About the Panel Discussion
At June's CapCHI meeting, several individuals and groups from the Ottawa
area who attended CHI 99 conference on Human Factors in Computing Systems
in Pittsburgh presented short conference reviews. Some of the topics discussed
at the conference included: What HCI is and why is it important? Globalizing
Usability Engineering; Visual Design for E-Commerce and Performance Tools;
CSCW; Distance Learning; and many others.
CHI 99, "The CHI is the Limit", poses the questions:
What are the limiting factors to the success of interactive systems? How
can we enable users to overcome those limits? What techniques and methodologies
do we have for identifying and transcending limitations? And just how
far can we push those limits?

Designing for Adaptation: Ecological Interface Design
May 11, 1999
About the Speaker
Kim J. Vicente is professor of Mechanical &
Industrial Engineering and of Biomedical Engineering at the University
of Toronto, and director of the Cognitive Engineering Laboratory
there. He received his PhD in mecanical engineering from the University
of Illinois at Urbana-Champaign in 1991. He has recently completed the
first text book on cognitive work analysis, entitled, "Cognitive Work
Analysis: Toward Safe, Productive, and Healthy Computer-based Work", and
published by Lawrence Erlbaum Associates.
About the Talk
In the global, knowledge-based economy, there is an increasing need
for workers to adapt to change and novelty. Ecological interface design
(EID) is a theoretical framework for designing
interfaces for complex sociotechnical systems that addresses this
need. This modelling effort tries to identify both the low-level physical
constraints and the higher-level functional constraints
associated with the work domain. EID then tries to present a visualization
of that information in such a way as to take advantage of the power
of human perceptual-motor skills.
An example application of EID
for a thermal-hydraulic process control microworld was presented. In addition,
the research that has been conducted
on EID in other application domains (e.g., hypertext information retrieval,
aviation, medicine, nuclear power) was summarized.

JavaScript for People with Better Things to Do
March 19, 1999
About the Speaker
Michael Kurtz received his degree in Industrial
Design from Carleton University, which he followed up with a Masters in
Ergonomics at Loughborough University, UK. Self-employed as a product
design consultant, he has worked with the Corporate Design group since
1991, both in Ottawa and in Harlow, UK. Michael's current role in CDG
is as an Interaction Designer working on applications ranging from eCommerce
to physical object - digital artifact interrelation.
About the Talk
JavaScript is an easy to use,
yet powerful browser scripting
language. It can be used to bring new levels of interaction to your web
sites, and makes an excellent tool for doing rapid
prototyping of product interfaces. The main benefits are that it's
fast, flexible, cross platform and requires no plug-ins. This short workshop
was intended to provide the user with some basic knowledge of the structure
and principles of JavaScript.
Topics covered included:
- JavaScript basics
- Rollovers
- Multiple rollover effects
- Controlling Windows
- Controlling Frames
- An introduction to Cookies.
What did you need to know? - A basic knowledge of HTML.....um....and
the ability to type.

Ethnographic Methods in System Design
February 17, 1999
About the Speaker
Robert MacLeod is a Ph.D. student in anthropology
from UBC who is currently doing his doctoral fieldwork in a lab at Nortel.
He is interested in understanding the importance of social context in
accounting for how groups of people work together in complex situations
involving a high degree of human-computer interaction. He is particularly
interested in the role that communication plays in defining the character
of such interaction. He has a B.A. and M.A. in Anthropology from Carleton
University.
About the Talk
Because of the sophistication of both computer
technology and system design
there is a growing need to incorporate
the social sciences in the design process. Anthropology,
and ethnographic methods are
increasingly being applied to this process with great success. Robert
described the importance of using ethnographic methods for designing
interfaces and discussed the details of such a methodology. Robert
hopes that by explaining the relevance of ethnography, designers will
be able to apply a sensitivity to general
social dynamics to their work even if it is not possible to incorporate
a truly anthropological component.

