Workshops:

W1: Component-Based Groupware [Salon 1]
Robert Slagter and Henri ter Hofte, Telematica Instituut, Netherlands, and Oliver Stiemerling, University of Bonn, Germany

The CSCW2000 workshop on component-based groupware provides a forum for discussion for researchers from different backgrounds, such as CSCW software development, distributed systems, component-based software and group communication.

We will discuss ways to combine approaches, as well as benefits, the state of the art, requirements and a research agenda. Results will support researchers, designers and software engineers in the design and implementation of groupware applications. The workshop should contribute to enhanced insight in the domain, provide a venue for feedback on research-in-progress, and the basis for further research.

The topics of interest for this workshop include:

  • CSCW component software architectures;
  • Types of components and how should they relate?
  • Key requirements and experiences developing component-based groupware systems/frameworks;
  • Enhancing existing component-based platforms for support of CSCW software engineering;
  • End-user composability versus design-time composabilty and its effect on component groupware architectures;
  • Standards for communication between components within and between different groupware systems.

W2: Awareness and the WWW [Salon 4]
Olivier Liechti and Yasuyuki Sumi, ATR MIC Labs, Japan

Awareness issues are becoming increasingly meaningful in the context of the WWW. The first reason is that Web technologies provide an implementation platform for awareness tools, with many benefits. The emergence of information appliances (not only mobile devices but also kiosks and public displays) is making the Web even more appealing to CSCW designers.

The second reason is that the WWW itself is becoming an activity space, which people should be made more "aware" of. For instance, information consumers should be able to "see" and meet each other when they visit related places on the Web. Also, information publishers should be able get a better idea of what is happening on their sites, in more natural, continuous and effortless ways.

The goal of this workshop is to bring together researchers from various backgrounds, having interest in one or both of these two aspects. We invite contributions from CSCW experts who have designed and evaluated awareness systems using Web technologies, such as media spaces, group awareness tools and persistent shared workspaces. We also seek for contributions from WWW and HCI experts, who have designed systems for making users aware of the activity occurring on the Web. Some of the systems we have in mind are collaborative browsers, on-line matchmaking tools, and ambient user interfaces.

W4: Classification schemes in cooperative work [Salon 6]
Kjeld Schmidt, Technical University, Denmark, Carla Simone, University of Torino, Italy, and Susan Leigh Star, University of California, San Diego, USA

Common information spaces, i.e., the shared repositories of cooperative communities, are a ubiquitous feature of modern work settings that have been the subject of a great deal of research in CSCW (under labels such as 'organizational memory' and 'knowledge management' as well). However, a central problem in this context has so far not been investigated systematically within CSCW, namely the classification schemes that communities use for managing their shared repositories and, more specifically, the distributed practices through which classification schemes are developed and maintained.

The objectives of the workshop are to direct attention to this problem, collate and inspect available empirical evidence as well as innovative technologies, identify crucial research issues, and, in doing so, establish a network of CSCW researchers working on these issues.

W5: Exploring the Framework of Context Awareness in Cooperative Systems [Parlor D]
Ted Selker and Winslow Burleson, MIT Media Lab, USA

Context aware computing deals with gathering information through non-explicit inputs and appropriately applying this information to assist users in task performance. It is becoming an increasingly important topic in the fields of HCI and CSCW.

This workshop proposes to discuss a framework in which context aware sensor, artificial intelligence, and effector based computers coexist in the world. This framework should be of great value to the production of cooperative context aware systems as well as a guide for directing further research efforts.

The tension between specific solutions and generalized infrastructures has always existed. In the context aware computing environment it becomes even more poignant because in many ways it deals with how much context can be achieved, how many things you can understand, and how general the interfaces are.

Research experiences and position statements will be presented in an effort to develop a focused community on these issues. We will explore how in a world of non-standardized components context aware computing can emerge, survive, and progress as well as how to make the most of context aware systems and applications.

