*** Apologies if you receive this call more than once ***

** Final Call for Participation **
A full day workshop at NordiCHI 2012, October 14, 2012, Copenhagen, Denmark

- Extended position paper submission deadline: August 20, 2012
- Feedback to authors: August 31, 2012
- Camera ready paper version: September 14, 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 systems. 
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. 
(1) Wang, Y. and Emurian, H. An overview of online trust: Concepts, 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 [log in to unmask] At least one author of accepted papers needs to register for the workshop and for one day of the conference itself.
