This section introduces the main concepts in which the developed work is based on.
Whereas the proposed process aims at supporting the development of adaptive rich
interfaces for interactive applications, Section 2.1 briefly presents the concepts related to
Web 2.0 and Rich Interfaces. Section 2.2 deals with concepts associated with Model-Based
User Interface Development, employed in the static content adaptation part of the hybrid
adaptation approach applied in the process. Since the dynamic interface adaptation part
relies on contextual information obtained at runtime, Section 2.3 broaches the conceptions
regarding Context-Sensitive Applications.
