Other Activity: CHIkids and childcare

(Also available Monday, Tuesday, Wednesday, and Thursday)

There are two options: the traditional child care option and CHIkids. CHIkids is a place where kids, adults, and technology come together with common goals and do meaningful things.

The philosophy of the CHIkids program is built around the belief that technology is a tool to learning. CHIkids is about what can happen when technology is a catalyst. With the tools of technology, children can be conference reporters, web designers, multimedia storytellers, software testers, conference attendees, and more!

The innovative CHIkids program has been expanded for CHI 99. CHIkids combines the feeling of summer camp with the fun of technology, all as a part of the unique conference experience. This year's CHIkids program will provide kids with new extended opportunities for meaningful technology experiences.

• The traditional child care option offers children 6 months to 3 years, fun-filled, developmentally appropriate activities.
• CHIkids provides children 3 to 15 years of age with educational, purpose-driven technology experiences. Children ages 3 to 7 will use CD-ROMs, test new software, as well as be provided with a mixture of off-computer activities to complement their technology experiences. Children ages 8 to 15 will be provided with two main areas of exploration: creating multimedia stories in the Multimedia Storytelling area and being conference reporters using desktop publishing tools and the web in the CHIkids Newsroom.

All CHIkids activities will be led by a team of CHI volunteers with experience in technology, kids, and fun! Assistance will be provided by KiddieCorp, our experienced child care facilitators. Each day, children will be able to choose among various activities. The registration fee is US$75 per day, and includes lunch, snack, and CHIkids T-shirt. An optional field trip will be offered for CHIkids, 8 years or older, on Thursday, 20 May.

Workshop: 1. Basic Research Symposium

Yvonne Waern, Linkoping University, Sweden
John F. McGrew Pacific Telesis, Shared Services, USA

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. This 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 to bring 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 Research Symposium is for each participant to leave with a better understanding of the research methods, goals, and frontiers of a wider range of HCI disciplines. Each participant should contribute to the collective understanding and leave with new ideas for conducting, integrating, and applying research.

The BRS welcomes two types of submissions:

• Position Papers. Up to ten pages introducing your field and your work. Authors of accepted position papers will be given time to present their work in an interactive discussion format.
• Position statements. Up to two pages introducing you and your interests.

Workshop: 2. Interacting With Recommender Systems

Patrick Baudisch, GMD-IPSI, Germany
Loren Terveen, AT&T Research, USA

Recommender systems automate the process of passing experience from a community of users to an individual user who is about to make a decision. They support people in making recommendations and in finding a set of people who are likely to provide good recommendations for a given person.

This workshop will focus on user and usage aspects of recommender systems. The workshop will consider, among others, the following issues:

• for which domains and which communities of users are recommender systems appropriate?
• empirical evaluation of deployed systems
• can interest profiles be constructed automatically from implicit input?
• what types of incentives must be provided to motivate users to participate?
• how should recommender systems communicate their results to users?
• privacy aspects

Workshop: 3. Interacting in the Large: Developing a Framework for Integrating Models in HCI

Eamonn O'Neill, University of London, UK
Hilary Johnson, University of London, UK
Peter Johnson, University of London, UK

Modeling in early HCI concentrated largely on the individual user of a computer system. HCI has expanded its range of concerns to include the social, organizational, and environmental setting of interaction between possibly more than one user and more than one computer. The range of models used in HCI has correspondingly increased. The workshop objectives are to bring together researchers and practitioners in order to produce a shared understanding of what needs to be modeled and of the problems of integrating diverse models in interactive systems development; to provide suggestions of how to overcome those problems, and to undertake initial attempts at an integration of the models in an example domain. This example shall be provided by the workshop organizers in the form of a scenario of use in mobile computing. In the weeks before the workshop, the scenario will be circulated to the accepted participants.

Applicants should send position papers (2-4 pages) articulating the author's particular interest in the topic of the workshop; the author's background in modeling; an outline of a modeling approach with which the author has been associated either as a producer or as a user; and the author's experience with this approach. We envisage several papers coming out of the workshop which might comprise a special issue of a journal or an edited book.

Amy Bruckman, Georgia Institute of Technology, USA
Thomas Erickson, IBM, USA
Wendy Kellogg, IBM, USA
Lee Sproull, Boston University, USA
Barry Wellman, University of Toronto, Canada

Online communities are rapidly becoming a part of how we work, play, and learn. But how are they designed? What is already known in this emerging field? What are the key questions for future research? Research in this field is interdisciplinary, drawing on diverse fields including anthropology, architecture, computer science, human factors engineering, political science, psychology, and sociology. This workshop aims to bring people from these diverse fields together.

