Abstract

Ubiquitous systems are, in principle, autonomous and capable of perceiving the environment, and user activities and needs. However, this perception and decision autonomously demands user confidence in the system operation what makes difficult the acceptance and use of this type of system.To ensure That trust is a difficult and even more challenging task in ubiquitous systems due to their peculiarities (e.g., context-awareness). One of the possible techniques for the assessment of this feature is to apply measurements. This article presents then a set of thirteen quality measures to evaluate the confidence in the functioning (i.e., the dependability characteristic) in ubiquitous systems. To evaluate this set of measurements, three case studies are used and also described in this paper.
