THE     UNIVERSITY     OF     BRITISH     COLUMBIA
Enhancing E-Commerce Experiences
Commerce professor and ICICS member Izak Benbasat is exploring ways to improve
communication between humans and computers in corporate and e-commerce environments.
► Human-computer Interfaces
► Business-to-consumer E-commerce
► Intelligent Support Systems
In the bustling cyber-world of online
shopping, it is no longer enough to
have a flashy, easy-to-navigate website.
While speed, accuracy and security of
transactions are still crucial design
features for any e-business, how a
company communicates with people
is becoming equally important.
Today's e-shoppers are a savvy,
sceptical and growing market. Izak
Benbasat, Canada Research Chair in
Information Technology Management,
believes that companies should
complement their transactional
activities with relationship-enhancing
ones, such as improved product
description and service, customer
trust and positive company image.
Avatars at Your Service
Any retailer knows that providing
good service is crucial to building relationships with customers. Online shopping is no exception, and e-shoppers
have indicated a need and preference
for some kind of human contact.

Bridging the Software Policy Gap 4   Passing Notes 10 ICICS' growth spurt shows no signs of
slowing down! In this edition of FOCUS,
we introduce you to fifteen recent
members in a special fold-out section. The
four researchers we profile highlight the
innovation and outreach ICICS
members excel at.
Gary Birch's position as head of the
Brain Interface Lab at the G.F. Strong
Rehabilitation Centre keeps him focused
on practical results in his research. Gary
hopes to improve the quality of life for
those living with assistive devices through
his work on self-paced brain interfaces.
The commonalities between problems drives Canada Research Chair Kevin
Murphy's machine learning research.
The probabilistic models he uses to
abstract meaning from massive amounts
of data have application in both robotic
vision and bioinformatics.
Commerce professor Izak Benbasat's
research shows that online consumers are
looking for an e-commerce experience as
informative, responsive, and socially
fulfilling as traditional shopping can
be. The customer-service interface he
is developing to accomplish this will
also have a place in corporate
communications.
E-commerce will benefit from the
middleware that Eric Wohlstadter of
Computer Science has developed to
handle the policy requirements of
different applications within web-based
systems. Eric is also working on a
language that will automate rule-checking
in programming and save developers a lot
of time.
We hope you enjoy this edition of FOCUS.

t: Continued from page 1
Benbasat and colleagues have been
investigating methods to improve
service and product recommendation
systems by incorporating text, speech,
text-to-speech conversion, and
humanoid avatars representing sales
assistants into a Web interface. They
are examining issues such as trust,
social presence (the degree to which
you feel the person with whom you are
communicating is there with you) and
telepresence, or the feeling that you
are in another environment, such as a
store represented on the Web. Their
findings are not surprising. Humans
still prefer a live human voice, which
is the most costly method of providing
customer service and advice. Text-
based systems were the next preferred
method and text-to-speech systems the
least preferred, presumably because
they sounded artificial. The addition of
a "talking head," or three-dimensional
avatar representing a sales assistant,
actually augmented all interactions and
increased the sense of social presence.
Designing Benevolent Agents
The challenge in designing virtual
advice systems is not just to provide
good information, but to understand
affect, or the emotional response of
the shopper. There can also be
incongruence in design goals between
generating higher traffic and sales for
the e-vendor and designing a
recommendation agent (RA) that is
perceived by the customer as being
competent, benevolent and honest—
all dimensions of trustworthiness. "A
lot of people have difficulty ascribing
these human-like characteristics to a
piece of software," admits Benbasat.
He and his colleagues developed an
explanation mechanism that allows RAs
to communicate information in order
to enhance users' trust and beliefs. For
digital camera purchasers, they found
that an RA that provided explanations
about how it reasons and asked
questions that focused on customers'
needs (such as how often the person
wished to take pictures of objects
far away), was perceived as being more
trustworthy than one that asked about
product attributes alone (such as the
power of zoom one wished the camera
to have). However, the improvement
in the level of trust was only ten to
fifteen percent. "There are many ways
to improve these trusting beliefs,"
Benbasat notes. "If you have a
properly designed agent, people will use
other mechanisms in the absence
of explanations." Benbasat's ICICS and
Sauder School of Business colleagues
include Hasan Cavusoglu, Ronald
Cenfetelli and Jai-Yeol Son.
Online Shopping and Virtual
Community Building
An increasing number of e-retail-
ers are tapping into the psychology of
online consumers by designing their
sites as virtual meeting places, where
like-minded consumers can exchange
comments, ideas and product reviews.
The exponential proliferation of blogs,
both private and corporate, reveals
the extent to which people want to
interact online, as well as perform
transactions. Benbasat is studying the
effects of personalization, where a
retailer like Amazon.com might recommend items based on a customer's
prior purchases and online behaviour.
"When you feel that the website is
reacting to the products you are
perusing and trying to understand your
needs, it is a type of personalization
that creates a higher social presence,"
says Benbasat. Similarly, a website that
provides consumer reviews creates a
perceived social presence as well as
useful product information. Together
these aspects significantly affect
customer loyalty. "Shopping is both a
cognitive activity and a social
activity, and when you buy a product
both instrumental reason and affect are
involved. So we are trying to capture all
of these factors in our work."

