Understanding continued ubiquitous decision support system usage behaviour

With the recent surge in the use of ubiquitous computing devices, users are carrying their own ubiquitous decision support systems (UDSS) and making important decisions using them. UDSS enables decision makers to access mobile networks to acquire information at anytime, anywhere. However, there have been few studies investigating why UDSS users intend to use the systems continuously, as there would be a large number of elements to take into consideration. The specific factors of the UDSS that this study focuses on include the connectivity and context-awareness function, which were not considered in previous research on the adoption of UDSS. Accordingly, this study empirically explores this research question by using the scanphone-based ubiquitous delivery system (UDS), which many delivery service providers have been adopting recently as a form of the ubiquitous decision support system (UDSS). The results reveal that connectivity, context-awareness function, and perceived values play meaningful roles in the UDSS. Based on these results, this study suggests implications and directions for future research to enable the planning and realization of the future UDSS.
