Titre : Approach to citizen co‐design in the processes of innovation by uses: the case of the Ecofamilies project Auteurs : Franck Debos, Céline Masoni Lacroix, Natacha Cyrulnik, Paul Rasse, Brigitte Trousse, Revue : Information, Organization, Knowledge Numéro : Issue 1 Volume : 1 Date : 2017/10/5 DOI : 10.21494/ISTE.OP.2019.0379 ISSN : 2632-6450 Résumé : The authors place their article in a context of societal innovation, which puts users at the center of the project approach in terms of the energy theme. Interested in a typology of existing co-design approaches, they propose a feedback from the Ecofamilies participatory project, which involved participating families, co-design and test a technological solution for monitoring domestic energy consumption, The Human-Machine Interaction plan, in line with their needs. The authors will examine the contributions, constraints and limits of the commitment of a co-design approach from the perspective of the evolution of the users towards their positioning as actors of a collaborative project and the processes of Collective intelligence.