Introduction to Cascading Style Sheets
January 19, 1999
About the Speaker
Roger Chang is a senior user interface designer
and Web UI prime at Cognos Inc., a leading supplier
of business intelligence software. He is currently working on designing
HTML, DHTML and Java UI's for enterprise reporting solutions. Roger's
previous work experience includes usability testing, IT consulting and
web administration. He holds a B.Sc. in Psychology from Carleton University.
About the Talk
Cascading Style Sheets (CSS)
provide a technology that enables designers to efficiently create compelling
and dynamic web content. Roger
provided an overview of the CSS specifications
recommended by the W3C and demonstrated the development of simple
CSS applications using Allaire Homesite
and Macromedia Dreamweaver.
The aim of the talk was to empower web designers with practical
CSS knowledge and skills that they may immediately apply to facilitate
the creation of browser based user interfaces.

Workshop: Improvising the Future
November 18, 1998
About the Speaker
Michael Kurtz received his degree in Industrial
Design from Carleton University, which he followed up with a Masters in
Ergonomics at Loughborough University, UK. Self-employed as a product
design consultant, he has worked with the Corporate Design group since
1991, both in Ottawa and in Harlow, UK. Michael's current role in CDG
is as an Interaction Designer working on applications ranging from eCommerce
to physical object - digital artifact interrelation.
About the Talk
How do you take a user-centred approach
to designing novel interfaces? How do you design products which address
future needs, which users certainly cannot articulate in the here-and-now?
How can you use techniques from improvisational
theatre to help design interfaces for new products?
We sure found out, in this 2-hour,
highly interactive workshop, where we all experienced how role-playing
and 'Improv' techniques could help us tackle these thorny issues, and
bring a little fun into our lives at the same time!

UI Prototyping Tools - Why, Which and When?
October 16, 1998
About the Speaker
Dr. Roy Ballantine has a background in Cognitive
Psychology (with an emphasis on Visual Information Processing) and has
received degrees from the University of Alberta; the University of South
Africa; and the University of Cape Town. He has worked in UI design for
16 years, recently at Nortel and now at Cognos.
Roy teaches a course in prototyping at Carleton University and uses
prototypes as an integral part of his UI design method. He takes the position
that prototyping is a tool to de-risk elements of an interface as quickly
possible and that elaborate and hi-fidelity prototypes are not necessary
for most purposes.
About the Talk
Knowing which prototyping tool to use and when is a challenge for many
people, even for a seasoned UI designer. In this presentation, Roy spoke
briefly about general UI prototyping principles and provided tips for
success based on his personal experiences. During this talk, five or six
useful prototyping tools were demonstrated with their particular strengths
and weaknesses described. The tools reviewed in more detail included:
- Paper Prototyping
- Visual Basic (Windows)
- Delphi (Windows)
- MacroMedia Director (Mac & Windows)
- Visual Café (Windows & Mac)
- MetaCard (Unix, Windows, Mac) - With side discussion of HyperCard
and SuperCard (Mac)

The Importance of Studying Work: Software Maintenance and Search
September 17, 1998
About the Speaker
Dr. Janice Singer joined the Software
Engineering Group of the National
Research Council in 1995. She currently leads the Empirical Approaches
to the Study of Software Engineering (EASSE) group. The focus of her projects
is to understand, from a cognitive and human computer interaction perspective,
how software engineering is done, and from this understanding lead the
design of tools for this unique user group. Dr. Singer received her Ph.D.
in Cognitive Psychology from the University of Pittsburgh and her B.A.
in Cognitive Science from UCSD. For graduate studies, she examined the
relationship between perception and cognition as the foundation for early
mathematical concepts. During graduate school summers, she worked for
IBM Yorktown Heights Research Center with John Carroll doing research
in HCI. She was the original designer of the View-Matcher. She also worked
summers at Xerox PARC in the Institute for Research on Learning looking
at CSCW and situated cognition. Before graduate school, Dr. Singer worked
at Tektronix doing among other things HCI and Smalltalk programming on
the Tek 4401.
About the Talk
This talk discussed experiences studying the work practices of professional
software engineers with the goal of designing tools that enhance, rather
than displace or replace, these work practices. The rationale being that
the tools we build will actually be used because they have been created
to mesh with existing behaviour.
Reasons for following this approach were presented, along with description
of some details of NRC approach such as the discovery of work patterns,
and the use of synchronized shadowing. Dr. Janice Singer outlined several
studies currently being conducted in a large telecommunications company
and talked about how these studies have influenced the design of a software
engineering exploration environment.
