CHAIR'S INVITATION
----------------------------------------------------------------------------

Welcome!

INTERCHI '93 is not just another conference. The unprecedented
combination of CHI '93 and INTERACT '93 has created not a new
conference, but a new partnership between the two leading professional
organisations in the field of human-computer interaction. The
ACM/SIGCHI (Association for Computing Machinery / Special Interest
Group on Computer and Human Interaction) conference was first held in
1982. SIGCHI has evolved from its origins as a North American
organisation to serve an international community, but the CHI
conference has never before left the North American continent. The
INTERACT conference, organised on behalf of IFIP-TC 13 (International
Federation for Information Processing, Technical Committee 13 on Human
Computer Interaction), has been held every 3 years since 1984. INTERACT
has been an international conference from the beginning but until this
year has maintained a decidedly European focus.

The theme of the conference, Bridges Between Worlds, offers several
interpretations. The field of human-computer interaction (HCI) today
spans many different cultures. Significant gaps between industry and
academia, between research and application, and between users and
developers can still be seen. INTERCHI '93 will attempt to bring these
communities together.  Increasing the focus on user interfaces and
cooperation technology will help to bridge the gaps between people and
their work and between people working together. The year 1993 is,
indeed, a time for building bridges in the HCI community and the world
at large. Amsterdam has been chosen as the site for the first joint
effort linking INTERACT and CHI, but the bridges we are building
stretch much further. Participants from every continent will provide a
breadth of perspective that has never been equalled in the field of
human-computer interaction.

INTERCHI '93 itself has much to offer, but we hope you will also take
the opportunity to cross some of Amsterdam's historic bridges and taste
the atmosphere of a city that has been famous for centuries for its
cosmopolitan population and its all-embracing outlook on life.

Workshops	Saturday and Sunday, 24-25 April                       pg. 2
----------------------------------------------------------------------------

Workshops provide an extended forum for small groups (15-20 people) to
exchange views on topics of common concern. INTERCHI '93 offers eleven
workshops covering a wide range of issues in HCI. Workshops last 1-2
days and are held before the conference, on Saturday and Sunday, 24-25
April. Workshop participants will be charged an additional registration
fee.

Workshop participants are selected on the basis of position statements
outlining the participant's views on the workshop theme and reason for
interest in the workshop topic. Statements are typically 1-3 pages in
length (exceptions are noted in the workshop descriptions to follow)
and should be submitted directly to the appropriate contact person. The
contact person can provide additional information about the workshop in
question.

A brief biography summarising the participant's background, relevant
experience, and current research or design activities should be
submitted with the position statement, along with complete contact
information (name, address, e-mail, telephone, and fax, if
appropriate).

Note: Position statements for all workshops must be received by 
5 February 1993.

Reflective Practitioners: Magic to Methodology
----------------------------------------------------------------------------
Cynthia Rainis, Digital Equipment Corporation

Saturday, 24 April

How do you think about design? What methods do you use to understand
how you or others design? How do you capture that individual and often
intuitive "magic" that skilled HCI designers seem to perform?

Although a number of data gathering techniques have been tried, the
actual process of design remains poorly understood. The goals of this
workshop are to discover and share methods and to develop a pooled list
of techniques for systematically capturing and documenting HCI design
practice and methodology.

While the focus of this workshop will be on practice rather than
theory, we hope participants will reflect the full range of people,
both practitioners and researchers, who are trying to understand
methods and practice in a systematic way. Participants will be selected
on the basis of their current work, methods of reflection, and reasons
for interest in the workshop, along with their willingness to complete
a pre-workshop design exercise.

Rethinking Theoretical Frameworks for Human-Computer Interaction
----------------------------------------------------------------------------
Yvonne Rogers, University of Sussex 
Liam Bannon, University of Copenhagen 
Christian Heath, University of Surrey 
	
Saturday afternoon and Sunday, 24-25 April

The major goals of this workshop are to provide a forum where HCI
researchers can discuss current concerns over the state of (cognitive)
theory, to examine more closely a number of alternative or extended
frameworks that have been proposed, and to seek some consensus on the
relative strengths and weaknesses of different approaches to particular
problems. The recent "turn to the social" will come under scrutiny.
Particular emphasis will be placed on work incorporating an analysis of
the role of artifacts and other social factors in the accomplishment of
work activities.

Position statements should either make a case for a particular
theoretical position, describe the success or failure of particular
approaches, or attempt some form of rapprochement between particular
frameworks. Contributions describing the relation between theory and
practice will also be welcome.

Gerard Ligozat, LIMSI, Universite Paris-Sud 

Saturday afternoon and Sunday, 24-25 April

Multimodal interfaces are extending the scope of HCI into new domains
through advances such as notepad computers and virtual reality systems.
Multimedia and combined interfaces (e.g., gestural interaction systems)
are also beginning to attract users.

The primary goals of this workshop are to define the basic concepts of
multimodal and multimedia (MM&MM) HCI, to establish a common framework
for continued discussion, to explore existing technology and
interaction techniques in order to identify promising directions for
the next generation of MM&MM HCI, and to survey existing approaches
from the perspectives of new technologies targeting innovative
applications.

