    We propose here to highlight the benefits of building a framework linking Kansei Design (KD), User Centered Design (UCD) and Eco-design, as the correlation between these fields is barely explored in research at the current time. Therefore, we believe Kansei Design could serve the goal of achieving more sustainable products by setting up an accurate understanding of the user in terms of ecological awareness, and consequently enhancing performance in the Eco-design process. In the same way, we will consider the means-end chain approach inspired from marketing research, as it is useful for identifying ecological values, mapping associated functions and defining suitable design solutions. Information gathered will serve as entry data for conducting scenario-based design, and supporting the development of an Eco-friendly User Centered Design methodology (EcoUCD).ANR-ECOUS

    Using environmental segmentation to perform ecodesign with users

    International audienceMarket segmentation has been a crucial point for enhancing the success of new products. By grouping users with similar needs, manufacturers have been able to design products with much more appeal to a specific typology of users. Moreover, ecodesign process strives at developing products with lower impact on the environment. Actual ecodesigned products however do not completely fit with users needs. This contribution proposes to use the segmentation approach to drive the process of product ecodesign. By differencing the users according to their sensitivity to environmental issues, this approach enables to design environmentally friendly products for a specific group. To this end, we intend to couple an existing segmentation definition for environmental policy with the Rokeach Values System. The result is a seven group representation of users with a specific set of values for each group that will allow developing products that match user needs with the environmental consciousness. This segmentation and its benefits are applied to the adaptation of ecodesign strategies according to each users group. We illustrate our proposal with an application to the design of a coffee machine

    La prise en compte des enjeux environnementaux est un sujet trĂšs prĂ©sent dans notre sociĂ©tĂ© actuelle. Dans le domaine du dĂ©veloppement de produits, l'Eco-conception est une dĂ©marche qui permet la considĂ©ration de ces enjeux en proposant de rĂ©duire les impacts environnementaux des produits tout au long de leur cycle de vie. La phase d'utilisation du cycle de vie est une Ă©tape cruciale puisque le mode d'utilisation des produits peut avoir des consĂ©quences non nĂ©gligeables sur leur performance environnementale. Nous proposons dans cette thĂšse d'enrichir la comprĂ©hension de cette phase d'utilisation en mettant en Ă©vidence les composantes Kansei qui jouent un rĂŽle dans l'interaction de l'utilisateur avec le produit et qui peuvent ĂȘtre intĂ©grĂ©es en amont de la conception de produits Ă  faible impact environnemental. Notre dĂ©marche permet de mieux renseigner la phase d'utilisation, contribuant ainsi Ă  la maitrise de la performance environnementale des produits. Nous dĂ©montrons Ă  travers notre recherche que l'utilisateur peut ĂȘtre dĂ©fini, non seulement par des informations basiques que nous retrouvons communĂ©ment dans la Conception CentrĂ©e Utilisateur, mais Ă©galement Ă  partir d'informations subjectives apportĂ©es par la dimension Kansei. A travers nos expĂ©rimentations, nous mettons en application deux attributs EcoKansei correspondants aux valeurs et aux Ă©motions afin d'illustrer la modĂ©lisation utilisateur pour la conception de produits Ă  faible impact environnemental. L'approche que nous proposons vient en complĂ©ment au projet EcoUse qui vise Ă  dĂ©velopper une mĂ©thodologie d'Eco-conception centrĂ©e utilisateur. Les apports de notre dĂ©marche sont multiples. Du point de vue de la recherche, une mise en relation de l'Eco-conception et du Kansei, qui sont Ă  la base complĂštement dĂ©connectĂ©es entraine un enrichissement mutuel entre ces deux approches. Du point de vue industriel, une dĂ©marche d'Eco-conception appuyĂ©e par les Ă©tudes Kansei doit permettre la conception de nouveaux produits qui auront l'avantage d'ĂȘtre Ă  la fois mieux acceptĂ©s par les utilisateurs car en adĂ©quation avec leur sensibilitĂ© environnementale et en mĂȘme temps moins impactants pour l'environnement.The consideration of environmental issues is a very strong topic in our society nowadays. In the field of Product Development, Ecodesign is a methodology that allows the consideration of these issues by proposing to reduce the environmental impacts of products throughout their life cycle. The use phase of the life cycle is a critical step as the way how the products are managed can have significant impact on their environmental performance. We propose in this thesis to enrich the understanding of the use phase by highlighting the Kansei Information that can play a major role in the interaction between the user and the product and thus can be integrated in the early phase of the Ecodesign process. Our approach provides a better understanding the use phase, by contributing to the mastery of the environmental performance of products. Our research points out that the user can be defined not only from basic information commonly used in the User Centered Design, but also from subjective information brought by the Kansei dimension. We carry out experiments in which we implement two EcoKansei attributes corresponding to the values and emotions in order to illustrate user modeling for Ecodesign. The approach we propose is a part of EcoUse project that aims to develop a methodology for user-centered Ecodesign. Various contributions of our approach can be pointed out. For the Research, linking Ecodesign with the Kansei studies, which are basically unconnected leads to mutual enrichment between these two approaches. For Industry, an Eco-design approach supported by Kansei Information enables the design of new products which will have the benefits of both providing less impacts to the environment, and at the same time being more accepted by users as these products match with their environmental sensitivity
