AALIANCE2 Project is a Coordination Action funded in the FP7-ICT-2011.7, which focuses on the Ambient Assisted Living (AAL) solutions based on advanced ICT technologies for ageing and wellbeing of elderly people in Europe. One of its main objectives is to build consensus upon research priorities in the AAL roadmap and Strategic Research Agenda for the upcoming decades. This second workshop will focus on five enabling technologies, i.e. sensing, reasoning, acting, interacting and communicating, and in particular on how these technologies could support people, or should be developed to do so, according to previously described AAL activities and scenarios. The workshop objectives are to probe and build on the contents of the first AALIANCE Roadmap, published in March 2010, to design a new improved and enriched AALIANCE2 Roadmap.
