Title: Understanding Cultural Differences in the Use of Mobile Phones
Are there cultural differences in
the ways that people are currently using their mobile phones? What they
expect out of their mobile phone design? What they would like their mobile
phones to be like in the future? Drawing on a series of research studies
conducted in 3 separate countries (Japan, China, and the United States),
this presentation will examine some of the similarities and differences in
mobile phone usage in different cultures.

Title: Human-Computer Interaction for Electronic Commerce:
Impact of Explanations on Trust in Online Recommendation Agents
Slides (2mb)
In electronic commerce, the consumer-company interface is a website that
represents the online storefront of an e-tailer. This web interface is the
company’s window to the world through which communication with customers
takes place and relationships are built. Therefore, electronic commerce
gives rise to new human-computer interaction (HCI) challenges mainly
associated with how to design the web interfaces for effective communication
between customers and online retailers.
This talk will first provide an overview of a research program conducted to
investigate topics associated with HCI design for electronic commerce,
mainly concerned with improving customer-company communications on the web,
including those between customer-products, customer-customers,
customer-salespeople and customer-recommendation agents. The main objectives
these studies will be discussed, and how they can be incorporated into an
overall research framework for conducting HCI studies in the age of
electronic commerce will be described.
The main part of the talk will describe a study that investigates the
effects of different types of explanations on consumers’ initial trust in
online recommendation agents which provide shopping advice based on
user-specified needs and preferences. By extending interpersonal trust to
trust in technological artifacts, consumer trust in recommendation agents is
defined to include three belief components: competence, benevolence, and
integrity. The characteristics of online recommendation agents that may
hamper consumers’ trust building in the agents are identified and
explanation facilities are suggested to facilitate trust building by
directly dealing with these obstacles. This study has suggested three types
of explanations – how explanations, why explanations, and guidance – to be
embedded in the online recommendation agents, and it has examined their
impacts on different trusting beliefs.
The results of a laboratory experiment conducted confirm the important role
of explanation facilities in consumers’ trust building in online
recommendation agents and indicate that different types of explanations
increase different trusting beliefs: the use of how explanations increases
consumer beliefs in the agents’ competence and benevolence, the use of why
explanations increases consumer beliefs in agents’ benevolence, and the use
of guidance increases consumer beliefs in agents’ integrity.

Izak Benbasat, Fellow-Royal Society of Canada, is CANADA Research Chair
in Information Technology Management at the Sauder School of Business,
University of British Columbia (UBC), Vancouver, Canada. He currently serves
as the Chairperson of the Management Information Systems Division. He was
Associate Dean (Faculty Development) from 1996 to 1999, and Associate Dean,
Research, from 2001 to 2002.
Professor Benbasat received his B.A. (1969) in Business Administration from
Robert College, Istanbul, and Master of Science (1971) and Ph.D. (1974) in
Management Information Systems (MIS) from the University of Minnesota.
Professor Benbasat’s current research interests in information technology
(IT) utilization include: 1) evaluating human-computer interfaces for
web-based interface design to facilitate business-to-consumer electronic
commerce; 2) investigating the role of explanations in intelligent support
systems in improving user productivity and knowledge transfer to users; and
3) measuring IT-related competencies, namely, IT knowledge in line managers
and business competence in IT professionals, and their impact on the
effective deployment of IT. The general theme that links his areas of
research interest is improving the communication between IT, management, and
IT users. This communication exits at different levels and has different
facets, e.g., interaction between individual managers and intelligent
decision support systems, customers and web sites, and communication between
IT professionals and line managers.

Title: Three Faces of Human-Computer Interaction -- Human Factors,
Information Systems, and CHI
Three major threads of human-computer interaction research co-exist in the
human factors, information systems, and computer science fields. Information
Science, Design, and other fields are now determining how they should regard
HCI. Ten years ago I contributed to writing one version of what has become
the standard computer science view of HCI history and found it less than
elegant, with arbitrary leaps, unexplained shifts, and unmentioned (and
unsuccessful) efforts to build on common ground that clearly exists across
research threads. Interviews with many principals active in the 1970s and
1980s strengthened my view that history is interpretation. In this talk I
present an interpretation that resolves to my satisfaction the questions I
began with, as well as many that arose in the investigation. A paper has
been accepted for publication in the IEEE Annals of the History of
Computing, and I am keenly looking forward to different interpretations that
will be produced in response to this one.
Bio: Jonathan Grudin earned a BA in mathematics-physics from Reed
College and a Ph.D. in cognitive psychology from UCSD. He has moved several