W7: Lifecycle Support for Collaborative Science [Salon 2]
Richard M. Keller, NASA-Ames Research Center, USA and Jon Guice, RIACS, NASA-Ames Research Center, USA

The focus of this workshop is the application of CSCW theory, tools, and techniques to the practice of day-to-day scientific work. Most prior work on scientific collaboration has focused on support within a single phase of the scientific lifecycle, e.g., experimentation. In contrast, this workshop will explore how CSCW tools can be used to support and integrate work performed throughout the scientific lifecycle -- from proposal generation through experiment design, experimentation, data collection, analysis, and publication. Workshop activities are intended to identify open research issues and foci unique to this community. We wish to invite participants who will share: Characterizations of routine scientific work practice. Analyses of phase-specific requirements for collaborative science support. Strategies for building tools serving multiple scientific communities. Reports on limitations of technology supporting scientific work. Insights into the impacts of e-commerce and scientific information services on the practice of science. Accounts of social barriers to information-sharing in science. Reflections on methodologies for studying scientific teams.

W8: Shared Environments to Support Face-to-Face Collaboration [Salon 5]
Kori Inkpen, Regan Mandryk, and Stacey Scott, Simon Fraser University, Canada, and Saul Greenberg and Ana Zanella, University of Calgary, Canada

As computer technology continues to move off the desktop and into the many facets of our lives, the need to support collaboration is growing rapidly. Better technical solutions are needed to support users face-to-face collaborative interactions in a variety of domains, including at work, home, and school.

Technical advances such as large screen displays, support for multiple input devices, coordination of distributed room displays, and collaborative tangible interfaces will provide better support for small-group interactions. Research on issues of privacy and awareness, collaborative interfaces, social artifacts, and better ways to transition between individual and collaborative sessions will also facilitate the collaborative process. This workshop provides researchers a forum to discuss and brainstorm about shared environments for face-to-face collaboration. The goal is to bring together individuals with common research interests to identify emergent directions. This workshop will allow individuals with diverse and complementary research experiences to build a collective understanding of the issues surrounding user interactions in shared environments.

W9: Beyond Workflow Management: Supporting Dynamic Organizational Processes [Seminar A]
Abraham Bernstein, New York University, USA and Stefan Jablonski, Friedrich-Alexander Universitaet, Germany

Today's organizations are characterized by dynamic, uncertain and error-prone environments. In order to effectively support processes in such contexts, systems must be developed, which support truly dynamic organizational processes.

Existing workflow management systems have typically been focused on dealing with exceptions and have thus offered some type of approach to support adaptive processes. These types of systems, however, have typically overlooked emergent processes, which seem to encompass an increasing part of organized activity.

The goal of this workshop is to provide researchers a rare opportunity to discuss and brainstorm the social as well as technical considerations that have to flow into the design of systems to support truly dynamic organizational processes that include both adaptive as well as emergent organizational processes.

W10: Technologies That Cross Boundaries: Exploring the gap between wireless networks, bits, interfaces, and work practices [Salon 3]
Elizabeth F. Churchill, Jonathan Trevor, and Catherine C. Marshall, FX Palo Alto Laboratory, USA

The proliferation of mobile technologies is challenging notions of appropriate places for work. These technologies by their very nature move through private and public spaces. We have access to others and to our data, anywhere, anytime; we can be in contact, available for social and work interactions, while carrying some of our most critical and sensitive data across physical and social boundaries. Previously, design has focused on the cognitive affordances of the interfaces and the social affordances of the group in which it fits. Now we need to think about the implications that situational affordances bring. In this workshop we will explore what this means for the design of systems, interfaces, networks and data. We encourage those with:

  • Accounts of mobile CSCW.
  • Analyses of embedded assumptions about accessibility, availability and connectivity in mobile designs.
  • Experience in the design of mobile CSCW systems.
  • Fieldwork reports and methodological reflections for studying mobile cooperative work.

