Using Context-Awareness to Foster Active Lifestyles

摘要

This paper describes a context-aware mobile application which aims at adaptively motivating its users to assume active lifestyles. The application is built on a model which combines 'motion patterns' with 'activity profiles', in order to evaluate the user's real level of activity and decide which actions to take to give advice or provide feedback. In particular, a 'move-to-uncover' wallpaper puzzle interface is employed as motivating interface; at the same time, context-aware notifications are triggered when low activity levels are detected. In order to accelerate the application's design and development cycle, a mobile service oriented framework - CASanDRA Mobile - has been used and improved. CASanDRA Mobile provides standard features to facilitate context acquisition, fusion and reasoning in mobile devices, making easier access to sensors and context-aware applications cohabitation.