CHII's third lecture:
Date: Tuesday, October
26th, 3:30pm-5:00pm
Speaker: Dr. Debra Friedman
Audio from lecture
Title: Is More Information
Better for Decision-Making?
An abiding assumption in decision theory is that additional information
allows individuals to make better choices. This is often applied in the
social policy realm. Well-intentioned public and non-profit officials
commonly attempt to provide more information to the public to shape
decisions such as school choice, public transportation usage, and the like.
Recent discussions of the human capacity for assimilating information and
analysis of the costs of gathering information have cast doubt on this
assumption.
Bio: Debra Friedman is
Director of Special Projects, Development and Alumni Relations, and
Affiliate Associate Professor, Evans School of Public Affairs, University of
Washington. She served as Associate Provost for Academic Planning for five
years (1998-2003) and as Associate Dean of Undergraduate Education for three
years prior to that. She teaches a graduate seminar in decision theory in
the Evans School. She holds a PhD in sociology, has won distinguished
teaching awards at the Universities of Washington and Arizona, and is the
author of numerous scholarly articles and a book.

Audio from lecture (introduction low, lecture quality very good)
Title: The structural sources of organizational isomorphism:
Some reflections on power and the flow of information.
Institutional theories of organizational structure routinely overstate
the roles of external constraints and incentives on the organizing processes
and neglect the internal role structure of organizations, which is related
to power and authority. My "reflections" will compare public and private
organizations cross-culturally in order to specify a societal dimension of
organizational isomorphism that is associated with legitimizing authority
within organizations and that influence the use and the diffusion of
information in organizations.
Bio:

CHII's first lecture:
Date: Tuesday, April 20th, 3:30pm-5:00pm
Speakers:
Professor Earl Hunt,
Dr. Susan Joslyn and Karla
Schweitzer from the University of Washington Psychology Department
Title: Which Way
Will the Wind Blow? Person-Machine Co-operation in Aviation Weather
Forecasting.
Slides from the lecture
(3.4mb)
The weather is determined by over a million variables. Not surprisingly,
this poses something of a challenge to a weather forecaster. Modern weather
forecasters have available historical records, satellite observations,
knowledge of local topography, recordings from various stations and data
collection points (e.g. bouys, radiosondes), and, far from least important,
the predictions offered by mathematical models. How do they make sense of
all this information? We will report our observations of how Naval Aviation
weather forecasters do their jobs, and more particularly, how they use the
mathematical models available to them. To what extent do weather forecasters
go beyond the predictions of a mathematical model? To what extent should
they? We report data addressing these questions.
Bio:
Earl Hunt is Professor Emeritus, University of Washington. He holds a
Ph.D. from Yale University, 1960.
Previous appointments include Yale, UCLA, U. of Sydney (Australia). Prof.
Hunt has
held appointments in Psychology and adjunct appointment in Computer Science
since 1966. He has had visiting appointments at the U. of Texas
(Austin) and U. of Calif. (Santa Barbara)
Prof. Hunt has been interested in higher order cognition by both man and
machine, since his Ph.D. dissertation, which was a computer simulation of
human logical pattern recognition. (To give you an idea of how long ago that
was, the program was written in an assembly language and Prof.
Hunt had to travel back and forth from New Haven to Boston, because the Yale
computer was not large enough to run the program.)
He has written 5 books and over 200 professional articles on topics related
to cognition. He is perhaps best known, in addition to various simulation
studies, for his attention to individual differences in various aspects of
cognition, ranging from verbal skills to the deployment of attention. His
1995 book on the cognitive skills of the coming workforce, WILL WE BE SMART
ENOUGH?, won the American Psychological Association's William James prize in
1996. Much of his recent work has been focused on individual differences in
knowledge organization, with an emphasis on how knowledge of these
differences can improve education. He and his colleagues created the
DIAGNOSER WWW based program, which delivers individualized instruction in
introductory physics to students literally around the world. Another of his
current projects, which he will talk about today, is the interplay between
mathematical models and human decision making to attack the complex problem
of weather forecasting