We invite participants from industry, applied research, and academia to
discuss the pros and cons of interaction styles and media usage in
different cultures and to attempt to bridge the gaps between designers
of interactive systems, HCI researchers, and providers of development
tools.

Human-Computer Interaction Advances Derived from Real-World Experiences
----------------------------------------------------------------------------
Michael E. Atwood, NYNEX Science and Technology, Inc.  
Jean McKendree, University of York 

Saturday afternoon and Sunday, 24-25 April

HCI is an applied science in which advancement depends on the
validation of theories and techniques in the solution of real-world
problems. The goal of this workshop is to provide a forum in which to
share HCI advances derived from real-world settings and to discuss ways
to make the transition from the laboratory to the real world more
common and more timely. The focus will be not on the exchange of "war
stories", but rather, on the description of HCI advances that can be
shared with others and on the identification of major problems impeding
their migration from laboratory to end-user.

Participants from both research and practice orientations are sought
from all disciplines. To apply, submit a 3-8 page position statement
including the number and nature of end-users, the approach to design
and implementation, the real-world obstacles and lessons learned, the
HCI advances derived, and the things you might do differently next
time.

Advances in Teaching the HCI Design Process
----------------------------------------------------------------------------
Jenny Preece, Open University 
Peter Gorny, University of Oldenburg 
Tom Hewett, Drexel University  
Jean Gasen, Virginia Commonwealth University  

Saturday and Sunday, 24-25 April

Teaching real-world processes, such as computer system design, is 
made particularly difficult by the young and rapidly evolving nature 
of the HCI discipline. HCI educators must present design in as 
meaningful and coherent a way as possible whilst at the same time 
acknowledging real-world practices.

In this workshop we will briefly review typical lifecycle oriented 
software design and then examine two approaches which provide ways of 
focusing on HCI design concerns. The first combines visualising the 
conceptual aspects of the design with rapid iterative testing whilst 
the second focuses on designing for socio-technical issues. We will 
discuss the advantages of each approach and consider how to teach them 
to students.

The overall aim of this workshop is to advance and innovate teaching of 
HCI design. To apply, submit 3 copies of a 1-2 page position statement 
about a particular aspect of HCI design for which you have developed an 
innovative teaching technique.

Cost Effective Usability Engineering: Practical Strategies and Techniques
----------------------------------------------------------------------------
Nigel Bevan, National Physical Laboratory
Anne Schur, Battelle Pacific Northwest Laboratories  

Saturday and Sunday, 24-25 April

The objectives of this workshop are to identify, from the best of
current practice, the strategies, techniques, and tools which can be
most appropriately applied in different design environments to ensure
the usability of a product. The results will be published in a book
aimed at helping practitioners apply usability engineering
cost-effectively throughout the product lifecycle.

Some of the questions the workshop will address are: How should users
be involved? Which tools or techniques should be selected? How can
multiple techniques be combined in an integrated usable package for use
throughout the product lifecycle? How should criteria and risks be
assessed? How can cost-benefit judgements be made?

Participants should be familiar with the state of the art in order to
provide insight into the categorisation of existing strategies,
techniques, and tools. To apply, submit a 3-5 page position paper
suitable for circulation to other participants.

Saturday and Sunday, 24-25 April

Continued progress in fielding truly usable systems will draw upon the
ideas of HCI experts across the world to build interfaces that are
usable by people of diverse cultural backgrounds.

The first cross-cultural workshop was held at CHI '92. In this workshop
participants will build a conceptual map that lays out cultural
differences in HCI. Additional goals are to provide a medium for
individual collaborations to emerge and to make concrete suggestions
for follow-on activities. Different cultures have different meeting
protocols. The "process" as well as the "product" of the workshop will
reflect these cultural differences.

Position statements should outline some aspect of the participant's
cultural perspective on HCI, and may be submitted to whichever of the
organisers may be most able to judge the value of the contribution. We
are especially interested in achieving participation from a set of
people spanning the major cultural perspectives on HCI.

Spatial Metaphors for User Interfaces
----------------------------------------------------------------------------
Werner Kuhn, Technical University Vienna 
Andrew U. Frank, Technical University Vienna

Saturday and Sunday, 24-25 April

Modern user interfaces are increasingly dependent on the realisation of
abstract operations in spatial metaphors. Familiar metaphors such as
desktops, navigation, rooms, museums, or perspective walls demonstrate
the crucial role of "spatialisation" in HCI. Virtual reality promises
user interfaces that rely heavily on human abilities to perform complex
motion and perception tasks. Our understanding of the role which
spatialisation plays in interaction is, however, still quite limited.

This workshop will bring together researchers and designers interested
in exploiting spatial metaphors for user interfaces. Participants will
review the structure and role of spatial metaphors in human cognition,
establish the properties of space and spatialisation in existing user
interfaces, and identify approaches to exploiting spatialisation in
user interface design. Applicants should have some familiarity with
work on metaphor in HCI, in cognitive science, or in both areas.