W11: Shared Visual Spaces in Face-to-Face and Video-Mediated Collaborative Work [Parlor B]
Robert E. Kraut, Susan R. Fussell, Jane Siegel, and Jie Yang, CMU, USA, and Susan E. Brennan, SUNY Stoney Brook, USA

Studies of video technologies in collaborative work have yielded mixed results about benefits for communication and performance. In this workshop we strive to develop a theoretical and empirical framework to better understand the role of visual information in collaborative work and to make informed design decisions about video technologies. Each panel presentation/ discussion session focuses on one of 3 goals:

  1. a conversational coding scheme that captures how people make use of shared visual space when they converse face-to-face,
  2. a taxonomy of collaborative physical tasks that illuminates the relationships between task attributes and needs for shared visual information, and
  3. a set of recommendations for the design and implementation of video technologies to support "virtual" shared spaces in remote collaborative physical work.

Attendees will present at one panel and participate in the discussion for the other two. Interested participants should indicate their choice of panel and provide a brief (one or two paragraph) description of the work they will present and its relation to the themes and goals of the workshop.

W12: Dealing with Community Data [Parlor A]
Amy Bruckman, Georgia Institute of Technology, USA, Thomas Erickson, IBM T. J. Watson Research Center, USA, Danyel Fisher, University of California, Berkeley, USA, and Christopher Lueg, University of Zurich, Switzerland

As online communities move through their life cycles, most are continually accreting data, both as user-visible content and in behind-the-scenes data logs. This workshop will focus on the collection, use, and analysis of this data. We will examine storage and logging mechanisms, discuss both qualitative and quantitative approaches to analysis, and consider ways in which this data -- the history of a community's activities -- might be used by its members, its administrators, and by researchers.

W13: Collaborative Editing Systems [Salon 9]
Du Li, Texas A & M, USA, Jeffrey Campbell, University of Pittsburgh, USA, David Chen and Chengzheng Sun, Griffith University, Australia, Clarence Ellis, University of Colorado, USA, and Matthia Ressel, UBS AG, Switzerland

Collaborative editing systems are an important category of groupware which support a group of users to edit the same document collaboratively over the computer networks synchronously or asynchronously. Interesting document types include text, graphics objects, multimedia data, and diagrams. A wide variety of research areas contribute to collaborative editing including group awareness, concurrency control, social interaction, usability and human factors as well as areas such as distributed computing. We organized a very successful workshop on collaborative editing systems joint with the ACM Group'99 Conference. In this ACM CSCW 2000 workshop, we would like a more in-depth discussion of the following topics: concurrency control and consistency maintenance in group editors, usability study of group editors and human factors, social aspects of collaborative editing, and application of group editing techniques and algorithms in distributed applications.

Sunday full-day

T2: A Technical Overview of CSCW
Instructor: Prasun Dewan, University of North Carolina - Chapel Hill, USA

Origin: An update of a highly-rated CSCW 98 tutorial.

Goals and content: In the past decade, a variety of systems (applications and infrastructures) have been developed to support collaboration. These systems have been developed in diverse fields including user-interfaces, multimedia, programming languages, computer hardware, distributed systems, Java middleware and hypermedia. This tutorial will take the audience on a tour of these systems, discussing technical issues that arise in their design and implementation.

Intended audience: This tutorial will appeal to practitioners interested in state-of-the-art collaborative applications and infrastructures, and researchers interested in understanding the technical issues raised by the design of these systems. The tutorial will assume that the audience are software developers, but will make no assumptions about their familiarity with the field of CSCW. Thus it will be accessible to ``beginners'' in this field.

About the instructor: Prasun Dewan is Professor of Computer Science at the University of North Carolina. His research interests are in infrastructure for implementing groupware, collaborative software engineering, object-oriented database systems, and distributed operating systems. He is also Associate Editor of ACM Transactions on Information Systems, Associate Editor of ACM Transactions on Human Computer Interaction, and a member of the IFIPWG2.7 group on Engineering for Human Computer Interaction.

T6: Developing Web-based Collaborative Applications-Social and Technical Issues
Instructors: Alison Lee, IBM T. J. Watson Research Center, USA, Andreas Girgensohn, FX Palo Alto Laboratory, USA, and Catalina Danis, IBM T. J. Watson Research Center, USA

Origins: A substantially revised version of a highly-rated CSCW 98 and CSCW 96 tutorial.