FOCUS Perfecting Neural Control of   ^^
Assistive Devices
New ICICS member Gary Birch is advancing brain interface technology to improve the
design of assistive devices for people with physical disabilities.
► Brain Interface Technology
► Assistive Devices
► Asynchronous Control
For over thirty years, Gary Birch has been
living without the use of his legs and with
limited use of his arms and hands. A car
accident severed his spinal cord the
summer that he graduated from high
school. Over 1,000 people a year suffer
from spinal cord injuries in Canada. Others
suffering from neuromuscular and other
degenerative diseases have a similar loss of
function and motor control. Gary Birch's
tragic experience motivated him to become
one of the world's top researchers in brain
interface technology and assistive devices.
He started his career at UBC, earning
a BA Sc and then a PhD in Electrical
Engineering in biomedical signal processing
in 1983. Birch is now executive director of
the Neil Squire Society, adjunct professor
in Electrical and Computer Engineering at
UBC, and head of the Brain Interface Lab
at G.F. Strong Rehabilitation Centre.
"What really makes our group unique
is that we work on a day-to-day basis
with people who have all kinds of disabilities," says Birch, who collaborates with
ICICS colleagues Rabab Ward and Peter
Lawrence, both from ECE. "Since our
investigations are rooted in the real world,
we take a practical approach to research
problems." Birch's work in assistive
technologies goes beyond signal processing
to encompass wireless technologies and
human—computer interaction. "I am
interested in any technology that can enable
people with disabilities to better
participate in the home, at
work, or in recreational
activities," he says.
"A lot of work has been done by people who don't have a
background in assistive technology or a connection with the end user, so they
tend to come up with very artificial environments."
4f
Gaining Asynchronous Control
The technology that Birch and his lab
have developed is a brain-controlled switch
that detects brain signals as patterns in a
user's electroencephalograms related to
imagined movements. These signals are
measured by EEG sensors attached
to the scalp. Previous brain interface
(BI) research has focused on synchro
nized control devices, where the system
dictates control. When a synchronized BI
system is turned on, the user is regularly
prompted for input and only allowed to
control the assistive device during specific
periods. Synchronous systems only provide
control intermittently, and not necessarily
when the user intends it.

