“…By analogy, an interactive system is close-adaptive for the contexts of use that fall within its domain of plasticity [4], that is, for the contexts of use for which this system can adapt on its own. By design, an interactive system has an innate domain of plasticity.…”

Abstract. User Interface (UI) plasticity denotes UI adaptation to the context of use (user, platform, physical and social environments) while preserving usability. In this article, we focus on the use of Model-Driven Engineering and demonstrate how the intrinsic flexibility of this approach can be exploited by designers for UI prototyping as well as by end-users in real settings. For doing so, the models developed at design-time, which convey high-level design decisions, are still available at run-time. As a result, an interactive system is not limited to a set of linked pieces of code, but is a graph of models that evolves, expresses and maintains multiple perspectives on the system from top-level tasks to the final UI. A simplified version of a Home Heating Control System is used to illustrate our approach and technical implementation.

“…The subset of this domain for which usability is preserved is called plasticity domain (Calvary et al, 2001b). Considering that adaptation may consist in either tuning the interactive system to target the new context of use (in this case, the interactive system ISi switches from configuration Cj to configuration Ck.…”

“…An entry point marks a level of reification at which the development process (reification and/or translation) may be began. Unlike the initial process that contained an entry point only (the task oriented specification) (Calvary et al, 2001b), the unifying reference framework foresees entry points at any level of reification: for example henceforward the designer may start at the abstract user interface without having produced the task oriented specification; -Horizontal transformations, such as those performed between HTML and WML content descriptions, correspond to translations between models at the same level of reification. A translation is an operation that transforms a description intended for a particular target into a description of the same class but aimed at a different target.…”

This paper describes a framework that serves as a reference for classifying user interfaces supporting multiple targets, or multiple contexts of use in the field of context-aware computing. In this framework, a context of use is decomposed in three facets: the end users of the interactive system, the hardware and software computing platform with which the user have to carry out their interactive tasks and the physical environment where they are working. Therefore, a context-sensitive user interface is a user interface that exhibits some capability to be aware of the context (context awareness) and to react to changes of this context. This paper attempts to provide a unified understanding of context-sensitive user interfaces rather than a prescription of various ways or methods of tackling different steps of development. Rather, the framework structures the development life cycle into four levels of abstraction: task and concepts, abstract user interface, concrete user interface and final user interface. These levels are structured with a relationship of reification going from an abstract level to a concrete one and a relationship of abstraction going from a concrete level to an abstract one. Most methods and tools can be more clearly understood and compared relative to each other against the levels of this framework. In addition, the framework expresses when, where and how a change of context is considered and supported in the context-sensitive user interface thanks to a relationship of translation. In the field of multi-target user interfaces is also introduced, defined, and exemplified the notion of plastic user interfaces. These user interfaces support some adaptation to changes of the context of use while preserving a predefined set of usability properties.

“…Although the properties developed so far in HCI [Gram and Cockton 1996] provide a sound basis for characterizing usability, they do not cover all aspects of plasticity. In [Calvary et al 2001] we propose additional metrics for evaluating the plasticity of user interfaces.…”
