@ARTICLE{10.21494/ISTE.OP.2019.0379, TITLE={Approach to citizen co‐design in the processes of innovation by uses: the case of the Ecofamilies project}, AUTHOR={Franck Debos, Céline Masoni Lacroix, Natacha Cyrulnik, Paul Rasse, Brigitte Trousse, }, JOURNAL={Information, Organization, Knowledge}, VOLUME={1}, NUMBER={Issue 1}, YEAR={2017}, URL={https://www.openscience.fr/Approach-to-citizen-co-design-in-the-processes-of-innovation-by-uses-the-case}, DOI={10.21494/ISTE.OP.2019.0379}, ISSN={2632-6450}, ABSTRACT={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.}}