Exploratory Sequential Data Analysis in Practice
----------------------------------------------------------------------------
Penelope M. Sanderson, University of Illinois at Urbana-Champaign  
Carolanne Fisher, MAYA Design Group 
 
Saturday and Sunday, 24-25 April

Exploratory sequential data analysis (ESDA) is a working term coined to
cover a loose set of research- and design-oriented data analysis
activities based on time-stamped recorded data. The activities include
verbal protocol analysis, conversation analysis, interaction analysis,
behavioural observational studies, statistical sequential data
analysis, and some kinds of cognitive task analysis.

This workshop will bring together HCI colleagues engaged in ESDA to
investigate the varieties of practice that exist and to discuss the
development of a principled approach to ESDA. We will explore the
conceptual foundations of various techniques and clarify the advantages
and disadvantages of each for different research questions and types of
data.

Through problem solving exercises (with real data) led by recognised
authorities in the application of ESDA techniques to the HCI domain,
participants will develop a more principled approach to empirical
questions using ESDA.

Piyawadee "Noi" Sukaviriya, Georgia Institute of Technology  

Sunday, 25 April

The adaptation of human-computer interfaces to the needs of individual
users can improve user performance with interactive systems, but only
if users can understand and manage the adaptive behaviour. The goal of
this workshop is to explore possible dimensions of computer-aided
interface adaptation.

Position papers are sought from researchers with experience or interest
in adaptive systems which address user involvement (e.g., How much user
involvement is appropriate in the adaptation process? How much control
over adaptation do users want? How much can they maintain before
becoming confused?), understanding adaptive behaviour (e.g., How can
the system provide insight into adaptation mechanisms? How can the
system help users decide whether a system-proposed adaptation is
appropriate for them?), and interfaces to adaptation (e.g., How can
higher-level, task-oriented adaptations be supported? How much support
can be given for the adaptation of complex interfaces?).

Working With Users Throughout the Product Lifecycle: 
Nomadic Practice in User Centred Design
----------------------------------------------------------------------------
Michael J. Muller, US WEST Advanced Technologies  

Sunday, 25 April

This workshop proposes the concept of "nomadic practice in user centred
design" (Nomadic UCD). Nomadic UCD is a set of activities, approaches,
technologies, and theoretical perspectives that help practitioners to
work with users in the users' own work context. The goal is to analyse,
design, develop, test, and deliver products and services that fit into
the user's world-view and work-life.

Although a number of people are tacitly working in this area, we do so
within an overall practice that may also include fixed-location
laboratory methods, field methods that focus on the developers' world
or on the computer artifact, and involvement of the user during the
design phase rather than the full development lifecycle. This workshop
will focus on the nomadic aspects of UCD practice throughout the
product lifecycle.

To apply, submit a 3-5 page position paper covering any aspect of
activities, approaches, technologies, and/or theories of Nomadic UCD.

Friday and Saturday, 23-24 April

INTERCHI '93 will sponsor a two-day research symposium preceding the
regular conference. The purpose of the symposium is to provide
researchers with an opportunity to explore developing research issues
in greater depth and with a higher degree of interactivity than is
possible during the conference proper.  We invite researchers
throughout the international HCI community to participate by presenting
preliminary results and work in progress, or by contributing to the
pre-conference preparation work (e.g., preparing tutorial summaries or
developing benchmarking problems).

To facilitate informal discussion, the research symposium will be
limited to no more than 70 participants. Selections will be made on the
basis of brief (three-page) research summaries describing recent
activities and current interests and including a list of recent
research publications.

The deadline for application is 1 February 1993. E-mail submissions are
preferred.

The committee will respond to all applicants, and issue work
assignments to designated invitees by 26 February. Contact the
organiser for more information about the research symposium, or to
submit a proposal.

TUTORIALS	Sunday, 25 April                                       pg. 5
----------------------------------------------------------------------------

Tutorials, both full and half-day, will be offered on Sunday and
Monday, 25 and 26 April. They provide an opportunity to develop new
skills and knowledge through extended interaction with expert
instructors. Tutorials provide a bridge between what you know now and
what you need to know tomorrow.

The 29 tutorials available at INTERCHI '93 represent the leading edge
of current practice and the research advances that are changing the
future of human-computer interaction. Newcomers to the field will
especially appreciate the overview tutorial (7). Other introductory-
level tutorials deal with prototyping (11), multimedia (2, 26), 
film craft (17), virtual realities (21), help systems (14), and
evaluation methods (22).

Design process overviews are available at introductory, intermediate,
and advanced levels, respectively, in the tutorials on designing
graphical user interfaces (1), engineering usability in large
development organisations (16), and championing usability with limited
resources (15). Other design tutorials will address involving users in
participatory design (19), moving from observation to invention with
scenarios and story-boards (18), and integrating customer data in
contextual design (6). Practical design tutorials will address
effective visual design (9), metaphor (10), icon design (13), and
designing for GUI standards (29).