Fall 2006 Dynamic Matchmaking—
Bridging the Software Policy Gap
Computer scientist Eric Wohlstadter is a middleman of software engineering.
He develops techniques to facilitate component reuse, crosscut between
software languages and systems, and improve design rule checking.
► Adaptive Middleware
► Policy Matchmaking
► Design Rule Optimization
In the dynamic world of software
development, particularly for web-based
services that are distributed over the
Internet, one of the major challenges is the
communication between software components from different systems. For example,
an online retailer and a credit card service
provider each have different policies—or
QoS requirements. The credit card provider's policy might focus on security and privacy, while the online retailer is interested
in functional policies such as shipment
and delivery. The business-to-business web
of a single e-commerce transaction could
involve a company such as Amazon.com
and several different services providers, such
as shippers or credit card companies. In
the space of a few minutes, we can place an
online order, have the transaction
completed and know the delivery date—
all seemingly done with an ease and
simplicity that belies the complexity of
communication between layers of software
components in different systems.
GlueQoS—Middleware "Sweetener"
and Policy Matchmaker
Middleware is software that connects
two otherwise separate applications, such
as two different types of databases, or two
sides of an application, such as clients
and database server. Policy matchmaking
and enforcement over dynamic web-based
systems are key features of the GlueQoS
middleware that ICICS member Eric
Wohlstadter has developed with members
FOCUS
of the Advanced Enterprise Middleware
group at IBM Research. In most current
types of policy middleware, the business
client (such as Amazon) would be asked
to fulfill certain requirements (such as
entering a password) to log on to the server
system, but would have no way of
expressing its needs (fulfillment rate,
shipping, etc.).
The "sweetening" power of GlueQoS
is both dynamic and even-handed.
"The dynamism of our middleware is
the ability to monitor policies to ensure
they are enforced," says Wohlstadter.
"The symmetry allows both client and
server needs to be resolved in policy
matchmaking." His work is currently
being funded by MacDonald Dettwiler
& Associates.
Playing by the Rules
Every programming language has
a set of rules that must be followed in
order for the program to execute. In
addition, individual companies or
software development teams have
their own programming rules which
don't come with "off-the-shelf
programming languages such as
Java or C++.

"Two dominant directions mark the present
engineering world: the diffusion of information
technology into almost every facet of modern

engineering systems. My research originates from
the blending of these two aspects, and targets
advanced microsystems and smart sensors, where
one can take advantage of the combination of
microstructures and advanced signal processing
algorithms. A major theme of "macro-engineering at microscale" is the functional integration
benefits resulting from the tight (nonlinear)
coupling between multiple energy fields
(e.g., mechanical and electrical) at small scales.
These benefits include both the improvement
of the performance of existing devices
(for instance, highly sensitive accelerometers),
and the generation of completely new
applications, such as real-time mechanical
spectrum analyzers. Neuromorphic engineering,
and learning and using some of the mechanisms
devised by nature, together with nonlinear signal
processing, are also placed high on my list of

construction activities to support cost estimates.
Constructability reasoning investigates facility designs. Recognizing constructability issues
early in a project's delivery process helps identify
design constraints which limit a contractor's
ability to plan and perform construction
operations effectively. Specifically, my work
focuses on developing and testing computer-
based models to simulate constructability
reasoning and predict problems. Finally, feature-

