- Gender and Personality in
Media Rich Interfaces: Do Birds of a Feather Flock Together?
Traci J. Hess, Mark A. Fuller and John Mathew
This research explores how user and interface characteristics can interact
to influence decision performance. Specifically, this research examines the
effects of gender, personality similarity, and increased levels of
information cues on user involvement with a computer-based decision aid. In
addition, this research explores the downstream effects of user involvement
on decision time, effort, satisfaction, confidence, and quality. Findings
indicate that gender has a significant influence on user involvement, and
that involvement and the level of information cues provided by the decision
aid have a direct influence on decision performance.
- A Test of the Theory of
DSS Design for User Calibration: The Effects of Expressiveness and
Visibility on User Calibration.
Brian M. Ashford and George M. Kasper
This paper reports a test of the theory of decision support systems design
for user calibration that compares the efficiency of the visual computing
paradigm with that of the conventional text paradigm over varied levels of
problem novelty. Perfect user calibration exists when a user’s confidence in
a decision equals the quality of the decision. The laboratory study reported
here compared the effects on user calibration of problems depicted either
using a text paradigm or visual computing paradigm. The results support the
theory. When problems are new and novel, visual depiction improves user
calibration. As problems became more familiar and problem novelty decreases,
no difference was found in user calibration between subjects exposed to
visibility diagrams and those exposed to a traditional text paradigm.
- When Information
Technology Design Favors Form over Function: Where is the Value-added
"Tipping Point"?
Rita M. Vick and Brent Auernheimer
Performing usability analysis early in the design process results in lower
overall development, deployment, and maintenance costs. Pre-development user
and task analysis through questionnaires, observation, low-fidelity
prototyping, and usability testing enables productive interactive testing of
subsequent operable system prototypes. This helps assure a positive return
on investment in information technology. When usercentered design assessment
is supplanted by assumptions about user, task, and work environment, the
result is often production of applications embellished with functionality
unrelated to the user’s task. Surveys were administered to elicit user
perception of system usability and usefulness and of satisfaction with
intra-team interaction. This was the first step in determining the
relationship between form and function for users of a Synchronous
Distributed-Decision Support System (SD-DSS). It was anticipated that the
teamwork process would be most troublesome while the SD-DSS would be
perceived as easy to use and functional. The reverse proved to be the case.
- A Communication Goals
Model of Online Persuasion.
E. Vance Wilson and Ying Lu
Online communication media are being used increasingly for attempts to
persuade message receivers. This paper presents a theoretical model that
predicts outcomes of online persuasion based on the structure of primary and
secondary goals message receivers hold toward the communication.
- The "Voice Effect" in
Groups.
Tom L. Roberts and Paul Benjamin Lowry
This study looks at how collaborative technology, proximity choices, and
group size can affect voicing in groups. Results of the study, involving two
experiments with 550 participants, show that collaborative technology can
improve an individual’s desire to voice, instrumental motives to voice,
non-instrumental motives to voice, and the opportunity to voice in
face-to-face groups. The results also show that the use of collaborative
technology can lesson individual voice losses as groups increase in size
especially in distributed environments. These findings have important
implications in group interactions using technology.
- An Empirical Investigation
of Antecedents of Internet Abuse in the Workplace.
Dennis F. Galletta and Peter Polak
This study examined the extent to which employees engage in Internet abuse,
and whether any of 15 antecedents predict the amount of that abuse. Data
were collected from 571 Usenet users in an on-line survey. Aggregating the
time for each of the eleven listed methods of Internet abuse revealed a
total of 5.8 hours per week, on average. Most of the antecedents in two of
the three Theory of Planned Behavior (TPB) categories (Attitudes and
Subjective Norms), were significant, and none of the antecedents in the
third TPB category (Perceived Behavioral Control) showed significance.
addiction, self-justification, job satisfaction, peer culture, and
supervisor culture were significant predictors of Internet abuse.
Exploratory demographic factors computer experience, gender, and firm
revenue also showed predictive power.
- HCI Research Transfer to
Practice: Better Together (Panel)
Mary Czerwinski, Izak Benbasat, Julie Ratner, Radhika Santhanam, Peter Todd
Currently, HCI researchers and HCI practitioners work in relatively separate
spheres of influence. Practitioners often question the value of academic HCI
research and desire more practical directions. HCI researchers often wonder
if their research findings are communicated via the optimal channels for
influencing practitioners’ process and direction, or whether their results
generalize to the real workaday world of HCI. This panel attempts to outline
what practitioners need from their academic partners, and how they think
these needs can be addressed by academic research. Academics on the panel
will state what they see as interesting future research challenges, and
whether or how they think they can address the practitioner community’s
interests. The practitioners on the panel will then state their opinions
about the opportunities for technology transfer from academia to practice.
