Spring 1994
A look at some of CICSR
members' work with industry,
including Hughes and Motorola
■ Collaboration with industry is one of the
main goals of CICSR, and it's working. At
any given time, several CICSR researchers
are at work on an industry-sponsored
project, some out at the company site.
One example is the work Jeff Joyce is
doing at Hughes Aircraft of Canada in
Richmond. Since late 1989, Hughes has
been at work on a $400 million contract to
develop a new air traffic control system for
Canada called CAATS. Hughes currently
has some 400 people at work on what is

■ This Spring is being ushered in with a
flourishing of CICSR research activity.
Since moving into the new CICSR/CS
Building last Fall, CICSR researchers
have expanded their programs and
collaborations dramatically.
New liaisons have been formed with
industrial partners and academics at
other institutions, facilitated by the
research space available and the new
funding mechanisms from NSERC and
the B.C. Advanced Systems Institute,
for example. Some of these are highlighted in this issue of the CICSR
newsletter, including industrial collaboration projects between CICSR researchers and Hughes Aircraft and
CICSR is also expanding its links with
other academic disciplines, in particular
with the Faculties of Education (to
pursue work on the E-GEMS project)
and Commerce (to develop Meeting
Place software). Both collaborative
projects are described in detail in this
All the speakers for next year's
Distinguished Lecture Series are now
confirmed. The series will focus on
human-computer interaction, a topic of
widespread interest among researchers
in group dynamics and decision support
systems for business use, and multimedia researchers in education and
computer science. The series promises
to provide a fascinating look at how we
will interact with computers, both
individually and in groups, in the
future. ■

reputed to be the largest software project in
Canada. Under the Transport Canada
contract, Hughes has been given the job to
provide Canada with the world's most
advanced air traffic control system. The
project is a major challenge, but the skills
developed by the Hughes team in Richmond have already been sought after by
other countries seeking state-of-the-art air
traffic control systems.
Joyce, a member of the Department of
Computer Science at UBC, has been
working half-time at Hughes since October
to investigate possible applications of
formal specification techniques to selected
aspects of CAATS.
On any complex software project, a series
of specifications are written outlining what
the software is supposed to do. Once the
developer and client agree on the specs, the
work proceeds. In the case of CAATS,
there is a whole bookcase full of requirement specifications generated. For each
specification, code must be written and
tested against the specifications. The task is
complex, and Joyce believes, lends itself
well to formal methods, his main area of
Joyce, with the help of several graduate and
post-doctoral students, is rewriting some of
the specifications in mathematical language
that lends itself to formal methods, but is
also readable by people who are not
mathematicians. The reason for doing this
is that math is a far more precise language
than English. Another advantage, and
fodder for more research, is that math
ematical specifications could be used to
automatically generate test cases.
Currently, developers test their software
against the specifications by generating test
cases for every possible scenario specified,
and then testing the software against these
cases. However, this method can be
somewhat error-prone, especially for very
complex specifications. As well, if the
specifications change, re-doing the relevant
test cases can pose quite a challenge.
"At this point, using formal methods to
write specifications is an exploratory idea,"
said Joyce. It may or may not be implemented as part of the CAATS project.
Joyce's goal is to develop a method of
writing specifications that will mean less
overall effort and better results for the
software development team. He is keeping
his approach general enough to be applicable to any software project.
In Hughes' case, Joyce is retrofitting an
existing project, and it may not be appropriate to rewrite all the existing specifications
into mathematical language. But he plans to
take what he's learned, and possibly apply
it in future Hughes projects or to the
software development of other B.C.
companies. Both he and the Hughes team
will have learned from the experience. ■ CICSR research talents in demand at Motorola
UBC Electrical Engineering is
a valued source of knowledge
and talent for Motorola.
■ The UBC Department of Electrical
Engineering is no stranger to Motorola
Canada. At its Richmond office, the
international provider of wireless communications and electronic equipment, employs
many of the department's alumni, and
always seems to have one or more faculty at
work on various research projects.