Those interested in how people work together may wish to try the
tutorials on electronic meetings (4) and collaborative learning (25).
You may also discover techniques for modelling interaction (5), and
interactive learning (20). Software developers will be especially
interested in tutorials on user interface tools (27), human factors in
software development (24), and information visualisation (12).
Management issues are addressed in tutorials on managing design (8) and
the business case for usability (23). Everyone may also want to
consider the tutorials on users with special needs (3) and the
consequences of the European Health and Safety Directive (28). Register
for your tutorials on page 31, taking care to avoid conflicts in
schedule.

	Annette Wagner, SunSoft, Inc.
	Bruce "Tog" Tognazzini, SunSoft, Inc.

	Full Day, Sunday 25 April 
	
	Objective: This tutorial will help the participant learn to
	build an effective design team and develop successful direct
	manipulation graphical interfaces in the real world. Along the
	way we will explode some common myths. Participants will gain a
	better understanding of the fundamentals of graphical interface
	design and how to apply those fundamentals.

	Content: This tutorial will begin with a discussion of the principles
	of graphical interfaces and the underlying assumptions about human
	nature on which they depend. We'll then look at how to relate this
	higher-level thinking about principles and assumptions back to the 
	real world. In the afternoon, we'll introduce techniques for building 
	an effective design team. We'll then work through the design of one 
	aspect of a software application to demonstrate how to make the best 
	decision possible given the constraints of a commercial product. This 
	tutorial will consist of interactive presentations interspersed with
	participative case studies and class exercises.
	
	Audience: This introductory-level to intermediate-level tutorial will
	focus on practical design for commercial products. It is oriented
	toward interface designers and others involved in the design of
	graphical interfaces.

	Instructors: Annette Wagner spent 11 years at Apple Computer, Inc. 
	working on the Lisa desktop and several versions of the Macintosh 
	Finder. She is currently a technical lead in the Human Interface 
	Engineering group at SunSoft, Inc. Bruce "Tog" Tognazzini has been 
	designing person-machine interfaces for more than 30 years. He began 
	the human interface effort at Apple Computer, Inc. and headed up both 
	the Apple II and Macintosh Human Interface Groups. He is currently a 
	member of the Human Interface Engineering group at SunSoft, Inc., 
	where he has launched a project to design and build a second 
	generation visual interface. Tog is the author of the popular human 
	interface book, Tog on Interface.

	fundamentals, tools, and methods of multimedia content
	authoring on a variety of hardware and software platforms.

	Content: This tutorial will provide an overview of multimedia
	authoring issues and describe common problems and useful
	techniques. Multimedia content development and software
	analysis techniques will be demonstrated on the Macintosh with
	the MacroMind Director authoring environment. Multimedia
	development issues for PCUs will be introduced using the
	Authorware Professional authoring tool. Finally, multimedia
	capabilities for the UNIX workstation environment will be
	addressed by an introduction to GainMomentum. GainMomentum is
	an object-based multimedia development and deployment system on
	Sun workstations, useful for building information systems of
	varying size and complexity across OSF/Motif, OPEN LOOK, and
	Microsoft Windows environments.

	Audience: This introductory-level tutorial is intended for user
	interface designers who focus on multimedia production. It will

17	Film Craft in User Interface Design
	---------------------------------------------------------------------
	Emilie Young, Emvision and Visual Magic
	Chuck Clanton, Aratar and Visual Magic
	
	Full Day, Monday 26 April 

	Objective: This tutorial will help participants apply knowledge
	from the communication crafts of film and animation to user
	interface design. The tutorial covers general principles but
	concentrates on the practical details of the craft.
	Participants will learn to critically evaluate films and use
	that skill to see user interfaces in a new light.

	Content: This tutorial will introduce classic cinematic
	techniques that can be exploited in user interface design. With
	mere shadows seen through a narrow window, filmmakers engage us
	in a world of their own making without disturbing our awareness
	by its technical apparatus.  They are masters at using pictures
	and sounds to communicate, entertain, evoke feelings, and
	manipulate our sense of space and time.  Ninety years of
	filmmaking and animation have created a rich store of knowledge
	barely tapped by current human-computer interfaces.  Multimedia
	on graphical workstations only whets our appetite for knowledge

	Objective: This tutorial has been prepared in response to a
	Council Directive of the European Commission (90/270/EEC, 29
	May 1990) requiring the principles of software ergonomics to be
	applied in commercial product development from 1993 onward. The
	tutorial will provide a strategic and methodological overview
	of ergonomic quality assurance and conformance testing for
	international standards. 

	Content: This tutorial will offer an interpretation of the
	strategic and methodological consequences of the Health and
	Safety Directive.  Examples will be used to demonstrate how to
	elicit essential requirements, to determine verifiable criteria
	of usability, and to test products (prototypes) for compliance
	with standards. The specifics of software-ergonomic quality
	assurance and management will be interpreted with reference to
	well-known requirements for in-house software quality systems.
	Since the Directive also requires designers to evaluate
	attributes of the product (or the context of use) which may
	induce "mental stress," a strategy will be outlined on how to
	identify critical stress situations by means of objective and
	subjective measures.  Participants will receive a booklet
	providing guidelines for compliance in software development
	organisations.