Those desiring to participate should submit a position paper:

• summarizing what your research has shown about online communities,
• outlining future directions your research will explore, and
• highlighting a few additional questions that you feel are important to the future of the field.

Papers must be submitted in HTML to asb@cc.gatech.edu. A length of less than 2500 words is suggested. Accepted papers will be posted on a workshop website. After the workshop, some participants will be invited to expand their papers into book chapters.

The primary criteria for acceptance are relevance to the topic and soundness of research methodology. Work of a speculative nature will not be included. We will also try to ensure that a variety of disciplines are represented.

Workshop: 5. Designing Electronic Books

Gene Golovchinsky, FX Palo Alto Laboratory, USA
Cathy Marshall, Xerox PARC, USA
Bill Schilit, FX Palo Alto Laboratory, USA

Science fiction introduced the idea of an electronic book; some early prototypes showed the potential of such devices; now we have the technology to implement these ideas. Still missing, however, is a principled look at features and interaction design that make electronic books usable. Getting the user interface right is critical. We would like to apply the expertise of the HCI community to understand the work practices e-books support, and to inform interaction and user interface design.

This workshop will bring together practitioners, researchers, and designers to explore the future of electronic books with an emphasis on HCI issues. About twenty participants will be selected based on two- to four-page position papers on HCI issues (practical or theoretical) related to e-books. Accepted participants will be expected to submit longer versions of their papers to provide more detail. Papers should address one or more of the following issues slated for discussion at the workshop:

How will e-books fit into existing practices, and how will they change them? Which activities will benefit from such devices, and which are better left on paper?

Do e-book features depend on the document genre? Which features are appropriate for which tasks? Can we identify design guidelines for electronic books?

Is the book an appropriate metaphor for an electronic book? Does familiarity with the book outweigh some of its limitations? Can we identify other appropriate metaphors?

Can we describe the relationship between the form factor of an e-book and its software interface?

Workshop: 6. Interacting with Statistics: Designing Interfaces to Statistical Databases

Michael D. Levi, US Bureau of Labor Statistics, USA
Frederick G. Conrad, US Bureau of Labor Statistics, USA

Suppose you move to a new neighborhood. You might want to know if you should worry about crime, whether the local schools are good, or whether the drinking water is clean. In each of these cases the relevant information exists in statistical data bases (SDBs). Whether a typical information seeker can find the information, however, is another question.

The purpose of this workshop is to foster the development of better, more usable interfaces to statistical databases: large, numeric data sets concerned primarily with social science. We will focus on the HCI problems that are peculiar to communicating requests for statistical information and presenting the results in a usable form. The outcome of the workshop will include a catalogue of HCI problems related to statistical information, a set of implemented solutions with accompanying commentary, and a set of research topics.

Workshop participants must have concrete experience developing or evaluating interfaces to statistical databases. Applicants should send a 3 - 5 page position paper headed with name and contact information and a one-paragraph biographical sketch. The paper should summarize the types of statistical data sets they work with, the type of usability problems their intended audience typically faces, and one or more useful interfaces they have either designed or evaluated which attempt to overcome these problems. If possible, please email the paper using ASCII, HTML, or Microsoft Word.

Workshop: 7. Tool Support for Task-Based User Interface Design

Birgit Bomsdorf, Universitaet GH Paderborn, Germany
Gerd Szwillus, Universitaet GH Paderborn, Germany

Task analysis and modeling are increasingly accepted as part of the user interface design process. This approach, referred to as task-based user interface design, must be supported by adequate tools, which stem from formal modeling or model-based approaches. The goal of this workshop is to learn more about these formal methods and the tool support needed when applying task-based user interface design in practice. We want to bring together researchers and practitioners to collect, structure, and interrelate work dealing with tools for task modeling, dialogue modeling, and the transition from task to dialogue modeling.

The workshop is intended for people from academia and research departments working, for instance, on model-based user interface design approaches or design environments, and for user interface designers in software development companies creating real designs in their everyday work practice. The workshop will be very interactive with most of the time used for discussion rather than presentations. Discussion will be encouraged by bringing together diverse groups such that different viewpoints can be developed and compared.

