The aim of this study is to develop a scale measuring satisfaction to ubiquitous services. Since the ubiquitous service is not vet implemented but under development, conventional scale construction methods are not directly applicable. In this study, the characteristics of items are studied by observing individual's responses after presenting a video clip describing virtual services. The constructs of ubiquitous service are defined based on those of information system and previous studies of ubiquitous services. Items were generated to reflect the constructs. In the first study, we found six factors (me-centeredness, attractiveness, usability, trust, accessibility, ownership) in the ubiquitous service scale by using exploratory and confirmatory factor analysis. Some items were dropped out that did not show good psychometric properties. In the second study, relationships among the constructs and satisfaction of the service was investigated by using structural equation models. An SEM analysis showed that these six constructs can predict the satisfaction about ubiquitous system, Practical implications and utility of this scale are discussed.
