C3Places aims at developing strategies and tools to increase the quality of public open spaces through Information and Communication Technologies (ICT) by influencing positively co-creation and social cohesion effects. It will explore the new dynamics of open spaces as a service for community and expand our knowledge on how meditated public open spaces function paying attention to local stakeholders, context and different social groups. In the last decade ICT have grown into an important social medium. People build and maintain the relationships through various social media, and increasingly this affects the way they organise their everyday lives and how they use the city and its spaces. On the other hand, diversity of public open spaces is critical for cultural identity, as they provide important gathering points in the urban fabric, offer the place for interactions among generations and ethnicities. People of all ages still need contact with nature and with other people, to develop different life skills, values and attitudes, to be healthy, satisfied with their lives and environmentally responsible. C3Places will generate knowledge and know-how for a co-creation approach to be used to merge the use of ICT with these essential functions of the public spaces.
