields are welcome (information visualization, cognitive psychology, tool developers, etc.). Interested participants should send position papers to JJ Cadiz (

Workshop 17 (Mon.)

System Administrators are Users, Too: Designing Workspaces for Managing Internet-Scale Systems

Rob Barrett, IBM Almaden Research Center, USA
Yen-Yang Michael Chen, University of California at Berkeley, USA
Paul P. Maglio, IBM Almaden Research Center, USA

The people who run large-scale computer systems deserve the attention of the HCI community. These professionals work with increasingly diverse and complex hardware and software, large systems often characterized as "unknowable" by a single person. Relying on relatively crude tools, these professionals keep the technological world running. By improving the system administration work environment, the cost of computing and risk of downtime will be decreased while the deployment of complex, beneficial systems will increase.

This one-day workshop will focus on the HCI problems of system administrators, specifically management of scale and diversity, problem solving, and system monitoring and notification. Our goal is to bring together (1) HCI researchers, (2) middleware user interface software developers, and (3) real-world system administrators to form a cross-disciplinary community around this topic. Participants from the three groups will share their different perspectives through panel discussions on assigned topics. Participants will also prepare and share three-minute VHS videotapes of some real-world system administration activity. The final session will be a joint design activity, with the goal of beginning work on a cross-disciplinary paper that will form the foundation for a special issue of a relevant journal.

Participants will be selected on the basis of three-page position papers that describe and analyze a particular system administration problem or activity. A brief biography noting the reasons for interest should be appended. Participants will be selected with equal representation from each of researchers, developers, and administrators.

Send position papers or questions to Rob Barrett:
