Méthodes et outils de conception participative avec des utilisateurs non-voyants

Participatory Design is a process for the design of interactive systems integrating the user in all design phases. However it is based on the assumption that users are in possess of their full physical capabilities, in particular the visual sense, and thus is for the most part not adapted for working with visually impaired people. In this article we present an approach for using participatory design when working with blind people. We start with an analysis of the existing methods, in which we discuss their limits concerning accessibility for the blind, and the peculiarities of blind users. Afterwards we present how we have adapted the classical design methods during our design process and we show the results of our project. We conclude with some recommendations and future working propositions.