Goals and Content: Once limited to serving information and facilitating transactions, the World Wide Web is increasingly being used to support collaboration for work groups as well as non-work-related groups. Our goal is to discuss the social and behavioral aspects of collaborative interactions and to describe how Web technologies can be used to build applications to support these. We will look at CSCW research and commercial collaborative applications to identify the necessary set of features. The tutorial will examine alternative implementations of awareness, social visualization, chat, and shared workspaces. We will highlight ways to use the Web as a development platform, and compare their suitability for implementing collaborative applications. At the end of the tutorial, participants will be aware of the elements to consider in Web-based collaborative applications and will be able to use Web technologies to build such applications.

Intended audience: This intermediate-level tutorial is intended for researchers, designers, and developers working in CSCW or Web applications to explore, design and build Web-based collaborative applications. In particular, this tutorial is of relevance to individuals interested in understanding issues related to social as well as technical elements needed in collaborative applications.

About the instructors: Alison Lee, Andreas Girgensohn, and Catalina Danis have different backgrounds in computer science, psychology, and human-computer interaction. They have developed tools and methodologies to support distributed work groups. In the last six years, much of this development work has been carried out using Web technologies. They have presented papers and tutorials at HCI-related and CSCW-related conferences.

T7: Theoretical Foundations of Collaboration and Learning (CANCELLED)
Instructor: Timothy Koschmann, Southern Illinois University, USA

This tutorial has been cancelled.

T8: An Overview of Distributed Teams, Organizational Coordination, and Virtual Communities
Instructors: Steven Poltrock, The Boeing Company, USA and Jonathan Grudin, Microsoft Research, USA

Origins: This is an update of a highly-rated tutorial presented at many CSCW and CHI conferences

Goals and content: You will learn about technologies being used to support groups and organizations. You will hear about successes and problems that are encountered. You will see how different disciplines contribute to collaborative systems and how these technologies affect individuals, groups, organizations and society. The tutorial has sections on support for small groups, for organizations, and on emerging support for communities. You will discover the multi-disciplinary nature of computer supported cooperative work; understand behavioral, social, and organizational challenges to developing and using these technologies; learn successful development and usage approaches; and be able to anticipate future trends in technology use and global social impacts.

Intended audience: This introductory tutorial is for actual and potential users, developers, researchers, marketers, or managers of CSCW or groupware systems. Broad experience with collaborative technologies is not expected.

T12: Community Knowledge
Instructor: Kari Kuutti, Helsinki University of Technology, Finland

Origins: This was a workshop at ECSCW'99.

Goals and content: The notion of "community knowledge" concerns community computing, knowledge management, organizational memory, and computer supported cooperative learning. It is expected that the supporting of communities might become one of the important growth areas in the use of Internet in the near future. The aim of the tutorial is to help in understanding the community knowledge field better by giving an overall view of this related work, reviewing the current status of the community knowledge research, and discussing about motivations, approaches, problems and challenges of the research. The focus of the tutorial is not in the technical systems, but in conceptual, psychological, social, and organizational issues related in generating, maintaining and sharing community knowledge.

Intended audience: We encourage participants not only from computing and information sciences but from a wide range of disciplines that are involved in this enterprise, such as social sciences, organizational psychology, business, to offer an opportunity for exchange of approaches from different perspectives.

About the instructor: Kari Kuutti is a Professor in the Department of Information Processing Science at the University of Oulu. He is also a member of the advisory board of the Center for Activity Theory and Developmental Work Research at the University of Helsinki.

T13: Distance Learning
Instructor: Lisa Neal, Electronic Data Systems, USA

Origins: An update of a highly-rated CHI'98 and CHI'99 tutorial.

Goals and content: This half-day tutorial covers how to design and deliver distance education. The motivation for distance learning programs is presented, along with the selection, deployment, and use of distance learning technologies. A variety of synchronous and asynchronous technologies are being used to replace or supplement the face-to-face classroom. Categories of technologies and specific products within each category will be covered, along with an examination of their benefits and problems. Many factors influence appropriate selection and deployment, such as time zones, international issues, bandwidth, and student and faculty technology literacy. We examine how preparing, teaching, and supporting a distance learning class differs from a face-to-face class and present techniques for delivering distance learning classes, including how to compensate for the absence of visual cues, how to keep students engaged and motivated, and how to evaluate the effectiveness of a distance learning class. Case studies will illustrate the use of distance learning technologies and the broad range of situations in which distance learning is employed.

