Adaptation and Plasticity of User Interfaces

This paper introduces the notion of plasticity, a new property of interactive systems that denotes a particular type of user interface adaptation. It also presents a generic framework inspired from the model-based approach, for supporting the development of plastic user interfaces. This framework is illustrated with simple case studies. KEYSWORDS. User interface adaptation, plasticity. 1. Introduction: A Design Space for Adaptation In HCI, adaptation is modeled as two complementary system properties: adaptability and adaptivity. Adaptability is the capacity of the system to allow users to customize their system from a predefined set of parameters. Adaptivity is the capacity of the system to perform adaptation automatically with