Participants will be selected based upon position papers addressing the following two discussion points:

• What formal methods and tool support do we need for task modeling, dialogue modeling, and the transition from task to dialog modeling?
• How is task modeling used in practice, what is its impact on the design process, and how can task modeling be further integrated into the design process?

David Novick, European Institute of Cognitive Sciences and Engineering, France
Ben Shneiderman, University of Maryland, USA
Michael Muller, Lotus Development Corporation, USA
Dan R. Olsen, Jr., Brigham Young University, USA
Cathleen Wharton, US WEST !NTERPRISE, USA

The goals of this workshop are to begin the development of an HCI research agenda statement, and to create plans for soliciting input from the greater HCI community, maintaining the agenda, and disseminating the agenda to research and funding organizations. Our primary objective is to build on previous efforts in order to develop a research agenda proposal that can be considered for endorsement by ACM SIGCHI.

Prospective participants are asked to review materials and references available on the workshop's web site, and submit a position paper identifying both breadth and depth issues for an HCI research agenda.

Please list:

• the areas you consider most critical and why
• the top five issues in your area of expertise

Issues may include process issues, such as how to connect HCI theory and practice. Participants will be selected based on the position papers, the need for participation across the diverse range of subfields that compose the HCI community, and the need for wide geographical representation.

Prior to the workshop, the organizers will assemble a working list of HCI areas and issues, which participants will be expected to review in advance of the workshop.

Workshop: 9. Organizing Web Site Information: Principles and Practical Experience

Kate Dobroth, American Institute for Research, USA
Paul McInerney, IBM, USA
Sharon Smith, Compaq Computer Corporation, USA

As web sites continue to grow in their complexity, one of the most important usability design decisions in web site design is how to structure the web site topic hierarchy. If anything is clear about the organization of web sites, it is that there is no single best way to go about it. Different types of web sites seem to demand different approaches to organization.

The primary purpose of this workshop is to discuss and develop solutions for organizing information in web sites taking into account:

• theories about how humans process categories
• solutions arrived in the course of the practice of web site design

We will select 10-20 participants with practical experience in web design and/or theoretical knowledge in relevant disciplines, e.g. cognitive psychology, library science, and information retrieval. Applicants should provide a position paper on their background and information on one or both of the following:

• Web design experience: describe up to three web sites you helped design or evaluate and include interesting issues in organization and categorization, as well as description of the content, size, users, user's tasks, usage patterns, topic hierarchy, rationale behind the topic organization, pre-design analyses (if any), and design evaluations (if any).
• Research experience: describe research (including hypotheses and supporting data) that you have done relevant to web site organization and categorization. We are especially interested in hearing about research that you have applied to the design of a site.

Workshop: 10. The Hunt for Usability: Tracking Eye Movements

Keith S. Karn, Xerox Corporation, USA
Steve Ellis, Lucent Technologies, USA
Cornell Juliano, Xerox Corporation, USA

Usability testing methods have not changed significantly since the origins of the practice. Studies typically measure time on task, success/failure, error types, etc. Some questions cannot be answered with these techniques. Imagine a user spending longer than expected looking at a screen without making appropriate selections. Is the user overlooking the appropriate control or distracted by another display element? Does the user see the control, but not comprehend its meaning? User's eye movements can offer additional insight.

Workshop Sub-topics:

1. Incorporating eyetracking in usability tests

• What questions are best addressed with this data?
• How does eye position data fit with other usability data?
• What eye movement measures are useful?

2. Interpreting eye movement data

• How to best process raw data?
• Do measures correspond to cognitive processes?
• Can we interpret data using theories of other disciplines using eye tracking?

3. Resolving technical issues with the eye tracking technology

• Which tracking technology is best?
• What type of calibration process is needed?
• How is the user constrained?

We welcome participation of anyone experienced in usability evaluation or eye movement research. Participants will be selected based on position statements that address questions listed in at least one of the three subtopics above, and a description of your work. Selection criteria are familiarity with the topic and potential for innovative contributions.

Other Activity: CHIkids and childcare

(Also available Sunday, Tuesday, Wednesday, and Thursday)

There are two options: the traditional child care option and CHIkids. CHIkids is a place where kids, adults, and technology come together with common goals and do meaningful things.

The philosophy of the CHIkids program is built around the belief that technology is a tool to learning. CHIkids is about what can happen when technology is a catalyst. With the tools of technology, children can be conference reporters, web designers, multimedia storytellers, software testers, conference attendees, and more!