Intended audience: This introductory tutorial is designed for actual and potential professors, facilitators, designers, or managers of corporate, university, or continuing distance education. No background in collaborative technologies is necessary, although exposure or experience will be helpful.

About the instructor: Lisa Neal is a senior research engineer at Electronic Data Systems. She has developed and delivered distance learning classes for five years, and consults with organizations that are setting up distance learning programs.

T14: Computer-Supported Community Work -- Fundamentals and Applications
Instructor: Doug Schuler, Evergreen State College, USA

Origins: An update of a highly-rated CSCW 98 tutorial.

Goals and content: Increasing worldwide use of the Internet by millions of new users with divergent allegiances, motivations, and habits introduces unique requirements for communication systems. Specifically, meeting the demands of diverse use will require re-analysis of social, political, economic, and technical factors to produce effective technology. Meeting this challenge, clearly within the domain of CSCW, could easily be dubbed "public CSCW" or "Computer Supported Community Work." This tutorial is designed to introduce CSCW researchers and developers to the growing field of public CSCW applications, services, and institutions. It is the goal of this tutorial to present innovative work in this area in addition to the major technological and social challenges and opportunities involved in this endeavor. We will also discuss the future of these new systems. Each participant should, after attending this tutorial, have a much clearer idea of what systems are being developed, or might be developed, and what they can do to make computer-supported community work a reality.

Intended audience: This tutorial is open to any interested person at any level of technical expertise.

About the instructor: Doug Schuler teaches in Computers and Society topics at The Evergreen State College and is one of the founders of the Seattle Community Network, a free, public computer network with over 12,000 registered users.

Sunday afternoon

T15: Social Science Findings for CSCW Designers
Instructor: Mark Ackerman, University of California Irvine, USA

Origins: This tutorial is new for CSCW 2000.

Goals and content: There is a growing body of social science findings that are important for those designing and building CSCW systems and applications. This tutorial aims to provide software engineers, user experience designers, and others with the core social science results relevant to CSCW application development. We will discuss, among many other findings, those studies that examine awareness of what other people need to know about collaborative activities. Since social science findings are often dependent on the methodological and theoretical bases of that work, this tutorial will also provide a general overview of the theories and methods used in CSCW. The goal is to provide the understanding needed to successfully integrate social science findings into system work, and to teach designers and developers to become more sophisticated consumers of social science work.

Intended audience: Technical people who would like to know more about the social science side of CSCW.

About the instructor: Mark Ackerman is an Associate Professor of Computer Science at the University of California, Irvine. Mark is the author of numerous CSCW papers and articles, including work on Answer Garden and organizational memory. He was the tutorials co-chair for CSCW 98.

T16: An Introduction to Collaboratory Construction
Instructor: Atul Prakash, University of Michigan, USA

Origins: A highly-rated ECSCW'99 tutorial.

Goals and content: This tutorial is intended for people who want to design and deploy web-based collaboration systems or understand the available design options and the tradeoffs. Examples of several web-based online communities, MUDs, education-support tools, and groupware tools, as well as instructor's own experience in building web-based scientific collaboratories will be presented. You will get a view of the functionality and architecture of these systems, the underlying technologies used, and tips on getting started on rapid prototyping of similar systems. The main emphasis is on (a) understanding the design approaches that are likely to work well in practice for the Web and (b) avoiding those that are likely to turn out to be expensive mistakes. You will get an overview of several web-related technologies such as web servers, Java, servlets, databases, cookies, web caching, signed applets, and plugins, and learn when they are useful in designing collaborative Web-based systems. Tradeoffs among various approaches in terms of performance, user-interface, group awareness, scalability, ease of deployment and updates, and impact on the CSCW system architecture will be presented.

Intended audience: Users, designers and builders of Web-based systems for collaborative science and engineering.