"The Electrical Engineering Department is
an excellent bed of knowledge for us," said
Bill Cooksley, director of Motorola's
Advanced Radiodata Research Centre. He
oversees the research agenda at Motorola's
Richmond office, and arranges for outside
researchers to fill gaps if needed.
Assistant professor Samir Kallel completed
a study in the past year for Motorola
entitled RD-LAP Combining ARQ Schemes:
How to enhance and improve the protocol.
Basically Kallel was interested in determining how code-combining can be incorporated into the RD-LAP communications
protocol, and in quantifying its effect on
performance. Using the existing protocol,
an entire packet is discarded if it contains
errors, even if some useful information was
transmitted. Kallel looked at ways for the
system to understand it received good
information as well as some jumbled data,
to distinguish between the two, and request
that only the damaged data be re-sent. For
example, if ten packets of information are
sent as part of a transmission, and all but
one are error-free, Kallel would like the
system to be able to send back a message
requesting a re-send of the damaged packet
only, not the whole works.
This research has the potential to dramatically increase wireless communications
efficiency, but it's a study for the future,
according to Cooksley. If what Kallel is
doing appears to work well, it may be
incorporated in Motorola products of the
future. In general, Motorola tends to use
university researchers for long-term
projects, said Cooksley, because they have
a greater opportunity than Motorola's
engineers to focus on specific areas of
technology, but can't always react fast
enough to work on time-sensitive projects.
Cyril Leung, another member of the
Electrical Engineering Department, has
worked on research for Motorola in the
past, and is now employed at Motorola on a
research project about which Motorola is
CICSR researchers are studying issues that will help in the development of the next generation of portable communications devices,
including future generations of the Motorola personal data communicator (above).
currently not releasing information. Leung's
past project involved providing his opinion
on Motorola's analysis of future high-
capacity wireless networks. Some of the
resulting paper, a joint effort between
Leung and Motorola's research staff, may
be published in the future.
Victor Leung of the Electrical Engineering
Department has also completed research for
Motorola. The project was jointly sponsored
by B.C. Tel Mobility Cellular, Motorola
and Science Council of B.C.'s Technology
B.C. program. The title of the resulting
study is, "Integrating Packet-Switched Data
Service to Circuit-Switched Service in
Cellular Mobile Radio Networks."
The research concerns the new technology
dubbed CDPD (Cellular Digital Packet
Data), which will enable digital data
communications over cellular networks. A
simple application of this technology is the
sending of faxes from laptop computers.
Cooksley notes there are several challenges
in relation to this technology. Leung's work
involved looking at performance issues, and
studying how the technology will work in
the real world once it is deployed.
"We don't have the bodies here to look at
all the issues we want to study," said
Cooksley. So he determines which projects
he should hand off to be tackled by outside
researchers, who are often CICSR members. "It's a slow process to determine
which projects are useful to both Motorola
and UBC, but we envision more projects in
the next six months."
Cooksley said the advantages of using
CICSR researchers in conjunction with
Motorola's internal research staff is that it
provides the company with a different
perspective, and provides access to a talent
pool consisting not only of faculty researchers, but also students who may go on to
work at Motorola after graduation. The
relationship also enables Motorola to invest
in longer-term research that may not be
applied until several years down the road.
Being a product-oriented company,
Motorola can't afford to puts its own
engineering staff to work on the longer-
term issues, said Cooksley.
The major drawback to working with
university staff is the issue of intellectual
property ownership, according to Cooksley.
University policy is to retain ownership of
the work of its staff, and license the
technology out to companies. This arrangement might work for some technologies, but
companies prefer to own key technologies
outright. In Motorola's case, the issue is
side-stepped by having only staff members
work in key research.
Overall, the advantages outweigh the
drawbacks, which is why Cooksley expects
more CICSR and Motorola collaboration in
the future. He adds that sabbaticals are great
for allowing university researchers to time
to work on-site. "There's a great exchange
of knowledge if we can bring the researcher
to the company site," said Cooksley. ■ Building a
haven for
research labs
The new CICSR/CS building
facilitates new and expanded
collaborative research in many
areas, including the Imager
Lab projects described below.
