User interface migration based on the use of logical descriptions

In this chapter we present a solution for both total and partial migration of Web applications. Such solution is based on the use of multiple abstraction levels for describing UIs, and a set of transformations that allow the migration of user interface components selected by the user to another device. Differently from total migration , where the entire UI is migrated, partial migration is the possibility to select the parts of the UI to be migrated. This feature is particularly useful in complex Web applications, such as various emerging mash-up applications. We also show an example of application of our solution to a Web social game , and report on its evaluation.
