Penser "plasticité" peut améliorer la qualité des interfaces homme-machine: une étude de cas

In Human-Computer Interaction, plasticity refers to the capacity of User Interfaces (UI) to adapt to the context of use () while preserving user-centered properties. Until now, plasticity was the scope of various studies. The adaptation from a context of use to another was studied in order to satisfy the end-user's requirements. This paper changes the focus: plasticity in itself is not the scope anymore; it is viewed as a way for designers to improve UI quality. The iterative design process is detailed for a case study where all design decisions have been recorded in terms of their influence on UI ergonomic quality. The case study deals with e-goverrment procedures. The return of experience shows that paying attention to plasticity for a small screen platform results in improvements on the large screen platform version due to the reexamination of its initial design.
