A Concerted Model-driven and Pattern-based Framework for Developing User Interfaces of Interactive Ubiquitous Applications.

Modeling and building interactive user interfaces ( UI) typically requires the skills of software developer s and HCI experts who cooperate with platform and marketing experts in order to arrive at solutions with the required s oftware quality, usability, and user experience. The combin ation of model-driven user interface development practices w ith pattern-based approaches that specify HCI- and soft warepatterns in a formalized way and respect emerging standards offers potentialities to facilitate and a t least partially automate the user interface development p rocess, therefore reduce the time-to-market and development costs, and lead to solutions that can easily be adapted to varying contexts and target devices. Such pattern-aided UI adaptation is not limited to design time decisions but can also be applied during runtime. This paper highligh ts the architecture and capabilities of the Pattern-Based Modeling and Generation of Interactive Systems (PaMGIS) framework to broadly support the construction and adaptation of user interface models. It is discusse d, how pattern descriptions that capture important parts o f the design knowledge should be organized in order to be automatically processed during the modeling process .
