This information day will focus on the new research and innovation area "Collective Awareness Platforms for Sustainability and Social Innovation" (CAPS) under the ICT workprogramme 2013. CAPS are ICT systems leveraging the emerging "network effect" by combining open online social media, distributed knowledge creation and data from real environments (Internet of Things), in order to create new forms of social innovation. They are expected to support environmentally aware, grassroots processes and practices to share knowledge, to achieve changes in lifestyle, production and consumption patterns, and to set up more participatory democratic processes.The event will provide first-hand information on the call, discuss some initial examples, and give voice to any participant interested in presenting and discussing her/his own ideas on the subject. Participation is free of charge.