Fall 2006 Decoding a Deluge of Data
Computer scientist and statistician Kevin Murphy employs machine learning and probability
theory to develop artificial systems that can make abstract interpretations from low-level data.
► Machine Learning
► Probabilistic Graphical Models
► Computer Vision
"Computers are good at arithmetic and
bad at understanding images, and people
are the other way around," says Kevin
Murphy, new ICICS member and Canada
Research Chair in Machine Learning and
Computational Statistics. He is interested in bridging the gap between current
machine learning abilities and human
abilities of finding and understanding
patterns in data.
One advantage that people have that
machines do not is prior experience.
People learn to solve many related tasks
during their life, so when they are faced
with a new challenge for the first time—
such as recognizing a new kind of vehicle—
they are able to rapidly learn from a small
number of examples. In contrast, in most
current machine learning techniques, the
computer starts out as a "tabula rasa," and
requires a large amount of data to
learn anything.
Object Recognition:
Seeing the Forest before the Trees
One domain in which Murphy has
been exploring such "multi-task learning"
is visual object recognition. The basic idea
is that it may be easier to learn to recognize many things at once than to recognize
objects in isolation. One reason for this is
that visual "parts" can be "shared" across
categories. This reduces the amount of
training data required.
Another reason is that many objects
co-occur, that is, objects together form part
of scenes. It turns out to be easier to
recognize scenes first, and then to
recognize the objects within them. For
example, it is easy to distinguish indoor
images from outdoor images, based on the
global statistics of the image (e.g., average
brightness, presence of horizon lines, etc).
Having recognized the scene as an outdoor one then primes the system to expect
certain kinds of objects, such as cars and
pedestrians. This "top-down" approach to
computer vision is particularly important
in real-time applications like robotics.
Machine Learning for Bioinformatics
Recently, Murphy has started to
collaborate with ICICS colleague
Raymond Ng on a problem in cancer
genetics. Specifically, the goal is to find
repeatable patterns in comparative
genomic hybridization (CGH) data.
"This is essentially a signal
segmentation problem," Murphy says.
"What makes it difficult is that the signal
is so noisy.

Fall 2006 ►   Birch: Continued from page 3
Imagine not being able to move the
cursor of your computer when you want,
or turn on the lights, or change TV
channels. Instead the device operates by
polling the user at regular intervals, which is
disruptive to normal daily activities.
In order to develop asynchronous, or
self-paced, BI devices Birch and his lab
realized the need to define different periods
of control. Intentional control (IC) is
differentiated from the state of No Control
(NC), when a person does not intend use
and wants the system to remain quiet,
such as when they are talking, thinking
or simply observing. Birch realized that
in many applications, people are more
frequently in a NC state. By allowing
the user to define when things happen,
asynchronous control is less intrusive, less
frustrating, less fatiguing, and much more
rewarding for the user.
Currently, there are only three other
groups around the world working on
asynchronous BI technology. Birch and
his lab plan to expand their work in noninvasive EEG systems for use in
implantable devices, where miniature
radio transmitters are screwed into the
skull. Although more invasive, these
devices are desirable from a cosmetic and
practical standpoint, and scientists believe
they will also have an improved signal-
to-noise ratio. "Everything we have learned
about user control challenges can be
applied to implantable technology. So we
are making contributions on two levels."

►   Wohlstadter: Continued from page 4
"People follow these rules for
different reasons," says Wohlstadter.
"Often it is to ensure the software is
easy to maintain." However, this additional
coding can become complicated and
cumbersome over time, especially
when the software is not properly
modularized. Imagine a car being made
as one giant interweaving piece of
machinery, Wohlstadter explains. When
something malfunctioned, you couldn't
just replace a fuel pump or starter; the
entire vehicle would have to be replaced.
Several books have been written on
developing design rules, but so far there
has been a lack of support to encode these
informal rules so they can be automatically
checked or enforced. Wohlstadter
and ICICS colleague Kris De Voider have
been working with Microsoft to develop
a language that is specific for design
rules and that operates on a much higher
level than traditional programming
languages. "The benefit for programmers
is that they can check as many rules as
they want without being limited by
implementation constraints."

►   Murphy: Continued from page 7
In addition, the variation in the signal
due to cancer is masked by other sources
of variation, which are specific to each
person. The challenge is to tease apart
these different signals." The approach
Murphy is following is to use hierarchical
Bayesian models, which are capable
of leveraging prior biological
knowledge.
Computational Statistics
Many of the models that people use
in machine learning—whether for
computer vision, bioinformatics or
other applications—are quite complex.
Computational tractability turns out to
be a very important issue. In a third
strand of research, Murphy is investigating
efficient algorithms for approximate
inference in complex probabilistic
graphical models. He is also interested in
developing software to make such complex
algorithms more widely accessible to the
user community.
