Ubiquitous computing services constitute a new information technology that can be used in
thousands of potential applications and environments. Ubiquitous computing is also changing
the classic paradigm of information technology as it is forcing social and cultural changes.
Determining factors affecting the use of ubiquitous services is essential to correctly define the
characteristics of new value added services. However, this study investigates not only these
factors, but also the moderating effect of previous experience. Due to the technological nature
of ubiquitous services, previous experience alters the way in which potential users face these
services. Findings suggest that previous experience changes the way in which antecedent
relates to basic TAM constructs. The derived research models and empirical results also
provide valuable indicators for future research and managerial guidelines for the successful
adoption of ubiquitous computing servicesJunta de Andalucia. Consejería de Economía, Innovación, Ciencia y Empleo P12-SEJ-32
