A Structured Approach for Designing Adaptive Interactive Systems by Unifying Situation-Analytics with Model- and Pattern-Based User Interface Development

This paper discusses the SitAdapt 2.0 development approach for constructing adaptive interactive systems. Resulting applications provide situation-awareness and respond to changing contexts, environments, user emotions, and biometric signals. An observer component is watching the user during interaction with the system. The adaptation process is triggered by situation changes or the recognition of new situations. The necessary software modifications are established in real-time by activating situation rules and exploiting the pattern- and model-based resources of the PaMGIS development framework for model based user interface development. It is shown in detail, how the adaptation process exploits the different PaMGIS models before and during runtime. The SitAdapt approach may also serve for finding user personas, optimizing user experience, and allowing for individualized digital marketing activities. The approach is currently being evaluated for applications from the e-business domain.
