Persuasive technology is a very recent and emerging topic, which relies on persuasion to support human behavior change voluntarily without coercion and deception.\r\nIn this research, we focus the design of persuasive system for promoting behaviors change with energy as application domain. In the interest of preserving the planet, reducing domestic energy use is necessary for fighting against global warming and climate change issues. The approach to save energy by introducing more efficient appliances only tackles partially the current issues. An urgent need is to motivate sustainable behaviors in energy usage. However, changing people behaviors involves a complex and difficult process.\r\nThe challenge is to design interactive systems that take into account this process dimension and that keep users involved over time in the process of behavior change. Consequently, based on a review of classifications, design spaces and frameworks targeting the design of persuasive systems, we propose the UP+ framework, our first and conceptual contribution. It considers three dimensions: two related to the process aspect of behavior change, at two levels: micro (cause-effect-causality) and macro (long term)); one related to the psychological aspects of motivation.\r\nBased on the UP+ framework, we conduct a state of the art of existing persuasive systems for energy. It reveals that most of these systems covers a few persuasive functions only (e.g., self-surveillance or eco- feedback). In this work, we particularly focus on decision and causality of behavior. A second contribution is the Mondrian User Interface, a proof-of-concept of UI designed to sustain daily use and to keep inhabitants motivated in the long run. We consider thrre goals: to catch user’s attention; to offer multiple levels of user interaction depending on the context of use; to allow the integration of interactional bricks supporting persuasion. Particularly, we propose two bricks, Sliders4DM and Plan4Actions.\r\nIn order to assist inhabitants in preparing a change (decision), Sliders4DM is a novel widget allowing non- specialists to find an appropriate trade-off between (possibly) conflicting criteria in the home via what-if approach. Sliders4DM is evaluated with two experiments: a qualitative one (16 participants) and a quantitative comparative one (177 participants). Plan4Actions is a novel concept of user interface for planning daily actions. The concept is empowered by the co-decision between inhabitants and the home management system. It provides inhabitants with flexibility in planning their daily actions in order to satisfy their objectives in terms of comfort and sobriety. A twofold evaluation presented a favorable assessment from 13 participants about Plan4actions’ comprehension, its usability and potential utility in the domestic context.\r\nWe also discuss the limitations related to persuasive interaction covered by current works and the needs for a long-term evaluation to mesure the behavior changes. The thesis opens new perspectives for extending current research of PIS for energy. To conclude, we define our future works, which involves short-term improvements for current prototype and its deployment in real domestic context.", "year": 2019, "uri": "http://iihm.imag.fr/publication/N19a/", "id": 871, "bibtype": "phdthesis", "abbr": "N19a", "authors": { "1": { "first_name": "Van Bao", "last_name": "Nguyen" } }, "date": "2019-12-05", "document": "http://iihm.imag.fr/publs/2019/Thesis_VB.pdf", "type": "Thèses et habilitations", "booktitle": "Thèse de Doctorat de la Communauté Grenoble-Alpes" }, { "lang": "en", "publisher": "ACM", "doi": "https://doi.org/10.1145/3240167.3240185", "title": "The TOP-Slider for Multi-criteria Decision Making by Non-Specialists", "url": "https://dl.acm.org/citation.cfm?id=3240185", "abstract": "The TOP-Slider revisits the classical slider widget to help non-experts to find optimal compromises between tightly coupled, possibly conflicting, criteria.

However, most approaches and solutions to this problem promote automated and autonomous systems that take full control of the decisions. Although these systems relieve users from setting the temperature in offices and homes, the level of thermal comfort chosen by the technology may not meet the individuals’ requirements. Automating control is an obvious solution but it keeps the human out of the loop. In this paper, an alternative approach is promoted based on system–human cooperation that allows people to make the final decision. However, to make sound decisions, users need to understand the system functioning and rationale and they need to be convinced and motivated to change their habits with regard to energy consumption. Our approach is based on an e-coach system, called Involved, which provides users with contextual explanations along with a user interface designed to persuade the user to stay involved. The results of this research are the development of an early prototype that provides end-users with a 24-hour plan of recommended actions along with contextual explanations that justify each action. This plan satisfies the inhabitant’s preferred compromise between the thermal comfort, air quality and financial cost specified by the inhabitant (i.e. the user) using a novel interaction technique, the Trade-Off-Pareto sliders. Users can edit the plan (e.g. suppress an action), skip some actions, perform additional actions, or even change their preferred compromise, and be informed in real time of the consequences on energy consumption and comfort.