■ With the new CICSR Building complete,
and new laboratories in place, researchers
are working on many collaborative projects
that some say would not have been possible
without the new facility. With its light, open
spaces, and sophisticated communications
capabilities, the new building lends itself to
creative collaborative research.
One project facilitated by the new building
is Peter Cahoon's work using visual
systems as a tool to aid doctors and dentists
performing facial reconstructive surgery.
The work takes place in the Imager Lab,
which has state-of-the-art imaging equipment that is in use around the clock.
A major coup for the lab is that as part of
this project, which is a collaborative project
with University Computing Services, they
have connected the first active link using
ATM (asynchronous transfer mode)
technology. This exciting new communications medium allows for real-time transfer
of video, images, voice and more data than
ever before. As Imager Lab director Kelly
Booth notes, it has been possible to send
data over phone lines for a long time, but
not at the rate required to move very large
image files across a network, and enable
Peter Cahoon is developing visual tools in the Imager Lab to facilitate facial reconstructive surgery.
viewers at both ends to look at the same
image simultaneously.
The ATM link is between the UBC
Radiology, Craniofacial Biology and the
Imager Lab, and will facilitate work in
developing visual tools for surgical
planning for facial reconstructive surgery.
Cahoon is also working with B.C. Children's Hospital and the RCMP on various
aspects of imaging for facial reconstruction.
Surgeons are interested in being able to
predict how facial surgery will affect young
patients as their bodies grow and mature.
The RCMP are interested in the technology
to develop realistic portraits of missing
children when no current photo has been
available for years. Using available data,
and known growth patterns, a preliminary
study is looking at the feasibility of an
imaging system to show realistic portraits
over years of development.
It's a very complex problem which requires
using data from various sources, including
scans that show bone structure, surface
information, and skin and muscle information, and determining the feasibility of
integrating all three into a single model. It's
a difficult problem, but there are a lot of
people who could make use of the solution.
Rabab Ward of Electrical Engineering is

also at work on imaging problems using the
resources of the Imager Lab. She is working
with Rogers Cable TV to improve the
picture quality and reduce noise in images
sent via the cable network. The research,
funded by NSERC and Rogers Canadian
Cable Labs Fund, has promising applications in the medical field as well.
Some of the projects Ward and her research
team are currently working on deal with:
developing a monitoring system for cable
TV pictures; developing a non-intrusive
system to measure the parameters of cable
TV; developing and building prototypes for
canceling impairments and noise arising in
the cable TV signal; and developing
schemes for reconstructing images blurred
by atmospheric turbulence.
The research into image processing also has
applications in other areas. For example,
one current project involves developing
schemes for restoring mammographic
images so that early signs of cancer are
automatically detected. Another looks at
developing noise-resistant compression
schemes for high-definition television. ■ Video games for math and science instruction
The E-GEMS project focuses on using electronic games to teach math and science to children
■ Learning math and science isn't fun and
games to most young students, but a
multidisciplinary project at UBC has plans
to make it that way. Led by Computer
Science Department head Maria Klawe,
with input from a large and varied group of
researchers, E-GEMS (Electronic Games
for Education in Math and Science) is
aimed at developing computer games that
spark interest in, and/or help children
understand, math and science concepts.