	Audience: This introductory-level tutorial will be most
	suitable for software designers, quality engineers, and
	managers who want to concentrate their effort on a
	cost-effective endeavour. No previous experience in software
	ergonomics will be required.

	Instructors: Wolfgang Dzida and Albert Arnold are senior
	scientists at GMD and Delft University of Technology,
	respectively. They contributed to the development of
	international standards and published in evaluation
	methodology. Marion Wiethoff is also a senior scientist at TU
	Delft where she is involved in the physiology and psychology of
	workload and stress. The instructors cooperated in a
	Dutch/German project to develop a guide to ergonomic quality
	assurance of software.

----------------------------------------------------------------------------

The INTERCHI '93 Technical Programme will feature the state-of-the-art
in HCI. Presentations of work from around the world will reflect both
traditional views of HCI and a new perspective, in which:

- computing is present everywhere, not only via workstations,
- communication is low-cost and	high-speed,
- new input and output devices go beyond keyboards and displays,
- applications encompass the casual and the critical, work and play, 
  and art and science,
- isolated perspectives are integrated, 
- users are recognised as part of a social, physical, and technical 
  environment,
- the human process of design and its supporting tools are as important 
  as the resulting products.

In addition to papers, panels, overviews, demonstrations, and videos,
the technical programme will feature a number of special events. Alan
F. Newell's opening plenary address will focus on designing for all
people.  Daily talks by three experts will offer personal perspectives
on the impact of HCI in the lives of ordinary people in specific areas:
Frank P. Carrubba on consumer electronics, James Alty on music, and
Jean-Claude Wanner on cockpit design. An informal debate will explore
the role of the European ESPRIT Programme as a channel for advancing
the industrialisation of HCI. Finally, the closing plenary address by
Michael Chanowski will offer new insights on multimedia. We are
confident you will enjoy the entire INTERCHI '93 Technical Programme.

The University of Dundee, Scotland

CHI for Everyone

CHI research and development often seems to be based on the assumption
that the user is an intelligent, motivated, physically able twenty-five
year old who is operating in an ideal environment. This lecture
questions whether this is an accurate representation of the use of
computers in real situations. It is suggested that we should extend our
vision to include both extra-ordinary users, such as those with a
physical, sensory, or mental disability (or even just natural aging)
and extra-ordinary situations, such as excessive workload, high stress
level, or environmental disturbance (e.g., smoke and noise). Parallels
between ordinary and extraordinary situations will be drawn and the
significant advantages of taking the broader view will be described.

Closing Plenary Address

Michael M. Chanowski Founder, Computer Assisted Televideo Benelux
BSO/Origin, Schellinkhout-Holland

The Multimedia Myth: Of Mice and Men

In addition to being difficult to understand and use, many of today's
dedicated applications neglect the capacity of the medium for artistry
and inspiration. This talk will consider human-machine relations from a
"lateral" perspective. Instead of teaching people to become more
skilled computer users, with a deeper understanding of the architecture
and idiosyncrasies of the machine, the lateral approach focuses on
teaching computers to better address the characteristics of the user as
a human being. A number of psychological factors affect the user's
perception of the machine as friend or foe. This address will examine
the consequences of human psychology for software and hardware design,
along with the widely-acclaimed potential of multimedia for addressing
the problems seen in current-generation systems.

Biography

Michael M. Chanowski is founder of BSO/CAT, the multimedia research and
training centre of BSO/Origin, a large HCI consultancy in
organisational design and management. Mr. Chanowski's background is in
film production and direction, animation technology and computer
science. At Philips, he was involved in the design of the first
laserdisc player and experimented with interactive systems resulting in
the first interactive laserdisc in 1972. Since then, he has made
important contributions in the fields of image processing, retrieval
technologies, and authoring tools for multimedia database systems, as
well as in advanced simulation technology for the European Space
Programme.  More recently he has collaborated with Delft University of
Technology on research into compression techniques, machine interpreted
remote sensing, fuzzy and neural experiments, and the design of
interrogated user interfaces.  


----------------------------------------------------------------------------
ADDITIONAL CONFERENCE ACTIVITIES                                   pg. 22-23
----------------------------------------------------------------------------

Additional conference activities taking place throughout the week will
include the Formal and Informal Video Programmes, Informal
Demonstrations, the Interactive Experience, Exhibits, Special Interest
Groups (SIG's), the Student Volunteer Programme, and the Doctoral
Consortium. Special events such as the Informal Debate and the daily
Perspectives on HCI talks are also featured here.

