Modeling and Runtime Generation of Situation-Aware Adaptations

Abstract

SitAdapt 2.0 is an architecture and runtime system for building adaptive interactive applications. The system is integrated into the PaMGIS framework for pattern- and model-based user interface construction and generation. This paper focuses on the situation-rule-based adaptation process and discusses the interplay of the SitAdapt 2.0 components in order to support different categories of adaptations. As the system observes the user during sessions and collects visual, bio-physical, and emotional data about the user that may vary over time, SitAdapt 2.0, in contrast to other adaptive system environments, is able to create situation-aware adaptations in real time that reflect the user’s changing physical, cognitive, and emotional state. The operation of the system is demonstrated with an example from an adaptive travel-booking application.
