The International Workshop on Symbiotic Interaction is the primary venue to present scientific work dealing with the symbiotic relationships between humans and technologies and to discuss the nature and implications of such relationship, including ethics. As such the workshop sets out to address very directly one of the key phenomenon deriving from current developments in data science, automation, artificial intelligence and sensing technologies. For a description of the network of scholars organising the workshop and a definition of what is meant by symbiotic interaction, please visit: symbiotic-interaction.org Early editions of the workshop were organised in Padova (2012, Università di Padova) and London (2013, Goldsmith College). These two workshops were supported by Universities and EU FET project partners to share ideas and extend the collaborative network around this theme. Given the informal nature of these two early events, no proceedings were produced. In 2014, in Helsinki, the workshop acquired a more formal structure and since then its proceedings have been published by Springer in its LNCS series. It then moved to Berlin in 2015 and to Padova in 2016 (whose proceedings were published under an open access license). This year the workshop is held in Eindhoven, at the center of Europe.