About the instructor: Atul Prakash is an Associate Professor in the Department of Electrical Engineering and Computer Science at the University of Michigan.

Invited Talks

Opening Plenary  (Monday, December 4, 9:00am - 10:30am, Ballrooms C & D)

Bowling Alone: The Collapse and Revival of American Community
Robert D. Putnam, Harvard University, USA

Over the last generation, Americans have deserted the voting booth, the church pew, the union hall, the PTA, the family dinner table, and even the bowling league and coffee klatch. This resulting loss of social capital -- ties of trust and reciprocity that further collective action -- has impaired our ability to provide well-functioning schools, safe streets, rapid economic growth, effective government, and even healthy lives. Americans have addressed similar problems at earlier periods in our history. If we are to do so again, computing and communications technology will have to be part of the solution, suggesting an important role for CSCW researchers and developers.

About the speaker: Robert D. Putnam is the Peter and Isabel Malkin Professor of Public Policy at Harvard University. He is also the director of the Saguaro Seminar, a national workshop for civic leaders on civic engagement. Previously, he served as the Dean of the Kennedy School of Government at Harvard. He is a fellow of the American Academy of Arts and Sciences and a member of the Trilateral Commission. In June, Simon and Schuster published his book, Bowling Alone: The Collapse and Revival of American Community. He is the author of six previous books, including, most recently, the award-winning Making Democracy Work: Civic Traditions in Modern Italy. His articles have appeared in The New York Times, The Washington Post, The American Prospect, and many other publications. He lives in Lexington, Massachusetts, and Jaffrey, New Hampshire.

IT2: An Information Technology Initiative for the Twenty-first Century -- NSF Plans for Implementation
Ruzena Bajcsy, Assistant Director, Directorate for Computer and Information Science and Engineering, National Science Foundation, USA

This presentation is divided into two parts. In the first, the IT2 Initiative is explained in some detail. We shall elaborate on the scientific content of this program, pose some open questions, and outline the path we at NSF plan to pursue to achieve the program goals. In the second part of the presentation, we shall discuss the identity of computer science as a scientific discipline and its relationship to other physical sciences, such as physics, chemistry, and molecular biology. We shall also focus on the "information science of computer science" and, in particular, what lessons we can derive from these other disciplines with respect to the representation of information content. Finally, we shall speculate on the future of our discipline and the challenges stemming from it. We hope to convey the excitement of perhaps a new emerging discipline anchored in information science.

About the speaker: Dr. Ruzena Bajcsy ("buy chee") is Assistant Director for the Computer Information Science and Engineering Directorate (CISE) at the National Science Foundation. As head of NSF's CISE directorate, Dr. Bajcsy manages a budget of approximately $300 million annually. Dr. Bajcsy is a pioneering researcher in machine perception, robotics and artificial intelligence. She is a professor at the University of Pennsylvania both in the Computer and Information Science Department and in the Mechanical Engineering and Applied Mechanics Department and is a member of the Neuroscience Institute in the School of Medicine. She is also director of the university's General Robotics and Active Sensory Perception Laboratory, which she founded in 1978. Dr. Bajcsy has done seminal research in the areas of human-centered computer control, cognitive science, robotics, computerized radiological/medical image processing and artificial vision. She is highly regarded not only for her significant research contributions but also for her leadership in the creation of a world-class robotics lab, recognized world wide as a premiere research center. She is a member of the National Academy of Engineering as well as the Institute of Medicine.

Closing Plenary  (Wednesday, December 6, 4:30pm - 6:00pm, Ballrooms C & D)

Got a Minute? How Technology Affects the Economy of Attention
Warren Thorngate, Professor, Psychology Department, Carleton University, Ottawa, Ontario, K1S 5B6, Canada

It is impossible to get information in or out of our head without paying attention. Yet attention, as Herbert Simon has noted, is a limited resource. As a result, exchanging attention for information not only defines communication, it is also provides the sufficient conditions for an economy of attention based on principles rather different than those taught in traditional economics courses. Some of these principles allow us better to understand the recursive evolution of information, communication and attention technologies, the first two assisting us to produce and distribute information, the last assisting us to consume it. Other principles allow us to speculate about the social and organizational consequences of this recursive evolution by distinguishing information that reduces demand for additional attention from information that increases it. My talk will outline some of the principles of attentional economics and sample some of their implications for Computer Supported Cooperative Work.

