Now that the candidate for the EPFL Learning Center is chosen, documents can be put on-line. Last year, I work with Pierre and David on interaction design scenarios and user personas. Basically the idea was to imagine the different potential 'users' of the building: students, teachers, phds and visitors. Then we envisioned their activities there during one day. The point was to show the architects what should be the building: a fruitful context to support learning, work as well as access to resources. The document can be found here (.pdf, in french).
