Apply different theories and methods of behavior change to develop a concept.


Dreamr: An interactive and intelligent mirror to persuade children to be less aversive going to bed


Creativity & Aesthetics, User & Society


This study was conducted as part of the Master’s elective Design for Behavioral Change”, taught at the faculty of Industrial Design at the Eindhoven University of Technology. The main goal was to become familiar with several persuasive theories, models and frameworks. By applying the techniques in a design case the authors were able to go into depth of some of these theories and frameworks. The paper shows the development of a persuasive design. During the process, the design has gone through three major iterations. The final result is Dream: an intelligent mirror that persuades boys between six and nine to be less aversive towards going to bed. The design is heavily based on the
Trans Theorotical Model and the Self Determanation Theory, and uses aspects of three di erent persuasive frameworks: Cialdini’s six Principles of Influence, B.J. Fogg’s Functional Triad and the Design with Intent cards. The paper argues why the design would work from a theoretical point of view.



Key learning points: persuasive principles, social science, behavior change

The course gave an overview of different theories and frameworks for persuasive design. They can be used to understand behaviour, design for a persuasive intent and using heuristics to evaluate a design. The course also provided information on how to measure and evaluate behaviour by the creation of an evaluation plan. The acquired knowledge and tools could be directly used in my project about community design. I could link the theories and frameworks to examples in my own life and current understanding of behavior. The strong psychological base the course provided will help to ground and communicate my designs better. I used Cialdini’s principles and the Self Determination Theory for my FMP and persuade crowdworkers for better evaluations. The course was essential to understand the underlaying principles behind UX Design.
