Ubiquitous computing systems can cause serious problems for user trust. In particular if the system is self-adaptive and situations appear which are poorly self-explanatory. In this paper we aim at the trust management of adaptive systems. We present a user study that covers the correlation of trust dimensions and user feelings on user trust. As results of this study, a Bayesian Network is introduced that, at the design time and runtime of the system, provides knowledge about the interplay between a truster’s disposition, system events and actions, trust dimensions, user trust and user response.