About the speaker: Following an unsuccessful career as a classical guitarist, Warren Thorngate received his BA in Psychology and Mathematics from the University of California, Santa Barbara, then fled to Canada to obtain two more psychology degrees at the University of British Columbia, specializing in the study of human decision making and social behavior. Twenty-five years ago he began to write about evidential statistics, the limits of research methods, the evolution of adjudicated contests and the economics of attention, ideas leading him to a term as president of the International Society for Theoretical Psychology but otherwise ignored. A chance opportunity for adventure led him to spend over a decade developing and evaluating computer mediated communication and information science projects in Latin America, culminating in the creation of Internet facilities at the University of Havana. While working on these projects, he became a founding member of the Computer User Research and Evaluation (CURE) group at Carleton University. Good fortune and helpful colleagues allowed him to serve as visiting professor in Berkeley, Leningrad, Melbourne, Havana, Santiago, Warsaw and Tehran. He is currently writing a book on the Economics of Attention which will include ideas from this presentation.


 

Panels

Instant Messaging: Products Meet Workplace Users
John C. Tang (Chair), Sun Microsystems, Inc., USA, Austina De Bonte, Microsoft, USA (MSN Messenger Service), Mary Beth Raven, Iris Associates, USA (Lotus Sametime), and Ellen Isaacs (workplace IM user), AT&T Labs - Research, USA

The popularity of Instant Messaging (IM) in on-line socializing has begun to migrate to use in the workplace. Many users are finding that the awareness and immediate contact that IM offers fills a missing niche in the technologies traditionally used in corporate settings to help keep colleagues connected over distance. Yet IM use in the workplace may have different design requirements than the online socializing context. This panel brings together representatives of some of the commercially popular IM systems and people who use IM in the workplace to raise the question of how the design of IM systems might need to evolve to meet the needs of workplace users.

The Children's Challenge: New Technologies to Support Co-Located and Distributed Collaboration
Allison Druin (Chair), University of Maryland, USA and KTH, Sweden, Steve Benford, University of Nottingham, UK, Amy Bruckman, Georgia Tech, USA, Kori Inkpen, Simon Frasier University, Canada, and Shelia O'Rouke, MaMaMedia, USA

In this panel, we will explore the various issues surrounding technologies, children and collaboration. Panelists will discuss the challenges of developing new technologies for co-located as well distributed collaboration. Issues surrounding interface design for children will be discussed, along with an exploration of possible software and hardware changes that can and should be made to our existing desktop environments. Panelists will be asked questions not only from the audience, but from children, parents and teachers video-taped for the presentation.

Research at Internet Speed: Is It Necessary?
Irene Greif (Chair), Lotus Research, USA

What pressures do dotcom's put on academic and commercial research institutions? The first concern is whether start-ups are draining research labs and universities of their talent. But the frenzied activity and constant innovation on the internet force research scientists to prove their value, and they may be skewing their research to near term. Is it necessary for science to move at internet speed? Is it possible? What is lost?

Panelists from both research labs and startups will respond to these questions, as well as what commercial settings may offer for CSCW research. Large scale collaborations may be advanced best by commercial interests -- likewise for educational reform through technology. But research on social impact of installing broadband in low income housing, for example, may be neglected in the emphasis on commercial viability.

Beyond Bowling Together

Participation in bowling leagues, religious, and civic organizations often creates social relations that are a resource for future activity that benefits the participants. These productive social relations are sometimes referred to as social capital. This panel will explore whether these forms of participation and the forms of social capital they generate should be the gold standard to which CSCW designers and evaluators should aspire, or whether there could be something better. First, we will explore new forms of participation that CSCW enables. Second, we will assess whether these new forms of participation generate productive social relations, and ask whether it matters that the social relations may only be productive in the continued presence of technology to mediate future interactions.