Formal Video Programme

Video submissions are increasingly important as an asynchronous
component of the technical programme. The formal video programme at
INTERCHI '93 will be shown continuously throughout the conference. It
has been assembled from submissions by leading researchers and
practitioners around the world, and will include both new work and
important recent work that merits a repeat showing to a wider audience.
The programme will serve as a showcase of innovative HCI design,
methodology, and novel interaction techniques that will contain
something of interest for all conference participants. The formal video
programme will be organised into five tracks:

- user interface design, tools and techniques, and novel 
  modes of interaction,
- speech and natural language,
- design rationale,
- information visualisation,
- future scenarios.

Informal Videos

All conference participants are invited to bring videotapes (VHS only,
in PAL or NTSC format) showing recent work for viewing in the informal
video area. Suitable videos might include submissions that missed the
formal video deadline, videos that were too long for the formal
programme, or videos deemed to be of special or peripheral interest.
Please be certain to mark your tape clearly with your name and address
and the title of the tape before leaving it at the informal video area.
We will do our best to safeguard the tapes, but unfortunately we cannot
be responsible for any lost or damaged material.

Informal Demonstrations

In addition to the formal demonstration programme, space will be
provided for informal demonstrations of interesting work in progress or
of work completed too late to make the deadlines for the formal
programme. Participants are encouraged to bring their own hardware -
particularly if any special software or peripherals are required. The
conference will provide some of the more common platforms, but
prospective demonstrators should verify the availability of the system
you require. Although informal demonstrations can be arranged in
advance, they are normally scheduled at the conference itself. Sign up
sheets will be available at the INTERCHI '93 information booth.

advance, contact:

Interactive Experience

The Interactive Experience is that part of the INTERCHI '93 programme
that most actively stresses interaction between people and innovative
interface technologies such as speech, music, video, gesture,
computer-clothing, eye-tracking, and collaboration. Participants are
free to wander through the Interactive Experience exhibit area and
explore the installations that interest them. Many accommodate more
than one participant at a time and all emphasise a "hands-on" approach
that encourages participants to become active participants in the
exhibit and is the most important aspect of the Interactive
Experience.

Exhibits

The INTERCHI '93 exhibits feature the latest in HCI-oriented products
and services from commercial vendors, institutions, and publishers. The
exhibits provide an opportunity to meet with technical representatives
from the exhibiting companies and to observe a broad spectrum of new
and emerging products.

Special Interest Groups (SIG's)

Special Interest Groups (SIG's) are informal meetings where small
groups can discuss specific topics of common interest as part of the
INTERCHI '93 technical programme. Possible topics include new research
areas, professional issues, interdisciplinary subjects, cultural
diversity, industrial relations, and social implications of computing.
SIG's promoting contacts between new and existing HCI cultures in
different national or regional areas are especially encouraged. Anyone
can organise a SIG, and anyone can attend (i.e., you need not be a
"member" of these informal groups). Conference space will be provided
for the 90-minute meetings. Participants are encouraged to organise
SIG's in advance; these will be announced in the final conference
programme. SIG proposals will also be accepted at the conference and
announced on-site, on a space-available basis.

To be considered for inclusion in the final programme, your SIG proposal
must be received by 15 January 1993.

SIG proposals should include the standard cover sheet (see INTERCHI '93
Call for Participation) and a one-page proposal providing a short
description of the topic along with the names of the organisers and any
planned participants.

of Ph.D. candidates who have completed their dissertation proposals and
who have been invited to discuss their work in a small closed session.

Faculty:

Thomas R.G. Green, Chair, MRC Applied Psychology Unit 
Phyllis Reisner, Integrated Systems Solutions Corporation, IBM

Student Volunteer Programme

Graduate and undergraduate students from throughout the world are
invited to participate in the INTERCHI '93 student volunteer programme.
Student volunteers fill an essential role by providing part-time
assistance with the day-to-day operation of the conference. The
benefits of becoming a student volunteer are many. In addition to a
complimentary conference registration, reduced-rate housing, and a free
tutorial, student volunteers have the opportunity to experience the
conference "behind the scenes," to establish lasting friendships with
other students, and to learn more about favourite topics in HCI by
interacting closely with the field's leading experts.

Informal Debate

16:00 Tuesday, 27 April

The European ESPRIT Programme is a major EC (European Community)
initiative aimed at advancing the industrialisation of information
technology. The role of this programme in the industrialisation of HCI
will be discussed in a special debate format featuring prominent
members of the academic and industrial research communities.


Perspectives on HCI

The Evolving Consumer Market: We Have to Sell It!
Dr. Frank P. Carrubba, Philips Electronics N.V.

14:30 Tuesday, 27 April

How are we to adapt the digital technologies available today to meet
the evolving wants and needs of consumers in a rapidly changing world,
in the emerging European market, and in the global village? What
technologies are on the horizon that might interest tomorrow's
consumers? These are major challenges confronting all consumer
electronics manufacturers. This presentation will offer a personal
perspective on these issues and the role of HCI research and
development in answering these challenges.

