Engineering interactive systems that are aware of the characteristics and constraints of the context of the user becomes challenging when several user's profiles, platforms and environments are considered. In this sense the adaptation of user interfaces raises as an important approach for stakeholders aiming at implementing and providing systems whose user interfaces are usable, regardless of their context of use. In 2012 during the first CASFE workshop we discussed potential models, frameworks and practical applications that aim at supporting, facilitating and improving the development of adaptive and adaptable systems. CASFE'2013 aims at joining experts in the domain of context-aware adaptation in order to present and discuss its state-of -the-art.