The innovative CHIkids program has been expanded for CHI 99. CHIkids combines the feeling of summer camp with the fun of technology, all as a part of the unique conference experience. This year's CHIkids program will provide kids with new extended opportunities for meaningful technology experiences.

• The traditional child care option offers children 6 months to 3 years, fun-filled, developmentally appropriate activities.
• CHIkids provides children 3 to 15 years of age with educational, purpose-driven technology experiences. Children ages 3 to 7 will use CD-ROMs, test new software, as well as be provided with a mixture of off-computer activities to complement their technology experiences. Children ages 8 to 15 will be provided with two main areas of exploration: creating multimedia stories in the Multimedia Storytelling area and being conference reporters using desktop publishing tools and the web in the CHIkids Newsroom.

All CHIkids activities will be led by a team of CHI volunteers with experience in technology, kids, and fun! Assistance will be provided by KiddieCorp, our experienced child care facilitators. Each day, children will be able to choose among various activities. The registration fee is US$75 per day, and includes lunch, snack, and CHIkids T-shirt. An optional field trip will be offered for CHIkids, 8 years or older, on Thursday, 20 May.

CHIkids REGISTRATION
For more information, please contact KiddieCorp via email or phone. Space is limited, and there will be no on-site registration. Therefore, registration will be on a first-come, first-served basis. A waiting list will be formed if all spaces are filled. Waiting list registrants will be notified if space becomes available.

Workshop: 1. Basic Research Symposium

Yvonne Waern, Linkoping University, Sweden
John F. McGrew Pacific Telesis, Shared Services, USA

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. This 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 to bring 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 Research Symposium is for each participant to leave with a better understanding of the research methods, goals, and frontiers of a wider range of HCI disciplines. Each participant should contribute to the collective understanding and leave with new ideas for conducting, integrating, and applying research.

The BRS welcomes two types of submissions:

• Position Papers. Up to ten pages introducing your field and your work. Authors of accepted position papers will be given time to present their work in an interactive discussion format.
• Position statements. Up to two pages introducing you and your interests.

Workshop: 2. Interacting With Recommender Systems

Patrick Baudisch, GMD-IPSI, Germany
Loren Terveen, AT&T Research, USA

Recommender systems automate the process of passing experience from a community of users to an individual user who is about to make a decision. They support people in making recommendations and in finding a set of people who are likely to provide good recommendations for a given person.

This workshop will focus on user and usage aspects of recommender systems. The workshop will consider, among others, the following issues:

• for which domains and which communities of users are recommender systems appropriate?
• empirical evaluation of deployed systems
• can interest profiles be constructed automatically from implicit input?
• what types of incentives must be provided to motivate users to participate?
• how should recommender systems communicate their results to users?
• privacy aspects

Applicants should send position papers (3-5 pages, preferably in pdf format) to the organizers, articulating their interests, ideas, and experiences in recommender systems. Application demonstrations are strongly encouraged. We welcome people with a variety of insights and perspectives, e.g. HCI, artificial intelligence, visualization, information retrieval. Participants will be selected based on their position papers, while seeking to balance the perspectives and interests of participants. This workshop is limited to 15 participants.

All accepted position papers will be placed on a web site by the organizers. Participants will be expected to read the position papers of all 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 a report after the workshop.

Workshop: 3. Interacting in the Large: Developing a Framework for Integrating Models in HCI

Eamonn O'Neill, University of London, UK
Hilary Johnson, University of London, UK
Peter Johnson, University of London, UK

Modeling in early HCI concentrated largely on the individual user of a computer system. HCI has expanded its range of concerns to include the social, organizational, and environmental setting of interaction between possibly more than one user and more than one computer. The range of models used in HCI has correspondingly increased. The workshop objectives are to bring together researchers and practitioners in order to produce a shared understanding of what needs to be modeled and of the problems of integrating diverse models in interactive systems development; to provide suggestions of how to overcome those problems, and to undertake initial attempts at an integration of the models in an example domain. This example shall be provided by the workshop organizers in the form of a scenario of use in mobile computing. In the weeks before the workshop, the scenario will be circulated to the accepted participants.

Applicants should send position papers (2-4 pages) articulating the author's particular interest in the topic of the workshop; the author's background in modeling; an outline of a modeling approach with which the author has been associated either as a producer or as a user; and the author's experience with this approach. We envisage several papers coming out of the workshop which might comprise a special issue of a journal or an edited book.

Research in this field is interdisciplinary, drawing on diverse fields including anthropology, architecture, computer science, human factors engineering, political science, psychology, and sociology. This workshop aims to bring people from these diverse fields together.

