Mobile-centric ambient intelligence refers to systems, where personal mobile device is used to access ambient information and services. In this paper, we present three scenarios describing how independent living of elderly can be supported with mobile-centric ambient intelligence services. The scenarios have been prepared in the MINAmI project, which is developing an open technology platform for mobile-centric ambient intelligence. The scenarios focus on supporting self-care and safety at home. The three scenarios have been evaluated by groups of elderly people and the two self-care related scenarios also by medical experts, in both Spain and Finland. We report the results of these evaluations, and draw conclusions for user acceptance of mobile-centric ambient intelligence supporting independent living of the elderly.