While there is some resistance on the part of
parents and teachers to video games, there
is no denying they have captured the
imagination of today's children. Nintendo is
now a household world. What Klawe
proposes is that rather than ignore this fact,
educators should capitalize on it by
developing games that teach children while
they entertain. She and other E-GEMS
project members believe computer games
should be part of the school curriculum for
intermediate grades. As an example, Klawe
has led the development of Monkey Math, a
collection of prototype games and activities
to help kids learn the concepts of negative
numbers and fractions, topics they tend to
have trouble with. This is a small start
compared with the large vision behind E-
The people involved in the project are a
diverse bunch, including: Computer Science
grad students Kori Inkpen, Rob Scharein,
Kamran Sedighian, Richard Dearden, and
post-doc Joan Lawry; Psychology Ph.D.
student Kelly Davidson; Ann Anderson, a
member of the Education Faculty at UBC;
Rena Upitis, an associate professor of
Education at Queens University; Kelly
Booth head of MAGIC at UBC; and
Computer Science undergraduate students
David Hsu, and Steve Leroux. As well,
employees of Electronic Arts, a multinational computer game developer, are
working on some pieces of the puzzle,
making it a truly interdisciplinary project.
There are many facets to the project, which
is growing all the time. According to project
researcher Rena Upitis, E-GEMS is a true
university-industry partnership between the
researchers and Electronic Arts. "What
they're developing, we research, and what
we research, they develop. It's a two-way
street, a true partnership."
As the world's largest electronic game
developer, Electronic Arts is very interested
in the education market, and in making
games that help kids learn. In Klawe's
vision, there is another aspect as well — the

fact that girls seem to be turned off of math
and science in greater numbers than boys.
As part of the project, she'd like to see
games developed that spark the interest of
girls in math and science.
As part of Kori Inkpen's Ph.D. thesis, she is
studying part of this problem. Inkpen is
studying collaborative play amongst school
children using computers. Her preliminary
results show that pairs of girls perform
better when they share one computer, and
worse when they each have a computer of
their own. This raises questions about
current computer game design — games are
usually one-player scenarios, and if there
are two players, they are usually competing.
Possibly games may appeal more to girls if
there was provision for two people to play
on one computer as a team.
This is one of countless questions that could
be answered during the course of E-GEMS.
Rena Upitis is interested in spatial visualization problems, and is studying how
children learn using a variety of media,
from computers to video to paper models.
Preliminary results show children may have
a preference for the computer, and may
learn better with computers, but more work
needs to be done to reach firm conclusions.
Another long-term goal of E-GEMS is
research that may help keep some children
interested in school who are currently
dropping out. "Through the popular culture
of electronic games, we may be able to help
kids become more interested in math and
science," said Upitis. I feel it's a mistake to
ignore the popular culture. Perhaps if school
and life weren't so separate, more kids
would stay in school."
Other questions the group is studying
include: how to make computer games
more "girl-friendly"; what configuration of
computer system works best for children
and learning; what are the effects of
different environments such as the home;
how is learning affected if a parent or
teacher works with students; how do
educational computer games work with
various learning styles... and more.
According to Upitis, the team is keeping the
focus broad, and its numbers are increasing
all the time. Last summer some 15,000
children took part at a Science World
exhibit as part of the E-GEMS project.
Studies are also taking place in various
schools, to include representation from kids
of varying race, background and socioeconomic status. As Upitis notes, "There's
lots to do," but the group isn't limiting its
scope because of the sheer magnitude of the
task. Instead E-GEMS is structured to grow
and expand as needed to answer the
important questions about how computer
games can help kids, especially girls,
become interested and stay interested in
mathematics and science. ■ Robots that play soccer
The Laboratory for Computational Intelligence has developed
robotic cars that can autonomously play a game of soccer.
Robot soccer researchers (from left)Alan Mackworth, Rod Barman, Stewart Kingdon and Michael
Sahota at work in the Laboratory for Computational Intelligence.
■ It may look like fun and games in the
Laboratory for Computational Intelligence,
with radio-controlled cars whizzing around
a table after a bright pink ball, trying to
shoot it into each other's goal. But in fact,
enabling these robotic cars to engage in a
simple game of soccer is a very complex
research task.
The real challenge of the project, according
to Computer Science graduate student
Michael Sahota is enabling the cars to
respond in real-time to a dynamic situation.
If you scaled the radio-controlled cars used
in the lab up to life-size, their scale speed
would reach 120 kilometres per hour. "The
fact that we're able to control them at this
speed is quite a triumph," said Sahota.