- A Model Made of Paper:
Clinicians Navigate the Electronic Health Record
Catherine Arnott Smith
The electronic health record (EHR) is actually an aggregation of individual
clinical documents. Medical records document not only the knowledge domains
of clinical practice, but the work processes and practices that support
these domains. Human-computer interaction is an important factor in EHR
system success: researchers have argued that clinician readers consciously
perceive the context of production, and integrate an understanding of the
producer into their understanding of the data. In support, this paper
reports findings of an information retrieval study using a simulated EHR
containing
deidentified clinical documents. Physician subjects verbally demonstrated
use of a mental model of the paper medical record during their navigation of
the system. Clinicians may actively apply a mental representation of their
domain of practice—and actively refer to this paperbased knowledge base—when
they access medical data. An understanding of the mental models that
clinicians use would greatly inform our understanding of EHR systems.
- Effect of Presentation
Flaws on Users' Perception of Quality of On-Line Stores' Web Sites: Is it
Perception that really Counts?
Andrea Everard and Dennis F. Galletta *
Presentation flaws are abundant in web sites, but there has been no study to
determine how presentation flaws affect consumers’ perceptions of quality of
an on-line store, trust in the store, and ultimately the intention to
purchase. The theoretical foundation stems from various relevant streams of
literature: trust and credibility, impression formation, and impression
management. A laboratory
experiment examined three main factors, incompleteness, error, and poor
style, and used 160 student subjects in a completely balanced, fully
factorial design (2x2x2). It was found that error, incompleteness, and poor
style affected consumers’ perceived quality of the web site. Furthermore, it
was found that the relationship between the factors and perceived quality
was mediated by the
perception of the flaws. The perception of flaws rather than the actual
flaws influenced users’ perception of quality.
- Exploring Website
Evaluation Criteria using the Repertory Grid Technique: A Web Designers'
Perspective.
Felix B Tan and Lai Lai Tung
This study aims to investigate web designers’ perceptions of an “effective”
website. Twenty web designers were interviewed using Kelly’s Repertory Grid
Technique in order to elicit factors that they consider important when
designing or developing B2C websites. Using grounded theory approach, these
elicited data were then classified into 14 meta-categories. The intensive
nature of the interviews eventually gave rise to a comprehensive framework
that broadens the base of existing web evaluation literature. This framework
is based on an adapted Technology Acceptance Model with the 4 dimensions of
Perceived Ease of Use, Perceived Usefulness, Perceived Playfulness and
Attractiveness.
- Usability and Efficacy
Reactions to Object-Orientation: The Impact of Prior Knowledge.
Liping Liu
In this paper, we examine how prior knowledge impacts usability and efficacy
reactions to object-oriented techniques. We develop research hypotheses
based on the multiconstraint theory of analogical reasoning. We empirically
test the hypotheses in an open learning setting. We observed a significant
interaction effect: the subjects with prior knowledge on either data or
process modeling
technique perceived greater difficulty and less confidence in learning
object-oriented techniques than novices as well as those who have prior
knowledge on both structured techniques. Prior knowledge explained 19% of
the variance in both usability and efficacy reactions and, as a common
cause, partially explained their correlation.
- Evaluation of the Impacts
of Data Model and Query Language on Query Performance.
Hock Chuan Chan and Lian Xiang
It is important to understand how users can utilize database systems more
effectively to enhance performance. A major research interest is to evaluate
and compare user performance across different data models and query
languages. So far, experiments have tested combinations of model plus
language. An interesting theoretical and practical question is: how much of
the performance difference is caused by the data model itself, and how much
by the additional query language syntax? A cognitive model of query
processing suggests measurement at two stages. The data model has impact at
the first stage, and the model with the query language syntax together has
the impact at the second stage. An experiment that compares the
objected-oriented and relational models and query languages at the two
stages provides fresh results.
- End User Query
Performance: The Interaction of User Characteristics and Information Request
Ambiguity.
Paul L. Bowen, Fiona H. Rohde and Chiu Yueh Alice Wu
This paper investigates the effects of personality characteristics on
individuals’ abilities to resolve ambiguity in an information retrieval
environment. In particular, this research examines the effects on query
performance of the interaction of personality characteristics (as measured
using the NEO PI-R) with information requests that contained extraneous,
syntactic, or both extraneous and syntactic ambiguities. The results
indicate that ambiguity affected performance. The results also show that
various personality dimensions significantly affect end-users’ abilities to
compose accurate queries. Neuroticism, agreeableness, openness to
experience, and conscientiousness affected the number of errors made in the
query formulations. Conscientiousness affected the length of time taken to
compose the queries and neuroticism affected the confidence end users had in
the accuracy of their queries. In addition, the results indicated that,
while the personality dimensions affected performance, there was no
interaction between the personality dimensions and ambiguity.
