Premiers retours d'expérience sur l'utilisabilité et les usages de systèmes interactifs plastiques

Abstract

The Plasticity property has been introduced in 1999 in France to cope with the new variability of the context of use in ambient intelligence. A User Interface (UI) is said to be plastic if it is able to adapt to its context of use while preserving human-centered properties. Ten years later, theoretical as well as practical advances have been made. However, several questions related to usability and acceptability of plastic UIs need to be answered through evaluation with users. This paper presents a state of the art in plasticity and evaluation (methods and concerns). It describes three demonstrators and presents first results from evaluations led in laboratory and in the wild.
