    Technology acceptance research has shown that trust is an important factor fostering use of information systems (IS). As a result, numerous IS researchers have studied factors that build trust in IS. However, IS research on trust has mainly focused on user's trust in the IS itself, neglecting other targets of trust that might also drive IS use from a user's point of view. Accordingly, we investigate the importance of different targets of trust in IS use. Therefore, we use the concept of a network of trust and identify four different targets of trust that are prevalent. Afterwards, we develop our research model and evaluate it using a free simulation experiment. The results show that multiple targets of trust are important in the context of IS use. In particular, we highlight the importance of a second target - trust in the provider - which is equally important as trust in the IS itself. Consequently, IS providers should focus not only on fostering users' trust in their IS but also on positioning themselves as trustworthy providers. Additionally, we show that a third target - trust in the Internet - has significant indirect effects on important constructs in the context of IS use.

    Trust has been shown as a crucial factor for the adoption of new technologies. Surprisingly, trust literature offers very little guidance for systematically integrating the vast amount of behavioral trust results into the development of computing systems. The aim of this article is to develop a method for deriving trust supporting components for ubiquitous computing systems. The method is used to derive four trust supporting components for a ubiquitous restaurant recommendation system. Afterwards, the system is evaluated using a laboratory experiment with 166 undergraduate students. The results show that the users’ trust as well as their intention to use the system could be significantly increased. To the best of our knowledge, this is the first article developing and evaluating a method for systematically integrating the behavioral trust results into the development of a computing system and its value.

    A major challenge for ubiquitous system design is creating applications that are legal-compatible and accepted by their intended users. Today's European data protection principles contradict the ideas of ubiquitous computing. Additionally, users have to deal with unconventional interaction concepts leading to a low amount of trust and acceptance in such systems. Current development approaches do not sufficiently cover these concerns, as they do not systematically incorporate expertise from the relevant disciplines. We present a novel development approach for ubiquitous systems that explicitly addresses these concerns. Our primary task was to manage the increased number of stakeholders and dependencies, respectively conflicts between requirements of the particular disciplines. The approach incorporates predefined artifacts and a defined workflow with responsibilities, as well as suggesting how to develop mutual understanding. We apply this multidisciplinary approach to develop the ubiquitous application Meet-U.

    How to Use Behavioral Research Insights on Trust for HCI System Design

    Trust has been shown to be a major antecedent of technology acceptance and usage. Consequently, behavioral research has created vast insights on trust building. However, only a small fraction of the existing literature also shows ways of systematically including these insights into system design. Hence, the potential of most behavioral insights on trust for developing new systems often remains only partly realized. To alleviate this problem, we present a way to systematically derive trust-supporting design elements using trust theory. Using a laboratory experiment, we show that the trust-related design elements derived from theory are regarded as being important by the participants, and significantly increased their trust in a restaurant recommendation system as well as in their intention to use it in the future.

    IT artifacts often take the role of a trustee in a trust relationship between users and IT artifacts. The goal of this paper is to increase the understanding of the formation of trust in such trust relationships. Instead of using the predominant theoretical foundation of interpersonal trust, we use the theoretical foundation of trust in automation from the HCI discipline for studying the formation of trust. Since we aim at creating insights on the formation of trust and its dimensions, we develop a formative first-order, formative second-order measurement model for trust. To evaluate the impact of the single indicators and dimensions on trust, we conduct a laboratory experiment. Our results show that the dimensions performance, process and purpose have a comparable impact on trust, and that indicators related to user data are especially important. The results complement existing insights, deepening the understanding of the formation of trust in IT artifacts.

    Towards a Theory of Explanation and Prediction for the Formation of Trust in IT Artifacts

    In this paper we argue that the predominant trust conceptualization in IS has a major weakness when researching trust in IT artifacts and that a theory of explanation and prediction for the formation of trust in IT artifacts is necessary to face the upcoming challenges. Thus, we motivate a trust conceptualization from the HCI discipline, and develop a formative measurement model for trust in IT artifacts to achieve deeper insights on the formation of trust. The results of our pre-study with 102 undergraduate students suggest that the new conceptualization is valueable for creating the desired insights on the formation of trust in IT artifacts. In an upcoming field experiment with about 250 users we expect to gain more detailed and reliable insights in the formation of trust in IT artifacts allowing us to derive a first theory of explanation and prediction for the formation of trust in IT artifacts.

    IS research has shown the importance of trust in domains such as e-commerce or technology acceptance. Researchers also emphasize the importance of the identification of factors that influence trust. Unfortunately, the currently dominant reflective measurement does not offer these insights, and thus this contribution aims at developing a formative measurement model for trust. To achieve this, we address three research questions: a) How can trust be measured, considering trust and measurement theory? b) What indicators should be included in a formative measurement model for trust? c) What is the value of a formative measurement of trust compared to a reflective one? Our results show that the formative measurement model offers detailed insights on the impact of single factors influencing trust. We show that in our study, ability affects trust over twice as much other factors such as benevolence or trustor's propensity.

    The application of ubiquitous and social computational systems shows a rapidly increasing trend in our everyday environments: Enhancing social interactions and communication in both online and real-world settings is an important issue in a broad range of application contexts. This chapter describes the development of ubiquitous and social software for enhancing social networking. The Connect-U demonstrator features a class of such applications. In particular, it comprises the Conferator and MyGroup applications for enabling smarter social interactions in the context of conferences and working groups. We describe the applied socio-technical design process, and discuss experiences and lessons learned.