Those desiring to participate should submit a position paper:

• summarizing what your research has shown about online communities,
• outlining future directions your research will explore, and
• highlighting a few additional questions that you feel are important to the future of the field.

Papers must be submitted in HTML to asb@cc.gatech.edu. A length of less than 2500 words is suggested. Accepted papers will be posted on a workshop website. After the workshop, some participants will be invited to expand their papers into book chapters.

The primary criteria for acceptance are relevance to the topic and soundness of research methodology. Work of a speculative nature will not be included. We will also try to ensure that a variety of disciplines are represented.

Workshop: 5. Designing Electronic Books

Gene Golovchinsky, FX Palo Alto Laboratory, USA
Cathy Marshall, Xerox PARC, USA
Bill Schilit, FX Palo Alto Laboratory, USA

Science fiction introduced the idea of an electronic book; some early prototypes showed the potential of such devices; now we have the technology to implement these ideas. Still missing, however, is a principled look at features and interaction design that make electronic books usable. Getting the user interface right is critical. We would like to apply the expertise of the HCI community to understand the work practices e-books support, and to inform interaction and user interface design.

This workshop will bring together practitioners, researchers, and designers to explore the future of electronic books with an emphasis on HCI issues. About twenty participants will be selected based on two- to four-page position papers on HCI issues (practical or theoretical) related to e-books. Accepted participants will be expected to submit longer versions of their papers to provide more detail. Papers should address one or more of the following issues slated for discussion at the workshop:

How will e-books fit into existing practices, and how will they change them? Which activities will benefit from such devices, and which are better left on paper?

Do e-book features depend on the document genre? Which features are appropriate for which tasks? Can we identify design guidelines for electronic books?

Is the book an appropriate metaphor for an electronic book? Does familiarity with the book outweigh some of its limitations? Can we identify other appropriate metaphors?

Can we describe the relationship between the form factor of an e-book and its software interface?

Workshop: 6. Interacting with Statistics: Designing Interfaces to Statistical Databases

Michael D. Levi, US Bureau of Labor Statistics, USA
Frederick G. Conrad, US Bureau of Labor Statistics, USA

Suppose you move to a new neighborhood. You might want to know if you should worry about crime, whether the local schools are good, or whether the drinking water is clean. In each of these cases the relevant information exists in statistical data bases (SDBs). Whether a typical information seeker can find the information, however, is another question.

The purpose of this workshop is to foster the development of better, more usable interfaces to statistical databases: large, numeric data sets concerned primarily with social science. We will focus on the HCI problems that are peculiar to communicating requests for statistical information and presenting the results in a usable form. The outcome of the workshop will include a catalogue of HCI problems related to statistical information, a set of implemented solutions with accompanying commentary, and a set of research topics.

Workshop participants must have concrete experience developing or evaluating interfaces to statistical databases. Applicants should send a 3 - 5 page position paper headed with name and contact information and a one-paragraph biographical sketch. The paper should summarize the types of statistical data sets they work with, the type of usability problems their intended audience typically faces, and one or more useful interfaces they have either designed or evaluated which attempt to overcome these problems. If possible, please email the paper using ASCII, HTML, or Microsoft Word.

Workshop: 11. End-User Programming and Blended-User Programming

Carol Traynor, St. Anselm College, USA
Howie Goodell, Micrion Corporation, USA

End-User Programming has not met expectations: today's computer world is dominated by "fatware" programs with hundreds of features, not simple applications built by the users themselves. Yet, a strange convergence is occurring between roles of programmers and end-users. Professional programmers become end users of complex IDEs (Integrated Development Environments) indistinguishable from tools for non-programmers. A new group we call "blended-user programmers" has appeared -- professional application experts without software degrees, e.g. web designers or GUI programmers. Major end-user applications support a continuum of programming tools; advanced users may move into these new software careers.

This workshop will re-evaluate insights of classical end-user programming to understand the converging programming world. Questions it may address:

• What are useful boundaries of "programming" in an environment of check-box customization?
• What are appropriate programming abilities for schoolchildren and adults to learn?
• What are commonalties/differences between new areas of blended-user programming and forms studied earlier?
• What technical and social interactions develop when "real" programmers with computer science degrees work with blended-user programmers?
• Do certificate courses primarily expand blended-user programmers' repertoire of tinkering, or make them more analytical?

