The rapid spread of technological innovations like mobile data services (MDS) has made ubiquitous computing a fact of everyday life for many people. We need therefore to understand the contribution of ubiquitous computing to overall quality of life. This study proposes a theoretical model that connects user satisfaction (a traditional outcome variable of IT) with contributions to quality of life (a new outcome variable for ubiquitous computing) in the domain of MDS. The reliability of the outcome variables and the validity of the proposed model were tested through three empirical studies in Korea. Study results indicate that user satisfaction with MDS affected the contribution of MDS to quality of life in eleven subordinate domains, and these contributions in turn influenced the overall contribution of MDS to quality of life. The paper ends with a discussion of the implications and limitations of the study results.
