DinerRouge: Bringing Wealth and Income Inequality to the Table through a Provocative UX

Income and wealth inequality is one of the important social issues of the last decade. Nevertheless, it is rarely discussed through the lense of Human Computer Interaction. In this paper, we aim at investigating how a provocative user experience can contribute to engaging users when it comes to issues about wealth and income inequality. More precisely, we present the design of DinerRouge, a novel mobile application that can spark income inequality discussion by providing a provoking way to split the bill in restaurants based on income. We conducted a preliminary evaluation of DinerRouge with 78 participants which convey the fact that DinerRouge is usable, provocative and informative. Finally, we present open research question to guide future investigations.
