NordiCHI’12 WS: User-centered Trust in Interactive Systems

A full day workshop at NordiCHI 2012, October 14, 2012, Copenhagen, Denmark

– Position paper submission deadline: August 13, 2012
– Feedback to authors: August 27, 2012
– Camera ready paper version: September 10, 2012
– Workshop at NordiCHI 2012: October 14, 2012

Trust is increasingly important in several information communication
technology (ICT) related areas. Nevertheless, there is still no unified
definition of trust in technologies.
This full day workshop brings researchers, experts, and practitioners
together to discuss and create a more unified understanding and definition
of trust, as well as related research areas and methods, as a basis for a
working community. The main outcome of the workshop is the creation of a
working definition of trust and the exchange and introduction to research
and methods related to user-centered trust in interactive systems.

Human trust in technologies is increasingly important, as the number of
applications using confidential data of the user steadily rising. Websites
require users to enter credit card information; intelligent homes that
support the residents based on their behavior; and location-based services
on mobile devices are frequently used in our daily lives. As technologies
pervade our lives and they become more complex, it is crucial to inform
users about security and privacy issues and create justified trust in ICT
Yet, there is no common understanding of how a user’s trust in a certain
technology can be defined and what factors evoke and support trust.
According to Wang and Emurian (1) two main reasons for multiple
definitions of trust can be identified:
1. Trust is an abstract concept and is often used interchangeably with
related concepts such as credibility, reliability, or confidence.
2. Trust is a multi-faceted, subjective concept that incorporates
cognitive, emotional, and behavioral dimensions. To investigate trust in
interactive technologies and to design trustworthy applications, we need
to share a common understanding of trust.

So far the trust issue has been discussed in the HCI community very
broadly within workshops at CHI, CSCW, or Soups with respect to usable
privacy, security, risk and online trust, thereby considering different
objects of trust (e.g. websites, companies, individuals). Furthermore,
trust has been discussed generally as a factor within user experience
workshops (e.g. at NordiCHI 06). In this workshop the focus will be
narrowed explicitly on 1. the human-centered perspective on trust, 2.
factors contributing to trust, including properties of the trustor and the
trustee, and their relation, thereby focusing on 3. systems as trustees.
Therefore, the main goal of this workshop is to bring together
researchers, experts, and practitioners from different disciplines to
discuss the definitions of trust as well as current research and methods
to measure trust from a human-centered perspective. We want to identify
factors contributing to trust and trustworthiness of interactive systems.
The workshop shall provide input to a common definition of trust, as well
as an overview of the current state-of-the-art in trust research in a
white paper to be published with the results of the workshop.
Additionally, the workshop should serve as a starting point for further
cooperation and networking to improve the created definition over time.

elements, and implications, 2005

The workshop aims to bring together a diverse community of researchers and
practitioners working on trust. It addresses the following topics:
– Definitions of trust in interactive systems: which definitions do exist
and are incorporated in research?
– Contributing factors to trust, such as e.g. reliability, benevolence,
vulnerability: which factors have to be considered about the trustor and
the trustee?
– Methods to measure trust, such as e.g. questionnaires, physiological
measures, behavioral observation

Submissions are expected in the form of a position paper (no longer than 4
pages) discussing ideas, facts, situations, methods, procedures or results
focused on the workshop topic areas. The submission must be formatted
according to the ACM SICGCHI extended abstracts format:
Submissions should be sent by email to At least one
author of accepted papers needs to register for the workshop and for one
day of the conference itself.)