Fifteen experts in end-user programming or with psychology and sociology of programming backgrounds will be selected based on position papers (2-4 pages). If appropriate, these may be published as a book to inform research and practice in this emerging area.

Workshop: 12. HCI in Domains: Common Ground and Key Differences

Guy Boy, Eurisco, France
David Novick, Eurisco, France
Cathleen Wharton, US WEST !NTERPRISE, USA

The workshop will discuss HCI approaches, methods, and techniques used in different domains such as health care, engineering, education, or entertainment. The main goal is to understand the interaction of domain and HCI issues. For example, are design guidelines domain-neutral or not?

Our objectives are to produce a categorization of HCI methods and practices across domains, identifying the type of systems in which a technique is most useful; the stage of development in which a methodology is appropriate; the resources needed to conduct an HCI project; and the appropriate measures for various techniques. We plan to discuss various methods of data collection for HCI in specific domains that would be of interest to others.

We expect participants to search for common ground across domains, to identify key differences, and to synthesize new methodologies, where possible.

Participants will be selected on the basis of a 4-5 page position paper describing their background, a large HCI project in one specific domain, and the general and domain-specific methods and techniques applied during all phases of development. Three domains will be chosen for discussion at the workshop on the basis of participants' statements of experience and interest. These three domains will be presented on a pre-workshop web site.

Workshop: 13. Designing the User Interface for Pen and Speech Applications

David Ferro, Unisys Natural Language Understanding, USA
James A. Larson, Intel Architecture Labs, USA
Sharon Oviatt, Oregon Graduate Institute of Science & Technology, USA

This workshop will bring together a small group of researchers and practitioners to discuss how to design applications with both a verbal user interface (the user hears and speaks to the application) and a visual user interface (the user draws/writes and sees the application). Our goals are to better understand the issues that face designers of multimedia interfaces supporting both visual and verbal interaction styles; to facilitate the exchange of ideas and information; and to increase communication among the extremely diverse groups involved in designing multimedia interfaces.

To be selected as a participant in this workshop, e-mail a 3-page paper to the organizers that describes: (a) an existing or proposed multimedia application that integrates visual and verbal interaction styles, and (b) brief position statements relevant to the following workshop topics:

1. Identify situations in which combined visual and verbal interaction is particularly useful, or in which switching between them is desirable
2. Identify principles and/or methodologies for designing visual/verbal human-computer interfaces
3. Recommend topics on which additional research is needed before effective visual/verbal multimedia interfaces can be designed.

A maximum of 15 applicants will be invited to participate in the workshop based on their unique insights and the diversity of viewpoints represented.

Other Activity: CHIkids and childcare

(Also available Sunday, Monday, Wednesday, and Thursday)

There are two options: the traditional child care option and CHIkids. CHIkids is a place where kids, adults, and technology come together with common goals and do meaningful things.

The philosophy of the CHIkids program is built around the belief that technology is a tool to learning. CHIkids is about what can happen when technology is a catalyst. With the tools of technology, children can be conference reporters, web designers, multimedia storytellers, software testers, conference attendees, and more!

The innovative CHIkids program has been expanded for CHI 99. CHIkids combines the feeling of summer camp with the fun of technology, all as a part of the unique conference experience. This year's CHIkids program will provide kids with new extended opportunities for meaningful technology experiences.

• The traditional child care option offers children 6 months to 3 years, fun-filled, developmentally appropriate activities.
• CHIkids provides children 3 to 15 years of age with educational, purpose-driven technology experiences. Children ages 3 to 7 will use CD-ROMs, test new software, as well as be provided with a mixture of off-computer activities to complement their technology experiences. Children ages 8 to 15 will be provided with two main areas of exploration: creating multimedia stories in the Multimedia Storytelling area and being conference reporters using desktop publishing tools and the web in the CHIkids Newsroom.

All CHIkids activities will be led by a team of CHI volunteers with experience in technology, kids, and fun! Assistance will be provided by KiddieCorp, our experienced child care facilitators. Each day, children will be able to choose among various activities. The registration fee is US$75 per day, and includes lunch, snack, and CHIkids T-shirt. An optional field trip will be offered for CHIkids, 8 years or older, on Thursday, 20 May.

CHIkids REGISTRATION
For more information, please contact KiddieCorp via email or phone. Space is limited, and there will be no on-site registration. Therefore, registration will be on a first-come, first-served basis.

