Technical Program All-at-Once

Tuesday, May 18, 08:30 - 18:30

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. A waiting list will be formed if all spaces are filled. Waiting list registrants will be notified if space becomes available.

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.

Interview: Web and Web Design Limits to HCI

A Conversation with Clement Mok and Jakob Nielsen

Why are most web sites so unusable? Why do so many people lack the trust necessary for making a purchase via the web? Are branding and usability incompatible goals? What disciplines play key roles in the creation of meaningful and usable web sites?

CLEMENT MOK is Chief Creative Officer of Sapient and is founder of Studio Archetype and of CMCD and Net Objects. Creating meaningful connections between people, ideas, art, and technology is the focus of Clement's many design and consultative projects. Clement is author of Designing Business: Multiple Media, Multiple Disciplines.

JAKOB NIELSEN is a principal of the Nielsen Norman Group, a user experience consultancy. Until July 1998, he was a Sun Microsystems Distinguished Engineer. Jakob writes the bi-weekly Alertbox column on web usability. Jakob's most recent book is Designing Excellent Websites: Secrets of an Information Architect.

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.

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.