- Development of a Framework
for Trust in Mobile Commerce.
Keng Siau, Hong Sheng and Fiona Nah *
Mobile commerce represents a significant development in e-commerce. Despite
the potential of mobile commerce, trust is a major obstacle in its adoption
and development. The focus of this research is to develop a framework to
identify the factors influencing trust in mobile commerce and to explain the
development of such trust using a means-ends objective network. We utilized
the Value- Focused Thinking approach to interview subjects in order to
identify their fundamental and means objectives concerning trust in mobile
commerce and to construct a means-ends objective network. A trust framework
is developed from the means-ends objective network. As one of the first
research on trust in mobile commerce, the framework developed in this study
provides valuable information for researchers and practitioners, and serves
as a conceptual foundation for future research in mobile commerce.
- A Study of Task
Characteristics and User Intention to Use Handheld Devices for Mobile
Commerce.
Xiaowen Fang, Susy Chan, Jacek Brzezinski and Shuang Xu *
Interface design and the selection of appropriate tasks for small-screen
mobile applications are issues critical for mobile commerce. Our earlier
research has identified five major task factors that may influence user
intention to use handheld devices for wireless applications. These factors
are: perceived ease of use, perceived usefulness, perceived playfulness,
perceived task complexity, and perceived security. We followed up with a
questionnairebased empirical study to validate the relative impact of these
proposed task factors on user intention to use handheld devices for mobile
commerce. This paper confirms significant correlations between the task
factors and user intention. However, only three of the five factors --
perceived usefulness, perceived security, and perceived playfulness -- are
important to user intention, explaining 30% of the variations in a multiple
regression model. This study makes a unique contribution to HCI and MIS
research by providing empirical evidence of user perception of task
characteristics for mobile commerce.
- Post-Adoption Behavior of
Mobile Internet Users: A Model-Based Comparison between Continuers and
Discontinuers.
Hoyoung Kim and Jinwoo Kim *
Many mobile Internet users are not continuing to use mobile Internet
services after initial use. This study aims to explore how such users
(discontinuers) differ from ongoing users (continuers) in terms of accepting
mobile Internet technology. We propose an adoption model for the mobile
Internet consisting of seven critical factors. An on-line survey was
conducted on the basis of this model to compare
continuers and discontinuers. The survey results show that discontinuers are
more sensitive to usefulness and social influences in using mobile Internet
services, while continuers are more sensitive to ubiquitous connectivity.
- Finding Common Ground
Among HCI Reference Disciplines (Panel)
Dennis Galletta, Jonathan Lazar, Judy Olson, Dov Te'eni, Marilyn Tremaine,
and Jane Webster
Five panelists provide an interesting set of contrasting points of view of
the HCI field from four distinct disciplines: Business, Computer Science,
Information Science, and Psychology. Panelists are asked to respond to six
questions in their presentations that address what their particular field
offers that is unique, what seems to be quite similar, the effects of the
overlaps, and advice for the future. Many of the panelists represent
multiple fields, providing a unique opportunity to address the issues of
overlap.
- Is Relevance Relevant?
Investigating Coherence in Knowledge Sharing Environments.
Andrew Gemino, Drew Parker and Adrienne Olnick Kutzschan
This paper focuses on the impact of relevant backgrounds on
computer-mediated knowledge sharing and individual knowledge acquisition. An
experiment is described based on the coherence principle from the Cognitive
Theory of Multi-Media Learning. Results suggest groups using visual chat
scored higher in retention and understanding than individuals working alone.
In addition, participants using visual chat with relevant backgrounds
obtained higher levels of understanding than participants using no relevance
or irrelevant backgrounds. These results support the coherence principle in
the cognitive theory of multimedia learning and suggest new directions in
the design and evaluation of knowledge sharing environments.
- Interactivity and Control:
the Case of Dynamic Maps for Navigation in Hypertext.
Dov Te'eni and Hadar Ronen
Rich information environments such as online tutorials and web-books pose
considerable difficulties for users, of which the most notable is being
‘lost in hypertext’. If these environments are to become commonplace, they
must be designed to relieve users of these difficulties. In this paper we
study the effects of dynamic navigational maps on orientation and search
performance. We designed a conceptual map that tracks the user’s position
vis-à-vis the content of the web-book and the history of the user’s visits.
We show how these maps improve search performance significantly in terms of
efficiency (number of clicks) but only weakly in terms of time or accuracy.
We call for more research on how to enhance user control in complex
information environments.