Plenary: Sci-Fi @CHI: Science-Fiction Authors Predict Future User Interfaces

Aaron Marcus, Aaron Marcus and Associates, Inc.
Elliot Soloway, University of Michigan
Bruce Sterling, Science Fiction Author
Michael Swanwick, Science Fiction Author
Vernor Vinge, Science Fiction Author, San Diego State University

What will the human-computer interface be like in the future? Who better to speculate on the distant future of HCI than the people who do it professionally... science fiction authors?

Science fiction novels have recently featured neurochemistry, DNA-engineering, micro-manufacturing, silicon-carbon merging, and virtual reality. They portray distinct visions of user interfaces for computer-based communication, e.g., the use of direct neural-system implants, controlled hallucinations, and hay-wired virtual cyber-worlds. In these scenarios, the user interface becomes a fantastical interplay of dramatic personae, real and imagined, together with signs and symbols in three-dimensional, full-media environments.

Leading science fiction authors Bruce Sterling, Michael Swanwick, and Verner Vinge bring powerful visions about the impact of these new technologies and how we should evaluate their impact. Notable CHI persona, Eliot Soloway, will praise, denounce, and debate their views. Sci-Fi@CHI 92 was one of the most memorable and popular CHI events ever held. The panelists were provocative, opinionated, and outrageous�and played to a packed audience. Expect the same mental fireworks, and more, for SciFi@CHI 99. Arrive early, get a good seat, and feel the heat!

Bruce Sterling has authored Schismatrix, Islands in the Net, Heavy Weather, and Holy Fire. His nonfiction writings have appeared in World Art, Details, and Wired, and he is a popular speaker about high technology.

Michael Swanwick, the author of In the Drift, Vacuum Flowers, Griffin's Egg, Stations of the Tide, The Iron Dragon's Daughter, and Jack Faust, has received the Nebula, Theodore Sturgeon, and World Fantasy awards.

Vernor Vinge is best known for True Names, The Peace War, and Marooned in Realtime, which were both nominated for the Hugo Award, and for A Fire Upon the Deep, which won the Hugo Award. His newest novel is A Deepness in the Sky.

Panel discussant Professor Elliot Soloway researches, publishes, and develops products that explore the future of computers and education. He teaches at the University of Michigan, College of Engineering, School of Education, and School of Information.

Panel moderator Aaron Marcus of Aaron Marcus and Associates, Inc. has worked with Apple, AT&T, DARPA, Motorola, MCC, and NCR on advanced user interface designs that are five to 15 years ahead of commercial applications.

Plenary: How to Become an Internet Felon in Three Easy Steps

Barbara Simons

The ease with which digitized intellectual property can be duplicated, distributed, and accessed on the Internet has generated fear and misunderstanding of the net. These concerns have prompted legislation and regulations that could have the effect of restricting access to information and reducing privacy on the Internet.

The Internet has no national boundaries, and there is no international consensus on how to balance users' rights to privacy and users' rights to protection of their intellectual property. Legislation has been proposed throughout the world that could seriously affect the way that HCI professionals design and deliver interactive technologies.

Barbara Simons will describe some of the resulting potential dangers for HCI professionals and general users of the Internet. She will review current battles over copyright protections and privacy, and will describe how such laws could change the nature of our work.

Barbara Simons earned her Ph.D. in computer science from the University of California, Berkeley. She served as Senior Technology Advisor for IBM Global Services. Ms. Simons is a Fellow of ACM and of the American Association for the Advancement of Science (AAAS). She was elected president of ACM in 1998.

Ms. Simons is a winner of the 1998 EFF Pioneer Award. In 1995, CNET selected her as one of its 26 Internet "Visionaries"; in 1994 Open Computing named her as one of the top 100 women in computing; and in 1992 she was awarded the CPSR Norbert Wiener Award for Professional and Social Responsibility in Computing. Science Magazine featured her in a special edition on women in science in 1992.

Interview: Methodological Limits to HCI (with a special look at HCI and older users)

A Conversation with Wayne Gray and Bill Gaver

What do we really know about the relative benefit of the design and evaluation methods we use? What methods offer new opportunities? What opportunities exist for improving senior HCI? How do we find the methodological guidance we need?

WAYNE GRAY is Associate Professor of Psychology and Fellow of the Krasnow Institute for Advanced Study, at George Mason University. He is currently head of the Human Factors and Applied Cognitive Program. His notable work at NYNEX's Science & Technology Center included the development and application of CPM-GOMS to telephone operator workstations.

