ABSTRACT
Adaptation of User Interfaces (UI) to context of use is becoming a major issue in HCI. By context of use, we mean the <user, platform, environment> triplet. Plasticity refers to the ability of UIs to withstand variations of context of use while preserving usability. Based on a reference framework that provides designers with a powerful tool for reasoning about plasticity, this paper addresses plasticity at the level of interactors. Comets (COntext sensitive Multi-target widgETS) are a new kind of widget that support adaptation at any level of abstraction: concepts and tasks, abstract, concrete and final UIs. This paper proposes a model as well as run-time software mechanisms that support the design of comets as well as run-time adaptation. Run-time is ruled according to a set of strategies and politics.
