Our interdisciplinary team develops online solutions for participatory processes in urban environments. We direct urban interventions and public events that support the activation of participants on-site. Recently our group published the platform “Handshake” and conducted the implementation of Unortkataster Köln in collaboration with local citizens. Act-Local is a spin-off from EU-founded research project Citizen Media at Academy of Media Arts Cologne (Lab3) and was founded in July 2009.