BILL GAVER is a Senior Research Fellow at the Royal College of Art in London. He has worked on media spaces, affordances, and virtual physics at Apple Computer, Rank Xerox EuroPARC, and the Delft University of Technology. Now he is focusing on "provocative awareness," the use of technology for aesthetic and cultural interventions.

Other Activity: CHIkids and childcare

(Also available Sunday, Monday, Tuesday, and Wednesday)

There are two options: the traditional child care option and CHIkids. CHIkids is a place where kids, adults, and technology come together with common goals and do meaningful things.

The philosophy of the CHIkids program is built around the belief that technology is a tool to learning. CHIkids is about what can happen when technology is a catalyst. With the tools of technology, children can be conference reporters, web designers, multimedia storytellers, software testers, conference attendees, and more!

The innovative CHIkids program has been expanded for CHI 99. CHIkids combines the feeling of summer camp with the fun of technology, all as a part of the unique conference experience. This year's CHIkids program will provide kids with new extended opportunities for meaningful technology experiences.

• The traditional child care option offers children 6 months to 3 years, fun-filled, developmentally appropriate activities.
• CHIkids provides children 3 to 15 years of age with educational, purpose-driven technology experiences. Children ages 3 to 7 will use CD-ROMs, test new software, as well as be provided with a mixture of off-computer activities to complement their technology experiences. Children ages 8 to 15 will be provided with two main areas of exploration: creating multimedia stories in the Multimedia Storytelling area and being conference reporters using desktop publishing tools and the web in the CHIkids Newsroom.

All CHIkids activities will be led by a team of CHI volunteers with experience in technology, kids, and fun! Assistance will be provided by KiddieCorp, our experienced child care facilitators. Each day, children will be able to choose among various activities. The registration fee is US$75 per day, and includes lunch, snack, and CHIkids T-shirt. An optional field trip will be offered for CHIkids, 8 years or older, on Thursday, 20 May.

CHIkids REGISTRATION
For more information, please contact KiddieCorp via email or phone. Space is limited, and there will be no on-site registration. Therefore, registration will be on a first-come, first-served basis. A waiting list will be formed if all spaces are filled. Waiting list registrants will be notified if space becomes available.

Interview: Organizational Limits to HCI

A Conversation with Don Norman and Janice Rohn

Why do organizations resist employing user-centered design methodologies? What forms does this resistance take? What can be done to avoid or overcome this resistance? Are any of the obstacles justified?

DON NORMAN is an executive consultant in human-centered design in the Nielsen Norman Group. He is former Vice President of Research at Apple Computer and Professor Emeritus of Cognitive Science, University of California, San Diego.

JANICE ROHN is Manager of Usability Labs and Services at Sun Microsystems and has been President of the Usability Professionals' Association. At a BayCHI program, Janice advocated the application of a user-centered design process to a company in order to achieve its user-centered design of HCI.

Plenary: Civil Rights in Cyberspace: How Online Free Speech Restrictions Will Inhibit Online Diversity

Ann Beeson, American Civil Liberties Union (ACLU)

In the past two years, courts in a variety of landmark cases have affirmed strong free speech rights for the Internet. Despite these victories, lawmakers continue to try to squelch the speech-enhancing and democratizing aspects of the online medium through poorly crafted laws and policies.

For example, despite the U.S. Supreme Court's unanimous condemnation of the Communications Decency Act, the U.S. Congress recently passed the Child Online Protection Act (COPA), which again puts online speakers at risk of severe criminal penalties for communicating protected speech to adults. COPA does nothing to protect children. But, if not enjoined, it will impose insurmountable burdens on content providers that will devastate small and home-based online businesses, and will eliminate many valuable interactive forums.

In addition, regulators in many places are forcing adults and minors to use blocking software when they access the Internet at public libraries and schools. The software is an arbitrary censorship tool which blocks access to a wide variety of valuable educational, political, literary, and artistic sites on the Internet -- including resources on women's health and safer sex.

Ann Beeson is staff counsel at the ACLU, where she works as a litigator to promote and protect civil liberties in cyberspace. She is a primary architect of the landmark case in which the U.S. Supreme Court in 1997 declared the Communications Decency Act unconstitutional and affirmed free speech rights in cyberspace. She is now lead counsel in the challenge to the second attempt by the U.S. Congress to impose criminal sanctions on protected Internet speech.

The Los Angeles Times named Ms. Beeson one of six "Stars of the Internet" for her work in safeguarding free speech in cyberspace, and she has been profiled as an "Internet Newsmaker" by CNET.
