Enabling Situation-Aware User Interface Behavior by Exploiting Emotions and Advanced Adaptation Techniques

SitAdapt 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 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, 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. With this advanced adaptation process, both, task accomplishment and user experience can be significantly improved. The operation of the system is demonstrated with an example from an adaptive travel-booking application.
