Dear AIS Community:
In the aftermath of an eventful holiday weekend and an unexpected
snowfall in the Northeast USA, we are happy to announce the first
issue of the 10th volume of AIS Transactions on Human-Computer
Interaction (THCI). This issue, we have two research articles,
which were posted on time, just before the holiday started.
THCI is one of the journals in the AIS (Association for
Information Systems) e-library at
http://aisel.aisnet.org/thci. To
increase awareness and readership, THCI is still freely available
to everyone during its initial years of publishing. You can find
information related to all aspects of THCI at its website
(
http://aisel.aisnet.org/), including how to submit. We would like
to thank AIS
<http://home.aisnet.org/> Council for its
continued support of the journal. And, as always, we are happy to
announce that we have published the journal on time for all 37
issues.

Antecedents and Consequents of Information Usefulness in
User-generated Online Reviews: A Multi-group Moderation Analysis
of Review Valence

Abstract:
Online reviews have become a critical component of consumers'
Web-based search queries and help them minimize uncertainty and
risk associated with purchase decisions. Not only do customers
perceive online reviews to be more "real", but also online reviews
enable opportunities for interactivity between consumers, which
makes them a popular source of information when consumers make
(online) purchase decisions. In this study, we examine the impact
of online reviews on consumers' beliefs, brand attitudes, and
purchase intention by theoretically extending the information
adoption model (IAM) with constructs from consumer research. To do
so, we used data from a scenariobased online experiment and
manipulated three review characteristics (currency, accuracy, and
credibility) using carefully selected TripAdvisor reviews. Using a
partial-least squares approach (PLS) to structural equation model
(SEM), we found strong empirical support for our hypotheses that
review quality and reviewer credib
ility drive information usefulness and that information
usefulness, in turn, drives consumers' attitudes toward and their
intention to purchase from a brand. Using PLS multi-group
analysis, we further explored the moderating role of review
valence-positive versus negative-and found significant differences
in the importance of the drivers of information usefulness and its
consequents. We discuss our study's implications for theory and
practice.
Real-time Prediction of User Performance based on Pupillary
Assessment via Eye Tracking

and Management, Germany

Abstract:
We propose a method to predict user performance based on
eye-tracking. The method uses eye-tracking-based pupillometry to
capture pupil diameter data and calculates-based on a Random
Forest algorithm-user performance expectations. We conducted a
large-scale experimental evaluation (125 participants aged from 21
to 61 years) and found promising results that pave the way for a
dynamic real-time adaption of IT to a user's mental effort and
expected user performance. We have already achieved a good
classification accuracy of user performance after only 40 seconds
(5% of the mean total trial time that our participants took to
complete our experiment). The non-invasive contact-free method can
be applied cost-efficiently both in research and practical
environments.

Call for Papers
==================
THCI is a high-quality peer-reviewed international scholarly
journal on Human-Computer Interaction. As an AIS journal, THCI is
oriented to the Information Systems community, emphasizing
applications in business, managerial, organizational, and cultural
contexts. However, it is open to all related communities that
share intellectual interests in HCI phenomena and issues. The
editorial objective is to enhance and communicate knowledge about
the interplay among humans, information, technologies, and tasks
in order to guide the development and use of human-centered
Information and Communication Technologies (ICT) and services for
individuals, groups, organizations, and communities.
Topics of interest to THCI include but are not limited to the
following:
* The behavioral, cognitive, motivational and affective aspects of
human and technology interaction
* User task analysis and modeling; fit between representations and
task types
* Digital documents/genres; human information seeking and web
navigation behaviors; human information interaction; information
visualization
* Social media; social computing; virtual communities
* Behavioral information security and information assurance;
privacy and trust in human technology interaction
* User interface design and evaluation for various applications in
business, managerial, organizational, educational, social,
cultural, non-work, and other domains
* Integrated and/or innovative approaches, guidelines, and
standards or metrics for human centered analysis, design,
construction, evaluation, and use of interactive devices and
information systems
* Information systems usability engineering; universal usability
* The impact of interfaces/information technology on people's
attitude, behavior, performance, perception, and productivity
* Implications and consequences of technological change on
individuals, groups, society, and socio-technical units
* Software learning and training issues such as perceptual,
cognitive, and motivational aspects of learning
* Gender and information technology
* The elderly, the young, and special needs populations for new
applications, modalities, and multimedia interaction
* Issues in HCI education
The language for the journal is English. The audience includes
international scholars and practitioners who conduct research on
issues related to the objectives of the journal. The publication
frequency is quarterly: 4 issues per year to be published in
March, June, September, and December. The AIS Special Interest
Group on Human-Computer Interaction (SIGHCI,
http://sigs.aisnet.org/SIGHCI/) is the official sponsor of THCI.
