The document describes SmartAssist, an open platform and infrastructure for ambient assisted living (AAL) services. SmartAssist aims to provide interfaces for external service providers to access user profile and sensor data, and integrate their services. It uses an extended OpenSocial API and the Ambient Dynamix framework to connect Android devices. An example application called BikeWars is presented, which is a serious gaming application that adapts its difficulty level based on individual users' social data like age and gender retrieved from the SmartAssist platform.
