Trust-based Decision-Making for Energy-Aware Device Management


Trust-based Decision-Making for Energy-Aware Device Management


in: Aalborg, Denmark Proceedings of the 22nd Conference on User Modeling, Adaptation and Personalization (UMAP 2014)


Smart energy systems are able to support users in saving energy by controlling devices, such as lights or displays, depending on context information, such as the brightness in a room or the presence of users. However, proactive decisions should also match the users' preferences to maintain users' trust in the system. Wrong decisions could negatively influence users' acceptance of a system and at worst could make them abandon the system. In this paper, a trust-based model, called User Trust Model (UTM), for automatic decision-making is proposed, which is based on Bayesian Networks. The UTM's construction, the initialization with empirical data gathered in an online survey, and its integration in an office setting are described. Furthermore, the results of a user study investigating users' experience and acceptance are presented.