The research project encompasses many
areas of research and development, and was
initiated by professors Alan Mackworth and
Dinesh Pai. Called, Dynamo (Dynamics and
Mobile Robots), the research project is
funded in part by IRIS (Industrial Robotics
& Intelligent Systems) Network of Centres
of Excellence, NSERC and the Canadian
Institute for Advanced Research.
Sahota's contribution is focused on
providing the robots with the necessary
intelligence to play a game of soccer. The
robots are programmed with several playing
modes, including offense, defense and goal.
There are many factors that go into deciding
which mode to play in, including the
positions of the player, the ball and the
opponent. If these were static, the problem
might not be so complex, but when all three
are moving, the robots have to be able to
"think" at the same time as they're acting.
This is an area that needs a lot of work, said
Sahota. Most robots in use today work in
static environments. They think, act, then
stop to think again. This would make for a
rather slow soccer game.
In addition to artificial intelligence research, work had to be done in computer
vision and tracking to make the robotic
soccer game possible. The cars are marked
with large coloured circles, and are tracked
using a video camera mounted above the
testbed, a raised playing field, with a lip
around the edge to contain the game. The
camera is connected to a special-purpose
vision-processing computer which sends
commands back to the car via radio signals.
The cars are standard radio-controlled cars.
At any given time, about eight professors,
students and staff are at work in the lab on
various aspects of the project. For example,
Alan Mackworth, Rod Barman and Stewart
Kingdon designed the colour tracking
system, which has attracted serious
commercial interest (see sidebar). Dinesh
Pai of the Department of Computer Science
has specified constraints for the cars'
motion. These constraints are used to help
the cars plan their path. Given their turning
radius, and the size of the board, it's not
always a simple straight line for the cars to
get to their target.
Sahota notes that the problem of robots
playing soccer has not yet been perfectly
solved. There are times when both cars get
hung up, and sit there looking as if they're
unsure of what to do next. However, the
research team is charging ahead by adding
even more complexity: two cars per team.
Sahota expects it to be a real challenge
getting two cars to co-operate in a dynamic
environment. However, the applications of
the knowledge that will result from this
research could be far-reaching, and far more
serious than a simple game of soccer. ■
New Ties with Industry Liaison
■ CICSR and the UBC Industry Liaison
Office established closer ties recently, as
Doug Gill, Networks Centres of Excellence Technology Transfer Manager, set
up his office in the new CICSR building
temporarily. During his five-month stay,
Gill helped negotiate a licensing agreement for technology developed in one of
CICSR's labs, and helped make a case for
the decentralization of the Industry
Liaison Office.
The Industry Liaison Office works with
UBC researchers to protect their intellectual property through patents, copyright
and trademarks, and negotiates the
licensing of technology to industry. The
Office also negotiates the terms and
conditions to all research contracts
involving UBC staff and industry.
"The Computer Science and CICSR area
is an excellent area in which to consider
establishing closer ties," said Gill. "With
an Industry Liaison staff member on-site,
we can offer better service." While there
are no immediate plans to locate another
Industry Liaison staff member at the
CICSR building, the experiment was
successful enough that such a move may
be considered in the future.
While at the CICSR building, Gill helped
licence the Dynatrack colour tracking
system to an Ontario-based Cognitiative
Systems. The tracking system was
developed in the Laboratory for Computational Intelligence to track the motion of
robotic cars. The technology has applications in any field where tracking with a
video camera system is desired, from
manufacturing to virtual reality. ■ Meeting Place
The MIS Division has developed
software that will help facilitate
the meetings of the future.
■ Many people in today's business world
regard meetings as a necessary evil. It is
necessary for groups of people to meet to
brainstorm, plan and reach consensual
decisions. But many business people regard
meetings as the biggest time-waster in their
day. Research being done at the UBC
Faculty of Commerce may change this.
