Designer as Mediator: An Innovative Model for Designing Interactive Devices within the User-Centered Approach

This study aims to explore interface design in its early stages. It also seeks to explain how the designer can actively modify the vision of a multidisciplinary project team in order to promote the transfer of knowledge. This is to ensure that the design activity is focused on users. This reflection is supported by case studies from which we propose a new design model geared to facilitate collaboration and exchange of information amongst contributors. The model permits the appropriation of knowledge, while positioning the user at the center of the design process.
