Elaboration, validation et application de la grille de critères de persuasion interactive

Abstract : Interface designer have a constant need to influence users. In any field, from sales to ecology through education, interfaces are more and more smart, adaptive and interactive in order to encourage people to change their attitude or behavior. If ergonomic inspection and usability has long been considered to be a part of the evaluation phase or product design process, persuasive technology has not yet been taken into account. However, it represents an emerging field and has already proven results in many research and applied to many substrates. It is part of the overall user experience. Faced with the lack of validated tool in this area, a set of criteria was elaborated. Following the review of 164 articles on the captology field, a grid of eight criteria was proposed and contains: credibility, privacy, personalization, attractiveness, solicitation, initiation, commitment and ascendency. This grid is also composed by 23 sub-criteria. It differs from the size of a static or all of the qualities that an interface should have in order to be conducive to the establishment of a loop engaging. This grid follows an inductive method and is based on an iterative design process taking into account the expert opinion in Human-Machine Interaction. Following various pre-test and its stabilization, this list of criteria was tested with 30 experts in ergonomics to proceed to its validation. Experience-based identification task called persuasive elements in interfaces; 15 have been chosen. The use of the grid showed that it helped the experts identify 78.8% of persuasive elements. With a Kappa score of 0.76, a strong inter-judges agreement has been demonstrated. Following this validation in the laboratory, a real experience test to prove its effectiveness in the field has also been conducted. After its first use as an assessment tool, the grid was used as an aid in the design of interfaces to be most influential. Applied in the context of an online survey company, annual use of the criteria increased the number of respondents from 25% to 41% in a population of 897 employees. Finally, intelligence has specific features to the world of professional software. Development work of two tools helped to advance reflection on the elements of persuasion to their own interactive business intelligence.
