1. Visualizing E-Brand Personality: Exploratory Studies on Visual
Attributes and E-Brand Personalities in Korea (pp. 7-34)
Su-e Park, Dongsung Choi, and Jinwoo Kim
The brand personality of an online product and service, usually
represented by a web site, is known as its e-brand personality. In the
competitive conditions of online markets, e-brand personality is agreed to
be an important factor in securing distinctive identity; however, few
studies have suggested how to establish e-brand personality through the
visual design of web sites. This study explores the feasibility of
constructing target e-brand personalities for online services by using
visual attributes. It consists of three consecutive studies. The first
study identified four major dimensions of e-brand personality on diverse
web sites. The second study used 52 experimental home pages to identify
key visual attributes associated with those four personality dimensions.
The third study explored whether those findings from the second study can
be applied in constructing websites for online services. The results show
that two visual attributes, simplicity and cohesion, are closely related
to a bold personality. Three attributes, contrast, density, and
regularity, can be used to create a web site that has an analytical
personality. Contrast, cohesion, density, and regularity are closely
related to a web site that is perceived to have a friendly personality.
Regularity and balance were expected to be related to the sophisticated
personality dimension, but no such relation was identified in the third
study. The article concludes with a discussion of implications,
limitations, and future research directions.
2. The Enhanced Restricted Focus Viewer (pp. 35-54)
Peter Tarasewich, Marc Pomplun, Stephanie Fillion, and Daniel Broberg
The Enhanced Restricted Focus Viewer (ERFV) is a unique software tool for
tracking the visual attention of users in hyperlinked environments such as
Web sites. The software collects data such as mouse clicks along with the
path of the user’s visual attention as they browse a site. Unlike
traditional eye-tracking procedures, the ERFV requires no hardware to
operate other than a personal computer. In addition to cost and time
savings, the ERFV also allows the administration of usability testing to
groups of subjects simultaneously. A laboratory test comparing the ERFV to
a hardware-based eye-tracking system showed that the two methods compare
favorably in terms of how well they track a user’s visual attention. The
usefulness of the ERFV as a usability testing tool was demonstrated
through an experiment that evaluated two Web sites that were equivalent in
content but differed in terms of design. While several open issues
concerning the ERFV still remain, some of these issues are being addressed
through ongoing research efforts.
3. Issues in Building Multi-User Interfaces (pp. 55-74)
V. Srinivasan Rao, Wai-Lan Luk, and John Warren
The proliferation of interest in collaborative computer applications in
the past decade has resulted in a corresponding increase in the interest
in multi-user interfaces. The current research seeks to contribute to an
understanding of the process of developing user models for group
interaction, and to the design and implementation of multi-user interfaces
based on the model. We use group ranking as an exemplar task. User
requirements were identified, by observing groups perform the ranking task
in a non-computer environment. A design was proposed based on the
identified requirements and a prototype implemented. Feedback from
informal user evaluation of the implemented interface is reported.
Insights on the methodology are discussed.
4. Online Consumer Trust and Live Help Interfaces: The Effects of
Text-to-Speech Voice and 3D Avatars (pp. 75-94)
Lingyun Qiu and Izak Benbasat
With the increasing prevalence of online shopping, many companies have
begun to provide Live Help functions, through instant messaging or text
chatting, on their websites to facilitate interactions between online
consumers and customer service representatives (CSRs). The continuing
reliance of these functions on text-based communication limits non-verbal
communication with consumers and the social contexts for the information
conveyed, but with the help of emerging multimedia technologies, companies
can now use computer-generated voice and humanoid avatars to embody CSRs,
thus enriching the interactive experiences of their customers. In this
study, a laboratory experiment was conducted to empirically test the
effects of Text-To-Speech (TTS) voice and 3D avatars on consumer trust
towards CSRs. TTS voice was implemented to deliver answers aloud. A 3D
avatar served as the humanoid representation of a CSR. The results
demonstrate that the presence of TTS voice significantly increases
consumers’ cognitive and emotional trust toward the CSR. These findings
offer practitioners guidelines to improve the interface design of real
time human-to-human communications for e-commerce websites.
5. An Empirical Examination of the Effects of Web Personalization at
Different Stages of Decision-Making (pp. 95-112)
Shuk Ying Ho and Kar Yan Tam
Personalization agents are incorporated in many websites to tailor content
and interfaces for individual users. But in contrast to the proliferation
of personalized web services worldwide, empirical research on the effects
of web personalization is scant. How does exposure to personalized offers
affect subsequent product consideration and choice outcome? Drawing on
literature in human computer interaction (HCI) and user behavior, this
research examines the effect of three major elements of web
personalization strategies on users’ information processing through
different decision-making stages: personalized content quality, feature
overlapping among alternatives, and personalized message framing. These
elements can be manipulated by a firm in implementing its personalization
strategy. A study using a personalized ring-tone download website was
conducted. The findings provide empirical evidence of the effects of web
personalization. In particular, when users are forming their consideration
sets, the agents can play a role in helping users discover new products
and/or generate demand for unfamiliar products. Once a decision has been
made, however, the personalization agent’s persuasive effects diminish.
Our results establish that the role of personalization agents changes at
different stages of users’ decision-making process.
6. Beyond Perceptions and Usage: Impact of Nature of IS Use on IS-enabled
Productivity (pp. 113-136)
Vikas Jain and Shivraj Kanungo
Assessing individual performance impacts from information system (IS) use
has been a key area of concern for IS researchers for many years. However,
past studies have reported mixed results about the relationship between
information system use and performance impacts at the individual level.
The research reported in this paper has two primary objectives: (1) to
propose a model of individual IS-enabled productivity that focuses not
only on the usage of information systems but also the nature of this
usage, and (2) to empirically test the model across two IS applications.
The key premise in this research is that IS use is necessary but not
sufficient to observe productivity gains and that nature of IS use
potentially mediates the relationship between IS use and IS-enabled
productivity. We validate our research model through a survey of 486
individuals across six organizations. Results from this study confirm the
proposition that the nature of IS use is as important as the duration of
use of an information system as a determinant of IS-enabled productivity.
Based on our findings, we provide theoretical and managerial implications
of the relationship between IS-enabled productivity and IS use.
7. Role of Human Computer Interaction (HCI) Factors as Moderators of
Occupational Stress and Work Exhaustion (pp. 137-154)
K.S. Rajeswari and R. N. Anantharaman
Software professionals perform boundary-spanning activities and hence need
strong interpersonal, technical and organizational knowledge to be
professionally competent. They have to perform in a demanding work
environment that is characterized by strict deadlines, differing time
zones, interdependency in teams, increased interaction with clients and
extended work hours. These characteristics lead to occupational stress and
work exhaustion. Yet, the impact of stress is felt in different ways by
different people even if they perform the same functions. These
differences in the perception of stress can be due to varying confidence
in their technical capabilities. Individuals possess varying technical
capabilities based on their acquisition of technical skills, comfort level
in using the technology and intrinsic motivation. These attributes
represent the HCI personality of software professionals. It is therefore
the focus of this paper to examine, if these HCI factors moderate the
relationship between occupational stress and work exhaustion. Data was
collected from software professionals located in Chennai and Bangalore in
India. Data revealed that HCI factors have main effect on work exhaustion,
but does not have moderating effects on work exhaustion. Control over
technology variable emerged as the key variable among the HCI factors that
affects software professionals’ ability to cope with stress and work
exhaustion.