Human-Computer Interaction and Music: Squaring the Circle?
Professor James Alty, Loughborough University of Technology

09:00 Wednesday, 28 April

Better interface techniques have contributed significantly to the music
creation process. No self-respecting composer can now function
effectively without their favourite computer-based music editor,
sequencer, and synthesiser. Graphical interfaces add a spatial
dimension to the compositional process. The aural dimension offered by
music has, however, been largely ignored in interface design. The human
ear is capable of receiving and interpreting exceedingly complex
musical sounds, but this capability has never really been exploited.
Why is this, and how might we take advantage of this rich channel of
communication?

>From Manual Control to Information Management: HCI in the Cockpit
Jean-Claude Wanner, Consultant

09:00 Thursday, 29 April

The new generation of "glass cockpit" aircraft cannot be practically
flown when all computers fail; some are essential for safety. What,
then, is the role of the crew? Who is the boss: the pilot or the
computer? How should the interfaces between people and machines be
designed to help the crew manage the flight safely? The study of recent
incidents and accidents gives the aviation community both some answers
to these two fundamental questions and rules to guide design.

SOCIAL EVENTS AND CONFERENCE SERVICES                                 pg. 24
----------------------------------------------------------------------------

The INTERCHI '93 conference is more than just the leading technical
forum for the HCI profession. The conference also provides an excellent
opportunity for networking and renewing friendships with colleagues
from around the world.

Conference Reception

19:30 - 21:00 Tuesday, 27 April
Beurs van Berlage, Amsterdam

The Mayor and Aldermen of Amsterdam will join the conference committee
in hosting the conference reception on Tuesday evening. Hors d'oeuvres
and drinks will be served at the Beurs van Berlage, a beautiful
structure built between 1898 and 1903 by the famous Dutch architect, 
H.P. Berlage.

Sample delicious international appetisers as you enjoy the company of
friends and colleagues in this lovely social setting. Additional

----------------------------------------------------------------------------
VISITING AMSTERDAM                                                 pg. 26-27
----------------------------------------------------------------------------

Amsterdam is among the most beautiful cities of Europe. Renowned for
its fascinating architecture and concentric rings of canals spanned by
hundreds of historic bridges, Amsterdam offers all the benefits of a
large city with few of the disadvantages. Here you will find world
class museums, restaurants, cafes, cinemas, and theatres. Participants
can enjoy the city by exploring the many shopping opportunities,
keeping pace with the energetic nightlife, or simply appreciating the
scenic beauty of one of Europe's oldest major cities.

Museums and Historic Sites

Amsterdam is home to several museums of international reputation,
including the Stedelijk museum of modern art, the Van Gogh Museum, and
the Rijksmuseum, which is famous for its large collection of
Rembrandts. Sites of historic interest include the Old Church (Oude
Kerk), and the Anne Frank House, where the author of the famous diaries
hid with her family during the Second World War. See the map on the
next page for additional points of interest.

Canals

Thanks to the extensive network of canals, traffic is largely confined
to a few main roads, leaving large areas of the city as oases of quiet
beauty. Frequent tour boat excursions provide unique sightseeing
opportunities. There is even a "canal taxi" that stops at several
museums.

Tulip Season

Flower-loving participants will be happy to note that INTERCHI '93
takes place in the midst of the tulip season, so a trip to the bulb
fields and the nearby Keukenhof gardens should be especially
worthwhile. A beautiful daily flower market on the Singel canal is a
perennial favourite.

Queen's Day

The Friday after the conference (30 April) is Queen's Day - Amsterdam's
most important holiday. On this day, commemorating the birthday of the
Queen, the entire city is transformed into a giant open-air market and
launches a celebration you won't want to miss. In fact, travel on
Friday will be quite difficult, so plan to stay and enjoy the festive
atmosphere.

Language and Communication

Amsterdam is an international crossroads and the Dutch are a
multilingual people - 92% speak fluent English. Conference participants
should also have no trouble communicating in French, German, or of
course, Dutch! When joining a gathering, either business or social,
please keep in mind that it is usual for newcomers to introduce
themselves. Do not wait to be introduced as this is unlikely to
happen.

Currency

The Dutch unit of currency is the guilder (Dfl.). The currency was
formerly known as the Dutch florin, hence the abbreviation. Bank notes
are issued in denominations of 10, 25, 50, 100, 250, and 1,000
guilders. Coins are circulated in 5 cent, 10 cent, 25 cent, 1 guilder,
2.5 guilder, and 5 guilder pieces. One guilder equals 100 cents.

Climate

Amsterdam weather at the end of April can be unpredictable. Springtime
weather is usually sunny, with intermittent rain showers. Daytime
temperatures normally reach a maximum of 15-20 C (60-68 F), but
evenings can be cold. Bring some warm clothing and a raincoat.

Passports

Get your passport now! Conference participants from countries other
than the Netherlands will need a passport to attend INTERCHI '93. Visas
will not be required for travelers from the EC (European Community) or
North America.

