Most of the research conducted on persuasive technologies (or persuasive interactive systems) is based on Fogg’ work (Fogg, 1999, 2003; Fogg, Cuellar & Danielson, 2009; Fogg & Eckles, 2007). According to Fogg, persuasion through information and communication technologies takes place at two levels: micro and macro. At the micro level, technologies may not have a persuasive outcome as the overall goal, but they may incorporate elements of influence. Micro persuasion can be incorporated into dialogue boxes, visual elements, interactive sequences which can lead to better performances or behaviour changes. This is the case with Word spelling and grammar checker, which helps you identify your spelling and grammar errors, and provides you with propositions. For Fogg, a system that reminds you to do something, which allows you to visualize your activity or encourages or praises you is a micro persuasive technology because it changes the way you think and the way you behave. On the other hand, the main goals of Web sites such as Amazon.com or ebay.com are to persuade users to buy. These sites are examples of macro persuasion. But commerce is not the one and only issue of the macro persuasive technologies. Every aspect of the daily life is concerned (education, energy conservation, sport activities, food, ecological driving, sustainability, smoking cessation, etc.)...

1. Persuasion and Influence: attitude change and behavior change

Fointiat, Valérie ; Barbier, Laura.
The study of the socio-psychological processes involved in persuasion is onethe pivotal topics in social psychology. Eight decades ago, researchers from Yaleuniversity were the first in studying the mechanism of persuasion in the specificcontext of World War ll. Persuasion is obtained when the receptor of communicationmakes a change in his mind that is when a change in attitude occurs. Logically, such achange in attitude should imply a change in behavior. The research on behavioralchange show that it is not systematically the case. Thus changing what people think isnot changing what people do (or what people will do). This shortcut could biased theconclusions of researches, in the large domain of persuasion as well as in the morerestricted domain of the persuasive technologies. In conclusion, we would like topromote a theoretical, methodological articulation between HMI and social psychology.

2. State of the art in persuasive systems design

Foulonneau, Anthony ; Calvary, Gaëlle ; Villain, Eric.
By their ability to change person's behaviors and attitudes, persuasive technologies appear as promising for overcoming societal challenges. They are based on theories and models from cognitive psychology and social psychology. The earlier works on persuasive technologies, by Fogg, identified many persuasive principles to influence user's behaviors and attitude, and thus useful for building persuasive systems. Studies on persuasive technologies also bring design methods, architectures, persuasive interfaces, and experimentation in numerous domains. The grand challenge is now to adapt persuasion to the complexity and versatility of each individual, thereby maximizing the persuasive effectiveness. We still have to build plastic persuasive technologies.

3. Persuasive Technology and Energy: critical analysis of the state of the art

Cano, Grégory ; Laurillau, Yann ; Calvary, Gaëlle.
This paper presents a state of the art and an analysis of existing works dedicated to persuasive technologies for energy consumption. Thanks to a systematic analysis, a set of concepts of persuasion has been identified and organized into a six dimensional design space. In particular, the concept of persuasion function is identified and defined. Six persuasion functions are identified: Mirror, Explain, Recommend, What-if, What-for, Suggest-and-Adjust. This design space is used to characterize the works considered in this state of the art.

4. Evolution of the heuristic inspection: towards an integration of accessibility, usability, emotion and persuasion?

Brangier, Eric ; Desmarais, Michel ; Alexandra, Nemery ; Prom Tep, Sandrine.
This research investigates the issue of conducting heuristic inspections along an extended array of dimensions that includes often ignored considerations such as motivational and persuasive factors. Two objectives are pursued: to offer a comprehensive perspective on the different approaches to heuristic inspections and their evolution in the last decades since their emergence, and to propose an approach that integrates the extended array of heuristic criteria. The motivation for the proposed approach and the issues faced are also discussed.

5. Experimental validation of persuasive criteria for CHI: analysis of their effectiveness to inspect persuasion in interfaces

Brangier, Eric ; Alexandra, Nemery ; Séverine, SCHMITT.
The objective of this article is to present a study that has been made about the use of the interactive persuasion criteria grid in order to identify persuasiveelements in the interfaces. Two groups have been created, “criteria” and “control”. Both should identify persuasive elements of two interfaces: social network (Facebook) and e-commerce (Cdiscount). During the second phase of the experiment, the “criteria” group had an access to the grid. 27 participants were recruited for this study. The results show that the participants have found more persuasive elements with the grid and that the identification performance was better for the e-commerce website. The average evaluation performance is significantly different (p = 0.000) on the two sites. On Facebook, participants' performance was 9.7% ("control" group) and 23.8% then ("test" group); and for Cdiscount respectively 21.7% ("control" group) and 43.6% ("test" group). The set of guidelines […]

6. Systèmes ludo-persuasifs pour la consommation durable. 1 -Points de repères et défis à relever

Senach, Bernard ; Negri, Anne-Laure.
For over 40 years, it is common knowledge that industrial society has to reduce its energy consumption. Most of people are now aware that this change is necessary. However, commitment to action is still difficult and there is substantial work to be done. Attention has turned to Human and Social Sciences, as a deeper understanding of behaviors' determinant and use of influence principles could help to speed up behavior changes. New technical devices combining game design, interaction techniques and persuasion have emerged but the field is still in its infancy. This article gives a glimpse at a toolbox helping to design and evaluate interactive persuasive devices and discuss five main challenges. This work is extended by two others papers: Negri et Senach (2015b) provide a first grid of persuasion principles and in Senach et Negri (2015c), these grid have been applied to assess the persuasive properties of an energy challenge within a company.

7. Ludo-persuasive systems for sustainable consumption. : . 2 – Elaboration of a ludo-persuasive principle grid

Negri, Anne-Laure ; Senach, Bernard.
Ludo-Persuasive Systems (LPS) are systems which are designed with the intent of changing people's behavior or attitude. As highlighted in Senach and Negri (2015a), such systems are based on two converging fields-gamification and persuasive technologies-but their engineering still is in its infancy. In this chapter, the authors build on existing lists of persuasive and gamification principles and integrate the various works ((Fogg, 2003) (Oinas-Kukkonen and Harjumaa, 2009) (Nemery, 2012)) in order to provide a grid that can be seen as a first tool in a LPS toolbox. The proposed grid is to be used both as a design and an evaluation tool. It was tested in the post-mortem analysis of an energy saving challenge described in Senach and Negri (2015b). The paper starts with discussions on the method followed to select, cluster and assess the implementation of the principles; it then defines the ludo-persuasive principles by providing examples and hints for identifying ludo-persuasive […]

8. Ludo-persuasive systems for sustainable consumption: 3 – Analysis of the potential of a ludo persuasive energetic challenge in companies

Senach, Bernard ; Negri, Anne-Laure.
L'articulation des nouvelles technologies de l'information et de la communication (NTIC) avec les modèles de changements comportementaux développés dans les Sciences Humaines et Sociales (SHS) joue un rôle de plus en plus important pour le développement durable. Dans les sociétés avancées, il est nécessaire de modifier radicalement nos modes de vie et, dans les sociétés dites émergentes, l'impératif est l'adoption de modes de développement alternatifs. Les NTIC ont ainsi trouvé un champ d'application privilégié dans le contexte de la réduction des consommations énergétiques. Plusieurs challenges énergétiques ont été conduits aussi bien avec le grand public qu'avec les employés d'entreprises. L'évaluation de l'efficacité de ces dispositifs ne dit généralement pas grand-chose de leurs qualités intrinsèques, de leurs défauts, de leurs faiblesses. L'article propose une analyse détaillée des caractéristiques […]
