Challenges to the model-driven generation of user interfaces at runtime for ambient intelligent systems

Context-awareness, personalization and adaptation are among salient features of Ambient Intelligent (AmI) Systems. The User Interfaces (UI) in AmI environments should therefore also be dynamic at runtime. Developing such UIs is challenging since many aspects have to be considered. Most existing approaches follow Model-driven Engineering (MDE) as a solution. However, they only address design time issues. We successfully applied MDE for runtime generation of UI in the BelAmI project but encountered challenges that we presented in this paper. Possible solutions have also been discussed.