Transport to and from the Airport

Buses and taxis are available for transport to and from the airport,
but conference participants may want to take advantage of the excellent
train service between the airport and the centre of town. Trains leave
the airport every 15 minutes for Amsterdam Central Station (C.S.) or
RAI Station, where trams are available to take you to your hotel. Taxis
are also always available at Central Station. Please note that taxis
are never hailed in the Netherlands, but taken from one of the many
taxi stands throughout the city. Train fare to the town centre is
approximately Dfl. 5 ($3 US).

Please Note: Public transport from the city centre to the airport will
not be easily accessible on Queen's Day (30 April). If you wish to
leave Amsterdam immediately after the conference, you are strongly
encouraged to make travel arrangements for Thursday evening or wait
until Saturday to leave.

Getting to the RAI

INTERCHI '93 will take place at the International RAI Congress Centre
located on Europaplein on the outskirts of the city centre. Amsterdam's
excellent public transport network provides fast, easy and inexpensive
transportation to the RAI from any of the conference hotels. Direct
trams and express trams run between the RAI and the centre of town
every few minutes.

Conference Hotels

The RAI Hotel Service is coordinating conference housing. All
conference hotels offer private baths and convenient access to public
transportation to the RAI. To help you make your hotel selection, the
conference hotels have been classified by geographic location:

Zone 1	within Amsterdam city centre
Zone 2	within walking distance of the RAI
Zone 3	near the RAI
Zone 4	near Schiphol Airport

Of Special Note: Typically only Deluxe and Category A hotels provide
parking facilities, non-smoking rooms or floors, or special access for
disabled persons.

For information on extremely low-cost housing (private baths are not
generally available), you may contact the INTERCHI '93 European Office
at the address listed on page 24.

	Deluxe				Zone

	Golden Tulip Barbizon Centre	1

TRANSPORTATION                                                        pg. 28
----------------------------------------------------------------------------

Air travel to Amsterdam can be arranged through the conference
carriers, KLM Royal Dutch Air Lines or Delta Air Lines. Both carriers
fly into Schiphol International Airport, located about 18 kilometres
southwest of the city.  Currency exchange banks are available in both
the arrival and departure halls.

Public Transport

A "strippen kaart" is used to pay fares for all public transport within
Amsterdam. The fare is one strip per travelling zone plus one
additional strip per ride. Journeys between the RAI and the city centre
are 2 zones, and therefore 3 strips. The cards are stamped in a machine
at the entrance to the metro or inside the tram. A card with 15 strips
can be purchased for approximately Dfl. 10 ($5.50 US). Single journey
cards can be purchased from tram drivers, but they are 50% more
expensive. These cards cannot be used for transport to and from the
airport.

Weekly Transit Passes

Weekly passes for the tram or metro are available from INTERCHI '93 at
a cost of Dfl. 30 ($17 US), which may provide a substantial savings
depending on the amount of travelling you do in Amsterdam. To order a
weekly pass, mark the appropriate box on the back of the conference
registration form (page 32).

Bicycles and Cars

The central city is fairly compact and most points of interest are
within easy walking or cycling distance. Amsterdam's network of bicycle
paths (often indicated by pink pavement) makes cycling here a real
pleasure and a viable transportation alternative. Bicycles can be hired
throughout the city. Pedestrians are advised to avoid walking on bike
paths, as bicyclists have the right of way.

Cars can be hired at the airport, but their use within the city is
strongly discouraged. Traffic is usually heavy enough to make cars a
much slower form of transport than express trams, trams, or even
bicycles. There is a severe shortage of parking in Amsterdam and most
hotels do not provide parking facilities. The RAI has several
exhibition halls in use during INTERCHI '93 and does not expect to have
sufficient parking.


KLM Royal Dutch Airlines

KLM Royal Dutch Airlines is the official carrier for INTERCHI '93. KLM
is also a corporate sponsor of the conference.

Unrestricted Fares

In addition to its usual service to Amsterdam from all over the world,
KLM is offering unrestricted fares for international flights to the
conference from the United States. KLM flies nonstop to Amsterdam  from

----------------------------------------------------------------------------

Founded in 1947, the Association for Computing Machinery (ACM) is the
largest and oldest educational and scientific computer organization in
the industry today.  ACM's name reflects the concerns of its founders
(i.e., machinery), but ACM's vitality stems from its members - their
ideas and experiences. ACM is a society of individuals, a living
vehicle for the continuity of professional standards and traditions.
>From a dedicated group of 78, ACM is now 83,000 strong, with 34 special
interest groups (SIGs), including SIGCHI (Special Interest Group for
Computer and Human Interaction), and more than 600 chapters and student
chapters.

The scope of SIGCHI consists of the study of the human-computer
interaction process and includes research and development efforts
leading to the design and evaluation of user interfaces. The focus of
SIGCHI is on how people communicate and interact with computer systems.
SIGCHI serves as a forum for the exchange of ideas among computer
scientists, human factors scientists, psychologists, social scientists,
systems designers and end users. Over 5,000 professionals work together
toward common goals and objectives.

Membership applications for ACM/SIGCHI can be obtained by contacting
the ACM Headquarters via electronic mail at ACMHELP@ACMVM.bitnet or by
calling +1 212 626 0500.