The Management Information Systems
(MIS) Group, with the help of UBC
Computer Science graduate students, has
developed software called Meeting Place,
which facilitates meetings, helps groups
arrive at decisions, brainstorm, vote, plan,
and more easily carry out all meeting
functions. The goal is to use the software to
study the dynamics of business meetings
and determine how the dynamics change
when computers are used as meeting tools.
However, to date, most of the effort has
been spent developing the software.
Meeting Place is now a fully-functioning
software package, with a seamless user
interface that Commerce associate professor
Bob Goldstein finds superior to commercial
products on the market. The software runs
on the NeXTStep operating system, and
includes modules for messaging,
conferencing, brainstorming, ranking ideas
or candidates, voting, resource allocation,
and idea clarification. The software also
includes modules to preconfigure meetings
ahead of time, and to log meeting events.
Development of Meeting Place began in
1992, and the software is now fully
functional, and ready to run meetings. It has
commercial potential, although that is not
the focus of the developers at the moment.
Goldstein and MIS Division assistant
professor Andrew Trice are exploring the
possibility of adding more features, and
planning their research strategy.
Goldstein has tried out the current commercially-available meeting software and found
the experience "interesting." However, he
found the software he used was not flexible
enough to allow the meeting to flow
naturally. He was always very aware of the
software. Meeting Place will be different,
he said. The goal is to make the software so
flexible, it is an aid that enables meeting
groups to reach their goals more quickly,

Faculty of Commerce, MIS Division.
but it doesn't get in the way of what the
group wants to do.
However, even with the limitations of the
current software on the market, users report
being more satisfied with the decisions
arrived at during computer-assisted
meetings. The software helps build
consensus. That could be because in
computer-aided brainstorming sessions,
ideas are anonymous, so they are judged on
merit alone, and not weighted because of
their source. As well, the computer offers
an impartial, fair way of tabulating the input
of all members at the meeting, and can
calculate a true picture of the overall group
feeling on a subject, (whereas in today's
meetings, "group" decisions are often made
by the most powerful, and most vocal
people present).
Meeting software developers also claim
better productivity and better decisions as a
result of meetings held using their software.
However, these claims have yet to be
scientifically proven. This is a key area of
research that Meeting Place was developed
to facilitate. The software definitely
changes the dynamics of meetings. The
question is does it change them for the
better, and if so, how? Are there situations
that lend themselves to computer-assisted
meetings and others that work better the
old-fashioned way? These are the types of
questions future research at the MIS
Division will answer.
In the meantime, work continues on the
software. The possibilities are endless, but
the types of features Goldstein and Trice are
considering give us a glimpse of what might
constitute a meeting of the future. For one
thing, meeting participants won't all have to
be in the same physical place. Meeting
Place is already set up in a limited way for
distributed meetings, and more functionality
will be possible in the future. Another
possibility is that people won't all have to
attend the meeting at the same time. The
software can make "virtual" meetings
possible, a real benefit to multinational
companies operating in different time zones.
Trice also envisions superior after-meeting
support. The system already logs events
during the meeting. Given this, minutes
could be automatically generated, even
tailored to each meeting participant, with
their own action items flagged. The
Meeting Place team is also looking at more
in-depth logging. They are exploring with
Kelly Booth of the Department of Computer
Science, the possibility of videotaping
meetings, and marking places in the tape
where specific events occurred. So if, for
example, a person not present at the
meeting wanted to see what happened right
before a key decision was made, he could
specify the event recorded by the software,
and have the tape advance to that spot
Possibilities for the software abound, but in
the meantime, the MIS Division is hoping
to construct a meeting room for business to
try out the software's current capabilities.
They have plans for a high-quality boardroom, with computer screens recessed into
the tabletop running Meeting Place
software. The interest from the business
community is high, said Goldstein. They
hope to find corporate sponsors interested
in helping put Meeting Place into action.
Once the meeting room is set up, the
meetings can be monitored and the results
can help advance our knowledge of the
benefits of meeting-facilitation software. ■ PASSING NOTES
